Factors associated with the prevalence of hypertension and control practices among elderly residents of São Paulo city, Brazil

The aim of this study was to analyze the prevalence of hypertension and control practices among the elderly. The survey analyzed data from 872 elderly people in São Paulo, Brazil, through a cluster sampling, stratified according to education and income. A Poisson multiple regression model checked for the existence of factors associated with hypertension. The prevalence of self-reported hypertension among the elderly was 46.9%. Variables associated with hypertension were self-rated health, alcohol consumption, gender, and hospitalization in the last year, regardless of age. The three most common measures taken to control hypertension, but only rarely, are oral medication, routine salt-free diet and physical activity. Lifestyle and socioeconomic status did not affect the practice of control, but knowledge about the importance of physical activity was higher among those older people with higher education and greater income. The research suggests that health policies that focus on primary care to encourage lifestyle changes among the elderly are necessary.

Produção de anticorpo monoclonal reativo com leveduras do gênero candida

The aim of this study was to obtain a reactive monoclonal antibody against Candida albicans. Spleen celIs of BALB/c mice previously immunized withCandida were fused in vitro with mielorna cells Sp2-0Ag14. The resultant hybridcells were kept in culture medium at 5% C02.The suspension growing cells were tested by ELISA to check the antibodies titer. The positive colonies were cloned to achieve the monoclonal antibody and further expanded in mice peritoneum. The antibody produced was purified and isotope. The monoclonal antibody was denominated 76C. The 76C was directed against mannoprotein molecules from Candida cell surface, which has not yet been completely investigated to find outlhe specific nature of epitope. The antibody 76C was analyzed by DOT BLOTagainst different Candida species and there were positives results in 87,5% of the tested samples_ The monoclonal antibody 76C will be a useful tool to investigate oligomannoside epitope from mannan and could be applied in sera diagnosis in invasive candidiasis and in studies of glicidic epitope.

Planejamento, síntese e avaliação da capacidade de doação de óxido nítrico de novos derivados antiinflamatóios

A formação do trombo arterial, composto predominantemente por plaquetas, se dá sob condições de estresse de cisalhamento elevado, nos locais de lesão aterosclerótica vascular e fluxo sanguíneo perturbado e tem como consequência diminuição ou obstrução do calibre dos vasos dos diferentes órgãos podendo levar a eventos isquêmicos. As doenças cardiovasculares são consideradas as principais causas de morte no mundo. Nesse contexto, estima-se que a aterosclerose/aterotrombose seja a causa primária de doença arterial coronariana e acidente vascular cerebral representado mais de 50% das causas de mortes em países ocidentais . É sabido que a aterosclerose, primeiro evento que predispõe à aterotrombose, é considerada um processo inflamatório crônico, e que a utilização de antiinflamatórios não esteroidais (AINEs) COX-1, melhor estabilizam a estrutura da placa ateromatosa impedindo o rompimento e a consequente formação do trombo. Neste contexto, no presente trabalho foram obtidos de novos candidatos a fármacos com propriedades doadoras de NO e antiagregantes plaquetárias, através da estratégia de hibridação molecular dos AINEs contendo uma subunidade doadora de óxido nítrico, representada pelos furoxanos, e espaçada por uma subunidade N-acil hidrazônica. Dessa forma, a inibição da síntese de tromboxanos associada à doação de óxido nítrico permitiu atuação nas plaquetas através de um mecanismo múltiplo de ação com fins de diminuição da agregação plaquetária. Os produtos intermediários e finais apresentaram bons rendimentos e foram caracterizados por técnicas analíticas as quais predisseram que as estruturas propostas foram obtidas. Todos os compostos se como doadores de óxido nítrico. Os compostos 1a e 3a apresentaram atividade analgésica superior a dipirona, utilizada como controle. No ensaio de agregação plaquetária ―in vitro‖... (Resumo completo, clicar acesso eletrônico abaixo)

Dinâmica de rotação de exoplanetas tipo terrestre com perturbação de terceiro corpo

In this work we study some topics of Celestial Mechanics, namely the problem of rigid body rotation and “spin-orbit” resonances. Emphasis is placed on the problem formulation and applications to some exoplanets with physical parameters (e.g. mass and radius) compatible with a terrestrial type constitution (e.g. rock) belonging to multiple planetary systems. The approach is both analytical and numerical. The analytical part consists of: i) the deduction of the equation of motion for the rotation problem of a spherical body with no symmetry, disturbed by a central body; ii) modeling the same problem by including a third-body in the planet-star system; iii) formulation of the concept of “spin-orbit” resonance in which the orbital period of the planet is an integer multiple of the rotation’s period. Topics of dynamical systems (e.g. equilibrium points, chaos, surface sections, etc.) will be included at this stage. In the numerical part simulations are performed with numerical models developed in the previous analytical section. As a first step we consider the orbit of the planet not perturbed by a third-body in the star-planet system. In this case the eccentricity and orbital semi-major axis of the planet are constants. Here the technique of surface sections, widely used in dynamical systems are applied. Next, we consider the action of a third body, developing a more realistic model for planetary rotation. The results in both cases are compared. Since the technique of disturbed surface sections is no longer applicable, we quantitatively evaluate the evolution of the characteristic angles of rotation (e.g. physical libration) by studying the evolution of individual orbits in the dynamically important regions of phase space, the latter obtained in the undisturbed case

