Homocysteine, a sulfur amino acid, is an intermediate metabolite of methionine. In 1969, McCully reported autopsy evidence of extensive arterial thrombosis and atherosclerosis in children with elevated plasma homocysteine concentrations and homocystinuria.

Elevated levels of homocysteine (Hcy), a non-proteinogenic amino acid, may lead to a host of manifestations across the biological systems, particularly the nervous system. Defects in Hcy metabolism have been associated with many neurodegenerative diseases including glaucoma, i.e., the leading cause of blindness. However, the pathophysiology of elevated

Homocysteine and familial longevity: the Leiden Longevity Study.
Homocysteine concentrations are a read-out of methionine metabolism and have been related to changes in lifespan in animal models. In humans, high homocysteine concentrations are an important predictor of age related disease.

Effect of Combination Folic Acid, Vitamin B6 , and Vitamin B12 Supplementation on Fracture Risk in Women: A Randomized, Controlled Trial. [PDF]
Epidemiologic studies have demonstrated an association of elevated plasma homocysteine levels with greater bone resorption and fracture risk. Vitamins B12 , B6 , and folic acid are cofactors in homocysteine metabolism, and supplementation with B vitamins

NF-kappaB activation is associated with homocysteine-induced injury in Neuro2a cells
Background Perinatal exposure to hyperhomocysteinemia might disturb neurogenesis during brain development and growth. Also, high levels of homocysteine trigger neurodegeneration in several experimental models.

Evidence Favoring a Positive Feedback Loop for Physiologic Auto Upregulation of hnRNP-E1 during Prolonged Folate Deficiency in Human Placental Cells [PDF]
Background: Previously, we determined that heterogeneous nuclear ribonucleoprotein E1 (hnRNP-E1) functions as an intracellular physiologic sensor of folate deficiency.

Importance of Raised Serum Homocysteine Levels in Ischemic Stroke Patients [PDF]
Background: Around 5.5 million people die from stroke each year, making it the second leading cause of mortality worldwide. Increased homocysteine levels lead to early neurological deteriorations in ischemic stroke and may have an association with other

Influence of homocysteine on the physical structure and molecular mobility of elastin network in cultured arteries [PDF]
The thermal and dielectric properties of the elastin network were investigated in arteries cultured with physiological and pathological concentrations of homocysteine, an aminoacid responsible of histological impairments in human arteries.

Global Burden Related to Nitrous Oxide Exposure in Medical and Recreational Settings: A Systematic Review and Individual Patient Data Meta-Analysis. [PDF]
The risk of adverse effects of nitrous oxide (N2O) exposure is insufficiently recognized despite its widespread use. These effects are mainly reported through case reports. We conducted an individual patient data meta-analysis to assess the prevalence of

Elevated Levels of Methylmalonate and Homocysteine in Parkinson's Disease, Progressive Supranuclear Palsy and Amyotrophic Lateral Sclerosis [PDF]
Background/Aims: Increasing evidence suggests that elevated levels of homocysteine (Hcy) and methylmalonate (MMA) may be involved in the pathogenesis of neurodegenerative diseases. Methods: The urine levels of MMA and serum levels of Hcy as well as folic
