Pesquisa de genes de resistência do M. tuberculosis a isoniazida e rifampicina por sequenciamento e pela tecnologia de DNA-STRIP

Tuberculose (TB), causada por Mycobacterium tuberculosis, é uma das doenças infecciosas que mais causam mortes. Estima-se que mais de dois bilhões de pessoas estejam infectadas no mundo. O tratamento da TB consite em associação de fármacos, isoniazida, rifampicina, pirazinamida e etambutol, nos primeiros 2 meses e 4 meses de isoniazida e de rifampicina. Internacionalmente, são consideradas cepas multi resistentes (MDR), as que apresentam resistência simultânea a isoniazida e a rifampicina. A rápida detecção de resistência é essencial para o controle e tratamento da TB, reduzindo, assim, o custo do tratamento e a transmissão da doença. Neste projeto, os isolados já identificados fenotipicamente como resistentes a isoniazida e/ou rifampicina, foram submetidos ao sequenciamento de Sanger para pesquisa de 3 genes relacionados a resistência a isoniazida (katG, inhA e ahpC) e 1 gene de resistência a rifampicina (rpoB). Foi realizada uma comparação destes genes mutados para a resistência utilizando o novo teste desenvolvido pela Biomérieux, denominado GenoType® MTBDRplus, que se baseia na tecnologia DNA-STRIP. Através deste novo teste, foi observada mutação em 22 isolados clínicos de M. tuberculosis para genes de resistência a isoniazida e/ou rifampicina, sendo 4 provenientes do MS e 18 de SP. Já pelo sequenciamento genético foi observada mutação em 24 isolados para genes de resistência a isoniazida e/ou rifampicina, sendo 6 provenientes do MS e 18 de SP. Portanto, através do sequenciamento de Sanger, foi possível detectar um número maior de isolados mutados e mais mutações quando comparado ao teste GenoType® MTBDRplus. Isso acontece porque na técnica de sequenciamento, um fragmento do gene como um todo é analisado e no caso do teste GenoType® MTBDRplus, é verificada apenas a ausência ou presença das mutações mais frequentes descritas na literatura, além de não ser analisado o gene ahpC. A grande ...

Análise da recepção de um programa de transformação de cultura organizacional em uma empresa de tecnologia

The Organizational Culture has been in the spotlight in the last 25 years, studies show the influence of the culture in the production processes and in the strategy decisions of the companies. Changes in the organizational culture is necessary in key-moments of the corporation and this transformation moment influences directly the personal life and the professional life of the employees. The objective of this monograph is to verify the application of the “Transformation Program”, which is the changing program of a technology enterprise, and to attest the acceptation degree and the knowledge of the employees about the program, as well the main difficulties found by the company while implementing the project. Using a quantitative pool, the acceptation degree, the knowledge of the employees and their engagement with the Transformation Program were analyzed by checking the favorability of the answers and comparing the percentage of the whole company and its locations, besides with the results an understanding change curve was created, it identifies the stage that he employees are during the changing process. An interview with the actual and the previous program officers and two project managers was done, in order to identify their alignment with the theory and their perception about the difficulties found while applying the program. It was noted that the employees have heard about the Transformation Program and the majority is in the exploration phase of the understanding change curve, although it is necessary an special attention with the leaders, because the researches showed that the leaders are acting like a bottleneck in the communications by keeping the information that should be shared

As políticas de ciência e tecnologia no Brasil: um estudo de seus desdobramentos para o desenvolvimento através da formação de mão-de-obra especializada

O presente trabalho discute a evolução histórica das políticas de ciência e tecnologia (C&T) no Brasil e seus desdobramentos para o desenvolvimento do país. É sabido que a C&T pode estimular o crescimento econômico, o investimento e a competitividade de um país. Nesse sentido, a inovação também se torna importante para as políticas de C&T. Além disso, o nível de pesquisa e desenvolvimento (P&D) acaba sendo estimulado, permitindo que haja dinamismo tecnológico e absorção de avanços – que são gerados em outros países – no país. No caso brasileiro, a C&T começou a se desenvolver ainda na época da ditadura (fim da década de 60), mas pode-se dizer que ela começou a ter uma importância realmente evidente a partir da década de 90 e, em particular, durante o governo Lula (2003-2010). Entende-se também que recursos humanos com alta qualificação constituem um contingente fundamental para o desenvolvimento econômico e social do país, sendo decisivo para a difusão e a criação de novos produtos e processos. É a partir destas idéias, que o trabalho discute a forma como as políticas de C&T voltadas para a formação de mãode- obra especializada podem ajudar no processo de desenvolvimento do país através, entre outros, de um maior esforço em P&D, de projetos cooperativos que unem as universidades e empresas e, conseqüentemente, através da promoção de inovações

Arquitetura Orientada a Serviços baseada na Tecnologia Jini: um caso de teste em Computação Ubíqua

T he people’s daily lives are surrounded by computing devices, with increasing resources (sensors) and, with increasing processing. How these devices communicate is still not natural and This retards the growth of Ubiquitous Computing. This paper presents a way in which these devices can communicate using Jini technology and concepts of Service Oriented Architecture, applying these concepts in a test case of Ubiquitous Computing. To conduct the test case was constructed a fictitious system for management of a soccer championship, where users can interact with each other and with the system in a simplified way, have access to data in real time of the championship during the event. This communication is performed by services built using Jini technology, which were based on key SOA concepts, such as modularity and reusability

A tecnologia de microarray no estudo do câncer de cabeça e pescoço

(Microarray technology in study of head neck cancer). The microarray technology is a tool for global analysis of gene expression that allows investigating hundreds or thousands of genes in a sample using a hybridization reaction. This technology is based on hybridization between labeled targets derived from biological samples and an array of many DNA probes immobilized on a solid matrix, representing the genes of interest. The simultaneous study of hundreds of genes became the microarray technique a very important tool of global analysis, with applications in several areas, including the study of the development of cancer. Head and neck squamous cell carcinoma (HNSCC) is the fifth most common cancer worldwide, with a global annual incidence of 780,000 new cases. Large-scale studies involving microarrays have identified specific gene expression signatures associated with expression changes in HNSCC samples compared to normal tissue, as well as genes involved in clinical outcome and metastasis. However, the considerable heterogeneity among these studies occurs due to experimental design, number of samples, disease sites and stage, choice of microarray platform and results validation. Thus, there is much to be validated, before the technique has clinical utility. In relation to head and neck neoplasia, the large-scale gene analysis is very important, since the clinical and histopathological methods currently used appear to be insufficient to predict clinical progression and response to treatment. Thus, this approach could result in more effective diagnostic and prognostic and most appropriate therapy for this neoplasia.
