1. Relationship between fetal biometric assessment by ultrasonography and neonatal lamb vitality, birth weight and growth
Abstract Ultrasonographic examination of pregnant ewes can enable the identification of perinatal abnormalities and establish prenatal assistance responsible for minimizing morbidity and perinatal mortality. Therefore, we aimed to evaluate the feasibility of a fetal biometric analysis by ultrasonography to predict neonatal vitality and lamb growth during the

2. Avaliação de componentes estruturais do placentomo da vaca Nelore
This study was conducted to better understand the morphologic characteristics of the placentome of the Nelore cow throughout gestation. The experiment was conducted in labs of the Veterinary School of the Federal University of Minas Gerais and in the Cytology, Histology and Embryology lab of the Federal University of Uberlandia, using uteri of 52 Nelore cows

3. Histological and BMP and Wnt gene expression evaluation in the bovine endometrium during embryo implantation / Avaliação histologica e da expressão genica de BMP e Wnt no endometrio durante a implantação embrionaria em bovinos
A implantação embrionária implica em alterações profundas do ambiente uterino, cujos eventos devem obedecer uma sincronia temporal e espacial com o estágio do desenvolvimento embrionário. Qualquer desequilíbrio nesta sincronia resulta em interrupção da gestação e o desconhecimento dos mecanismos que atuam nas interações materno-fetais inviabili

4. Expression of mRNA of the VEGF, Flt-1 and KDR in placentome, interplacentomal areas and gestational corpus luteum in different phases of pregnancy in cloned and non-cloned bovines / Expressão do mRNA do VEGF, FIt-1 e KDR no placentoma, região interplacentomal e corpo lúteo em diferentes fases gestacionais em bovinos clonados e não clonados
The VEGF is a specific endothelial mitogenic factor that promotes feto-maternal cell differentiation in placenta through binding to its receptors (Flt-1 and KDR). Their expression is controlled by autocrine and paracrine mechanisms that are associated to placenta development. The bovine placenta was used in this study as a model due to easiness of evaluation

5. Studies on the distribution of binucleate cells in the placenta of the sheep with a monoclonal antibody SBU-3.
The distribution of cells recognised by the monoclonal antibody SBU-3 raised against trophoblast microvilli during development of the sheep placenta was investigated using the indirect immunoperoxidase technique. At 21 days of gestation, the placental antigen recognised by the monoclonal antibody SBU-3 was observed in the binucleate cells in the trophoblast
