Xuguang Luo, Xinhua Yang, Yanping Yang, Hairong Li, Huilin Cui & Ximei Cao (2020) The interrelationship between inflammatory cytokines and skeletal muscle decay from the viewpoint of circadian rhythms, Archives of Physiology and Biochemistry, DOI: 10.1080/13813455.2020.1782435 Abstract Circadian rhythms affect a variety of physiological processes. Disruption of circadian rhythms causes many diseases, most of which are associated with inflammation. Disruption...

Article https://doi.org/10.1038/s41467-020-15384-9 The cyanobacterium Synechococcus elongatus is a model organism for the study of circadian rhythms. It is naturally competent for transformation—that is, it takes up DNA from the environment, but the underlying mechanisms are unclear. Here, we use a genome-wide screen to identify genes required for natural transformation in S. elongatus, including genes encoding...

Int. J. Environ. Res. Public Health 2020, 17(2), 562; https://doi.org/10.3390/ijerph17020562 Abstract Work-related stress can induce a break in homeostasis by placing demands on the body that are met by the activation of two different systems, the hypothalamic–pituitary–adrenal axis and the sympathetic nervous system. Night-shift work alters the body’s exposure to the natural light–dark schedule and disrupts circadian (daily)...

Front Neuroendocrinol. 2019 Dec 18:100819. doi: 10.1016/j.yfrne.2019.100819. [Epub ahead of print] Abstract Stress, primarily processed via the hypothalamic-pituitary-adrenal (HPA) axis, engages biological pathways throughout the brain and body which promote adaptation and survival to changing environmental demands. Adaptation to environmental challenges is compromised when these pathways are no longer functioning optimally. The physiological and behavioral mechanisms...

Horm Behav. 2019 Apr;110:77-89. doi: 10.1016/j.yhbeh.2019.02.018. Epub 2019 Mar 15. Abstract Circadian time-keeping mechanisms preserve homeostasis by synchronizing internal physiology with predictable variations in the environment and temporally organize the activation of physiological signaling mechanisms to promote survival and optimize the allocation of energetic resources. In this paper, we highlight the importance of the robust circadian...

https://doi.org/10.1016/j.celrep.2019.07.020 Graphical Abstract: Extract: Applying light therapy before high-risk non-cardiac or cardiac surgery to enhance the circadian amplitude might be able to provide robust cardioprotection. Light-elicited circadian amplitude enhancement suggests an overall increase in PER2 levels and concomitant cardioprotection even at the trough of the amplitude, indicating that this strategy could promote general cardioprotection and...
