Anxiogenic effect of sleep deprivation in the elevated plus-maze test in mice
(Springer, 2004-11-01)Rationale: Several clinical studies demonstrate that the absence of periods of sleep is closely related to occurrence of anxiety symptoms. However, the basis of these interactions is poorly understood. Studies performed ...

Comparison of the sleep pattern throughout a protocol of chronic sleep restriction induced by two methods of paradoxical sleep deprivation
(Elsevier B.V., 2006-07-31)The purpose of the present study was to evaluate the sleep homeostasis of rats submitted to a protocol of chronic sleep restriction by two methods and to evaluate the sleep characteristics during the recovery period. the ...

Consequences of subchronic and chronic exposure to intermittent hypoxia and sleep deprivation on cardiovascular risk factors in rats
(Elsevier B.V., 2007-06-15)Since studies suggest that both hypoxia and sleep fragmentation are related to cardiovascular alterations induced by obstructive sleep apnea, the present study was designed to evaluate the effects of hypoxia, sleep ...

Distinct behavioral and neurochemical alterations induced by intermittent hypoxia or paradoxical sleep deprivation in rats
(Elsevier B.V., 2008-01-01)The current study investigated the effects of paradoxical sleep deprivation and intermittent hypoxia by examining whether a combination of the two would induce anxiety-like alterations in behavior. the neurochemical effects ...

(Instituto de Psiquiatria da Universidade Federal do Rio de Janeiro, 2009-01-01)OBJECTIVE: To investigate the sleep duration in adolescents of different socioeconomic status. METHOD: We investigated 863 adolescents from 10 to 19 years in two schools in São Paulo, SP, Brazil. Sleep habits data and ...

EEG recording after sleep deprivation in a series of patients with juvenile myoclonic epilepsy
(Academia Brasileira de Neurologia - ABNEURO, 2005-06-01)Seizures in Juvenile Myoclonic Epilepsy (JME) are dependent on the sleep-wake cycle and precipitant factors, among which sleep deprivation (SD) is one of the most important. Still an under diagnosed syndrome, misinterpretation ...

Efeito da administração de bombesina sobre o desempenho de ratos na tarefa de esquiva inibitória de múltiplas tentativas após privação de sono: interação com o sistema gabaérgico
(Universidade Federal de São Paulo (UNIFESP), 2016-01-03)Several approaches have been used to elucidate mechanisms that are involved in the deleterious effects of sleep deprivation (SD) on the memory processing, such as administration of neuropeptides that modulate neurotransmission ...

Efeitos da privação de sono paradoxal sobre a implantação e a progressão de metástases experimentais em modelo de melanoma murino
(Universidade Federal de São Paulo (UNIFESP), 2015-04-30)Deprivation of REM sleep (PSP) is a stress induction model because it results in a increased concentrations of glucocorticoids (GCs) in humans (cortisol) and rodents (corticosterone) and others neurotransmitters ...

Effect of sleep deprivation on the corticosterone secretion in an experimental model of autoimmune disease
(Karger, 2007-01-01)Objective: Sleep disturbances have been observed in a number of chronic inflammatory conditions, such as systemic lupus erythematosus. Previous results from our laboratory showed that when NZB/NZWF1 mice, an experimental ...

Effects of 3-nitropropionic acid administration on memory and hippocampal lipid peroxidation in sleep-deprived mice
(Elsevier B.V., 2007-01-30)Numerous studies have described memory deficits following sleep deprivation. There is also evidence that the absence of sleep increases brain oxidative stress. the present study investigates the effects of a pro-oxidant ...
