Prehypertensive Blood Pressures and Regional Cerebral Blood Flow Independently Relate to Cognitive Performance in Midlife [PDF]

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
Background High blood pressure is thought to contribute to dementia in late life, but our understanding of the relationship between individual differences in blood pressure (BP) and cognitive functioning is incomplete.

Phosphomimetic modulation of eNOS improves myocardial reperfusion and mimics cardiac postconditioning in mice. [PDF]

open access: yesPLoS ONE, 2014
Myocardial infarction resulting from ischemia-reperfusion injury can be reduced by cardiac postconditioning, in which blood flow is restored intermittently prior to full reperfusion.

Altered cerebral hemodyamics and cortical thinning in asymptomatic carotid artery stenosis. [PDF]

open access: yesPLoS ONE, 2017
Cortical thinning is a potentially important biomarker, but the pathophysiology in cerebrovascular disease is unknown. We investigated the association between regional cortical blood flow and regional cortical thickness in patients with asymptomatic ...

Effects of Arterial Carbon Dioxide Tension on Cerebral and Somatic Regional Tissue Oxygenation and Blood Flow in Neonates After the Norwood Procedure With Deep Hypothermic Cardiopulmonary Bypass

open access: yesFrontiers in Pediatrics, 2022
Neonates undergoing the Norwood procedure for hypoplastic left heart syndrome are at higher risk of impaired systemic oxygen delivery with resultant brain, kidney, and intestinal ischemic injury, shock, and death.

Determination of regional bone blood flow by means of fluorescent microspheres using an automated sample-processing procedure [PDF]

open access: yes, 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.

Acute Blood Loss: Regional Blood Flow and Microcirculation (Review, Part II)

open access: yesОбщая реаниматология, 2017
It was shown in the first part of the review that the alterations of systemic hemodynamics and microcirculation in acute blood loss led to the development of metabolic disorders and cell damage.

Methylphenidate’s Effect on Cerebral Blood Flow in Patients with Narcolepsy [PDF]

open access: yesSleep Medicine Research, 2010
We performed 99mTc-ethyl cysteinate dimer brain single-photon emission computed tomography before and after administering methyl-phenidate, for four weeks, to narcolepsy patients with cataplexy.

Pericyte-mediated regulation of capillary diameter: a component of neurovascular coupling in health and disease [PDF]

open access: yes, 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 ...

Acute Blood Loss: Regional Blood Flow and Microcirculation (Review, Part I)

open access: yesОбщая реаниматология, 2016
The first part of the review highlights the data on the structural and functional organization of the microvas culature; regulation of vascular tone including local (metabolic and myogenic mechanisms, role of endothelium and red blood cells) and systemic
