Projeto social, esporte e educação: a produção da identidade no ensino do taekwondo / Social project, sport and education: the production of identity in teaching taekwondo / Proyecto social, deporte y educación: la producción de la identidad en la enseñanza del taekwondo

Por meio de algumas noções conceituais produzidas no campo dos Estudos Culturais e entrevistas narrativas com participantes de um projeto social de ensino do Taekwondo, vinculado ao Programa Escola da Família, analisamos como projetos desse tipo influenciam na vida de jovens em situação de vulnerabilidade social. Consideramos que tais projetos produzem identidades e impactam as subjetividades dos jovens atendidos, quando estes não se adéquam aos discursos hegemônicos de classe social, gênero, saúde e educação; contribuem para que crianças e jovens permaneçam à margem da sociedade em que se encontram e, por consequência, favorecem a promoção de políticas que os mantém tutelados pelo Estado.

Through some conceptual notions produced in the field of Cultural Studies and narrative interviews with participants from the social project the teaching of Taekwondo linked to the Escola da Família Program, we analyzed how projects of this type influence the lives of young people in situations of social vulnerability. We consider that projects like this impact the subjectivities of the young people who is inside the project, when they are not adapted to the hegemonic discourses of social classes, gender, health and education; they help children and young people to remain on the margins of the society in which they find themselves and, consequently, favoring the promotion of policies that keep them under the tutelage of the State.

Consideramos que proyectos como este impactan las subjetividades de los jóvenes atendidos, cuando no se adaptan a los discursos hegemónicos de clase social, género, salud y educación; ayudan a los niños, niñas y jóvenes a permanecer al margen de la sociedad en la que se encuentran y, en consecuencia, favorecen la promoción de políticas que los mantengan bajo la tutela del Estado.

Currículo cultural: outras possibilidades de pensar a ressignificação / Cultural curriculum: other possibilities of thinking about resignification / Currículo cultural: otras posibilidades de pensar la resignificación

Resumo Neste artigo, apresentamos o modo como o encaminhamento didático-metodológico do Currículo Cultural da Educação Física denominado ressignificação emerge nas aulas do componente e alguns de seus possíveis efeitos nos modos de subjetivação dos discentes. Por meio de uma autoetnografia, produzimos um relato de prática pedagógica, o qual analisamos com base no quadro teórico que ancora essa perspectiva curricular e nas noções de governamentalidade e contraconduta desenvolvidas por Michel Foucault. Notamos que a ressignificação desponta nas ações de resistência promovidas pelos discentes em relação aos modos de regulação das aulas e da prática corporal em estudo. Visto que essas resistências possibilitaram aos discentes elaborarem ações de contraconduta. Um processo que possibilitou outras conduções de si, do outro, assim como diferentes formas de ser, viver e pensar sobre a prática corporal em estudo, potencializando práticas de liberdade. (AU)

Abstract In this article, we present in which way the didactic-methodological proceeding of the Cultural Curriculum of Physical Education called resignification emerges, and some of its possible effects on the students' modes of subjectivation. By means of an autoethnography, we produced a report of pedagogical practice, which we analyzed based on the theoretical bases that anchors this curricular perspective and the notions of governmentality and counter-conduct elaborated by Michel Foucault. We noticed that the resignification emerges in the resistance actions promoted by the participants in relation to the ways of regulating the classes and the corporal practices under study, since these allow students to elaborate counter-conduct actions. A process that made possible other conducts of self, of others, as well as different ways of being, living and thinking about the corporal practices under study, potentiating practices of freedom.

Diversification of Amazonian spiny tree rats in genus Makalata (Rodentia, Echimyidae): Cryptic diversity, geographic structure and drivers of speciation.

