3D animation of ambient occlusion enabled on the animation to the right. In the absence of hardware-assisted ray traced ambient occlusion, real-time applications such as computer games can use screen space ambient occlusion (SSAO) or horizon-based ambient occlusion (HBAO) as a faster approximation of true ambient occlusion, using pixel depth rather than scene geometry to form an ambient occlusion map. Ambient occlusion is related to accessibility shading, which determines appearance based on how easy it is for a surface to be touched by various elements (e.g., dirt, light, etc.).

|
There are parallels between Bilateral Balanced Occlusion (BBO) and canine guided occlusion in complete dentures in that there are simultaneous contacts in centric occlusion. The two concepts of occlusion in complete dentures differ during eccentric movements. Arguments for canine guided occlusion in complete dentures have been gaining momentum because of its ease of fabrication and better patient preference. There has been a presumption that canine guided occlusion in complete dentures promotes denture instability by introducing interferences during function.
|
|
As a result, the Non-Balanced occlusion concept was conceived as an alternative to the balanced occlusion scheme.
|
|
Many ambiguous images are produced through some occlusion, wherein an object's texture suddenly stops. An occlusion is the visual perception of one object being behind or in front of another object, providing information about the order of the layers of texture. The illusion of occlusion is apparent in the effect of illusory contours, where occlusion is perceived despite being non-existent. Here, an ambiguous image is perceived to be an instance of occlusion.

Occlusion according to The Glossary of Prosthodontic Terms Ninth Edition is defined as 'the static relationship between the incising or masticating surfaces of the maxillary or mandibular teeth or tooth analogues'. When exploring different complete denture occlusal schemes, it is more useful to define occlusion as the relative movement of one object to another viz the dynamic relationship between mandible to the maxillae during function. Bilateral balanced occlusion and non-balanced occlusion are two separate entities that make up complete denture occlusion. Bilateral balanced occlusion is observed when simultaneous contacts achieved in both centric and eccentric positions.
|
|
Lingualized occlusion is defined as a form of denture occlusion that articulates the maxillary lingual cusps with the mandibular occlusal surfaces in centric, working, and non-working mandibular positions. The concept of lingualized occlusion was again influenced by Gysi, when he designed a crossbite posterior teeth model concept. He observed that more than half of edentulous patients at the University of Zurich had a posterior crossbite following normal physiological residual ridge resorption. In addition, a lingualised occlusion overcame the difficulties of setting up teeth in the prosthetic laboratory according to a bilateral balanced occlusion.

Dr. Lischer translated The Diagnosis of Dental Anomalies by German orthodontist Paul Simon. This textbook was regarded as the introduction of gnathic system as an aid to orthodontic treatment to United States. Lischer introduced the terms neutro-occlusion, mesio-occlusion and disto-occlusion to describe different varieties of malocclusion. In 1909 he published a textbook called Elements of Orthodontia.

When such are taken to the extreme, the resulting occlusal schemes are essentially the lingulized occlusal scheme, or the Frush linear occlusion. All the concepts discuss the inclination of the condyle and the teeth in one orientation, predominantly in the sagittal direction. Establishing balanced occlusion bilaterally is difficult because any change in the angulation of the teeth or the curve in buccolingual direction will affect the anteroposterior angulation, hence the difficulty in establishing the balance occlusion inside the patient's mouth. There are many variables that may influence the outcome of balanced occlusion.
|
|
This occlusal scheme was first described by Dr. M. M. DeVan in 1951. Monoplane occlusion involves having non-anatomic denture teeth with a 0˚ incisal guidance angle, arranged on a flat occlusal plane. As a consequence, when patients with monoplane occlusion occlude anteriorly, an interocclusal gap appears posteriorly. This is termed the 'Christensen phenomenon' and forms the basis for categorising monoplane occlusion as non- balanced.

|
While, questioning this concept may be ignorant, criticizing this technique does not mean it does not work on a clinical level. Other studies show that there is another occlusion scheme that can be considered in place of the balanced occlusion.

Coronary vasospasm is a sudden, intense vasoconstriction of an epicardial coronary artery that causes occlusion (stoppage) or near-occlusion of the vessel. It can cause Prinzmetal's angina. It can occur in multiple vessels. Atropine has been used to treat the condition.
|
|
Trapozzano then developed the triad of occlusion after carefully analysing Hanau's 5 factors of occlusion. He eliminated the plane of orientation and compensating curves from the Hanau's five main factors. The reason for this was because of the high variability of this plane within the available ridge space. Trapozzano also stated that there is no need for compensating curves as an alteration in the cuspal angles will result in balanced occlusion.

Recently, efforts have been made to propose alternative treatments of amblyopia that do allow for the improvement of binocular sight, for example using binasal occlusion or partially frosted spectacles in place of any eye patch, using alternating occlusion goggles or using methods of perceptual learning based on video games or virtual reality games for enhancing binocular vision. A 2014 Cochrane Review sought to determine the effectiveness of occlusion treatment on patients with sensory deprivation amblyopia, however no trials were found eligible to be included in the review. However, it is suggested that good outcomes from occlusion treatment for sensory deprivation amblyopia rely on compliance with the treatment.
|
|
Historically, complete denture occlusion adopted a balanced occlusal scheme (i.e. balanced articulation: 'the bilateral simultaneous occlusal contact of the anterior and posterior teeth in excursive movements' synonyms bilateral balanced occlusion. Indeed, the bilateral balanced occlusion (BBO) scheme was adopted for reconstruction of dentate patients by both the gnathology school working on the West Coast of America and the Pankey-Mann Schuyler group working on the East Coast of the United States of America observed that using a balanced occlusion in dentate patients was suboptimal, in that this was associated this with restoration failure and cheek biting. There has been a gradual erosion for this approach for both dentate and edentulous patients.
|
|
Traumatic injury to an extremity may produce partial or total occlusion of a vessel from compression, shearing, or laceration. Acute arterial occlusion may develop as a result of arterial dissection in the carotid artery or aorta or as a result of iatrogenic arterial injury (e.g., after angiography).
|
|
Most observers agree that a 90% occlusion is necessary to bring about transformation in the absence of other factors, though a recent article suggests that they may appear as a result of coronary spasm in the absence of total occlusion (see below).This information is cited for the record only. Within ninety seconds of occlusion, the pressure gradient between the segment of the coronary vessel distal to the occlusion and the incipient collateral vessel precipitates damage to the internal elastic lamina, provoking an inflammatory response; monocytes and polycytes migrate to the vascular wall, which has, as a result of the occlusion, become permeable to the blood's cellular components.Freedman SB, et al., "Influence of coronary collateral blood flow on the development of exertional ischemia and Q wave infarction in patients with severe single-vessel disease," Circulation 1985; 71 (4): 681-6.

|
Screen space ambient occlusion (SSAO) is a computer graphics technique for efficiently approximating the ambient occlusion effect in real time. It was developed by Vladimir Kajalin while working at Crytek and was used for the first time in 2007 by the video game Crysis, also developed by Crytek.
|
|
Treatments include artificial tears, prescription tears, and punctal occlusion. Punctal occlusion is accomplished by placing a collagen or silicone plug in the tear duct, which normally drains fluid from the eye. Some patients complain of ongoing dry-eye symptoms despite such treatments and dry-eye symptoms may be permanent.
|
|
A malocclusion is a misalignment or incorrect relation between the teeth of the two dental arches when they approach each other as the jaws close. The term was coined by Edward Angle, the "father of modern orthodontics", as a derivative of occlusion. This refers to the manner in which opposing teeth meet (mal- + occlusion = "incorrect occlusion"). The malocclusion classification is based on the relationship of the Mesiobuccal cusp of the maxillary first molar and the buccal groove of the mandibular first molar.

|
Alternating occlusion training, also referred to as electronic rapid alternate occlusion, is an approach to amblyopia and to intermittent central suppression in vision therapy, in which electronic devices such as programmable shutter glasses or goggles are used to block the field of view of one eye in rapid alternation. When performing alternating occlusion training, the person wears the occlusion goggles continuously for several hours while performing regular everyday activities. Wearing the device encourages or forces the alternating use of both eyes, similar to eye patching, but rapidly alternating in time. The aim is to circumvent the tendency to suppress the field of view of the weaker eye and to train the capacity for binocular vision.

Acute occlusion of the axillary artery resulting in an ischemic limb as seen on CT angiography In order to treat acute limb ischaemia there are a series of things that can be done to determine where the occlusion is located, the severity, and what the cause was. To find out where the occlusion is located one of the things that can be done is simply a pulse examination to see where the heart rate can be detected and where it stops being sensed. Also there is a lower body temperature below the occlusion as well as paleness. A Doppler evaluation is used to show the extent and severity of the ischaemia by showing flow in smaller arteries.

Boland, however, did not live to see his party divide, dying in 1956 at Tingalpa of a coronary occlusion.
|
|
It can also account for the absence of model parts due to appearance variability, occlusion, clutter, or detector error.
|
|
However, it is a very crude approximation to full global illumination. The appearance achieved by ambient occlusion alone is similar to the way an object might appear on an overcast day. The first method that allowed simulating ambient occlusion in real time was developed by the research and development department of Crytek (CryEngine 2). With the release of hardware capable of real time ray tracing (GeForce 20 series) by Nvidia in 2018, ray traced ambient occlusion (RTAO) became possible in games and other real time applications.
|
|
There are various factors that play a role in the adaptive capability of a patient with regards to changes in occlusion. Factors such as the central nervous system and the mechanoreceptors in the periodontium, mucosa and dentition are all of importance here. It is in fact, the somatosensory input from these sources that determines whether an individual is able to adapt to changes in the occlusion, opposed to the occlusal scheme itself. Failure of adaptation to minor changes in the occlusion can occur, although rare.
|
|
Collectively, they carry the vast majority of the blood. Occlusion of a deep vein can be life-threatening and is most often caused by thrombosis. Occlusion of a deep vein by thrombosis is called deep vein thrombosis. Because of their location deep within the body, operation on these veins can be difficult.

|
A major disadvantage of classifying malocclusions according to Angle's system is that it only takes into consideration the two- dimensional viewing along a spatial axis in the sagittal plane in the terminal occlusion, even though occlusion problems are, in principle, three- dimensional. Deviations in other spatial axes, asymmetric deviations, functional faults and other therapy-related features are not recognised. Another shortcoming is the lack of a theoretical basis of this purely descriptive classification system. Among the much discussed weaknesses of the system is the fact that it only considers the static occlusion, that it does not take into account the development and causes (aetiology) of occlusion problems and it disregards the proportions (or relationships in general) of teeth and face.

Many practitioners use The Occlusion Cuff as well as BFR protocols based on published scientific literature. The current approaches that focus on applying BFR during exercise consist of automatic pneumatic tourniquet systems, handheld inflatable device or automatic inflatable devices, called The Occlusion Cuff. Research demonstrating the influence of thigh circumference and cuff width on occlusion pressure has accentuated a likely need for an individualised approach to BFR, particularly with regard to the setting of the restriction pressure. More recently, a technique to calculate and prescribe the occlusive stimulus as a percentage of total limb occlusion pressure is just one example of efforts to account for the above factors and provide an individualised approach to prescribing BFR training that is relatively quick and inexpensive.

In a warm occlusion, the air mass overtaking the warm front is warmer than the cold air ahead of the warm front and rides over the colder air mass while lifting the warm air. A wide variety of weather can be found along an occluded front, with thunderstorms possible, but usually their passage is associated with a drying of the air mass. Within the occlusion of the front, a circulation of air brings warm air upward and sends drafts of cold air downward, or vice versa depending on the occlusion the front is experiencing. Precipitations and clouds are associated with the trowal, the projection on the Earth's surface of the tongue of warm air aloft formed during the occlusion process of the depression.
|
|
Once the cause of tooth wear has been identified and a preventative regime has been put in place, the patient should be reviewed for 6–12 months to establish that the intervention has been successful before any active management is carried out. Once this has been achieved a decision needs to be made whether or not it is necessary to carry out restorative treatment or if it can simply be managed by non invasive methods. Where restorative treatment is necessary, it must be decided whether to conform to the existing occlusion (typically for moderate wear, where only a few teeth are affected) or reorganise the occlusion (severe wear, unstable occlusion). Where the occlusion is reorganised this can first be tested using reversible method i.e.

In the case of non-thrombotic occlusion (e.g. formation of precipitates), dilute acid can be used to restore patency to the catheter. A solution of 0.1N hydrochloric acid is commonly used. Infusates that contain a significant amount of lipids such as total parenteral nutrition (TPN) or propofol are also prone to occlusion over time.

In computer graphics, relief mapping is a texture mapping technique used to render the surface details of three-dimensional objects accurately and efficiently. It can produce accurate depictions of self-occlusion, self- shadowing, and parallax. It is a form of short-distance raytrace done in a pixel shader. Relief mapping is highly comparable in both function and approach to another displacement texture mapping technique, Parallax occlusion mapping, considering that they both rely on raytraces, though the two are not to be confused with each other, as parallax occlusion mapping uses reverse heightmap tracing.

The ex utero intrapartum treatment (EXIT) procedure was originally developed to reverse temporary tracheal occlusion in patients who had undergone fetal surgery for severe congenital diaphragmatic hernia (CDH). In a select group of fetuses with CDH, tracheal occlusion is used to obstruct the normal flow of fetal lung fluid and to stimulate lung expansion and growth. With the airway obstructed, airway management at birth is critical. The solution was to arrange delivery in such a way that the occlusion could be removed and the airway secured while the baby remained on placental support.

A coronary occlusion is the partial or complete obstruction of blood flow in a coronary artery. This condition may cause a heart attack. In some patients coronary occlusion causes only mild pain, tightness or vague discomfort which may be ignored; however, the myocardium, the muscle tissue of the heart, may be damaged. According to Robert K. Massie's Nicholas and Alexandra: The Fall of the Romanov Dynasty, Tsar Nicholas II may have suffered a coronary occlusion right before he was toppled from his throne during the Russian Revolution in 1917.

Reported results of the use of alternating occlusion devices include improved vision, as well as occasional side effects of headaches or discomfort. The purchase of such an electronic LCD may require written permission by the patient's optometrist.Electronic Rapid Alternate Occlusion Goggles , Optometric Extension Program Foundation (OEPF), downloaded 20 August 2013 It was found that the flicker rates of 9 to 11 Hz that were employed in the TBIS device are slow enough and the stimulus weak enough to avoid any risk of epileptic seizure. In principle alternating occlusion may interfere with normal visual input.

Also by avoiding prolonged compression of the radial artery and applying just enough pressure to achieve hemostasis reduces this complication of asymptomatic radial occlusion significantly. Implying this approaches the radial artery occlusion rate has come down to 1.1-1.8%.Pancholy S, Coppola J, Patel T, Roke-Thomas M.

Intercuspal position (ICP), also known as centric occlusion, is a position in which teeth occlusion plays an important role. In the majority of population, centric occlusion is said to be averagely 1 mm anterior to centric relation in the natural dentition. Intermediate zone of the articular disk lies in between condyle and eminence posterior slope, with posterior band lying above condyle. Retruded Centric Position or the other term called Centric Relation is when the condyles are located in the uppermost position in mandibular fossa, anterior to distal slope of articular eminence.

The ambient occlusion map (middle image) for this scene darkens only the innermost angles of corners. In 3D computer graphics, modeling, and animation, ambient occlusion is a shading and rendering technique used to calculate how exposed each point in a scene is to ambient lighting. For example, the interior of a tube is typically more occluded (and hence darker) than the exposed outer surfaces, and becomes darker the deeper inside the tube one goes. Ambient occlusion can be seen as an accessibility value that is calculated for each surface point.

The increased pressure results in thrombosis and occlusion of the small vessels, and stasis of lymphatic flow. At this point, spontaneous recovery rarely occurs. As the occlusion of blood vessels progresses, the appendix becomes ischemic and then necrotic. As bacteria begin to leak out through the dying walls, pus forms within and around the appendix (suppuration).

Potentially Visible Sets are used to accelerate the rendering of 3D environments. This is a form of occlusion culling, whereby a candidate set of potentially visible polygons are pre-computed, then indexed at run-time in order to quickly obtain an estimate of the visible geometry. The term PVS is sometimes used to refer to any occlusion culling algorithm (since in effect, this is what all occlusion algorithms compute), although in almost all the literature, it is used to refer specifically to occlusion culling algorithms that pre-compute visible sets and associate these sets with regions in space. In order to make this association, the camera view-space (the set of points from which the camera can render an image) is typically subdivided into (usually convex) regions and a PVS is computed for each region.

It is a widespread habit among eye specialists (ophthalmologists) to prescribe aspirin as an add-on medication for patients with retinal vein occlusion (RVO), such as central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO). The reason of this widespread use is the evidence of its proven effectiveness in major systemic venous thrombotic disorders, and it has been assumed that may be similarly beneficial in various types of retinal vein occlusion. However, a large-scale investigation based on data of nearly 700 patients showed "that aspirin or other antiplatelet aggregating agents or anticoagulants adversely influence the visual outcome in patients with CRVO and hemi-CRVO, without any evidence of protective or beneficial effect". Several expert groups, including the Royal College of Ophthalmologists, recommended against the use of antithrombotic drugs (incl.

Occlusion, in a dental context, means simply the contact between teeth. More technically, it is the relationship between the maxillary (upper) and mandibular (lower) teeth when they approach each other, as occurs during chewing or at rest. Static occlusion refers to contact between teeth when the jaw is closed and stationary, while dynamic occlusion refers to occlusal contacts made when the jaw is moving. The masticatory system also involves the periodontium, the TMJ (and other skeletal components) and the neuromusculature, therefore the tooth contacts should not be looked at in isolation, but in relation to the overall masticatory system..

Technical difficulties are because of loops and tortuosity of the radial and the subclavian artery, anatomical variations in radial artery, and radial spasm. Major complication associated with a transradial interventions include early and late radial artery occlusion. Most of the radial artery occlusions are asymptomatic. Post PCI radial artery occlusion can be reduced by using smaller diameter catheters and anticoagulation.

|
'Linear occlusal concept' was introduced by Frush in 1967. In this, the mesiodistal ridge of the lower posterior teeth contacted the upper posterior teeth with flat occlusal surface in order to achieve balanced occlusion. He relied on the intraoral corrections to obtain balanced occlusion. Again, his main goal was to eliminate deflective occlusal contacts and therefore increase stability of the prostheses.

The Dahl concept is the relative axial tooth movement that is observed when a localised appliance or localised restorations are placed in supra-occlusion and the occlusion re-establishes full arch contacts over a period of time.Poyser, Neil & W J Porter, R & F A Briggs, P & S Chana, H & Kelleher, Martin. (2005). The Dahl concept: Past, present and future. British dental journal. 198.

669-76; quiz 720. 10.1038/sj.bdj.4812371. It involves the vertical tooth movement that occurs when anterior localised appliances/restorations are placed in supra occlusion causing the posterior teeth to disclude. Rather than restoring occlusion by means of restoration, it is allowed to re-establish over time through a combination of intrusion and over-eruption. This, in turn, will increase the OVD.

Binasal occlusion is a method of partial covering (occlusion) of the visual field of the two eyes in which the sector of the visual field that is adjacent to the nose (the nasal visual field) is occluded for each eye. It is a well- known procedure in vision therapy. By blocking parts of the image that would be seen by both eyes, binocular occlusion reduces the visual stress that would be related diplopia and binocular rivalry. In contrast to an eye patch that occludes the whole visual field of one eye, binocular occlusion allows some degree of binocular vision; more particularly, it emphasizes the role of binocular functioning in peripheral vision: objects that are located to the right can only be fixated by the right eye, and those located to the left only by the left eye.

Patients with branch retinal vein occlusion usually have a sudden onset of blurred vision or a central visual field defect. The eye examination findings of acute branch retinal vein occlusion include superficial hemorrhages, retinal edema, and often cotton- wool spots in a sector of retina drained by the affected vein. The obstructed vein is dilated and tortuous. The quadrant most commonly affected is the superotemporal (63%).
|
|
If this molar relationship exists, then the teeth can align into normal occlusion. According to Angle, malocclusion is any deviation of the occlusion from the ideal. However the assessment for malocclusion should also take into account aesthetics and the impact on functionality. If these are aspects are acceptable to the patient despite meeting the formal definition of malocclusion, then treatment may not be necessary.

The technique of modeling ischemic stroke by transient transcranial MCAO is similar to that of permanent transcranial MCAO, with the MCA being reperfused after a defined period of focal cerebral ischemia . Like permanent MCAO, craniotomy is required and common carotid artery (CCA) occlusion can be combined. Occluding one MCA and both CCAs is referred to as the three vessel occlusion model of focal cerebral ischemia.

This may localize all the force of the bite onto one tooth, and cause inflammation of the periodontal ligament and reversible increase in tooth mobility. The tooth may become tender to bite on. Here, the "occlusal adjustment" has already taken place inadvertently, and the adjustment aims to return to the pre-existing occlusion. This should be distinguished from attempts to deliberately reorganize the native occlusion.

Patients and dentists both have a mutualistic, indispensable role in the construction of a fully functional denture, which include elements such as adequate retention, stability, extensions and aesthetic appearance. Apart from the balanced occlusion schemes as described above, other approaches for obtaining functional occlusion in complete dentures have been proposed. The concept of "Non-Balanced Occlusion" was based on the difficulty of achieving this, not only in the prosthetics laboratory, but for patients with displaceable mucosae. Then there is the much-quoted truism first cited by Boucher "Enter Bolus, Exit Balance"; whenever the patient masticates food on their working side, it negates the balance on the opposing side.

Natural cosmetic companies claim that the use of mineral oil results in skin occlusion. Conventional cosmetic manufacturers and even dermatologists and cosmetic chemists argue against that and studies were not able to show any statistical difference between paraffin oil and vegetable oils in terms of skin penetration and skin occlusion. On the contrary, petrolatum-based preparations have been shown to be effective to the skin barrier function, even in premature infants.

In general, branch retinal vein occlusion has a good prognosis: after 1 year 50–60% of eyes have been reported to have a final visual acuity of 20/40 or better even without any treatment. With time the dramatic picture of an acute branch retinal vein occlusion becomes more subtle, hemorrhages fade so that the retina can look almost normal. Collateral vessels develop to help drain the affected area.

The uterus opens into the Fallopian tube at the proximal tubal opening (also called the proximal ostium or os), after the uterotubal junction, and accessible via hysteroscopy. Occlusion at this opening is referred to as proximal tubal occlusion. From there there are three named parts of the Fallopian tube; the isthmus, the ampulla, and the infundibulum. The isthmus sits next to the opening of the Fallopian tube into the uterus.
|
|
The PCAs arise directly from the OA and are end arteries which is to say no PCA or any of its branches anastomose with any other artery. Consequently, sudden occlusion of any PCA will produce an infarct in the region of the choroid supplied by that particular PCA. Occlusion of a short or long PCA will produce a smaller choroidal infarct, within the larger area supplied by the specific parent PCA.

Staged manual compression of the ipsilateral carotid has been reported to assist with spontaneous closure in selected cases. Direct CCF may be treated by occlusion of the affected cavernous sinus (coils, balloon, liquid agents), or by reconstruction of the damaged internal carotid artery (stent, coils or liquid agents). Indirect CCF may be treated by occlusion of the affected cavernous sinus with coils, liquid agents or a combination of both.

However, it has been shown that CPO has better patient preference for dental aesthetics compared with bilateral balanced occlusion. Also, it has been argued that CPO reduces destructive lateral forces on the alveolar bone by promoting vertical chewing. As stated above, it has been reported that fabrication of dentures using cuspid protection occlusal scheme both realizable and less time consuming compared to constructing dentures with bilateral balanced occlusion.

A heart attack occurs when an occlusion (e.g. blood clot) of an artery in the heart slowly causes tissue to die. This can result in chest pain and discomfort, and requires immediate medical attention to resolve the occlusion by emergency surgery or cardiac clot-busting drugs. A cardiac dysrhythmia is primarily an electrical problem within the heart, and is sometimes treated with electrolytes, vagal maneuver, or electrical cardioversion.

The flicker rates at which the occlusion is alternated between the two eyes in alternating occlusion training are generally much slower than those employed by the widespread active shutter 3D glasses for viewing 3D television or cinema. Therapeutic procedures have been proposed in which the active eye is switched after a duration of many seconds (for example, with an ON (occlusion) duration of 40 seconds and an OFF state (open) duration of 20 seconds of each minute); others propose a much faster flicker rate of approximately 5 Hz. (abstract, full text PDF) An alternating occlusion device (the so-called Translid Binocular Interaction Trainer (TBIS) operating at a rate of 9 to 11 Hz) was introduced by Merrill Allen in 1967 to favor parallel processing of the eyes.Merrill J.

An arterial embolism is caused by one or more emboli getting stuck in an artery and blocking blood flow, causing ischemia, possibly resulting in infarction with tissue death (necrosis). Individuals with arterial thrombosis or embolism often develop collateral circulation to compensate for the loss of arterial flow. However, it takes time for sufficient collateral circulation to develop, making affected areas more vulnerable for sudden occlusion by embolisation than for e.g. gradual occlusion as in atherosclerosis.

Collateral tortuous vein (center, left) in central retinal vein occlusion, revealed by laser Doppler imaging. After central retinal vein occlusion, neovascularization may restore some blood flow to the retina, but the new vessels' bulk also presents a risk of causing acute glaucoma by blocking the drainage of aqueous humour. Collateral circulation is created (within months) around the blocked central vein via a generally winding path, usually from a branch vein to the choroid.

After preliminary work by Daniel Evans (1840) and as a result of his jaw measurements Bonwill developed in 1864 the first Bonwill articulator, a device for simulating the temporomandibular joint movements for manufacturing dentures. These plaster models of the dental arches of the upper and lower jaw are mounted in occlusion in the articulator. Bonwill coined the term articulation and replaced the older concept of occlusion. Its principle was used in almost all advanced articulators.

It is unlikely the TMJ will adapt to these changes in occlusion, but rather the teeth adapt to the new occlusion through tooth wear, tooth movement or fracture. For this reason, it is important to consider these guidance concepts when providing restorations. Guidance should also be considered before restorations as it should not be expected for a heavily restored tooth to provide guidance alone as this leaves the tooth vulnerable to fracture during function.

Chris Green of Valve, a video game maker, says that bump map data is derived from geometric descriptions of the objects surface significant lighting cues due to lighting occlusion by surface details are not calculated. A common fix is to use an additional texture channel to create an ambient occlusion field. This only provides a darkening effect that is not connected to the direction of the light source on acting on the surface.

When an individual loses enough posterior teeth to make it difficult to chew, he or she may need to cut their food into very small pieces and learn how to make use of their anterior teeth to chew. If enough posterior teeth are missing, this will not only affect their chewing abilities, but also their occlusion; posterior teeth, in a mutually protected occlusion, help to protect the anterior teeth and the vertical dimension of occlusion and, when missing, the anterior teeth begin to bear a greater amount of force for which they are structurally prepared. Thus, loss of posterior teeth will cause the anterior teeth to splay. This can be prevented by obtaining dental prostheses, such as removable partial dentures, bridges or implant-supported crowns.
|
|
Dentofacial and functional malocclusions can also affect normal speech. Non-physiologic function of the tongue has been considered an important aetiological factor of malocclusions. The tongue is an important organ contributing to deglutition, speech, growth and development of the jaws, and alignment of the teeth in occlusion. The effect of the tongue on growth of the jaws and development of the occlusion is a result of its pressure on the teeth and other areas during rest and function.

It connects to the ampulla (), which curves over the ovary and is the most common site of human fertilization. The ampulla connects with the infundibulum, which rests above the ovaries, and ends at the distal tubal opening (or abdominal ostium) into the abdominal cavity where, in ovulation, the oocyte enters the Fallopian tube. The opening is surrounded by fimbriae, which help in the collection of the oocyte. Occlusion of this opening is referred to as distal tubal occlusion.

Hemorrhagic infarcts are infarcts commonly caused by occlusion of veins, with red blood cells entering the area of the infarct, or an artery occlusion of an organ with collaterals or dual circulation. This is commonly seen in brain, lungs, and the GI tract, areas referred to as having "loose tissue," or dual circulation. Loose-textured tissue allows red blood cells released from damaged vessels to diffuse through the necrotic tissue. White infarcts can become hemorrhagic with reperfusion.

As with all max anterior teeth, the central incisors are usually located facially to the mandibular teeth when the mouth is closed. In instances when the maxillary anterior teeth are lingual to the mandibular teeth, the condition is referred to as an anterior crossbite. In some cases, this arrangement of teeth may indicate a displacement of the mandible relative to the maxilla and is called Class III or Pseudo-Class III malocclusion. Normal occlusion is Class I occlusion.
|
|
The path of the condyle is determined by the temporal bone and that cannot be changed. However, records can be altered on the articulator or when transferring occlusal records from the patient's mouth to the articulator. Subsequently, it is difficult to state that condylar guidance is constant, and this may affect the statement that it is the only fixed factor in establishing balanced occlusion. In conclusion, an ideal occlusion is set by various groups based on a hypothetical assumption.

Canine guidance occlusion/mutually protected/ cuspid protection is a concept that was introduced by Nagao in 1919. It is defined as the contact of maxillary cuspids with the lower cuspids or premolars on all eccentric movements. Support of the Cuspid Protected Occlusion (CPO) was made by early studies that showed predominance of innate CPO in mammals. They also argued that the canine tooth possessed enhanced proprioception, thereby 'protecting' unfavourable forces on other teeth in the dentition.

|
The major cause for distal tubal occlusion is pelvic inflammatory disease (PID), usually as a consequence of an ascending infection by chlamydia or gonorrhea. However, not all pelvic infections will cause distal tubal occlusion. Tubal tuberculosis is an uncommon cause of hydrosalpinx formation. While the cilia of the inner lining (endosalpinx) of the fallopian tube beat towards the uterus, tubal fluid is normally discharged via the fimbriated end into the peritoneal cavity from where it is cleared.

However, this would lead to a lack of axial height and thus insufficient retention and resistance for conventional extra-coronal restorations. Tooth preparation and the associated loss of coronal tissue can risk further insult to the pulp and limit the options for future restoration replacement. An alternative approach is to create the necessary space by reorganising the occlusion by means of an arbitrary increase of the vertical dimension of occlusion, i.e. the use of a dahl appliance.

There are generally 12 maxillary teeth. It has been established that Massetognathus with multi-cuspate post canines adapted to herbivory, moved the lower jaw posteriorly and dorsally during the power stroke of the occlusion. Massetognathus is the only cynodont from the Chañares Formation with clear adaptations for herbivory, with basined, labiolingually expanded upper and lower post-canines, ensuring a rudimentary dental occlusion, feeding on ground level vegetation or on the lower branches of taller plants and shrubs.

A dilated left ventricle is generally due to the effects of a myocardial infarction. An occlusion, or blockage, results in either akinetic (non-beating) or dyskinetic (irregular beating) tissue downstream from the occlusion. This tissue is virtually useless. However, the volume of blood that fills the ventricle prior to contraction, or end-diastolic volume, remains constant, so the tissue that still functions has to do more work to eject the blood, as the Frank-Starling Laws demand.

Ischemic enteritis is uncommon compared to ischemic colitis due to the highly vascularised nature of the small intestine, allowing for sufficient blood flow in most situations. It develops due to circulatory shock of mesenteric vessels in the absence of major vessel occlusion, often associated with an underlying condition such as hypertension, arrhythmia or diabetes. Thus it has been considered to be associated with atherosclerosis. Surgical treatment is usually required due to the likelihood of stenosis or complete occlusion of the small intestine.

The tooth attachment mode of some dinosaurs has been referred to as thecodonty. This is a condition where the tooth is deeply implanted into the tooth socket with periodontal ligament present, as is the case in crocodilians and mammals. In mammals, thecodonty is associated with dental occlusion while in crocodilians it has been proposed as a means to reduce stresses from bite forces. Coelophysis possessed neither dental occlusion nor a strong bite, raising questions as to why it possesses thecodonty.

Centre for Disease Control There is also a risk of blood clots.. The use of heparin to maintain a PICC line is not universal, as heparin locks have been associated with complications, including heparin-induced thrombocytopaenia. Other complications may include catheter occlusion, phlebitis and bleeding. Urokinase or low-dose tPA may be required to break down obstructions, depending on the type and severity of the occlusion. A blood pressure reading can not be taken on an arm with a PICC line inserted.

Monoplane occlusion correspondingly requires having anterior teeth with no vertical overlap thus resulting in suboptimal dental aesthetics. However, some studies have suggested that a monoplane occlusion can result in reduced masticatory ability. DeVan rejected the concept of BBO because in function, the stability of the denture is lost. He therefore suggested that function can most satisfactorily be achieved by a neurocentric scheme adopting the following five factors: # Position: the artificial teeth should be placed in a central position in relation to the ridge.

In some languages, such consonants may occur before vowels and are called prestopped nasals. Prestopped nasals and prenasalized stops occur when the oral cavity is closed and the nasal cavity is opened by lowering the velum, but the timing of both events does not coincide. A prenasalized stop starts out with a lowered velum that raises during the occlusion, much like the [nd] in candy. A postnasalized stop or prestopped nasal begins with a raised velum that lowers during the occlusion.
|
|
In phonetics, a plosive, also known as an occlusive or simply a stop, is a pulmonic consonant in which the vocal tract is blocked so that all airflow ceases. The occlusion may be made with the tongue tip or blade (, ) tongue body (, ), lips (, ), or glottis (). Plosives contrast with nasals, where the vocal tract is blocked but airflow continues through the nose, as in and , and with fricatives, where partial occlusion impedes but does not block airflow in the vocal tract.
|
|
Simple nasals are differentiated from plosives only by a lowered velum that allows the air to escape through the nose during the occlusion. Nasals are acoustically sonorants, as they have a non-turbulent airflow and are nearly always voiced, but they are articulatorily obstruents, as there is complete blockage of the oral cavity. The term occlusive may be used as a cover term for both nasals and plosives. A prenasalized stop starts out with a lowered velum that raises during the occlusion.

Arterial dissection of the carotid arteries occurs when a small tear forms in the innermost lining of the arterial wall (known as the tunica intima). Blood is then able to enter the space between the inner and outer layers of the vessel, causing narrowing (stenosis) or complete occlusion. The stenosis that occurs in the early stages of arterial dissection is a dynamic process and some occlusions can return to stenosis very quickly. When complete occlusion occurs, it may lead to ischaemia.

The ophthalmic artery branches off into the central retinal artery which travels with the optic nerve until it enters the eye. This central retinal artery provides nutrients to the retina of the eye, more specifically the inner retina and the surface of the optic nerve. Variations, such as branch retinal artery occlusion, can also occur. Central retinal artery occlusion is most often due to emboli blocking the artery and therefore prevents the artery from delivering nutrients to most of the retina.

Iguanodontids are low-browsing herbivores that fed extensively on gymnosperms like ferns and horsetails, especially during the early Cretaceous period. These dinosaurs were very effective as herbivores due in part to their combination of bilateral dental occlusion with the transverse power stroke of their chewing mechanism. Additionally, iguanodontids lack a rigid secondary palate, which helps to mitigate torsional stresses during occlusion, a feature that enhanced their ability to break down plant matter. Additionally, the iguanodontids co-evolved with the radiation of angiosperms in the Cretaceous period.

A physical examination of the hand may show discoloration (blanching, mottling, and/ or cyanosis; gangrene may be present in advanced cases), unusual tenderness/ a callous over the hypothenar eminence, and fingertip ulcerations and splinter hemorrhages over ulnar digits; if an aneurysm is present, there may also be a pulsatile mass. Allen's test will be positive if an occlusion is present and negative if an aneurysm is present. An angiogram may show a "corkscrew" ulnar artery or an occlusion or aneurysm at the hook of the hamate.

