Circadian Rhythm News and Research

RSS

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.

Daytime eating maintains circadian alignment, prevents glucose intolerance despite mistimed sleep

What are the effects of eating during the nighttime instead of the daytime? New research, focused on a simulation of night shift work, may hold implications for people eating at atypical times -; like those experiencing jet lag, circadian rhythm sleep disorders, or who tend to sleep late during the weekends.

Mitochondria of diabetic patients can't keep track of time, study finds

Almost all cells regulate their biological processes over a 24-hour period, otherwise called a cell's circadian rhythm. To do so, cells use a biological clock that cycles different genes on and off throughout the day and night.

Scientists reveal the importance of circadian rhythm on the immune system

Circadian clocks, which regulate most of the physiological processes of living beings over a rhythm of about 24 hours, are one of the most fundamental biological mechanisms.

Researchers reconstitute the biological clock to better understand circadian rhythms

Daily cycles in virtually every aspect of our physiology are driven by biological clocks (also called circadian clocks) in our cells.

Study offers important insights into how circadian clocks function at the subcellular level

Almost every living thing on Earth-;from bacteria to plants to people-;have a circadian rhythm, the biological clock that controls both physiology and behavior of organisms over a 24-hour period.

Intermittent fasting slows aging and increases longevity in fruit flies, study shows

Whether intermittent fasting is called the 5:2 diet or the 16/8 method, celebrities swear that these eating regimens are a great way to lose weight. Fasting is now trendy, but real science backs up claims that fasting two days a week or restricting eating to an eight-hour window each day leads to weight loss.

High concentrations of blood sodium can influence the biological clock of mice

A new study from McGill University shows that increases in the concentrations of blood sodium can have an influence on the biological clock of mice, opening new research avenues for potentially treating the negative effects associated with long-distance travel or shift work.

Disrupted circadian rhythms in older adults linked to increased risk of Parkinson's disease

Older men who have a weak or irregular circadian rhythm guiding their daily cycles of rest and activity are more likely to later develop Parkinson's disease, according to a new study by scientists at the UC San Francisco Weill Institute for Neurosciences who analyzed 11 years of data for nearly 3,000 independently living older men.
