Aquest procés ha tingut una durada de 17 mesos però en el present treball es desenvolupen, específicament, els últims mesos on hi ha hagut una participació més directe i vinculant

Vozes d'África Transatlântica: trajetórias estudantis de Cabo Verde e da Guiné-Bissau - programa de estudantes - convénio de graduação

A presente investigação tem como centralidade a mobilidade internacional de estudantes no caso, a dos africanos oriundos de Cabo Verde e da Guiné-Bissau, participantes do Programa Estudantes-Convênio de Graduação na Universidade Federal do Rio Grande do Norte - UFRN, inserida no fenômeno da internacionalização universitária, acentuada na globalização. O objetivo principal foi analisar o processo de inserção social e acadêmica desses estudantes, com ênfase para os dos cursos de Arquitetura e Urbanismo, Ciências da Computação, Engenharia da Computação e Medicina, nessa Instituição de Ensino Superior - IES. A metodologia foi norteada pela conjugação dos aportes teóricos e metodológicos qualiquantitativa, em que, na primeira, utilizou-se da entrevista semiestrutura dirigida para dezesseis sujeitos; sendo, a metade estudantes e a outra docentes, cuja análise optou-se pela Análise de Discurso (AD) da linha francesa, resultando as formações discursivas: motivações da mobilidade, registro nacional de estrangeiro, identidade étnica, relações étnicoraciais e o PEC-G: seu funcionamento nas práticas sociais na UFRN. Já a pesquisa quantitativa, foi constituída pela aplicação do questionário para o universo de 40 estudantes dos dois grupos e de todas as áreas de conhecimento, cuja interpretação dos dados, recorreu-se ao Programa SPSS. Já, para o recorte dos cursos específicos, foi utilizado, o do Google Doc, os quais, estão expressos em tabelas e gráficos. Os resultados revelaram que essa mobilidade estudantil africana está imersa por um misto de semelhanças e diferenças entre o Brasil e dos Países Africanos de Língua Oficial Poruguesa - PALOP; e mais dos contextos das hierarquias entre os países centrais, semiperiféricos e periféricos, provocadas pelas políticas de reajustes estruturais sobre os serviços educacionais, Sousa (Santos 2008; 2010), que se refletem nas trajetórias acadêmicas temporária no país de acolhimento. Aqui, também, enfrenta as fragilidades e os avanços das políticas públicas do Sistema de Ensino Superior, implementadas pelo governo brasileiro nas IES. Em termos quantitativos para os quatros cursos analisados, em diferentes e curtos períodos, quanto a distribuição de vagas (acesso), formas de desligamentos e conclusão apontaram especificidades. E, grosso modo, o curso de Medicina, apresentou os melhores índices de conclusão, seguidos, pelos de Arquitetura e da Engenharia da Computação. A maioria dos estudantes são do sexo masculino, mais da metade está representada pelos oriundos de Cabo Verde, o restante, pelos da Guiné-Bissau. Enquanto, no curso de Ciências da Computação, foi nula a conclusão de curso, e em função deste histórico de baixo desempenho dos estudantes-convênio PEC-G, teria havido o fechamento de vagas. Mas, verificando-se, que os índices de conclusão nesses cursos, apresentou uma média abaixo dos cursos de graduação da UFRN, nos quais, esses estudantes são minoria ao lado dos afrobrasileiros nas universidades do Brasil.

