Coupling governs entrainment range of circadian clocks

Molecular Systems Biology, 2010
Circadian clocks are endogenous oscillators driving daily rhythms in physiology and behavior. Synchronization of these timers to environmental light–dark cycles (‘entrainment’) is crucial for an organism's fitness.

Copy number variations in healthy subjects. Case study: iPSC line CSSi005-A (3544) production from an individual with variation in 15q13.3 chromosome duplicating gene CHRNA7 [PDF]

, 2018
CHRNA7, encoding the neuronal alpha7 nicotinic acetylcholine receptor (a7nAChR), is highly expressed in the brain, particularly in the hippocampus. It is situated in the 15q13.3 chromosome region, frequently associated with a Copy Number Variation (CNV),

A review of psychosocial factors and personality in the treatment of obstructive sleep apnoea

European Respiratory Review, 2019
Effective treatment of obstructive sleep apnoea (OSA) is primarily determined by adherence to the selected intervention. The most common treatment pathways are mechanical devices such as continuous positive airway pressure (CPAP) or a mandibular ...

Regulation of pupil size in natural vision across the human lifespan

Royal Society Open Science
Vision is mediated by light passing through the pupil, which changes in diameter from approximately 2 to 8 mm between bright and dark illumination. With age, mean pupil size declines.

Eating on nightshift: A big vs small snack impairs glucose response to breakfast

Neurobiology of Sleep and Circadian Rhythms, 2018
Shift work is a risk factor for chronic diseases such as Type 2 diabetes. Food choice may play a role, however simply eating at night when the body is primed for sleep may have implications for health.

Uncorrelated Age-Related Changes in Visuo-Spatial Working Memory Binding and Thermoregulation

Clocks & Sleep
Ageing is associated with alterations in circadian rhythms and thermoregulation, contributing to a fragmentation of the sleep–wake cycle and possibly age-related changes in cognitive performance.
