13. Estudo do desenvolvimento do aparelho digestório de embriões bovinos (Bos indicus e Bos taurus) durante o período gestacional compreendido entre 10 e 60 dias / Study of development of digestive tract of bovine embryos (Bos indicus and Bos taurus) during gestational period between 10 and 60 days
The embryonary period extends itself from 15th to 45th day of gestation in cows, when a fast growing and differentiation occurs, during which the main organs, tissues and systems are established and the main characteristics are recognized. In bovines, most of the organs and parts of body are formed between 2th and 6th week of gestation. During this period, t

14. Desenvolvimento embrionário em ratas wistar prenhes submetidas ao ultra-som terapêutico de 3 MHz
Therapeutic ultrasound is widely used in different aesthetic treatment by young women, who can be irradiated during early gestation. Researches regarding the effects of therapeutic ultrasound on gestation present controversial results. Methodologies incompatible with clinical aspects are used and different methods and technics were employed. However none of

15. Passagem celular, sexo e transcrição X-específica interferem no desenvolvimento embrionário e fetal de bovinos produzidos por transferência nuclear / Celular passage, sex and X-specific transcription interfere in bovine nuclear transfer embryo and fetal development
Cells cultured for long-term periods accumulate genetic and epigenetic modifications that result in improper nuclear reprogramming of somatic cell nuclear transfer (SCNT) embryos. Furthermore, the sex may be a limiting factor in blastocysts production and in post-implantation developmental competence. Therefore, the objective of this study was to determine t

16. Polymorphisms in MUC1 and osteopontin genes in Nelore heifers / Polimorfismos dos genes MUC1 e Osteopontina em novilhas da raça Nelore (Bos taurus indicus)
MUC1 (MUC1) and osteopontin (SPP1) are glycoproteins expressed in the uterine luminal surface with predict functions in protection and cell adhesion. MUC1 has anti-adhesive role and osteopontin has adhesive role. The expression of both molecules is regulated by the steroid hormone, progesterone. During the receptive period for embryo implantation in the uter

17. Avaliação do potencial embriotóxico do Tacrolimus (Fk506) administrado a ratas Wistar
O tacrolimus é um antibiótico macrolídeo com ação imunossupressora, atuando como inibidor de calcineurina, que vem sendo utilizado como droga base na maioria dos transplantes para evitar rejeição. Com o êxito dos transplantes, decorrente principalmente do uso de imunossupressores, houve uma melhora na qualidade de vida das pacientes transplantadas. E

18. Blastocyst-endometrium interaction: intertwining a cytokine network
The successful implantation of the blastocyst depends on adequate interactions between the embryo and the uterus. The development of the embryo begins with the fertilized ovum, a single totipotent cell which undergoes mitosis and gives rise to a multicellular structure named blastocyst. At the same time, increasing concentrations of ovarian steroid hormones

19. Criopreservação oocitária: desempenho reprodutivo na fertilização assistida.
The advance of in vitro fertilization (IVF) caused the emergence of a few dilemmas that forcibly led to deep reflections, standing out among these the questioning about the destination of excess embryos originated from this technology. In view of the controversy observed in several cultures as to ethic, moral, religious, political and scientific issues relat

20. Distribution of versican and hyaluronan in the mouse uterus during decidualization
Preparation for embryo implantation requires extensive adaptation of the uterine microenvironment. This process consists of cell proliferation and cell differentiation resulting in the transformation of endometrial fibroblasts into a new type of cell called decidual cell. In the present study, we followed the space-time distribution of versican and hyalurona

21. Ação da indometacina sobre o conteudo lipidico das celulas deciduais de camundongos : estudo histoquimico e morfometrico
ln the aim to analyze the commitment of lipid droplets and their phopholipds contents in the decidual cells as prostaglandin precursors, it was loculated intraperitoneal " 40 AL of 25mg indomethacin, a powerful inhibitor of prostaglandin-synthase, solubilized in sesame oil, in the female mice on the fifth days of pregnancy. Controls animais received the same

22. Diagnostico imunologico e efeito de imunizações com linfocitos em pacientes com aborto espontaneo recorrente
t: Pregnancy can be considered as a very successful all graft, but the underlying mechanism is not yet completely understood. HLA all tigens compatibility is very important in c1inic transplant due to their all ore cognition by immune system. Nevertheless, genetic differences between maternal and paternal HLA antigens seem to be an important factor for impla

23. Estudo imunocitoquimico das catepsinas D e B em celulas trofoblasticas gigantes de camundongos
The trophoblastic giant cells (TGC) differentiate from trophectoderm sheets or from the ectoplacental cone of mouse embryos and are committed to blastocyst implantation and placentation. It has attributed a high invasive capability and phagocytosis to the TGC which degenerate and remove the maternal tissues. However, the exact mechanism controlling their inv

24. Spatial and temporal alterations of phospholipids determined by mass spectrometry during mouse embryo implantation[S]
Molecular events involved in successful embryo implantation are not well understood. In this study, we used MALDI imaging mass spectrometry (IMS) technologies to characterize the spatial and temporal distribution of phospholipid species associated with mouse embryo implantation. Molecular images showing phospholipid distribution within implantation sites cha