Amazonian mammal diversity is exceptionally high, yet new taxonomic discoveries continue to be made and many questions remain for understanding its diversification through time and space. Here we investigate the diversification of spiny rats in the genus Makalata, whose species are strongly associated with seasonally flooded forests, watercourses and flooded islands. We use a biogeographical approach based on a mitochondrial cytochrome b gene through divergence time estimation and reconstruction of ancestral areas and events. Our findings indicate an ancient origin of Makalata for the Guiana Shield and Eastern Amazonia as ancestral area. A first cladogenetic event led to a phylogeographic break into two broader clades of Makalata through dispersal, implying a pattern of western/Eastern Amazonian clades coinciding with the Purus Arch (middle Miocene). Most of subclades we infer originated between the late Pliocene to the early Pleistocene, with few recent exceptions in the early Pliocene through dispersal and vicariant events. The hypothesis of rivers as dispersal barriers is not corroborated for Makalata, as expected for mammalian species associated with seasonally flooded environments. We identify two key events for the expansion and diversification of Makalata species: the presence of geologically stable areas in the Guiana and Brazilian shields and the transition from lacustrine conditions in western Amazonia (Acre system) to a river system, with the establishment of the Amazon River transcontinental system and its tributaries. Our results are congruent with older geological scenarios for the Amazon basin formation (Miocene), but we do not discard the influence of recent dynamics on some speciation events and, mainly, on phylogeographic structuring processes.

Reversal of itraconazole resistance in Sporothrix brasiliensis and Sporothrix schenckii by nonsteroidal anti-inflammatory drugs / Reversión de la resistencia a itraconazol en Sporothrix brasiliensis y Sporothrix schenckii con antiinflamatorios no esteroideos

Background: The emergence of resistant isolates has brought challenges to the treatment of sporotrichosis, prompting the search for new therapeutic strategies. Previous studies reported that nonsteroidal anti-inflammatory drugs (NSAIDs) show in vitro activity against several pathogenic fungi, including species of Candida, Cryptococcus, and Trichosporon.AimsThis study aimed to investigate the in vitro efficacy of three NSAIDs (acetylsalicylic acid, diclofenac sodium, and ibuprofen), alone and in combination with itraconazole, against eleven clinical isolates of Sporothrix brasiliensis and Sporothrix schenckii.MethodsMinimal inhibitory concentrations were determined by the broth microdilution method. Drug interactions and the fractional inhibitory concentration index of NSAIDs and itraconazole were assessed by the checkerboard method.ResultsWhen used alone, ibuprofen was the most active NSAID, followed by acetylsalicylic acid. Combinations of NSAIDs with itraconazole showed synergistic antifungal activity against nine isolates. It was also found that itraconazole combined with acetylsalicylic acid, diclofenac sodium, or ibuprofen, led to resistance reversal in two, three, and five of the six drug-resistant isolates, respectively. (AU)

Antecedentes: La aparición de cepas resistentes a los antifúngicos convencionales ha supuesto un nuevo desafío en el tratamiento de la esporotricosis y ha impulsado la búsqueda de nuevas estrategias terapéuticas. Estudios anteriores han descrito que los antiinflamatorios no esteroideos (AINE) tienen actividad in vitro contra diversos hongos patógenos, incluidas especies de Candida, Cryptococcus y Trichosporon.ObjetivosEste estudio tuvo como objetivo investigar la eficacia in vitro de tres AINE (ácido acetilsalicílico, diclofenaco sódico e ibuprofeno), aisladamente y en combinación con itraconazol, contra once aislamientos clínicos de Sporothrix brasiliensis y Sporothrix schenckii.MétodosLas concentraciones inhibitorias mínimas fueron determinadas según el método de microdilución en caldo. Las interacciones farmacológicas y el índice de concentración inhibitoria fraccional de los AINE y de itraconazol fueran evaluadas mediante el método del tablero de ajedrez.ResultadosComo molécula única, el ibuprofeno fue el AINE más activo, seguido del ácido acetilsalicílico. Las combinaciones de los AINE con itraconazol exhibieron actividades antifúngicas sinérgicas frente a nueve aislamientos. También se observó que la combinación de itraconazol con ácido acetilsalicílico, diclofenaco sódico o ibuprofeno provocó la reversión de la resistencia en dos, tres y cinco de los seis aislamientos resistentes a los fármacos, respectivamente.

Skull images were the most prevalent (51.8%). The CVI obtained by the experts' validation in the first round resulted in an agreement of 98% and in the second round, after descriptive suggestions, obtained a CVI of 100%. Final considerations: In view of the data obtained through the selected methodology, there was the construction and validation of the care protocol for the elderly submitted to computed tomography.

