Post-Transcriptional Regulation by microRNAS in Pregnancy and Parturition
Throughout most of pregnancy, uterine quiescence is maintained by increased progesterone receptor (PR) transcriptional activity, while spontaneous labor is initiated/facilitated by a concerted series of biochemical events that activate inflammatory pathways and negatively impact PR function. In …

Feto-Maternal Exosome Characterization, Trafficking and Function During Pregnancy and Parturition
Endocrine factors and signals of fetal organ maturation are well-reported determinants of the timing of birth and have been studied extensively in both humans and animal models. However, decades of research have not yielded answers to the timing of labor. It is evident that endocrine factors alone …

The Bony pelvis scars of parturition and factors Influencing their manifestation
… several sites on the pelvis reported to display parturition scarring in a skeletal sample of 391 individuals (230 males and 161 females). The scar features, body and pelvic dimensions were compared according to the sex, age and time period of origin of the individuals. Correlation tests were …

Maintenance of fetal membrane integrity by cyclic cellular transitions during gestation and parturition
Fetal membranes line the intra-uterine cavity and perform protective functions during pregnancy. Rupture of membranes before term is deemed ‘catastrophic’ and contributes to infection, preterm birth, and neonatal death. During gestation, membranes repair and remodel through a balanced …

Initiation of Parturition in Dairy Cows with Dexamethasone and Dexamethasone Plus Estradiol Benzoate
<p>Parturition was initiated in 25 of 29 (Trial 1) and 26 of 26 (Trial 2) Holstein cows given dexamethasone (Trial 1), 4.4 mg/100 kg body weight, or dexamethasone plus .25 mg estradiol benzoate (Trial 2) at day 273 of gestation. Parturition occurred at 45.l z +/-11.1 h (Trial 1) and 40.8 ± 9.6 h …

Pregnancy and parturition in rats on a zinc deficient diet with varying levels of tryptophan
… 6 and 9 ppm were not sufficient for normal parturition.

Prediction of parturition and dystocia in holstein-friesian cattle, and cesarean section in dystocic beef cattle
… In some instances, human intervention of the parturition process is imperative to avoid pain, injury, and mortality of the neonate and the dam. The ability to accurately predict dystocia and the time of parturition will ensure that timely assistance can be given to animals that are of high …

Relationship between intravenous fluids given to women during parturition and their breastfed newborns' weight loss
… the intravenous (IV) fluids women receive during parturition (the act of giving birth including time in labour or prior to a cesarean section) and their newborn's weight loss during the first 72 hours postpartum was the primary interest. Three hypotheses guided the thesis. Specifically, the …

Consequences of the environment: timing of litter parturition and offspring survival in the social rodent Octodon degus
Variation in the timing of offspring parturition determines the environmental factors they experience during early development and their likelihood for survival. I used an 11-year dataset on a natural, free-living population of degus (Octodon degus), a social rodent endemic to Chile, to test …

The relationship between nitric oxide synthase (NOS) and cyclooxygenase (COX) in the control of cervical ripening and parturition
… COX-2 in the control of cervical ripening and parturition. Cervices were obtained from estrus and timed pregnant Sprague-Dawley rats (n = 4-10 per group) under normal conditions; or after treating with LPS (100ƒÝg i.p.), Onapristone (3mg/rat), progesterone (2.5 mg, twice daily), L-NAME …

The Influence of Season on Estrus, Ovulation, and Reproductive Hormone Secretions in Barren and Periparturient Pony Mares (Postpartum, Adrenal, Parturition)
An extended study was done to determine reproductive and hormonal parameters in pony mares during the peripartum period over three seasons: winter, summer and fall. Experiments were also conducted on control and hormonally manipulated barren mares during the same three seasons.

Metabolic, reproductive, and performance evaluation in primiparous Nellore beef cows under grazing with different ages at breeding
… samples were taken on the average 15 days before parturition, and on days 30, 60, 120, 240 days postpartum to measure glucose, total proteins, albumin, urea, beta-hydroxybutyrate (β-OHB) and non-esterified fatty acids (NEFA), progesterone at 30 and 45 postpartum and for insulin-like growth …
