oxidative addition reactions of 1,4-diiodo-butane and 1,3-diiodo-propane with [ptme2(ph2phen)]; in which ph2phen=4,7-diphenyl-1,10-phenanthroline, were studied in different solvents such as acetone and benzene.oxidative addition reaction of [pt me2(ph2phen)] with i(ch2)4i and i(ch2)3i produced the [pt me2i(ch2)4(ph2phen)i] (1a) and [pt me2i(ch2)3(ph2phen)i] (1b).all the platinum (iv) products w...
Background and purpose: Polycystic ovary syndrome (PCOS) is one of the most common causes of infertility in modern societies. The etiology of PCOS is unknown, so a good animal model can be valuable in studying its pathogenesis and could help in making a more effective diagnosis and choosing appropriate treatments. All PCOS disorders may be the result of multiple genetic and environmental fact...
Oxidative stress is an important mechanism of chemical toxicity, contributing to teratogenesis and to cardiovascular and neurodegenerative diseases. Developing animals may be especially sensitive to chemicals causing oxidative stress. The developmental expression and inducibility of anti-oxidant defenses through activation of NF-E2-related factor 2 (NRF2) affect susceptibility to oxidants, but ...
Oxidative stress caused by high levels of reactive oxygen species (ROS) has been correlated with prostate cancer aggressiveness. Expression of membrane-type 1 matrix metalloproteinase (MT1-MMP), which has been implicated in cancer invasion and metastasis, is associated with advanced prostate cancer. We show here that MT1-MMP plays a key role in eliciting oxidative stress in prostate cancer cell...
Background and Aims: Metabolic syndrome, a common metabolic disorder, for the serious health consequences such as insulin resistance and lipid abnormalities has been considered as a major clinical challenge with obscure causes. Oxidative stress is an important component of metabolic syndrome, contributing in its development. Troxerutin, a semi-synthetic derivative of natural bioflavonoid rutin,...
OBJECTIVE To investigate the association of hypertension coexisting with diabetes mellitus with oxidative stress and inflammation in the kidneys of streptozotocin (STZ)-induced diabetic rats. MATERIALS AND METHODS Male Wistar rats were used for the experiments. Blood glucose (BG), urea, blood pressure (BP), and heart rate (HR) were analyzed before and 48 h after STZ injection. Further, these ...
Fas ligand (FasL) on cytotoxic lymphocytes is important for mediating apoptosis of activated lymphocytes and other target cells. We have reported that NK cell functions, such as proliferation, cell death, and killing activity, are subject to regulation by cellular redox status. Here, we report that expression of FasL protein and mRNA in activated NK cells is also regulated by redox. Ligation of...
Previously published studies have shown that cytochrome P450 (P450) enzyme systems can produce reactive oxygen species and suggest roles of P450s in oxidative stress. However, most of the studies have been done in vitro, and the potential link between P450 induction and in vivo oxidative damage has not been rigorously explored with validated biomarkers. Male Sprague-Dawley rats were pretreated ...
conclusions the obtained results indicate that rsm is an effective method for the optimization of culture conditions for hes gene expression in e. coli. results a maximum rhes mrna level of 376.16% was obtained under the following conditions: 0.6 mm iptg, 7 hours post-induction time, and 0.9 cell density before induction. the level of rhes mrna was significantly correlated with post-induction t...
