The part of the umbilical arteries closest to the belly button degenerates into ligaments that serve no real purpose but the more internal part becomes part of the circulatory system and is found in the pelvis supplying blood to parts of the bladder, ureters and ductus deferens (a tube sperm moves through in males).
|
|
The ductus must close at birth to allow blood flow into the lungs. In mice, this is accomplished by turning off the mechanism which maintains the ductus's patency. Continuous activation of EP4 by PGE2 keeps the ductus open in the fetus; at birth, however, levels of EP4 and PGE2 in the smooth muscle cells and media in mouse ductus fall. This closes the ductus thereby establishing normal post-fetal circulation of blood through the lungs.
|
|
Based on studies using EP receptor agonists and receptor antagonists, EP2 in mice and, at least in lambs, EP3 may play minor parts in maintaining patency of the ductus. These studies also appear relevant to humans: nonsteroidal anti-inflammatory drugs, particularly indomethacin, are used to reduce prostaglandin production and thereby close the ductus in neonates, infants, and older patients with Patent ductus arteriosus; furthermore, prostaglandins or their analogs are used to keep the ductus open in neonates with congenital heart defects such as Transposition of the great arteries until corrective surgery can be performed (see Ductus arteriosis#Patent Ductus arteriosis). To allow further studies of EP4 function, colonies obtained by cross-breeding the 5% of mice surviving EP4 deletion are used.

While rhythm is tied to tempo, ductus picks up various features of performative language, such as pitch and tone as well. It is for example possible to recognize people by their ductus.
|
|
The cavity of the utricle communicates behind with the semicircular ducts by five orifices. The ductus utriculosaccularis comes off of the anterior wall of the utricle and opens into the ductus endolymphaticus.
|
|
The antrum is strongly sclerotized, with the ductus seminalis attaching slightly before it. The ductus bursae is delicate, with no conspicuous ornaments or structures, as is the bursa copulatrix; a signum is lacking.
|
|
In female genitalia, ovipositor lobes angular. Sterigma present. Ductus bursae broad.
|
|
The ampulla of ductus deferens is an enlargement of the ductus deferens at the fundus of the bladder which acts as a reservoir for sperm. This structure is seen in some mammalian and squamate species and is sometimes tortuous in shape.
|
|
The ductus venosus shows a delayed closure in preterm infants, with no significant correlation to the closure of the ductus arteriosus or the condition of the infant. Possibly, increased levels of dilating prostaglandins leads to a delayed occlusion of the vessel.
|
|
The ductus arteriosus normally closes within one or two days of birth, leaving the ligamentum arteriosum, while the umbilical vein and ductus venosus usually closes within two to five days after birth, leaving, respectively, the liver's ligamentum teres and ligamentum venosus.
|
|
In female genitalia, ovipositor lobes angular. Ductus bursae medium long. Corpus bursae smooth and ovoid.
|
|
Ductus arteriosus closure may be induced by administration of nonsteroidal anti-inflammatory drugs (NSAIDs), which inhibit prostaglandin production. The most common NSAID used is Indomethacin, which is usually administered in the first week after birth. However, in the presence of a congenital defect with impaired lung perfusion (e.g. Pulmonary stenosis and left-to-right shunt through the ductus), it may be advisable to improve oxygenation by maintaining the ductus open with prostaglandin treatment.
|
|
The ductus seminalis attaches at the side, from the hind end of the long, broad ductus bursae, whose surface is mostly roughened. The bursa copulatrix is not sclerotized and very small, with the signum a grainy band that runs around the bursa at midway.
|
|
The species name refers to the ductus seminalis and is derived from Greek paramekes (meaning elongate).

|
In linguistics, ductus is the qualities and characteristics of speaking or writing instantiated in the act of speaking or the flow of writing the text. For instance, in writing, ductus includes the direction, sequencing, and speed with which the strokes making up a character are drawn. Unlike rhythm, ductus is the performative quality that emerges by actuating the metrically arranged language in voice. It is then the specific style and character of the language as it exists within time.
|
|
If the diagnosis is made prenatally, prostaglandin E1 (PGE1) is started after birth to avoid closure of the ductus arteriosus. Prostaglandin therapy is performed via a continuous infusion, due to how quickly prostaglandins are metabolized in the body. However, the diagnosis may go undetected, delaying treatment until closure of the ductus arteriosus produces symptoms. Curative treatment consists of open heart surgery soon after birth, preferably within the first week after birth while there is a patent ductus arteriosus.
|
|
The arteries of the sixth arch persist as the ductus arteriosus on the left, and are obliterated on the right. After birth, the ductus arteriosus regresses to form the ligamentum arteriosum. During growth, these arteries descend into their ultimate positions in the chest, creating the elongated recurrent paths.
|
|
Before the ductus venosus joins the IVC, it is positioned in such a way that the oxygenated blood flowing into the IVC from the ductus venosus preferentially passes on the side of the crista dividens that directs the blood stream toward the left atrium. The rest of the IVC (prior to the joining of the ductus venosus) carries deoxygenated blood from the caudal (inferior) part of the fetus, and is directed toward the side of the crista dividens that directs blood into the right atrium.
|
|
EP4 plays a critical role in postnatal closure of the ductus arteriosus as defined in mice lacking a functional gene for this receptor, i.e. EP4(-/-) mice (see Knockout mouse). About 95% of EP4(-/-) mice die within 3 days of birth due to the pulmonary congestion and heart failure caused by a patent ductus arteriosis. The ductus operates in the fetus to shunt blood from the pulmonary artery to the proximal descending aorta thereby allowing blood from the heart's right ventricle to bypass the fetus's non-functioning lungs.
|
|
The ductus arteriosus is a small, artery-like structure which allows blood to flow from the trunk of the pulmonary artery into the aorta; after birth, the blood in the pulmonary artery will flow into the lungs and the ductus arteriosus will close. Sometimes these shunts will fail to close after birth; these defects are called patent foramen ovale and patent ductus arteriosus, and either may occur independently, or in combination with one another, or with d-TGA or other heart and/or general defects.
|
|
At birth, the ductus arteriosus is still open, and there is higher than normal resistance to blood flow in the lungs. This allows for adequate oxygenation via mixing between the atria and a normal appearance at birth. When the ductus begins to close and pulmonary vascular resistance decreases, blood flow through the ductus is restricted and flow to the lungs is increased. In typical anatomy, the left side of the heart receives oxygen-rich blood from the lungs and pumps it to the rest of the body.
|
|
After it closes, the remnant is known as ligamentum venosum. If the ductus venosus fails to occlude after birth, it remains patent (open), and the individual is said to have a patent ductus venosus and thus an intrahepatic portosystemic shunt (PSS). This condition is hereditary in some dog breeds (e.g. Irish Wolfhound).
|
|
The proximal part of the sixth right arch persists as the proximal part of the right pulmonary artery while the distal section degenerates; The sixth left arch gives off the left pulmonary artery and forms the ductus arteriosus; this duct remains pervious during the whole of fetal life, but then closes within the first few days after birth due to increased O2 concentration. Oxygen concentration causes the production of bradykinin which causes the ductus to constrict occluding all flow. Within 1–3 months, the ductus is obliterated and becomes the ligamentum arteriosum. The ductus arteriosus connects at a junction point that has a low pressure zone (commonly called Bernoulli's principle) created by the inferior curvature (inner radius) of the artery.
|
|
In the female, the ostium is V shaped. The ductus seminalis insert from sideways and above, near the expanded forward end of the ductus bursae. The latter is sclerotized and on the underside has two conspicuous fingered processes. The bursa copulatrix has a fine-grained wall, and the signum is a small sclerotized cone.
|
|
Failure of the ductus arteriosus to close after birth results in a condition called patent ductus arteriosus, which results in the abnormal flow of blood from the aorta to the pulmonary artery: a left-to-right shunt. If left uncorrected, this usually leads to pulmonary hypertension followed by right ventricular heart failure, as well as possible cardiac arrhythmias.
|
|
MedlinePlus Medical Encyclopedia (2007-10-19). Retrieved 2018-08-26. Congenital disorders are acquired before birth. Infants with certain congenital heart defects can survive only as long as the ductus remains open: in such cases the closure of the ductus can be delayed by the administration of prostaglandins to permit sufficient time for the surgical correction of the anomalies.

The periosteum, forming the outer wall of the ductus cochlearis, is greatly thickened and altered in character, and is called the spiral ligament.
|
|
However, such treatments are ineffective in an abnormal ductus. Persistence of the ductus may be associated with other abnormalities, and is much more common in females. By inhibiting PGE2 formation, EP4 receptor activation will decrease and normal circulation can begin. NSAIDs taken late in pregnancy can cross the placenta and lead to premature closure of the DA in the fetus.
|
|
Differential cyanosis is the bluish coloration of the lower but not the upper extremity and the head. This is seen in patients with a patent ductus arteriosus. Patients with a large ductus develop progressive pulmonary vascular disease, and pressure overload of the right ventricle occurs. As soon as pulmonary pressure exceeds aortic pressure, shunt reversal (right-to-left shunt) occurs.

The Mongol script has been the basis of alphabets for several languages. First, after overcoming the Uyghur script ductus, it was used for Mongolian itself.
|
|
PGE1 should be given because a patent ductus arteriosus allows oxygenated blood to go from the circulation of the right heart to the systemic circulation.
|
|
In the female genitalia the appendix bursae has a corresponding three coils to those in the vesica and the ductus bursae is more heavily sclerotized.
|
|
The ductus venosus is open at the time of birth and is the reason why umbilical vein catheterization works. The ductus venosus naturally closes during the first week of life in most full-term neonates; however, it may take much longer to close in pre-term neonates. Functional closure occurs within minutes of birth. Structural closure in term babies occurs within 3 to 7 days.

3D Medical Illustration showing vas deferens. The vas deferens (Latin: "carrying-away vessel"; plural: vasa deferentia), also called ductus deferens (Latin: "carrying-away duct"; plural: ductus deferentes), is part of the male reproductive system of many vertebrates; these ducts transport sperm from the epididymis to the ejaculatory ducts in anticipation of ejaculation. It is a partially coiled tube which exits the abdominal cavity through the inguinal canal.
|
|
The posterior phallus is simple and unmodified or with sclerotized appendages. In the female genitalia, the ductus bursae is normally unsclerotized – a synapomorphy of Lineodini. However, in Leucinodes and Neoleucinodes the posterior ductus bursae, the colliculum and the antrum are often partially sclerotized often have a thickened mesocuticle. The corpus bursae is membranous, but at least Rhectosemia antofagastalis and R. striata exhibit a small sclerotized signum.

She lets House hold Rachel, who throws up on House's shirt. Suddenly, House realizes what is wrong with Sarah: a patent ductus arteriosus (PDA). The ductus arteriosus allows blood to bypass the lungs while developing (since there is no air and the lungs are filled with fluid). When the infant is born, it normally closes, but Sarah's opens during periods of stress, draining deoxygenated blood into her aorta.
|
|
The pathway of fetal umbilical venous flow is umbilical vein to left portal vein to ductus venosus to inferior vena cava and eventually the right atrium. This anatomic course is important in the assessment of neonatal umbilical venous catheterization, as failure to cannulate through the ductus venosus results in malpositioned hepatic catheterization via the left or right portal veins. Complications of such positioning can include hepatic hematoma or abscess.
|
|
Alprostadil is also used in maintaining a patent ductus arteriosus in newborns. This is primarily useful when the threat of premature closure of the ductus arteriosus exists in an infant with ductal- dependent congenital heart disease, including cyanotic lesions (e.g., hypoplastic left heart syndrome, pulmonary atresia/stenosis, tricuspid atresia/stenosis, transposition of the great arteries) and acyanotic lesions (e.g., coarctation of the aorta, critical aortic stenosis, and interrupted aortic arch).

In the fetus, the ductus venosus (Arantius' duct after Julius Caesar Aranzi) shunts a portion of umbilical vein blood flow directly to the inferior vena cava. Thus, it allows oxygenated blood from the placenta to bypass the liver. Compared to the 50% shunting of umbilical blood through the ductus venosus found in animal experiments, the degree of shunting in the human fetus under physiological conditions is considerably less, 30% at 20 weeks, which decreases to 18% at 32 weeks, suggesting a higher priority of the fetal liver than previously realized. In conjunction with the other fetal shunts, the foramen ovale and ductus arteriosus, it plays a critical role in preferentially shunting oxygenated blood to the fetal brain.
|
|
Patent ductus arteriosus (PDA) is a medical condition in which the ductus arteriosus fails to close after birth: this allows a portion of oxygenated blood from the left heart to flow back to the lungs by flowing from the aorta, which has a higher pressure, to the pulmonary artery. Symptoms are uncommon at birth and shortly thereafter, but later in the first year of life there is often the onset of an increased work of breathing and failure to gain weight at a normal rate. With time, an uncorrected PDA usually leads to pulmonary hypertension followed by right-sided heart failure. The ductus arteriosus is a fetal blood vessel that normally closes soon after birth.
|
|
Conversely, in cases of patent ductus arteriosus, where the ductus does not properly close, drugs that inhibit prostaglandin synthesis can be used to encourage its closure, so that surgery can be avoided. Other heart birth defects include ventricular septal defect, pulmonary atresia, and tetralogy of Fallot. An abdominal pregnancy can result in the death of the fetus and where this is rarely not resolved it can lead to its formation into a lithopedion.
|
|
In the fetal heart, the foramen ovale (), also foramen Botalli, or the ostium secundum of Born, allows blood to enter the left atrium from the right atrium. It is one of two fetal cardiac shunts, the other being the ductus arteriosus (which allows blood that still escapes to the right ventricle to bypass the pulmonary circulation). Another similar adaptation in the fetus is the ductus venosus. In most individuals, the foramen ovale closes at birth.

