K-Cl cotransport in LK sheep erythrocytes is activated by osmotic swelling and inhibited by shrinkage. The mechanism by which changes in cell volume are transduced into changes in transport was investigated by measuring time courses of changes in transport after osmotic challenges in cells with normal and reduced Mg concentrations. When cells of normal volume and normal Mg are swollen, there is...

hydrogel nanocomposites based on alginate polysaccharide were prepared by graft copolymerization of acrylamide and itaconic acid in the presence of carbon nanotube, using methylene bisacrylamide and ammonium persulfate as crosslinker and initiator, respectively. the synthesized samples were characterized by infrared spectroscopy, thermogravimetric analysis and scanning electron microscopy. the ...

in order to determine outcome of pregnancy with lui in patients with unexplained recurrent miscarriage whose husbands have low hypo-osmotic swelling test scores, a prospective clinical intervention was performed at a university referral clinic of recurrent abortion. out of 56 patients whose husbands had abnormal hypo-osmotic swelling tests, 43 patients underwent lui, from which only 14 patients...

Swelling of metals under irradiation is largely studied in the nuclear industry for its impact on safe and efficient operation reactors. However, case aluminum alloys remains poorly documented as they are exclusively used research reactors which operate at lower temperatures than power plants. Void swelling alloys, results from cavities induced by fast neutron flux reactor, measurable only high...

Mitochondrial volume homeostasis is a housekeeping cellular function essential for maintaining the structural integrity of the organelle. Changes in mitochondrial volume have been associated with a wide range of important biological functions and pathologies. Mitochondrial matrix volume is controlled by osmotic balance between cytosol and mitochondria. Any dysbalance in the fluxes of the main i...

The rapid hemolysis by fresh guinea pig serum known to occur with neuraminidase-treated sheep red cells has been investigated with respect to the immunological and physiological properties of the lytic process. The following observations were made: (a) The susceptibility to hemolysis is directly proportional to the amounts of neuraminic acid enzymatically released from the cell surface. Complem...

Two sets of microemulsions, cyclohexane- and water-rich ones, were prepared with the following n-alkanols as cosurfactants: n-propanol, n-butanol, n-pentanol, and n-hexanol. The results showed the influence of the alkyl chain length of the n-alkanol on the permselectivity properties of the pervaporation technique in the breakdown of the microemulsions. The variations of the total flux rate J an...

I N T R O D U C T I O N Red blood cells of several species exhibit a K+-CI cotransport flux that can be activated by either cell swelling or chemical modification with N-ethylmaleimide (NEM) (see Lauf, 1983a, 1984, 1985; Brugnara et al., 1985, 1989; McManus et al., Address reprint requests to Dr. Michael L. Jennings, Department of Physiology and Biophysics, University of Texas Medical Branch, G...

Our general goal is to study chemo-mechanical problems at various length scales by means of a fully-integrated approach in terms co-design variational formulations and tailored parallel solvers. Based on prior experience electro-magneto-mechanics [1], we know that the advantages disadvantages different settings for such coupled always multifaceted. Theoretical characteristics, physical interpre...
