A form of congenital hypotrichosis, commonly known as rat-tail, is characterized by the colored hair anywhere on the body being short, curly, malformed, and sometimes sparse and an abnormal tail switch. The "rat-tail" syndrome is controlled by interaction between two loci.
Rat-tail appearance on barium swallow is a characteristic sign of achalasia cardia but rarely it can occur due to other causes like carcinoma of esophagus and in infections like tuberculosis or chagas disease.
In cattle most tail defects are considered to have genetic origins (Schalles and Cundiff, 1999; Belge et al., 2000) and these abnormalities mostly appear in the process of crossing different breeds (Hills, 1997; Bahr and Distl, 2005).
Rat Tails. This casting defect occur in the casting as an irregular line or cracks. The rat tail appear on casting when hotness of the metal causes the sand to expand which may be caused by poor expansion properties of the sand, hot pouring temperature of metal, and poor design.
On the barium swallow study, a dilated esophagus tapering at the distal end, which is referred to as 'rat's tail' or 'bird's beak' appearance. The 'rat's tail' sign is typical of idiopathic achalasia; however, a small proportion occurs secondary to other conditions, such as esophageal cancer or Chagas' disease.
Rat's tails are unmistakable – they are thick, long, hairless, and scaly. Tails are one of the primary ways to distinguish rodents. Mice have long tails, but they are hair-covered. Rat's tails average 10-24cm long, depending on maturity.
In achalasia, the muscles in the oesophagus do not contract correctly and the ring of muscle can fail to open properly, or does not open at all. Food and drink cannot pass into the stomach and becomes stuck. It is often brought back up.
The style found its niche in the gritty underground of the punk subculture in the mid to late 1980s. As the mullet began to oversaturate the mainstream, the rat tail offered a more unusual alternative. It wasn't just a hairstyle; it was a bold political statement, declaring a decree of defiance and individuality.
Common findings in dogs with hypothyroidism include: Hair loss or thinning of the fur—this occurs mainly over the dog's trunk, sparing the head and legs. Often, the hair loss starts on the tail leading to a “rat tail” appearance. A bald area around the collar is also common.
Other potential causes of weak and stillborn calves are brucellosis, anaplasmosis, neosporosis, BVD, IBR, Blue Tongue disease, and nitrate toxicity. Cattle producers should have a diagnostic plan in case this occurs. While a diagnosis is not always reached, “negative” results can help rule out some problems.
Heiferette. A female bovine, 2 ½ years old or younger that exhibits cow characteristics, that has not had her first calf or recently lost her first calf.
Technical Abstract: A form of congenital hypotrichosis, commonly known as the rat-tail syndrome, occurs in a small percentage of calves produced by crossing some Continental breeds cattle with breeds that are black in color.
The rattail can be traced back to China during the 17th Century when the Manchu took over and established the Qing Dynasty. It was known as the Manchu Queue. In the 1980's Vietnamese refugees fled to Australia/USA. The Vietnamese youths were known to have rattails and popularized it throughout western culture.
Color dilution variants in the PMEL17 gene are associated with “rat-tail syndrome” (RTS), a form of congenital hypotrichosis characterized by misshaped, curly and sparse dilute colored hair, and by missing hairs at the tail switch. RTS-affected animals have health and growth performance impairments.
Ringtail is a pathologic condition of the tail of rats and other rodents that is traditionally attributed to low environmental humidity, although dietary deficiencies, genetic susceptibility, environmental temperature, and degree of hydration of the animal also have been suggested as possible causes.
Keeping a wound clean and covering it with a layer of petroleum jelly, such as plain Vaseline, can retain moisture and prevent a wound from scabbing over.
Cold Shuts
A cold shut occurs when the molten material has begun to solidify before fully filling the mould. When the molten metal begins solidifying before the mould has been completely filled, it can form a seam that hasn't merged correctly. This results in severe weak spots in the casting.
Factors that can slow the wound healing process include: Dead skin (necrosis) – dead skin and foreign materials interfere with the healing process. Infection – an open wound may develop a bacterial infection. The body fights the infection rather than healing the wound.
Other forms: rattails. Definitions of rattail. deep-sea fish with a large head and body and long tapering tail. synonyms: grenadier, rattail fish. gadoid, gadoid fish.
Analysis showed that the rat-tail syndrome is controlled by interacting genes at two loci. Cattle that express the syndrome must have at least one dominant gene for black color and be heterozygous at the other locus involved.
High-protein foods, such as lean meats, fish, eggs, tofu, and legumes increase the pressure of the lower esophageal sphincter and are recommended to increase satiety and prevent acid reflux symptoms.
Eosinophilic esophagitis (e-o-sin-o-FILL-ik uh-sof-uh-JIE-tis) is a chronic immune system disease. With this disease, a type of white blood cell, called an eosinophil, builds up in the lining of the tube that connects your mouth to your stomach. This tube is also called the esophagus.
Medicines to relax your swallowing muscles.
Peppermint oil, onabotulinumtoxinA (Botox) injections into the esophagus or calcium channel blockers, such as diltiazem (Cardizem, Tiazac, others), can make spasms less severe.
