Baseline oxygen consumption decreases with cortical depth.

PLoS Biology, 2022
The cerebral cortex is organized in cortical layers that differ in their cellular density, composition, and wiring. Cortical laminar architecture is also readily revealed by staining for cytochrome oxidase-the last enzyme in the respiratory electron ...

Substantial oxygen consumption by aerobic nitrite oxidation in oceanic oxygen minimum zones

Nature Communications, 2021
Oxygen is fundamental for marine life, yet it is absent from large areas of the ocean. Here the authors demonstrate that microbial nitrite oxidation effectively consumes oxygen where oxygen concentrations are low, playing a pivotal role in these regions.

Metabolically exaggerated cardiac reactions to acute psychological stress revisited [PDF]

, 2009
The reactivity hypothesis postulates that large magnitude cardiovascular reactions to psychological stress contribute to the development of pathology. A key but little tested assumption is that such reactions are metabolically exaggerated.

Oxygen consumption dynamics in steady-state tumour models [PDF]

Royal Society Open Science, 2014
Oxygen levels in cancerous tissue can have a significant effect on treatment response: hypoxic tissue is both more radioresistant and more chemoresistant than well-oxygenated tissue.

Maximal oxygen consumption and oxygen uptake efficiency in adolescent males

Journal of Exercise Science & Fitness, 2021
Background/objective: Measures of oxygen uptake efficiency (OUE) have been used to evaluate cardiorespiratory fitness (CRF) in adolescents unable to perform maximal exercise. The oxygen uptake efficiency slope (OUES) and oxygen uptake efficiency plateau (

SGLT2 inhibition reduces myocardial oxygen consumption

Metabolism Open, 2022
Aims/hypothesis: SGLT2 inhibition is associated with a reduced risk of cardiac disease that is still largely unexplained. According to one hypothesis, improved myocardial energetics may explain the cardioprotective effects of SGLT2i.

Energy Consumption Optimization of a Synthetic Ammonia Process Based on Oxygen Purity

Chemical Engineering Transactions, 2018
The energy consumption of an ammonia process is huge, and it occupies a large proportion in the industrial energy consumption. The air separation unit is an important energy-consuming unit in the process of ammonia synthesis. For the ammonia process with

The effects on arterial haemoglobin oxygen saturation and on shunt of increasing cardiac output with dopamine or dobutamine during one-lung ventilation [PDF]

, 2004
Publisher's copy made available with the permission of the publisher © Australian Society of AnaesthetistsTheoretically, if the cardiac output were increased in the presence of a given intrapulmonary shunt, the arterial saturation should improve as the ...
