Physiological quality, content and activity of antioxidants in soybean seeds artificially aged.

ABSTRACT - The objective of this study was to evaluate physiological quality, content, and activity of antioxidants, in soybean seeds subjected to accelerated aging during different periods. Seeds of cultivars BRS 258, BRS 262 and BRS 268, subjected to accelerated aging during 12, 24, 36 and 48 hours and non-aged seeds were used. After each aging period, the seed were evaluated by tests of: germination; first count and tetrazolium. The total of phenolic compounds, total flavonoides, total of isoflavones, and activity for eliminating ABTS°+ radicals were quantified. There were differences among cultivars according to vigor and viability only after seeds were aged. Cultivars BRS 158 and BRS 268 have shown better seed physiological quality in each aging period; however, not presenting higher amounts of isoflavones and efficiency in removing free radicals. For all cultivars, the values for total of phenolic compounds, as well as total of flavonoids have shown quadratic positive behavior; the values for isoflavones remained constant and the vigor and viability showed contrary trend to activity of antioxidant agents. RESUMO: Qualidade fisiológica, conteúdo e atividade de antioxidantes presentes em sementes de soja envelhecidas artificialmente. O objetivo deste trabalho foi avaliar a qualidade fisiológica, o conteúdo e a atividade de agentes antioxidantes presentes em sementes de soja envelhecidas durante diferentes períodos. Foram utilizadas sementes das cultivares BRS 258, BRS 262 e BRS 268, envelhecidas durante 12, 24, 36 e 48 h e sementes não envelhecidas. Após cada período de envelhecimento, as sementes foram avaliadas pelo testes de: germinação; primeira contagem e tetrazólio. Foram quantificados: compostos fenólicos totais; flavonóides totais; total de isoflavonas e atividade eliminadora do radical ABTS°+. Houve diferença entre as cultivares em relação ao vigor e viabilidade somente quando foram envelhecidas. BRS 158 e BRS 268 apresentaram melhor qualidade fisiológica de sementes em cada período de envelhecimento, porém, não apresentaram maior quantidade de isoflavonas e eficiência no sequestro dos radicais livres. Para todas as cultivares, os valores de compostos fenólicos totais, assim como os flavonóides totais, apresentaram comportamento quadrático positivo; os valores das isoflavonas permaneceram constantes e o vigor e a viabilidade apresentaram tendência contrária à atividade dos agentes antioxidantes

Relationship between obstructive sleep apnea and obesity: a review of endocrine, metabolic and nutritional aspects

