This research aims to study dimensions of urban life in the contemporaneous city. It is an effort to understand the functioning of the contemporary city as an artifact that somehow affects social relations. The study focuses on the limits and possibilities of urbanity in the city today, understanding urbanity as a set of factors that favor wealth, diversity and spontaneity of public life. The research aims to show that cities today tend to criate fragmented urban life into at least one of the three urbanity dimensions: spatial dimension, social and temporal dimension. The study involves the analysis of two public spaces in Fortaleza (Praça do Ferreira and the open urban public spaces of the Centro Cultural Dragão do Mar), using Space Syntax Analysis methods and for Post Occupancy Evaluation procedures. Research shows that temporal dimension of urbanity is limited in the public spaces studied. In Praça do Ferreira, spatial and social dimensions are present, but their effects are limited by the temporal dimension. The Dragão do Mar, on the other hand, the spatial and social dimensions of urban life are more limited and more concentrated in time

Brazilian Law n° 9.615 of 24 March, 1998 established new paradigms in the employment relations existent between the soccer athlete and the sport association, both of whom are accustomed to the former legislation. They do not seem to have organized themselves in the sense of understanding the practical effects of the legal precepts currently in force, raising doubts that hinder the professional practice of the former and the performance of the latter in relation to managing these human resources. The purpose of this study is to analyze the degree of knowledge displayed by the professional soccer athlete about the legal recourses at his disposal in relation to the employment relations established in his work contract, as well as investigating the stress habits and stress situations that he most often experiences. This descriptive study consisted of a sample of 105 players under contract with clubs participating in the final phase of the state soccer championship. A questionnaire was used as the data collection instrument, whose analysis allows us to verify the lack of knowledge, on the part of the subjects studied, about the laws that regulate their profession, as well as identifying the stress habits and stress situations that are most reflected in their lifestyle. The lack of knowedge of regulate norms of their profession influences, in a negative way, in the lifestyle of soccer professional athlete from Rio Grande do Norte, Brasil

There is no data about cardiac measurements em Brazilians obtained by CMR. This a muldisciplinary study with the objective of obtaining measurements of the left ventricle (LV) and right ventricle (RV) diastolic diameter (Dd), systolic diameter (Ds), diastolic volume (Dv), systolic volume (Sv), ejection fraction (EF) and myocardial mass in Brazilians. One hundred and seven (54 men and 53 women, mean age of 43.4 ± 13.1 years) asymptomatic individuals without heart disease were submitted to cardiac magnetic resonance (cMR) studies using steady state free precession technique. The means and standard deviations of the parameters of the LV and RV were respectively: LVDD = 4,8 ± 0,5 cm; LVSD = 3,0±0,6 cm; LVDV = 128,4±29,6 ml; LVSV = 45,2±16,6 ml; LVEF = 65,5±6,3%; LV mass = 95,2±30,8.1 g; RVDD = 3,9±1,3 cm; RVSD = 2,5±0,5 cm; RVDV = 126,5±30,7 ml; RVSV = 53.6±18,4 ml; RVEF = 58.3±8,0.0% and RV mass = 26,1±6,1 g. The masses and volumes were significantly higher in men, except for the LVSV. The RV EF was significantly higher in women. There was inverse correlation between RV systolic volume and with age, being more significant in men. This study describes for the first time benchmarks for cardiac measurements obtained by CMR among asymptomatic Brazilians individuals without heart disease and demonstrated differences according to sex and age