The front part of the anellus is cup shaped, and the aedeagus is long and slim, with an equally elongated and slender cornutus. In the female genitals, the ostium is narrow and U shaped. The antrum is tubular and sclerotized, with the ductus seminalis attaching at its upperside base. The ductus bursae is sclerotized in the forward part, with the hind part being a delicate membrane, and forms a broad loop at its junction with the bursa copulatrix.

Fraser's surgical career encompassed paediatric, abdominal, cardiothoracic and breast surgery and he wrote extensively on all of these. At a time when surgery on the heart was unthinkable, Fraser kept his interest in its possibility. On 19 October 1940 he became the first surgeon in the British Isles to successfully ligate an uninfected patent ductus arteriosus, two weeks after Oswald Tubbs had successfully ligated an infected ductus in London. Robert Gross had performed the first in Boston in 1938.
|
|
However, it is accepted that NSAIDs prevent closure of the fetal ductus arteriosus, which happens during the later stages of pregnancy. Because of this, ibuprofen should be avoided after 30 weeks gestation.

The ductus reuniens also the canalis reuniens of Hensen is part of the human inner ear. It connects the lower part of the saccule to the cochlear duct near its vestibular extremity.
|
|
The second is the ductus arteriosus which shunts blood from the pulmonary artery (which, after birth, carries blood from the right side of the heart to the lungs) to the descending aorta.
|
|
This is so called because it is a narrowing (isthmus) of the aorta as a result of decreased blood flow when in foetal life. As the left ventricle of the heart increases in size throughout life, the narrowing eventually dilates to become a normal size. If this does not occur, this can result in coarctation of the aorta. The ductus arteriosus connects to the final section of the arch in foetal life and the ligamentum arteriosum when the ductus arteriosus regresses.

Freudenthal is known for his Nit Occlud device for treatment of an infant heart problem. The prototypes were first tested on sheep, and since then have been used successfully by Freudenthal on hundreds of children, and have been exported around the world. The device treats a congenital disorder in the heart known as a patent ductus arteriosus (PDA). This occurs when the ductus arteriosus blood vessel, which bypasses the lungs before a baby is born, fails to close up soon after birth.

|
Cyanosis is caused when insufficient oxygenated blood is circulating around the body; in infants it can be known as "blue baby syndrome". Taussig is most remembered for her role in the development of a surgical treatment for this condition, the Blalock-Thomas-Taussig shunt. A new surgery first performed in 1939 by Robert Gross corrected a common pediatric heart problem: patent ductus arteriosus. The ductus arteriosus is a small blood vessel connecting the pulmonary artery to the aorta of a foetus.

Carruthers summarizes: :Intention is primarily a matter of movement, and the initial artisan's intentions (as a set of chosen movements) are conveyed within his artifact through its planned ductus. One experiencing the work does so through and among the various elements of its ductus, namely its formal and stylistic choices or intentiones. That experience is led (ductus) in the first instance not by moral ideas but by pleasure and delight, the desires (which Augustine called intentiones) of the perceiver responding to the "intentions" (movements) of the style imparted to it by the "intentions" (choices) of the artist. To employ Carruthers' insights, an affective meditation, prayer, or piece of art is intended by the author, artist, or compositor to persuade those who read, hear, or behold it by means of the "formal and stylistic choices" he or she makes.
|
|
In some types of congenital heart defect (e.g., transposition of the great arteries), prostaglandins may be administered to maintain the ductus arteriosus open, allowing for the continual circulation and oxygenation of blood, until surgery can be performed.
|
|
With the child's first breath, the lung sends oxygenated blood to the left atrium. As a result, pressure in the left atrium is higher than that of the right, and the increased pressure holds the interatrial flap (which covers the foramen ovale) shut, therefore closing the foramen ovale as well. In normal development, the closed foramen ovale fuses with the interatrial wall. During the first breath, vasoconstriction causes the ductus arteriosus to close, and during adult years, tissue occludes what once was the ductus arterious, creating the ligamentum arteriosum.

Female genitalia with a cup-shaped, weakly sclerotised antrum. In its posterior part, the ductus bursae is sclerotised and longitudinally ridged, the anterior part is membranous and gradually widens towards the globular corpus bursae, which contains a minute spine-like signum near the conjunction with the ductus bursae. Based on material collected on Fernandina Island, the known flying period is between January and May, as well as in August, October, and November. The species inhabits various pristine or anthropized habitats ranging from the littoral zone up to 1341 m elevation.

"The Concept of Ductus". p. 199. Added: Citation and alternate reading of animos A ductus would, hopefully, move people, intellectually and emotionally, through the places of a text to its end, or its intention (intentio) to persuade them one way or another. In The Experience of Beauty in the Middle Ages, Carruthers deepens the analysis of intentio that was also part of the other two books, and lays out three ways that the term is used. These are the interrelated intentiones of the writer/speaker, of the text/speech, and of the reader/auditor.

Covering the surface of the otolithic membrane are otoliths, which are crystals of calcium carbonate. For this reason, the saccule is sometimes called an "otolithic organ." From the posterior wall of the saccule is given off a canal, the ductus endolymphaticus (endolymphatic duct). This duct is joined by the ductus utriculosaccularis, and then passes along the aquæductus vestibuli and ends in a blind pouch saccus endolymphaticus (endolymphatic sac) on the posterior surface of the petrous portion of the temporal bone, where it is in contact with the dura mater.

|
The tribe is circumscribed by three synapomorphies: In the male genitalia, the depth of the central vertical split of the juxta is 10-60% of the juxta length. In the female genitalia, the colliculum, i.e. the posteriormost section of the ductus bursae, situated between the antrum and the attachment of the ductus seminalis, is strongly sclerotised. Furthermore, the corpus bursae usually bears an elongate rhombical, an ovate or an "ediacaroid" signum, named after the Ediacaran biota from the Neoproterozoic Era, which exhibit body shapes similar to the shape of the signum in Udeini.
|
|
Its structure is similar to that of the ductus deferens. Occasionally it is found unconnected with the epididymis. A second tube, the ductulus aberrans superior, occurs in the head of the epididymis; it is connected with the rete testis.
|

In the ear, the extremities of the ductus cochlearis are closed; the upper is termed the lagena and is attached to the cupula at the upper part of the helicotrema; the lower is lodged in the recessus cochlearis of the vestibule.
|
|
The "E" series of prostaglandins are responsible for maintaining the openness of the ductus arteriosus (by dilation of vascular smooth muscle) throughout the fetal period. Prostaglandin E2 (PGE2), produced by both the placenta and the DA itself, is the most potent of the E prostaglandins, but prostaglandin E1 (PGE1) also has a role in keeping the DA open. PGE1 and PGE2 keep the ductus arteriosus open via involvement of specific PGE-sensitive receptors (such as EP4 and EP2). EP4 is the major receptor associated with PGE2-induced dilation of the DA and can be found across the DA in smooth muscle cells.
|
|
Congenital PSS is caused by the failure of the fetal circulatory system of the liver to change. Normally, the blood from the placenta bypasses the liver and goes into circulation via the ductus venosus, a blood vessel found in the fetus. A failure of the ductus venosus to close causes an intrahepatic shunt, while extrahepatic shunts are usually a developmental abnormality of the vitelline veins, which connect the portal vein to the caudal vena cava. Thus in the juvenile and adult animal with PSS, blood from the intestines only partly goes through the liver, and the rest mixes into general circulation.
|
|
Failure to treat the condition yields a mortality rate of 90% at a median age of 4 days. Death occurs due to increased blood flow from the left side of the heart (oxygenated blood) to the right side (deoxygenated blood), inducing heart failure; pulmonary edema; and eventual closing of the ductus arteriosus. For an infant with an interrupted aortic arch, a patent (open) ductus arteriosus allows for blood to bypass the "interruption," without which blood will be unable to reach the lower half of the body. As a result, the kidneys fail and the blood becomes acidic, resulting in death.
|
|
Awaiting surgery, prostaglandin can be administered to keep the ductus arteriosus open, thereby allowing blood flow to the lower body. After successful treatment, the patient is monitored for the rest of their life by a specialist to ensure that problems do not occur.
|
|
While PGE1 is the standard of care for maintaining the ductus arteriosus, there is insufficient data on the proper dose, duration of therapy, safety, and long-term consequences of PGE1 on infants with ductal- dependent congenital heart defects (like interrupted aortic arch).

The ligamentum arteriosum () is a small ligament that is the remnant of the ductus arteriosus formed within three weeks after birth. At the superior end, the ligamentum attaches to the aorta—at the final part of the aortic arch (the isthmus of aorta) or the first part of the descending aorta. On the other, inferior end, the ligamentum is attached to the top of the left pulmonary artery. The ligament is a vestige of the ductus arteriosus, a temporary fetal structure that shunts blood from the pulmonary arteries to the aorta, in order to avoid circulating blood through the lungs, which are inactive in the womb.

|
The crista dividens plays a role in separating oxygenated blood from the ductus venosus and deoxygenated blood from the inferior vena cava (IVC) draining the caudal portion of the fetus into the left and right atria, respectively. The crista dividens is located on the inferior edge of the interatrial septum and faces the opening of the IVC. As blood enters the heart from the IVC, it hits the crista dividens and is divided into two streams, with one stream entering the right atrium and the other entering the left atrium. The ductus venosus joins the terminal portion of the IVC, just before the right atrium.

The study of the ductus (writing style), conducted by comparing the tablets with other inscriptions from the area of Central Italy, has allowed scholars to conclude that they date from no later than the end of the 3rd century for T. III and IV to the first half of the 1st century for the latest T. VI and VII.Adriano Maggiani in Aldo L. Prosdocimi Le Tavole Iguvine Firenze 1984. This may though be considered only a terminus post quem since a style of ductus may last in peripheral areas well after its inception and even well after its demise in culturally dominant areas has occurred. Prosdocimi above p. 153.

In the fetus, there is a special connection between the pulmonary artery and the aorta, called the ductus arteriosus, which directs most of this blood away from the lungs (which are not being used for respiration at this point as the fetus is suspended in amniotic fluid).

The paired mesonephric ducts in the male, in contrast, go on to form the paired epididymis, ductus deferens, ejaculatory duct and seminal vesicle. In the female they may persist between the layer of the broad ligament of the uterus and in the wall of the vagina.

Hermann Treschow Gartner (born October 1785, on the island of Saint Thomas; died April 4, 1827, Copenhagen), was a Danish surgeon and anatomist. His name is associated with the discovery and description of the ductus epoophori longitudinalis (1822). The duct that now bears his name — Gartner's duct.

'" "Our senses produce 'affects' in us," she writes, "physical changes such as emotions, and one of those 'affects' is memory itself....Our memories store 'likenesses' of things as they were when they appeared to and affected us. This analysis...requires that all memory-images have an emotional component, acquired during the process of their formation." The Craft of Thought, focused in on the use (or "craft") of meditative images, and in this book Carruthers added to the mix the concept of ductus, defined in a later essay as "the way (s) that a composition, realizing the plan(s) set within its arrangements, guides a person to its various goals, both in its parts and overall." While on one hand ductus applied to the direction and goal of a whole work, there were places or stages along the way (like the places and images that organized the memory of a speech or a complex idea); and "What marks out the variation in route(s) of the overall ductus are figures, modes and colors of the journey.

Aceclofenac should not be given to people with porphyria or breast-feeding mothers, and is not recommended for children. It should be avoided near term in a pregnant woman because of the risk of having a premature closure of ductus arteriosus leading to fetal hydrops in the neonate.

Spermatozoa has been observed in preovulatory females. Juvenile males have soft, small claspers and undeveloped testes with straight, thread-like ampullae ductus deferens. Adolescents' testes have increased weight and claspers are extended and calcified, but are still flexible. Adults have fully formed and calcified claspers and large and developed testes.

Ibuprofen is a medication in the nonsteroidal anti-inflammatory drug (NSAID) class that is used for treating pain, fever, and inflammation. This includes painful menstrual periods, migraines, and rheumatoid arthritis. It may also be used to close a patent ductus arteriosus in a premature baby. It can be used by mouth or intravenously.

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.
|
|
In the male the Wolffian duct persists, and forms for example the epididymis, the ductus deferens, the ejaculatory duct, seminal vesicle and efferent ducts. In the female, on the other hand, the Wolffian bodies and ducts atrophy, leaving behind only remnants in the adult, involving e.g. the development of the suspensory ligament of the ovary.

Both recipients were Commissioners of the SAP. The SED is a gold Maltese cross with rays between the arms. In the centre is depicted a stylised aloe plant on a blue-bordered white disc on a gold diamond-shaped plaque. The reverse has the national coat of arms and the words "Stella Excellentis Ductus".

Hepatic stellate cells are derived from mesenchyme. After migration of hepatoblasts into the septum transversum mesenchyme, the hepatic architecture begins to be established, with liver sinusoids and bile canaliculi appearing. The liver bud separates into the lobes. The left umbilical vein becomes the ductus venosus and the right vitelline vein becomes the portal vein.

Moreover, he helped the institute translating a relative book despite he was quite weak. When Huang was in the US, the collapse therapy for pulmonary tuberculosis interested him. He plunged into treating the pulmonary tuberculosis patients when he went back Shanghai. Huang focused on the patent ductus arteriosus and cardiopulmonary bypass in the 1960s.

