Oxygen (O(2)) is a vital element. Shortage of O(2) results in deranged metabolism and important changes in vascular tone with opposite effects on the systemic and pulmonary circulation. During hypoxemia, oxidative stress exposes the organism to a sort of accelerated senescence as well as to several acute untoward effects.

Understanding Catalytic Activity Trends in the Oxygen Reduction Reaction.
Chemical Reviews, 2018Despite the dedicated search for novel catalysts for fuel cell applications, the intrinsic oxygen reduction reaction (ORR) activity of materials has not improved significantly over the past decade.

Like most bacteria, Escherichia coli has a flexible and branched respiratory chain that enables the prokaryote to live under a variety of environmental conditions, from highly aerobic to completely anaerobic. In general, the bacterial respiratory chain is composed of dehydrogenases, a quinone pool, and reductases ...

Nitrogen-doped graphene as efficient metal-free electrocatalyst for oxygen reduction in fuel cells.
ACS Nano, 2010Nitrogen-doped graphene (N-graphene) was synthesized by chemical vapor deposition of methane in the presence of ammonia. The resultant N-graphene was demonstrated to act as a metal-free electrode with a much better electrocatalytic activity, long-term ...

Nature, 1932 MR. ODELL'S remarks,1 regarding Dr. Argyll Campbell's experiments, which were designed to test the power of acclimatisation of animals to low oxygen pressure, are not quite accurate. These experiments were undertaken to supply information that was wanting, and to endeavour to explain the adverse symptoms recorded in the official reports of the Everest ...

Interest in developing a method for predicting arterial oxygen tension following changes in inspired oxygen concentration (FIO2) has existed since the advent of oxygen therapy. Hess [1] has published a predictive formula to accomplish this, and Abizanda and Lopez [2,3] have presented the same method in a different form.

Skin Permeability to Oxygen and Hyperbaric Oxygen
Archives of Surgery, 1970It has been assumed that exposure to oxygen and hyperbaric oxygen (HPO) is beneficial to hypoxic skin in part because oxygen directly penetrates the tissues. Thus, it was felt necessary to determine the extent of tissue permeability to oxygen in terms of elevation of the tissue oxygen tension (TOT).

The relationship between oxygen demand, oxygen uptake, and oxygen supply
Intensive Care Medicine, 1990Results of the relationships between oxygen supply, demand, and uptake can be used to interpret cardiac output values, identify types of acute circulatory failure, guide attempts to improve cellular function, and thus prevent the development of multiple organ failure and death. Five steps in the interpretation of cardiac output values are recommended: (
