1. Does Enoxaparin treatment have any effects on the placenta in women with unexplained histories of habitual abortion? A case control study
ABSTRACT BACKGROUND: It is very common to offer low molecular weight heparin (LMWH) medications to women with unexplained habitual abortion, to increase the livebirth rate. Although no benefit from LMWH has been clearly demonstrated, examination of the effects of enoxaparin on placental structure is lacking. OBJECTIVE: To assess placental structural chan

2. Fetal death: obstetric, placental and fetal necroscopic factors
RESUMO Introdução: Óbito fetal se define como morte do produto da concepção independente do tempo da gestação. Objetivos: O objetivo deste estudo foi investigar os fatores de risco maternos (obstétricos e placentários) e os achados de necropsia associados ao óbito fetal a partir de dados obtidos no Serviço de Verificação de Óbito (SVO) de Flo

3. Differential expression of microRNA-411 and 376c is associated with hypertension in pregnancy
Preeclampsia is a major reason of morbidity and mortality in pregnant women and perinatal fetus. Hence, it is of prime importance that diagnostic markers are defined to predict chances of preeclampsia in pregnant women. It has been previously shown that microRNA (miRNA)-376c expression is decreased in the placenta of preeclampsia patients at term. Even thoug

4. Maternal exposure to Cochlospermum regium: a toxicological evaluation
Cochlospermum regium (Schrank) Pilg., Bixaceae, is a Brazilian plant widely used as a folk medicine in the southwestern of the Brazil to treat inflammation and infection diseases. However, the effects of C. regium hydroethanolic extract on pregnant rats have not been assessed. To evaluate the effects of the C. regium on pregnant rats during the organogenic p

5. Leptin and adiponectin in the female life course
Adipose tissue secretes a variety of adipokines, including leptin and adiponectin, which are involved in endocrine processes regulating glucose and fatty metabolism, energy expenditure, inflammatory response, immunity, cardiovascular function, and reproduction. The present article describes the fluctuations in circulating leptin and adiponectin as well as th

6. Estudo do padrão de inativação do cromossomo X em tecido extra-embrionário humano / X-chromosome inactivation pattern in human extra-embryonic tissue
Imprinted inactivation of the paternal X chromosome in marsupials is the primordial mechanism of dosage compensation for X-linked genes between females and males in Therians. In Eutherian mammals, X chromosome inactivation (XCI) evolved into a random process in cells from the embryo proper, where either the maternal or paternal X can be inactivated. However,

7. Passive acquisition of protective antibodies reactive with Bordetella pertussis by the newborn via placental transfer and breastfeeding / Aquisição passiva de anticorpos protetores reativos com Bordetella pertussis pelo recém-nascido via transferência placentária e aleitamento materno
Pertussis is currently considered an important public health problem in developed countries. Although there is no evidence of an increase in the number of pertussis cases in our country, can not rule out the hypothesis of a future re-emergence of disease, as epidemiological data from some regions show an increase in incidence, indicating that probably there

8. Study of the alterations in the development, behavior and cerebral biochemistry of male rats exposed to the environmental atmospheric pollution in the intra-uterine phase / Estudo das alterações no desenvolvimento, no comportamento e na bioquímica cerebral de ratos machos adultos expostos à poluição atmosférica ambiental durante a fase intra-uterina e o período de lactação
Experimental studies done at our laboratory demonstrated that the inhalation of residual oil fly ash by the adult rats decreased motor activity of the animals in the open-field test. Additionaly, we showed that rats which inhalated residual oil fly ash preserved its habituation capacity. In this study, oxidative stress in striatum and cerebellum might be the

9. Expression of small leucine-rich proteoglycans: decorin and biglycan, in human normal term placenta and with invasiveness-changed trophoblast pathologies. / Expressão de pequenos proteoglicanos ricos em leucina: decorim e biglicam, em placentas humanas a termo normais e com alterações da invasividade trofoblástica.
O decorim e o biglicam são membros da família dos pequenos proteoglicanos ricos em leucina e possuem importantes funções no controle da proliferação, migração e invasão do citotrofoblasto extraviloso (TEV). O objetivo deste trabalho foi de caracterizar a expressão diferencial e a imunolocalização de decorim e biglicam em placentas humanas normais

10. Comparative study of the VEGF system temporal distribution in the bovine and canine placenta / Estudo comparativo da distribuição temporal do sistema VEGF na placenta de cães e de bovinos
The VEGF family is known to be responsible for the angiogenesis increasing blood vessels number and permeability in the endometrial/placentary interface. A comparative study of VEGF system temporal distribution in canine and bovine placentas, which present very well described differences in structure and function, will contribute to better define the role of

11. 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

12. Perfil sociodemográfico e epidemiológico de gestantes e recém-nascidos e fatores determinantes do peso ao nascer: um estudo de usuários do SUS em Viçosa-MG / Socio-demographical and epidemiological profile of gestational women and newborn infants and determinant weight factors at birth: a SUS study in Viçosa-MG
This study aimed to study the profile of pregnant women and newborn infants attended by the national health system SUS in Viçosa-MG and microregion, as well as to evaluate the predicting factors of weight at birth and placental characteristics of this population. This was a cross-sectional study using 244 puerperium women, their newborn infants (NB) and res
