14. 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

16. O impacto da frequência do exercício físico sobre proteínas sinápticas e o comportamento de ratos durante a fase adulta e no envelhecimento
Physical exercise is considered an important alternative in reducing the risk of many diseases and improves the quality of life. These benefits are most evident when the body becomes more vulnerable, either through the natural process of aging or in the onset of neurodegenerative disease. However, the amount of exercise for these benefits is unkwon. Thus, th

17. Influência do ciclo estral no efeito do diazepam na ansiedade e memória de ratas
Memory and anxiety are related phenomena. Several evidences suggest that anxiety is fundamental for learnining and may facilitate or impair the memory formation process depending of the context. The majority of animal studies of anxiety and fear use only males as experimental subjects, while studies with females are rare in the literature. However, the preva

18. Influência da aprendizagem e da manipulação do sistema colinérgico muscarínico na sensibilização ao efeito estimulante do etanol / Influence of learning and cholinergic muscarinic system manipulation on the sensitization to the stimulant effect of ethanol
Diversos autores sugerem que a sensibilização comportamental, caracterizada pelo aumento da atividade psicomotora em resposta à administração repetida de drogas psicoativas, parece desempenhar um papel fundamental no desenvolvimento de abuso e dependência, aumentando a propriedade reforçadora destas substâncias. Animais que desenvolvem sensibilizaç�

19. 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

20. The role of the cerebellum in schizophrenia: from cognition to molecular pathways
Beside its role in motor coordination, the cerebellum is involved in cognitive function such as attention, working memory, verbal learning, and sensory discrimination. In schizophrenia, a disturbed prefronto-thalamo-cerebellar circuit has been proposed to play a role in the pathophysiology. In addition, a deficit in the glutamatergic N-methyl-D-aspartate (NM

21. The modified 2VO ischemia protocol causes cognitive impairment similar to that induced by the standard method, but with a better survival rate
Permanent bilateral occlusion of the common carotid arteries (2VO) in the rat has been established as a valid experimental model to investigate the effects of chronic cerebral hypoperfusion on cognitive function and neurodegenerative processes. Our aim was to compare the cognitive and morphological outcomes following the standard 2VO procedure, in which ther

24. Aplicação de modelos de Markov ocultos na obtenção de taxas de mortalidade das larvas do mosquito da Dengue
In order to prevent the proliferation of Dengue transmitter - scientifically named as Aedes ae- gypti - and therefore decrease human contamination by such insect, many larvaecides have been developed recently. Researchers from Dom Bosco Catholic University evaluate the efectiveness of vegetal-derived substances capable to combat such animal larvae. Death rat
