The gastrointestinal system anatomically is posi-tioned to perform two distinct functions: to digest and absorb ingested nutrients and to sustain barrier func-tion to prevent transepithelial …

In each of these conditions, poor tissue perfusion may result in ischemic necrosis of the intestine. With gene expression techniques it may be possible to trace the ontogeny of systems …

2015年7月1日 · The gastrointestinal (GI) circulation receives a large fraction of cardiac output and this increases following ingestion of a meal. While blood flow regulation is not the intense …

In the case of physiologic stresses, reperfusion of the gastrointestinal tract occurs with cessation of the stress, while therapeutic interventions (e.g., vasodilators) are used to reperfuse the …

Autoregulation is present also in hypertensive individuals, but the lower pressure limit is higher and the curve is shifted to the right compared with healthy subjects.

This review considers critically the striking clinical data and basic physiological investigations that support a key role for gastrointestinal hypoperfusion in initiating and/or perpetuating critical …

GI dysfunction refers broadly to functional impairment of the GI tract that may include disturbances in motility and/or absorption, breaches in mucosal integrity, changes in the …
