Full Text Available Na literatura científica de maneira geral as pesquisas sobre a branquitude têm se restringido em investigar a branquitude crítica, deixando de lado a branquitude acrítica. A branquitude crítica refere-se ao indivíduo ou grupo branco que desaprovam publicamente o racismo. Enquanto que a branquitude acrítica refere-se a branquitude individual ou coletiva que sustenta o argumento em prol da superioridade racial branca. Este artigo possui a preocupação em salientar a importância de distinguirmos a branquitude crítica e a branquitude acrítica. O que pode parecer apenas uma simples distinção pode nos levar a analisar com maior atenção e profundidade o crescimento e fortalecimento de grupos neonazistas e membros da Ku Klux Klan: grupos que representam dois significativos exemplos da expressão da branquitude acrítica.

Echinococcus granulosus (sensu lato) (s.l.) and Echinococcus vogeli are causative agents of chronic zoonotic diseases such as cystic and polycystic echinococcosis, respectively. In Brazil, polycystic echinococcosis has a restricted geographical distribution in the North Region, while cystic echinococcosis is observed in the South Region. Domestic dogs (Canis familiaris) fed with raw viscera represent a risk factor for E. granulosus (s.l.) infection in the South Region. Although this practice is frequent, it remains unclear whether domestic dogs are infected with E. vogeli in the state of Acre, located in the Amazon basin in the North Region of Brazil. The aim of this study was to investigate this gap in the polycystic echinococcosis epidemiology. Sixty-five fecal samples were collected from the ground in five municipalities (Sena Madureira, n = 14; Rio Branco, n = 06; Bujari, n = 06; Xapuri, n = 30; and Epitaciolândia, n = 09) located in the state of Acre, northern Brazil. The samples were screened for parasites by copro-PCR using the cox1 gene associated with automated sequencing. Echinococcus vogeli was molecularly confirmed in a sample from Sena Madureira and E. granulosus (sensu stricto) (s.s.) (G1) in a sample from Rio Branco. These findings indicate that molecular assays are useful in typing Echinococcus taxa from fecal samples of dogs in northern Brazil. The present study is the first molecular record of E. vogeli in domestic dogs found in the state of Acre, reinforcing their role as a source of infection for humans. Because E. granulosus (s.s.) (G1) was detected for the first time in the North Region, from the epidemiological standpoint this finding is highly relevant, because it expands the known geographical distribution, which was previously restricted to the South Region of Brazil.

Full Text Available Abstract Although sheep farming has grown in the state of Acre over the past four decades, little is known about occurrences of helminthiases in the herds of this region. The objective of the study was to assess the occurrences of non-intestinal helminthiasis among sheep slaughtered in Rio Branco. A total of 110 sheep livers were inspected from two slaughter batches (july 2014 and march 2015 in a slaughterhouse in Rio Branco. Livers with macroscopic lesions were photographed and were then subjected to histopathological analysis under an optical microscope. The macroscopic lesions showed small nodes with inflammatory characteristics and areas of fibrosis, which appeared to be calcified, thus suggesting a granulomatous reaction. Of the 110 evaluated livers, we noticed 110 nodules in total; these nodules have an average size of 0.5 cm. The histopathological analysis showed alterations to the architecture of the hepatic lobe, with multiple foci of necrosis and polymorphonuclear cells. Two samples revealed the presence of helminths from Nematode class and Capillaria sp. eggs identified by the typical morphology and morphometry. This seems to be the first report of Capillaria sp. in sheep livers in Brazil, and it serves as an important alert regarding animal health surveillance and control and regarding the Capillaria sp. zoonotic role in humans.

Objective: To identify, among the municipalities of the state of Acre, Brazil, those with the highest incidence of leptospirosis between 2010 and 2015, and in addition, to determine the prevalence of this disease between the sexes. Methods: Descriptive study, of documentary character, with epidemiological base and quantitative approach. It was made by available documents through the Department of Informatics of the Unified Health System of Brazil (DATASUS and also by the Health Secretary of State of Acre (SESACRE. Variables were selected as sex, age and year of notification. Regarding the analysis, it is emphasized that it was quantitative and descriptive and the results were presented in tables built in Microsoft Word. Results: It was found that the capital of the state of Acre, Rio Branco, led every year, contributing to the higher proportion of notifications related to leptospirosis. Regarding gender, there was a predilection for males and among age groups, the period of 20 to 39 years contributes to the greater number of cases of the disease. Conclusion: Leptospirosis is a worldwide public health problem and in the state of Acre, the high rainfall, the agglomeration of low income combined with inadequate sanitation, collaborate to infestation of transmitters animals, providing high rates of the disease. Thus, it appears that these high numbers can probably be attributed to the ineffectiveness of preventive activities, as well as insufficient investment directed to social policies and infrastructure sectors. Keywords: Infectious Disease. Leptospirosis. Prevalence. Incidence.

Full Text Available Since 2005, the State of Acre, western Amazon, Brazil, has reported the highest annual parasite incidence (API of malaria among the Brazilian states. This study examines malaria incidence in Acre using spatial and spatio-temporal analysis based on an ecological time series study analyzing malaria cases and deaths for the time period 1992- 2014 and using secondary data. API indexes were calculated by age, sex, parasite species, ratio of Plasmodium vivax to P. falciparum malaria, malaria mortality rate and case fatality rate. SaTScan was used to detect spatial and spatio-temporal clusters of malaria cases and data were represented in the form of choropleth maps. A high-risk cluster of malaria was detected in Vale do Juruá and three low-risk clusters in Vale do Acre for both parasite species. Those younger than 19 years of age and females showed a high incidence of malaria in Vale do Juruá, but working-age males were the most affected in Vale do Acre. The malaria mortality rate showed a decreasing trend across the state, while the case fatality rate increased only in the micro-region of Rio Branco during the study period. We conclude that malaria is a focal disease in Acre showing different spatial and spatio-temporal patterns of cases and deaths that vary by age, sex, and parasite species. Malaria incidence is thought to be influenced by factors related to regional characteristics; therefore, appropriate disease and vector control strategies must be implemented at each locality.

Bats are ancient hosts of Trypanosoma species and their flying ability, longevity and adaptability to distinct environments indicate that they are efficient dispersers of parasites. Bats from Acre state (Amazon Biome) were collected in four expeditions conducted in an urban forest (Parque Zoobotânico) and one relatively more preserved area (Seringal Cahoeira) in Rio Branco and Xapuri municipalities. Trypanosoma sp. infection was detected by hemoculture and fresh blood examination. Isolated parasite species were identified by the similarity of the obtained DNA sequence from 18S rDNA polymerase chain reaction and reference strains. Overall, 367 bats from 23 genera and 32 species were examined. Chiropterofauna composition was specific to each municipality, although Artibeus sp. and Carollia sp. prevailed throughout. Trypanosoma sp. infection was detected in 85 bats (23·2%). The most widely distributed and prevalent genotypes were (in order) Trypanosoma cruzi TcI, T. cruzi marinkellei, Trypanosoma dionisii, T. cruzi TcIV and Trypanosoma rangeli. At least one still-undescribed Trypanosoma species was also detected in this study. The detection of T. cruzi TcI and TcIV (the ones associated with Chagas disease in Amazon biome) demonstrates the putative importance of these mammal hosts in the epidemiology of the disease in the Acre State.

