Macchiarini, who denied any negligence in his transplant of synthetic tracheas into the three patients in 2011-12, was fired from Karolinska Hospital in March 2016.

Unlike humans, who have larynxes near the top of their tracheas, birds have a system called a syrinx at the bottom of their trachea, where it splits into either lung.

More practically, the technique could be used to facilitate other types of biological implants, such as bioengineered organs, tissues, and limbs—from bladders, hearts, and tracheas through to eyes, ears and sensitive skin.

On May 8, a team of medical researchers published an article in the journal Experimental Lung Research in which they reported creating an animal model of burn-pit symptoms by injecting samples of dust collected from Iraq's Camp Liberty base into the tracheas of mice.

An investigation last week showed three operations conducted at the Karolinska University Hospital in which Macchiarini transplanted synthetic tracheas coated with stem cells were performed before sufficient study had been done on the procedure and that the operations could not be justified on the grounds of being life-saving.

Syngamus merulae is a parasitic nematode worm infecting the tracheas of birds including thrushes. It is closely related to the gapeworm, Syngamus trachea.Rothschild & Clay (1953) p. 181.

The Varroa mite is also a member of this subclass and therefore treatments against Varroa in its phoretic stage will also be effective against Acarapis woodi. In 2004 research was conducted to determine how the differences in the tracheas of various subspecies of Apis mellifera related to Acarapis woodi, it was found that A. m. macedonica, in which the Acarapis woodi are absent, has significantly smaller (up to 21%) measurements for its tracheas when compared to A. m. carnica and A. m.

RVI-ID is often misdiagnosed, but if correctly diagnosed, is treatable. Symptoms may include: symmetrical dark spots or lesions at the tips of the ears; swelling, hard lumps or dark spots in the vicinity of the injection site. Higher volume Norwich breeders are seeing more dogs with breathing concerns, and the Norwich and Norfolk Terrier Club (USA) has formed a new "Health and Genetics Sub-Committee for Research on Upper Airway Syndrome in Norwich Terriers"."The Norwich & Norfolk News," Number 93, Fall 2006 Upper Airway Syndrome (UAS) covers all abnormalities that can occur in the upper airway, including: elongated soft palates; too short soft palates; narrow/misshapen tracheas; collapsing tracheas; stenotic nares (nasal passages that are too small); swollen tonsils; everted laryngeal saccules.

One of the concerns at this time was the worry that using high pressures of oxygen could be damaging to newborn lungs. Barrie developed an underwater safety valve in the oxygen circuit. The tubes were originally made of rubber, but these had the potential to cause irritation to sensitive newborn tracheas: Barrie switched to plastic. This new endotracheal tube, based on Barrie's design, was known as the ‘St Thomas’s tube’.

From 2008, operations have experimentally replaced tracheas, with those grown from stem cells, or with synthetic substitutes, however this is regarded as experimental and there is no standardised method. Difficulties with ensuring adequate blood supply to the replaced trachea is considered a major challenge to any replacement. Additionally, no evidence has been found to support the placement of stem cells taken from bone marrow on the trachea as a way of stimulating tissue regeneration, and such a method remains hypothetical.

When not oxygenated, hemolymph quickly loses its color and appears grey. The hemolymph of lower arthropods, including most insects, is not used for oxygen transport because these animals respirate through other means, such as tracheas, but it does contain nutrients such as proteins and sugars. Muscular movements by the animal during locomotion can facilitate hemolymph movement, but diverting flow from one area to another is limited. When the heart relaxes, blood is drawn back toward the heart through open-ended pores called ostia.

Tracheas are an important area of the respiratory tract; aside from directing air in and out of the lungs, it has the largest volume of dead space in the tract. Dead space in avians is around 4.5 times higher in mammals of roughly the same size. In particular, flamingos have a trachea that is longer than its body length with 330 cartilaginous rings. As a result, they have a calculated dead space twice as high as another bird of the same size.

This is a syndrome occurs in French bulldogs and causes them to have multiple side effects as in difficulty breathing (which includes snoring, loud breathing). It happens in French bulldogs because they have narrow nostril openings, a long soft palate and fairly narrow tracheas. This issue can lead to death in French Bulldogs if they are not undergoing proper treatment. Increased factors should be taken into account like weather conditions and if the dog is high energy/excitement, or if the dog has any possible allergies.

