(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.
Organism
Definition:
(n.) Organic structure; organization.
(n.) An organized being; a living body, either vegetable or animal, compozed of different organs or parts with functions which are separate, but mutually dependent, and essential to the life of the individual.
Example Sentences:
(1) The high amino acid levels in the cells suggest that these cells act as inter-organ transporters and reservoirs of amino acids, they have a different role in their handling and metabolism from those of mammals.
(2) These organic compounds were found to be stable on the sorbent tubes for at least seven days.
(3) The main clinical features pertaining to the concept of the "psycho-organic syndrome" (POS) were investigated in a sample of children who suffered from severe craniocerebral trauma.
(4) After 3 and 6 months, blood collected by cardiocentesis using ether anesthesia and then sacrificed to remove CNS and internal organs.
(5) Addition of phospholipase A2 from Vipera russelli venom led to a significant increase in the activity of guanylate cyclase in various rat organs.
(6) For the first time it was organized on the basis of population.
(7) Acceptance of less than ideal donors is ill-advised even though rejection of such donors conflicts with the current shortage of organs.
(8) There is no evidence that health-maintenance organizations reduce admissions in discretionary or "unnecessary" categories; instead, the data suggest lower admission rates across the board.