Currently OSAS is recognized as an independent predictor for obesity, and this, in turn, is characterized as the main risk factor for OSAS. This article aims to review the existing literature on the relationship between OSA and obesity, whereas endocrine and metabolic aspects of this relationship and to discuss the role of weight loss in the treatment of this syndrome. Several studies have shown that OSA is directly associated with endocrine disorders such as leptin levels and ghrelin, hormones related to hunger and satiety, and can contribute to increased insulin resistance and cortisol, increasing the risk of chronic diseases such as cardiovascular. Whereas OSAS is an independent risk factor for hypertension and cardiovascular disease, as well as being strongly associated with obesity and insulin resistance, various treatments have been currently proposed, including surgery, oral appliances, CPAP use, as well as changes in lifestyle, which focus on inclusion of exercise and decreased calorie intake, which promotes the reduction of anthropometric measurements and improvement in AHI and respiratory parameters. It is concluded that OSA and obesity trigger endocrine and metabolic disorders, which can negatively affect the health of the individual. Thus, it can be said that the reduction of body mass is clinically important for obese patients with OSAS and should be a measure of important attention in the treatment of this disease.Atualmente a SAOS é reconhecida como um preditor independente para a obesidade, e esta, por sua vez, caracteriza-se como o principal fator de risco para a SAOS. Com isso, o presente artigo visa revisar a literatura existente sobre a relação entre SAOS e obesidade, considerando os aspectos endócrinos e metabólicos desta relação, bem como discutir o papel da perda de peso no tratamento desta síndrome. Diversos estudos têm demonstrado que a SAOS está diretamente associada às alterações endócrinas, como os níveis de leptina e grelina, hormônios relacionados a fome e saciedade, bem como pode contribuir para o aumento da resistência à insulina e do cortisol, elevando o risco de doenças crônicas, como as cardiovasculares. Considerando que a SAOS é fator de risco independente para hipertensão e doenças cardiovasculares, além de ser fortemente associada com a obesidade e a resistência à insulina, diversos tratamentos têm sido propostos atualmente, incluindo cirurgias, aparelhos intra orais, uso de CPAP, bem como mudanças de estilo de vida, as quais focam na inclusão de exercícios físicos e diminuição da ingestão calórica, o que promove a redução de medidas antropométricas e melhora no IAH e parâmetros respiratórios. Conclui-se que a SAOS e a obesidade desencadeiam alterações endócrinas e metabólicas, as quais podem atuar negativamente na saúde do indivíduo. Desta forma, pode-se afirmar que a redução da massa corporal é clinicamente importante para pacientes obesos com SAOS, devendo ser uma medida de importante atenção no tratamento desta doença.Univ Fed Sao Paulo UNIFESP, Dept Psicobiol, Sao Paulo, SP, BrazilUniv Fed Sao Paulo UNiFESP, Dept Biociencias, Sao Paulo, SP, BrazilUniv Fed Uberlandia, Fac Med, Uberlandia, MG, BrazilUniv Fed Minas Gerais, Dept Educ Fis & Esporte, Belo Horizonte, MG, BrazilUniv Fed Sao Paulo UNIFESP, Dept Psicobiol, Sao Paulo, SP, BrazilUniv Fed Sao Paulo UNIFESP, Dept Biociencias, Sao Paulo, SP, BrazilWeb of Scienc

Prevalence of Helicobacter pylori infection and associated factors among adults in Southern Brazil: a population-based cross-sectional study

BACKGROUND: Helicobacter pylori (Hp) infection is associated with several upper gastrointestinal disorders. Local data on the epidemiology of the infection are scarce in Brazil. The purpose of this study is to measure the prevalence rate and to explore the associated factors among the adult population living in Pelotas, a southern Brazilin city. METHODS: This was a population-based cross-sectional study. Through a multi-stage sampling method all individuals 20 years and over living at the selected households at the urban area of the city were interviewed regarding past and current socio-economic indicators; demographic characteristics; nutritional and behavioural habits; and history of upper gastrointestinal symptoms.Hp infection was ascertained through the (13)C-UBT. Due to the high prevalence, data were analysed through robust Poisson regression. All analyses took into account the family clustering of the data. RESULTS: Among 563 eligible individuals, 363 agreed to perform the (13)C-UBT (refusal rate of 35.5%). Refusals were associated with female sex, consumption of mate drinking, and presence of upper gastrointestinal symptoms. The prevalence rate of H. pylori infection was 63.4% (95%CI 59.3%–69.3%). In crude analyses, prevalence was associated with increasing age, non-white skin colour, lower current family income, lower education level, higher size of the family, low socio-economic conditions in childhood, higher number of siblings and attendance to day-care centres in childhood, and presence of dyspeptic symptoms. In adjusted analysis the level of education of the father was inversely associated with the infection, whereas number of siblings and attendance to day-care centre in childhood were directly associated with it. Non-white skin colour remained significantly associated with increased prevalence even after allowing for past and current socio-economic characteristics, age and sex. Compared to non-symptomatic individuals, those reporting dyspeptic symptoms presented a higher prevalence of the infection even after allowing for current and past socio-economic conditions, ethnicity, age, and sex. CONCLUSION: Hp infection is as common among adults in southern Brazil as it is in other developing countries. Socio-economic conditions in childhood besides ethnicity and presence of dyspeptic symptoms were the factors significantly associated with the infection
