TLDR
The temporal relationship between delta4-androstenedione-induced preterm switching of myometrial activity patterns from contractures to contractions and maternal plasma estradiol and oxytocin concentrations in the 0.8 gestation rhesus monkey is investigated.

Brain preparations for maternity--adaptive changes in behavioral and neuroendocrine systems during pregnancy and lactation. An overview.

John A. Russell, +2 more
- 01 Jan 2001 - 
TL;DR: The part played by oxytocin neurons and their regulatory mechanisms is reviewed to illustrate how neural systems involved in maternity are prepared in pregnancy via changes in phenotype, synaptic organization and in the relative importance of their different inputs, to function optimally when needed.

Neuroendocrine Mechanisms in Pregnancy and Parturition

Felice Petraglia, +2 more
- 01 Dec 2010 - 
TL;DR: Evidence for a premature activation of OT secretion as well as increased maternal plasma CRH levels suggests a pathogenic role of these neurohormones, and placental hypersecretion of CRH or Ucn has been proposed as a predictive marker of subsequent preterm delivery.

Sex, parturition and motherhood without oxytocin?

John A. Russell, +1 more
- 01 Jun 1998 - 
TL;DR: In both types of oxytocin gene disablement, the only evident defect was a complete failure of postpartum homozygotes to transfer milk to the suckling young, which consequently did not survive unless the mothers were treated with exogenous oxytocIn, and these findings are surprising in view of the vast literature on a wide range of species suggesting important roles for oxytoc in regulating gonadal function, in expression of sexual behaviour, in parturition and initiation of maternal behaviour as well as

Steroid hormone control of myometrial contractility and parturition.

Sam Mesiano, +1 more
- 01 Jun 2007 - 
TL;DR: This review addresses current understanding of how progesterone and estrogens affect the contractility of the pregnancy myometrium and how their actions are coordinated and controlled as part of the parturition cascade.

Endocrinology of parturition

Victoria Snegovskikh, +2 more
- 01 Mar 2006 - 
TL;DR: In this paper, the authors reviewed the current understanding of the parturition cascade responsible for spontaneous onset of labor at term and discussed preterm labor and post-term pregnancy, and concluded that preterm birth is associated with significant increase in perinatal morbidity and mortality.

Effect of corticosteroids for fetal maturation on perinatal outcomes, February 28-March 2, 1994

L. C. Gilstrap, +15 more
- 01 Jan 1995 - 
TL;DR: The consensus panel concluded that antenatal corticosteroid therapy for fetal maturation reduces mortality, respiratory distress syndrome, and intraventricular hemorrhage in preterm infants and will result in a substantial decrease in neonatal morbidity and mortality, as well as substantial savings in health care costs.

The mechanism of initiation of parturition in the ewe.

G. C. Liggins, +4 more
- 01 Jan 1973 - 
TL;DR: In this article, the authors discuss the mechanism of initiation of parturition in the ewe and describe a study that has been carried out on sheep to determine the extent to which the lamb shares in the mechanisms of initiation, to elucidate the means of its participation, and to unravel the intricate endocrine relationship between the conceptus and the mother.

- 01 Feb 1990 - 
TL;DR: The basic mechanisms underlying regulation of steroidogenesis within the fetoplacental unit during primate pregnancy appear similar, in important ways, to those of widely used laboratory animals, such as the rat and rabbit.

TL;DR: It is proposed that the co‐ordinating of oxytocin receptor formation, PG synthesis and gap junction formation is a key to the initiation and maintenance of human labour.
