Cumulative Community-Level Lead Exposure and Pulse Pressure: The Normative Aging Study
(National Institute of Environmental Health Sciences, 2007)
Background: Pulse pressure increases with age in industrialized societies as a manifestation of arterial stiffening. Lead accumulates in the vasculature and is associated with vascular oxidative stress, which can promote ...
Lead Concentrations in Relation to Multiple Biomarkers of Cardiovascular Disease: The Normative Aging Study
(National Institute of Environmental Health Sciences, 2012)
Background: Lead exposure has been associated with cardiovascular disease (CVD) in animal and human studies. However, the mechanisms of action have not been fully elucidated. We therefore examined the relationship between ...
Biomarkers of Lead Exposure and DNA Methylation within Retrotransposons
(National Institute of Environmental Health Sciences, 2010)
Background: DNA methylation is an epigenetic mark that regulates gene expression. Changes in DNA methylation within white blood cells may result from cumulative exposure to environmental metals such as lead. Bone lead, a ...
Cumulative Exposure to Lead in Relation to Cognitive Function in Older Women
(National Institute of Environmental Health Sciences, 2008)
Background: Recent data indicate that chronic low-level exposure to lead is associated with accelerated declines in cognition in older age, but this has not been examined in women. Objective: We examined biomarkers of lead ...
Association between hemochromatosis genotype and lead exposure among elderly men: the normative aging study.
Because body iron burden is inversely associated with lead absorption, genes associated with hemochromatosis may modify body lead burden. Our objective was to determine whether the C282Y and/or H63D hemochromatosis gene ...
