Abstract: purpose: the aim of this study was to evaluate the relaxation in vitro of cavernous smooth muscle induced by a new no donor of the complex nitrosil-ruthenium, named trans-[ru(nh3)4(caffeine)(no)]c13 (rut-caf) and sodium nitroprusside (snp). materials and methods: the tissues, immersed in isolated bath systems, were pre-contracted with phenilephrine (pe) (1 μm) and then concentration-response curves (10-12 - 10-4 m) were obtained. to clarify the mechanism of action involved, it was added to the baths odq (10 μm, 30 μm), oxyhemoglobin (10 μm), l-cysteine (100 μm), hydroxicobalamine (100 μm), glibenclamide, iberotoxin and apamine. tissue samples were frozen in liquid nitrogen to measure the amount of cgmp and camp produced. results: the substances provoked significant relaxation of the cavernous smooth muscle. both rut-caf and snp determined dose-dependent relaxation with similar potency (pec50) and maximum effect (emax). the substances showed activity through activation of the soluble guanylyl cyclase (sgc), because the relaxations were inhibited by odq. oxyhemoglobin significantly diminished the relaxation effect of the substances. l-cysteine failed to modify the relaxations caused by the agents. hydroxicobalamine significantly diminished the relaxation effect of rut-caf. glibenclamide significantly increased the efficacy of rut-caf (pec50 4.09 x 7.09). there were no alterations of potency or maximum effect of the substances with the addition of the other ion channel blockers. rut-caf induced production of significant amounts of cgmp and camp during the relaxation process. conclusions: in conclusion, rut-caf causes relaxation of smooth muscle of corpus cavernosum by means of activation of sgc with intracellular production of cgmp and camp; and also by release of no in the intracellular environment. rut-caf releases the no free radical and it does not act directly on the potassium ion channels.
DE PROTESTOS E LEVANTES: AS REVOLTAS DA VACINA E DA CHIBATA NA MúSICA POPULAR
Luciana Marino Nascimento,Francisco Bento da Silva
Revista Recorte , 2012,
Abstract: The discussion in this paper turns around the causes, impacts and unfolding of two very meaningful events that took place during the initial period of the Brazilian Republic, in the first decade of the 20th century. These events, whose historiographical production is considerably heterogeneous, were called the Vaccine Insurrection (1904) and the Whip Insurrection (1910). The discussion focus on the analysis of song lyrics composed in the epoch or in subsequent periods. Five lyrics are analyzed: three about the Vaccine Insurrection and two about the Whip Insurrection. The songs about the first insurrection are: Rat, rat (1904); Yellow Fever (1907) and Compulsory Vaccination (1904). The ones about the second insurrection are: The claimers (1910) and The master of ceremonies of the sea (1975).

Abstract: Os estudos sobre ativos intangíveis vêm aumentando significativamente em fun o da relevancia destes ativos para a composi o do valor da empresa. Diante disso o presente trabalho visa dentro desta temática de pesquisa, verificar a correla o existente entre o Grau de Intangibilidade (GI) e os indicadores de desempenho, Giro do Ativo (GA), Margem Líquida (ML), Retorno sobre o Ativo (ROA) e Retorno sobre o Patrim nio Líquido (ROE) das empresas dos setores de tecnologia da informa o e de telecomunica es. A pesquisa classifica-se quanto aos objetivos como descritiva e quanto à abordagem dos dados, como quantitativa. A amostra utilizada foi composta pelas empresas listadas na BOVESPA dos setores de Tecnologia da Informa o (5) e Telecomunica es (12). A análise foi realizada utilizando-se os testes de homogeneidade Qui-quadrado (χ2) e teste Wilcoxon para a verifica o de existência de diferen a entre os setores analisados, e para análise da correla o utilizou-se o coeficiente de correla o. A literatura de forma controversa apresenta resultados contraditórios, indicando a existência de correla o em determinados segmentos e inexistência para outros. Os resultados indicaram n o haver diferen as entre os segmentos analisados e ainda que o giro do ativo n o apresentou uma correla o estatisticamente significativa com os índices de desempenho utilizados, entretanto sugere-se a amplia o da amostra, dada as limita es inerentes à utiliza o de amostras n o-probabilísticas e ainda com tamanho reduzido. Studies about intangible assets have increased significantly due to its relevance to the composition of the company value. Therefore, this study aims to investigate the correlation among Degree of Intangibility (DI), performance indicators, Asset Turnover (AT), Net Margin (NM), Return on Assets (ROA), and Return on Equity (ROE) of companies from information technology sector and telecommunications. This is a descriptive and quantitative survey. The sample was composed by companies listed in BOVESPA belonging to sectors of Information Technology (5) and Telecommunications (12). The analysis was performed using chi-square (χ2) homogeneity tests and ‘Wilcoxon’ test for checking the existence of differences among analyzed sectors; correlation coefficient test was used for correlation analysis. The controversial literature presents inconsistent results, indicating correlation existence in certain segments and no correlation for others. Results showed no differences among the analyzed segments and, even if the asset turnover has not submitted to a statistically signif

