Identifying important endemic areas using ecoregions: birds and mammals in the Indo-Pacific

Concentrations of large numbers of endemic species have been singled out in prioritization exercises as significant areas for global biodiversity conservation. This paper describes bird and mammal endemicity in Indo-Pacific ecoregions. An ecoregion is a relatively large unit of land or water that contains a distinct assemblage of natural communities. We prioritize 133 ecoregions according to their levels of endemicity, and explain how variables such as biome type, whether the ecoregion is on an island or continental mass, montane or non-montane, correlate with the proportion of the total species assemblage that are endemic. Following an exploratory principal components analysis we classify all ecoregions according to the relationship between numbers of endemics and overall species richness. Endemicity is negatively correlated with species richness. We show that plotting the logit transformation of the endemicity of birds and mammals against log of species richness is a more effective and useful way of identifying important ecoregions than simply ordering ecoregions by the proportion of endemic species, or any other single measure. The plot, divided into 16 regions corresponding to the quartiles of the two variables, was used to identify ecoregions of high conservation value. These are the ecoregions with the highest endemicity and lowest species richness. Further analysis shows that island and montane ecoregions, regardless of their biome type, are by far the most important for endemic species.

CD4(+) CD25(+) Foxp3(+) Regulatory T Cells, Dendritic Cells, and Circulating Cytokines in Uncomplicated Malaria: Do Different Parasite Species Elicit Similar Host Responses?

Clearing blood-stage malaria parasites without inducing major host pathology requires a finely tuned balance between pro- and anti-inflammatory responses. The interplay between regulatory T (Treg) cells and dendritic cells (DCs) is one of the key determinants of this balance. Although experimental models have revealed various patterns of Treg cell expansion, DC maturation, and cytokine production according to the infecting malaria parasite species, no studies have compared all of these parameters in human infections with Plasmodium falciparum and P. vivax in the same setting of endemicity. Here we show that during uncomplicated acute malaria, both species induced a significant expansion of CD4(+) CD25(+) Foxp3(+) Treg cells expressing the key immunomodulatory molecule CTLA-4 and a significant increase in the proportion of DCs that were plasmacytoid (CD123(+)), with a decrease in the myeloid/plasmacytoid DC ratio. These changes were proportional to parasite loads but correlated neither with the intensity of clinical symptoms nor with circulating cytokine levels. One-third of P. vivax-infected patients, but no P. falciparum-infected subjects, showed impaired maturation of circulating DCs, with low surface expression of CD86. Although vivax malaria patients overall had a less inflammatory cytokine response, with a higher interleukin-10 (IL-10)/tumor necrosis factor alpha (TNF-alpha) ratio, this finding did not translate to milder clinical manifestations than those of falciparum malaria patients. We discuss the potential implications of these findings for species-specific pathogenesis and longlasting protective immunity to malaria.

Diagnóstico das micro e pequenas empresas da cadeia produtiva moveleira da serra gaúcha : importância para o desenvolvimento setorial

The increasing of afluence demands the companies to be competitive and have a deep knowledge about the area wich they are participating. Through the search of management and produtive information, and the analisys of internal and external information, the company could identify strong and weak points , threats and oportunities, alowing the obtaince of competitive advantages. This research shows the result of a close search study about the usage of strategic planning and management technics, setting in evidence the necessity of micro and small furniture companies and furniture supply chain, represented in this case by sub-contract companies. Still looking to accentuate the importance that this study will represent to the setorial development, specially to the furniture companies wich have a big importance due to the report of small utilization of management technics in the sub-contract companies. Through analisys, it was possible to find out some common caracteristics in all 171 conmpanies evaluated, wich are showing likely 'sinalization', such as: - lower level os scholarship (96,5% elementary school, 3% until high school, 0,5% university/college graduration); - external market from Brazilian MPE¿s (5% export products to Mercosul and just 1% export products to Latin America, absenting exportations to other markets); - carefree with modern technics of management, certificates ISO 9000, 14000, MRP, CQT, among others; - carefree with strategic planning; - lower utilization of operacionl procedures, rules and function description; - ignoring the participating of market; - lower utilization of human resources index as a management form; - Small utilization of costs tabs (31%), with a small informatization level (8%) and apllying with non-management form; - low utilization of quality statistics (4%), re-working index (9%), among others. In syntesis, the basis expose that the great marjority of companies don¿t have knowledge about planning and the modern technics of management.