Rockville, MD : Kabel, 2002Johnson SL (1970). History of Cardiac Surgery, 1896-1955. Baltimore: Johns Hopkins Press. p. 5. Surgery in great vessels (aortic coarctation repair, Blalock-Taussig shunt creation, closure of patent ductus arteriosus) became common after the turn of the century and falls in the domain of cardiac surgery, but technically cannot be considered heart surgery.
|
|
Coarctation of the aorta (CoA or CoAo), also called aortic narrowing, is a congenital condition whereby the aorta is narrow, usually in the area where the ductus arteriosus (ligamentum arteriosum after regression) inserts. The word coarctation means "pressing or drawing together; narrowing". Coarctations are most common in the aortic arch. The arch may be small in babies with coarctations.

|
NSAIDs are not recommended during pregnancy, particularly during the third trimester. While NSAIDs as a class are not direct teratogens, they may cause premature closure of the fetal ductus arteriosus and kidney ADRs in the fetus. Additionally, they are linked with premature birth and miscarriage. Aspirin, however, is used together with heparin in pregnant women with antiphospholipid syndrome.

Azygophleps is distinguished from similar genera such as Sansara Yakovlev, 2004, Strigocossus Houlbert, 1916 and Aethalopteryx Schoorl, 1990 by its females’ apically bipectinate antennae, its long forewings rounded at the apex, the absence of arms in its males’ gnathos, its thick aedeagus, and a short, wide ductus and corpus with a small star-like signum in its females.

Since the foetus obtains oxygen via the mother's placenta and not via its own lungs, which are fluid-filled and not yet functional, this vessel provides a shortcut, bypassing the lungs and allowing more efficient delivery of oxygenated blood around the foetus' body. In most infants, the ductus arteriosus closes within a few weeks of birth so that blood flows to the lungs to be oxygenated; if it remains open or 'patent', the normal flow of blood is disrupted. This new surgical procedure artificially closed the blood vessel. While this was going on, Taussig observed that infants with cyanotic heart defects such as Tetralogy of Fallot or pulmonary atresia often fared remarkably better if they also had a patent ductus arteriosus, with less severe symptoms and longer survival.
|
|
Some babies born with cyanotic heart disease are treated with prostaglandin E1 after birth to keep the ductus arteriosus open and allow for more oxygenated blood to be pumped to the body. Many also receive oxygen therapy to increase the percentage of oxygen in the blood. Most of these babies will require surgery during infancy to correct their structural heart defect.

The left venous angle receives lymph from the thoracic duct (Latin: ductus thoracicus). The right venous angle receives lymph from the right lymphatic trunk (Latin: truncus lymphaticus). Truncus lymphaticus is only about 1 cm long and conveys lymph from the right side of the thorax (including parts of the liver) as well as the right arm and parts of the head and neck.
|
|
The epoöphoron lies in the mesosalpinx between the ovary and the uterine tube, and consists of a few short tubules, the ductuli transversi which converge toward the ovary while their opposite ends open into a rudimentary duct, the ductus longitudinalis epoöphori (duct of Gärtner). The ductuli transversi of the epoophoron is a remnant of the tubules of the Wolffian body or mesonephros.

The affective meditation, prayer, or piece of art transmits the intentions inscribed within it— in a way it has these intentions. The perceiver's intentiones (his or her set of desires shaped by individual memory and social/psychological disposition) respond to the design of the ductus, leading to the perceiver's feeling, knowing, and believing what the text, speech, or piece of art intends.

One example is the provocative Kinderzimmertriptychon (Nursery Triptych) from 1971, which is inspired by a picture-book illustration of Fedor Flinzer.See Fedor Bochow: Flinzer, Fedor Alexis, in: Saur Allgemeines Künstlerlexikon. Die Bildenden Künstler aller Zeiten und Völker, Bd. 41, München/Leipzig 2004, 254–256. His work is denoted by a figural-to-symbolic style transition, bright colors and an energetic ductus.
|
|
Patent ductus arteriosus, where blood is channelled back from the heart into the lungs, is also seen and can lead to heart failure. Both of these conditions present with similar symptoms and are inheritable. The OFA conducted a survey on cardiac disease, where of 105 breeds, the King Charles Spaniel was found to be 7th worst, with 2.1% of 189 dogs affected.
|
|
The unpaired umbilical vein carries oxygen and nutrient rich blood derived from fetal-maternal blood exchange at the chorionic villi. More than two-thirds of fetal hepatic circulation is via the main portal vein, while the remainder is shunted from the left portal vein via the ductus venosus to the inferior vena cava, eventually being delivered to the fetal right atrium.
|
|
The ejaculatory ducts (ductus ejaculatorii) are paired structures in male anatomy. Each ejaculatory duct is formed by the union of the vas deferens with the duct of the seminal vesicle. They pass through the prostate, and open into the urethra at the seminal colliculus. During ejaculation, semen passes through the prostate gland, enters the urethra and exits the body via the urinary meatus.
|
|
It carries with it the ductus deference, that is testicular vessels and nerves, a portion of the abdominal muscle, and lymph vessels. All of the structures remain attached to the testis and form what is known as the spermatic cord by the time the testis is in the scrotal sac, the gubernaculum is no more than a remnant of scar like tissue.
|
|
From the lower part of the saccule a short tube, the canalis reuniens of Hensen, passes downward and opens into the ductus cochlearis near its vestibular extremity. Both the utricle and the saccule provide information about acceleration. The difference between them is that the utricle is more sensitive to horizontal acceleration, whereas the saccule is more sensitive to vertical acceleration.
|
|
While there is no treatment to correct the genetic abnormality of this syndrome, there is the potential to treat the symptoms. As a result of infertility, one man from Iran used artificial reproductive methods. An infant in Iran diagnosed with 49,XXXXY syndrome was born with patent ductus arteriosus, which was corrected with surgery, and other complications that were managed with replacement therapy.

|
In TAPVC without obstruction, surgical redirection can be performed within the first month of life. The operation is performed under general anesthesia. The four pulmonary veins are reconnected to the left atrium, and any associated heart defects such as atrial septal defect, ventricular septal defect, patent foramen ovale, and/or patent ductus arteriosus are surgically closed. With obstruction, surgery should be undertaken emergently.
|
|
It also inhibits the effects of the prostaglandin mediated vasodilatation and increased capillary permeability, thereby reducing oedema secondary to capillary leakage. It is also possible that etamsylate would reduce reperfusion haemorrhage in ischaemic areas of the brain, preventing secondary damage. By inhibiting the effects of prostaglandins, etamsylate may exert an effect by closing the patent ductus and thereby increasing cerebral blood flow.
|
|
Surgical interventions can be given to improve functionality and correct cosmetic abnormalities. Osteotomy (bone cutting) and zetaplasty surgeries are used to cut away abnormal tissue growths at the piriform aperture around and pharynx to reduce airway obstruction. Rhinoplasty surgery is used to restore normal appearance and function of the nose. Heart surgery may also be required to close a patent ductus arteriosus.
|
|
Additionally, close monitoring of the ductus arteriosus is done in the neonatal period to ensure that there is adequate blood flow through the pulmonary valve. In certain cases, coronary artery anatomy cannot be clearly viewed using echocardiogram. In this case, cardiac catheterization can be done. Form a genetics perspective, it is important to screen for DiGeorge in all babies with TOF.
|
|
In the sixth week of development the cochlear duct emerges and penetrates the surrounding mesenchyme, travelling in a spiral shape until it forms 2.5 turns by the end of the eighth week. The saccule is the remaining part of the ventral component. It remains connected to the cochlear duct via the narrow ductus reuniens. The dorsal component forms the utricle and semicircular canals.
|
|
Cells in part of the septum primum die creating a hole while muscle cells, the "septum secundum", grow along the right atrial side the septum primum, except for one region, leaving a gap through which blood can pass from the right artium to the left atrium, the foramen ovale. A small vessel, the ductus arteriosus allows blood from the pulmonary artery to pass to the aorta.
|
|
The rate of congenital heart disease in newborns with Down syndrome is around 40%. Of those with heart disease, about 80% have an atrioventricular septal defect or ventricular septal defect with the former being more common. Mitral valve problems become common as people age, even in those without heart problems at birth. Other problems that may occur include tetralogy of Fallot and patent ductus arteriosus.
|
|
A clinical case report showed an association between MonaVie ingestion throughout pregnancy and prenatal closure of the ductus arteriosus resulting in cardiac hypertrophy and dysfunction (pulmonary hypertension) at birth. Another case report noted that MonaVie Active may cause fluctuations in blood clotting (prothrombin time) in patients treated with warfarin or other coumadin blood thinners, and it was recommended that this combination should be avoided.

He created in anti- illusionist and abstract manner, eliminated reminiscences and generalized due to his purely authentic understanding of the realistic. Ilija’s dynamic treatment of the colored structure points to outstandingly modern dimension of his pictorial expression. The backgrounds in his paintings are often empty and flat, while rhythmically sequenced figures are floating, animated with wavy lines. The colour is raw, of visible ductus.
|
|
When the lungs are formed the fetus is held in the fluid-filled amniotic sac and so they do not function to breathe. Blood is also diverted from the lungs through the ductus arteriosus. At birth however, air begins to pass through the lungs, and the diversionary duct closes, so that the lungs can begin to respire. The lungs only fully develop in early childhood.
|
|
The external male sex organs are subject to sexual selection by the female. The male may rub the female's abdomen with its valva during mating. Successful sperm transfer depends upon whether the male spermatophore will fit into the opening of the female ductus seminalis. In a study of sex pheromones, Aglaope infausta was one of the species attracted by tortricids pheromones and caught in the traps.
|
|
With simple d-TGA, if the foramen ovale and ductus arteriosus are allowed to close naturally, the newborn will likely not survive long enough to receive corrective surgery. With complex d-TGA, the infant will fail to thrive and is unlikely to survive longer than a year if corrective surgery is not performed. In most cases, the patient's condition will deteriorate to the point of inoperability if the defect is not corrected in the first year. While the foramen ovale and ductus arteriosus are open after birth, some mixing of red and blue blood occurs allowing a small amount of oxygen to be delivered to the body; if ASD, VSD, PFO, and/or PDA are present, this will allow a higher amount of the red and blue blood to be mixed, therefore delivering more oxygen to the body, but can complicate and lengthen the corrective surgery and/or be symptomatic.
|
|
The aortic arch is the connection between the ascending and descending aorta, and its central part is formed by the left 4th aortic arch during early development. The ductus arteriosus connects to the lower part of the arch in foetal life. This allows blood from the right ventricle to mostly bypass the pulmonary vessels as they develop. The final section of the aortic arch is known as the isthmus of aorta.
|
|
Experimental studies in animals and cohort studies in humans indicate no detectable increase in congenital malformations associated with paracetamol use during pregnancy. Additionally, paracetamol does not affect the closure of the fetal ductus arteriosus as NSAIDs can. Paracetamol use by the mother during pregnancy is associated with an increased risk of childhood asthma. It is also associated with an increase in ADHD but it is unclear whether the relationship is causal.

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.

Partial resection of the hydrocele sac, leaving a margin of 1–2 cm. Care is taken not to injure testicular vessels, epididymis or ductus deferens. The edge of the hydrocele sac is oversewn for hemostasis (von Bergmann's technique) or the edges are sewn together behind the spermatic cord (Winkelmann's or Jaboulay's technique). Hydrocele surgery with excision of the hydrocele sac is useful for large or thick-walled hydroceles and multilocular hydroceles.

Sensory epithelial cells and neurons are derived from the proneurosensory domain. This domain can be further sub-categorized into the neurogenic sub-domain and prosensory sub-domain. Prosensory sub- domain eventually gives rise to the support cells and hair cells while the neurogenic sub-domain gives rise to the auditory neuron and vestibular neuron. The middle part of the otic vesicle develops into the ductus and saccus endolymphaticus.
|
|
The ductus arteriosus stays open because of circulating factors including prostaglandins. The foramen ovale stays open because of the flow of blood from the right atrium to the left atrium. As the lungs expand, blood flows easily through the lungs and the membranous portion of the foramen ovale (the septum primum) flops over the muscular portion (the septum secundum). If the closure is incomplete, the result is a patent foramen ovale.
|
|
In both conditions, the presence of a patent ductus arteriosus (and, when hypoplasia affects the right side of the heart, a patent foramen ovale) is vital to the infant's ability to survive until emergency heart surgery can be performed, since without these pathways blood cannot circulate to the body (or lungs, depending on which side of the heart is defective). Hypoplasia of the heart is generally a cyanotic heart defect.

|
At the hinder part of the medial wall of the vestibule is the orifice of the vestibular aqueduct, which extends to the posterior surface of the petrous portion of the temporal bone. It transmits a small vein, and contains a tubular prolongation of the membranous labyrinth, the ductus endolymphaticus, which ends in a cul-de-sac, the endolymphatic sac, between the layers of the dura mater within the cranial cavity.
|
|
From the posterior wall of the saccule a canal, the endolymphatic duct, is given off; this duct is joined by the ductus utriculosaccularis, and then passes along the aquaeductus vestibuli and ends in a blind pouch (endolymphatic sac) on the posterior surface of the petrous portion of the temporal bone, where it is in contact with the dura mater. Disorders of the endolymphatic duct include Meniere's Disease and Enlarged Vestibular Aqueduct.

He was mentioned in dispatches in 1945. After the second world war he went to Bristol to train in cardiology and in 1948 was appointed registrar at Bristol Royal Infirmary, noted for studies in rheumatic heart disease. From 1951 to 1957 he was lecturer in medicine at Bristol University. During this time he published research on vibration sense, patent ductus arteriosus, paroxysmal nodal tachycardia, and primordial germ cells.

Gartner's duct, also known as Gartner canal and ductus longitudinalis epoophori, is a potential embryological remnant in human female development of the mesonephric duct in the development of the urinary and reproductive organs. It was discovered and described in 1822 by Hermann Treschow Gartner. Gartner's duct is located in the uterus' broad ligament. Its position is parallel with the lateral uterine tube and lateral walls of vagina and cervix.

