1. Impact of a chromosome X STR Decaplex in deficiency paternity cases
Deficiency paternity cases, characterized by the absence of the alleged father, are a challenge for forensic genetics. Here we present four cases with a female child and a deceased alleged father in which the analysis of a set of 21 or 22 autosomal STRs (AS STRs) produced results within a range of doubt when genotyping relatives of the alleged father. Aiming

2. Utilização de sistema multiplex de marcadores do tipo INDELs em identificação humana por DNA / Use of multiplex system with INDELs markers in human identification by DNA
Os INDELs são polimorfismos de comprimento, gerados a partir de inserções e/ou deleções de um ou mais nucleotídeos. Os marcadores INDELs, que estão amplamente distribuídos pelo genoma e se caracterizam pela alta estabilidade devido à baixa taxa mutacional (10-9), podem ser analisados a partir da amplificação por PCR (Reação em Cadeia da Polimera

3. Single nucleotide polymorphisms from cytochrome b gene as a useful protocol in forensic genetics against the illegal hunting of manatees: Trichechus manatus, Trichechus inunguis, Trichechus senegalensis, and Dugong dugon (Eutheria: Sirenia)
The identification of mitochondrial DNA polymorphisms is one of the most efficient methods for species differentiation. Genotyping of molecular markers using PCR/RFLP is a reliable, sensitive and inexpensive method for the detection of species specific mutations. The major causes of decline in Sirenia populations are accidental and intentional catches, colli

4. Emprego de miniSTRs \"non-CODIS\" em amostras biológicas de DNA forense. / The use of \"non-CODIS\" miniSTRS in forensic DNA biological samples.
Foram analisadas 80 amostras de casos forenses criminais do Laboratório de DNA do Instituto de Criminalística de São Paulo. O DNA foi extraído de materiais cadavéricos, vestígios de crimes sexuais e de locais de crimes. A quantificação se deu por PCR em tempo real e a amplificação por PCR, em 2 reações triplex, dos miniSTRs non-CODIS D10S1248, D1

5. THÊMIS: um sistema para análise forense de DNA utilizando Redes Baysianas. / THÊMIS: a software for DNA forensic analysis using Bayesian Networks.
Since the mid 80, DNA fingerprinting has revolutionized forensic science, providing a powerful tool for research, currently being widely used in studies of paternity. Laboratories that work with forensic analysis of DNA carry increasing amounts of such studies and encourage the use of software systems that help with this type of analysis. One of the requirem

6. Viabilidade da utilização de amostras biologicas obtidas de dentes humanos para obtenção de perfis geneticos de DNA / Viability of the acquirement of genetic DNA profiles using human teeth
Several factors related to how and where human teeth are found in forensic cases still a challenge to obtain genetic DNA profiles, as using theses elements as source for genetic material. This study aimed to compare the DNA extraction done through blood stains in FTA® paper cards, used as control group, and compare the mapped alleles from these to ones extr

7. Isolamento e caracterização de locos de microssatélite para Neothraupis fasciata, (Emberizidae, Passeriformes, Aves),
Microsatellite molecular markers are small repeated sequences in tanden compound of 1 to 6 nucleotides. Widely used as genetic markers, the microsatellites have a particular attribute that is the high rates of mutation. These molecular markers or are widely used in conservation genetics, population genetics, forensic research, diagnosis of diseases, ecologic

8. 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

9. 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

10. 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

11. 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

12. Inferring identify from DNA profile evidence.
The controversy over the interpretation of DNA profile evidence in forensic identification can be attributed in part to confusion over the mode(s) of statistical inference appropriate to this setting. Although there has been substantial discussion in the literature of, for example, the role of population genetics issues, few authors have made explicit the in
