SODIUM DICLOFENAC INHIBITS HYPERTHERMIA-INDUCED BY PARADOXICAL SLEEP-DEPRIVATION - the POSSIBLE PARTICIPATION of PROSTAGLANDINS
(Elsevier B.V., 1993-11-01)
Sodium diclofenac inhibits hyperthermia induced by paradoxical sleep deprivation (PSD), which suggests the participation of prostaglandins. the temperature of paradoxical sleep-deprived rats increased from the first to the ...
Paradoxical sleep deprivation facilitates subsequent corticosterone response to a mild stressor in rats
(Elsevier B.V., 2002-03-01)
The pituitary-ad renal responsiveness to a mild stressor was assessed in rats that were deprived of paradoxical sleep (PS) and in controls that were not deprived. Animals were either individually- or group-deprived for 96 ...
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 ...
Grooming analysis algorithm: Use in the relationship between sleep deprivation and anxiety-like behavior
(Elsevier B.V., 2013-03-05)
Increased anxiety is a classic effect of sleep deprivation. However, results regarding sleep deprivation-induced anxiety-like behavior are contradictory in rodent models. the grooming analysis algorithm is a method developed ...
Sleep homeostasis in rats assessed by a long-term intermittent paradoxical sleep deprivation protocol
(Elsevier B.V., 2005-05-28)
Numerous studies have evaluated the sleep homeostasis of rats after short- or long-periods of sleep deprivation, but none has assessed the effects of prolonged sleep restriction on the rat's sleep pattern. the purpose of ...
Paradoxical sleep deprivation increases plasma endothelin levels
(Associação Brasileira de Divulgação Científica, 2002-01-01)
The endothelins (ET-1, 2 and 3) constitute a family of 21 amino acid peptides with potent biological activities. ET-1 is one of the most potent endogenous vasoconstrictors so far identified and its increased concentration ...
Effects of cocaine, methamphetamine and modafinil challenge on sleep rebound after paradoxical sleep deprivation in rats
(Associação Brasileira de Divulgação Científica, 2008-01-01)
Sleep loss is both common and critically relevant to our society and might lead to the abuse of psychostimulants such as amphetamines, cocaine and modafinil. Since psychoactive substance abuse often occurs within a scenario ...
Effects of sleep loss on sleep architecture in Wistar rats: Gender-specific rebound sleep
(Elsevier B.V., 2008-05-15)
This study was designed to examine the influence of gender on sleep rebound architecture after a 4-day paradoxical sleep deprivation period. After a 5-day baseline sleep recording, both male and female rats in different ...
Influence of food restriction on lipid profile and spontaneous glucose levels in male rats subjected to paradoxical sleep deprivation
(Faculdade de Medicina / USP, 2012-01-01)
OBJECTIVES: The purpose of this study was to determine the paired consequences of food restriction and paradoxical sleep deprivation on lipid profile and spontaneous glucose levels in male rats. METHOD: Food restriction ...
Inhibitory effect of GABAergic drugs in cocaine-induced genital reflexes in paradoxical sleep-deprived male rats
(Elsevier B.V., 2004-06-01)
The aim of this study was to seek whether GABAergic drugs were involved in the action of cocaine on spontaneous genital reflexes (penile erection-PE, and ejaculation-EJ) of paradoxical sleep-deprived (PSD) male rats. After ...