Entitled Joana s several mask: the melancholy in Perto do coração selvagem, the work is divided in six parts: the first one consists of the elaboration of a theoretical sketch about the melancholy that it offers the presuppositions that orientate the work, it is a short introduction about the study of the melancholy, a report until our time, the against-depressive ones and the arrival of the melancholy in Brazil and their particularities; the second part raises the theme of the melancholy, deepening its conception until what is called creative melancholy spread by Walter Benjamin, it serves as anchor for Clarice s writing and as a potential force for the processes lived by the characters of this writer; the third part examines Clarice Lispector s method emphasizing important points of production related to the theme of the melancholy, her style is the psychological analysis; the last one parts (fourth, fifth and sixth parts) are divided in topics that illustrate the conflicts, in most of the time contradictory, of the protagonist Joana, as well as, her difficult interaction with the things and the people that surround her. The fragmentary writing, the being's essential searches, the proximity with the death, the multiplicity of voices of feminine, De profundis, surrealist images, the incessant search for the thing , trips, epiphany, the flaw in the language, the taste of the badly, everything starting from melancholy - transformation and creation tool. The work about melancholy (Freud, Benjamin, Kristeva), it s place of ambiguous and contradictory movements. It is a trip that leads to several corporal and psychological sensations of Joana, enigma-scenes to be deciphered and conflicting images that make you wake up for a critical vision of the modern society. Since the beginning, something pulses without stopping, an incessant memory and the search for something that is lost. We are before recyclings of the interior/exterior, pain/pleasure, visions, abyss, ecstasy in the future and an exit through the melancholic light

Entre los años 30 y 40 del siglo pasado, México vio surgir de las cenizas de la revolución mexicana, una figura singular. Frida Kahlo es descrita hasta la fecha de hoy, por el imaginario social – en sus pinturas, en sus fotografías – como una mujer que ha marcado una época y se ha convertido en un símbolo de luchas, y esto se extiende hasta la contemporaneidad. Se ha creado en torno a la pintora mexicana, varias imágenes sociales que se describen en el juego dialógico entre sus obras y sus interlocutores. Teniendo por referencia estas afirmaciones, la investigación aquí presentada ha tomado como procedimiento realizar un análisis de seis cartas escritas por Frida a sus interlocutores amados/amantes – tres hombres con los que estuvo involucrada, emocionalmente, durante diferentes períodos de su vida – y, como objetivo, hacer un mapeo de los ethé construidos por ella en enunciados en los cuales ella "pinta" verbalmente una imagen de sí misma que se revela en las opciones léxicas elegidas para hablar de amor, de traición, de amistad, de dolor y de su estar en el mundo. Por lo tanto, hemos refinado una imagen estética e ideológica de Frida Kahlo que se cubre de pasionalidades distintas y de diversos grados dialógicos. Hay, en el recorte temporal y axiológico que hicimos para esta investigación, una mujer de naturaleza amante y que transformó ese amor en el tono de sus enfrentamientos con los interlocutores con quienes estuvo involucrada emocionalmente. Nuestro análisis está anclado en los postulados teóricos del Análisis Dialógico del Discurso (ADD), cuyo teórico base es el filósofo ruso Mikhail Bakhtin (2003, 2009, 2013) – sobre todo cuando se trata de estilo – y en la teoría de la enunciación de Maingueneau (2008, 2005) y Charaudeau (2006) – en lo que se refiere al ethos discursivo. Esta investigación se inserta en el área de Lingüística Aplicada y tiene un enfoque cualitativo-interpretativo.

