Allopregnanolone alters follicular and luteal dynamics during the estrous cycle
(BioMed Central, 2018-04)
Background: Allopregnanolone is a neurosteroid synthesized in the central nervous system independently of steroidogenic glands; it influences sexual behavior and anxiety. The aim of this work is to evaluate the indirect ...
Atuação do interferon-tau no reconhecimento materno da gestação
(2014)
Maternal recognition of pregnancy is a process by which the conceptus signals its presence to the mother in order to prolong the life of the corpus luteum (CL) thus maintaining the pregnancy. This process occurs between ...

Expression of fibroblast growth factor 22 (FGF22) and its receptor, FGFR1B, during development and regression of bovine corpus luteum
(Elsevier B.V., 2019-02-01)
The aim of this study was to determine the expression of fibroblast growth factor 22 (FGF22) in the bovine corpus luteum (CL) and to investigate the effects of in vivo total or partial cloprostenol-induced luteolysis on ...
Efficacy of induction of luteolysis in superovulated cows is dependent on time of prostaglandin F2alpha analog treatment: effects on plasma progesterone and luteinizing hormone profiles.

Functional luteolysis in response to hydrogen peroxide in human luteal cells
(BioScientifica Ltd., 1995)
To evaluate the effect of reactive oxygen species in human corpus luteum function, we investigated whether hydrogen peroxide (H2O2) affects the in vitro luteal cell production of steroids. H2O2 treatment (1.0-100 μM) of ...
Plasma PGFM and progesterone concentrations, luteolysis moment and estrous cycle length in Nelore cows submitted to uterine biopsies
(2015-01-01)
In this study, endometrial samples were collected in 14 Nelore cows on days zero (ovulation), five, nine, thirteen and nineteen of the estrous cycle (biopsy group), and in 15 females these collections weren't performed ...
Hemodynamics of the corpus luteum in mares during experimentally impaired luteogenesis and partial luteolysis
(2018-02-01)
The aim of the current project was to characterize the luteal vascularity and the plasma concentrations of progesterone (P4), prolactin (PRL) and 13,14-dihydro-15-keto-PGF2α (PGFM) in mares with luteal disturbances during ...
