. 2001 Jun;
200(3):155-68.
PMID: 11426667
Hyperhomocyst(e)inemia is commonly accepted as an independent atherosclerotic risk factor. In most hemodialysis patients, serum homocyst(e)ine is markedly elevated and may contribute to premature atherosclerosis in these patients. Whereas the...

47(1):30-5.
PMID: 11244289
Background: In the elderly, deficiencies of folate, cobalamin (vitamin B(12)) and pyridoxal phosphate (vitamin B(6)) are common. The metabolites homocysteine, methylmalonic acid, 2-methylcitric acid and cystathionine have been reported to...

. 2000 Sep;
35(8):866-72.
PMID: 10994627
