BACKGROUND: While there are well-accepted standards for the diagnosis of arrested active-phase labor, the definition of a "failed" induction of labor remains less certain. One approach to diagnosing a failed induction is based on the duration of the latent phase. However, a standard for the minimum duration that the latent phase of a labor induction should continue, absent acute maternal or fetal indications for cesarean delivery, remains lacking. OBJECTIVE: The objective of this study was to determine the frequency of adverse maternal and perinatal outcomes as a function of the duration of the latent phase among nulliparous women undergoing labor induction...

We report a gravida in fulminant acute respiratory distress syndrome, mechanically ventilated at 27 weeks estimated gestational age, who further deteriorated into severe combined hypercarbic, hypoxemic respiratory failure. At 30 weeks estimated gestational age, she was placed on venovenous extracorporeal membrane oxygenation (ECMO) because of refractory respiratory failure. Her physical status improved without fetal deterioration. She was managed expectantly in an effort to allow continued fetal maturation...

Blood brain barrier (BBB) is a complex, tight barrier between endothelial cells of cerebral blood vessels. It acts as a physical barrier and provides access to only those moieties which are necessary for proper brain functioning. However, this selective prudence also acts as a hindrance in therapeutic targeting of brain necessitating pharmaceutical intervention. Intranasal drug delivery is one such approach which we have exploited here for targeted brain delivery of asenapine via glycol chitosan coated nanostructured lipid carrier (GC-ANLC)...

Monochorionic twin pregnancies are at increased risk for adverse outcome compared to dichorionic twin pregnancies and singletons. Monochorionic-specific complications include twin-twin transfusion syndrome (TTTS), twin anemia-polycythemia sequence, single intrauterine fetal demise and its consequences on the co-twin, and selective intrauterine growth restriction. Whereas the natural history of monochorionic-specific complications carries a high risk of fetal death or severe neurologic disability, a framework now exists, based on well-designed clinical trials, for optimal treatment of these entities...

Epstein-Barr virus (EBV), a common pathogen in humans, is suspected as the cause of multiple pregnancy-related pathologies including depression, preeclampsia, and stillbirth. Moreover, transmission of EBV through the placenta has been reported. However, the focus of EBV infection within the placenta has remained unknown to date. In this study, we proved the expression of latent EBV genes in the endometrial glandular epithelial cells of the placenta and investigated the cytological characteristics of these cells...

Schmallenberg virus (SBV) is a recently identified member of the genus Orthobunyavirus of the family Bunyaviridae. It is an arbovirus transmitted by different members of Culicoides spp of biting midges. The virus is more recognized for its effect on reproductive disorders in ruminants characterised by abortion, stillbirth and birth of congenitally defective newborns with hydranencephaly-arthrogryposis syndrome. The current study was undertaken with the objectives of exploring the presence of SBV exposure and identification of factors affecting its distribution among dairy cattle in Ethiopia...

Background: Maternal Zika virus (ZIKV) infection with prolonged viremia leads to fetal infection and congenital Zika syndrome. We reported that ZIKV infects primary cells from human placentas and fetal membranes. Here, we studied viral replication in numerous explants of anchoring villi and basal decidua from first-trimester human placentas and mid-gestation amniotic epithelial cells (AmEpCs). Methods: Explants and AmEpCs were infected with American and African ZIKV strains at low multiplicities, and ZIKV proteins were visualized by immunofluorescence...

Accumulating evidences indicate that alcohol might play a causative in oral cancer. Unfortunately, in vitro cell systems, uncovering the molecular background of the underlying cell transformation process, are rare. Therefore, this study was conducted, to identify molecular changes and characterize their putative cell behavioral consequences in epitheloid (EPI) and fibroblastoid (FIB) oral keratinocyte phenotypes, arising from chronical alcohol treatment. Concerning adherens junctions (AJs), both EPI and FIB showed membrane-bound β-catenin, but exhibited differences for E-cadherin and zyxin...

Outcomes of Zika virus (ZIKV) infection in pregnant women vary from the birth of asymptomatic offspring to abnormal development and severe brain lesions in fetuses and infants. There are concerns that offspring affected in utero and born without apparent symptoms may develop mental illnesses. Therefore, animal models are important to test interventions against in utero infection and health sequelae in symptomatic and likely more widespread asymptomatic offspring. To partially reproduce in utero infection in humans, we directly inoculated selected porcine conceptuses with ZIKV...

The design of efficient therapies for age-related macular degeneration (AMD) is limited by our understanding of the pathogenesis of basal deposits, which form between retinal pigment epithelium (RPE) and Bruch's membrane (BrM) early in disease, and involve activation of the complement system. To investigate the roles of BrM, RPE and complement in AMD, we generated abnormal extracellular matrix (ECM) using CRISPR-edited ARPE-19 cells. We introduced to these cells the p.R345W mutation in EFEMP1, which causes early-onset macular degeneration...

Background: Cardiomyocyte progenitor cells (CMPCs) are a promising cell source for regenerative cell therapy to improve cardiac function after myocardial infarction. However, it is unknown whether undifferentiated CMPCs have arrhythmogenic risks. We investigate whether undifferentiated, regionally applied, human fetal CMPCs form a pro-arrhythmic substrate in co-culture with neonatal rat ventricular myocytes (NRVMs). Method: Unipolar extracellular electrograms, derived from micro-electrode arrays (8 × 8 electrodes) containing monolayers of NRVMs (control), or co-cultures of NRVMs and locally seeded CMPCs were used to determine conduction velocity and the incidence of tachy-arrhythmias...

Introduction Fetal exposition to valproate can lead to a cluster of facial dysmorphism, congenital anomalies and neurodevelopmental retardation. Case Report In this report we describe 2 cases of fetal valproate syndrome. In the first case, the gravida had a valproate medication before and during pregnancy with additional folic acid. She delivered a male premature infant at 25+2 weeks of gestation due to preterm labor and rupture of the membranes. Physical examination showed even in the premature infant typical signs of fetal valproate syndrome with trigonocephaly, epicanthal folds, broad root of the nose, low-set ears, thin upper lip and anteverted nares...

Rubella virus (RuV) causes a systemic infection and transplacental fetal infection causes congenital rubella syndrome. In this study, we showed that treatment of cells with sphingomyelinase inhibited RuV infection. Assays using inhibitors of serine palmitoyl transferase and ceramide transport protein demonstrated the contribution of sphingomyelin (SM) to RuV infection. Compelling evidence for direct binding of RuV to lipid membranes at neutral pH was obtained using liposome co-flotation assays. The absence of either SM or cholesterol (Chol) abrogated the RuV--liposome interaction...

BACKGROUND: Studying human genome using chromosomal microarrays has significantly improved the accuracy and yield of diagnosing genomic disorders. Chromosome 7q36 deletions and duplications are rare genomic disorders that have been reported in a limited number of children with developmental delay, growth retardation, and congenital malformation. Altered dosage of SHH and HLXB9, both located in 7q36.3, is believed to play roles in the phenotypes associated with these rearrangements. In this report we describe a child with 7q36...
