Health Effects Of Jet Lag Night Shift
2014-01-21 14:07:33

Lee Rannals for redOrbit.com - Your Universe Online Sleep and systems biology researchers from the University of Surrey found that jet lag or working the late shift could have a significant impact on health. Researchers placed 22 participants on a 28-hour day schedule, delaying their sleep-wake cycle by four hours each day until sleep occurred during the middle of the day. The team then collected blood samples to measure the participants' rhythms of gene expression. The...

Researchers at the University of Cincinnati (UC) have identified key molecular components linking circadian rhythms and cell division cycles in Neurospora crassa, providing insights that could lead to improved disease treatments and drug delivery. The researchers in the UC College of Medicine Department of Molecular and Cellular Physiology, led by Christian Hong, PhD, published their findings Monday, Jan. 13, online ahead of print in PNAS (Proceedings of the National Academy of Sciences)....

Reprogramming of liver ‘clock’ may contribute to metabolic disorders A high-fat diet affects the molecular mechanism controlling the internal body clock that regulates metabolic functions in the liver, UC Irvine scientists have found. Disruption of these circadian rhythms may contribute to metabolic distress ailments, such as diabetes, obesity and high blood pressure. There’s good news, though. The researchers also discovered that returning to a balanced, low-fat diet normalized...

Tricking Algae's Biological Clock Boosts Production Of Drugs And Biofuels
2013-11-07 13:15:53

Vanderbilt University Tricking algae's biological clock to remain in its daytime setting can dramatically boost the amount of valuable compounds that these simple marine plants can produce when they are grown in constant light. That is the conclusion of a "proof of concept" experiment described in the Dec. 2 issue of the journal Current Biology. The study found that when the biological clocks of cyanobacteria (blue-green algae) were stopped in their daylight setting, the amount of...

Internal Clock Helps Marine Animals Follow The Tides
2013-09-26 15:39:27

Lee Rannals for redOrbit.com - Your Universe Online Marine animals have an internal clock to help them keep up with their schedules, according to findings published in the journals Current Biology and Cell Reports. The new findings suggest that these animals may be using these clocks as standard operating equipment. "The discovery of the circadian clock mechanisms in various terrestrial species from fungi to humans was a major breakthrough for biology," says Charalambos Kyriacou of the...

Discovery Of ‘Molecular Brakes’ Could Lead To Possible Cure For Jet Lag
2013-08-31 07:10:59

redOrbit Staff & Wire Reports – Your Universe Online Researchers have reportedly located a biological trigger for jet lag -- a discovery that could lead to the development of new drugs designed to help people recover more quickly from travel into new time zones. Writing in the August 29 edition of the journal Cell, the study’s authors explain they have pinpointed a protein known as SIK1, which apparently plays a key role in preventing the body’s internal circadian clock from...

How Is Protein Synthesis Controlled In The Brain Clock?
2013-08-22 05:21:41

April Flowers for redOrbit.com - Your Universe Online Many factors keep us from getting a good night’s sleep. Prime culprits include overnight flights across the ocean, graveyard shifts, and stress-induced insomnia. A new study from McGill and Concordia Universities gives hope, however, that these common sleep disturbances may one day be put to bed. The Earth’s rotation is responsible for creating day and night, and the daily rhythms of all living beings. Mammals have a “circadian...

A team from UNIGE has developed a biotechnology that can be used in many biomedical sectors Most of our physiological functions fluctuate throughout the day. They are coordinated by a central clock in the brain and by local oscillators, present in virtually every cell. Many molecular gearwheels of this internal clock have been described by Ueli Schibler, professor at the Faculty of Science of the University of Geneva (UNIGE), Switzerland. To study how the central clock synchronizes...

Gladstone-led study sheds light on molecular basis for metabolic health and disease Inside each of us is our own internal timing device. It drives everything from sleep cycles to metabolism, but the inner-workings of this so-called "circadian clock" are complex, and the molecular processes behind it have long eluded scientists. But now, researchers at the Gladstone Institutes have discovered how one important protein falls under direct instructions from the body's circadian clock....