Abstract. The occurrence of Gargaphia lunulata (Mayr (Hemiptera: Tingidae was observed in leaves of four host plants: rue (Ruta graveolens L. and jack bean (Canavalia ensiformis (L. DC in an urban residential garden, in the municipality of Rio Branco, Acre State, Brazil and Crotalaria spectabilis (L., jack bean and okra (Abelmoschus esculentus L. Moench in a greenhouse, in the municipality of Londrina, Paraná State, Brazil. The colonies were found exclusively on the abaxial face of the leaves, causing chlorosis, wilting and early senescence of the same. Because G. lunulata is considered to be an important passion fruit pest in Brazil, the planting of the mentioned plant species, in intercropping or near to passion fruit crops, would not be recommended, since they could serve as plant species inoculum to passion fruit cultivation. Therefore, the occurrence of G. lunulata associated to R. graveolens and jack bean in Acre State; and C. spectabilis, jack bean, and okra, in Paraná State is record for the first time. In addition, the present work reports the first occurrence of this tingid to the States of Acre and Paraná and reports two new hosts for this insect, R. graveolens and C. spectabillis in Brazil.

Full Text Available The colonization process and successional patterns of a periphytic algal community were evaluated in a Amazonian Viveiro Lake (Rio Branco, Acre, Brazil. Sampling was performed over a period of 35 days; at four-day intervals for 20 days, and then at five-day intervals. Water sampling for physical, chemical and biological analyses was done during the dry and rainy season. Glass slides were used as artificial substrates for periphyton colonization. The structural community was evaluated through population density, algae class, diversity indices and descriptive species. Species richness, diversity and evenness increased as succession progressed. While density of Bacillariophyceae, Euglenophyceae and Zygnemaphyceae increased with succession, Cyanobacteria remained dominant. Synechocystis aquatilis, Synechocystis diplococcus and Navicula pseudolanceolata were the main descriptive species in both the dry and rainy season. Cymbela tumida, Frustulia rhomboides, Trachelomonas lacustris and Closterium acicularis was correlated with an increase in hydrologic level during the rainy season. Conversely, the density of Chlamydomonas sp., Chroomonas nordstedtii, Trachelomonas volvocinopsis, Trachelomonas volvocina and Synechococcus linearis was correlated with an increase in water transparency during the dry season. In general, the periphytic algal community showed high diversity and species richness independent of season. Season also had little influence on representation of algae class and main descriptive species. However, successional patterns varied by season, and changes in hydrologic levels acted directly on the succession path of periphytic algae. More research on periphyton dynamics is needed to improve our understanding of tropical lake ecosystems, especially in Amazonian.A colonização e o modelo sucessional da comunidade de algas perifíticas foram avaliados no amazônico Lago do Viveiro (Rio Branco, Acre, Brasil.

Phlebotomine sand flies (Diptera: Psychodidae) are insects of medical importance due to their involvement in the zoonotic transmission of Leishmania spp. to vertebrates. The aim of this work was to study the ecology of the sand fly fauna of two types of environments, a rural environment (the Transacreana Road) and an urban park (Horto Florestal Park), both located in the municipality of Rio Branco in the state of Acre, Brazil. Additionally, this study intended to investigate Leishmania infection and blood meal sources of these sand flies using molecular techniques. The sand fly fauna was studied in different environments (i.e. forest and peridomestic environments in a rural area, and an urban forest) using Shannon traps and HP light traps to collect sand fly specimens over 13 consecutive months (December 2014 to January 2016). For investigating natural infection by Leishmania and the source of sand fly blood meals, DNA samples were extracted from female sand flies and subjected to polymerase chain reaction targeting ITS1 and cytb genes. DNA sequencing was subsequently used to identify species of Leishmania and the source of blood meals. A total of 2515 individual sand flies of 43 species were collected and identified, Trichophoromyia auraensis (839; 33.35%), Trichophoromyia spp. (537; 21.35%) and Evandromyia saulensis (187; 7.43%) were more abundant in the rural area (S = 41 species) than in the urban forest. No significant differences were found in species richness between forest and peridomestic environments in the rural area (H = 0.04; P > 0.05), but a larger number of species was found in the forest. Leishmania DNA was sequenced in 13 samples, confirming the presence of L. (V.) braziliensis in Th. auraensis (n = 1), Ev. saulensis (n = 2), Ev. walkeri (n = 1), Ps. llanosmartinsi (n = 1), Pi. nevesi (n = 2), Ps. davisi (n = 1), Ps. ayrozai (n = 1), Pa. aragaoi (n = 1), Ny. antunesi (n = 1) and Ev. infraspinosa (n�

Abstract. The açai palm (Euterpe oleracea Martius is a native palm tree from the Amazon region floodplains and may be indicated as the most economically profitable species of this genus. Its fruit pulp is extracted and widely consumed by the population of northern Brazil in several ways. With the expansion of the planted area many factors may affect the production and limit the cultivation, highlighting the occurrence of insect pests that cause losses in production. This report presents the first occurrence of the leafhopper Aetalion reticulatum (Linnaeus (Hemiptera: Auchenorrhyncha: Aethalionidae in E. oleracea plants. The occurrence of this insect associated with açai palms in Rio Branco, Acre, increases the list of hosts for this leafhopper in Brazil and reinforces the need for studies of population dynamics, survey of natural enemies, levels of damage and control methods in order to anticipate population outbreaks of this pest in commercial plantations of açai palms in the State.

Studies on the sandfly fauna to evaluate natural infection indexes are still limited in the Brazilian Amazon, a region with an increasing incidence of cutaneous leishmaniasis. Here, by using a multiplex polymerase chain reaction directed to Leishmania kDNA and hybridisation, we were able to identify L. (Viannia) subgenus in 12 out of 173 sandflies captured in the municipality of Rio Branco, Acre state, revealing a positivity of 6.94%. By sequencing the Leishmania 234 bp-hsp70 amplified products from positive samples, infection by L. (V.) braziliensis was confirmed in five sandflies: one Evandromyia saulensis, three Trichophoromyia auraensis and one Pressatia sp. The finding of L. (Viannia) DNA in two Ev. saulensis corresponds to the first record of possible infection associated with this sandfly. Moreover, our study reveals for the first time in Brazil, Th. auraensis and Pressatia sp. infected by L. (Viannia) parasites. PMID:28076470

As análises feitas a partir do software Alceste evidenciaram quatro classes discursivas, que compartilham uma forte oposição às cotas raciais, diferenciando-se apenas em relação ao argumento utilizado. A primeira classe enfatiza a inexistência de diferenças intelectuais entre negros e brancos e, na segunda classe, vem a ideia de que as desigualdades sociais entre negros e brancos seriam produto do preconceito contra pobres, assim as cotas deveriam ser sociais. As duas últimas classes compartilham a preocupação com a qualidade do ensino, defendendo que o sistema de cotas poderia baixar o nível intelectual das universidades e que o correto seria investir na melhoria do ensino fundamental e médio.

Full Text Available Foi estudada a distribuição da a. coroídea anterior em 10 hemisférios cerebrais humanos de brancos e negros. Todas as peças foram injetadas a fresco, com massa corada e fixadas em formol. Nelas, a a. coroídea anterior foi dissecada desde a sua origem até a sua incorporação ao plexo coróide do corno inferior do ventrículo lateral. Em seguida à dissecção, as peças foram cortadas em fatias horizontais, de aproximadamente 0,5 cm de espessura. Constatou-se que a a. coroídea anterior se origina da a. carótida interna, e que ela não apresenta diferenças étnicas e sexuais, estatisticamente significantes, no que diz respeito ao seu território de distribuição. Este compreende, segundo nossas observações, as seguintes estruturas: úncus, hipocampo, tracto óptico, plexo coróide do corno inferior do ventrículo lateral e braço posterior da cápsula interna (100%; cauda do núcleo caudado (99% ± 0,99; 3/5 intermédios da porção cranial da base do pedúnculo cerebral, corpo amigdalóide e zona incerta (98% ± 1,40; 1/5 lateral da porção cranial da base do pedúnculo cerebral (92% ± 2,71; porção anterior do corpo geniculado lateral (89% ± 3,13; segmento medial do globo pálido (88% ± 3,25; núcleo subtalâmico (39% ± 4,88; grupamento nuclear lateral do tálamo (26% ± 4,39; segmento lateral do globo pálido (17% ± 3,76; grupamento nuclear posterior do tálamo (13% ± 3,36; porção posterior do putamen (9% ± 2,86; 1/5 medial da porção cranial da base do pedúnculo cerebral (7% ± 2,55 e substância negra (3% ± 1,71.

