(1) Acclimation to 10 degrees C or 30 degrees C resulted in large differences in the dimensions of villi.
(2) Therefore, the hypothesis of a fetal sensori-neural hearing loss due to oxygen lack was tested in the following animal models: a) Adult cats to which feline red blood cells were infused thus causing a polycythemia similar to fetal conditions; b) Adult rats acclimated to altitude in a hypobaric chamber, inducing erythropoiesis with elevated hematocrit and hemoglobin; c) Neonatal guinea pigs and goats studied when they were less than 12 hours old so that the fetal compensatory mechanisms were still present.
(3) Thermogenic response to noradrenaline was markedly increased in cold-acclimated brown adipocytes, while it was reduced in heat-acclimated ones.
(4) Adult males acclimated to an LD 14:10 photoperiod were distributed in five experimental groups: intact controls (NO), sham-pinealectomized (S), sham-pinealectomized with black plastic shielding of the pineal region, pinealectomized (PX), and pinealectomized with the operated region shielded.
(5) In the cold-acclimated rats acute cold exposure increased k as well as turnover rate, but not acute immobilization stress.
(6) No or only a slight increase in sweating activity was observed following the acclimation procedures with face fanning, whereas similar procedures without face fanning had resulted in substantial enhancement of sweating activity in most of the cases, which had been attributed mainly to adaptive changes in central sudomotor activity (as indicated by a shift of the regression line relating Fsw to Tb).
(7) G. cahawbensis cytosol malate dehydrogenase activity increased significantly with increasing acclimation temperature, while G. cochliaris malate dehydrogenase activity remained unchanged.
(8) In hypoxia-acclimated guinea pigs, specific VE was 30% higher than that of control animals due to an elevation in VT; however, VO2 was similar in both groups of animals.
(9) The results of these experiments suggest that the enhanced cold-tolerance of diabetic cold-acclimated rats could be related to the increased sympathetic activity and enhanced insulin sensitivity in thermogenic tissues, such as brown fat.
(10) This species preferred a higher temperature than its acclimation temperature for those acclimation temperatures ranging from 6 degrees to 26 degrees C. When acclimated to 30 degrees and 33 degrees C, the crayfish preferred a lower temperature than its acclimation temperature.
(11) It was suggested that the extent of participation of these factors was not necessarily the same between the cold-acclimated and the stressed organisms.
(12) Maximal response in total epididymal fat cells to noradrenaline was increased in cold acclimation and not changed in heat acclimation at increased numbers of adipocytes in both cold-acclimated and heat-acclimated animals.
(13) NA-induced increase in the plasma NEFA level was less in extent in cold-acclimated rats than in warm-adapted ones.
(14) The role of the rabbit's ear in cold acclimation was studied by varying the temperature of a climatic room in the range from -10 to +30 degrees C; The skin temperature in a nonanesthetized rabbit's ear showed a characteristic response to changes in ambient temperatures; plotting the ear temperature against the ambient temperature yielded an S-shaped curve.
(15) In accordance with data taken from literature, this finding suggests a compensatory enhancement of in vivo protein synthesis to occur in trout during cold acclimation.
(16) To investigate the role of neurohumoral factors in acclimation of mussel muscle to a lowered salinity, studies have been made on the reaction of the intact mussel muscle and that of isolated muscle to change in the salinity from 26% to 10%.
(17) Lugworms, Arenicola marina (L.), acclimatized at 16-17 degrees C, were acclimated at temperatures between 5.3 and 25.7 degrees C for 96 h. Whereas in vitro Arenicola blood behaves like a Rosenthal system, in vivo prebranchial blood does not: the higher the acclimation temperature, the lower the pHv and [HCO3]V, PVCO2, remaining practically constant.
(18) In acclimated dehydrated rats, CO distribution to thermoregulatory areas did not change while perfusion of the splanchnic area decreased.
(19) In the hamster, heat acclimation reduces liver weight more than it does body weight.
(20) The above findings suggest that skeletal muscle Mb may be partly involved in an enhanced thermogenesis in cold acclimation by favouring an oxidative capacity of muscles.
Backwoodsman
Definition:
(n.) A man living in the forest in or beyond the new settlements, especially on the western frontiers of the older portions of the United States.
Example Sentences:
(1) In particular, it settled on a character named Harlan DeGroat, played by Woody Harrelson, depicted as a sociopathic backwoodsman who takes part in bare knuckle fights up in the mountains.
(2) Nonetheless, it is striking that Chippenham is being fought not by any old Tory backwoodsman out of the pages of Horse & Hound , but by Wilfred Emmanuel-Jones , the self-appointed "black farmer" turned would-be MP.
