Expressão e percepção dos sentimentos de amor e desamor na vivencia da díade amorosa

Esta pesquisa teve como objetivo tornar explícita a vivência do sentimento de amor e desamor da díade amorosa de um grupo de pessoas, através de uma abordagem existencial fenômeno lógica. Caracterizou-se por uma pesquisa exploratória de campo que apreendeu os relatos de histórias já vividas por 69 pessoas, mulheres e homens, universitários dos cursos de Educação Física, Engenharia e Filosofia, tendo a maioria a idade de 22 e 23 anos. Com pressupostos da técnica dos Incidentes Críticos norteando uma entrevista, procurou-se captar como as pessoas expressam e percebem o sentimento de amor e desamor em relação ao companheiro(a) da díade amorosa. O sentimento de amor foi expresso por ações tais como "Declarar", "Acarinhar", "Presentear", "Confiar", "Ceder", "Mostrar interesse" através de "ajudar em momentos difíceis", "Apoiar/Preocupar", Acolher", "Procurar o outro" e "Querer estar junto". O sentimento de desamor foi apreendido como “Agredir", "Terminar o relacionamento", "Ser egoísta", "Mostrar desinteresse", através da "Indiferença, mostrar-se frio e distante", "Desatenção/Indelicadeza", "Ter outros interesses em momentos de lazer que não estar com a pessoa", "Interessar-se amorosamente por outra pessoa" e "Mostrar dúvidas". Pela análise efetuada observa-se que homens e mulheres não possuem diferenças significativas no número dos relatos por categorias. No entanto homens apresentaram maior proporção de relatos de amor em "Acarinhar" e "Presentear" e as mulheres em "Confiar" e "Ceder". Foram levantadas também as definições pessoais de amor e desamor e os indícios autoperceptivos do estar amando, encontrando-se alguma correspondência com as categorias vivenciais. Nenhuma diferença significativa foi encontrada em termos de proporção e conteúdo entre as pessoas pertencentes aos diversos cursos.

Rap e literatura popular: duas culturas, uma expressão

Este trabalho tem como objectivo estudar as manifestações de duas cultura distintas, o Rap e a Literatura Popular, a cultura urbana e a cultura rural, aparentemente antitéticas. Procurar-se-á problematizar e, por conseguinte, entender de que forma estas duas culturas podem ser consideradas como uma expressão popular caracterizada pela composição literária, rítmica e musical, através de elementos do quotidiano. Para além do mais, tanto no Rap como na Literatura Popular, os compositores fazem parte de um grupo marginalizado, e como tal, as suas canções abordam ou denunciam as dificuldades diárias e situações de injustiça social. As várias acepções do conceito de cultura contribuem para uma melhor compreensão da vasta diversidade cultural e do reconhecimento e respeito que se deve ter em relação às culturas ditas minoritárias. Estreitamente associada à cultura está a questão da identidade, que permite que um indivíduo se aproxime ou se distancie de um determinado grupo. Neste sentido, sublinhar-se-á as marcas culturais e identitárias de cada grupo. Será nosso intuito encontrar similitudes e divergências numa análise rigorosa do corpus de trabalho. Com efeito, a análise de composições de Rap e de Literatura Popular portuguesas ajudarão a demonstrar não só a grande capacidade criativa e performativa dos sujeitos, como as componentes lúdica e de defesa de uma igualdade social. Finalmente, procurar-se-á demonstrar que, na nossa sociedade relacional e dinâmica, estas culturas podem estar em diálogo e partilhar experiências de actuação e de divulgação cultural.

O golfe enquanto meio de compreensão e transformação do indivíduo

Cada vez mais, o fenómeno desportivo é suportado pelo conhecimento de um conjunto de disciplinas científicas que, quando devidamente articuladas sob um quadro de complexidade coerente, promovem um melhor entendimento acerca das mudanças que ocorrem no indivíduo. Neste sentido, através da realização do presente trabalho, procurámos perceber qual o enquadramento conferido ao golfe e se esse enquadramento é compatível com a ideia de o golfe servir de ferramenta para a compreensão e transformação do indivíduo. Para isso, através da literatura existente, procurámos conhecer quais as suas origens e evolução, de que forma está caracterizado (conceitos e opiniões dos diferentes agentes desportivos), qual a sua expressão (ao nível dos diferentes mercados) e que tipo de estudos e investigações existentes (focados no jogador) apoiam a sua evolução. De seguida, realizámos o enquadramento do golfe à luz da Taxonomia das Actividades Desportivas de Fernando Almada e analisámos o swing com base no Modelo Taxonómico dos Desportos Individuais. Como forma de testar a conjectura de que o golfe pode servir para a compreensão e transformação do indivíduo, realizámos uma situação experimental com um grupo de 14 jogadores (com handicaps compreendidos entre 5 e 32) de forma a perceber se existiam diferenças significativas no seu desempenho (p _ 0,05), quando expostos a diferentes condições (uma condição confortável e a uma condição de desconfortável). Os resultados globais (da amostra) não evidenciaram diferenças significativas, ao contrário de alguns dos resultados individuais, que por sua vez, permitiram estabelecer ligações com as diferentes variáveis funcionais inerentes à realização do swing,possibilitando-nos a formulação de um conjunto de hipóteses que poderão servir de orientação à compreensão de algumas das características mais marcantes do jogador.