Clinical Course of Patients Undergoing Myocardial Revascularization Surgery in a Public Cardiology Referral Hospital in Pará, Brazil

Myocardial revascularization surgery (MRS) is the most frequently performed cardiac surgery in Brazil. However, data on mortality rates among patients undergoing MRS in hospitals other than the main referral centers in the northern Brazil are scarce. Objective: To describe the clinical course of patients that submitted to MRS in the major public cardiology referral hospital in the Brazilian Amazon. Methods: Retrospective cohort analysis, by review of medical records of patients who had undergone MRS at Hospital das Clínicas Gaspar Vianna (FHCGV) from January 2013 to June 2014. Results: A total of 179 patients were evaluated. Mortality rate was 11.7% until 30 days after surgery. Waiting time for surgery ≥ 30 days (OR 2.59, 95%CI 1.02 - 6.56, p = 0.039), infection during hospitalization (OR 3.28, 95%CI 1.15 - 9.39, p = 0.021) and need for hemodialysis after surgery (OR 9.06 95%CI 2.07 - 39.54, p = 0.001) were predictors of mortality after CABG. Conclusion: A high mortality rate in the study population was found, higher than that reported in the literature and in other regions of Brazil

Electrocardiography scar quantification correlates with scar size of hypertrophic cardiomyopathy seen by multidetector computed tomography

BACKGROUND: Hypertrophic cardiomyopathy (HCM), a genetically transmitted disease, is the most common genetic cardiovascular disease. Current strategies to stratify risk are expensive and concentrated in wealthy centers. Twelve-lead electrocardiography (ECG) is inexpensive, universally available, and can be readily used for Selvester QRS scoring, which estimates scar size. This study aimed to establish the relation between ECG scar quantification and myocardial fibrosis (extent of myocardial delayed enhancement) in multidetector computed tomography (MDCT). HYPOTHESIS: There is a significant association between ECG scar quantification and the extent of myocardial delayed enhancement in MDCT. METHODS: Seventy-five patients with HCM underwent a routine clinical evaluation and echocardiography, 12-lead ECG, and MDCT study. Patients with and without an implantable cardioverter-defibrillator were included. RESULTS: The estimated Selvester QRS score of myocardial fibrosis was correlated significantly (R = 0.70; P < 0.01) with the quantified MDCT fibrosis. Compared with MDCT, the QRS score had 84.8% sensitivity and 88.8% specificity. Myocardial fibrosis was present in 88% of these patients with HCM (fibrotic mass, 9.87 10.8 g) comprising 5.66% 6.16% of the total myocardial mass seen on the MDCT images. The Selvester QRS score reliably predicted the fibrotic mass in 76% of patients, which estimated 8.44% 7.39% of the total myocardial mass. CONCLUSIONS: The Selvester QRS score provides reliable quantification of myocardial fibrosis and was well correlated with MDCT in patients with HCM.

CKD-EPI versus Cockcroft-Gault formula for predicting contrast-induced nephropathy following percutaneous coronary intervention in patients without significant renal impairment. / Fórmula de CKD­EPI versus Cockcroft­Gault na predição de nefropatia induzida por contraste após intervenção coronária percutânea, em pacientes sem disfunção renal significativa.

INTRODUCTION: Individuals with glomerular filtration rate (GFR) ≥60 ml/min/1.73 m2 estimated by the Cockcroft-Gault formula (CG) who undergo percutaneous coronary intervention (PCI) frequently develop contrast-induced nephropathy (CIN). This study aimed to assess whether individuals with significant renal impairment assessed by the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula, but not by CG, more often develop CIN following PCI than those without renal impairment by either formula. METHODS: In this cross-sectional study analyzing patients with baseline CG GFR ≥60 ml/min/1.73 m2 before PCI, subjects were divided into two groups according to CIN occurrence. Baseline CKD-EPI GFR was calculated for all patients. RESULTS: We analyzed 140 patients. Baseline GFR was 87.5±21.3 and 77.1±15.0 ml/min/1.73 m2 for CG and CKD-EPI, respectively. CIN occurred in 84.6% of individuals with baseline CKD-EPI GFR <60 ml/min/1.73 m2 vs. 51.1% of those without. Males and those with higher body mass index were more likely to present baseline CKD-EPI GFR <60 ml/min/1.73 m2 (p=0.021). Non-ionic contrast agent use and baseline CKD-EPI GFR ≥60 ml/min/1.73 m2 were protective factors against CIN. Greater amounts of contrast agent and acute coronary syndrome were associated with higher CIN risk. In subjects with serum creatinine <1.0 mg/dl, GFR was more likely to be overestimated by CG, but not by CKD-EPI (sensitivity 100.0%; specificity 52.0%). CONCLUSION: In patients undergoing PCI without renal dysfunction by CG, a finding of CKD-EPI GFR <60 ml/ min/1.73 m2 was associated with a higher probability of CIN, especially among men and those with higher body mass index.

