(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.

(20) In recent studies, we have found that Gal alpha 1----3Gal beta 1----4GlcNAc residues are abundant on red cells and nucleated cells of nonprimate mammals, prosimians, and New World monkeys, but their expression is diminished in Old World monkeys, apes, and humans.
Ovule
Definition:
(n.) The rudiment of a seed. It grows from a placenta, and consists of a soft nucleus within two delicate coatings. The attached base of the ovule is the hilum, the coatings are united with the nucleus at the chalaza, and their minute orifice is the foramen.
(n.) An ovum.
Example Sentences:
(1) Eight-week-old virgin untreated female mice were induced to ovulate using equine chorionic gonadotropin (eCG) and human chorionic gonadotropin (hCG), and were then caged with males overnight.

(3) GnRH infusion produced an immediate increase in plasma LH concentrations in the mares that ovulated during the infusion period and LH levels peaked at the time of ovulation.
(4) An experimental model was established in the ewe allowing one to predict with accuracy an antral follicle that coincidentally would either undergo ovulation (6-8 mm diameter) or atresia (3-4 mm diameter) following synchronization of luteal regression and the onset of the gonadotropin surge.