Of secondary magnitude, cataracts are recognized as a disorder that has been reported sporadically and may be inherited. Also of a secondary magnitude there are instances of epilepsy, narrow tracheas, luxating patellas, hip dysplasia, mitral valve disease, portosystemic shunts, atopy(allergic inhalant dermatitis) and incorrect bites (how the teeth meet when the jaws are closed). Like all dogs, Norwich Terriers can have autoimmune reactivity to rabies vaccinations. Rabies-Vaccine-Induced Ischemic Dermatopathy, or RVI-ID, is a non-fatal but potentially serious reaction to chemicals called adjuvants in the vaccine.

Equipped with three types of waterproof wheelchairs, Wheelchair Valet is home to seven accessible changing rooms, Hoyer lifts, and adult-sized changing tables for guest use. Wheelchair users have the opportunity to transfer into complimentary waterproof wheelchairs, as well as free waterproof bags for ventilators and O2 water-collar covers for guests who need to cover tracheas. Morgan's Inspiration Island offers tilt and space chairs, manual/rigid chairs, and PneuChair pneumatic wheelchairs in multiple sizes. The PneuChair, a waterproof motorized wheelchair that runs entirely on compressed air, was developed by the University of Pittsburgh's Human Engineering Research Laboratories (HERL).

The bronchi split into smaller branches and then to bronchioles that supply air to the alveoli, the tiny air-filled sacs in the lungs responsible for absorbing oxygen. An arbitrary division can be made between the intrathoracic and cervical trachea at the thoracic inlet, an opening at the top of the thoracic cavity. Anatomical structures that surround and protect the tracheobronchial tree include the lungs, the esophagus, large blood vessels, the rib cage, the thoracic spine, and the sternum. Children have softer tracheas and a more elastic tracheobronchial trees than adults; this elasticity, which helps protect the structures from injury when they are compressed, may contribute to the lower incidence of TBI in children.

Recent studies have discovered that chorionic villi can be a rich source of fetal stem cells, multipotent mesenchymal stem cells A potential benefit of using fetal stem cells over those obtained from embryos is that they side-step ethical concerns among anti-abortion activists by obtaining pluripotent lines of undifferentiated cells without harm to a fetus or destruction of an embryo. These stem cells would also, if used to treat the same individual they came from, sidestep the donor/recipient issue which has so far stymied all attempts to use donor-derived stem cells in therapies. Artificial heart valves, working tracheas, as well as muscle, fat, bone, heart, neural and liver cells have all been engineered through use of fetal stem cells The first fetal stem cells bank in US is active in Boston, Massachusetts.

The field of artificial tracheas went through a period of high interest and excitement with the work of Paolo Macchiarini at the Karolinska Institute and elsewhere from 2008 to around 2014, with front-page coverage in newspapers and on television. Concerns were raised about his work in 2014 and by 2016 he had been fired and high level management at Karolinska had been dismissed, including people involved in the Nobel Prize. As of 2017 engineering a trachea—a hollow tube lined with cells—had proved more challenging then originally thought; challenges include the difficult clinical situation of people who present as clinical candidates, who generally have been through multiple procedures already; creating an implant that can become fully developed and integrate with host while withstanding respiratory forces, as well as the rotational and longitudinal movement the trachea undergoes.

In late 2004, People for the Ethical Treatment of Animals (PETA) released a video filmed undercover at Agriprocessors, showing gory details of cattle having their tracheas and esophagi ripped out of their necks and surviving for minutes after shechita (ritual slaughter).PETA Video showing animal abuse (Caution: graphic) Noted animal welfare expert and meat scientist Dr. Temple Grandin called Agriprocessors procedures an "atrocious abomination" and worse than anything she had ever seen in over 30 kosher abattoirs. Jewish authorities were split, with former Chief Rabbi of Ireland, David Rosen,Statement of Rabbi David Rosen, Former Chief Rabbi of Ireland and Shechita UK, along with many non- Orthodox rabbis from the Conservative movement, criticizing Agriprocessors, while Orthodox kashrut organizations continued to stand by the kashrut of the meat. Under pressure from the Agriculture Department, the Orthodox Union kosher certification authority, and Israel's chief rabbinate, the plant changed its practices.
