Methadone metabolism in placentas from preterm pregnancies
The aim of this investigation is to identify and characterize the enzyme system responsible for the N-demethylation of methadone in human preterm placentas. The metabolism of methadone revealed typical Michaelis-Menten saturation kinetics. Methadone was N-demethylated to EDDP, only, by human …

Ambulatory blood pressure monitoring in hypertensive pregnancies
… pregnancy. An extensive database of hypertensive pregnancies is then analysed to assess outcomes in a local multi-ethnic population. Women with chronic hypertension are examined separately. Very high rates of stillbirth are evident, especially in women of Asian and Black ethnicity with …

Placental angiogenesis and immune-privilege in normal and pathological pregnancies
… EGF and VEGF were conducted in normal and in pregnancies complicated by PE and IUGR. Angiogenin was identified for the first time to be produced in a gestation dependent manner with significantly increased levels of expression and secretion in PE and IUGR. On the other hand, levels of VCAM-1 …

Molecular Pathology: Potential Biomarkers For The Detection Of Down Syndrome Pregnancies
… to identify pos- sible new biomarkers for DS pregnancies and investigate the potential use of PRSS56 and SPINK7 proteins as two new target biomarkers for DS. We will also use multiplex droplet digital PCR (ddPCR) using cell-free fetal DNA (cffDNA) to target different genes on chromosomes 21, …
