Abstract Introduction Despite the efficacy of cognitive behavioural therapy for insomnia (CBT-I) treating youth insomnia, there remain individual differences in treatment outcomes. Previous studies found that demographic (e.g., age) and clinical features depression, anxiety) could potentially affect responses adults but has been limited research conducted youth. This study aimed to identify pot...

Abstract Introduction As individuals age, the circadian-driven timing of their sleep shifts to an earlier hour. Whether such a shift moderates effectiveness insomnia treatment on disturbances and mood in older adults is unknown. Methods We tested hypothesis that circadian preference improvements symptoms following non-pharmacological treatment. Older (N=111, age=69±6.4 years, female=65%) with (...

The giant Zambian mole rat (Fukomys mechowii) is a subterranean Afrotropical rodent noted for its regressed visual system and unusual patterns of circadian rhythmicity--within this species some individuals exhibit distinct regular circadian patterns of locomotor activity while others have arrhythmic circadian patterns. The current study was aimed at understanding whether differences in circadia...

University days generally start at fixed times in the morning, often early morning, without regard to optimal functioning times for students with different chronotypes. Research has shown that later starting times are crucial to high school students' sleep, health, and performance. Shifting the focus to university, this study used two new approaches to determine ranges of start times that optim...

INTRODUCTION The aim of this study was to investigate the association between the variation in expression profile of clock genes and obesity using peripheral blood mononuclear (PMN) cells. MATERIAL AND METHODS The subjects comprised 10 obese patients and 10 healthy volunteers. Blood was collected at different time-points during the day and levels of blood sugar, IRI, adiponectin and leptin we...

The paper examines the annual profile of fluctuating microalternations some ECG parameters in healthy students who live northern conditions and have different chronotypes. main method research was dispersion mapping that helped assess energy metabolic processes myocardium. Among male female students, 14,3% had morning chronotype, 50,7% arrhythmic 35% evening chronotype. Previously published res...
