HIF-1 mediates adaptation to hypoxia by actively downregulating mitochondrial oxygen consumption.

open access: yesCell Metabolism, 2006
The HIF-1 transcription factor drives hypoxic gene expression changes that are thought to be adaptive for cells exposed to a reduced-oxygen environment. For example, HIF-1 induces the expression of glycolytic genes.

Anaesthesia-Specifi c Oxygen Transport Assessment in Robot-Assisted Pelvic Surgery: a Clinical Trial

open access: yesКреативная хирургия и онкология, 2021
Background. Robot-assisted pelvic surgery rapidly becomes a choice in surgeries for gynaecological oncology and urology. These interventions require special settings (pneumoperitonaeum and Trendelenburg position), which inevitably and systemically impact

Baseline oxygen consumption decreases with cortical depth.

open access: yesPLoS 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 ...

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

open access: yesChemical 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

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

open access: yesNature 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.

Comparison of methods for measuring oxygen consumption rate of Hyriopsis cumingii

open access: yes浙江大学学报. 农业与生命科学版, 2013
Oxygen consumption rate is an important physiological indicator for evaluating the environmental adaptation of bivalves. Generally, oxygen consumption rate of bivalve is measured with closed respirometry or flow-through respirometry.
