infrared spectra of some deuterio analogues of carboxylic acids in heavy water have been investigated and their spectral behavior in carbonyl stretching frequency region have been interpreted in terms of their structural behavior in aqueous solutions. it has been shown that a linear relationship exists between carbonyl stretching frequency of solvated acids at infinite dilution and their pk s .

Advanced glycation end products (AGEs) play an important factor for pathophysiology of diabetes and its complications. Moringa oleifera is one of the medicinal plants that have anti-hyperglycemic activity. However, anti-glycation property of Moringa oleifera leaf extract on the different types of reducing monosaccharides-induced protein glycation has not been investigated. Therefore, the aim of...

The present work has been undertaken to study the effect of ambrex, a polyherbal formulation on experimental gastric ulceration and their possible antioxidative mechanism to cure ulcer. Gastric mucosal damage was produced in rats by administering 200 mg/kg orally. Aspirin was found to cause severe haemorrhagic lesions mainly through oxidative damage of the mucosa as indicated by increased lipid...

Heme-carbonyl complexes are widely exploited for the insight they provide into the structural basis of function in heme-based proteins, by revealing the nature of their bonded and nonbonded interactions with the protein. This report presents two novel results which clearly establish a FeCO vibrational signature for crystallographically verified pentacoordination. First, anisotropy in the NRVS d...

The transport of precursor proteins into mitochondria requires an energized inner membrane. We report here that the import of various precursor proteins showed a differential sensitivity to treatment of the mitochondria with the uncoupler carbonyl cyanide m-chlorophenylhydrazone. The differential inhibition by carbonyl cyanide m-chlorophenylhydrazone was not influenced by the length of the prec...

Studies have indicated that sports anemia is mainly associated with intravascular hemolysis induced by exercise. We hypothesized that such exercise-induced hemolysis leads to oxidative damage due to an increase in free iron caused by hematocyte destruction. Thirty-one male ICR mice were randomly divided into 3 groups: a rested control group, an intense-exercise group, and a group rested for 24 ...
