Hormone Research in Paediatrics, 1994
1997 marks the 25th anniversary of the discovery of the master circadian pacemaker in mammals in the hypothalamic suprachiasmatic nucleus. Remarkable progress has been made over the last 25 years in elucidating the physiological mechanisms involved in the entrainment, generation and expression of circadian rhythms at the cellular and systems levels ...

In this chapter, we will discuss mathematical models of the master circadian rhythm in the suprachiasmatic nucleus of the hypothalamus with a particular emphasis on models that incorporate the effect of light on circadian phase resetting and melatonin suppression.

The American Journal of Medicine, 1988
All forms of life, from the simplest cells to the most complex organisms, show periodicity in some of their biologic activities and functions. The most common of these rhythmic events are those that we refer to as "circadian" (circa, around; dias, day).

Circadian biomarkers, circadian genes and bipolar disorders
Journal of Physiology-Paris, 2011Bipolar disorders are associated with circadian deregulations both during acute mood episodes and during euthymic periods, suggesting that these circadian rhythms may represent trait markers of the disease. Several arguments demonstrate that deregulations of circadian rhythms may be part of the pathophysiology of bipolar disorders.

A role of the circadian system and circadian proteins in aging
Ageing Research Reviews, 2007Circadian rhythms are genetically determined biological rhythms that are considered an important adaptive mechanism to the cyclical light/dark alterations in the Earth environment. Age-related changes in the circadian time-keeping mechanism are well known, and seemingly contribute to various pathologies of aging.