Promalactis is represented by the combination of the following characters: the smooth head with metallic lustre, the lanceolate forewings with various dark or white markings against yellow to deep ochreous-brown ground colour; the variously shaped symmetrical or asymmetrical valvae and a narrow to very broad sacculus in the male genitalia; and a developed to ill-defined lamella postvaginalis and an elongate thin ductus bursae in the female genitalia.

|
60% to 70% of detected cases, both testes will lie in the normal position for the ovaries; about 20% to 30% of the time, one of the testis will lie within the inguinal hernial sac while in other cases both testes will lie within the same inguinal hernia sac. However whenever an individual exhibits persistent müllerian duct syndrome, the ductus deferens will run along the lateral sides of the uterus.

He was one of the fathers of the field of interventional catheterization, and he developed not only this life-saving technique and device for neonates with transposition of the great arteries, but also devices to close atrial septal defects (ASDs) and persistent patent ductus arteriosus (PDA). He was the chief of the Division of Pediatric Cardiology at the Children's Hospital of Philadelphia until his death in 1986 from malignant melanoma.

The ductus pneumaticus from the gas bladder to the gut in a common rudd. Physostomes are fishes that have a pneumatic duct connecting the gas bladder to the alimentary canal. This allows the gas bladder to be filled or emptied via the mouth. This not only allows the fish to fill their bladder by gulping air, but also to rapidly ascend in the water without the bladder expanding to bursting point.

Holt–Oram syndrome has an autosomal dominant pattern of inheritance. It is unknown if heart-hand syndromes are caused by shared or distinct genetic defects. It has been claimed that congenital heart diseases are caused by a limited number of shared genetic defects. Holt–Oram syndrome, Brachydactyly-long thumb syndrome, Patent ductus arteriosus-bicuspid aortic valve syndrome and Heart-hand syndrome, Slovenian type are known to be autosomally dominant disorders.

The scrotum is an anatomical male reproductive structure located caudal to the penis that consists of a suspended dual-chambered sack of skin and smooth muscle. It is present in most terrestrial male mammals. The scrotum contains the external spermatic fascia, testes, epididymis, and ductus deferens. It is a distention of the perineum and carries some abdominal tissues into its cavity including the testicular artery, testicular vein, and pampiniform plexus.
|
|
Tetralogy of Fallot is a common heart defect experienced in Alagille syndrome patients. Common signs of Alagille syndrome include congenital heart problems varying from heart murmurs to significant structural abnormalities, such as Tetralogy of Fallot. Pulmonary Stenosis, overriding aorta, ventricular septal defect, and right ventricular hypertrophy are common amongst Alagille patients. Patients may also present with Ventricular septal defect, Atrial septal defect, Patent ductus arteriosus, and Coarctation of the aorta.
|
|
Lifespan may be significantly shortened in males with Coffin-Lowry syndrome. Patients may survive into their late twenties, but generally suffer from early mortality due to cardiac, respiratory, and post-operative complications. The progression of reduced cardiac functioning over time may necessitate surgical procedures to counteract mitral valve dysfunction, congenital heart disease, patent ductus arteriosus, and ventricular hypertrophy. Kyphoscoliosis may worsen over time and contribute to these pathologies.

The male genitalia of Niphopyralis are highly derived. The female genitalia exhibit a strongly sclerotised lamella antevaginalis and usually a short, membraneous ductus dursae (strongly sclerotised in Niphopyralis). The signum in the corpus bursae is either absent (Mimetebulea, Niphopyralis) or present as a small to large rounded to short transverse sclerotisation. The larvae and pupae of Wurthiini are only known for Niphopyralis; see there for a morphological description.

In the uterus, the unborn baby is dependent on circulation of blood through the placenta for sustenance including gaseous exchange and the unborn baby's blood bypasses the lungs by flowing through the foramen ovale, which is a hole in the septum dividing the right atrium and left atrium. After birth the umbilical cord is clamped and cut, the baby starts to breathe air, and blood from the right ventricle starts to flow to the lungs for gaseous exchange and oxygenated blood returns to the left atrium, which is pumped into the left ventricle, and then pumped into the main arterial system. As a result of these changes, the blood pressure in the left atrium exceeds the pressure in the right atrium, and this pressure difference forces the foramen ovale to close separating the left and right sides of the heart. The umbilical vein, umbilical arteries, ductus venosus and ductus arteriosus are not needed for life in air and in time these vessels become ligaments (embryonic remnants).

With a similar colouration and wing pattern, the imagines (adult moths) of the A. shanxiensis closely resemble those of A. hortulata, as which they might have been misidentified in the past. Both species can be distinguished from each other by a number of genitalic features, such as the number of coils in the female ductus bursae and the male ductus ejaculatorius (eight coils in A. shanxiensis, seven in A. hortulata), the shape of the sella lobe and of its spinulose process, or the structure of the phallic rods. Genetically, A. shanxiensis and A. hortulata are closely related: In the DNA barcoding fragment of the cytochrome c oxidase subunit I gene, the species exhibit an average of 2.73% of interspecific Kimura two-parameter distance. Using a molecular clock of 0.0115 per site per million years, the divergence time of the sister species A. shanxiensis and A. hortulata is estimated to be 0.9 million years ago.

They are two slender vessels of considerable length, and arise from the front of the aorta a little below the renal arteries. Each passes obliquely downward and lateralward behind the peritoneum, resting on the Psoas major, the right lying in front of the inferior vena cava and behind the middle colic and ileocolic arteries and the terminal part of the ileum, the left behind the left colic and sigmoid arteries and the iliac colon. Each crosses obliquely over the ureter and the lower part of the external iliac artery to reach the abdominal inguinal ring, through which it passes, and accompanies the other constituents of the spermatic cord along the inguinal canal to the scrotum, where it becomes tortuous, and divides into several branches. Two or three of these accompany the ductus deferens, and supply the epididymis, anastomosing with the artery of the ductus deferens; others pierce the back part of the tunica albuginea, and supply the substance of the testis.

|
The risk of major defects or organogenesis is highest for infection in the first trimester. CRS is the main reason a vaccine for rubella was developed. Many mothers who contract rubella within the critical first trimester have either a miscarriage or a stillborn baby. If the fetus survives the infection, it can be born with severe heart disorders (patent ductus arteriosus being the most common), blindness, deafness, or other life- threatening organ disorders.
|
|
The palaeographic analysis of the letterform indicates an early, archaic date. The script used does not clearly match any local variant of the Greek alphabet: certain letter shapes indicate an origin in Attica or Euboea, while other letters point to the ductus common in western Asia Minor, particularly that of Knidos. Overall, the comparison with other early Greek documents suggests a creation of the text in the middle of the 6th century BC.
|
|
Some of the blood from the right atrium does not enter the left atrium, but enters the right ventricle and is pumped into the pulmonary artery. In the fetus, there is a special connection between the pulmonary artery and the aorta, called the ductus arteriosus, which directs most of this blood away from the lungs (which aren't being used for respiration at this point as the fetus is suspended in amniotic fluid).
|
|
They are characterised by their unique female reproductive system which has an external groove between the ostium bursae and the ovipore by which the sperm is transferred to the egg rather than having the mating and egg-laying parts of the abdomen with a common opening (cloaca) as in other nonditrysian moths, or with separate openings linked internally by a "ductus seminalis" as in the Ditrysia. See Kristensen (1999: 57) for other exoporian characteristics.

In terms of hearing, patients are more prone to ear infections, sound blockage, or nerve abnormalities. Several cardiac defects have also been reported, including ventricular/atrial septal defects, atresia, hypoplastic right heart syndrome, patent ductus arteriosus, and conotruncal or valvular cardiac defects. Tetrasomy X patients also appear to be more prone to seizure activity, although there is no documented abnormalities in brain function or structure when analyzed using an EEG or MRI.
|
|
Surgery on the great vessels (e.g., aortic coarctation repair, Blalock–Thomas–Taussig shunt creation, closure of patent ductus arteriosus) became common after the turn of the century. However, operations on the heart valves were unknown until, in 1925, Henry Souttar operated successfully on a young woman with mitral valve stenosis. He made an opening in the appendage of the left atrium and inserted a finger in order to palpate and explore the damaged mitral valve.
|
|
There are only a few differences between the circulatory system of an adult pig and a fetal pig, besides from the umbilical arteries and vein. There is a shunt between the wall of the right and left atrium called the foramen ovale. This allows blood to pass directly from the right to left atrium. There is also the ductus arterius which allows blood from the right atrium to be diverted to the aortic arch.

A relatively healthy breed with no current common health issues, the average life span of a Stabyhoun is 13–15 years. Diet, exercise, care and environment are currently the factors of greatest overall influence on the breed's health and lifespan. The Stabyhoun is an overall a healthy dog. Known congenital health conditions in the breed are Patent Ductus Arteriosis (PDA), Epilepsy, Elbow Dysplasia, Hip Dysplasia and Type 1 von Willebrands Disease (vWB).
|
|
Common defects include atrial septal defect, tetralogy of Fallot, ventricular septal defect, patent ductus arteriosus, pulmonary stenosis, and coarctation of the aorta. Defects of the endocrine system, digestive system, and genitourinary system are also common. These include underdevelopment or agenesis of the pancreas, adrenal glands, thymus, gallbladder, and thyroid; Hirschsprung's disease; gastric reflux, imperforate anus, retention testis, ectopic kidney, renal agenesis, and hydronephrosis. A variety of brain abnormalities are also associated with 13q deletion.
|
|
The male genitalia are characterized by oval to lanceolate valvae with complex sclerotisations of the fibula and sacculus. The uncus exhibits two long, slender, apically tapering or somewhat inflated arms. The phallus or aedeagus is simple, sclerotized and contains a single needle-like cornutus. The female genitalia consist of a simple, sac-like corpus bursae with one or two small signa, a slender ductus bursae with granular texture and a small, sclerotized antrum.
|
|
Closer to the front of the embryo, the vesicles differentiate into a rudimentary saccule, which will eventually become the saccule and cochlea. Part of the saccule will eventually give rise and connect to the cochlear duct. This duct appears approximately during the sixth week and connects to the saccule through the ductus reuniens. As the cochlear duct's mesenchyme begins to differentiate, three cavities are formed: the scala vestibuli, the scala tympani and the scala media.

Infant with cyanosis due to hypoplastic left heart syndrome Closing of the ductus arteriosus in a heart that is severely underdeveloped on the left results in cyanosis and respiratory distress which can progress to cardiogenic shock and death. The first symptoms are cyanosis that does not respond to oxygen administration or poor feeding. Peripheral pulses may be weak and extremities cool to the touch. HLHS often co-occurs with low birth weight and premature birth.
|
|
The ligamentum venosum is the fibrous remnant of the ductus venosus of the fetal circulation. Usually, it is attached to the left branch of the portal vein within the porta hepatis. It may be continuous with the round ligament of liver. It is invested by the peritoneal folds of the lesser omentum within a fissure on the visceral/posterior surface of the liver between the caudate and main parts of the left lobe.
|
|
About 30 to 50 percent of the affected people have other heart abnormalities such as atrial septal defect, patent ductus arteriosus, bicuspid aortic valve, and lung abnormalities. On chest X–ray, the heart looks posteriorly rotated. Another feature is the sharp delineation of pulmonary artery and transverse aorta due to lung deposition between these two structures. If there is partial abscence of pericardium, there will be bulge of the left atrial appendage.

EDRI Federal Project Inventory: Cellular and Molecular Mechanisms of Abnormal Reproductive Development US EPA. Dr. William R. Kelce. 2006. The Wolffian duct forms the epididymis, vas deferens, ductus deferens, ejaculatory duct, and seminal vesicle in the male reproductive system, but essentially disappears in the female reproductive system. The reverse is true for the Müllerian duct, as it essentially disappears in the male reproductive system and forms the Fallopian tubes, uterus, and vagina in the female system.

Other malformations that have been noted with the syndrome are omphalocele and an umbilical hernia. Diagram of a neonatal heart affected by PDA Congenital abnormalities of the heart have also been observed with Malpuech syndrome. From a healthy Japanese couple, Chinen and Naritomi (1995) described the sixth child who had features consistent with the disorder. This two-month-old male infant was also affected by cardiac anomalies including patent ductus arteriosus (PDA) and ventricular septal defect.
|
|
The pathophysiology for this disorder is mostly unknown but there have been a few propositions for its origin. One study suggested that a transient platelet activation of the infant's portal system is responsible for this hyperammonemia. Another study proposed that this occurs due to a shunting of blood away from the portal system of the liver through the ductus venosus directly into the systemic circulation. This causes the blood to skip the step of ammonia removal in the liver.

Blood from the placenta is carried to the fetus by the umbilical vein. In humans, less than a third of this enters the fetal ductus venosus and is carried to the inferior vena cava, while the rest enters the liver proper from the inferior border of the liver. The branch of the umbilical vein that supplies the right lobe of the liver first joins with the portal vein. The blood then moves to the right atrium of the heart.

The wings are brown mottled with white spots and measure about 12 mm across. High individual variation in wing pattern can make the leek moth difficult to distinguish from other Acrolepiopsis species at first, but its distinct genitalia make it easily identifiable. Males of this species can be identified by their long saccus, a portion of the male genitalia used for grasping females, and females by their long and flat ductus bursae, a portion of the female reproductive tract.

Prostaglandin E1 (PGE1), also known as alprostadil, is a naturally occurring prostaglandin which is used as a medication. In babies with congenital heart defects, it is used by slow injection into a vein to open the ductus arteriosus until surgery can be carried out. By injection into the penis or placement in the urethra, it is used to treat erectile dysfunction. Common side effects when given to babies include decreased breathing, fever, and low blood pressure.

