Mitochondrial involvement in cold acclimation
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1971Abstract 1. 1. Phospholipid composition and the mitochondrial area of skeletal muscle of three species of mice were determined. 2. 2. Chemical, enzymatic and planimetric measurement demonstrated a direct relationship between the ability of an animal to withstand cold stress and the mitochondrial area. 3. 3.

Acclimation, shock and hardening in the cold
Journal of Thermal Biology, 2005Abstract Recent articles by Bowler [2005. J. Therm. Biol. 30, 125–130] and Loeschcke and Sorensen [2005. J. Therm. Biol. 30, 255–257] have discussed the relationship between acclimation, hardening and heat shock in ectothermic animals, implying that analogous processes occur at low temperatures.

Cold acclimation and cognitive performance: A review
Autonomic Neuroscience, 2017Athletes, occupational workers, and military personnel experience cold temperatures through cold air exposure or cold water immersion, both of which impair cognitive performance. Prior work has shown that neurophysiological pathways may be sensitive to the effects of temperature acclimation and, therefore, cold acclimation may be a potential strategy ...

CIRCULATORY CHANGES IN COLD-ACCLIMATION AND COLD STRESS
Clinical and Experimental Pharmacology and Physiology, 19761. The cardiovascular changes of conscious cold-acclimated (CA) and warm-acclimated (WA) rats during exposure to 5 degrees C or 28 degrees C were studied. 2. The cardiac output, heart rate and stroke volume of Ca rats exposed to 5 degrees C and of WA rats during cold stress were significantly greater, and their calculated total peripheral resistance ...

LIPID METABOLISM IN WARM-ACCLIMATED AND COLD-ACCLIMATED RATS EXPOSED TO COLD
Canadian Journal of Physiology and Pharmacology, 1965The turnover of triglycerides and phospholipids of various tissues was studied in warm-acclimated and cold-acclimated rats, exposed to either a cold or a warm environment, by injecting glucose-U-C14intraperitoneally and measuring its incorporation into glycerol, glycerophosphate, and fatty acid portions of triglycerides and phospholipids at various ...

Lowered cold tolerance in cold-acclimated and non-acclimated guinea pigs treated with diazepam
Zeitschrift für Rechtsmedizin, 1984The effects of the clinically most commonly used minor tranquilizer, diazepam, on the survival time and on the mechanism of death in non-acclimated and cold-acclimated guinea pigs in severe cold exposure (-20 degrees C) were studied. Cold acclimation for 2 months increased the average survival time from 4 h to 10 h.

Cold-acclimation improves cold-tolerance of diabetic rats
Comparative Biochemistry and Physiology Part A: Physiology, 19871. The aim of these experiments was to study the extent to which previous cold-acclimation improves the cold-tolerance of diabetic rats. 2. Alloxan diabetic rats (fasting blood glucose higher than 200 mg/dl) were used in the experiments. 3. In Expt. 1, non-cold-acclimated control and diabetic rats were exposed to cold environment (7-9 degrees C), and ...

METABOLISM OF CARNITINE IN COLD-ACCLIMATED RATS
Canadian Journal of Biochemistry, 1965The body pool, half-life, and turnover time of carnitine in rats maintained at 25 °C and in rats exposed to 5 °C for a period of 6 weeks were measured. The level of free and lipid-bound carnitine in striated muscle of these animals was also determined.Results show that the body pool of carnitine is eight times greater in cold-acclimated rats than in ...

STUDIES ON THERMOGENESIS IN COLD-ACCLIMATED BIRDS
Canadian Journal of Biochemistry and Physiology, 1963Effects on oxygen consumption of continuous intravenous injection of various doses of L-noradrenaline were measured in anesthetized chickens acclimated to 1 °C for 3 months, and in controls. No effects were produced in either and it is concluded that noradrenaline is not a calorigenic mediator in cold-acclimated chickens.

In zones with a seasonal climate, plants undergo periodic transition from a lower to a higher level of resistance. All categories of frost resistance are affected, the tolerance to equilibrium freezing (Fig. 5.1) as well as the ability to undergo deep supercooling (Fig. 5.2).
