the cause of neural tube defects (ntds) is multifactorial and in this case folic acid has an important role. since the neural tube is closed during 21-28 days of pregnancy, most of women are not informed about their pregnancy at this time, and as a result the golden time of folic acid consumption is missed. the aim of this study was evaluating the performance of pregnant women attending to tehr...

influence of folic acid on the cns is still unclear. folate has a neuroprotective effect, while on the other hand excess folate can exacerbate seizures in epileptics. the aim of the present study was to examine the effect of subchronic administration of folic acid on behavioural and electroencephalographic (eeg) characteristics of dl homocysteine thiolactone induced seizures in adult rats. t...

background: gastric cancer is the fourth common malignancy and the second prevalent cause of cancer death in the world. genetic and environmental factors play an important role in the development of this cancer. nutritional and epidemiological studies have indicated that folate status modulates the risk of developing cancer and apoptosis has been reported to play a decisive role in precancerous...

Enzyme induction in Escherichia coli is stimulated by certain 5-amino-2,4-bis(substitutedamino)pyrimidines (Kunkee, 1960a). Other 2,4diaminopyrimidines have been reported to be antagonists of folic acid (Hitchings et al., 1952; Doctor, 1956). Since there are indications that the stimulation of enzyme induction involves nucleic acid metabolism (Kunkee, 1960b) and since folic acid is involved in ...

OBJECTIVE Folic acid food fortification has successfully reduced neural tube defect-affected pregnancies across Canada. The effect of this uncontrolled public health intervention on folate intake among Canadian children is, however, unknown. Our objectives were to determine folic acid intake from food fortification and whether fortification promoted adequate folate intakes, and to describe foli...

Periconceptional use of folic acid alone or in multivitamin supplements is effective for the primary prevention of neural-tube defects. The Hungarian randomized and two-cohort controlled trials showed that periconceptional multivitamin supplementation can reduce the occurrence of some other structural birth defects, i.e. congenital abnormalities. These findings were supported by many, but not a...

Folic acid plays an important role in the prevention of neural tube defects (e.g., spina bifida and anencephaly), heart defects, facial clefts, urinary abnormalities, and limb deficiencies. Milk and milk products serve as a potential source for folic acid fortification because of the presence of folate-binding proteins that seem to be involved in folate bioavailability. Although milk is not a g...

OBJECTIVE Folic acid supplementation during the pre-conception period and first trimester of pregnancy reduces the incidence of neural tube defects (NTDs). In this study, our aim is to investigate knowledge and use of folic acid among women attending our clinic. MATERIAL AND METHODS Between January 2012 and June 2012, 817 participants, consisting of 345 pregnant and 472 non-pregnant women, we...

Objective While the effects of folic acid are well established in prevention of Neural Tube Defects (NTDs), these diseases have a high prevalence in Iran. In order to encourage folic acid supplement use in pregnancy, it is important to promote the awareness of women of childbearing age regarding folic acid importance in preventing NTDs. The aim of the present study was to study the knowledge an...

Folic acid supplementation may prevent the development of cancer in normal tissues but may promote the progression of established (pre)neoplastic lesions. However, whether or not folic acid supplementation can promote the progression of established (pre)neoplastic mammary lesions is unknown. This is a critically important issue because breast cancer patients and survivors in North America are l...
