Labbate, Rogério;Lehn, Carlos Neutzling;Denardin, Odilon Victor Porto;
Revista Brasileira de Otorrinolaringologia , 2003, DOI: 10.1590/S0034-72992003000300009
Abstract: the radiotherapy in patients with neoplasias of head and neck causes alterations in the oral mucous membrane interfering with the therapeutic execution and the final result. aim: to evaluate the protective effect of the chlorhexidin on the oral mucous membrane, during the radiotherapy and its reflex in the quality of life referred by patients. study design: clinical prospective. material and mathod: 21 patients with cancer of head and neck were selected and allocated in two groups: group placebo (n=11, 9 men and 2 women, mean age 58 years) distilled water - two daily mouthwashes and group medication (n=10, 7 men and 2 women, mean age 52 years) chlorhexidin 0,12% - two daily mouthwashes. the patients were appraised weekly with local exam for detection of the mucous membrane alterations (classification in agreement with who and group of therapy for radiation in oncology - degrees 0 to iv) and completion of questionnaire of life quality emphasizing the pain aspects, appetite, palate and alimentary habits. the statistical analysis accomplished by fisher's exact test. results: the graduation of mucositis was more intense in the group placebo in 6 of the 10 weeks of evaluation. the frequency and intensity of pain were worse in the group placebo in the 4th week of radiotherapy and the palate modification was more intense in the individuals that didn't use the medicine just in the 7th week. they were not found differences in the other parameters of life quality. conclusions: we can conclude that the chlorhexidin didn't eliminate the mucous membrane lesions but decreased, significantly, their harmful effects and intensity without presenting a persistent reflex in the quality of the patients' life.

Abstract: A radioterapia em pacientes com neoplasias de Cabe a e Pesco o causa altera es na mucosa oral comprometendo a execu o terapêutica e o resultado final. OBJETIVO: Avaliar o efeito protetor do gluconato de clorexidina, sobre a mucosa oral, durante o tratamento actínico fracionado e o seu reflexo na qualidade de vida referida pelos pacientes. FORMA DE ESTUDO: Clínico prospectivo. MATERIAL E MéTODO: Foram selecionados 21 portadores de cancer de Cabe a e Pesco o alocados em dois grupos: grupo Placebo (n=11, 9H e 2M, idade média 58 anos) água destilada - dois bochechos diários e grupo Medica o (n=10, 7H e 2M, idade média 52 anos) gluconato de clorexidina a 0,12% - dois bochechos diários. Os pacientes foram avaliados semanalmente com exame local para detec o das altera es de mucosa (classifica o de acordo com a WHO e Grupo de Terapia por Radia o em Oncologia - graus 0 a IV) e preenchimento de questionário de qualidade de vida ressaltando os aspectos de dor, apetite, paladar e hábitos alimentares. A análise estatística realizada pelo teste exato de Fisher. RESULTADOS: A gradua o da mucosite foi mais intensa no grupo Placebo em 6 das 10 semanas de avalia o. A freqüência e intensidade das dores foram piores no grupo Placebo na 4a semana de radioterapia e a modifica o de paladar foi mais intensa nos indivíduos que n o usavam o medicamento apenas na 7a semana. N o foram encontradas diferen as nos outros parametros de qualidade de vida. CONCLUS O: Podemos concluir que o gluconato de clorexidina n o eliminou as les es de mucosa mas diminuiu, significativamente, os seus efeitos deletérios e intensidade sem apresentar um reflexo persistente na qualidade de vida dos pacientes.
Local and regional richness and rarity of leaf-litter ants: An overview from spacial scale in neotropical region  [PDF]
Manoel Fernando Demétrio, Rogério Silvestre
Open Journal of Animal Sciences (OJAS) , 2013, DOI: 10.4236/ojas.2013.32A002
Abstract: An unusual approach about richness and rarity of leaf-litter ant species is presented here from a dry forest reminiscent in Pantanal province (Chacoan subregion) suggesting the boundaries that defining local and regional scales for this particular ant community. We analysed the frequency of distribution of 170 ant species collected on 262 Winkler’s samples along Serra da Bodoquena National Park, Mato Grosso do Sul state, Brazil and described some ecological mechanisms that made the species richness estimates be highly influenced by species with low frequencies of records in an extent regional of a pristine dry forest. Bayesian inference was conducted to provide if the probability of latitudinal gradient was correlated with the species richness to define alpha diversity.

