BACKGROUND For the primary prevention of neural tube defects (NTDs), public health authorities recommend women of childbearing age to take 400 mug folic acid/d 4 wk before conception and during the first trimester. The biologically active derivate [6S]-5-methyltetrahydrofolate ([6S]-5-MTHF) could be an alternative to folic acid. OBJECTIVE We investigated(More)
Treatment with carbamazepine (CBZ) affects cholesterol concentrations, but little is known about the precise nature and underlying mechanisms of changes in lipoprotein metabolism. We investigated prospectively the effects of CBZ on lipid metabolism in normolipemic adults. In 21 healthy males, lipoprotein and noncholesterol sterol concentrations were(More)
BACKGROUND A maternal red blood cell (RBC) folate concentration > 906 nmol/L is thought to be optimal for lowering the risk of neural tube defects (NTDs) in pregnancy. Whereas the appearance of folate in RBCs has been followed during folic acid supplementation, data on elimination kinetics are not yet available. OBJECTIVE The aim of our investigation was(More)
BACKGROUND The lowest risk of having a child with a neural tube defect (NTD) was related to red blood cell (RBC) folate concentrations of >906 nmol/L. For NTD prevention, it is recommended that women use periconceptional supplementation of 400 microg/day folic acid. Using this dose previous studies indicate that RBC folate >906 nmol/L was not reached within(More)
Statins decrease apoB-100-containing lipoproteins by increasing their fractional catabolic rates through LDL receptor-mediated uptake. Their influence on hepatic secretion of these lipoproteins is controversial. The objective of the study was to examine the influence of simvastatin on the secretion of apoB-100-containing lipoproteins in fasting non-obese(More)
