Unravelling the role of 17β-estradiol on advancing uterine luteolytic cascade in cattle
(2022-01-01)
In cattle, 17β-estradiol (E2) stimulates prostaglandin F2α (PGF2α) synthesis, which causes luteolysis. Except for the well-established upregulation of oxytocin receptor gene (OXTR), molecular mechanisms of E2-induced PGF2α ...
Effects of ethanol on synthesis of prostaglandin F2α in bovine females
(Berlin, 2010)
Ethanol stimulates the production of prostaglandins in many species. The purpose of this study was to verify the effect of ethanol on the production of prostaglandin F2α (PGF2α) and luteolysis in bovine females. In the ...
Avaliação da taxa de prenhez em novilhas tratadas com protocolo GnRH-PGF2'alfa' -Benzoato de Estradiol (GPE) e em vacas submetidas a tratamentos hormonais com progesterona associados ou não a remoção temporária de bezerros
(Universidade Estadual Paulista (Unesp), 2003)
A curta duração do estro na raça Nelore (Bos indicus), dificulta a detecção do estro nos programas convencionais de inseminação artificial. A fim de contornar este problema, foram testados tratamentos hormonais para ...

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 ...
Endometritis treatment with a PGF2a analog does not improve reproductive performance in a large dairy herd in Argentina
(Elsevier, 2005-03-15)
In Argentina, most dairy cows with endometritis are treated with prostaglandin (PGF2α or its analogs) and insemination is withheld until there are no signs of endometritis. The objective of the present study was to evaluate ...
