Effect of Relaxin on Parturition in Ruminants
The biology of relaxin differs in many respects between ruminants and nonruminants. Immunoreactive blood concentration of circulating relaxin is much less in ruminant (cattle and sheep) than in nonruminant (pigs) farm animals. The ovaries of the pig produce abundant quantities of the hormone in late pregnancy, whereas tissue sources of relaxin are not clearly defined in sheep and cattle. Relaxi...
متن کاملParturition mechanisms in ruminants: A complete overview
Parturition is the process of delivery of the fully grown fetus on the completion of the normal pregnancy period. Parturition is an interesting biological process in the sense that the uterus that was quiescent during the entire pregnancy starts contracting and the cervix that was tightly contracted relax sufficiently to allow the passage of the young one to the world outside the mother’s womb,...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولRelaxin and the control of primate parturition.
In primate pregnancy, circulating relaxin, solely a product of the corpus luteum, peaks in the first trimester of pregnancy then declines and levels off for the remainder of pregnancy. Relaxin actions in pregnancy include increasing cervical pro-MMP-1 and pro-MMP-3 and decreasing TIMP-1, changes which soften the cervix. Relaxin, from early pregnancy, increases endometrial natural killer cells, ...
متن کاملHormonal control of glucose homoeostasis in ruminants.
Little, if any, glucose is absorbed from the alimentary tract of the grazing ruminant and it appears that significant absorption of glucose only occurs in ruminants consuming relatively large amounts of grain (Bergman, 1973 ; Lindsay, 1978). In spite of this, ruminants have an absolute requirement for glucose which is similar to that of nonruminants. Certainly glucose is an essential metabolite...
