Serum Osmolarity and Vasopressin Concentration in Acute Heart Failure—Influence on Clinical Course and Outcome [PDF]

Biomedicines, 2022
Neurohormone activation plays an important role in Acute Heart Failure (AHF) pathophysiology. Serum osmolarity can affect this activation causing vasopressin excretion. The role of serum osmolarity and vasopressin concentration and its interaction remain still unexplored in AHF.

Osmolar Concentration and Fixation of Mycoplasmas [PDF]

Journal of Bacteriology, 1972
Broth cultures of Acholeplasma laidlawii were fixed with various concentrations of cacodylate-buffered glutaraldehyde. The shape and ultrastructure of the organisms varied with the osmolar concentration of the fixative. When the fixation mixture was hypertonic to the culture medium, ultrathin sections suggested that

The potential effect of low cell osmolarity on cell function through decreased concentration of enzyme substrates [PDF]

Journal of Experimental Botany, 2018
Some freshwater algae have lower (180 osmol m-3). Low osmolarities are related to the presence of flagella and the low energy cost of active water efflux following downhill water influx unconstrained by cell walls covering the plasmalemma, and the low resource cost of cell wall synthesis with the same mechanical degree of safety. One consequence of low

Relationship between extracellular osmolarity, NaCl concentration and cell volume in rat glioma cells

General Physiology and Biophysics, 2011
The cell volume, which controls numerous cellular functions, is theoretically linearly related with the inverse osmolarity. However, deviations from this law have often been observed. In order to clarify the origin of these deviations we electronically measured the mean cell volume of rat glioma cells under three different experimental conditions ...

Optimization of macroelement concentrations, pH and osmolarity for triacylglycerol accumulation in Rhodococcus opacus strain PD630 [PDF]

AMB Express, 2013
Abstract The refinement of biodiesel or renewable diesel from bacterial lipids has a great potential to make a contribution for energy production in the future. This study provides new data concerning suitable nutrient concentrations for cultivation of the Gram-positive Rhodococcus opacus PD630, which is able to accumulate large amounts of ...

Ion osmolarity-driven sequential concentration-enrichment for the scale-up isolation of extracellular vesicles

Journal of Nanobiotechnology
Extracellular vesicles (EVs) carry a variety of bioactive molecules and are becoming a promising alternative to cell therapy. Scale-up EV isolation is necessary for their functional studies and biological applications, while the traditional methods are challenged by low throughput, low yield, and potential damage. Herein, we developed an ion osmolarity-

Influence of dietary protein content and source on fecal quality, electrolyte concentrations, and osmolarity, and digestibility in dogs differing in body size1 [PDF]

Journal of Animal Science, 2009
When fed the same diet, large-breed dogs tend to produce feces of poorer quality compared with small-breed dogs. Moreover, German shepherds, although having a BW similar to Giant Schnauzers, are particularly prone to digestive intolerance, producing feces of poor consistency and increased moisture.

Effects of Cholesterol Concentration and Osmolarity on the Fluidity and Membrane Tension of Free-standing Black Lipid Membranes

Analytical Sciences, 2018
Although the mechanical properties and compositions of lipid bilayer membranes can change upon deformation, the fundamental relations between the composition, membrane tension and fluidity of membranes with little curvature have not yet been studied. In the current study, the membrane tension and the diffusion coefficients of free-standing black lipid ...
