During human implantation trophoblasts mediate attachment of the embryo to the uterine epithelium and invade and reorganize vessels of the maternal endometrium to initiate blood flow to the intervillous space. Expression of the nonclassical MHC class I molecule HLA-G by invading trophoblasts may play a central role in their protection from recognition by the maternal immune system; however, the...

BACKGROUND PGD has been described in previous cross-sectional and retrospective studies as a stressful experience. No prospective studies of the psychological impact of PGD are currently available. METHODS Using a prospective study design, validated measures exploring anxiety and depression were used to assess women using PGD prior to treatment, following embryo transfer, following the pregna...

Extraembryonic ectoderm differentiation and chorioallantoic attachment are fibroblast growth factor (FGF)- and transforming growth factor beta-regulated processes that are the first steps in the development of the placenta labyrinth and the establishment of the fetal-maternal circulation in the developing embryo. Only a small number of genes have been demonstrated to be important in trophoblast...

Objective: the aim of this study was to investigate relationship between periodontal health condition and weight fetuses in Iraqi pregnant women order magnify importance maintenance during pregnancy. Material Methods: fetus determined using ultrasound scanning for 222 women, accordingly they were divided into two groups: group A: normal B: below fetal weight. Their examined by means Plaque inde...

OBJECTIVE To explore attachment narratives in children diagnosed with reactive attachment disorder (RAD). METHOD We compared attachment narratives, as measured by the Manchester Child Attachment Story Task, in a group of 33 children with a diagnosis of RAD and 37 comparison children. RESULTS The relative risk (RR) for children with RAD having an insecure attachment pattern was 2.4 (1.4-4.2)...

BACKGROUND The aim of the study was to characterize the maternal dimensions of anxiety, depression and prenatal attachment in women undergoing an amniocentesis. METHODOLOGY/PRINCIPAL FINDINGS A prospective observational study was conducted. Women were referred to early amniocentesis for increased nuchal translucency, elevated biochemical markers or advanced maternal age. All participants had ...

Vasa previa is characterized by the presentation of blood vessels umbilical cord, which pass through amniotic sac over inner eye cervix or in its immediate vicinity (up to 5 cm) and are associated with cord flow front anterior part fetus.Risk factors for Previa placental pathology, particular placenta low location; membranous attachment IVF, presence an additional share dichotomous placenta, as...

Abstract Purpose of Review Maternal prenatal substance use presents a multilevel risk to child development and parenting. Although parenting interventions are increasingly integrated into treatment, processes have not received equal attention within these interventions. This article aims synthesize the evidence on specific factors affecting early substance-using mothers, as well focusing those ...

Thymic precursor cells (prothymocytes) comprise a large proportion of the fetal thymic cell population, but are less frequently encountered in the postnatal thymus, where they compose < 1% of the entire population. In the present study we attempted to characterize a number of properties of the prothymocytes obtained from human fetal thymic tissues after depletion of the E-rosette thymocyes on a...
