The Circadian Clock, Genes, and Systems Biology

The circadian clock is essential in many organisms. The circadian timing system enables the physiological and behavioral adaptation to the external geophysical changes through the regulation of the temporal cellular processes (Lehmann et al., 2015). In mammals, the master pacemaker … Continue reading

Chronobiology, Chronotherapy, and Rheumatoid Arthritis

Chronobiology studies biological cycles or rhythms. Circadian rhythms are critical for the maintenance of cellular and psychophysiological health. Many health problems are affected by the time of day. For example, the symptoms of rheumatoid arthritis (RA) including joint pain and … Continue reading

Circadian Rhythms and Stem Cell Chronobiology

Circadian rhythms are biological temporal patterns that oscillate in a 24-hour time cycle. Many physiological processes and behavioral variations are controlled by the rhythms, such as the daily sleep-waking cycle. The secretions of hormones and cytokines such as melatonin and … Continue reading

Glucocorticoids, Shift Work, and the Central and Peripheral Clocks

The circadian system can be influenced by both the environment and human activities. For example, shift work can cause a de-synchronization between the circadian timing system in the human body and the external environment (Cuesta et al, 2014). Such disruption … Continue reading

The Effects of Artificial Morning Light on Cognition

Chronic sleep restriction (SR) has detrimental influences on cognitive functions. Although such effects can be reduced by light exposure, it is necessary to find out if naturalistic light conditions such as dawn simulating light can promote daytime cognitive functions continuously … Continue reading