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.

Illustration of an aortic coarctation In mild cases, children may show no signs or symptoms at first and their condition may not be diagnosed until later in life. Some children born with coarctation of the aorta have additional heart defects, such as aortic stenosis, ventricular septal defect, patent ductus arteriosus or mitral valve abnormalities. Coarctation is about twice as common in boys as it is in girls. It is common in girls who have Turner syndrome.

Some Azelilini, perhaps all, completely lack the cornuti (spines) on the vesica of the aedeagus usually found in Lepidoptera. Of the female genitalia, the ovipositor is narrow. A robust funnel-shaped antrum - the foremost part of the ostium bursae - is present and the interior of the corpus bursae is studded with small spines, while the ductus bursae is delicate and not sclerotized much. Like the Nacophorini, their caterpillars have many setae on the (vestigial) prolegs of abdominal segment A6.

Spodoptera littoralis is often confused with Spodoptera litura due to similar larvae and adult physical appearances. A bright yellow stripe along the dorsal side of the larvae is characteristic of S. litura. However, due to the variability in markings, the only certain way of distinguishing between the two species is by comparing the genitalia. Specifically, ductus and ostium bursae are known to be the same length in S. littoralis females but different in S. litura females.

The peritoneum of the anterior pelvic wall covers the superior surface of the bladder, and on either side of this viscus forms a depression, termed the paravesical fossa, which is limited laterally by the fold of peritoneum covering the ductus deferens. The size of this fossa is dependent on the state of distension of the bladder; when the bladder is empty, a variable fold of peritoneum, the plica vesicalis transversa, divides the fossa into two portions.

Dr. William Lennox received the Lasker Award in 1951 for his work researching epilepsy. Dr. Lennox organized the American Epilepsy League and the Committee for Public Understanding of Epilepsy. Dr. Robert Gross received the Lasker Award in 1954 for performing the first operation for patent ductus arteriosus, a congenital heart defect, in 1938. He received an additional Lasker in 1959 for being the first surgeon to graft artery tissue from one person to another in 1958.

During his stay in Amsterdam, Steno discovered a previously undescribed structure, the "ductus stenonianus" (the duct of the parotid salivary gland) in sheep, dog and rabbit heads. A dispute with Blasius over credit for the discovery arose, but Steno's name remained associated with this structure known today as the Stensen's duct. In Leiden, Steno studied the boiled heart of a cow, and determined that it was an ordinary muscle and not the center of warmth as Galenus and Descartes believed.Kooijmans (2007), p. 45.

McGillivray syndrome is a rare syndrome characterized mainly by heart defects, skull and facial abnormalities and ambiguous genitalia. The symptoms of this syndrome are ventricular septal defect, patent ductus arteriosus, small jaw, undescended testes, and webbed fingers. Beside to these symptoms there are more symptoms which is related with bone structure and misshape. McGillivray syndrome is a birth defect in which one or more of the joints between the bones of the baby's skull close prematurely, before the baby's brain is fully formed.

The fetus obtains oxygen and nutrients from the mother through the placenta and the umbilical cord. Blood from the placenta is carried to the fetus by the umbilical vein. About half of this enters the fetal ductus venosus and is carried to the inferior vena cava, while the other half enters the liver proper from the inferior border of the liver. The branch of the umbilical vein that supplies the right lobe of the liver first joins with the portal vein.

During development of the heart, the heart tissues undergo folding, and the truncus arteriosus is exposed to what will eventually be both the left and right ventricles. As a septum develops between the two ventricles of the heart, two bulges form on either side of the truncus arteriosus. These progressively enlarge until the trunk splits into the aorta and pulmonary arteries. During early development, the ductus arteriosis connects the pulmonary trunk and the aortic arch, allowing blood to bypass the lungs.

Women in the third trimester of pregnancy should avoid this drug because there is a risk that naproxen, like other NSAIDs, may cause premature closure of the ductus arteriosus. In October 2020, the U.S. Food and Drug Administration (FDA) required the drug label to be updated for all nonsteroidal anti-inflammatory medications to describe the risk of kidney problems in unborn babies that result in low amniotic fluid. They recommend avoiding NSAIDs in pregnant women at 20 weeks or later in pregnancy.

Textual reconstruction of the Plomin tablet. General paleographic analysis shows that the rounded Glagolitic is still used, preceding the development of Croatian angular Glagolitic, which dates the monument before the 12-13th century. An analysis of individual graphemes also points to this timeframe: There's the letter S (1, 6, 10) which still has triangular lower element and the letter I (5) which still has triangular upper element, i.e. which has not reduced the ductus the way it can be observed on Vienna Folios.

The striking aedeagus is shaped like a coiled whip, consisting of a long and tapering "thong" and ending in a shorter and thin "fall" section. The function of this structure during copulation is unknown. However, there are a few moths with similarly elongated whip-like aedeagi, and in these the female's ductus bursae is long and coiled to accommodate the aedeagus. A similar aedeagus is known from South Asian moths of the genus Talanga, which are suspected to be closely related.

The Yasui procedure is done via a median sternotomy and uses cardiopulmonary bypass. If there is a patent ductus arterosus, the surgeon begins by closing it. The surgeon then connects the separated parts of the aorta together. The surgeon then transects the pulmonary artery and aorta and frees them from surrounding tissue, then makes an incision into the right ventricle to allow them to assess the ventricular septal defect and remove excess muscle bundles in cases of extensive right ventricular hypertrophy.

In pregnant women, ACE inhibitors taken during all the trimesters have been reported to cause congenital malformations, stillbirths, and neonatal deaths. Commonly reported fetal abnormalities include hypotension, renal dysplasia, anuria/oliguria, oligohydramnios, intrauterine growth retardation, pulmonary hypoplasia, patent ductus arteriosus, and incomplete ossification of the skull. Overall, about half of newborns exposed to ACE inhibitors are adversely affected, leading to birth defects. ACE inhibitors are ADEC pregnancy category D, and should be avoided in women who are likely to become pregnant.

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.

Multi-system abnormalities are common in ZTTK syndrome. The majority of individuals diagnosed with ZTTK syndrome display congenital malformations such as urogenital and malformations, heart defects, and a high or cleft palate. Congenital defects such as a thinned atrial septum, ventricular septal defects, patent ductus arteriosus, dysplastic kidney and agenesis of the lung and gallbladder have also been noted. Whole body musculoskeletal abnormalities have been observed in ZTTK syndrome patients, including hemivertebrae, scoliosis or kyphosis, contractures, joint laxity, joint hypermobility and hypotonia.

Inhaled nitric oxide is contraindicated in the treatment of neonates known to be dependent on right-to-left shunting of blood. This is as the nitric oxide decreases the pulmonary circulation's resistance by dilating pulmonary blood vessels. The increased pulmonary return increases pressure in the left atrium, causing closure of the foramen ovale and reducing the blood flow through the ductus arteriosus. Closing these shunts can kill neonates with heart malformations that rely on the right-to-left shunting of blood.

During the second day, the baby may be remarkably stable on adequate support and resolution is noted during the third day, heralded by a prompt diuresis. Despite huge advances in care, IRDS remains the most common single cause of death in the first month of life in the developed world. Complications include metabolic disorders (acidosis, low blood sugar), patent ductus arteriosus, low blood pressure, chronic lung changes and bleeding in the brain. The syndrome is frequently complicated by prematurity and its additional effect on other organ functions.

Normal right-sided vasogram showing right ductus deferens (arrowhead), seminal vesicle (SV), and ejaculatory duct (arrow) with retrograde opacification of the urinary bladder (UB). Vasography is an X-ray study of the vas deferens to see if there is blockage, oftentimes in the context of male infertility. An incision is made in the scrotum, contrast is injected in the vas deferens, and X-rays are taken from different angles. Thus, it is an invasive procedure and carries risk of iatrogenic scarring and obstruction of the vas.

The spermatic cord is the cord-like structure in males formed by the vas deferens (ductus deferens) and surrounding tissue that runs from the deep inguinal ring down to each testicle. Its serosal covering, the tunica vaginalis, is an extension of the peritoneum that passes through the transversalis fascia. Each testicle develops in the lower thoracic and upper lumbar region and migrates into the scrotum during its descent it carries along with it vas deferens, its vessels, nerves etc. There is one on each side.

The South African Police Star for Distinguished Leadership was a high-ranking decoration, that existed between 1979 and 1986. It was reserved for senior police officers, and was awarded only twice. Recipients were entitled to use the post-nominal letters SED, standing for Stella Excellentis Ductus, the Latin form of the name. Instituted on 1 May 1979, the SED was awarded to general officers of the South African Police for distinguished leadership, meritorious service contributing to state security, and outstanding service to heads of state or government.

Isolated double aortic arch without associated intracardiac defects is a vascular anomaly that can be corrected without the support of cardiopulmonary bypass. For surgical division of the narrower left aortic arch in a typical double arch patient with a dominant right arch, the patient is placed on the right side. After prepping and draping of the left chest a posterolateral thoracotomy is performed. The chest cavity is entered between the fourth and fifth rib (fourth intercostal space, as in the operation for patent ductus arteriosus or coarctation).

It is evident that 4Q108 is not from the other two manuscripts of the Song found in the cave. The last two words of Song 3:7, g'bore Israel ("warriors of Israel") are already accounted for in 4Q106; and the letters of 4Q107 are formed by an observably different hand to 4Q108. The manner of composition (ductus) of the letters aleph and shin differs between the manuscripts. Additionally, the lacuna in the second column of 4Q107 does not provide enough space to accommodate 4Q108.

This causes symptoms of pressure on the nearby organs. It is associated with several cardiac abnormalities such as patent ductus arteriosus, atrial septal defect, ventricular septal defect, and tetralogy of Fallot. Although CLE may be caused by the abnormal development of bronchi, or compression of airways by nearby tissues, no cause is identified in half of cases. CT scan of the lungs is useful in assessing the anatomy of the lung lobes and status of the neighbouring lobes on whether they are hypoplastic or not.

In 2008, the Federal Trade Commission sued Ovation in Minnesota federal district court over its 2006 acquisition of NeoProfen, a treatment for a congenital heart defect in newborns known as patent ductus arteriosus. Ovation already owned Indocin IV, the only other drug used for this condition. Upon acquiring the only competitor for Indocin IV, Ovation raised the price of both drugs by 1,300 percent, from $36 per vial to nearly $500 per vial. The dramatic price increase was the subject of a 2008 Congressional hearing.

The umbilical cord enters the fetus via the abdomen, at the point which (after separation) will become the umbilicus (or navel). Within the fetus, the umbilical vein continues towards the transverse fissure of the liver, where it splits into two. One of these branches joins with the hepatic portal vein (connecting to its left branch), which carries blood into the liver. The second branch (known as the ductus venosus) bypasses the liver and flows into the inferior vena cava, which carries blood towards the heart.

In some countries, ibuprofen lysine (the lysine salt of ibuprofen, sometimes called "ibuprofen lysinate") is licensed for treatment of the same conditions as ibuprofen; the lysine salt is used because it is more water-soluble. In 2006, ibuprofen lysine was approved in the U.S. by the Food and Drug Administration (FDA) for closure of patent ductus arteriosus in premature infants weighing between , who are no more than 32 weeks' gestational age when usual medical management (such as fluid restriction, diuretics, and respiratory support) is not effective.

Without life-prolonging interventions, HLHS is fatal, but with intervention, an infant may survive. A cardiothoracic surgeon may perform a series of operations or a full heart transplant. While surgical intervention has emerged as the standard of care in the United States, other national health systems, notably in France, approach diagnosis of HLHS in a more conservative manner, with an emphasis on termination of pregnancy or compassionate care after delivery. Before surgery, the ductus must be kept open to allow blood-flow using medication containing prostaglandin.

About one third of children whose mothers are taking this drug during pregnancy typically have intrauterine growth restriction with a small head and develop minor dysmorphic craniofacial features (microcephaly and mental retardation) and limb defects including hypoplastic nails and distal phalanges (birth defects). Heart defects including ventricular septal defect, atrial septal defect, patent ductus arteriosus and coarctation of the aorta may occur in these children. A smaller population will have growth problems and developmental delay, or intellectual disability. Methemoglobinemia is a rarely seen side effect.

Common symptoms include a grayish-blue (cyanosis) coloration to the skin, lips, fingernails and other parts of the body. Other pronounced symptoms can be rapid/difficulty breathing, poor feeding, cold hands or feet, or being inactive and drowsy. "In a baby with hypoplastic left heart syndrome, if the natural connections between the heart's left and right sides (foramen oval and ductus arteriosus) are allowed to close, he or she may go into shock." Signs of shock can include cool or clammy skin, a weak or rapid pulse, and dilated pupils.
|
|
Almost immediately after the infant is born, the foramen ovale and ductus arteriosus close. The major changes that are made by the body occur at the first breath (in the case of heart and lung functions) and up to weeks after birth (such as the liver's enzyme synthesis). The foramen ovale becomes the fossa ovalis as the foramen closes while edge of the septum secundum in right atrium becomes anulus ovalis, so the depression beneath it becomes the fossa ovalis. This enables respiration and circulation independent from the mother's placenta.

An uncorrected left- to-right shunt can progress to a right-to-left shunt; this process is termed Eisenmenger syndrome. This is seen in Ventricular septal defect, Atrial septal defect, and patent ductus arteriosus, and can manifest as late as adult life. This switch in blood flow direction is precipitated by pulmonary hypertension due to increased pulmonary blood flow in a left-to-right shunt. The right ventricle hypertrophies to compensate for this pulmonary hypertension, so the right ventricular pressure becomes higher than the pressure in the left ventricle.

