Circadian Rhythm
A circadian rhythm (/sərˈkeɪdiən/), or circadian cycle, is a natural, internal process that regulates the sleep–wake cycle and repeats roughly every 24 hours. It can refer to any process that originates within an organism (is endogenous) and responds to the environment (entrained by the environment).

- The research progress and prospects of circadian rhythm in obesity: a bibliometric analysisby Ye Dou on January 22, 2025
CONCLUSION: Our study demonstrates that research on circadian rhythms in obesity has been rapidly expanding, with increasingly in-depth exploration of the topic. It is recommended to strengthen cooperation between countries and institutions to jointly promote research in this field. The gene expression of obesity is an early hotspot in the study of circadian rhythm and obesity, and emerging research areas such as intermittent fasting, restricted feeding, endothelial nitric oxide synthase and gut...

- NTRC mediates the coupling of chloroplast redox rhythm with nuclear circadian clock in plant cellsby Seol Ki Paeng on January 21, 2025
The intricate interplay between cellular circadian rhythms, primarily manifested in the chloroplast redox oscillations-characterized by diel hyperoxidation/reduction cycles of 2-Cys Peroxiredoxins-and the nuclear transcription/translation feedback loop (TTFL) machinery within plant cells, demonstrates a remarkable temporal coherence. However, the molecular mechanisms underlying the integration of these circadian rhythms remain elusive. Here, we elucidate that the chloroplast redox protein,...
- Beyond sleep: Rest and activity rhythm as a marker of preclinical and mild dementia in older adults with less educationby Erika Satomi on January 21, 2025
CONCLUSION: Daytime activity intensity and fragmented rhythm during the day and night may play an important role as markers for cognitive impairment in less educated populations. Future studies with larger samples should confirm these findings.
