Performance evaluation of nine hormone assays on the Immulite 2000 immunoassay system.

abstract：BACKGROUND:A large body of evidence suggests that not only cerebral but also systemic oxidative stress (OxS) might be involved in the pathogenesis of late onset Alzheimer's disease (LOAD) and vascular dementia (VAD), as well as of the prodromal phase of dementia, the so-called mild cognitive impairment (MCI). In the pr...
