Glucose Does Not Facilitate the Absorption of Sorbitol Perfused In Situ in the Human Small Intestine , [PDF]

The Journal of Nutrition, 1997
Sorbitol is better absorbed in the small intestine when ingested concomitantly with glucose. The aim of this study was to test in situ the effect of glucose on the absorption of sorbitol in the human small intestine, using the perfusion technique. The sorbitol absorption of three test solutions, perfused in a random order, was measured in a 30-cm ...

Perfusion assessment via local remote photoplethysmography (rPPG) [PDF]

2022 IEEE/CVF Conference on Computer Vision and Pattern Recognition Workshops (CVPRW), 2022
This paper presents an approach to assess the perfusion of visible human tissue from RGB video files. We propose metrics derived from remote photoplethysmography (rPPG) signals to detect whether a tissue is adequately supplied with blood. The perfusion analysis is done in three different scales, offering a flexible approach for different applications ...

Intestinal blood flow in patients with chronic heart failure: A link with bacterial growth, gastrointestinal symptoms, and cachexia [PDF]

, 2014
Background: Blood flow in the intestinal arteries is reduced in patients with stable heart failure (HF) and relates to gastrointestinal (GI) symptoms and cardiac cachexia.

The Effects of Cetirizine on P-glycoprotein Expression and Function In vitro and In situ [PDF]

Advanced Pharmaceutical Bulletin, 2016
Purpose: P-glycoprotein (P-gp) plays a major role in oral absorption of drugs. Induction or inhibition of P-gp by drugs contributes to variability of its transport activity and often results in clinically relevant drug-drug interactions.

Reduction in jejunal fluid absorption in vivo through distension and cholinergic stimulation not attributable to enterocyte secretion [PDF]

, 2018
Jejunal fluid absorption in vivo was reduced by distension and by hydrostatic pressure and further declined on adding E. coli STa enterotoxin but no net fluid secretion was detected.

An investigation into the relationship between small intestinal fluid secretion and systemic arterial blood pressure in the anesthetized rat [PDF]

, 2015
In the absence of an ability to absorb fluid by cellular uptake mechanisms, fluid movement in vivo from the perfused rat intestine is absorptive when the diastolic blood pressure is normal or very low but is secretory when blood pressure falls below ...
