CERNE , 2011,
Abstract: The major objective of this work was to identify and quantify forest fragments suitable to be used as private protected land in rural properties located in the S o Bartolomeu creek watershed, State of Minas Gerais, Brazil. The methodological procedures included: mapping of 78 forest fragments through the visual interpretation of an Ikonos II satellite image; delineation of Permanent Preservation Areas (PPAs) from a hydrographically conditioned digital elevation model and mapping of 292 rural properties through interviews with owners, with the aid of a printed Ikonos II image. The generated maps were overlapped (crossed), allowing the identification of forest fragments that could be used as private protected land in rural property. The result indicated that, from the total of properties evaluated, only 41 (14.04%) have more than 20% of forest cover, and therefore, are in condition to attend the environmental law for private protected land.

Abstract: from march 1981 to march 1988, 2324 bioprostheses were implanted in 2016 patients in 5 centers in the state of minas gerais. this study includes only the analysis of patients undergoing isolated aortic (n = 603) or mitral (n = 1110) valve replacement. the hospital mortality in this group (n = 1713) was 104 patients (6.1%). from the remaining 1609 patients, that were discharged from the hospital, we were able to obtain a follow-up in 1101 or 64.3%. this analysis related to a period ranging from 1 to 84 months, mean = 48 and a cumulative follow-up in the aortic group (n = 385) equal to 1230 patients/year; the mitrals (n = 716) equal to 3018 patients/year. there were 102 late complications in 716 patients (14.24) and 51 in the aortic group (13.2). in relation to the age or the patients, 220 were under 20 years of age (mitrals = 176/aortics = 44) and in this subgroup the intrinsic valve failure was 43% of the mitral patients and 29% of the aortic group. the prosthetic endocardite was more frequent in the aortic group (45%) in compararison with the mitrals (29.7%). there were 62 reoperations in 1101 patients, with hospital mortality of 12.6%. the reoperations were more frequent in the mitral group, in patients below 20 years of age. survival, considering only deaths related to the bioprosthesis, was 97.1% (32/1101). in the aortic group, 96.9% of patients were free of valve disfunction at the end of 7 years; among the mitrals, 95.2%. the major incidence of valve failure was encountered in the mitral patients, below 20 years of age; 85.3% were free of this complication at 7 years of follow-up. at the end of this study, the majority of the alive patients was functional classes i and ii of the nyha. although the incidence of reoperation is significant, these findings are acceptable, specially because bioprosthesis offers a safer alternative than mechanical prosthesis. the present results suggest the continuation of research to obtain the ideal bioprosthesis, although current
Basta implementar inova??es nos sistemas educativos?

Abstract: the paper presents references to better understand the implementation of changes at schools. systematization of the references is based on a study about the reform of the spanish education system and the implementation of a national curriculum in england and wales, as well as on reviews of researches developed in that field. the reform of the spanish education system attempted to balance the prescriptive character of the general guidelines with the more open approach of leaving each school to elaborate its own curricular proposal (taking into account its social context and the general guidelines). the study of the spanish reform has contributed mainly to make explicit the diversity of viewpoints and attitudes that emerge within the context of an educational innovation. such diversity is presented and summarized in the form of six different tensions. the implementation of the national curriculum in england and wales aimed to establishing a greater control upon schools through a detailed and prescriptive curriculum, associated to the use of external exams as instruments of evaluating schools by the performance of their students in the exams. in this case, analyses are grounded on various research data. those studies point to disastrous results in the educational context, with the impoverishment of pedagogical practices where activities targeted at the exams take priority. after using these two experiences to motivate the description of the references, the paper concludes by proposing that we should go beyond implementing innovations, toward processes of professional and institutional development that enable schools to produce proposals and contexts of change, and to interact critically with them.

Abstract: Este artigo apresenta referências para melhor compreender a implementa o de mudan as na escola, sistematizando-as a partir de um estudo sobre a Reforma do Sistema Educativo na Espanha e a implanta o de um Currículo Nacional na Inglaterra e País de Gales, conjugado a revis es de pesquisas desenvolvidas nesse campo. A Reforma do Sistema Educativo espanhol tentou equilibrar o caráter prescritivo de diretrizes gerais com o caráter aberto da atribui o de cada escola elaborar sua proposta curricular, a partir de seu contexto e no marco das diretrizes propostas. Seu estudo contribuiu, sobretudo, para explicitar a diversidade de vis es e posicionamentos que emergem do contexto de uma inova o. Essa diversidade é sintetizada na forma de seis diferentes tens es. A implanta o de um Currículo Nacional na Inglaterra objetivou estabelecer um maior controle sobre a escola por intermédio de um currículo detalhado e prescritivo, associado à aplica o de exames externos como instrumentos de avalia o da escola por meio do desempenho dos alunos nos testes. No caso da experiência inglesa, s o expostas análises fundadas em um conjunto diversificado de dados de pesquisa. Essas pesquisas apontam resultados desastrosos no contexto escolar, com o empobrecimento da prática pedagógica, predominando atividades preparatórias para os exames externos. Apresentadas as referências, a partir do substrato proporcionado por essas duas experiências, o autor conclui propondo ir além da perspectiva de implementar inova es em dire o a processos de desenvolvimento profissional e institucional, que constituem, na escola, uma maior capacidade de produzir e interagir criticamente com propostas e contextos de mudan a.