A politica fiscal no Brasil : limites e contradições : o caso do Estado do Espirito Santo

o estudo pretende contribuir para a análise da realidade brasileira, através do caso do Estado do Espírito Santo, no período compreendido entre 1946 a 1980, tentando demonstrar a dependência financeira dos governos estaduais refletida na perda de receitas próprias e da necessária autonomia para a sua utilização. Numa visão retrospect.iva observa-se uma excessiva tendência à centralização manifestada pelo federalismo brasileiro, principalmente, depois da Reforma Tribut.ária de 1967, que estabeleceu um rigoroso controle da União sobre as receitas tributárias e sobre a ação dos Estados- membros, reduzindo sua autonomia em matéria de legislação tributária. A centralização financeira e política fez com que os go- . , . vernos estaduais perdessem 8S prerrogativasanteriorrnente adquiridas e tivessem limitada sua autonomia em;matéria de politica fiscal. Tentou-se compensar a acentuada redução das receitas tributárias estaduais lnstituindo- se o mecanismo das transferências que, a despeito de suas funç5es redIstributi vas, impõe uma série de exig§ncias e determinações para a sua aplicação. A partir dessa constataç50 passa-se a analisar a política fiscal no Estado do Espírito Santo observando-se as administrações estaduais nesse período. Cheg~-se à conclusão de que as sucessivas crises financeiras ocorridas limitaram a formulação de uma política fiscal estadual. Com isso, constat3-se que os estados passaram a ser rneros agentes administrativos reproduzindo as decis5es maiores formuladas pelo governo federal. Em linhas gerais, tentou-se comprovar a dependência fi--

Da psicogênese a sociogênese: por uma interação radical no modelo dialético de Jean Piaget

A ideia central "desta tese é que a interação dialética entre o sujeito e o meio, que constitui a base do modelo teórico piagetiano deverá necessariamente ser uma interação radical. Partindo de uma observação do próprio Piaget de que na psicologia e epistemologia genéticas a relação de conhecimento havia sido estudada prioritariamente a partir do sujeito, deixando de ser explorada a partir do objeto, esta tese procura desenvolver as possibilidades abertas por esta exploração, quando se considera a expressão "meio" em sua concepção mais abrangente, incluindo não apenas objetos f1sicos, mas também e inclusive objetos sociais Discutindo a crítica sociológica feita ao modelo piagetiano que o critica por ter omitido a dimensão social em sua formulação, esta tese defenderá a hipótese de que não teria havido omissão: a dimensão social estaria embutida no próprio conceito de interação. Com base em argumentos antropológicos sobre a descontinuidade do espaço são efetuadas séries de generalizações que afinal, sugerem um enriquecimento da teoria piagetiana entendida a partir do objeto. As proposições desse novo modelo fornecem a base para sua aplicação no encaminhamento de problemas cognitivos sociais e psicossociais: é feita uma discussão critica aprofundada do debate sobre a inteligência da criança brasileira marginaliza da travado entre as equipes da Universidade de são Paulo e da Universidade Federal de Pernambuco; a análise -deste debate permite, por sua vez, trazer a construção cognitiva para um referencial antropológico e político. A tese se encerra indicando a correlação da psicogênese e sociogênese compreendidas a partir do modelo construído com a psicologia comunitária e a análise institucional.

Desenvolvimento e validação de método analítico para quantificação da boldina em peumus boldus mol. (monimiaceae) e avaliação preliminar de sua estabilidade

Peumus boldus Molina (Monimiaceae) é uma árvore comum e abundante no Chile, e suas folhas são amplamente empregadas pela medicina tradicional para o tratamento de uma variedade de afecções do sistema digestivo e hepatobiliar. Seus principais constituintes químicos são alcalóides do tipo aporfínicos, sendo a boldina seu maior e mais característico representante, cujas propriedades antioxidantes são extensivamente relatadas na literatura, servindo desta forma como marcador químico para a espécie. Com o objetivo de contribuir com parâmetros de controle de qualidade, um estudo botânico macro e microscópico das folhas e do pó da espécie foi realizado. Características morfológicas, identificadas pela análise macroscópica, como pilosidade, tipologia dos tricomas, proeminência ao redor da base dos tricomas e aparência do bordo, e características microscópicas como estômatos anomocíticos, folha hipoestomática e ocorrência de cristais de oxalato de cálcio denotam valor taxonômico. Parâmetros farmacopéicos como cinzas totais e perda por dessecação foram determinados, e um método de quantificação da boldina foi desenvolvido e validado utilizando a CLAE. O limite mínimo de boldina observado na análise de 10 amostras adquiridas foi de aproximadamente 0,016%. A fim de avaliarse o comportamento de seus constituintes químicos frente a variações de temperatura e umidade, realizou-se estudo de estabilidade acelerada (40ºC ± 2ºC / 75% ± 5% U.R.). A degradação máxima de boldina foi observada após 90 dias em câmara climática chegando a aproximadamente 52%. A reação de degradação sugerida foi de segunda ordem, e o tempo de vida útil e meia-vida calculados foram de aproximadamente 18 dias e 165 dias, respectivamente. Por fim, realizou-se a quantificação de alguns metais pesados nas folhas da espécie, que decresceram na ordem de Fe> Mn> Cu> Ni, sendo que Pb, Cr e Co tiveram níveis abaixo do limite de detecção de 5 μg/g.

