Magnetism of sodium superoxide [PDF]
CrystEngComm, 2013 By combining first-principles electronic-structure calculations with the model Hamiltonian approach, we systematically study the magnetic properties of sodium superoxide (NaO2), originating from interacting superoxide molecules.

Scavenging of superoxide by a membrane-bound superoxide oxidase [PDF]
Nature Chemical Biology, 2018 Superoxide is a reactive oxygen species produced during aerobic metabolism in mitochondria and prokaryotes. It causes damage to lipids, proteins and DNA and is implicated in cancer, cardiovascular disease, neurodegenerative disorders and aging. As protection, cells express soluble superoxide dismutases, disproportionating superoxide to oxygen and ...

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

Carbon-sulfur bond strength in methanesulfinate and benzenesulfinate ligands directs decomposition of Np(v) and Pu(v) coordination complexes. [PDF]
, 2020 Gas-phase coordination complexes of actinyl(v) cations, AnO2+, provide a basis to assess fundamental aspects of actinide chemistry. Electrospray ionization of solutions containing an actinyl cation and sulfonate anion CH3SO2- or C6H5SO2- generated ...

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 ...

Metallic Aluminum Suboxides with Ultrahigh Electrical Conductivity at High Pressure
Research, 2022 Aluminum, as the most abundant metallic elemental content in the Earth’s crust, usually exists in the form of alumina (Al2O3). However, the oxidation state of aluminum and the crystal structures of aluminum oxides in the pressure range of planetary ...

Superoxide dismutase in leukocytes [PDF]
FEBS Letters, 1974 1 ] or NBT [ 141 in the xanthine-xanthine oxidase reaction. The reduction of NBT and cytochrome c was followed at 560 and 550 nm respectively. One unit of SOD activity is defined as the amount of enzyme that causes a decrease of the optical density from 0.025 to 0.0125 in 1 min using 1 cm light path cuvette.
