Recent studies suggest that leptin, the product of the obese gene, is produced by the placenta during pregnancy. The present study addressed the question whether second trimester maternal serum leptin could be altered by fetal Down syndrome or Edwards syndrome. Maternal serum leptin concentrations were measured in 18 pregnancies complicated ...

Chelerythrine, sanguinarine and an alkaloid extract from Macleaya cordata--sanguiritrin--were found to be inhibitors of aminopeptidase A and dipeptidyl peptidase IV, while fagaronine inhibited dipeptidyl peptidase IV only. At 50 microM, chelerythrine, sanguinarine and sanguiritrin inhibited aminopeptidase N by 82%, 82%, 88%, DPP IV by 38%, 62%, 57%, and fagaronine by ...

Pregnancy-associated plasma protein A (PAPP-A) is an important pregnancy protein. PAPP-A exists in pregnancy serum as a heterotetrameric 2:2 complex with the proform of eosinophil major basic protein (proMBP), forming an approximately 500 kDa and called PAPP-A/proMBP. The gene of PAPP-A has been assigned to human chromosome 9q 33.1. PAPP-A ...

Inhibin-related proteins are involved in the control of the feto-maternal communication required to maintain pregnancy. Human placenta, decidua, and fetal membranes are the major sites of production and secretion of activin A, inhibin A and inhibin B in maternal serum, amniotic fluid, and cord blood. The availability of suitable assays ...

Knowledge of the roles of inhibins and activins has progressed rapidly since the development of a specific and sensitive assay that can be used for measurements on human serum and amniotic fluid samples. There is a sound theoretical basis for the role of transforming growth factor-beta family members in inflammatory ...

Marsupial pregnancy differs from that in eutherians in duration, placentation and hormonal profile so much so that maternal recognition of pregnancy may not occur in polyovular marsupials. However, a comparison of gravid and non-gravid uteri reveals differences indicative of histological and physiological adaptations to pregnancy. In the present study, the ...

In pregnant women with low exposure to lead, high intakes of calcium (>2,000 mg/day) decreased the serum concentration of lead, which could potentially minimize fetal exposure to lead. This is twice the amount of calcium recommended for women during pregnancy and approaches the Upper Level for calcium of 2,500 mg/day. ...

Pregnancy-associated plasma protein-A (PAPP-A) has been identified as the insulin-like growth factor (IGF)-dependent IGF-binding protein-4 (IGFBP-4) protease produced by human fibroblasts. Recently, we found that serum proteases induced during human pregnancy cleaved IGFBP-4 in both an IGF-II-dependent and an IGF-II-independent fashion. This study sought to determine whether PAPP-A is the ...

Numerous studies have suggested a significant role of selenium in the prevention of gynecological carcinoma. These were epidemiological and prospective in humans and therapeutic in laboratory animals. However, no studies have been reported regarding the normal serum selenium levels during pregnancy. The maternal total blood volume increases 30-50% during the ...
