TL;DR: MDA-HPLC and MDA-TBARS are sensitive to detect change in MDA induced by acute exercise and are the most suitable technique for accurate detection of MDA in sports and exercise area due to its sensitivity and accuracy.
Abstract: The marker most frequently used to indicate the level of lipid peroxidation in the field of exercise and sports is malondialdehyde (MDA), which can be determined by many different techniques. However, there are few studies discussing differences and advantages of the methods for MDA assay in sports science field. The aim of the present study was to compare three techniques for quantification of MDA in plasma of humans subjected to acute exercise. MDA was determined by high performance liquid chromatography (MDA-HPLC), thiobarbituric acid reactive species (MDA-TBARS) and 1-methyl-2-phenylindole (MDA-MP) techniques in the plasma of 8 healthy male soccer athletes before and after acute exercise. Acute exercise significantly increased (P<0.05) plasma MDA concentration determined by MDA-HPLC (18%) and MDA-TBARS (56%) techniques. MDA-MP technique did not reveal significant differences, although it increased 25% after exercise. When correlated to the gold standard (MDA-HPLC), MDA-TBARS and MDA-MP techniques showed weak Lin concordance coefficients and non-significant correlation. Also, MDA-TBARS and MDA-MP techniques overestimated the MDA-HPLC technique by 100 and 122%, respectively. In conclusion, MDA-HPLC and MDA-TBARS are sensitive to detect change in MDA induced by acute exercise. MDA-HPLC is the most suitable technique for accurate detection of MDA in sports and exercise area due to its sensitivity and accuracy.

TL;DR: In this paper, a study of 452 adolescentes with idades entre 15 and 18 anos, selecionados of uma escola de ensino medio da cidade de Londrina, Parana, Brazil, found that 20% of the mocas and 16% of rapazes exhibited risco biologico for the desenvolvimento of doencas cardiovasculares.
Abstract: OBJETIVO: Oferecer informacoes descritivas e investigar a extensao com que os fatores de risco para doencas cardiovasculares de natureza comportamental estao associados aos fatores de risco biologicos na populacao jovem. METODOS: Amostra de 452 adolescentes (246 mocas e 206 rapazes) com idades entre 15 e 18 anos, selecionados de uma escola de ensino medio da cidade de Londrina, Parana. Fatores de risco de natureza comportamental foram analisados mediante pratica insuficiente de atividade fisica, ingestao excessiva de gorduras e de colesterol e uso de tabaco. Como indicadores dos fatores de risco biologicos recorreu-se ao sobrepeso, aos niveis elevados de pressao arterial e concentracoes nao-favoraveis de lipidios-lipoproteinas plasmaticas. RESULTADOS: Por volta de 20% das mocas e 16% dos rapazes apresentaram pelo menos um fator de risco biologico para o desenvolvimento de doencas cardiovasculares. O sobrepeso se associou significativamente com a ingestao excessiva de gorduras, enquanto a pressao arterial elevada se relacionou com o estilo de vida sedentario e o uso de tabaco. A excessiva ingestao de gorduras e de colesterol indicou risco aumentado de concentracoes indesejaveis de lipidios-lipoproteinas plasmaticas. Adolescentes fumantes tenderam a demonstrar risco de pressao arterial e de lipidios-lipoproteinas plasmaticas alterados duas vezes maior que nao-fumantes. CONCLUSAO: Os resultados reforcam a necessidade de que intervencoes direcionadas a adocao de um estilo de vida saudavel, incluindo pratica regular de atividade fisica, padroes dieteticos adequados e abstencao ao uso de tabaco, deverao ser iniciadas em idades jovens.

TL;DR: Results on the rotavirus types circulating in diarrheic piglets in Brazil disclosed a high diversity of strains with distinct G types including G1, G4, G5, and G9 and the novelty of P, the predominant human P specificity type, add strong evidence for the emergence of new strains through natural reassortment between rotaviruses of human and porcine origins.
Abstract: Rotavirus type G5 is a primarily porcine pathogen that has caused frequent and widespread diarrhea in children in Brazil and in piglets elsewhere. Initial results on the rotavirus types circulating in diarrheic piglets in Brazil disclosed a high diversity of strains with distinct G types including G1, G4, G5, and G9 and the novelty of P[8], the predominant human P specificity type. Those results add strong evidence for the emergence of new strains through natural reassortment between rotaviruses of human and porcine origins.

TL;DR: It is suggested that 8weeks of RT promote improvements on inflammatory levels, and the lipid and glycemic profile in obese older women, and further support the important role of RT in healthy aging.