Fórmula de CKD-EPI versus Cockcroft-Gault na predição de nefropatia induzida por contraste após intervenção coronária percutânea, em pacientes sem disfunção renal significativa

Introdução: Nefropatia induzida por contraste (NIC) após intervenção coronária percutânea (ICP) em pacientes com taxa de filtração glomerular (TFG) ≥ 60 mL/min, estimada pela equação de Cockcroft-Gault (C-G), não é infrequente. O objetivo desse estudo foi avaliar a capacidade da equação CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) em predizer NIC em indivíduos sem disfunção renal significativa basal pela fórmula C-G. Métodos: Incluídos pacientes submetidos a ICP entre 2008-2013, com TFG basal ≥ 60 mL/min pela equação de C-G. Estes indivíduos foram divididos em dois grupos, conforme ocorrência ou não de NIC. Para todos os casos, foi calculada a TFG basal conforme a equação do CKD-EPI. Resultados: A amostra consistiu de 140 pacientes. A TFG C-G basal foi de 87,5 ± 21,3 mL/mine de 77,1 ± 15,0 mL/min/1,73 m2para CKD-EPI. NIC ocorreu em 84,6% dos pacientes com TFG CKD-EPI basal < 60 mL/min/1,73 m2, contra 51,1% daqueles com TFG CKD-EPI basal ≥ 60 mL/min/1,73 m2(p = 0,021). Indivíduos masculinos ou com peso corporal elevado apresentaram mais frequentemente TFG CKD-EPI basal < 60 mL/min/1,73 m2. Contraste não--iônico e TFG CKD-EPI basal ≥ 60 mL/min/1,73 m2foram fatores protetores à ocorrência de NIC. Em indivíduos com creatinina < 1,0 mg/dL, o achado de TFG superestimada por C-G, mas não pelo CKD-EPI, foi mais frequente (sensibilidade de 100,0%; especificidade de 52,0%). Conclusões: Em pacientes sem disfunção renal por C-G, submetidos a ICP, o achado de TFG CKD--EPI < 60 ml/min/1,73 m2implicou em maior chance de NIC, principalmente entre indivíduos do sexo masculino e de maior massa corpórea.

How many pygmy marmoset (Cebuella Gray, 1870) species are there? A taxonomic re-appraisal based on new molecular evidence.

The pygmy marmoset, Cebuella pygmaea, the smallest of the New World monkeys, has one of the largest geographical distributions of the Amazonian primates. Two forms have been recognized: Cebuella pygmaea pygmaea (Spix, 1823), and C. p. niveiventris Lönnberg, 1940. In this study, we investigated if the separation of pygmy marmosets into these two clades can be corroborated by molecular data. We also examine and compare coloration of the pelage in light of the new molecular results. We analyzed the mtDNA cytochrome b gene and, for the first time for any Neotropical primate, we used a reduced representation genome sequencing approach (ddRADseq) to obtain data for recently collected, geographically representative samples from the Rio Japurá, a northern tributary of the Rio Solimões and from the Javarí, Jutaí, Juruá, Madeira and Purus river basins, all tributaries south of the Solimões. We estimated phylogenies and diversification times under both maximum likelihood and Bayesian inference criteria. Our analysis showed two highly supported clades, with intraclade divergences much smaller than interclade divergences, indicating two species of Cebuella: one from the Rio Japurá and one to the south of Solimões. The interpretation of our results in light of the current taxonomy is not trivial however. Lönnberg stated that the type of Spix's pygmy marmoset (type locality 'near Tabatinga') was obtained from the south of the Solimões, and his description of the distinct niveiventris from Lago Ipixuna, south of the Solimões and several hundred kilometres east of Tabatinga, was based on a comparison with specimens that he determined as typical pygmaea that were from the upper Rio Juruá (south of the Solimões). As such it remains uncertain whether the name pygmaea should be applicable to the pygmy marmosets north of the Rio Solimões (Tabatinga type locality) or south (near Tabatinga but across the Solimões). Finally, our analysis of pelage coloration revealed three phenotypic forms: (1) south of the Rio Solimoes, (2) Eirunepé-Acre, upper Juruá basin; and (3) Japurá. More samples from both sides of Solimões in the region of Tabatinga will be necessary to ascertain the exact type locality for Spix's pygmaea and to resolve the current uncertainties surrounding pygmy marmoset taxonomy.

