introduction: it is clear that the proliferation, migration and differentiation processes of embryonic fetal neural tissue are dependent on special trophic factors. these factors are absent or lessl seen in adult tissue. in this research the effects of fetal brain extract (fbe) on the regenerational processes of lesioned prepheral nerve were investigated. materials and methods: the facial nerve...

Background: In most cancer cases, the treatment choice for a pregnant patient is radiotherapy. In these patients, the abdomen is usually not exposed therefore fetus exposure is due to peripheral dose (PD). The purpose of this study was to estimate the fetal dose (the maximum PD in each pregnancy stage) for modalities available and to fabricate and evaluate a generally applicable fetal ...

Prospective isolation and characterization of progenitor cells is a paradigmatic strategy for studies of organ development. However, extraction of viable cells, fractionation of lineages, and in vitro analysis of progenitors from the fetal pancreas in experimental organisms like mice has proved challenging and has not yet been reported for human fetal pancreas. Here, we report isolation of panc...

The influence of maternal hypothyroxinemia on the expression of the glucose transporters, GLUT1 and GLUT3, in rat fetal brain and placenta was investigated. Fetal growth was retarded in hypothyroxinemic pregnancies, but only before the onset of fetal thyroid hormone synthesis. Placental weights were normal, but placental total protein concentration was reduced at 19 days gestation (dg). Immunob...

Front cover: Cover image: Distribution of HOPX and BLBP in cerebellum brain stem from a 21 wpc human fetal brain. is most prevalent corpus pontobulbare (CPB). seem to occupy different regions this cellular aggregate dominated by strong immunoreactivity. also scattered the present dentate nucleus as well blood vessel walls. In cerebellar cortex mostly confi ned Purkinje cell layer. Also note rea...

Background: Toxoplasma gondii is a significant cause of abortion in sheep and goats in the world. Toxoplasmosis is caused reproduction disorders such as fetal resorption, early embryonic death, mummification, abortion, stillbirth, neonatal and fetal death in sheep . Objectives: The aim of this study was to detect T. gondii infection in ovine aborted fetuses in Khorasan Razavi province. Methods:...

the first step in the prenatal diagnosis of x-linked genetic disorders is determining fetus gender. current invasive methods to obtain the dna source of the fetus instead of its miscarriage risk, has harmful stress for high risk pregnancies. cell free fetal dna (cffdna) circulating in the maternal blood, has now become a useful source of noninvasive prenatal diagnosis. considering limitation of...

BACKGROUND Assessment of the fetal brain volume and blood flow is important in the evaluation of fetal growth. We used three-dimensional (3D) ultrasound and power Doppler to assess the fetal brain volume and the blood flow index during normal gestation. The relationships of these parameters were further analyzed. METHODS We assessed the total volume and the blood flow index of the fetal brain...
