OBJETIVOAnalisar os efeitos de 20 semanas de treinamento concorrente sobre as variáveis de composição corporal, perfil lipídico e diagnóstico da esteatose hepática em adolescentes obesos.MÉTODOSRealizou-se um ensaio clínico aberto com 34 adolescentes obesos com idades entre 12 e 15 anos. Foram analisados gordura corporal total e de tronco, colesterol total e suas frações (HDL, LDL e VLDL) e triglicérides, sendo realizado exame de ultrassonografia de abdome superior para diagnosticar esteatose hepática. Os participantes foram submetidos ao treinamento concorrente (associação de treino com pesos e exercício aeróbio) três vezes por semana, com duração de uma hora-aula durante 20 semanas. Para o tratamento estatístico, foram realizados o teste t de Student pareado e a análise de frequência, a fim de verificar as reduções relativa e absoluta do diagnóstico da esteatose hepática, adotando-se p<0,05.RESULTADOSOs adolescentes estudados apresentaram melhoras significativas da composição corporal, com diminuição do percentual de gordura total, da massa gorda total, da gordura de tronco e do aumento da massa magra, além de redução do tamanho dos lóbulos do fígado, dos índices de prevalência da esteatose hepática, do colesterol total e LDL-colesterol.CONCLUSÕESO treinamento concorrente foi efetivo por promover melhorias significativas de variáveis da composição corporal e do perfil lipídico, além de reduzir a prevalência da esteatose hepática.

The over-production of reactive oxygen species (ROS) can cause oxidative damage to a large number of molecules, including DNA, and has been associated with the pathogenesis of several disorders, such as diabetes mellitus (DM), dyslipidemia and periodontitis (PD). We hypothesise that the presence of these diseases could proportionally increase the DNA damage. The aim of this study was to assess the micronucleus frequency (MNF), as a biomarker for DNA damage, in individuals with type 2 DM, dyslipidemia and PD. One hundred and fifty patients were divided into five groups based upon diabetic, dyslipidemic and periodontal status (Group 1 - poor controlled DM with dyslipidemia and PD; Group 2 - well-controlled DM with dyslipidemia and PD; Group 3 - without DM with dyslipidemia and PD; Group 4 - without DM, without dyslipidemia and with PD; and Group 5 - without DM, dyslipidemia and PD). Blood analyses were carried out for fasting plasma glucose, HbA1c and lipid profile. Periodontal examinations were performed, and venous blood was collected and processed for micronucleus (MN) assay. The frequency of micronuclei was evaluated by cell culture cytokinesis-block MN assay. The general characteristics of each group were described by the mean and standard deviation and the data were submitted to the Mann-Whitney, Kruskal-Wallis, Multiple Logistic Regression and Spearman tests. The Groups 1, 2 and 3 were similarly dyslipidemic presenting increased levels of total cholesterol, low density lipoprotein cholesterol and triglycerides. Periodontal tissue destruction and local inflammation were significantly more severe in diabetics, particularly in Group 1. Frequency of bi-nucleated cells with MN and MNF, as well as nucleoplasmic bridges, were significantly higher for poor controlled diabetics with dyslipidemia and PD in comparison with those systemically healthy, even after adjusting for age, and considering Bonferroni's correction. Elevated frequency of micronuclei was found in patients affected by type 2 diabetes, dyslipidemia and PD. This result suggests that these three pathologies occurring simultaneously promote an additional role to produce DNA impairment. In addition, the micronuclei assay was useful as a biomarker for DNA damage in individuals with chronic degenerative diseases.

The uninterrupted rise in emission of greenhouse gases open way to the use of biofuels, due to politics that focus on fuel safe, clean and renewable. The use of microalgae for biodiesel production has been described as one of the most promising sources of biomass for biofuels. The aim of this study was to evaluate the extraction and lipid profile of the microalgae Dunaliella tertiolecta, Isochrysis galbana and Tetraselsim gracilis. The extractions were performed with solvents chloroform /methanol and petroleum ether. The lipid profile was analyzed by gas chromatography after transesterification.The petroleum ether showed more efficiency in the extraction, the best result obtained was in the microalgae D. tertiolecta with 19.52% of lipid. The lipid profile analysis indicated a biodiesel stable to oxidation and elevated viscosity
