Oxygen metabolism and oxygenation of the newborn [PDF]
The premature infant is to some extent protected from hypoxia, however defense against hyperoxia is poorly developed. The optimal assessment of oxygenation is to measure oxygen delivery and extraction. At the bedside PaO2 and SpO2 are approximations of oxygenation at the tissue level.

The ‘oxygen’ in oxygen minimum zones
AbstractAerobic processes require oxygen, and anaerobic processes are typically hindered by it. In many places in the global ocean, oxygen is completely removed at mid‐water depths forming anoxic oxygen minimum zones (A‐OMZs). Within the oxygen gradients linking oxygenated waters with A‐OMZs, there is a transition from aerobic to anaerobic microbial ...

An oxygen-reducing biocathode with “oxygen tanks” [PDF]
Polytetrafluoroethylene submicro-rod, serving as “oxygen tanks” and binders, have been mixed into Os redox polymer-based bilirubin oxidase cathodes, leading to enhanced performance.

The oxygen trail: tissue oxygenation [PDF]
Aerobic cellular respiration depends on the efficient supply of oxygen and substrate to the mitochondria. There is an oxygen cascade from the environment to the subcellular environment. Efficient oxygen delivery depends on the coordinated interaction between the respiratory and circulatory systems.

Shining new light on mammalian diving physiology using wearable near-infrared spectroscopy [PDF]
Investigation of marine mammal dive-by-dive blood distribution and oxygenation has been limited by a lack of non-invasive technology for use in freely diving animals.

Alkalinization during re-oxygenation prevents functional damage by hyperglycaemic hypoxia [PDF]
HYPERGLYCAEMIA impairs recovery from transient cerebral ischaemia: the importance of tissue acidification for this phenomenon has not been clarified in detail.

The Role of rescue therapies in the treatment of severe ARDS [PDF]
ARDS is characterized by a non-cardiogenic pulmonary edema with bilateral chest radiograph opacities and hypoxemia refractory to oxygen therapy. It is a common cause of admission to the ICU due to hypoxemic respiratory failure requiring mechanical ...

Three dimensional optical imaging of blood volume and oxygenation in the neonatal brain [PDF]
Optical methods provide a means of monitoring cerebral oxygenation in newborn infants at risk of brain injury. A 32-channel optical imaging system has been developed with the aim of reconstructing three-dimensional images of regional blood volume and ...

Constraining the rise of oxygen with oxygen isotopes [PDF]
AbstractAfter permanent atmospheric oxygenation, anomalous sulfur isotope compositions were lost from sedimentary rocks, demonstrating that atmospheric chemistry ceded its control of Earth’s surficial sulfur cycle to weathering. However, mixed signals of anoxia and oxygenation in the sulfur isotope record between 2.5 to 2.3 billion years (Ga) ago ...
