Elementos psicomotores e fatores sociais relacionados ao desenvolvimento motor e dificuldades de aprendizagem em crianças ingressantes no ensino fundamental

In humans, psychic and motor skills are interdependent, and therefore, cannot fail to take into account the influence of a good psychomotor development in the prevention of learning difficulties. Another factor that interferes with the learning process is the social. Family problems, socioeconomic status of the child, among others, may be associated with learning difficulties and, consequently, the student's performance. Therefore, the aim of this study was to investigate through the elements of psychomotor, if a delay in neuropsychomotor development may be related to the presence of learning problems in children entering elementary school. Also, determine whether there were differences regarding the presence or absence of these difficulties in students from middle and low social class and have family problems or not. For this, we analyzed two classes of 49 students from 1 year of elementary education at a public school in the city of Bauru/SP, aged between 6 and 7 years. These students were tested for the ENE proposed by Lefèvre (1976) to assess the maturity of the nervous system. A pre-designed questionnaire was answered by the teachers of classes to know students' academic performance, learning difficulties presented by them, social status and the presence of family problems. All students participating in the survey had the term sheet signed by the parents, allowing participation in the study. To reach the results, we applied the Anova and Tukey test for comparison analysis of mean age in the performance of ENE. To investigate the existence of a relationship between performance in the ENE and learning difficulties, we used the calculation of Pearson correlation. To analyze the difference in average scores of learning disabilities in students from different social classes and among those who had family problems or not, comparative graphs were used with the averages obtained from the questionnaire answered by the teachers for each learning...

Immunohistochemical approach to the pathogenesis of clinical cases of bovine Herpesvirus type 5 infections

Meningoencephalitis by Herpesvirus type 5 (BoHV-5) in cattle has some features that are similar to those of herpetic encephalitis in humans and other animal species. Human Herpesvirus 3 (commonly known as Varicella-zoster virus 1), herpes simplex viruses (HSV), and equid Herpesvirus 1 (EHV-1) induce an intense inflammatory, vascular and cellular response. In spite of the many reports describing the histological lesions associated with natural and experimental infections, the immunopathological mechanisms for the development of neurological disorder have not been established. A total of twenty calf brains were selected from the Veterinary School, University of São Paulo State, Araçatuba, Brazil, after confirmation of BoHV-5 infection by virus isolation as well as by a molecular approach. The first part of the study characterized the microscopic lesions associated with the brain areas in the central nervous system (CNS) that tested positive in a viral US9 gene hybridization assay. The frontal cortex (Fc), parietal cortex (Pc), thalamus (T) and mesencephalon (M) were studied. Secondly, distinct pathogenesis mechanisms that take place in acute cases were investigated by an immunohistochemistry assay. This study found the frontal cortex to be the main region where intense oxidative stress phenomena (AOP-1) and synaptic protein expression (SNAP-25) were closely related to inflammatory cuffs, satellitosis and gliosis, which represent the most frequently observed neurological lesions. Moreover, MMP-9 expression was shown to be localized in the leptomeninges, in the parenchyma and around mononuclear infiltrates (p < 0.0001). These data open a new perspective in understanding the role of the AOP-1, MMP-9 and SNAP-25 proteins in mediating BoHV-5 pathogenesis and the strategies of host-virus interaction in order to invade the CNS.

Sensibilização comportamental ao etanol e neuroadaptações envolvendo a proteína (DELTA)FOSB: efeitos do tratamento com N-Acetilcisteína em camundongos

Pharmacological treatments currently used in ethanol addiction are inefficient, requiring new drugs for this purpose. The pro-drug N-Acetylcysteine (N-Ac) has shown efficacy in the treatment of addiction to cocaine and nicotine in preclinical research and clinical pilot studies. When administered, N-Ac is subsequently converted to cysteine, and cystine, which has an action on the central nervous system. However, there are few data about the possible application of N-Ac in the ethanol addiction. Behavioral sensitization is the gradual increase of the psychostimulant effects induced by repeated administration of drugs of abuse, including ethanol, and its development has been linked to important neuroadaptations in addiction. These neuroadaptations occur in neural circuits that mediate the reinforcing properties of these drugs and may involve several proteins. The ΔFosB protein accumulates in neurons after repeated activation and mediates long lasting changes in response to drugs of abuse. These changes are manifested mainly in the nucleus accumbens (Acb) and prefrontal cortex (PFC) neurons. The aim of the study was to evaluate the effects of N-Ac treatment in the development of ethanol behavioral sensitization and in alterations in the ΔFosB protein in mice. Swiss male mice were exposed to a standardized behavioral sensitization protocol to the experimental conditions of the laboratory and treated with N-Ac. At the end of behavioral sensitization procedure, animals were euthanized and their brains removed for ΔFosB quantification by Western blotting. Two experiments of behavioral sensitization were performed to the standardization of the protocol. The first, although effective in demonstrating the development of behavioral sensitization, was not effective in allowing the evaluation of the expression of the behavioral sensitization. The age of the animals and the conditions of luminosity and color of locomotion apparatus were changed and a new...
