## Abstract ## BACKGROUND: This study investigated the association of neural tube defects (NTDs) with maternal periconceptional intake of folic acidβcontaining supplements and dietary nutrients, including folate, among deliveries that occurred after folic acid fortification in selected California

Results from experimental animals and other laboratory data have suggested a role for methionine, an essential amino acid, in normal closure of the neural tube. We hypothesized that women who had higher dietary intakes of methionine would be at lower risk for neural tube defect (NTD)-affected pregna
## Abstract **BACKGROUND:** Folic acid supplementation reduces the occurrence of neural tube defects (NTDs); however, it is not clear whether it protects against teratogenic effects of antiepileptic drugs. **METHODS:** We report the cases of four pregnant women receiving valproic acid therapy, who
## Abstract **BACKGROUND:** Although an information campaign concerning periconceptional folic acid supplementation was launched in 1998 in Shanxi Province, China, the prevalence of neural tube defects in rural areas was reported as high as 140 per 10,000 births in 2002. The blood folate concentrat