Homonymous hemianopsia secondary to posterior cerebral artery occlusion - may result in syndromes of memory impairment, opposite visual field loss (homonymous hemianopsia), and sometimes hemisensory deficits. The PCA supplies the occipital lobe and the medial portion of the temporal lobe. Infarction of occipital cortex typically causes macular sparing hemianopias due to dual blood supply from both posterior cerebral artery and middle cerebral artery. Occlusion of the calcarine artery that results in infarction of the superior part of the occipital lobe causes a lower peripheral visual field defect.

This arrangement of teeth is tested in the mouth so that adjustments can be made to the occlusion. After the occlusion has been verified by the dentist or denturist and the patient, and all phonetic requirements are met, the denture is processed. Processing a denture is usually performed using a lost-wax technique whereby the form of the final denture, including the acrylic denture teeth, is invested in stone. This investment is then heated, and when it melts the wax is removed through a spruing channel.

Central retinal vein occlusion, also CRVO, is when the central retinal vein becomes occluded, usually through thrombosis. The central retinal vein is the venous equivalent of the central retinal artery and both may become occluded.Ophthalmology at a Glance, Jane Olver & Lorraine Cassidy, Blackwell Science 2005. Since the central retinal artery and vein are the sole source of blood supply and drainage for the retina, such occlusion can lead to severe damage to the retina and blindness, due to ischemia (restriction in blood supply) and edema (swelling).
|
|
If adequate recovery has not occurred after the 6 month period (during which observation, prism management, occlusion, or botulinum toxin may be considered), surgical treatment is often recommended. If the residual esotropia is small, or if the patient is unfit or unwilling to have surgery, prisms can be incorporated into their glasses to provide more permanent symptom relief. When the deviation is too large for prismatic correction to be effective, permanent occlusion may be the only option for those unfit or unwilling to have surgery.

Tweed occlusion refers to an end result of an orthodontic treatment that Tweed and his followers tried to achieve when finishing treatment. He believed in maximum facial harmony and balance, defined as the lower midface being more retruded than the upper, and therefore he believed in treating the mandibular incisors over the basal bone of the mandible. Components of tweed occlusion are: # Flat mandibular arch # Maintaining the Curve of Spee in Maxillary Arch # Second molars in both arches tipped distally and out of occlusion with each other # First molars tipped distally so Mesiobuccal Cusp of Upper 1st molar lying on the buccal groove of the lower 1st molar # Anterior teeth close to an end-to-end relationship. He believed in maximum facial harmony and balance and therefore he believed in treating the mandibular incisors over the basal bone of the mandible.

The underlying pathophysiology of frostbite is a combination of freezing, vascular insufficiency (constriction and occlusion) and damage due to inflammatory mediators. As extremities cool, the ‘hunting response of Lewis’ (alternating vasoconstriction and vasodilation) occurs, ending with vasoconstriction.

Nitrous oxide at 75% by volume reduces ischemia-induced neuronal death induced by occlusion of the middle cerebral artery in rodents, and decreases NMDA-induced Ca2+ influx in neuronal cell cultures, a critical event involved in excitotoxicity.

|
Damage, due to trauma or spontaneously, may lead to hemorrhage due to mechanical damage to the vessel endothelium. In contrast, occlusion of the blood vessel by atherosclerotic plaque, by an embolised blood clot or a foreign body leads to downstream ischemia (insufficient blood supply) and possibly necrosis. Vessel occlusion tends to be a positive feedback system; an occluded vessel creates eddies in the normally laminar flow or plug flow blood currents. These eddies create abnormal fluid velocity gradients which push blood elements such as cholesterol or chylomicron bodies to the endothelium.

Occlusion refers to the closing of the dinosaur's mouth, where the teeth from the upper and lower parts of the jaw meet. If the occlusion causes teeth from the maxillary or premaxillary bones to cover the teeth of the dentary and predentary, the dinosaur is said to have an overbite, the most common condition in this group. The opposite condition is considered to be an underbite, which is rare in theropod dinosaurs. The majority of dinosaurs had teeth that were similarly shaped throughout their jaws but varied in size.
|
|
One major variable that these concepts did not consider is the patient's neuromuscular adaptation for their new denture. Another point worthy of note is that the angle of the condyle in medial direction which also affects the direction of force. It is easy to establish the balanced occlusion on an articulator, but other variables come into play the moment the denture is inside the patient's mouth and this further affects the outcome of treatment. The assumption that articulator movement is similar to mandibular movement formed the basis of balanced occlusion schemes.

290x290px Intercuspal Position (ICP), also known as Habitual Bite, Habitual Position or Bite of Convenience , is defined at the position where the maxillary and mandibular teeth fit together in maximum interdigitation. This position is usually the most easily recorded and is almost always the occlusion the patient closes into when they are asked to 'bite together'. This is the occlusion that the patient is accustomed to, hence sometimes termed the Habitual Bite. Centric relation (CR) describes a reproducible jaw relationship (between the mandible and maxilla) and is independent of tooth contact.

Binocular cues include retinal disparity, which exploits parallax and vergence. Stereopsis is made possible with binocular vision. Monocular cues include relative size (distant objects subtend smaller visual angles than near objects), texture gradient, occlusion, linear perspective, contrast differences, and motion parallax.

Parallax mapping is implemented by displacing the texture coordinates at a point on the rendered polygon by a function of the view angle in tangent space (the angle relative to the surface normal) and the value of the height map at that point. At steeper view-angles, the texture coordinates are displaced more, giving the illusion of depth due to parallax effects as the view changes. Parallax mapping described by Kaneko is a single step process that does not account for occlusion. Subsequent enhancements have been made to the algorithm incorporating iterative approaches to allow for occlusion and accurate silhouette rendering.

Topical atropine is used as a cycloplegic, to temporarily paralyze the accommodation reflex, and as a mydriatic, to dilate the pupils. Atropine degrades slowly, typically wearing off in 7 to 14 days, so it is generally used as a therapeutic mydriatic, whereas tropicamide (a shorter-acting cholinergic antagonist) or phenylephrine (an α-adrenergic agonist) is preferred as an aid to ophthalmic examination. In refractive and accommodative amblyopia, when occlusion is not appropriate sometimes atropine is given to induce blur in the good eye. Evidence suggests that atropine penalization is just as effective as occlusion in improving visual acuity.

Arthropods evolved herbivory in four phases, changing their approach to it in response to changing plant communities. Tetrapod herbivores made their first appearance in the fossil record of their jaws near the Permio-Carboniferous boundary, approximately 300 million years ago. The earliest evidence of their herbivory has been attributed to dental occlusion, the process in which teeth from the upper jaw come in contact with teeth in the lower jaw is present. The evolution of dental occlusion led to a drastic increase in plant food processing and provides evidence about feeding strategies based on tooth wear patterns.

Occluded front depiction for the Northern Hemisphere An occluded front is formed when a cold front overtakes a warm front, and usually forms around mature low-pressure areas. The cold and warm fronts curve naturally poleward into the point of occlusion, which is also known as the triple point. It lies within a sharp trough, but the air mass behind the boundary can be either warm or cold. In a cold occlusion, the air mass overtaking the warm front is cooler than the cool air ahead of the warm front and plows under both air masses.

|
However, there may be potential for the NTI-TSS device to act as a Dahl appliance, holding the posterior teeth out of occlusion and leading to their over-eruption, deranging the occlusion (i.e. it may cause the teeth to move position). This is far more likely if the appliance is worn for excessive periods of time, which is why NTI type appliances are designed for night time use only, and ongoing follow-ups are recommended. A mandibular advancement device (normally used for treatment of obstructive sleep apnea) may reduce sleep bruxism, although its use may be associated with discomfort.
|
|
It is common practice to mount mandibular and maxillary casts (impressions are made of the teeth and poured in dental stone) in an articulator in ICP when constructing restorations that conform to the patient's existing occlusion. Casts mounted on an articulator in ICP are useful for diagnostic purposes or simple restorations, but where more extensive treatment is planned it is necessary to consider occlusal contacts relative to CR e.g. RCP -> ICP slide. Other situations a CR registration may be more appropriate than ICP include where there are plans to reorganise or adjust the existing occlusion (including changes to the occlusal vertical dimension).

The resulting sounds () are called pre-stopped consonants, or sometimes pre-ploded or (in Celtic linguistics) pre-occluded consonants, although technically may be considered an occlusive/stop without the pre- occlusion. A pre-stopped consonant behaves phonologically as a single consonant. That is, like affricates and trilled affricates, the reasons for considering these sequences to be single consonants lies primarily in their behavior.

Abnormal swallowing patterns push the upper teeth forward and away from the upper alveolar processes and cause open bites. In children, tongue thrusting is common due to immature oral behavior, narrow dental arch, prolonged upper respiratory tract infections, spaces between the teeth (diastema), muscle weakness, malocclusion, abnormal sucking habits, and open mouth posture due to structural abnormalities of genetic origin. Large tonsils and adenoids also contribute to tongue thrust swallowing. From the dental perspective, teeth move in relation to the balance of the soft tissue; the normal relationship of teeth lies in occlusion; and any deviation from the normal occlusion can lead to dental distress.

Middle cerebral artery (MCA) occlusion is achieved in this model by injecting particles like blood clots (thrombembolic MCAO) or artificial spheres into the carotid artery of animals as an animal model of ischemic stroke. Thrombembolic MCAO is achieved either by injecting clots that were formed in vitro or by endovascular instillation of thrombin for in situ clotting . The thrombembolic model is closest to the pathophysiology of human cardioembolic stroke. When injecting spheres into the cerebral circulation, their size determines the pattern of brain infarction: Macrospheres (300–400 µm) induce infarcts similar to those achieved by occlusion of the proximal MCA , whereas microsphere (~ 50 µm) injection results in distal, diffuse embolism .

Another study of 2013 suggests that playing a version of the popular game Tetris that is modified such that each eye sees separate components of the game may also help to treat this condition in adults. Furthermore, the effects of this kind of therapy may be further enhanced by noninvasive brain stimulation as shown by a recent study using anodal tDCS. A 2014 Cochrane review sought to determine the effectiveness of occlusion treatment on patients with sensory deprivation amblyopia, but no trials were found eligible to be included in the review. However, good outcomes from occlusion treatment for sensory deprivation amblyopia likely rely on compliance with the treatment.

He argued that tongue function is paramount in achieving denture stabilisation; # Proportion: By reducing the bucco-lingual dimension by 40%; # Pitch: Compensating curves should not be employed, and the denture plane should be parallel to the denture base; # Form: The use of cuspless teeth; #Number of teeth: The number of denture teeth should be reduced from 8 to 6 posterior teeth. Monoplane occlusion correspondingly requires having anterior teeth with no vertical overlap thus resulting in suboptimal dental aesthetics. However, some studies have suggested that a monoplane occlusion can result in reduced masticatory ability. DeVan argued that this occlusal scheme resulted in preservation of the alveolar bone.

Occlusion is defined most simply as "contacts between teeth", and is the meeting of teeth during biting and chewing. The term does not imply any disease. Malocclusion is a medical term referring to less than ideal positioning of the upper teeth relative to the lower teeth, which can occur both when the upper jaw is ideally proportioned to the lower jaw, or where there is a discrepancy between the size of the upper jaw relative to the lower jaw. Malocclusion of some sort is so common that the concept of an "ideal occlusion" is called into question, and it can be considered "normal to be abnormal".

Lacunar stroke or lacunar cerebral infarct (LACI) is the most common type of ischaemic stroke, resulting from the occlusion of small penetrating arteries that provide blood to the brain's deep structures. Patients who present with symptoms of a lacunar stroke, but who have not yet had diagnostic imaging performed, may be described as suffering from lacunar stroke syndrome (LACS). Much of the current knowledge of lacunar strokes comes from C. Miller Fisher's cadaver dissections of post-mortem stroke patients. He observed "lacunae" (empty spaces) in the deep brain structures after occlusion of 200–800 μm penetrating arteries and connected them with five classic syndromes.

It is not certain whether this partial occlusion fully explains the inhibiting effect. The exact mechanism by which Kaliseptine alters KV1.2 function is still debated. Kaliseptine is thought to act in conjunction with other neurotoxins present in the snakelocks anemone venom, altogether prolonging the action potential.

Cardiovascular disease is the leading cause of death in the world. Ischemic heart disease develops when stenosis and occlusion of coronary arteries develops, leading to reduced perfusion of the cardiac tissues. There is ongoing research exploring techniques that might be able to induce healthy neovascularization of ischemic cardiac tissues.

Occlusion of the pontic with the opposing tooth should be assessed. This may determine which type of design is most appropriate and therefore how many abutments are required. For resin bonded bridges the pontic should have light contact in intercuspal position (ICP) and no contact in lateral excursions.

In this animal model of ischemic stroke the middle cerebral artery (MCA) is surgically dissected and subsequently permanently occluded, e.g. by electrocautery or ligation. Occlusion can be performed on the proximal or distal part of the MCA. In the latter, ischemic damage is restricted to the cerebral cortex.

That so many adequately collateralized areas showed no evidence of subsequent improvement in myocardial perfusion also provided evidence that collaterals may often be of little or no significance. However, it is possible that such collaterals appeared too late after infarction to significantly improve overall perfusion. Since Kolibash's study, newer techniques have been used effectively to investigate the issues he raised and to characterize both the mechanism of the transformation of the native collaterals and assess their impact on myocardial perfusion and function—among them percutaneous transluminal coronary angioplasty (PTCA), ergovine-provocative spasm tests, and myocardial perfusion studies. Using PTCA, Rentrop demonstrated that collateral vessel filling jumps dramatically during coronary occlusion by balloon inflation—within ninety seconds of total occlusion.

For multi- listener environments and auditoria, the occlusion of speakers by other listeners must not be under-estimated. Generally, the higher the order and the more physically accurate the reproduction, the more robust it is, up to the point where occlusion produces realistic effects that are consistent with the affected listener's visual perception. For low order systems however, reconstruction can easily fail entirely when line-of-sight to speakers is blocked, which has led to odd seating arrangements in listening tests.Stephen Thornton, Surround sound from two-channel stereo, see photos, retrieved 2014-01-02 With-height systems usually provide more unhindered lines-of-sight per direction for a given audience, which might increase their robustness.

|
If rifamycin binds the polymerase after the chain extension process has started, no inhibition is observed on the biosynthesis, consistent with a steric-occlusion mechanism. Single step high level resistance to the rifamycins occurs as the result of a single amino acid change in the bacterial DNA dependent RNA polymerase.
|
|
All detection methods except inductive loop detectors and magnetometers suffer in accuracy as the result of the concept of occlusion. This limits the cameras view in certain instances. There are different categories of actuated signals. To save money on maintenance, some agencies opt to design an intersection as semi-actuated.

Obstruction of the nasolacrimal duct may occur."Blocked tear ducts in infants" , Pediatric Views, June 2006. This leads to the excess overflow of tears called epiphora (chronic low-grade nasolacrimal duct occlusion). A congenital obstruction can cause cystic expansion of the duct and is called a dacryocystocele or Timo cyst.

It is transmitted orally, when the larvae ingest material contaminated with the virus. The pathogen invades through the gut wall. It reproduces in the internal tissues, causing disintegration of internal organs and death, within 10–14 days. The host ruptures, distributing viral occlusion bodies into the environment to infect other individuals.
|
|
However, a different possible explanation has emerged. Alternatively, the vascular occlusion could be the result of microemboli from the carotid thrombi before the lumen becomes completely blocked. In this scenario, the clotting becomes too severe and the clot breaks free. The resulting traveling clot is known as an embolus (plural emboli).

This is an important jaw position, as it defines both the anterior-posterior and lateral relationships of the mandible and the maxilla, as well as the superior- inferior relationship known as the vertical dimension of occlusion. These are important considerations when evaluating a patient orthodontically, as well as restoring them prosthodontically.

In 21.4% of cases, ischaemic strokes are caused by thrombosis. A thrombus is a blood clot which forms in a cerebral blood vessel, reducing the flow of blood through that vessel. This occlusion of blood vessels causes localised cytotoxic edema which damages the energy-dependent pumps of the cellular membrane causing intracellular inflammation.

To disprove this notion, an experimenter designs an impossible occlusion event. The infant is shown a block and a transparent screen. The infant habituates, then a solid panel is placed in front of the objects to block them from view. When the panel is removed, the block is gone, but the screen remains.

Analyses of light field sampling have been undertaken by many researchers; a good starting point is Chai (2000). Also of interest is Durand (2005) for the effects of occlusion, Ramamoorthi (2006) for the effects of lighting and reflection, and Ng (2005) and Zwicker (2006) for applications to plenoptic cameras and 3D displays, respectively.

Typically one render target holds color and surface information of objects, while another contains the surface normals and depth information of the scene which are used to calculate the reflection of light. Additional render targets can be used to store information such as the specularity of the surface and ambient occlusion data.

In this bilateral balanced occlusal scheme, the posterior teeth are set up at different angles in the coronal plane; 5° for the first premolar teeth, 10° for second premolar teeth, and 15° angle for both the first and second molar teeth. In addition, the occlusal surfaces of mandibular posterior teeth are reduced in a buccal lingual dimension with the aim of improving stability of, particularly the lower prosthesis. Regardless which of the above occlusal schemes are adopted, it is difficult to achieve bilateral balanced occlusion in the prosthetic laboratory. Notwithstanding this, this aspiration of bilateral balanced occlusion is easier to achieve if the 'Buccal Upper Lingual Lower (BU-LL) and Mesial Upper -Distal Lower (MU-DL)' rules are adopted for adjusting cusps.

Testicular sarcoidosis can present as a diffuse painless scrotal mass or can mimic acute epididymo-orchitis. Usually it appears with systemic manifestations of the disease. Since it causes occlusion and fibrosis of the ductus epididymis, fertility may be affected. On ultrasound, the hypoechogenicity and ‘infiltrative’ pattern seen in the present case are recognized features.

The diagnosis of portopulmonary hypertension is based on hemodynamic criteria: #. Portal hypertension and/or liver disease (clinical diagnosis—ascites/varices/splenomegaly) #. Mean pulmonary artery pressure—MPAP > 25 mmHg at rest #. Pulmonary vascular resistance—PVR > 240 dynes s cm−5 #. Pulmonary artery occlusion pressure— PAOP < 15mmHg or transpulmonary gradient—TPG > 12 mmHg where TPG = MPAP − PAOP.

Under extreme pressure, the round ligament may reopen to allow the passage of blood. Such recanalization may be evident in patients with cirrhosis and portal hypertension. Patients with cirrhosis experience rapid growth of scar tissue in and around the liver, often functionally obstructing nearby vessels. Vessel occlusion increases vascular resistance and therefore leads to hypertension.

HME cassettes for tracheotomy patients vary in size and are usually a bit larger than for laryngectomy patients. Air openings are at the side or at the front of the HME. Some designs use crossbars to prevent clothing from blocking. Usually a rim on the lid helps to find the correct finger position for occlusion.

|
A hands-free HME enables laryngectomees to speak without requiring finger occlusion. The device consists of a combination of HME and an automatic speaking valve. The valve closes automatically when exhaling air for speaking, enabling the pulmonary air to be diverted through the voice prosthesis into the esophagus. It reopens automatically when exhalation decreases.

Non-invasive, simple treatments which can be carried out at home should be attempted before in-office procedures are carried out. The purported mechanism of action of these treatments is either occlusion of dentin tubules (e.g. resins, varnishes, toothpastes) or desensitization of nerve fibres/blocking the neural transmission (e.g. potassium chloride, potassium citrate, potassium nitrate).

Patients who had tubal occlusion surgeries have been found to be four to five times more likely to undergo hysterectomy later in life than those whose partners underwent vasectomy. There is no known biologic mechanism to support a causal relationship between tubal ligation and subsequent hysterectomy, but there is an association across all methods of tubal ligation.

Infrared or thermographic cameras are used to facilitate gestural detection. Unlike digital cameras, infrared cameras operate independently of light, instead relying on the heat signature of an object. This is beneficial because it allows for gesture detection in all lighting conditions. However, cameras are subject to occlusion by other objects that may result in a loss of gesture tracking.

The many different types of elastics may produce different forces on teeth. Therefore, using elastics with specific forces is critical in achieving a good orthodontic occlusion. The term intermaxillary elastics is used when elastics can go from the maxillary to the mandibular arch. Intra-maxillary elastics are elastics used in one arch only, either mandibular or maxillary.

Failure of the ETV occurs. This can be due to occlusion of the ventriculostomy (e.g. closure of the ventriculostomy, formation of subarachnoid membranes in the pontine cistern or other mechanisms). Although 60 - 90% of failures occur in the first few months after treatment, long-term failure also occurs (failures occurring after 7 years have been reported).

If carotid occlusive disease results in ophthalmic artery occlusion, general ocular ischemia may result in retinal neovascularization, rubeosis iridis, cells and flare, iris necrosis, and cataract. The condition leads to neovascularization in various eye tissues due to the ischemia. The eye pressure may become high due to associated neovascular glaucoma. An ischemic optic neuropathy may eventually occur.

The inhibitor prevents RNA synthesis by physically blocking elongation, and thus preventing synthesis of host bacterial proteins. By this "steric-occlusion" mechanism, rifampicin blocks synthesis of the second or third phosphodiester bond between the nucleotides in the RNA backbone, preventing elongation of the 5' end of the RNA transcript past more than 2 or 3 nucleotides.

If the uterus was kept relaxed and the utero-placental blood flow kept intact, the fetus could remain on a maternal 'heart-lung machine' while the airway was secured. While the technique of tracheal occlusion remains under study in clinical trials, EXIT procedures have been shown to be useful for management of other causes of fetal airway obstruction.

Occlusion of vascular tissue, while a normal plant response to infection, makes symptoms significantly worse: as the bacterium itself also reduces vascular function, a 90% reduction of vascular hydraulic function was seen in susceptible Vitis vinifera. This bacterium rarely completely blocks vascular tissue. Smaller colonies usually occur throughout a high proportion of xylem vessels of a symptomatic plant.

Background clutter and partial occlusion add difficulties to recognition as well.A. Opelt, A. Pinz, et al., "Generic Object Recognition with Boosting", IEEE Transactions on PAMI 2006 Humans are able to recognize thousands of object types, whereas most of the existing object recognition systems are trained to recognize only a few, e.g. human faces, cars, simple objects, etc.

Therefore, the Cochrane Collaboration recommends that it should not be used, except in clinical trials. In acoustic droplet vaporization (ADV), albumin is sometimes used as a surfactant. ADV has been proposed as a cancer treatment by means of occlusion therapy. Human serum albumin may be used to potentially reverse drug/chemical toxicity by binding to free drug/agent.

Version 6 also provides enhanced interoperability with NUKE developed by The Foundry. Version 6 incorporated OpenCL acceleration. Version 7, released in July 2018, now incorporates more than 140 effects nodes and a sequence editor. A pin-warp clone brush was added as well as a new planar tracking system capable of tracking non-textured objects with partial occlusion.

These horse may also have had a history of passing enteroliths in their manure. Level of pain is related to the degree of luminal occlusion. Abdominal radiographs can confirm the diagnosis, but smaller enteroliths may not be visible. In rare instances, enteroliths may be palpated on rectal examination, usually if they are present in the small colon.

From 1962-63 Rawling held a position as a visiting fellow at the Research School of Social Sciences, Australian National University, Canberra, during which time he worked on the manuscript of a history of the CPA. Rawling died at Sydney Hospital of a coronary occlusion on 7 March 1966. He was survived by his wife, Mary, and three daughters.

The very dangerous cotton ball diet surfaced in 2013, prompting dieters to eat up to five cotton balls at a time to lower hunger, leading to intestinal occlusion and potentially death. Aseem Malhotra has promoted a low-carbohydrate fad diet known as the Pioppi diet.Mellor, Duane. (2017). "Dietitians like me don't take the Pioppi Diet seriously".

Fowler did not long survive her retirement from politics; she died in King George V Memorial Hospital on 11 May 1954 from coronary occlusion and was buried in Rookwood Cemetery with Methodist rites. She was survived by a daughter. The federal division of Fowler is named for her, as is Fowler Place, in the Canberra suburb of Chisholm.

Viggo Andersen first used this appliance on his daughter's mandibular teeth in the summer of 1908. He took the mechanical braces off from his daughter, and he had her wear the "Biofunctional Retainer" throughout the summer in the mandibular arch. The maxillary arch received Hawley retainer. After a while, Viggo realized that her daughter's occlusion remained the same.

In the worst cases acute limb ischaemia progresses to critical limb ischaemia, and results in death or limb loss. Early detection and steps towards fixing the problem with limb-sparing techniques can salvage the limb. Compartment syndrome can occur because of acute limb ischaemia because of the biotoxins that accumulate distal to the occlusion resulting in edema.

The prognosis for each patient with esotropia will depend upon the origin and classification of their condition. However, in general, management will take the following course: # Identify and treat any underlying systemic condition. # Prescribe any glasses required and allow the patient time to 'settle into' them. # Use occlusion to treat any amblyopia present and encourage alternation.

The popliteal artery entrapment syndrome is a rather uncommon pathology, which results in claudication and chronic leg ischemia. The popliteal artery may be compressed behind the knee, due to congenital deformity of the muscles or tendon insertions of the popliteal fossa. This repetitive trauma may result in stenotic artery degeneration, complete artery occlusion or even formation of an aneurysm.

Hyperosmolar hyperglycemic state (HHS) is a complication of diabetes mellitus in which high blood sugar results in high osmolarity without significant ketoacidosis. Symptoms include signs of dehydration, weakness, leg cramps, vision problems, and an altered level of consciousness. Onset is typically over days to weeks. Complications may include seizures, disseminated intravascular coagulopathy, mesenteric artery occlusion, or rhabdomyolysis.

Budd–Chiari syndrome is a very rare condition, affecting one in a million adults. The condition is caused by occlusion of the hepatic veins that drain the liver. It presents with the classical triad of abdominal pain, ascites, and liver enlargement. The formation of a blood clot within the hepatic veins can lead to Budd–Chiari syndrome.

By darkening areas of texture maps corresponding to corners, joints and recesses, and applying them via self-illumination or diffuse mapping, a radiosity-like effect of patch interaction could be created with a standard scanline renderer (cf. ambient occlusion). Static, pre- computed radiosity may be displayed in realtime via Lightmaps on current desktop computers with standard graphics acceleration hardware.

GA1 was considered as a "treatable disease". Two thirds of the patients who have GA1 will receive little benefit from the treatment for GA1 but can benefit from treatments given to victims of middle cerebral artery occlusion, AIDS dementia and other basal ganglia disorders: brain implants, stem cell neurorestoration, growth factors, monoaminergic agents, and many other neurorehabilitation strategies.

Some newly developed dexamethasone implants, such as Ozurdex, are made from biodegradable materials that could be intravitreally injected rather than surgically implanted. This corticosteroid is usually used to treat disorders and diseases including macular edema secondary to retinal vein occlusion, pseudophakic cystoid macular edema, macular edema secondary to uveitis, diabetic macular edema, and age-related macular degeneration.

Approximately 20% of female infertility can be attributed to tubal causes. Distal tubal occlusion (affecting the end towards the ovary) is typically associated with hydrosalpinx formation and often caused by Chlamydia trachomatis. Pelvic adhesions may be associated with such an infection. In less severe forms, the fimbriae may be agglutinated and damaged, but some patency may still be preserved.
|

Midsegment tubal obstruction can be due to tubal ligation procedures as that part of the tube is a common target of sterilization interventions. Proximal tubal occlusion can occur after infection such as a septic abortion. Also, some tubal sterilization procedures such as the Essure procedure target the part of the tube that is near the uterus.

He also had leading roles in many industrial and educational schools. He supplied equipment and prizes to the Department of Electrical Engineering at Monash University, and is honoured by having the high voltage laboratory named after him. Wilson's health declined from 1966, and he died of a coronary occlusion on 30 March 1972 at Glen Waverley.

Ambient lighting can be combined with ambient occlusion to represent how exposed each point of the scene is, affecting the amount of ambient light it can reflect. This produces diffused, non-directional lighting throughout the scene, casting no clear shadows, but with enclosed and sheltered areas darkened. The result is usually visually similar to an overcast day.

He made several television appearances from 1949 until his death, especially in westerns. He was featured in nine episodes of The Lone Ranger during the final decade of his life. On Broadway, Lynn appeared in Gasoline Gypsies (1931). He was born in Muscatine, Iowa, and died in Hollywood, California from ventricular fibrillation due to a coronary occlusion.

The association of normal tension glaucoma with the syndrome has recently been confirmed by a group of Chinese researchers. In a 2016 review on the risk factors for normal tension glaucoma by ophthalmologists from Asia (where this form of glaucoma is much more prevalent than in Europe or North America), Flammer syndrome has been attributed to increase the likelihood of ganglion cell damage in these patients with disc hemorrhages as a characteristic clinical sign. Migraine attacks, a common feature of Flammer syndrome, have been described as a risk factor for glaucoma progression, in open-angle glaucoma as well as in normal tension glaucoma. Flammer syndrome may also predispose to other eye diseases such as vascular occlusion (especially retinal vein occlusion) in relatively young people or central serous retinopathy.

Strictly speaking, alternating occlusion is a form of visual deprivation and as such may have negative effects during a critical period of development. Experiments on kittens that were published 1965 by Hubel and Wiesel showed that continuously submitting kittens at a young age to a protocol under which the eyes were alternatingly occluded on a day-by-day basis over a prolonged period of time led to changes in the visual cortex, in particular a disruption in cellular connections that would normally enable binocular vision. Experiments with rearing young kittens under rapidly alternating monocular occlusion using constantly-worn electronic goggles showed that cortical binocularity was reduced if the flicker rate was 2 Hz or lower, and that binocularity developed normally if it was 2.5 or 3 or 5 Hz.

Sucker Punch was using around 30% of the Cell processor by the end of Infamous, and for Infamous 2, they were "creeping up over 50 and 60%, because [they] know how to put things on to the Cell processor." With the additional power, Sucker Punch was able to "have more characters on-screen, more complicated shaders, and much greater layering". For the game, a new method of ambient occlusion (AO) was developed, a hybrid of precomputed AO and dynamic AO. The new method was used to render contact shadows and self-occlusion for moveable objects and was meant to complement the other methods of AO already used. On March 1, 2011 Sucker Punch announced a mission creation feature for Infamous 2 that had been in development since 2009.

Wax-ups are indicated where changes to the occlusion or aesthetics are planned. Diagnostic wax-ups are when changes are made to the shapes of the teeth by methodically adding wax to the articulated stone casts representing the patient's teeth. This can be done in order to demonstrate to the patient what the planned restorations will look like, but can also be invaluable when simulating different occlusal schemes, studying the functional occlusion as well as providing temporary coverage whilst the restoration is being constructed by the lab through use of a matrix. Once an established plan has been constructed using the wax-ups, these can be used as a tool to guide the desired outcome in the mouth and provide a useful communication tool with both the dental laboratory and the patient.

Borovansky died of a coronary occlusion on 18 December 1959 at Randwick, and was buried with Anglican rites in Box Hill Cemetery, Melbourne. He was survived by his wife; they had no children. His company provided the basis for the creation of a national Australian company. The artistic director of the Borovansky Ballet, Peggy van Praagh, founded the Australian Ballet in 1962.

Expandable metallic stents have been used as part of a procedure to dilate and maintain stenotic vena cava. Experiments carried out on mongrel dogs resulted in some failures for dilation and early migration, and occlusion complications in patients. Immediate relief of persisting symptoms occurred in two patients. Double balloon dilation is another technique used to treat stenosis of the vena cava.

Retinal arterial occlusion is an ophthalmic emergency, and prompt treatment is essential. Completely anoxic retina in animal models causes irreversible damage in about 90 minutes. Nonspecific methods to increase blood flow and dislodge emboli include digital massage, 500 mg IV acetazolamide and 100 mg IV methylprednisolone (for possible arteritis). Additional measures include paracentesis of aqueous humor to decrease IOP acutely.

Orodromeus was a small fast bipedal herbivore that probably coexisted with dinosaurs such as Daspletosaurus and Einiosaurus. Its length was estimated by Horner & Weishampel at 2.5 metres. Orodromeus is distinguished by a palpebral that is at its back attached to the postorbital; a boss on the jugal; a non-fused wrist; and triangular maxillary and dentary teeth with a vertical occlusion.

Associated musculoskeletal findings are sometimes reported. When it occurs with acne conglobata, hidradenitis suppurativa, and pilonidal cysts, the syndrome is referred to as the follicular occlusion triad or tetrad. Lyme disease can be misdiagnosed as cellulitis. The characteristic bullseye rash does not always appear in Lyme disease (the rash may not have a central or ring-like clearing, or not appear at all).

Lightmaps in games are usually colored texture maps, or per vertex colors. They are usually flat, without information about the light's direction, whilst some game engines use multiple lightmaps to provide approximate directional information to combine with normal-maps. Lightmaps may also store separate precalculated components of lighting information for semi-dynamic lighting with shaders, such as ambient-occlusion & sunlight shadowing.

Willie Fung was a Chinese film actor who played supporting roles in 125 American films between 1922 and 1944. Born in Canton, China, Fung made his film debut in 1922 in Hurricane's Gal. The majority of his roles were in Westerns and dramas. Fung died of a coronary occlusion in Los Angeles on 16 April 1945 at the age of 49.

The umbilical cord of the acardiac twin may be surgically cut, separating it from the pump twin, a procedure called fetoscopic cord occlusion. Or a radio-frequency ablation needle may be used to coagulate the blood in the acardiac twin's umbilical cord. This last procedure is the least invasive. These procedures greatly increase the survival chances of the pump twin, to about 80%.

When forces are increased, the bony trabeculae also increase in number and thickness and bone is added to the external surfaces. The periodontal ligament depends on stimulation provided by function to preserve its structure. Within physiologic limits the PDL can accommodate increased function by increasing its width. Forces that exceed the adaptive capacity of the periodontium produce injury called trauma from occlusion.

There is also a talon-like platform anterior to the prominent cusps. The tooth also has a strong and wide lingual and buccal cingula. There are wear facets on the molar to suggest occlusion with the lower molars. In Tikitherium, the wear facets are found on the lingual side unlike with Woutersia where the wear facets are found only on the anterior face.

Normal adult hemoglobin A molecule comprises two α and two β globin chains associated with a heme ring. Mutation at the 6th position of the beta chain is the cause of sickle cell disease. Due to sickle cell disease, vascular occlusion may occur in the conjunctiva, iris, retina, or choroid. Retinal changes occur due to blockage of retinal blood vessels by abnormal RBCs.
|
|
A sudden blockage of a coronary artery may result in a heart attack. A blockage of an artery supplying the brain can cause a stroke. If the development of the stenosis or occlusion is gradual, blood supply to the tissues and organs slowly diminishes until organ function becomes impaired. At this point tissue ischemia (restriction in blood supply) may manifest as specific symptoms.

Irving Glickman (January 17, 1914 – October 1, 1972) was an American clinical researcher in the field of periodontology and author. He was one of the first to classify furcation defects and the role of occlusal trauma on periodontal disease.Jan Lindhe: Trauma from Occlusion: Periodontal Tissues. In Jan Lindhe, editor: Clinical Periodontology and Implant Dentistry, 5th Edition, Blackwell Munksgaard 2008, p. 350.

The lacrimal sac or lachrymal sac is the upper dilated end of the nasolacrimal duct, and is lodged in a deep groove formed by the lacrimal bone and frontal process of the maxilla. It connects the lacrimal canaliculi, which drain tears from the eye's surface, and the nasolacrimal duct, which conveys this fluid into the nasal cavity. Lacrimal sac occlusion leads to dacryocystitis.

The engine is purely software-based; it does not rely on hardware-acceleration via a 3D graphics card. Outcast features effects such as character shadows, depth of field, bump mapping and reflections. Anti-aliasing is used to smooth certain texture boundaries. The heightmap engine renders reliefs with self- occlusion, motion parallax, and silhouettes (but no shadowing)--even for details such as cobblestones.

