Sleep Apnea and Paroxysmal Atrial Fibrillation: Diurnal Patterning of Autonomic Dysfunction and Influence of CPAP Therapy

open access: yesJournal of Arrhythmia, Volume 42, Issue 3, June 2026.
Autonomic dysfunction in sleep apnea shows diurnal variation, with stronger associations between SDB severity and HRV during wakefulness than sleep. CPAP therapy induces complex, state‐dependent changes in HRV, suggesting that daytime autonomic alterations may better reflect sustained cardiovascular risk in patients with paroxysmal atrial fibrillation.

Chronobiology and psychiatry : development of a conceptual model and integrative approach for South African psychiatrists

open access: yes, 2004
Bibliography: leaves 78-91.Chronobiology developed slowly after it was recognised that rhythmicity was a fundamental property of life. However, the principles of chronobiology are not well integrated in clinical practice.

Bile acid metabolism and sleep: Mechanistic interplay and clinical implications of the gut–liver–brain axis

open access: yesSleep Research, Volume 3, Issue 2, Page 170-179, June 2026.
Abstract The bidirectional interplay between sleep and metabolic homeostasis is fundamental to physiological health. While the roles of glucose and lipid metabolism in sleep regulation have been extensively characterized, bile acids (BAs), which are traditionally viewed as digestive surfactants, are emerging as critical metabolic messengers with ...

A Conserved Circadian Function for the Neurofibromatosis 1 Gene

open access: yesCell Reports, 2018
Summary: Loss of the Neurofibromatosis 1 (Nf1) protein, neurofibromin, in Drosophila disrupts circadian rhythms of locomotor activity without impairing central clock function, suggesting effects downstream of the clock.

Circadian Clock Regulates Epidermal Endocrine System in Homeostatic Skin Pigmentation

open access: yesExperimental Dermatology, Volume 35, Issue 6, June 2026.
ABSTRACT The circadian clock regulates multiple physiological processes in the skin, including local hormone synthesis and pigmentation. However, how circadian regulation interacts with epidermal endocrine signalling in melanocytes remains unclear.

Imaging Multidimensional Therapeutically Relevant Circadian Relationships

open access: yesInternational Journal of Biomedical Imaging, 2009
Circadian clocks gate cellular proliferation and, thereby, therapeutically target availability within proliferative pathways. This temporal coordination occurs within both cancerous and noncancerous proliferating tissues.

Sleep Deprivation in Mice: Looking Beyond the Slow Wave Rebound

open access: yesJournal of Sleep Research, Volume 35, Issue 3, June 2026.
ABSTRACT Sleep is a fundamental process supporting the dynamic regulation of neural function. Emerging methods have proposed that the aperiodic components of brain signals (such as the spectral slope, spectral intercept, and spectral knee), in addition to entropy‐based measures, offer robust empirical markers of neural states.