Full Text Available OBJETIVO: Conhecer as percepções de risco associadas ao uso de agrotóxicos no trabalho rural de pequenos produtores rurais. MÉTODO: Estudo de percepção de riscos relacionados ao trabalho rural, realizado entre o segundo semestre de 2008 e o primeiro de 2009, com base na avaliação psicológica de 42 pequenos agricultores do município de Rio Branco, AC, por meio de questionário estruturado com questões abertas e fechadas e aplicação de escalas psicométricas. RESULTADOS: Entre as mulheres, destacou-se a invisibilidade dos riscos associados ao uso desses agentes químicos no seu cotidiano de trabalho. A maioria das mulheres participantes não percebia a seriedade dos problemas de saúde relacionados à exposição a agrotóxicos, nem identificava como perigosas as atividades de trabalho que desempenhava. Entre os homens, observou-se a construção de estratégias defensivas baseadas na negação dos riscos, tática utilizada por esses indivíduos como forma de permanecerem, dia após dia, inseridos em um processo de trabalho sabidamente injurioso. CONCLUSÃO: O estudo mostrou que a percepção de riscos daquele grupo de pequenos agricultores influencia suas práticas de trabalho e a forma como responde frente ao risco representado pelo uso de agrotóxicos, devendo ser, portanto, objeto de análise em ações de vigilância em saúde do trabalhador e no escopo de iniciativas de gerenciamento de riscos.

Trying to Learn Lessons for Response to Extreme Events: Paradigm Shifts Affecting Civil Defense in the Trinational Region of Southwestern Amazonia

Science.gov (United States)

Santos, G. L. P.

2015-12-01

The last ten years have seen several extreme climate events in southwestern Amazonia with historic impacts. The City of Rio Branco, Capital of Acre, Brazil´s westernmost State, suffered its seventh consecutive annual flooding and its worst in March 2015. The city of Tarauacá, also in Acre, registered 12 flooding events between November 2014 and April 2015. The most recent flood of the trinational Acre River in 2015 set historic records for flood stage and number of displaced persons in Cobija, the Capital of Pando, Bolivia. From February to April 2014, floods of the Madeira River disrupted the one highway between Acre and southern Brazil. Puerto Maldonado, the capital in Madre de Dios Region of Peru had its worst flood in 50 years during 2014. In 2005 and 2010, prolonged droughts combined with ignition sources resulted in tens to hundreds of thousands of hectares of fire-damaged rainforests in the Madre de Dios, Acre and Pando (MAP) Region. The Civil Defenses in these three contiguous political units faced several abrupt paradigm shifts that affected their responses: 1) The drought of 2005 showed dramatically that regional rainforests do burn; 2) The recent flooding history, particularly in 2012 and 2015, demolished the cultural icon of a nine-year recurrence interval; 3) What happens outside your territory can be devastating. The Madeira River flood impeded an estimated 200 million dollars from circulating in Acre; 4) The past can be a terrible guide. For Cobija and Rio Branco, the 2015 flood was on the order of a meter higher than any other. Many home dwellers did not evacuate in time because they used past floods as a guide; 5) A collapse in communication - cell phones, land lines, and Internet - can get worse. In 2012, such a collapse occurred in two border towns for 5 days, yet in 2015 it lasted more than 11 days. Research is needed to address how institutions linked to Civil Defense can shift paradigms in time to be more effective.

Full Text Available Resumo: Na maioria dos países do mundo ocidental, universidades que formam a elite costumam ser redutos da branquidade refratários a grupos socialmente excluídos. No Brasil, com mais da metade da população formada por pretos e pardos, as universidades públicas sempre foram um território quase exclusivamente branco. O Rio Grande do Sul, estado brasileiro com a segunda maior percentagem de população branca do país, reflete esse quadro. Ele enaltece o legado dos grupos imigrantes de origem europeia em contraste com a pequena visibilidade atribuída à contribuição da população negra e indígena. No período 2008 a 2012, a Universidade Federal do Rio Grande do Sul, a mais importante do estado, implementou uma política de ação afirmativa que aumentou as oportunidades de alunos pretos, pardos e indígenas entrarem em seus cursos de graduação. O artigo discute essa política - sua aprovação, características, implantação, avaliação e reformulação, assim como seus resultados. Analisa a experiência de um grupo de universitários negros e indígenas, que foram dos primeiros a ingressar na UFRGS através da reserva de vagas. Ao final, aponta os significados das políticas de inclusão de negros e indígenas nas universidades públicas brasileiras e os desafios que elas representam para essas instituições.

Observou-se que tais agentes comportaram-se de maneira diferente de acôrdo com o vinho a ser clarificado. Para os vinhos brancos testados, verificou-se que a bentonita foi o melhor clarificodor. As observações concordam com resultados obtidos por outros pesquisadores para diferentes vinhos.A laboratory trial was carried out to determine the behavior of different fining agents in samples of white wine obtained from various grape varieties. These tested wines were produced in two regions of the State of São Paulo and one of Minas Gerais. It was observed that these fining agents behaved differently according to the type of wine to be cleared. In our experimental trials bentonita was the best fining agent. These observations agree with those obtoined by others authors in other parts of the world. As a general procedure it is advisable to conduct small-scale fining tests in the laboratory before attempting to clarify the bulk volume of wine in the winery, to determine the efficiency of the fining agent, its effect on the wine, and the quantity necessary to clarify.

Full Text Available Objective: To investigate the positivity of Wuchereria bancrofti (W. bancrofti in immigrants who entered the country through Rio Branco, reducing the risk of introduction of parasites into new areas and endemic areas of the past. Methods: It was realized a descriptive study. The AD12-ICT card test was applied on all immigrants living temporarily in the Chacara Alliance shelter, located in the metropolitan area of Rio Branco-AC, Brazil. For the positive patients, 10 mL of venous blood was collected between 11:00 pm and 1:00 am. About 4 mL of venous blood was collected to detect the presence of microfilariae in circulation in the tube using ethylene diamine tetraacetic acid and 6 mL of venous blood was collected to obtain blood serum for the Og4C3-ELISA, antibody Bm-14 and DNA-W. bancrofti tests. Results: The present study evaluated 415 individuals in September 2014 by circulating filarial antigen for W. bancrofti using the AD12-ICT card test. A total of 15/415 (3.61% positive cases were found, all from Haiti. Night blood collection and serum were performed on 1/14 for confirmation the infection of W. bancrofti, which presented 34 microfilariae/mL, antigen, antibodies and PCR positives. Conclusions: This surveillance action reveals, in a pioneering and unequivocal manner, that Brazil is an influx of immigrants carrying lymphatic filariasis and there is an urgent need to step up surveillance at the main entry point for immigrants. Active surveillance may prevent the reintroduction of lymphatic filariasis in areas under control, or prevent its introduction into other states of Brazil.

