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...

In men, sexual orientation correlates with the number of older brothers, each additional older brother increasing the odds of homosexuality by approximately 33%. It is hypothesized that this fraternal birth order effect reflects the progressive immunization of some mothers to Y-linked minor histocompatibility antigens (H-Y antigen) by each succeeding male fetus, and the concomitantly increasing...

The genes provide the major contribution to beta-like globin chain production in the fetal liver of humans. However, the expression of genes in the fetus is a recent evolutionary trend seen only in the primate lineage. In a previous study, it was shown that galago and human genes retain their characteristic stagespecific expression patterns in transgenic mice (galago is expressed exclusively in...

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 ...

background: the diagnosis of toxoplasmosis is most critical in pregnant women who acquire infection during gestation and also in fetuses and newborns who are congenitally infected. this study described the performance of molecular and confirmatory serologic testing for toxoplasma infection in the tissues of human spontaneous aborted fetuses and their mothers' blood. materials and methods: ...

nicotine is an alkaloid by high level of addictive property that can quickly assimilate from smoker’s lung. it passes from the placenta and gathers in the developing fetus. our previous study showed that collagen type iv plays a critical role in basement membrane of different embryonic organs. in this study the effect of maternal nicotine was evaluated by collagen iv changes in lung of mice off...

BACKGROUND The aim of this study was to apply the nested-PCR and bioassay methods in detection and genotyping of Toxoplasma gondii infection in provided sheep aborted fetus samples from Qazvin Province of Iran. METHODS Eighteen sheep aborted fetal samples were studied by nested-PCR-RFLP, histopathological observation and microbiological assay. Bioassay in mice was carried out by inoculating t...
