Circadian Rhythm News and Research RSS Feed - Circadian Rhythm News and Research

Circadian Rhythm is the regular recurrence, in cycles of about 24 hours, of biological processes or activities, such as sensitivity to drugs and stimuli, hormone secretion, sleeping, feeding, etc. This rhythm seems to be set by a 'biological clock' which seems to be set by recurring daylight and darkness.
Space missions affect sleep patterns in astronauts

Space missions affect sleep patterns in astronauts

The most comprehensive study of sleep patterns during spaceflight has just been published and confirms that astronauts suffer considerable sleep deficiency during both pre-mission training and spaceflight. [More]
Altering the circadian rhythm: an interview with Dr. Doug Kojetin, The Scripps Research Institute

Altering the circadian rhythm: an interview with Dr. Doug Kojetin, The Scripps Research Institute

The circadian rhythm is affected by many different stimuli—such as sleep and light, which are the most broadly appreciated ways—but also eating— all of which can modulate, or change, important processes in our bodies such as temperature, production of hormones or other signalling small molecules, cellular regeneration, and others.

1 in 2 mums still excessively sleepy 4 months after giving birth

New mums are being urged to be cautious about returning to work too quickly, after a QUT study found one in two were still excessively sleepy four months after giving birth. [More]
Scientists study how artificial light influences biological clock

Scientists study how artificial light influences biological clock

Researchers at Inserm, led by Claude Gronfier (Inserm Unit 846: Stem Cell and Brain Institute), have, for the first time, conducted a study under real conditions on the body clocks of members of the international polar research station Concordia. [More]
Lipoic acid appears to reset and synchronize circadian rhythms

Lipoic acid appears to reset and synchronize circadian rhythms

Researchers have discovered a possible explanation for the surprisingly large range of biological effects that are linked to a micronutrient called lipoic acid: It appears to reset and synchronize circadian rhythms, or the "biological clock" found in most life forms. [More]
Scientists discover new role for pair of compounds which alter circadian rhythm

Scientists discover new role for pair of compounds which alter circadian rhythm

Scientists from the Florida campus of The Scripps Research Institute (TSRI) have discovered a surprising new role for a pair of compounds—which have the potential to alter circadian rhythm, the complex physiological process that responds to a 24-hour cycle of light and dark and is present in most living things.

Researchers examine link between full moon and sleep

A Swiss research study conducted last year showed that the full moon affects sleep. The findings demonstrated that people average 20 minutes less sleep, take five minutes longer to fall asleep and experience 30 minutes more of REM sleep, during which most dreaming is believed to occur. [More]

Vanda’s HETLIOZ MAA for Non-24-Hour Sleep-Wake Disorder accepted for evaluation by the EMA

Vanda Pharmaceuticals Inc. announced today that its Marketing Authorization Application (MAA) for oral HETLIOZ™ (tasimelteon) capsules has been accepted for evaluation by the European Medicines Agency (EMA) for the treatment of Non-24-Hour Sleep-Wake Disorder (Non-24). [More]
Protein complex structure that plays an important role in regulating circadian rhythm identified

Protein complex structure that plays an important role in regulating circadian rhythm identified

Structural biologists have made important progress towards better understanding the functioning of the circadian clock. The circadian or inner clock coordinates the sleep-wake rhythm and many other body processes that regulate, for example, metabolism, blood pressure, and the immune system. [More]
Scientists discover link between circadian clock disturbances and inflammatory diseases

Scientists discover link between circadian clock disturbances and inflammatory diseases

A disruption of circadian rhythms, when combined with a high-fat, high-sugar diet, may contribute to inflammatory bowel disease and other harmful conditions, according to a recent study conducted by researchers at Rush University Medical Center. [More]

Biologists identify how T-type channels change electrochemical signaling of heart and brain cells

Biologists identify how T-type channels change electrochemical signaling of heart and brain cells

Biologists have discovered how an outer shield over T-type channels change the electrochemical signaling of heart and brain cells. Understanding how these shields work will help researchers eventually develop a new class of drugs for treating epilepsy, cardiovascular disease and cancer. [More]
New high-throughput method offers rapid whole-brain imaging at single cell resolution

New high-throughput method offers rapid whole-brain imaging at single cell resolution

A major challenge of systems biology is understanding how phenomena at the cellular scale correlate with activity at the organism level. A concerted effort has been made especially in the brain, as scientists are aiming to clarify how neural activity is translated into consciousness and other complex brain activities. [More]
Circadian dysfunction blamed for sleepiness in PD patients

Circadian dysfunction blamed for sleepiness in PD patients

Patients with Parkinson’s disease, particularly those with excessive daytime sleepiness, have reduced melatonin levels and amplitude of the melatonin circadian rhythm, research shows. [More]
Tips to ease daylight saving time transition

Tips to ease daylight saving time transition

Daylight saving time begins at 2 a.m. on Sunday, March 9, bringing more sunshine in the evenings at the price of an hour of sleep. Vanderbilt Sleep Disorders Center specialist Kelly Brown, M.D., says a little extra planning can alleviate that groggy feeling that often accompanies the time change. [More]
