Folate deficiency during pregnancy has been related to low birth weight, preterm (PT) birth and other health risks in the offspring; however, it is unknown whether prematurity is related to low folate transport through the placenta due to altered expression of specific folate transporters. We determined placental expression (mRNA and protein concentrations by RT-qPCR and WB respectively) of specific folate transporters: RFC, PCFT/HCP1 and FOLR1 in chorionic (fetal) and basal (maternal) plates of placentas of PT pregnancies (PT, 32-36 weeks, n = 51)...

PURPOSE: Hormone-related factors have been associated with ovarian cancer, the strongest being parity and oral contraceptive use. Given reductions in birth rates and increases in oral contraceptive use over time, associations in more recent birth cohorts may differ. Furthermore, consideration of ovarian cancer heterogeneity (i.e., Type I/II invasive cancers) may contribute to a better understanding of etiology. We examined hormone-related factors in relation to ovarian cancer risk overall, for Type I and Type II cancers, as well as borderline tumors...

REVIEW
Aparna Sridhar, Jennifer Salcedo
Postpartum contraception is important to prevent unintended pregnancies. Assisting women in achieving recommended inter-pregnancy intervals is a significant maternal-child health concern. Short inter-pregnancy intervals are associated with negative perinatal, neonatal, infant, and maternal health outcomes. More than 30% of women experience inter-pregnancy intervals of less than 18 months in the United States. Provision of any contraceptive method after giving birth is associated with improved inter-pregnancy intervals...

With the development of treatment, the survival rate of premature infants has significantly increased, especially extremely premature infants and very low birth weight infants. This has led to an increase in incidence of bronchopulmonary dysplasia (BPD) year by year. BPD has been one of the most common respiratory system diseases in premature infants, especially the small premature infants. Arrested alveolar development is an important cause of BPD. Therefore, the mechanism of arrested alveolar development and the intervention measures for promoting alveolar development are the focuses of research on BPD...

Early enriched environment (EE) prevents several deficits associated with postnatal MK-801 [N-Methyl-D-Aspartate (NMDA) receptor antagonist] treatment such as cognitive and locomotor deficits. We sought physiological correlates to such changes by looking at inhibitory synaptic inputs onto pyramidal cells in a prefrontal cortex slice preparation. Pharmacologically isolated γ-amino-butyric acid A (GABAA) receptor-mediated currents were measured using whole-cell patch clamp recordings. Wistar rats were raised in standard or EE from birth up to the time of experiments and were injected with saline or MK-801 (1mg/kg) on postnatal days (P) 6-10...

BACKGROUND: Vitamin D has neuroprotective and immunomodulatory properties, and deficiency is associated with worse stroke outcomes. Little is known about effects of hypoxia-ischemia or hypothermia treatment on vitamin D status in neonates with hypoxic-ischemic encephalopathy (HIE). We hypothesized vitamin D metabolism would be dysregulated in neonatal HIE altering specific cytokines involved in Th17 activation, which might be mitigated by hypothermia. METHODS: We analyzed short term relationships between 25(OH) and 1,25(OH)2 vitamin D, vitamin D binding protein, and cytokines related to Th17 function in serum samples from a multicenter randomized controlled trial of hypothermia 33(0)C for 48h after HIE birth versus normothermia in 50 infants with moderate to severe HIE...

PURPOSE: Due to the high number of multiple embryo transfers into the uterus performed in assisted reproductive technology treatment (ART), the incidences of twin pregnancy and of vanishing twin syndrome (VTS) are correspondingly high. A number of studies have described the obstetric outcomes of the remaining fetus produced after the other twin had vanished compared with a singleton at the start following ART, but the results are mixed and contradictory. We performed a systematic review of the existing studies to explore the actual obstetric outcome of VTS to allow physicians to adequately advise their patients...

Mouse models showing an improved fertility phenotype are barely described in the literature. In the present study, we further characterized two outbred mouse models that have been selected for the phenotype 'high fertility' for more than 177 generations (fertility lines (FL) 1 and 2). In order to delineate the impact of males and females on fertility parameters, we performed a two-factorial breeding experiment by mating males and females of the three different genotypes (FL1, FL2, unselected control (Ctrl)) in all 9 possible combinations...

The non-syndromic cleft lip and/or palate (NSCL/P) is a common birth defect caused by a combination of genetic and environmental factors. The possible role of genome instability on NSCL/P patient needs more investigation, since DNA metabolism is an essential cellular function to keep cells with normal genotypes and gene expression patterns according to tissue specificities, which is critical during embryo development because it requires sensitive regulation of cell proliferation, apoptosis and differentiation...

BACKGROUND: The similarities between swine and humans in physiological and genomic patterns, and the great correlation in size and anatomy, make pigs extremely useful in preclinical studies. New-born piglets can represent a model for congenital and genetic diseases in new-born children. It is known that piglets may have significant differences in clinicopathological results compared to adult pigs. Therefore, adult laboratory reference intervals cannot be applied to piglets. The aim of this study was to compare haematological and chemical variables in piglets of two ages and determinate age-related reference intervals for commercial hybrid young pigs...