Living trees constitute one of the major stocks of carbon in tropical forests. A better understanding of variations in the dynamics and structure of tropical forests is necessary for predicting the potential for these ecosystems to lose or store carbon, and for understanding how they recover from disturbance. Amazonian tropical forests occur over a vast area that encompasses differences in topography, climate, and geologic substrate. We observed large differences in forest structure, biomass, and tree growth rates in permanent plots situated in the eastern (near Santarém, Pará), central (near Manaus, Amazonas) and southwestern (near Rio Branco, Acre) Amazon, which differed in dry season length, as well as other factors. Forests at the two sites experiencing longer dry seasons, near Rio Branco and Santarém, had lower stem frequencies (460 and 466 ha(-1) respectively), less biodiversity (Shannon-Wiener diversity index), and smaller aboveground C stocks (140.6 and 122.1 Mg C ha(-1)) than the Manaus site (626 trees ha(-1), 180.1 Mg C ha(-1)), which had less seasonal variation in rainfall. The forests experiencing longer dry seasons also stored a greater proportion of the total biomass in trees with >50 cm diameter (41-45 vs 30% in Manaus). Rates of annual addition of C to living trees calculated from monthly dendrometer band measurements were 1.9 (Manaus), 2.8 (Santarém), and 2.6 (Rio Branco) Mg C ha(-1) year(-1). At all sites, trees in the 10-30 cm diameter class accounted for the highest proportion of annual growth (38, 55 and 56% in Manaus, Rio Branco and Santarém, respectively). Growth showed marked seasonality, with largest stem diameter increment in the wet season and smallest in the dry season, though this may be confounded by seasonal variation in wood water content. Year-to-year variations in C allocated to stem growth ranged from nearly zero in Rio Branco, to 0.8 Mg C ha(-1) year(-1) in Manaus (40% of annual mean) and 0.9 Mg C ha(-1) year(-1) (33% of

Full Text Available O artigo analisa a situação-problema da exploração comercial de madeira como modo de uso da terra na comunidade Rio Branco da Reserva Extrativista Chico Mendes, estado do Acre, e a polêmica implantação do Projeto de Manejo Florestal Comunitário (PMFC. A partir de entrevistas com extrativistas e profissionais de nove instituições governamentais e nãogovernamentais, foi elaborada uma lista com oito usos da terra para a Reserva. Na etapa seguinte, cada participante foi solicitado a ordenar os usos de acordo com as suas prioridades individuais. Por meio do Indicador de Sustentabilidade em Sistemas de Interesse (ISSI foi calculado o grau de convergência entre o interesse (ordenamento de prioridades de cada extrativista e o interesse da comunidade, e entre os extrativistas e as instituições. O manejo de produtos florestais não-madeireiros (PFNMs e o cultivo da roça ainda são os usos da terra preferidos pelos extrativistas 'não-participantes' do PMFC, que atribuíram prioridade mínima para a exploração da madeira. Os extrativistas que já haviam aderido ao PMFC apontaram a exploração da madeira como sua prioridade máxima. Membros das instituições apontaram preferência pelos usos da terra com menor impacto sobre a floresta, posição mais próxima das prioridades dos extrativistas que ainda não haviam aderido ao PMFC. Numa segunda rodada de ordenamento de prioridades do uso da terra, os extrativistas 'participantes' do PMFC mudaram substancialmente o seu primeiro ordenamento, elegendo o manejo de PFNMs e o cultivo da roça como prioridades máximas. Os resultados revelam que a questão da exploração da madeira na Reserva constitui um complexo sistema de interesses e que muitos extrativistas ainda se sentem inseguros em relação às consequências da implementação do projeto, ou seja, que o projeto não estava suficientemente maduro para ser colocado em prática.

Full Text Available O artigo descreve e analisa alguns aspectos da transformação que ocorre entre os Yanomami na Venezuela como produto da crescente troca com a sociedade nacional, em particular com o sistema médico. Procura-se mostrar como muitos aspectos da vida moderna e contemporânea Yanomami só podem ser compreendidos a partir de conceitos da antropologia amazônica, desenvolvidos em contextos mais tradicionais, conceitos como o de 'afinidade potencial'. Explorando a natureza do espaço sociopolítico contemporâneo, de como a interação entre brancos e Yanomami sustenta tal espaço e tornando explícitas as formas indígenas de ser e viver que se mantêm nessa transformação e troca com os brancos, oferecemos algumas reflexões que podem ser úteis na análise das situações de contato étnico em diferentes partes da Amazônia e com diferentes agentes dos estados nacionais.This article describes and analyses various aspects of the transformation occurring among the Yanomami in Venezuela, a product of their increasing exchanges with national society and in particular the medical system. The article looks to show how many aspects of Yanomami contemporary and modern life can only be understood by employing concepts from Amazonian anthropology, such as 'potential affinity,' developed in more traditional contexts. By exploring the nature of contemporary sociopolitical space and how the interaction between Whites and Yanomami sustains this space, making explicit the very indigenous ways of being and living that persist through transformation and exchange with Whites, the article tackles issues which may be useful in the analysis of ethnic contact situations in other parts of Amazonia and involving different national state agents.

Full Text Available São apresentados os resultados organolépticos e analíticos de 15 amostras de vinhos de mesa brancos e 15 de tintos, adquiridos no comércio de Campinas, em 1960. Foram encontradas poucas amostras com características inteiramente satisfatórias, notando-se, principalmente, deficiências de clarificação e de filtração. Das 15 marcas de vinhos brancos, só três se apresentaram perfeitamente brilhantes, e sete, ligeira ou completamente turvos. Nos tintos, em geral, foi maior a turbidez. Verificou-se, também, a presença, entre os brancos, de vinhos com acidez volátil acima do limite permitido pela legislação brasileira. Foi notada a ausência de anidrido sulfuroso total e livre. Os resultados dos outros componentes mostraram-se, todavia, bastante satisfatórios. Foram ainda observados o comprimento insuficiente das rôlhas para garantir a boa conservação do vinho, e a desuniformidade das garrafas quanto a tipo, forma, capacidade e côr.Fifteen hrands of white and 15 of red wines were collected from groceries for analysis and flavor tests. Very few samples were satisfactory. Most of the wines had been poorly clarified and filtered. Only three of the 15 samples of white wines were brilliant; seven were classified as slightly cloudy or cloudy. Cloudiness was higher among the red wines. Two samples of the white wines had a high volatile acidity, above the limit permitted by the Brazilian regulation. Lack af free and total sulfur dioxide was observed. As far as the other wines constituents are concerned, all analysed samples were satisfactory. The corks utilized were generally shorter than it is desirable to seal the bottles satisfactorily. Also, the bottles were not uniform in type, shape, capacity, and color.

Full Text Available A valoração ambiental é uma ferramenta relevante para determinação do valor de bens que não possuem mercado definido. O parque ambiental "Chico Mendes", situado em Rio Branco - Acre, em razão de suas características de não-rivalidade e não-excludência, é um bem público. O método de valoração contingente constitui uma das técnicas que possibilitam a determinação do valor econômico de um bem público. De forma geral, este trabalho busca determinar o valor econômico total do parque "Chico Mendes". Os resultados mostram que a renda familiar, o valor da verdadeira disposição a pagar, o sexo e a idade são variáveis importantes para explicar probabilidade do indivíduo se dispor a contribuir para conservação e manutenção dos serviços oferecidos pelo parque. Por fim, o bootstrapping e a análise de risco fornecem maior segurança aos resultados encontrados.The object of this study is the environmental park "Chico Mendes" located in Rio Branco - Acre. Being unique and all-enclosing in its nature it is a public asset. The contingent valuation makes possible the determination of the total economic value total of a public asset. The people's willingness to pay for the park maintenance and conservation shows a determination of the consumers' preference. This work attempts to determine the total economic value of the park. The results show that family income, value of monthly contribution, sex and age explain the probability of a person to contribute to the park conservation. Finally, bootstrapping and risk analysis provide greater safety to the results found.

Alchemy, Prophecy, and Politics in Eighteenth-Century Iberia: Anselmo Castelo Branco's Critique of Benito Feijoo.

