Pregnant women are one of the most sensitive populations to the toxic effects associated with lead (Pb) exposure. These effects are primarily associated with plasma Pb (Pb-P), which reflects the most rapidly exchangeable fraction of Pb in the bloodstream, and elevated maternal Pb-P may be more relevant to foetal Pb ...

Edema-proteinuria-hypertension-gestosis complex develops in late pregnancy and is usually associated with placenta hypoxia and dysfunction. Leptin, the obsess gene product, is adipocyte-derived hormone that reduces calorie intake and body fat consequently results in weight lost. Recently it had been shown to be synthesized in an secreted form placental trophoblast cells ...

During development from juvenility to adulthood, rats displayed constant vitamin B12, decreasing folic acid and increasing homocysteine levels in blood plasma parallel to decreasing aminopeptidase M activities in the jejunum. The rising homocysteine level with advancing age implies growing metabolic stress and may be seen as cause for the increase ...

Carotenoid pigments are a common source of red, orange, and yellow coloration in vertebrates. Animals cannot manufacture carotenoids and therefore must obtain them in their diet to produce carotenoid-based coloration. Male great frigatebirds (Fregata minor) display a bright red inflated gular pouch as part of their elaborate courtship display. The ...

The rupture of coronary atherosclerotic plaque and subsequent thrombus formation are major events underlying acute coronary syndromes (ACS). Pregnancy associated plasma protein A (PAPP-A) is a member of the metzincin superfamily of metalloproteinases originally identified in the serum of pregnant women. Recent studies indicate that ACS is associated with elevated ...
