Kinetics of hydrogen peroxide generated from live and dead ram spermatozoa and the effects of catalase and oxidase substrates addition
reactive oxygen species ram antioxidant
2016/2/23
The generation of hydrogen peroxide (H2O2) by ram spermatozoa (spz) was measured using a flurometric assay with 10-acetyl-3,7-dihydroxyphenoxazine agent as a probe for H2O2 detection. The kinetics of ...
Quercetin Glucosides are Hydrolyzed to Quercetin in Human Oral Cavity to Participate in Peroxidase-Dependent Scavenging of Hydrogen Peroxide
H2O2-scavenging oral cavity peroxidase in saliva

It has been reported that consuming food which contains flavonols is related to the decrease in risks to arteriosclerosis and cancer. One objective of this study was to elucidate the metabolism of que...
Mechanisms and Structural Specificity of Hydrogen Peroxide Formation during Oxidation of Catechins
superoxide anion hydrogen peroxide catechin
2009/6/17
Hydrogen peroxide (H2O2) formed in aqueous solutions of tea catechins such as epicatechin (EC), epicatechin gallate (ECg), epigallocatechin (EGC), and epigallocatechin gallate (EGCg) was measured by a...
Effects of Extracts from Tropical Seaweeds on DPPH Radicals and Caco-2 Cells Treated with Hydrogen Peroxide
Seaweed ethanol extract acetone extract

Edible seaweeds were collected from Indonesia, a tropical country that does not show seasonal variations in temperature, to evaluate their health-related activities. Ethanol and acetone extracts were ...
Production of Catalase-Peroxidase and Continuous Degradation of Hydrogen Peroxide by an Immobilised Alkalothermophilic Bacillus sp.
catalase-peroxidase Bacillus sp. bleaching
2009/3/19
Catalase-peroxidase (CP) production by a Bacillus sp. (Bacillus KF) newly isolated from a textile finishing effluent and by this strain immobilised on light expanded clay was studied. In cultivations ...
Influence of Growth Medium on Hydrogen Peroxide and Bacteriocin Production of Lactobacillus Strains
lactic acid bacteria hydrogen peroxide bacteriocin
2009/3/16
This study was conducted to investigate the inhibitory effect of bacteriocin and the production of hydrogen peroxide by four non-starter lactic acid bacteria, Lactobacillus plantarum 2142, Lactobacill...
Hydrogen Peroxide Formation during Catechin Oxidation Is Inhibited by Superoxide Dismutase
superoxide anion hydrogen peroxide catechin
2010/11/22
We established a simple method to quantify hydrogen peroxide (H2O2) generated during the aerobic heating process of (+)-catechin solution. Using this method, we found that non-enzymatic H2O2 formation...