A dor óssea decorrente das metástases é um sintoma comum nos tumores avançados de mama e próstata. Nenhuma opção terapêutica isolada é completamente eficaz, e uma série de modalidades costuma ser empregada, entre eles a terapia com radiofármacos, como o samário153-etilenodiaminatetrametileno fosfonato (EDTMP-153Sm). O docetaxel, um taxano com ação sobre tumores avançados de mama e próstata, tem-se apresentado como uma nova opção de tratamento quimioterápico. Muitos pacientes fazem uso simultâneo de EDTMP-153Sm e docetaxel. Este estudo procurou avaliar a influência do docetaxel na biodisponibilidade de EDTMP-153Sm em ratos Wistar, aleatoriamente alocados em 2 grupos de 6 animais cada. O grupo DS (docetaxel/samário) recebeu docetaxel (15 mg/kg) intraperitoneal em dois ciclos com 11 dias de intervalo. Os ratos do grupo S (samário/controle) não foram tratados com docetaxel. Nove dias após a quimioterapia, todos os animais receberam 0.1ml de EDTMP-153Sm via plexo orbital (25μCi). Após 2 horas, os animais foram mortos, e realizaram-se análises de amostras de cérebro, tireóide, pulmão, coração, estômago, cólon, fígado, rim e fêmures. O percentual de radioatividade por grama (%ATI/g) de tecido de cada biópsia foi determinado em contador gama automático (Wizard-1470, Perkin-Elmer, Finland). No 9º dia após 2º ciclo de docetaxel, os ratos tiveram perda de peso significante, passando de 353.66± 22.8g (controle/pré-tratamento) para 314,50±22,09g (p<0.5). Os %ATI/g nos órgãos dos ratos tratados com EDTMP- 153Sm e docetaxel tiveram redução significante nos fêmures direito e esquerdo, rim, fígado e pulmão, quando comparados aos animais não tratados com docetaxel. Em conclusão, a combinação de docetaxel com EDTMP-153Sm foi associada à menor concentração do radiofármaco em órgãos alvo. Futuras investigações sobre o impacto do docetaxel na biodisponibilidade do EDTMP- 153Sm poderão complementar estes achados. Deve-se ressaltar o caráter multidisciplinar deste estudo, que contou com a participação ativa e com a troca constante de conhecimentos entre profissionais das áreas de Medicina Nuclear, Cirurgia, Oncologia, Biologia e Estatística

O desvio gástrico em Y de Roux é a técnica cirúrgica mais utilizada no tratamento da obesidade mórbida. Esta operação reduz o volume do estômago e o comprimento do intestino delgado, gerando alterações estruturais e metabólicas que podem influenciar no resultado de exames cintilográficos de pacientes operados. Com o objetivo de avaliar a biodistribuição pós-operatória do pertecnetato de sódio (Na99mTc) em órgãos de ratos Wistar submetidos à técnica do bypass (desvio) gástrico em Y de Roux (BGYR), foram utilizados 12 ratos distribuídos aleatoriamente em grupo tratado (n=6), submetido à cirurgia do BGYR e o grupo controle (C; n=6). No 15º dia de pós-operatório foi administrado 0,1 mL via plexo orbital de Na99mTc aos animais dos dois grupos, com atividade radioativa média de 0,66MBq. Após 30 minutos, os ratos foram mortos e retirados fragmentos de tireóide, coração, pulmão, fígado, estômago, rim e fêmur. As amostras foram lavadas com solução salina 0,9%, pesadas e submetidas ao Contador Gama 1470, WizardTM Perkin-Elmer-Finlândia para determinação do percentual de atividade radioativa total por grama (%ATI/g) de cada órgão. Empregou-se o teste t de Student para análise estatística, considerando-se significantes as diferenças das médias quando p<0,05. Redução significante na média de %ATI/g foi observada no fígado, estômago e fêmur dos animais submetidos à cirurgia de BGYR comparada ao grupo controle (p<0,05). Nos demais órgãos não houve diferença estatisticamente significativa entre os grupos. Em conclusão, a cirurgia BGYR em ratos modificou a biodistribuição do Na99mTc em alguns órgãos, podendo ter implicações clínicas na interpretação de exames cintilográficos. Este estudo xi teve um caráter multidisciplinar com a participação de pesquisadores das áreas de Cirurgia Experimental, Farmácia, Radiobiologia, Medicina Nuclear e Estatística

