the aim followed in this study was to compare the performance of multiple regression vs neural network models to predict the activity of antioxidant enzymes super oxide dismutase (sod), cat alase (cat), ascorbate pero xidase (apx) and peroxidase (pox) in the shoots of wheat (triticum aestivum), alvand cultivar in a soil polluted with cadmium. the treatments consisted of four levels of cadmium (...

Highlight Research Snakehead fish head possess high protein content and potential to be used as materials for hydrolysate hydrolysis optimum condition were determined antioxidant activity analyzed is Abstract There concern regarding the use of synthetic antioxidants which spurred yearly increase natural substitute ones. Fish (FPH), has been reported have potent properties, could utilized solve ...

Oxidative damage and antioxidant responses were compared in two cotton cultivars: drought-resistant (CCRI-60) and drought-sensitive (CCRI-27). Cotton seedlings were subjected to PEG-6000 solutions with two different osmotic potentials, and changes in the antioxidant enzyme activities were investigated. Increasing PEG concentration reduced root length and vigor, increased H2O2, malondialdehyde (...

In order to investigate physiological and biochemical changes of wheat under stress residue of Imazethapyr herbicide (Imazethapyr), an experiment was conducted in a completely randomized design with four replications in greenhouse conditions at university of Mohaghegh Ardebili. The treatments consisted of five dose levels of herbicide Imazethapyr (0, 0.011, 0.022, 0.033 and 0.044 micrograms of ...

fruit and leaves of junipers are commonly used internally as tea and pounded fruits are eaten to lower blood glucose levels in anatolia. thus, we aimed to evaluate antidiabetic and antioxidant potential and the chemical profile of juniperus foetidissima willd. and j. sabina l. in this study. in-vitro antidiabetic activities of leaf and fruit extracts were examined by their inhibitory activity o...

objective: alchornea floribunda leaves are widely used in ethnomedicine for the management of immuno-inflammatory disorders. we investigated the in vivo and in vitro antioxidant activity of the leaf extract, fractions and isolated compounds of a. floribunda.materials and methods: the ethyl acetate fraction of the methanol leaf extract was subjected to several chromatographic separations to isol...

In order to study the effect of external ethylene on postharvest display and activity of some senescence-related enzymes in potted miniature roses, this experiment was carried out in a completely randomized design, using three treatment levels with three replications. In glass chambers, potted miniature rose plants were exposed to ethylene concentrations of 0, 5 and 10 μL L-1 for 12 h. The resu...

There is an individual susceptibility to diabetic nephropathy, and oxidative stress is believed to play an important role in the pathogenesis of diabetic complications. Active oxygen species induce antioxidant enzyme expression in tissues, an effect considered to be a defensive mechanism. To test whether altered intracellular antioxidant enzyme production might explain the predisposition to dia...

In this experiment, wheat plants were exposed to drought stress during seed development then we worked on the obtained seeds. The seed mitochondrial ultra-structure, and antioxidant enzymes in seedling were investigated after exposure to seed accelerated ageing. Drought stress during seed development induced some changes in mitochondrial ultra-structure. Encountering seed development to drought...
