The Circadian Clock and Obesity
2022The modern way of life has dramatically affected our biological rhythms. Circadian rhythms, which are generated by an endogenous circadian clock, are observed in a large number of physiological functions including metabolism. Proper peripheral clock synchronization by different signals including appropriate feeding/fasting cycles is essential to ...

The Bulletin of Mathematical Biophysics, 1967
An extension of an earlier model simulating the effects of light on the drosophila eclosion rhythm is presented. The effects of variable light intensity are described. This allows not only the simulation of certain experiments not covered by the earlier model, but also it permits an extension of the model to other organisms.

Current Opinion in Genetics & Development, 2003
Organisms populating the earth are under the steady influence of daily and seasonal changes resulting from the planet's rotation and orbit around the sun. This periodic pattern most prominently manifested by the light-dark cycle has led to the establishment of endogenous circadian timing systems that synchronize biological functions to the environment.

Circulation Research
The timing of life on Earth is remarkable: between individuals of the same species, a highly similar temporal pattern is observed, with shared periods of activity and inactivity each day. At the individual level, this means that over the course of a single day, a person alternates between two states.

The circadian clock and metabolism
Clinical Science, 2010Mammals have developed an endogenous circadian clock located in the SCN (suprachiasmatic nuclei) of the anterior hypothalamus that responds to the environmental light–dark cycle. Human homoeostatic systems have adapted to daily changes in a way that the body anticipates the sleep and activity periods.

Circadian clocks: Not your grandfather’s clock
Science, 2016The last 20 years have seen the rapid evolution of our understanding of the molecular genes and networks that enable almost all forms of life to generate 24-hour—or circadian—rhythms. One finding has been particularly exciting: that the molecular circadian clock resides in almost all of the cells of the body and that the clock regulates the timing of ...

Circadian Clocks and Metabolism
2009The processes that underlie circadian timekeeping and the regulation of metabolic homeostasis are tightly and reciprocally linked. It is no surprise that many aspects of modern lifestyle such as sleep curtailment, shift work and artificial lighting simultaneously affect the clock and metabolic control.