A presente pesquisa descritiva do tipo documental centrou-se em analisar as sanções disciplinares aplicadas em caso de doping, a atletas profissionais e não profissionais que atuam no Brasil. A amostragem foi levantada através de um processo de seleção não probabilística intencional, utilizando-se como sujeitos, 18 atletas de uma modalidade esportiva dita não profissional: atletismo e 19 de uma modalidade profissional: futebol, de ambos os sexos, os quais tenham sido flagrados pelo exame de controle de dopagem da Confederação Brasileira de Atletismo (CBAt) e da Confederação Brasileira de Futebol (CBF). Como instrumentos de análise, foram utilizados os diagnósticos de dopagem positiva, arquivados junto a CBAt e CBF; além dos processos julgados pelo Superior Tribunal de Justiça Desportiva (STJD) do atletismo entre os anos de 2003/2007 e os processos julgados pelo STJD do futebol no ano de 2007. Os resultados demonstram que as sanções aplicadas aos desportistas diferem muito entre as modalidades incluídas no estudo. Enquanto encontramos, no atletismo a aplicação de sanções em conformidade com o Código Mundial Anti Doping (CMAD) com penalidades de no mínimo de dois anos, no futebol encontrou-se grande número de absolvições ou aplicação de penalidades conforme o Código Brasileiro de Justiça Desportiva (CBJD) que prevê penalidades muito inferiores. Por outro lado verificou-se ser a modalidade Futebol a que mais realiza controles, sendo certo que durante o ano de 2007 o desporto profissional realizou 4832 testes, ao passo que o desporto dito não profissional realizou tão somente 281. O caráter multidisciplinar do trabalho 12 pôde ser caracterizado pelo emprego de técnicas que envolveram direito, educação física, farmacologia

Heart transplantation (HT) represents one of the greatest advances in medicine over the last decades. It is indicated for patients with severe heart disease unresponsive to clinical treatment and conventional surgery, poor short-term prognosis and a 1- year mortality rate over 40%. HT has improved survival worldwide (80% in the first year, 70% in five years and 60% in ten years). However, the procedure has been associated with weight change and increased risk of secondary conditions such as diabetes, hypertension, dyslipidemia and obesity due to immunosuppressive therapy following transplantation. The objective of this study was to determine the impact of weight change on the metabolic stability of HT patients. The study was retrospective with data collected from the records of 82 adult patients (83% male; average age 45.06±12.04 years) submitted to HT between October 1997 and December 2005 at a transplantation service in Ceará (Brazil). The selected outcome variables (biopathological profile, weight and body mass index―BMI) were related to biochemical and metabolic change. The results were expressed in terms of frequency, measures of central tendency, Student s t test and Pearson s correlation coefficients. The analysis showed that following HT the average global BMI increased from 23.77±3.68kg/m2 to 25.48±3.92kg/m2 in the first year and to 28.38±4.97kg/m2 in the fifth. Overweight/obese patients (BMI ≥ 25 kg/m2) had higher average levels of glucose, total cholesterol, low-density lipoprotein and triglycerides than patients with eutrophy/malnutrition (BMI < 25 kg/m2). In conclusion, overweight/obese patients were likely to present higher average levels of glucose, triglycerides, total cholesterol and fractions than patients with eutrophy/malnutrition, indicating a direct and significant relation between nutritional status and weight change in the metabolic profile of HT patients

A esplenectomia é indicada em doenças hematológicas, hiperesplenismo grave, traumas e tem sido causa de importantes alterações metabólicas e imunológicas. O objetivo do presente trabalho é avaliar se a retirada do baço altera a biodistribuição do radiofármaco DMSA Tc99m em ratos Wistar e se há correlação com possíveis alterações da função renal. Foram usados dois grupos: esplenectomia (n=6) e controle (n=6) animais não operados. Após 15 dias, foi administrado 0,1 ml de DMSA-Tc99m via plexo orbital (0,66 MBq). Trinta minutos depois, foram retiradas amostras do rim, coração, pulmão, tireóide, estômago, bexiga, fêmur, sangue. Após pesadas as amostras, foi determinado o percentual de radioatividade/g (% ATI/g) em cada uma delas, com o Wizard Gama Counter Perkin-Elmer . Dosadas uréia e creatinina sérica, hematócrito, plaquetas e leucócitos. Estatística pelo teste t, com significância 0,05. Foi observada redução significante no %ATI/g no rim e sangue (p<0,05) dos animais esplenectomizados, aumento significante (p<0,05) da uréia (88,8±18,6mg/dL) e creatinina (0,56±0,08), comparado aos controles (51,5±1,6 e 0,37±0,02mg/dL, respectivamente) assim como leucocitose, aumento de plaquetas e redução de hematócrito. Em conclusão, a esplenectomia provocou comprometimento da função renal, repercutindo na alteração da captação de DMSA 99mTc pelo rim de ratos. Uma parceria entre a Unidade de Medicina Nuclear da Liga Norteriograndense Contra o Câncer e o Núcleo de Cirurgia Experimental da Universidade Federal do Rio Grande doNorte tornou possível a realização deste trabalho, que contou com a participação de profissionais de diferentes áreas como: Biologia, Biomedicina, Medicina Nuclear, Cirurgia Geral, Bioquímica e Estatística, atestando dessa forma o caráter multidisciplinar do trabalho

