Research on The Interaction of Exercise-mediated Cardiac Metabolism and Circadian Rhythm

open access: yesShengwu huaxue yu shengwu wuli jinzhan
The relationship between exercise and cardiac health has always been a hotspot in the fields of medicine and exercise science. Recently, with the in-depth study of the biological clock, people have gradually realized the close relationship between ...

Photoperiodic plasticity in circadian clock neurons in insects

open access: yesFrontiers in Physiology, 2013
Since Bünning’s observation of circadian rhythms and photoperiodism in the runner bean Phaseolus multiflorus in 1936, many studies have shown that photoperiodism is based on the circadian clock system.

Impact of circadian clock dysfunction on human health

open access: yesExploration of Neuroscience, 2022
All living organisms exhibit circadian rhythms. Humans show circadian rhythm of the different physiological functions such as sleep-wake cycle, core body temperature, feeding behavior, metabolic activity, heart rate variability, hormone secretion, and ...

Circadian Clocks and Metabolism [PDF]

open access: yes, 2013
Circadian clocks maintain periodicity in internal cycles of behavior, physiology, and metabolism, enabling organisms to anticipate the 24-h rotation of the Earth. In mammals, circadian integration of metabolic systems optimizes energy harvesting and utilization across the light/dark cycle.

Circadian Organization in Hemimetabolous Insects [PDF]

open access: yes, 2004
The circadian system of hemimetabolous insects is reviewed in respect to the locus of the circadian clock and multioscillatory organization. Because of relatively easy access to the nervous system, the neuronal organization of the clock system in ...

The contribution of circadian clock to the biological processes

open access: yesFrontiers in Molecular Biosciences
All organisms have various circadian, behavioral, and physiological 24-h periodic rhythms, which are controlled by the circadian clock. The circadian clock controls various behavioral and physiological rhythms.

Heritable gene expression variability and stochasticity govern clonal heterogeneity in circadian period.

open access: yesPLoS Biology, 2020
A ubiquitous feature of the circadian clock across life forms is its organization as a network of cellular oscillators, with individual cellular oscillators within the network often exhibiting considerable heterogeneity in their intrinsic periods.

Entrainment of the Human Circadian Clock [PDF]

open access: yesCold Spring Harbor Symposia on Quantitative Biology, 2007
Humans are an excellent model system for studying entrainment of the circadian clock in the real world. Unlike the situation in laboratory experiments, entrainment under natural conditions is achieved by different external signals as well as by internal signals generated by multiple feedbacks within the system (e.g., behavior-dependent light and ...