It was rendered on Sun Microsystems' grid computing facility Sun Grid. As in Elephants Dream, Blender developers worked extensively to improve the software in accordance with the needs of the movie team. Improvements were made in hair and fur rendering, the particle system, UV mapping, shading, the render pipeline, constraints, and skinning. Also introduced during the project was approximate ambient occlusion.

Next, the nose and lips are reconstructed before any of the other muscles are formed. The lips are approximately as wide as the interpupillary distance. However, this distance varies significantly with age, sex, race, and occlusion. The nose is one of the most difficult facial features to reconstruct because the underlying bone is limited and the possibility of variation is expansive.

Trauma to the spinal cord, such as neck hyperflexion injuries, are often the result of car accidents or sports-related injuries. In such injuries, posterior dislocations and extensions occur without the rupture of ligaments. This blunt trauma may be further complicated with subsequent disc compression. In addition to these complications, transient ischemic attacks could occur in the spinal cord during spinal artery occlusion.

In some cases - approximately 20% of the population - there is a branch of the ciliary circulation called the cilio-retinal artery which supplies the retina between the macula and the optic nerve, including the nerve fibers from the foveal photoreceptors. If this artery is present, the central vision will be preserved even in case of central retinal artery occlusion (CRAO).

Typically, the lateral incisors are missing. The enamel (outermost layer of the tooth) is commonly found to be hypomineralized and hypoplastic, making the teeth more likely to decay. As CLP can make oral hygiene more difficult, there is an increased rate of cavities. In addition, abnormal positioning of individual teeth may affect occlusion, which can create an open bite or cross bite.

Other middleware is used for performance optimisation - for example 'Simplygon' helps to optimise and generate level of detail meshes, and 'Umbra' adds occlusion culling optimisations to 3d graphics. Some middleware contains full source code, others just provide an API reference for a compiled binary library. Some middleware programs can be licensed either way, usually for a higher fee for full source code.

In World Series play, he recorded no decisions in three appearances, with a 4.50 earned run average and 1 strikeout. On July 19, 1924, Bell became the last pitcher in Major League history to start and win both ends of a double header. Bell died from a coronary occlusion in 1949 at age 51 and is buried at Calvary Cemetery in Los Angeles.

Oscar Tiegs' geographical isolation, and his own diffidence probably prevented him from maximising his contribution to zoology, although rather than diffidence others describe it as an unassuming disposition. He is described as shy and reserved, preferring the laboratory to the committee meeting or social function. He suffered from aortic stenosis, and died of a coronary occlusion in his home in Hawthorn, aged 59.

Embolectomy is the emergency surgical removal of emboli which are blocking blood circulation. It usually involves removal of thrombi (blood clots), and is then referred to as thrombectomy. Embolectomy is an emergency procedure often as the last resort because permanent occlusion of a significant blood flow to an organ leads to necrosis. Other involved therapeutic options are anticoagulation and thrombolysis.

Venous thromboembolism (VTE) is a common peripheral venous disease. It is defined by the occlusion of venous blood vessels by blood clots. There are two major types of VTE: deep-vein thrombosis (DVT) and pulmonary embolism. DVT is often found in the calf, accompanies with the swelling of limbs along the deep vein while pulmonary embolism causes chronic pulmonary hypertension.

The purported purpose is to enhance effective travel coupled with the use of dark sleep shades for total occlusion during the intense year long training schedule. The object of simulating total blindness according to various articles and opinions published in the Braille Monitor (an NFB Publication) is to prepare the student for such a time when they might become totally blind. Some medical professionals hold the opinion that such total occlusion practice actually exacerbates the deterioration of sight in those who might still have a remainder of limited or partial sight. The NFB has always stressed that the blind citizen is to be taught to travel, not simply by memorizing specific routes, but by practicing going to unfamiliar places using the long cane and even wearing blindfolds, called sleep shades, if they have any residual vision.

For example, if the user was looking for a face, the eigenspaces may consist of images (templates) of faces in different positions to the camera, in different lighting conditions, or with different expressions. It is also possible for the matching image to be obscured, or occluded by an object; in these cases, it is unreasonable to provide a multitude of templates to cover each possible occlusion. For example, the search image may be a playing card, and in some of the search images, the card is obscured by the fingers of someone holding the card, or by another card on top of it, or any object in front of the camera for that matter. In cases where the object is malleable or poseable, motion also becomes a problem, and problems involving both motion and occlusion become ambiguous.

There are four main types of teeth in humans, shown labelled here. Dental anatomy is a field of anatomy dedicated to the study of tooth structure. The development, appearance, and classification of teeth fall within its field of study, though dental occlusion, or contact between teeth, does not. Dental anatomy is also a taxonomic science as it is concerned with the naming of teeth and their structures.

Steep parallax mapping is one name for the class of algorithms that trace rays against heightfields. The idea is to walk along a ray that has entered the heightfield's volume, finding the intersection point of the ray with the heightfield. This closest intersection is what part of the heightfield is truly visible. Relief mapping and parallax occlusion mapping are other common names for these techniques.

A post-tropical cyclone is formed when the typical characteristics of a tropical cyclone are replaced with those of extratropical cyclones, otherwise known as extratropical transition. After the initial formation, a post-tropical cyclone has the potential to gain strength and intensity by forming an extratropical storm. If a post-tropical cyclone does become an extratropical storm, it will eventually decay through the process of occlusion.

She was an active worker for the American Red Cross during World War II and later served as board chairman of the Association for the Preservation of Tennessee Antiquities. Dudley died unexpectedly on September 13, 1955, of a coronary occlusion at her home in Belle Meade, Tennessee. She was 78 years old. She is buried with her family at Mount Olivet Cemetery in Nashville.

Once the sound is able to reach the cochlea at normal or near-normal levels, the cochlea and auditory nerve are able to transmit signals to the brain normally. Common issues with hearing aid fitting and use are the occlusion effect, loudness recruitment, and understanding speech in noise. Once a common problem, feedback is generally now well-controlled through the use of feedback management algorithms.

Their skull construction allows for a strong chewing mechanism called a transverse power stroke. This, paired with their bilateral dental occlusion, made them extremely effective as herbivores. Members of Iguanodontidae are thought to have had a diet that consisted of both gymnosperms and angiosperms, the latter of which co-evolved with the iguanodontids in the Cretaceous period. There is no consensus on the phylogeny of the group.

Cork, Ireland in 1927 Wiggle stereoscopy is an example of stereoscopy in which left and right images of a stereogram are animated. This technique is also called wiggle 3-D or wobble 3-D, sometimes also Piku-Piku (Japanese for "twitching").Simulated 3D—Wiggle 3D, Shortcourses.com The sense of depth from such images is due to parallax and to changes to the occlusion of background objects.

Sphincter pharyngoplasty is mostly used for horizontal clefts of the soft palate. Two small flaps are made on the left and right side of the entrance to the nasal cavity, attached to the back of the throat. For good results, the patient must have good palatal motion, as the occlusion of the nasal cavity is mainly carried out by muscles already existing and functioning.

There are several causes of Beau's lines. It is believed that there is a temporary cessation of cell division in the nail matrix. This may be caused by an infection or problem in the nail fold, where the nail begins to form, or it may be caused by an injury to that area. Some other reasons for these lines include trauma, coronary occlusion, hypocalcaemia, and skin disease.

|
Because of the lack of opposing force and the natural eruptive potential of the tooth there is a tendency for the tooth to erupt out of the line of the occlusion. Not all teeth lacking an opposing tooth overerupt, even in long term. Unopposed upper jaw molars overerupt more than the unopposed lower jaw molars. It is more severe in young people and periodontically affected people.

Treatment with emollients is used to relieve symptoms of cracking and dryness. Application of lubricants under plastic occlusion before bedtime appears to aid removal of scales on hands and feet. Other topical options include: topical corticosteroids alone, or combined with keratolytics, such as urea and vitamin D3 analogues. The most effective therapy is long term use of oral retinoids, such as acitretin and isotretinoin.

It is also of the utmost importance when correcting these mandibular anomalies that the teeth result in a good occlusion with the opposing dentition of the maxilla. If this is not done satisfactorily occlusal instability may be created leading to a plethora of other issues. In order to correct mandibular anomalies it is common for a complex treatment plan which would involve surgical intervention and orthodontic input.

Goldberg classified PSR into following 5 different self-explanatory stages: # Stage of peripheral arterial occlusion and ischemia: It is the earliest abnormality that can be visualized by fundus examination. The occluded arterioles can be seen as dark red lines. They eventually turn into white silver-wire vessels. # Stage of peripheral arteriolar-venular anastomoses: Arteriolar-venular anastomoses develop as blood is diverted from blocked arteries to nearby venules.

The superficial system is not adequate to handle the large volume of blood being delivered to the leg via the arterial system. The result is edema, pain and a white appearance (alba) of the leg. The next step in the disease progression is occlusion of the superficial venous system, thereby preventing all venous outflow from the extremity. At this stage it is called phlegmasia cerulea dolens.

The patient needed emergency surgery due to a knife wound. Cappelen accessed the thoracic cavity by cutting through the fourth rib. He repaired the wound of the left ventricle where he has sustained the stab wounds in the left side of his chest. After two days of intensive care, the patient died of coronary occlusion and not because of the repairing of the heart.

A volvulus is a twist along the axis of the mesentery, a torsion is a twist along the longitudinal axis of the intestine. Various parts of the horse's gastrointestinal tract may twist upon themselves. It is most likely to be either small intestine or part of the colon. Occlusion of the blood supply means that it is a painful condition causing rapid deterioration and requiring emergency surgery.

Ruptures of the fibrous cap expose thrombogenic material, such as collagen, to the circulation and eventually induce thrombus formation in the lumen. Upon formation, intraluminal thrombi can occlude arteries outright (e.g., coronary occlusion), but more often they detach, move into the circulation, and eventually occlude smaller downstream branches causing thromboembolism. Apart from thromboembolism, chronically expanding atherosclerotic lesions can cause complete closure of the lumen.

For instance, you can add lots of cool additional enhancements like depth of field, ambient occlusion, various types of color correction and a whole lot more […]. It's also worth noting that this version of Dolphin helps avoid the shader compilation stutters that plagued the official release of the emulator and it leads to a much more fluid experience.” As with Dolphin, development is hosted on GitHub.

Puckett after the 1995 season was forced to retire at age 35 due to loss of vision in one eye from a central retinal vein occlusion. He retired as the Twins' all-time leader in career hits, runs, doubles, and total bases. At the time of his retirement, his .318 career batting average was the highest by any right-handed American League batter since Joe DiMaggio.

This can be seen to affect the whole length of the coronary arteries and often the smaller arteries. Calcification does not always occur in CAV and if it does appear, it happens late. The compensatory arterial dilation does not occur in CAV. Unlike in nontransplanted people with coronary artery disease due to atherosclerosis, in CAV occlusion with thrombus of the vessel lumen is rare.

Another challenge posed by using Internet image search results as training sets for classifiers is that there is a high amount of variability within object categories, when compared with categories found in hand-labeled datasets such as Caltech 101 and Pascal. Images of objects can vary widely in a number of important factors, such as scale, pose, lighting, number of objects, and amount of occlusion.

The typical pathology of infection with these parasites includes anaemia and enlargement of the liver and spleen. Gross lesions also include pulmonary congestion and pericardial effusion. Megaloschizonts appear as grey-white nodules found in the heart, liver, lung or spleen. Microscopically there is ischemic necrosis and associated inflammation in the heart, brain, spleen and liver due to occlusion of blood vessels by megaloschizonts in endothelial cells.

An occlusion can often be diagnosed using Doppler sonography (a form of ultrasound). Some medical procedures, such as embolisation, involve occluding a blood vessel to treat a particular condition. This can be to reduce pressure on aneurysms (weakened blood vessels) or to restrict a haemorrhage. It can also be used to reduce blood supply to tumours or growths in the body, and therefore restrict their development.

The three major arteries of the cerebellum: the SCA, AICA, and PICA. (Posterior inferior cerebellar artery is PICA.) Human brainstem blood supply description. PICA is #12. It is the clinical manifestation resulting from occlusion of the posterior inferior cerebellar artery (PICA) or one of its branches or of the vertebral artery, in which the lateral part of the medulla oblongata infarcts, resulting in a typical pattern.

A brief period of coronary arterial occlusion followed by reperfusion prior to prolonged ischemia is known as preconditioning. It has been shown that this is protective. Preconditioning preceded myocardial infarction, may delay cell death and allow for greater salvage of myocardium through reperfusion therapy.Murry, C.E., Jennings, R.B. & Reimer, K.A.. Preconditioning with ischaemia: a delay of lethal cell injury in ischemic myocardium. Circulation 74, 1124–1136.

After the war, Irwin returned to the United States and became commander of V Corps in 1946 and director of the Military Intelligence Division in 1948. He finished his military career as the commander of U.S. Army forces in Austria from 1950 to 1952 when he retired due to medical problems. Lt. Gen. Irwin died in 1955 of a coronary occlusion in Asheville, North Carolina.

It is important to note that Tweed's philosophy was different than Edward Angle, his mentor. Edward Angle practiced strictly without extraction of teeth to achieve harmonious occlusion. Tweed believed that extracting teeth lead to a more harmonious profile than what Angle achieved in his practice and was the best technique to prevent orthodontic relapse. In 1940, Tweed took 100 patients and treated them without extractions.

Most bleeding from instrumentation are minor and would settle spontaneously. When indicated, management is directed towards stopping bleeding and relieving obstruction if present, which is achieved either by surgical ligation of hepatic artery or by endoscopic embolisation. Endoscopic trans-arterial embolisation (TAE) is preferred initially because of high success rate and less complication. TAE involves the selective catheterization of a hepatic artery followed by embolic occlusion.

It is a very useful technique for detecting changes in images due to its simplicity and ability to deal with occlusion and multiple motions. These techniques assume constant light source intensity. The algorithm first considers two frames at a time and then computes the pixel by pixel intensity difference. On this computation it thresholds the intensity difference and maps the changes onto a contour.

The third common mechanism is occlusion of blood flow. This can be caused by either physically blocking the vessels of the retinal artery branches or causing the arteries to narrow. Again, the end result is reduced blood flow to the retina causing tissue damage. Sickle cell disease compromises blood flow by causing blood to sludge, or thicken and flow slowly, through the retinal arteries.

He logged six shutouts and 28 complete games, and earned six saves. Fannin's best season was probably , when he went 10–14, with ten complete games, and 102 strikeouts, the only season he struck out more than 100. Over his MLB career, Fannin allowed 763 hits and 393 bases on balls in 733 innings. He died at age 42 in Sandusky, Ohio, of a coronary occlusion.

Radiosurgery is itself not without risk. In one large study, nine percent of patients had transient neurological symptoms, including headache, after radiosurgery for AVM. However, most symptoms resolved, and the long-term rate of neurological symptoms was 3.8%. Neuroendovascular therapy Embolization is performed by interventional neuroradiologists and the occlusion of blood vessels most commonly is obtained with Ethylene-vinyl alcohol copolymer (Onyx) or N-butyl cyanoacrylate (NBCA).

Wilson Lloyd "Chick" Fewster (November 10, 1895 – April 16, 1945) was an American professional baseball second baseman. He played eleven seasons in Major League Baseball (MLB) between 1917 and 1927 for the New York Yankees, Boston Red Sox, Cleveland Indians, and Brooklyn Robins. In his career, he hit six home runs and drove in 167 RBI. He died of coronary occlusion at age 49.

After the New York University College of Dentistry was bought by New York University, Stanton became a Professor in the Department of Preventative Dentistry and Occlusion. He was the first person to teach the subject of in a dental curriculum. He also became Professor in the Orthodontic Department until 1933. He eventually retired in 1937 after organizing a division of child research at NYU.

Management of teeth with PFE can include extractions of affected teeth, followed by orthodontic space closure or placement of a prosthetic implant with a bone graft. This option can only be applied to a single tooth that is affected. If multiple teeth are affected then, a segmental osteotomy may be performed to bring the entire segment into occlusion. However, minimal success has been shown following this procedure.

The new card was to have been released as Avalanche3D by the end of 2001. The third development, codenamed Hammer, started development as Axe lost viability toward the end of 2001. This new card was to be a high-end DirectX 9 part, offering new features such as occlusion culling, improved rendering performance and various other innovations. This version, like the ones before it, never shipped commercially.

Very advanced luminal occlusion usually produces a heart attack. However, it has been increasingly recognized, since the late 1980s, that coronary catheterization does not allow the recognition of the presence or absence of coronary atherosclerosis itself, only significant luminal changes which have occurred as a result of end stage complications of the atherosclerotic process. See IVUS and atheroma for a better understanding of this issue.

Zhang proposes a modified k-d tree algorithm for efficient closest point computation. In this work a statistical method based on the distance distribution is used to deal with outliers, occlusion, appearance, and disappearance, which enables subset- subset matching. There exist many ICP variants, from which point-to-point and point-to-plane are the most popular. The latter usually performs better in structured environments.

|
If bleeding is detected, treatment can range from transfusion to reoperation. Later on in the hospital course, common complications include wound infections, pneumonia, urinary tract infection, and graft occlusion. At discharge, patients are often prescribed oral painkillers, and should be prescribed a statin and an anti-platelet medication if not contraindicated and their bypass was performed for atherosclerosis, (e.g., peripheral vascular disease or coronary artery disease).

The most serious parasitic crustaceans among fish in general are sea lice. However, L. branchialis is probably the most serious parasitic crustacean among cod. Infestation reduces the efficiency with which food can be utilised, delaying the development of the gonads. Up to 30% loss in weight can occur, with increases in mortality because of open lesions with loss of blood, and possibly occlusion of vessels or aorta.

Pulmonary veno-occlusive disease may have a genetic basis, published reports have indicated fatal occurrences that appeared to possess a familial pattern, more to the point, a germline mutation. The pathophysiology of veno-occlusive disease culminates in occlusion of the pulmonary blood vessels. This could be due to edematous tissue (sclerotic fibrous tissue). Thickening is identified in lobular septal veins, also dilatation of lymphatics happens.

An occlusion event tests the knowledge that an object exists even if it is not immediately visible. Jean Piaget originally called this concept object permanence. When Piaget formed his developmental theory in the 1950s, he claimed that object permanence is learned, not innate. The children's game peek-a-boo is a classic example of this phenomenon, and one which obscures the true grasp infants have on permanence.

Clyde Lanham Hurley, Jr. (September 3, 1916 – August 14, 1963) was a trumpeter during the big band era. He was born in Fort Worth, Texas to Clyde Lanham Hurley and Esther Brown. Scott Yanow describes Hurley as "a fine trumpeter with a fat tone and a hard-driving style". He died of a coronary occlusion in Fort Worth leaving two sons and a former wife.

When a hydrosalpinx is detected by an HSG it is prudent to administer antibiotics to reduce the risk of reactivation of an inflammatory process. When laparoscopy is performed, the surgeon may note the distended tubes, identify the occlusion, and may also find associated adhesions affecting the pelvic organs. Laparoscopy not only allows for the diagnosis of hydrosalpinx, but also presents a platform for intervention (see management).

Small vessels like vasa vasorum and vasa nervorum are particularly susceptible to external mechanical compression. A decrease in blood flow through the vasa nervorum has been implicated in the development of diabetic neuropathy. Arteritis of the vasa nervorum leads to mononeuritis multiplex or polyneuropathy. Occlusion of vasa nervorum at the level of the epineurial arterioles leads to ischemia of nerves, leading to vasculitic neuropathy.

These methods use appearance information gathered from pre-captured or pre-computed projections of an object to match the object in the potentially cluttered scene. However, they do not take the 3D geometric constraints of the object into consideration during matching, and typically also do not handle occlusion as well as feature-based approaches. See [Murase and Nayar 1995] and [Selinger and Nelson 1999].

In these circumstances, in order to accurately stimulate mandibular movement around CR (particularly opening and closing of the mouth), using a facebow transfer, the maxillary cast should be mounted in a semi- adjustable articulator and then the mandibular cast should be mounted using a CR registration. The patients new occlusion is then arranged so that the new ICP occurs when patient is in CR.

Shadow as a term is often used for any occlusion or blockage, not just those with respect to light. For example, a rain shadow is a dry area, which with respect to the prevailing wind direction, is beyond a mountain range; the elevated terrain impedes rainclouds from entering the dry zone. An acoustic shadow occurs when direct sound has been blocked or diverted around a given area.

A steep incisal guidance angle (the angle formed between the sagittal plane when the incisors are in centric occlusion and the horizontal plane) must be reduced in order to decrease excessive horizontal forces on anterior teeth, which would lead to failure.Mizrahi, Basil. (2006). The Dahl principle: Creating space and improving the biomechanical prognosis of anterior crowns. Quintessence international (Berlin, Germany: 1985). 37. 245-51.

Frank Rio died at noon on February 23, 1935. The cause of death was a coronary occlusion, causing a heart attack. Associates in the Chicago Outfit took charge of his remains and had him buried. Police later said that gang members became involved in his burial because they wanted to divide up Rio's gang-owned assets before news of his death hit the streets.

In the 1949 election the Chifley government was defeated by the Liberal/Country Party coalition led by Prime Minister Robert Menzies and Rosevear lost the Speakership. He continued to sit in the House until his death of coronary occlusion on 21 March 1953. He was survived by his wife, a son and a daughter. A portrait of Rosevear by Joshua Smith won the Archibald Prize in 1944.

The Curve of Spee is basically a part of a circle (8-inch diameter) which has its circumference as the anterior ramus of mandible. Ideally, it is aligned so that a continuation of this arc would extend through the condyles. The curvature of this arc would relate, on average, to part of a circle with a 4-inch radius. It is the only Anteroposterior curve of occlusion.

Schmidt's state funeral procession in Hamburg, 23 November 2015 On 2 September 2015, Schmidt underwent surgery for a vascular occlusion in his right leg. On 17 September, Schmidt was discharged from hospital. After initial improvement, his condition worsened again on 8 November, with his doctor saying he "feared for the worst." Schmidt died in his Hamburg home on the afternoon of 10 November 2015, aged 96.

Phlegmasia cerulea dolens (literally: painful blue inflammation) is an uncommon severe form of deep venous thrombosis which results from extensive thrombotic occlusion (blockage by a thrombus) of the major and the collateral veins of an extremity. It is characterized by sudden severe pain, swelling, cyanosis and edema of the affected limb. There is a high risk of massive pulmonary embolism, even under anticoagulation. Foot gangrene may also occur.

Due to his sporting history, Chandler was a member of the 1956 Summer Olympics organising committee. He later served as chairman of the Melbourne Cricket Ground in 1973 and 1974. He died of a coronary occlusion in 1974, at the William Angliss Hospital, which he had been co-founder and president of since 1939. An agricultural college called the Gilbert Chandler Institute of Dairy Technology at Werribee was named after him.

A region of the conserved structure of SAM–SAH riboswitches includes a predicted Shine-Dalgarno sequence (ribosome-binding site) of the downstream metK genes. These nucleotides are required for optimal binding to the ligand and might form a pseudoknot with the terminal loop within the main stem-loop structure. Occlusion of the Shine-Dalgarno sequence might be the mechanism by which SAM–SAH riboswitches regulate expression of the downstream genes.

American evidence-based clinical guidelines were published in 2016 for the treatment of VTE. In the UK, guidelines by the National Institute for Health and Care Excellence (NICE) were published in 2012, updated in 2020. These guidelines do not cover rare forms of thrombosis, for which an individualized approach is often needed. Central and branch retinal vein occlusion does not benefit from anticoagulation in the way that other venous thromboses do.

The use of endovascular modalities for bleeding control and treatment on hemodynamically unstable trauma patients is increasing. Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) for hemorrhage control, angioembolization and stent grafts are highly established tools used for both arterial and venous hemorrhage in both traumatic and non- traumatic patients. To be able to provide an endovascular opportunity for resuscitation requires good organization and a well-established endovascular team.

This shape is due to the blockage/occlusion of small arteries. Individuals may be diagnosed with the benign form if only the papules are present. However, an individual may be diagnosed with the malignant form if involvement of other organs like the lungs, intestine and/or central nervous system occurs. The malignant, or systematic form of this condition may suddenly develop even after having papules present for several years.

On October 27, 1957, Tony Morabito died of a heart attack while watching the 49ers play the Chicago Bears at Kezar Stadium. Having suffered a coronary occlusion in 1952 Tony had been living on "borrowed time". Doctors citing the dangerous, high emotional factors of football urged him to get out of football. The 49ers were losing 17-7 when a note "Tony's gone" was passed to the coach.

Although many of these milestones were never achieved, in 2006 a total of $28.9M was billed to Bayer under their cost-sharing agreement. In February 2003, Hyseq merged with Variagenics giving birth to “Nuvelo Inc.” to further development of drug “alfimeprase.” This drug therapy was developed against peripheral arterial occlusion or “Leg Attack” disease and was approved as orphan drug status. This accelerated the clinical development of alfimeprase.

Morganucodon are more closely related to the crown group than is Sinoconodon due to the upper and lower molars have one-to-one occlusal relationship and the opposing molars develop wear facets from this precise deal occlusion. Morganucodon are also more similar to the crown mammalian group than Sinoconodon in a number of features of the cranio-mandibular joint, a longer cochlear canal, and a slightly larger cranial capacity.

Cunningham was a staunch opponent of Jack Lang and his party, and stood for the Legislative Assembly seat of Coogee after Lang's removal as leader. Surprisingly he won in 1941, partly due to his own political skills and partly due to the invigorated Labor under William McKell. Cunningham retained the seat until his death on 23 March 1948 of a coronary occlusion; he was survived by his wife and two sons.

Competing methods for scale invariant object recognition under clutter / partial occlusion include the following. RIFT is a rotation-invariant generalization of SIFT. The RIFT descriptor is constructed using circular normalized patches divided into concentric rings of equal width and within each ring a gradient orientation histogram is computed. To maintain rotation invariance, the orientation is measured at each point relative to the direction pointing outward from the center.

He performed his first operation on a child in Germany in the 1990s. Freudenthal became interested in medical devices. He was part of a team that in March 1998 reported encouraging results of tests on neonatal lambs for occlusion of patent ductus arteriosus with a double-helix device at RWTH Aachen University, Germany. The devices used memory-shaped double-cone stainless steel coils mounted on a titanium/nickel core wire.

In wire-frame rendering, back-face culling can be used to partially address problem of hidden line removal, but only for closed convex geometry. A related technique is clipping, which determines whether polygons are within the camera's field of view at all. Another similar technique is Z-culling, also known as occlusion culling, which attempts to skip the drawing of polygons which are covered from the viewpoint by other visible polygons.

The wear facets on the upper molar suggest a probable occlusal relationship with the lower dentition. However no conclusion can be made about occlusion without a lower dentition specimen. There is also a posterolingual cusp with two shearing crests and basins to indicate mastication via grinding. This molar is the earliest representative of several independent evolutionary developments found in later mammalian groups such as Boreosphenida, Australosphenida, Shuotheriids, and Docodonta.

Amblyopia will be treated via occlusion treatment (using patching or atropine drops) of the non- squinting eye with the aim of achieving full alternation of fixation. Management thereafter will be surgical. As alternative to surgery, also botulinum toxin therapy has been used in children with infantile esotropia. Furthermore, as accompaniment to ophthalmologic treatment, craniosacral therapy may be performed in order to relieve tension (see also: Management of strabismus).

|
As a result, other methods are considered when treating non-growing patients. Follow-ups are often being adopted in the cases of late onset tooth ankylosis. As tooth growth is insignificant, no surgical procedures are needed to treat the ankylosed tooth as long as its height difference with adjacent teeth is small. In some cases where the height difference is more significant, tooth crown build-up is recommended to restore occlusion.

Their ability to repeat words, utterances, or phrases is also affected. Due to the preservation of the right hemisphere, an individual with global aphasia may still be able to express themselves through facial expressions, gestures, and intonation. This type of aphasia often results from a large lesion of the left perisylvian cortex. The lesion is caused by an occlusion of the left middle cerebral arteryAlexander, M.P. & Loverso, Felice. (1992).

An occlusion, or the blocking of all blood flow through a vessel, is considered 100% stenosis. Previously, restenosis was thought to arise due to the development of neointimal thickening as a result of smooth muscle stimulation. However, it is now thought the blood vessel's dilated segment shrinking is the mechanism. This explains why stenting, which increases the luminal area, is so effective in decreasing the occurrence of restenosis.

Avellis syndrome is a neurological disorder characterized by a peculiar form of alternating paralysis. There is paralysis of the soft palate and vocal cords on one side and loss of pain sensation and temperature sense on the other side, including the extremities, trunk, and neck. It usually results from occlusion of the vertebral artery in lesions of the nucleus ambiguous and pyramidal tract. Horner's syndrome may be associated.

Otto Carl Friedrich Westphal (1800 – 1879) was a German physician and Geheimer Sanitätsrath (privy medical counsellor). He wrote on the human eye and on optics. He was interested in environmental impacts on eyesight, including light quality, and argued that eyeglasses should be tailored to occupation. Westphal also examined a variety of eyewashes and tinctures, and reportedly invented eye occlusion therapy, currently used for correction of strabismus and amblyopia.

Other dermatologic problems include squamous-cell carcinoma/dysplasia (vulvar, anal, and facial). Immune problems are also common, including autoimmune hemolytic anemia, severe allergies (both food and environmental), asthma, and reactive airway disease. The nervous system may also be affected; observed conditions in DOCK8 deficient people include hemiplegia, ischemic stroke, subarachnoid hemorrhage, and facial paralysis. Vascular complications are common, including aortic aneurysm, cerebral aneurysm, vessel occlusion and underperfusion, and leukocytoclastic vasculitis.

|
Factor XII deficiency is a rare disorder that is inherited in an autosomal recessive manner. Unlike other clotting factor deficiencies, factor XII deficiency is totally asymptomatic and does not cause excess bleeding. Mice lacking the gene for factor XII, however, are less susceptible to thrombosis. The protein seems to be involved in the later stages of clot formation rather than the first occlusion of damages in the blood vessel wall.
|
|
Other diagnostical tools are duplex ultrasonography, computed tomography angiography (CTA), and magnetic resonance angiography (MRA). The CTA and MRA are used most often because the duplex ultrasonography although non-invasive is not precise in planning revascularization. CTA uses radiation and may not pick up on vessels for revascularization that are distal to the occlusion, but it is much quicker than MRA. In treating acute limb ischaemia time is everything.
|
|
Vascular occlusion is a blockage of a blood vessel, usually with a clot. It differs from thrombosis in that it can be used to describe any form of blockage, not just one formed by a clot. When it occurs in a major vein, it can, in some cases, cause deep vein thrombosis. The condition is also relatively common in the retina, and can cause partial or total loss of vision.

In the 2011–12 season, Stadsgaard suffered a setback when he had a venous occlusion on his left leg and was sidelined for two months. Although he appeared on as an unused substitute, Stadsgaard was expected to leave the club in the January transfer window, with Copenhagen confirmed their interests once again. In January 2012, they made an approach from Malaga of signing him, leading to negotiations soon after.

The complications include rupture, peripheral embolization, acute aortic occlusion, and aortocaval (between the aorta and inferior vena cava) or aortoduodenal (between the aorta and the duodenum) fistulae. On physical examination, a palpable and pulsatile abdominal mass can be noted. Bruits can be present in case of renal or visceral arterial stenosis. The signs and symptoms of a ruptured AAA may include severe pain in the lower back, flank, abdomen or groin.

Normal vision The same view with diabetic retinopathy. Emptied retinal venules due to arterial branch occlusion in diabetic retinopathy (fluorescein angiography) Diabetic retinopathy often has no early warning signs. Even macular edema, which can cause rapid vision loss, may not have any warning signs for some time. In general, however, a person with macular edema is likely to have blurred vision, making it hard to do things like read or drive.

The most common modification is based on Longa (1989) who described filament introduction via the external carotid artery, allowing closure of the access point with preserved blood supply via the common and internal carotid artery to the brain after the removal of the filament. Known pitfalls of this method are insufficient occlusion, subarachnoid hemorrhage , hyperthermia , and necrosis of the ipsilateral extracranial tissue . Filament MCAO is not applicable to all rat strains .

This is similar to the size ridges seen on Kentrosaurus. Like all stegosaurians, the denticles on the teeth are rounded at the tips, in contrast to ankylosaurians. Also, like Huayangosaurus, but unlike Kentrosaurus and Stegosaurus, Paranthodon possesses a prominent buccal margination (a ridge beside the tooth row). Paranthodon teeth preserve wear, but wear is absent on most teeth, similar to Huayangosaurus, meaning it is likely that Paranthodon lacked occlusion between teeth.

Satellite tobacco mosaic virus molecular graphics produced in VMD and rendered using Tachyon. The scene is shown with a combination molecular surfaces colored by a radial distance, and nucleic acids shown in ribbon representations. The Tachyon rendering uses both direct lighting and ambient occlusion lighting to improve the visibility of pockets and cavities. The VMD axes are shown as a simple example of rendering of non-molecular geometry.

However, coronary stenting is contraindicated in drug- refractory individuals who do not have significant organic occlusion of their coronary arteries. For the latter individuals, other, less fully investigated drugs may provide symptom relief. Statins, e.g. fluvastatin, while not evaluated in large-scale double-blind studies, are reportedly helpful in reducing variant angina attacks and should be considered in patients when calcium channel blockers and nitroglycerin fail to achieve good results.

On the other hand, Dr Feinstein and Kurth could not find a definite hinge axis point and settled on a 2 mm area of nonmovement in the condylar region. The right and left condyle have distinct size, shape and angulation. Therefore, the value of hinge axis to determine or help in establishing balanced occlusion could be questioned. To remove occlusal interferences, Schuyler, introduced the BU-LL and MU-DL rule.
|
|
This theory was popularized by Alexandre Petrovic in 1970s which stated that craniofacial growth happened because of growth signals and feedback mechanisms. Petrovich theorized a Cybernetic Model for the Servosystem Theory. This theory states that occlusion provides a constantly changing input which influences the horizontally regulated growth of the midface and anterior cranial base. This midface growth then serves as a rate limiting factor for the growth of the mandible.

Dentition Mesocarnivore cheek teeth are heterodont and their different shapes reflect distinct functions. Incisors and canines are used to apprehend food and kill prey, pointed premolars pierce and hold prey, and molars are involved in both slicing and crushing functions. The slicing function of the molars is produced by occlusion between the carnassials, the lower first molar, and the upper fourth premolar. Mesocarnivores are first represented by the Miacidae.

Also according to Yahnke (1995; et al.1996) the present restricted range is a relic of a much wider former range. Zoologists noted the distinctiveness in the ecological niche, appearance, and behavior of this species. Darwin's fox is differentiated from the gray fox in being darker; having shorter legs; a broader, shorter skull; smaller auditory bullae; a more robust dentition; and a different jaw shape and style of premolar occlusion.

Intrauterine hypoxia (also known as fetal hypoxia) occurs when the fetus is deprived of an adequate supply of oxygen. It may be due to a variety of reasons such as prolapse or occlusion of the umbilical cord, placental infarction and maternal smoking. Intrauterine growth restriction may cause or be the result of hypoxia. Intrauterine hypoxia can cause cellular damage that occurs within the central nervous system (the brain and spinal cord).

Mayfield told the surgeon to contact the props man on the set of the TV show, Ben Casey, where their use had been featured in a recent episode. Modifications and improvements to the Mayfield clip followed. Charles Drake worked with Mayfield to develop a fenestrated clip through which the posterior cerebral artery could pass, thus facilitating occlusion of basilar terminus aneurysms. That clip would be called the Drake fenestrated clip.

CRAO can be classified based on it pathogenesis, as arteritic versus non-arteritic. Non-arteritic CRAO is most commonly caused by an embolus and occlusion at the narrowest part of the carotid retinal artery due to plaques in the carotid artery resulting in carotid retinal artery atherosclerosis. Further causes of non-arteritic CRAO may include vasculitis and chronic systemic autoimmune diseases. Arteritic CRAO is most commonly caused by giant cell arteritis.