Exploring magnetic and imprinted cross-linked enzyme aggregates of rhamnopyranosidase in microbioreactors.

The goal of this work was the development of magnetic cross link enzyme aggregates (mCLEAs) of rhamnopyranosidase (Rhmnase), prepared by chemical cross-linking with functionalized magnetite nanoparticles for glycompounds biosynthesis in microbioreactors (specially design 24-well microplate and mini-packed bed). Rhamnopyranosidase (EC number 3.2.1.40) present high potential in glycocompounds production, with applications in food and pharmaceutical industries. The influence of precipitants, cross-linkers, temperature and time on (m)CLEAs@Rhmnase development were optimized. Biocatalyst activity was accessed in the hydrolysis of 4',5,7-trihydroxyflavanone-7-rhamnoglucoside and kinetic constants in the deglycosylation reaction were evaluated. Rhmnase operational stability was enhanced in mCLEAs, retaining almost 90% initial activity after 7 cycles of 24 h each. In a mini-packed bed bioreactor a maximum volumetric productivity of 140 µmol/L.h was attained. In this bioreactor the operational stability of mCLEAs@Rhmnase were evaluated at a flow rate of 5 mL/h during 5 days and a residual activity of 95% was observed.

A racionalização do espaço como dispositivo da educação superior / Rationalization of space as a device for higher education / La racionalización del espacio como dispositivo de la educación superior

Resumo: Este artigo destaca a racionalização do espaço como elemento significativo da Educação Superior a partir do currículo de um curso de Licenciatura em Educação Física de uma instituição privada de ensino. Por transmitir significados, determinar e separar os locais nos quais os indivíduos circulam e convivem, nele se produzem discursos e práticas culturais que introduzem novas formas de regulação dos sujeitos, constituindo estratégias de subjetivação. Os dados produzidos por meio de observações sistemáticas foram analisados mediante a noção de governamentalidade, entendida por Michel Foucault como a arte de governo de si e dos outros. Os resultados indicam que são realizados investimentos estratégicos em práticas culturais específicas com a finalidade de regular e validar formas de viver afeitas a algumas características do neoliberalismo globalizado como consumismo, espetáculo e volatilidade. (AU)

Abstract: This article discusses rationalization of space as a meaningful element for higher education on the Physical Education curriculum of a private school. Since it conveys meaning and determines and separates the places where people live and circulate, discourses and cultural practices are produced in it that introduce new forms for regulating subjects, which constitute subjectivation strategies. Data produced by systematic observations were analyzed under the notion of governmentality, understood by Michel Foucault as the art of governing self and others. The results indicate that strategic investments are made in specific cultural practices in order to regulate and validate forms of living that are close to some features of globalized neoliberalism such as consumerism, spectacle and volatility.

Improved thermostable polyvinyl alcohol electrospun nanofibers with entangled naringinase used in a novel mini-packed bed reactor.

Polyvinyl alcohol (PVA) electrospun nanofibers were produced using an electrospinning technique. Key parameters (e.g. collectors, distance from needle tip to collector, among others) that influence the structure and morphology of fibers were optimized. The naringinase entrapped in PVA nanofibers retained over 100% of its initial activity after 212h of operation, at 25°C. Chemical crosslinking with several boronic acids further increased the hydrolysis temperature (up to 85°C) and yielded nanofibers with thermal stability up to 121°C. A mini packed bed reactor (PBR) developed to establish the feasibility for continuous enzymatic operation, ran for 16days at 45°C. Highest naringenin biosynthesis was attained at a flow rate of 10mLh(-1). Highest volumetric (78molL(-1)h(-1)) and specific (26molh(-1)genzyme(-1)) productivities were attained at 30mLh(-1). The activity of NGase in electrospun nanofibers remained constant for almost 16days of operation at 10mLh(-1).

