COX-2-derived prostanoids and oxidative stress additionally reduce endothelium-mediated relaxation in old type 2 diabetic rats. [PDF]

open access: yesPLoS 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

Regulatory effect of bacterial melanin on the isoforms of new superoxide-producing associates from rat tissues in rotenone-induced Parkinson’s disease

open access: yesBMC Neuroscience, 2023
According to recent research, selective neuronal vulnerability in Parkinson’s disease (PD) results from several phenotypic traits, including calcium-dependent, feed-forward control of mitochondrial respiration leading to elevated reactive oxygen species ...

Simulation studies of Cu(II) removal from aqueous solution using olive stone

open access: yesCleaner 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 ...

Superoxide Dismutases and Superoxide Reductases

open access: yesChemical 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

open access: yesResearch, 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 ...

Catalytically active gold clusters with atomic precision for noninvasive early intervention of neurotrauma

open access: yesJournal of Nanobiotechnology, 2021
Background Neurotrauma is a worldwide public health problem which can be divided into primary and secondary damge. The primary damge is caused by external forces and triggers the overproduction of peroxides and superoxides, leading to long-lasting ...
