(1) While in the brains of adult homeothermic vertebrates (with thermo-regulation: mammals, birds) the di-sialoganglioside GD1a predominates, in the brain of poikilotherms (without thermo-regulation: e.g.
(2) Thus, whereas a change in central MSH sensitivity may contribute to reduced fever in aged homeotherms, a reduction in central pyrogen receptors appears to be the most parsimonious explanation.
(3) The relationship between body size and basal metabolic rate (BMR) in homeotherms has been treated in the literature primarily by comparison between species of mammals or birds.
(4) Some homeothermic animals can survive adverse conditions by hibernation, i.e., by reducing their body temperature in accordance with ambient temperature, thus reducing metabolism and vital functions.
(5) By extension these findings implicate the Na+ pump as a heat source in the evolution of the homeotherms.
(6) On the 15th day after hatching, chinstrap chicks were completely, and gentoo chicks almost completely, homeothermic.
(7) These results may indicate that the homeothermic metabolic response in late embryos is O2-conductance-limited and power-limited as previously suggested.
(8) For mild cooling (32 degrees C), the Q10 in 18-day-old embryos was about 1.5, while 12- and 16-day-old embryos had a Q10 value of about 2, indicating that a feeble homeothermic metabolic response to cooling appears in late prenatal embryos.
(9) R-band exons in homeotherms but not G-band exons have directionally acquired GC-rich wobble bases and the corresponding codon usage: CpG islands in mammals are specific to R-band exons, exons not facultatively heterochromatinized, and are independent of the tissue expression pattern of the gene.
(10) The carp muscle enzyme was less sensitive to AMP inhibition than the muscle enzyme from a homeothermic mammal.
(11) This observation, when coupled with the experimental results, suggests that the effect of low [K]o on membrane permeability in homeothermic preparations of cardac muscle should be reevaluated.
(12) The hibernation season in the arctic ground squirrel (Citellus undulatus) is broken into 8- to 18- day cycles by short homeothermal periods during which the carboydrate reserves depleted during hibernation are replenished.
(13) The relative susceptibility of rabbit (homeothermic) kidney to mercury intoxication was compared to that of Coho salmon (poikilothermic) kidney to mercury intoxication was compared to that of Coho salmon (poikilothermic) kidney over temperature ranges consistent with the habitat of each of the two species.
(14) We have compared changes in axon numbers in the developing optic nerves of eight homeotherms (seven mammals and one bird) using data from the available literature and our own material.
(15) Phylogenetic data indicate that the complete psysiological and behavioral manifestations of sleep are unique to homeotherms; furthermore "ontogeny recapitulates phylogeny" in the parallel development of slow wave sleep and thermoregulation as exemplified in the opossum.
(16) The adult tapeworm lives in the intestine of a homeothermic host and has a pattern of very active and never ending growth.
(17) Color-coded liquid plastic was injected intraparenchymally (not into the blood vessels) into more than 300 hearts of homeotherms--including dog, cat, sheep, beef, horse, mammalian dolphins, chickens, turkeys, etc.
(18) Increased host resistance to viral and bacterial infections has also been noted in homeotherms whose body temperature has been elevated by manipulation of ambient temperature.
(19) However, the effect of ambient temperature on intestinal transit in homeothermic neonates such as pigs, calves, and humans may be different from that in mice because neonatal mice are poikilothermic.
(20) The spadix of Symplocarpus foetidus L. maintains an internal temperature 15 degrees to 35 degrees C above ambient air temperatures of -15 degrees to +15 degrees C. For at least 14 days it consumes oxygen at a rate comparable to that of homeothermic animals of equivalent size.
Homothermic
Definition:
(a.) Alt. of Homothermous
Example Sentences:
(1) The rainbow trout lens was used as the poikilothermal lens and the rat lens as the homothermal lens.
(2) The rate and form of growth of Histoplasma capsulatum within histiocytes derived from homothermic and poikilothermic animals, and incubated at 25, 30, and 37 C, are described.
(3) In poikilothermic 3-, 10- and homothermic 30-day-old rats ethylmorphine N-demethylation rate was dependent on incubation temperature (7, 20 and 37 degrees C).
(4) The response of the poikilothermal lens to various incubation temperatures in vitro was compared with that of the homothermal lens.
(5) Membrane response to the various temperatures as one of the external factors was investigated in the lenses of the poikilothermal animal and the homothermal animal.
(6) At a prolonged acclimation to cold (up to 3 months, +4 degrees), the thyroid activity increases both in golden hamster, and in homothermal rats.
(7) The rainbow trout lens was used as the poikilothermal material and the rat lens as the homothermal material.
(8) The power of the technique is illustrated by the ability to partially separate the evolutionarily closely related main homothermic species.
(9) Most work has concentrated upon juvenile fish or upon rapidly growing young market fish; these have high protein dietary requirements (30-50%) that are in direct contrast to the homothermic terrestial animals.
(10) This explains wide parasitic links of the tundra vole with other homothermic animals which especially extensive with the bank vole and it may have important consequences for epizootiology of tularemia and tick-borne encephalitis.
