Both bright light and melatonin have successfully been used in laboratory and field settings to "phase advance" (resetting the circadian clock earlier in time so that all the circadian rhythms of the body occur earlier) thereby helping people adapt to night shift work or to a new time zone following rapid transmeridian jet travel.
Their findings may help shed light on future treatments for disorders triggered by circadian clock dysfunction, including jet lag, shift work disorders, and chronic conditions like depression and Parkinson's disease.
We may now be glimpsing the core of the circadian clock, but we've only begun to scratch at the surrounding loops.
assistant professor, and his colleagues undertook the first study to establish a relationship between circadian clock gene expression and the growth rate of tumors.
The interval clock, unlike the circadian clock, is something that people can actively control.
The circadian clock is an intrinsic time-tracking system in the human body that anticipates environmental changes and adapts to the appropriate time of day.
Washington, May 21 ( ANI ): Researchers who discovered that mouse hair has a circadian clock - a 24-hour cycle of growth followed by restorative repair - suspect that hair loss in humans from toxic cancer radiotherapy and chemotherapy might be minimized if these treatments are given late in the day.
Many of the body's processes follow a natural daily rhythm or so-called circadian clock that is based on regular sleep-wake cycles.
Experiments with cultured human cells also showed that caffeine competitively bound to adenosine receptors, which disrupted signaling of cyclic adenosine monophosphate (cAMP), a key part of the circadian clock, the researchers said.
Receptors in the eye then send a signal to the body's circadian clock regulator, stopping the secretion of melatonin, which naturally "wakes up" all body systems.

The light can trick a person's biological or circadian clock into thinking it has more time before bed, thus reducing the production of melatonin and disrupting sleep patterns.
Objective: We will investigate the role of the circadian clock in energy balance, metabolism and lifespan of C.
