    Purpose: To evaluate the knowledge, attitude and perception of medical students prior to and after a training course about epilepsy. Methods: We used a KAP questionnaire with sixty-one questions which assesses knowledge, attitude and practice of epilepsy. Questionnaires were completed by 185 medical students, before and after epilepsy training. We compared the answers to see whether the lecture had changed the knowledge, attitude and practice in epilepsy. Results: One hundred and six students completed the questionnaire before an eight hour course on epilepsy and 79 students completed the questionnaire one year after the course. Comparison of the knowledge scores prior to (mean=53.9, standard deviation=11.4) and after the course (mean=63.8, standard deviation=11.9) showed that students had improved knowledge after the course (t-test=5.6, p < 0.001). Discussion: Training course on epilepsy for medical students can promote improvement in the knowledge, attitudes and perception regarding epilepsy, which is maintained one year later. These results highlight the importance of continuous educational programs within the Medical Curriculum

    This article aims to identify the debate on the triad economy, energy and environment, providing a greater focus to the issue of climate change. After historically contextualize the economic use of energy and expose the current global energy picture, describes the environmental issue in the light of economic science, stating the two main theoretical approaches of environmental economics. Finally, the article devoted to the important and urgent but controversial debate about the impact of energy model on climate change. Pointed out that, despite a current minority dissenting, the world has significant and reliable evidence that the economic system through several segments, especially the intensive use of energy, may be contributing to the changes in climatic conditions of planet. Energy use and the need to readjust it, both in terms of greater efficiency on the issue of replacing the current fossil energy sources to less carbon-intensive, was one of the main conclusions of the discussion about how to direct the economic system to a path of greater sustainability.energia, meio ambiente, mudanças climáticas.

    Compreender a Recorrência dos Mixomas Cardíacos. Um Caso Clínico

    Recurrence of cardiac myxoma is a rare condition, observed in about 3% of patients in sporadic cases, although it is more frequent in familial ones. Several mechanisms have been proposed to explain such recurrence, and the importance of increased vascularization as a facilitating feature is the subject of debate. The authors report the case of a non-familial right atrial myxoma, unusual for both its histopathology and recurrence

    Distribution of populations of broad-snouted caiman (Caiman latirostris, Daudin 1802, Alligatoridae) in the São Francisco River basin, Brazil

    We surveyed populations of the broad-snouted caiman, Caiman latirostris, throughout the São Francisco River basin, from Três Marias reservoir, State of Minas Gerais, to the river delta, at the boarder of Sergipe and Alagoas states. We registered the occurrence of crocodilians in 61% of all surveyed localities (n = 64), in which the presence of C. latirostris was confirmed in 44% of the surveyed sites. Caimans occurred in both lentic and lotic habitats, although there was a preference for small dams, oxbow lakes and wetlands. Despite the hunting pressure and human impact on natural habitats, our results indicate that the populations of C. latirostris in the São Francisco basin are not fragmented

    Direct determination of molybdenum in polyvitaminic tablets by voltammetry in non-aqueous media.

    Adsorptive stripping voltammetry carried out in a homogeneous ternary solvent composed of N,N-dimethylformamide, water and ethanol, with alpha-benzoinoxime (alpha BO) as the complexing agent for Mo(VI) and a 0.5 mol L-1 acetic acid - sodium acetate buffer as supporting electrolyte was successfully used for the determination of molybdenum in polyvitamin-polymineral tablets. Tablet samples were analyzed and the results were compared with those obtained both by graphite furnace atomic absorption and by recovery tests, with good correlations. indicating that this may be considered as an alternative procedure for routine determination of Mo(VI) in pharmaceutical samples.29115315

    Direct evidence for charge stripes in a layered cobalt oxide

    Recent experiments indicate that static stripe-like charge order is generic to the hole-doped copper oxide superconductors and competes with superconductivity. Here we show that a similar type of charge order is present in La5/3 Sr1/3 CoO4 , an insulating analogue of the copper oxide superconductors containing cobalt in place of copper. The stripe phase we have detected is accompanied by short-range, quasi-one-dimensional, antiferromagnetic order, and provides a natural explanation for the distinctive hour- glass shape of the magnetic spectrum previously observed in neutron scattering mea- surements of La2−xSrx CoO4 and many hole-doped copper oxide superconductors. The results establish a solid empirical basis for theories of the hourglass spectrum built on short-range, quasi-static, stripe correlations

    Preimplantation development regulatory pathway construction through a text-mining approach

    BACKGROUND: The integration of sequencing and gene interaction data and subsequent generation of pathways and networks contained in databases such as KEGG Pathway is essential for the comprehension of complex biological processes. We noticed the absence of a chart or pathway describing the well-studied preimplantation development stages; furthermore, not all genes involved in the process have entries in KEGG Orthology, important information for knowledge application with relation to other organisms. RESULTS: In this work we sought to develop the regulatory pathway for the preimplantation development stage using text-mining tools such as Medline Ranker and PESCADOR to reveal biointeractions among the genes involved in this process. The genes present in the resulting pathway were also used as seeds for software developed by our group called SeedServer to create clusters of homologous genes. These homologues allowed the determination of the last common ancestor for each gene and revealed that the preimplantation development pathway consists of a conserved ancient core of genes with the addition of modern elements. CONCLUSIONS: The generation of regulatory pathways through text-mining tools allows the integration of data generated by several studies for a more complete visualization of complex biological processes. Using the genes in this pathway as "seeds" for the generation of clusters of homologues, the pathway can be visualized for other organisms. The clustering of homologous genes together with determination of the ancestry leads to a better understanding of the evolution of such process
