The serotonin(1A) (5-HT(1A)) receptor is an important member of the superfamily of seven transmembrane domain G-protein-coupled receptors. We have examined the modulatory role of cholesterol on the ligand binding of the bovine hippocampal 5-HT(1A) receptor by cholesterol complexation in native membranes using digitonin. Complexation of cholesterol from bovine hippocampal membranes using digiton...

Thin films of silver selenide have been prepared by chemical bath deposition technique at substrate temperature of 300K. The films were characterized by X-ray diffraction and UV-VIS spectrophotometer. Silver selenide thin films are polycrystalline with orthorhombic structure, confirmed by x-ray diffractogram. The deposition parameters were optimized to obtain good quality thin films. The film d...

2-(3- indolyl) – 4,5 di phynyl imidazole.(IDPI) was used as a complexing agent in cloud point extraction for the first time and applied for selective pre-concentration of trace amounts of cadmium. The method is based on the extraction of cadmium at pH= 7.0 by using non-ionic surfactant Triton-X114 and 2-(3- indolyl) – 4,5 di phynyl imidazole. (IDPI) as a chelating agent. The adopted concentrati...

A Competitive spectrophotometric method has been used for the study of complexation between Cu2+, Zn2+ and Cd2+ (M) and 18-crown-6(18C6, B) in methanol using 4-(2-thiazolylazo) resorcinol (TAR, HL) as the colorimetric complexant. Absorption spectra of the species in the M-TAR-18 C6 system at a various concentrations of 18C6 showed no formation of ternary com...

A novel method combined theoretical and experimental study for environmental friendly silver electroplating was introduced. Quantum chemical calculations and molecular dynamic (MD) simulations were employed for predicting the behaviour and function of the complexing agents. Electronic properties, orbital information, and single point energies of the 5,5-dimethylhydantoin (DMH), nicotinic acid (...

Abstract We report the use of carbon nanotubes as a material for preparation an electrochemical sensor that acts substrate film metal electrodes used in stripping voltammetry. The is based on mixture multiwall nanotubes, glassy spherical powder, and epoxy resin. properly selected composition made it possible to obtain new substrate, competitive relation carbon, creating electrodes. In this work...

The persistence of infectious diseases that continue to plague the world, as well formation harmful substances within human body, such free radicals and reactive oxygen species (ROS) have sparked new research. Thus, need for innovative approaches developing or modification existing therapeutic agents. The design biologically important metal complexes dithiocarbamates (DTCs) has been made...
