The added value of dim light melatonin onset in diagnosing idiopathic delayed sleep phase disorder
Sleep Science, 2011 Delayed sleep phase disorder (DSPD) is characterized by delayed sleep-wake rhythm and is associated with a delayed melatonin secretion. The diagnosis of DSPD is based on clinical history, supported by actigraphy monitoring and sleep diary.

Chronothyroidology: Chronobiological Aspects in Thyroid Function and Diseases
Life, 2021 Chronobiology is the scientific discipline which considers biological phenomena in relation to time, which assumes itself biological identity. Many physiological processes are cyclically regulated by intrinsic clocks and many pathological events show a ...

Light therapy for the treatment of delayed sleep-wake phase disorder in adults: a systematic review [PDF]
Sleep Science, 2021 Delayed sleep-wake phase disorder (DSWPD) is characterized by sleep onset times, beyond the usual schedules and social conveniences, which potentially impacts on health as well as on school and professional performance.

Rodent models for the analysis of tissue clock function in metabolic rhythms research [PDF]
, 2017 The circadian timing system consists on a distributed network of cellular clocks that together coordinate 24-h rhythms of physiology and behavior. Clock function and metabolism are tightly coupled, from the cellular to the organismal level.

Daily circadian misalignment impairs human cognitive performance task-dependently
Scientific Reports, 2018 Shift work increases the risk for human errors, such that drowsiness due to shift work has contributed to major industrial disasters, including Space Shuttle Challenger, Chernobyl and Alaska Oil Spill disasters, with extraordinary socio-economical costs.

An end-to-end framework for real-time automatic sleep stage classification. [PDF]
, 2018 Sleep staging is a fundamental but time consuming process in any sleep laboratory. To greatly speed up sleep staging without compromising accuracy, we developed a novel framework for performing real-time automatic sleep stage classification.

Biological Effects of Space Hypomagnetic Environment on Circadian Rhythm
Frontiers in Physiology, 2021 The intrinsic earth magnetic field (geomagnetic field, GMF) provides an essential environmental condition for most living organisms to adapt the solar cycle by rhythmically synchronizing physiological and behavioral processes. However, hypomagnetic field
