Bistability of cell adhesion in shear flow.
Cell adhesion plays a central role in multicellular organisms helping to maintain their integrity and homeostasis. This complex process involves many different types of adhesion proteins, and synergetic behavior of these proteins during cell adhesion is frequently observed in experiments. A well-known example is the cooperation of rolling and stationary adhesion proteins during the leukocytes e...
متن کاملIncrease in erythrocyte disaggregation shear stress in hypertension.
The aggregation and disaggregation behaviors of red blood cells were investigated in 17 normotensive and 21 hypertensive subjects with a laser reflectometry technique, and simultaneous measurements were taken of blood viscosity with a coaxial viscometer. Increased red blood cell aggregation (26%, p less than 0.001) and disaggregation shear rate (20%, p less than 0.01) and shear stress (18%, p l...
متن کاملErythrocyte disaggregation shear stress, sialic acid, and cell aging in humans.
Erythrocyte aggregation, which plays an important role in the physiological behavior of blood fluidity, was found to be enhanced in hypertension and hypercholesterolemia. While the role of macromolecule bridging force has been widely described, cellular factors related to membrane sialic acid content, which might contribute to the negative charge of cell surface causing the repulsion of erythro...
متن کاملModeling the behavior of confined colloidal particles under shear flow.
We investigate the behavior of colloidal suspensions with different volume fractions confined between parallel walls under a range of steady shears. We model the particles using molecular dynamics (MD) with full hydrodynamic interactions implemented through the use of a lattice-Boltzmann (LB) fluid. A quasi-2d ordering occurs in systems characterized by a coexistence of coupled layers with diff...
متن کاملRheology of concentrated xanthan gum solutions: Oscillatory shear flow behavior
Using a strain-controlled rheometer, the dynamic viscoelastic properties of aqueous xanthan gum solutions with different concentrations were measured over a wide range of strain amplitudes and then the linear viscoelastic behavior in small amplitude oscillatory shear flow fields was investigated over a broad range of angular frequencies. In this article, both the strain amplitude and concentrat...
