(Amer Acad Sleep Medicine, 2001-04-15)
Sleep rebound in animals deprived of paradoxical sleep by the modified multiple platform method
(Elsevier B.V., 2000-09-01)
The objective of the present study was to assess the sleep rebound of animals exposed to the modified multiple platform method (MMPM), in which cage-mate rats were placed onto narrow platforms (NP=6.5 cm in diameter), onto ...
Distinct effects of acute and chronic sleep loss on DNA damage in rats
(Elsevier B.V., 2009-04-30)
The aim of this investigation was to evaluate genetic damage induced in male rats by experimental sleep loss for short-term (24 and 96 h) and long-term (21 days) intervals, as well as their respective recovery periods in ...
Paradoxical sleep deprivation: neurochemical, hormonal and behavioral alterations. Evidence from 30 years of research
(Academia Brasileira de Ciências, 2009-09-01)
Sleep comprises approximately one-third of a person's lifetime, but its impact on health and medical conditions remains partially unrecognized. The prevalence of sleep disorders is increasing in modern societies, with ...
Endocrinological and catecholaminergic alterations during sleep deprivation and recovery in male rats
(Blackwell Publishing Ltd, 2005-03-01)
Since previous data of our group showed increased concentrations in HPA axis hormones in sleep deprived rats, we hypothesized that this augmentation could produce effects in other hormonal systems, particularly in the ...
Anxiety-like effects of meta-chlorophenylpiperazine in paradoxically sleep-deprived mice
(Elsevier B.V., 2014-03-03)
Chlorophenylpiperazines (CPP) are psychotropic drugs used in nightclub parties and are frequently used in a state of sleep deprivation, a condition which can potentiate the effects of psychoactive drugs. This study aimed ...