Rocha, Luciane de Melo;Moreira, Lilia Maria de Azevedo;
Jornal Brasileiro de Patologia e Medicina Laboratorial , 2007, DOI: 10.1590/S1676-24442007000100006
Abstract: objectives: to evaluate the laboratories methods of the oculocutaneous albinism (oca 1and oca 2) of descriptive form and to analyze its results. methods: the hair bulb test is a chemical method used to distinguish the two forms, however, recently had its effectiveness as an standard test contested. the advance of molecular biology allows the analysis of the mutations that cause the disturb and its genic location. conclusions: the bulb test is secure only for the diagnosis of oca 1a, being able to be used as complement of a more refined method. the molecular analysis supplies a diagnostic definitive allowing to distinguish oca 1 from oca 2, because the mutations affect genes in different chromosomes.
Skin Delivery of Glucosamine and Chondroitin Sulphates—A Perspective on the Conservative Treatment for Osteoarthritis of the Knee  [PDF]
Cláudia Batista Siqueira Leite, Janaína Moreira Coelho, Luis Alexandre Muehlmann, Ricardo Bentes de Azevedo, Marcelo Henrique Sousa
Journal of Biosciences and Medicines (JBM) , 2017, DOI: 10.4236/jbm.2017.54002
Abstract: Based upon a series of research studies, scientific organizations considered Glucosamine and Chondroitin “not appropriate” as osteoarthritis (OA) of the knee modifying drugs and uncertain as pain relievers. Research studies which served as foundation for the aforementioned conclusions focused on the oral use of the substances. On the other hand, studies recommend that topical administration in treating OA be considered first line therapy, since it is said to be advantageous for its efficacy in treating localized situations, as it allows greater local concentration and it results in smaller systemic effects. Studies found did not provide sufficient evidence for good development and application strategies and were not enough to prove the technique to be effective or non-effective. Several other aspects must be clarified. In order to enhance permeation and delivery of Glucosamine and Chondroitin to knee joint, combining the advantages of intravenous infusion therapy with the convenience of oral administration, the suggested course of action is to transform skin delivery technology, while clarifying other points discussed throughout this research study.
Fisheries and conflicts in Guanabara Bay, Rio de Janeiro, Brazil
Jablonski, Silvio;Azevedo, Alexandre de Freitas;Moreira, Luiz Henrique Arantes;
Brazilian Archives of Biology and Technology , 2006, DOI: 10.1590/S1516-89132006000100010
Abstract: despite the magnitude of domestic and industrial pollution, fishery yield registered in several landing points at guanabara bay, between april 2001 and march 2002 was slightly over 19,000 tons, corresponding to a value of us$ 4.8 million. when considered only the fish directed to the food market, the total catch amounted to about 6,300 tons and a value of us$ 3.7 million. only a few fish species reached expressive densities compatible with commercial fisheries. among small pelagic fish, atlantic anchoveta and brazilian sardinella were the dominant species, while in terms of demersal fish, croakers, mullets and catfishes comprised the main part of the catch. the absence of landing data previous to the spilling of 1.3 million liters of oil in january 2000 led to claims by fishermen representative organizations of values corresponding to about 50 years of fish harvest in the bay. possibly, a data collection network could be established in a participative way with the main fishermen local associations. the relatively stabilized fisheries in the bay suggested that reasonable inferences could be made, without, necessarily having a complete coverage of all landing points.

Hennington, élida Azevedo;Cordeiro, Ricardo;Moreira Filho, Djalma de Carvalho;
Cadernos de Saúde Pública , 2004, DOI: 10.1590/S0102-311X2004000200031
Abstract: in this epidemiological study, deaths resulting from external causes in 1999 and 2000 among males (age 15-64 years) in campinas, s?o paulo state were analyzed through interviews with their relatives. we attempted to correlate this incidence with individual occupational history, allowing the characterization of these events as work-related injuries. the proportional death rate due to work-related injuries was estimated at 27% in this group. none of the death certificates we analyzed had "yes" specified in the appropriate work-related injury field. based on these results, official data from the brazilian ministry of labor on the number of deaths resulting from work-related injuries in this period in the state of s?o paulo is underestimated by 83.4%. the vast majority of fatal work-related injuries were homicides and traffic accidents, reflecting an increase in violence in this brazilian city.

Abstract: Neste estudo epidemiológico foram analisados óbitos decorrentes de causas externas, ocorridos nos anos 1999 e 2000 entre moradores masculinos da Cidade de Campinas falecidos com idade entre 15 e 64 anos, por intermédio de entrevistas com familiares. Buscou-se correlacionar esta incidência com a história ocupacional dos indivíduos, permitindo a caracteriza o de tais eventos como acidentes de trabalho. A mortalidade proporcional devido a acidentes de trabalho foi estimada em 27,0% neste grupo. Em nenhuma das Declara es de óbito analisadas estava assinalado com "sim" o campo Acidente de Trabalho. Com base nos resultados, estimou-se que a informa o oficial do Ministério do Trabalho e Emprego sobre o número de óbitos decorrentes de acidentes de trabalho no período no Estado de S o Paulo esteja subestimada em 83,4%. Constatou-se ainda que a imensa maioria dos acidentes de trabalho fatais identificados era de homicídios e acidentes de transporte, refletindo o aumento da violência nas grandes cidades brasileiras.
