An L-glutathione-functionalized silica adsorbent was applied in this study to remove malathion from aqueous media. This has demonstrated an improved adsorption efficiency of malathion. The maximum uptake achieved 130 mg g?1 at pH 8. Equilibrium reached after about 90 min. A pseudo-second-order model best described the kinetics. isotherms were simulated by Freundlich model. functional groups are...

Mice treated with buthionine sulfoximine, an inhibitor of glutathione synthesis, showed striking alterations of morphology of lung type 2 cell lamellar bodies (swelling and disintegration) and mitochondria (degeneration) and of lung capillary endothelial cells (mitochondrial swelling). These effects probably may be ascribed to glutathione deficiency; administration of glutathione monoester prot...

the study was designed with an aim to evaluate the protective effects of reduced glutathione on cyclophosphamide induced lipid peroxidation and also changes in cholesterol content. goat liver and white new zealand rabbit were used as lipid source for the models. lipid peroxidation study was performed by measuring the malondialdehyde, 4-hydroxy-2-nonenal, reduced glutathione and nitric oxide con...

Kinetic and binding studies with substrates, products, and a spin-labeled product analogue of glutathione (sl-glutathione) have been used to characterize the kinetic mechanism and properties of the catalytic site of the homodimer YaYa of glutathione S-transferase. Product inhibition studies and inhibition by sl-glutathione indicate the random addition of substrates. The kinetically determined d...

glutathione s-transferase (gst) is a superfamily enzyme which plays a major role indetoxification of xenobiotic compounds by catalyzing the conjugation of xenobiotic to cellular glutathione(gsh). gst-p is an important class of gsts which is expressed during the early stage of life and duringdevelopmental stages. its activity is relatively high during embryogenesis and immediately after birth an...

three levels of lysine (90, 100 and 110% of ross requirement) and of pyridoxine (3, 6 and 9 mg kg-1) were used in a 3 × 3 factorial experiment to investigate the growth and blood antioxidant ability of broilers under high ambient temperature. none of the dietary supplements affected the weight gain during the starter and grower periods. although no significant differences were detected between ...

this work analyzes the effects of satureja khuzestanica essential oil (skeo) on the thyroid and antioxidant system, assessed by measuring levels of tri-iodothyronine (t3), thyroxine (t4), thyroid-stimulating hormone (tsh), malondialdehyde (mda), reduced glutathione (gsh), and glutathione peroxidase (gpx) activity. forty adult male sprague dawley rats (225 ± 25 g) were divided into five equal gr...

due to the binding of the –coo- group with the mercury (ii), gold nanoparticlesfunctionalized with glutathione can self-assemble to form a supermolecular network in the hac-naac buffer solution. the aggregation of functionalized gold nanoparticles and mercury (ii)caused the shift of maximum absorption peak of the uv-vis spectrum from 520 nm to 609 nm.based on this principle, a simple spectropho...