Interference of melanin in the susceptibility profile of Sporothrix species to amphotericin B / Interferencia de la melanina en la sensibilidad de especies del género Sporothrix a la anfotericina B

Background. The presence of melanin in the fungal cell is a major virulence factor of the genus Sporothrix since it protects the fungal cells against the defense systems. Aims. The present study aimed to investigate the interference of melanin in the susceptibility of Sporothrix brasiliensis and Sporothrix schenckii sensu stricto to amphotericin B and itraconazole, drugs recommended as therapy for disseminated and subcutaneous sporotrichosis, respectively. Methods. Yeast cells were cultivated in minimal medium with or without l-DOPA in order to induce the production of melanin. Microdilution and killing assay methods were used to determine the antifungal activity against yeast cells with different mounts of melanin. Results. The killing assay showed that melanization protected isolates within the S. schenckii complex from amphotericin B, particularly in the lower concentrations tested. Conclusions. Studies combining amphotericin B and inhibitors of melanin are required in order to avoid this effect (AU)

Antecedentes. La presencia de melanina en la célula fúngica es un importante factor de virulencia del género Sporothrix en el proceso de infección, pues protege al hongo de la acción del sistema inmunitario. Objetivos. El objetivo del presente estudio fue investigar la interferencia de la melanina en la sensibilidad de Sporothrix brasiliensis y Sporothrix schenckii sensu stricto a la anfotericina B y el itraconazol, antifúngicos recomendados como terapia para la esporotricosis diseminada y la subcutánea, respectivamente. Métodos. Se cultivaron células en la fase levaduriforme en medio mínimo con o sin l-DOPA con el fin de inducir la producción de melanina. La valoración de la actividad antifúngica sobre células de Sporothrix con diferente contenido en melanina se realizó mediante microdilución en caldo y curvas de mortalidad. Resultados. El ensayo mostró que la melanización protege de la acción de la anfotericina B a las especies del complejo S. schenckii, particularmente en las concentraciones más bajas ensayadas. Conclusiones. Se requieren estudios de combinación entre diferentes clases de antifúngicos o de anfotericina B con inhibidores de la melanina, con el fin de disminuir o evitar este efecto (AU)

Angioplastia primária de artéria circunflexa anômala após cirurgia de troca valvar mitral / Primary percutaneous coronary intervention of anomalous circumflex artery after mitral valve replacement

A origem anômala da artéria coronária circunflexa do seio de Valsalva direito é a anomalia coronariana mais frequente. Relata-se o caso de uma paciente com artéria circunflexa anômala originada da artéria coronária direita, submetida a cirurgia de troca valvar mitral, evoluindo com choque cardiogênico e oclusão aguda da artéria circunflexa. Foi necessária intervenção coronariana percutânea de emergência e implante de stent não farmacológico. A paciente evoluiu com melhora clínica, sem novas complicações cardíacas...

Anomalous origin of the circumflex coronary artery from the right sinus of Valsalva is the most frequent coronary anomaly. We report the case of a patient with anomalous circumflex artery originating from the right coronary artery, who underwent mitral valve replacement surgery evolving with cardiogenic shock and acute occlusion of the circumflex artery. Emergency percutaneous coronary intervention and bare-metal stent implantation were required. The patient improved clinically without any further cardiaccomplications...

Artéria Coronária Direita Originada da Artéria Descendente Anterior: Uma Rara Anomalia Coronariana / Anomalous Origin of the Right Coronary Artery from the Mid-Left Anterior Descending Artery: A Rare Coronary Anomaly

A artéria coronária única é anomalia rara, que pode estar associada à isquemia miocárdica e morte súbita. Apresentamos o caso de uma mulher jovem, com quadro de angina atípica, cujo cateterismo revelou artéria coronária direita que se originava do terço médio da artéria descendente anterior, uma variante da artéria coronária única.

A single coronary artery is a rare anomaly that may be associated with myocardial ischemia and sudden death. We present a case of a young woman with atypical angina whose coronary angiography revealed a right coronary artery originating from the mid left anterior descending artery, a variant of the single coronary artery.
