(15) Based on the fact that all hibernators, at their regulated minimal body temperature, display a uniform turnover rate, related to body weight, the hypothesis is developed that cold tolerance of mammals is generally limited by a common specific minimal metabolic rate, which larger organisms, because of their lower basal metabolism, already attain in less profound hypothermia.
(16) Based on morphological, virological, biochemical and molecular biological data, it is proposed that the presence of endogenous retrovirus particles in the placental cytotrophoblasts of many mammals is indicative of some beneficial action provided by the virus in relation to cell fusion, syncytiotrophoblast formation and the creation of the placenta.

Pika
Definition:
(n.) Any one of several species of rodents of the genus Lagomys, resembling small tailless rabbits. They inhabit the high mountains of Asia and America. Called also calling hare, and crying hare. See Chief hare.
Example Sentences:
(1) In contrast, while gastric ulcers in the rat formed within a short time, they were histopathologically less severe than those in the pika.
(2) Therefore, the antagonism of phenoperidine action by morphine appeared not to occur at the opiate receptor site; the mechanism of the pika's natural tolerance to morphine may reside in molecular events that normally preceed (metabolism?)
