The main objective of this study is to evaluate the anti-oxidant properties in methanolic extract of Leaves and fruit of cucumies melo () The methanol leaf extract noticed significant scavenging activity on DPPH, superoxide, nitric oxide , hydrogen peroxide and hydroxyl radical. The total phenolic compounds were found to be high with leaves rather than the flesh of fruit.
Background: There is clear evidence to support the importance of regular physical activity and the use of antioxidants in the prevention or control of cardiovascular diseases, especially those that cause cardiac apoptosis. Our aim in this study was to determine the simultaneous effect of six weeks forced swimming and Crocin supplementation on the expression of 3 cardiomyocyte gene caspase in ma...
Chocolate is a product consumed worldwide and it stands out for presenting an important amount of phenolic compounds. In this study, the total phenolic content and antioxidant activity in the cerebral cortex, hippocampus, and cerebellum of male Wistar rats when consuming different types of chocolate, including milk, semisweet, dark, and soy, was evaluated. The total polyphenols concentration an...
This study the effect of seed preparation (priming) with different concentrations of hydrogen peroxide on the anatomy of the flag leaf and spike two wheat genotypes( Cross Sabalan ( bread wheat) and Saji(durum wheat)) and its relationship with grain yield, under dry land farming system condition, Experimental design was factorial, arranged in randomized complete block. Results showed that the n...
there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
environmental pollution by 2,4-dicholorphenol (2,4-dcp), commonly found in industrial wastewater has been a concern for humans over the past 50 years. garden radish peroxidase (grp) can eliminate this poisonous pollutant. the aim of this study was to apply an experimental response surface methodology (rsm) and central composite design (ccd) to optimize grp-based treatment in order to maximize t...
Background: Due to the large volume of water consumed in textile industry and producing the colored wastewater containing non-biodegradable organic dyes, in the present study the interaction of hydrogen peroxide and nanophotocatalyst in the advanced oxidation process was investigated. Methods: In this research, after synthesizing of nanophotocatalyst (ZnO:Ag:Nd) the effect of hydrogen peroxide ...
Salinity is one of the most important abiotic stresses that have restricted affects on plant growth and yield. Magnetic field can ameliorate the negative effect of salinity with induction of plant antioxidant activity. In present research, the effect of static magnetic fields (0 anf 4 mT) on some physiological parameters and antioxidative capacity were investigated under salinity stress at conc...
BACKGROUND The Cheilanthes albomarginata Clarke (CA), a fern belonging to Pteridaceae family, is found mainly in India, Nepal, Pakistan and Bhutan at an altitude of 1300-2700 m. It grows mostly in the rock crevices on slopes. Juice from the rhizome of CA has been used to treat peptic ulcer. In this study, the biological activities (antioxidant, anti-inflammatory, anti-adipogenic and anti-obesit...
Concentration of hydrogen peroxide to military grade (about 98 wt%) needs removal of impurities from hydrogen peroxide of commercial grade. In this research, separation of metallic impurities from hydrogen peroxide solution was studied and cations as Al, Fe, Pb, Zn and Cr were separated from commercial hydrogen peroxide using Amberlite IR-120 (strong cationic resin). The cations were separate...
