Glucose uptake as an alternative to oxygen uptake for assessing metabolic rate in Danio rerio larvae

open access: yesCurrent Research in Physiology, 2022
Respirometry, based on oxygen uptake, is commonly employed for measuring metabolic rate. There is a growing need for metabolic rate measurements suitable for developmental studies, particularly in Danio rerio, where many important developmental stages ...

The effects of capillary transit time heterogeneity (CTH) on the cerebral uptake of glucose and glucose analogs:Application to FDG and comparison to oxygen uptake.

open access: yesFrontiers in Computational Neuroscience, 2016
Glucose is the brain’s principal source of ATP, but the extent to which cerebral glucose consumption (CMRglc) is coupled with its oxygen consumption (CMRO2) remains unclear.

Effects of constant magnetic fields on respiration of rainbow trout (Oncorhynchus mykiss Walb.) embryos [PDF]

open access: yesActa Ichthyologica et Piscatoria, 1997
Oxygen uptake and carbon dioxide release by rainbow trout (Oncorhynchus mykiss Walb.) embryos exposed to constant magnetic fields of 5 and 10 mT (oxygen uptake and carbon dioxide release) and 50, 150, and 300 mT (oxygen uptake) were measured.

Impact of deforestation on carbon dioxide capture and oxygen supply in Paraguay. Period 1990-2020

open access: yesPoblación y Desarrollo, 2022
Breathing is a necessity for the human being, the oxygen found in the air is of vital importance. Therefore, preserving air quality becomes relevant. This research focuses on the importance of the forest area both for the provision of oxygen and for the ...

The dependence of maximum oxygen uptake and utilization (V̇O2max) on hemoglobin‐oxygen affinity and altitude

open access: yesPhysiological Reports, 2023
Oxygen transport from the lungs to peripheral tissue is dependent on the affinity of hemoglobin for oxygen. Recent experimental data have suggested that the maximum human capacity for oxygen uptake and utilization (V̇O2max) at sea level and altitude ...

Hyperoxia reversibly alters oxygen consumption and metabolism [PDF]

open access: yes, 2012
Aim: Ventilation with pure oxygen (hyperoxic ventilation: HV) is thought to decrease whole body oxygen consumption (VO(2)). However, the validity and impact of this phenomenon remain ambiguous; until now, under hyperoxic conditions, VO(2) has only been ...

Contribution of anaerobic energy expenditure to whole body thermogenesis

open access: yesNutrition & Metabolism, 2005
Heat production serves as the standard measurement for the determination of energy expenditure and efficiency in animals. Estimations of metabolic heat production have traditionally focused on gas exchange (oxygen uptake and carbon dioxide production ...

Metabolic and cardiorespiratory effects of decreasing lung hyperinflation with budesonide/formoterol in COPD: a randomized, double-crossover, placebo-controlled, multicenter trial

open access: yesRespiratory Research, 2020
Background Studies suggest that acute decreases in lung hyperinflation at rest improves cardiac function and increases lung vascular perfusion from decompression of a compromised heart.
