Respostas endócrinas e ovarianas associadas com o folículo dominante da primeira onda folicular em ovelhas sincronizadas com CIDR ou PGF2alfa
(Revista Brasileira de Zootecnia, 2002-04-01) [Artigo]
Os efeitos de prostaglandina (PGF2a) vs CIDR e eCG (gonadotrofina coriônica eqüina) na dinâmica folicular da primeira onda e sua relação com as concentrações plasmáticas de P4 e E2 foram investigadas em ovelhas cíclicas. ...
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 ...
Development of a cryopreservation protocol for equine mesenchymal stem cells obtained from umbilical cord
(Journal of Equine Veterinary Science, 2014) [Artigo]
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) ...
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 ...

O objetivo do trabalho foi avaliar a taxa de maturação nuclear in vitro de oócitos provenientes de gatas doméstica púbere e pré-púbere. Foram utilizadas 15 fêmeas felinas, 10 púberes e 5 pré-púberes; sendo os oócitos obtidos ...
Cinta de náilon como cerclagem óssea - estudo experimental em coelhos e ratos
(Semina: Ciências Agrárias, 2013-01-01) [Artigo]
The aim of this study was to evaluate the biocampatibility of the commercial nylon band used as bone cerclage, comparing with traditional metal cerclage wires. Twenty one rabbits and fifteen rats, healthy and without ...
Immunophenotypic, immunocytochemistry, ultrastructural, and cytogenetic characterization of mesenchymal stem cells from equine bone marrow
(Microscopy Research and Technique, 2013-06-01) [Artigo]
The aim of this study was to isolate, culture, and characterize mesenchymal stem cells (MSCs) from horse bone marrow (BM) using the techniques of flow cytometry, immunocytochemistry, cytogenetics, and electron microscopy. ...
Canine corpus luteum regression: Apoptosis and caspase-3 activity
(Theriogenology, 2006-10-01) [Artigo]
The present study evaluated the occurrence of apoptosis and caspase-3 activity in the canine corpus luteum during the period of luteal regression in eight pregnant and nine nonpregnant diestrus bitches. Intact luteal cells ...
