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.

Hormone Research, 1990
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 ...

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.

Current Opinion in Anaesthesiology, 2007
It has been shown that biological rhythms influence the pharmacology and effects of anaesthetic agents such as local anaesthetics, hypnotics and muscle relaxants. This review discusses the latest findings and their consequences for anaesthesiological practice.

Fibromyalgia: Chronobiological Aspects
Chronobiology International, 1994The primary fibromyalgia syndrome (Weichteilrheumatismus) shows a circadian rhythm of the symptoms and, moreover, a seasonality of pain severeness. Although the pathophysiologic mechanisms are unknown, the circadian variations are well documented in the literature; the seasonality of pain is sometimes clinically reported.

1999
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.

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 ...
