Chronic Circadian Misalignment Disrupts the Circadian Clock and Promotes Metabolic Syndrome
… in the United States and worldwide. Chronic misalignment of an organism’s internal circadian clock with diurnal, cyclic changes in the external environment, prevalent in professions that require shift work, contributes significantly to Type 2 Diabetes development. Experimentally, only …

The effect of circadian regulation and sleep disruption on metabolic homeostasis
Sleep and circadian disruption are ubiquitous in modern society. While the National Sleep Foundation recommends adults sleep 7-9 hours per night, the average sleep duration of American adults has decreased from ~8.8 hours to ~6.8 hours over the last century, with 1 in 3 people report sleeping fewer …

Chronic Circadian Disruption Alters Behaviour, Cardiac Function and Glucose Regulation in Mice
The circadian system regulates many physiological functions including the cardiovascular system, metabolism, and stress response. Accordingly, circadian misalignment in mammals contributes to cardiometabolic disease and stress-induced emotional disorders. The BTBR mouse strain shows several …

Evaluating sleep and circadian rhythm disturbances and symptoms of impulsivity and inattention: Implications for adult attention-deficit/hyperactivity disorder
… evidence pointing to dysfunction of the circadian timing system in ADHD, and individual differences in human chronotype and diurnal preference have been linked with impulsivity and attention problems in adults. In the work presented here we examined associations between a later circadian …

FROM CLOCKS TO EXERCISE, FROM METABOLISM TO PERFORMANCE: A CHRONOPHYSIOLOGICAL APPROACH
… crucial in regulating metabolic processes and circadian rhythms. Then, experimental studies are presented, which demonstrate the effects of sleep impairments, circadian misalignment, and chronotype on aerobic capacity, motor skills, and postural control in athletes. Additionally, studies on …

Fatigue Risk Management: Modeling the Sleep/Wake-Based Dynamics of Performance
… performance impairment due to sleep loss and/or circadian misalignment. In essence, these models are all based on the Two-Process Model (TPM) which contains a homeostatic process for the build-up and decline of sleep pressure across days, and a circadian process to keep track of time of day. The …

The Effect of General Anaesthesia on Circadian Rhythms in Mice
… anaesthesia), patients often report symptoms of circadian misalignment that can last up to five days. Animal studies have now demonstrated that GA may be, at least in part, responsible for these effects, causing timedependent shifts on circadian rhythms of behaviour, physiology, and cognitive …

Towards an understanding of the relationship between sleep and cardiovascular disease risk in adults of African descent living in a low socioeconomic status community
… may be too early, potentially contributing to circadian misalignment, which in turn may increase CVD risk. We further hypothesise that when faced with these adverse neighbourhood conditions, some residents may be in a state of hypervigilance at night, resulting in insufficient sympathetic …