Cidade, subjetividade e território: representa??es de moradores de favelas
Lopes, José Rogério;
Intera??es (Campo Grande) , 2007, DOI: 10.1590/S1518-70122007000100009
Abstract: the article presents an analysis of the relation between space, subjectivity and knowledge based on an ethnographic study developed in a slum pertaining to the town of ubatuba, in the state of s?o paulo, brazil. the analysis is centered on the discussion of terms that define social-spatial perceptions among impoverished subjects, analyzing the social content that permeates the use of such terms and that makes it possible to characterize distinctions to the analysis of social-spatial relations that are marked by social inequality.
A economia clássica contra os fatos ou Sismondi entre os ricardianos
Arthmar, Rogério;
Economia e Sociedade , 2009, DOI: 10.1590/S0104-06182009000200002
Abstract: this paper deals with the debate which opposed sismondi and the ricardian economists, in the first half of the nineteenth century, on the equilibrium of markets, the role of competition and the effects of machinery in industrial societies. at the initial section, the main content of sismondi's critical rhetoric toward the classical orthodoxy is reconstituted. after that, the replies of mcculloch and colonel torrens are detailed, specially their defense of free competition and the unlimited character of demand, as well as of the inroads of machinery in the productive process. the third part considers sismondi's rejoinder when he reinforces his theory of a general glut from a historical perspective of capitalism. in the end, and having in sight this particular controversy, a brief assessment of ricardo's legacy to political economy is made.
Por um novo conceito de comunidade: redes sociais, comunidades pessoais, inteligência coletiva
Costa, Rogério da;
Interface - Comunica??o, Saúde, Educa??o , 2005, DOI: 10.1590/S1414-32832005000200003
Abstract: this text essentially deals with the transmutation of the concept of "community" into "social networks". this change is due largely to the explosion of virtual communities in cyberspace, a fact that generated a number of studies, not only on this new way of weaving a society, but also on the structural dynamics of communication networks. at the core of this transformation, concepts such as social capital, trust and partial sympathy are called upon, so that we may think about the new forms of association that regulate human activity in our times.

Abstract: studies for investigation of new therapeutic modalities in tumoral biology should be based on previous experimental studies. then, there are a great variety of tumoral experimental models today. some investigations have been done necessary an adaptation of the tumoral model to the needing of the studies biological and pathological. so, in our laboratory, we looked for a tumoral hepatic model for experimental studies with the following characteristics: easy manipulation, control of growing, evolution and aggressiveness like to humans. data of the literature took us the search of the hepatic tumor vx-2, in rabbits. in this article we discussed the advantages of use this experimental model and its introduction in our country. experimental hepatic tumor (vx-2) in rabbit. implantation of the model in brazil.
Antropologia, educa??o e condicionamentos culturais: pensando as media??es no processo de socializa??o escolar
Lopes, José Rogério;
Educar em Revista , 2009, DOI: 10.1590/S0104-40602009000100012
Abstract: the present article addresses the path that the relation between anthropology and education in brazil has taken, naming the anthropologists' concerns towards the study of education. research on this area has turned evident the change in the contexts of cultural diversity, which previously used to focus on subjects and on isolated or less integrated groups, and now points to a place of cultural diversity that replicates itself precisely through the integration of those very same subjects and groups to the model of western development and on the institutional relationship in which the various categories of subjects are today conditioned. the purpose of such new situation, where cultural conditioning, which are traditionally formed in ways of life that hardly communicate, start to establish a speed economy of material and symbolical trades, is still on sketch. however, it is possible to presently discuss the character of the mediations at stake in the institutional relationship, trying to recognize the elements that are important for the analysis of new conditioning movements operating today on the school education. following this line of thought, this article presents a review of the mediation category, according to raymond williams' theory, in order to discuss the structural changes that contemporary society has endured, along with the unfolding in the socialization process (or institutionalization). such review focus primarily on the changes that affect the effective mediation in this process for and through the school.
Notas em torno de retratos de crian?a
Fernandes, Rogério;
Educa??o e Pesquisa , 2000, DOI: 10.1590/S1517-97022000000100007
Abstract: by highlighting the polysemic character of the word ?child?, this paper questions such polysemy in past times. the paper asserts that the word ?child? has many times been substituted by others with the purpose of designating more properly the phases of the child development. by doing that, the classic study by philippe ariès about the feeling of childhood during the middle age is questioned. the analyses start from a re-reading of the chronicle of d. jo?o i, by fern?o lopes, and it traces in the author?s text the words used to denote ?child? in its current meaning. the paper?s objective was to investigate one of the works of this great author of the portuguese language in the period studied. besides lopes? work, some other pages of the literature that present the child in different situations were also examined. the analyses allowed the reconstruction of various representations of children that revealed significant facets of the portuguese pedagogical thinking as regards ways of conceiving the childhood. the paper concludes by arguing for the need of a plural understanding of the term childhood. the plurality would signal to various profiles that this historical, social and psychological category allows. the study also calls attention to the fact that the portraits of children have not come directly from the children themselves but they have been made by those that were no longer children.
