of the known mycotoxins, the most important in relation to direct hazard to human health are the aflatoxins produced by a large number of aspergillus spp. to determine the level of exposure of aflatoxin from mother to child and its mode of transfer. 70 pregnant women in the labor ward of the federal medical centre yola were investigated for their aflatoxin content by using the velasco fluorotox...
Congenital diseases account for a large portion of pediatric illness. Prenatal screening and diagnosis permit early detection of many genetic diseases. Fetal therapeutic strategies to manage disease processes in utero represent a powerful new approach for clinical care. A safe and effective fetal pharmacotherapy designed to modulate gene expression ideally would avoid direct mechanical engageme...
Previous studies have shown that antibodies to cubulin, a receptor on the yolk sac that binds high density lipoproteins (HDL) and cobalamin, induce fetal abnormalities. Mice with markedly low concentrations of plasma HDL-cholesterol (HDL-C) give birth to healthy pups, however. To establish whether maternal HDL-C has a role in fetal development, sterol metabolism was studied in the fetus and ext...
Rare nucleated fetal cells circulate within maternal blood. Noninvasive prenatal diagnosis by isolation and genetic analysis of these cells is currently being undertaken. We sought to determine if genetic evidence existed for persistent circulation of fetal cells from prior pregnancies. Venous blood samples were obtained from 32 pregnant women and 8 nonpregnant women who had given birth to male...
Hypoxia is necessary for fetal development; however, excess hypoxia is detrimental. Hypoxia has been extensively studied in the near-term fetus, but less is known about earlier fetal effects. The purpose of this study was to determine the window of vulnerability to severe hypoxia, what organ system(s) is most sensitive, and why hypoxic fetuses die. We induced hypoxia by reducing maternal-inspir...
To develop monoclonal reagents for antigenic analysis and serotyping of Campylobacter spp., hybridoma cell lines were produced by fusion of mouse myeloma cells and spleen cells from mice immunized with Formalin-treated Campylobacter jejuni organisms. An enzyme immunoassay was used for preliminary screening of the cell culture supernatants and ascites. Twenty-nine clones which reacted with the i...
Leptin is a 167-aa protein that is secreted from adipose tissue and is important in the regulation of energy balance. It also functions in hematopoiesis and reproduction. To assess whether leptin is involved in fetal growth and development we have examined the distribution of mRNAs encoding leptin and the leptin receptor (which has at least six splice variants) in the 14.5-day postcoitus mouse ...
the thyroid structural changes in pregnant ewes and their fetuses were investigated. out of 100 pairs of thyroid glands collected from ewes and their fetuses at the local municipal abattoir in ahvaz city of khuzestan province, multiple lesions were seen in 59% and 21% of the thyroid glands of ewes and fetuses, respectively. histologically, ninety nine lesions in the ewes and twenty two lesions ...
