The aim of the present study was to evaluate whether anxiety and insomnia symptoms, somatic symptoms, and social dysfunction mediate the link between chronotype and suicidality, as depressive symptoms are known to do, among students of the faculties of Medicine and Psychology. Data from a total of 289 students were eligible for the analysis. The st...

Eveningness, as opposed to other chronotypes, in childhood and adolescence is associated with more parental conflicts, such as regarding bed and rising times, which might adversely influence future relationships with parents, and adult attachments. The current survey of 524 Chinese university students (mean = 20.05 and range 18-36 years of age) inv...

Circadian rhythms are an adaptive response of organisms to the environment that enables them to measure time. Circadian rhythms are some of the most studied biological rhythms. Serotonin (5HT) has been proposed as their modulator of circadian rhythms, playing a pivotal role in their establishment. However, 5HT concentrations are altered in insect o...

Both internal (e.g., preferences) and external (e.g., social) factors guide chrononutrition (i.e., the timing of food intake), but the nature and variability of chrononutrition preferences (i.e., preferred timing of food intake) have not been empirically evaluated. The present study aimed to characterize the variability and range of chrononutrition...

Animal and human studies demonstrate anatomical and functional links between the vestibular nuclei and the circadian timing system. This promotes the hypothesis of a circadian rhythm of vestibular function. The objective of this study was to evaluate the vestibular function through the vestibulo-ocular reflex using a rotatory chair at different tim...

This study aimed to examine the reliability and the time-of-day effect of the 505 change of direction (CoD), 10-m sprint, and change of direction deficit test (CoDD). At two different time of days, 39 young diurnally active physical education male students performed different physical tests: 505 CoD, and sprint tests. Measurements were taken at two...

Treatment resistance, medication non-adherence, and side effects of pharmacotherapeutics make treatment difficult in major depressive disorder. Sleep deprivation is a fast-acting and tolerable reinforcement treatment method. In this study, we investigated the effects of late partial sleep deprivation (PSD) therapy added to venlafaxine treatment on ...

The well-known Two-Process Model of Sleep Regulation describes the integration of the circadian rhythm of arousal and sleep - Process C, and the homeostatic pressure to sleep - Process S. Presently, the known biological markers for Process C are melatonin and core body temperature; whereas, for Process S, there is no biological marker except that o...

We have previously shown that quarterly preventive onabotulinumtoxin A (BTA) injections administered to diurnally active patients for chronic migraines (CM) associate with increased discomfort when performed in the morning. The purpose of this study was to further examine if the effectiveness of preventive BTA injections depends on the procedure's ...