Science.gov (United States)

Leitão, José Vieira

2016-11-01

The Benedictine monk Benito Jerónimo Feijoo (1676-1764) is now considered one of the major figures of the Spanish and Iberian Enlightenment. However his work, both in Spain and in Portugal, was far from being universally acclaimed. His critical approach to the subject of alchemy in his essay "Piedra Filosofal," published in the third volume of his magisterial Teatro Crítico Universal (1726-1739), sparked an unexpected response from the Portuguese alchemist Anselmo Castelo Branco, who sought to refute Feijoo's claims in his own work, the Ennoea. This paper presents an outline of this exchange and its position within Iberian Enlightenment circles. It further argues that Castelo Branco's defence of alchemy was informed by his political and prophetic views, in particular his adherence to the Portuguese messianic doctrine of Sebastianism.

Full Text Available Several entities must be considered when a patient presents with a white dot syndrome. In most cases these can be distinguished from one another based on the appearance or distribution of the lesions, the clinical course, or patient variables such as age, sex, laterality, and functional and image examinations. In this paper we review the distinctive and shared features of the white dot syndromes, highlighting the clinical findings, diagnostic test results, proposed etiologies, treatment, and prognosis.Várias doenças devem ser consideradas quando nos deparamos com paciente com uma entidade clínica incluída no grupo das "síndromes dos pontos brancos retinianos". O diagnóstico diferencial na maioria das vezes é baseado na aparência e/ou na distribuição das lesões, no curso clínico, ou por algumas variáveis relacionadas ao paciente, tais como idade, sexo, lateralidade, bem como por meio de exames funcionais e de imagem. O presente artigo revisa os achados clínicos das doenças que fazem parte do grupo das "síndromes dos pontos brancos retinianos", enfatizando as similaridades e as diferenças entre essas entidades. Os exames complementares, bem como a etiologia, o tratamento e o prognóstico de cada uma delas são descritos e comentados.

AECL's advanced CANDU reactor - the ACR

International Nuclear Information System (INIS)

Alizadeh, Ala; Allsop, Peter; Hedges, Ken; Hopwood, Jerry; Yu, Stephen

2003-01-01

The ACR, the next generation CANDU design, represents the next step in development of the CANDU family of designs. AECL has achieved significant incremental improvements to the mid-size CANDU 6 nuclear power plant through successive projects, both in design and in project delivery. Building on this knowledge base, AECL is continuing to adapt the CANDU design to develop the ACR. This paper summarizes the ACR design features, which include major improvements in economics, inherent safety characteristics, performance and construction methods. Aimed at producing electrical power at a capital cost significantly less than that of the current reactor designs, the ACR is an evolutionary design based on the very successful CANDU 6 reactor. The new ACR product is specifically designed to produce power at a cost competitive with other forms of power generation while achieving short construction times, improved safety, international licensability, high investor returns, and low investor risk. It achieves these targets by taking advantage of the latest advances in both pressure-tube and pressure-vessel reactor technologies and experience. The flexibility and development potential of the fuel channel approach also enables designs to be developed that address priorities identified in international long-term specification programs such as the US Department of Energy (DOE) sponsored Generation IV program and IAEA hosted INPRO program. ACR-700 can be built in 36 months with a 48 month project duration, and deliver a lifetime capacity factor in excess of 90%. Overall, the ACR design represents a balance of proven design basis and innovations to give step improvements in safety, reliability and economics. The ACR development program, now well into the detail design stage, includes parallel formal licensing in the USA and Canada. Based on the status of the ACR design and AECL's on-going experience delivering reactor projects on-time and on-budget, the first ACR could be in service by

This paper proposes and analyses the autoregressive conditional root (ACR) time-series model. This multivariate dynamic mixture autoregression allows for non-stationary epochs. It proves to be an appealing alternative to existing nonlinear models, e.g. the threshold autoregressive or Markov...... switching class of models, which are commonly used to describe nonlinear dynamics as implied by arbitrage in presence of transaction costs. Simple conditions on the parameters of the ACR process and its innovations are shown to imply geometric ergodicity, stationarity and existence of moments. Furthermore...

ACR-1000: Operator - based development

International Nuclear Information System (INIS)

Shalaby, B.; Alizadeh, A.

2007-01-01

Atomic Energy of Canada Limited (AECL) has adapted the successful features of CANDU * reactors to establish Generation III + Advanced CANDU Reactor T M (ACR T M) technology. The ACR-1000 T M nuclear power plant is an evolutionary product, starting with the strong base of CANDU reactor technology, coupled with thoroughly-demonstrated innovative features to enhance economics, safety, operability and maintainability. The ACR-1000 benefits from AECL's continuous-improvement approach to design, that enabled the traditional CANDU 6 product to compile an exceptional track record of on-time, on budget product delivery, and also reliable, high capacity-factor operation. The ACR-1000 engineering program has completed the basic plant design and has entered detailed pre-project engineering and formal safety analysis to prepare the preliminary (non-project-specific) safety case. The engineering program is strongly operator-based, and encompasses much more than traditional pre-project design elements. A team of utility-experienced operations and maintenance experts is embedded in the engineering team, to ensure that all design decisions, at the system and the component level, are taken with the owner-operator interest in mind. The design program emphasizes formal review of operating feedback, along with extensive operator participation in program management and execution. Design attention is paid to layout and access of equipment, to component and material selection, and to ensuring maximum ability for on-line maintenance. This enables the ACR-1000 to offer a three-year interval between scheduled maintenance outages, with a standard 21-day outage duration. SMART CANDU T M technology allows on-line monitoring and diagnostics to further enhance plant operation. Modules of the Advanced CANDU SMART technologies are already being back-fitted to current CANDU plants. As well as reviewing the ACR-1000 design features and their supporting background, the paper describes the status of

Os mecanismos envolvidos na suscetibilidade/resistência do hospedeiro frente ao agente não estão ainda elucidados, dentre eles encontra-se a constituição genética. Portanto, o objetivo deste trabalho é avaliar a distribuição dos grupos sangüíneos ABO e Lewis de pacientes com doença de Jorge Lobo em relação à população geral. Foram analisados 13 pacientes provenientes do estado do Acre, 60 indivíduos da região de Bauru (SP não acometidos pela doença em estudo (grupo controle Lewis e 2.673 doadores do Banco de Sangue da cidade de Rio Branco (AC como grupo controle ABO. As presenças dos antígenos eritrocitários foram determinadas pela reação de aglutinação em tubo através dos soros anti-AB, anti-A e anti-B para o fenótipo ABO e dos soros anti-Lewis a e Lewis b para fenotipagem Lewis. As freqüências fenotípicas Lewis e ABO nos pacientes e nos controles são, respectivamente: Le (a- b+ = 54,0% X 72,0%, Le (a+ b- = 15,0% X 6,0%, Le (a- b- = 31,0% X 22,0% ; A =15,4% X 33,6%, B = 30,8% X 10,8%, O = 53,8% X 52,9%, AB = 0 X 2,7%. Embora não tenhamos encontrado resultados estatisticamente significantes, nossos achados sugerem existir suscetibilidade à doença de Jorge Lobo em indivíduos com fenótipo B e com menor freqüência fenotípica Lewis b, conferindo assim um grau de importância epidemiológica como grupo de risco naquele meio ambiente.Jorge Lobo's disease is a mycosis with chronic evolution caused by the fungus Lacazia loboi.

