Accelerated discovery of superoxide-dismutase nanozymes via high-throughput computational screening
Nature Communications, 2021 A general predicting theory for superoxide-dismutase mimicking nanomaterials is currently lacking. The present manuscript reports a density functional theory study on the superoxides dismutase-like activity of nanomaterials based on their electronic band

COX-2-derived prostanoids and oxidative stress additionally reduce endothelium-mediated relaxation in old type 2 diabetic rats. [PDF]
PLoS ONE, 2013 Endothelial dysfunction in resistance arteries alters end organ perfusion in type 2 diabetes. Superoxides and cyclooxygenase-2 (COX-2) derivatives have been shown separately to alter endothelium-mediated relaxation in aging and diabetes but their role in

Simulation studies of Cu(II) removal from aqueous solution using olive stone
Cleaner Materials, 2022 Heavy metal pollution is a growing environmental and health concern. Heavy metal ions, like Cu(II), undergo the Fenton reaction, producing hydroxide radicals and superoxides that cause DNA mutation (crosslinking and depurination) and carcinogenic damage ...

Charge Transport in Alkali-Metal Superoxides: A Systematic First-Principles Study
Chemistry of Materials, 2019 Charge-transport mechanisms within the discharge products of alkali-metal/O2 batteries can strongly influence the performance of these systems. To date, discharge products comprising alkali peroxides (Li2O2 and Na2O2) and superoxides (LiO2, NaO2, and KO2)

Superoxide Dismutases and Superoxide Reductases
Chemical Reviews, 2014 Superoxide, O2•–, is formed in all living organisms that come in contact with air, and, depending upon its biological context, it may act as a signaling agent, a toxic species, or a harmless intermediate that decomposes spontaneously. Its levels are limited in vivo by two different types of enzymes, superoxide reductase (SOR) and superoxide dismutase ...
