Redox Mechanism of Reactive Oxygen Species in Exercise [PDF]
Frontiers in Physiology, 2016 It is well known that regular exercise can benefit health by enhancing antioxidant defenses in the body. However, unaccustomed and/or exhaustive exercise can generate excessive reactive oxygen species (ROS), leading to oxidative stress-related tissue damages and impaired muscle contractility.

What Triggers Oxygen Loss in Oxygen Redox Cathode Materials? [PDF]
Chemistry of Materials, 2019 It is possible to increase the charge capacity of transition-metal (TM) oxide cathodes in alkali-ion batteries by invoking redox reactions on the oxygen. However, oxygen loss often occurs. To explore what affects oxygen loss in oxygen redox materials, we have compared two analogous Na-ion cathodes, P2-Na0.67Mg0.28Mn0.72O2 and P2-Na0.78Li0.25Mn0.75O2 ...

Molecular Controls of the Oxygenation and Redox Reactions of Hemoglobin [PDF]
Antioxidants & Redox Signaling, 2013 The broad classes of O(2)-binding proteins known as hemoglobins (Hbs) carry out oxygenation and redox functions that allow organisms with significantly different physiological demands to exist in a wide range of environments. This is aided by allosteric controls that modulate the protein's redox reactions as well as its O(2)-binding functions.The ...
