A circadian rhythm is any biological process that displays an endogenous, entrainable oscillation of about 24 hours. These rhythms are driven by a circadian clock, and rhythms have been widely observed in plants, animals, fungi and cyanobacteria. The term circadian comes from the Latin circa, mea...
Disruption of 24-h rhythms leads to cardiovascular disease, including heart failure, myocardial infarction and arrhythmias. 24-h rhythms are present in the development, risk factors, incidence and outcome of cardiovascular disease. Cardiovascular disease leads to disrupted circadian rhythm and sleep proble...
cir·ca·di·an rhythm (sər-kā′dē-ən) A daily cycle of biological activity based on a 24-hour period and influenced by regular variations in the environment, such as the alternation of night and day. Did You Know?Why do you sometimes wake up on time even if your alarm clock...
This master clock responds to light cues received through your eyes, signaling the rhythm for your biological processes.[4] As the sun rises and your body senses the morning daylight, it stimulates cortisol production to give you the energy to meet the day. And as daylight falls and evening ...

The electrochemical potential gradient of K+over the plasma membrane is one of the principal determinants of resting membrane potential in mammalian cells, and we thus deemed it likely that rhythmic regulation of K+transport underlies the rhythm in RBC electrophysiology observed using DEP and FACS. ...

Circadian rhythm Circadian rhythm is an internal biological clock, which enables to sustain an approximately 24-hour rhythm in the absence of environmental cues. In mammals, the circadian clock mechanism consists of cell-autonomous transcription-translation feedback loops that drive rhythmic, 24-hour ex...
