This study investigated the influence of partial colectomy associated with hepatectomy on the biodistribution of the 99mTc-phytate, on metabolic parameters, as well as labeling and morphology of red blood cells. Wistar rats were distributed into three groups (each with 6), nominated as colectomy, colectomy+hepatectomy and sham. In the 30th postoperative day all rats were injected with 99mTc-phytate 0.1mL i.v. (radioactivity 0.66 MBq). After 15 minutes, liver sample was harvested and weighed. Percentage radioactivity per gram of tissue (%ATI/g) was determined using an automatic gamma-counter. Serum AST, ALT, alkaline phosphatase and red blood cells labeling were determined. The liver %ATI/g and red blood cells labeling were lower in colectomy and colectomy+hepatectomy rats than in sham rats (p <0.05), and no difference was detected comparing the colectomy and colectomy+hepatectomy groups. Red blood cells morphology did not differ among groups. Serum levels of AST, ALT and alkaline fosfatase were significantly higher in colectomy+hepatectomy than in colectomy rats (p<0.001). Hepatectomy associated with colectomy lowered the uptake of radiopharmaceutical in liver and in red blood cells in rats, coinciding with changes in liver enzymatic activity

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

Neste trabalho procuramos estudar o fenômeno do bruxismo, definido como o ato de apertar e/ou ranger os dentes, hábito prejudicial à região orofacial relacionado a varáveis psicossociais. O bruxismo é frequentemente associado aos aspectos emocionais, entre os mais ressaltados, a ansiedade e o estresse, podendo implicar em alterações das estruturas orofaciais, modificações funcionais e inclusive com repercussões sociais. Deste modo, torna-se relevante evidenciar que a pesquisa foi desenvolvida, visando o contexto multidisciplinar, abrangendo a Fonoaudiologia, Odontologia e Psicologia. Objetivo: verificar associação entre bruxismo, ansiedade e as principais queixas referentes à função mastigatória. Método: participaram oitenta voluntários, divididos entre grupo com bruxismo (N=40) e sem bruxismo (N=40), do sexo masculino e feminino. O diagnóstico do bruxismo foi realizado através do exame clínico. Para avaliar os níveis de ansiedade empregou-se o Inventário de Ansiedade Traço e Estado e para os aspectos psicossociais um questionário com questões estruturadas referentes às atividades diárias, focando a função mastigatória (para o grupo com bruxismo). Resultados:: Os resultados permitem evidenciar diferenças significativas entre os grupos analisados, a média e desvio padrão de ansiedade estado no grupo com bruxismo, 42,7±9,6 e sem bruxismo 38,6±8,2 (p ≤0,04) e de ansiedade traço respectivamente 44,5±11,0 e controle 40,7±9,5 (p ≤0,11). O relato dos participantes com bruxismo evidenciou como principais queixas durante a mastigação, dor na face ao mastigar, cansaço muscular na face, cefaleia ao mastigar e presença de ruídos articulares. Conclusões: Evidenciamos uma associação dos fatores emocionais como a ansiedade e o bruxismo, e como resultante os pacientes apontam que a função mastigatória encontra-se depreciada

condições de saúde são questões que precisam ser investigadas na nossa sociedade. Diante da inexistência de estudos que abordem os aspectos psicológicos e físicos desses profissionais, tornou-se necessário e relevante esta investigação para a área de segurança pública num contexto multidisciplinar. O estudo objetivou verificar as características da aptidão física e psicológica relacionada à saúde de policiais militares do Batalhão de Atividades Policiais Especiais (BOPE), da Polícia Militar do Rio Grande do Norte. A amostra selecionada de forma aleatória foi composta de 64 militares de diferentes graduações, do sexo masculino com idade média de 26,2±2,6 anos. Foram utilizados como instrumentos de medida o Questionário de Saúde Geral de Goldberg para avaliar a saúde geral; uma balança digital da marca Techline®, e estadiômetro portátil da marca Sanny® para avaliar a massa corporal e a estatura; fita antropométrica metálica Sanny® para avaliar a perimetria (circunferência do braço contraído, circunferência da panturrilha); paquímetro Sanny® para avaliar os diâmetros ósseos (bi-epicondilar umeral e bi-epicodilar femural); adipômetro Harpender® para avaliar a espessura das dobras cutâneas; dinamômetro manual Jamar para avaliar a força de preensão manual; flexímetro Sanny®, fotocélulas CEFISE modelo Speed Test Fit e o YoYo Intermitent Recovery Test para avaliar o desempenho físico ( flexibilidade, agilidade, velocidade e endurance anaeróbica). Os participantes apresentaram valores elevados para risco de distúrbio ou mesmo a presença de distúrbio, no que se refere à saúde geral; o grupo estudado é classificado como mesoendomorfico, predominando características de endurance aeróbico e anaeróbico e força que foram relacionadas com os aspectos psicológicos. O perfil somatotípico meso-endomorfo parece interferir nos elevados riscos de distúrbios psicológicos advindos da atividade laboral exigida, apesar dos mesmos apresentarem um bom desempenho físico

