Notch signaling and fluid shear stress in regulating osteogenic differentiation
Osteoporosis is a common bone and metabolic disease that is characterized by bone density loss and microstructural degeneration. Human bone marrow-derived mesenchymal stem cells (hMSCs) are multipotent progenitor cells with the potential to differentiate

Fluid Shear Stress Sensing by the Endothelial Layer [PDF]
Blood flow produces mechanical frictional forces, parallel to the blood flow exerted on the endothelial wall of the vessel, the so-called wall shear stress (WSS). WSS sensing is associated with several vascular pathologies, but it is first a physiological phenomenon.

Fluid shear stress enhances dendritic cell activation. [PDF]
Ex vivo activation of dendritic cells (DCs) has been widely explored for targeted therapies, although these treatments remain expensive. Reducing treatment costs while enhancing cell activation could help to make immunotherapies more accessible. Cells can be activated by both internal and external forces including fluid shear stress (FSS).

Shear-enhanced yield stress in electrorheological fluids [PDF]
We report the enhancement of yield stress in electrorheological (ER) fluids by a shear-annealing method, using creep-recovery (CR) cycles under an external electric field. The enhancement depends on the duration and the strength of the applied shear stress, as well as on the number of the CR cycles.

The Effect of Wall Shear Stress and Viscous Heating on Nanoscale Flow [PDF]
The effect of wall shear stress and viscous heating on nano scale flow properties and boundary conditions is presented. Molecular dynamics (MD) simulations is implemented to handle nano scale force-driven Poiseuille flow bounded by two parallel planner ...

AimsCoronary artery stents have profound effects on arterial function by altering fluid flow mass transport and wall shear stress. We developed a new integrated methodology to analyse the effects of stents on mass transport and shear stress to inform the

Shear-stress-controlled dynamics of nematic complex fluids [PDF]
Based on a mesoscopic theory we investigate the non-equilibrium dynamics of a sheared nematic liquid, with the control parameter being the shear stress $σ_{\mathrm{xy}}$ (rather than the usual shear rate, $\dotγ$). To this end we supplement the equations of motion for the orientational order parameters by an equation for $\dotγ$, which then becomes ...

Manipulating Arterial Fluid-shear Stress and Arteriogenesis in the Brain [PDF]
Occlusions of the brain arteries remain life-threatening diseases and are associated with devastating morbidity. The basic, physiological and spontaneous reactions of the organism to vascular occlusion are to develop adaptative collateral circulation(s) outside the ischemic region, which can potentially replace the feeding capacity of the larger ...

Fluid Shear Stress Enhances the Phagocytic Response of Astrocytes [PDF]
Astrocytes respond to brain injury at a cellular level by the process of reactive astrogliosis, and are able to adjust their response according to the severity of the insult. Included in the reactive response is the process of phagocytosis, where astrocytes clean up surrounding cellular debris from damaged cells.