O desenvolvimento do esporte paraolímpico nacional e internacional tem estimulado maior participação das pessoas com deficiência em praticar atividades desportivas, exigindo dos atletas incrementos na intensidade e freqüência nos treinamentos e competições, o que impulsiona, ainda mais, os índices de lesões esportivas traumato-ortopédicas. Objetivamos neste estudo descritivo analisar as lesões traumato-ortopédicas mais frequentes nos atletas paraolímpicos, sua localização nos segmentos corporais, correlacionando-as com as modalidades esportivas praticadas pelos integrantes das Seleções Brasileiras Paraolímpicas. O presente estudo foi realizado com 82 atletas paraolímpicos da Seleção Brasileira de Atletismo, Halterofilismo, Natação e Tênis de mesa, de ambos os sexos, com deficiências motoras, visual e intelectual, participantes dos Campeonatos Mundiais, no ano de 2002, sendo os mesmos selecionados de forma não probabilística intencional os quais atenderam os critérios de inclusão e exclusão estabelecidos para o estudo. Para a avaliação clínica das lesões traumato-ortopédicas foram utilizados como instrumentos de medida o Prontuário do Departamento Médico do Comitê Paraolímpico Brasileiro (técnica da observação através da história clinica esportiva do atleta / anamnese e exame físico), entrevistas com os atletas e exames complementares das lesões traumato-ortopédicas quando necessárias. Os resultados do estudo com os atletas paraolímpicos revelaram prevalência de lesões no atletismo (MMII = 64,9%, coluna = 19,3% e MMSS = 15,8%); halterofilismo (coluna = 54,5%, MMSS = 36,4% e MMII = 9,1%); natação (MMSS = 44,4%, coluna = 38,9 e MMII = 16,7%) e tênis de mesa (MMSS = 56%, coluna36% e MMII = 8%), com predomínios das lesões músculotendineas em todos os esportes pesquisados. Os resultados apresentados nos permitem concluir que em todos os esportes pesquisados os atletas paraolímpicos apresentaram um predomínio das lesões músculo-tendíneas, tendo como localização no atletismo, lesões nos membros inferiores, no halterofilismo na coluna vertebral e membros superiores, na natação e no tênis de mesa, nos membros superiores e coluna vertebral

The biliopancretic diversion with duodenal switch is one of the mixing techniques used in the treatment of morbid obesity. The duodenal switch reduces the stomach capacity and leaves only 50-100 cm of small intestine for nutrition and absorption. The surgery produces hormonal, structural and biochemical changes, which can influence on the result of scintigraphic examinations in operated patients. With the objective of evaluate the postoperative biodistribution of sodium pertechnetate (Na99mTcO4) in brain, thyroid, heart, lung, liver, spleen, kidney, stomach, duodenum, pancreas, small intestine, bladder, muscle and bone of Wistar rats. The rats were randomly allocated into 3 groups of 7 rats each: the duodenal switch group (DS), the control group (C) and the sham group (S). They were operated under anesthesia and aseptic technique. In the tenth postoperative day, 0.1mL of sodium pertechnetate was injected via orbital plexus. After 30 min the animals were killed with overdose of anesthetic and samples of liver, spleen, pancreas, stomach, duodenum, small intestine, thyroid, lung, heart, kidney, bladder, muscle, bone and brain were harvested, washed with saline and weighed. The detention of radioactivity was made using the automatic Gamma Counter Wizard, PerkinElmer and the percentage of activity per gram of tissue (%ATI/g) was calculated. There was no early or late mortality in either rats groups. The values of percent radioactivity per gram of tissue (%ATI/g), showed no significant difference in liver, stomach, small bowel, duodenum, kidney, heart, bladder, bone and brain, when compared the DS rats with sham and controls rats. A postoperative significant increase in mean %ATI/g levels was observed in spleen, pancreas and muscle in group DS rats, as compared to group S and C rats (p<0.05). In the lung there was an increase and in thyroid a decrease in mean %ATI/g of DS rats, when compared to sham rats (p>0.05). In conclusion, the biliopancreatic diversion with duodenal switch in rats modified the biodistribution of sodium pertechnetate in thyroid, lung, pancreas, spleen and muscle. The study had the participation of the departments and laboratories researches, as Nucleus of Experimental Surgery, Department of Surgery, Laboratory of Radiobiology, Department of Pathology and Service of Nuclear Medicine, certifying the character of a multidisciplinary research

