p75NTR Promotes Circadian‐Driven Mineralization During Tooth Development via CK2/PER2 Pathway

Cell Proliferation, EarlyView.
The diagram illustrates how the circadian rhythm regulates the p75NTR‐CK2‐PER2 axis, driving rhythmic biomineralisation during tooth development. ABSTRACT Circadian rhythm is an essential biological process that synchronises physiological activities with environmental light/dark cycles.

The Ecology of Human Sleep (EcoSleep) Cohort Study: Protocol for a longitudinal repeated measurement burst design study to assess the relationship between sleep determinants and outcomes under real‐world conditions across time of year

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary The interplay of daily life factors, including mood, physical activity, or light exposure, influences sleep architecture and quality. Laboratory‐based studies often isolate these determinants to establish causality, thereby sacrificing ecological validity.

Sleep Deprivation in Mice: Looking Beyond the Slow Wave Rebound

Journal of Sleep Research, EarlyView.
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.

On the chronobiology of seasonal affective disorder

, 2002
Chronobiological hypotheses about the pathogenesis of affective disorders have a long history. According to the modern variants, abnormalities of either a sleep-wake cycle dependent process S, or a circadian pacemaker related process C, or an abnor-mal interaction between these two processes underlie the pathogenesis of depres-sion.
