Molecular biomarkers of oxidative stress in aquatic organisms in relation to toxic environmental pollutants.
TLDR
Current knowledge and advances in the understanding of oxidative processes in biological systems are summarized and this knowledge is extended to specific applications in aquatic organisms because of their sensitivity to oxidative pollutants, their filtration capacity, and their potential for environmental toxicology studies.About:

Oxidative stress response and gene expression with atrazine exposure in adult female zebrafish (Danio rerio).
Yuanxiang Jin,Xiangxiang Zhang,Linjun Shu,Lifang Chen,Liwei Sun,Haifeng Qian,Weiping Liu,Zhengwei Fu +7 more
TL;DR: This is the first report to study the transcriptional effects of ATZ stress on zebrafish, and the information presented in this study will be helpful in fully understanding the mechanism of oxidative stress induced by ATZ in fish.

A method to measure total antioxidant capacity against peroxyl radicals in aquatic organisms: application to evaluate microcystins toxicity.
Lílian Lund Amado,Márcia Longaray Garcia,Patrícia Baptista Ramos,Ricardo F. Freitas,Bruna Zafalon,Josencler L. Ribas Ferreira,João Sarkis Yunes,José Maria Monserrat +7 more
TL;DR: The use of antioxidant defenses was efficient in avoiding oxidative damage, as the content of oxidized proteins was not altered and the potential of this new methodology to be used in ecotoxicological studies is shown.
Journal ArticleDOI
Acute ZnO nanoparticles exposure induces developmental toxicity, oxidative stress and DNA damage in embryo-larval zebrafish
TL;DR: The nano-ZnO was found to exert a dose-dependent toxicity to zebrafish embryos and larvae, reducing the hatching rate and inducing malformation and the acute toxicity toZn(2+) embryos was greater than that of the Zn( 2+) solution.

Critical Review of rate constants for reactions of hydrated electrons, hydrogen atoms and hydroxyl radicals (⋅OH/⋅O− in Aqueous Solution
TL;DR: In this article, the rate constants for over 3500 reaction are tabulated, including reaction with molecules, ions and other radicals derived from inorganic and organic solutes, and the corresponding radical anions, ⋅O− and eaq−, have been critically pulse radiolysis, flash photolysis and other methods.

Free Radicals in the Physiological Control of Cell Function
TL;DR: There is growing evidence that aging involves, in addition, progressive changes in free radical-mediated regulatory processes that result in altered gene expression.

Oxidants, oxidative stress and the biology of ageing.
Toren Finkel,Nikki J. Holbrook +1 more
TL;DR: Evidence that the appropriate and inappropriate production of oxidants, together with the ability of organisms to respond to oxidative stress, is intricately connected to ageing and life span is reviewed.
