Therefore, treatment of dental infections with low dose hydrogen peroxide (H O) may offer a non-antibiotic alterative. Without effective sustained treatment aimed at eliminating the pathogens and mediators of the inflammatory response, ultimate destruction of periodontal structures can lead to tooth and...

aok well i can do anything to it you want 好井我可以做任何东西到您要的它 [translate] aCAT catalyzes dismutation of toxic hydrogen peroxide [18], is a major determinant of cellular resistance to hydrogen peroxide toxicity. A high level of CAT activity has been proved to be protective against...
Hydrogen peroxide (H2O2) is produced predominantly in plant cells during photosynthesis and photorespiration, and to a lesser extent, in respiration processes. It is the most stable of the so-called reactive oxygen species (ROS), and therefore plays a crucial role as a signalling molecule in vari...
Hydrogen peroxide produced by spermine and BSAO stimulated pentose cycle activity, whereas the aldehyde(s) did not. Depletion of intracellular glutathione with L-buthionine sulfoximine (1 mM, 24 h) sensitized cells to the cytotoxic effects of both H 2 0 2 and the aldehyde(s) produced by ...
Cardiac Response to Chronic Intermittent Hypoxia with a Transition from Adaptation to Maladaptation:The Role of Hydrogen Peroxide Xia Yin,Yang Zheng,Quan Liu,Jun Cai,Lu Cai Oxidative Medicine and Cellular Longevity First Published:20 May 2012
The upregulation of L-ferritin and H-ferritin levels indicates a protective mechanism against potential oxidative damage in cells due to the production of hydrogen peroxide that occurs during iron release. Although such oxidative damage may not result in cytotoxicity, it could have secondary effects ...
Notably, all response patterns were not associated to morphological indications of cell suffering or cell death as shown by optical images (Fig.4for 8-day-HEK-cFXN, 10-tet-HEK-cFXNand 100-tet-HEK-cFXNrespectively). Figure 4 Effects of hydrogen peroxide on the cell morphology. Optical images...
The copper/zinc-SOD down-regulation was apparently due to the calcium (Ca) deficiency induced by the heavy metal. In these circumstances, the overproduction of the ROS hydrogen peroxide and Superoxide could be observed in vivo by confocal laser microscopy, mainly associated with vascular tissue, ...
Superoxide (O2) and hydrogen peroxide (H2O2) are the proximal ROS formed by the mitochondria, and the latter molecule is used as a secondary messenger to coordinate oxidative metabolism with changes in cell physiology. Like any other secondary messenger, H2O2levels need to be regulated through its...