Sentencia de la Corte Constitucional del Ecuador sobre la constitucionalidad de la obligación del afianzamiento tributario (Jurisprudencia)

Los sujetos pasivos que impugnen ante la vía judicial un acto administrativo mediante el cual se pretenda determinar o recaudar tributos, deben rendir una caución equivalente al 10% de la cuantía de su demanda, de no presentársela en el término de quince días, el acto impugnado queda ejecutoriado y los jueces deben ordenar el archivo del proceso. Nuestra Corte Constitucional para el Período de Transición considera que no se vulnera derecho alguno en ese caso, siempre y cuando se exija rendir la caución después de calificada la demanda. Estudiaremos los fundamentos que tuvo la Corte Constitucional para llegar a esa conclusión. Pretenderemos analizarlos y cuestionarlos objetivamente, para así demostrar por qué su falta de coherencia y de sustento permite concluir que su análisis pecó por falto de imparcialidad, y por qué es razonable suponer que sus móviles no fueron jurídicos en lo absoluto, sin perjuicio de que, a la par, demos nuestro parecer al respecto. Independientemente de la trascendencia jurídica que puedan o no tener en nuestro ordenamiento, esperamos se entienda por qué creemos que estos precedentes deben ser considerados como un capítulo funesto en la historia de la jurisprudencia constitucional ecuatoriana.

How was patient empowerment portrayed in information leaflets describing the community pharmacy Medicines Use Review service in the UK?

Objective The Medicines Use Review (MUR) community pharmacy service was introduced in 2005 to enhance patient empowerment but the service has not been taken up as widely as expected. We investigated the depiction of the patient–pharmacist power relationship within MUR patient information leaflets. Methods We identified 11 MUR leaflets including the official Department of Health MUR booklet and through discourse analysis examined the way language and imagery had been used to symbolise and give meaning to the MUR service, especially the portrayal of the patient–pharmacist interactions and the implied power relations. Results A variety of terminology was used to describe the MUR, a service that aimed ultimately to produce more informed patients through the information imparted by knowledgeable, skilled pharmacists. Conclusion The educational role of the MUR overshadowed the intended patient empowerment that would take place with a true concordance-centred approach. Although patient empowerment was implied, this was within the boundaries of the biomedical model with the pharmacist as the expert provider of medicines information. Practice implications If patient empowerment is to be conveyed this needs to be communicated to patients through consistent use of language and imagery that portrays the inclusivity intended.

Educational and psychosocial programmes for adolescents with diabetes: approaches, outcomes and cost-effectiveness

Diabetes incurs heavy personal and health system costs. Self-management is required if complications are to be avoided. Adolescents face particular challenges as they learn to take responsibility for their diabetes. A systematic review of educational and psychosocial programmes for adolescents with diabetes was undertaken. This aimed to: identify and categorise the types of programmes that have been evaluated; assess the cost-effectiveness of interventions; identify areas where further research is required. Sixty-two papers were identified and Subjected to a narrative review. Generic programmes focus on knowledge/skills, psychosocial issues, and behaviour/self-management. They result in modest improvements across a range of outcomes but improvements are often not sustained, suggesting a need for continuous support, possibly integrated into normal care. In-hospital education at diagnosis confers few advantages over home treatment. The greatest returns may be obtained by targeting poorly controlled individuals. Few studies addressed resourcing issues and robust cost-effectiveness appraisals are required to identify interventions that generate the greatest returns on expenditure.

Pharmacological analysis of a dopamine D-2Short: G(alpha o) fusion protein expressed in Sf9 cells

A dopamine D-2Short receptor:G(alphao) fusion protein was expressed in Sf9 cells using the baculovirus expression system. [H-3]Spiperone bound to D-2Short:G(alphao) with a pK(d) approximate to 10. Dopamine stimulated the binding of [S-35]guanosine-5'-O-(3-thio)triphosphate (GTPgammaS) to D-2Short:G(alphao) expressed with Gbeta(1)gamma(2) (E-max > 460%; pEC(50) 5.43 +/- 0.06). Most of the putative D-2 antagonists behaved as inverse agonists (suppressing basal [S-35]GTPgammaS binding) at D-2Short:G(alphao)/Gbeta(1)gamma(2) although (-)-suipiride and ziprasidone were neutral antagonists. Competition of [H-3]spiperone binding by dopamine and 10,11-dihydroxy-N-n-propylnorapo-morphine revealed two, binding sites of different affinities, even in the presence of GTP (100 muM). The D-2Short:G(alphao) fusion protein is therefore a good model for characterising D-2 receptors.