A goal of an imaging accreditation program is to ensure adequate image quality, verify appropriate staff qualifications, and to assure patient and personnel safety. Currently, more than 35,000 facilities in 10 modalities have been accredited by the American College of Radiology (ACR), making the ACR program one of the most prolific accreditation options in the U.S. In addition, ACR is one of the accepted accreditations required by some state laws, CMS/MIPPA insurance and others. Familiarity with the ACR accreditation process is therefore essential to clinical diagnostic medical physicists. Maintaining sufficient knowledge of the ACR program must include keeping up-to-date as the various modality requirements are refined to better serve the goals of the program and to accommodate newer technologies and practices. This session consists of presentations from authorities in four ACR accreditation modality programs, including magnetic resonance imaging, computed tomography, nuclear medicine, and mammography. Each speaker will discuss the general components of the modality program and address any recent changes to the requirements. Learning Objectives: To understand the requirements of the ACR MR Accreditation program. The discussion will include accreditation of whole-body general purpose magnets, dedicated extremity systems well as breast MRI accreditation.

Currently, more than 35,000 facilities in 10 modalities have been accredited by the American College of Radiology (ACR), making the ACR program one of the most prolific accreditation options in the U.S. In addition, ACR is one of the accepted accreditations required by some state laws, CMS/MIPPA insurance and others. Familiarity with the ACR accreditation process is therefore essential to clinical diagnostic medical physicists. Maintaining sufficient knowledge of the ACR program must include keeping up-to-date as the various modality requirements are refined to better serve the goals of the program and to accommodate newer technologies and practices. This session consists of presentations from authorities in four ACR accreditation modality programs, including magnetic resonance imaging, computed tomography, nuclear medicine, and mammography. Each speaker will discuss the general components of the modality program and address any recent changes to the requirements. Learning Objectives: To understand the requirements of the ACR MR Accreditation program. The discussion will include accreditation of whole-body general purpose magnets, dedicated extremity systems well as breast MRI accreditation. Anticipated updates to the ACR MRI Quality Control Manual will also be reviewed. To understand the requirements of the ACR CT accreditation program, including updates to the QC manual as well as updates through the FAQ process. To understand the requirements of the ACR nuclear medicine accreditation program, and the role of the physicist in annual equipment surveys and the set up and supervision of the routine QC program.

Atomic Energy of Canada Limited (AECL) developed the Advanced CANDU Reactor-700 (ACR-700) as an evolutionary advancement of the current CANDU 6 reactor. As a further advancement of the ACR design, AECL is currently developing the ACR-1000 for the Canadian and international market. The ACR-1000 is aimed at producing electrical power for a capital cost and a unit-energy cost significantly less than that of the current generation of operating nuclear plants, while achieving enhanced safety features, shorter construction schedule, high plant capacity factor, improved operations and maintenance, and increased operating life. The reference ACR-1000 plant design is based on an integrated two-unit plant, using enriched fuel and light-water coolant, with each unit having a nominal gross output of about 1200 MWe. The ACR-1000 design meets Canadian regulatory requirements and follows established international practice with respect to severe accident prevention and mitigation. This paper presents the ACR-1000 features that are designed to mitigate limited core damage and severe core damage states, including core retention within vessel, core damage termination, and containment integrity maintenance. While maintaining existing structures of CANDU reactors that provide inherent prevention and retention of core debris, the ACR-1000 design includes additional features for prevention and mitigation of severe accidents. Core retention within vessel in CANDU-type reactors includes both retention within fuel channels, and retention within the calandria vessel. The ACR-1000 calandria vessel design permits for passive rejection of decay heat from the moderator to the shield water. Also, the calandria vessel is designed for debris retention by minimizing penetrations at the bottom periphery and by accommodating thermal and weight loads of the core debris. The ACR-1000 containment is required to withstand external events such as earthquakes, tornados, floods and aircraft crashes

Core retention within vessel in CANDU-type reactors includes both retention within fuel channels, and retention within the calandria vessel. The moderator heavy water in the ACR-1000 calandria vessel, as in any other CANDU-type reactor, provides ample heat removal capacity in severe accidents. The ACR-1000 calandria vessel design permits for passive rejection of decay heat from the moderator to the shield water. Also, the calandria vessel will be designed for debris retention. Core damage termination is achieved by flooding of the core components with water and keeping them flooded thereafter. Successful termination can be achieved in the fuel channels, calandria vessel or calandria vault by water supply by the Long Term Cooling (LTC) pumps and by gravity feed from the Reserve Water System. The ACR-1000 containment is required to withstand external events such as earthquakes, tornados, floods and aircraft crashes. Containment

The ACR (Advanced CANDU Reactor), developed by Atomic Energy of Canada Ltd. (AECL), is designed with constructability considerations as a major requirement during all project phases from the concept design stage to the detail design stage. For ACR-700, a project schedule of 48 months has been developed for the nth replicated unit with a 36 month construction period duration from First Concrete to Fuel Load. AECL, recognizing the immense benefit of collective experience, is partnering with Hitachi Ltd in the development of the ACR power plant design. AECL has gained valuable experience in implementing new construction methods at the Qinshan (Phase III) twin unit CANDU 6 plant in China, and Hitachi likewise has enjoyed success in modular construction of ABWRs in Japan. Utilizing these experiences, AECL is developing the ACR nuclear steam plant (NSP) and Hitachi is developing the Turbine Building. An overall construction strategy, which builds on the success of these construction methods from the nuclear power plant developments in China and Japan, has been developed for the ACR. The overall construction strategy comprises the 'Open Top' construction technique using a Very Heavy Lift crane, parallel construction activities, with extensive modularization and prefabrication. Modules and prefabrications are major features of the ACR design, resulting in an excess of 80% of Reactor Building internal work being completed as modules or as very streamlined traditional construction. This paper reviews the ACR construction strategy and provides examples of modules and how they impact on the ACR construction schedule. In conclusion, the ACR-700 is designed using the latest, proven construction methods to achieve a 36 month construction period for the nth replicated unit. (author)

2011-01-01

Atomic Energy of Canada Limited (AECL) has developed the Advanced CANDU Reactor TM 1 1000 (ACR-1000 TM ) as an evolutionary advancement of the current CANDU 6 reactor. The ACR-1000 design has evolved from AECL's in-depth knowledge of CANDU TM systems, components, and materials, as well as the experience and feedback received from owners and operators of CANDU plants. The ACR design retains the proven strengths and features of CANDU reactors, while incorporating innovations and state-of-the-art technology. It also features major improvements in economics, inherent safety characteristics, and performance, while retaining the proven benefits of the CANDU family of nuclear power plants. To ensure that the ACR design is compliant with Canadian and international requirements, regulatory pre-project reviews of the ACR-1000 (and ACR-700 TM 1 with lower output) were conducted early in the design work. The regulatory feedback from these pre-project regulatory reviews helped AECL to better understand regulatory expectations in Canada, US and the UK, and to make further advancements and improvements in the ACR design to meet the Canadian and international regulatory requirements. This paper provides an overview of the key design features of the ACR-1000 reactor design, and summary of the pre-project reviews by those above-mentioned regulatory bodies, demonstrating opportunities and challenges in licensing process of and pointing to the importance of efficient vendor-regulator interaction.