Hz2V026 is most similar to GbNV pif-2 and Autographa californica multiple nucleopolyhedrovirus (AcMPV), and it may form disulfide bonds and be a structural component of the occlusion-derived virus envelope. Hz2V053 is a homologue of baculovirus pif-3 and GbNV pif-3. It contains an N-terminal transmembrane domain. Hz2V082 is a homologue of the GbNV pif-1 gene and is very similar to the Spodoptera litteroralis NPV (SlNPV).

British Medical Journal 285: 972 only.. Arterial occlusion may be due to thrombi, amniotic fragments or air embolism. Postpartum cerebral angiopathy is a transitory arterial spasm of medium caliber cerebral arteries; it was first described in cocaine and amphetamine addicts, but can also complicate ergot and bromocriptine prescribed to inhibit lactation. Subarachnoid haemorrhage can occur after miscarriage or childbirth. All these usually present with neurological symptoms, and occasionally with delirium.

The Model-based gait recognition approach considers a human subject as an articulated object, represented by various body poses. Professor Venetsanopoulos proposed a full-body, layered deformable model (LDM) inspired by the manually labeled body-part-level silhouettes. The LDM has a layered structure to model self-occlusion between body parts and it is deformable, so simple limb deformation is taken into consideration. In addition, it also models shoulder swing.

Idiopathic diseases are those that occur spontaneously without a known cause. Moyamoya is an example of an idiopathic cerebrovascular disorder that results in narrowing and occlusion of intracranial blood vessels. The most common presentation is stroke or transient ischemic attack, but cognitive decline within children may also be a presenting symptom. The disease may begin to show symptoms beginning in adolescence, but some may not have symptoms until adulthood.

Ion pumps no longer transport Ca2+ out of cell, this triggers release of glutamate, which in turn allows calcium into cell walls. In the end the apoptosis pathway is initiated and cell death occurs. There are several arteries that supply oxygen to different areas of the brain, and damage or occlusion of any of them can result in stroke. The carotid arteries cover the majority of the cerebrum.

Natural antibodies recognize these clusters on senescent erythrocytes. Protection by HbAS involves the enhancement of not only innate but also of acquired immunity to the parasite. Prematurely denatured sickle hemoglobin results in an upregulation of natural antibodies which control erythrocyte adhesion in both malaria and sickle cell disease. Targeting the stimuli that lead to endothelial activation will constitute a promising therapeutic strategy to inhibit sickle red cell adhesion and vaso-occlusion.

A cerebrovascular accident (stroke) can lead to the thalamic pain syndrome, which involves a one-sided burning or aching sensation often accompanied by mood swings. Bilateral ischemia of the area supplied by the paramedian artery can cause serious problems including akinetic mutism, and be accompanied by oculomotor problems. A related concept is thalamocortical dysrhythmia. The occlusion of the artery of Percheron can lead to a bilateral thalamus infarction.

It is characterized by three overlapping stages of venous inflammation (vasculitis), occlusion, and retinal neovascularization. The exact mechanism is not known but it has been preposed that T-cells play a role in the inflammation that begins in the eye. Vascular endothelial growth factor (VEGF) is found in an increased amount in patients with ED and explains the increase in vascularization within the eye. Neovascularization is stimulated by hypoxia or ischemia.

More involved Orthognathic Surgery may be required in cases where the chin is small and a significant overbite co-exist. While the procedures above may improve the cosmetic appearance of the chin, they will not improve dental occlusion. Mandibular advancement surgery can be used to correct the alignment of the teeth and improve the projection of the chin. Non-surgical chin augmentation - Another method of chin augmentation uses an injectable filler.

Catastrophic antiphospholipid syndrome (CAPS), also known as Asherson's syndrome, is an acute and complex biological process that leads to occlusion of small vessels of various organs. It was first described by Ronald Asherson in 1992. The syndrome exhibits thrombotic microangiopathy, multiple organ thrombosis, and in some cases tissue necrosis and is considered an extreme or catastrophic variant of the antiphospholipid syndrome. CAPS has a mortality rate of about 50%.

Mutually protected occlusion - Posterior disocclusion of teeth as the mandible is protruded (Institute of Dentistry Aberdeen University) The Journal of Prosthetic Dentistry (2017) defines mutually protected occlusion as ‘an occlusal scheme in which the posterior teeth prevent excessive contact of the anterior teeth in maximal intercuspal position, and the anterior teeth disengage the posterior teeth in all mandibular excursive movements’ In eccentric movements, damaging forces are applied to the posterior teeth and the anteriors are best suited to receiving these. Therefore during protrusive movements, the contact or guidance of the anteriors should be adequate to disocclude and protect the posterior teeth. In contrast, the posterior teeth are more suited to accept the forces that are applied during closure of the mandible. This is because the posteriors are positioned so the forces are applied directly along the long axis of the tooth and are able to dissipate them efficiently whereas the anteriors cannot accept these heavy forces as well due to their labial positioning and angulation.

In addition, the devices' unique design features may help reduce the risk of bacterial contamination: The company launched the Neutron catheter patency device, a needle-free infusion access device that is the first and only device the U.S. Food and Drug Administration (FDA) cleared to claim the ability to eliminate all types of reflux into a catheter. Blood reflux, or blood backing up into the catheter, has been shown to cause catheter occlusion. Blood reflux can lead to an intraluminal thrombus, which may result in an inability to infuse IV fluids/medications, an inability to withdraw blood, and an increased risk of infection The Neutron device eliminates reflux caused by external factors such as connecting and disconnecting a luer, and is the only device that can eliminate reflux caused by changes to a patients vascular pressure changes caused by coughing, sneezing, crying or vomiting. In clinical use, Neutron has been shown to reduce the instance of catheter occlusion by 50%.

This allows study of changes over time in 3D, or so-called 4D microscopy. After the image acquisition the different image stacks are registered to form one single 3D dataset. Multiple views of the sample can be collected, either by interchanging the roles of the objectives or by rotating the sample. Having multiple views can yield more information than a single stack; for example occlusion of some parts of the sample may be overcome.

Myopia, with or without astigmatism, is the most common eye condition in horses. Several types of occlusion myopia have been recorded in tree shrews, macaques, cats and rats, deciphered from several animal-inducing myopia models. Preliminary laboratory investigations using retinoscopy of 240 dogs found myopic problems with varying degrees of refraction errors depending on the breed. In cases involving German Shepherds, Rottweilers and Miniature horses, the refraction errors were indicative of myopia.

For example, noise travels freely through an open door but is blocked when the door is closed. The team used the new "occlusion" feature in EAX 2.0 to make Thief IIs sound environment more realistic and to allow the player to listen through doors. The game features more sound effects, music and speech than the original Thief. Thief IIs score, as with that of its predecessor, was designed to "blur ambient [sound] and music" together.

The mandibular first molar is the tooth located distally from both the mandibular second premolars of the mouth but mesially from both mandibular second molars. It is located on the mandibular arch of the mouth, and generally opposes the maxillary first molars and the maxillary 2nd premolar. This arrangement is known as Class I occlusion. There are usually five well-developed cusps on mandibular first molars: two on the buccal, two lingual, and one distal.

Assuming specificity to that one sequence and that the sequence of the genome is random, 18 bp is long enough to be unique in all known genomes Indeed, the spacing between subsites becomes part of the target sequence due to restrictions in the flexibility of the protein which can be controlled. Targeting sites as small as 9 bp provides some degree of specificity, almost certainly attributable in some part to chromatin occlusion.

He particularly looks forward to the hanging of his cousin Paris, whose leg wound appears minor. But the trauma of the gunshot has triggered "some occlusion of the blood," a pulmonary embolism that Paris recognises as fatal. Paris dies before the ship can reach St. Augustine, and Erasmus comes to the realisation that Paris did not lift him clear of the dam to cheat him of victory, but to save him from defeat.

Wiedemann has published more than 400 peer reviewed papers and eight books. His clinical papers focus on proliferative vitreoretinopathy (PVR), age-related macular degeneration (AMD), central retinal vein occlusion (CRVO), myopia and diabetic retinopathy. His basic science papers concern the role of retinal pigment epithelial (RPE) or Muller cells in retinal diseases. As the co-editor of the Ryan's RETINA 5th edition, the standard reference for retinologist worldwide, he was responsible for the surgical section.

Zinc phosphate is the oldest material available and has been used in dentistry for more than a century. The introduction of adhesive resin systems made a wide range of dental materials available as luting agents. The choice of luting agent is dependent on clinical factors including dental occlusion, tooth preparation, adequate moisture control, core material, supporting tooth structure, tooth location, etc. Research has determined that no single luting agent is ideal for all applications.

In small vessels, the most common cause is lipohyalinosis. Lipohyalinosis is when high blood pressure and aging causes a build-up of fatty hyaline matter in blood vessels. Atheroma formation can also cause small vessel thrombotic ischemic stroke. Occlusion of blood flow generates a depolarization of neurons that generate a wave called spreading depolarization, that moves from the affected core to the penumbra and healthy brain producing further depolarization, neuronal dead and neurologic symptoms.

A complex approach to non-surgical management of strabismus (wandering eye), amblyopia (lazy eye) and eye movement disorders may include a variety of vision therapy methods, primarily directed at the abnormal retinal correspondence management such as eye occlusion with an eye patch, binocular vision training using a haploscope and many others. The orthoptic therapy can be used either before or after the surgical treatment, as it is prescribed by an eye care specialist.

Jaw abnormalities are commonly treated with combined surgical (orthognathic surgery) and orthodontic treatment. The procedure is carried out by oral and maxillofacial surgeons and orthodontists in close collaboration. In most cases, the orthodontist will first align the teeth with braces or other appliances, which may worsen the occlusion until after the surgery. This is carried out to show the full degree of abnormality, and to create sufficient space for full correction in the bones.

Further towards the inner side, a crest, the entocristid, rims the talonid basin; on m1, it is swollen and on m2, it contains two small cuspules, but a distinct entoconid cusp is absent. This entocristid is continuous with the lingual cingulum. Wear facets are areas of a tooth that show evidence of contact with a tooth in the opposing jaw when the teeth are brought together (known as occlusion).Luo et al.

In 1962 Professor Askenasy, together with Professor Ephraim Frei from the Weizmann Institute, developed a magnetic catheter (POD) for intra-arterial endovascular navigation to brain circulation. This approach was an early development for endovascular therapy and treatment of occlusion, cerebral arterial aneurysms, thrombolysis, and arterial venous malformations. Professor Askenasy researched the interaction between the 100 watt CO2 laser and brain tissue. This served as an analysis for its use to remove brain tumors.

After the 1975 general election, in which Labor was heavily defeated, Connor was unexpectedly re-elected to the Opposition front bench. This was seen as a gesture of Labor defiance to the Murdoch press, which had played a leading role in bringing down Whitlam's government. Connor's wife died in April 1977 and he died suddenly in Canberra of a coronary occlusion in August of that year. He was survived by their three sons.

Ankylosis and primary fail of eruption (PFE) give similar symptoms, since in both cases a targeted tooth is positioned not vertically and unresponsive to orthodontic force applied. Therefore, ankylosis should be differentiated from primary fail of eruption. For an ankylosed molar, distal teeth can respond to orthodontic force normally and thus can be used as substitute if the ankylosed tooth is extracted. Surgical luxation is sometimes used to break the ankylosis bridge to restore occlusion.

Inertial motion capture systems are able to capture finger motions reading the rotation of each finger segment in 3D space. Applying these rotations to kinematic chain, the whole human hand can be tracked in real time, without occlusion and wireless. Hand inertial motion capture systems, like for example Synertial mocap gloves, are using tiny IMU based sensors, located on each finger segment. For most precise capture, at least 16 sensors have to be used.

The intestine becomes distended due to the trapped fluid and gas production from bacteria. It is this distension, and subsequent activation of stretch receptors within the intestinal wall, that leads to the associated pain. With progressive distension of the intestinal wall, there is occlusion of blood vessels, firstly the less rigid veins, then arteries. This impairment of blood supply leads to hyperemia and congestion, and ultimately to ischaemic necrosis and cellular death.

Though highly unusual and possibly indicating atypical occlusion patterns, volaticotherian molars are thought to have had a shearing motion as in other eutriconodonts. Combined with long canines, this seems to indicate that, like their relatives, they were probably carnivorous. Ichthyoconodon was fairly large by Mesozoic mammal standards, and were probably capable of tackling vertebrate prey. In a study about Mesozoic mammal diets Argentoconodon ranks among carnivorous species, while Volaticotherium ranks among insectivorous taxa.

This option also negates the risks and costs that comes with prosthodontic treatment and the impression that there is no missing tooth. Some factors need to be considered when making a decision whether to undergo space closure. These include facial profile, size and dimension of canine, the shade of colour of the teeth and the gingival contour and height. Group function occlusion is usually present as a result of the mesial movement of the canine.

Narrowing of the coronary artery, which occurs as a result of the healing process of the vessel wall, often leads to significant obstruction of the blood vessel and the heart not receiving enough blood and oxygen. This can eventually lead to heart muscle tissue death, i.e., myocardial infarction (MI). MI caused by thrombotic occlusion in an aneurysmal, stenotic, or both aneurysmal and stenotic coronary artery is the main cause of death from Kawasaki disease.

The task becomes significantly complicated by factors such as background clutter, occlusion, and variations in viewpoint, illumination, and scale. Ideally, we would like the particular representation we choose to be robust to as many of these factors as possible. In category-level recognition, the problem is even more challenging because of the fundamental problem of intra-class variation. Even if two objects belong to the same visual category, their appearances may be significantly different.

In addition, animals may block one another in the camera views, a problem known as occlusion. Once the location of each animal at each point in time is known, various parameters describing the animal group can be extracted. These parameters include: Density: The density of an animal aggregation is the number of animals divided by the volume (or area) occupied by the aggregation. Density may not be a constant throughout the group.

The procedure is performed in general anesthesia. It is useful to place pulse oximeter probes on both hands and one foot so that test occlusion of one arch or its branches will allow confirmation of the anatomy. In addition blood pressure cuffs should also be placed on one leg and both arms to confirm the absence of a pressure gradient when the intended point of division of the lesser arch is temporarily occluded with forceps.

Cystoid macular edema (CME). There are intraretinal cystoid spaces Cystoid macular edema (CME) involves fluid accumulation in the outer plexiform layer secondary to abnormal perifoveal retinal capillary permeability. The edema is termed "cystoid" as it appears cystic; however, lacking an epithelial coating, it is not truly cystic. The cause for CME can be remembered with the mnemonic "DEPRIVEN" (diabetes, epinepherine, pars planitis, retinitis pigmentosa, Irvine-Gass syndrome, venous occlusion, E2-prostaglandin analogues, nicotinic acid/niacin).

The game's renderer engine employs more advanced graphic technologies than was possible in the previous console generation, including parallax mapping, ambient occlusion, subsurface scattering, and high dynamic range. The soundtrack of the game was primarily composed by David Clynick, who worked with Grant Kirkhope on the original Nintendo 64 game's score. New York based group MorissonPoe contributed two songs to the score, while DJs Kepi and Kat composed the game's nightclub theme.

Shortly after stepping down from the presidency in 2000, Lee had coronary artery bypass surgery. In late 2011, he underwent surgery to remove stage II colon adenocarcinoma, the most common form of colon cancer. Two years later, he had a stent implanted in his vertebral artery following an occlusion. Lee was sent to Taipei Veterans General Hospital in November 2015 after experiencing numbness in his right hand, and later diagnosed with a minor stroke.

The labial fricatives often—perhaps usually—have lateral airflow, as occlusion between the teeth and lips blocks the airflow in the center, but nonetheless they are not considered lateral consonants because no language makes a distinction between the two. In some languages, the centrality of a phoneme may be indeterminate. In Japanese, for example, there is a liquid phoneme , which may be either central or lateral, resulting in /ro/ produced as either or .

Ray tracing is capable of simulating a variety of optical effects, such as reflection and refraction, scattering, and dispersion phenomena (such as chromatic aberration). Path tracing is a form of ray tracing that can produce soft shadows, depth of field, motion blur, caustics, ambient occlusion, and indirect lighting. Path tracing is an unbiased rendering method, but a large number of rays must be traced to obtain high quality reference images without noisy artifacts.

A containment event tests the infant's recognition that an object that is bigger than a container cannot fit completely into that container. Elizabeth Spelke, one of the psychologists who founded the naïve physics movement, identified the continuity principle, which conveys an understanding that objects exist continuously in time and space. Both occlusion and containment experiments hinge on the continuity principle. In the experiment, the infant is shown a tall cylinder and a tall cylindrical container.

In a geminate or long consonant, the occlusion lasts longer than in simple consonants. In languages where plosives are only distinguished by length (e.g., Arabic, Ilwana, Icelandic), the long plosives may be held up to three times as long as the short plosives. Italian is well known for its geminate plosives, as the double t in the name Vittoria takes just as long to say as the ct does in English Victoria.

Lutheran blood group glycoprotein is a member of the immunoglobulin superfamily and a receptor for the extracellular matrix protein, laminin. The protein contains five, N-terminus, extracellular immunoglobulin domains, a single transmembrane domain, and a short, C-terminal cytoplasmic tail. This protein may play a role in epithelial cell cancer and in vaso-occlusion of red blood cells in sickle cell disease. Two transcript variants encoding different isoforms have been found for this gene.

According to Pruzanksky's classification, if the patient has moderate to severe symptoms, then surgery is preferred. If patient has mild symptoms, then a functional appliance is generally used. According to Dr. Harry Pepe, a pediatrician from Hollywood, Fl, the goal of treatment in hemifacial microsomia is to elongate the deficient jaw bone to restore facial symmetry and correct the slanting bite (occlusion). Patients can also benefit from a Bone Anchored Hearing Aid (BAHA).

Models of human teeth in maximum intercuspation. The models are transparent to allow the viewer to perceive the roots of the teeth as they reside naturally within the alveolar bone. In dentistry, maximum intercuspation refers to the occlusal position of the mandible in which the cusps of the teeth of both arches fully interpose themselves with the cusps of the teeth of the opposing arch. This position used to be referred to as centric occlusion.

Sullivan completed a doctor of science from Harvard T.H. Chan School of Public Health in 1997. She conducted a dissertation in the laboratory of Joseph Sodroski, where her work demonstrated that primary HIV isolates exhibit resistance to antibody neutralization due to occlusion of the coreceptor binding site on gp120. Following her work on HIV, Sullivan pursued postdoctoral training under the guidance of Gary Nabel, studying the mechanisms of Ebola virus pathogenesis and immune protection.

Splenic sequestration crisis (SSC) is a life-threatening illness common in pediatric patients with homozygous sickle cell disease and beta thalassemia. Up to 30% of these children may develop SSC with a mortality rate of up to 15%. This crisis occurs when splenic vaso-occlusion causes a large percentage of total blood volume to become trapped within the spleen. Clinical signs include severe, rapid drop in hemoglobin leading to hypovolemic shock and death.

However, when the opening is obstructed due to inflammation, polyps, mucosal thickening, anatomical abnormalities, or other lesions, pressure equilibration is impossible. Squeeze is produced on descent when trapped air in the sinuses contracts and produces negative pressure. The pressure differentials are directed to the center of the sinuses producing mucosal edema, transudation, and mucosal-or submucosal-hematoma, leading to further occlusion of the sinus ostium. The sinus will fill with fluid or blood unless the pressure differential is neutralized.

When the intracellular temperature reaches 60 degrees C, instantaneous cell death occurs. If tissue is heated to 60–99 degrees C, the simultaneous processes of tissue desiccation (dehydration) and protein coagulation occur. If the intracellular temperature rapidly reaches 100 degrees C, the intracellular contents undergo a liquid to gas conversion, massive volumetric expansion, and resulting explosive vaporization. Appropriately applied with electrosurgical forceps, desiccation and coagulation result in the occlusion of blood vessels and halting of bleeding.

A basic cladogram of the origin of mammals. Important developments in the transition from reptile to mammal were the evolution of warm-bloodedness, of molar occlusion, of the three-ossicle middle ear, of hair, and of mammary glands. By the end of the Triassic, there were many species that looked like modern mammals and, by the Middle Jurassic, the lineages leading to the three extant mammal groups -- the monotremes, the marsupials, and the placentals -- had diverged.

In all cases, soft shadows for static geometry are possible if simple occlusion tests (such as basic ray-tracing) are used to determine which lumels are visible to the light. However, the actual softness of the shadows is determined by how the engine interpolates the lumel data across a surface, and can result in a pixelated look if the lumels are too large. See texture filtering. Lightmaps can also be calculated in real-timeNovember 16, 2003.

Hypothenar hammer syndrome (HHS) is a vascular occlusion in humans in the region of the ulna. It is caused by repetitive trauma to the hand or wrist (such as that caused by the use of a hammer) by the vulnerable portion of the ulnar artery as it passes over the hamate bone, which may result in thrombosis, irregularity or aneurysm formation. HHS is a potentially curable cause of Raynaud's syndrome, distinct from hand–arm vibration syndrome.

Gosse died of a coronary occlusion at Maslin Beach on 31 December 1964, and was cremated. The Victoria Cross recipient Brigadier Sir John George Smyth wrote that Gosse "always lived right on top of the world, as though every day was his last". He is commemorated on the Returned and Services League Walls at the Centennial Park Cemetery in Pasadena, South Australia. His medal set is displayed in the Hall of Valour at the Australian War Memorial.

The antibacterial activity of rifamycins relies on the inhibition of bacterial DNA-dependent RNA synthesis. This is due to the high affinity of rifamycins for the prokaryotic RNA polymerase. The selectivity of the rifamycins depends on the fact that they have a very poor affinity for the analogous mammalian enzyme. Crystal structure data of the antibiotic bound to RNA polymerase indicates that rifamycin blocks synthesis by causing strong steric clashes with the growing oligonucleotide ("steric-occlusion" mechanism).

In 1983 the use of electrically induced thrombosis for intracranial aneurysms was described for the first time. A stainless steel electrode supplied a positive current to the aneurysm to stimulate electrothrombosis. Minimal occlusion was achieved, but the researchers discovered that the erosion of the electrode due to electrolysis would be useful as a detachment system. Detachable coils were constructed from a platinum coil soldered to a stainless steel delivery wire, first described in 1991 by Guglielmi et al.

Subdural empyema is a form of empyema – a collection of pus, in the subdural space. Bacterial or occasionally fungal infection of the skull bones or air sinuses can spread to the subdural space, producing a subdural empyema. The underlying arachnoid and subarachnoid spaces are usually unaffected, but a large subdural empyema may produce a mass effect. Further, a thrombophlebitis may develop in the bridging veins that cross the subdural space, resulting in venous occlusion and infarction of the brain.

|
An embolism is said to occur when the thrombus (blood clot) becomes a mobile embolus and migrates to another part of the body, interfering with blood circulation and hence impairing organ function downstream of the occlusion. This causes ischemia and often leads to ischemic necrosis of tissue. Most cases of venous thrombosis are due to acquired states (older age, surgery, cancer, immobility) or inherited thrombophilias (e.g., antiphospholipid syndrome, factor V Leiden, and various other genetic deficiencies or variants).
|
|
Permeability is the physical measure of the ability of a material to transmit fluids over time. To measure thrombus permeability, one needs to measure contrast flow through a clot over time and the pressure drop caused by the occlusion, which is commonly not possible in the acute management of a patient with acute ischemic stroke. Current standard diagnostic protocol for acute ischemic stroke only requires single-phase imaging, visualizing the thrombus at a snapshot in time.

On September 18, 2003, during Hurricane Isabel, Chalker passed out and was rushed to the hospital with a diagnosis of a coronary occlusion. He was later released, but was severely weakened. On December 6, 2004, he was again rushed to hospital with breathing problems and disorientation, and was diagnosed with congestive heart failure and a pneumothorax. Chalker was hospitalized in critical condition, then upgraded to stable condition on December 9, though he did not regain consciousness until December 15.

Treatment can be undertaken using orthodontic treatments using dental braces. While treatment is carried out, there is no evidence from clinical trials to recommend or discourage any type of orthodontic treatment in children. A 2018 Cochrane systematic review anticipated that the evidence base supporting treatment approaches is not likely to improve occlusion due to the low prevalence of the condition and the ethical difficulties in recruiting people to participate in a randomized controlled trials for treating this condition.

From there, Dunn oversaw an era of great success, underwritten by the extra finances gained from the move and the efforts of the coterie. Under his administration, the Tigers broke a 24-year premiership drought in 1967 and followed up with another triumph two years later. Unfortunately, Dunn's health then began to fail. He had battled diabetes since the early 1960s, and finally succumbed to a coronary occlusion on 26 August 1971 at his Metung holiday home.

Timely extractions are often the preferred treatment plan for first permanent molars that are severely affected and symptomatic. The facilitation of eruption of the second permanent molars to the space of the first permanent molar removes the burden of continuous restorative treatment. A favourable occlusion may be acquired following a well-planned treatment and this eliminates the need for fixed orthodontic appliances therapy. However, a comprehensive discussion of the possible need of orthodontic sequelae and treatment is important.

Tetrahydrocannabinol (THC), the active chemical substance in cannabis, also causes a nearly complete occlusion of salivation, known in colloquial terms as "cotton mouth". Moreover, 63% of the most commonly prescribed medications in the United States list dry mouth as a known side-effect. Radiation therapy of the head and neck may also damage the cells in salivary glands, somewhat increasing the likelihood of caries formation.Oral Complications of Chemotherapy and Head/Neck Radiation , hosted on the National Cancer Institute website.

Kaliseptine has been shown to reduce ion current through the KV1.2 K+ channel during depolarization. Since it has affinity for the DTXI receptor domain, kaliseptine may act on the channel in a similar manner as the agonist DTXI. Whether kaliseptine exerts its action by hindering conformational changes of the KV1.2 channel, is not certain. Evidence was provided that DTXI binds in close proximity to the external mouth of the channel, leading to occlusion of the pore.

The master casts are used to provide accurate information about the occlusion to the laboratory and construct the prosthesis. # Occlusal registration: An occlusal registration is needed when providing extensive bridgework to allow the opposing casts to be related accurately. This may not be necessary if only a small number of teeth are to be restored. # Temporary restoration: Temporary restorations should be fabricated if possible to protect and maintain the prepared teeth until placement of the final restoration.

Cox was found dead on February 15, 1973 in his Hollywood, California home; he was 48. According to an autopsy, Cox died of a heart attack caused by a coronary occlusion. Initial reports indicated that he wished to have no funeral and that his ashes would be scattered at sea. A later report indicated his ashes were put in with those of Brando and another close friend Sam Gilman and scattered in Death Valley and Tahiti.

The maxillary teeth are inset medially and project below the internal naris. There is also an occlusion between the vomerine teeth and dentary teeth with saddle-shaped vomers that overhang the dorsal side of the premaxillary symphysis. Looking at the spine, the length of the axis neural spine is greater than the length of axis centrum. It also has a craniocaudally narrow neural spine of the third cervical and a prominent midventral groove on the first two caudal centra.

It results in the occlusion of the catalytic site and full shutdown of kinase activity. This "closed" state can only be relieved if the autoinhibitory domain of Raf engages a partner competing with its own kinase domain, most importantly GTP-bound Ras. Activated small G-proteins can thus break up the intramolecular interactions: this results in a conformational change ("opening") of c-Raf necessary for kinase activation and substrate binding. 14-3-3 proteins also contribute to the autoinhibition.

A medical use for a sauna suit is in the treatment of psoriasis, an inflammation of the skin causing itchiness and discomfort. The symptoms of psoriasis can be relieved by use of ointments and by keeping the skin moist. The wearing of a sauna suit helps to retain skin moisture and to prevent the ointment from leaking out and staining other clothing, furniture or bedding. In medical literature, a sauna suit is also called an "occlusion suit".

Initial secretion of bradykinin post-natally causes constriction and eventual atrophy of the ductus arteriosus, forming the ligamentum arteriosum between the pulmonary trunk and aortic arch. It also plays a role in the constriction and eventual occlusion of a number of other fetal vessels, including the umbilical arteries and vein. The differential vasoconstriction of these fetal vessels compared to the vasodilator response of other vessels suggest that the walls of these fetal vessels are different than other vessels.

During a late model race on Easter Sunday, April 2, 1972, at Metrolina Fairgrounds in Charlotte, where he started the race despite reporting he was not feeling well, Thompson's car stopped on the track. He was found in his car not breathing, was revived and put into an ambulance, but he died on the way to the hospital, one day before his 46th birthday. The medical examiner said that he died of natural causes, an acute coronary occlusion.

Conditions which cause increased rouleaux formation include infections, inflammatory and connective tissue disorders, and cancers (most common in multiple myeloma). It also occurs in diabetes mellitus and is one of the causative factors for microvascular occlusion in diabetic retinopathy. Erythrocyte sedimentation rate closely reflects the extent of aggregation, therefore can be used as a measure of aggregation. Erythrocyte aggregation can also be quantitated by monitoring optical properties of blood during the time course of aggregation process.

Where a patient tends to consistently fixate with one eye and squint with the other, the eye that squints is likely to develop some amblyopia. Someone whose squint alternates is very unlikely to develop amblyopia because both eyes will receive equal visual stimulation. It is possible to encourage alternation through the use of occlusion or patching of the 'dominant' or 'fixating' eye to promote the use of the other. Esotropia is a highly prevalent congenital condition.

She showed that the antiviral drug amantadine inhibits proton conduction by direct occlusion of the channel pore. She determined the cholesterol-binding structure of the M2 protein, which sheds light on how cholesterol mediates M2's membrane scission function. In 2020 she determined the first phospholipid-bound structures of the influenza B M2 protein in both its closed and open states. The 1.5 Å structures gave insight into differences in the activation mechanism of BM2 compared to AM2.

Due to the branches of the aorta that supply the anterior spinal artery, the most common causes are insufficiencies within the aorta. These include aortic aneurysms, dissections, direct trauma to the aorta, surgeries, and atherosclerosis. Acute disc herniation, cervical spondylosis, kyphoscoliosis, damage to the spinal column and neoplasia all could result in ischemia from anterior spinal artery occlusion leading to anterior cord syndrome. Other causes include vasculitis, polycythemia, sickle cell disease, decompression sickness, and collagen and elastin disorders.

In Mudbox 2009 3D painting and texturing features were introduced to allow artists to paint directly on their models in 3D. In addition, features to display the model with depth of field and ambient occlusion were added for the release. In Mudbox 2010, an application programming interface (API) was introduced via a software development kit (SDK). In addition, functionality to improve file interoperability with other 3D applications (Autodesk Maya, 3ds Max etc.) was added via the FBX file format.

Subclavian steal syndrome arises from retrograde (reversed) flow of blood in the vertebral artery or the internal thoracic artery, due to a proximal stenosis (narrowing) and/or occlusion of the subclavian artery. Symptoms such as syncope, lightheadedness, and paresthesias occur while exercising the arm on the affected side (most commonly the left). Aortic dissection (a tear in the aorta) and cardiomyopathy can also result in syncope. Various medications, such as beta blockers, may cause bradycardia induced syncope.

Maxillary and mandibular record bases with notched wax rims. Wax rims are devices that are used in dentistry to help in the fabrication of removable prostheses, such as complete and partial dentures. When placed in the mouth, wax rims allow the dentist to record a measured vertical dimension of occlusion (VDO) because the patient will be unable to close further than the wax will allow. The wax is built up or removed until the appropriate VDO has been established.

If an alpha channel is used in an image, there are two common representations that are available: straight (unassociated) alpha, and premultiplied (associated) alpha. With straight alpha, the RGB components represent the color of the object or pixel, disregarding its opacity. With premultiplied alpha, the RGB components represent the emission of the object or pixel, and the alpha represents the occlusion. A more obvious advantage of this is that, in certain situations, it can save a subsequent multiplication (e.g.

URL last accessed March 1, 2006. Even though the mechanism of strangulation is similar, it is usually distinguished from hanging by the strangling force being something other than the person's own bodyweight. Incomplete occlusion of the carotid arteries is expected and, in cases of homicide, the victim may struggle for a period of time, with unconsciousness typically occurring in 10 to 15 seconds. Cases of ligature strangulation generally involve homicides of women, children, and the elderly,.

On January 31, 1956, Governor Paul L. Patterson, who was elected in the 1954 gubernatorial election, died in office of a coronary occlusion. Patterson's death elevated Oregon State Senate President Elmo Smith to governor and a special election for November was called to fill the position for the final two years of Patterson's term. The succession law was changed in 1972 so that the Oregon Secretary of State is first in line to succeed the governor.

Thus finding their occlusion in centric relation (CR) is key in diagnosis. For anterior crossbite, if their CO matches their CR then the patient truly has a skeletal component to their crossbite. If the CR shows a less severe class 3 malocclusion or teeth not in anterior crossbite, this may mean that their anterior crossbite results due to dental interferences. Goal to treat unilateral crossbites should definitely include removal of occlusal interferences and elimination of the functional shift.

VPI can cause hypernasality (excessive nasal resonance), hyponasality (reduced nasal resonance), or a mixed nasal resonance, which is when hypernasality and hyponasality occur simultaneously. In addition, CLP may cause abnormal positioning of individual teeth, which can in turn affect the patient's ability to make certain sounds when speaking such as the "f" or "v" sound and can also result in a lisp. The changes in speech may also be a manifestation on CLP's effects on the patient's occlusion.

Generally, complete denture occlusion should be influenced by patient satisfaction following a paternalistic shift in the provision of dental care. Besford et al. suggests that provision that complete denture anterior disclusion should be driven by patient's aesthetic preferences incorporating an overjet. He describes that there should be a shift from a standardized visual aesthetic and instead the appearance of the complete denture should enable patients to 'regain their own personal imperfect dental identity', disregarding any occlusal scheme.

Coronary CT angiography (CTA) is the use of computed tomography (CT) angiography to assess the coronary arteries of the heart. The subject receives an intravenous injection of radiocontrast and then the heart is scanned using a high speed CT scanner, allowing physicians to assess the extent of occlusion in the coronary arteries, usually in order to diagnose coronary artery disease. CTA is superior to coronary CT calcium scan in determining the risk of Major Adverse Cardiac Events (MACE).

Cappon married Henrietta Van Putten of Holland, Michigan, and they had their first child, Franklin C. Cappon, Jr., in 1925. They also had a daughter, Mary L. Cappon. In January 1961, Cappon suffered a mild heart attack, and he was hospitalized again for two weeks in the summer of 1961 with an occlusion in an artery of his left arm. Cappon returned to work at Princeton despite the stress that coaching would put on his heart.

The problem of motion estimation generalizes to binocular vision when we consider occlusion or motion perception at relatively large distances, where binocular disparity is a poor cue to depth. This fundamental difficulty is referred to as the inverse problem. Nonetheless, some humans do perceive motion in depth. There are indications that the brain uses various cues, in particular temporal changes in disparity as well as monocular velocity ratios, for producing a sensation of motion in depth.

Arterial embolism can cause occlusion in any part of the body. It is a major cause of infarction (tissue death from blockage of the blood supply). An embolus lodging in the brain from either the heart or a carotid artery will most likely be the cause of a stroke due to ischemia. An arterial embolus might originate in the heart (from a thrombus in the left atrium, following atrial fibrillation or be a septic embolus resulting from endocarditis).

In October 2019, Veriff released a near-field communication (NFC) verification tool to validate biometric documents. If a device has an integrated reader, the cross-platform tool reads data directly from the chip, detecting fraud attempts. In March 2020, Veriff launched a new Assisted Image Capture (AIC) service as a separate solution. AIC gives customers real-time feedback to avoid the most common mistakes during the identification process, like blurriness, glare, facial occlusion or damaged ID documents.

