AIM To determine direct protective effect of monosialoganglioside (GM1) on hippocampal slices after oxygen-glucose deprivation and reperfusion (OGD/RP), and investigate the influence on the expression of N-methyl-D-aspartate receptor subunit 1 (NMDAR1) in those hippocampal slices. METHODS Injury of hippocampal slices and protective effects of GM1 were detected by 2,3,5-triphenyltetrazolium ch...

Toluidine blue and toluidine blue-nanogold mixtures were incorporated into polyurethane and silicone polymers by a swell-encapsulation-shrink method using acetone-water mixtures. The surface and mechanical properties of the polymers were changed by the swell-shrink process especially the Young’s modulus, but not by the introduction of toluidine blue or nanogold. The antibacterial properties of ...

sulphide was determined spectrophotometrically at 628 nm and ph 6.7 based on its catalytic reduction of toluidine blue in the presence of se(iv) using a flow injection system. after optimization of the measuring conditions the calibration curve was found linear up to 25 mg/ml and the detection limit was 0.3 mg/ml (30 ml injections). the relative standard deviation for the determination of 10 mg...

Background The solid and colloidal particles in the range of 1-100 nm are called nanoparticles. Recently, one of the most important metal nanoparticles, with wide usage is gold nanoparticle. Based on the previous studies, gold nanoparticles have spermatotoxic effects and can destroy sperm motility. The aim of present study is the effect of gold nanoparticles on chromatin quality and sperm param...
