carnation (dianthus caryophyllus l.) is one of the most important cut flowers in the world. themajority of thecarnation cultivars are sensitive to ethylene which affected the physiological and biochemical postharvest characteristics of these flowers.applying inhibitors of biosynthesis and action of ethylene is important factor to protect the display quality and extend postharvest life. in order...
ferula gummosa boiss is a good source of biologically active compounds such as monoterpene and sesquiterpene derivatives. there are also several reports on antioxidant effects of these compounds. the aim of this study was to investigate the effect of daily administration of f. gummosa root hydro-alcoholic extract on serum oxidant-antioxidant status. twenty four wistar rats were randomly divided...
Gel filtration chromatography using a Superose 12 HR column gave well-resolved and similar elution patterns for the maize extract, Baxtin and Polbax samples. Fractions exhibiting superoxide dismutase activity, determined by direct KO2 assay, were combined, dialysed and evaporated to dryness. The molecular weight of these fractions was approximately 30000 d. These fractions were also analyzed by...
Survival of rats exposed to 100% oxygen was increased from 69.5 +/- 1.5 to 118.1 +/- 9.9 h (mean +/- SEM, P less than 0.05) when liposomes containing catalase and superoxide dismutase were injected intravenously before and during exposure. The increased survival time in 100% oxygen was also associated with significantly less fluid in the pleural cavity. Rats injected with catalase- and superoxi...
Parkinson's disease (PD) is a progressive neurodegenerative disease characterized by loss of neurons in the substantia nigra that project to the striatum and release dopamine. The cause of PD remains uncertain, however, evidence implicates mitochondrial dysfunction and oxidative stress. Although most cases of PD are sporadic, 5-10% of cases are caused by inherited mutations. Loss-of-function mu...
In this review we describe the potential role(s) of superoxide in inflammatory disorders.
An Escherichia coli double mutant, sodAsodB, that is deficient in both bacterial superoxide dismutases (Mn superoxide dismutase and iron superoxide dismutase) is unable to grow on minimal medium in the presence of oxygen and exhibits increased sensitivity to paraquat and hydrogen peroxide. Expression of the evolutionarily unrelated eukaryotic CuZn superoxide dismutase in the sodAsodB E. coli mu...
Escherichia coli apomanganese superoxide dismutase, prepared by removing the native metal ion under denaturing conditions, exhibits thermally triggered metal uptake behavior previously observed for thermophilic and hyperthermophilic superoxide dismutases but over a lower temperature range. Differential scanning calorimetry of aposuperoxide dismutase and metalated superoxide dismutase unfolding ...
A mouse fibrosarcoma cell line (FSa-II), which exhibits low endogenous levels of manganese Superoxide dismutase, was transfected with a human manganese Superoxide dismutase complementary DNA. Fifty clones were screened for manganese Superoxide dismutase activity by the Superoxide dismutase activity gel assay. Activity of the positive clones was measured by the nitro blue tetrazolium-reduction a...
