Diminished circadian and ultradian rhythms of human brain activity in pathological tissue in vivo [PDF]
arXiv, 2023 Chronobiological rhythms, such as the circadian rhythm, have long been linked to neurological disorders, but it is currently unknown how pathological processes affect the expression of biological rhythms in the brain. Here, we use the unique opportunity of long-term, continuous intracranially recorded EEG from 38 patients (totalling 6338 hours) to ...

Charting the landscape of the environmental exposome
iMeta, Volume 1, Issue 4, December 2022., 2022 We describe the biological and chemical components of the environmental exposomes in three major environmental matrices that are highly relevant to human and social‐economical health—air, soil, and water. We discuss how different exposome components can interact with each other. Finally, we propose a list of outstanding challenges to be tackled to push

Emergence of Adaptive Circadian Rhythms in Deep Reinforcement Learning [PDF]
arXiv, 2023 Adapting to regularities of the environment is critical for biological organisms to anticipate events and plan. A prominent example is the circadian rhythm corresponding to the internalization by organisms of the $24$-hour period of the Earth's rotation.

Aging and circadian rhythms [PDF]
Current Opinion in Insect Science, 2015 Circadian clocks are cell-autonomous molecular feedback loops that generate daily rhythms in gene expression, cellular functions, physiological processes and behavior. The mechanisms of circadian clocks are well understood in young fruit flies Drosophila melanogaster, but less is known about how circadian system changes during organismal aging. Similar

Journal of NanobiotechnologyNanocatalysis coupled with photothermal therapy is a potent anti-cancer approach, yet its clinical utility is limited by low concentration of tumor substrate, redox interference, and risks of overheating normal tissues.

Circadian Rhythm Disruption [PDF]
AAOHN Journal, 2011 The circadian rhythm is a 24-hour cycle subject to outside influences. Disruptions of this cycle (e.g., shift work and international travel) have implications for occupational health nurses.

Molecular Oncology, EarlyView.This article advocates integrating temporal dynamics into cancer research. Rather than relying on static snapshots, researchers should increasingly consider adopting dynamic methods—such as live imaging, temporal omics, and liquid biopsies—to track how tumors evolve over time.

Desynchrony and synchronisation underpinning sleep-wake cycles [PDF]
arXiv, 2021 A biophysical model of arousal dynamics is used to study mechanisms of synchronisation and loss of synchrony among the three key oscillators controlling sleep-wake cycles: the circadian, homeostatic, and light oscillators. Synchronisation of these rhythms promotes sleep and brain clearance and is critical for human health. Conversely, their desynchrony
