Stromal cells-specific retinoic acid determines parturition timing at single-cell and spatial-temporal resolution

iScience, 2023
Summary: The underlying mechanisms governing parturition remain largely elusive due to limited knowledge of parturition preparation and initiation. Accumulated evidences indicate that maternal decidua plays a critical role in parturition initiation.

Change of Ruminoreticular Temperature and Body Activity before and after Parturition in Hanwoo (Bos taurus coreanae) Cows

Sensors, 2021
How do body temperature and activity change before and after parturition in pregnant cows? Changes in body temperature such as ruminal, rectal, and vaginal temperature during the parturition have been reported, but there are no results of the ...

Differential Response of Gestational Tissues to TLR3 Viral Priming Prior to Exposure to Bacterial TLR2 and TLR2/6 Agonists

Frontiers in Immunology, 2020
Background: Infection/inflammation is an important causal factor in spontaneous preterm birth (sPTB). Most mechanistic studies have concentrated on the role of bacteria, with limited focus on the role of viruses in sPTB.

Effect of different litter size on the rate of postpartum uterine involution in hu sheep [PDF]

Kafkas Universitesi Veteriner Fakültesi Dergisi, 2022
In this study, we investigated the eff ects of diff erent litter sizes on the rate of uterine involution in Hu sheep. Using B-mode ultrasonography, we recorded changes in the uterine horn diameter and the maximum uterine caruncle diameter in 60 ...

Vaginal dysbiosis increases risk of preterm fetal membrane rupture, neonatal sepsis and is exacerbated by erythromycin

BMC Medicine, 2018
Background Preterm prelabour rupture of the fetal membranes (PPROM) precedes 30% of preterm births and is a risk factor for early onset neonatal sepsis. As PPROM is strongly associated with ascending vaginal infection, prophylactic antibiotics are widely

Individual Variation in Parturition Timing within and among Years for a Bat Maternity Colony

Frontiers in Bioscience-Scholar, 2023
Background: In monoestrous species, the timing of reproduction can have important impacts on offspring survival. For heterotherms in temperate areas, parturition timing is constrained by cold weather survival strategies, such as hibernation and torpor ...

Implementing a novel movement-based approach to inferring parturition and neonate caribou calf survival. [PDF]

PLoS ONE, 2018
In ungulates, parturition is correlated with a reduction in movement rate. With advances in movement-based technologies comes an opportunity to develop new techniques to assess reproduction in wild ungulates that are less invasive and reduce biases ...

Impaired placentomal interferon signaling as the possible cause of retained fetal membrane in parturition-induced cows

The Journal of Reproduction and Development, 2021
Although hormonal induction of parturition in cattle results in the successful delivery of healthy calves, the risk of retained fetal membrane is significantly increased. In a previous study, a combination of the long-acting glucocorticoid, triamcinolone

Differences in hormone levels around parturition in Hanwoo cattle (Bos taurus coreanae) following artificial insemination and embryo transfer

Veterinary Medicine and Science, 2022
Background With unique genetic traits, Hanwoo cattle (Bos taurus coreanae) are well‐adapted to the Korean environment. However, their perinatal mortality rate is 2%–3%, which imposes an economic burden.
