Estudo clínico-laboratorial e histopatológico de cães naturalmente infectados por Leishmania chagasi com diferentes graus de manifestação física

Canine Visceral Leishmania (CVL) is an important zoonotic disease that has a world wide distribution and has a large impact on public health on the American Continent, especially in Brazil, where the nature of endemic diseases in humans affects a large part of the nation. The influence of the prevalence of CVL in the increased rate of human cases in endemic areas and in the unleashing of epidemic outbreaks shows the need for a more profound understanding, that would generate significant advances in the current measures used to control the reservoirs of sickness that are practiced by the Programa Nacional de Vigilância e Controle da Leishmaniose Visceral. The present work describes and compares the clinical-laboratorial and histopathological findings of twenty-three dogs that were naturally infected by Leishmania chagasi, from endemic areas in metropolitan Natal, Rio Grande do Norte, Brazil. These animals, that were selected and given physical and serological exams (IFI and ELISA rK-39), were classified according to the degree of clinical severity and had blood samples drawn (whole blood and serum) for a complete hemogram and a coagulogram to be done as well as biochemical tests for kidney and liver function. The confirmation of infection by L. chagasi was done after the euthanasia of the animals, through the direct demonstration of the parasite in the impression of the spleen and liver crowned with GIEMSA and through a cultivation by means of NNN/Schneider. According to the clinical evaluation, the animals were classified as asymptomatic (7), oligosymptomatic (7) and polysymptomatic (9). Among the animals that were chosen to be autopsied, there were 2 asymptomatic, 3 oligosymptomatic and 3 polysymptomatic, for the purpose of studying their histopathology, having collected fragments of the spleen, liver, kidneys and skin and were fixed in 10% tamponed formol. The comparison between the average parameters of the clinical-laboratory tested animals in the groups was done through the Student t test (a<0.05). The main clinical signals observed were lymphadenomegaly, alopecy, dermatitis, exfoliation, cutaneous ulcers, onicogriphosis and emaciation. The main clinical-laboratorial alterations established, mainly in the polysymptomatic group, were anemia, hyperproteinemia, hyperglobulinemia, alterations in the albumin/globulin ratio and increased ALT activity. Renal alterations were not verified (urea and creatinine levels were normal). Thrombocytopenia was observed in three clinical groups. However, the other indicators of coagulation function (TAP and TTPA) did not have abnormal variations. There were inflammatory infiltrations and leishmania amastigotes in the skin of polysymptomatic dogs, however, they were not found in the skin of asymptomatic animals. Hypertrophy and hyperplasia of the phagocyte mononuclear system, leishmania amastigote parasites were found in the macrophages, extramedullary hematopoiesis and degenerative alterations were detected in the spleen and liver of 8 of the animals submitted to histopathological exams. In accord with these results, it was demonstrated that the expected alterations in the hematological and biochemical parameters in function of their viscerotropic nature of CVL are mainly observed in the more advanced stages of the disease. The absence of inflammatory infiltration and parasite load in the skin suggest that infected animals without symptoms may have an importance irrelevant to the infectiousness of the vector

Poéticas de um saber brincar: a vez e a voz do fandango

The present thesis aims to get to know and to analyze the elements which make up the poetical performance of the Fandango from Canguaretama confirming/corroborating an eminently theatrical model. It still highlights the producers´ history, its asset production and its insertion in community where we had contact with two other types of performances: the daily and the ritualistic. Such actions both combine and present different meanings and objectives, promoting distinct readings and experiences. Looking at these three ways of performances poetic, daily, and ritual enabled to go deeper in cultural aspects of the studied community and, thus, check over what is going on in these events, how they accord with and conceive a popular performance context. The research could substantiate the existence of a theatrical model whose performance by means of the voice and active presence of playful bodies, implied in getting to know the consolidation of a cultural patrimony which reveals us the past, but, especially, the present, its people and its place

A construção do princípio do cooperação na Pedagogia Freinet:uma prática em sala de aula do ensino fundamental

