25. Evolução tecnologica dos exames de paternidade e sua validade juridica / Technological evolution of the exams of paternity and its juridical validity
The science and the technology come if constantly surpassing and its progresses rebound in the deliberations of the Judiciary Power. Decisions on paternity set in techniques, now supplanted by the progress of the science, they have been questioned judicially, placing in evidence the activity of the judicial expert. In that context, the present research work

26. Modelagem de um ambiente para análise de DNA em genética forense
Os avanços da biologia molecular vêm favorecendo a geração de uma enorme quantidade de informações genéticas em um tempo cada vez menor. Essa capacidade de geração de dados permite que os pesquisadores acelerem o ritmo de suas pesquisas, exigindo a utilização de ferramentas eficientes para o gerenciamento desses dados. Outra necessidade está rela

27. "Estudo de freqüências alélicas e 12 microssatélites do cromossomo Y na população brasileira de Araraquara e da região da grande São Paulo" / Allelic frequency study of 12 Y microsatellite in the brazilian population of Araraquara and Grande São Paulo
Este trabalho tem como objetivo a determinação da freqüência alélica de 12 microssatélites do cromossomo Y na população de Araraquara e da Grande São Paulo, tendo em vista a necessidade de ampliação dos dados referentes a estes marcadores devido a sua crescente aplicação em diferentes áreas, entre elas a forense na qual a utilização destes mi

28. Desempenho forense de microssatÃlites para a investigaÃÃo da origem de Cannabis sativa no Brasil e no Paraguai
The black market of Cannabis sativa (marijuana) in Brazil is basically supplied by illegal plantations from Paraguay, North and Northeastern Brazil. Without a well established intelligence service is difficult to state the right origin of large and small apprehensions. Any new technology that helps this task will be of inestimable value for the war against t

29. DNA exam application in crime elucidation / Aplicação do exame de DNA na elucidação de crimes
The wide application of the DNA exam in paternity investigation led to the massive divulgation of its efficiency through the communication channels, earning it a reputation of infallible result, and jeopardizing the credit of older analytical methods. While focused by the media as the most supreme technique, several limitations were omitted regarding its use

30. DNA extraction of human teeth submitted to high temperatures: evaluation of three methods . / "Avaliação de três métodos de extração de DNA de dentes humanos submetidos ao calor"
Biological remains of carbonized human bodies are usually not possible to use in forensic analysis. In these cases, teeth are usually selected since enamel, dentin and cement provides protection to the genetic material. The present study evaluates DNA extracted using three methods (organic, isopropilic alcohol and silica) of teeth submitted to different temp

31. Análise de DNA em osso humano: estudo qualitativo da microestrutura do osso compacto / Analysis of human DNA bone: qualitative study of compact bone microstructure.
Para a execução da etapa inicial da identificação médico-legal de restos humanos (antropometria e exame dos arcos dentários), faz-se necessária uma limpeza prévia da ossada, para a remoção de tecidos moles putrefeitos. Os casos não identificados por esses métodos tradicionais, poderão ser submetidos ao exame de DNA. No entanto, apesar do grande

32. Characterization of new Schistosoma mansoni microsatellite loci in sequences obtained from public DNA databases and microsatellite enriched genomic libraries
In the last decade microsatellites have become one of the most useful genetic markers used in a large number of organisms due to their abundance and high level of polymorphism. Microsatellites have been used for individual identification, paternity tests, forensic studies and population genetics. Data on microsatellite abundance comes preferentially from mic

33. Procedimentos de biossegurança em laboratorio de DNA forense
A review of the norms and technical precautions referring to the bio-safety in forensic DNA research laboratories was made in the present study. The laboratory for extracting, analyzing and digesting the DNA is a place of constant learning and risks for the teams who work there. Knowing such risks is the most efficient way to avoid them and that is a necessi

34. Fixed bin frequency distribution for the VNTR Loci D2S44, D4S139, D5S110, and D8S358 in a population sample from Minas Gerais, Brazil
Fixed bin frequencies for the VNTR loci D2S44, D4S139, D5S110, and D8S358 were determined in a Minas Gerais population sample. The data were generated by RFLP analysis of HaeIII-digested genomic DNA and chemiluminescent detection. The four VNTR loci have met Hardy-Weinberg equilibrium, and there was no association of alleles among VNTR loci. The frequency da

35. Identification and characterization of polymorphisms at the HSA alpha1-acid glycoprotein (ORM*) gene locus in Caucasians
Human alpha1-acid glycoprotein (AGP) or orosomucoid (ORM) is a major acute phase protein that is thought to play a crucial role in maintaining homeostasis. Human AGP is the product of a cluster of at least two adjacent genes located on HSA chromosome 9. Using a range of restriction endonucleases we have investigated DNA variation at the locus encoding the AG

36. Diversidade genética e desempenho forense da análise de haplótipos de locos microssatélites no cromossomo Y em populações brasileiras.
DNA polymorphisms on the human Y chromosome have increasingly been used for evolutionary studies and individual identification. Y chromosome STRs show moderate levels of polymorphism and typically spiky allele frequency distributions when compared to autossomal STRs. The patrilineal inheritance of the non recombining portion of the Y chromosome results in th
