Contaminant Degradation by •OH during Sediment Oxygenation: Dependence on Fe(II) Species.
Environmental Science and Technology, 2020It has been documented that contaminants could be degraded by hydroxyl radicals (•OH) produced upon oxygenation of Fe(II)-bearing sediments. However, the dependence of contaminant degradation on sediment characteristics, particularly Fe(II) species ...

Oxygen transport— the oxygen delivery controversy
Intensive Care Medicine, 2004Most cellular activities require energy in the form of oxygen, primarily obtained from the degradation of adenosine triphosphate (ATP) and other high-energy compounds. Oxygen must be present in sufficient amounts in the mitochondria to maintain effective concentrations of ATP in the electron transport system.

Oxygen therapy and oxygen toxicity
Annals of Emergency Medicine, 1983When oxygen therapy is warranted, the minimum effective dose generally should be given. Hypoxemic patients who have normal baseline ABG may be treated initially with an intermediate to high FiO2 in the range of 35% to 100%, depending on the severity of the respiratory distress. The majority of patients with exacerbations of COPD who are not in extremis

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 ...

Hypoxia, and hypoxia inducible factor-1 (HIF-1), can induce tumor resistance to radiation therapy. To overcome hypoxia-induced radiation resistance, recent studies have described nanosystems to improve tumor oxygenation for immobilizing DNA damage and ...

Oxygenation is a fundamental transformation in synthesis. However, equivalent oxidants and active oxygen species are the foremost reasons which limit efficient discrimination in various oxygenation states of certain atom and selectivity among different ...

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.

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 ...