Massive resection of the small intestine results in short bowel syndrome with anti-absorptive effect and repercussions on the metabolism. Morphologic and functional evaluation may be necessary in order to control wrapped organs. Scintigraphy an examination with little invading and no biologic damage can be used. The purpose were to assess the biodistribution of sodium pertecnetate in organs of rats subjected to massive resection of the small intestine, the intestinal adaptation of the remnant intestinal mucosa and weight curve evaluation in the postoperative period. Twenty-one Wistar rats were randomly allocated into three groups (n = 7). The operated group named short bowel (SB) after anesthetized was subjected to massive resection of the small intestine; the control group (C), and sham group (SHAM). On the 30th postoperative day, 0.l mL of sodium pertechnetate was injected into the venous orbital plexus. After 30 minutes, the rats were killed with an overdose of anesthetic, and fragments of the liver, spleen, pancreas, stomach, duodenum, small intestine, thyroid, lung, heart, kidney, bladder, muscle, femur and brain were harvested. The percentage of radioactivity per gram of tissue (%ATI/g) was determined using Gama Counter WizardTM 1470, PerkinElmer to all samples. Biopsies of 3 cm remaining jejunum were removed to histological analyses. Analysis of variance (ANOVA) and the Tukey test for multiple comparisons were used, considering p<0.05 as significant. The study had the participation of some departments and laboratories, as Nucleus of Experimental Surgery, Department of Surgery, Laboratory of Radiobiology, Department of Pathology and Service of Nuclear Medicine, certifying the character of a multidisciplinary research. The results were no significant differences in %ATI/g of the sodium pertechnetate in the organs of the groups studied (p>0.05). An increase in the weight of the SB rats was observed after the second postoperative week. The jejunal mucosal thickness of the SB rats was significantly greater than that of C and sham rats (p<0.05. The biodistribution of sodium pertechnetate was not affected by massive intestinal resection in rats. An adaptive response by the intestinal mucosa probably contributed to the reversion of weight loss and the biodistribution of sodium pertechnetate was not affected by the surgery

The purpose of the present study is to identify the dermatoglyphic and somatotypic characteristics and the physical qualities of athletes from the under-17 State volleyball team, in Rio Grande do Norte, Brazil. The sample was composed of athletes, n = 14, aged 15.0 ± 0.88 years, weight (Kg) 58.3 ± 5.90 and height (cm) 169.4 ± 7.97, members of the referred team. For data collection Cummins & Midlo s (1942), o dermatoglyphic method and Heath & Carter s (1967) somatotypic method were used and to evaluate physical qualities, 2400m, 50m, Shuttle Run, abdominal , Sargent test and medicine-ball toss were performed. Fingerprints show that the group presents genetic predisposition for the following physical qualities: explosive force and velocity. As to somatotype, the group was endo-ectomorphic. At physical evaluation the group presented low Vo2 max values and reasonable levels of explosive force, local muscular endurance, agility and velocity. We conclude that: according to the dermatoglyphic model observed, the group needs training strategies to improve coordination and agility; somatotype reveals the necessity for reducing fat levels and increasing muscular mass; the evaluation of physical qualities demonstrates the need for better physical preparation. This study traces the profile of the under-17 volleyball player from Rio Grande do Norte, with respect to genetic and somatotypic aspects and physical qualities, which will serve as a parameter for future state teams
