Neurotoxicology, 20(2-3), 343-353 (1999-07-01)
Exposure data and bioindicators were obtained for a study whose objective was detection of early manifestations of manganese (Mn) neurotoxicity in a population with potential environmental exposure. The study included persons with no history of neurotoxic workplace exposure in Southwest...

In the crystal structure of Photosystem II (PSII) analyzed at a resolution of 1.9Å, most of the bond lengths between Mn and O atoms in the oxygen-evolving Mn4Ca cluster are 1.8-2.1Å. On the other hand, the Mn1O5 bond in the...

Manganese porphyrins have been extensively investigated as model systems for the natural enzyme cytochrome P450 and as synthetic oxidation catalysts. Here, we report single-molecule studies of the multistep reaction of manganese porphyrins with molecular oxygen at a solid/liquid interface, using...

Excessive manganese (Mn) has been associated with neurobehavioral deficits and neurological and/or neuropsychiatric illness, but the level at which this metal can cause adverse neurotoxic effects, particularly with long-term exposure, is still unknown. The objective of the present study was...
