Homocysteine.
Langman LJ, Cole DE. Langman LJ, et al. Crit Rev Clin Lab Sci. 1999 Aug;36(4):365-406. doi: 10.1080/10408369991239231. Crit Rev Clin Lab Sci. 1999. PMID: 10486705 Review.
Plasma should be separated shortly after collection to avoid artifactual increases due to synthesis by blood cells in vitro. tHcy concentrations must be interpreted in light of the fact that serum albumin, urate, creatinine, and vitamin concentrations may be …

Folate status assessment.
Bailey LB. Bailey LB. J Nutr. 1990 Nov;120 Suppl 11:1508-11. doi: 10.1093/jn/120.suppl_11.1508. J Nutr. 1990. PMID: 2243297 Review.
The first stage of folate depletion can be assessed by measuring serum folate levels, which drop prior to tissue depletion, and which are paralleled by a reduction in red blood cell (RBC) folate. ...Cell division, including erythropoiesis, becomes impa …

Folate status and health: challenges and opportunities.
Obeid R, Oexle K, Rißmann A, Pietrzik K, Koletzko B. Obeid R, et al. J Perinat Med. 2016 Apr;44(3):261-8. doi: 10.1515/jpm-2014-0346. J Perinat Med. 2016. PMID: 25825915 Free article. Review.
The prevalence of neural tube defects (NTDs) has been significantly lowered in more than 70 countries worldwide by applying fortification with folic acid. Periconceptional supplementation of folic acid also reduces the risk of congenital heart d …

Homocysteine and pregnancy.
Hague WM. Hague WM. Best Pract Res Clin Obstet Gynaecol. 2003 Jun;17(3):459-69. doi: 10.1016/s1521-6934(03)00009-9. Best Pract Res Clin Obstet Gynaecol. 2003. PMID: 12787538 Review.
Homocysteine is an amino acid that is involved in several key metabolic processes, including the methylation and sulphuration pathways. Blood concentrations of homocysteine are determined by various dietary factors, including folic acid and vita …

Vitamin neurotoxicity.
Snodgrass SR. Snodgrass SR. Mol Neurobiol. 1992 Spring;6(1):41-73. doi: 10.1007/BF02935566. Mol Neurobiol. 1992. PMID: 1463588 Review.
Vitamins contain reactive functional groups necessary to their established roles as coenzymes and reducing agents. Their reactive potential may produce injury if vitamin concentration, distribution, or metabolism is altered. However, identification of vitamin toxicity has …

Folate metabolism and requirements.
Bailey LB, Gregory JF 3rd. Bailey LB, et al. J Nutr. 1999 Apr;129(4):779-82. doi: 10.1093/jn/129.4.779. J Nutr. 1999. PMID: 10203550 Review.
Estimates of folate requirements have been based on intakes associated with maintenance of normal plasma and erythrocyte folate concentrations and functional tests that reflect abnormalities in folate-dependent reactions. Dietary Reference Intak …

Epilepsy and pregnancy.
O'Brien MD, Gilmour-White S. O'Brien MD, et al. BMJ. 1993 Aug 21;307(6902):492-5. doi: 10.1136/bmj.307.6902.492. BMJ. 1993. PMID: 8400940 Free PMC article. Review.
The commonest fetal malformations are cleft lip and palate and congenital heart disease, usually septal defects. These abnormalities may be caused by all the major antiepileptic drugs. ...Present evidence suggests that carbamazepine is the safest drug. Folic
