Circadian rhythm perturbation causes IBS-like characteristics and altered fecal metabolome in mice [PDF]

open access: yesBMC Microbiology
Background Circadian rhythm disturbance is associated with functional gastrointestinal disorders such as irritable bowel syndrome (IBS). This study aimed to explore the effects of dysregulated circadian rhythm on visceral sensitivity, colonic ...

Therapeutic potential of ginsenosides in circadian rhythm-based skin disorders [PDF]

open access: yesJournal of Ginseng Research
The circadian rhythm, a biological system all living organisms possess, has become increasingly important as sleep patterns become more irregular. Circadian rhythms affect various cell types (fibroblasts, fat cells, muscles, etc.) and organs (the liver ...

Circadian rhythms [PDF]

open access: yesBrain Research Reviews, 1993
Circadian rhythms are a ubiquitous adaptation of eukaryotic organisms to the most reliable and predictable of environmental changes, the daily cycles of light and temperature. Prominent daily rhythms in behavior, physiology, hormone levels and biochemistry (including gene expression) are not merely responses to these environmental cycles, however, but ...

Sleep and circadian rhythm disturbance in kidney stone disease: a narrative review

open access: yesFrontiers in Endocrinology, 2023
The circadian rhythm generated by circadian clock genes functions as an internal timing system. Since the circadian rhythm controls abundant physiological processes, the circadian rhythm evolved in organisms is salient for adaptation to environmental ...

Relationship between circadian rhythm characteristics and chronotypes with multiple sclerosis: literature review

open access: yesNeurologijos seminarai, 2021
Circadian rhythm disorder is described as discrepancy between person’s sleep habits and usual, generally accepted sleep model during 24-hour period. Circadian rhythm disorders affect not only person’s working capacity during the day but also may reduce ...

AMPK regulates circadian rhythms in a tissue- and isoform-specific manner. [PDF]

open access: yesPLoS ONE, 2011
AMP protein kinase (AMPK) plays an important role in food intake and energy metabolism, which are synchronized to the light-dark cycle. In vitro, AMPK affects the circadian rhythm by regulating at least two clock components, CKIα and CRY1, via direct ...

Circadian secretion rhythm of GLP-1 and its influencing factors

open access: yesFrontiers in Endocrinology, 2022
Circadian rhythm is an inherent endogenous biological rhythm in living organisms. However, with the improvement of modern living standards, many factors such as prolonged artificial lighting, sedentarism, short sleep duration, intestinal flora and high ...

Wavelengths and irradiances modulate the circadian rhythm of Neurospora crassa.

open access: yesPLoS ONE, 2022
The circadian rhythm affects the biological evolution and operating mechanisms of organisms. The impact of light on the circadian rhythm is a significant concern for both biology and human well-being.
