The ‘oxygen’ in oxygen minimum zones

Environmental Microbiology, 2022
Abstract Aerobic 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).

Understanding Hydrogen: Lessons to Be Learned from Physical Interactions between the Inert Gases and the Globin Superfamily

Oxygen, 2022
Hydrogen gas (molecular hydrogen, H2) has significant effects in a range of organisms, from plants to humans. Many inert gases have been reported to have similar effects, and such responses may be most pronounced when cells are stressed.

Complete Recovery of an Iatrogenic Venous Gaseous Embolism (VGE) Clinical Presentation Thanks to a Timely Hyperbaric Oxygen Therapy (HBOT) Treatment

Oxygen, 2022
Gas embolism is a potentially fatal occurrence in which bubbles are introduced into the arterial/venous circulation. A multifocal ischemia could be the life-threatening scenario of that and occurring after diving-related activities, or pulmonary ...

The oxygen trail: tissue oxygenation [PDF]

British Medical Bulletin, 1999
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.

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 ...

Oxygen-Induced Dimerization of Alkyl-Manganese(II) 2,6-Bisiminopyridine Complexes: Selective Synthesis of a New Ditopic NNN-Pincer Ligand [PDF]

, 2016
The outcome of the reaction of manganese(II) dialkyls with 2,6-bisiminopyridine (BIP) ligands is dramatically altered by the presence of very small amounts of oxygen (< 0.5 mol %), leading to binuclear species.

Impacts of Varying Blood Flow Restriction Cuff Size and Material on Arterial, Venous and Calf Muscle Pump-Mediated Blood Flow

Oxygen, 2023
Blood flow restriction (BFR) may become ineffective or potentially dangerous without sufficient standardization. The purpose of this investigation was therefore to (1) assess the viability of multiple sizes of a novel BFR cuff to determine arterial ...
