Biological Reviews, 1965
SummarySince 1953 laboratory mice have been bred continuously in an environment kept at – 3° C. Control stocks are kept at 21° C. All mice have cotton wool bedding. The effects of the cold environment are reviewed, and related to observations on other species exposed to cold.Physiological adaptationThe principal physiological adaptation, of a small ...

Trends in Biotechnology, 1997
It is an article of faith among biochemists and molecular biologists that precious enzymes must be stored on ice. The usual reason given is that, at temperatures around freezing, enzyme activity is minimized and protein stability maximized. There is considerable evidence supporting this, but is it true for all enzymes? What about enzymes from organisms

Cold-adapted influenza vaccines
Current Opinion in Pediatrics, 2002Because of the health impact of complicated disease from influenza in children, the role played by children in spreading influenza, and the limitations of inactivated influenza vaccine in this population, there has been ongoing effort to identify a more effective and acceptable vaccine.

Importance of noradrenaline in cold adaptation
American Journal of Physiology-Legacy Content, 1964Noradrenaline (300 µg/kg) was injected daily for 45 days in a group of 15 rats. At the end of this period O2 consumption and rectal temperature responses to noradrenaline (200 µg/kg) were measured at 30 C in these animals as well as in cold-acclimated and control groups.

Cold-adaptation of human rotavirus
Virus Research, 1987A human rotavirus strain was cold-adapted for possible future use as a live vaccine. The original strain was isolated in 1980 in primary cynomolgus monkey kidney cells and has a serotype I and subgroup II antigenicity. The virus was serially passaged in African green monkey kidney cells; it was cultivated at 37 degrees C at the first stage of passages,

Glycogen and nonspecific adaptation to cold
Journal of Applied Physiology, 1981Exposure to moderate cold for a few weeks causes adaptation through the development of nonshivering thermogenesis primarily in the brown adipose tissue. Exposure to severe cold by repeated short exposures also causes adaptation but by mechanisms that seem to be different. These latter results were confirmed in mice. It was also found that this type of

Cold adaptation in marine organisms
Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1990Abstract Animals from polar seas exhibit numerous so called resistance adaptations that serve to maintain homeostasis at low temperature and prevent lethal freezing injury. Specialization to temperatures at or below 0 °C is associated with an inability to survive at temperatures above 3-8 °C.

Cold Adaptation of Triosephosphate Isomerase
Biochemistry, 2017The main problem for enzymes from psychrophilic species, which need to work near the freezing point of liquid water, is the exponential decay of reaction rates as the temperature is decreased. Cold-adapted enzymes have solved this problem by shifting the activation enthalpy-entropy balance for the catalyzed reaction compared to those of their ...