Through their worldwide operating records, CANDU Nuclear Power Plants (NPPs) have repeatedly demonstrated safe, reliable and competitive performance. Currently, there are fourteen CANDU 6 single unit reactors operating or under construction worldwide. Atomic Energy of Canada Limited's (AECL) Advanced CANDU Reactor - the ACR. - is the genesis of a new generation of technologically advanced reactors founded on the CANDU reactor concept. The ACR is the next step in the evolution of the CANDU product line. The ACR products (ACR-700 and ACR-1000) are based on CANDU 6 (700 MWe class) and CANDU 9 (900 MWe class) reactors, therefore continuing AECL's successful approach of offering CANDU plants that appeal to a broad segment of the power generation market. The ACR products are based on the proven CANDU technology and incorporate advanced design technologies. The ACR NPP seismic design complies with Canadian standards that were specifically developed for nuclear seismic design and also with relevant International Atomic Energy Agency (IAEA) Safety Design Standards and Guides. However, since the ACR is also being offered to several markets with many potential sites and different regulatory environments, there is a need to develop a comprehensive approach for the seismic design input parameters. These input parameters are used in the design of the standard ACR product that is suitable for many sites while also maintaining its economic competitiveness. For this purpose, the ACR standard plant is conservatively qualified for a Design Basis Earthquake (DBE) with a peak horizontal ground acceleration of 0.3g for a wide range of soil/rock foundation conditions and Ground Response Spectra (GRS). These input parameters also address some of the current technical issues such as high frequency content and near field effects. In this paper, the ACR seismic design philosophy and seismic design approach for meeting the safety design requirements are reviewed. Also the seismic design

The ACR - Advanced CANDU Reactor, developed by Atomic Energy of Canada Limited (AECL), is designed with constructability considerations as a major requirement during all project phases from the concept design stage to the detail design stage. This necessitated a much more comprehensive approach in including constructability considerations in the design to ensure that the construction duration is met. For the ACR-700, a project schedule of 48 months has been developed for the nth replicated unit with a 36 month construction period duration from First Concrete to Fuel Load. An overall construction strategy that builds on the success of the construction methods that are proven in the construction of the Qinshan CANDU 6 project has been developed for the ACR. The overall construction strategy comprises the 'Open Top' construction technique using a Very Heavy Lift crane, parallel construction activities, with extensive modularization and prefabrication. In addition, significant applications of up to date construction technology will be implemented, e.g. large volume concrete pours, prefabricated rebar, use of climbing forms, composite structures, prefabricated permanent formwork, automatic welding, and utilization of the latest electronic technology tools such as 3D CADDs modelling yields a very high quality, clash free product to allow construction to be completed 'right the first time' and eliminates rework. Integration of 3D CADDs models and scheduling tools such as Primavera has allowed development of actual construction sequences and an iterative approach to schedule verification and improvement. Modularization and prefabrication are major features of the ACR design in order to achieve the project schedule. For the reactor building approximately 80% of the volume will be installed as modules or prefabricated assembles. This ensures critical path activities are achieved. This paper examines the advanced construction methods implemented in the design in order to

Functional relevance of AcrB Trimerization in pump assembly and substrate binding.

Directory of Open Access Journals (Sweden)

Wei Lu

Full Text Available AcrB is a multidrug transporter in the inner membrane of Escherichia coli. It is an obligate homotrimer and forms a tripartite efflux complex with AcrA and TolC. AcrB is the engine of the efflux machinery and determines substrate specificity. Active efflux depends on several functional features including proton translocation across the inner membrane through a proton relay pathway in the transmembrane domain of AcrB; substrate binding and migration through the substrate translocation pathway; the interaction of AcrB with AcrA and TolC; and the formation of AcrB homotrimer. Here we investigated two aspects of the inter-correlation between these functional features, the dependence of AcrA-AcrB interaction on AcrB trimerization, and the reliance of substrate binding and penetration on protein-protein interaction. Interaction between AcrA and AcrB was investigated through chemical crosslinking, and a previously established in vivo fluorescent labeling method was used to probe substrate binding. Our data suggested that dissociation of the AcrB trimer drastically decreased its interaction with AcrA. In addition, while substrate binding with AcrB seemed to be irrelevant to the presence or absence of AcrA and TolC, the capability of trimerization and conduction of proton influx did affect substrate binding at selected sites along the substrate translocation pathway in AcrB.

2017-01-01

To engineer cells for industrial-scale application, a deep understanding of how to design molecular control mechanisms to tightly maintain functional stability under various fluctuations is crucial. Absolute concentration robustness (ACR) is a category of robustness in reaction network models in which the steady-state concentration of a molecular species is guaranteed to be invariant even with perturbations in the other molecular species in the network. Here, we introduce a software tool, absolute concentration robustness explorer (ACRE), which efficiently explores combinatorial biochemical networks for the ACR property. ACRE has a user-friendly interface, and it can facilitate efficient analysis of key structural features that guarantee the presence and the absence of the ACR property from combinatorial networks. Such analysis is expected to be useful in synthetic biology as it can increase our understanding of how to design molecular mechanisms to tightly control the concentration of molecular species. ACRE is freely available at https://github.com/ramzan1990/ACRE.

To engineer cells for industrial-scale application, a deep understanding of how to design molecular control mechanisms to tightly maintain functional stability under various fluctuations is crucial. Absolute concentration robustness (ACR) is a category of robustness in reaction network models in which the steady-state concentration of a molecular species is guaranteed to be invariant even with perturbations in the other molecular species in the network. Here, we introduce a software tool, absolute concentration robustness explorer (ACRE), which efficiently explores combinatorial biochemical networks for the ACR property. ACRE has a user-friendly interface, and it can facilitate efficient analysis of key structural features that guarantee the presence and the absence of the ACR property from combinatorial networks. Such analysis is expected to be useful in synthetic biology as it can increase our understanding of how to design molecular mechanisms to tightly control the concentration of molecular species.

The Automated Conflict Resolution System (ACRS) is a mission-current scheduling aid that predicts periods of mutual interference when two or more orbiting spacecraft are scheduled to communicate with the same Tracking and Data Relay Satellite (TDRS) at the same time. The mutual interference predicted has the potential to degrade or prevent communications. Thus the ACRS system is a useful tool for aiding in the scheduling of Space Network (SN) communications.

Background Albuminuria is generally known as a sensitive marker of renal and cardiovascular dysfunction. It can be used to help predict the occurrence of nephropathy and cardiovascular disorders in diabetes. Individuals with prediabetes have a tendency to develop macrovascular and microvascular pathology, resulting in an increased risk of retinopathy, cardiovascular diseases, and chronic renal diseases. We evaluated the clinical value of a strip test for measuring the urinary albumin-to-creatinine ratio (ACR) in prediabetes and diabetes. Methods Spot urine samples were obtained from 226 prediabetic and 275 diabetic subjects during regular health checkups. Urinary ACR was measured by using strip and laboratory quantitative tests. Results The positive rates of albuminuria measured by using the ACR strip test were 15.5% (microalbuminuria, 14.6%; macroalbuminuria, 0.9%) and 30.5% (microalbuminuria, 25.1%; macroalbuminuria, 5.5%) in prediabetes and diabetes, respectively. In the prediabetic population, the sensitivity, specificity, positive predictive value, negative predictive value, and overall accuracy of the ACR strip method were 92.0%, 94.0%, 65.7%, 99.0%, and 93.8%, respectively; the corresponding values in the diabetic population were 80.0%, 91.6%, 81.0%, 91.1%, and 88.0%, respectively. The median [interquartile range] ACR values in the strip tests for measurement ranges of 300 mg/g were 9.4 [6.3-15.4], 46.9 [26.5-87.7], and 368.8 [296.2-575.2] mg/g, respectively, using the laboratory method. Conclusions The ACR strip test showed high sensitivity, specificity, and negative predictive value, suggesting that the test can be used to screen for albuminuria in cases of prediabetes and diabetes.

