Different Types of Melatonin Circadian Secretory Rhythms in Some Blind Subjects
Abstract
Six of 10 blind subjects had unusual melatonin circadian secretory patterns. One of these subjects, studied longitudinally, appeared to have a free-running melatonin secretory rhythm with a period of 24.7 h. Another subject, also studied longitudinally, appeared to secrete melatonin during the day (instead of during the night). Therefore, some blind subjects appear to have different types of circadian rhythm abnormalities. These findings along with previous work demonstrating suppression of human melatonin secretion by light suggest that the light-dark cycle may be important in the regulation of the human melatonin circadian secretory rhythm. These findings may stimulate more research on the endocrinological consequences of blindness as well as on the biological effects of light in humans.

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.
