Post-Mortem Extracorporeal Membrane Oxygenation Perfusion Rat Model: A Feasibility Study
Animals, 2023 The development of biomedical soft- or hardware frequently includes testing in animals. However, large efforts have been made to reduce the number of animal experiments, according to the 3Rs principle.

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 ...

The Hemovent Oxygenator: A New Low-Resistance, High-Performance Oxygenator.
ASAIO journal (1992), 2020 Extracorporeal membrane oxygenation (ECMO) and extracorporeal carbon dioxide removal (ECCO2R) provide respiratory support aimed at gaining time to allow patient’s recovery from hypoxemic and/or hypercapnic respiratory failure, respectively.1 However, in ...

Journal of Translational Medicine, 2021 Background Extracorporeal membrane oxygenation (ECMO) research using large animals requires a significant amount of resources, slowing down the development of new means of ECMO anticoagulation. Therefore, this study developed and evaluated a new rat ECMO

On the maximum value of the cosmic abundance of oxygen and the oxygen yield [PDF]
Mon.Not.Roy.Astron.Soc.376:353-360,2007, 2007 We search for the maximum oxygen abundance in spiral galaxies. Because this maximum value is expected to occur in the centers of the most luminous galaxies, we have constructed the luminosity - central metallicity diagram for spiral galaxies, based on a large compilation of existing data on oxygen abundances of HII regions in spiral galaxies.

Mathematics, 2023 Membrane artificial lungs (oxygenators) are used in cardiopulmonary surgery as well as, in some cases, in severe lung disease to support the natural lung by means of ECMO (extracorporeal membrane oxygenation). The oxygen and carbon dioxide transfer rates

Constraining the rise of oxygen with oxygen isotopes [PDF]
Nature Communications, 2019 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 ...

A new liver perfusion and preservation system for transplantation Research in large animals [PDF]
, 1990 A kidney perfusion machine, model MOX-100 (Waters Instruments, Ltd, Rochester, MN) was modified to allow continuous perfusion of the portal vein and pulsatile perfusion of the hepatic artery of the liver. Additional apparatus consists of a cooling system,
