Copper- and Zinc-containing Superoxide Dismutase Can Act as a Superoxide Reductase and a Superoxide Oxidase [PDF]

Journal of Biological Chemistry, 2000
The copper- and zinc-containing superoxide dismutase can catalyze the oxidation of ferrocyanide by O(2) as well as the reduction of ferricyanide by O(2). Thus, it can act as a superoxide dismutase (SOD), a superoxide reductase (SOR), and a superoxide oxidase (SOO).

MitoNeoD:a mitochondria-targeted superoxide probe [PDF]

, 2017
Mitochondrial superoxide (O2⋅−) underlies much oxidative damage and redox signaling. Fluorescent probes can detect O2⋅−, but are of limited applicability in vivo, while in cells their usefulness is constrained by side reactions and DNA intercalation.

Topical Benefits of Two Fucoidan-Rich Extracts from Marine Macroalgae

Cosmetics, 2015
Two concentrated and well-characterized fucoidan-rich extracts were investigated to determine their benefits in topical applications. An Undaria pinnatifida extract, containing 85% fucoidan, and a Fucus vesiculosus co-extract, containing 60% fucoidan and

Anti-Inflammatory CeO₂ Nanoparticles Prevented Cytotoxicity Due to Exogenous Nitric Oxide Donors via Induction Rather Than Inhibition of Superoxide/Nitric Oxide in HUVE Cells

Molecules, 2021
The mechanism behind the cytoprotective potential of cerium oxide nanoparticles (CeO2 NPs) against cytotoxic nitric oxide (NO) donors and H2O2 is still not clear.

A simple method for clinical assay of superoxide dismutase.

Clinical Chemistry, 1988
This assay for superoxide dismutase (SOD, EC 1.15.1.1) activity involves inhibition of nitroblue tetrazolium reduction, with xanthine-xanthine oxidase used as a superoxide generator.

S-adenosylmethionine and superoxide dismutase 1 synergistically counteract Alzheimer's disease features progression in tgCRND8 mice [PDF]

, 2017
Recent evidence emphasizes the role of dysregulated one-carbon metabolism in Alzheimer's Disease (AD). Exploiting a nutritional B-vitamin deficiency paradigm, we have previously shown that PSEN1 and BACE1 activity is modulated by one-carbon metabolism ...