Clenched hand and overlapping fingers: index finger overlaps third finger and fifth finger overlaps fourth finger, characteristically seen in trisomy 18. This is caused by congenital joint contracture. Children born with Edwards syndrome may have some or all of these characteristics: kidney malformations, structural heart defects at birth (i.e., ventricular septal defect, atrial septal defect, patent ductus arteriosus), intestines protruding outside the body (omphalocele), esophageal atresia, intellectual disability, developmental delays, growth deficiency, feeding difficulties, breathing difficulties, and arthrogryposis (a muscle disorder that causes multiple joint contractures at birth).

A drawing of two Sussex Spaniels from 1859 Heart conditions in the Sussex Spaniel can include pulmonary valve stenosis, which is the most common of the congenital heart defects. Essentially, in an animal with this condition, the pulmonary valve is improperly formed which causes the heart to work much faster to pump blood around the body. The final results of this condition can be swelling of fluid in the chambers of the heart, thickening of the heart muscle known as ventricular hypertrophy leading to eventual heart failure. Patent ductus arteriosus also appears in the breed.

Paracetamol is used to treat patent ductus arteriosus, a condition that affects newborns when a blood vessel used in developing the lungs fails to close as it normally does, but evidence for the safety and efficacy of paracetamol for this purpose is lacking. NSAIDs, particularly indomethacin and ibuprofen, have also been used, but the evidence for them is also not strong. The condition appears to be caused in part by overactive prostaglandin E2 (PGE2), signalling primarily through its EP4 receptor, but possibly also through its EP2 receptor and EP3 receptors.

Elsevier, 2009 It has been associated with acute liver damage. In 2008 the US label was updated with a warning concerning a risk of premature closure of the ductus arteriosus in pregnancy.FDA March 2008 FDA advisory In October 2020, the U.S. Food and Drug Administration (FDA) required the drug label to be updated for all nonsteroidal anti-inflammatory medications to describe the risk of kidney problems in unborn babies that result in low amniotic fluid. They recommend avoiding NSAIDs in pregnant women at 20 weeks or later in pregnancy.

A review and meta-analysis showed that paracetamol may be effective for closure of a PDA in preterm infants. A recent network meta-analysis that compared indomethacin, paracetamol and ibuprofen at different doses and administration schemes among them found that a high dose of oral ibuprofen may offer the highest likelihood of closure in preterm infants. While indomethacin can be used to close a PDA, some neonates require their PDA be kept open. Keeping a ductus arteriosus patent is indicated in neonates born with concurrent heart malformations, such as transposition of the great arteries.

The procedure of deferentectomy, also known as a vasectomy, is a method of contraception in which the vasa deferentia are permanently cut, though in some cases it can be reversed. A modern variation, which is also known as a vasectomy even though it does not include cutting the vas, involves injecting an obstructive material into the ductus to block the flow of sperm. Investigational attempts for male contraception have focused on the vas with the use of the intra vas device and reversible inhibition of sperm under guidance.

Another portion of the mesonephritic duct becomes the ductus deferens. The seminal vesicles form from lateral outgrowths of the caudal and of each mesonephritic duct the prostate gland arises from an Indo dermal outgrowth of the urogenital sinus the bulbourethral glands develop from outgrowths in the membrane-like portion of the urethra. The descent of the testes to its final location at the anterior abdominal wall, followed by the development of the gubernaculum, which subsequently pulls and translocates the testis down into the developing scrotum. Ultimately, the passageway closes behind the testis.

Photograph taken c. 1920 shows graffiti from Pompeii with painted Roman square capitals. Most of the graffiti was destroyed during World War II. Studying in Rome as a seminarian in the late 1930s, he made a thorough study of the letter forms of the epigraphy on Trajan's Column. While the brushed-origin thesis had been proposed in the nineteenth century, Catich, having worked as a union sign painter, made a complete study and proposed a convincing ductus by which the forms were created, using a flat brush and then chisel.

Pulmonary valve regurgitation presents as a diastolic decrescendo murmur at the left lower sternal border. A palpable S2 in the second left intercostal space correlates with pulmonary hypertension due to mitral stenosis. Continuous and Combined Systolic/Diastolic Patent ductus arteriosus may present as a continuous murmur radiating to the back. Severe coarctation of the aorta can present with a continuous murmur: a systolic component at the left infraclavicular region and the back due to the stenosis, and a diastolic component over the chest wall due to blood flow through collateral vessels.

In the growing fetus, a major source of blood to the liver is the umbilical vein, which supplies nutrients to the growing fetus. The umbilical vein enters the abdomen at the umbilicus and passes upward along the free margin of the falciform ligament of the liver to the inferior surface of the liver. There, it joins with the left branch of the portal vein. The ductus venosus carries blood from the left portal vein to the left hepatic vein and then to the inferior vena cava, allowing placental blood to bypass the liver.
|
|
In the fetus, the liver does not perform the normal digestive processes and filtration of the infant liver because nutrients are received directly from the mother via the placenta. The fetal liver releases some blood stem cells that migrate to the fetal thymus, creating the T-cells or T-lymphocytes. After birth, the formation of blood stem cells shifts to the red bone marrow. After 2–5 days, the umbilical vein and ductus venosus are completely obliterated; the former becomes the round ligament of liver and the latter becomes the ligamentum venosum.

Considering the fact that a large proportion of mortality cases of pulmonary agenesis are partly due to the presence of associated malformations, it is common to find other congenital anomalies associated with this type of disorder. Although some cases of bilateral pulmonary agenesis were reported as an isolated finding, most cases of pulmonary agenesis are associated with other anomalies, especially in the gastrointestinal, genitourinary and ocular systems. Frequently associated congenital anomalies include tracheal stenosis, esophageal atresia, tracheoesophageal fistula, bronchogenic cysts, patent ductus arteriosus, tetralogy of Fallot and anomalies of the great vessels.

Isodemis is characterized by the labial palpus obliquely uprising almost as high as the upper edge of the eye. The forewing is dominantly yellowish brown or ochreous brown, the median fascia is interrupted or indistinct near the costal margin. The male genitalia have a hooked gnathos and the valva have a C-shaped plica, with numerous fine wrinkles between the plica and costa. The female genitalia usually have a ductus bursae with a cestum and the single dentate signum with a conspicuous globular process placed posteriorly in the corpus bursae.

The National Academies Press called him "one of America's great pioneers of surgery". The New York Times said that he did "pioneering work in the field of cardiac surgery". According to his obituary in The New York Times, in 1938 Gross "performed the first surgical correction of one of the most common congenital heart disorders in children", referring to the ligation of the patent ductus. Ten years later he performed the first surgery to graft artery tissue from one person into another, thus making a leap in methods of repairing of damaged arteries.

April 1994) The exhibition took place in the same year that the couple and their two sons had immigrated to Munich and had received political asylum. In the years between 2001 and 2012, Mahbuba Elham Maqsoodi’s artwork mainly focused on architectural based contractual orders. For her, it meant to professionally adapt the artistic language of the 19th century (Pre-Raphelite and Romanesque style). From 2012, she moved to create a whole cycle of new paintings in her own artistic language, style, and personal ductus, which gained great attention in 2017 with her solo exhibition “GlasKlar” at Munich’s Maximilianeum.

A consistent positive association between consanguinity and disorders such as ventricular septal defect and atrial septal defect has been demonstrated, but both positive and negative associations with patent ductus arteriosus, atrioventricular septal defect, pulmonary atresia, and Tetralogy of Fallot have been reported in different populations. Associations between consanguinity and Alzheimer's disease have been found in certain populations. Studies into the influence of inbreeding on anthropometric measurements at birth and in childhood have failed to reveal any major and consistent pattern, and only marginal declines were shown in the mean scores attained by consanguineous progeny in tests of intellectual capacity.

Beside reducing respiratory distress, other neonatal complications are reduced by the use of glucocorticosteroids, namely intraventricular bleeding, necrotising enterocolitis, and patent ductus arteriosus. A single course of antenatal corticosteroids could be considered routine for preterm delivery, but there are some concerns about applicability of this recommendation to low-resource settings with high rates of infections. It remains unclear whether one corticosteroid (or one particular regimen) has advantages over another. Concerns about adverse effects of prenatal corticosteroids include increased risk for maternal infection, difficulty with diabetic control, and possible long-term effects on neurodevelopmental outcomes for the infants.

On this tower was once a large inscription, now disappeared: aquae Cornealiae ductus p. XX. The last letters ("twenty feet") perhaps corresponds to the sides of the building. Later it seems that the aqueduct passed further downstream: in Figurella a double-order bridge of arches is still visible (originally nine in the lower, fifteen in the upper: two arches for each order collapsed), 14 m high. The structure with facing blocks is the same as that of the amphitheatre and the curia and shows that it belongs to the same building project of the Augustan colony.

The works of Armin Baumgarten arise beyond the antagonism between the figurative and the abstract, i.e. this picture is not borrowed from the optical reality, but establishes itself within a picturesque charging process on the scene as a separate image reality. From the painting originally thin liquid Armin Baumgarten came to a very tactile, impasto ductus gain by the motifs a physical presence. This development process resulted since 2003 in the study of sculpture that is created first in a lengthy process of work up and ablation of gypsum and is then implemented as a bronze casting.

The pulmonary circulation loop is virtually bypassed in fetal circulation. The fetal lungs are collapsed, and blood passes from the right atrium directly into the left atrium through the foramen ovale: an open conduit between the paired atria, or through the ductus arteriosus: a shunt between the pulmonary artery and the aorta. When the lungs expand at birth, the pulmonary pressure drops and blood is drawn from the right atrium into the right ventricle and through the pulmonary circuit. Over the course of several months, the foramen ovale closes, leaving a shallow depression known as the fossa ovalis.

Ross has recalled eagerly accepting the scholarship: once in England he took up a career in surgery and became a Fellow of the Royal College of Surgeons (1949) within two years instead of the usual three. Working initially in Bristol he focused on chest and oesophageal surgery, and then began to include early cardiac surgery, such as on the ductus arteriosus. He was appointed Senior Registrar in Thoracic Surgery, Bristol, in 1952. Ross acknowledges the particular influence on his career of two key figures: Ronald Belsey, MD, and Russell Claude Brock, FRCS, FRCP (later Lord Brock).

The ductus arteriosus becomes the ligamentum arteriosum within three weeks of birth, so that deoxygenated blood can be selectively circulated to the lungs for more efficient oxygenation of the blood. The ligamentum arteriosum is closely related to the left recurrent laryngeal nerve, a branch of the left vagus nerve. After splitting from the left vagus nerve, the left recurrent laryngeal loops around the aortic arch behind the ligamentum arteriosum, after which it ascends to the larynx. This ligament also plays a role in major trauma; it fixes the aorta in place during abrupt motions, consequently potentially resulting in ruptured aorta.

Between 5% and 10% of those born with Turner syndrome have coarctation of the aorta, a congenital narrowing of the descending aorta, usually just distal to the origin of the left subclavian artery (the artery that branches off the arch of the aorta to the left arm) and opposite to the ductus arteriosus (termed "juxtaductal"). Estimates of the prevalence of this malformation in patients with Turner syndrome range from 6.9 to 12.5%. A coarctation of the aorta in a female is suggestive of Turner syndrome and suggests the need for further tests, such as a karyotype.

The syndrome consists of severe micrognathia, cleft lip and/or palate, hypoplasia or aplasia of the postaxial elements of the limbs, coloboma of the eyelids and supernumerary nipples. Additional features of the syndrome include downward- slanting palpebral fissures, malar hypoplasia, malformed ears, and a broad nasal ridge. Other features include supernumerary vertebrae and other vertebral segmentation and rib defects, heart defects (patent ductus arteriosus, ventricular septal defect and ostium primum atrial septal defect), lung disease from chronic infection, single umbilical artery, absence of the hemidiaphragm, hypoplasia of the femora, ossification defects of the ischium and pubis, bilobed tongue, lung hypoplasia, and renal reflux.

Total anomalous pulmonary venous connection, also known as total anomalous pulmonary venous return, is a rare cyanotic congenital heart defect in which all four pulmonary veins are malpositioned and make anomalous connections to the systemic venous circulation. (Normally, pulmonary veins return oxygenated blood from the lungs to the left atrium where it can then be pumped to the rest of the body). A patent foramen ovale, patent ductus arteriosus or an atrial septal defect must be present, or else the condition is fatal due to a lack of systemic blood flow. In some cases, it can be detected prenatally.

Irish Setters tend to be a relatively healthy breed. Problems that have been noted in Irish Setters include hip dysplasia, cancer, progressive retinal atrophy (PRA), epilepsy, entropion, hypothyroidism, hyperosteodystrophy, gastric dilatation volvulus (bloat), osteosarcoma, Von Willebrand's disease, patent ductus arteriosus, canine Leukocyte adhesion deficiency (CLAD) and celiac disease. Irish Setters are now one of the few breeds for which genetic tests have been developed to detect the presence of both CLAD and PRA (RCD-1). Gluten intolerance in Irish Setters is a naturally occurring genetic disorder that is the result of a single autosomal recessive locus.

Male genitalia of Lepidoptera Female genitalia of Lepidoptera The study of the genitalia of Lepidoptera is important for Lepidoptera taxonomy in addition to development, anatomy and natural history. The genitalia are complex and provide the basis for species discrimination in most families and also in family identification. The genitalia are attached onto the tenth or most distal segment of the abdomen. Lepidoptera have some of the most complex genital structures in the insect groups with a wide variety of complex spines, setae, scales and tufts in males, claspers of different shapes and different modifications of the ductus bursae in females.

