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.

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 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.

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.

Research progress on relationships of circadian rhythm with thyroid function and diseases

open access: yes环境与职业医学, 2022
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.

Modulatory effects in circadian-related diseases via the reciprocity of tea polyphenols and intestinal microbiota

open access: yesFood Science and Human Wellness, 2022
Tea is a widespread functional plant resource. Phytochemicals such as tea polyphenols (TP) can interact with the intestinal flora and participate in regulating the expression and rhythm of biological clock genes.

Cosinor-rhythmometry for 24-h urinary sodium, potassium, creatinine excretion in the Chinese adult population

open access: yesChinese Medical Journal, 2021
. Background:. The low accuracy of equations predicting 24-h urinary sodium excretion using a single spot urine sample contributed to the misclassification of individual sodium intake levels.

Circadian rhythms and diabetes [PDF]

open access: yesJournal of Diabetes Investigation, 2011
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.
