The midbrain of the adult homozygous weaver (wv/wv) mouse is notable for a reduction in the numbers of dopamine-containing cells in the substantia nigra (A9) and the retrorubral nucleus (A8). We have determined that the reduction in tyrosine hydroxylase (TH)-positive neurons in the ventral midbrain of the weaver is attributable to the loss of neurons after postnatal day 7 (P7). Because the numb...

BACKGROUND This study aims to validate pro-oxidant actions of nicotine (N), using hydrogen peroxide (H2O2) and the antioxidant glutathione (G) in an in vitro model of human gingival fibroblasts (HGF) and human oral periosteal fibroblasts (HPF); radiolabelled androgens are used as biomarkers of redox status. Oxidative stress is an important mediator of inflammatory repair. The androgen metabolit...

The aim of the present study was to examine the genoprotective and radioprotective effects of black tea extract (BTE) against the induction of single strand DNA breaks in human lymphocytes subjected to hydrogen peroxide (H2O2) or gamma-rays (2 Gy dose). Lymphocytes were incubated with or without different concentrations of BTE (0.005-500 µg/ml) for 30 min, followed by treatment with or without ...

background: natural medicines have been recently considered more reasonable for human use most notably due to their safety and tolerance. hesa-a is a marine-originated herbal medicine with a variety of healing effects. however, its exact biological mechanism is not clear. the pre-sent study aimed at the evaluation of the hesa-a antioxidant effect. methods: chinese hamster ovary (cho) and human ...

in the present study, free-radical-scavenging and antioxidant activities of angipars™, an herbal extract which has been registered as a therapeutic drug for diabetic foot ulcer, were examined. we investigated the protective effect of angipars™ on cytotoxicity produced by exposure to h2o2 (300 µm) in hepg2 and a549 cell lines, using mtt assay, glutathione (gsh) content analysis, and lipid peroxi...

The efficiency of treatment was eliminated based on residual concentration ammonia-nitrogen (NH4-N) and chemical oxygen demand (COD). Removal percentage ammonia in case using H2O2 increased a 30%. the removal organic pollutants recorded high 14.28 10.71% for east El-Burullus Damru drains, respectively. KMnO4 gave better results which, maximum 66.59 % 0.2 g/L Hokx site, whereas COD 34.48 at 0.1o...

BACKGROUND Hydrogen peroxide (H2O2) and reactive oxygen species are implicated in inflammation, ischemia-reperfusion injury, and atherosclerosis. The role of ion channels has not been previously explored. METHODS AND RESULTS K+ currents and membrane potential were recorded in endothelial cells by voltage- and current-clamp techniques. H2O2 elicited both hyperpolarization and depolarization of...

This study provides the basis for implementing a continuous treatment system wastewater containing pesticide mixture formed by atrazine, iprodione, and chlorpyrifos. Two fungal strains (Verticilium sp. H5 Metacordyceps H12) isolated from biomixture of biopurification were able to remove different concentrations (10 50 mg L−1) efficiently liquid medium; however, half-life pesticides was reduced ...
