... physicochemical parameters in the luminal fluids in the stomach, anterior, mid and posterior intestine of fasted trout and those fed recently with commercial trout pellets. It should be noted that fish referred to as ‘fed’ in the literature generally receive commercial pellets that do not reflect a natural food...

... guinea pig rat mouse gastrointestinal mucus carbonic anhydrase colon stomach In a previous study, we used a mass spectrometric technique to measure intracellular CA activity and membrane bicarbonate permeability of intact guinea pig colonic epithelium ( Böllert et al., 1997 ). In addition...

...H. Onken; S. B. Moffett; D. F. Moffett SUMMARY The lumen-negative transepithelial voltage ( V te ) of the isolated and perfused anterior stomach of mosquito larvae ( Aedes aegypti ) was studied with a `semi-open' preparation in which one end of the gut was ligated onto a perfusion pipette...

...Stephen M. Secor SUMMARY The large intact prey ingested by Burmese pythons require considerable processing by the stomach before passage into the small intestine. To investigate the function and cost of gastric digestion and its contribution to postprandial metabolic response for the Burmese python...

... and the viscera. Red muscle, white muscle and stomach temperatures were measured in juvenile (5–13.6 kg) makos swimming steadily in a water tunnel and exposed to stepwise square-wave changes in ambient temperature ( T a ) to estimate the rates of heat transfer and to determine their capacity for the activity...

...Masatomo Maeda; Kentaro Kubo; Tsuyoshi Nishi; Masamitsu Futai ABSTRACT The gastric H + /K + -ATPase is a P-type ATPase that is specifically expressed in gastric parietal cells and is responsible for acid secretion into the stomach. We have found one or more gastric mucosal nuclear proteins...

... into the gland lumen at a low rate and, thereby, keeping the resting luminal [HCO 3 − ] low. Indeed, the stomach does secrete acid between meals although in some subjects the pH of the stomach lumen is not low enough to eliminate HCO 3 − . Moreover, it is not known whether all glands continuously secreted low...
