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) ...
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. ...
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 ...
Uso de tecnologias de informação e comunicação (tic) no ensino superior: a superação de um mito.
(Congresso Estadual Paulista sobre Formação de Educadores, 2011) [Trabalho apresentado em evento]
Phosphatidylcholine and Sphingomyelin Profiles Vary in Bos taurus indicus and Bos taurus taurus In Vitro- and In Vivo-Produced Blastocysts
(Biology of Reproduction, 2012-12-01) [Artigo]
Lipid droplets, subspecies (Bos taurus indicus vs. Bos taurus taurus), and in vitro culture are known to influence cryopreservation of bovine embryos. Limited information is available regarding differences in membrane ...
Ovarian response to porcine FSH in association with ablation-induced or spontaneous follicular wave development during the estrous cycle in crossbred and Brazilian Warmblood mares
(Animal Reproduction Science, 2013-02-01) [Artigo]
The primary objective of this study was to examine the follicular and ovulatory responses following treatment with pFSH in association with ablation-induced or spontaneous follicular wave emergence or follicle deviation ...
Cryotolerance and global gene-expression patterns of Bos taurus indicus and Bos taurus taurus in vitro- and in vivo-produced blastocysts
(Reproduction Fertility And Development, 2014-01-01) [Artigo]
In a 2x2 factorial experimental design, embryo development, cryotolerance and global gene expression of Nellore (Bos taurus indicus) and Simmental (Bos taurus taurus) blastocysts produced in vitro (IVP) and in vivo (multiple ...
