in this work attempts were made to evaluate k+-sds and hydrocolloid polymer-sds interactions in flocculation of megestrol acetate dispersions to enhancetheir stability as a part of suspension formulation. different dispersions of micronized megestrol acetate and sds were prepared. kcl and kh2po4 and their corresponding sodium salts were added to the dispersions and the preparations were evaluat...

We study the surface tension of electrolyte solutions at the air/water and oil/water interfaces. Employing field-theoretical methods and considering short-range interactions of anions with the surface, we expand the Helmholtz free energy to first order in a loop expansion and calculate the excess surface tension. Our approach is self-consistent and yields an analytical prediction that reunites ...

The influence of varying the ionic strength of the bathing solution on the contraction of chemically skinned frog atrial muscle fibers was studied. The rate of tension development activated by calcium slows as the ionic strength is elevated. The size of caffeine contracture, however, was larger in the fiber preloaded with calcium at a higher ionic strength. There was a decrease in the maintaine...

Investigation of factors that modulate amyloid formation of proteins is important to understand and mitigate amyloid-related diseases. To understand the role of electrostatic interactions and the effect of ionic cosolutes, especially anions, on amyloid formation, we have investigated the effect of salts such as NaCl, NaI, NaClO(4), and Na(2)SO(4) on the amyloid fibril growth of beta(2)-microglo...