The creation of this interocclusal space will significantly reduce the amount of tooth preparation required, especially on the already compromised palatal surfaces of the maxillary anterior teeth. Adaptation occurs over a period of some months: compensatory eruption of the posterior teeth will occur, together with some intrusion of the anterior teeth and potential growth of the alveolar bone. This will allow the posterior occlusion to reestablish at the new increased OVD, stabilizing the increased interocclusal space.

Malocclusion is the imperfect positioning of the teeth when the jaw is closed. In dogs and cats with normal occlusion, the upper incisors rest in front of the lower incisors, the lower canines fit in the diastema between the upper canine and third incisor, the upper first premolars fit behind the lower first premolars, and the upper fourth premolars overlap the lower first molars. Any deviations are known as malocclusions, and they are separated by class.

Similarly, vessels and organs perfused from the true lumen but distal to the dissection may be perfused to varying degrees. In the above example, if the aortic dissection extended from proximal to the left subclavian artery takeoff to the mid descending aorta, the common iliac arteries would be perfused from the true lumen distal to the dissection but would be at risk for malperfusion due to occlusion of the true lumen of the aorta by the false lumen.

Predator in 2010 and Killzone 3 in 2011 also incorporated stealth elements. The 2012 game Dishonored tried to incorporate stealth elements that were influenced by Thief, such as the importance of lighting and shadows. The developers later abandoned that system citing realism as a factor. The game instead relies on a system of "occlusion-based" stealth, using the vision cones of the enemies, obstacles, and special abilities which determines whether or not the character is visible.

Given its dental morphology (i.e., the upper and lower molar cusps and crests that facilitate a combination of puncturing and shearing during occlusion), it has been inferred that Sivaladapis was well-adapted to a highly folivorous diet of fibrous leaves. Moreover, the absence of the hypocone suggests that grinding was not a functional priority for Sivaladapis. Additionally, Sivaladapis fossils have been recovered in association with a gibbon-sized hominoid, suggesting the taxa inhabited a forest community.

All dinocephalians are distinguished by the interlocking incisor (front) teeth. Correlated features are the distinctly downturned facial region, a deep temporal region, and forwardly rotated suspensorium. Shearing contact between the upper and lower teeth (allowing food to be more easily sliced into small bits for digestion) is achieved through keeping a fixed quadrate and a hinge- like movement at the jaw articulation. The lower teeth are inclined forward, and occlusion is achieved by the interlocking of the incisors.

Journal of Neuroscience 63: 131-149, 1990. This dominance does have limitations, however; in 1985, Eric Knudsen and Phyllis Knudsen conducted a study which showed that vision can alter the magnitude but not the sign of an auditory error.Knudsen, E.I. and Knudsen, P.F. “Vision guides the adjustment of auditory localization in young barn owls.” Science 230: 545-548, 1985. While monaural occlusion and visual displacement both alter the associations between sensory cues and corresponding spatial locations, there are significant differences in the mechanisms at work: “The task under [the conditions of monaural occlusion] is to use vision[…]to assign abnormal combinations of cue values to appropriate locations in space. In contrast, prisms cause a relatively coherent displacement of visual space while leaving auditory cues essentially unchanged. The task under these conditions is to assign normal ranges and combinations of cue values to abnormal locations in space”.Knudsen, E.I. and Knudsen, P.F. “Sensitive and critical periods for visual calibration of sound localization by barn owls” (230).

Cryonectes is a moderate-sized pliosaurid, as its skull has a length of . The specimen when discovered was prepared first with acid, which damaged some parts, especially the teeth, which are now broken and lack enamel. The complete mandible and the skull are in occlusion with teeth in situ and one separated and almost complete tooth is also known. The premaxillae and maxillae are partially preserved and the most important part of the palate is preserved separate from the skull.

Since the device is placed in the femoral artery and aorta it could provoke ischemia, and compartment syndrome. The leg is at highest risk of becoming ischemic if the femoral artery it is supplied by becomes obstructed. Placing the balloon too distal from the aortic arch may induce occlusion of the renal artery and subsequent kidney failure. Other possible complications are cerebral embolism during insertion, infection, dissection of the aorta or iliac artery, perforation of the artery and bleeding in the mediastinum.

Durham, NC: UHMS; 2009. When used as an adjunctive therapy, the edema reducing properties of HBO, along with down regulation of inflammatory cytokines may contribute to the improvement in vision. Prevention of vision loss requires that certain conditions be met: the treatment be started before irreversible damage has occurred (over 24 hours), the occlusion must not also occur at the ophthalmic artery, and treatment must continue until the inner layers of the retina are again oxygenated by the retinal arteries.

In hypertrophic cardiomyopathy, there is narrowing of the left ventricular outflow tract (LVOT) due to hypertrophy of the interventricular septum. During systole, the narrowing of the LVOT creates a more negative pressure due to the Venturi effect and sucks in the anterior mitral valve leaflet. This creates a transient occlusion of the LVOT, causing a midsystolic dip in the aortic waveform. Towards the end of systole, the ventricle is able to overcome the obstruction to cause the second rise in the aortic waveform.

Occlusal adjustment Occlusal adjustment is the process of selectively modifying occlusal surfaces of teeth through grinding to eliminate disharmonious occlusion between upper and lower teeth. Occlusal adjustment is only indicated when mobility is associated with periodontal ligament widening. Occlusal adjustments will be unsuccessful if the mobility is caused by other aetiology such as loss of periodontal support or pathology. Splinting This is the procedure of increasing resistance of tooth to an applied force by fixing it to a neighbouring tooth/ teeth.

In this advanced format, two more planes are added to the original 2D image and its depth map for each frame: the background areas covered by foreground objects and their respective depth map. So, each frame in the Declipse format is described with an image containing four parts, or quadrants. This extension improves potential visual quality by providing data for more correct and precise filling of the uncovered occlusion areas created by shifting foreground objects during the multiview generation process.

Warner died on July 25, 1958 from a cerebral occlusion. Some people close to Harry, however, believed he died of a broken heart; Harry's wife Rea even stated, after Harry's funeral took place, that "he didn't die, Jack killed him." He was entombed at Home of Peace Cemetery in East Los Angeles, California. He left an estate valued at $6,000,000 with 50% bequeathed to his wife and 25% to each of his daughters, Doris and Betty (married to producer Milton Sperling).

The game used a heavily modified version of Valve's Source as its game engine. Many improvements were made to the engine's aspects such as physically based rendering, a texture streaming system developed in house, high dynamic range and depth of field. The team also made changes to the audio, such as introducing sound occlusion and reverberation. According to John Haggerty, senior software engineer, the team broke part of the engine's code for level progression and saves when they were making the first game.

These crystals cause an inflammatory response and can lead to the occlusion of smaller vessels. Further complications like secondary infections and necrosis can develop from this and can be fatal for some, making the monitoring of blood calcium and phosphate levels necessary. Conditions due to bone loss such as osteopenia and osteoporosis are common in tertiary hyperparathyroidism along with pathologic fractures. Pseudoclubbing of the digits can also be indicative of a severe tertiary hyperparathyroidism due to excess resorption at the distal phalanges.

A systematic review on the treatment need for back jaw spaces without any teeth found that overeruption was limited to 2 mm for most studies reviewed. The authors of the review also noted the low quality of evidence and concluded that tooth replacement is not recommended as the chief therapy. Overeruption can cause interferences in the occlusion and difficulty when constructing dentures. The alveolar bone typically overgrows, but root surfaces can be exposed to the oral environment increasing likelihood of dental caries.

Preoperative imaging or an ultrasound probe may be used to help identify aortic calcifications that could potentially become dislodged and cause an occlusion or stroke. Once the cannulation site has been deemed safe, two concentric, diamond-shaped pursestring sutures are placed in the distal ascending aorta. A stab incision with a scalpel is made within the pursestrings and the arterial cannula is passed through the incision. It is important the cannula is passed perpendicular to the aorta to avoid creating an aortic dissection.

Associations of the disease with such entities as multiple sclerosis, sarcoidosis, or inflammatory bowel disease suggest an autoimmune component in at least a subset of patients. The clustering of familial cases has led to the investigation of human leukocyte antigen (HLA) associations. The inciting event appears to be peripheral retinal perivasculitis and vascular occlusion leading to ocular inflammation, vitritis and snowbank formation. The etiology of the antigenic stimulus is not clear and may be either vitreal or perivascular in nature.

Metzinger compensates for the missing spatiality in his two-dimensional representation by giving other cues for depth, in addition to relative size: shading and shadows, source of light, occlusion (e.g., the stage or table upon which the woman dances cuts 'in front' of the woman sitting at the table). Metzinger represents a subjective effect objectively on the canvas, imitating subjective phenomena (of vision) objectively. Henri Poincaré, in Science and Hypothesis, 1902, discusses 'representative' space (visual, tactile and motor space) versus 'geometrical' space.

Increasing the extra oral dry time increases the likelihood of ankylosis The probability also increases with the severity of intrusion. There is no known treatment to arrest the process. Ankylosis itself is not a reason to remove a permanent tooth, however teeth which must be removed for other reasons are made significantly more difficult to remove if they are ankylosed. Ankylosis in growing patients can result in infra occlusion of teeth, this can lead to an aesthetic and functional deficit.

This allows visibility determination to be performed hierarchically: effectively, if a node in the tree is considered to be invisible, then all of its child nodes are also invisible, and no further processing is necessary (they can all be rejected by the renderer). If a node is considered visible, then each of its children need to be evaluated. This traversal is effectively a tree walk, where invisibility/occlusion or reaching a leaf node determines whether to stop or whether to recurse respectively.

Though the exact pathogenesis of this disorder is unknown, the retinal and brain biopsy findings suggest a small vessel vasculopathy leading to arteriolar occlusion and microinfarction of cerebral, retinal and cochlear tissue. Demyelination is not a typical feature of Susac's syndrome. Muscle biopsies from such patients are usually normal, but some have also shown nonspecific signs of inflammation such as dense hyaline material surrounding endomysial capillaries. This suggests a possible systemic component of this disease, despite the predominance of central nervous system features.

Sensor fusion combines data from several tracking algorithms and can yield better outputs than only one technology. One of the variants of sensor fusion is to merge inertial and optical tracking. While optical tracking would be the main tracking method, but when an occlusion occurs, inertial tracking would estimate the position till the objects would visible to the optical camera again. Inertial tracking could also generate position data in-between optical tracking position data because inertial tracking has higher update rate.

The initial surgery was considered a success and, after a few days, Frei was discharged to continue his recovery at his home. However, Frei began experiencing fever and pain a few days later and was readmitted to the Santa María Clinic on 4 December. After a complete check, he was diagnosed with an intestinal occlusion and a partial necrosis of the small intestine. He underwent a second (corrective) surgery on 6 December, this time performed by Dr. Patricio Silva Garín.

As a consequence, these rigid blood cells are unable to deform as they pass through narrow capillaries, leading to vessel occlusion and ischaemia. The actual anaemia of the illness is caused by haemolysis, the destruction of the red cells, because of their shape. Although the bone marrow attempts to compensate by creating new red cells, it does not match the rate of destruction. Healthy red blood cells typically function for 90–120 days, but sickled cells only last 10–20 days.

In 1941 the college created the first professorship in orthodontics in Europe and appointed Friel to the position. For many years following this he was the only professor of orthodontics in the British Isles. Friel was a pioneer in the use of stainless steel, rather than the previously preferred gold, for the manufacture of orthodontic devices. Other research interests were muscle testing and training, the relation of function to the size and form of jaws, the migration of teeth and occlusion.

The most common symptom of Treacher Collins syndrome is underdevelopment of the lower jaw and underdevelopment of the zygomatic bone. This can be accompanied by the tongue being retracted. The small mandible can result in a poor occlusion of the teeth or in more severe cases, trouble breathing or swallowing. The respiratory system of a child with Treacher Collins syndrome is the primary concern when the child is born and other concerns are addressed after respiratory issues have been addressed.

Use of depth weighting during production of rotating cines of MIP images can avoid the problem of difficulty of distinguishing right from left, and clockwise vs anti-clockwise rotation. An easy improvement to MIP is Local maximum intensity projection. In this technique we don't take the global maximum value, but the first maximum value that is above a certain threshold. Because - in general - we can terminate the ray earlier this technique is faster and also gives somehow better results as it approximates occlusion.

Take care to ensure that all the fingers/toes are enclosed within the device. ## The handles of the tourniquet should be positioned medial-lateral on the upper extremity or posterior-anterior on the lower extremity. ## The person applying the device should start rolling the device while the individual responsible for the limb should hold the limb straight and maintain axial traction. ## Once the desired occlusion location is reached, the straps can be cut off or tied just below the ring.

Depending upon the area and severity of the occlusion, signs and symptoms may vary within the population affected with ACA syndrome. Blockages to the proximal (A1) segment of the vessel produce only minor deficits due to the collateral blood flow from the opposite hemisphere via the anterior communicating artery. Occlusions distal to this segment will result in more severe presentation of ACA syndrome. Contralateral hemiparesis and hemisensory loss of the lower extremity is the most common symptom associated with ACA syndrome.

Optical flow (OF) helps in determining the relative pixel velocity of points within an image sequence. Like image difference, it is also an old concept used for segmentation. Initially the main drawback of OF was the lack of robustness to noise and high computational costs but due to recent key-point matching techniques and hardware implementations, these limitations have diminished. To increase its robustness to occlusion and temporal stopping, OF is generally used with other statistical or image difference techniques.

Non-proliferative retinopathy is often caused by direct damage or remodeling of the small blood vessels supplying the retina. Many common causes of non-proliferative damage include hypertensive retinopathy, retinopathy of prematurity, radiation retinopathy, solar retinopathy, and sickle cell retinopathy. There are three main mechanisms of damage in non-proliferative retinopathy: blood vessel damage or remodeling, direct retinal damage, or occlusion of the blood vessels. The first mechanism is indirect damage by altering the blood vessels that supply the retina.

Fetoscopy is an endoscopic procedure during pregnancy to allow surgical access to the fetus, the amniotic cavity, the umbilical cord, and the fetal side of the placenta. A small (3–4 mm) incision is made in the abdomen, and an endoscope is inserted through the abdominal wall and uterus into the amniotic cavity. Fetoscopy allows for medical interventions such as a biopsy (tissue sample) or a laser occlusion of abnormal blood vessels (such as chorioangioma) or the treatment of spina bifida.Kohl, Thomas.

(Cobas b 221 - Roche Diagnostics). Arterial blood for blood-gas analysis is usually drawn by a respiratory therapist and sometimes a phlebotomist, a nurse, a paramedic or a doctor. Blood is most commonly drawn from the radial artery because it is easily accessible, can be compressed to control bleeding, and has less risk for vascular occlusion.

The reason for this lies in the mechanism of filtration of BUN and creatinine. Renal Plasma Flow (RPF) is decreased due to hypoperfusion which results in a proportional decrease in GFR. In turn, the decreased flow and pressure to the kidney will be sensed by baroreceptors in the Juxtaglomerular (JG) Cells of the afferent arteriole. If the decrease in blood pressure is systemic (rather than occlusion of the renal artery) baroreceptors in the carotid sinus and aortic arch will be stimulated.

Heat and moisture exchanger (HME) Heat and Moisture Exchangers (HME) are devices used in mechanically ventilated patients intended to help prevent complications due to "drying of the respiratory mucosa, such as mucus plugging and endotracheal tube (ETT) occlusion." HMEs are one type of commercial humidification system, which also include non-heated-wire humidifiers and heated-wire humidifiers. HMEs have been in clinical use for over 30 years. An HME cassette plays a central part of lung rehabilitation after a total laryngectomy.

UAE also appears to require more repeat procedures than if surgery was done initially. A person will usually recover from the procedure within a few days. Uterine artery ligation, sometimes also laparoscopic occlusion of uterine arteries are minimally invasive methods to limit blood supply of the uterus by a small surgery that can be performed transvaginally or laparoscopically. The principal mechanism of action may be similar like in UAE but is easier to perform and fewer side effects are expected.

Prior to designing partial dentures a complete examination is undertaken to assess the condition of remaining teeth. This may involve radiographs, sensibility testing or other assessments. From this examination and assessment of occlusion (occlusal plane, drifting, tilting of teeth and surveyed articulated casts) the designing of partial dentures can begin. Information from previous dentures can be very useful in deciding which features to keep the same and which features of the design to change – in the hope of making an improvement.

The incidence of dens evaginatus has been reported to affect up to 6% of the population, with greater incidence in certain ethnic groups. Dens invaginatus is a rare dental anomaly where there is an infolding of enamel into the dentine. The presence of dens evaginatus can lead to rapid pulpal necrosis when there is continuous trauma from occlusion. In both dens evaginatus and dens invaginatus, direct exposure of pulp to the oral environment will eventually lead to inflammation and infection of the pulp.

Photothrombotic models of ischemic stroke use local intravascular photocoagulation of circumscribed cortical areas. After intravenous injection of photosensitive dyes like rose-bengal, the brain is irradiated through the skull via a small hole or a thinned cranial window, leading to photochemical occlusion of the irradiated vessels with secondary tissue ischemia . This approach was initially proposed by Rosenblum and El- Sabban in 1977, and improved by Watson in 1985 in the rat brain. This method has also been adapted for use in mice.

The vasoconstrictive occlusion appears to be mainly mediated by serotonin and thromboxane A2. The artery in cords of preterm infants contracts more to angiotensin II and arachidonic acid and is more sensitive to oxytocin than in term ones. In contrast to the contribution of Wharton's jelly, cooling causes only temporary vasoconstriction. Within the child, the umbilical vein and ductus venosus close up, and degenerate into fibrous remnants known as the round ligament of the liver and the ligamentum venosum respectively.

Angiography (left) and CT (middle and right) of chronic total occlusion lesions at the left anterior descending coronary artery (LAD) and right coronary artery (RCA). CT angiography can act as a less invasive alternative to Catheter angiography. Instead of a catheter being inserted into a vein or artery, CT angiography involves only the injection of a CT-visible dye into the arm or hand via an IV line. CT angiography lowers the risk of arterial perforation and catheter site infection.

He fined Christopher Burke 5 shillings, though Michael Burke's lawyer, Mr. Tallan said he was more concerned with Christopher and Joseph Burke getting a dwelling somewhere else. After this, Christopher Burke went into the dairy business with his brother, Joseph Burke, and built a house on the family farm in Bryanstown, County Meath. He died from coronary occlusion at the age of 65 in his home on 23 June 1964. His sister, Christina Mary "Tena" Burke was present at his death.

This included reduction of the buccal cusp in the upper teeth and the lingual cusp of lower teeth in the frontal plane. Additionally, on the sagittal plane reductions are made on the mesial cusp for upper teeth and distal cusp of the lower teeth. Schuler developed this rule on an articulator whose movement is converse to the natural mandibular movement. One of the key factors in establishing the balanced occlusion is the assumption that condylar guidance of the patient is constant or fixed.

Restenosis was reduced because the stent acted as a scaffold to hold open the dilated segment of artery; acute closure of the coronary artery (and the requirement for emergency CABG) was reduced, because the stent repaired dissections of the arterial wall. By 1999, stents were used in 84% of percutaneous coronary interventions (i.e., those done via a catheter, and not by open-chest surgery). Early difficulties with coronary stents included a risk of early thrombosis (clotting) resulting in occlusion of the stent.

The first treatment was performed in 1970 in Moscow, with the occlusion of an internal carotid to treat a carotid-cavernous fistula. He can be considered, therefore, the first interventional neuroradiologist. This technique was subsequently refined by neuroradiologists all over the world and mainly in France, where interventional neuroradiology developed and flourished. Parallel to the development of catheters, in the radiology and neuroradiology units, image technology dramatically improved: Charles Mistretta in 1979 invented digital subtraction angiography (DSA), the technique currently in use.

Occlusal factors as an etiologic factor in TMD is a controversial topic. Abnormalities of occlusion (problems with the bite) are often blamed for TMD but there is no evidence that these factors are involved. Occlusal abnormalities are incredibly common, and most people with occlusal abnormalities do not have TMD. Although occlusal features may affect observed electrical activity in masticatory muscles, there are no statistically significant differences in the number of occlusal abnormalities in people with TMD and in people without TMD.

Further, using fluoroscopy or hysteroscopy proximal tubal occlusion can be overcome by unilateral or bilateral selective tubal cannulation, a procedure where a thin catheter is advanced through the proximal portion of the fallopian tube os to examine and possibly restore tubal patency salpinostomy (creating an opening for the tube) or falloposcopy. Results of tubal surgery are inversely related to damage that exists prior to surgery. Development of adhesions remains a problem. Patients with operated tubes are at increased risk for ectopic pregnancy.

An embolism is the lodging of an embolus, a blockage-causing piece of material, inside a blood vessel. The embolus may be a blood clot (thrombus), a fat globule (fat embolism), a bubble of air or other gas (gas embolism), or foreign material. An embolism can cause partial or total blockage of blood flow in the affected vessel.Britannica Concise Encyclopedia 2007 Such a blockage (a vascular occlusion) may affect a part of the body distant from the origin of the embolus.

Pain control can be difficult to achieve at times because of anesthetic inactivation by the acidity of the abscess around the tooth apex. Sometimes the abscess can be drained, antibiotics prescribed, and the procedure reattempted when inflammation has been mitigated. The tooth can also be unroofed to allow drainage and help relieve pressure. A root treated tooth may be eased from the occlusion as a measure to prevent tooth fracture prior to the cementation of a crown or similar restoration.

Vilevolodon is an extinct, monotypic genus of volant, arboreal euharamiyids from the Oxfordian age of the Late Jurassic of China. The type species is Vilevolodon diplomylos. The genus name Vilevolodon references its gliding capabilities, Vilevol (Latin for “glider”), while don (Greek for “tooth”) is a common suffix for mammalian taxon titles. The species name diplomylos refers to the dual mortar-and-pestle occlusion of upper and lower molars observed in the holotype; diplo (Greek for “double”), mylos (Greek for “grinding”).

The hypocone is found on the distal lingual side of the tooth. It fits into the grooves of the lower dentition and is an adaptation for the overall grinding and tearing of foods using the occlusal (chewing side) of the tooth surface during occlusion or mastication (chewing). Its strength is due to the thickness of the enamel which differs among species of hominids. The hypocone appears to have evolved independently more than twenty times in different mammal groups during the Cenozoic period.

In test with rabbits, significant improvement in protection against arrhythmic effects and infarct size reduction was observed after administrating exogenously SRTX-c (in dosage of 0.24 nmol/kg, i.v.) prior the coronary occlusion accident. That was achieved thanks to ability of SRTX-c to activate selected ETB receptors. In rat thoracic aorta, the contractile activity is grouped as follows: ET-1 > SRTX-b > SRTX-a > SRTX-c at lower concentrations, but SRTX-b > ET-1 > SRTX-a > SRTX-c at higher concentrations.

In order to fully understand the development of occlusion and malocclusion, it is important to understand the premolar dynamics in the mixed dentition stage. The mixed dentition stage is when both primary and permanent teeth are present. The permanent premolars erupt ~9–12 years of age, replacing the primary molars. The erupting premolars are smaller than the teeth they are replacing and this difference in space between the primary molars and their successors (1.5mm for maxillary, 2.5mm for mandibular), termed Leeway Space.

These vascular stents, implanted in peripheral and coronary circulation, were multi-filament self-expanding, spring-like devices made of surgical steel. Sigwart's work made angioplasty predictable which significantly improved the outcome and offered a chance to overcome the problem of abrupt closure and recurrence. Sigwart's early stenting work received great interest and many travelled to Lausanne to observe the technique in practice. In a 1987 paper entitled ‘Intravascular stents to prevent occlusion and restenosis after transluminal angioplasty’, Sigwart et al.

But bronchial circulation supplies fully oxygenated arterial blood to the lung tissues themselves. This blood supplies the bronchi and the pleura to meet their nutritional requirements. Because of the dual blood supply to the lungs from both the bronchial and the pulmonary circulation, this tissue is more resistant to infarction. An occlusion of the bronchial circulation does not cause infarction, but it can still occur in pulmonary embolism when the pulmonary circulation is blocked and the bronchial circulation cannot fully compensate for it.

The disease moyamoya, which is a Japanese mimetic word, gets its characteristic name due to the appearance of smoke on relevant angiographs resultant from the tangle of tiny vessels in response to stenosis. This makes the blood leak out of the arteries, causing pressure to the brain and subsequent headaches. The pathogenesis of moyamoya disease is unknown, although the gene ring finger protein 213 (RNF213) has been implicated. Once it begins, the vascular occlusion tends to continue despite any known medical management.

A fully-adjustable articulator reproduces the movement of the temporomandibular joints in all possible dimensions and functional movements. They are necessary for large or complex restorative cases where a correct occlusion is being substantively restored. The relationship between the temporomandibular joints and the maxilla and the functional relationship of the jaws are transferred to the articulator by means of a separate facebow. Individual patient's casts may be mounted and dismounted from a single articulator using a variety of disposable baseplates, either mechanical or magnetic.

Commonly, 3D geometry with transparency is rendered by blending (using alpha compositing) all surfaces into a single buffer (think of this as a canvas). Each surface occludes existing color and adds some of its own color depending on its alpha value, a ratio of light transmittance. The order in which surfaces are blended affects the total occlusion or visibility of each surface. For a correct result, surfaces must be blended from farthest to nearest or nearest to farthest, depending on the alpha compositing operation, over or under.

Quick determination of the cause may lead to urgent measures to save the eye and life of the patient. High clinical suspicion should be kept for painless vision loss in patients with atherosclerosis, deep venous thrombosis, atrial fibrillation, pulmonary thromboembolism or other previous embolic episodes. Those caused by a carotid artery embolism or occlusion have the potential for further stroke by detachment of embolus and migration to an end-artery of the brain. Hence, proper steps to prevent such an eventuality need to be taken.

The current selection of dentifrice should also be critically analysed and changed to include a less abrasive and gentler paste such as sensitive toothpaste as evidence suggests that a very abrasive toothpaste would lead to loss of tooth structure. A toothpaste containing increased fluoride will also help combat the increased sensitivity and risk to dental decay.Seong J, Parkinson CP, Davies M, Claydon NC, West NX. Randomised clinical trial to evaluate changes in dentine tubule occlusion following 4 weeks use of an occluding toothpaste. Clinical Oral Investigations.

The treatment of horizontally root-fractured teeth involves re-positioning, stabilisation and occlusion adjustment, with a good chance of survival. The exception to this is when the horizontal fracture affects the coronal third of the root, in which case extraction is necessary in 80% of cases. In this case of pulpal necrosis, which occurs in 20-44% of root fracture cases, this can be treated through root canal treatment or endodontic surgery. When the coronal fragment of the tooth is stable, then splinting is unnecessary.
|
|
Splinting should only be done when other aetiologies are addressed, such as periodontal disease or traumatic occlusion, or when treatments are difficult due to the lack of tooth stabilization. splinting allows healing and functions during tissue healing. Main disadvantage of splinting is it makes removal of plaque more difficult, as there will be increased plaque retention at the margins of the splint, which can cause periodontal disease and further loss of periodontal support. A dental splint works by evening out pressure across a patients jaw.

A test called the Bielschowsky Darkening Wedge Test can be used to reveal and diagnose the presence of dissociated vertical deviation, although any (or no) amount of dissociative occlusion may also prompt it to occur. The patient is asked to look at a light. One eye is covered and a filter is placed in front of the other eye. The density or opacity of this filter is gradually increased, and the behaviour of the eye under the cover (not of the eye beneath the filter) is observed.

A wallet constructed mainly from duct tape Duct tape's widespread popularity and multitude of uses has earned it a strong place in popular culture, and has inspired a vast number of creative and imaginative applications. Duct tape occlusion therapy (DTOT) is a method intended to treat warts by covering them with duct tape for an extended period. The evidence for its effectiveness is poor; thus it is not recommended as routine treatment. However, other studies suggest the duct tape treatment is more effective than existing medical options.

People with coronary artery disease might have just one or two plaques, or might have dozens distributed throughout their coronary arteries. A more severe form is chronic total occlusion (CTO) when a coronary artery is completely obstructed for more than 3 months. Cardiac syndrome X is chest pain (angina pectoris) and chest discomfort in people who do not show signs of blockages in the larger coronary arteries of their hearts when an angiogram (coronary angiogram) is being performed. The exact cause of cardiac syndrome X is unknown.

Contrary to many previously published accounts, T. P. Lee had no sons. At age sixty-seven, Thomas Peter Lee died of a coronary occlusion on February 4, 1939, and he was buried at Glenwood Cemetery in Houston, two days later. Lee's former home, now referred to as the Link–Lee House, and its surrounding area, became the basis of the founding of the University of St. Thomas (Houston) which still occupies the site today. In particular, the house serves as the university's administration building.

They are relatively easy to match against a (large) database of local features but, however, the high dimensionality can be an issue, and generally probabilistic algorithms such as k-d trees with best bin first search are used. Object description by set of SIFT features is also robust to partial occlusion; as few as 3 SIFT features from an object are enough to compute its location and pose. Recognition can be performed in close-to-real time, at least for small databases and on modern computer hardware.

It is common for an individual with a fistula to compensate for a loss of pressure during speech sound production by attempting to regulate intraoral air pressure with increasing respiration effort and using compensatory articulation. Middorsum palatal stops (atypical place of articulation) often results from palatal fistulae causing sound distortions during speech. Occlusion for the fistula is attempted by speakers with deviant tongue placements during these palatal stops. The palatal obturation may be managed temporarily or may be sustained for longer periods of time.

The preceding volumetric systems were projecting the images in a diffuse plane of rotation, thus, the light was remaining dispersed in all directions. Unfortunately, these displays could not recreate dependent effects as for example the occlusion. There was created, therefore, the need to create a system that was capable of settling misadventures as this one, but in turn it had an easy implementation and was doing that his installation on systems was simple. Thus, create a System of gyratory mirrors covered by a holographic diffuser anisotropic.

Furthermore, any active disease including caries or periodontal disease should be treated and followed by a period of maintenance to ensure patient compliance in maintaining appropriate oral hygiene. Study models mounted on a semi-adjustable articulator using a facebow record are a useful aid to study occlusion prior to provision of a fixed prosthesis. They may also be used to practice planned tooth preparation. Subsequently a diagnostic wax up can be provided to help the patient visualise the final prosthesis and to construct a silicone index.
|
|
The wax up can also be used to construct a putty matrix which can be used subsequently to make a temporary restoration. #Restoration replacement: Restorations in abutment teeth with questionable prognosis or old composite resin restorations for adhesive bridgework should be replaced. #Tooth preparation: This should be completed with reference to radiographs and study casts obtained during treatment planning. For conventional bridges, tooth preparation should aim to conserve tooth tissue, ensure a parallel path of insertion, achieve clearance in the occlusion and ensure well defined preparation margins.

Bleeding complication, pseudoaneurysm, hematoma formation are less than 2% with transradial catheterization. Possibility of blood transfusion requirement is extremely rare after transradial catheterization. The other reason for the increased use of radial access is the technological advances in the sheath and catheter design, and improved physician experience with this approach. With improvement in the physician's experience, radial artery access is now being used with equal efficacy to treat almost every complex coronary artery disease, including acute myocardial infarction, chronic total occlusion, bifurcation coronary artery disease and rotablation.

The location of the wheeze can also be an important clue to the diagnosis. Diffuse processes that affect most parts of the lungs are more likely to produce wheezing that may be heard throughout the chest via a stethoscope. Localized processes, such as the occlusion of a portion of the respiratory tree, are more likely to produce wheezing at that location, hence the sound will be loudest and radiate outwardly. The pitch of a wheeze does not reliably predict the degree of narrowing in the affected airway.

Photoplethysmography of the thumb by holographic laser Doppler imaging. pulsatile waves on the back of a frog measured by holographic photoplethysmography Remote photoplethysmography can also be performed by digital holography, which is sensitive to the phase of light waves, and hence can reveal sub-micron out-of-plane motion. In particular, wide-field imaging of pulsatile motion induced by blood flow can be measured on the thumb by digital holography. The results are comparable to blood pulse monitored by plethysmoraphy during an occlusion-reperfusion experiment .

On 11 December 2011, the Met Office had noted a complex weather system over the central Atlantic, associated with several warm and cold fronts. An amplified jet stream—a strong and fast-moving airstream aloft—advanced eastward, sparking rapid cyclogenesis along the fronts. By the following day, a low-pressure centre had developed along an occlusion between two of the fronts. The low rapidly deepened as it approached the British Isles, with a developing occluded rainband producing sustained winds of up to 60 mph (95 km/h).

As rodents, mice must gnaw to keep their incisors from growing too long. Overgrown teeth can cause occlusion (blockage) of the mouth, which in extreme cases can lead to starvation. Hard foodstuffs, small pieces of wood or specially prepared blocks can suit this purpose, although some mice can grind their teeth together ("bruxing") to keep them short. In rare cases, a mouse may not be able to gnaw effectively, either from malformed incisors or jaws, and so its teeth must be trimmed by a veterinarian.

Coronary collateralization exists latently in the normal heart. Microscopic collateral vessels of the heart undergo a process called transformation that widens the vessel lumen at the expense of its cell wall in response to myocardial stresses—specifically, myocardial spasm and hypoxia secondary to myocardial infarction or acutely stressful exercise. The status of the coronary collaterals has also been shown to be influenced by the presence of diabetes mellitus.Kilian JG, Keech A, Adams MR, Celermajer DS. Coronary collateralization: determinants of adequate distal vessel filling after arterial occlusion.

Rentrop KP, et al., "Changes in collateral filling immediately after controlled coronary artery occlusion by an angioplasty balloon in human subjects," Journal of the American College of Cardiology 1985; 5: 587-92. Filling improved in 15 of 16 patients; neither chest pain nor pre-inflation angina correlated with the extent of collateral filling, and coronary spasm did not occur. Rentrop did not generalize about the functional significance of these collaterals, which he said was "unknown," but their existence suggests that they may exert a preemptive, protective effect.

Next, the damaged segments of the trachea and the artery should be excised followed by reconstruction with a primary end to end anastomosis of the trachea. Innominate artery ligation leaves the carotid and subclavian circulations intact. Pulsatile back-bleeding from distal innominate artery stump should be checked to insure collateral circulation. In patients with poor pulsatile back-bleeding, an aorta-axillary artery bypass graft can be considered in patients with severe occlusion of the left common carotid artery, severe atherosclerosis, and brain ischemic or hemorrhagic insults.

Diagram of a cyclone in the early stages of occlusion in the Northern Hemisphere In meteorology, an occluded front is a weather front formed during the process of cyclogenesis, when a cold front overtakes a warm front. When this occurs, the warm air is separated (occluded) from the cyclone center at the Earth's surface. The point where the warm front and the occluded front meet (and consequently the nearest location of warm air to the center of the cyclone) is called the triple point.Djurić, D: "Weather Analysis".

In an associated / premultiplied alpha image, the RGB represents the emission amount, while the alpha is occlusion. Premultiplied alpha has some practical advantages over normal alpha blending because interpolation and filtering give correct results. Ordinary interpolation without premultiplied alpha leads to RGB information leaking out of fully transparent (A=0) regions, even though this RGB information is ideally invisible. When interpolating or filtering images with abrupt borders between transparent and opaque regions, this can result in borders of colors that were not visible in the original image.

Closure of the umbilical artery by vasoconstriction consists of multiple constrictions which increase in number and degree with time. There are segments of dilatations with trapped uncoagulated blood between the constrictions before complete occlusion. Both the partial constrictions and the ultimate closure are mainly produced by muscle cells of the outer circular layer. In contrast, the inner layer seems to serve mainly as a plastic tissue which can easily be shifted in an axial direction and then folded into the narrowing lumen to complete the closure.

Mary Sherwood was born on March 31, 1856, in Ballston Spa, New York, and was one of three children to Thomas Burr Sherwood, a lawyer and farmer, and Mary Frances (Beattie) Sherwood. Her sister, Margaret Pollock Sherwood became an English professor at Wellesley College and her brother, Sidney Sherwood, became a professor at Johns Hopkins University. She never married or had children, but formed close bonds with her long time friend, Lilian Welsh. She later died at 79 years of age of a coronary occlusion.

