SUMMARY OBJECTIVE: The aim of this study was to measure the reliability, internal consistency, and construct validity of the Kidney Symptom Questionnaire for the Brazilian population. METHODS: This is a cross-cultural adaptation and questionnaire validation study. We included native Brazilians of both sex aged>18 years, as well as hypertensive and/or diabetic patients. All participants were assessed using Screening for Occult Renal Disease, EuroQol 5 Dimensions, 36-Item Short Form Survey, and the Kidney Symptom Questionnaire. We used Spearman’s coefficient (rho) to measure the correlations between the Kidney Symptom Questionnaire and other instruments; Cronbach’s alpha to measure internal consistency; and intraclass correlation coefficient, standard error of measurement, and minimum detectable change to measure test-retest reliability. RESULTS: The sample was formed by 121 adult participants, mostly female, with systemic arterial hypertension and/or diabetes mellitus. We found excellent reliability (intraclass correlation coefficient≥0.978), adequate internal consistency (Cronbach’s alpha≥0.860), and adequate construct validity on the Kidney Symptom Questionnaire domains; besides, we observed significant correlations between the Kidney Symptom Questionnaire and other instruments. CONCLUSION: The Brazilian version of the Kidney Symptom Questionnaire has adequate measurement properties to assess chronic/occult kidney disease in patients who do not require renal replacement therapy.

RESUMO Esta pesquisa teve como objetivo refletir sobre as experiências da docência no ensino superior, vivenciadas na intervenção com os conhecimentos da dança em uma disciplina do curso de licenciatura em Educação Física de uma universidade pública do estado de Minas Gerais, no período de 2013 a 2015. Participaram da pesquisa quatro turmas de quarto período, totalizando 173 alunos de ambos os sexos. O planejamento inicial da intervenção ocorreu em julho de 2013, sendo reestruturado nos semestres subsequentes. Adotamos o enfoque da pesquisa-ação em articulação com as contribuições dos estudos culturais. Constatamos que o estudo e a experimentação dos elementos coreológicos foram fundamentais à pesquisa corporal, subsidiando a prática, a criação, a reflexão e a apreciação, contribuindo para a educação das sensibilidades e diluição das dicotomias entre forma e conteúdo.

ABSTRACT This research aimed to reflect about the experiences of teaching in higher education, lived through the intervention of the knowledge of dance in a discipline of the teaching course in Physical Education of a public University of the State of Minas Gerais, from 2013 to 2015. Four classes of fourth quarter participated in the survey, totaling 173 students of both sexes. The initial planning of the intervention occurred in July 2013, and was restructured in subsequent semesters. We have adopted the approach of action research in conjunction with the contributions of cultural studies. We have found that the study and experimentation of coreológicos elements were fundamental to the body research, subsidizing practice, creation, reflection and appreciation, contributing to the education of sensitivities and the dilution of dichotomies between form and content.

O presente estudo objetivou a investigação da capacidade degradadora de uma linhagem bacteriana autóctone (isolada de amostras de solo contaminadas com derivados de petróleo) contra hidrocarbonetos de querosene de aviação. A linhagem foi caracterizada como Nocardia sp. A avaliação do seu potencial degradador deu-se realizada mediante testes com indicador redox e observações na redução da tensão superficial na fase aquosa. A degradação do querosene foi avaliada por métodos cromatográficos. Os experimentos foram realizados utilizando-se duas taxas de bioestímulo. Uma linhagem bacteriana Pseudomonas aeruginosa UFPEDA 39 foi utilizada como referência. A linhagem autóctone demonstrou alta eficiência na degradação de hidrocarbonetos do querosene bem como para produzir compostos ativos de superfície quando comparada com a linhagem de referência.

The aim of this study was to investigate the potential of degradation of an autochthonous bacterial strain, isolated from petroleum derivatives contaminated soil samples against jet fuel hydrocarbons. The autochthonous bacterial strain was characterized as Nocardia sp. Evaluation of their degrading abilities was carried out by presumptive assays as redox indicator test and by observations of surface tension decreases in aqueous medium. Degradation of jet fuel hydrocarbons was evaluated by chromatographic methods. Experiments were performed in flasks at two biostimulation rates. A bacterial strain of Pseudomonas aeruginosa UFPEDA 39 was utilized as a reference microorganism. The bacterial strain, identified as Nocardia sp, demonstrate high ability to degrade jet fuel compounds as well as to produce surface active compounds when compared to the reference microrganism.

O objetivo deste trabalho foi investigar a potencialidade de leveduras que degradam óleo Diesel, visando aplicação em processo de biorremediação de áreas impactadas pelo referido poluente. As culturas, identificadas como Rhodotorula aurantiaca UFPEDA 845 e Candida ernobii UFPEDA 862, foram as selecionadas na etapa inicial. Quanto aos ensaios de biodegradabilidade, a levedura Candida ernobii UFPEDA 862 degradou totalmente: tetradecano, 5 metil-octano e octadecano, e parcialmente decano (60,8%) e nonano (21,4%), enquanto que a Rhodotorula aurantiaca UFPEDA 845 apresentou percentuais de degradação de 93,0% para decano, 38,4% para nonano e 22,9% para dodecano.

The aim of this work was to investigate the potential of the diesel oil degrading yeasts to use them in bioremediation of areas contaminated by this pollutant. The cultures, identified as Rhodotorula aurantiaca UFPEDA 845 and Candida ernobii UFPEDA 862, were selected at the initial stage. In the course of the biodegradation assays, C. ernobii degraded tetradecane, 5 methyl-octane and octadecane completely and decane (60.8%) and nonane (21.4%) partially whilst R. aurantiaca presented degradation percentages of 93% for decane, 38.4% for nonane and 22.9% for dodecane.
