Oxygen metabolism and oxygenation of the newborn [PDF]
Seminars in Fetal and Neonatal Medicine, 2020 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
Environmental Microbiology, 2022 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]
Chemical Communications, 2020 Polytetrafluoroethylene submicro-rod, serving as “oxygen tanks” and binders, have been mixed into Os redox polymer-based bilirubin oxidase cathodes, leading to enhanced performance.

RONS and Oxidative Stress: An Overview of Basic Concepts
Oxygen, 2022 Oxidative stress (OS) has greatly interested the research community in understanding damaging processes occurring in cells. OS is triggered by an imbalance between reactive oxygen species (ROS) production and their elimination by the antioxidant system ...

May oxygen depletion explain the FLASH effect? A chemical track structure analysis [PDF]
, 2021 Background and purpose: Recent observations in animal models show that ultra-high dose rate ("FLASH") radiation treatment significantly reduces normal tissue toxicity maintaining an equivalent tumor control. The dependence of this "FLASH" effect on target oxygenation has led to the assumption that oxygen "depletion" could be its major driving force ...
