Gastric duplication cysts comprise 2-7% of gastrointestinal duplications, rare congenital malformations that can be present at almost any part of the alimentary tract. They mostly present with gastrointestinal obstruction symptoms, ulceration, and painless hemorrhage. Symptoms include nausea, vomiting, and fullness sensation. Gastric duplications are mostly cystic in shape. Herein, we present a...

Alimentary tract duplications are rare congenital malformations that may be found anywhere from mouth to anus. They usually share a common smooth muscle wall and blood supply with the adjacent bowel. Some duplications are asymptomatic but most cause problems in early childhood. Gastric duplications account for 2% to 7% of all gastrointestinal duplications. The management of gastric duplication ...

A type 1 pilus-deficient mutant of a systemically invasive Escherichia coli K1 strain was constructed by directed mutagenesis of pilA, the gene that codes for the major structural subunit of type 1 pili. By comparing this mutant with an isogenic pilA+ strain, we were able to assess the role of type 1 piliation in alimentary tract colonization and bloodstream invasion in neonatal rats. Intestina...

The labial minor salivary glands (LSGs) are easily accessible mucus-secreting structures of the alimentary tract that may provide new information on the basis of gastrointestinal complications of cystic fibrosis (CF). It was shown that they are destructed in the course of cystic fibrosis. We employed wide-field, micrometer resolution in vivo optical coherence tomography to assess the surface de...

The contents of the lower alimentary tract from rats fed a semisynthetic, pectin-supplemented diet showed increased nitrate reductase activity and an increase in the amount of luminal contents in the intestine and cecum. Nitrate reductase activity was associated with the insoluble fraction of the gut contents which was sedimented by centrifugation (5,100 X g,20 min) and was abolished after trea...

This high incidence of the upper alimentary tract carcinomas in India obviously cannot be accidental. A previous study (Shanta and Krishnamurthi, 1959) suggested that the critical factors were essentially environmental and that any racial pre-disposition could be totally excluded. That study also eliminated preexisting diseases like tuberculosis, diabetes, virus infections, etc., as of any sign...
