The outdoor air pollution and brain health workshop.
Accumulating evidence suggests that outdoor air pollution may have a significant impact on central nervous system (CNS) health and disease. To address this issue, the National Institute ofExpand

Correlation of brain magnetic resonance imaging changes with pallidal manganese concentrations in rhesus monkeys following subchronic manganese inhalation.
High-dose manganese exposure is associated with parkinsonism. Because manganese is paramagnetic, its relative distribution within the brain can be examined using magnetic resonance imaging (MRI).Expand

Manganese Dosimetry: Species Differences and Implications for Neurotoxicity
Abstract Manganese (Mn) is an essential mineral that is found at low levels in food, water, and the air. Under certain high-dose exposure conditions, elevations in tissue manganese levels can occur.Expand

Tissue manganese concentrations in young male rhesus monkeys following subchronic manganese sulfate inhalation.
High-dose human exposure to manganese results in manganese accumulation in the basal ganglia and dopaminergic neuropathology. Occupational manganese neurotoxicity is most frequently linked withExpand

Cytochrome oxidase inhibition induced by acute hydrogen sulfide inhalation: correlation with tissue sulfide concentrations in the rat brain, liver, lung, and nasal epithelium.
Hydrogen sulfide (H2S) is an important brain, lung, and nose toxicant. Inhibition of cytochrome oxidase is the primary biochemical effect associated with lethal H2S exposure. The objective of thisExpand

Neurotoxicity of manganese chloride in neonatal and adult CD rats following subchronic (21‐day) high‐dose oral exposure
The purpose of this study was to evaluate the relative sensitivity of neonatal and adult CD rats to manganese‐induced neurotoxicity. Identical oral manganese chloride (MnCl2) doses (0, 25, or 50 mgExpand

Analysis of manganese tracer kinetics and target tissue dosimetry in monkeys and humans with multi-route physiologically based pharmacokinetic models.
Manganese (Mn) is an essential nutrient with the capacity for toxicity from excessive exposure. Accumulation of Mn in the striatum, globus pallidus, and other midbrain regions is associated withExpand

Pharmacokinetics of inhaled manganese phosphate in male Sprague-Dawley rats following subacute (14-day) exposure.
Methylcyclopentadienyl manganese tricarbonyl (MMT) is used as a gasoline octane enhancer. Manganese phosphate is the primary respirable (PM(2.5)) MMT-combustion product emitted from the automobileExpand

Application of pharmacokinetic data to the risk assessment of inhaled manganese.
There is increased interest within the scientific community concerning the neurotoxicity of manganese owing in part to the use of methylcyclopentadienyl manganese tricarbonyl (MMT) as a gasoline fuelExpand
