Resposta imune à saliva de flebotomíneos (diptera: psychodidae) em indivíduos residentes em áreas urbana e periurbana no nordeste do brasil

Visceral leishmaniasis (VL) has a wide geographical distribution in tropical and subtropical areas of the planet, which is a protozoan parasite of the genus Leishmania. This pathogen is transmitted to the host through the sandflies bite, with its saliva, the immune response that leads to both. In the state of Rio Grande do Norte, 85% of the sand flies captured is Lutzomyia longipalpis, but the second most abundant, Lutzomyia evandroi, it deserves emphasis because its wide distribution and eclectic behavior. The exposure of people living in endemic areas for the insect vector VL greatly increases the chances of infection. This study aimed to evaluate aspects of the epidemiological profile of VL in endemic areas of human and nonendemic in the metropolitan area of Natal, as well as verify the abundance and seasonal fluctuations of sandflies species in two counties endemic for VL. Were collected in the municipalities of Nísia Floresta, Parnamirim, São Gonçalo do Amarante and Macaíba, of which groups of females were separated for further dissection of the salivary glands and identification of species. The blood samples used were from individuals of two Natal s districts where it has never been reported cases of VL and neighborhoods of Parnamirim applicants who present cases of VL. In the municipality of Nísia Floresta, the most abundant species was L. evandroi with 38.39%, followed by L. longipalpis with 36.22%, L. walkeri 19.67% L. lenti 3.81%, L. wellcomei 1.39% and L. whitmani 0.52%. Already in Parnamirim the proportions were L. walkeri with 73.15%, L. evandroi with 10.55%, L. wellcomei 7.63%, L. longipalpis 6.37%, L. whitmani 1.46%, L. sordellii 0.52%, L. intermedia 0.21 and L. shanonni 0.1%. In both municipalities was observed higher abundance of species distributed in the initial months of the year, as February and March. The study showed that no difference in exposure to the vector of VL among individuals from endemic and non endemic area for this disease. But there are differences in exposure between individuals of L. longipalpis and L. evandroi, confirming the great powers of the first vector. It was also characterized as predominant phenotype in the population of endemic areas who had negative serologic responses to antigens of Leishmania and result in negative Montenegro skin test (DTH), indicating that much of the population hasn t been bitten by infected insects

Análise do estado da arte dos aspectos diagnóticos, periciais e jurisprudenciais das LER/DORT no contexto previdenciário das doenças do trabalho no Brasil

Objetivo: analisar o estado da arte dos aspectos diagnósticos, periciais e jurisprudenciais das LER/DORT (Lesões por Esforços Repetitivos / Distúrbios Osteomusculares Relacionados ao Trabalho) no Brasil. Materiais e Método: trata-se de pesquisa descritiva, de natureza qualitativa, com formato documental, utilizando-se a técnica de análise de conteúdo. A avaliação evolutiva da legislação previdenciária relacionada as LER/DORT foi realizada através da pesquisa no banco de dados disponibilizado pelo Governo Federal e mediante a consulta ao DATAPREV/Sislex. A avaliação dos aspectos diagnósticos foi instrumentalizada através, principalmente, de artigos científicos publicados entre 2003 e 2008, nas línguas portuguesa, inglesa, espanhola e francesa, relacionados com os métodos de diagnósticos complementares das LER-DORT (ressonância magnética, tomografia computadorizada, ultrassonografia e eletroneuromiografia). As jurisprudências foram obtidas através da busca dos julgados sobre o tema, entre 2003 e 2008, pertencentes ao Supremo Tribunal Federal, Superior Tribunal de Justiça, Tribunais Regionais Federais, Tribunal Superior do Trabalho e Tribunais Regionais do Trabalho. Resultados: foram identificados 48 artigos abordando os aspectos diagnósticos das LER-DORT, observando-se que os exames por ressonância magnética, ultrassonografia e eletromiografia demonstraram ser mais efetivos, dentro das suas especificidades, para a complementação do exame clínico de patologias relacionadas às LER-DORT. A análise das 123 jurisprudências selecionadas demonstrou, de forma geral, que as LER-DORT equiparam-se ao acidente de trabalho, devendo apresentar nexo de causalidade (atestado através de laudo médico-pericial) e, ainda, ensejam a ação por danos morais, a qual, devido à EC nº 45 passou a ser competência da Justiça do Trabalho. O Estado da arte dos aspectos periciais encontra-se representado pela vigência da Instrução Normativa n. 98/2003, a qual traz como aspecto fundamental a determinação de novos parâmetros a serem considerados na definição de um quadro de LER-DORT, dispondo, ainda, sobre a conduta ética que deve ser adotada pelo médico perito, bem como chama a atenção para a necessidade dessas doenças do trabalho serem comunicadas às autoridadades competentes, através da emissão da Comunicação de Acidente de Trabalho (CAT). Conclusão: as LER-DORT representam, hoje, um problema de importante impacto, não apenas previdenciário, mas também econômico em diversos países, nos quais o Brasil encontra-se inserido. Estudos sobre o estado da arte relacionados às LER-DORT são fundamentais para auxiliar na construção de um modelo crítico e consciente que colabore com a garantia de sustentabilidade do sistema previdenciário no Brasil

