The effects of osmotic stress on human platelets
Journal of Cellular Physiology, 1985AbstractThe effect of osmotic stress on human platelets was investigated at 0, 25, and 37°C. The osmolality of the suspending plasma was decreased by adding water or increased by adding sodium chloride or sucrose. After 5 min, isotonicity was restored by dilution with an excess of isotonic phosphate‐buffered saline.

Osmotic stress as a mechanism of freezing injury
Cryobiology, 1971Abstract When red cells are suspended in solutions of nonpenetrating solutes of osmolality in excess of 1300 mosm, changes in membrane permeability are seen: there is an influx of extracellular solute, cell volume increases, and the cells will hemolyze on return to isotonic suspension. Furthermore, if cells suspended in such a solution are exposed to

Abstract When thinking of biophysical and biochemical processes, we are used to consider the concentrations (or activities) of the ions and other active ingredients dissolved in the water of the cytosol and of the extracellular fluids. Yet water itself has a concentration (and activity), which is in a reciprocal relationship to the sum ...

Erythrocytes under osmotic stress – modeling considerations
Progress in Biophysics and Molecular Biology, 2015Various modeling approaches have been applied to describe structural changes of the erythrocyte constituents under osmotic stress. The constituents: (1) the lipid bilayer, (2) the actin-spectrin cortex, (3) the trans-membrane protein band 3, (4) the intracellular hemoglobin contribute to the relaxation phenomenon. Cells response includes the successive

It has been proposed that drought by restricting carbon assimilation by CO2 depletion (stomatal closure) or by biochemical alterations in the chloroplast could predispose the photosynthetic apparatus to photoinhibition. However experimental data have shown contradictory results depending upon the considered species : in Nerium oleander (1) and in low ...

Neuronal Adaptations to Osmotic Stress
1985In higher invertebrates and vertebrate animals integrated neural function is critically dependent on a stable chemical environment for the nerve cells. In fully marine, invertebrate osmoconformers this stability is provided by the environment itself, the remarkable constancy of which has enabled the evolution of such complex nervous systems as those of