Expressing medicine side effects: assessing the effectiveness of absolute risk, relative risk, and number needed to harm, and the provision of baseline risk information

Objective: To assess the effectiveness of absolute risk, relative risk, and number needed to harm formats for medicine side effects, with and without the provision of baseline risk information. Methods: A two factor, risk increase format (relative, absolute and NNH) x baseline (present/absent) between participants design was used. A sample of 268 women was given a scenario about increase in side effect risk with third generation oral contraceptives, and were required to answer written questions to assess their understanding, satisfaction, and likelihood of continuing to take the drug. Results: Provision of baseline information significantly improved risk estimates and increased satisfaction, although the estimates were still considerably higher than the actual risk. No differences between presentation formats were observed when baseline information was presented. Without baseline information, absolute risk led to the most accurate performance. Conclusion: The findings support the importance of informing people about baseline level of risk when describing risk increases. In contrast, they offer no support for using number needed to harm. Practice implications: Health professionals should provide baseline risk information when presenting information about risk increases or decreases. More research is needed before numbers needed to harm (or treat) should be given to members of the general populations. (c) 2005 Elsevier Ireland Ltd. All rights reserved.

The Usefulness of Caries Frequency, Depth, and Location in Determining Cariogenicity and Past Subsistence: A Test on Early and Later Agriculturalists From the Peruvian Coast

Dental markers have been used to unravel particularities of paleodiet, subsistence, social structure, and health. This article aims to compare oral pathology among four pre-Columbian groups with different degrees of agricultural and socio-cultural development but comparable ecological conditions who lived on the coastal desert of Peru. Three of these groups are assigned to distinct phases of the Formative Period (2500-1 BC), a time critical for our understanding of the development of agriculture and social complexity. The fourth group corresponds to the Late Intermediate Period (1000-1470 AD), when agriculture had its apogee and society was highly stratified. In this study we test whether there is an increase (1) in the frequency of carious lesions and (2) in caries depth, and (3) if there is a shift from occlusal to extra-occlusal caries locations with the development of agriculture. Therefore, we analyze the frequencies of carious lesions and antemortem tooth loss (AMTL), the caries distributions by age, sex, and type of tooth, as well as the tissues affected by, and the location of the carious lesions. Since there are no significant differences in the frequencies of carious lesions and AMTL between the groups, we reject hypothesis 1. In contrast, caries depth does increase, and caries location changes from occlusal to extra-occlusal sites with agricultural development. However, we can only corroborate hypothesis 2 and 3 when taking into consideration dental wear. Thus, we recommend that caries depth and locations should be used with evaluations of dental wear to reconstruct subsistence in ancient populations. Am J Phys Anthropol 143:75-91, 2010.

Small mammals of the mid-Araguaia River in central Brazil, with the description of a new species of climbing rat

The mid-Araguaia River basin in central Brazil is considered a priority area for biodiversity conservation, and Parque Estadual do Cantao (PEC) is one of the most important protected areas in this ecotone between Cerrado and Amazonia. This area suffers an intensive human pressure with high rates of deforestation, and still remains poorly studied in terms of biodiversity. From June 2007 to November 2008 we sampled small mammals from both banks of the mid-Araguaia River, in the states of Tocantins and Para. Data are given about morphological traits, geographic distribution and natural history of 22 species of small non-volant mammals (eight marsupials and 14 rodents) surveyed at PEC and its surroundings. We also present mitochondrial phylogenetic analyses that allow species identification within the genera: Oecomys, Oligoryzomys and Rhipidomys, and delineate an undescribed species of Thrichomys. Based on morphologic and molecular data, we describe a new species of Rhipidomys previously assigned to R. nitela, which is apparently endemic to the Araguaia-Tocantins basin in the Cerrado. Additionally, our phylogenetic analyses provide support for the role played by the Araguaia River as an important geographic barrier for two sister species of Rhipidomys.