Os instrumentos de incentivo à produção e uso de biodiesel no Brasil: uma análise constitucional sob o princípio do desenvolvimento sustentável

The recent insertion of biodiesel derived from oily vegetables in the Brazilian energetic matrix calls for the study of some aspects that belong to it. The analysis of the carbonized energetic pattern concerns the paradigm of economic development that is constitutionally enshrined sustainable development which make environmental protection compatible with the needs of the economic rationality. This text is structured according to the ideas of modern hermeneutic that sees substantial value in the principles capable of create a harmonious relationship between law and society. The study of the constitutional principles to conduct a legal analysis about the National Program for Production and Use of Biodiesel - PNPB. The aim of the research is the study of PNPB ahead with the constitutional principles governing the economic order. To achieve this end we studied the sustainable development as a constitutional principle. We start with the notion that the thematic principles, and fundamental to understanding the dimension of sustainable development institute, since its concept is closely related to the applications of the principles enshrined in virtually all the constitutional order of the Western world. Then this was the National Energy Policy, initiating the approach by guiding principles of the National Energy Policy to develop the theme of public policy in the energy sector. Therefore, we studied the National Program of Biodiesel Production and Use - PNPB. From a technical introduction to the concept of biodiesel and a brief historical background, analyzing their advantages compared to fossil fuels predominantly used. Then it became a regulatory overview of the Brazilian legislation on the subject, central to understanding the plans and objectives pursued by the Brazilian government with encouraging the production of biodiesel. Finally discussed the tax incentives for production and use of biodiesel in Brazil. From the idea of federalism, characterized the tax as an instrument of state intervention in the economy. And finally it brought the tax incentives of Law No. 11.116/2005 in the face of the constitutional principles of economy and tax, and tax incentives from projects related to the Kyoto Protocol

Os conflitos de competência normativa do estado regulador brasileiro no setor administrado pela ANP

The dissertation has by objective describe the administrative activity of regulation exercised by independent regulatory agencies, observing that this activity was already done before this structures creation, however, after a really deep administrative reform that had as objective built a Public Administration with more efficiency, it passed to be done with some own peculiarities of these new structures of regulation. The work gave especial attention to what concern the conflicts of normative competency that really often happen between ANP (Agência Nacional do Petróleo, Gás Natural e Biocombustíveis) and the legislatives organs of the Republic Federative of Brazil, because energetic area has unbelievable mater to any country, and the fact of some juridical norm be against the law and be accepted is very dangerous, it affronts the constitutional principle of the legality e may put in risk the democratic Estate of law, them, regulatory dogmatic must be scientifically knows, and developed, thought and especially there are so many doctrinaires divergences about regulation constitutionality. As a theorist point, the investigation got the Logical nocontradiction principle, according Hans Kelsen and Lourival Vilanova thought, doing a philosophical reflection about the system of positive law, in which there are many antinomies, or conflicts of norms, what include the conflicts of the administrative acts expedited by ANP and the legislation of the brazilian regulatory Estate. For a better understanding and exemplify some perplexities treated by the doctrinaire angle, this work did a lucubration about a possibility of a normative conflict between a ANP resolution and the municipal legislation in a specific case, also, brought several jurisprudences for the brazilians courts of justice, that confirm the empiric existence of normative conflicts among ANP s administrative norms and federal legislation. Finally, concludes observing that the regulation is not a legislative competency delegation to regulatory agencies, is just a new exercise of the administrative function, it is a technical specialization of the public administration, that using this know-how can acting with more efficiency, however the normative power of regulatory agencies must respect the empire of law, so in this terms, the dissertation suggests the ponderation of the constitutionals principles of efficiency and legality how form to harmonizing the democratic legitimate inherent to legal norm supremacy, with the perspective of an efficient economic and institutional development

