Ovulation rate and its relationship with follicle diameter and gene expression of the LH receptor (LHR) in Nelore cows
(Theriogenology, 2012-01-01) [Artigo]
The objective was to determine the relationship among the diameter of ovarian follicles, ovulation rate, and gene expression of the LH receptor (LHR) in Nelore cattle. In Experiment 1, ovulation was synchronized in 53 ...
Use of LH or eCG in the last day of superestimulatory treatment
(Acta Scientiae Veterinariae, 2010-12-01) [Artigo]
In the last decades several hormonal treatments to induce multiple ovulation and embryo transfer (MOET) have been developed. Tight control of the time of ovulation allowed the use of fixed-time artificial insemination ...
Differential Expression of IGF Family Members in Heat-Stressed Embryos Produced In Vitro from OPU-Derived Oocytes of Nelore (Bos indicus) and Holstein (Bos taurus) Cows
(Reproduction in Domestic Animals, 2013-12-01) [Artigo]
Contents The IGF system is related to embryo quality. We aim to determine the effect of the heat stress on the mRNA expression of IGF1 and IGF2, IGFR1 and IGFR2, IGFBP2 and IGFBP4, and PAPPA in in vitro production (IVP) ...
Reproductive tract development and puberty in two lines of Nellore heifers selected for postweaning weight
(Theriogenology, 2013-07-01) [Artigo]
The objective was to evaluate reproductive tract development (ovary and uterus) and onset of puberty in two lines of Nellore heifers (Bos indicus) selected for postweaning weight. A total of 123 heifers, including 46 from ...
Expression of fibroblast growth factor 10 and cognate receptors in the developing bovine ovary
(Theriogenology, 2014-06-01) [Artigo]
In the mammalian ovary, FGF10 is expressed in oocytes and theca cells and is a candidate for paracrine signaling to the developing granulosa cells. To gain insight into the participation of FGF10 in the regulation of fetal ...
Expression of fibroblast growth factor 10 and its receptor, fibroblast growth factor receptor 2B, in the bovine corpus luteum
(Molecular Reproduction and Development, 2008-05-01) [Artigo]
There is evidence that several fibroblast growth factors (FGFs) are involved in growth and development of the corpus luteum (CL), but many FGFs have not been investigated in this tissue, including FGF10. The objective of ...
FOLLICULAR DIAMETER and OVULATION RATE IN NELLORE COWS TREATED WITH LH

Fibroblast growth factor 10 (FGF-10) gene expression in bovine antral follicles.
(Biology of Reproduction, 2004-01-01) [Resumo]
PGFM 13,14-diidro 15-keto prostaglandin F-2 alpha release in response to oxytocin challenge during early postpartum in Nelore cows
(Reproduction in Domestic Animals, 2008-07-01) [Resumo]
PROFILE of MEMBERS of IGF SYSTEM GENE EXPRESSION IN BOVINE IMMATURE OOCYTES: COMPARISON BETWEEN NELLORE (BOS INDICUS) and HOLSTEIN (BOS TAURUS)
(Reproduction, Fertility and Development, 2010-01-01) [Resumo]
