Reactive oxygen species
Reactive oxygen species (ROS) are chemically reactive molecules containing oxygen. Examples include oxygen ions and peroxides. ROS are formed as a natural byproduct of the normal metabolism of oxygen...

Oxidative stress
Oxidative stress reflects an imbalance between the systemic manifestation of reactive oxygen species and a biological system's ability to readily detoxify the reactive intermediates or to repair the r...
Maximum operating depth
In underwater diving activities such as saturation diving, technical diving and nitrox diving, the maximum operating depth (MOD) of a breathing gas is the depth below which the partial pressure of oxy...
Nitrox
Nitrox refers to any gas mixture composed (excluding trace gases) of nitrogen and oxygen; this includes normal air which is approximately 78% nitrogen, 21% oxygen, and 1% other gases, primarily argon...

Superoxide dismutase
Superoxide dismutases (SOD, EC 1.15.1.1) are enzymes that alternately catalyze the dismutation (or partitioning) of the superoxide (O2) radical into either ordinary molecular oxygen (O2) or hydrogen p...