A concretização do princípio da igualdade em matéria tributária por meio de sentenças aditivas

This work aims to study the additive decisions, a type of juridical interpretation developed in foreign legal systems and which are known in Italy as adittive sentences. Thefore, this dissertation is based on theorical studies developed around the subject in Italy and Brazil. Considering the fact that the fundamental rights face a problem of implementation, being decreased its normative force when there are legislative partial omissions lacking constitutional justification creating privileges to certain individuals or social/economical groups over others, the method of additive interpretation according to the Constitution can be used in order to realize the principle of equality. In tax matters the subject is even more relevant in the way that it represents an important role in the economy. Partial legislative omissions can generate inequalities, favoring certain taxpayers in relation to others in similar legal situation. In these cases the privilege may have a negative impact on economic order restricting values related to the basis of market competition. On those occasions, Brazilian Judges and Courts must exercise their constitutional jurisdiction in order to expand the effects of the legislative omissions, based on the principle of equality by extending the standard to equal tax situations in order to maintain neutrality in taxation

A Constituição Federal de 1988 e a integração regional : o desafio da harmonização tributária

As an effect of the growing interdependence in international relations, regional integration was conceived to face globalization, with a remarkable influence in politics and law, since the first steps of the European experience. In Latin America, regional integration ideas have blossomed in the 60 s. Among its experiences, MERCOSUL is the one with the most advanced objectives. However, MERCOSUL has not managed to achieve the objectives planned nor moved forward the integration process. Differently of what happened in Europe, in MERCOSUL the common market projected is concluded. It faced many disappointments throughout its brief history. As it matters to law, those were caused by the absence of supranationality, a mechanism that would allow MERCOSUL s decisions to be directly binding in the States with no need of bureaucratic proceedings to incorporate them to national legal systems. Among Latin American States, Brazil is probably the most resistant to integration process, due to Federal Constitution 1988 rigidity and legal professionals conservadorism towards opening legal system to international law. In Brazil hermeneutical standards are always based on national sovereignty and international law is referred as less important. The problems become more visible relating to taxation, a subject that plays an enormous role in integration process for its economic impact, demanding the execution of tax harmonization policies compatible to the integration levels aspired. However, because of the large number of tax rules in the Federal Constitution, structural changes initiatives face difficulties in order to be implemented. Actually, after two Constitutional Reforms on taxation, Brazil has not yet succeeded on promoting the necessary adaptations to regional integration. The research has confirmed the hypothesis that supranationality has indispensably to be adopted if Brazil really desires to move forward the integration process. But it has also been demonstrated that there are hermeneutical paths suitable to the constitutional profile which allow the adoption of supranationality, through the revision of the sovereignty traditional concept

Compromisso social do psicólogo em artigos publicados em periódicos científicos no Brasil

Psychologist s social commitment in scientific articles published in scientific papers in Brazil. A situation analysis of the scientific production concerning psychologist s social commitment can aid the historical constitution of this theme and also subsidize reflections about the course of this profession in Brazil. In order to contribute to this debate, the theme social commitment of psychologist was analyzed in the scientific literature concerning psychologist profession in the country. Specifically, papers about the profession that mentioned the theme social commitment were characterized and their approach of this matter was analyzed. In order to accomplish these goals, two research stages were fulfilled: first, in a systematic search for scientific literature in internet databases, studies about the psychologist profession in the country were gathered; in the second stage, scientific papers relating to social commitment in their titles, abstracts or keywords were selected. 61 papers were retrieved, organized in electronic database and full-text analyzed, based in two axis: scientometric and thematic. The papers were identified, in general, as recent, of theoretic character and aligned with several Psychology subareas; mainly produced in public universities, in country s southwest; were of conjunctural interest to the authors research projects, individually published, by professors in touch with post-graduation; published in open access journals, with high Qualis evaluation. It was verified that there is no consensus on the meaning of the theme, prevailing definitions concerning the understanding of the social reality, to the majority of people or to a progressive-aligned professional performance. Are adduced as committed agents: the psychologist (sometimes together with other kinds of professionals or with users), the academia, and the representative entities of the profession. Depending on the subareas and the nature of study, all papers mentioned at least one of the following criteria: expansion of target-audience, renewal of practices, political direction, defined theoretical approach or adequate technical competence, sometimes relating each other. In short, psychologist s social commitment is a contradictory issue which have earned projection in scientific literature, reiterating the historical custom of evaluate the psychologist profession. As conclusion, it is regarded as indispensable to intensify the reflection about the role whose psychologist plays in a class-cleaved society and the limits and potentials of his performing in that framework.

