Determination of normal gastric emptying time and small intestinal transit time are useful in detecting gastrointestinal motility disorders and partial obstructions of the pylorus or small intestine. This study was conducted to evaluate iodixanol as a contrast agent in the gastrointestinal tract in New Zealand White rabbit. Twelve clinically healthy adult rabbits were prepared and kept for two ...

ABSTRACT: This study assessed microscopic morphology of protozoan and metazoan parasites, as well parasite-associated histopathologic changes in five Brazilian free-ranging armadillos. Three armadillos had intra sarcolemmal cysts Sarcocystis sp. skeletal muscles without changes. One Dasypus novemcinctus was found parasitized with a nematode morphologically compatible an oxyurid the small intest...

The horse has a rich and complex microbial community within its gastrointestinal tract that plays a central role in both health and disease. The horse receives much of its dietary energy through microbial hydrolysis and fermentation of fiber predominantly in the large intestine/hindgut. The presence of a possible core bacterial community in the equine large intestine was investigated in this st...

The intestine is one of the major organs in C. elegans and is largely responsible for food digestion and assimilation as well as the synthesis and storage of macromolecules. In addition, the intestine is emerging as a powerful experimental system in which to study such universal biological phenomena as vesicular trafficking, biochemical clocks, stress responses and aging. The present chapter de...

Radiation-induced intestinal injury is a common complication in radiotherapy for the cancer located in abdomen or pelvis. However, there is no effective treatment for radiation-induced intestinal injury now. It is therefore important to develop new treatments for radiation-induced intestinal injury. In this study, we investigated whether embryonic stem (ES) cells could be transplanted directly ...

The weatherloach, Misgurnus angulliacaudatus, is an intestinal air-breathing, freshwater fish that has the unique ability to excrete ammonia through gut volatilization when branchial and cutaneous routes are compromised during high environmental ammonia or air exposure. We hypothesized that transepithelial gut NH(4)(+) transport is facilitated by an apical Na(+)/H(+) (NH(4)(+)) exchanger (NHE) ...

Short bowel syndrome (SBS) occurs when, after surgery or congenitally, a patient is left with 200 cm of functional small intestine. Absorption is related to the amount of residual intestine; patients at greatest nutritional risk generally have a duodenostomy or a jejunoileal anastomosis with 35 cm of residual small intestine, jejunocolic or ileocolic anastomosis with 60 cm of residual small int...

Abstract To reduce potential trauma to the intestine caused by rigid shell while also optimising its progression efficiency, an elastomer coating was applied a self-propelled capsule robot for small-bowel endoscopy. The is periodically excited inner mass interacting with main body of in presence intestinal resistance. This work explored dynamic responses different coatings (i.e., elastic moduli...