Nas asas de Ícaro: uma análise da Pedagogia Freinet do 2º ao 5º ano do Ensino Fundamental na perspectiva da ação docente continuada

Célestin Freinet was one of the most memorable educators of the twentieth century. He presented some educational alternatives that had the objective of stimulating the construction of pedagogic actions to promote the social development of the student based upon a work centered on the free expression as the way to self-structure the knowledge. With a permanent proposal of research based on the enquiry-based learning, Freinet set human capacity (cognitive, social-affective, psychometrical) taking cooperation in consideration on the processes of knowledge construction. Based on this referential, this present work has the objective to show Freinet s pedagogy in a continuous teaching action from 2nd to 5th grade focusing the teacher s discourse and also the educative practice of the students of a city public school in Natal. The observed work revealed the teacher s discourse and educative experience and delineated the students development while immersed into Freinet s educational practice. By virtue of the nature and specificity of the theme that guided our research, we chose a qualitative approach to it, as a way of conducting ourselves during our investigative process. We observed and analyzed the method that was used to conduct the activities in the classroom, as well as the ways of expression that the children used through drawings, words (oral text), or through writing. We highlight, among the written texts, the individual and collective texts, and also letters and notes, which during some moments served as a base to express a diversity of languages. The results, after a analyzing the research data, point towards a teaching practice that favors the construction of a significant learning process through the grasping of the school environment, on which all these factors are based: society, knowledge acquisition, abilities, attitudes and values. This learning process also strengthens human solidarity bonds and mutual tolerance, on which the student s social life is seated.

Expressão imuno-histoquímica metaloproteinase -1, -2 e -9 em ameloblastoma sólido e tumor odontogênico adematóide

Ameloblastoma and adenomatoid odontogenic tumor are odontogenic tumors arising from the odontogenic epithelium with distinct clinical behavior. In attempt to comprehend the interaction between the odontogenic tumor cells and the extracellular matrix, the present work evaluated and compared the immunohistochemical expression of the matrix metalloproteinases-1 (MMP-1), -2 (MMP-2) and -9 (MMP-9) in 20 cases of ameloblastoma and 10 adenomatoid odontogenic tumor. MMP-1 exhibited exuberant expression in the parenchyma and in the stroma of both studied tumors, while the MMP-2 showed varied expression with about of 80% and 60% of the neoplastic cells exhibiting positivity in the ameloblastoma and adenomatoid odontogenic tumor, respectively. With relation to the MMP-2 expression by the mesenchymal cells, it was observed that 65% of the ameloblastoma and 80% of the adenomatoid odontogenic tumor were positive. The immunoreactivity of MMP-9 was detected in all studied cases, although its expression had occurred predominantely in less than 50% of the parenchyma cells of the ameloblastoma, while in about of 60% of the adenomatoid odontogenic tumor more than 50% of cells were positive. The mesenchymal cells were positive to MMP-9 in 65% of the ameloblastoma and in 80% of the adenomatoid odontogenic tumor, respectively. Statistically significant difference was observed to the MMP-1 expression with relation to MMP-2 and MMP-9 in the ameloblastoma (p < 0.001). It was not possible to perform statistical analysis to the cases of adenomatoid odontogenic tumor, however there was a tendency toward a differential expression of the MMP-1 with relation to other studied MMPs. These results suggest that MMP-1, - 2 and -9 are implicated in the growth and progression of both tumors analyzed as well as the more pronounced participation of the stroma in the ameloblastoma could together to be related to the higher clinical aggressiveness

Expressão imuno-histoquímica dos marcadores angiogênicos CD105 (endoglina) e CD34 em hemangiomas e granulomas piogênicos orais

Angiogenesis, a fundamental mechanism in tumor development, is used for differential diagnosis and prognosis purposes in various neoplasias of the head and neck. This study proposes to assess angiogenic activity using immunohistochemical expression by anti-CD105 and anti-CD34 antibodies in 20 cases of hemangiomas and 20 cases of oral pyogenic granulomas, in addition to determining the usefulness of these markers as one of the differential diagnosis resources for these two oral lesions. The results showed no statistically significant difference between microvascular count (MVC) means determined by anti-CD105 (p = 0.803) and anti-CD34 (p = 0.279) antibodies. The mean number of vessels obtained by MVC in the oral hemangiomas immunostained by anti-CD105 and anti-CD34 was 18.75 and 59.72, respectively, whereas in the oral pyogenic granulomas, the mean number was 20.22 and 48.09 respectively. It was also shown that CD34 was more effective than CD105 in identifying blood vessels. However, it must be pointed out that the anti-CD105 antibody seems to be more related to vascular neoformation. Overall, this assay reinforces the role of angiogenic factors in the etiopathogenesis of hemangiomas and oral pyogenic granulomas, but the results showed that angiogenesis quantification cannot be used as a differential diagnosis parameter between the two lesions analyzed