Abstract: This is a qualitative study that aims to describe the opinion of nursing students on the use of an educational hypermedia on Peripheral Venipuncture. We interviewed 16 nursing students of a private university on second semester of 2014. The interviews allowed the identification of units of meaning and categorization by content analysis and led to four categories: influence of hypermedia on learning, educational technology as support to teaching classroom, contribution of hypermedia for professional practice and access difficulties. Hypermedia showed positive results as most scholars reported that the material helped in learning and generated autonomy and interactivity in the moment of studying. However some reported difficulties in access hypermedia related mainly to the server used. So hypermedia proved to be a valuable tool to use, since it favored the learning and aroused the interest and curiosity of students.

Abstract: The provision of care by health professionals seems to be related to cultural patterns in which these workers are inserted. The relationship between culture and care becomes a challenge for the provision of health care to homosexual and bisexual population. Thus, this study aimed to identify the perception of Gays, Lesbians, Bisexuals and Transgenders in relation to the care received from health professionals, in the light of Cross-Cultural Theory. This is a qualitative, ethnographic study, conducted with 30 members of sexual minorities in Juazeiro do Norte, Brazil. The data analysis lead to the elaboration of five categories based on of the Theory of Cultural Care Diversity and Universality. The participants emphasized the constant violation of their rights to universal and equitable access to the National Health System, stating that they have suffered from prejudice and exclusion, as result of a heteronormative culture. They highlighted that homophobia and dehumanization of care have a strong relation to sexual orientation. The transvestites are the most prone to humiliation and pejorative attitudes of professionals and such condition is a barrier to accessing services.

Abstract: The objective of this study was to evaluate the effect of reducing the spacing on the yield and components of grain yield and other agronomic traits of maize hybrids of second harvest (popular safrinha in Brazil) in the cerrado (vegetation of the Brazilian interior) of Mato Grosso do Sul. The experiment was conducted at the State University of Mato Grosso do Sul - University Unit of Aquidauana, MS, being classified as soil Acrisol. The experimental design used was randomized complete block in factorial scheme (7 x 2), with four replicates. The treatments were composed by combinations of two spaces (0.45 and 0.90 m) and seven hybrids of corn (AG 8088, AG 9040, CD 308, 2B587, Fórmula, DG 501 and BG 7049). Were performed for all hybrids, the measurement of plant height, height of insertion of the first cob and thatched diameter, in addition to the number of rows per ear, grains per spike, 1000 grain mass (g), diameter, length and productivity. The results indicate that there is no interaction between the spaces and the hybrids and 0.45 m spacing there was an increase in the number of grains per spike, stem diameter, stem length and productivity.O objetivo deste estudo foi avaliar o efeito da redu o do espa amento entre linhas sobre o rendimento e componentes do rendimento de gr os e sobre outras características agron micas de híbridos de milho de segunda safra (popular safrinha) no cerrado de Mato Grosso do Sul.
