Physical activity is one of the main components of a healthy lifestyle, responsible for many health benefits. Despite being considered important for both disease prevention and health promotion there is high prevalence of sedentary behavior in the elderly population. Questionnaires are practical and feasible instruments for assessing levels of physical activity. However, they may have limitations in older age ranges. Accelerometers, movement sensors that make physical activity data more objective, emerge as reliable measuring devices. Aim: Determine the validity of the International Physical Activity Questionnaire (IPAQ) adapted for elderly with accelerometry in elderly women. Methods: 57 elderly women, with mean age of 66.05 ± 5.98 years who took part in hypertension control and physical activity incentive programs were assessed in relation to objective and subjective measures of physical activity. The accelerometer was used for 07 consecutive days, 24 hours per day before the IPAQ was applied. Data were analyzed using measures of central tendency and dispersion to characterize the sample according to variables collected. To check the validity of the data we used the Spearman correlation test, considering a significance level of p <0.05. Results: With respect to the categories of physical activity obtained by IPAQ, 46.4% developed moderate physical activity, followed by a high (30.3%) and low level (23.2%). There was a negative correlation only between self-reported time spent sitting and time spent on light activities as measured by accelerometry (r = - 0.408; p = 0.003) and mean activity level (counts/min) with physical activity levels evaluated by IPAQ (r = 0.297; p = 0.036). Conclusion: The IPAQ used in elderly women shows moderate to low validity levels according to accelerometry measures. Assessment of sedentary activities exhibited acceptable levels compared to accelerometry; however, moderate (r = 0.096; p > 0.05) to vigorous (r = 0.098; p > 0.05) activities were not correlated, demonstrating the inability of IPAQ to evaluate this type of activity in elderly women

This work studies the dispute by Party Communist s memory in Brazil during and after division which it resulted in the appearance of two parties entitled communists, in the brazilian political context, in the final of the fifties and beginning of the sixties: the Brazilian Communist Party (in Portuguese, Partido Comunista Brasileiro) and the Communist Party of Brazil (in portuguese, Partido Comunista do Brasil). Along of yours three chapters, the author tries to answer some questions as: what were the elements which constituted the Communist Party s memory, in the period from 1922 to 1956? At which moment did this memory pass to be fiercely contested? Who and which documents reveal this? How did it happen the dispute by this memory? The approach to topic consider which the production of memory by Communist Party and the dispute for your possession by communists of PCB and of PCdoB happened in scope of national reality and of party, spaces notions understand from concept of memory developed for authors as Halbwachs, Le Goff, Pollack and Pierre Nora. To explain the objectives of historical research it has used as methodology the exam and the interpretation of documentary and bibliographical sources, with priority for the party s documents then it was depicted a collective interpretation about the events considered more importants. The sites of Partido Comunista do Brasil (www.pcdob.org.br or vermelho.org.br) and of Partido Popular Socialista (www.pps.org.br) also went consulted

O presente estudo discute a formação de Redes Sociais no cotidiano da Estratégia Saúde da Família, a partir de aportes da teoria sociológica sobre redes, interações, dádiva e reconhecimento. O objetivo geral é analisar as redes sociais locais em saúde a partir da interação de usuários e profissionais da Estratégia Saúde da Família na Unidade de Saúde de Ligéia, em Natal, RN. Seus objetivos específicos são: Mapear as redes sociais locais em saúde existentes no território adscrito; Identificar os tipos de interações cotidianas entre os sujeitos; Compreender a percepção dos sujeitos sobre o processo de formação de redes sociais a partir das interações. Caracteriza-se enquanto pesquisa qualitativa exploratória cujos sujeitos foram profissionais e usuários vinculados à referida unidade de saúde. Para a coleta de dados foram utilizadas entrevistas individuais semiestruturadas e debates em grupos focais, estimulados pela Metodologia de Análise de Redes do Cotidiano (MARES), pertinente para abordar a complexidade das relações sociais e mapear os diferentes conteúdos expressos e as formas de mobilização coletiva. A análise dos dados foi realizada através da Técnica de Análise Temática de Conteúdo, proposta por Minayo. Os resultados foram interpretados à luz das Teorias da Dádiva (Mauss) e do Reconhecimento (Honneth). Os sujeitos visualizaram: Rede Virtual (28,20%); Rede de Atenção à Saúde (25,64%); Redes de Usuários (17,95%); Rede Pessoal (10,26%); Conselho Comunitário (10,26%); Escolas (7,69%). Os participantes não perceberam os arranjos familiares enquanto Redes Sociais. Os tipos de interações sociais identificadas foram: Confrontação/Negociação (41.02%); Harmônicas (25,70%); Correlativas (17,90%); Definidas pela Organização (15,38%). A formação de redes sociais ocorre a partir de interações cotidianas entre pessoas, pela articulação inseparável de conteúdos e formas, catalisadas pelo contexto, experiência e cognição, valorizando a liberdade, a expressividade e a diversidade dos parceiros de significação. Foram encontradas duas categorias, na percepção dos sujeitos, sobre a formação de redes sociais do cotidiano: Diálogo e Encontro. Validamos e recomendamos o uso da metodologia MARES: Na formação, para despertar uma visão mais tolerante e humana de si e do outro; Na avaliação qualitativa dos serviços, por facilitar a reflexão sobre a prática e (re)organização do processo de trabalho; Na comunidade, para estimular movimentos sociais existentes ou emergentes. A aposta no circuito da dádiva e do reconhecimento recíproco, durante o trânsito nas redes sociais em saúde, pode ser capaz de tecer uma práxis transformadora, pela busca e alcance de confiança, respeito e estima, nos espaços de encontro entre usuários e profissionais da Estratégia Saúde da Família

