AIMS Hyperhomocysteinaemia is an independent risk factor for atherosclerotic vascular disease and is associated with vascular endothelial dysfunction. Homocysteine modulates cellular methylation reactions. P66shc is a protein that promotes oxidative stress whose expression is governed by promoter methylation. We asked if homocysteine induces endothelial p66shc expression via hypomethylation of ...

BACKGROUND High blood lead (Pb) and hyperhomocysteinemia have been found to be associated with cardiovascular disease (CVD). Mean blood Pb and mean plasma homocysteine levels have been reported to be high in Pakistani population. The objective of the present study was to assess the relationship of blood Pb to the risk of hyperhomocysteinemia in a low income urban population of Karachi, Pakistan...

OBJECTIVE There are several studies showing an association between an increase in the plasma levels of homocysteine and the pathogenesis of hypertension. In this study, we assessed normotensive children of hypertensive adult parents to determine whether there is any change in homocysteine levels prior to the onset of hypertension. METHODS A total of 79 normotensive children of essential hyper...

Normal folate, homocysteine, and methyl group metabolism is critical for maintaining optimum health, and perturbations in these mechanisms may lead to a number of pathological conditions such as diabetes, cardiovascular disease, neural tube defects, and cancer. Hyperhomocysteinemia is a condition that occurs when blood plasma concentrations of homocysteine exceed 15μM and has been implicated as...

Background: Dental implants have been a part of our lives since 1965 when studies Branemark commenced. Today, ever increasing number dental in total or partial edentulous patients provides an outstanding treatment alternative to conventional prosthetic rehabilitation all around the world. However, widespread use has brought alone gradually condition called “disease peri-implant tissues”. The pr...

OBJECTIVE: C-reactive protein (CRP) and homocysteine are markers of cardiovascular risk that may have inflammatory effects. HMG coenzyme A reductase inhibitors (statins) have anti-inflammatory effects in vitro, but it is not clear if such responses in vivo are secondary to lipid lowering. We examined the hypothesis that CRP and homocysteine would stimulate cytokine release in human whole blood ...

Inflammation and cardiovascular disease are associated with elevated serum levels of C-Reactive Protein (CRP) and homocysteine. The presence of both molecules in saliva provides an opportunity for development of non-invasive assessments of disease risk. However, salivary CRP and homocysteine reference ranges and their correlation with serum levels are unknown. This study investigated if CRP and...

BACKGROUND/OBJECTIVES Cardiovascular diseases is a major cause of death and is responsible for 23.8% of deaths in Korea. Clinical symptoms manifest in adulthood, but susceptibility begins in utero. Elevated homocysteine levels and adiposity might be linked to a greater risk in children as well as adults. We hypothesized that those who have simultaneous risk for folate and adiposity would be aff...

Hyperhomocysteinemia is a risk factor for atherosclerosis and thrombosis and is inversely related to plasma folate and vitamin B12 levels. We assessed the effects of vitamin supplementation on plasma homocysteine levels in 89 patients with a history of recurrent venous thrombosis and 227 healthy volunteers. Patients and hyperhomocysteinemic (homocysteine level >16 micromol/L) volunteers were ra...

Back ground: Serum concentrations of homocysteine decrease during normotensive pregnancy, but increases in pre-eclampsia like some other pregnancy complications. Hyperhomocysteinemia has been hypothesized to be associated with placental micro vascularization disease. Objectives: To evaluate the concentration of maternal &umbilical homocysteine in pre-eclamptic women in comparison with that of n...
