Osmotic Stress and the Brain

2004
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 ...

Osmotic stress as a mechanism of freezing injury

Cryobiology, 1971
Abstract 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

Silicon transcriptionally regulates sulfur and ABA metabolism and delays leaf senescence in barley under combined sulfur deficiency and osmotic stress

Environmental and Experimental Botany, 2018
Several studies have revealed that both sulfur (S) and silicon (Si) nutrition play a pivotal role in alleviating drought stress tolerance in plants. Additionally, Si application has also been reported to mitigate plant nutrient deficiency.

Erythrocytes under osmotic stress – modeling considerations

Progress in Biophysics and Molecular Biology, 2015
Various 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

Photosynthesis under Osmotic Stress. A Possible Cause of the Osmotic Stress Induced Susceptibility to Photoinhibition

1987
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

1985
In 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
