Vascular access dysfunction is one of the main causes of morbidity and hospitalization in
hemodialysis patients. This major clinical problem points out the need for prediction of …

OBJECTIVE: Wall shear stress (WSS) is an important parameter with links to vascular (dys)
function. Difficult to measure directly, WSS is often inferred from maximum spectral Doppler …

Background Pulsatile flow protects vital organ function and improves microcirculatory
perfusion during extracorporeal membrane oxygenation (ECMO). Studies revealed that …

A common clinical practice during single-point Doppler analysis is to measure the centerline
maximum velocity and to recover the time-averaged flow rate by exploiting an assumption …

Given evidence that fully developed axisymmetric flow may be the exception rather than the
rule, even in nominally straight arteries, maximum velocity (Vmax) can lie outside the …

To estimate arterial stiffness, different methods based either on distensibility, pulse wave
velocity or a pressure-velocity loop, have been proposed. These methods can be employed …

Wall shear stress (WSS) plays a key role in maintaining glycocalyx function, gene
expression, and structure. Experimental studies have discussed the relationship between …

A significant number of arteriovenous fistulas (AVFs) fail to maturate for dialysis. Although
interventions promote maturation, functional primary patency loss is higher for AVFs with …

Purpose Continuous positive airway pressure (CPAP) is the gold standard treatment for
obstructive sleep apnea. However, the physiologic impact of CPAP on cerebral blood flow …

Abstract A Random Positioning Machine (RPM) is a device used to study the role of gravity
on biological systems. This is accomplished through continuous reorientation of the sample …
