    • Age-related changes during a paradigm of chronic sleep restriction 

      Souza, Luciane de [UNIFESP]; Andersen, Monica L. [UNIFESP]; Smaili, Soraya Soubhi [UNIFESP]; Lopes, Guiomar S. [UNIFESP]; Ho, Priscila S. [UNIFESP]; Papale, Ligia A. [UNIFESP]; Tufik, Sergio [UNIFESP] (Elsevier B.V., 2010-12-10)
      Fragmented and restricted sleep is a common problem for the human elderly. There is evidence that aging impairs sleep in animals as well. After sleep deprivation, older animals have less sleep rebound. Despite increasing ...

    • Analysis of clinical characteristics and risk factors for mortality in human status epilepticus 

      Garzon, Eliana [UNIFESP]; Fernandes, Regina Maria França; Sakamoto, Américo Ceiki [UNIFESP] (W B Saunders Co Ltd, 2003-09-01)
      Purpose: To analyse clinical data including aetiology, age, antecedents, classification and mortality in human status epilepticus (SE), and to assess prognostic factors for mortality.Methods: A prospective study was ...

    • Atypical clinical and electroencephalographic pattern in a patient with subacute sclerosing panencephalitis 

      Silva, Délrio F. [UNIFESP]; Lima, Márcia Marques; Anghinah, Renato; Zanoteli, Edmar [UNIFESP]; Lima, José Geraldo Camargo [UNIFESP] (Academia Brasileira de Neurologia - ABNEURO, 1995-06-01)
      We describe an atypical clinical and electroencephalographic (EEG) pattern observed during the course of subacute sclerosing panencephalitis in a 14 year-old boy. In this patient with a two weeks history of partial complex ...

    • Atypical EEG pattern in children with absence seizures 

      Silva, Délrio F. [UNIFESP]; Lima, Márcia Marques; Anghinah, Renato; Zanoteli, Edmar [UNIFESP]; Lima, José Geraldo Camargo (Academia Brasileira de Neurologia - ABNEURO, 1995-06-01)
      We studied four children with diagnosis of absence seizures (generalized primary epilepsy), and with a generalized delta activity on the EEG during clinical attacks provoked by hyperventilation. The lack of ictal generalized ...

    • Atypical pattern related to 14 Hz positive spikes 

      Silva, Délrio F. [UNIFESP]; Lima, Márcia Marques; Kanda, Paulo M.; Anghinah, Renato; Zanoteli, Edmar [UNIFESP]; Lima, José Geraldo C. [UNIFESP] (Academia Brasileira de Neurologia - ABNEURO, 1995-06-01)
      We studied two children with a history of headache and a normal physical and neurological examination whose EEG showed an electroencephalographic pattern recently published, the N-shape potential associated with the 14 Hz ...

    • Background and paroxystic activities on AIDS patients' EEG: relation with urea and creatinine seric concentration 

      Prado, Gilmar Fernandes do [UNIFESP]; Silva, Ademir Baptista [UNIFESP]; Coelho, João Fernando Guimbra Simões; Braga, Nádia Iandoli Oliveira; Accetturi, Conceicao Aparecida [UNIFESP]; Lima, José Geraldo de Camargo [UNIFESP] (Academia Brasileira de Neurologia - ABNEURO, 1998-09-01)
      The HIV is responsible for important metabolic and structural alterations of the brain. This affected brain must react to continuous systemic metabolic fluctuations. We search for possibly resulting cerebral electric ...

    • Brain-Derived Neurotrophic Factor Gene Polymorphism Predicts Interindividual Variation in the Sleep Electroencephalogram 

      Guindalini, Camila [UNIFESP]; Mazzotti, Diego R. [UNIFESP]; Castro, Laura S. [UNIFESP]; D'Aurea, Carolina V. R. [UNIFESP]; Andersen, Monica L. [UNIFESP]; Poyares, Dalva [UNIFESP]; Bittencourt, Lia R. A. [UNIFESP]; Tufik, Sergio [UNIFESP] (Wiley-Blackwell, 2014-08-01)
      Previous studies have suggested that brain-derived neurotrophic factor (BDNF) participates in the homeostatic regulation of sleep. the objective of this study was to investigate the influence of the Val66Met functional ...

    • A comparison between averaged spikes and individual visually-analyzed spikes in rolandic epileptiform discharges 

      Braga, Nadia I.o. [UNIFESP]; Manzano, Gilberto Mastrocola [UNIFESP]; Nóbrega, João Antonio Maciel [UNIFESP] (Academia Brasileira de Neurologia - ABNEURO, 2002-09-01)
      PURPOSE:This study compared some morphological features of individual rolandic epileptiform discharges, used to obtain an averaged estimate, with those of the resulting estimate. METHOD: Twenty-four averaged discharges ...

    • Complex partial status epilepticus in a child 

      Silva, Délrio F. [UNIFESP]; Zanoteli, Edmar [UNIFESP]; Lima, Márcia Marques; Anghinah, Renato; Lima, José Geraldo Camargo [UNIFESP] (Academia Brasileira de Neurologia - ABNEURO, 1995-06-01)
      Complex partial status epilepticus (SE) has been reported rarely in children. We describe the clinical case of a 14 year-old girl with complex partial seizures (CPS) since age 10 who developed a complex partial SE probably ...

    • Cyclooxygenase-2/PGE(2) pathway facilitates pentylenetetrazol-induced seizures 

      Oliveira, Mauro Schneider; Furian, Ana Flavia; Freire Royes, Luiz Fernando; Fighera, Michele Rechia; Fiorenza, Natalia Gindri; Castelli, Marcelo; Machado, Pablo; Bohrer, Denise; Veiga, Marlei; Ferreira, Juliano; Cavalheiro, Esper Abraao [UNIFESP]; Mello, Carlos Fernando (Elsevier B.V., 2008-03-01)
      Cyclooxygenases (CCXs) are rate-limiting enzymes in the metabolic pathways in which arachidonic acid is converted to prostaglandins. COX-2 is the isoform induced at injury/inflammation sites and expressed constitutively ...
