During the last 20 years, numerous clinical trials have examined the therapeutic usefulness
of melatonin in different fields of medicine. The objective of this article is to review, in depth …

Background: Melatonin synchronizes central but also peripheral oscillators (fetal adrenal
gland, pancreas, liver, kidney, heart, lung, fat, gut, etc.), allowing temporal organization of …

Melatonin is an indole hormone that is produced by the pineal gland, mainly at night, with a
peak around 3.00 am under normal environmental conditions. This endogenic secretion …

Melatonin (MLT) is a methoxyindole secreted principally by the pineal gland. It is
synthesized at night under normal environmental conditions. The endogenous rhythm of …

Melatonin is synthesized and secreted by the pineal gland during the dark period of the light-
dark cycle. This rhythmic nocturnal melatonin secretion is generated directly by the circadian …

Melatonin signals time of day and time of year in mammals by virtue of its pattern of
secretion, which defines 'biological night.'It is supremely important for research on the …

Melatonin, a hormone produced primarily by the pineal gland, is also secreted from the gut
and eye during darkness. There are three classes of melatonin receptors, MT< sub> 1, MT< …

Melatonin is synthesized and secreted during the dark period of the light-dark cycle. Thus,
melatonin has an obvious association with sleep, at least in diurnal animals. Rhythmic …
