Aromatic Amino Acids and Modification of Parkinsonism

Cotzias, George C., Van Woert, Melvin H., Schiffer, Lewis M.·1967·New England Journal of Medicine

Abstract

THE known biochemical abnormalities in Parkinson's disease consist of a decrease of melanin pigment in the substantia nigra1 , 2 and a decrease of some biogenic amines in the substantia nigra and the corpus striatum.3 These 2 defects might be interrelated, as suggested by the fact that in both melanocytes4 and sympathetic cells5 tyrosine is hydroxylated to dihydroxyphenylalanine, a common precursor in the synthesis of both melanin and catecholamines. Furthermore, both melanocytes and sympathetic cells originate from the neural crest.6 It was suggested earlier7 , 8 that the interrelations between melanogenesis and extrapyramidal disease might be of fundamental importance. It was noted that chronic . . .

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.