Política de assistência social no Brasil: uma análise a partir das tipologias de políticas públicas

The study of public policy typologies is still a knowledge field which lacks more embracing and applicable studies to different sectors. On that perspective, this work, Social Assistance Policy in Brazil: an analysis from the typologies on public policy, pursues to add the relevant literature to social assistance what focus on the public policy ratings. Moreover, it concerns about a study on the the national policy of social assistance implemented by the Brazilian government from the theoretical referrence of the public policy typologies. For that reason, the referential framework of the public policies as well as the analisys of its fundamentals/principles that are indispensable for achieving a bigger goal, that is to tipify the social assistance policy based on the different public policy typologies and characterize it through the main elements which are intrinsec to the social political and economic reality of Brazil. Thus, the issue suggested for the work is: what is the profile and the political trajectory of the social assistance implemented by the Brazilian Government? How it presents, above all, the features of a distributive, focused and lawful policy, the work has been done througho the following hypothesis: the social assistance policy in Brazil has been of universal, assistance, and focusing aspects. For each of those features granted to the social assistance policy, there is a gathering of changes according to the social, political and economic moment of the country and that stands out due to the different institutions within every cyclical period. The work showed that besides the social policy has gone through meaningful changes during the last decades, even though the adoption of the Organic Law of Social Assistance and its rules, some of the mentioned characteristics still remain, as long as the State s primacy goes on being the economic policies over the dubbed social policies. Notwithstanding, the social assistance will build up itself from the materialization of the growing of the social rights related to the State, but also assuming an important role on the amplified reproducing process regarding the capitalist social relations

Educação em saúde em hanseníase: estratégia na educação básica, Parnamirim/RN

Leprosy is an ancient disease that still stands as a public health problem worldwide, especially in the considered developing countries. Of these, Brazil still has large areas of endemicity. The disease remains high among those younger than 15 years old. In this group, the national index achieves 0.6 every 10 000 inhabitants and reaches 2 in the North and Midwest of Brazil. Therefore, the plan of the Ministry of Health is to prioritize the fight against disease in critical areas, providing early diagnosis and timely treatment, especially for patients under 15 years old. This research aimed to: identify the knowledge of students from three schools of basic education in Parnamirim/RN about the risk of getting ill in leprosy; conduct them health education on this topic. An exploratory-descriptive study with quantitative and qualitative nature. Data collection consists of two steps: questionnaire and health education on leprosy. The study was approved by the Research Ethics Committee (REC) of UFRN through the opinion nº 204/2009. Quantitative data obtained were organized, categorized, typed and submitted to the Microsoft Office - Excel for quantitative analysis with simple percentage. Qualitative data were subjected to a content analysis according to Bardin. The sample consisted of 164 students of basic education, most of which is: 1st year of high school, from 11 to 15 years, in the afternoon shift, female gender, skin color white and residents in the municipality of Parnamirim/RN. Still, each student living with four people curiously did not respond in relation to occupation of the father. But the same answered their mother as a housewife and a family income of one to less than four minimum wages. There have been significant results compared the performance of health education in leprosy. Initially, students possessed little knowledge about leprosy. Subsequent to health education, most knew the answer about the disease, transmission, cause, where to get help in case of suspicion of leprosy and the need for the people who lives with leprosy patients to also seek for help, the understanding about if it is treatable or not. Content analysis has established the following themes: axis I, what I do not know about leprosy: cure, fear and prejudice. Axis II, what I know about leprosy, we identified: cure, effectiveness of health education and social exclusion in the past. It is considered the scope of the proposed objectives by matching the effectiveness of health education on leprosy in basic education in Parnamirim/RN; emphasizes, therefore, the importance of understanding the knowledge of public school students. It is expected of them to detect early cases of leprosy in their communities; encourage adherence to treatment as quickly as possible; prevent disability; reduce the stigma surrounding the disease.

