Genetics of human superoxide dismutase [PDF]
Hereditas, 2009 The formal genetics of superoxide dismutase has been studied in a family material from northern Sweden. The results verify the hypothesis that the three phenotypes SOD 1, SOD 2–1 and SOD 2 are controlled by two autosomal alleles. Although the SOD2 gene appears to be associated with somewhat lower enzyme activity, the SOD 2–1 and SOD 2 types were found ...

Scanning Electron Microscopy and Metabolite Measurement Revealed the Stress Mechanism of PS-COOH Microplastics on Rhodotorula mucilaginosa AN5 [PDF]
arXiv, 2022 Microplastics in the marine environment have been paid more and more attention by researchers, and the impact of these substances on marine microorganisms can not be ignored. Studies have shown that PS-COOH Microplastics are harmful to marine molluscs, algae and monads.

Molecular responses of mouse macrophages to copper and copper oxide nanoparticles inferred from proteomic analyses [PDF]
Mol Cell Proteomics 12, 11 (2013) 3108-22, 2013 The molecular responses of macrophages to copper-based nanoparticles have been investigated via a combination of proteomic and biochemical approaches, using the RAW264.7 cell line as a model. Both metallic copper and copper oxide nanoparticles have been tested, with copper ion and zirconium oxide nanoparticles used as controls.

Detoxification of superoxide without production of H2O2: antioxidant activity of superoxide reductase complexed with ferrocyanide [PDF]
proceedings of the national Academy of Sciences of the United
States of America, PNAS, 2006, pp.14750-5, 2015 The superoxide radical O(2)(-.) is a toxic by-product of oxygen metabolism. Two O(2)(-.) detoxifying enzymes have been described so far, superoxide dismutase and superoxide reductase (SOR), both forming H2O2 as a reaction product. Recently, the SOR active site, a ferrous iron in a [Fe(2+) (N-His)(4) (S-Cys)] pentacoordination, was shown to have the ...

Catalase, glutathione peroxidase, metabolic syndrome, superoxide dismutase
Majalah Kedokteran Bandung, 2012 Labor pain is part of a normal process, which often causes physiological and psychological stress to mother. These stress have impact to both mother and fetus. Largely (90%) labor comes with pain and in some cases severe pain.

The enzyme-like catalytic activity of cerium oxide nanoparticles and its dependency on Ce3+ surface area concentration [PDF]
Nanoscale 10, 6971 - 6980 (2018), 2018 Cerium oxide nanoparticles are known to catalyze the decomposition of reactive oxygen species such as superoxide radical and hydrogen peroxide. Herein, we examine the superoxide dismutase (SOD) and catalase (CAT) mimetic catalytic activities of nanoceria and demonstrate the existence of generic behaviors.

Superoxide Dismutase Mimics [PDF]
Antioxidants & Redox Signaling, 2011 Dear Editor: We write to correct some of the misleading descriptions of our research in a Comprehensive Invited Review “Superoxide Dismutase Mimics: Chemistry, Pharmacology, and Therapeutic Potential” by Dr. Ines Batinic-Haberle and colleagues (1). We wish to correct two factual errors and then discuss a matter of opinion.
