Podocytes are sensitive to fluid shear stress in vitro
American Journal of Physiology-Renal Physiology, 2006Podocytes are exposed to mechanical forces arising from glomerular capillary pressure and filtration. It has been shown that stretch affects podocyte biology in vitro and plays a significant role in the development of glomerulosclerosis in vivo.

Maturation of Adipocytes is Suppressed by Fluid Shear Stress
Cell Biochemistry and Biophysics, 2016Preadipocytes are mechano-responsive cells and their differentiation to adipocytes may be regulated by various types of physical stimulation. Understanding the mechanism of differentiation, which increases the number of adipocytes and lipid accumulation is important in the study of obesity-related diseases. In this study, we investigated the effects of

THE ELECTRORHEOLOGICAL FLUIDS WITH HIGH SHEAR STRESS
International Journal of Modern Physics B, 2005A series of high performance ER fluids newly manufactured in our laboratory are presented. The yield stress of those ER fluids can reach several tens of kPa, 100 kPa and even 200 kPa, respectively. For understanding the high shear stress effect a model is proposed base on the electric field induced molecular bounding effect.

Shear rheometry of fluids with a yield stress
Journal of Non-Newtonian Fluid Mechanics, 1987Abstract This work is concerned with the measurement of viscometric material functions of greases, which are fluids with a yield stress. Rheometers working under controlled stress or under kinematically controlled conditions have been used in plane and cone geometry.

Apparatus for Subjecting Living Cells to Fluid Shear Stress
Review of Scientific Instruments, 1982This apparatus subjects cultured cell specimens to controlled levels of fluid shear stress in vitro. The cone-plate geometry permits long term (≳7 days) investigation of the effects of external fluid forces on living cells.

Induction of Human Vascular Endothelial Stress Fibres by Fluid Shear Stress
Nature, 1984Endothelial cells of the arterial vascular system and the heart contain straight actin filament bundles, of which there are few, if any, in the venous endothelium. Since stress fibre-containing endothelial cells within the vascular system tend to be located at sites exposed to particularly high shear stress of blood flow, we have investigated, in an ...

Effect of Fluid Shear Stress on the Permeability of the Arterial Endothelium
Annals of Biomedical Engineering, 2002The localization of atherosclerotic lesions is due, in part, to regional variations in the permeability of arterial endothelium to macromolecules. In turn, endothelial permeability may be influenced by fluid shear stresses. The spatial variation in endothelial permeability is reviewed and evidence for shear stress dependence upon permeability is ...

The Fluid Shear Stress Distribution on the Membrane of Leukocytes in the Microcirculation
Journal of Biomechanical Engineering, 2003Recent in-vivo and in-vitro evidence indicates that fluid shear stress on the membrane of leukocytes has a powerful control over several aspects of their cell function. This evidence raises a question about the magnitude of the fluid shear stress on leukocytes in the circulation.

The kinetics of platelet aggregation induced by fluid-shearing stress
Microvascular Research, 1984The work herein examines in vitro the kinetics of platelet aggregation in response to the fluid-shearing stress imparted by a rotational viscometer. Aggregation is expressed through changes in particle size histograms and total particle count. Platelet aggregation commenced above 2000 sec-1 shear rate and was stable above 5000 sec-1.
