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 ...

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.

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 demographics of the study population accurately

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 OF ASTHMA
Clinics in Chest Medicine, 1995There is no doubt that many pathophysiologic conditions change over a 24-hour period and thus therapy needs to be directed at these changes. In particular, asthma has been one of the better-studied disease processes in regard to circadian changes in pathophysiology. As we continue to learn more about circadian changes, better approaches to treating the

In earlier times, chronobiology and sleep research developed independently. The convergence of these two research areas led to new insight into basic mechanisms of both sleeping and waking. The roots of chronobiology as a science started with observation of rhythmic phenomena in living organism including humans.

Chronotoxicity as Related to Chronobiology
Drug Metabolism and Drug Interactions, 1997This review focuses primarily on the complexities of chronotoxicity and chronopharmacology (time-of-day effects on the metabolism of environmental chemicals and therapeutic agents as related to chronobiology). The nature of the melatonin signal may modify the function of the hepatic endoplasmic reticulum resulting in variations in the metabolism of ...

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 ...