Expressão imuno-histoquímica da calponina em glândula parótida de rato após obstrução do ducto excretor principal

Glandular atrophy is one of several alterations which can aflict the salivary glands, caused generally by obstructive lesions such as sialo1ithiasis, infections or compression by neoplastic processes arnong others. In this work, a morphological and immunohistochemical study was carried out in rat parotid glands, which were submitted to obstruction of the main excretory duct suffering atrophy at varied time intervals, with the aim of appraising the behavior of myoepithelial cells during the process of glandular atrophy. It was analized the immunohistochemical expression of calponin which detects myoepithelial cells in the parotids of 28 animaIs, which were divided into 7 groups, each one made up of 4 rats, afier the ductal ligature procedure, in the following time intervals: zero hour (control), 24 hours, 7, 15, 21, 30 and 60 days. Analysis of the immunohistochemicaI profile was carried through in which the calponin expression was veritied through its distribution pattem and numericaI index. All specimens exhibited positivity for calponin in myoepithelial cells which were distributed around the acini and the ductaI structures, a small number of positiveIy marked cells being detected in the controI group and in the 24-hour group when compared to subsequent ones, where it was perceived a Iarge increase in the number of positiveIy marked cens, mainly surrounding the ductiform structures which originated during the obstruction time. Upon application of statistical tests it was verified that the rise in the number the myoepithelial positive cells for calponin, when the control groups (zero hour) was compared to the 7, 15,21, 30 and 60-day groups afier obstruction, was statistica1ly significant. It was concluded then that the detected rise probably carne about due to an elevation in the rate of proliferation of the myoepitheliaI cells subsequent to the ductal obstruction, associated with a growing resistance of these cells to glandular atrophy.

Expressão imuno-histoquímica das proteínas MMP-9, VEGF e FVW em lesões centrais e periféricas de células gigantes

Central giant cell lesion (CGCL) and peripheral giant cell lesion (PGCL) of the jaws have a distinct clinical behavior, although they share histopathologic features. It is still unclear whether these clinical differences are supported by a distinct pattern of immunoexpression of markers for multinucleated giant cells (GC) and mononuclear cells (MC). The purpose of this study was to compare the immunohistochemical expression of VEGF, MMP-9 in CG and MC and measure the vascularization by vWF to check whether there are differences in expression of these biomarkers between CGCL and PGCL. Paraffin wax blocks of 20 cases of LCCG and 20 LPCG were retrieved. MMP-9 immunoreactivity was greater in the CM of PGCL compared to VEGF (p<0.05). VEGF expression was greater in the CM of CGCL compared to PGCL (p<0.05) and it was greater in the overall expression of CGCL compared to PGCL (p<0.05). Vascularity was quantified by microvascular counting (MVC). MVC was greater in the PGCL compared CGCL (p<0.05). MMP-9 showed a greater tendency of expression in CGCL, though was not significant (p>0.05). We tested correlation between the proteins studied in each group and found a significant negative correlation between VEGF and vWF in CGCL (p<0.05). These results suggest that there are differences in the expression of VEGF in CM and overall expression between the lesions, although no statistically significant difference in the overall expression of the MMP-9. Then, there was a trend in increased expression of MMP-9 and VEGF in CGCL, possibly by the involvement of both proteins in osteoclastogenesis. Additionally, the results of this study indicate a higher degree of vascularization in PGCL compared to CGCL, fact that can be directly linked to the reactive nature of the PGCL, where the inflammatory process with its rich angiogenesis contributes significantly to these findings.

Estudo comparativo da expressão imuno-histoquímica do ki-67 em carcinoma epidermóide de língua em pacientes jovens e idosos

The squamous cell carcinoma (SCC) is the most common malignant neoplasm of epithelial origin in oral cavity and present high capacity to invade adjacent structures. Traditionally, SCC has a predominance of 50 years male patients with long-time use of tobacco and alcohol, and the tongue is the most affected anatomic site. At present, there is an increasing incidence of SCC in patients below 40 years of age, who has been exposed or not to risk factors, mainly for tongue lesions. This study aims to analyze cell proliferation index using Ki-67 antigen in SCC of the tongue for two groups of different age range: until 40 years and older than 50 years. The first group was composed by 16 patients and the second one was composed by 20 patients. Clinicopathological features of the cases were also assessed. There was a male predominance in both groups. Tobacco and alcohol habits were common for patients until 40 years (72,2%), as well as for patients older than 50 years (52,9%). The first group had statistical association with the presence of regional metastases (p = 0,036) and with the most advanced stages of the disease (p = 0,012). Considering the histological malignancy grading, there was higher incidence (56,2%) of high malignancy grade tumors in the group of patients until 40 years old, but no statistical difference has found between groups and histologic malignancy grading. Regarding the immunohistochemical expression of Ki-67, there was no statistically significant difference between the antibody expression of the groups, as well as between other clinical and histopathological parameters. This study identified no significant difference regarding cell proliferation between the analyzed groups
