Sleep–wake rhythm and its association with lifestyle, health-related quality of life and academic performance among Japanese nursing students: a cross-sectional study

BMC Nursing, 2021
Background Young adults are likely to have activities and go to bed late at night due to their age-dependent delayed endogenous circadian clock. The purpose of the present study was to clarify sleep–wake rhythm and its association with lifestyle, health ...

Weight loss and metabolic improvements dominate the microbiome response in the MIND diet intervention: a randomized controlled trial

Alzheimer's &Dementia: Translational Research &Clinical Interventions, Volume 12, Issue 2, April/June 2026.
Abstract INTRODUCTION Observational studies link the MIND diet to reduced risk of Alzheimer's disease (AD) and slower cognitive decline. However, a recent randomized controlled trial found no differential cognitive benefit of the MIND diet over a control diet in the context of shared caloric restriction.

Chronic Night Shift Is More Detrimental Than Chronic Light at Night on Circadian Rhythmicity and Metabolic Health in a Female Diurnal Rodent

The FASEB Journal, Volume 40, Issue 6, 31 March 2026.
To dissociate the effects induced by artificial indoor light at night from those induced by circadian desynchronization, females of the diurnal rodent, Arvicanthis ansorgei, were exposed to chronic indoor light at night (mimicking nightwork) or to chronic night shift (mimicking shiftwork).

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, Volume 600, Issue 6, Page 765-792, March 2026.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, Volume 600, Issue 6, Page 808-836, March 2026.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Structural analysis of socioeconomic factors and school jet lag in traumatic dental injury among children [PDF]

Brazilian Oral Research
The objective of this study was to analyze the directions by which school jet lag is associated with traumatic dental injury in children, evaluating direct and indirect effects of socioeconomic factors and sleep. A representative, population-based, cross-

Obesity and sleep disturbance: the chicken or the egg? [PDF]

, 2018
Epidemiological studies suggested an association between obesity and sleep disturbances. Obstructive sleep apnea is the most prevalent type of obesity-related sleep disorder that lead to an increased risk for numerous chronic health conditions.

Post‐Translational Modifications in Animal Circadian Clocks

Advanced Science, Volume 13, Issue 16, 18 March 2026.
Circadian clocks coordinate physiology with daily environmental cycles through conserved transcriptional–translational feedback loops. This review summarizes how post‐translational modifications fine‐tune clock function, highlights the evolutionary convergence of circadian timekeeping in Drosophila and mammals, and emphasizes the central of these ...
