Abstract

There is a large body of evidence implicating oxidative damage in the pathogenesis of both normal aging and neurodegenerative diseases. Oxidative damage to proteins has been well established. Although there are a large number of potential oxidative modifications only a few have been systematically studied. The most frequently studied marker of oxidative damage to proteins is protein carbonyl groups. 3-Nitrotyrosine is thought to be a relatively specific marker of oxidative damage mediated by peroxynitrite. Increased concentrations of both protein carbonyls and 3-nitrotyrosine have been documented in both normal aging as well as in Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS). These findings help to provide a rationale for trials of antioxidants in neurodegenerative diseases.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
