Objectives: Obstructive sleep apnea (OSA) is associated with a variable spectrum of sleep abnormalities and has been connected with memory impairment. The aim of this study was to evaluate the associations between OSA, m...

Sleep is a biological manifestation which there is a periodic alternation between synchronized and desynchronized cerebral electrical activity. Although sleep occupies approximately a third of the human lifespan, the amo...

Neuropeptides have a fundamental role on sleep-wake cycle control and their proteolytic processing regulates their actions. Proteases are essential for the metabolism of neuropeptides, by release either from active or in...

Objectives: The assessment of student achievement in the teaching-learning is a constant concern of the study professors. Actually the night shift is a reality in favor of the persons seeking qualification for a position...

The progress of knowledge in the area of mental health still depends, at least in part, on the development of experimental paradigms using laboratory animals. In such context, sleep deprivation and its effects were propo...

Objectives: The loss of vertical dimension of occlusion (VDO) is a problem that affects stomatognathic system performance, mainly in edentulous patients. Thus, diseases related to musculature failure such as obstructive ...

The aim of this article was the translation into Portuguese of the Brief Infant Sleep Questionnaire (BISC), a tool for screening sleep disorders in infants and toddlers (0-3 years). After obtaining the consent from the a...

Growing evidence is showing important health impacts of sleep disruption. Sleep restriction is becoming increasingly common in today’s 24/7 society. Evidence from epidemiological studies suggest that reduced sleep dura...

Objective: Sleep deprivation and poor quality of sleep are a current issue in our society. In animal models, sleep deprivation can induce diverse alterations, including oxidative stress in several organs. A highly active...

Objective: Ceruloplasmin (Cp) is a copper-binding protein expressed in several tissues that plays distinct functions depending on the physiological context. Recently, increased ceruloplasmin expression in cavernosal tiss...

Frontal and parietal regions are associated with some of the most complex cognitive functions,and several frontoparietal resting state networks can be observed in wakefulness. We used functional magnetic resonance imagin...

Together with the environment, genetic factors can significantly influence sleep and its architecture. Monozygotic twins have greater similarity in terms of latency and duration of sleep cycles than dizygotic twins, in a...

There are emerging links between disturbed sleep and mental illness. These associations may have particular relevance for military populations which are often faced with extremely stressful situations and profound sleep ...

Objectives: Sleep Disordered Breathing (SDB) still remains unrecognized by the medical community, health-care providers and patients despite its high prevalence and association with other major health conditions. The aim...

There is a clear association between primary headaches and sleep disorders, especially when these headaches occur at night or upon waking. The primary headaches most commonly related to sleep are: migraine, cluster heada...

Objective: Paradoxical sleep deprivation increases grooming behaviors in rats. Discordant data on the change promoted by such deprivation on the experimentally defined anxiety levels have made difficult to assess if the ...

The main concepts presented in this review are that sleep is not a function but a state diverse from the waking one. A lot of physiologic functions are carried out during sleep, cardiovascular, respiratory, endocrine, se...

Objective: The objectives of this study were to ascertaining whether sleeping problems affect aggression levels in adult offenders undergoing inpatient psychiatric treatment and exploring the phenomenon in terms of diffe...

Objectives: An association, responsible for affecting circadian rhythms and sleep homeostasis, between PER3 gene variable number tandem repeat (VNTR) and sleep times has been described in humans. The aim of this study wa...

Objectives: Rotating or night shifts elicit rapid changes in physiology which the body cannot quickly adapt. In addition, alterations in shift work influence social and familial aspects that ultimately impact the quality...
