1. Association between NDO-LID and PGL-1 for leprosy and class I and II human leukocyte antigen alleles in an indigenous community in Southwest Amazon
Abstract The frequencies of the Human leukocyte antigen (HLA) alleles in the Puyanawa indigenous reserve population and their association with the NDO-LID and ELISA PGL-1 rapid serological test was assessed. This was a cross-sectional study with an epidemiological clinical design conducted in two indigenous communities in the state of Acre, Brazil. Blood was

2. Phenylalanine Hydroxylase (PAH) Genotyping in PKU Argentine Patients
Abstract Phenylketonuria (PKU, OMIM 261600) is predominantly caused by mutations in the PAH gene. One hundred and three Argentine PKU patients were studied by Sanger sequencing; 101 were completely characterized (90.3% were compound heterozygotes). Fifty-four different pathogenic variants were identified. Mutations were distributed all along the PAH gene but

3. THE INFLUENCE OF ACE I/D GENE POLYMORPHISM IN AMATEUR AMERICAN FOOTBALL ATHLETES IN BRAZIL
RESUMO Introdução O desempenho físico depende de uma série de propriedades biológicas e mecânicas. Esses diferentes fenótipos são relacionados através da complexa interação entre o ambiente e o perfil genético individual. A hipótese é que existe um componente hereditário que interfere na aptidão física. O gene da ECA destaca-se entre os ge

4. Screening for FMR1 expanded alleles in patients with Autism Spectrum Disorders in Manaus, Northern Brazil
Abstract: Fragile X Syndrome (FXS) is a neurodevelopmental disorder caused by dynamic mutations of a CGG repetition segment in an X chromosome’s single gene. It is considered the leading hereditary cause of both Autism Spectrum Disorders and Intellectual Disability. Some authors suggest that all individuals diagnosed with some of these latter conditions to

5. HLA-B*14 allele predicts HIV-1 mother-to-child-transmission, in Salvador, Brazil
ABSTRACT Background: Class I human leukocyte antigens, especially the molecules encoded at the B locus (HLA-B), are associated with AIDS progression risk. Different groups of HLA-B alleles have been associated to a protective effect or increasing susceptibility to HIV infection and are expressed from the earliest stages of gestation. Objective: The aim of

6. Minimal prevalence of Huntington’s disease in the South of Brazil and instability of the expanded CAG tract during intergenerational transmissions
Abstract Huntington’s disease (HD) is due to dominant expansions of the CAG repeat of the HTT gene. Meiotic instability of the (CAG)n might impact the disorder frequency. We report on HD minimal prevalence in Rio Grande do Sul (RS) state, Brazil, and on intergenerational instability of the (CAG)n in HD families. Symptomatic and at-risk subjects from 179 HD

7. Spatial and temporal evolution of imidazolinone-resitant red rice in 'Clearfield' rice cultivations
Resumo: O objetivo deste trabalho foi avaliar a distribuição de populações de arroz-vermelho (Oryza sativa) resistente às imidazolinonas (R-IMI), a frequência dos alelos que conferem resistência às IMI, e a adoção de práticas agronômicas aplicadas ao controle do arroz-vermelho, em estações de cultivo e regiões produtoras de arroz do Estado do

8. Diversidade e estrutura genética de populações de Podocarpus lambertii Klotzsch ex Endl. na floresta ombrófila mista em Santa Catarina
Resumo Podocarpus lambertii (Podocarpaceae) é conhecido popularmente como pinheiro-bravo. Ocorre em várias formações florestais da Mata Atlântica, principalmente na Floresta Ombrófila Mista. Devido à intensa exploração madeireira sofrida pela espécie, ela está presente na categoria “Quase ameaçada” da Lista Vermelha das Espécies Ameaçadas d

9. Genotyping of Dombrock and Lutheran blood group systems in blood donors from the southwestern region of the state of Paraná, Southern Brazil
Abstract Background Lutheran and Dombrock are two blood group systems with low immunogenic antigens; they can cause mild-to-moderate transfusion reactions. For both, immunophenotyping is not performed in the pretransfusion routine in Brazil. In addition, the distribution of their antigenic frequencies is an important marker of ethnicity. Thus, the goal of t

11. Evaluation of insecticide resistance in Aedes aegypti populations connected by roads and rivers: the case of Tocantins state in Brazil
BACKGROUND The longstanding application of insecticides for vector control without periodic monitoring of the population response to these chemicals can directly drive the selection of resistant populations of vector mosquitoes. Tocantins is the newest state of the Brazilian Federation. Despite a historically high number of dengue cases, studies and monito

12. Molecular genotyping of G6PD mutations and Duffy blood group in Afro-descendant communities from Brazilian Amazon
Abstract Glucose-6-phosphate dehydrogenase deficiency (G6PDd) and Duffy-negative blood group are two red blood cells variants that confer protection against malaria. In this study, the distribution of the most common G6PD variants (G6PD*A-, GGPD*A and G6PD Mediterranean) and the major alleles of the Duffy blood group (FY*A, FY*B and FY*BES) were investigated