O poético alinhave de Murilo Mendes: o poeta, a musa e a metapoesia em As Metamorfoses

Lying under the contribution of a display of characteristics with multiple meanings (Catholicism, Surrealism, unite of contraries, and the dialogue with other types of art), Murilo Mendes focalizes some subjects that are made to become appealing in his works. Some of these subjects appear in his 1945’s poetry book, As metamorfoses, the object of analysis in this present work: the poet’s figure, insert in the historical view of the World War II and by the poet devastated; the muse’s figure, carrier of the sacred and the profane, whose body represents a repository of descriptions with surrealistic meanings, that is shown indistinctly as the poetry itself; and, concluding, the poetry (or the metapoetry) expressed in this context (historical and literary). Therefore, we intend to search, based in the analysis of poems, how each of this instances are configured inside the poetic universe of Murilo Mendes, with the intention of enlighten the constitution of the sewing made of them by the poet from Juiz de Fora; instances that are very precious when we deal with the poetry that gives to his writings the patent feature of modernity.

Plasmacytoma in the oral cavity: a case report

The plasma cell neoplasms may present in soft tissue as extramedullary plasmacytoma (EMP), in bone as a solitary plasmacytoma of bone (SPB), or as part of the multifocal disseminated disease multiple myeloma (MM). The EMP is rare, comprising around 3% of all plasma cell neoplasm. The majority (80%) occurs in the head and neck region. In this study we report a case of a man, 70 years old, melanoderm, with a lesion of the oral cavity. Upon physical examination, a lesion was found that extended throughout the posterior upper alveolar ridge, as far as the maxillary tuber on the left side, extending towards the palate. Radiographic examination, complementary laboratory exams were performed. Based on the conclusive symptoms of plasmacytoma, the patient was referred to the hematology service for treatment with local radiotherapy. The patient responded satisfactorily to the treatment, and after 15 months, all clinical symptoms of the lesion in the oral cavity had disappeared.

De Flaubert para Maupassant

This article aims to present some reflections about a selection of letters that Gustave Flaubert (1821-1880) wrote to Guy de Maupassant (1850-1893), between September 23, 1872 and May 3, 1880. For eight years, Flaubert was Maupassant’s friend and a literary master and his letters, marked by a multiple and disordered discourse, reveal a path to friendship and the passionate dedication of the master regarding the intellectual and artistic development of the young writer. It is intended here, to draw some considerations to the moments when Flaubert’s speech assumes, directly or indirectly, a pedagogical role and the letter becomes a way to literary teaching.

Suplementos múltiplos para novilhas de corte a pasto no período seco: características nutricionais

The objective was to evaluate levels of multiple supplements supplied to beef heifers in low supply of pasture on intake and nutrients digestibility, pH and concentration of ruminal ammonia nitrogen, nitrogen balance, synthesis and microbial efficiency. Five Nellore heifers with initial body weight of 344.00 +/- 21.10 kg and average initial age of 22 months were used. The following supplements were evaluated as fed to the animals: control (mineral supplement) and supplementation levels of 2, 4, 6 and 8 kg/animal/day, composing the following percentages of body weight (BW): 0.55, 1.11, 1.66 and 2.22%, respectively. The experimental design was a Latin square with five replications and five supplements. Intakes of total dry matter, crude protein (CP) and total digestible nutrients, and total apparent digestibility of dry matter, crude protein, total carbohydrates and no fiber carbohydrates increased linearly (P <0.0001) and dry matter intake of forage decreased (P <0.0001) with supplementation levels. Supplementation strategies promoted reduction on ruminal pH (P = 0.0343) and increased concentration of ruminal ammonia nitrogen (NH3-N) (P = 0.0004) before the supply of supplements, and after, this NH3-N presented quadratic behavior (P = 0.0023). Nitrogen intake, excretion of urea in urine and nitrogen excretion in feces increased linearly (P <0.0001) according to supplementation levels. The supply of high levels of multiple supplements reduces forage intake and presents itself as an alternative to cattle maintained in a systems with low supply of pasture in the dry season.
