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.
In a recent study, scientists at the Department of Cardiology at the University Medical Center of Johannes Gutenberg University Mainz have identified an enzyme responsible for aircraft-related vascular damage.
A team of researchers at VIB and KU Leuven has uncovered why people with a hereditary form of Parkinson's disease suffer from sleep disturbances.
According to a new study, people who routinely had a disrupted night’s sleep had an altered 24 hour cycle were more at risk of getting mood disorders, depression, bipolar disease. They score low on happiness and feel more lonely say researchers. This study, explain researchers, is vital in understanding the balance between rest and activity. The study appeared in the latest issue of the journal Lancet Psychiatry.
A new pilot study conducted by UAB Department of Nutrition Sciences Assistant Professor Courtney Peterson, Ph.D., shows that eating early in the daytime and fasting for the rest of the day improves blood sugar control, blood pressure and oxidative stress, even when people don't change what they eat.
For years, doctors have associated the BRCA1 and BRCA2 gene mutations with an increased risk of breast cancer.
Each year around many people worldwide are diagnosed with a form of dementia. Alzheimer's disease is one of them. The disease manifests itself in memory difficulties in particular, but can also result in personality changes and mood swings.
A new study has highlighted how body clock processes within the body are influenced by night-time light.
Researchers at University of California San Diego School of Medicine are preparing a first-of-its-kind, multidisciplinary investigation to determine if and how cannabidiol, a non-psychoactive compound found in the cannabis plant, provides therapeutic benefit to children with severe symptoms of autism spectrum disorder.
A University of Delaware researcher investigated the relationship between midday-napping behaviors and neurocognitive function in early adolescents and found some keys to helping the teens battle fatigue.
A study performed by an international team led by the Barcelona Institute for Global Health (ISGlobal), a center supported by the "la Caixa" Foundation, reports a link between exposure to blue light at night and higher risk of developing breast and prostate cancer.
Acute myeloid leukemia is a cancer of the blood and bone marrow that comprises 1% of all new cancer cases and almost 2% of cancer deaths in the U.S. The five-year survival rate for the disease is less than 20%.
New research shows that people who habitually stay up late and wake up late are at risk of shorter lives compared to those who follow the old adage – “early to bed and early to rise…” The study titled, “Associations between chronotype, morbidity and mortality in the UK Biobank cohort,” was published in the latest issue of the journal Chronobiology International.
It may be time to tailor students' class schedules to their natural biological rhythms, according to a new study from UC Berkeley and Northeastern Illinois University.
New research published in The Journal of Physiology shows that our brain clock can be shifted by light exposure, potentially to align it with night shift patterns.
EPFL biologists and geneticists have uncovered how the circadian clock orchestrates the 24-hour cycle of gene expression by regulating the structure of chromatin, the tightly wound DNA-protein complex of the cell. The work is published in Genes & Development.
New research has identified the way age impairs the ability of the circadian clock in mammals to re-set itself when exposed to light, resulting in disruption to sleeping patterns and consequent threats to wellbeing
A team of researchers has developed a wearable, non-invasive system to monitor electrical activity in the stomach over 24 hours--essentially an electrocardiogram but for the gastro-intestinal (GI) tract.
Using e-cigarettes may lead to an accumulation of fat in the liver, a study of mice exposed to the devices suggests.
Cellular energy metabolism also follows the rhythm of the circadian clock. A University of Basel study has now shown exactly how this works by revealing the relationship between the circadian rhythm and the mitochondrial network for the first time.
What do bad sleep habits and stiff blood vessels have in common? Nothing good, say scientists exploring what appears to be a direct connection between a circadian clock that isn't working as it should and an enzyme that promotes inflammation working overtime.
