Environmental Circadian Disruption Elevates the IL-6 Response to Lipopolysaccharide in Blood [PDF]
, 2013 The immune system is regulated by circadian clocks within the brain and immune cells. Environmental circadian disruption (ECD), consisting of a 6-h phase advance of the light:dark cycle once a week for 4 weeks, elevates the inflammatory response to ...

Understanding the role of chromatin remodeling in the regulation of circadian transcription in Drosophila. [PDF]
, 2015 Circadian clocks enable organisms to anticipate daily changes in the environment and coordinate temporal rhythms in physiology and behavior with the 24-h day-night cycle. The robust cycling of circadian gene expression is critical for proper timekeeping,

Making Memories: Why Time Matters [PDF]
, 2018 In the last decade advances in human neuroscience have identified the critical importance of time in creating long-term memories. Circadian neuroscience has established biological time functions via cellular clocks regulated by photosensitive retinal ...

Human circadian variations [PDF]
Journal of Clinical Investigation, 2021 Circadian rhythms, present in most phyla across life, are biological oscillations occurring on a daily cycle. Since the discovery of their molecular foundations in model organisms, many inputs that modify this tightly controlled system in humans have been identified.

Circadian rhythms and hormonal homeostasis: Pathophysiological implications [PDF]
, 2017 Over recent years, a deeper comprehension of the molecular mechanisms that control biological clocks and circadian rhythms has been achieved. In fact, many studies have contributed to unravelling the importance of the molecular clock for the regulation ...

Circadian Rhythm Dysregulation and Restoration: The Role of Melatonin
Nutrients, 2021 Sleep is an essential component of overall human health but is so tightly regulated that when disrupted can cause or worsen certain ailments. An important part of this process is the presence of the well-known hormone, melatonin. This compound assists in

Extraordinary behavioral entrainment following circadian rhythm bifurcation in mice. [PDF]
, 2016 The mammalian circadian timing system uses light to synchronize endogenously generated rhythms with the environmental day. Entrainment to schedules that deviate significantly from 24 h (T24) has been viewed as unlikely because the circadian pacemaker ...

Solving the mystery of human sleep schedules one mutation at a time. [PDF]
, 2013 Sleep behavior remains one of the most enigmatic areas of life. The unanswered questions range from "why do we sleep?" to "how we can improve sleep in today's society?" Identification of mutations responsible for altered circadian regulation of human ...

Mutation of Arabidopsis SPLICEOSOMAL TIMEKEEPER LOCUS1 Causes Circadian Clock Defects [PDF]
, 2012 The circadian clock plays a crucial role in coordinating plant metabolic and physiological functions with predictable environmental variables, such as dusk and dawn, while also modulating responses to biotic and abiotic challenges.
