Adaptations to extreme conditions

Editorial: Physiology in Extreme Conditions: Adaptations and Unexpected Reactions

“Physiology in extreme conditions” was concerned with two main issues: (a) to increase knowledge about individual reactions and mechanisms of adaptations in specific extreme environmental conditions; (b) to widen the analytical skills gap created by data generated in extremely severe conditions, and in response to pathological disorders. A wide spectrum of topics was proposed by the included ar...

Muscle adaptations in extreme environments

Many environmental factors may affect muscle plasticity but some have exclusive characteristics that allow them to play a key role to maintain the muscle capacity to generate force; these factors are: i) the oxygen availability and ii) the load applied to muscle fibres. Hyperbarism is a condition that occurs when a man is subjected to pressure increases. To keep the lungs from collapsing, the a...

Adaptations of anaerobic archaea to life under extreme energy limitation.

Some anaerobic archaea live on substrates that do not allow the synthesis of 1 mol of ATP per mol of substrate. Energy conservation in these cases is only possible by a chemiosmotic mechanism that involves the generation of an electrochemical ion gradient across the cytoplasmatic membrane that then drives ATP synthesis via an A1AO ATP synthase. The minimal amount of energy required is thus depe...

Modeling Environments: Interactive Causation and Adaptations to Environmental Conditions

Molecular adaptations of lipolysis to physical activity

The purpose of the present study was to investigate the context of lipid metabolism research in physical activity, lipolysis, lipolysis hormone regulation and the fate of lipolysis products in exercise, fatty acid transporters, some genes involved in lipid metabolism, effect of resistance activity on lipolysis, adaptations of adipose tissue due to physical activity, lipoproteins and apoproteins...
