Background and Objective: Iron oxides nanoparticles have numerous applications in medical industry. Nanoparticles are particles with 100 nm in diameter. Despite their various applications, toxic effects of Iron oxide nanoparticles call for supplementary investigations. In this study, the toxic effect of iron oxide nanoparticles on lung development in fetal mice was examined. Materials and Me...

Adult pregnant mice were given i.v. injections of (3H)3-methylcholanthrene (20 muCi in 1.1 mug/mouse) or (14C)3-methylcholanthrene (1.0 muCi in 48 mug/mouse). Ethanol extracts of their tissues were chromatographed on Sephadex LH-20. Three groups of 3-methylcholanthrene metabolites were obtained: one group as yet unidentified, one containing the hydrocarbon and hydroxylated derivatives, and a th...

Perfluorooctanesulfonate (PFOS) is a widely spread environmental contaminant. It accumulates in the brain and has potential neurotoxin effects. Due to chemical properties, PFOS shows persistency in the environment and therefore has potential hazardous effect. The risk of possible intra uterine exposure to PFOS poses a health concern for developmental effects. The goal of this study was survey o...

Azole agents especially Miconazole are widely used even during pregnancy as antifungal agents. The aim of this study was to assess the usefulness of FTIR Micro-Spectroscopy for discriminating of Miconazole treated liver tissue from control liver tissue. The mice were injected with Miconazole (60 mg/Kg) on gestation day 9 and they were dissected on pregnancy day 15. The fetus fixed, dehydrated a...

Microchimerism refers to the status of harboring cells from another individual at low levels. It is well known that cells traffic bidirectionally between fetus and mother during pregnancy. This situation resembles a naturally occurring long lasting fetal stem cell transplantation. The fetus acts as the donor and the mother acts as the recipient. To study the role of microchimerism in tissue reg...

The consequences of viral infection during pregnancy include impact on fetal and maternal immune responses and on fetal development. Transplacental infection in cattle with noncytopathic bovine viral diarrhea virus (ncpBVDV) during early gestation results in persistently infected (PI) fetuses with life-long viremia and susceptibility to infections. Infection of the fetus during the third trimes...