Cette recherche est ancrée dans les racines de la pédagogie de Célestin Freinet, un des plus importants éducateurs du XXème siècle, car ses propositions naissaient de la réalité de l élève lequel était, de ce fait, valorisé. Au début de ses recherches, Freinet s est rendu compte que pour pouvoir édifier une école qui, effectivement, atteigne les classes populaires, il devrait réaliser des changements dans le milieu scolaire. Notre travail le principe de coopération dans les actions développées par le professeur et ses élèves dans le quotidien de la salle de classe. Les décisions pour la réalisation de ce travail ont exigé, de notre part, une profonde et globale réflexion vis à vis des pas qui devraient être entamés, considérant que notre intention n était pas de faire une simple intervention dans le système scolaire avec une programmation pré-établie, sans instruments crées à priori pour le développement d actions dans le contexte scolaire. Comme questions principales nous pouvons souligner: Comment la coopération contribue pour le vécu des élèves? De quelle manière ce principe se réalise dans le quotidien de la salle de classe? Le principe coopératif, pourrait-il agir comme une alternative qui favorise la dynamique de la salle de classe et des relations entre les élèves? Le principe de la coopération exige la création d une ambiance en salle de classe dans laquelle il existe des éléments médiateurs dans la relation professeur-élève. Ainsi, l organisation de la salle a un caractère important; il faut considérer la participation des élèves dans la construction de ses connaissances. Pour cela, il est nécéssaire créer des structures qui doivent être complétées à partir de l activité des propres élèves. Dans la ligne de cette pensée nous avons, donc, comme objectifs spécifiques: 1) Investiguer, dans l action pédagogique du professeur, l utilisation de stratégies pour la consolidation du principe coopératif pour la salle de classe; 2) Faire une réflexion à propos de l organisation du travail coopératif développé par le professeur en observant comment celui-ci est réalisé en salle de classe; 3) Établir un répertoire des vécus de coopération construits en salle de classe par les élèves et le professeur. Ainsi, pour développer une interaction avec les sujets de la recherche [professeurs et élèves] des études ont été développés ancrés sur les principes de la recherche qualitative de type ethnographique pour considérer ce dernier un référentiel méthodologique plus indiqué à l utilisation des téchniques d observation, interviews et analyse de documents, car ces téchniques sont, traditionnellement, associées à l ethnographie. Cette recherche a pour but comprendre la vision de ce qui arrive quotidiennement dans la salle de classe observée et les multiples relations imbriquées dans le processus de motivation de l apprentissage utilisant la coopération

O sofrimento do paciente na UTI : escutando a sua experiência

In tertiary care, the Intensive Care Unit (ICU) is nowadays one of the most complex settings in providing care to critically ill patients and could make the difference in favor of life. Nevertheless, the stigma of death which pervades the imagination when the ICU is mentioned and the excessive importance placed on machines rather than on the human being end up by causing distress to some extent. As the purpose of this investigation is to understand the distress caused to a patient in an ICU, it has been grounded on the following question: What kind of distress does a patient go through during his/her experience in an ICU? This study has, therefore, an analytical and reflexive character embedded in a qualitative dimension of a phenomenological approach based on narratives. To this purpose, five patients were interviewed from November to December 2008. Out of the empirical material gathered from these narratives we were able to identify several factors that cause distress to ICU patients. Among them were: the certainty that they are critically ill and fear death, a closed room, too much lighting, a typical loneliness arising from being isolated from family members and dear ones, lack of communication with the professional staff, and noise; besides having to undergo therapeutic procedures. In summary, although the ICU is seen as a place of distress, in many aspects and in accord with this research, such distress can and should be relieved. On the other hand, being near to death leads them to a redefinition of life, said the patients.

A eletricidade chega à cidade: inovação técnica e a vida urbana em Natal (1911-1940)

Dans les premières décennies du XXème siècle, un groupe d intellectuels brésiliens a pris pour soi la mission de conduire la nation aux chemins du progrès, en réfléchissant sur les transformations des villes et, souvent, en proposant et en mettant en avant des actions et mesures qui dirigeraient la modernisation du pays. Dans ce contexte, la ville apparaissait comme un synonyme de progrès en opposition à la campagne, en donnant emphase à la construction du Brésil urbain. À Natal, celui-ci a été une période de sensible modification dans l espace urbain, en suivant les préceptes de l hygiénisme et de l esthétique racionaliste, qui ont orienté les réformes entreprises dans beaucoup de villes brésiliennes. Les élites politiques et socioéconomiques de la capitale du Rio Grande do Norte ont developpé le discours en faveur de la modernisation qui avait pour objectif de justifier les interventions dans la ville et l introduction de l infra-structure de services urbains, par exemple, les services d illumination et de transport, qui à partir de 1911, ont commencé à être stimulés par l électricité. Cette modernisation est matérialisée par de nouveaux équipements et services, par des espaces remodelés en accord avec la rationalité technique de l urbaniste, pour l utilisation de nouvelles sources d énergie (gaz, électricité), en plus de la croissance de la population résidente en ville. Cependant, nous ne pouvons pas oublier que la construction de la ville moderne est passée tant par des transformations physiques, matérielles, comme par l absorption de valeurs, symboles, gestes, vocabulaires, objets, adoptions de nouvelles normes de comportement et par la formation de nouvelles sensibilités sur l espace urbain et la vie en ville. De cette manière, les nouvelles normes technologiques, comme l électricité, ont rendu possible des transformations dans la structure matérielle de la ville et en vie urbaine dans ses plus divers aspects. Ce travail propose d analyser la relation entre énergie électrique et la vie urbaine à Natal entre 1911 et 1940, en prenant en compte, pour cela, les actions d intervention de l État sur l espace urbain et les perceptions d intellectuels face aux transformations urbaines dont ils étaient les témoins. À partir de cette analyse, nous cherchons à préciser les efforts gouvernementaux pour la manutention des services d électricité et conservation des équipements urbains; comprendre comment l utilisation d énergie électrique a aidé à produire de nouvelles situations quotidiennes et comment elle a été perçue, traduite en sentiments et perceptions fondées dans la cohabitation avec cette innovation technique. Les élites locales désiraient diffuser des habitudes considerées modernes, en construisant une identification avec la manière de vie urbaine, fortement inspirée dans la vie dans les villes Européennes et Américaines. L électricité a rendu possible des expériences et sensations qui allaient caractériser l habitant de la ville

