introduction: it has been reported the alkaline response of pancreas to duodenal acidification is partly mediated through duodenal release of h2s, but till now the effect of duodenal acidification on gastric h2s release has not been investigated. therefore, the present study designed to evaluate the effects of duodenal acidification on gastric h2s release and level of mrna expression of cystath...

Direct evidence of prey choice in carnivorous dinosaurs is rare in the fossil record. The most celebrated example pertains to purported stomach contents in the carnivorous dinosaur Coelophysis bauri, which besides revealing prey choice, also points to cannibalistic behaviour as being commonplace (Colbert 1989, 1995). Here, we test this hypothesis by conducting the first comprehensive anatomical...

Not only seasonality but also taxonomic resolution of prey categories has been shown to affect diet studies. We analyzed the stomach contents of three sympatric species, Stellifer rastrifer, S. brasiliensis and S. stellifer, sampled monthly from August 2003 to October 2004 in Caraguatatuba Bay, southeastern Brazil. General characteristics and similarities among their diets were evaluated by con...

In anaesthetic practice it is occasionally necessary to make a rapid and accurate measurement of the pH of the gastric contents. A simple and convenient method is to use paper impregnated with a suitable indicator, the change in colour being read against a comparison chart provided with the paper. The purpose of this study was to compare the accuracy of interpretation of five different indicato...

Brucella spp. are facultative intracellular bacterial pathogens causing the zoonotic disease brucellosis. Here, we report the draft genome sequence of the Brucella melitensis strain from India designated Bm IND1, isolated from stomach contents of an aborted goat fetus.

Cod is the top piscivore predator in the Baltic Sea ecosystem. Based on stomach content data from 62 427 cod collected during 1977–1994 and food consumption rates, cannibalism in the Eastern and Western Baltic cod stocks has been quantified using multispecies virtual population analysis. In the Eastern Baltic stock, depending on model assumptions, an average of 25–38% of the 0-group and 11–17% ...

1. The adaptive radiation of fishes into benthic (littoral) and pelagic (lentic) morphs in post-glacial lakes has become an important model system for speciation. Although these systems are well studied, there is little evidence of the existence of morphs that have diverged to utilize resources in the remaining principal lake habitat, the profundal zone. 2. Here, we tested phenotype-environment...

Martin, M.D., F.R.S. Pp. xvi., 505. Edinburgh: Young J. Pentland. 1895. So many years have elapsed since an authoritative treatise on diseases of the stomach has appeared from British sources,, and so much advance has been made in recent years in our knowledge of the pathology of disorders of the stomach, that this book will be perused with great interest. The gain in knowledge of gastric affec...

Dietary analyses are important components of ecological studies. However, some methods of collecting organisms may expose them to exceptionally high densities of prey items, leading to inaccurate dietary assessments. These methods include the use of baited traps. We hypothesised that such a "trap effect" occurred during work on the diet of the rock lobster Jasus lalandii, because baited traps a...

BACKGROUND AND OBJECTIVES The current preoperative fasting guidelines allow fluid intake up to 2hours before surgery. The aim of this study was to evaluate the gastric volume of volunteers after an overnight fast and compare it with the gastric volume 2hours after ingestion of 200 and 500mL of isotonic solution, by means of ultrasound assessment. METHOD Eighty volunteers underwent gastric ult...
