Reduced Monoamine Oxidase Activity in Blood Platelets from Bipolar Depressed Patients

MURPHY, DENNIS L., WEISS, RICHARD·1972·American Journal of Psychiatry

Abstract

Cellular monoamine oxidase (MAO) activity measured in blood platelets is significantly (45 percent) lower in depressed patients with a history of mania (bipolar patients) than in nonbipolar depressed patients and normal controls of similar age and sex. This difference in MAO activity may be related to other biological and psychological characteristics of these patients that suggest that bipolar patients constitute a specific subgroup among patients with affective disorders.

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.
