Overview

Oxygen is the diatomic element (O2) essential for aerobic life, serving as the terminal electron acceptor in mitochondrial respiration and thereby underpinning efficient energy production. Its electronic structure makes it both indispensable and potentially hazardous, because partial reduction of molecular oxygen generates reactive oxygen species such as the superoxide anion radical, hydrogen peroxide, and the hydroxyl radical, while related forms including singlet oxygen and ozone are still more reactive. These species participate in signalling and host defence at controlled levels but cause oxidative damage to lipids, proteins, and nucleic acids when their generation outpaces antioxidant defences, a state termed oxidative stress that is implicated in ageing, ischaemia-reperfusion injury, and metabolic and degenerative disease. Measurement of oxygen status, reactive intermediates, and antioxidant capacity is therefore central to redox biology. Research published in this area by the journal examines oxygen and its reactive derivatives in this light, including the oxidative effects of ozone and oxygen on testicular mitochondria, antioxidative protection of sperm mitochondria by ozone therapy, non-enzymatic formation of methylglyoxal and superoxide during glycation, radical-scavenging and antioxidative activities in cardiomyoblast cells, regulation of reactive oxygen intermediates during malaria infection, and alveolar-arterial oxygen gradients in respiratory disease. These contributions span free-radical biochemistry, oxidative stress, and the assessment of antioxidant and oxygen-related processes.
