Hydrogen peroxide signalling

Current Opinion in Plant Biology, 2002
Recent biochemical and genetic studies confirm that hydrogen peroxide is a signalling molecule in plants that mediates responses to abiotic and biotic stresses. Signalling roles for hydrogen peroxide during abscisic-acid-mediated stomatal closure, auxin-regulated root gravitropism and tolerance of oxygen deprivation are now evident.

Hydrogen Peroxide Poisoning

Toxicological Reviews, 2004
Hydrogen peroxide is an oxidising agent that is used in a number of household products, including general-purpose disinfectants, chlorine-free bleaches, fabric stain removers, contact lens disinfectants and hair dyes, and it is a component of some tooth whitening products.

Reactions of Hydrogen Atom with Hydrogen Peroxide

The Journal of Physical Chemistry A, 2007
Rate coefficients are calculated using canonical variational transition state theory with multidimensional tunneling (CVT/SCT) for the reactions H + H2O2 --> H2O + OH (1a) and H + H2O2 --> HO2 + H2 (1b). Reaction barrier heights are determined using two theoretical approaches: (i) comparison of parametrized rate coefficient calculations employing CVT ...

Hydrogen peroxide proctitis

The American Journal of Surgery, 1951
Abstract There is no doubt that enemas using hydrogen peroxide solutions are effective in relieving fecal impactions. It is apparent, however, that the strength of the solutions used must be closely supervised in order to avoid complications. In my experience no more than 30 cc. (1 ounce) or at most 60 cc. (2 ounces) of a U. S. P.

Hydrogen Peroxide and Cancer

Nature, 1958
AFTER consultation with Holman, his experiment1 was repeated as closely as possible in all details, except the strain of rat used, which was an inbred strain of Wistar origin. Experimental animals and controls carried tumours of the 9th, 10th, 11th and 15th successive transplants into this strain of a Walker carcinoma obtained from the Chester Beatty ...

Regulation of Translation by Hydrogen Peroxide

Antioxidants & Redox Signaling, 2011
Cells must be able to maintain their intracellular homeostasis in the face of changing conditions. Typically, they respond by invoking complex regulatory mechanisms, including a global inhibition of translation. This reduction in protein synthesis may prevent continued gene expression during potentially error-prone conditions as ...

Hydrogen Peroxide

2023
The paper discusses the decomposition mechanisms of hydrogen peroxide (HP) under the action of light, with the involvement of metal ions and their coordination compounds, as well as the participation of hydrogen peroxide in the peroxidase oxidation of various chemical substances.
