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

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.

Light-Absorbing Properties and Osmolarity of Indocyanine-Green Depending on Concentration and Solvent Medium [PDF]
Investigative Opthalmology & Visual Science, 2003 To evaluate the absorption spectrum and osmolarity of three currently used indocyanine green (ICG) products at different concentrations and with different solvent media.The absorption spectrum and osmolarity of three different ICG products (Pulsion, Munich, Germany; Akorn, Buffalo Grove, IL; and Laboratoires SERB, Paris, France) were analyzed. Each ICG

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 [PDF]
Journal of NanobiotechnologyExtracellular 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-

Sucrose Concentration and Osmolarity as Factors Affecting in Vitro Wax Accumulation in Jojoba Embryos [PDF]
HortScience, 1986 Abstract Immature zygotic embryos of jojoba (Simmondsia chinensis Link) (average 5.6 mm in length about 2 months after pollination) were cultured on semisolid or in liquid basal medium for 8 weeks. On semisolid medium supplemented with 3%, 9%, or 21% sucrose, zygotic embryos attained 54, 125, or 48 mg dry weight with 11, 42, or 19 mg wax esters ...

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

Hyperosmolarity in children with hyperammonemia: a risk of brain herniation at the start of renal replacement therapy [PDF]
Frontiers in PediatricsPurposeRenal replacement therapy (RRT) is used in hyperammonemia to reduce the concentration of ammonia in the blood. In the case of plasma hyperosmolarity, RRT can also rapidly decrease plasma osmolarity, which may increase cerebral edema in these ...