The initial movement inside this envelope is directed by the shape of the teeth in contact and the Glenoid Fossa/ Condyle shape. The outer extremities of this envelope are limited by muscles, ligaments and the acticular disc of the TMJ. Without the guidance of anterior incisors and canines, this envelope of function can be destructive to the remaining teeth resulting in periodontal trauma from occlusion seen as wear, fracture or tooth loosening and loss. The premolars and molars are at the back of the mouth.

This period may extend to a couple of minutes if complications, such as arterial occlusion, occur. However, the animal's inverted position allows blood to flow more precipitously and thus makes an animal regaining consciousness before it is fully exsanguinated highly unlikely. In any case, animal welfare advisory councils clearly emphasize that the time from incapacitation to start of exsanguination should be prompt; recommending a time under 15 seconds. Beyond the initial cost of purchasing a captive bolt, continued usage of the method is very inexpensive.

Strabismus can be manifest (-tropia) or latent (-phoria). A manifest deviation, or heterotropia (which may be eso-, exo-, hyper-, hypo-, cyclotropia or a combination of these), is present while the person views a target binocularly, with no occlusion of either eye. The person is unable to align the gaze of each eye to achieve fusion. A latent deviation, or heterophoria (eso-, exo-, hyper-, hypo-, cyclophoria or a combination of these), is only present after binocular vision has been interrupted, typically by covering one eye.

The rate of pregnancy depends on such factors as the method used for the vasectomy and the length of time that has passed since the vasectomy was performed. The reversal procedures are frequently impermanent, with occlusion of the vas recurring two or more years after the operation. The presence of sperm granulomas improves the likelihood of restoring sperm to the semen with a vasovasotomy. A local urologist can easily determine whether you have 0, 1, or 2 sperm granuloma by a painless examination of each vasectomy site.

Among patients with ocular Behçet's disease funduscopic findings of optic atrophy, and optic disc paleness have been identified with a frequency of 17.9 percent and 7.4 percent, respectively. Other fundoscopic findings include vascular sheathing (23.7%), retinal hemorrhage (9%), macular edema (11.3%), branch retinal vein occlusion (5.8%), and retinal edema (6.6%). However, optic atrophy was the most significant cause of visual impairment identified in 54 percent of patients with ocular Behçet's disease and permanent visual impairment. The prevalence of this disease increases from North to South.

Gysi's geometric theories of non-functional movement formed the basis of modern concepts of balanced occlusion. The studies illustrate the geometric variety of rotation centre about its asymmetrical location. To achieve this result, he relays a symmetrical fixed rotation on the articulator assuming that this can be used and ideal for complex anatomical situations. Using this concept, the patient can be trained to open their mandible without movement in the condylar path, demonstrated by McCollum and this movement point located in the condyle, called hinge axis.

Overall between 1966 and 2007, most of the research published was focused on occlusal adjustments and oral splints. Behavioral approaches in research declined from over 60% of publications in the period 1966–86 to about 10% in the period 1997–2007. In the 1960s, a periodontist named Sigurd Peder Ramfjord championed the theory that occlusal factors were responsible for bruxism. Generations of dentists were educated by this ideology in the prominent textbook on occlusion of the time, however therapy centered around removal of occlusal interference remained unsatisfactory.

Dexamethasone intravitreal steroid implants have been approved by the FDA to treat ocular conditions such as diabetic macular edema, central retinal vein occlusion, and uveitis. Dexamethasone has also been used with antibiotics to treat acute endophthalmitis. Dexamethasone is used in transvenous screw-in cardiac pacing leads to minimize the inflammatory response of the myocardium. The steroid is released into the myocardium as soon as the screw is extended and can play a significant role in minimizing the acute pacing threshold due to the reduction of inflammatory response.

The closest examples in English are consonant clusters such as the [nd] in candy, but many languages have prenasalized stops that function phonologically as single consonants. Swahili is well known for having words beginning with prenasalized stops, as in ndege 'bird', and in many languages of the South Pacific, such as Fijian, these are even spelled with single letters: b [mb], d [nd]. A postnasalized plosive begins with a raised velum that lowers during the occlusion. This causes an audible nasal release, as in English sudden.

However, in patients with large deviations, the thickness of the prism required may reduce vision so much that binocularity is not achievable. In such cases it may be more appropriate simply to occlude one eye temporarily. Occlusion would never be used in infants though both because of the risk of inducing stimulus deprivation amblyopia and because they do not experience diplopia. Other management options at this initial stage include the use of botulinum toxin, which is injected into the ipsilateral medial rectus (botulinum toxin therapy of strabismus).

Hydrosalpinx may be diagnosed using ultrasonography as the fluid filled elongated and distended tubes display their typical echolucent pattern. However, a small hydrosalpinx may be missed by sonography. During an infertility work-up a hysterosalpingogram (HSG), an X-ray procedure that uses a contrast agent to image the fallopian tubes, shows the retort-like shape of the distended tubes and the absence of spillage of the dye into the peritoneum. If, however, there is a tubal occlusion at the utero-tubal junction, a hydrosalpinx may go undetected.

Further additions include smooth changes between EAX environment presets and audio occlusion effects (simulating a wall between player and sound source). EAX was used in many popular titles of the time, including Doom 3, F.E.A.R., Counter-Strike, and Prey. These games support EAX 4.0 if audio hardware with an OpenAL-supporting driver is present. Because hardware acceleration for DirectSound and DirectSound3D was dropped in Windows Vista,, Creative Labs OpenAL will likely become more important for game developers who wish to use EAX in their games.

Structurally, hytrosaviruses are similar to members of other arthropod-infecting virus families such as Baculoviridae, Nudiviridae and Nimaviridae. Hytrosaviruses share 12 of the 38 core genes that have been described in baculoviruses, nudiviruses, nimaviruses and some bracoviruses. Some of the structural and genomic features shared between hytrosaviruses and other large, dsDNA viruses include the possession of enveloped, rod-shaped virions, circular dsDNA genomes and replication in the nucleus of infected cells. However, hytrosaviruses differ functionally with baculoviruses by the lack of occlusion bodies and lower lethality.

Hytrosaviruses encode homologs to the core and highly conserved oral infectivity factor (PIF) genes found in other dsDNA viruses (PIFs o/P74, 1,2 and 3), and occlusion-derived virus (ODV) envelop of epidopteran baculoviruses (OVD-E66). Also found in hytrosaviruses are homologs to some of the subunits of the DNA-dependent RNA polymerase (DdRp) comlex found in baculoviruses and nudivuses. The DdRp complex components present in the hytrosaviruses include the late expression factors 4, 5, 8 and 9 (LEF-4, LEF-5, LEF-8 and LEF-9).

Tooth contact involved in guidance is particularly important as these occlude a vast number of times per day and so need to be able to resist both heavy and non-axial occlusal loads. When restoring the anterior guidance system should be compatible with the posterior guidance system. This means that excessive strain should not be applied on the posterior guidance system which is limited by the ligametous structures. Upon restoration of the occlusal surfaces of teeth, it is likely to change the occlusion and therefore guidance systems.

There are numerous NPVs, many of which were isolated from the cabbage looper or the alfalfa looper. NPVs vary in infectivity and virulence. For example, the AcMNPV isolates are more infectious than the TnSNPV isolates in the first instar, while the TnSNPV isolates produced more occlusion bodies, protein structures that protect the virus and increase long term infectivity. TnSNPVs are their most lethal during the third and fourth instars; they have detrimental effects such as delayed development, reduced egg production, and fewer hatched eggs.

The A domain serves as a built-in protein phosphatase that functions to dephosphorylate the phosphorylated P domain. The A domain is the smallest of the three cytoplasmic domains. It consists of a distorted jellyroll structure and two short helices. It is the actuator domain modulating the occlusion of the transported ligand(s) in the transmembrane binding sites, and it is pivot in transposing the energy from the hydrolysis of ATP in the cytoplasmic domains to the vectorial transport of cations in the transmembrane domain.

In severe cases, after enough rest the patient may require physical therapy to regain strength and movement back to the leg. A SCFE is an orthopaedic emergency, as further slippage may result in occlusion of the blood supply and avascular necrosis (risk of 25 percent). Almost all cases require surgery, which usually involves the placement of one or two pins into the femoral head to prevent further slippage. The recommended screw placement is in the center of the epiphysis and perpendicular to the physis.

Left sided cerebellar stroke due to occlusion of a vertebral artery Cerebellar stroke syndrome is a condition in which the circulation to the cerebellum is impaired due to a lesion of the superior cerebellar artery, anterior inferior cerebellar artery or the posterior inferior cerebellar artery. Cardinal signs include vertigo, headache, vomiting, and ataxia. Cerebellar strokes account for only 2-3% of the 600,000 strokes that occur each year in the United States. They are far less common than strokes which occur in the cerebral hemispheres.

As teeth flex under pressure, the arrangement of teeth touching each other, known as occlusion, causes tension on one side of the tooth and compression on the other side of the tooth. This is believed to cause V-shaped depressions on the side under tension and C-shaped depressions on the side under compression. When tooth destruction occurs at the roots of teeth, the process is referred to as internal resorption, when caused by cells within the pulp, or external resorption, when caused by cells in the periodontal ligament.

The RFD initiates the tornado, occludes around the mesocyclone, and when it wraps completely around, cuts off the inflow causing death of the low- level mesocyclone (or "tornado cyclone") and tornadolysis. Therefore, in most cases, the RFD is responsible for both the birth and the death of a tornado. Usually, but not always, the dry slot occlusion is visible (assuming one's line of sight is not blocked by precipitation) throughout the tornado life cycle. The wall cloud withers and will often be gone by the time the tornado dissipates.

This theory is not widely accepted among the professional community as it suggests that the only factor is occlusion. Many researchers argue that this is inaccurate as they contend that the abfraction lesion is a multifactorial (has many causative factors) lesion with other factors such as abrasion or erosion. This controversy around the causative factors, along with the recency of the lesion classification, are some of the reasons why many dental clinicians are looking at the lesion with some scepticism. More research is needed to fully clear up the controversy surrounding the abfraction lesion.

In May 2006, it was detected on De Camps an intestinal occlusion attributed to a diverticulitis, reason by which he required an urgent surgery in the Columbia Presbyterian Medical Center of New York. The following month, De Camps revealed that it was excised a cancerous tumor in his colon. In late 2015 his state of health worsened and De Camps presented a scrawny look. On 25 May 2016, after the general elections, trascended the rumour that De Camps had died, version that was debunked; De Camps was in his residence ailed by a flu.

Bergeron was one of the principal scientists in the Bergen School of Meteorology, which transformed this science by introducing a new conceptual foundation for understanding and predicting weather. While developing innovative methods of forecasting, the Bergen scientists established the notion of weather fronts and elaborated a new model of extratropical cyclones that accounted for their birth, growth, and decay. Bergeron is credited with discovering the occlusion process, which marks the final stage in the life cycle of an extratropical cyclone. In 1949 he was awarded the Symons Gold Medal of the Royal Meteorological Society.

Systematic reviews show evidence to support the use of systemic retinoids alone and in combination with photochemotherapy to improve symptoms of chronic palmoplantar pustulosis, with a combination more effective than one alone. There is also evidence to support topical steroids under hydrocolloid occlusion dressings, low dose ciclosporin, tetracyclines, and Grenz-Ray Therapy. There is no evidence to support the use of hydroxyurea in chronic palmoplantar pustulosis. Treatment with guselkumab, an anti–interleukin 23 monoclonal antibody has shown a decrease in the size of the area affected and severity.

Neurological imaging has shown that TMoA is typically caused by an infarct of the anterior superior frontal lobe in the perisylvian area of the left, or language-dominant, hemisphere. The anterior superior frontal lobe is known as the prefrontal cortex which is responsible for the initiation and ideation of verbal speech. The damage leaves the major language networks, Broca's and Wernicke’s areas and the arcuate fasiculus, unaffected. Brain injury can result from a stroke caused by left anterior cerebral artery (ACA) occlusion, brain tumors, traumatic brain injury (TBI), or progressive neurological disorders.

A stop with no audible release, also known as an unreleased stop or an applosive, is a stop consonant with no release burst: no audible indication of the end of its occlusion (hold). In the International Phonetic Alphabet, lack of an audible release is denoted with an upper-right corner diacritic () after the consonant letter: , , .The diacritic may not display properly with some fonts, appearing above the consonant rather than after it; in such cases, , , may be used instead. Audibly released stops, on the other hand, are not normally indicated.

The princess was admitted to Siriraj Hospital in June 2007, suffering from abdominal pains. The doctors found she had cancer, and she remained in the hospital for treatment. In October 2007, doctors reported the princess had suffered an infarction on the left side of her brain as a result of occlusion of a cerebral artery. At the same time in October, her brother, King Bhumibol Adulyadej was treated at Siriraj after he experienced weakness on his right side; doctors later found out through scans that he had a blood shortage to his brain.

The full extent of the damage caused by occlusion of the anterior choroidal artery is not known. However, studies show that the interruption of blood flow from this vessel can result in hemiplegia on the contralateral (opposite) side of the body, contralateral hemi-hypoesthesia, and homonymous hemianopsia. These symptoms are thought to arise from ischemic damage to the posterior limb of the internal capsule, thalamus, and optic chiasm/optic tract. However, the posterior limb of the internal capsule also receives lenticulostriate arteries from the middle cerebral artery, thus creating partially redundant supply.

Rap1 contains a Sir3-binding domain that recruits SIR3 to the silencers. Once at the silencers, Sir3 recruits Sir4-Sir2 dimers to the chromatin nucleation site. Sir2 then deacetylates histone H3 and H4 tails, and free Sir3 binds the now-deacetylated lysine residues H4K16,79, and recruits additional Sir4-Sir2 dimers to promote the further spreading of the heterochromatin domain. Once it has spread to cover a genomic locus, the SIR2,3,4 effectively prevents transcription from the region it occupies, in a process that is thought to depend on the physical occlusion of DNA by SIR proteins.

One form of thrombosis is the formation of a fibrin sheath around the catheter, and is one of the most common causes of catheter obstruction. It is indirectly seen in these images before and after radiocontrast infusion, as the radiocontrast collects around the catheter. Venous catheters may occasionally become occluded by kinks in the catheter, backwash of blood into the catheter leading to thrombosis, or infusion of insoluble materials that form precipitates. However, thrombosis is the most common cause of central line occlusion, occurring in up to 25% of catheters .

Third, hyperglycemia causes an increase in diacylglycerol, which is also an activator of the Protein Kinase C (PKC) signaling pathway. Induction of PKC causes multiple deleterious effects, including but not limited to blood flow abnormalities, capillary occlusion and pro-inflammatory gene expression. Finally, glucose, as well as other intermediates such as fructose and glyceraldehyde-3-phosphate, when present in high concentrations, promote the formation of advanced glycation endproducts (AGEs). These, in turn, can irreversibly cross link to proteins and cause intracellular aggregates that cannot be degraded by proteases and thereby, alter intracellular signalling.

Floyd John Lewis (1916 – September 20, 1993) was an American surgeon who performed the first successful open heart operation, closing an atrial septal defect in a 5-year-old girl, on 2 September 1952. For the next 3 years, Lewis and colleagues operated on 60 patients with atrial septal defects using hypothermia and inflow occlusion. He was best friends with C. Walton Lillehei and they worked together at the University of Minnesota. In 1956, Lewis moved on from Minnesota to Northwestern University where he became the first full- time member of the faculty of surgery.

Selumetinib can also cause serious side effects including heart failure (manifested as ejection fraction decrease, or when the muscle of the left ventricle of the heart is not pumping as well as normal) and eye toxicity (acute and chronic damage to the eye) including retinal vein occlusion, retinal pigment epithelial detachment and impaired vision. Cardiac and ophthalmic assessments should be performed prior to initiating selumetinib and at regular intervals during treatment. Selumetinib can also cause increased creatinine phosphokinase (CPK). CPK is an enzyme found in the heart, brain and skeletal muscles.

Portal hypertension is an absolute contraindication, as these patients are not surgical candidates and are at higher risk of significant complications from PVE. Additionally, complete lobar portal vein occlusion of either lobe would preclude expected increases in FLR from PVE due to already existing diversion of portal flow. Patients with extrahepatic metastatic disease are also not candidates for resection, and therefore PVE is contraindicated. In the past patients with bi-lobar disease were not considered for PVE, however now there may be a role of PVE in combination with a two-stage hepatectomy.

Seratrodast (development name, AA-2414; marketed originally as Bronica) is a thromboxane A2 (TXA2) receptor (TP receptor) antagonist used primarily in the treatment of asthma. It was the first TP receptor antagonist that was developed as an anti-asthmatic drug and received marketing approval in Japan in 1997. As of 2017 seratrodast was marketed as Bronica in Japan, and as Changnuo, Mai Xu Jia, Quan Kang Nuo in China. Unlike thromboxane synthase inhibitors such as ozagrel, seratrodast does not affect thrombus formation, time to occlusion and bleeding time.

In some parts of Malawi, it was quite common for women to adorn their lips with a lip disc called a "pelele" that by means of gradual enlargement from childhood could reach several inches of diameter and would eventually alter the occlusion of the jaw. Such lip stretching is still practiced in some places. Women of the Nilotic Mursi tribe in the Nile Valley wear lip rings on occasion that may reach in diameter. In some Pre-Columbian and North American cultures, labrets were seen as a status symbol.

This has resulted in many subtypes and new systems (see section below: Review of Angle's system of classes). A deep bite (also known as a Type II Malocclusion) is a condition in which the upper teeth overlap the lower teeth, which can result in hard and soft tissue trauma, in addition to an effect on appearance. It has been found to occur in 15-20% of the US population. An open bite is a condition characterised by a complete lack of overlap and occlusion between the upper and lower incisors.

Identifying the presence of tooth size discrepancies between the maxillary and mandibular arches is an important component of correct orthodontic diagnosis and treatment planning. To establish appropriate alignment and occlusion, the size of upper and lower front teeth, or upper and lower teeth in general, needs to be proportional. Inter-arch tooth size discrepancy (ITSD) is defined as a disproportion in the mesio-distal dimensions of teeth of opposing dental arches. The prevalence is clinically significant among orthodontic patients and has been reported to range from 17% to 30%.
|
|
Bolton developed a method to calculate the ratio between the mesiodistal width of maxillary and mandibular teeth and stated that a correct and harmonious occlusion is possible only with adequate proportionality of tooth sizes. Bolton's formula concludes that if in the anterior portion the ratio is less than 77.2% the lower teeth are too narrow, the upper teeth are too wide or there is a combination of both. If the ratio is higher than 77.2% either the lower teeth are too wide, the upper teeth are too narrow or there is a combination of both.

The Cook County coroner Andrew Toman attributed cause of death to an acute coronary occlusion."Mobster's Death Natural," New York Times, 1965, November 25. Humphreys' Oklahoma family, composed of Clemi, Llewella, and George, took a plane to Chicago and attended a private service at the Donnellan Funeral Home, where Humphreys' remains were cremated despite the wish he had expressed for his body to be donated for medical research. After the service Morrie Norman, having been a mutual friend of both Roemer and Humphreys, arranged a meeting between the family and Bill Roemer at his restaurant.

Prior to the cementation of the provisional crown, the occlusion should be checked. Any deficiencies in the provisional crown can be amended by the addition of more temporary crown and bridge material, or a light cured composite. If a temporary crown becomes decemented, it is important that a dentist examine the patient as overeruption of the opposing teeth may prevent accurate fitting of the final crown. If a dentist cannot be seen in a timely manner, the temporary crown may be recemented by applying temporary cement to the temporary crown.

Laser tattoo removal is painful - many patients say it is worse than getting the tattoo. The pain is often described to be similar to that of hot oil on the skin, or a "snap" from an elastic band. Depending on the patient's pain threshold, and while some patients may forgo anesthesia altogether, most patients will require some form of local anesthesia. Pre- treatment might include the application of an anesthetic cream under occlusion for 45 to 90 minutes or cooling by ice or cold air prior to the laser treatment session.

Both the Vedanta and the Zen-Buddhist tradition warn that insight into the emptiness of the self, or so-called "enlightenment experiences", are not sufficient; further practice is necessary. Jacobs warns that Advaita Vedanta practice takes years of committed practice to sever the "occlusion" of the so-called "vasanas, samskaras, bodily sheaths and vrittis", and the "granthi or knot forming identification between Self and mind". Zen Buddhist training does not end with kenshō, or insight into one's true nature. Practice is to be continued to deepen the insight and to express it in daily life.

The catheter is a foreign body in the vein and often provokes an inflammatory reaction in the vein wall. This results in scarring and narrowing of the vein, often to the point of occlusion. This can cause problems with severe venous congestion in the area drained by the vein and may also render the vein, and the veins drained by it, useless for creating a fistula or graft at a later date. Patients on long-term hemodialysis can literally 'run out' of access, so this can be a fatal problem.

This occlusion depended on denying the struggles for freedom waged by black people in the effort to expand the reach of freedom in the modern world. A danger of black suffering is that it could lead to a sense of pointlessness of black existence and a lack of self-worth. Cornel West has addressed the problem of Black Nihilism and its effect on the African-American community. > The proper starting point for the crucial debate about the prospects for > black America is an examination of the nihilism that increasingly pervades > black communities.

Displays of emotions can generally be categorized into two groups: negative and positive. Negative emotions usually manifest as increased tension in various muscle groups: tightening of jaw muscles, furrowing of forehead, squinting eyes, or lip occlusion (when the lips seemingly disappear). In contrast, positive emotions are revealed by the loosening of the furrowed lines on the forehead, relaxation of the muscles around the mouth, and widening of the eye area. When individuals are truly relaxed and at ease, the head will also tilt to the side, exposing our most vulnerable area, the neck.

The initial release of Gears of War Ultimate Edition suffered from significant display problems and stuttering on contemporary top-end hardware, leading to significant criticism of the developer and Microsoft's Universal Windows Platform. The problems partially related to the developer's transition of the game to DirectX 12 and the implementation of ambient occlusion. Driver updates and a patch from the studio significantly helped to address the issues. On Xbox One X, when video resolution is set to 4K UHD, Gears of War Ultimate Edition suffers from brightness, color, and sharpness fluctuations.

Other factors can cause glaucoma, known as "secondary glaucoma", including prolonged use of steroids (steroid-induced glaucoma); conditions that severely restrict blood flow to the eye, such as severe diabetic retinopathy and central retinal vein occlusion (neovascular glaucoma); ocular trauma (angle-recession glaucoma); and inflammation of the middle layer of the pigmented vascular eye structure (uveitis), known as uveitic glaucoma. laser Doppler imaging reveals arterial blood flow reversal in neovascular glaucoma. The color change of the Doppler image in the central retinal artery during the cardiac cycle indicates arterial flow reversal.

Like other related anomodonts, Parasuminia would have been a herbivore. Due to the similarity of the wear marks left on the teeth of Parasuminia to those of Suminia, it is likely that they both fed in a similar fashion with extensive tooth-on-tooth occlusion. Furthermore, although the jaw joint of Parasuminia is unknown, it can be inferred from the pattern of wear that Parasuminia was capable of a palinal jaw stroke to shred vegetation. This complex method of chewing is shared with both Suminia and the dicynodonts.

The Doctor is cared for by Shardovan, a librarian, and the elderly Portreeve, before Nyssa and Tegan arrive. After a night's sleep, they discover strange aspects of Castrovalva; if they go out of the town through any of its exits, they find themselves in a particular plaza in the town, and a tapestry in the Doctor's rooms changes and reflects events of the outside world. The Doctor understands that they are trapped in a "recursive occlusion", and Castrovalva is fake. The Portreeve reveals himself as the Master, and shows them the trapped Adric.

The procedure was performed by Lawson Tait in 1883 in women with a bleeding ectopic pregnancy; this procedure has since saved the lives of countless women. Other indications for a salpingectomy include infected tubes (as in a hydrosalpinx) or as part of the surgical procedure for tubal cancer. A bilateral salpingectomy will lead to sterility, and was used for that purpose; however, less invasive procedures have become available as tubal occlusion procedures. Prophylactic salpingectomy can be performed on women who are at a high risk of developing ovarian cancer.

The presence of Wellens' syndrome carries significant diagnostic and prognostic value. All people in the De Zwann's study with characteristic findings had more than 50% stenosis of the left anterior descending artery (mean = 85% stenosis) with complete or near-complete occlusion in 59%. In the original Wellens' study group, 75% of those with the typical syndrome manifestations had an anterior myocardial infarction. Sensitivity and specificity for significant (more or equal to 70%) stenosis of the LAD artery was found to be 69% and 89%, respectively, with a positive predictive value of 86%.

A stress echo assesses wall motion of the heart; it does not, however, create an image of the coronary arteries directly. Ischemia of one or more coronary arteries could cause a wall motion abnormality, which could indicate coronary artery disease. The gold standard test to directly create an image of the coronary arteries and directly assess for stenosis or occlusion is a cardiac catheterization. A stress echo is not invasive and is performed in the presence of a licensed medical professional, such as a cardiologist, and a cardiac sonographer.

The linea alba (Latin for white line), in dentistry, is a horizontal streak on the buccal mucosa (inner surface of the cheek), level with the occlusion (biting plane). It usually extends from the commissure to the posterior teeth, and can extend to the inner lip mucosa and corners of the mouth. The linea alba is a common finding and most likely associated with pressure, frictional irritation, or sucking trauma from the facial surfaces of the teeth. It may be mistaken for a lesion requiring treatment and may be found in individuals who chew tobacco.

In January 1952, Blake took a leave of absence to become the civilian technical director of the U.S. Army's Medical Research and Development Board. He did not hold the position long; at the end of that month he was admitted to Walter Reed Hospital for the treatment of a coronary occlusion, and on 1 February, he died. After his death, an award was established in his honor. The Francis Gilman Blake Award is an annual award to the Yale medical faculty member designated by the graduating class as the most outstanding teacher.

At the origin, after the separation of hot and cold, a ball of flame appeared that surrounded Earth like bark on a tree. This ball broke apart to form the rest of the Universe. It resembled a system of hollow concentric wheels, filled with fire, with the rims pierced by holes like those of a flute. Consequently, the Sun was the fire that one could see through a hole the same size as the Earth on the farthest wheel, and an eclipse corresponded with the occlusion of that hole.

Hanke stated that Niantic planned to allow third-party developers to build AR games similar to Pokémon Go. In June 2018, Niantic announced the acquisition of computer vision and machine learning company Matrix Mill. The Matrix Mill team has spent years focusing on perfecting augmented reality occlusion by building deep neural networks that can infer 3D information about the surrounding world. The acquisition significantly advances Niantic's efforts to deliver planet-scale AR and provide even more realistic AR experiences. In July 2018, Niantic announced the acquisition of LA-based gaming studio, Seismic Games.

Tourniquet cuff with a tie ribbon stabilizer Tourniquet cuff with a releasable application handle stabilizer Silicone ring tourniquets, or elastic ring tourniquets, are self-contained mechanical devices that do not require any electricity, wires or tubes. The tourniquet comes in a variety of sizes. To determine the correct product size, the patient's limb circumference at the desired occlusion location should be measured, as well as their blood pressure to determine the best model. Once the correct model is selected, typically two sterile medical personnel will be needed to apply the device.

However, no other signs are present except those involved in changes in occlusion intraorally such as pain, and the enlargement corresponds with the outline of the muscle. Most patients seek medical attention because of comments about facial appearance, and this situation may be associated with further pathology of the temporomandibular joint.Illustrated Anatomy of the Head and Neck, Fehrenbach and Herring, Elsevier, 2012, p. 97 Finally, the muscle undergoes spasm with malignant hyperthermia as do other skeletal muscles, but this one is easily noted, since it is on the face.

They were first described by Robert Walter Doyne in 1889 in a patient with retinal hemorrhages. In 1892, ophthalmologist Hermann Jakob Knapp called them "angioid streaks" because of their resemblance to blood vessels. From histopathological research in the 1930s, they were discovered to be caused by changes at the level of Bruch's membrane. Presently, it is believed that its pathology may be a combination of elastic degeneration of Bruch's membrane, iron deposition in elastic fibers from hemolysis with secondary mineralization, and impaired nutrition due to stasis and small vessel occlusion.

Mechanical removal of the blood clot causing the ischemic stroke, called mechanical thrombectomy, is a potential treatment for occlusion of a large artery, such as the middle cerebral artery. In 2015, one review demonstrated the safety and efficacy of this procedure if performed within 12 hours of the onset of symptoms. It did not change the risk of death, but reduced disability compared to the use of intravenous thrombolysis which is generally used in people evaluated for mechanical thrombectomy. Certain cases may benefit from thrombectomy up to 24 hours after the onset of symptoms.

Radiograph images, before and after the procedure are used to evaluate the outcome of the treatment. The patients are scheduled to follow up at 3, 6, 9, and 12 months after the completion of therapy. The tooth is accessed for different aspects such as pain, swelling, sinus tract, mobility, tooth discoloration, and the occlusion relationship. At the 12-month follow-up, CBCT images are taken to analyze the root development, in specific to access for the disappearance of apical radiolucency, increase of root length or a decrease of the apical foramen, or both.

In the oral and maxillofacial area, such a displacement could have a major effect both on facial aesthetics and organ function: a fracture occurring in a bone that delimits the orbit can lead to diplopia; a mandibular fracture can induce significant modifications of the dental occlusion; in the same manner, a skull (neurocranium) fracture can produce an increased intracranial pressure. In severe congenital malformations of the facial skeleton surgical creation of usually multiple bone segments is required with precise movement of these segments to produce a more normal face.

According to the World Health Organization "Evidence suggests that podoconiosis is the result of a genetically determined abnormal inflammatory reaction to mineral particles in irritant red clay soils derived from volcanic deposits". The pathophysiology of podoconiosis is a combination of genetic susceptibility, possibly through associations with HLA-DQA1, HLA-DQB1, and HLA-DRB1 variants, and a cumulative exposure to irritant soil. In susceptible individuals, irritant soil particles penetrate the feet and collect in lymphatic vessels. Over time, chronic inflammation within the lymphatic vessels leads to fibrosis and occlusion.

There are several therapies that can be used to correct a posterior crossbite: braces, 'Z' spring or cantilever spring, quad helix, removable plates, clear aligner therapy, or a Delaire mask. The correct therapy should be decided by the orthodontist depending on the type and severity of the crossbite. One of the keys in diagnosing the anterior crossbite due to skeletal vs dental causes is diagnosing a CR-CO shift in a patient. An adolescent presenting with anterior crossbite may be positioning their mandible forward into centric occlusion (CO) due to the dental interferences.

This can reduce the maximum output pressure during pumping. This differs from many other pumps as they commonly reduce flow to reduce pressure in a given circumstance, however if an occlusion occurs to the output channel other pumps tend to build up to their maximum pressure until they either burst the tubing or damage their internal mechanism. Inductive pumps can be shut off at the outlet and will not exceed the pressure they are set at. Pumping against a closed output does not cause damage to the pump.

Antley–Bixler syndrome presents itself at birth or prenatally. Features of the disorder include brachycephaly (flat forehead), craniosynostosis (complete skull-joint closure) of both coronal and lambdoid sutures, facial hypoplasia (underdevelopment); bowed ulna (forearm bone) and femur (thigh bone), synostosis of the radius (forearm bone), humerus (upper arm bone) and trapezoid (hand bone); camptodactyly (fused interphalangeal joints in the fingers), thin ilial wings (outer pelvic plate) and renal malformations. Other symptoms, such as cardiac malformations, proptotic exophthalmos (bulging eyes), arachnodactyly (spider-like fingers) as well as nasal, anal and vaginal atresia (occlusion) have been reported.

A coronary catheterization is a minimally invasive procedure to access the coronary circulation and blood filled chambers of the heart using a catheter. It is performed for both diagnostic and interventional (treatment) purposes. Coronary catheterization is one of the several cardiology diagnostic tests and procedures. Specifically, through the injection of a liquid radiocontrast agent and illumination with X-rays, angiocardiography allows the recognition of occlusion, stenosis, restenosis, thrombosis or aneurysmal enlargement of the coronary artery lumens; heart chamber size; heart muscle contraction performance; and some aspects of heart valve function.

Although pulmonary arterial pressure (PAP) can be estimated on the basis of echocardiography, pressure measurements with a Swan-Ganz catheter inserted through the right side of the heart provide the most definite assessment.[42] Pulmonary hypertension is defined as a mean PAP of at least 20 mm Hg (3300 Pa) at rest, and PAH is defined as precapillary pulmonary hypertension (i.e. mean PAP ≥ 20 mm Hg with pulmonary arterial occlusion pressure [PAOP] ≤ 15 mm Hg and pulmonary vascular resistance [PVR] > 3 Wood Units). PAOP and PVR cannot be measured directly with echocardiography.

Multi piece osteotomy is performed when there is a notable residual alveolar defect with a dental gap and oronasal fistula (communication between the oral and nasal cavities). The goal of both single and multi piece osteotomy is to displace the maxilla forward to obtain adequate occlusion as well to provide better support for upper lip and the nose and to close any fistulae. Distraction osteogenesis – bone lengthening by gradual distraction. This involves cutting bone and moving ends apart incrementally to allow new bone to form in the gap.

Unigine renderer supports shader model 5.0 with hardware tessellation and DirectCompute (as well as OpenCL), together with a set of post-processes, including screen space ambient occlusion (SSAO), and real-time global illumination. There is a set of built-in high-level objects like terrain, grass, water, clouds and so on. Unigine uses a proprietary physics engine (collision detection, rigid body physics, dynamical destruction of objects, rag doll, cloth, fluid buoyancy, force fields, time reverse). Pathfinding is also implemented with a proprietary engine, together with basic AI components (spatial triggers, callbacks).

Polyvinylsiloxane impression material is one of several very accurate impression materials used when the final impression is taken of the maxillary and mandibular ridges. A wax rim is fabricated to assist the dentist or denturist in establishing the vertical dimension of occlusion. After this, a bite registration is created to marry the position of one arch to the other. Once the relative position of each arch to the other is known, the wax rim can be used as a base to place the selected denture teeth in correct position.

In vision therapy of amblyopia and of intermittent central suppression, liquid crystal devices have been used for purposes of enhanced occlusion therapy. In this scenario, the amblyopic patient wears electronically programmable liquid crystal glasses or goggles for continuously for several hours during regular everyday activities. Wearing the device encourages or forces the patient to use both eyes alternatingly, similar to eye patching, but rapidly alternating in time. The aim is to circumvent the patient's tendency to suppress the field of view of the weaker eye and to train the patient's capacity for binocular vision.

Immediately following coronary artery or neurosurgical vascular bypass surgery, patients recover in an intensive care unit or coronary care unit for one to two days. Provided that recovery is normal and without complications, they can move to a less intensively monitored unit such as a step-down unit or a ward bed. Depending on the extent of the surgery, recovery from a leg bypass may start from a step-down or ward bed. Monitoring immediately after bypass surgery focuses on signs and symptoms of bleeding and graft occlusion.

Gysi's geometrical concept underpinned bilateral occlusion schemes for both edentulous and dentate patients. Bizarrely, the theory was based on scratch- marks created using a simulated sharks' teeth model recorded on an opposing plaster cast. Gysi utilised a simulated shark's teeth model to illustrate bilateral occlusal schemes in both edentulous and dentate patients. From the above observation, 33° 'cuspal formed' teeth were introduced such that the cuspal inclination would be parallel with the condylar angle in the sagittal/horizontal plane when set-up mid-way between the condyle and incisors.

When stasis occurs, the procedure is terminated and a final arteriogram is performed to document occlusion of the target vessel and preservation of the blood flow to non-target vessels. For solitary tumors, an attempt is made to embolize the tumor as selectively as possible. The initial arteriogram is reviewed to determine which vessel or vessels are feeding the tumor. Each vessel is then selected, typically with a coaxial 2F or 3F catheter, and that vessel is embolized with up to 10 mL of the smallest- size particles.

