26. Adjuvant effects of classical music on simvastatin induced reduction of anxiety but not object recognition memory in rats
Simvastatin is one of many hydroxymethylglutaryl-coenzyme-A reductase inhibitors that are prescribed to lower cholesterol. Some emerging evidence indicates that classical music can serve as an effective adjuvant in rats treated with simvastatin. Moreover, simvastatin and classical music have been shown to influence some cognitive functions. To further unders

27. Phytoestrogen -zearalanol ameliorates memory impairment and neuronal DNA oxidation in ovariectomized mice
OBJECTIVE: The aim of this study was to evaluate the effect of a novel phytoestrogen, α-Zearalanol, on Alzheimer's disease-related memory impairment and neuronal oxidation in ovariectomized mice. METHODS: Female C57/BL6 mice were ovariectomized or received sham operations and treatment with equivalent doses of 17β-estradiol or α-Zearalanol for 8 weeks.

28. Learning and survival memory undergoing a permanent bilateral carotid ligation in rats
PURPOSE: To evaluate the effect of cerebral hypoxia-ischemia on memory and learning survival of rats submitted to permanent bilateral carotid ligation (PBCL). METHODS: Twenty-four survivors of PBCL were evaluated after 30 days with regard to memory and learning using a water survival maze. Twenty-three healthy rats were used as control group. The results wer

29. Efeitos da administração de ácido fólico sobre parâmetros comportamentais, bioquímicos e morfológicos em ratos submetidos à hipóxia-isquemia encefálica neonatal
Perinatal hypoxic-ischemic (HI) is a significant cause of mortality and morbidity in infants and young children. Folic acid is a water soluble vitamin that can be obtained through diet and has been related to the antioxidant effect, protecting ischemic events and Alzheimer s disease. The aim of this study was to investigate the role of the folic acid treatme

32. Ferramenta de auxílio no processo ensino-aprendizagem: eficácia da utilização de kit educacional no primeiro ano do ensino médio na disciplina de química
Uma das dificuldades encontradas no ensino da Química é o estabelecimento de relações entre representações do nível microscópico e as do macroscópico na exploração de um conceito. Estudos anteriores mostraram que a utilização de ferramentas de visualização computacional ou física resulta em aprendizado mais efetivo de conceitos. Acredita-se q

33. Del desapego al desenganche y de este al fracaso escolar
Dichotomies such us success/failure, retention/dropping out etc. may have the virtue of the simplification of some questions, as well as allow spatial and temporal comparisons, but they also present the shortcoming of disdaining details and nuances, as the spectrum of performances, attitudes and responses of pupils in school is, to be true, immensely more ri

34. Impairment of spatial performance by continuous intensive noise: a behavioral view
A wide range of animal and human investigations have tested the neurobiological and immunological aspects of noise. Few studies, however, have explored the behavioral characteristics of noise on neuromotor movements. To examine this correlation, we tested the effects of continuous intensive noise on retention and contextual transfer in a spatial memory task

35. Differentiation of MDMA or 5-MeO-DIPT induced cognitive deficits in rat following adolescent exposure
The so-called "club drug" Foxy or Methoxy Foxy (5-Methoxy-N,N-di(iso)propyltryptamine hydrochloride; 5-MeO-DIPT) is a newer drug of abuse that has recently gained in popularity among recreational users as an alternative to MDMA (Ecstasy). While considerable research into the consequences of MDMA use is available, much remains unknown about the neurobiologica
