Arsenic is a carcinogen with transplacental activity that can affect human skin stem cell population dynamics in vitro by blocking exit into differentiation pathways. Keratinocyte stem cells (KSC) are probably a key target in skin carcinogenesis. Thus, we tested the effects of fetal arsenic exposure in Tg.AC mice, a strain sensitive to skin carcinogenesis via activation of the v-Ha-ras transgen...

INTRODUCTION Management of complicated monochorionic twins and certain intrauterine structural anomalies is a pressing challenge in communities that still lack advanced fetal therapy. We describe our efforts to rapidly initiate selective feticide using radiofrequency ablation (RFA) and selective fetoscopic laser photocoagulation (SFLP) for twin-to-twin transfusion syndrome (TTTS), and present t...

OBJECTIVE To present the appearance of the fetal akinesia deformation sequence by three-dimensional ultrasonography after four-dimensional ultrasonographic scanning. METHODS Three-dimensional surface-rendering images were used to show the fixed postural abnormalities of the fetal extremities and body. Four-dimensional ultrasonography was used to show that the postural abnormalities were fixed...

BACKGROUND Fragments of DNA from cells dying throughout the body are detectable in urine (transrenal DNA, or Tr-DNA). Our goal was the optimization of Tr-DNA isolation and detection techniques, using as a model the analysis of fetal DNA in maternal urine. METHODS We isolated urinary DNA using a traditional silica-based method and using a new technique based on adsorption of cell-free nucleic ...

The developing fetal brain is vulnerable to a variety of environmental agents including maternal ethanol consumption. Preclinical studies on the development and amelioration of fetal teratology would be significantly facilitated by the application of high resolution imaging technologies like optical coherence tomography (OCT) and high-frequency ultrasound (US). This study investigates the abili...

introduction: it is well know that fetal distress is one of the important causes of fetus perinatal morbidity and mortality. in this study, we sought to evaluate the association between umbilical coiling index and fetal distress.material and method:this was a case- control study conducted on 90 term pregnant women. study group had fetal distress (abnormal fetal heart rate, meconium staining, ap...

There is growing international evidence of the benefits early perinatal palliative care for babies and their families. Despite this, inconsistency remains in ways provided by services including fetal medicine, maternity neonatal services, children's hospices. The aim this study was to answer question “ What are barriers family-centered advance planning from perspective professionals involved ne...

The murine primordial follicle pool develops largely within 3 days after birth through germline nest breakdown and enclosure of oocytes within pregranulosa cells. The mechanisms that trigger primordial follicle formation likely are influenced by a transition from the maternal to fetal hormonal milieu at the time of birth. High levels of maternal estrogen maintain intact germline nest in fetal o...
