1. Varredura espaço-temporal para identificação de áreas de risco para hospitalização de crianças por asma em Mato Grosso
RESUMO: Introdução: A asma resulta de complexa interação entre fatores genéticos, ambientais e socioeconômicos e representa um importante problema de saúde pública mundial. O objetivo deste trabalho foi identificar áreas prioritárias para ações de controle de asma em crianças. Método: Estudo ecológico no qual foi utilizada a varredura espa

2. The involvement of multiple thrombogenic and atherogenic markers in premature coronary artery disease
OBJECTIVE: To examine the association of atherogenic and thrombogenic markers and lymphotoxin-alfa gene mutations with the risk of premature coronary disease. METHODS: This cross-sectional, case-control, age-adjusted study was conducted in 336 patients with premature coronary disease (<50 years old) and 189 healthy controls. The control subjects had norma

3. Análise de genes diferencialmente expressos nas vias de sinalização (Hedgehog e Wnt) em carcinomas basocelulares humanos
Hedgehog (HH) and Wingless-Int (Wnt) signaling pathway are related to the process of cellular proliferation, differentiation, angiogenesis, matrix remodeling and homeostasis of stem cells. Over the years, several mutations in HH signaling pathway have been identified, including the loss of function mutations in ptch1 and the gain of function mutations in smo

4. Divergência genética entre acessos de Capsicum chinense Jacq. coletados no sudoeste goiano / Genetic divergence among Capsicum chinense Jacq accesses collected in southwest Goiás Brazil
Collecting and characterization of Capsicum chinense Jacq accesses are very important to recover and preserve genetic resources of this species; however, it is necessary to quantify the existing divergence for its use in breeding programs. The objective of this work was to verify the genetic divergence of 137 accesses of Capsicum chinense Jacq collected in s

5. Seleção de características por meio de algoritmos genéticos para aprimoramento de rankings e de modelos de classificação / Feature selection by genetic algorithms to improve ranking and classification models
Content-based image retrieval (CBIR) and classification systems rely on feature vectors extracted from images considering specific visual criteria. It is common that the size of a feature vector is of the order of hundreds of elements. When the size (dimensionality) of the feature vector is increased, a higher degree of redundancy and irrelevancy can be obse

6. Parâmetros genéticos de características reprodutivas de touros e vacas Gir Leiteiro / Genetic parameters for reproductive traits of bulls and cows Dairy Gyr breed
Data of 2,274 semen output from 200 sires, 7,055 measurements of age at first calving (AFC) from females and 141 measurements of scrotal circumference (SC) were used to determine genetic parameters for reproductive traits of males and females of Dairy Gyr breed. Were studied physical aspects such as volume (VOL), concentration (CONC), vigor (VIG), motility (

7. Extensões da estatística scan espacial utilizando técnicas de otimização multi-objetivo
This work presents three new extensions of Kulldorffs Spatial Scan Statistic for the detection and inference of spatial clusters. Consider a map divided into m regions with known populations at risk and number of cases of some disease. We would like to know if the cases are randomly distributed over the m regions or not; if the cases are not randomly distrib

8. 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

9. Análise populacional de Melipona marginata (Hymenoptera, Apidae, Meliponini) por meio de RFLP do DNA mitocondrial e microssatélites / Population analysis of Melipona marginata (Hymenoptera, Apidae, Meliponini) by RFLP of DNA mitochondrial and microsatellites
The tribe Meliponini (stingless bees) is present in all tropical regions of the world and has an important role in pollination. The genus Melipona has the highest number of species in the tribe. The specie Melipona marginata is considered the most ancestral within the genus, and like other species builds the nests in hollow of trees. Unfortunately several be

10. Characterization of the Brazilians species of Myotis Kaup, 1929 (Chiroptera: Vespertilionidae) and test on the phylogeography of Myotis nigricans (Schinz, 1821) and Myotis riparius Handley, 1960 / Caracterização das espécies brasileiras de Myotis Kaup, 1829 (Chiroptera: Vespertilionidae) e ensaio sobre filogeografia de Myotis nigricans (Schinz, 1821) e Myotis riparius Handley, 1960
Myotis is a highly diverse genus, with 103 species recognized so far, in addition to another 94 subspecies whose taxonomical status has not yet been completely evaluated. Twelve species are known to South America, among which five are considered polytypic, including Myotis nigricans. This taxon in considered a species complex. In order to characterize, both

11. Population genetic structure of lobeira (S. lycocarpum A. St.-Hil, Solanaceae), in natural and anthropogenic environmental in State of Goiás / Estrutura genética populacional em lobeira (Solanum lycocarpum A. St.-Hil., Solanaceae), em ambientes naturais e antropizados no estado de Goiás
Solanum lycocarpum A. St.-Hil. (Solanaceae) has a wide distribution in savanna biome. The species is common know as "fruta-do-lobo" due the "lobo-guará" frequently to eat your fruits. "Lobo-guará" is also the main seed disperser of the species. The species is used for local people to manufacture sweets and as medicine. The species f

12. Impacto da miscigenaÃÃo na aplicaÃÃo do HapMap para a populaÃÃo brasileira avaliados nos genes PTPN22 e VDR
The PTPN22 and VDR genes are commonly associated to several autoimmune diseases and complex phenotypes related to bone metabolism. The association of some of those polymorphisms are ethnic-specific, and therefore, admixture population studies must be conditionally evaluated to these factors. The Brazilian population is considered the most heterogeneous in th
