A novel zinc oxide - agar nanocomposite was successfully synthesized using zinc chloride as a precursor. The nanocomposite was prepared using a domestic microwave oven. The prepared nanocomposites have been characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM) and UV- visible spectroscopy. The crystalline properties...

the use of natural compounds to control plant pathogens lead to reduction in using fungicides. chitosan with duble effects, control pathogenic microorganisms and activate inducing defence responses, has been shown to be a reliable nontoxic material in the plant-pathogen interaction. the aim of this research was to consider the effects of chitosan and calcium chloride on decay and quality attrib...

Chloride homeostasis has a pivotal role in controlling neuronal excitability in the adult brain and during development. The intracellular concentration of chloride is regulated by the dynamic equilibrium between passive fluxes through membrane conductances and the active transport mediated by importers and exporters. In cortical neurons, chloride fluxes are coupled to network activity by the op...

The fertilization rate of mouse gametes in a Krebs-Ringer bicarbonate medium was 60%. The rate fell to 0% when 250 \g=m\M-ZnCl2 was added, but MgCl2, CaCl2, MnCl2, FeCl2 and CuCl2 (each at 250 \g=m\M)had no effect. The inhibitory effect of Zn2+ was not evident if the spermatozoa or eggs were preincubated with Zn2+ or if previously capacitated spermatozoa were used. The Zn2+ is thought to act by...

This study determined if any of four endodontic solutions would have a softening effect on resorcinol-formalin paste and if there were any differences in the solvent action between these solutions. Resorcinol, formalin, and zinc oxide were mixed and allowed to set for 30 days. The solutions tested were 0.9% sodium chloride, 5.25% sodium hypochlorite, chloroform, and Endosolv R. Seven samples pe...
