Hormone Research, 2008
The field of chronobiology, the study of the rhythms in plants and animals, was restricted to botanists for centuries. Only recently during the last decades could research be broadened to include animals and later even human beings. Rhythms have been documented and related to the alternation of day and night and to the succession of the seasons ...

Headache: The Journal of Head and Face Pain, 1998
This study was undertaken to determine whether migraine attacks exhibit circadian, menstrual, or seasonal variations in frequency and, thus, to characterize more precisely this relapsing, remittent pleomorphic disease. An analysis of 3582 well‐documented migraine attacks in 1698 adults was undertaken.

The Pavlovian Journal of Biological Science, 1975
Several fundamental principles of chronobiology are discussed. The importance of biological rhythmicity in (1) the every day interpretation of data, both descriptive and experimental, and (2) the design of scientifically accurate experiments, is the main theme of this presentation.

Mathematical Modeling in Chronobiology
2013Circadian clocks are autonomous oscillators entrained by external Zeitgebers such as light-dark and temperature cycles. On the cellular level, rhythms are generated by negative transcriptional feedback loops. In mammals, the suprachiasmatic nucleus (SCN) in the anterior part of the hypothalamus plays the role of the central circadian pacemaker ...

Journal of Controlled Release, 2001
Traditionally, drug delivery has meant getting a simple chemical absorbed predictably from the gut or from the site of injection. A second-generation drug delivery goal has been the perfection of continuous constant rate (zero-order) delivery of simple xenobiotic molecules or common hormones.

Chronobiology and chronotherapy in medicine
Disease-a-Month, 1995There is a fascinating and exceedingly important area of medicine that most of us have not been exposed to at any level of our medical training. This relatively new area is termed chronobiology; that is, how time-related events shape our daily biologic responses and apply to any aspect of medicine with regard to altering pathophysiology and treatment ...

Chronobiology: Anatomy in time
American Journal of Anatomy, 1983AbstractChronobiology is that branch of science that objectively explos and quantifies mechanisms of biological time structure, including the important rhythmic manifestations of life. It is the study of biological rhythms. This paper introduces chronobiology and some of its vocabulary, principles, and techniques.A circadian rhythm is a regularly ...

Abstract The ability to regulate physiologic functions rhythmically is a phylogenetically ancient adaptation to the change in environment that accompanies the earth’s rotation, and circadian rhythms have been identified in almost all organisms from unicellular algae to primates.
