REM Sleep: An Unknown Indicator of Sleep Quality.
Barbato G. Barbato G. Int J Environ Res Public Health. 2021 Dec 9;18(24):12976. doi: 10.3390/ijerph182412976. Int J Environ Res Public Health. 2021. PMID: 34948586 Free PMC article. Review.
The correct phase relationship of the sleep period with the circadian pacemaker is an important factor to guarantee adequate restorative sleep duration and sleep continuity, thus providing the necessary background for a good night's sleep. ...An adequate amount of REM slee …

Rhythms in cognition: The evidence revisited.
Keitel C, Ruzzoli M, Dugué L, Busch NA, Benwell CSY. Keitel C, et al. Eur J Neurosci. 2022 Jun;55(11-12):2991-3009. doi: 10.1111/ejn.15740. Eur J Neurosci. 2022. PMID: 35696729 Free PMC article. No abstract available.
Metabolic and chemical architecture of the mammalian circadian clock.
Laothamatas I, Rasmussen ES, Green CB, Takahashi JS. Laothamatas I, et al. Cell Chem Biol. 2023 Sep 21;30(9):1033-1052. doi: 10.1016/j.chembiol.2023.08.014. Epub 2023 Sep 13. Cell Chem Biol. 2023. PMID: 37708890 Review.
Circadian rhythms are endogenous periodic biological processes that occur on a daily timescale. These rhythms are generated by a transcriptional/translational feedback loop that consists of the CLOCK-BMAL1 heterodimeric transcriptional activator complex and the PER1/2-CRY1 …

Circadian rhythms.
Aréchiga H. Aréchiga H. Curr Opin Neurobiol. 1993 Dec;3(6):1005-10. doi: 10.1016/0959-4388(93)90174-w. Curr Opin Neurobiol. 1993. PMID: 8124069 Review.
New information was produced on the gene control of circadian rhythm generation in Drosophila, as well as interesting advances in the understanding of neuronal mechanisms involved in the generation, entrainment and coupling of circadian rhythms in various species....

Control of circadian rhythm on cortical excitability and synaptic plasticity.
Lodovichi C, Ratto GM. Lodovichi C, et al. Front Neural Circuits. 2023 Mar 30;17:1099598. doi: 10.3389/fncir.2023.1099598. eCollection 2023. Front Neural Circuits. 2023. PMID: 37063387 Free PMC article. Review.
Living organisms navigate through a cyclic world: activity, feeding, social interactions are all organized along the periodic succession of night and day. At the cellular level, periodic activity is controlled by the molecular machinery driving the circadian regulat …

Periodic Parasites and Daily Host Rhythms.
Prior KF, Rijo-Ferreira F, Assis PA, Hirako IC, Weaver DR, Gazzinelli RT, Reece SE. Prior KF, et al. Cell Host Microbe. 2020 Feb 12;27(2):176-187. doi: 10.1016/j.chom.2020.01.005. Cell Host Microbe. 2020. PMID: 32053788 Free PMC article. Review.
In contrast, the regulatory mechanisms and fitness consequences of biological rhythms exhibited by parasites remain mysterious. Here, we explore how periodicity in parasite traits is generated and why daily rhythms matter for parasite fitness. ...

Coupling-dependent metabolic ultradian rhythms in confluent cells.
Yang S, Yamazaki S, Cox KH, Huang YL, Miller EW, Takahashi JS. Yang S, et al. Proc Natl Acad Sci U S A. 2022 Nov 8;119(45):e2211142119. doi: 10.1073/pnas.2211142119. Epub 2022 Nov 2. Proc Natl Acad Sci U S A. 2022. PMID: 36322771 Free PMC article.
Here, we report the discovery of temperature-sensitive ultradian rhythms in mammalian fibroblasts that are independent of both the cell cycle and the circadian clock. The period in each culture is stable over time but varies in different cultures (ranging from 3 to 24 h). …

Determining ICU EEG periodic patterns and why it matters.
Gélisse P, Tatum WO, Crespel A, Jallon P, Kaplan PW. Gélisse P, et al. J Neurol. 2023 Oct;270(10):4744-4752. doi: 10.1007/s00415-023-11835-7. Epub 2023 Jul 1. J Neurol. 2023. PMID: 37393201 Free PMC article. Review.
Historically, periodic EEG patterns were described as any pattern with stereotyped paroxysmal complexes occurring at regular intervals, i.e., the period (T). ...More important than the inter-discharge interval (t2), periodic EEG patterns occur at time regular …

Does day length matter for nutrient responsiveness?
Siqueira JA, Zsögön A, Fernie AR, Nunes-Nesi A, Araújo WL. Siqueira JA, et al. Trends Plant Sci. 2023 Oct;28(10):1113-1123. doi: 10.1016/j.tplants.2023.04.012. Epub 2023 Jun 1. Trends Plant Sci. 2023. PMID: 37268488 Review.
For over 2500 years, considerable agronomic interest has been paid to soil fertility. Both crop domestication and the Green Revolution shifted photoperiodism and the circadian clock in cultivated species, although this contributed to an increase in the demand for chemical …
