Melatonin, light and chronobiological disorders.

Ciba Foundation symposium, 1985
Human plasma melatonin concentrations can be measured accurately and sensitively by gas chromatography-negative chemical ionization mass spectrometry. With this assay, we have shown that: in rats and in humans, plasma melatonin is exclusively derived from the pineal gland; propranolol and clonidine reduce melatonin levels in human; some blind people ...

Chronobiological Disorders: Current and Prevalent Conditions

Journal of Occupational Rehabilitation, 2009
In recent decades, the hectic lifestyle of industrialized societies has wrought its effects on the quality of sleep, and these effects are evidenced by a profusion of sleep-related disorders. Regular exposure to artificial light, coupled with social and economic pressures have shortened the time spent asleep. Otherwise, Circadian Rhythm Sleep Disorders

Nocturnal Headache-Hypertension Syndrome: A Chronobiologic Disorder

Chronobiology International, 1992
The study of blood pressure (BP) monitoring in essential hypertensive patients recurrently suffering from nocturnal headache revealed a rhythmic elevation of sphygmomanometric values during the night. Such a finding was not detected in essential hypertensive patients suffering from occasional headache.

Clinical Chronobiology: Circadian Rhythms in Health and Disease

Seminars in neurology
Circadian rhythms (CRs) are entrainable endogenous rhythms that respond to external stimuli and regulate physiological functions. The suprachiasmatic nucleus (SCN) in the hypothalamus is the mammalian master clock that synchronizes all other tissue ...

Relevance of the Chronobiological and Non-chronobiological Actions of Melatonin for Enhancing Therapeutic Efficacy in Neurodegenerative Disorders

Recent Patents on Endocrine, Metabolic & Immune Drug Discovery, 2011
Melatonin is an indolamine with a large spectrum of functions that can be divided into chronobiotic and nonchronobiotic. Chronobiotic effects are mediated by the daily rhythm of melatonin in the plasma due to nocturnal pineal synthesis, whereas the melatonin produced by other cells, such as gastrointestinal and immune competent cells, is independent of

Chronobiologic treatments for mood disorders

Chronotherapeutics are nonpharmacologic interventions whose development stems from investigations into sleep and circadian rhythm abnormalities associated with mood disorder. These therapies utilize controlled exposure to environmental cues (light, darkness) to regulate biologic rhythms.