Isótopos de Nd na proveniência de rochas e sedimentos da bacia potiguar, ne do Brasil

Nd ISOTOPES IN THE PROVENANCE OF TERRIGENOUS AND CARBONATE ROCKS AND SEDIMENTS OF THE POTIGUAR BASIN, NORTHEASTERN BRAZIL. Mesozoic and Cenozoic rocks from the Potiguar Basin, including terrigenous and carbonate sediments have been investigated to identify their isotopic signature and source areas. Additionally, this study aims to determine the provenance of terrigenous and carbonate sediments on the Brazilian Continental shelf adjacent to Potiguar Basin. The Sm-Nd isotopic signatures of the rocks yielded model ages (TDM) in the range of 2,19- 2,88 Ga, indicating archean to paleoproterozoic sources from the basement. The terrigenous sediments yielded model ages (TDM) in the range of 2,31-2,26 Ga, from 17,5 to 0 cm depth. Despite the small number of samples, limited variations of provenance ages indicates the homogenization of the sediments, probably due to the strong influence of the basement, as the main source of sediments to the shelf. The Sm-Nd isotopic signatures of the carbonate sediments yielded model ages (TDM) in the range of 2,09-2,61 Ga, indicating archean to paleoproterozoic sources from the basement. The results also indicate that the shelf sediments are mainly derived from the Açu River or other small rivers from the Setentrional Sector of Rio Grande do Norte State. The littoral drift doesn´t seem to contribute with sediments from the Oriental Sector since isotopic signatures from this sector were not detected.

Direitos fundamentais sociais no Brasil: desafios e mecanismos para sua concretização

The work referred to above, in order to contribute to the legal issues, economic, political and social of the violation of social rights, performs even firmer approach to various implementation mechanisms of social rights in Brazil. Therefore, it begins the study dealing with aspects and important characters of the rights under discussion, as its normative forecast, concept, classifications; respect of social rights with the existential minimum; the principle of reservation of the possible and the need to use this principle as optimization commandment of state resources and the deficit of the realization of social rights in the country. This, in later chapters, in an interdisciplinary approach, challenges and proposals for the realization of social rights by bringing in each chapter, mechanisms for such implementation. That way, as a general objective, it has been to contribute to the discussed problems, when present proposals for the realization of social rights in the Brazilian context. As specific objectives, as well as record the key aspects of the rights in allusion, the one has to promote the perspective of economic development and taxation as posts instruments that the State must be focused on the promotion of social rights by registering in this context that nonexistent economic development without reducing poverty, misery and social inequality and adding that there should be a directly proportional relationship between the tax burden in the country and the human and social development index; analyze the achievement of budget control as essential and healthy measure for the realization of social rights; highlight the importance of society to the achievement of unavailable social interests, affirming the need for the implementation of participatory democracy and, in this line, brings knowledge of the Constitution and the constitutional sense as elements that provide the constitutional progress. Finally, it presents a study on public policies, considering that these are equivalent to the primary means of the promotion of social rights. That way it analyzes the stages that integrate public policies, ranging from the perception of social problems for evaluation and control of the policies implemented; debate about the administrative discretion in when it comes to public policies; brings the classification of essential public policies, the relationship of these with the existential minimum, control parameters and, finally, the legalization of public policy, regarded as legitimate to remedy the unconstitutional state failure and give normative effectiveness and strength to the defining constitutional rules for fundamental social rights. It uses to achieve the objectives outlined, the bibliographic and normative approach method and performs an analysis of jurisprudence related understandings to matter. In the conclusions, it rescues the most important aspects elucidated at work, with the aim of giving emphasis to the proposals and mechanisms that contribute to the solution of the discussed problems.

