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.

New study aims to find the genetic causes of substance addiction

A new study aims to find the genetic causes specific symptoms of substance addiction, which could lead to a more nuanced way of looking at substance abuse, and ways to treat it. [More]
Discovery of molecular reset button for internal body clock could help treat different disorders

Discovery of molecular reset button for internal body clock could help treat different disorders

An international team of scientists has discovered what amounts to a molecular reset button for our internal body clock. Their findings reveal a potential target to treat a range of disorders, from sleep disturbances to other behavioral, cognitive, and metabolic abnormalities, commonly associated with jet lag, shift work and exposure to light at night, as well as with neuropsychiatric conditions such as depression and autism.

New Johns Hopkins mobile app educates care providers on improving sleep, overall health of patients

Experts from the Johns Hopkins Center for Sleep hope to help patients get a better night’s sleep by providing health care staff members with a basic educational tool on their smartphones. [More]
UConn Health cancer epidemiologist reveals effect of artificial light on health

UConn Health cancer epidemiologist reveals effect of artificial light on health

Modern life, with its preponderance of inadequate exposure to natural light during the day and overexposure to artificial light at night, is not conducive to the body's natural sleep/wake cycle. [More]
RUB biochemists gain new insights into generation, maintenance of circadian rhythms

RUB biochemists gain new insights into generation, maintenance of circadian rhythms

Biochemists at the Ruhr-Universität Bochum have gained new insights into the generation and maintenance of circadian rhythms. They demonstrated that the Ras protein is important for setting the phase of such a circadian clock, as its activity determines the period length of the rhythm. [More]

If you're looking to improve your heart health by changing your diet, when you eat may be just as important as what you eat. [More]
Naturally occurring melatonin may help us fall asleep

Naturally occurring melatonin may help us fall asleep

If you walk into your local drug store and ask for a supplement to help you sleep, you might be directed to a bottle labeled "melatonin." The hormone supplement's use as a sleep aid is supported by anecdotal evidence and even some reputable research studies. [More]
Vanderbilt researchers find link between the biological clock and Angelman syndrome

Vanderbilt researchers find link between the biological clock and Angelman syndrome

Monitoring participants' biological clocks may be the quickest way to determine the effectiveness of experimental drugs currently under development to treat Angelman syndrome: a debilitating genetic disorder that occurs in more than one in every 15,000 live births. [More]
Intriguing small molecule directs activity of key ‘clock proteins’

Intriguing small molecule directs activity of key ‘clock proteins’

In research published in Nature Communications, Thomas Burris, Ph.D., chair of pharmacological and physiological science at Saint Louis University, reports intriguing findings about a small molecule that directs the activity of key "clock proteins," offering the potential to manage circadian rhythm and treat problems that are associated with its dysfunction, like sleep and anxiety disorders.

Alcohol consumption interferes with sleep homeostasis

Alcohol consumption interferes with sleep homeostasis

Researchers from the University of Missouri School of Medicine have found that drinking alcohol to fall asleep interferes with sleep homeostasis, the body's sleep-regulating mechanism. [More]

Protein that regulates the body's sleep cycle may offer cancer protection

People who work around the clock could actually be setting themselves back, according to Virginia Tech biologists. [More]
Researchers take major step in fight against sleeping sickness

Researchers take major step in fight against sleeping sickness

Researchers from Aarhus University have taken an important step in the fight against sleeping sickness, a disease that is a major problem in parts of Africa. According to the World Health Organization, the disease threatens approximately 60 million people and the treatment options are poor. [More]

Nonlinear correlation between axitinib dose, dBP increase

A pharmacokinetic–pharmacodynamic model shows that diastolic blood pressure rises with increasing doses of axitinib in patients with metastatic renal cell carcinoma, US researchers report, although this relationship is not linear. [More]
SCN clock isn't necessary to align body rhythms with light-dark cycle, study reveals

SCN clock isn't necessary to align body rhythms with light-dark cycle, study reveals

Circadian clocks regulate functions ranging from alertness and reaction time to body temperature and blood pressure. New research published in the November 2014 issue of The FASEB Journal further adds to our understanding of the circadian rhythm by suggesting that the suprachiasmaticus nucleus (SCN) clock, a tiny region of the hypothalamus considered to be the body's "master" timekeeper, is not necessary to align body rhythms with the light-dark cycle.
