Objective Circadian rhythm disruption (CRD) has been associated with inflammation and immune disorders, but its role in SLE progression is unclear. We aimed to investigate the impact of circadian ...

The appearance of these circadian rhythms was associated with sleep maturation. Time of peak variability did not depend on age. Circadian variation was normal in patients with diabetes mellitus.

This meticulous choreography would not be achievable without a circadian clock — just as the flowering plant needs its biological rhythm to take full advantage of the bees’ services. For you and me, ...
