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 ...
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 ...
Effect of different glycerol concentrations on the viability of domestic cat frozen-thawed semen
(Reproduction in Domestic Animals, 2008-07-01) [Resumo]
Cryoprotective effect of different glycerol concentrations on domestic cat spermatozoa
(Theriogenology, 2013-10-15) [Artigo]
Cryopreservation of spermatozoa is a pivotal tool in assisted reproduction, and studies aiming to establish optimal freezing/thawing protocols are essential to enhance sperm survival. The objectives of the present study ...
Impact of 24-h Cooling Prior to Freezing on the Survival of Domestic Cat (Felis catus) Epididymal Sperm
(Reproduction in Domestic Animals, 2009-07-01) [Artigo]
The aim of this study was to investigate the impact of a 24-h cooling period prior to freezing on domestic cat epididymal sperm viability. Fifteen tomcats were submitted to routine orchiectomy and sperm samples were retrieved ...
