( 2003) Micromolar Concentrations of Hydrogen Peroxide Induce Oxidative DNA Lesions More Efficiently Than Millimolar Concentrations in Mammalian Cells. Nucleic Acids Res., 31, 1790-1795.Nakamura, J., Purvis, E.R., and Swenberg, J.A. (2003). Micromolar concentrations of hydrogen peroxide induce ...
A high concentration of hydrogen peroxide production method, a hydrogen peroxide solution was prepared by the anthraquinone high concentrated hydrogen peroxide product approach, while providing a means for the method. 采用两套生产装置连续生产,首先通过树脂床对过氧化氢去除有机物,然后进入两套生产装置,每套...
The concentration of hydrogen peroxide (H 2O 2) in distilled water, drinking water and in different types of surface and rain waters can be easily determined by a photometric method in which N,N-diethyl- p-phenylenediamine (DPD) is oxidized by a peroxidase catalyzed reaction. DPD is available...
Hydrogen peroxide concentrations are reported for the first time in the surface low salinity layer (LSL) and underlying saline layer (SL) of a fiord. Measurements were made in Deep Cove and Hall Arm in Doubtful Sound, New Zealand under contrasting climatic conditions in early summer (October; ...
a氨过量导致的碱性环境、双氧水过量加入或双氧水浓度过高以及氨肟化反应不完全是引起双氧水分解的主要原因; The ammonia excessive causes the alkalinity environment, the hydrogen peroxide solution excessive join or the hydrogen peroxide solution density excessively are high as well as the ammonia wo response inc...
An increase in the intracellular generation of reactive oxy- gen species (ROS), such as superoxide (O2 •–) and hydrogen peroxide (H2O2), or a defect in the anti-oxidant defense system renders the cells oxidatively stressed. Oxidative stress has often been referred to as a statedoi:...
Objectives The aim of this study was to evaluate color longevity after a year of in-office bleaching with gel (6% hydrogen peroxide HP, LED blue/laser infrared activation system) compared to a 35% control concentration in a split-mouth study model. Materials and Methods Thirty-one patients wer...
aEffect of hydrogen peroxide production and the Fenton reaction on membrane composition of Streptococcus pneumoniae 过氧化氢生产的作用和Fenton反应在膜结构的链球菌pneumoniae[translate] asignificant when low concentrations of oxidant are added, 重大,当氧化剂的低集中增加,[translate]...
Combined use of exhaled hydrogen peroxide and nitric oxide in monitoring asthma. Oxidative stress contributes to airway inflammation and exhaled hydrogen peroxide (H2O2) and nitric oxide (NO) are elevated in asthmatic patients. We deter...

Millimolar concentrations of ascorbic acid (millimolar ascorbate) in cell culture media and biological fluids may cause the generation of hydrogen peroxide (H 2 O 2 )via ascorbate auto-oxidation and reduction of molecular oxygen. Although many cancer cell lines appear to be particularly susceptible ...
