1. Anti-Zika Virus Effects, Placenta Protection and Chemical Composition of Passiflora edulis Seeds Ethanolic Extract
Various beneficial biological activities have been reported for passion fruit (Passiflora edulis), grown in tropical and subtropical regions. However, no study has yet demonstrated its action against the Zika virus (ZIKV) infection. The present study aimed to investigate the anti-ZIKV of the ethanolic passion fruit seed extract (PFSE), from which, liquid chr

2. Susceptibilidade diferencial de células trofoblásticas humanas (BeWo) e cervicais uterinas (HeLa) à infecção por Neospora caninum
Neospora caninum is an obligate intracellular parasite, closely related to Toxoplasma gondii, and considered a major cause of abortion and congenital neosporosis in cattle worldwide. As trophoblast cells act in mechanisms of innate immune defense at fetal-maternal interface, and no data are available about the interaction of this parasite with human trophobl

3. Apoptose e proliferação celular em células trofoblásticas (linhagem BeWo) são diferentemente moduladas pelas cepas de Toxoplasma gondii
Transplacental transmission causes one of the most severe forms of infection with protozoan parasite Toxoplasma gondii. The ability of the parasite to survive intracellularly largely depends on the blocking of different proapoptotic signaling cascade of its host cell. However, alterations in the incidence of apoptosis, during pregnancy, are associated with a

4. Uso de matriz extracelular (Matrigel®) para estabelecimento de cultivo de células-tronco embrionárias de suínos e caracterização da expressão de moléculas associadas à pluripotência / Use of extracellular matrix (Matrigel®) for establishment of porcine embryonic stem cells and expression characterization of plurpotency related molecules
Establishment of embryonic stem cell (ESC) culture in pigs has not been achieved. Verification of pluripotency markers and differentiation in the three embryonic layers are necessary for validation of a pluripotent cell line. The objective of this study was to establish and characterize porcine ESC culture using Matrigel and compare the expression of pluripo

5. Expressão e atividade da NAD(P)H-oxidase de membrana nas células trofoblásticas de camundongos. / Expression and activity of the membrane NADP(H) - oxidase in the mouse trophoblast cells.
As células trofoblásticas provenientes de cones ectoplacentários na fase de pós-implantação expressam as subunidades do complexo NAD(P)H-oxidase de membrana p22-phox, gp91-phox, p47-phox, p40-phox, p67-phox e Rac1 previamente descritas em fagócitos e envolvidas com a atividade fagocitária destas células. Ocorre modulação da expressão das subunida

6. 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

7. Avaliação da espressão de glicoproteinas potencialmente especificas na membrana plasmatica de celulas Natural Killer uterinas de camundogos / Evaluation of expression of potentially specific glycoproteins in plasmatic membrane of mouse uterine Natural Killer
The phenomenon of pregnancy in mammalians with hemochorial type placenta ions where the allogeneic fetus presenting the half of gene from paternal origins growth in tight contact with maternal tissues, without triggering the rejections responses of maternal immune system is still a non-solved question of immunology of reproduction. The cross-talk at maternal

8. A subplacenta da paca (Agouti paca, Linnaeus 1766) / The subplacenta of the paca (Agouti paca, Linnaeus 1766)
The rodents of suborder hystricomorph, in which is classified the Agouti paca, present hemochorial type placentation and develops an unique structure known as subplacenta. In spite of many report of its presence in several species, the possible functions of this structure related to placenta and pregnancy remains speculative, mainly due to the diversity of f

9. À procura do Ped bovino / Searching for the Ped gene
The aim of the present work was to identify bovine MHC class I genes similar to the murine Ped gene expressing during embryonic development and pregnancy. Bovine in vitro produced embryos and placentas obtained from natural mating or cloning-derived fetuses had their RNA extracted. cDNA was synthesized to isolate fragments showing similarity with the gene de

10. Aspectos morfometricos e funcionais da placenta de ratas Wistar 256
In the present study we investigated the influence of Walker 256 tumor growth on the modification of placental morphometry and on fetal development in young and adult pregnant rats. After mating, female rats were divided into six groups: Young control pregnant (YP), young pregnant with tumor (YW), young pregnant injected with ascitic fluid (YAs), adult contr

11. Uric acid attenuates trophoblast invasion and integration into endothelial cell monolayers
Hyperuricemia develops as early as 10 wk of gestation in women who later develop preeclampsia. At this time the invasive trophoblast cells are actively remodeling the uterine spiral arterioles, integrating into and finally replacing the vascular endothelial lining. In the nonpregnant population uric acid has several pathogenic effects on vascular endothelium

12. Diethylstilbestrol regulates trophoblast stem cell differentiation as a ligand of orphan nuclear receptor ERRβ
The orphan nuclear receptor ERRβ is expressed in undifferentiated trophoblast stem cell lines and extraembryonic ectoderm, and genetic ablation of ERRβ results in abnormal trophoblast proliferation and precocious differentiation toward the giant cell lineage. Here, we show that the synthetic estrogen diethylstilbestrol (DES) promotes coactivator release fr
