Susceptibility rhythm to bacterial endotoxin in myeloid clock-knockout mice

eLife, 2021
Local circadian clocks are active in most cells of our body. However, their impact on circadian physiology is still under debate. Mortality by endotoxic (LPS) shock is highly time-of-day dependent and local circadian immune function such as the cytokine ...

CHRONOBIOLOGY OF DEPRESSION

Psychiatria Danubina, 2021
Seasonal fluctuations in mood, drive, energy, sleeping- and eating behavior, weight, as well as further important mental and physical functions, and the utilization of light as an effective treatment option were already described by Hippocrates of Kos and Araeteus, the Cappadocian.

Chronobiology by moonlight [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2013
Most studies in chronobiology focus on solar cycles (daily and annual). Moonlight and the lunar cycle received considerably less attention by chronobiologists. An exception are rhythms in intertidal species. Terrestrial ecologists long ago acknowledged the effects of moonlight on predation success, and consequently on predation risk, foraging behaviour

Using chronobiology-based second-generation artificial intelligence digital system for overcoming antimicrobial drug resistance in chronic infections

Annals of Medicine, 2023
Antimicrobial resistance results from the widespread use of antimicrobial agents and is a significant obstacle to the effectiveness of these agents. Numerous methods are used to overcome this problem with moderate success.

Introduction to Chronobiology [PDF]

Cold Spring Harbor Perspectives in Biology, 2017
A diverse range of species, from cyanobacteria to humans, evolved endogenous biological clocks that allow for the anticipation of daily variations in light and temperature. The ability to anticipate regular environmental rhythms promotes optimal performance and survival.

IARC 2019: “Night shift work” is probably carcinogenic: What about disturbed chronobiology in all walks of life?

Journal of Occupational Medicine and Toxicology, 2019
In June of 2019, a working group convened by the International Agency for Research on Cancer [IARC] concluded that “night shift work” is probably carcinogenic to humans (a Group 2A carcinogen).

Insomnia subtypes characterised by objective sleep duration and NREM spectral power and the effect of acute sleep restriction: an exploratory analysis

Scientific Reports, 2021
Insomnia disorder (ID) is a heterogeneous disorder with proposed subtypes based on objective sleep duration. We speculated that insomnia subtyping with additional power spectral analysis and measurement of response to acute sleep restriction may be ...

Short and long sleeping mutants reveal links between sleep and macroautophagy

eLife, 2021
Sleep is a conserved and essential behavior, but its mechanistic and functional underpinnings remain poorly defined. Through unbiased genetic screening in Drosophila, we discovered a novel short-sleep mutant we named argus.

Brain activity during a working memory task after daily caffeine intake and caffeine withdrawal: a randomized double-blind placebo-controlled trial

Scientific Reports, 2023
Acute caffeine intake has been found to increase working memory (WM)-related brain activity in healthy adults without improving behavioral performances.
