BACKGROUND Few prospective studies have evaluated the influence of arsenic methylation capacity on cardiovascular disease (CVD) risk. OBJECTIVE We evaluated the association of arsenic exposure from drinking water and arsenic methylation capacity with CVD risk. METHOD We conducted a case-cohort study of 369 incident fatal and nonfatal cases of CVD,(More)
BACKGROUND Limited data are available on smoking-related mortality in low-income countries, where both chronic disease burden and prevalence of smoking are increasing. METHODS Using data on 20,033 individuals in the Health Effects of Arsenic Longitudinal Study (HEALS) in Bangladesh, we prospectively evaluated the association between tobacco smoking and(More)
BACKGROUND Occupational exposure to nickel (Ni) is associated with an increased risk for lung and nasal cancers. Ni compounds exhibit weak mutagenic activity, cause gene amplification, and disrupt cellular epigenetic homeostasis. However, the Ni-induced changes in global histone modification levels have only been tested in vitro. OBJECTIVE This study was(More)
Liprin-α4 was strongly induced following nickel (II) chloride exposure in a variety of cell types including BEAS-2B, A549, BEP2D and BL41 cells. Liprin-α4, a member of the Liprin alpha family, has seven isoforms but only three of these variants were detected in BEAS-2B cells (004, 201 and 202). The level of Liprin-α4 variants 201 and 004 were highly(More)
BACKGROUND Arsenic exposure from drinking water has been associated with heart disease; however, underlying mechanisms are uncertain. OBJECTIVE We evaluated the association between a history of arsenic exposure from drinking water and the prolongation of heart rate-corrected QT (QTc), PR, and QRS intervals. METHOD We conducted a study of 1,715(More)
Mechanistic evidence suggests that arsenic exposure from drinking water increases the production of reactive oxygen species and influences inflammatory responses and endothelial nitric oxide homeostasis. These arsenic-induced events may lead to endothelial dysfunction that increases the risk of atherosclerosis and cardiovascular disease. We reviewed(More)
BACKGROUND Epidemiologic data on genetic susceptibility to cardiovascular effects of arsenic exposure from drinking water are limited. OBJECTIVE We investigated whether the association between well-water arsenic and cardiovascular disease (CVD) differed by 170 single nucleotide polymorphisms (SNPs) in 17 genes related to arsenic metabolism, oxidative(More)
BACKGROUND Cross-sectional studies have shown associations between arsenic exposure and prevalence of high blood pressure; however, studies examining the relationship of arsenic exposure with longitudinal changes in blood pressure are lacking. METHOD We evaluated associations of arsenic exposure in relation to longitudinal change in blood pressure in(More)
BACKGROUND Inorganic arsenic exposure has been related to the risk of increased blood pressure based largely on cross-sectional studies conducted in highly exposed populations. Pregnancy is a period of particular vulnerability to environmental insults. However, little is known about the cardiovascular impacts of arsenic exposure during pregnancy. (More)
BACKGROUND Taurine (2-aminoethanesulfonic acid), a conditionally essential sulfur-containing amino acid, is mainly obtained from diet in humans. Experimental studies have shown that taurine's main biological actions include bile salt conjugation, blood pressure regulation, anti-oxidation, and anti-inflammation. METHODS We conducted a prospective(More)
