Níveis de PGF2α e esteroides gonadais durante a hipofisação de Piaractus mesopotamicus com ou sem uso de PGF2α exógena
(Universidade Estadual Paulista (Unesp), 2018-02-28)
O principal objetivo deste trabalho foi determinar as concentrações plasmáticas de 17α,20β-dihidroxi-4-pregnen-3-one (DHP), Estradiol 17β (E2), Testosterona (T) e Prostaglandina F2α (PGF2α) e a distribuição percentual dos ...
Endometrial prostaglandin f2α in vitro production and its modulation regarding dominant follicle position in cattleProdução in vitro de pgf f2α endometrial e sua modulação referente ao folículo dominante em bovinos
(2019-07-26)
Prostaglandin F2α (PGF2α) determines luteolysis in cattle, and the ability to manipulate its endogenous synthesis is indispensible for large-scale animal breeding. Estradiol (E2) and progesterone (P4) modulate several ...
Inducción del celo y porcentaje de preñez en vaquillas de razas lecheras implantadas con dispositivos intravaginales y diferentes tiempos de aplicación de la PGF2α

Calcium potentiates the effect of estradiol on PGF2α production in the bovine endometrium
(BioMed Central, 2014-05-05)
Abstract
Background
Estradiol (E2) is required for luteolysis in cows and its injection stimulates prostaglandin F2α (PGF2α) release. The main goal of our study was to ...

Resposta luteal à PGF2α (Dinoprost Trometamina) durante as fases de luteogênese e manutenção do corpo lúteo em éguas
(Universidade Estadual Paulista (Unesp), 2014-07-14)
Recent studies have demonstrated different response of the CL to different doses of prostaglandin F2α on differente moments. The present experiment aims to evaluate the effect of treatments with PGF2α low doses over ...
Resumption and progression of meiosis and circulating levels of steroids and prostaglandin F2α of Piaractus mesopotamicus induced by hypophysation with prostaglandin F2α
(2021-03-01)
We have previously shown an increase on the ovulation rate of pacu, Piaractus mesopotamicus, using hypophysation with prostaglandin F2α (PGF2α) (HPG protocol) rather than hypophysation (H); only, however, a persistent lack ...
Respuesta a la inducción y sincronización del celo con CIDR®, GnRH y PGF2α en vacas de doble propósito en anestro

Mechanisms for rescue of corpus luteum during pregnancy: gene expression in bovine corpus luteum following intrauterine pulses of prostaglandins E1 and F2α
(Biology of ReproductionEstados Unidos, 2017-12-27)
In ruminants, uterine pulses of prostaglandin (PG) F2α characterize luteolysis, while increased PGE2/PGE1 distinguish early pregnancy. This study evaluated intrauterine (IU) infusions of PGF2α and PGE1 pulses on corpus ...
