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.

Circadian rhythms, cardiac arrhythmias and sudden death

open access: yesFrontiers in Bioscience-Landmark, 2021
The heart, like most mammalian organs, is influenced by circadian patterns. The suprachiasmatic nucleus in the hypothalamus has a key role in this influence, via various neurohumoral factors, particularly the autonomic nervous system.

Circadian rhythms and the liver

open access: yesLiver International, 2023
AbstractThis narrative review briefly describes the mammalian circadian timing system, the specific features of the liver clock, also by comparison with other peripheral clocks, the role of the liver clock in the preparation of food intake, and its relationship with energy metabolism.

Glucocorticoids Regulate Circadian Rhythm of Innate and Adaptive Immunity

open access: yesFrontiers in Immunology, 2020
Animals have evolved circadian rhythms to adapt to the 24-h day-night cycle. Circadian rhythms are controlled by molecular clocks in the brain and periphery, which is driven by clock genes.

Circadian rhythm disorders in patients with advanced cancer: a scoping review

open access: yesFrontiers in Oncology, 2023
Circadian rhythms can be demonstrated in several biomarkers and behavioural activities, with rhythmical patterns occurring roughly over a 24-h period.

Circadian rest-activity rhythms predict cognitive function in early Parkinson's disease independently of sleep [PDF]

open access: yes, 2018
BACKGROUND: Cognitive impairment is a common and debilitating symptom of Parkinson's disease (PD), and its etiology is likely multifactorial. One candidate mechanism is circadian disruption. Although there is evidence of circadian abnormalities in PD, no

Serotonin and circadian rhythms. [PDF]

open access: yesPsychology & Neuroscience, 2010
All mammal behaviors and functions exhibit synchronization with environmental rhythms. This is accomplished through an internal mechanism that generates and modulates biological rhythms. The circadian timing system, responsible for this process, is formed by connected neural structures.
