Endogenous circadian timekeepers are found in most cells and organs of the body, including the different types of adipose tissues. This clock network orchestrates 24-hour rhythms of physiology and behavior to adapt the organism to daily recurring changes in the environment. Energy intake and ...
Additionally, the onset of acute myocardial infarction, stroke, arrhythmias and other adverse cardiovascular events show circadian rhythmicity. In this Review, we summarize the role of the circadian clock in all major cardiovascular cell types and organs. Second, we discuss the role of circadian ...
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...

Thecircadian rhythmis regulated by an intrinsic time-tracking system, composed both of a central and a peripheral clock, which influences the cycles of activities and sleep of an individual over 24 h. At the molecular level, the circadian rhythm begins when two basic helix-loop-helix/Per-ARNT...

In mammals, the circadian system is an integral regulatory system composed of a master clock and peripheral clocks. The master clock exists in the suprachiasmatic nucleus (SCN) of the brain, whereas the peripheral clocks reside in peripheral tissues and organs, including the liver, skin, lungs, ...

Cell birth and survival in the adult hippocampus is regulated by a circadian clock, so disrupting it can disrupt the process of neurogenesis. Their findings support the hypothesis that it is this internal misalignment, this state of desynchrony between and within organs, th...
The peripheral clock can be periodically synchronized to geophysical time mainly via the photoperiod of sunrise and sunset.12Other known inputs to the peripheral clock include feeding and exercise,13,14,15with studies having demonstrated that physical activity can modulate the rhythm of the clock mac...
