The phrase "activation of parturition" is correct and usable in written English.
It can be used in medical or biological contexts, particularly when discussing the process of childbirth or the initiation of labor.
Example: "The activation of parturition is a complex process involving hormonal changes and uterine contractions."
Alternatives: "induction of labor" or "initiation of childbirth."
Change in transvaginal cervical length over time may reflect early activation of the parturition process, as has been demonstrated in singleton pregnancies.
Despite medical advances and better understanding of uterine activation and parturition, the rates of PTB have been increasing over the past three decades in developed countries [ 3]. with current rates ranging from 5-75-7%4]. and also complicate 9.6% of all births worldwide [ 5].
This common pathway of parturition involves the activation of various physiological processes including myometrial contraction, decidual activation, membrane extracellular matrix degradation, weakening and rupture and cervical ripening resulting in labor and delivery [ 37, 48].
Such a pronounced effect of PROK1 on immune pathways suggests that PROK1 may regulate recruitment of leukocytes to the myometrium at term and their activation and, thus, contributes to the initiation of parturition.
However, it is plausible that maternal psychological and/or physical stress, which are known to be associated with adverse lifestyle factors, may promote activation of neuroendocrine or proinflammatory pathways in favour of parturition.
Phase 2 is a progressive cascade of events leading to a common pathway of parturition involving high amplitude, regular uterine contractions, cervical ripening, and activation of the decidua and fetal membranes.
One fundamental difference between the spontaneous parturition at term and preterm labor is that term labor results from physiological activation of components of the common pathway, while preterm labor arises from pathological processes that activate one or more of the components of the common pathway of parturition.
In the sheep parturition is initiated by activation of the fetal pituitary-adrenal axis [ 8], with increased fetal cortisol secretion [ 9], followed by the activation of placental cytochrome P450 (CYP17A family) enzymes with 17α hydroxylase and 17 20 lyase activities [ 10].
Eliot sometimes referred to her books as her children, and the writing of them as a form of parturition.
One indicator of the onset of parturition is a decrease in the doe's blood progesterone level approximately 24 30 h prior to parturition.
