Effects of anesthesia on cerebral blood flow, metabolism, and neuroprotection
Journal of Cerebral Blood Flow and Metabolism, 2018 Administration of anesthetic agents fundamentally shifts the responsibility for maintenance of homeostasis from the patient and their intrinsic physiological regulatory mechanisms to the anesthesiologist.

Renal pericytes: regulators of medullary blood flow [PDF]
, 2012 Regulation of medullary blood flow (MBF) is essential in maintaining normal kidney function. Blood flow to the medulla is supplied by the descending vasa recta (DVR), which arise from the efferent arterioles of juxtamedullary glomeruli.

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 ...

Capillary K+-sensing initiates retrograde hyperpolarization to locally increase cerebral blood flow
Nature Neuroscience, 2017 Blood flow into the brain is dynamically regulated to satisfy the changing metabolic requirements of neurons, but how this is accomplished has remained unclear. Here we demonstrate a central role for capillary endothelial cells in sensing neural activity

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.

Rheology of human blood plasma: Viscoelastic versus Newtonian behavior
, 2013 We investigate the rheological characteristics of human blood plasma in shear and elongational flows. While we can confirm a Newtonian behavior in shear flow within experimental resolution, we find a viscoelastic behavior of blood plasma in the pure ...

Pulsatile microvascular blood flow imaging by short-time Fourier transform analysis of ultrafast laser holographic interferometry [PDF]
, 2015 We report on wide-field imaging of pulsatile microvascular blood flow in the exposed cerebral cortex of a mouse by holographic interferometry. We recorded interferograms of laser light backscattered by the tissue, beating against an off-axis reference ...
