Anxiety and depression symptoms in women with and without binge eating disorder enrolled in weight loss programs
OBJECTIVES: 1) To investigate the association between binge eating scores, anxiety and depression symptoms, and body mass index (BMI), and 2) to assess the presence of differences in severity of anxiety symptoms, severity of depression symptoms, and BMI in women with and without binge eating disorder. METHOD: The sample comprised 113 women aged between 22 and 60 years (39.35±10.85) enrolled in weight loss programs in Porto Alegre, southern Brazil. The following instruments were used: structured interview, Brazilian Economic Classification Criteria, Beck Anxiety Inventory, Beck Depression Inventory, and Binge Eating Scale. Data were analyzed using descriptive and inferential statistics. RESULTS: A positive association was found between binge eating scores and the severity of anxiety symptoms (p OBJETIVOS: 1) Investigar a associação entre escores de compulsão alimentar, sintomas de ansiedade e de depressão e índice de massa corporal (IMC); e 2) verificar se existe diferença na intensidade dos sintomas de ansiedade, dos sintomas depressivos e no IMC em mulheres com e sem compulsão alimentar. MÉTODO: A amostra foi composta de 113 mulheres com idade entre 22 e 60 anos (39,35±10,85), participantes de programas de redução de peso na cidade de Porto Alegre, sul do Brasil. Foram aplicados os seguintes instrumentos: entrevista estruturada, Critérios de Classificação Econômica Brasil, Inventário de Ansiedade de Beck, Inventário de Depressão de Beck e Escala de Compulsão Alimentar Periódica. Os dados foram analisados utilizando-se estatística descritiva e inferencial. RESULTADOS: Houve associação positiva entre os escores de compulsão alimentar e a intensidade dos sintomas de ansiedade (p < 0,001) e de depressão (p < 0,001). Não foi observada associação significativa (p = 0,341) entre IMC e escores de compulsão alimentar. Houve diferença significativa entre mulheres com e sem compulsão alimentar com relação à intensidade dos sintomas de ansiedade (p < 0,001) e depressão (p < 0,001). Não foi encontrada diferença significativa entre os grupos com relação ao IMC (p = 0,103). CONCLUSÃO: Os achados deste estudo mostraram que a compulsão alimentar está associada a sintomas de ansiedade e de depressão, porém não está associada ao IMC
Plant lectins: the ties that bind in root symbiosis and plant defense
Lectins are a diverse group of carbohydrate-binding proteins that are found within and associated with organisms from all kingdoms of life. Several different classes of plant lectins serve a diverse array of functions. The most prominent of these include participation in plant defense against predators and pathogens and involvement in symbiotic interactions between host plants and symbiotic microbes, including mycorrhizal fungi and nitrogen-fixing rhizobia. Extensive biological, biochemical, and molecular studies have shed light on the functions of plant lectins, and a plethora of uncharacterized lectin genes are being revealed at the genomic scale, suggesting unexplored and novel diversity in plant lectin structure and function. Integration of the results from these different types of research is beginning to yield a more detailed understanding of the function of lectins in symbiosis, defense, and plant biology in general
Barrier Tissue Macrophages: Functional Adaptation to Environmental Challenges
Macrophages are found throughout the body, where they have crucial roles in tissue development, homeostasis and remodeling, as well as being sentinels of the innate immune system that can contribute to protective immunity and inflammation. Barrier tissues, such as the intestine, lung, skin and liver, are exposed constantly to the outside world, which places special demands on resident cell populations such as macrophages. Here we review the mounting evidence that although macrophages in different barrier tissues may be derived from distinct progenitors, their highly specific properties are shaped by the local environment, which allows them to adapt precisely to the needs of their anatomical niche. We discuss the properties of macrophages in steady-state barrier tissues, outline the factors that shape their differentiation and behavior and describe how macrophages change during protective immunity and inflammation
Jakt på papperslösa gör oss till en polisstat
Regeringen föreslår nio åtgärder för att hitta och utvisa papperslösa. Det kommer att slå hårt och främst gå ut över redan svaga och jagade människor. Vi uppmanar därför regeringen att ta tillbaka åtgärderna, skriver 43 forskare
