In recent years, many groups of clinical scientists have become interested in measuring transmembrane ion fluxes of various kinds in patients with different diseases. The ion fluxes of interest have included the ouabainsensitive Na+/K+ pump, the loop-diuretic-sensitive Na+/ K+ co-transport system, the phloretin-sensitive Na+/Na+ (or Na+/Li+ ) countertransport system, and the amiloridesensitive ...

This paper is mainly focusing on the determination of mean molal activity coefficient of HCl in aqueous acidic medium. The present investigations have been carried out to determine the activity coefficients of hydrochloric acid in 2-propanol water mixture solutions under various conditions to study the ion solvent interactions in different temperatures. The standard molar potential Em0 of the c...

1. Acetylcholine produced end-plate current (e.p.c.) noise is shown to be the results of statistical fluctuations in the ionic conductance of voltage clamped end-plates of Rana pipiens.2. These e.p.c. fluctuations are characterized by their e.p.c. spectra which conform to a relation predicted from a simple model of end-plate channel gating behaviour.3. The rate constant of channel closing alpha...

This paper reports the evaluation of adsorbing Cr (VI) ions on sorbent prepared from chitosan (CHT), a versatile derivative of chitin, and dodecyl amine modified locally available kaolinite clay (Bijoypur clay) (MC) that has excellent mechanical properties and great resistance to chemical and biological attack. The effect of the initial metal ion concentration, solution pH, contact time, and ad...

the hydrolysis of sodium borohydride as a source of hydrogen gas is studied at different mole ratios of h+ to nabh4. the sulfonated porous carbon (spc) is used as a source of hydrogen ion and catalyst. it is found that the sulfonated porous carbon exhibits high activity for the hydrolysis of nabh4 to generate hydrogen gas at room temperature in comparison to amberlyst-15 and nafion-nr50. the ki...
