    • Acute total sleep deprivation potentiates amphetamine-induced locomotor-stimulant effects and behavioral sensitization in mice 

      Saito, Luis P. [UNIFESP]; Fukushiro, Daniela F. [UNIFESP]; Hollais, Andre W. [UNIFESP]; Mari-Kawamoto, Elisa [UNIFESP]; Costa, Jacqueline M. [UNIFESP]; Berro, Lais F. [UNIFESP]; Aramini, Tatiana C. F. [UNIFESP]; Wuo-Silva, Raphael [UNIFESP]; Andersen, Monica L. [UNIFESP]; Tufik, Sergio [UNIFESP]; Frussa-Filho, Roberto [UNIFESP] (Elsevier B.V., 2014-02-01)
      It has been demonstrated that a prolonged period (48 h) of paradoxical sleep deprivation (PSD) potentiates amphetamine (AMP)-induced behavioral sensitization, an animal model of addiction-related neuroadaptations. in the ...

    • Avaliação das alterações das atividades de metalopeptidases no sistema nervoso central em modelos de privação de sono 

      Visniauskas, Bruna [UNIFESP] (Universidade Federal de São Paulo (UNIFESP), 2010-04-28)
      Neuropeptides have a fundamental role on sleep-wake cycle control and their actions are regulated by proteolytic processing. Proteolytic enzymes are essential for the metabolism of neuropeptides, either by release from ...

    • Cholinergic mechanisms in cocaine-induced genital reflexes in paradoxical sleep-deprived male rats 

      Andersen, Monica Levy [UNIFESP]; Papale, Ligia Assumpção [UNIFESP]; Tufik, Sergio [UNIFESP] (Elsevier B.V., 2004-03-01)
      In view of the fact that paradoxical sleep deprivation (PSD) modifies cocaine-induced genital reflexes (penile erection [PE] and ejaculation [EJ]), the aim of this study was to address the interaction of cholinergic agents ...

    • Chronic stress during paradoxical sleep deprivation increases paradoxical sleep rebound: Association with prolactin plasma levels and brain serotonin content 

      Machado, Ricardo Borges [UNIFESP]; Tufik, Sergio [UNIFESP]; Suchecki, Deborah [UNIFESP] (Elsevier B.V., 2008-10-01)
      Previous studies suggest that stress associated to steep deprivation methods can affect the expression of steep rebound. in order to examine this association and possible mechanisms, rats were exposed to footshock stress ...

    • Cocaine-induced genital reflexes during paradoxical sleep deprivation and recovery 

      Andersen, Monica Levy [UNIFESP]; Bignotto, Magda [UNIFESP]; Tufik, Sergio [UNIFESP] (Elsevier B.V., 2003-02-01)
      Paradoxical sleep deprivation (PSD) for 96 h together with cocaine administration elicits genital reflexes (penile erection [PE] and ejaculation [EJ]) in rats. Our objective was to examine genital reflexes after periods ...

    • Different stress modalities result in distinct steroid hormone responses by male rats 

      Andersen, Monica Levy [UNIFESP]; Bignotto, Magda [UNIFESP]; Machado, Ricardo Borges [UNIFESP]; Tufik, Sergio [UNIFESP] (Associação Brasileira de Divulgação Científica, 2004-06-01)
      Since both paradoxical sleep deprivation (PSD) and stress alter male reproductive function, the purpose of the present study was to examine the influence of PSD and other stressors (restraint, electrical footshock, cold ...

    • The effect of apomorphine on genital reflexes in male rats deprived of paradoxical sleep 

      Andersen, Monica Levy [UNIFESP]; Bignotto, Magda [UNIFESP]; Tufik, Sergio [UNIFESP] (Elsevier B.V., 2003-11-01)
      Drugs that stimulate dopamine (DA) systems can stimulate sexual arousal in male rats and humans, and previous work has shown that cocaine enhances genital reflexes [penile erection (PE) and ejaculation (EJ)] in rats deprived ...

    • Effect of sildenafil (Viagra®) on the genital reflexes of paradoxical sleep-deprived male rats 

      Andersen, Monica Levy [UNIFESP]; Bignotto, Magda [UNIFESP]; Tufik, Sergio [UNIFESP] (Associação Brasileira de Divulgação Científica, 2007-11-01)
      Since there is evidence that paradoxical sleep deprivation (PSD) elicits penile erection (PE) and ejaculation (EJ), and that the erectile response of rats is mediated by nitric oxide, the present study sought to extend the ...

    • Effects of environmental enrichment and paradoxical sleep deprivation on open-field behavior of amphetamine-treated mice 

      Fukushiro, Daniela Fukue [UNIFESP]; Calzavara, Mariana Bendlin [UNIFESP]; Trombin, Thaís Fernanda [UNIFESP]; Lopez, Giorgia Batlle [UNIFESP]; Abilio, Vanessa Costhek [UNIFESP]; Andersen, Monica Levy [UNIFESP]; Tufik, Sergio [UNIFESP]; Frussa-Filho, Roberto [UNIFESP] (Elsevier B.V., 2007-11-23)
      Background: Environmental enrichment or paradoxical sleep deprivation (PSD) has been shown to modify some responses elicited by drugs of abuse. the aims of the present study were to examine the effects of environmental ...

    • Effects of paradoxical sleep deprivation and cocaine on genital reflexes in hyperlipidic-fed rats 

      Andersen, Monica Levy [UNIFESP]; D'Almeida, Vânia [UNIFESP]; Martins, Paulo José Forcina [UNIFESP]; Antunes, Hanna Karen Moreira [UNIFESP]; Tufik, Sergio [UNIFESP] (Elsevier B.V., 2005-08-01)
      The present study was designed to investigate the effects of a hyperlipidic diet (HD) on penile erection (PE) and ejaculation (EJ) induced by cocaine in paradoxical sleep deprived (PSD) rats. Secondly, we aimed to verify ...