The study in screen it has as objective the understanding of the space circuit of production and the circles of cooperation of the soy that if develop in the Maranhão in the technician-scientific-informational period. Characterized for the material and incorporeal flows if they develop in the Maranhão, from the moment where it had a process of integration of the maranhense territory while peripheral space of the capitalist dynamics, that if gave through the politics of regional integration created by the State, but when it had a process of selective modernization, also partial and conservative of the agriculture, that made possible the significant increase of the production and reproduction of the capital. The study sample that with the advent of the soy, had a concentration of the production techniques, mainly in the agricultural region of Balsas, due to bigger it offers of lands, time of implantation of the culture, technique accumulated in the production, whereas in the agricultural region of Chapadinha, these indices still are without representation. Moreover, the intensification of the agricultural credit, the agrarian politics and tax incentives are elements that have propitiated increase of the production of the soy. The development of the space circuit and circles of cooperation of the soy, a side, create new forces politics in the Maranhão that can result in the creation of a new state, the other, are responsible, for the elimination of part of the subsistence agriculture, producing social problems as, agrarian concentration and unemployment. The study it still evidences the appropriation of the place for a small number of companies that has generated, beyond an intense concentration of income, an alienation of the territory, in view of that this is used for a strange purpose to the place and the yearning of the population does not stop

Por ser de grande importância o conhecimento de valores séricos referenciais do mineralograma e do proteinograma, a sua utilização na medicina veterinária, e a escassez de trabalhos brasileiros relacionados à espécie caprina, este estudo objetivou determinar e comparar os níveis séricos de cálcio, fósforo, sódio, potássio e proteínas (proteína total, albumina, globulina e a relação albumina/globulina) em caprinos fêmeas da raça Parda Alpina, em três idades diferentes. Foram utilizadas 30 fêmeas caprinas da raça Parda Alpina criadas em regime intensivo, sendo separadas em três grupos: Grupo 1 - 10 fêmeas jovens com idade de quatro meses; Grupo 2 - 10 fêmeas adultas jovens com idade de 18 meses; Grupo 3 - 10 fêmeas adultas lactantes com idade de 24 a 60 meses. Os animais foram avaliados por meio de exames clínico e coproparasitológico. Foram encontrados os seguintes valores médios de cálcio, fósforo, sódio e potássio no grupo G1: 10,10± 1,70, 10,13± 2,04, 151± 3,30 e 5,16± 0,41; no grupo G2: 10,36± 0,94, 7,49± 1,34, 145,9± 3,35 e 4,56± 0,48; e para o grupo G3: 9,47± 1,45, 5,90± 1,21, 153,3± 5,17 e 4,20± 0,55. Para as variáveis proteína total sérica, albumina, globulina e relação albumina/globulina foram encontrados os seguintes valores médios, para o grupo G1: 6,29± 0,94, 3,5± 10,41, 2,78± 0,95 e 1,40± 0,48; para o grupo G2: 7,27± 0,73, 4,92± 1,06, 3,06± 0,56, 1,43± 0,44; e para o grupo G3: 7,14± 0,84, 3,70± 0,20, 3,44± 0,79 e 1,14± 0,30. A análise estatística dos dados demonstra que existe influência da faixa etária nas variáveis fósforo, sódio, potássio, proteína total e albumina.