Prostaglandin E1 The treatment of pulmonary atresia consists of: an IV medication called prostaglandin E1, which is used for treatment of pulmonary atresia, as it stops the ductus arteriosus from closing, allowing mixing of the pulmonary and systemic circulations, but prostaglandin E1 can be dangerous as it can cause apnea. Another example of preliminary treatment is heart catheterization to evaluate the defect or defects of the heart; this procedure is much more invasive. Ultimately, however, the individual will need to have a series of surgeries to improve the blood flow permanently. The first surgery will likely be performed shortly after birth.

Whole body skeletal abnormalities are common in fetal warfarin syndrome. A generalized reduction in bone size causes rhizomelia; disproportionally short limbs, brachydactyly; short fingers and toes, a shorter neck, short trunk, scoliosis; abnormal curvature of the spine and stippled epiphyses; malformation of joints. Abnormalities of the chest: either pectus carinatum; a protruding sternum, or pectus excavatum; a sunken sternum form an immediately recognizable sign of fetal warfarin syndrome. Congenital heart defects such as a thinned atrial septum, coarctation of the aorta, patent ductus arteriosus; a connection between the pulmonary artery and aorta occur in 8% of fetal warfarin syndrome patients.

In terms of safety, ketorolac has been assessed to be a relatively higher-risk NSAID when compared to aceclofenac, celecoxib, and ibuprofen. Like all NSAIDs, ketorolac can cause premature constriction of the ductus arteriosus in the infant if taken by the mother during the third trimester of pregnancy. In October 2020, the U.S. Food and Drug Administration (FDA) required the drug label to be updated for all nonsteroidal anti-inflammatory medications to describe the risk of kidney problems in unborn babies that result in low amniotic fluid. They recommend avoiding NSAIDs in pregnant women at 20 weeks or later in pregnancy.

In skin, it is seen within the basement membrane of the dermoepidermal junction at points of nerve penetration. However, it was also found that the gamma 3 is a prominent element of the apical surface of ciliated epithelial cells of lung, oviduct, epididymis, ductus deferens, and seminiferous tubules. The distribution of gamma 3-containing laminins along ciliated epithelial surfaces suggests that the apical laminins are important in the morphogenesis and structural stability of the ciliated processes of these cells. A recent study found that LAMC3 plays a critical role in forming the convolution of the cerebral cortex.

John Mallon had a major influence on the French school of paleography, introducing and demonstrating the importance of the ductus as dynamic element of the evolution of writings. In the early years of his work, from 1937 to 1939, he retained the traditional theory that wanted all Roman writings were from the capital calligraphy by a regularly continuous transformation processing thereof, but highlighted the problems that this theory raised. He innovated by creating the first palaeographic movie, La lettre, which highlighted the role of successive actions of cursiveness and calligraphy on the morphological transformation of the alphabet. He published, with Robert Marichal, L'écriture latine de la capitale romaine à la minuscule.

The most common congenital heart defects (CHDs) which cause shunting are atrial septal defects (ASD), patent foramen ovale (PFO), ventricular septal defects (VSD), and patent ductus arteriosi (PDA). In isolation, these defects may be asymptomatic, or they may produce symptoms which can range from mild to severe, and which can either have an acute or a delayed onset. However, these shunts are often present in combination with other defects; in these cases, they may still be asymptomatic, mild or severe, acute or delayed, but they may also work to counteract the negative symptoms caused by another defect (as with d-Transposition of the great arteries).
|
|
Some acquired shunts are modifications of congenital ones: a balloon septostomy can enlarge a foramen ovale (if performed on a newborn), PFO or ASD; or prostaglandin can be administered to a newborn to prevent the ductus arteriosus from closing. Biological tissues may also be used to construct artificial passages. Evaluation can be done during a cardiac catheterization with a "shunt run" by taking blood samples from superior vena cava (SVC), inferior vena cava (IVC), right atrium, right ventricle, pulmonary artery, and system arterial. Abrupt increases in oxygen saturation support a left-to-right shunt and lower than normal systemic arterial oxygen saturation supports a right-to-left shunt.

Sir John Fraser, 1st Baronet, (23 March 1885 – 1 December 1947) was Regius Professor of Clinical Surgery at Edinburgh University from 1925 to 1944 and served as principal of the University of Edinburgh from 1944 to 1947. His study of tuberculosis in children was to disprove the view of the Nobel prize winner Robert Koch that bovine tuberculosis did not play a major pathogenic role in human disease. The subsequent legislation led to the elimination of tuberculosis from milk supplies and resulted in a decline in incidence of bone and joint tuberculosis in children. In 1940 he was the first surgeon in Britain to ligate an uninfected patent ductus arteriosus.

Among a number of curious inscriptions found at Armazi, the most important is the bilingual Greco- Aramaic tombstone inscription commemorating the short-lived Serapita and her noble lineage. It contains an unusual, in its ductus and some of its forms, version of the Aramaic alphabet which came to be known as the "Armazi script" although it can also be found outside Armazi, in other parts of Georgia. With the transfer of the Georgian capital to Tbilisi in the late 5th or early 6th century, Armazi went into a gradual decline. It still had its own high-ranking commandant, a post held in A.D. 545 by a certain Wistam.

All Spilomelinae moths have well developed compound eyes, antennae and mouthparts, although in the genera Niphopyralis and Siga the proboscis is lost. Synapomorphic characters of the subfamily comprise minute or obsolete maxillary palpi, ventrally projecting fornix tympani, and the female genitalia's ductus bursae with a weak sclerotization or a granulose texture. The moths are furthermore characterized by an often bilobed praecinctorium, pointed spinula, and the absence of chaetosemata and of a retinacular hook. A gnathos or pseudognathos can be present or absent and is therefore of little diagnostic value, except for several genera of Agroterini, where the gnathos has a well-developed medial process.

Ron Hodges created the genus in 1966 to accommodate three new species: two from North America and one from Chile. These he found very similar to the genus Batrachedra, but distinct on the basis of the adult males possessing a "single, strong, apical spine on the ampulla" (also known as the harpe), the females he distinguished from those of Batrachedra by the "presence of long apophyses" and the "absence of a signum and accessory pouches, and the corpus bursae being poorly set off from the ductus bursae". At the time Hodges initially classified the genus in the family Gelechioidea. Hodges designated as type species Chedra pensor.

The sperm, when released from the capsule, swims directly into or via a small tube (the 'ductus bursae') into a special seminal receptacle (the 'spermatheca'), where the sperm is stored until it is released into the vagina for fertilisation during egg laying, which may occur hours, days, or months after mating. The eggs pass through the ovipore. The ovipore may be at the end of a modified 'ovipositor' or surrounded by a pair of broad setose anal papillae. Butterflies of the Parnassinae (Family Papilionidae) and some Acraeini (Family Nymphalidae) add a post-copulatory plug, called the sphragis, to the abdomen of the female after copulation preventing her from mating again.

In people with HLHS, the aorta and left ventricle are underdeveloped (beginning in utero), and the aortic and mitral valves are either too small to allow sufficient blood flow or are atretic (closed) altogether. As blood returns from the lungs to the left atrium, it cannot be pumped to the rest of the body by the left ventricle. The neonate is reliant on blood flowing through an atrial septal defect to mix oxygenated and deoxygenated blood, and on a patent ductus arteriosus to allow blood to reach the aorta and the systemic circulation via the right ventricle. This is what defines HLHS as a "single ventricle" defect.

The contribution of Opus Geometricum was in :making extensive use of spatial imagery to create a multitude of solids, the volumes of which reduce to a single construction depending on the ductus of a rectilinear figure, in the absence of [algebraic notation and integral calculus] systematic geometric transformation fulfilled an essential role. For example, the "ungula is formed by cutting a right circular cylinder by means of an oblique plane through a diameter of the circular base." And also the "’double ungula formed from cylinders with axes at right angles." Ungula was changed to "onglet" in French by Blaise Pascal when he wrote Traité des trilignes rectangles et leurs onglets.

Ibuprofen and naproxen have not frequently been studied during pregnancy, but recent studies do not show increased risk of spontaneous abortion within the first six weeks of pregnancy. However, all NSAIDs showed association with structural cardiac defects with usage during the early weeks of pregnancy. When ibuprofen and naproxen are used within the third trimester, there is a significant increase in the risk of premature closure of the ductus arteriosus with primary pulmonary hypertension in the newborn. Between the lack of studies of the effect of ibuprofen and naproxen on pregnancy, it is recommended that pregnant women avoid these medications or use them sparingly per physician recommendations.

In the developing embryo, at the hind end lies a cloaca. This, over the fourth to the seventh week, divides into a urogenital sinus and the beginnings of the anal canal, with a wall forming between these two inpouchings called the urorectal septum. Two ducts form next to each other that connect to the urogenital sinus; the mesonephric duct and the paramesonephric duct, which go on to form the reproductive tracts of the male and female respectively. In the male, under the influence of testosterone, the mesonephric duct proliferates, forming the epididymis, ductus deferens and, via a small outpouching near the developing prostate, the seminal vesicles.

Adult Trichaeini are characterised by a single synapomorphy in the male genitalia: a raised sclerotised ridge is present on the sacculus, running from the basal to the dorsodistal part. Further characteristics of Trichaeini are the weakly sclerotised, lens-shaped valvae, the strongly (in Trichaea and Archernis humilis) to weakly sclerotized fibula with simple hairs, and the scaly sacculus. In the female genitalia, the ductus bursae is broad, but narrowing at the posterior end, and the corpus bursae bears a slim longitudinal signum. In some Prophantis species, the anterior end of the signum is split into two anterolateral legs – a condition that is also found in Syngamia in the Nomophilini.

The first successful operation to treat blue baby syndrome caused by Tetralogy of Fallot occurred at Johns Hopkins University in 1944. Through a collaboration between pediatric cardiologist Helen Taussig, surgeon Alfred Blalock, and surgical technician Vivien Thomas, the Blalock-Thomas-Taussig shunt was created. Dr. Taussig had recognized that children with Tetralogy of Fallot who also had a patent ductus arteriosus (PDA) typically lived longer, so the trio tried to create the same effect as a PDA by joining the subclavian artery to the pulmonary artery, relieving the child's cyanosis. The operation was published in the Journal of the American Medical Association in 1945 and impacted management of blue babies around the world.

When pulmonic stenosis (PS) is present, resistance to blood flow causes right ventricular hypertrophy. If right ventricular failure develops, right atrial pressure will increase, and this may result in a persistent opening of the foramen ovale, shunting of unoxygenated blood from the right atrium into the left atrium, and systemic cyanosis. If pulmonary stenosis is severe, congestive heart failure occurs, and systemic venous engorgement will be noted. An associated defect such as a patent ductus arteriosus partially compensates for the obstruction by shunting blood from the left ventricle to the aorta then back to the pulmonary artery (as a result of the higher pressure in the left ventricle) and back into the lungs.

Browne studied and influenced the surgical management of a wide variety of problems, including cleft lip and palate, patent ductus arteriosus, intestinal obstruction and genitourinary problems. He paid special attention to the surgical problems of newborns, and he introduced new thoughts on the development and management of conditions such as club foot and hypospadias. In formulating his version of the hypospadias repair, Browne knew that fistulae lined with epithelium would not close, so he created a fistula between the hypospadias and the similarly lined tip of the penis. He also realised that one of the common steps in such repairs – the transfer of skin from the foreskin to the ventral surface of the penis – was unnecessary.

When occurring genetically within the eyes or ears, this white mutation can be detrimental to development, causing hearing or vision problems. Other dachshund health problems include hereditary epilepsy, granulomatous meningoencephalitis, dental issues, Cushing's syndrome, thyroid and autoimmune problems, various allergies and atopies, and various eye conditions including cataracts, glaucoma, progressive retinal atrophy, corneal ulcers, nonucerative corneal disease, sudden acquired retinal degeneration, and cherry eye. Dachshunds are also 2.5 times more likely than other breeds of dogs to develop patent ductus arteriosus, a congenital heart defect. Dilute color dogs (Blue, Isabella, and Cream) are very susceptible to color dilution alopecia, a skin disorder that can result in hair loss and extreme sensitivity to sun.

Individuals that are 46, XY and have been tested positive for mutations in their AMH or AMH receptor genes have been known to exhibit features typical of that which are exhibited in persistent müllerian duct syndrome due to the fact that the paramesonephric ducts fail to regress. When this happens the individuals develop structures that are derived from the paramesonephric duct, and also structures that are derived from the mesonephric duct. A male that has persistent müllerian duct syndrome may have an upper vagina, uterus, and uterine tubes as well as ductus deferens along with male external genitalia. The female organs are in the correct anatomical position but the position of the testis varies.

In the pelvic cavity this vessel is in relation, laterally, with the obturator fascia; medially, with the ureter, ductus deferens, and peritoneum; while a little below it is the obturator nerve. Inside the pelvis the obturator artery gives off iliac branches to the iliac fossa, which supply the bone and the Iliacus, and anastomose with the ilio-lumbar artery; a vesical branch, which runs backward to supply the bladder; and a pubic branch, which is given off from the vessel just before it leaves the pelvic cavity. The pubic branch ascends upon the back of the pubis, communicating with the corresponding vessel of the opposite side, and with the inferior epigastric artery.

This open-heart surgery is designed to relieve the right ventricular outflow tract stenosis by careful resection of muscle and to repair the VSD. Additional reparative or reconstructive surgery may be done on patients as required by their particular cardiac anatomy. Timing of surgery in asymptomatic patients is usually between the ages of 2 months to one year. However, in symptomatic patients showing worsening blood oxygen levels, severe tet-spells (cyanotic spells), or dependence on prostaglandins from early neonatal period (to keep the ductus arteriosus open) need to be planned fairly urgently Potential surgical repair complications include residual ventricular septal defect, residual outflow tract obstruction, complete atrioventricular block, arrhythmias, aneurysm of right ventricular outflow patch, and pulmonary valve insufficiency.

