potassium channels allow potassium flux and are essential for the generation of electric current acrossexcitable membranes. potassium channels are also the targets of various intracellular controlmechanisms; such that the suboptimal regulation of channel function might be related to pathologicalconditions. realistic studies of ion current in biologic channels present a major challenge for compu...

in this article, preparation of polypyrrole and its nanocomposites as adsorbents werediscussed and the capability of separation of copper ions from aqueous solution were studied.polypyrrole was prepared by chemical oxidative polymerization method of pyrrole usingfecl3 as an oxidant. the removal of cu (ii) was investigated using ppy, ppy/tio2 andppy/tio2/dhsna nanocomposites. the products were i...

the present work is carried out to study the antioxidant potential of ethanolic extract of alstonia scholaris linn. ( apocynaceae ) using various in vitro tests including 1,1-diphenyl-2-picryl-hydrazil (dpph . ) free radical scavenging, metal ion chelating, hydrogen peroxide scavenging, superoxide anion radical scavenging, and ferric thiocyanate reducing ability.   ethanolic extract of alstonia...
