From conception to recruitment: Nutritional condition of the dam dictates the likelihood of success in a temperate ungulate

Frontiers in Ecology and Evolution, 2023
Maternal effects are the influence of maternal phenotype and the maternally-provided environment on the phenotype (i.e., expression of traits) of offspring. Frequently, maternal effects are manifest both before and after parturition.

Imbalances between matrix metalloproteinases (MMPs) and tissue inhibitor of metalloproteinases (TIMPs) in maternal serum during preterm labor [PDF]

, 2012
Background: Matrix metalloproteinases (MMPs) are involved in remodeling of the extracellular matrix (ECM) during pregnancy and parturition. Aberrant ECM degradation by MMPs or an imbalance between MMPs and their tissue inhibitors (TIMPs) have been ...

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.

Performance of lactating sows according to parturition order

Boletim de Indústria Animal, 2016
The objective of this study was to evaluate the influence of parturition order on the productive performance of lactating sows. In a completely randomized design, 200 lactating cows were allocated to four treatments: 1st and 2nd, 3rd to 5th, 6th and 7th ...

Deep Investigating the Changes of Gut Microbiome and Its Correlation With the Shifts of Host Serum Metabolome Around Parturition in Sows

Frontiers in Microbiology, 2021
Parturition is a crucial event in the sow reproduction cycle, which accompanies by a series of physiological changes, including sex hormones, metabolism, and immunity.

Expression of C–C motif chemokines and their receptors in bovine placentomes at spontaneous and induced parturition

The Journal of Reproduction and Development, 2019
In bovine placentomes, the inflammatory response is considered important for the detachment of the fetal membrane from the caruncle after parturition. Glucocorticoids, a trigger of the onset of parturition, facilitate functional maturation of placentomes

Deciphering a critical role of uterine epithelial SHP2 in parturition initiation at single cell resolution

Nature Communications, 2023
The timely onset of female parturition is a critical determinant for pregnancy success. The highly heterogenous maternal decidua has been increasingly recognized as a vital factor in setting the timing of labor.

Lactobacillus crispatus S-layer proteins modulate innate immune response and inflammation in the lower female reproductive tract

Nature Communications
Lactobacillus species dominance of the vaginal microbiome is a hallmark of vaginal health. Pathogen displacement of vaginal lactobacilli drives innate immune activation and mucosal barrier disruption, increasing the risks of STI acquisition and, in ...

Programmed Fetal Membrane Senescence and Exosome-Mediated Signaling: A Mechanism Associated With Timing of Human Parturition

Frontiers in Endocrinology, 2017
Human parturition is an inflammatory process that involves both fetal and maternal compartments. The precise immune cell interactions have not been well delineated in human uterine tissues during parturition, but insights into human labor initiation have
