1. Investigating ego modules and pathways in osteosarcoma by integrating the EgoNet algorithm and pathway analysis
Osteosarcoma (OS) is the most common primary bone malignancy, but current therapies are far from effective for all patients. A better understanding of the pathological mechanism of OS may help to achieve new treatments for this tumor. Hence, the objective of this study was to investigate ego modules and pathways in OS utilizing EgoNet algorithm and pathway-r

2. Um algoritmo para estimar a dimensão do segundo grupo de homologia de um grupo finitamente apresentado / An Algorithm for low Dimensional Group Homology
O trabalho tem por objetivo principal estabelecer uma cota superior para a dimensão do segundo grupo de homologia de um grupo G, com coeficientes em um corpo k de característica p, H2(G;k), usando o sistema operacional GAP. Será apresentado uma gama de exemplos, onde em alguns casos, calcularemos exatamente a dimensão e em outras somente uma cota superio

3. Análise estrutural do domínio de reconhecimento a carboidratos da lectina Dvirl de Dioclea virgata e sua correlação na indução da produção de óxido nítrico / Structural analysis of the carbohydrate recognition domain the DvirL lectin from Dioclea virgata and its correlation in the induction of nitric oxide production
Lectins are defined as proteins or glycoproteins of nonimmune origin that have at least one site of reversible binding to carbohydrates or glycoconjugates. Lectins of plant origin are the most studied and characterized as three-dimensional structure and biological functions related. Lectins can be found in different parts of the plant from its root to the in

4. In silico identification of coffee genome expressed sequences potentially associated with resistance to diseases.
Sequences potentially associated with coffee resistance to diseases were identified by in silico analyses using the database of the Brazilian Coffee Genome Project (BCGP). Keywords corresponding to plant resistance mechanisms to pathogens identified in the literature were used as baits for data mining. Expressed sequence tags (ESTs) related to each of these

6. A espectrometria de massas e as bio-moleculas : relação estrutura/reatividade de peptideos por reações ion/molecula e mobilidade de ions e busca de novos biomarcadores em clinica medica por imageamento quimio-seletivo de tecidos / Mass spectrometry and bio-molecules : structure-reactivity relation of peptides by ion/molecule reactions and ion mobility and search for new biomarkers in clinical medicini for chemo-selective imaging of tissues
The aim of this doctoral project was to study new applications of mass spectrometry (MS) to bio-molecules by using new techniques and recent approaches room pressure, with the goal of obtaining a more rapid and selective identification of an AA in a peptide sequence. Three-dimensional forms of the peptides and their fragment ions formed (a, b and y), were al

7. HLA-Bw4-B*57 and Cw*18 alleles are associated with plasma viral load modulation in HIV-1 infected individuals in Salvador, Brazil
Host genetic factors play an important role in mediating resistance to HIV-1 infection and may modify the course of infection. HLA-B alleles (Bw4 epitope; B*27 and B*57) as well as killer cell immunoglobulin-like receptors have been associated with slow progression of HIV-1 infection. OBJECTIVE: To evaluate the association between serological epitopes HLA-Bw

9. Mutations in retrotransposon AtCOPIA4 compromises resistance to Hyaloperonospora parasitica in Arabidopsis thaliana
Retrotransposons (RTEs) are a principal component of most eukaryotic genomes, representing 50%-80% of some grass genomes. RTE sequences have been shown to be preferentially present in disease resistance gene clusters in plants. Arabidopsis thaliana has over 1,600 annotated RTE sequences and 56 of these appear to be expressed because of the exact expressed se

10. Perseus:uma nova técnica para tratar árvores de sufixo persistentes / Perseus: a novel technique to handle persistent suffix trees
Due to the technological advances in molecular biology laboratories, biological databases are extremely voluminous and tend to become more voluminous as data on new genome organisms are available. This introduces the challenge of searching nucleotide sequences efficiently. The suffix tree is an access method used for several applications that search for thes

11. Tipos de homotopia dos grupos de gauge dos fibrados linhas quaterniônicos sobre esferas / Homotopy type of Gauge groups of quaternionic line bundles over spheres
Let p be a principal S POT. 3- bundle over a sphere S POT. n, with n>or =4. The subject of this work is to calculate the homotopy type of the gauge group G IND. pof these bundles p, extending the result determined by A. Kono [25] when n = 4. We present explicit formulas for the boundary operator in the homotopy exact sequence associated with the evaluation m

12. Comparação entre as técnicas de dacriocistografia por ressonância magnética e por raios X no diagnóstico da obstrução das vias lacrimais / Comparison between magnetic resonance and x-ray dacryocystography in the evaluation of the obstruction of the lacrimal apparatus
Epiphora is the hyperlachrymation related to an obstruction of the lachrymal drainage system. In such cases, the treatment is frequently surgical and the definition of the nature and level of obstruction demands imaging methods. Magnetic Resonance Imaging (MRI) may play a role in this issue. Objectives: Evaluate the efficacy of MR dacryocystography in the ob
