Cold acclimation in eucalypt hybrids
Tree Physiology, 1994We evaluated cold resistance and the capacity for cold acclimation of different Eucalyptus genotypes. Seedlings of half-sib families of E. globulus and hybrids E. gunnii x globulus, E. viminalis x globulus and E. cypellocarpa x globulus were exposed daily for 56 days to a 9-h photoperiod at 14.7 degrees C, followed by 15 h in a dark cold room ...

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 ...

Proteome Analysis of Cold Acclimation in Sunflower
Journal of Proteome Research, 2011Cold acclimation is the phenomenon in which plants are exposed to low, but nonfreezing, temperatures before exposure to drastic temperatures. To investigate how sunflower plants adjust their metabolism during cold treatment, a comparative proteomic approach, based on spectral counting data, was adopted to identify differentially expressed proteins in ...

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 ...

Regulation of Cold Acclimation
1997Exposure to low, non-freezing temperatures induces molecular, morphological, and physiological changes in plants which result in the acquisition of freezing tolerance (Va-sil’yev, 1961; Guy, 1990; Thomashow, 1993; Hughes and Dunn, 1996). Light, through the process of photosynthesis, provides the energy required for the complex metabolic changes of cold
