Determination of regional bone blood flow by means of fluorescent microspheres using an automated sample-processing procedure [PDF]
, 2003 The determination of regional blood flow utilizing fluorescent microspheres (FMs) is an established method for numerous organs. Recent progress, in particular the automation of sample processing, has further improved this method.

Pericyte-mediated regulation of capillary diameter: a component of neurovascular coupling in health and disease [PDF]
, 2010 Because regional blood flow increases in association with the increased metabolic demand generated by localised increases in neural activity, functional imaging researchers often assume that changes in blood flow are an accurate read-out of changes in ...

Journal of Cerebral Blood Flow and Metabolism, 2014 Diurnal rhythms have been observed in human behaviors as diverse as sleep, olfaction, and learning. Despite its potential impact, time of day is rarely considered when brain responses are studied by neuroimaging techniques.

Changes in regional blood volume and blood flow during static handgrip.
American Journal of Physiology. Heart and Circulatory Physiology, 2007 Increased blood pressure (BP) and heart rate during exercise characterizes the exercise pressor reflex. When evoked by static handgrip, mechanoreceptors and metaboreceptors produce regional changes in blood volume and blood flow, which are incompletely ...

Comparison of regional blood flow values measured by radioactive and fluorescent microspheres [PDF]
, 2002 Fluorescent microspheres (FM) have become an attractive alternative to radioactive microspheres (RM) for the measurement of regional blood flow (RBF). The aim of the present study was to investigate the comparability of both methods by measuring RBF with

PLoS ONE, 2019 IntroductionWhile extracorporeal membrane oxygenation (ECMO) is effective in preventing further hypoxemia and maintains blood flow in endotoxin-induced shock, ECMO alone does not reverse the hypotension.

Regional blood volume and peripheral blood flow in postural tachycardia syndrome.
American Journal of Physiology. Heart and Circulatory Physiology, 2004 Variants of postural tachycardia syndrome (POTS) are associated with increased ["high-flow" POTS (HFP)], decreased ["low-flow" POTS (LFP)], and normal ["normal-flow" POTS (NFP)] blood flow measured in the lower extremities while subjects were in the ...

The relationship between regional variations in blood flow and histology in a transplanted rat fibrosarcoma [PDF]
, 1990 The regional distribution of blood flow to the LBDS1 fibrosarcoma, transplanted into the subcutaneous site in rats, was investigated using the readily diffusible compound 14C-iodo-antipyrine (14C-IAP).