Introdução: O dano miocárdico na doença de Chagas resulta tanto da ação parasitária quanto da resposta imune do hospedeiro humano. O mimetismo molecular entre proteínas do Trypanosoma cruzi e vários antígenos do hospedeiro tem sido amplamente descrito gerando células T CD8+ e anticorpos autorreativos. Entretanto, a geração dos autoanticorpos e seu papel na imunopatogenia da doença de Chagas ainda não têm sido elucidados, o que nos levou, neste trabalho, a avaliar a produção de imunoglobulina G total (IgGt) e seus isotipos anti-T. cruzi, proteínas cardíacas e sua possível associação com as diferentes formas clínicas da doença de Chagas. Métodos: A produção de IgGt e isotipos foi mensurada pelo método de ELISA no soro de pacientes com as formas clínicas indeterminada (IND, n=72), cardíaca (CARD, n=47) e digestiva/cardio-digestiva (DIG/CARD-DIG, n=12) da doença de Chagas, usando como antígenos as formas epimastigota e tripomastigota do T. cruzi e proteínas cardíacas humana (miosina e troponina T). As amostras de indivíduos não infectados saudáveis (CONT, n= 30) e pacientes com cardiomiopatia isquêmica (ISCH, n=15) foram usadas como controle. Os títulos de autoanticorpos foram correlacionados com parâmetros da função cardíaca obtidos por exames eletrocardiográficos, radiográficos e ecocardiográficos. Resultados: Neste estudo foram incluídos 131 indivíduos sem diferença significativa relativa à idade ou sexo. Destes, 55% foram classificados como IND, 35,9% CARD e 9,1% DIG/CARD-DIG. Os títulos de IgGt foram mais elevados em pacientes com as formas clínicas IND, CARD e DIG/CARD-DIG do que em indivíduos CONT e ISCH usando os antígenos as formas tripomastigotas e epimastigotas do T. cruzi e, proteínas cardíacas humanas. Os pacientes com formas clínicas CARD e DIG/CARD-DIG mostraram a produção mais elevada de IgG total dirigida contra antígenos de tripomastigota e epimastigota do que os IND. Os grupos de pacientes IND e CARD apresentaram uma similar produção de IgG total específica direcionada à miosina e troponina T, e mais elevada do que em indivíduos CONT e ISCH. Há uma correlação negativa entre a produção de anticorpos anti-proteínas cardíacas com a fração de ejeção do ventrículo esquerdo (FEVE) em pacientes chagásicos crônicos. Os pacientes foram agrupados em baixo e alto produtores de autoanticorpos e comparados com a fração de ejeção demonstrando que em pacientes alto produtores de anti-troponina T (p=0.042) e miosina (p=0.013) a FEVE foi mais baixa do que os baixo produtores. A maioria dos pacientes chagásicos produz simultaneamente autoanticorpos direcionados à ambas proteínas cardíacas (r=0.9508, p=0.0001). Conclusões: Estes resultados indicam que os autoanticorpos anti- troponina T e miosina cardíaca parecem induzir redução FEVE e deve ser associado com o desenvolvimento de cardiomiopatia chagásica

This study had as objective to identify to the perception of mothers and professionals of health on the attention to the health of HIV-Positive children/adolescents in the city of Natal-RN. It is a descriptive-exploratory study with quantitative and qualitative approach, carried through in the Giselda Trigueiro Hospital and in the State and Municipal Health Councils in Natal - RN, from march to december of 2005. The sample was composed by 56 participants, 33 mothers of children who use specialized assistance and 23 professionals. Data collection occurred with the application of a half-structuralized interview. Quantitative data were analyzed through descriptive statistics and qualitative data were submitted to content analysis. Prevailing categories in relation to the cartography of the attention to seropositive children and adolescents in Natal were: Organization and dynamics of the attention; Institutional management and human development; Control and prevention; other contexts of attention; relationship/communication team-patient and organization and functioning of the services. The profile epidemiologist of the children, adolescents and of the people/mothers, who take care of them with HIV/Aids, followed the evolution of the epidemic in the country and the world. It was verified that mothers need care and information; however they make a positive evaluation of the attendance they receive. It was also observed many gaps in the services of assistance, in which the researched group was attended, beyond imperfections in the communication between health professionals and users. The professionals recognize the advances that the politics represent for the assistance of people with Aids; however feel themselves limited by the precariousness of the system and the partner-economic conditions of the people. According to these data, it can be verified great challenges to go through in the context of integrality of the assistance to HIV positive children and adolescents in the city of Natal and in the improvement of the communication in the institution of reference

