Extensive prokaryotic maintenance respiration in the sea influenced by osmoregulation

Frontiers in Marine Science, 2023
Microbial respiration is the major process consuming oxygen in the biosphere. The relative energy demand from growth of biomass or maintenance activities determines the regulation of respiration with impact on how the development of hypoxia and CO2 ...

Metabolic profiling of hypoxic cells revealed a catabolic signature required for cell survival [PDF]

, 2011
Hypoxia is one of the features of poorly vascularised areas of solid tumours but cancer cells can survive in these areas despite the low oxygen tension.

Association between Fractional Oxygen Extraction from Resting Quadriceps Muscle and Body Composition in Healthy Men

Journal of Functional Morphology and Kinesiology, 2023
This study aimed to associate body composition with fractional oxygen extraction at rest in healthy adult men. Fourteen healthy adults (26.93 ± 2.49 years) from Chile participated.

THE RESPIRATION OF GROWING PLANT CELLS [PDF]

Plant Physiology, 1945
Growing cells of the hypocotyl of Helianthus seedlings were used, employing conditions identical with those of previous experiments cited above. The uppermost thirty-five millimeters of hypocotyl were cut in seven segments of uniform length (5 mm.). The region in which the cells were embryonic was not more than one millimeter long.

ND3 Cys39 in complex I is exposed during mitochondrial respiration [PDF]

, 2022
Mammalian complex I can adopt catalytically active (A-) or deactive (D-) states. A defining feature of the reversible transition between these two defined states is thought to be exposure of the ND3 subunit Cys39 residue in the D-state and its occlusion ...

Adhesion Forces of Oral Bacteria to Titanium and the Correlation with Biophysical Cellular Characteristics

Bioengineering, 2022
Bacterial adhesion to dental implants is the onset for the development of pathological biofilms. Reliable characterization of this initial process is the basis towards the development of anti-biofilm strategies.

The Warburg effect suppresses oxidative stress induced apoptosis in a yeast model for cancer. [PDF]

PLoS ONE, 2009
BACKGROUND: Otto Warburg observed that cancer cells are often characterized by intense glycolysis in the presence of oxygen and a concomitant decrease in mitochondrial respiration.

Effect of Antibiotics on Respiration in Human Cells [PDF]

Pediatric Research, 1972
Extract: Chloramphenicol (CAP), chloramphenicol succinate (CAP-S), tetracycline (TET), and erythromycin (EM) inhibited synthesis of a mitochondrial enzyme, cytochrome oxidase, in cultured human fibroblasts; the 50% inhibitory concentrations were 7.5, 13, 18, and 350 $mUM respectively, or 2.4, 4.1, 8, and 250 $mUg/ml.

Plastron Respiration Using Commercial Fabrics [PDF]

, 2014
A variety of insect and arachnid species are able to remain submerged in water indefinitely using plastron respiration. A plastron is a surface-retained film of air produced by surface morphology that acts as an oxygen-carbon dioxide exchange surface ...
