Circadian rhythms in thrombosis and atherothrombotic events [PDF]

Frontiers in Bioscience-Landmark, 2022
Biological circadian rhythms in living organisms are regulated by molecular clocks. Several of these clocks are present in blood vessels, peripheral tissues, and immune cells.

Keeping an eye on circadian time in clinical research and medicine

Clinical and Translational Medicine, 2022
Background Daily rhythms are observed in humans and almost all other organisms. Most of these observed rhythms reflect both underlying endogenous circadian rhythms and evoked responses from behaviours such as sleep/wake, eating/fasting, rest/activity ...

S20098 Affects the Free-Running Rhythms of Body Temperature and Activity and Decreases Light-Induced Phase Delays of Circadian Rhythms of the Rat [PDF]

, 2001
Mammalian endogenous circadian rhythms are entrained to the environmental day-night cycle by light exposure. Melatonin is involved in this entrainment by signaling the day-night information to the endogenous circadian pacemaker. Furthermore, melatonin is

Cardiomyocyte Circadian Oscillations Are Cell-Autonomous, Amplified by β-Adrenergic Signaling, and Synchronized in Cardiac Ventricle Tissue. [PDF]

PLoS ONE, 2016
Circadian clocks impact vital cardiac parameters such as blood pressure and heart rate, and adverse cardiac events such as myocardial infarction and sudden cardiac death. In mammals, the central circadian pacemaker, located in the suprachiasmatic nucleus

Aging and circadian rhythms [PDF]

Current Opinion in Insect Science, 2015
Circadian clocks are cell-autonomous molecular feedback loops that generate daily rhythms in gene expression, cellular functions, physiological processes and behavior. The mechanisms of circadian clocks are well understood in young fruit flies Drosophila melanogaster, but less is known about how circadian system changes during organismal aging. Similar

Evening chronotypes experience poor sleep quality when taking classes with early starting times

Sleep Science, 2010
Background and objective: The sleep-wake cycles of medical students are affected by their academic demands and class starting times. Despite their different sleep needs and characteristics (such as chronotype), all students must follow ...

An adipokine feedback regulating diurnal food intake rhythms in mice

eLife, 2020
Endogenous circadian clocks have evolved to anticipate 24 hr rhythms in environmental demands. Recent studies suggest that circadian rhythm disruption is a major risk factor for the development of metabolic disorders in humans. Conversely, alterations in

Oxyntomodulin regulates resetting of the liver circadian clock by food

eLife, 2015
Circadian clocks coordinate 24-hr rhythms of behavior and physiology. In mammals, a master clock residing in the suprachiasmatic nucleus (SCN) is reset by the light–dark cycle, while timed food intake is a potent synchronizer of peripheral clocks such as

Circadian Rhythms of Locomotor Activity Mediated by Cryptochrome 2 and Period 1 Genes in the Termites Reticulitermes chinensis and Odontotermes formosanus

Insects, 2023
Locomotor activity rhythms are crucial for foraging, mating and predator avoidance in insects. Although the circadian rhythms of activity have been studied in several termite species, the molecular mechanisms of circadian rhythms in termites are still ...

The TIME FOR COFFEE gene maintains the amplitude and timing of Arabidopsis circadian clocks [PDF]

, 2003
Plants synchronize developmental and metabolic processes with the earth's 24-h rotation through the integration of circadian rhythms and responses to light.