The present study seeks to understand tooth loss by investigating the social representations in the daily life of elderly individuals, thus characterizing itself as a comparative and analytic research. It is known that tooth loss is a common occurrence in elderly individuals, interfering at the psychosocial and biological levels, through its functional, esthetical and social implications. The area of oral health in Brazil is lacking studies on this topic, especially with respect to the psychosocial aspects of the elderly. The Theory of Social Representations and the Central Nucleus Theory were selected for theoretical-methodological support. The Free Association of Words Test was used, whose inducing stimulus were the words tooth loss , in which each subject was asked to associate 3 words, to respond to a questionnaire related to socio-economic conditions and containing an investigation of tooth loss, access to odontological services and the need for dental treatment, and to undergo a focus group interview. The study sample consisted of 120 individuals 60 years of age or over, resident in Natal, RN, Brazil and participants of the Live Together to Live Better group of the Basic Health Unit of Felipe Camarão Residential District and Unati (Open University of the Elderly); an interview was performed with 36 subjects. Data analysis was performed by Evoc 2000, SPSS/99, Graph Pad and Alceste softwares. The results demonstrate that the central nucleus of the social representations of tooth loss for the Live Together group emerged from the difficulty in eating categories, showing a relation between physiologic necessity, desire and pleasure from eating, not to mention the pain that resulted from justifying the tooth loss. Besides the central discourses, the following peripheral elements were gathered: difficulty in adapting to the prosthesis, treatment and difficulty in speaking. All of these categories, except the last, also comprised the class themes of the group interview. For the Unati group the central nucleus emerged from the socio-economic difficulties categories, demonstrating a narrow relation between poverty, access to health and education and esthetics, confirming in the discourse of common sense, the association between tooth loss and aging. At the margin of the central discourses was collected the peripheral element difficulty in adapting to the prosthesis, found both in the Live Together and Unati groups, which expresses the resistance of the subject to this new situation and the failure of the rehabilitation treatment in the sense of reviving the memory of their natural teeth. All of these categories also constitute the class themes of the of the group interview. Thus, through the study of the social representations, we can reveal a reality in the perspective of the social subjects, contemplating the multiple facets of the social-cultural reality experienced by these individuals

The Back School has been used to prevent and to treat back pain since 1969, however its effectiveness still is controversy in literature. The objective of this study was to evaluate the effectiveness of a program of "Back School" in patients with nonspecific chronic low back pain, directed by rheumatologists and orthopedic doctors to Physiotherapy School Clinic of Universidade Potiguar (UnP) Natal/RN- Brazil, in period of May/2002 to December/2003. Seventy patients, with age varying from 18 to 60 years, were randomized in two groups: Experimental group (group A) with 34 patients, which was subdivided in groups with 6 to 8 components. This group participated of a theoretician and practical program of Back School with 4 lessons, one day per week, with 60 minutes of duration; to the Control group (group B), with 36 patients, was explained that the group should stay four months in a waiting list . Both groups, had been carried through three evaluations, by a blind, to patient group, independent observer: initial evaluation, after four and sixteen weeks. The following variables were analyzed: pain intensity, measured by analog visual scale (AVS), functional disability, measured by disability questionnaire of Roland and Morris and the spinal mobility measured by Schöber s method. In statistical analysis it was used variance analysis ANOVA, the test of Newman-Keuls multiple comparations, and the Pearson correlation coefficient, with significance level p<0.05. Thirteen patients (18,6%) didn t complete the evaluations, (5 from experimental group and 8 from control group). At last, 57 patients were studied, (29 from Experimental group and 28 from Control group), it was observed a significant statistical improve just for Experimental group in variables pain intensity (p=0,0001), functional disability

Investigations in the field of pharmaceutical analysis and quality control of medicines require analytical procedures with good perfomance characteristics. Calibration is one of the most important steps in chemical analysis, presenting direct relation to parameters such as linearity. This work consisted in the development of a new methodology to obtain calibration curves for drug analysis: the stationary cuvette one. It was compared to the currently used methodology, and possible sources of variation between them were evaluated. The results demonstrated that the proposed technique presented similar reproducibility compared to the traditional methodology. In addition to that, some advantages were observed, such as user-friendliness, cost-effectiveness, accuracy, precision and robustness. Therefore, the stationary cuvette methodology may be considered the best choice to obtain calibration curves for drug analyis by spectrophotometry

The discussion we have established in this study is about how the practice is developing educational projects based on work with because the methodological choice of the teacher. The study of an ethnographic qualitative approach was conducted with a group of six teachers in two public schools in School Administrative Zone north of the city of Natal / RN. Data were constructed from semi-structured, reinforced by the direct observation of the practice of teaching of teachers. The goals outlined were to identify the reasons why the option for the project, listing the benchmarks that subsidized their construction, the observation of everyday experience in educational planning and development of projects developed. In the light of information we can notice a complex and even contradictory, which is confusing the concepts and practices are weakened. The analysis revealed inconsistencies between theory and practice in working with projects, the fruit of little theoretical development of teachers. The adoption of the project as a methodological option has meant a change in direction of the effective action didactic. Reflects on this situation, it was concluded that there is a need to broaden the understanding of the significance of this type of work, covering the different dimensions that involve the practice of research, research and training of teachers. Even preventing the intentions and initiatives of the teachers, it must be emphasized is the process of learning within an approach that focuses the process of learning in multiple dimensions, inter-relational, both the capabilities of students in the areas of knowledge.
