Melatonin is a ubiquitous molecule present in almost every live being from bacteria to
humans. In vertebrates, besides being produced in peripheral tissues and acting as an …

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

Melatonin, hormone of the pineal gland, is concerned with biological timing. It is secreted at
night in all species and in ourselves is thereby associated with sleep, lowered core body …

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 of great importance to the investigation of human biological rhythms. Its rhythm
in plasma or saliva provides the best available measure of the timing of the internal …

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 …

The role exerted by melatonin in human physiology has not been completely ascertained.
Melatonin levels have been measured in different physiopathological conditions, but the …
