02

The general availability of pure 02 in cylinders gave medicine a powerful therapeutic tool. Until 1952 oxygen was used freely in high concentrations in many premature baby units, in the knowledge that many babies were hypoxic and on the assumption that it would in any case do no harm. The demonstration that high concentrations of inspired 02 could lead to retrolental fibroplasia in premature ba...

BACKGROUND Reduction of brain volume (brain atrophy) during healthy brain aging is well documented and dependent on genetic, lifestyle and environmental factors. Here we investigated the possible dependence of brain gray matter volume reduction in the absence of the Human Leukocyte Antigen (HLA) allele DRB1*13:02 which prevents brain atrophy in Gulf War Illness (James et al., 2017). METHODS S...

Oxygen Kinetics of Frozen Cytochrome Oxidase

2005

Cytochrome c oxidase (EC 1.9.3.1) is the site of 02 utilization in the inner mitochondrial membrane of all higher organisms. It contains two haems (a and a3) and two copper atoms. Reduced haem a3 is able to bind 02 and catalyse its reduction to water. Flash photolysis of CO-inhibited cytochrome oxidase in the presence of 02 at low temperatures (-95 to -1250C) leads to the formation of oxycytoch...
