Polymorphisms in VEGF, progesterone receptor and IL-1 receptor genes in women with recurrent spontaneous abortion
(Elsevier B.V., 2011-01-01)
Hormonal, inflammatory and vascular alterations during pregnancy are thought to be involved in pregnancy loss. the role of progesterone, the actions of which involve cytokines and vascular endothelial growth factor (VEGF), ...
A Cellular and Endocrine Characterization of the Original and Induced Corpus Luteum after Administration of a Gonadotropin-Releasing Hormone Agonist or Human Chorionic Gonadotropin on Day Five of the Estrous Cycle
(1996-01-01)
To determine whether injection of hCG or GnRH-agonist on d 5 after estrus (d 0) has a differential functional effect on an induced and the original corpus luteum (CL), two experiments were conducted. In Exp. 1, nonlactating ...
Effects of concanavalin A on the progesterone production by bovine steroidogenic luteal cells in vitro
(2016-10-01)
The aim of this study was to evaluate the effects of concanavalin A (CONA) on the progesterone (P4) production by bovine steroidogenic luteal cells (LCs) in vitro. Luteal cells were collected during the mid-luteal stage ...
Can blood progesterone concentration identify non-pregnant buffaloes to support oestrous resynchronization?
(2022-01-01)
This study compared the plasma progesterone concentrations from pregnant and non-pregnant buffaloes to identify non-pregnant females and submit cows earlier to oestrous resynchronization. Forty-four multiparous mix-breed ...
Metabolismo hepático e sua influência no desempenho reprodutivo em bovinos
(Universidade Federal de Santa MariaBrasilMedicina VeterináriaUFSMPrograma de Pós-Graduação em Medicina VeterináriaCentro de Ciências Rurais, 2020-02-21)
Reproductive efficiency is the parameter that most affects the productivity and profitability of beef and dairy cattle production systems, and most gestational losses occur early during the first trimester of gestation. ...
In utero and lactational exposure to triclocarban: reproductive effects on female rat offspring
(Wiley-Blackwell, 2019-12-23)
Triclocarban (TCC) is an antimicrobial compound widely used in personal care products such as soaps, toothpaste, and shampoo. This agent is incompletely removed by wastewater treatment and represents an environmental ...
Elevated progesterone concentrations enhance prostaglandin F-2 alpha synthesis in dairy cows
(Elsevier B.V., 2009-08-01)
The objective was to evaluate the influence of varying plasma progesterone (P-4) concentrations throughout the luteal phase in dairy cows on PGF(2 alpha) production (assessed as plasma concentrations of 13,14-dihydro-15-keto-PGF(2 ...
Bone morphogenetic protein 15 supplementation enhances cumulus expansion, nuclear maturation and progesterone production of in vitro-matured bovine cumulus-oocyte complexes
(Wiley-Blackwell, 2021-03-08)
In vitro embryo production (IVP) efficiency is reduced when compared to in vivo. The basic knowledge of bovine in vitro oocyte maturation (IVM) mechanisms provides support to improve in vitro embryo production yields. The ...
Progesterone and VIP cross-talk enhances phagocytosis and anti-inflammatory profile in trophoblast-derived cells
(Elsevier Ireland, 2017-03)
Trophoblast cells produce several inmmuneregulators like the Vasoactive Intestinal Peptide (VIP) and P4 targeting multiple circuits, and also display an intese phagocytic ability allowing embryo implantation in a tolerogenic ...