Role of a Novel Tetrodotoxin-Resistant Sodium Channel in the Nitrergic Relaxation of Corpus Cavernosum from the South American Rattlesnake Crotalus Durissus Terrificus

Introduction. Coitus in snakes may last up to 28 hours; however, the mechanisms involved are unknown. Aim. To evaluate the relevance of the nitric oxide (NO)-cyclic guanosine monophosphate (cGMP)-phosphodiesterase type 5 (PDE5) system in snake corpus cavernosum reactivity. Methods. Hemipenes were removed from anesthetized South American rattlesnakes (Crotalus durissus terrificus) and studied by light and scanning electronic microscopy. Isolated Crotalus corpora cavernosa (CCC) were dissected from the non-spiny region of the hemipenises, and tissue reactivity was assessed in organ baths. Main Outcome Measures. Cumulative concentration-response curves were constructed for acetylcholine (ACh), sodium nitroprusside (SNP), 5-cyclopropyl-2-[1-(2-fluorobenzyl)-1H-pyrazolo[3,4-b]pyridine-3-yl]pyrimidin-4-ylamine (BAY 41-2272), and tadalafil in CCC precontracted with phenylephrine. Relaxation induced by electrical field stimulation (EFS) was also done in the absence and presence of N omega nitro-L-arginine methyl ester (L-NAME; 100 mu M), 1H-[1, 2, 4] oxadiazolo[4,3-a]quinoxalin-1-one (ODQ; 10 mu M) and tetrodotoxin (TTX; 1 mu M). Results. The hemipenes consisted of two functionally concentric corpora cavernosa, one of them containing radiating bundles of smooth muscle fibers (confirmed by alpha-actin immunostaining). Endothelial and neural nitric oxide synthases were present in the endothelium and neural structures, respectively; whereas soluble guanylate cyclase and PDE5 were expressed in trabecular smooth muscle. ACh and SNP relaxed isolated CCC, with the relaxations being markedly reduced by L-NAME and ODQ, respectively. BAY 41-2272 and tadalafil caused sustained relaxations with potency (pEC(50)) values of 5.84 +/- 0.17 and 5.10 +/- 0.08 (N = 3-4), respectively. In precontracted CCC, EFS caused frequency-dependent relaxations that lasted three times longer than those in mammalian CC. Although these relaxations were almost abolished by either L-NAME or ODQ, they were unaffected by TTX. In contrast, EFS-induced relaxations in marmoset CC were abolished by TTX. Conclusions. Rattlesnake CC relaxation is mediated by the NO-cGMP-PDE5 pathway in a manner similar to mammals. The novel TTX-resistant Na channel identified here may be responsible for the slow response of smooth muscle following nerve stimulation and could explain the extraordinary duration of snake coitus.

Relative entropy measures applied to healthy and pathological voice characterization

Nowadays, noninvasive methods of diagnosis have increased due to demands of the population that requires fast, simple and painless exams. These methods have become possible because of the growth of technology that provides the necessary means of collecting and processing signals. New methods of analysis have been developed to understand the complexity of voice signals, such as nonlinear dynamics aiming at the exploration of voice signals dynamic nature. The purpose of this paper is to characterize healthy and pathological voice signals with the aid of relative entropy measures. Phase space reconstruction technique is also used as a way to select interesting regions of the signals. Three groups of samples were used, one from healthy individuals and the other two from people with nodule in the vocal fold and Reinke`s edema. All of them are recordings of sustained vowel /a/ from Brazilian Portuguese. The paper shows that nonlinear dynamical methods seem to be a suitable technique for voice signal analysis, due to the chaotic component of the human voice. Relative entropy is well suited due to its sensibility to uncertainties, since the pathologies are characterized by an increase in the signal complexity and unpredictability. The results showed that the pathological groups had higher entropy values in accordance with other vocal acoustic parameters presented. This suggests that these techniques may improve and complement the recent voice analysis methods available for clinicians. (C) 2008 Elsevier Inc. All rights reserved.