Illustration of arterial switch operation Illustration of arterial switch operation The heart is accessed via median sternotomy, and the patient is given heparin to prevent the blood from clotting. A generous section of pericardium is harvested, then disinfected and sterilized with a weak solution of glutaraldehyde; and the coronary and great artery anatomy are examined. The ductus arteriosus and right pulmonary branch, up to and including the first branches in the hilum of the right lung, are separated from the surrounding supportive tissue to allow mobility of the vessels. Silk marking sutures may be placed in the pulmonary trunk at this time, to indicate the commissure of the aorta to the neo-aorta; alternatively, this may be done later in the procedure.

The volume of an ungula of a cylinder was calculated by Grégoire de Saint Vincent.Gregory of St. Vincent (1647) Opus Geometricum quadraturae circuli et sectionum coni Two cylinders with equal radii and perpendicular axes intersect in four double ungulae.Blaise Pascal Lettre de Dettonville a Carcavi describes the onglet and double onglet, link from HathiTrust The bicylinder formed by the intersection had been measured by Archimedes in The Method of Mechanical Theorems, but the manuscript was lost until 1906. A historian of calculus described the role of the ungula in integral calculus: :Grégoire himself was primarily concerned to illustrate by reference to the ungula that volumetric integration could be reduced, through the ductus in planum, to a consideration of geometric relations between the lies of plane figures.

Eisenmenger's syndrome is defined as the process in which a long-standing left-to-right cardiac shunt caused by a congenital heart defect (typically by a ventricular septal defect, atrial septal defect, or less commonly, patent ductus arteriosus) causes pulmonary hypertension and eventual reversal of the shunt into a cyanotic right-to-left shunt. Because of the advent of fetal screening with echocardiography early in life, the incidence of heart defects progressing to Eisenmenger's has decreased. Eisenmenger's syndrome in a pregnant mother can cause serious complications, though successful delivery has been reported. Maternal mortality ranges from 30% to 60%, and may be attributed to fainting spells, blood clots forming in the veins and traveling to distant sites, hypovolemia, coughing up blood or preeclampsia.

N Engl J Med 1945;233:586 Gross is one of the pioneers of cardiovascular surgery, who also performed the first successful ligation of a patent ductus arteriosus 7 years earlier. The basis for the radiologic diagnosis by barium swallow (esophagram) of double aortic arch (and other forms of vascular rings) was described in 1946 by Neuhauser from the same institution.Neuhauser EB. The roentgen diagnosis of double aortic arch and other anomalies of the great vessels. Am J Roentgenol Radium Ther Nucl Med 1946;56:1 Certain types of double aortic arch with a left arch that is small in diameter (less than 2 or 3mm patent) or atretic might be suitable for a so-called minimally invasive video-assisted thoracoscopic surgery (VATS) approach.

Due to the sheer number of taxa contained here, this has not been thoroughly tested, and some little- known genera traditionally included in the Phycitinae may of course simply be convergent and do not really belong here. Altogether however, the mesothorax of the caterpillars - with the sclerotised (hardened) ring around the base of seta SD1 - as well as the identical frenula of male and female adults' wings - a single bristle composed of several acanthae - are held to be characteristic autapomorphies by which the Phycitinae can be recognized. Furthermore, in the female genitalia of this subfamily the ductus seminalis originates in the corpus bursae. A useful character in the field is that the forewings of many adult Phycitinae lack one or more veins, usually the seventh one.

This was in stark contrast to many of the anatomical models used previously, which had strong Galenic/Aristotelean elements, as well as elements of astrology. Although modern anatomical texts had been published by Mondino and Berenger, much of their work was clouded by reverence for Galen and Arabian doctrines. Besides the first good description of the sphenoid bone, he showed that the sternum consists of three portions and the sacrum of five or six, and described accurately the vestibule in the interior of the temporal bone. He not only verified Estienne's observations on the valves of the hepatic veins, but also described the vena azygos, and discovered the canal which passes in the fetus between the umbilical vein and the vena cava, since named the ductus venosus.

Scottish pathologist Matthew Baillie first described TGA in 1797, presumably as a posthumous diagnosis. Early mortality rates at this time are estimated to have been as high as 90%; the survivors would have been those with one or more concomitant intracardiac shunts (ASD, patent ductus arteriosus (PDA), patent foramen ovale (PFO), and/or VSD), and are unlikely to have survived past adolescence. In 1950, American surgeons Alfred Blalock and C. Rollins Hanlon introduced the Blalock-Hanlon atrial septectomy, which was then routinely used to palliate patients. This would have effectively reduced early mortality rates, particularly in cases with no concomitant shunts, but is unlikely to have reduced late mortality rates. Mustard first conceived of, and attempted, the anatomical repair (arterial switch) for d-TGA in the early 1950s.

In females, the ductus bursae is kinked at the junction of the forward (membranous) and hind (sclerotized) parts, with a particularly heavy sclerotized triangle bearing small teeth half-hidden in the kink.Clarke (1986) They are common across the world's continents except in deserts, on high mountains, and in glaciated areas. In addition, they are apparently even able to disperse over water well, as evidenced by the Polynesian radiations which occur mainly from Hawaiian Islands to the Austral Islands as well as on New Zealand; several of these island endemics might nowadays be rare or extinct due to disappearance of their food plants, but overall the genus is not yet very well studied. As far as is known, the caterpillar larvae of most Eudonia feed on mosses, namely of subclasses Bryidae and Dicranidae; some also eat lichen.

The great arteries originate from the aortic arches during embryonic development. The aortic arches start as five pairs of symmetrical vessels connecting the heart with the dorsal aorta but then undergo a significant remodelling, in which some of these vessels regress (aortic arches 1 and 2), the 3rd pair of arches contribute to form the common carotids, the right 4th will contribute to the base and central part of the right subclavian artery, while the left 4th will form the central portion of the aortic arch. The 5th pair of vessels only form in some cases without any known contribution to the final structure of the great arteries. The right 6th almost completely regresses with only the proximal part contributing to the base of the pulmonary arteries, while the left 6th forms the ductus arteriosus, which disappears after birth.

The classification system (Types A, B, and C) were defined by Celoria and Patton in 1959. The first successful repair of a Type A interrupted aortic arch was reported in 1961, in which the left subclavian artery was grafted into the descending thoracic aorta in a 14-year-old male patient. The first successful repair of a Type A interrupted aortic arch in an infant was in a 12-day-old infant in 1969, in which the left subclavian artery was connected to the descending thoracic aorta, the patent ductus arteriosus was closed, and the main pulmonary artery was banded. The first successful repair of a Type B interrupted aortic arch was in 1954, in which the 16 year-old, female patient's own aorta was grafted from the arch to the descending thoracic aorta and the left subclavian artery was ligated.

In addition, tetralogy of Fallot may present with other anatomical anomalies, including: # stenosis of the left pulmonary artery, in 40% # a bicuspid pulmonary valve, in 60% # right-sided aortic arch, in 25% # coronary artery anomalies, in 10% # a patent foramen ovale or atrial septal defect, in which case the syndrome is sometimes called a pentalogy of Fallot # an atrioventricular septal defect # partially or totally anomalous pulmonary venous return Tetralogy of Fallot with pulmonary atresia (pseudotruncus arteriosus) is a severe variant in which there is complete obstruction (atresia) of the right ventricular outflow tract, causing an absence of the pulmonary trunk during embryonic development. In these individuals, blood shunts completely from the right ventricle to the left where it is pumped only through the aorta. The lungs are perfused via extensive collaterals from the systemic arteries, and sometimes also via the ductus arteriosus.

He was born at Florence on the September 3, 1643. At the age of twenty, when he had already begun his researches on the structure of the kidneys and had described the papillary ducts (also known as Bellini's ducts; latin: ductus Bellini, tubulus Bellini, tubuli Belliniani; see: duct of bellini, bellini duct carcinoma), as published in his book Exercitatio Anatomica de Structura Usu Renum (1662), he was chosen professor of theoretical medicine at Pisa, but soon after was transferred to the chair of anatomy. After spending thirty years at Pisa, he was invited to Florence and appointed physician to the grand duke Cosimo III, and was also made senior consulting physician to Pope Clement XI. He died at Florence on the January 8, 1704. His works were published in a collected form at Venice in 1708.

The primitive mesentery of a six weeks’ human embryo, half schematic. (Lesser omentum labeled at left.) Schematic and enlarged cross-section through the body of a human embryo in the region of the mesogastrium, at end of third month The lesser omentum is extremely thin, and is continuous with the two layers of peritoneum which cover respectively the antero-superior and postero-inferior surfaces of the stomach and first part of the duodenum. When these two layers reach the lesser curvature of the stomach and the upper border of the duodenum, they join together and ascend as a double fold to the porta hepatis. To the left of the porta, the fold is attached to the bottom of the fossa for the ductus venosus, along which it is carried to the diaphragm, where the two layers separate to embrace the end of the esophagus.

The 2008 film Gran Torino, directed by Clint Eastwood, was the first mainstream US film to feature Hmong Americans. Eastwood plays Walt Kowalski, an elderly, racist Korean War veteran living in Detroit, Michigan who befriends a Hmong teenager named Thao, played by Bee Vang, who previously tries to steal his Gran Torino as an initiation into a local Hmong gang run by his own cousins. In the episode Body & Soul of the TV series House, the team treats a Hmong child that is believed to be possessed by a dab, which the doctors, as well the child's mother attempt to disprove. Following an exorcism in order to free the dab from the child, his symptoms go away, which his mother and grandfather attribute to the exorcism, while the doctors believe it was the long shot treatment of Ibuprofen to treat his Patent ductus arteriosus that cured him.

Adult Endotricha flammealis of the Endotrichini in typical resting pose This subfamily unites generally mid-sized to smallish moths with a more or less cryptic coloration including most often various hues of brownish colors. Adult females of Pyralinae (except Cardamyla and Embryoglossa) are characterized by the short genital ductus bursae, their corpus bursae barely extending forward beyond abdominal segment 7. Otherwise they are rather nondescript mid-sized moths (large by Pyralidae standards) which at least sometimes can be distinguished from their relatives by possessing forewing vein 7 and having hindwing veins 7 and 8 unjoined as adults.Clarke (1986), Solis (2007) The meal moth (Pyralis farinalis) and the grease moth (Aglossa pinguinalis) are pests of stored food products, in the case of the grease moth including fats (which are also eaten by the adult moths), and have been inadvertently spread almost worldwide by transport of such goods.

Dr. William Ladd, a doctor with Children's, devised procedures for correcting various congenital defects such as intestinal malformations in 1920, launching the specialty of pediatric surgery. Dr. Robert E. Gross, a surgeon at Children's and later a professor of child surgery at Harvard Medical School, performed the world's first successful surgical procedure to correct a congenital cardiovascular defect with the "ligation of a patent ductus arteriosus" in 1938, ushering in the era of modern pediatric cardiac surgery. Dr. Sidney Farber, pediatric pathologist, requested Dr. Yellapragada Subbarow (of Lederle lab and his friend and colleague at Harvard Medical School) to supply Aminopterin and later Amethopterin (Methotrexate) to conduct trials on to children with leukemia, a diagnosis that was deemed a "death sentence," in 1948. He achieved the world's first partial remission of acute leukemia. He went on to co-found the Dana- Farber Cancer Institute in 1950.

Although sebaceous gland activity in the skin increases during the late stages of pregnancy, pregnancy has not been reliably associated with worsened acne severity. In general, topically applied medications are considered the first-line approach to acne treatment during pregnancy, as they have little systemic absorption and are therefore unlikely to harm a developing fetus. Highly recommended therapies include topically applied benzoyl peroxide (pregnancy category C) and azelaic acid (category B). Salicylic acid carries a category C safety rating due to higher systemic absorption (9–25%), and an association between the use of anti-inflammatory medications in the third trimester and adverse effects to the developing fetus including too little amniotic fluid in the uterus and early closure of the babies' ductus arteriosus blood vessel. Prolonged use of salicylic acid over significant areas of the skin or under occlusive (sealed) dressings is not recommended as these methods increase systemic absorption and the potential for fetal harm.

In the genitalia of H. quindiensis there are two rather than three coils in the vesica and appendix bursae and only the posterior half of the ductus bursae is sclerotized. Hypotrix purpurigera and several of its South American relatives also have black reniform and orbicular spots that are frequently fused posteriorly, creating a wide V-shaped mark. Within the North American fauna the male genitalia of Hypotrix lunata are most similar to those of Hypotrix hueco, but differ in that only the apical part of the uncus is expanded in H. lunata whereas the apical 2/3 is wide in H. hueco, the clasper is stouter and abruptly tapered apically in H. lunata, and the dorsal lobe on the sacculus is much larger. The vesica is very different from that of H. hueco in having much more extensive basal cluster of spines and subbasal cornuti in a longitudinally ribbed basal swelling, and the vesica has three tight medial coils rather than one as in H. hueco.

The vestibule is somewhat oval in shape, but flattened transversely; it measures about 5 mm from front to back, the same from top to bottom, and about 3 mm across. In its lateral or tympanic wall is the oval window (fenestra vestibuli), closed, in the fresh state, by the base of the stapes and annular ligament. On its medial wall, at the forepart, is a small circular depression, the recessus sphæricus, which is perforated, at its anterior and inferior part, by several minute holes (macula cribrosa media) for the passage of filaments of the acoustic nerve to the saccule; and behind this depression is an oblique ridge, the crista vestibuli, the anterior end of which is named the pyramid of the vestibule. This ridge bifurcates below to enclose a small depression, the fossa cochlearis, which is perforated by a number of holes for the passage of filaments of the acoustic nerve which supply the vestibular end of the ductus cochlearis.
