Epigenetic Mechanisms in the Transcriptional Regulation of Circadian Rhythm in Mammals

open access: yesBiology
Almost all organisms, from the simplest bacteria to advanced mammals, havea near 24 h circadian rhythm. Circadian rhythms are highly conserved across different life forms and are regulated by circadian genes as well as by related transcription factors ...

Circadian Regulation of Synaptic Plasticity

open access: yesBiology, 2016
Circadian rhythms refer to oscillations in biological processes with a period of approximately 24 h. In addition to the sleep/wake cycle, there are circadian rhythms in metabolism, body temperature, hormone output, organ function and gene expression ...

Circadian Phase-Shifting Effects of Bright Light, Exercise, and Bright Light + Exercise [PDF]

open access: yes, 2016
: Limited research has compared the circadian phase-shifting effects of bright light and exercise and additive effects of these stimuli. The aim of this study was to compare the phase-delaying effects of late night bright light, late night exercise, and ...

Biomaterials for modulating cellular responses of endogenous tendon stem/progenitor cells: A promising avenue for tendon regeneration

open access: yesBMEMat, EarlyView.
This review comprehensively summarizes emerging biomaterial‐based strategies and underlying mechanisms for modulating endogenous tendon stem/progenitor cells (TSPCs). It offers the most recent insights into TSPC physiology and potential applications of tissue engineering and regenerative medicine in tendons.

Circadian Rhythms of the Liver and Their Sexual Dimorphism: Current State of the Problem

open access: yesИнновационная медицина Кубани
The rhythmicity of life functioning processes at the cellular, organ, and system levels is one of the fundamental properties of living things. Among the wide range of biorhythms, circadian rhythms are the most important for mammals. In mammals, circadian

Circadian Rhythm Disruption [PDF]

open access: yesAAOHN Journal, 2011
The circadian rhythm is a 24-hour cycle subject to outside influences. Disruptions of this cycle (e.g., shift work and international travel) have implications for occupational health nurses.

Circadian and Ultradian Rhythms of Free Glucocorticoid Hormone Are Highly Synchronized between the Blood, the Subcutaneous Tissue, and the Brain [PDF]

open access: yes, 2012
Total glucocorticoid hormone levels in plasma of various species, including humans, follow a circadian rhythm that is made up from an underlying series of hormone pulses. In blood most of the glucocorticoid is bound to corticosteroid-binding globulin and

Beyond antimicrobials: Ecological nano‐strategies for rebalancing dysbiotic oral microbial homeostasis

open access: yesBMEMat, EarlyView.
Oral microbial homeostasis, a dynamic host‐microbe balance, is vital in infectious diseases. Conventional antibiotics often disrupt this homeostasis, spurring interest in nanomaterials for oral microbial homeostasis rebalancing. This review outlines nanomaterial strategies across three ecological levels (population/community, ecosystem, and cross ...

Importance of Circadian Rhythms in the Ocular Surface

open access: yesBiomolecules
Circadian rhythms are a ubiquitous feature throughout the organism. Accumulating evidence suggests that the dysfunction of circadian rhythms due to genetic mutations or environmental factors contributes to the genesis and progress of multiple diseases ...

The influence of circadian variables on ecotoxicology metabolomics

open access: yesBiological Reviews, EarlyView.
ABSTRACT Ecotoxicologists are using metabolomics increasingly to gain insight into toxicological mechanisms and sublethal effects of chemical exposures. Metabolomics offers a sensitive multi‐parameter approach that can detect biochemical responses not obvious using apical and behavioural endpoints.
