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

open access: yesThe 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

Initiation of human parturition: signaling from senescent fetal tissues via extracellular vesicle mediated paracrine mechanism

open access: yesObstetrics & Gynecology Science, 2019
A better understanding of the underlying mechanisms by which signals from the fetus initiate human parturition is required. Our recent findings support the core hypothesis that oxidative stress (OS) and cellular senescence of the fetal membranes (amnion ...

The role of cellular coupling in the spontaneous generation of electrical activity in uterine tissue [PDF]

open access: yesPLoS ONE 10 (2015) e0118443, 2014
The spontaneous emergence of contraction-inducing electrical activity in the uterus at the beginning of labor remains poorly understood, partly due to the seemingly contradictory observation that isolated uterine cells are not spontaneously active. It is known, however, that the expression of gap junctions increases dramatically in the approach to ...

Novel concepts on pregnancy clocks and alarms: redundancy and synergy in human parturition.

open access: yesHuman Reproduction Update, 2016
The signals and mechanisms that synchronize the timing of human parturition remain a mystery and a better understanding of these processes is essential to avert adverse pregnancy outcomes.

Immune cells and preterm labour:do invariant NKT cells hold the key? [PDF]

open access: yes, 2015
We have developed our original made-to-measure (M2M) algorithm, PRIMAL, with the aim of modelling the Galactic disc from upcoming Gaia data. From a Milky Way like N-body disc galaxy simulation, we have created mock Gaia data using M0III stars as tracers,

Control of parturition in ruminants

open access: yesBioscientifica Proceedings, 2019
Parturition is a process which, when set into motion, occurs to completion. This review concerns the control of parturition in ruminants. Parturition is an endocrine event, dependent upon the activation of the fetal hypothalamus-pituitary-adrenal (HPA ...

Effects of maternal subnutrition during early pregnancy on cow hematological profiles and offspring physiology and vitality in two beef breeds [PDF]

open access: yes, 2019
This experiment evaluated the effects of subnutrition during early gestation on hematology in cows (Bos Taurus) and on hematological, metabolic, endocrine, and vitality parameters in their calves.

Changes in the Th1 : Th2 Cytokine Bias in Pregnancy and the Effects of the Anti-Inflammatory Cyclopentenone Prostaglandin 15-Deoxy-Δ12,14-Prostaglandin J2

open access: yesMediators of Inflammation, 2012
Pregnancy is a complex immunological state in which a bias towards T helper 2 (Th2) protects the fetus. Evidence suggests that proinflammatory cytokines increase the risk of poor neonatal outcome, independently of the direct effect of preterm labour. The

Myometrial Transcriptional Signatures of Human Parturition

open access: yesFrontiers in Genetics, 2019
The process of parturition involves the transformation of the quiescent myometrium (uterine smooth muscle) to the highly contractile laboring state. This is thought to be driven by changes in gene expression in myometrial cells.

Differential effects of steroids and retinoids on bovine myelopoiesis in vitro [PDF]

open access: yes, 2004
Pregnancy and parturition are associated with physiological changes caused by steroid hormones. Alterations in number, maturity, and function of polymorphonuclear leukocytes observed in dairy cows at parturition suggest a common causative relationship ...
