Circadian Rhythms in Cyanobacteria [PDF]

open access: yesMicrobiology and Molecular Biology Reviews, 2015
SUMMARY Life on earth is subject to daily and predictable fluctuations in light intensity, temperature, and humidity created by rotation of the earth. Circadian rhythms, generated by a circadian clock, control temporal programs of cellular physiology to facilitate adaptation to daily environmental changes.

Circadian rhythms and cancers: the intrinsic links and therapeutic potentials

open access: yesJournal of Hematology & Oncology, 2022
The circadian rhythm is an evolutionarily conserved time-keeping system that comprises a wide variety of processes including sleep–wake cycles, eating–fasting cycles, and activity–rest cycles, coordinating the behavior and physiology of all organs for ...

Circadian rhythms in RA [PDF]

open access: yesAnnals of the Rheumatic Diseases, 2003
Possible roles of cortisol and melatonin It is well known that some clinical signs and symptoms of rheumatoid arthritis (RA) vary within a day and between days, and the morning stiffness seen in patients with RA has become one of the diagnostic criteria of the disease (fig 1).1 Figure 1 Clinical signs and symptoms of articular inflammation in ...