A competência leitora de alunos do ensino fundamental: uma proposta de intervenção

Reading is a activity of paramount importance in the life of every human being, since this practice is essential condition for the exercise of citizenship. Therefore, it is through reading that the student has access to the knowledge that part of the world around him. However, given the complexity involved in the process of learning to read, teach students to read is not an easy task because often they do not acquire the skills necessary to understand the texts. According to this view, the present study focuses on an educational intervention who aim at contribut to the development of reading competence of students in 6th grade "U" of the State School Senador José Bernardo, in São João do Sabugi - RN. The activities which were of that intervention process were conducted in Portuguese Language classroom and developed through didactic sequences drawn from reading strategies, based on the genres tale and news, since students had serious problems with regard to reading comprehension. Given the importance of meeting the aforementioned difficulty, we seek to develop a proposal for interactive reading activities through genres as a language of social practices, whose goal aimed read to understand and make sense of texts. This intervention proposal falls under the Applied Linguistics and to perform it, were taken as a basis some theories focused on the notion of language as sociointerativa practice, such as studies of Bakhtin (2006, 2011), Bronckart (2012) and targeted contributions to the teaching of reading activity, including, Solé (1998), Oliveira (2010), Kleiman (2013), Leffa (1996, 1999), Silveira (2005). Discussions about genres followed the studies of Bakhtin (2011), Marcuschi (2008), as well as other theoretical; the didactic sequences were constructed from Bronckart (2012), Dolz; Noverraz; Schneuwly (2013) and, with regard to the teaching of Portuguese Language, the guidelines were adopted contained in PCN / LP (1998), as well as in Antunes (2003, 2009) and other authors. The results showed that students in the 6th grade increased their understanding capacity of the read texts, by implementing the didactic and pedagogical actions, thereby acquiring the reading competence they needed to keep learning.

A relação entre memória de trabalho e competência leitora em crianças em risco de transtorno de aprendizagem do Projeto Acerta: um estudo exploratório

Reading and writing are essential rights, which involve individual and social aspects; in addition, these skills are important when it comes to socio economic and political development, critical thinking and an active participation in society (UNESCO 2005). From a neurobiological standpoint, our brain is not prepared for reading, and this practice must be deliberately acquired via instructional guidance (DEHAENE 2009). However, reading disorders and deficits within executive functions, such as low working memory capacity, can make reading arduous. The aim of this study is to investigate the development of reading skills within 45 third grade students from public schools in the city of Natal – RN and its connection to working memory capacity, through information gathered from the Provinha Brasil, data generated from working memory tasks (Portuguese version of AWMA - Automated Working Memory Assessment) and fluid intelligence measures RAVEN. Based on this main objective, we attempted to answer the following research questions: (a) What are the correlations between working memory and reading scores?; (b) What characterizes the relationship between working memory capacity and the risk of reading disabilities amongst the participants in this study?; Following a quantitative research methodology, the Provinhas Brasil from 3rd grade students belonging to the six public schools members of Project ACERTA - Avaliação de Crianças em Risco de Transtornos de Aprendizagem (CAPES/OBEDUC)- were analyzed and compared to the scores from the working memory tests and the fluid intelligence ones. Results indicate that reading skills within children at risk of reading disabilities are directly linked to working memory capacity, especially with regards to the phonological component. It is also evident that the participants with less working memory capacity show more difficulties in the reading abilities that demand interpretation skills. Thus, we intend to contribute to the discussion regarding the diagnosis of reading disabilities and possible intervention strategies.

Da arenga ao debate: o aprimoramento da competência argumentativa por estudantes do ensino médio

In order to understand the factors involved in the improvement process of argumentative competence by students of 2nd year of high school, we undertook a qualitative approach research and interventional nature, during which we adopted the conduct of participant observation in a school belonging to the state schools of Rio Grande do Norte, located on the outskirts of the city of Natal. The analyzed corpus consisted in the interim intervention and entails the answers to a semi-structured questionnaire, fourteen opinion articles and three regrados debates, produced by the students, in addition to video recordings of ten sessions and personal notes pertaining to another six, totaling sixteen sessions observed during the school year 2014. As the most important bibliographical references we study skills and reasoning from the perspective of discursive social interactionism. Analyzing the data we loan the principle of categorization, opting for critical-descriptive presentation and were revealed to us, via the classified evidences, that among the factors involved in the study process, it appears with more relevance to set up an effective intellectual community, which meets in constant interaction subjects, which alternate assuming the conditions of speakers and audience. The constitution of this community depends largely on the teaching mediation and is indispensable to the (re)design of the studied competence, in interactions with her the subjects afforded learn and develop their competence, reshaping the limits of their zone of proximal development.