Historically, many believed that problems with the bite were the sole cause for bruxism. It was often claimed that a person would grind at the interfering area in a subconscious, instinctive attempt to wear this down and "self equiliberate" their occlusion. However, occlusal interferences are extremely common and usually do not cause any problems. It is unclear whether people with bruxism tend to notice problems with the bite because of their clenching and grinding habit, or whether these act as a causative factor in the development of the condition.

Some research indicates calculating "area stenosis" is also a valid measure of actual vessel stenosis compared to diameter stenosis alone, but this requires additional analysis because a tracing of the lumen border must be performed. However, there are computer programs available to automatically perform this function. It may be helpful to obtain both percent diameter and area percent stenosis, especially since the two percentages may not always correlate with each other. An occlusion, or the blocking of all blood flow through a vessel, is considered 100% percent diameter stenosis.

The surfaces of the scene to be rendered are each divided up into one or more smaller surfaces (patches). A view factor (also known as form factor) is computed for each pair of patches; it is a coefficient describing how well the patches can see each other. Patches that are far away from each other, or oriented at oblique angles relative to one another, will have smaller view factors. If other patches are in the way, the view factor will be reduced or zero, depending on whether the occlusion is partial or total.

In tenuis plosives, the vocal cords come together for voicing immediately following the release, and there is little or no aspiration (a voice onset time close to zero). In English, there may be a brief segment of breathy voice that identifies the plosive as voiceless and not voiced. In voiced plosives, the vocal folds are set for voice before the release, and often vibrate during the entire hold, and in English, the voicing after release is not breathy. A plosive is called "fully voiced" if it is voiced during the entire occlusion.

Under Zinn's leadership, Micrel was profitable in its first year, and for 36 of its 37 years. Zinn credits this success to the company's disciplined focus on profitability. Micrel was also credited with having the lowest employee turn-over in the semiconductor industry and, though it is an unofficial measure, the highest "boomerang" employee rate, the rate at which employees who leave the company return. During an investor "roadshow" promoting Micrel's initial public offering in London, England, Zinn suffered a retinal vein occlusion which reduced his vision to 20/400, making Zinn legally blind.

While a full testing of tubal functions in patients with infertility is not possible, testing of tubal patency is feasible. A hysterosalpingogram will demonstrate that tubes are open when the radioopaque dye spills into the abdominal cavity. Sonography can demonstrate tubal abnormalities such as a hydrosalpinx indicative of tubal occlusion. During surgery, typically laparoscopy, the status of the tubes can be inspected and a dye such as methylene blue can be injected in a process termed chromotubation into the uterus and shown to pass through the tubes when the cervix is occluded.

In early 1726, she suffered a stroke; in August of that year she went to bed with a severe colic, and never rose again, refusing all food and treatment. Within a few weeks she grew emaciated. Sophia Dorothea died shortly before midnight on 13 November 1726 aged 60; her autopsy revealed a liver failure and gall bladder occlusion due to 60 gallstones. Her former husband placed an announcement in The London Gazette to the effect that the "Duchess of Ahlden" had died, but forbade mourning in London or Hanover.

Molars and premolars that have had root canal therapy should be protected with a crown that covers the cusps of the tooth. This is because the access made into the root canal system removes a significant amount of tooth structure. Molars and premolars are the primary teeth used in chewing and will almost certainly fracture in the future without cuspal coverage. Anterior teeth typically do not require full coverage restorations after a root canal procedure, unless there is extensive tooth loss from decay or for esthetics or unusual occlusion.

From greatest to least stricture, speech sounds may be classified along a cline as stop consonants (with occlusion, or blocked airflow), fricative consonants (with partially blocked and therefore strongly turbulent airflow), approximants (with only slight turbulence), and vowels (with full unimpeded airflow). Affricates often behave as if they were intermediate between stops and fricatives, but phonetically they are sequences of a stop and fricative. Over time, sounds in a language may move along the cline toward less stricture in a process called lenition or towards more stricture in a process called fortition.

In the differential diagnosis of LFS, another disorder that exhibits some features and symptoms of LFS and is also associated with a missense mutation of MED12 is Opitz-Kaveggia syndrome (FGS). Common features shared by both LFS and FGS include X-linked intellectual disability, hyperactivity, macrocephaly, corpus callosum agenesis and hypotonia. Notable features of FGS that have not been reported with LFS include excessive talkativness, consistent strength in socialization skills, imperforate anus (occlusion of the anus) and ocular hypertelorism (extremely wide-set eyes). Whereas LFS is associated with missense mutation p.

A. Marc Gillinov is an American cardiac surgeon at The Cleveland Clinic He did his undergraduate work at Yale University and obtained his medical degree from The Johns Hopkins University School of Medicine, and joined the Cleveland Clinic staff in 1997. Inventions made by Gillinov, along with those of another surgeon, Edward M. Boyle, formed the basis for a wound drainage product brought to market by ClearFlow. He worked on a device for left atrial appendage occlusion sold by AtriCure. He wrote a book with Steven Nissen that published in 2012.

The dental morphology of Vilevolodon is characterized by a dual “mortar-and-pestle” occlusion of molars in which the tallest distal cusp of the upper molar occludes into the deepest distal basin of the opposite, lower molar. The tallest mesial cusp of the lower molar occludes into the mesial basin of the opposite upper molar, simultaneously. Analysis using STL models and tomography scans suggest that this occlusal pattern allows for a complex mechanism of dual crushing and grinding capabilities. A similar occlusal pattern is seen in other Haramiyids, Arboroharamiya and Xianshou.

Gemtuzumab is a monoclonal antibody to CD33 linked to a cytotoxic agent from the class of calicheamicins. CD33 is expressed in most leukemic blast cells but also in normal hematopoietic cells, the intensity diminishing with maturation of stem cells. Common side effects of administration included shivering, fever, nausea and vomiting. Serious side effects included severe myelosuppression (suppressed activity of bone marrow, which is involved in formation of various blood cells [found in 98% of patients]), disorder of the respiratory system, tumor lysis syndrome, Type III hypersensitivity, venous occlusion, and death.

P2C ATPases (or Type IIC) include the closely related Na+/K+ and H+/K+ ATPases from animal cells. (TC# 3.A.3.1) The X-ray crystal structure at 3.5 Å resolution of the pig renal Na+/K+-ATPase has been determined with two rubidium ions bound in an occluded state in the transmembrane part of the α-subunit. Several of the residues forming the cavity for rubidium/potassium occlusion in the Na+/K+-ATPase are homologous to those binding calcium in the Ca2+-ATPase of the sarco(endo)plasmic reticulum.

The complications described in the literature have been rare: hemorrhage from damage to the veins at the time of the procedure; and fetal death due to uterine vessels occlusion. No significant differences in pregnancy outcomes were found in a study evaluating pregnancy outcomes after cervical conization. This study suggests for women with cervical insufficiency due to prior cone biopsy, cerclage is not superior to no intervention. As cerclage can induce preterm contractions without preventing premature delivery, makes the recommendation that it be used sparingly in women with a history of conization.

Over a period of eight months, the appliance was worn 24 hours a day and over time enough space was created to allow the application of palatal gold inlays to the worn upper incisors. Dahl found that it was a combination of intrusion of the anterior teeth in contact with the appliance (40%) and passive eruption of the unopposed posterior teeth (60%) that permitted the reestablishment of posterior occlusion whilst maintaining the interocclusal space.dahl b l, krogstad o.

In a letter to the International Journal of Cardiology, Tsung O. Cheng called out his own field as prone to overuse of contrived acronyms, calling it a "persistent problem". He was spurred to write the letter after he reviewed nine articles about a study named "ZAHARA" without finding any explanation of what the acronym meant. Other clinical trials that have been noted in publications for their acronyms include: TORPEDO (Thrombus Obliteration by Rapid Percutaneous Endovenous Intervention (PEVI) in Deep Venous Occlusion) and BATMAN (Bisphosphonate and Anastrozole Trial – Bone Maintenance Algorithm Assessment).

Since the vertebral body in a retrolisthesis moves in a posterior direction, the grading used for spondylolistheses is of little use. It is however useful to divide the anterior to posterior dimension of the intervertebral foramina (IVF) (4) into four equal units. A posterior displacement of up to ¼ of the IVF is graded as Grade 1, ¼ to ½ as Grade 2, ½ to ¾ as Grade 3, ¾ to total occlusion of the IVF as Grade 4. Alternatively, a measurement of the amount of displacement can also made by measuring the bone displacement in millimetres.

A 2015 review found the effectiveness of Essure is unclear due to the low quality of evidence. With perfect use another review found evidence of a 99.8% effective based on 5 years of follow-up. The reported insertional failure rates are "failure to place 2 inserts in the first procedure (5%), initial tubal patency (3.5%), expulsion (2.2%), perforation (1.8%), or other unsatisfactory device location (0.6%)". Upon follow-up, occlusion was observed to have occurred in 96.5% of patients at 3 months with the remainder occluded by 6 months.

Subclavian steal syndrome (SSS), also called subclavian steal phenomenon or subclavian steal steno-occlusive disease, is a constellation of signs and symptoms that arise from retrograde (reversed) blood flow in the vertebral artery or the internal thoracic artery, due to a proximal stenosis (narrowing) and/or occlusion of the subclavian artery. The arm may be supplied by blood flowing in a retrograde direction down the vertebral artery at the expense of the vertebrobasilar circulation. This is called the subclavian steal. It is more severe than typical vertebrobasilar insufficiency.

In addition to reestablishing a protected occlusion, these prostheses can greatly improve one's chewing abilities. As a consequence of a lack of certain nutrition due to altered eating habits, various health problems can occur, from the mild to the extreme. Lack of certain vitamins (A, E and C) and low levels of riboflavin and thiamin can produce a variety of conditions, ranging from constipation, weight loss, arthritis and rheumatism. There are more serious conditions such as heart disease and Parkinson's disease and even to the extreme, certain types of Cancer.

In 2013 and 2014, the game participated in Google Summer of Code as a mentoring organization. The migration of the code repository from Sourceforge to GitHub was officially announced on 17 January 2014, though the assets repository and downloads remain on Sourceforge. On April 21, 2015, version 0.9 was released which used a highly modified version of Irrlicht, including an entirely new graphics renderer dubbed Antarctica. This enabled much better graphics with features such as dynamic lighting, ambient occlusion, depth of field, real-time shadow mapping, and more.

Lipohyalinosis is a cerebral small vessel disease affecting the small arteries, arterioles or capillaries in the brain. Originally defined by C. Miller Fisher as 'segmental arteriolar wall disorganisation', it is characterized by vessel wall thickening and a resultant reduction in luminal diameter. Fisher considered this small vessel disease to be the result of hypertension, induced in the acute stage by fibrinoid necrosis that would lead to occlusion and hence lacunar stroke. However, recent evidence suggests that endothelial dysfunction as a result of inflammation is a more likely cause for it.

Occlusion of blood vessels that supply the nerves or their nuclei, an ischemic stroke, may cause specific signs and symptoms relating to the damaged area. If there is a stroke of the midbrain, pons or medulla, various cranial nerves may be damaged, resulting in dysfunction and symptoms of a number of different syndromes. Thrombosis, such as a cavernous sinus thrombosis, refers to a clot (thrombus) affecting the venous drainage from the cavernous sinus, affects the optic (II), oculomotor (III), trochlear (IV), opthalamic branch of the trigeminal nerve (V1) and the abducens nerve (VI).

With regard to the graphical updates introduced in this patch, the PC platform was given a new weapon debris effect and a new ambient occlusion setting. The patch fixed several bugs and glitches present in the game. Patch 1.4 was designed to ready the game for the upcoming Creation Kit and downloadable content. Patch 1.4 brought a variety of additions to the settlement building mechanic of the game by adding a symbol to new content placed in by the modding community along with adding a variety of items, such as Raider and Super Mutant decors.

Angioplasty requires an access vessel, typically the femoral or radial artery or femoral vein, to permit access to the vascular system for the wires and catheters used. If no access vessel of sufficient size and quality is available, angioplasty is contraindicated. A small vessel diameter, the presence of posterior calcification, occlusion, hematoma, or an earlier placement of a bypass origin, may make access to the vascular system too difficult. Percutaneous transluminal coronary angioplasty (PTCA) is contraindicated in patients with left main coronary artery disease, due to the risk of spasm of the left main coronary artery during the procedure.

The most significant issue regarding the Todd's paresis is its differentiation from a stroke. The issue is further complicated by the fact that some strokes trigger a focal seizure during the acute phase. A Todd's paresis in this context may overestimate the extent of neurological deficit due to the vascular process itself resulting in erroneous decisions with regards to acute stroke therapy such as thrombolysis. For this reason a seizure during an acute stroke is generally accepted to be a relative contraindication to thrombolytic therapy, especially in the absence of documented cerebrovascular occlusion using vascular imaging techniques.

Abfraction has been a controversial subject since its creation in 1991. This is due to the clinical presentation of the tooth loss, which often presents in a manner similar to that of abrasion or erosion. The major reasoning behind the controversy is the similarity of abfraction to other non carious lesions and the prevalence of multiple theories to potentially explain the lesion. One of the most prevalent theories is called "the theory of non-carious cervical lesions" which suggests that tooth flexion, occurring due to occlusion factors, impacts on the vulnerable area near the cementoenamel junction.

The eight front teeth are spatulate and peg-like, and served as incisors that were used to nip off mouthfuls of vegetation. The broad, blunt cheek teeth show extensive wear associated with occlusion, and would have functioned as molars, grinding up the food. It also had a partial secondary palate, which meant it could chew its food and breathe at the same time, something many even more advanced reptiles were unable to do. These traits are likely adaptations related to the animals' high-fiber, herbivorous diet, and evolved independently of similar traits seen in some reptilian groups.

Angiography is commonly used in the diagnosis of Takayasu arteritis, especially in the advanced stages of the disease, when arterial stenosis, occlusion, and aneurysms may be observed. However, angiography is a relatively invasive investigation, exposing patients to large doses of radiation, so is not recommended for routine, long-term monitoring of disease progression in patients with Takayasu arteritis. Computed tomography angiography can determine the size of the aorta and its surrounding branches, and can identify vessel wall lesions in middle to late stages of arteritis. CTA can also show the blood flow within the blood vessels.

Occlusion of the middle cerebral artery results in Middle cerebral artery syndrome, potentially showing the following defects: # Paralysis (-plegia) or weakness (-paresis) of the contralateral face and arm (faciobrachial) # Sensory loss of the contralateral face and arm. # Damage to the dominant hemisphere (usually the left hemisphere) results in aphasia i.e. Broca's area or Wernicke's # Damage to the non-dominant hemisphere (usually the right hemisphere) results in contralateral neglect syndrome # Large MCA infarcts often have déviation conjuguée, a gaze preference towards the side of the lesion, especially during the acute period. Contralateral homonymous hemianopsia is often present.

Hypertension is also associated with impaired cognition in an aging population. Hypertension- related cognitive impairment and dementia may be a consequence of a single infarct due to occlusion of a "strategic" larger vessel or multiple lacunar infarcts due to occlusive small vessel disease resulting in subcortical white matter ischemia. Several clinical trials suggest that antihypertensive therapy has a beneficial effect on cognitive function, although this remains an active area of investigation. Cerebral blood flow remains unchanged over a wide range of arterial pressures (mean arterial pressure of 50–150 mmHg) through a process termed autoregulation of blood flow.

Kenneth Anderson, "Telos, the critical theory journal and its blog," November 18, 2007. With the disintegration of the New Left and the gradual integration of what remained of the American Left within the Democratic Party, Telos became increasingly critical of the Left in general. It subsequently undertook a reevaluation of 20th century intellectual history, focusing primarily on forgotten and repressed authors and ideas, beginning with Carl Schmitt and American populism. Eventually the journal rejected the traditional divisions between Left and Right as a legitimating mechanism for new class domination and an occlusion of new, post-Fordist political conflicts.

A result of between 3–5 seconds is equivocal, whereas the radial artery will not be considered for grafting if the result is longer than 5 seconds. The utility of the modified Allen's test is questionable, and no direct correlation with reduced ischemic complications of radial artery cannulation have ever been proven. In 1983, Slogoff and colleagues reviewed 1,782 radial artery cannulations and found that 25% of them resulted in complete radial artery occlusion, without apparent adverse effects. A number of reports have been published in which permanent ischemic sequelae occurred even in the presence of a normal Allen's test.

The symptoms of ocular MG can also be addressed by non-medicinal means. Ptosis can be corrected with placement of crutches on eyeglasses and with ptosis tape to elevate eyelid droop. Diplopia can be addressed by occlusion with eye patching, frosted lens, occluding contact lens, or by simply placing opaque tape over a portion of eyeglasses. Also, plastic prisms (Fresnel prisms) can be attached to eyeglasses of a diplopic patient, allowing for alignment of vision from both eyes in the affected direction, but are often problematic if the degree of muscle weakness, and therefore ocular misalignment, fluctuates frequently.

These areas probably had a horny covering in life. The broad groove running along the tooth row on the dentary was probably also covered by a horny layer. It is possible that these regions allowed for occlusion where the upper teeth met the groove lateral to the lower teeth and the lower teeth met one of the regions of the palatine. This is still under scrutiny as the palatine region is short in comparison to the lower tooth row and the second horn covered area on the palatine does not oppose any structure in the lower jaw.

West Terrace AIF Cemetery, Adelaide After returning from the war, Davey worked for South Australian Railways as a labourer and linesman over three periods between 1926 and 1946: 27 April 1926 to 4 October 1938; 6 March 1939 to 12 February 1942; and 17 December 1943 to 22 February 1946. He married Eugene Agnes Tomlinson on 25 August 1928; they had no children. After suffering for many years with bronchitis and emphysema, Davey died on 21 December 1953 of a coronary occlusion. He was buried at the West Terrace AIF Cemetery, Adelaide, with full military honours.

People whose CT scan shows a large hematoma, depressed level of consciousness, or focal neurologic signs may benefit from urgent surgical removal of the blood or occlusion of the bleeding site. The remainder are stabilized more extensively and undergo a transfemoral angiogram or CT angiogram later. It is hard to predict who will have a rebleed, yet it may happen at any time and carries a dismal prognosis. After the first 24 hours have passed, rebleeding risk remains around 40 percent over the subsequent four weeks, suggesting that interventions should be aimed at reducing this risk as soon as possible.

It is before and before and , perhaps because labialization is constrained by the spread front vowels; it does not occur before the back (rounded) vowels and . It is doubted by some scholars that true closure can be made by a labiodental gesture because of gaps between the incisors, which for many speakers would allow air to flow during the occlusion. This is particularly pertinent considering that one of the Kukuya words with this consonant, , means a 'gap between filed incisors,' a practice of the local people. The might therefore be better characterized as a labiodental nasal approximant than as a nasal occlusive.

Retinal haemorrhage is a disorder of the eye in which bleeding occurs in the retina, the light sensitive tissue, located on the back wall of the eye. There are photoreceptor cells in the retina called rods and cones, which transduce light energy into nerve signals that can be processed by the brain to form visual images. Retinal hemorrhage can affect adults, and newborn babies and infants may also suffer from this disorder. A retinal hemorrhage can be caused by several medical conditions such as hypertension, retinal vein occlusion (a blockage of a retinal vein), anemia, leukemia or diabetes.

Currently, treatment for acute ischemic stroke due to an occlusion of one of the arteries of the proximal anterior intracranial circulation consists of intravenous thrombolysis followed by endovascular thrombectomy for patients that arrive at the hospital within 4.5 hours of stroke onset. Patients that arrive later than 4.5 hours after onset, or have contra-indications for intravenous thrombolysis can still be eligible for endovascular thrombectomy only. Even with treatment, not all patients recover after their stroke; many are left with permanent brain damage. Increased thrombus perviousness may decrease brain damage during stroke by allowing more blood to reach the ischemic tissue.

The liver is unique in that it is an organ with regenerative potential. When blood flow to one section of the liver is occluded in PVE, the flow is diverted to other areas and this increase in blood flow stimulates the regenerative response. Regeneration begins within hours of occlusion and factors important to this response include hepatocyte growth factor, epidermal growth factor, insulin, IL-6 and TNF-alpha, among others. The expected increase in FLR is approximately 10 percent; greater increases after four to six weeks can be observed, albeit at a lower rate of growth.

A water buffalo chewing cud Chewing is primarily an unconscious (semi-autonomic) act, but can be mediated by higher conscious input. The motor program for mastication is a hypothesized central nervous system function by which the complex patterns governing mastication are created and controlled. It is thought that feedback from proprioceptive nerves in teeth and the temporomandibular joints govern the creation of neural pathways, which in turn determine duration and force of individual muscle activation (and in some cases muscle fiber groups as in the masseter and temporalis). This motor program continuously adapts to changes in food type or occlusion.

Her work has been translated to various languages, including Italian, German, and Portuguese. As a composer, four emblematic songs can be mentioned that are pertinent to popular Uruguayan music: A una paloma (performed by Daniel Viglietti), La canción y el poema (performed by Alfredo Zitarrosa), Los orientales, and Ya me voy pa' la guerrilla (performed by Los Olimareños). In 2004, she received the Premio Konex (Konex prize) MERCOSUR a las Letras, granted by the Konex Foundation (Argentina), as the most influential writer of the region. Later, she had to undergo surgery that left her with an intestinal and arterial occlusion.

Longer descriptors continue to do better but not by much and there is an additional danger of increased sensitivity to distortion and occlusion. It is also shown that feature matching accuracy is above 50% for viewpoint changes of up to 50 degrees. Therefore, SIFT descriptors are invariant to minor affine changes. To test the distinctiveness of the SIFT descriptors, matching accuracy is also measured against varying number of keypoints in the testing database, and it is shown that matching accuracy decreases only very slightly for very large database sizes, thus indicating that SIFT features are highly distinctive.

Additionally, interventional cardiology procedure of primary angioplasty is now the gold standard of care for an acute Myocardial infarction. This procedure can also be done proactively, when areas of the vascular system become occluded from Atherosclerosis. The Cardiologist will thread this sheath through the vascular system to access the heart. This sheath has a balloon and a tiny wire mesh tube wrapped around it, and if the cardiologist finds a blockage or Stenosis, they can inflate the balloon at the occlusion site in the vascular system to flatten or compress the plaque against the vascular wall.

This is based on the Frank-Starling law of the heart. Healthy patients should be able to compensate for lower volumes to some extent, but patients with pre-existing cardiovascular disease limiting myocardial function (such as angina pectoris) may not. Applying permissive hypotension to the latter patient category may result in decreased coronary perfusion and result in ischemic damage to the heart and potentially myocardial infarction (heart attack). Permissive hypotension may also be contraindicated in patients with cerebrovascular disease, carotid artery stenosis, and compromised renal (kidney) function, where hypotension may induce sludge (thickening of blood) and lead to occlusion of the vessel lumen.

J Postgrad Med 2008;54:54-7. The sign was first described by Warren Tay, founding member of the British Ophthalmological Society, in 1881, with reference to a patient with Tay–Sachs disease. The cherry red spot is seen in central retinal artery occlusion, appearing several hours after the blockage of the retinal artery occurs.Rakel, Robert E., Textbook of Family Medicine, 7th ed, Chapter 53 The cherry red spot is seen because the macula receives its blood supply from the choroid, supplied by the long and short posterior ciliary arteries, while the surrounding retina is pale due to retinal artery infarction.

Of the 53 implantations, complete closure occurred immediately in 71% of patients, and 100% after six months. Findings are generally very positive, although the erosion rate is not yet known. In August 2014 it was announced that Freudenthal had won the "Innovators of America" award in the Science and Technology category for his occlusion device to cure congenital heart disease in children. The award is given by Innovative America, is sponsored by the CAF – Development Bank of Latin America and the Spanish CAF Ezentis group, and was to be presented in Medellín, Colombia on 21 August 2014.

The infarct generally results grossly in a wedge shaped area of necrosis with the apex closest to the occlusion and the base at the periphery of the organ. The margins will become better defined with time with a narrow rim of congestion attributable to inflammation at the edge of the lesion.Robbins Basic Pathology Relatively few extravasated red cells are lysed so the resulting hemosiderosis is limited and results in a progressively more pale area of infarction with time. Ischemic coagulative necrosis results and fibrosis of the affected area develops from the reparative response beginning at the preserved margins and working its way inwards.

The dentary is peculiarly curved, making it a characteristic of this genus. The peculiar twist is designed to swing the posterior lower cheek teeth inward to ensure proper occlusion on the upper teeth. The dentary is greatly thickened, both internally and externally along the series of cheek teeth, much more than the transversely broadened teeth and their roots demand. The posterior part of the dental row is displaced inward so the dorsal margin of the coronoid process descends some distance laterally to the hindmost teeth and continues down and forward across the lateral face of the dentary virtually to the chin.

This procedure involves the ligation or otherwise occlusion of the umbilical cord to interrupt the exchange of blood between the fetuses. The procedure is typically offered in cases where one of the fetuses is presumed moribund and endangering the life or health of the other twin through resultant hypotension. Use of this treatment has decreased as TTTS is identified and treated in earlier stages and with better outcomes. When used, it is associated with an 85% survival rate of the remaining fetus(es) with 5% risk of cerebral palsy and a 33–39 weeks of gestation at delivery.

3D still showing normal heart vs heart failure. A myocardial infarction may compromise the function of the heart as a pump for the circulation, a state called heart failure. There are different types of heart failure; left- or right-sided (or bilateral) heart failure may occur depending on the affected part of the heart, and it is a low-output type of failure. If one of the heart valves is affected, this may cause dysfunction, such as mitral regurgitation in the case of left-sided coronary occlusion that disrupts the blood supply of the papillary muscles.

Periodontal fremitus occurs in either of the alveolar bones when an individual sustains trauma from occlusion. It is a result of teeth exhibiting at least slight mobility rubbing against the adjacent walls of their sockets, the volume of which has been expanded ever so slightly by inflammatory responses, bone resorption or both. As a test to determine the severity of periodontal disease, a patient is told to close his or her mouth into maximum intercuspation and is asked to grind his or her teeth ever so slightly. Fingers placed in the labial vestibule against the alveolar bone can detect fremitus.

Left atrial appendage occlusion is an experimental alternative to anticoagulants. During cardiac catheterization, a device (such as the Watchman device) consisting of an expandable nitinol frame is introduced into the left atrial appendage, the source of blood clots in more than 90% of cases. A trial comparing closure against warfarin therapy found closure to be non-inferior when measured against a composite end point of stroke, cardiovascular death and systemic embolism. The left atrial appendage can also be surgically amputated, sutured or stapled simultaneously with other cardiac procedures such as a maze procedure or during mitral valve surgery.

In 3D computer graphics, hidden-surface determination (also known as shown- surface determination, hidden-surface removal (HSR), occlusion culling (OC) or visible-surface determination (VSD)) is the process of identifying what surfaces and parts of surfaces can be seen from a particular viewing angle. A hidden-surface determination algorithm is a solution to the visibility problem, which was one of the first major problems in the field of 3D computer graphics . The process of hidden-surface determination is sometimes called hiding, and such an algorithm is sometimes called a hider. When referring to line rendering it is known as hidden-line removal.

The American Dental Association and Canadian Dental Association have not been invited to participate in the development of this device as it does not affect teeth or occlusion; although the device is fit within the mouth, the Angellift devices affect the skin surface and not the perioral cavity. The Angellift devices are cleaned in similar fashion as retainers or dentures. In 2008 Angellift introduced an over-the-counter version of the original prescriptive model which could only be fit by dentists. The over-the-counter version does not require a dental visit as it does not attach to the teeth.

The ITRI was established in 1992 by Haeger which utilises both intra-arch and inter-arch relationships to generate index scores to compare the entire dentitions occlusion. This index is of use as it divides the arches into segments which would result in a more accurate outcome. This index evaluates tooth relationships from a morphological perspective which has been of use when evaluating the results of orthodontic treatment, post-treatment stability, settling, relapse and different orthodontic treatment modalities. The ITRI can allow for comparisons to be made in an objective and quantitative manner that allows for statistical analysis of orthodontic outcomes.

The efficacy of flow diverters can be evaluated using a grading system developed by researchers at Oxford Neurovascular and Neuroradiology Research Unit (Kamran et al. 2011), commonly referred to as flow diverter grading system or Kamran grading system. After receiving a cerebral flow diverter, patients are placed on dual antiplatelet therapy for an extended period of time to reduce the likelihood of peri-procedural and post-procedural thromboembolic complications. The degree of aneurysm occlusion is graded on a five-point scale from 0 (no change in the endoaneurysmal flow) to 4 (complete obliteration of the aneurysm).

A papillary fibroelastoma is generally considered pathologically benign, however outflow obstruction or embolism can be associated with syncope, chest pain, heart attack, stroke and sudden cardiac death. Symptoms due to papillary fibroelastomas are generally due to either mechanical effects of the tumor or due to embolization of a portion of the tumor to a distal organ. In particular, chest pain or syncope may be due to transient occlusion of the left main coronary artery by the tumor, while a heart attack or sudden cardiac death may be due to embolization of a portion of the tumor into a coronary artery.

George B. Snow is credited as the inventor of face-bow. In his version of face-bow, he positioned the plaster cast in the articulator in respect to distance of median incisal point from the condyles and all the other points on the occlusal plane. Snow attempted to give the occlusal plane an individual position also in this third dimension : and in order to achieve this he set about as follows. He fixed his bite-fork in the upper occlusion rim in such away that the handle, when the rim was placed in the patient's mouth.

Vision-independent adjustment of unit tuning to sound localization cues in response to monaural occlusion in developing owl optic tectum. The Journal of neuroscience: the official journal of the Society for Neuroscience. 12. 3485-93. 10.1523/JNEUROSCI.12-09-03485.1992 Dr. Eric Knudsen performed many different experiments on barn owls over the course of several years to study how vision plays a role in their ability to localize sounds. His studies focused on how visual cues help in mapping parts of the forebrain and midbrain, and also tested if vision impairment has an effect on sound localization in juvenile owls.

Vision- independent adjustment of unit tuning to sound localization cues in response to monaural occlusion in developing owl optic tectum. The Journal of neuroscience: the official journal of the Society for Neuroscience. 12. 3485-93. 10.1523/JNEUROSCI.12-09-03485.1992 As for the effect on the brain, Knudsen was able to conclude that if the owl’s optic tectum was inactivated, then the owl’s brain would have changes in the auditory orienting behavior. As the optic tectum is involved in orienting attention, this explains why some of the owls utilized in his study would elicit a response while others would not.

Weaker topical steroids are utilized for thin-skinned and sensitive areas, especially areas under occlusion, such as the armpit, groin, buttock crease, and breast folds. Weaker steroids are used on the face, eyelids, diaper area, perianal skin, and intertrigo of the groin or body folds. Moderate steroids are used for atopic dermatitis, nummular eczema, xerotic eczema, lichen sclerosis et atrophicus of the vulva, scabies (after scabiecide) and severe dermatitis. Strong steroids are used for psoriasis, lichen planus, discoid lupus, chapped feet, lichen simplex chronicus, severe poison ivy exposure, alopecia areata, nummular eczema, and severe atopic dermatitis in adults.

Posterior cord syndrome (PCS), also known as posterior spinal artery syndrome (PSA), is a type of incomplete spinal cord injury. PCS is the least commonly occurring of the six clinical spinal cord injury syndromes, with an incidence rate of less than 1%. PCS originates from an infarct in the posterior spinal artery and is caused by lesions on the posterior portion of the spinal cord, specifically the posterior column, posterior horn, and posterolateral region of the lateral column. These lesions can be caused by trauma to the neck, occlusion of the spinal artery, tumors, disc compression, vitamin B12 deficiency, syphilis, or multiple sclerosis.

The levels themselves are designed with the same spirit, as corpses, torture victims, and several grotesque situations are witnessed in the game. Collectively, these features caused some public concern about Blood, leading to a censored re-release of the game. In December 2018, Night Dive Studios announced that Atari commissioned them to create an enhanced version of Blood, which was released in May 2019 under the title Blood: Fresh Supply. The new version featured compatibility with modern operating systems and native support for monitor resolutions up to 4K, antialiasing, ambient occlusion and interpolation among other improvements.

Ashton and Richards were brothers-in-law, with Ashton's half-sister, Ina Jane, being married to Richards. Ashton served in the presiding bishopric and as a general authority until his death from coronary occlusion in Salt Lake City.State of Utah Death Certificate Ashton was chairman of the church's General Church Music Committee during his time as a general authority, and he was a frequent contributor to the Improvement Era. Ashton is the father of Marvin J. Ashton, who became a general authority of the church in 1969 and a member of the church's Quorum of the Twelve Apostles in 1971.

Phonak's "Lyric" extended wear hearing aid An extended-wear hearing aid is a type of hearing aid that is placed deep in the ear canal and can be worn for several months at a time without removal. This type of hearing aid is primarily suited for people who have mild to moderately severe hearing loss. This new hearing aid concept was invented by Adnan Shennib, founder of InSound Medical, Inc. The location of these aids directly in the ear canal can provide reduced distortion, wind noise, occlusion and feedback as well as better sound directionality and quality compared to other hearing aids.

Convective precipitation Fronts are the principal cause of significant weather. Convective precipitation (showers, thundershowers, and related unstable weather) is caused by air being lifted and condensing into clouds by the movement of the cold front or cold occlusion under a mass of warmer, moist air. If the temperature differences of the two air masses involved are large and the turbulence is extreme because of wind shear and the presence of a strong jet stream, "roll clouds" and tornadoes may occur. In the warm season, lee troughs, breezes, outflow boundaries and occlusions can lead to convection if enough moisture is available.

The tourniquet consists of an elastic ring made of silicone, stockinet, and pull straps made from ribbon that are used to roll the device onto the limb. The silicone ring tourniquet exsanguinates the blood from the limb while the device is being rolled on, and then occludes the limb once the desired occlusion location is reached. Unlike the historical mechanical tourniquets, the device reduces the risk of nerve paralysis. The surgical tourniquet version of the device is completely sterile, and provides improved surgical accessibility due to its narrow profile that results in a larger surgical field.

Most notably, SOD2 is pivotal in reactive oxygen species (ROS) release during oxidative stress by ischemia-reperfusion injury, specifically in the myocardium as part of a heart attack (also known as ischemic heart disease). Ischemic heart disease, which results from an occlusion of one of the major coronary arteries, is currently still the leading cause of morbidity and mortality in western society. During ischemia reperfusion, ROS release substantially contribute to the cell damage and death via a direct effect on the cell as well as via apoptotic signals. SOD2 is known to have a capacity to limit the detrimental effects of ROS.

The internal diameter of these vessels expands exponentially in the first hours and days following an occlusion, as mitotic division of the cell wall narrows the wall's diameter and expands each vessel's lumen.Within four weeks, the functional capacity of the vessels has reached a maximum, accompanied by a 90% reduction in their resistance, though structural remodeling continues by cell proliferation and synthesis of elastin and collagen over a period of up to six months. Schaper summarizes the status-2009 knowledge of coronary collateral transformation in a recent review:Schaper W. Basic Research in Cardiology. 2009 Jan;104(1):5-21.

The game also features more diversity in Forerunner structures, including fully active Forerunner technology as opposed to the mostly inert and abandoned structures seen in the earlier games. The majority of the game is lit statically using lightmaps; this allowed the art team to achieve realistic lighting effects with full global illumination and ambient occlusion. Image-based lighting is also used to ground scenes and make everything fit together better. The cooperative Spartan Ops mode originally began as a Firefight-type mode, similar to that featured in Halo: Reach, but was composed of different objective-oriented mission types.

