this study investigated the influence of inoculation with an arbuscular mycorrhizal fungus (amf), glomus mosseae (nicol & gerd.) on growth and antioxidant enzyme activities (sod, cat, gupx) in shoots and roots of wheat (triticum aestivum l.) affected by three different levels of salt stress. the experiment was arranged as a factorial in randomized complete block design (rcbd) with three replicat...

effects of yeast extract (ye) (0, 0.05, 0.1, 0.2, 0.5 and 1%) were investigated on rosmarinic acid (ra) accumulation and tyrosine aminotransferase (tat) gene expression in melissa officinalis seedlings at different time intervals (4 and 17 hours). based on the results, only ye concentrations of 0.05%, 0.1%, and 0.2%, for the 17-hour treatment, significantly stimulated ra biosynthesis pathway. a...

Sci., 20: 883-887 The participation of antioxidant defence under mild and severe salt stress conditions (120 and 240 mM) on barley (Hordeum vulgare L.) seedlings in different growth stages, antioxidant enzyme (super...

OBJECTIVE To investigate the possible relationships between plasma bilirubin levels and concentrations of nitric oxide (NO), malondialdehyde (MDA), and erythrocyte antioxidant enzyme activities in newborn infants with hyperbilirubinemia. METHODS Thirty term (gestational age > or = 37 weeks) newborn infants with indirect hyperbilirubinemia aged less than 10 days were prospectively recruited in...

understanding the physiological processes associated with drought stress lead to an understanding of the basic mechanisms of resistance, maintaining yield potential and contribute to the identification of drought tolerant cultivars. for this purpose, the effects of drought stress in cowpea genotypes was evaluated using five different genotypes with different yield potential in a pot experiment ...

Soybeans (Glycine max Merr.) were grown at elevated carbon dioxide concentration ([CO(2)]) or chronic elevated ozone concentration ([O(3)]; 90 ppb), and then exposed to an acute O(3) stress (200 ppb for 4 h) in order to test the hypothesis that the atmospheric environment alters the total antioxidant capacity of plants, and their capacity to respond to an acute oxidative stress. Total antioxida...

In this study, we investigated the cardioprotective effects of resveratrol. Rats were intraperitoneally administered with resveratrol (25 mg/kg bw) or vehicle (ethanol 10%) for 7 days and their heart subjected to ischemia/reperfusion injury. Isolated hearts were langendorff perfused, left ventricular functions as heart rate and developed pressure, as well as, heart antioxidant status were deter...
