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. Development and validation a task-specific checklist for a microsurgical varicocelectomy simulation model
ABSTRACT Purpose: To develop and validate a new test of specific technical skills required for microsurgical varicocelectomy. Materials and Methods: An electronic questionnaire was sent to 558 members of the Brazilian Society of Urology for the validation of the task-specific checklist (TSC) for assessment of microsurgical varicocelectomy. Participants who

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. Kaempferol inhibited VEGF and PGF expression and in vitro angiogenesis of HRECs under diabetic-like environment
Diabetic retinopathy (DR) is one of the common and specific microvascular complications of diabetes. This study aimed to investigate the anti-angiogenic effect of kaempferol and explore its underlying molecular mechanisms. The mRNA expression level of vascular endothelial growth factor (VEGF) and placenta growth factor (PGF) and the concentrations of secrete

5. Implications arising from the use of Cymbopogen proximus ; proximal on placenta of pregnant Albino rats
ABSTRACT Halfa-bar (Cymbopogon proximus), is an aromatic grass widely growing in Upper Egypt. This herb is recommended for medical purposes as an effective diuretic, renal or abdominal antispasmodic agent. Objectives of this study: Evaluate the potential effects of Halfa-bar on the pregnant albino rats during the gestation period. Material and methods: The v

6. Placental hydroxymethylation vsmethylation at the imprinting control region 2 on chromosome 11p15.5
In addition to methylated cytosines (5-mCs), hydroxymethylcytosines (5-hmCs) are present in CpG dinucleotide-enriched regions and some transcription regulator binding sites. Unlike methylation, hydroxymethylation does not result in silencing of gene expression, and the most commonly used methods to study methylation, such as techniques based on restriction e

7. HLA-G polymorphism in mother-child transmission of HIV-1 / Polimorfismo do HLA-G na transmissão materno-infantil do HIV-1
The main way of HIV-1 infection in children is mother-child transmission (MTCT). TMI rates estimates for HIV-1 are 3% in pregnant women in antiretroviral therapy and 25 to 30% for untreated ones. Despite the viral exposure during pregnancy, most newborns are not vertically infected, suggesting the existence of protective barriers to TMI of HIV-1. Several fac

8. Níveis da quimiocina RANTES na placenta, plasma materno e plasma do cordão umbilical em gestantes normais e com síndrome de pré-eclâmpsia
Objective: To estimate RANTES levels at maternal plasma, umbilical cord blood plasma and placenta in preeclampsia syndrome and normal pregnancy. Methods: A cross-sectional study was conducted to estimate RANTES levels in maternal plasma, placenta and cord blood plasma in preeclampsia syndrome (n=33) compared to a control group of women with normal pregnancy

9. Transferência de anticorpos reativos com intiminas α, β, γ de Escherichia coli pela placenta e aleitamento materno: determinação quantitativa em soros de recém-nascidos e soros e colostros de suas mães / Transference of antibodies reactive with intimins α, β and γ of Escherichia coli by placenta and breastfeeding: quantitative determination in the sera of newborns and the colostrum and sera of their mothers
Intimina é uma adesina de natureza protéica das bactérias diarreiogênicas Escherichia coli enteropatogenica (EPEC) e enterohemorrágica (EHEC), capazes de induzir a lesão \ attaching e effacing\ em enterócitos. Os principais subtipos de intiminas de EPEC e EHEC prevalentes no Brasil são α, β e γ. Nosso objetivo foi investigar a transfer

10. 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,

11. Mortalidade infantil em Londrina (PR) em anos recentes : características e percepções de gestores e profissionais de saúde
Infant mortality reaches a population group of liveborn infants younger than one year of age, who are vulnerable to life conditions, both to intra and extra-uterine environments. Knowing the causes of deaths and factors associated to them may provide valuable information to health care providers for improving health care. Therefore, this study had two approa

12. 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
