background: we investigated the effects of cigarette smoking in non-per os (npo) period on volume and ph of gastric contents in smoker male patients. methods: in a prospective cohort study, 86 male smoker patients undergoing elective non-abdominal surgery under general anesthesia, were surveyed. they were npo for at least 8-12 hrs. prior to surgery without direction to smoking. then they were d...
objective: gut–brain axis (gba) is very important in creation and modulation of gastrointestinal problems. aloe vera gel has gastroprotective properties. the purpose of this study was to evaluate the effect of aqueous extract of aloe vera leaves on the gastric acid secretion and brain and intestinal water content following acetic acid gastric ulcer induction. materials and methods: gastric ulce...
Northern fulmars as biological monitors of trends of plastic pollution in the eastern North Pacific.
Marine plastic debris is a global issue, which highlights the need for internationally standardized methods of monitoring plastic pollution. The stomach contents of beached northern fulmar (Fulmarus glacialis) have proven a cost-effective biomonitor in Europe. However, recent information on northern fulmar plastic ingestion is lacking in the North Pacific. We quantified the stomach contents of ...
We present a new method of measuring the food intake in cormorants based on stomach temperature recordings. Stomach temperature loggers were deployed both in captive and in free-living birds. We examine the accuracy of this method and compare it with the standard methods of evaluating food intake by pellet or stomach content analysis.
Short-term (h) and long-term (days) individual variability and the effects of momentary change in feeding intensity on digestion time were studied in the scyphomedusa Aurelia aurita as a basis for developing a method to experimentally measure the digestion rate with a high precision. Ten individual medusae showed only small, non-significant differences in average digestion time (range, 2.1-2.5 ...
Objective: Gut–brain axis (GBA) is very important in creation and modulation of gastrointestinal problems. Aloe vera gel has gastroprotective properties. The purpose of this study was to evaluate the effect of aqueous extract of Aloe vera leaves on the gastric acid secretion and brain and intestinal water content following acetic acid gastric ulcer induction. Materials and Methods: Gastric ulce...
We analyzed the stomach contents of 116 individuals belonging to seven fishes species in order to investigate seasonal changes in feeding strategy and how trophic interactions between species affect community structure in an Atlantic rainforest stream in Southeastern Brazil. Oligosarcus hepsetus and Pimelodus sp. consumed fewer items during the winter. Phalloceros caudimaculatus switched feedin...
Diets estimated from different proxies such as stable isotopes, stomach contents, and dental microwear often disagree, leading to nominally well-supported but greatly differing estimates of diet for both extinct and extant species that complicate our understanding of ecology. We show that these perceived incongruences can be caused by proxies recording diet over vastly different timescales. Fie...
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 cys...
