Oxygen‐sensing mechanisms in cells [PDF]

The FEBS Journal, 2020
The importance of oxygen for the survival of multicellular and aerobic organisms is well established and documented. Over the years, increased knowledge of its use for bioenergetics has placed oxygen at the centre of research on mitochondria and ATP‐generating processes.

Conscious prone positioning in a pregnant patient with COVID-19 respiratory distress: A case report and review

Case Reports in Women's Health, 2021
Prone positioning has been used for decades to improve oxygenation in patients with acute respiratory distress syndrome. With the COVID-19 pandemic there has been a growing emphasis on the utilization of prone positioning for non-intubated patients as a ...

Study of sewage oxygenation treatment based on gas magnetization mechanism

Water Science and Technology, 2022
In the process of sewage treatment, the sewage usually needs to be aerated, so the oxygenation efficiency is an important indicator for the aerator. The general oxygenation technique is to inject large amount of natural air into the aeration tank over ...

Effects of anesthetic agents on brain blood oxygenation level revealed with ultra-high field MRI. [PDF]

PLoS ONE, 2012
During general anesthesia it is crucial to control systemic hemodynamics and oxygenation levels. However, anesthetic agents can affect cerebral hemodynamics and metabolism in a drug-dependent manner, while systemic hemodynamics is stable.

Oxygenation inhibits the physiological tissue-protecting mechanism and thereby exacerbates acute inflammatory lung injury. [PDF]

PLoS Biology, 2005
Acute respiratory distress syndrome (ARDS) usually requires symptomatic supportive therapy by intubation and mechanical ventilation with the supplemental use of high oxygen concentrations.

Successful bronchial artery embolization using hydrogel coils for hemoptysis during extracorporeal membrane oxygenation

Radiology Case Reports, 2022
A 58-year-old woman with bronchiectasis presented with massive hemoptysis and severe respiratory failure, which required long-term extracorporeal membrane oxygenation with continuous heparin infusion.

Discovery of a linoleate 9S-dioxygenase and an allene oxide synthase in a fusion protein of Fusarium oxysporum[S]

Journal of Lipid Research, 2013
Fusarium oxysporum is a devastating plant pathogen that oxidizes C18 fatty acids sequentially to jasmonates. The genome codes for putative dioxygenase (DOX)-cytochrome P450 (CYP) fusion proteins homologous to linoleate diol synthases (LDSs) and the ...

Manganese lipoxygenase of F. oxysporum and the structural basis for biosynthesis of distinct 11-hydroperoxy stereoisomers

Journal of Lipid Research, 2015
The biosynthesis of jasmonates in plants is initiated by 13S-lipoxygenase (LOX), but details of jasmonate biosynthesis by fungi, including Fusarium oxysporum, are unknown. The genome of F.

Mechanism of Oxygen Deficit.

Experimental Biology and Medicine, 1956
SummaryIn muscular exercise, a considerable oxygen deficit is incurred which cannot be explained by the accumulation of lactic acid. The hypothesis that this deficit is due to depletion of high energy phosphate in muscle and that the oxygen consumption is increased by an increase in phosphate acceptor was tested in the perfused dog gastrocnemius ...
