Effects of posture on the physiology of gastric emptying: a magnetic resonance imaging study


Steingoetter, Andreas; Fox, Mark; Treier, Reto; Weishaupt, Dominik; Marincek, Borut; Boesiger, Peter; Fried, Michael; Schwizer, Werner (2006). Effects of posture on the physiology of gastric emptying: a magnetic resonance imaging study. Scandinavian Journal of Gastroenterology, 41(10):1155-1164.

Abstract

The stomach maintains the rate of gastric emptying despite radical changes in body position and intragastric distribution of gastric contents. In SP, hydrostatic pressure (modulated by gastric tone) dictates the gastric emptying. In UDP, gastric emptying also appears to be mediated by continuous adaptation of gastric tone. These findings provide support for the hypothesis that the mechanism of gastric emptying resembles a "pressure pump" rather than a "peristaltic pump".

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