Background: Interest in folliculogenesis has grown extensively in recent years. Nevertheless, several aspects of follicular activity are still poorly understood. Thus, in vitro culture of ovarian follicles using new substances has been established as a very viable model, enhancing the prospects for a better understanding of follicular activity. Among the family members of the fibroblast growth factor (FGFs), FGF-10 has received recent attention for its ability to regulate the development of ovarian follicles and oocyte maturation. Given the relevance of FGF-10 in the folliculogenesis process, this review aimed to describe the structural features, expression and the main biological effects of FGF-10 on the development of ovarian follicles in mammals.Review: Along this work, it was shown aspects related to structural characterization of FGF-10 and its receptors, as well as FGF-10 expression in different cell types, emphasizing its importance to follicular development. FGF-10 is a paracrine member of the family of FGFs, and is characterized by promoting biological responses via cell surface receptors (FGFRs) of tyrosine kinase-type. of these receptors, FGFR-1, FGFR-2 and FGFR-3 may undergo alternative transcriptional arrangements, enabling the formation of two isoforms (b and c) that have varying degrees of affinity for the various FGFs. Thus, seven FGFR proteins (FGFRs 1b, 1c, 2b, 2c, 3b, 3c and 4) with different binding specificities are generated from the four FGFR genes. The FGFRs transmit intracellular signals after binding with the ligand through the phosphorylation of tyrosine, which activates various transduction patterns in the cytoplasm. The signal transduction of FGF-10 may occur through three main pathways: protein of rat sarcoma (Ras)/MAPK, PLC gamma/Ca(2+) and phosphatidylinositol-3 kinase (PI3K)/protein kinase B (Akt), which are involved in the transmission of biological signals, leading to cellular proliferation and differentiation. FGF-10 mRNA expression was detected in the ovarian stroma, oocyte and theca cells of preantral and antral follicles. on the other hand, the expression of mRNA for FGF-10 receptors was found in, granulosa cells, theca cells, cumulus cells and oocytes. Although FGFs are widely distributed in different tissues and cell types, the importance and function of FGFs in the ovary are still poorly documented. FGF-10 has been shown to be an important mediator of mesenchymal and epithelial cell interactions during follicle development, promoting follicular survival, activation and growth. Besides the action on folliculogenesis, FGF-10 was recently identified as a growth factor able to improve oocyte competence. However, in antral follicles, the presence of FGF-10 is associated with increased follicular atresia, which matches its anti-estrogenic action.Discussion: From this review, we can conclude that FGF-10 is an important regulator of female reproduction. This growth factor acts in follicle survival, oocyte maturation, expansion of cumulus cells and proliferation of granulosa/theca cellsthrough direct and/or indirect actions in the control of folliculogenesis. Furthermore, FGF-10 seemed to have different effects throughout the follicular development. However, it is necessary to perform additional studies that may provide a better understanding about the importance of FGF-10 during folicullogenesis.

OBJETIVO: Verificar se as concentrações de glicose e insulina em jejum são reguladas pela aptidão cardiorrespiratória (VO2máx), independentemente dos efeitos genéticos. MÉTODOS: Dados de 38 pares de gêmeos monozigóticos (11 a 18 anos) foram analisados transversalmente. Os participantes foram submetidos a um teste de esforço máximo com ergoespirometria aberta (MedGraphics VO2000® - Medical Graphics Corp., St. Paul, MN) e à coleta de sangue para estimar a concentração de glicose e insulina em jejum. A zigosidade foi determinada por intermédio da investigação de concordância dos gêmeos em relação a 15 marcadores genéticos polimórficos. Nove pares demonstraram diferença média intrapar para o consumo máximo de oxigênio ≥10mL.kg-1.min-1 e foram divididos em dois grupos, de alta e baixa aptidão. Os grupos foram comparados a partir do teste pareado de Wilcoxon, tendo em vista a assimetria dos dados. RESULTADOS: em média, os gêmeos do grupo de alta aptidão apresentaram consumo máximo de oxigênio 17% superior (13,5±3,7mL.kg-1.min-1) a seus irmãos menos aptos. Não houve diferença entre os grupos para as concentrações de insulina (36,5±34,6 versus 25,3±13,7mg/dL; p<0,813), porém, os gêmeos mais aptos demonstraram menor concentração de glicose do que seus contrapares menos aptos (82,9±7,3 versus 86,7±7,6mg/dL; p<0,010). CONCLUSÕES: Neste estudo, caracterizado como caso-controle (gêmeos monozigóticos discordantes), o irmão com menor aptidão cardiorrespiratória apresentou maior concentração de glicose em jejum, sugerindo que a baixa aptidão cardiorrespiratória está associada a distúrbios no metabolismo de glicose.
