Molecular Mechanisms of Parturition
The initial signal for triggering human parturition might be fetal but of trophoblastic origin. Concomitantly, this placental signal would have as its target not only the uterus but also the fetus by activating its hypothalamo-pituitary-adrenocortical axis. The latter would represent a second fetal signal which, at the fetomaternal interface, would amplify and define in time the mechanisms resp...
متن کاملMolecular Mechanisms of Recurrent Pregnancy Loss
Introduction: Pregnancy and health is the process in which the egg is fertilized and being able to survive. When pregnancy occurs under some conditions and the fetus is being at risk, it will lead to abortion that occurs involuntarily and spontaneously. Abortions that occur more than two or three times are called recurrent pregnancy loss (RPL). Various etiological factors involved in RPL, inclu...
متن کاملMolecular Regulation of Parturition: A Myometrial Perspective.
The molecular mechanisms that maintain quiescence of the myometrium throughout most of pregnancy and promote its transformation to a highly coordinated contractile unit culminating in labor are complex and intertwined. During pregnancy, progesterone (P4) produced by the placenta and/or ovary serves a dominant role in maintaining myometrial quiescence by blocking proinflammatory response pathway...
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 کاملO-8: Molecular Mechanisms of Membrane Fusion Involved in Fertilization
Background: Assisted fertilization procedures are a currently widespread practice to regulate reproduction in humans and animals. The arising question is why the human being manipulating gametes to generate new individuals, if we do not understand yet the molecular mechanism of fertilization?. Successful completion of fertilization in mammals is dependent on three membrane fusion events: 1. the...