Variant angina, and less commonly Prinzmetal angina, vasospastic angina, angina inversa, coronary vessel spasm, or coronary artery vasospasm, is a syndrome typically consisting of angina (cardiac chest pain) in contrast to stable angina which is generally triggered by exertion or intense exercise, commonly occurs in individuals at rest or even asleep and is caused by vasospasm, a narrowing of the coronary arteries due to contraction of the heart's smooth muscle tissue in the vessel walls. In comparison, stable angina is due to the permanent occlusion of these vessels by atherosclerosis (i.e. buildup of fatty plaque and hardening of the arteries).

One strategy to avoid this development is to schedule nitroglycerin-free periods of between 12 and 14 hours between doses of long-acting nitroglycerin formulations. Individuals whose symptoms are poorly controlled by a calcium blocker may benefit from addition of a long- acting nitroglycerin and/or a second calcium channel blocker of a different class than the blocker already in use. Nevertheless, about 20% of individuals fail to respond adequately to the two-drug calcium blocker plus long-acting nitroglycerin regimen. If these individuals have significant permanent occlusion of their coronary arteries, they may benefit by stenting their occluded arteries.

318 career batting average was the highest by any right- handed American League batter since Joe DiMaggio. Puckett was the fourth baseball player during the 20th century to record 1,000 hits in his first five full calendar years in Major League Baseball, and was the second to record 2,000 hits during his first ten full calendar years. After being forced to retire in 1996 at age 36 due to loss of vision in one eye from a central retinal vein occlusion, Puckett was elected to the Baseball Hall of Fame in 2001, his first year of eligibility.

Dogma in vascular bypass technique says to obtain proximal and distal control. This means that in a vessel with flow through it, a surgeon must be have exposure of the furthest and nearest extents of the blood vessel in which the bypass is being created, so that when the vessel is opened, blood loss is minimized. After the necessary exposure, clamps are usually used on both the proximal and distal end of the segment. Exceptions exist where there is no blood flow through the target vessel at the area of proposed entry, as is the case with an intervening occlusion.

A variety of techniques are used to approximate this integral in practice: perhaps the most straightforward way is to use the Monte Carlo method by casting rays from the point \bar p and testing for intersection with other scene geometry (i.e., ray casting). Another approach (more suited to hardware acceleration) is to render the view from \bar p by rasterizing black geometry against a white background and taking the (cosine-weighted) average of rasterized fragments. This approach is an example of a "gathering" or "inside- out" approach, whereas other algorithms (such as depth-map ambient occlusion) employ "scattering" or "outside-in" techniques.

They may either rupture, producing an intracerebral hemorrhage that is initially centered in the region they supply, or they become occluded, producing a lacunar infarct in the tissue they supply. The lenticulostriate arteries are "end arteries", meaning that the regions they supply do not have significant collateral blood supply. Occlusion of these vessels therefore leads to stereotyped stroke syndromes. In the case of the lenticulostriate vessels, hemorrhage may remain localized to the putamen and caudate nucleus, may involve neighboring structures such as the internal capsule and other more distant white matter of the hemisphere, or may even rupture into the ventricular system.

If the fimbriated end of the tube becomes agglutinated, the resulting obstruction does not allow the tubal fluid to pass; it accumulates and reverts its flow downstream, into the uterus, or production is curtailed by damage to the endosalpinx. This tube then is unable to participate in the reproductive process: sperm cannot pass, the egg is not picked up, and fertilization does not take place. Other causes of distal tubal occlusion include adhesion formation from surgery, endometriosis, and cancer of the tube, ovary or other surrounding organs. A hematosalpinx is most commonly associated with an ectopic pregnancy.

Removal of microbial plaque and calculus is necessary to establish periodontal health. The first step in the treatment of periodontitis involves nonsurgical cleaning below the gum line with a procedure called "root surface instrumentation" or "RSI", this causes a mechanical disturbance to the bacterial biofilm below the gumline. This procedure involves the use of specialized curettes to mechanically remove plaque and calculus from below the gumline, and may require multiple visits and local anesthesia to adequately complete. In addition to initial RSI, it may also be necessary to adjust the occlusion (bite) to prevent excessive force on teeth that have reduced bone support.

Angiotension converting enzyme The pathogenesis of renovascular hypertension involves the narrowing of the arteries supplying the kidneys which causes a low perfusion pressure that is detected by the juxtaglomerular apparatus (via the macula densa cells, which act as baroreceptors; located on the afferent arteriole wall). This leads to renin secretion that causes the angiotensinogen conversion to angiotensin I. Angiotensin I then proceeds to the lung where it is converted to angiotensin II via angiotensin converting enzyme (ACE). In most people fibromuscular dysplasia or atherosclerosis is the reason for the occlusion of a renal artery which ultimately leads to this condition.

GCA is considered a medical emergency due to the potential of irreversible vision loss. Corticosteroids, typically high-dose prednisone (1 mg/kg/day), should be started as soon as the diagnosis is suspected (even before the diagnosis is confirmed by biopsy) to prevent irreversible blindness secondary to ophthalmic artery occlusion. Steroids do not prevent the diagnosis from later being confirmed by biopsy, although certain changes in the histology may be observed towards the end of the first week of treatment and are more difficult to identify after a couple of months. The dose of corticosteroids is generally slowly tapered over 12–18 months.

From 2018, a consultant in pre- hospital emergency medicine will be present on most shifts, in addition to the other physician and paramedic. In 2014, London's Air Ambulance performed the first pre-hospital resuscitative endovascular balloon occlusion of the aorta (REBOA). Other key treatments performed by the service include surgical chest draining (thoracostomy), surgical and non-surgical rapid sequence induction (RSI), pelvic splinting (crucial to prevent blood loss in high impact crashes and crush injuries), advanced pain relief and sedation. The service started a trial of a portable brain scanner which can detect blood clots on the brain in April 2015.

Accessed September 19, 2006. A review in 2000 concluded that there were insufficient controlled studies of the approach and a 2008 review concluded that "a large majority of behavioural management approaches are not evidence-based, and thus cannot be advocated." The consensus among Ophthalmologists, Orthoptists and Pediatricians is that "visual training" in non-strabismic Behavioural Vision therapy lacks documented scientific evidence of effectiveness. Although Ophthalmologists and Orthoptists believe that exercises can improve binocular vision control, they believe it does not purely improve monocular visual acuity such as that in amblyopia (rather, occlusion is the therapy of choice), change a person's refractive error.

Often, even a complete occlusion is totally asymptomatic because bilateral circulation keeps the brain well perfused. However, when blood clots form and break off from the site of the tear, they form emboli, which can travel through the arteries to the brain and block the blood supply to the brain, resulting in an ischaemic stroke, otherwise known as a cerebral infarction. Blood clots, or emboli, originating from the dissection are thought to be the cause of infarction in the majority of cases of stroke in the presence of carotid artery dissection. Cerebral infarction causes irreversible damage to the brain.

This caused further public outcry. The Governor ordered a second autopsy; the second pathologist, Dr. Vern Adams, ruled Martin Anderson's death was "caused by suffocation due to actions of the guards at the boot camp. The suffocation was caused by manual occlusion of the mouth, in concert with forced inhalation of ammonia fumes that caused spasm of the vocal cords resulting in internal blockage of the upper airway." Mark A. Ober, State Attorney, Press Release, May 5, 2006 Public indignation resulted in the closing of the state's five juvenile boot camps, the firing of Siebert, and charges of manslaughter against the guards.

Vilevolodon diplomylos was described by Luo et al in 2017 concurrently with another euharamiyid, Maiopatagium furculiferum. Descriptions were carried out based on a skull with preserved teeth in occlusion and a mandibular inner ear, and a fairly complete post-cranial skeleton with carbonized residue of a patagial skin membrane, which has been interpreted as a gliding mechanism. The holotype is represented by a slab and counter-slab with fossil elements preserved across both samples. The holotype was found at the Nanshimen site of the Tiaojishan Formation in Quinglong County, Hebei Province, China, and is currently housed at the Beijing Museum of Natural History.

Dental school is four academic years in duration and is similar in format to medical school: two years of basic medical and dental sciences, followed by two years of clinical training (with continued didactic coursework). Before graduating, every dental student must successfully complete the National Board Dental Examination Part I and II (commonly referred to as NBDE I & II). The NBDE Part I is usually taken at the end of the second year after the majority of the didactic courses have been completed. The NBDE Part I covers Gross Anatomy, biochemistry, physiology, microbiology, pathology, and dental anatomy and occlusion.

Mechanical motion capture systems directly track body joint angles and are often referred to as exoskeleton motion capture systems, due to the way the sensors are attached to the body. A performer attaches the skeletal- like structure to their body and as they move so do the articulated mechanical parts, measuring the performer's relative motion. Mechanical motion capture systems are real-time, relatively low-cost, free-of-occlusion, and wireless (untethered) systems that have unlimited capture volume. Typically, they are rigid structures of jointed, straight metal or plastic rods linked together with potentiometers that articulate at the joints of the body.

Teeth are constantly subject to both horizontal and vertical occlusal forces. With the center of rotation of the tooth acting as a fulcrum, the surface of bone adjacent to the pressured side of the tooth will undergo resorption and disappear, while the surface of bone adjacent to the tensioned side of the tooth will undergo apposition and increase in volume.Trauma from Occlusion Handout, Dr. Michael Deasy, Department of Periodontics, NJDS 2007. page 4 In both primary and secondary occlusal trauma, tooth mobility might develop over time, with it occurring earlier and being more prevalent in secondary occlusal trauma.

On the other hand, unilateral balanced occlusion is a widely used tooth arrangement that is used in current dentistry and is commonly known as group function. This concept is based on the observation that NWS contacts were destructive and therefore the teeth on the NWS should be free of any ececntric contacts, and instead the contacts should be distributed on the WS thus sharing the occlusal load. Group function is used when canine guidance cannot be achieved and also in the Pankey-Mann Schuyler (PMS) approach where it was deemed better than canine guidance as it distributed the loading on the WS better.

Born in Quebec, Canada, Baillargeon is the third child of French-Canadian parents. She is best known for her research showing that infants have an intuitive awareness of physical laws such as solidity, containment, and occlusion at a young age. However, her research interests encompass a variety of issues in causal reasoning, focusing not only on the physical but also the psychological, sociomoral, and biological domains. Baillargeon received a B.A. in Psychology from McGill University in 1975 and a Ph.D. in Psychology from the University of Pennsylvania in 1981 under the supervision of Rochel Gelman and Elizabeth Spelke.

The nasal bones were fused, and there were several short diastemas or gaps in the tooth row at the tip of the snout. More recently, material from the lower jaw, neck and back vertebrae, the upper arm, and armor has been recovered. Hua and Jouve performed a cladistic analysis incorporating their new taxon, and found Argochampsa to be a gavialoid, but outside of the clade Gavialidae. They noted that the snout shape of Argochampsa is unusual among crocodilians, with only pholidosaurids and Terminonaris having similarly shaped snout tips, and suggested that this layout may have facilitated precise occlusion.

When an individual's mouth is at rest, the teeth in the opposing jaws are nearly touching; there is what is referred to as a "freeway space" of roughly 2–3 mm. However, this distance is partially maintained as a result of the teeth limiting any further closure past the point of maximum intercuspidation. When there are no teeth present in the mouth, the natural vertical dimension of occlusion is lost and the mouth has a tendency to overclose. This causes the cheeks to exhibit a "sunken-in" appearance and wrinkle lines to form at the commissures.

Severe acute bleeding, such as caused by ectopic pregnancy and post-partum hemorrhage, leads to hypovolemia (the depletion of blood from the circulation), progressing to shock. This is a medical emergency and requires hospital attendance and intravenous fluids, usually followed by blood transfusion. Once the circulating volume has been restored, investigations are performed to identify the source of bleeding and address it. Uncontrolled life-threatening bleeding may require uterine artery embolization (occlusion of the blood vessels supplying the uterus), laparotomy (surgical opening of the abdomen), occasionally leading to hysterectomy (removal of the uterus) as a last resort.

The task of selecting objects or 3D volumes in a 3D environments requires first being able to find the desired target and then being able to select it. Most 3D datasets/environments are severed by occlusion problems, so the first step of finding the target relies on manipulation of the viewpoint or of the 3D data itself in order to properly identify the object or volume of interest. This initial step is then of course tightly coupled with manipulations in 3D. Once the target is visually identified, users have access to a variety of techniques to select it.

Myocardial infarction is cardiac tissue necrosis that results from occlusion of blood supply via coronary arteries, thereby starving cells of oxygen and nutrients (termed ischemia). Prolong ischemia will eventually kill the cells and the destruction of cardiac cells leads to tissue death, which can lead to heart failure. Delivery of miRNA-210 to an ischemic heart improves heart function, possibly by promoting the release of angiogenic factors like interleukin-1α (IL-1α), tumor necrosis factor-α (TNF-α) and leptin, as seen in HL-1 cardiomyocytes injected with miRNA-210. However, miRNA-210 also targets the Efna3 and Ptp1b genes, which are genes which endogenously regulate angiogenesis and apoptosis, respectively.

On 23 February 2020, the American Society of Retina Specialists reported side effects of the drug, specifically in 14 cases of retinal vasculitis reported in Beovu patients, 11 of the cases were occlusive retinal vasculitis that can lead to vision loss. Novartis responded with a statement standing behind the efficacy of Beovu. On 11 June 2020, the FDA approved an updated Beovu label, that included additional safety information specifically including the characterization of adverse events, retinal vasculitis and retinal vascular occlusion, as part of the spectrum of intraocular inflammation observed in HAWK (NCT02307682) and HARRIER (NCT02434328) clinical trials and noted in the original prescribing information.

Following his travels, Dănăilă was able to perform the most complex of neurosurgical operations, including occlusion of aneurysm of the arterial vertebro-basilar system, ablation of the third ventricle tumors, surgical management of skull base tumors, carotidian and middle cerebral endarterectomy, and extra- and intracranial anastomosis. He also succeeded in reducing operation mortality from operations to percentages comparable with those reported by the world's most reputable neurosurgical clinics. Thus the surgical mortality rate in Bucharest fell from 50% to 2-6% for acoustic nerve neuroma and from 49% to 3% for intracerebral aneurysm cases. These reductions were aided by the endowment of the operating theatre with a surgical microscope and laser.

Exterior view of an architectural model Example of an ambient occlusion layer Achieving accurate computation of global illumination in real- time remains difficult. In real-time 3D graphics, the diffuse inter-reflection component of global illumination is sometimes approximated by an "ambient" term in the lighting equation, which is also called "ambient lighting" or "ambient color" in 3D software packages. Though this method of approximation (also known as a "cheat" because it's not really a global illumination method) is easy to perform computationally, when used alone it does not provide an adequately realistic effect. Ambient lighting is known to "flatten" shadows in 3D scenes, making the overall visual effect more bland.

Botulinum toxin therapy of strabismus is a medical technique used sometimes in the management of strabismus, in which botulinum toxin is injected into selected extraocular muscles in order to reduce the misalignment of the eyes. The injection of the toxin to treat strabismus, reported upon in 1981, is considered to be the first ever use of botulinum toxin for therapeutic purposes. Today, the injection of botulinum toxin into the muscles that surround the eyes is one of the available options in the management of strabismus. Other options for strabismus management are vision therapy and occlusion therapy, corrective glasses (or contact lenses) and prism glasses, and strabismus surgery.

The sense of depth from wiggle 3-D images is due to parallax and to changes to the occlusion of background objects.John Altoft: Data visualization for ESM and ELINT. Visualizing 3-D and hyper-dimensional data, Defense R&D; Canada (DRDC) Ottawa, Contract Report 2011-084, June 2011 Although wiggle stereoscopy permits the perception of stereoscopic images, it is not a "true" three- dimensional stereoscopic display format in the sense that wiggle stereoscopy does not present the eyes with their own separate view each. The apparent stereo effect results from syncing the timing of the wiggle and the amount of parallax to the processing done by the visual cortex.

Acute care of a hemodynamically unstable trauma patient is never an ideal task. The emphasis is on stopping blood extravasation and hemodynamic stabilisation without delay, despite if it is pre-hospital, in the emergency department or in a hybrid operating suite. REBOA, also called Aortic Balloon Occlusion (ABO), is a powerful endovascular tool that inflates an intra-aortic balloon occluding the lumen of the vessel and decreased or completely prevents blood flow to the more distal parts. If inflated in the aorta proximal to the identified source of bleeding it may help to diminish or stop blood extravasation, also potentially aiding to increase cardiac afterload.

Visual input from the macula occupies a substantial portion of the brain's visual capacity. As a result, some forms of visual field loss that occur without involving the macula are termed macular sparing. (For example, visual field testing might demonstrate homonymous hemianopsia with macular sparing.) In the case of occipitoparietal ischemia owing to occlusion of elements of either posterior cerebral artery, patients may display cortical blindness (which, rarely, can involve blindness that the patient denies having, as seen in Anton's Syndrome), yet display sparing of the macula. This selective sparing is due to the collateral circulation offered to macular tracts by the middle cerebral artery.

QuikSCAT image of typical extratropical cyclones over the ocean. Note the maximum winds are on the outside of the occlusion. The windfield of an extratropical cyclone constricts with distance in relation to surface level pressure, with the lowest pressure being found near the center, and the highest winds typically just on the cold/poleward side of warm fronts, occlusions, and cold fronts, where the pressure gradient force is highest. The area poleward and west of the cold and warm fronts connected to extratropical cyclones is known as the cold sector, while the area equatorward and east of its associated cold and warm fronts is known as the warm sector.

The functional face of “short-chain” scorpion toxins is built of two important dyads (Lys and Tyr) on the β-sheet side. Lysine plugs deep into the channel pore and Tyrosine, as penultimate or ultimate and hydrophobic residue, turns it to fixate it, leading to a physical occlusion of the channel pore. This is supported by the finding that deletion of the two C-terminal residues (sBmTx3-delYP) results in loss of ability to block IA-current. The other functional face is thought to be situated at the α-helix-side and composed of Arg18 and Lys19, like the functional face of other hERG toxins.

The ghost ring is a fairly recent innovation, and differs from traditional aperture sights in the extreme thinness of the rear ring and the slightly thicker front sight. The thin ring minimizes the occlusion of the target, while the thicker front post makes it easy to find quickly. Factory Mossberg ghost ring sights also have thick steel plates on either side of the extremely thin ring. These are to protect the sight's integrity in cases where, for example, the shotgun were to fall and impact a surface in a manner that would, in the absence of the steel plates on either side, damage or distort the shape of the ring.

The report also indicated that the news had reached Australia via Arlene Gordon, who had contacted the wife of Gordon's longtime business partner, Detroit-based promoter Arthur Schurgin, who was evidently in Sydney at the time. The cause of Gordon's "mystery" death was reportedly investigated by Scotland Yard but was eventually found to have been a coronary occlusion, although some sources claim that Gordon's friends were skeptical of the official verdict. Lee Gordon was survived by his wife Arlene, and their daughter and son (who was born the following year). Arlene Gordon was reported to have said that her late husband had plans to open clubs in UK.

Cautions to be noted in avoidance of misdiagnoses /contamination of results It is important to avoid prolonged periods of dissociation of the eyes until a diagnosis can be made regarding the strabismus. Hence, the importance to note that although the eyes require dissociation for a minimum of three seconds, that dissociation is kept minimal whilst fixation is maintained. The cover test should be considered prior to testing VA patients with strabismus, for occlusion during testing may dissociate an unstable ocular deviation. In the case of intermittent or latent deviations, for dissociative complications leading to misdiagnosis, it is also advised that binocular vision is tested prior, along with stereo testing.

Diagnosis may be delayed or dismissed as early symptoms may be interpreted as being typical of normal pregnancy. Delays in diagnosis and treatment of PPCM are associated with increased morbidity and mortality. It is also quite common for women to present with evidence of having an embolus (clot) passing from the heart to a vital organ, causing such complications as stroke, loss of circulation to a limb, even coronary artery occlusion (blockage) with typical myocardial infarction (heart attack). For these reasons, it is paramount that clinicians hold a high suspicion of PPCM in any peri- or postpartum patient where unusual or unexplained symptoms or presentations occur.

This can be achieved for example by applying semi-opaque tape or clear nail polish to a large central portion of one side of a pair of spectacles or to a part of both sides. Alternatively, an opaque contact lens that provides a fogging of the central area may offer better cosmesis. Some patients can achieve peripheral fusion when it is merely a central area that is blended out in this manner. (See also binasal occlusion which obscures the nasal part of the field of view for both eyes.) A more drastic measure is the insertion of an opaque intraocular lens to obscure the vision of one eye.

As described below, because of marker occlusion during capturing, tracking fingers is the most challenging part for optical motion capture systems (like Vicon, Optitracks, ART, ..). Users of optical mocap systems claims that the most post-process work is usually due to finger capture. As the inertial mocap systems (if properly calibrated) are mostly without the need for post-process, the typical use for high end mocap users is to fuse data from inertial mocap systems (fingers) with optical mocap systems (body + position in space). The process of fusing mocap data is based on matching time codes of each frame for inertial and optical mocap system data source.

On June 8, 1984, a negatively tilted trough caused an extratropical low pressure area to form over the coast of the Socialist Republic of Romania (now non-Communist Romania). Surface moisture moved north from the Black Sea and caused nearby dew points to rise to ; though at that time these were restricted to Romania and the Ukrainian SSR, dew points were higher than average elsewhere. By 1800 UTC, developing thunderstorms over the Ukrainian SSR spread overnight into the Russian SFSR. Between 00 and 12 UTC on June 9, the strengthening low pressure area moved north-northeast over the northwestern Russian SFSR before undergoing occlusion.

Global aphasia typically results from an occlusion to the trunk of the middle cerebral artery (MCA), which affects a large portion of the perisylvian region of the left cortex. Global aphasia is usually a result of a thrombotic stroke, which occurs when a blood clot forms in the brain's blood vessels. In addition to stroke, global aphasia can also be caused by traumatic brain injury (TBI), tumors, and progressive neurological disorders. The large areas in the anterior (Broca's) and posterior (Wernicke's) area of the brain are either destroyed or impaired because they are separate branches of the MCA that are supplied by its arterial trunk.

Illingworth's research included studies of the medical use of oxygen under pressure. In 1961, he gave the Legg Memorial Lecture at King's College Hospital Medical School on 17 November under the title 'Treatment of Arterial Occlusion under Oxygen at Two-atmospheres Pressure'. The Daryl Hart Lectureship of 1962 was on the same topic: 'Experimental and Clinical Observations Under Hyperbaric Oxygenation' Illingworth's work on hyperbaric oxygenation in the early 1960s would come to be seen as one of the landmarks in the development of hyperbaric oxygen therapy. Illingworth's support of medical training extended beyond the traditional settings of universities and medical schools, and included the use of the medium of television.

When combined into visual routines, these elementary operators can be used to perform relatively sophisticated spatial tasks such as counting the number of objects satisfying a certain property, or recognizing a complex shape. A number of researchers have implemented visual routines for processing camera images, to perform tasks like determining the object a human in the camera image is pointing at. Researchers have also applied the visual routines approach to artificial map representations, for playing real-time 2D video games. In those cases, however, the map of the video game was provided directly, alleviating the need to deal with real-world perceptual tasks like object recognition and occlusion compensation.

After the publication of The Ghost of the Cock in 1964, Webb wrote eight substantial poems (two of which appear in Collected Poems while the rest can be found in the recent selection of his work in the online Australian literary journal Thylazine). In 1967, Webb was praised by Read as "one of the greatest poets of our time . . . one of the most unjustly neglected poets of the century," and Webb has since attracted substantial critical acclaim for his profound vision, his unique spiritual quest to discover the heart of things. Webb died on 23 November 1973 in Sydney's Rydalmere Psychiatric Hospital of a coronary occlusion.

Microphotography of arterial wall with calcified (violet color) atherosclerotic plaque (hematoxylin and eosin stain) Areas of severe narrowing, stenosis, detectable by angiography, and to a lesser extent "stress testing" have long been the focus of human diagnostic techniques for cardiovascular disease, in general. However, these methods focus on detecting only severe narrowing, not the underlying atherosclerosis disease. As demonstrated by human clinical studies, most severe events occur in locations with heavy plaque, yet little or no lumen narrowing present before debilitating events suddenly occur. Plaque rupture can lead to artery lumen occlusion within seconds to minutes, and potential permanent debility and sometimes sudden death.

Carotid stenting is used to reduce the risk of stroke associated with carotid artery stenosis. Carotid stenosis can present with no symptoms or with symptoms such as transient ischemic attacks (TIAs) or strokes. While historically endarterectomy has been the treatment for carotid stenosis, stenting is an alternative intervention for patients who are not candidates for surgery. High risk factors for endarterectomy, which would favor stenting instead, include medical comorbidities (severe heart disease, heart failure, severe lung disease) and anatomic features (contralateral carotid occlusion, radiation therapy to the neck, prior ipsilateral carotid artery surgery, intra-thoracic or intracranial carotid disease) that would make surgery difficult and risky.

As the short gastric veins of the fundus of the stomach drain into the splenic vein, thrombosis of the splenic vein will result in increased pressure and engorgement of the short veins, leading to varices in the fundus of the stomach. Laboratory testing usually shows low red blood cell count and often a low platelet count. If cirrhosis is present, there may be coagulopathy manifested by a prolonged INR; both of these may worsen the bleeding from gastric varices. In very rare cases, gastric varices are caused by splenic vein occlusion as a result of the mass effect of slow-growing pancreatic neuroendocrine tumors.

New associations were formed between the abnormal cue values and the spatial locations they now represented, adjusting the map to translate the cues the bird was receiving into an accurate representation of its environment. This adjustment happens most rapidly and extensively in young birds. However, the map never perfectly reflects abnormal experience, even when cues are altered so early that the bird never experiences normal cues. This indicates that there is some innate “programming” of the map to reflect typical sensory experience.Mogdans, J. and Knudsen, E.I. “Early monaural occlusion alters the neural map of interaural level difference in the inferior colliculus of the barn owl.” Brain Research 619: 29-38, 1993.

A gel containing DMSO, dexpanthenol, and heparin, is sold in Germany and eastern Europe (commercialized under the Dolobene brand) for topical use in sprains, tendinitis, and local inflammation. In interventional radiology, DMSO is used as a solvent for ethylene vinyl alcohol in the Onyx liquid embolic agent, which is used in embolization, the therapeutic occlusion of blood vessels. In medical research, DMSO is often used as a drug vehicle in in vivo and in vitro experiments. However, when a researcher is unaware of its pleiotropic effects, or when the control groups are not carefully planned, a bias can occur; an effect of DMSO can be falsely attributed to the drug.

"Great radicular artery of Adamkiewicz… provides the major blood supply to the lumbar and sacral cord." When damaged or obstructed, it can result in a syndrome of spinal cord ischemia, similar to anterior spinal artery syndrome, with loss of urinary and fecal continence and impaired motor function of the legs; sensory function is often preserved to a degree. It is important to identify the location of the artery when surgically treating an aortic aneurysm to prevent damage which would result in insufficient blood supply to the spinal cord. In bronchial artery embolization for treatment of massive hemoptysis, one of the most serious complications is inadvertent occlusion of the artery of Adamkiewicz.

Stuart explains that the portal they have travelled through has closed, but will reopen on the next Monday, until which time Leopold should stay in Stuart's apartment. As Stuart takes his dog out, he is injured by falling into the empty elevator shaft, and, after ranting about his scientific discovery in the hospital, is involuntarily committed to a mental institution. According to Stuart's concept, Leopold's unintentional time travel to the 21st century has caused a widespread "occlusion" of elevators, and may cause the disappearance of Stuart himself if Leopold doesn't go back on Monday. Leopold is intrigued by the cynical and ambitious Kate McKay, Stuart's ex-girlfriend who lives downstairs.

CJC-1295 was under investigation for the treatment of lipodystrophy and growth hormone deficiency and reached phase II clinical trials but was discontinued upon the death of one of the trial subjects. The attending physician of the trial believed that the most likely explanation for the incident was that the patient had asymptomatic coronary artery disease with plaque rupture and occlusion, and that the occurrence was unrelated to treatment with CJC-1295. In any case, research was terminated nonetheless as a precaution. CJC-1295 has found grey market use for bodybuilding purposes, with this, in some countries such as the Netherlands, being an illicit use.

3D reconstruction and re-projection may be used for stereo conversion. It involves scene 3D model creation, extraction of original image surfaces as textures for 3D objects and, finally, rendering the 3D scene from two virtual cameras to acquire stereo video. The approach works well enough in case of scenes with static rigid objects like urban shots with buildings, interior shots, but has problems with non-rigid bodies and soft fuzzy edges. Another method is to set up both left and right virtual cameras, both offset from the original camera but splitting the offset difference, then painting out occlusion edges of isolated objects and characters.

Patients are instructed to avoid drinking or eating for at least 30 minutes after application. Dental tray can also be fabricated to help in the application of topical steroids to lesional sites under occlusion for patients with gingival involvement. Furthermore, topical tacrolimus, a calcineurin inhibitor, has also shown to be effective to control the disease, including some patients who failed to respond well to topical corticosteroids. Topical tacrolimus 0.1% ointment is applied two to three times a day and tapered after improvement in healing of pemphigoid. Another method is to use intralesional corticosteroids (Triamcinolone acetonide, dilution of 5 to 10 mg/ml; repeated every 2–4 weeks).

Extended wear hearing aids are made of a soft material designed to contour to each user’s ear canal, with a range of canal width sizes to accommodate ear dimensions. An ENT physician, audiologist or hearing aid specialist non-surgically inserts the device into the ear, placing it in the bony portion of the ear canal ~4 mm from the tympanic membrane, or eardrum. The specific placement in the ear canal is said to provide an overall increase in gain and output, greater headroom, reduced occlusion effect, reduced feedback and improved directionality. Once inserted, users can change the volume and settings using a magnetic adjustment tool.

Thus if the central retinal artery gets occluded, there is complete loss of vision in that eye even though the fovea is not affected. The entire retina (with the exception of the fovea) becomes pale and swollen and opaque while the central fovea still appears reddish (this is because the choroid color shows through). This is the basis of the famous "Cherry red spot" seen on examination of the retina on funduscopy of a central retinal artery occlusion (CRAO). However it should be remembered that the Cilio retinal artery itself is a branch of the Short Posterior Ciliary Arteries which is derived from the Ophthalmic Artery.

Bennett later became an orchardist, purchasing a property and living at Glenorie in the Hills district on Sydney's North Western fringe, until 1955 when, due to deteriorating health following a coronary occlusion, he sold his orchard and moved to Dural, New South Wales. He travelled to Singapore in 1957 with his wife to attend the opening of the Kranji War Memorial and then in 1960, travelled to Japan to meet with officers who had fought in Malaya. He wrote a number of articles on military topics and served on the board of a number of companies. From 1960 to 1962, he was Chairman of Directors of MMI Insurance.

Depending upon the location and severity of the occlusion, signs and symptoms may vary within the population affected with PCA syndrome. Blockages of the proximal portion of the vessel produce only minor deficits due to the collateral blood flow from the opposite hemisphere via the posterior communicating artery. In contrast, distal occlusions result in more serious complications. Visual deficits, such as agnosia, prosopagnosia or cortical blindness (with bilateral infarcts) may be a product of ischemic damage to occipital lobe. Occlusions of the branches of the PCA that supply the thalamus can result in central post-stroke pain and lesions to the subthalamic branches can produce “a wide variety of deficits”.

Middle cerebral artery syndrome is a condition whereby the blood supply from the middle cerebral artery (MCA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the lateral aspects of frontal, temporal and parietal lobes, the corona radiata, globus pallidus, caudate and putamen. The MCA is the most common site for the occurrence of ischemic stroke. Depending upon the location and severity of the occlusion, signs and symptoms may vary within the population affected with MCA syndrome. More distal blockages tend to produce milder deficits due to more extensive branching of the artery and less ischemic response.

Standards for Basic Anesthetic Monitoring. Committee of Origin: Standards and Practice Parameters (Approved by the ASA House of Delegates on 21 October 1986, amended 20 October 2010 with an effective date of 1 July 2011) In the UK the Association of Anaesthetists (AAGBI) have set minimum monitoring guidelines for general and regional anesthesia. For minor surgery, this generally includes monitoring of heart rate, oxygen saturation, blood pressure, and inspired and expired concentrations for oxygen, carbon dioxide, and inhalational anesthetic agents. For more invasive surgery, monitoring may also include temperature, urine output, blood pressure, central venous pressure, pulmonary artery pressure and pulmonary artery occlusion pressure, cardiac output, cerebral activity, and neuromuscular function.

Thus, the severity of symptoms correlated inversely with the degree of observed collateral filling. In another often- cited study, Freedman focused on the issue of MI prevention by selecting 121 patients with severe single vessel disease. 64 had Q-wave infarction and 57 did not; 32 had unstable angina or subendocardial infarction. 74 totally occluded vessels and 47 subtotally occluded vessels were identified in this study, and the presence of total occlusion was the most significant predictor of the existence of collaterals. 63 of 74 (85%) of the "totalled" vessels were accompanied by evidence of collaterals, compared to 8 of 47 (17%) of the subtotalled vessels (p=0.001).

Development for Batman started in 2011 at Specular Interactive, who worked with Warner Brothers to build all of the Batmobiles and the Gotham City environment. According to Steve Ranck, the Specular Interactive team spent a lot of time building Gotham City, which in this game "is nearly 10 square miles of various suburbs, unique neighborhoods, elevation changes, tunnels, bridges, hills, dirt roads, jumps, secret paths, etc." Also according to Steve Ranck, the game contains 20 characters "with nearly 1,000 lines of spoken dialog, 3 fully animated boss characters" and 36 missions over 6 stages. Batman uses licensed visibility software, Umbra 3, to handle the occlusion culling in its game.

Surgical treatment of arterial manifestations of BD bears many pitfalls since the obliterative endarteritis of vasa vasorum causes thickening of the medial layer and splitting of elastin fibers. Therefore, anastomotic pseudoaneurysms are likely to form, as well as pseudoaneurysms at the site of the puncture in case of angiography or endovascular treatment; furthermore, early graft occlusion may occur. For these reasons, invasive treatment should not be performed in the acute and active phases of the disease when inflammation is at its peak. The evaluation of disease's activity is usually based on relapsing symptoms, ESR (erythrocyte sedimentation rate), and serum levels of CRP (C‐reactive protein).

For drug-eluting stents (which, by design, delay formation of a new endothelium cover over the stent), the incidence of clot formation within the stent may persist for a longer period of time, perhaps as long as five years after treatment. Drug-eluting stents have been associated with delayed arterial healing and the prevalence of latent thrombus after five years, suggesting patients may continue to be at risk for stent thrombosis for an extended period of time. Though less frequent with drug-eluting stents, neointimal proliferation can still occur in DES and cause restenosis. Stent occlusion because of thrombosis may occur during the procedure, in the following days, or later.

It consists of performing skull radiography under basic conditions which are then "subtracted" to the image after contrast media injection, to provide an image where only brain vessels are displayed, with great improvement in the diagnostic potential. Coils replace balloon occlusion Between the end of the '80s and the beginning of the '90s, INR was suddenly revolutionized after the work of two Italian physicians: Cesare Gianturco and Guido Guglielmi. The first combined a deep knowledge of diagnostic radiology with a great ability to solve technical and manual problems. He invented Gianturco's coils, which he used to make the first attempts to embolize arteries and aneurysms.

Vascular endothelial growth factor (VEGF) is a type of protein the body cells produce to stimulate the growth of new blood vessels. Anti-VEGF agents are chemicals that could inhibit these growth factors to reduce or prevent the abnormal growth of blood vessels, which could lead to damage to the eye and vision. Anti-VEGF drugs are often injected to reduce the swelling or bleeding of the retina, which can be used to treat wet age-related macular degeneration (AMD), macular oedema (which could be diabetic), diabetic retinopathy, retinal vein occlusion, etc. Some common anti-VEGF drugs are bevacizumab (Avastin), ranibizumab (Lucentis) and aflibercept (Eylea/Zaltrap).
