Abnormal Myocardial Blood Flow Reserve Observed in Cardiac Amyloidosis [PDF]

open access: yes, 2016
We performed real-time myocardial contrast echocardiography on a patient with cardiac amyloidosis and previous normal coronary angiography presenting with atypical chest pain to assess myocardial blood flow reserve (MBFR).

Fractal Rigidity in Migraine [PDF]

open access: yes, 2003
We study the middle cerebral artery blood flow velocity (MCAfv) in humans using transcranial Doppler ultrasonography (TCD). Scaling properties of time series of the axial flow velocity averaged over a cardiac beat interval may be characterized by two ...

Microstructured Thin Film Nitinol for a Neurovascular Flow-Diverter [PDF]

open access: yes, 2016
A cerebral aneurysm occurs as a result of a weakened blood vessel, which allows blood to flow into a sac or a ballooned section. Recent advancement shows that a new device, ‘flow-diverter’, can divert blood flow away from the aneurysm sac.

Renal pericytes: regulators of medullary blood flow [PDF]

open access: yes, 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]

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 ...

Pulsatile spiral blood flow through arterial stenosis [PDF]

open access: yes, 2014
Pulsatile spiral blood flow in a modelled three-dimensional arterial stenosis, with a 75% cross-sectional area reduction, is investigated by using numerical fluid dynamics.

Analyzing the involvement of diverse cell death-related genes in diffuse large B-cell lymphoma using bioinformatics techniques

open access: yesHeliyon
Diffuse large B-cell lymphoma (DLBCL) stands as the most prevalent subtype of non-Hodgkin's lymphoma and exhibits significant heterogeneity. Various forms of programmed cell death (PCD) have been established to have close associations with tumor onset ...

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.
