BACKGROUND: Amyotrophic lateral sclerosis (ALS) of nonmutant superoxide dismutase (SOD) type may be caused by toxicity of the reduced glutathione (GSH) precursors glutamate and cysteine, and sulfite (a metabolite of cysteine), which accumulate when one or more of the enzymes needed for GSH synthesis are defective. OBJECTIVES: A case is ...

Homocysteine (Hcy) is a risk factor for vascular dysfunction. High levels of Hcy may result in vascular injury accelerating atherosclerosis leading to ischemia. After ischemia, endothelial progenitor cells (EPCs) migrate from bone marrow to repair damaged sites either through direct incorporation of EPCs or by repopulating mature endothelial cells. This ...
