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.
Due to the fact that REM sleep is controlled by the circadian clock, it can provide a window-like mechanism that defines the termination of the sleep period when there is still the necessity to complete the sleep process (not only wake-related homeostasis) and to me …

Timing in the Testis.
Bittman EL. Bittman EL. J Biol Rhythms. 2016 Feb;31(1):12-36. doi: 10.1177/0748730415618297. Epub 2015 Dec 8. J Biol Rhythms. 2016. PMID: 26656623 Review.
Recent evidence indicates that oscillations of retinoic acid play a major role in determining periodicity of the seminiferous epithelium. In the interstitial space, Leydig cells produce the steroid hormones required both for the completion of spermatogenesis and the …

Rhythms of behavior: are the times changin'?
Häfker NS, Tessmar-Raible K. Häfker NS, et al. Curr Opin Neurobiol. 2020 Feb;60:55-66. doi: 10.1016/j.conb.2019.10.005. Epub 2019 Dec 5. Curr Opin Neurobiol. 2020. PMID: 31812940 Review.
We further address diel, seasonal and potential lunar rhythms of humans. While we cannot be complete, we aim to emphasize three aspects: First, to raise awareness for the all-encompassing presence of behavioral rhythms and their importance in ecology and evolution. ...

Review: Circadian clocks and rhythms in the vascular tree.
Han Q, Bagi Z, Rudic RD. Han Q, et al. Curr Opin Pharmacol. 2021 Aug;59:52-60. doi: 10.1016/j.coph.2021.04.010. Epub 2021 Jun 7. Curr Opin Pharmacol. 2021. PMID: 34111736 Free PMC article. Review.
New research continues to tackle how circadian clocks act in the vasculature, describing influences in experimental and human disease, identifying potential target genes, compensatory molecules, that ultimately reveal a complexity that is vascular-bed-specific, cell-type-specific …

Periodisation and the prevention of overtraining.
Fry RW, Morton AR, Keast D. Fry RW, et al. Can J Sport Sci. 1992 Sep;17(3):241-8. Can J Sport Sci. 1992. PMID: 1325265 Review.
Training in cycles provides guidelines for the times in the training programme when regeneration should be complete, and therefore the times when the athlete can be screened for overtraining without confusing the fatigue of overload training with that of overtraining. ...

Cyclical migraine.
Medina JL, Diamond S. Medina JL, et al. Arch Neurol. 1981 Jun;38(6):343-4. doi: 10.1001/archneur.1981.00510060045005. Arch Neurol. 1981. PMID: 6786269
We have observed 27 migraineurs whose headaches occurred in groups separated by headache-free periods. Twenty-one of the patients were women. The headaches occurred on either side in most patients. ...In many patients, the cycles were often accompanied by a constant, low-g …

Smelling Time: A Neural Basis for Olfactory Scene Analysis.
Ache BW, Hein AM, Bobkov YV, Principe JC. Ache BW, et al. Trends Neurosci. 2016 Oct;39(10):649-655. doi: 10.1016/j.tins.2016.08.002. Trends Neurosci. 2016. PMID: 27594700 Free PMC article. Review.
We postulate that bORNs represent an unsuspected neural mechanism through which time can be accurately measured, and that 'smelling time' completes the requirements for true olfactory scene analysis....

[Regulation of ILC3/Th17-Mediated Intestinal Immune Response by Circadian Rhythm].
Chang JL, Qiu J. Chang JL, et al. Sichuan Da Xue Xue Bao Yi Xue Ban. 2022 Jan;53(1):15-19. doi: 10.12182/20220160502. Sichuan Da Xue Xue Bao Yi Xue Ban. 2022. PMID: 35048594 Free PMC article. Review. Chinese.
The circadian rhythm is a widely-recognized phenomenon, according to which the life activities of organisms change periodically, synchronizing with the day and night cycles. The activities of the immune system are also regulated by the circadian rhythm. Group 3 innate lymp …

Mystery of rhythmic signal emergence within the suprachiasmatic nuclei.
Sumová A, Čečmanová V. Sumová A, et al. Eur J Neurosci. 2020 Jan;51(1):300-309. doi: 10.1111/ejn.14141. Epub 2018 Sep 27. Eur J Neurosci. 2020. PMID: 30188597 Review.
In mammals, the circadian clock in the suprachiasmatic nuclei (SCN) develops during the perinatal period. The rhythmicity first appears at the level of individual SCN neurons during the fetal stage, and this step is often misinterpreted as the time of complete SCN c …

Effect of adenotonsillectomy in PFAPA syndrome.
Licameli G, Jeffrey J, Luz J, Jones D, Kenna M. Licameli G, et al. Arch Otolaryngol Head Neck Surg. 2008 Feb;134(2):136-40. doi: 10.1001/archoto.2007.7. Arch Otolaryngol Head Neck Surg. 2008. PMID: 18283154 Review.
OBJECTIVE: To assess the benefits of adenotonsillectomy in the treatment of pediatric patients with PFAPA (periodic fever, aphthous ulcers, pharyngitis, and adenitis) syndrome. ...CONCLUSIONS: Our findings showed complete resolution of symptoms in 26 of 27 patients …
