Altered expression of circadian clock gene, mPer1, in mouse brain and kidney under morphine dependence and withdrawal [PDF]

, 2006
Every physiological function in the human body exhibits some form of circadian rhythmicity. Under pathological conditions, however, circadian rhythmicity may be dusrupted.

Molecular bases of circadian magnesium rhythms across eukaryotes

FEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Circadian Rhythm Sleep Disorder Among Nurses in Emergency Department: a Systematic Review [PDF]

, 2018
Background: Circadian Rhythm Sleep Disorders (CRSD) is a sleep pattern disorder that can be caused by a shift work system, especially the night shift. This disorder can cause various cardiovascular diseases, psychological, decreased concentration, even ...

Use of Actigraphy for the Evaluation of Sleep Disorders and Circadian Rhythm Sleep-Wake Disorders: An American Academy of Sleep Medicine Systematic Review, Meta-Analysis, and GRADE Assessment

Journal of Clinical Sleep Medicine (JCSM), 2018
The purpose of this systematic review is to provide supporting evidence for a clinical practice guideline on the use of actigraphy. The American Academy of Sleep Medicine commissioned a task force of experts in sleep medicine.

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

FEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

An intricate relationship between circadian rhythm dysfunction and psychiatric diseases

Exploration of Neuroscience
There is a complex relationship between circadian rhythm dysfunctions and various psychiatric disorders. Circadian (~24 h) rhythms indicate the rhythmic change of different physiological activities in relation to the environmental light-dark cycle. Shift

Circadian Rhythm Disturbances in Mood Disorders: Insights into the Role of the Suprachiasmatic Nucleus

Journal of Neural Transplantation and Plasticity, 2017
Circadian rhythm disturbances are a common symptom among individuals with mood disorders. The suprachiasmatic nucleus (SCN), in the ventral part of the anterior hypothalamus, orchestrates physiological and behavioral circadian rhythms.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Psychological adaptation to extreme environments: Antarctica as a space analogue [PDF]

, 2018
Space analogues are settings where particular conditions can be reproduced to study physiological and psychological variables experienced in space. Antarctica is one of the most reliable analogues to assess the effects of isolation, confinement, light ...
