Platelets and shear stress.
C LINICAL BLEEDING or thrombosis results from a disturbance in the balance between a complex network of procoagulant and anticoagulant factors. This network involves three primary interactions, first described by the eminent pathologist Rudolph Virchow during the previous century, between blood (soluble and cellular constituents), the blood vessel (including fixed and dynamic responses), and bl...
متن کاملShear Stress and Atherosclerosis
Hemodynamic shear stress, the frictional force acting on vascular endothelial cells, is crucial for endothelial homeostasis under normal physiological conditions. When discussing blood flow effects on various forms of endothelial (dys)function, one considers two flow patterns: steady laminar flow and disturbed flow because endothelial cells respond differently to these flow types both in vivo a...
متن کاملBoundary Shear Stress in a Trapezoidal Channel
This paper focuses on a hydraulic radius separation approach used to calculate the boundary shear stress in terms of bed and wall shear stress proposed in a trapezoidal channel. The average bed and sidewall shear stress in smooth trapezoidal open channels are derived after using Guo & Julien (2005) early equations taking a part of an investigation to cover both rectangular and trapezoidal chann...
متن کاملShear stress relaxation in liquids.
We show that at high densities, as the system size decreases, liquid becomes able to permanently sustain increasing internal shear stress after a constant deformation, although the other characteristic liquid properties, such as the pair distribution function and diffusion coefficient do not change under strain. The system size necessary for observation of this effect increases with the decreas...
متن کاملIn vivo shear stress response.
EC (endothelial cell) responses to shear stress generated by vascular perfusion play an important role in circulatory homoeostasis, whereas abnormal responses are implicated in vascular diseases such as hypertension and atherosclerosis. ECs subjected to high shear stress in vitro alter their morphology, function and gene expression. The molecular basis for mechanotransduction of a shear stress ...
