Process for the preparation of calcium superoxide [PDF]
, 1978 Calcium superoxide is prepared in high yields by spreading a quantity of calcium peroxide diperoxyhydrate on the surface of a container, positioning said container in a vacuum chamber on a support structure through which a coolant fluid can be circulated,

The Regulation of Trace Metal Elements in Cancer Ferroptosis
Advanced Biology, EarlyView.The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.

Fluorescent Detection of Reactive Oxygen Species in \u3cem\u3eSaccharomyces cerevisiae\u3c/em\u3e Applied to Chronological Lifespan [PDF]
, 2019 During the course of normal aerobic metabolism, cells are exposed to a wide range of reactive oxygen species such as the superoxide anion, hydrogen peroxide, and the hydroxyl radical. These reactive oxygen species (ROS) are highly reactive metabolites of

Advanced Functional Materials, EarlyView.Fe‐cationic and P‐anionic coordination, as fabricated in Co0.75Fe0.25P/MWCNTs, effectively optimizes the adsorption of OER intermediates (OH*, O*), promoting direct O*─O* coupling and avoiding the formation of unstable OOH* intermediate. This process is accompanied by an asynchronous transfer of electrons and protons, resulting in the formation of a ...

Atrial Natriuretic Peptide Induces Mitogen-Activated Protein Kinase Phosphatase-1 in Human Endothelial Cells via Rac1 and NAD(P)H Oxidase/Nox2-Activation [PDF]
, 2005 The cardiovascular hormone atrial natriuretic peptide (ANP) exerts anti-inflammatory effects on tumor necrosis factor-α–activated endothelial cells by inducing mitogen-activated protein kinase (MAPK) phosphatase-1 (MKP-1).
