ELF4 is required for oscillatory properties of the circadian clock [PDF]

, 2007
Circadian clocks are required to coordinate metabolism and physiology with daily changes in the environment. Such clocks have several distinctive features, including a free-running rhythm of approximately 24 h and the ability to entrain to both light or ...

Circadian disturbances and frailty risk in older adults

Nature Communications, 2023
Frailty is characterized by diminished resilience to stressor events. It is associated with adverse future health outcomes and impedes healthy aging.

FLOWERING LOCUS C -dependent and -independent regulation of the circadian clock by the autonomous and vernalization pathways [PDF]

, 2006
Background The circadian system drives pervasive biological rhythms in plants. Circadian clocks integrate endogenous timing information with environmental signals, in order to match rhythmic outputs to the local day/night cycle.

The contributions of interlocking loops and extensive nonlinearity to the properties of circadian clock models [PDF]

, 2010
Sensitivity and robustness are essential properties of circadian clock systems, enabling them to respond to the environment but resist noisy variations. These properties should be recapitulated in computational models of the circadian clock.

Circadian Organization in Hemimetabolous Insects [PDF]

, 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 hormonal Zeitgeber melatonin: role as a circadian modulator in memory processing [PDF]

, 2012
The neuroendocrine substance melatonin is a hormone synthesized rhythmically by the pineal gland under the influence of the circadian system and alternating light/dark cycles. Melatonin has been shown to have broad applications, and consequently becoming

Spectroscopic Influence of Virtual Reality and Augmented Reality Display Devices on the Human Nonvisual Characteristics and Melatonin Suppression Response

IEEE Photonics Journal, 2018
It has been elucidated that the responses to light by the human eye influence not only color and brightness recognition but also physiological aspects such as hormones. Melatonin, which affects human circadian rhythms, is sensitive to the blue wavelength

Circadian rhythms

, 2020
Circadian rhythms are endogenous, near 24-hour oscillations that underlie nearly all facets of our health and behavior. The daily cycle of sleep and wake is the most conspicuous circadian-influenced behavior in humans.
