25. CARACTERIZAÇÃO DE GENES DO VÍRUS DO ECTIMA CONTAGIOSO ENVOLVIDOS NA REGULAÇÃO DA VIA DE SINALIZAÇÃO DO NF-κB / CHARACTERIZATION OF ORF VIRUS-ENCODED GENES INVOLVED IN THE REGULATION OF THE NF-κB SIGNALING PATHWAY
Orf virus (ORFV), the type member of the genus Parapoxvirus of the family Poxviridae, is the etiologic agent of orf or contagious ecthyma, a contagious and ubiquitous disease of sheep and goats. ORFV genome consists of a double stranded DNA molecule with approximately 138 Kb, and contains 131 putative genes. Among those, 15 are novel genes, unique to parapox

26. Isolamento e caracterizaÃÃo parcial dos Genes beta-actina e miosina de cadeia pesada do CamarÃo rosa Farfantepenaeus subtilis / Isolation and partial characterization of genes beta-actin and myosin heavy chain shrimp Farfantepenaeus subtilis
The penaeid shrimp Farfantepenaeus subtilis is an important native species for fisheries industry in Brazil. Among marine shrimps of commercial importance, penaeids are recognized as a valuable resource for fishery and aquaculture in tropical and subtropical regions. However, data on these species is extremely reduced, especially concerning genetic elements

27. Estimates of DNA strand breakage in bottlenose dolphin (Tursiops truncatus) leukocytes measured with the Comet and DNA diffusion assays
The analysis of DNA damage by mean of Comet or single cell gel electrophoresis (SCGE) assay has been commonly used to assess genotoxic impact in aquatic animals being able to detect exposure to low concentrations of contaminants in a wide range of species. The aims of this work were 1) to evaluate the usefulness of the Comet to detect DNA strand breakage in

28. Genetic signatures of parental contribution in black and white populations in Brazil
Two hundred and three individuals classified as white were tested for 11 single nucleotide polymorphisms plus two insertion/deletions in their Y-chromosomes. A subset of these individuals (n = 172) was also screened for sequences in the first hypervariable segment of their mitochondrial DNA (mtDNA). In addition, complementary studies were done for 11 of the

29. Taxonomy of Tricorythopsis Traver and Tricorythodes Ulmer (Ephemeroptera: Leptohyphidae) and advancements in the molecular studies of Ephemeroptera / Taxonomia de Tricorythopsis Traver e Tricorythodes Ulmer (Ephemeroptera: Leptohyphidae) e avanços nos estudos moleculares de Ephemeroptera
In order to contribute to the taxonomy of Tricorythodes Ulmer and Tricorythopsis Traver, new taxa were described and molecular techniques were used as complementary tools in the systematic of the Ephemeroptera. As a result of the work, five new species were described, three for genus Tricorythodes (T. rondoniensis, T. sallesi and T. caunapi) and two for Tric

30. AnÃlise in silico de novos potenciais polimorfismos genÃticos de risco na DoenÃa de Alzheimer em bancos de dados de Microarrays
Genomic and Proteomic studies of neurodegenerative disorders require complementary approaches to integrate the massive amount of data generated in high throughput experimental procedures. We propose a Bioinformatics pipeline in which expression studies guide the selection of candidate genes that should be screened for potential new genetic variations from a

31. Molecular diagnostic of active human cytomegalovirus infection in patient urdergoing transplanation by nested polymerase chain reaction : comparison between peripheral blood leucocytes and serum / Diagnostico molecular da infecção ativa por citomegalovirus humano (HCMV) em pacientes submetidos a transplante pela reação em cadeia da polimerase (tipo "Nested PCR") : comparação entre leucocitos do sangue periferico e soro
The Human Cytomegalovirus (HCMV) is the main cause of post-transplant complications. Specific methods that allow to identify early patients with risk of developing disease for which treatment is indicated, have been required so that few patients are treated unnecessarily and for the effective therapeutic institution. The "Nested-PCR" has been commonly used i

32. A majority of Brazilian patients with rheumatoid arthritis HLA-DRB1 alleles carry both the HLA-DRB1 shared epitope and anti-citrunillated peptide antibodies
The objective of the present study was to evaluate the contribution of the shared epitope (SE), the rheumatoid arthritis (RA) protection model, and the occurrence of anti-cyclic citrullinated peptide (anti-CCP) antibodies in RA patients from a genetically diverse population. One hundred and forty Brazilian RA patients and 161 matched controls were typed for

33. Localization of electronic states in DNA-like double strand model / Localização eletronica em cadeias duplas : aplicação ao DNA
In this work we discuss and compare different definitions for localization of electronic states in quase-one-dimensional systems: the 1-D case of polianilines chains and DNA-like molecules. In order to establish ranges of equivalence, the localization length from both, the conductance and participation ratio, is computed. For the 1-D case the con-ductance is

34. Desenvolvimento de sensor bioletroquímico para detecção da hanseníase
Leprosy is a chronic, granulomatous and dermatological disease, from infection caused by the bacillus Mycobacterium leprae. It is object of intervention of the state, because when untreated cause disability in the economically active population. Brazil remains one of the four endemic countries responsible for 34% of all cases registered at the beginning of 2

35. Seqüências ORESTES (open reading frame expressed sequence tags) de trypanosoma cruzi e transcrição de DNA satélite / ORESTES (open reading frame expressed sequence tags) sequences of Trypanosoma cruzi and transcription of satellite DNA
In T. cruzi databases, aproximately 3.750 ESTs of amastigotes and trypomastigotes, sequenced from the 3´ or 5´ ends cDNA clones can be found in T. cruzi databases. The ORESTES (Open Reading Frame Expressed Sequence Tags) methodology generates partial transcribed sequences derived mainly from the central portions of mRNAs, favoring the discovery of new gene

36. Caracterização funcional de componentes da resposta ao dano DNA em Aspergillus nidulans: os genes chkA, chkB e ddbA / Functional Characterization of DNA damage response components in Aspergillus nidulans: the ddbA, chkA and chkB genes.
The constant exposure of different organisms to agents that damage the DNA structure, has provided the cells with repair mechanisms that are conserved during evolution. In mammal cells, the DNA damage repair pathways and the cell cycle checkpoint regulation act together to prevent cell cycle progression before the repair is performed avoiding mutation fixaxi
