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
2009/6/18
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 ...

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...
Involvement of Hydrogen Peroxide Formation on Apoptosis Induction by Olive Oil Phenolic Compounds
olive oil phenols apoptosis hydrogen peroxide
2014/3/10
In the present investigation the ability of different phenolic compounds, either present or not in olive oil, to induce both apoptosis on tumour cells and H2O2 accumulation in cell culture medium was ...
Comparison of Newly Isolated Strains of Lactobacillus delbrueckii subsp. lactis for Hydrogen Peroxide Production at 5°C
Lactobacillus hydrogen peroxide
2008/4/1
Isolates of Lactobacillus delbrueckii subsp. lactis obtained from raw milk samples were compared for the ability to produce hydrogen peroxide (H2O2)at 5°C. Nineteen out of 101 lactobacilli isolated we...
Hydrogen Peroxide Production and Oxidation of Ferrous Iron by Lactobacillus delbrueckii ssp. bulgaricus
iron hydrogen peroxide Lactobacillus delbrueckii ssp. bulgaricus
2008/3/25
Hydrogen peroxide was produced by Lactobacillus delbrueckii ssp. bulgaricus ATCC 11842 only in the presence of glucose at pH 6.5 and 5.0 in the presence of air. Production of H2O2 was minimal followin...
Suppression of Hydrogen Peroxide-Induced Cytotoxicity toward Chinese Hamster Lung Fibroblasts by Chemically Modified Curcumin
V79 cytotoxicity polyphenol cultured cell
