Involvement of reactive oxygen species in the bactericidal activity of activated carbon fibre supporting silver; Bactericidal activity of ACF(Ag) mediated by ROS.
TLDR
An activated carbon fibre supporting silver was tested for its antibacterial capacity against Escherichia coli and revealed a strong expression of oxidative stress genes, suggesting that generated bactericidal species were short lifespan.About:

Oxidative mechanisms in the toxicity of metal ions
Sidney J. Stohs,Debasis Bagchi +1 more
TL;DR: Some mechanisms associated with the toxicities of metal ions are very similar to the effects produced by many organic xenobiotics, related to differences in solubilities, absorbability, transport, chemical reactions, and the complexes that are formed within the body.
Journal ArticleDOI
The Haber-Weiss reaction and mechanisms of toxicity.
TL;DR: Through studies at this level, a better understanding of free radicals as both signaling molecules and toxic species is reached, which makes it obvious that disruptions of free radical production or defenses at many different levels can lead to adverse effects on cells.
Journal ArticleDOI
Genome-wide expression monitoring in Saccharomyces cerevisiae
TL;DR: The genomic sequence of the budding yeast Saccharomyces cerevisiae has been used to design and synthesize high-density oligonucleotide arrays for monitoring the expression levels of nearly all yeast genes, and many of the genes observed to be differentially expressed under these conditions are expected, but large differences are also observed.

Hydrogen peroxide as an antibacterial factor in zinc oxide powder slurry
Jun Sawai,Shinobu Shoji,Hideo Igarashi,Atsushi Hashimoto,Takao Kokugan,Masaru Shimizu,Hiromitsu Kojima +6 more
TL;DR: Using four kinds of antibiotics, an investigation was made to determine whether or not H2O2 generated from a ZnO powder slurry was related to its antibacterial activity as mentioned in this paper.

Bimodal pattern of killing of DNA-repair-defective or anoxically grown Escherichia coli by hydrogen peroxide.
James A. Imlay,Stuart Linn +1 more
TL;DR: Two modes of killing of Escherichia coli K-12 by hydrogen peroxide can be distinguished: mode-one killing required active metabolism during the H2O2 challenge, and it resulted in sfiA-independent filamentation of both cells which survived and those which were killed by the challenge; and mode-two killing did not require active metabolism, and killed cells did not filament, although survivors demonstrated a dose-dependent growth lag.
