    Exercise is a double-edged sword: when practiced in moderation, it increases the expression of antioxidant enzymes, but when practiced strenuously it causes oxidative stress and cell damage. In this context, polymorphisms in the interleukin (IL)-6 gene should be investigated better because they can influence performance, at least in exercise that generates oxidative stress and leads to muscular injuries with consequent inflammation. In this work, we investigated the influence of IL-6 –174 G/C polymorphism on tissue damage and inflammation markers, lipid peroxidation, hemogram and lipid profile of runners before and after ingestion of 400 mg of pequi oil in capsules supplied daily for 14 consecutive days. The IL-6 genotypes were associated with significant differences in lipid peroxidation, with the CC mutant having lower values. There were also significant differences among these genotypes in the response to supplementation with pequi oil, exercise-induced damage and C-reactive protein (CRP) levels. The best protection against damage was observed with the heterozygous genotype. Although the CC genotype showed an increase in CRP levels after supplementation, the lack of a positive correlation between triglycerides and high-sensitivity CRP in this mutant genotype after supplementation indicated a protective effect of pequi. These findings deserve further investigation, particularly with regard to the quantification of circulating IL-6 concentrations

    The mitochondrial elongation factor LeEF-Tsmt is regulated during tomato fruit ripening and upon wounding and ethylene treatment

    A gene encoding an elongation factor LeEF-Tsmt that participates in the protein synthesis process in mitochondria shows strong expression in ripening fruit as compared to other organs. It is strongly up-regulated during the first stages of the ripening process in parallel with the climacteric rise in respiration. LeEF-Tsmt expression is stimulated by ethylene, wounding and high temperature but ethylene-insensitive mutants exhibit normal expression. Transgenic fruit have been generated in which LeEF-Tsmt has been constitutively up- and down-regulated. Surprisingly, altering the expression of the gene by genetic transformation with antisense and sense LeEF-Tsmt constructs did not affect the pattern of respiration and ethylene production during ripening and upon wounding. In addition, expression of the alternative oxidase gene which is known to play an important role in respiratory climacteric was not affected. Possible reasons for the absence of effect on respiration of variations of LeEF-Tsmt gene expression are discussed

    Creating an iDTV Application from Inside a TV Company: A Situated and Participatory Approach

    Get PDF
    Part 2: Organizational Semiotics and ApplicationsInternational audienceTV is a highly social and massive media that is worldwide available. The Interactive Digital TV represents a new device that is still constructing its identity. Designing applications for it is a challenging task, partially because of its intrinsic complex context and the lack of theoretical and methodological referential to support design activities. In this paper, we argue for a Socially Aware Computing approach to the design of iDTV applications, articulating artifacts and methods from Organizational Semiotics and Participatory Design. A case study on requirements for the design of an iDTV application is situated in the practical context of a Brazilian broadcasting TV Company. The results show benefits of using informed artifacts and methods in participatory and situated practices, indicating that it is possible and viable to make socially aware design in industrial settings

    Monografia (graduação)—Universidade de Brasília, Faculdade de Economia, Administração e Contabilidade, Departamento de Administração, 2014.O crescimento exponencial do e-commerce tem gerado a necessidade de suprir essa demanda de entregar as mercadorias diretamente no domicílio de seus clientes. A pesquisa é um estudo do principal operador logístico do e-commerce no Brasil, os Correios. Trata-se de organização pública tradicional, presente em todos os municípios do país com uma estrutura capaz de movimentar mercadorias e documentos como nenhuma outra empresa. Esse trabalho pretende avaliar a efetividade do processo logístico de entrega de encomendas dos Correios em Brasília, com o objetivo de verificar se a empresa cumpre com o nível de serviço prometido. Está avaliação se baseou em dados e informações qualitativas e quantitativas obtidas em pesquisa documental e entrevistas, além de acompanhamento de um dia de trabalho de um carteiro na entrega. Procurou apresentar resultados objetivos com base na chamada “voz do processo” interno, tais como: o percentual de entrega de encomendas no prazo, o percentual de encomendas que não se consegue entregar e que precisam ser devolvidas ao expedidor, identificando os motivos deste fato e ainda se existe risco de roubo ou extravio de encomendas e em que percentuais. Mas, além da voz do processo se procurou ouvir, também, a “voz do cliente” para verificar como ele avalia os serviços de distribuição dos Correios, qual é sua expectativa e qual é o seu nível de satisfação

    Female urogenital reconstruction in a case of sexual development disorder (46, XY) with cloacal exstrophy associated with diphallia

    Get PDF
    Disorders (or differences) of Sex Development (DSD) comprise a state of genetic, gonadal and genital variation. Among the conditions associated with DSD is cloacal exstrophy, a rare congenital malformation part of the exstrophy-epispadias malformation complex. Thus, the case of a patient with rare involvement of DSD 46, XY cloacal exstrophy associated with diphallia who underwent surgical treatment for female urogenital reconstruction is reported. The patient's electronic medical record was reviewed after presenting and accepting the Informed Consent. Sociodemographic and clinical-epidemiological variables and pre- and postoperative data were analyzed. The patient was 20 years old, white and raised considering to be female. She was born with cloacal exstrophy, with severe morphological changes in the external genitalia, and submitted to terminal ileostomy, cystoplasty, and rudimentary large bowel colectomy during the neonatal period. At 13 years of age, the patient reported discomfort with the appearance of her external genitalia and the need for constant use of diapers due to urinary incontinence. The patient underwent reconstruction of the urinary and genital tracts during adolescence besides a genitoplasty followed by regular vaginal dilation. At age 17, she reported feeling satisfied with the surgical result, denied discomfort with the current aspect of her genitalia and mentioned identifying herself with the female and male genders, with increased adherence to typically female behaviors. A supposedly favorable outcome in the late adolescence of a DSD 46, XY cloacal exstrophy subject who underwent surgical adaptation for sexual definition after a multidisciplinary approach was reported. The patient revealed a non-binary gender identity, absence of gender dysphoria, satisfaction with her own body and androphilic sexual orientation