Aprendendo e ensinando o sistema de numeração decimal: uma contribuição à prática pedagógica do professor

The central question of the present study is to identify the epistemological knowledge that the teachers-trainees possess regarding the characteristics (properties) of the decimal numbering system; its purpose is to offer a contribution to the pedagogic practice of the teachers who work within the Basic Literacy Cycle, in terms of what concerns both the acquisition of contents and the development of the knowledge that helps them in the elaboration of adequate strategies to working with the Decimal Numbering System in the classroom. The study is based on the constructivist sociointeractionist approach to teaching Mathematics and it constitutes, in itself, a methodological intervention with the teachers-trainees engaged in the Professional Qualification Program in Basic Education of the Federal University of Rio Grande do Norte. The foundations of the study were found in investigations of researchers who had carried out studies on the construction of numerical writing, showing, for instance, that the construction process of ideas and procedures involved in groupings and changes to base 10 take a lot longer to be accomplished than one can imagine. A set of activities was then elaborated which could not only contribute to the acquisition of contents but that could also make the teachers-trainees reflect upon their teaching practices in the classroom so that in this way they will be able to elaborate more consistent didactic approaches, taking into consideration the previous knowledge of the students and also some obstacles that often appear along the way. Even when teachers have access to the most appropriate dicactic resources, the lack of knowledge of the content and of the real meaning of that content make the Decimal Numbering System, a subject of fundamental importance, be taught most times in a mechanical way. The analisys of the discussions and behaviours of the teachers-trainees during the activities reavealed that they made them reflect upon their current practices in the classroom and that, as a whole, the aims of each of the activities carried out with the teachers-trainers were reached

The deep mycoses in HIV infection

The deep mycoses are uncommon infections, usually acquired from the inhalation or ingestion of fungal spores, sometimes from the soil in areas of endemicity, such as in the Americas and south-east Asia, or from decaying vegetable matter. They are also seen in immunocompromised persons and, increasingly, in HIV-infected persons. Respiratory involvement is frequent, with granuloma formation, and mucocutaneous involvement may be seen. Oral lesions of the deep mycoses are typically chronic but non-specific, though nodular or ulcerative appearances are common. Person-to-person transmission is rare. In HIV disease, the most common orofacial involvement of deep mycoses has been in histoplasmosis, cryptococcosis, aspergillosis and zygomycosis. Diagnosis is usually confirmed by lesional biopsy although culture may also be valuable. Treatment is with amphotericin or an azole.

Efeito da adição de probiótico e/ou prebiótico em dietas de leitões desmamados sobre o desempenho, incidência de diarréia e contagem de coliformes totais

In the Experiment 1, 50 pigs weaned at the 21 days were fed with either of five diets: T1 - basal diet; T2 - basal diet + antibiotic; T3 - basal diet + probiotic; T4 - basal diet + prebiotic; T5 - basal diet + simbiotic. The variables studied were body weight, feed intake and feed conversion in the Phase 1 (21 to 43 days), Phase 2 (44 to 57 days), Phase 3 (58 to 70 days) and Total Phase (21 to 70 days). During the performance experiment, a fecal survey score was conducted to verify diarrhea incidence. In the Experiment 2, 44 pigs weaned at 21 days were fed with the same diets of Experiment 1. Pigs were slaughtered at three differents ages (at weaning, at seven and 14 days after weaning). A segment of the small intestine was collected for analisys of total coliformes. The results showed that the best performance was obtained with the utilization of prebiotic and simbiotic. There were not differences in relation to diarrhea incidence among the treatments studied. The addition of probiotic and/or prebiotic in the diet prevented increase of colonization by pathogenic bacterias from seven to 14 days after weaning.

Atividade antioxidante e antimicrobiana do alecrim (Rosmarinus officinalis L.) em filés de tilápia (Oreochromis ssp) salgados secos durante o armazenamento congelado

Rosemary (Rosmarinus officinalis L.) is a spice from Lamiaceae family known since ancient times because its medicinal effects and, currently, several studies have pointed its antioxidant and antimicrobian effects. Lipid oxidation is a problem in food production because proceed the lost of organoleptical and nutritional qualities so required in Market. Fish salting is an ancient conservation method that expect reduce water activity and, consequently, microorganism growth in food, except halophillic bacteria. In the meantime, the inconvenient of this procedure is that the salt accelerates tissue's lipid oxidation. The aim of this work was evaluate the antioxidative and antimicrobian effects by treatment and pre treatment with rosemary (Rosmarinus officinalis L.) aqueous extract in dry salted tilapia fillets, storaged in freezing temperatures. To follow the oxidative, dry salted tilapia fillets were treated or pre treated with rosemary natural extract and storage at -18°C for 240 days. Analisys of 2-thiobarbituric acid reactive substances (TBARS), soluble nitrogen in trichloroacetic acid (TCA), water activity and microbiology were done. The pre treatment (3.39±0,53) and the treatment with rosemary (3.31±0.79) had oxidative index twice lower than the control treatment (6.14±1.21) in the last time of the research. The microbiological rosemary analisys showed count levels of resistant microorganisms to salt (2.0×103CFU/g of sample), whom causes the initial fillets contamination. The microbiological counts remained invariable in all groups during storage periods.
