Most of the nutraceutical plants, plants associated products and foods are known for their promising antioxidant properties due to the presence of several metabolites like polyphenolic compounds, flavonoids, terpenoids, vitamin C and many other. These molecules have strong tendency to scavenge the free radicals (reactive oxygen species) generated inside our body system due to the various reasons. Out of several methods for the antioxidant activity determination; hydrogen peroxide scavenging activity is an important method.

During this time the containment must withstand physical stress and corrosion. It is important for a safety analysis to determine the different reactions that could occur during this time.

The disproportionation of H₂O₂ to H₂O and molecular O₂ catalyzed by platinum nanocatalysts is technologically very important in several energy conversion technologies, such as steam propellant thrust applications and hydrogen fuel cells. However, the mechanism of H₂O₂ decomposition on platinum has been unresolved for more than 100 years and the kinetics of this reaction were poorly understood. Our goal was to quantify the effect of reaction conditions and catalyst properties on the decomposition of H₂O₂ by platinum nanocatalysts and determine the mechanism and rate-limiting step of the reactio

Abstract:
In this study, the mechanisms of antiradical activity of the previously synthesized 4,7- dihydroxycoumarin derivative:(E)-3-(1-((4-hydroxyphenyl)amino)ethylidene)-2,4- dioxochroman-7-yl acetate (A-4OH) according to the series of chloromethylperoxy radicals: OOCH2Cl (chloromethylperoxy), OOCHCl2 (dichloromethylperoxy) and OOCCl3 (trichloromethyl peroxy) were investigated. To assess the mechanisms of antiradical activity of A-4OH against chloromethylperoxy radicals, the following mechanistic pathways were examined: Hydrogen Atom Transfer (HAT), Single-Electron Transfer followed by Proton Transfe

Abstract:
Original objectives (revisions from original proposal are highlighted) 1. Elucidate the direct effects O3 and H2O2 on guard cell function, utilizing assays of stomatal response in isolated epidermal peels and whole cell gas exchange. 2. Determine the mechanistic basis of O3 and H2O2 effects on the plasma membrane through application of the electrophysiological technique of patch clamping to isolated guard cells. 3. Determine the relative sensitivity of Israeli cultivars of economically important crops to O3 and determine whether differential leaf conductance responses to O3 can explain relativ

Abstract:
To elucidate the role of ROS in the tri-trophic interactions in postharvest biocontrol systems a detailed molecular and biochemical investigation was undertaken. The application of the yeast biocontrol agent Metschnikowia fructicola, microarray analysis was performed on grapefruit surface wounds using an Affymetrix Citrus GeneChip. the data indicated that 1007 putative unigenes showed significant expression changes following wounding and yeast application relative to wounded controls. The expression of the genes encoding Respiratory burst oxidase (Rbo), mitogen-activated protein kinase (MAPK)
