2. Crayfish tissues responded to cold exposure within 5-7 days by upregulating the mRNA (determined through real-time polymerase chain reaction Vemurafenib purchase (PCR)) for both PMCA and NCX. After 28 days, levels were 4-5 x higher in antennal gland and 2-3 x higher in Muscle. fit situ hybridization localized the

mRNA increase to the nephridial canal in antennal gland sections and to the extensor muscles in the tail. Western blotting confirmed corresponding increases in PMCA protein expression. however, expression of NCX protein was unchanged. (C) 2009 Elsevier Ltd. All rights reserved.”
“The experiment was carried out with the aim of investigating the effect of ascorbic acid (AA) on fluctuations in rectal temperature (RT) of pigs during the harmattan season. Sixteen pigs administered with AA at the dose of 250 mg/kg orally and individually served as experimental animals, and 13 others

GSK461364 administered orally with sterile water were used as control animals. The RT was measured from all the pigs at 06:00, 13:00 and 18:00 h twice in a week for three consecutive Weeks. The lowest overall mean RT Value of 37.52 +/- 0.90 C was obtained at 06:00 h in the experimental pigs, while the corresponding Value in control pigs was 37.63 +/- 0.90 C (P>0.05). The maximum RT values of 38.75 Rebamipide +/- 0.18 C and 39.27 +/- 0.11 C were recorded at 13:00 h in experimental and control pigs, respectively (P<0.05). The results indicate that AA modulates the body temperature by decreasing the maximum RT Value in pigs exposed to harmattan stress, and may alleviate

the risk of adverse effects of the stress on health and productivity of pigs during the cold-dry season. (C) 2009 Published by Elsevier Ltd.”
“We measured body temperatures in two large hibernating mammals, the eutherian alpine marmot (Marmota marmota) and the egg-laying echidna (Tachyglossus aculeatus) from unrestrained animals in their natural environment. In both species hibernation is broken every 13 days on average by rewarming to euthermic temperatures. We found that the time course of a rewarming Could be closely fitted with a sigmoid curve, allowing calculation of peak rewarming rate and corresponding body temperature. Maximum rewarming rates were twice as high in marmots as in echidnas (12.1 +/- 1.3 degrees C h(-1), n = 10 cf. 6.2 +/- 1.2 degrees C h(-1), n = 10). Peak rewarming rates were positively correlated with body temperature in echidnas, but negatively correlated in marmots. (C) 2009 Elsevier Ltd, All rights reserved.”
