Research progress on relationships of circadian rhythm with thyroid function and diseases
Circadian rhythm is a phenomenon of diurnal changes in life activities formed by a transcription-translation feedback loop of biological clock genes affected by external environmental conditions.

Effects of environmental enrichment on behavioral responses to novelty, learning, and memory, and the circadian rhythm in cortisol in growing pigs [PDF]
Previously we showed that pigs reared in an enriched environment had higher baseline salivary cortisol concentrations during the light period than pigs reared under barren conditions.

Environmental Circadian Disruption Elevates the IL-6 Response to Lipopolysaccharide in Blood [PDF]
The immune system is regulated by circadian clocks within the brain and immune cells. Environmental circadian disruption (ECD), consisting of a 6-h phase advance of the light:dark cycle once a week for 4 weeks, elevates the inflammatory response to ...

Arrhythmic perch hopping and rhythmic feeding of starlings in constant light: Separate circadian oscillators? [PDF]
Perch hopping activity and food intake were recorded in starlings in different intensities of continuous illumination (LL), varying from 0.1 to 1000 lux. Circadian rhythmicity in perch hopping disappeared in 10 lux and all higher intensities. In contrast,

Circadian rhythms and diabetes [PDF]
All free‐living organisms are regulated by the 24‐h light and dark cycle produced by Earth’s rotation. In mammals, circadian rhythms are indispensble for the regulation of physiological and biochemical processes in the body. In 1972, the suprachiasmatic nucleus was shown to be required for daily rhythms in animal behavior1.

Rhythms of Locomotion Expressed by Limulus polyphemus, the American Horseshoe Crab: II. Relationship to Circadian Rhythms of Visual Sensitivity [PDF]
In the laboratory, horseshoe crabs express a circadian rhythm of visual sensitivity as well as daily and circatidal rhythms of locomotion. The major goal of this investigation was to determine whether the circadian clock underlying changes in visual ...

Mechanism of robust circadian oscillation of KaiC phosphorylation in vitro [PDF]
By incubating the mixture of three cyanobacterial proteins, KaiA, KaiB, and KaiC, with ATP in vitro, Kondo and his colleagues reconstituted the robust circadian rhythm of the phosphorylation level of KaiC (Science, 308; 414-415 (2005)).
