    Work‐related musculoskeletal disorders (MSDs) are a constellation of painful disorders, which could cause chronic disability. Multiple risk factors, both occupational and nonoccupational, may be involved. MSDs have been extensively studied in several countries; however, few studies have been carried out based on the relationship between MSDs and ethnicity

    Free monadic Tarski and MMI3-algebras

    Get PDF
    MMI3-algebras are a generalization of the monadic Tarski algebras as defined by A. Monteiro and L. Iturrioz, and a particular case of the MMIn+1-algebras defined by A. Figallo. They can also be seen as monadic three-valued £ukasiewicz algebras without a first element. By using this point of view, and the free monadic extensions, we construct the free MMI3-algebras on a finite number of generators, and indicate the coordinates of the generators. As a byproduct, we also obtain a construction of the free monadic Tarski algebras.Fil: Entizne, Rosana V.. Universidad Nacional del Sur. Departamento de Matemática; ArgentinaFil: Monteiro, Luiz F..

    Early stages of LDL oxidation: apolipoprotein B structural changes monitored by infrared spectroscopy.

    Changes in the conformation of apoliprotein B-100 in the early stages of copper-mediated low density lipoprotein oxidation have been monitored by infrared spectroscopy. During the lag phase no variation in structure is observed, indicating that copper binding to the protein does not significantly affect its structure. In the propagation phase, while hydroperoxides are formed but the protein is not modified, no changes in secondary structure are observed, but the thermal profile of the band corresponding to alpha-helix is displaced in frequency, indicating changes in tertiary structure associated with this conformation but not with beta-sheet components. When aldehyde formation starts, a decrease of approximately 3% in the area of bands corresponding to alpha-helix and beta-sheet is produced, concomitantly with an increase in beta-turns and unordered structure. The two bands corresponding to beta-turns vary as well under these conditions, indicating changes in these structures. Also at this stage the thermal profile shows variations in frequency for the bands corresponding to both alpha-helix and beta-sheet.The results are consistent with the hypothesis that as soon as the polyunsaturated fatty acids from the particle core are modified, this change is reflected at the surface, in the alpha-helical components contacting the monolayer.Fil: Chehin, Rosana Nieves.

    Clinical and laboratorial diversity in the bantu haplotype of sickle cell anemia

    Get PDF
    Several factors have been identified as possibly being responsible for the diversity of sickle cell anemia patients symptoms, including gender, age, haplotypes and hemoglobin F levels. The aim of this paper is to verify the clinical and laboratorial diversity of the Bantu haplotype. A descriptive study was performed of eighteen children and adolescents with sickle cell anemia and homozygous for the Bantu haplotype. Gender and age were assessed in respect to clinical and laboratorial features. Statistical analysis of the results was achieved using the EPIINFO program version 6.04. Children from 1 to 11 years old had more infections than adolescents from 12 to 19 and higher levels of hemoglobin F. The hematocrit was higher in girls. Higher levels of hemoglobin A2 were related to more infections, and higher levels of hemoglobin F were related to hematocrit values and lower numbers of infections and periods in hospital. This study suggests that there is diversity within the Bantu haplotype, which is possibly related to gender, age and hemoglobin A2 and hemoglobin F levels of patients.Muitos fatores são responsáveis pela diversidade de sintomas nos pacientes de anemia falciforme, entre eles: sexo, idade, haplótipos e nível de hemoglobina fetal. O objetivo deste estudo foi verificar a diversidade clínica e laboratorial dentro do haplótipo bantu. Realizou-se um estudo descritivo onde foram avaliados 18 crianças e adolescentes portadores de anemia falciforme e homozigóticos para o haplótipo bantu, relacionando sexo e idade com as características clínicas e laboratoriais, além de relacioná-las diretamente entre si. As amostras foram do tipo casuais simples. O tamanho da amostra teve uma variação de freqüência para o evento de 30% a 65% e nível de confiança de 99,9%. As análises estatísticas foram realizadas através do programa EPIINFO, versão 6.04b, com erro a de 5%. A faixa etária de 01 a 11 anos teve um maior número de infecções que a faixa de 12 a 19, além de níveis mais altos de hemoglobina fetal. Os valores do hematócrito foram maiores no sexo feminino. Níveis mais elevados de hemoglobina A2 foram relacionados com maior número de infecções, enquanto níveis mais elevados de hemo­globina fetal foram relacionados com maiores valores de hematócrito e menor número de crises álgicas/ano de acompanhamento. O número de transfusões/ano teve correlação positiva com o número de crises álgicas, de infecções e de inter­namentos. Este estudo sugere que há uma diversidade clínica e laboratorial dentro do haplótipo bantu e possivelmente está relacionado com o sexo, a idade e os níveis de hemoglobina fetal e A2 dos pacientes.Fundação Universitária de Ciências da Saúde de Alagoas Departamento de PediatriaUniversidade Federal de Alagoas Departamento de Clínica MédicaUniversidade Federal de Sergipe Departamento de PediatriaUniversidade Federal de São Paulo (UNIFESP) Departamento de Clínica MédicaUNIFESP, Depto. de Clínica MédicaSciEL

    [Resumo] Um dos principais objetivos do CMIA de Vila do Conde é a monitorização de descritores ambientais e consequentemente a divulgação dos valores, recursos e problemáticas ambientais. As atividades com maior sucesso entre os nossos visitantes são os percursos exploratórios que nos permite dar a conhecer inúmeras espécies e promover alterações de comportamento junto de diferentes faixas etárias que vão desde o pré-escolar até à idade adulta. No decorrer destes percursos, são preenchidas folhas de registo onde cada participante assinala as diferentes espécies que visualiza ao longo do percurso, são descritas algumas curiosidades sobre essas mesmas espécies encontradas e posteriormente a equipa do CMIA lança na plataforma do BioDiversity4all – Biodiversidade para todos, as espécies encontradas em cada grupo. Desenvolveu-se um estudo realizado aos participantes destes percursos, onde verificamos que estas atividades permitiram estimular, motivar e explicar ao público que nos visita que de uma forma lúdica todos podem contribuir diretamente para o levantamento da biodiversidade, contribuindo eficazmente para a conservação da biodiversidade e do meio ambiente que os rodeia[Abstract] The CMIA of Vila do Conde presents as its main goals, not only the monitoring of environmental indicators, as well as the correct interpretation and dissemination of the values, resources and issues surrounding the environment. The activities with greater success among our visitors are exploration trails that allowed meeting a numerous species and promoting the change of behaviors among diferent age groups ranging from preschool to adulthood. In these activities, they watched birds, plants and marine species and recorded Information about them in on-line platform: BioDiversity4all – Biodiversidade para todos. Developed a study to the participant of these activities, have made it possible to stimulate, motivate and explain to the public that visits us through a playful way everyone can contribute directly to the biodiversity survey and contributing efectively to the conservation of biodiversity and the environment that surrounds them
