Objective(s): Human superoxide dismutase 1 (SOD1) is the cytosolic form of this enzyme it detoxifies superoxide anions and attenuates their toxicities and concomitant detrimental effects on the cells. It is believed that the amount of these enzymes present in the oxidative stress-induced diseases is crucial for preventing disease progression. Transfection of rat bone marrow stromal cells (BMSCs...

the aims of this study were to assess the effects of drought stress on peroxidase (pod), superoxide dismutase (sod) and catalase (cat) activities as well as free proline content and growth parameters of pistacia khinjuk seedlings under drought stress. therefore, the one-year seedlings of pistacia khinjuk subjected to water stress (25%, 50%, 75%, and 100% field capacity) for 8 months in greenhou...

cadmium is considered as a common residue in water and sediments which could readily enter aquatic organisms. the aim of this study was to evaluate the time- and concentration-dependent changes in antioxidant enzymes (sod and cat) activities as well as concentration of mda as a bi- product of lipid peroxidation in the liver of persian sturgeon, acipenser persicus , following cdcl 2 exposure at ...

introduction: considering the prevalence of epilepsy and the failure of available treatments for many epileptic patients, finding more effective drugs in the treatment of epilepsy seems necessary. oxidative stress has a special role in the pathogenesis of epileptic syndrome. therefore, in the present study, we have examined the anti-epileptic and anti-oxidant properties of the ferula assa foeti...

We have targeted the expression of recombinant human extracellular superoxide dismutase, a glycosylated tetrameric metalloprotein, to the mammary gland of transgenic mice. This was achieved by using regulatory elements from either the murine whey acidic protein gene or the ovine beta-lactoglobulin gene to control expression of human extracellular superoxide dismutase cDNA. Whey acidic protein r...

Two proteins (P1 and P2, with weights of 57,500 and 27,500 respectively) were isolated from Euglena gracilis. Both proteins show cyanide-insensitive superoxide dismutase activity in the "classical" superoxide dismutase assay, using xanthine-xanthine oxidase as O2.- generator. If O2.- is generated chemically (autoxidation of reduced anthraquinone), photochemically (illuminated riboflavine) or pu...

Formation of the first binary stacks of an intact organocopper aggregate with the arenes naphthalene and 2,2'-bithiophene is reported; crystallographic data suggest that the supramolecular assembly process is supported by Cu-pi, Cu-S, and perfluoroarene-arene pi-interactions.

An unprecedented 2-D Cu-S network is constructed by self-assembly coordination between Cu(I) and 4-hydroxythiophenol and its structure was determined by using powder X-ray diffraction data. The self-assembled coordination network displays ionic behavior with a bulk electrical conductivity value of 120 S cm(-1).