Preferências e escolhas românticas entre universitários

Several studies have found different patterns of preferences to men and women for short term and long term relationship romantic partners. It is known that the preferences vary with the sex of individuals, the expected involvement level of the relationship and according to the perceptions that subjects have about themselves. In the present study, we investigate whether the preferences typically founded for sexes are also founded between Brazilian undergraduate students. We also investigated if the individuals choose partners in accord of the sex preferences and if the ideal preferences are really expressed in real choices. For these investigations, 370 undergraduate students described profiles of an ideal partner for a short-term and a long-term relationship, through the joint evaluation of nine characteristics. Each ideal s profile has been described over three simulations, in which the amount of points available to be invested were limited and gradually reduced. After the descriptions of these profiles, the participants described the current or previous partner (if they were not in a relationship) and performed a self-assessment with the same characteristics used in the description of preferences. Overall, the results obtained in several countries were observed in Brazil. For short-term relationships men prioritize physical attributes and women value physical and personal attributes. For long-term, personal traits gained in importance on masculine preferences and women emphasized personal traits and the partner disposition to acquire resources. We also identified similar preferences profiles for both sexes and that the romantic preferences reflect similarities with the own individual s characteristics, in addition to the typical sexual preferences expected for the Parental Investment Theory. When evaluated their real partners, men considerate them more physically attractive than themselves but less intelligent, good humorous and ambi tion/willing to work. Women, in turn, described their partners as good as them. Finally, we observed equivalence between characteristics of the subjects and those of its partners, this effect being more pronounced among men. The last partners were described only as less sincere. The interpretation of the most part of our results was possible from evolutionist s and socio-cultural s explanations and was discussed under the two perspectives. We conclude this study stressing that the traditional romantic preferences occur in Brazil and that the sex, the kind of relationship and the vision that people have about their own characteristics affect the preferences, which are expressed in the real partner choices

Zoneamento ambiental do Município de Aquiraz-CE

The Metropolitan Region of Fortaleza (RMF) is composed by thirteen cities, where is call the attention of Aquiraz. The city has a excellent resort area and a big importance in socioculture and historics aspects. It was one of the first village of Ceará, and it was founded in 1699, with was also the capital of the state until 1726. The urban local development has been disorganized in the last decades, the fact is, insert of turismon in its coast, and it is unable with alow capacity of the natural suppots, configuring unsustainable and et environment ambience. Considering as a turistic region, it is preoccupy, been necessart to create a better control of the nature of the region by the users. The environmental zoning in this work it is to plan of adequate form the use of the ground based in the management of the interests and the social and economic necessities in accord with the preservation of the environment and the natural characteristics of the city. The same is one great instrument planning where use to be analized in differents ways: social, ambiental, economical and institucional, and promove alternatives of use and occupation of the land to recreate the city. The methodo used to get the real objective, englobed zonal maps in ambiental unities and others themes (geologic/geomorphologic) since than the images from satelities LANDSAT and SPOT and fotografies under position of maps, secundaries listes gets in publics department, bibliographie, informations by the local populations. This prociduries mede easy to create maps, geologic/geomorphologic, of use and occupation the earth and the environmental zoning to analize the dynamic and the working of each ambiental unity of the city Aquiraz wich is located by map of this job. As a result of this job was confectionated the environmental zoning map of Aquiraz wich was divided in five ambiental unities and restrictions areas of occupation: unit I Littoral Plain (zoning with serious restrictions to the occupation); unit II Sub-Littoral Plain (improper zoning to the occupation); unit III between tray zoning Pré-Littoral and Peripheral Depression (improper zoning to the occupation); unit IV Strativism reserve of the plug (zoning used more under control in its occupation) and unit V Fluvial Plain Localities of the Indians Jenipapo-Kaninde/ locality Quilombolas (zoning used more without official regulation). With proposal in the ambient units above one expects that it has a reduction of the ambient degradation and protection of the local biodiversity of the city of Aquiraz in the State of the Ceará
