Micro-organisms react to a rapid temperature downshift by triggering a physiological response to ensure survival in unfavourable conditions. Adaptation includes changes in membrane composition and in the translation and transcription machineries. The cold shock response leads to a growth block and overall repression of translation; however, there is ...

Adaptation to Cold and Cold Injury
Journal of The Royal Naval Medical Service, 1972Abstract The possibility of acclimatisation to cold is discussed. The normal adaptation and reaction to cold is described both peripherally and generally, together with the pathology and treatment of frostbite.

Adaptation to environmental stresses, such as temperature fluctuation, is essential for the survival of all living organisms. Cellular responses in both prokaryotes and eukaryotes to high temperature include the synthesis of a set of highly conserved proteins known as the heat shock proteins.

Adaptation to Exercise in the Cold
Sports Medicine, 1985The winter athlete has several potential tactics for sustaining body temperature in the face of severe cold. An increase in the intensity of physical activity may be counter-productive because of increased respiratory heat loss, increased air or water movement over the body surface, and a pumping of air or water beneath the clothing.

The number of reports on enzymes from cold adapted organisms has increased significantly over the past years, and reveals that adaptive strategies for functioning at low temperature varies among enzymes. However, the high catalytic efficiency at low temperature seems, for the majority of cold active enzymes, to be accompanied by a reduced thermal ...

Advanced Healthcare Materials
AbstractCold‐adapted nanozymes represent a distinct class of nanomaterials that exhibit robust catalytic activity and stability under low‐temperature conditions (below 37 °C). By emulating the catalytic functions of natural enzymes, these nanozymes can overcome the inherent limitations of traditional enzymes, which typically suffer from the reduced ...

Mechanisms of Adaptation to Cold
International Journal of Sports Medicine, 1992The animal model used the most frequently for understanding the mechanisms of adaptation to cold in humans has been the rat. It has been established that rats kept in the cold for a few weeks stop shivering while preserving a normal internal temperature because of an enhanced thermogenic capacity of the brown adipose tissue (BAT) mediated by the ...

Cold adaptation of microorganisms
Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1990Abstract Psychrophilic and psychrotrophic microorganisms are important in global ecology as a large proportion of our planet is cold (below 5 °C); they are responsible for the spoilage of chilled food and they also have potential uses in low-temperature biotechnological processes.

Nature Reviews Microbiology, 2006
Many archaea are extremophiles. They thrive at high temperatures, at high pressure and in concentrated acidic environments. Nevertheless, the largest proportion and greatest diversity of archaea exist in cold environments. Most of the Earth's biosphere is cold, and archaea represent a significant fraction of the biomass.

Cold-Stable and Cold-Adapted Microtubules
1995Most mammalian microtubules disassemble at low temperature, but some are cold stable. This probably has little to do with a need for cold-stable microtubules, but reflects that certain populations of microtubules must be stabilized for specific functions. There are several routes by which to achieve cold stability.