2014-07-01

The folding of a multi-domain trimeric α-helical membrane protein, Escherichia coli inner membrane protein AcrB, was investigated. AcrB contains both a transmembrane domain and a large periplasmic domain. Protein unfolding in sodium dodecyl sulfate (SDS) and urea was monitored using the intrinsic fluorescence and circular dichroism spectroscopy. The SDS denaturation curve displayed a sigmoidal profile, which could be fitted with a two-state unfolding model. To investigate the unfolding of separate domains, a triple mutant was created, in which all three Trp residues in the transmembrane domain were replaced with Phe. The SDS unfolding profile of the mutant was comparable to that of the wild type AcrB, suggesting that the observed signal change was largely originated from the unfolding of the soluble domain. Strengthening of trimer association through the introduction of an inter-subunit disulfide bond had little effect on the unfolding profile, suggesting that trimer dissociation was not the rate-limiting step in unfolding monitored by fluorescence emission. Under our experimental condition, AcrB unfolding was not reversible. Furthermore, we experimented with the refolding of a monomeric mutant, AcrBΔloop , from the SDS unfolded state. The CD spectrum of the refolded AcrBΔloop superimposed well onto the spectra of the original folded protein, while the fluorescence spectrum was not fully recovered. In summary, our results suggested that the unfolding of the trimeric AcrB started with a local structural rearrangement. While the refolding of secondary structure in individual monomers could be achieved, the re-association of the trimer might be the limiting factor to obtain folded wild-type AcrB. © 2014 The Protein Society.

Zhao, Yu; Liu, Xuehe; Xu, Ziyan; Yang, Hui; Li, Jixi

2017-07-22

Serine/threonine-protein kinase-like protein ARABIDOPSIS CRINKLY4 (ACR4), a transmembrane protein of Arabidopsis thaliana, plays important roles in cell division and differentiation. Although accumulating studies shed light on the function of ACR4, the structure and catalytic mechanism of ACR4 remain to be elucidated. Here, we report the purification and enzymatic properties of the intracellular kinase domain (residues 464-799) of ACR4 (ACR4 IKD ). Through Ni-affinity chromatography and gel filter chromatography methods, we successfully obtain high-purity ACR4 IKD protein from Escherichia coli. Dynamic light scattering and gel-filtration methods reveal that ACR4 IKD distributes with high homogeneity and exists as a monomer in solution. In addition, the ACR4 IKD protein has typical kinase activity with myelin basic protein (MBP) as the substrate. Our study may lay the foundation for structure determination of ACR4 IKD and further functional research, for example, screening significant substrates of ACR4 in Arabidopsis thaliana.

Full Text Available Honey from stingless bees (Melipona sp. is a nutritious and medicinal product economically valued in the informal Brazilian market, driven by the growing demand for natural products; however, its physicochemical characteristics are still unknown. Thus, the aim of this study is to evaluate the physicochemical profile of the stingless bee honey produced in Cruzeiro do Sul, Acre. Honey samples were analyzed following the methodology recommended by Ministério da Agricultura, Pecuária e Abastecimento; the following parameters were established: moisture, total sugars, reducing sugars, apparent sucrose, ash, crude protein, diastase activity, Brix degrees, free acidity, lactonic acidity, total acidity, pH, hydroxymethylfurfural, electrical conductivity, color and Lugol, Lund and Fiehe reactions. Results show that these parameters are not suitable for all samples, being incompatible with established standards, indicating that the current legislation on Apis mellifera is not suitable for all characters analyzed, mainly moisture content, corroborating the need to standardize guidelines for honey from stingless bees. Moreover, there was no tampering in the honeys analyzed.

Full Text Available Background Urinary tract infection (UTI is one of the most common infectious diseases and nosocomial infections worldwide, and uropathogenic Escherichia coli is the primary cause of UTI. Due to increased antibiotic resistance and the emergence of multidrug resistant (MDR UPEC clones, the treatment of UTI is difficult. The occurrence of MDR in E. coli has been attributed to the AcrAB-TolC complex of efflux pumps. Objectives The aim of this study was to complete a frequency evaluation of acrA and acrB genes among UPEC MDR strains isolated from patients with UTI who were admitted to Milad hospital in Tehran. Methods For 123 UPEC strains that were isolated and diagnosed from the urine samples of patients using biochemical tests, antibiotic susceptibility was carried out using the disc diffusion method according to CLSI guidelines. Isolates that were resistant to at least one antimicrobial agent in three or more of the categories were considered to be MDR. The presence and frequency of acrA and acrB genes was determined using PCR. Results The rates of antibiotic resistance to ampicillin, cefalotin, tetracycline, cefazolin, ceftriaxone, ceftizoxime, ceftazidime, ciprofloxacin, and cotrimoxazole were 82.9%, 78.1%, 61.1%, 49.5%, 38.2%, 30.2%, 26.1%, 42.2%, and 60.1%, respectively. The isolates were most sensitive to nitrofurantoin (95.9%, gentamicin (77.2%, and amikacin (71.5%. A total of 78% of the isolates were MDR. The frequency of the acrA gene was 82.90%, the acrB gene was 95.90% and acrA + acrB was 95.90%. There was no significant difference between acrA and acrB frequency relating to bacterial antibiotic resistance. Conclusions Our results showed that ways to control the treatment of UTI for the prevention of MDR occurrence should be sought. For a better study of efflux pumps, a comprehensive and detailed study regarding the presence of efflux pumps gees is required.

1993-01-01

The authors developed a computer program for automatic coding of ACR(American College of Radiology) code. The automatic coding of the ACR code is essential for computerization of the data in the department of radiology. This program was written in foxbase language and has been used for automatic coding of diagnosis in the Department of Radiology, Wallace Memorial Baptist since May 1992. The ACR dictionary files consisted of 11 files, one for the organ code and the others for the pathology code. The organ code was obtained by typing organ name or code number itself among the upper and lower level codes of the selected one that were simultaneous displayed on the screen. According to the first number of the selected organ code, the corresponding pathology code file was chosen automatically. By the similar fashion of organ code selection, the proper pathologic dode was obtained. An example of obtained ACR code is '131.3661'. This procedure was reproducible regardless of the number of fields of data. Because this program was written in 'User's Defined Function' from, decoding of the stored ACR code was achieved by this same program and incorporation of this program into program in to another data processing was possible. This program had merits of simple operation, accurate and detail coding, and easy adjustment for another program. Therefore, this program can be used for automation of routine work in the department of radiology

Atomic Energy of Canada Limited (AECL) has developed the ACR-1000 (Advanced CANDU Reactor-1000 ) to meet market expectations for enhanced safety of plant operation, high capacity factor, low operating cost, increased operating life, simple component replacement, reduced capital cost, and shorter construction schedule. The ACR-1000 design is based on the use of horizontal fuel channels surrounded by a heavy water moderator, the same feature as in all CANDU reactors. The major innovation in the ACR-1000 is the use of low enriched uranium fuel, and light water as the coolant, which circulates in the fuel channels. This results in a compact reactor core design and a reduction of heavy water inventory, both contributing to a significant decrease in capital cost per MWe produced. The ACR-1000 plant is a two-unit, integrated plant with each unit having a nominal gross output of about 1165 MWe with a net output of approximately 1085 MWe. The plant design is adaptable to a single unit configuration, if required. This paper focuses on the technical considerations that went into developing some of the important design requirements for the steam generators for the ACR-1000 plant and how these requirements are specified in the Technical Specification, which is the governing document for the steam generator (SG) detail design. Layout of these SGs in the plant is briefly described and their impacts on the SG design. (author)

To assess the trends of women in voluntary leadership roles in the ACR from 2001 to 2015. Retrospective leadership records from 2001 to 2015 were collected from the ACR Membership Database based on member demographics, gender, and participation in leadership roles at the national and state level. Data were sorted by gender and year to assess the proportion of women in each leadership position relative to total member/representation counts. Overall, there were increasing numbers of women represented in ACR leadership. From 2001 to 2015, there were increasing rates of women achieving fellowship in the College (7%-11%), now at parity with male member rates. Representation by women has risen from 7% to 21% for state chapter presidents and from 14% to 18% for state councilors. Comparing rolling 5-year averages from 2001-2005 and 2011-2015 showed statistically significant increases (P leadership roles. Women members of the council steering committee rose from 13% in 2001 to 19% in 2015, peaking at 24% in 2014. The Board of Chancellors (BOC) showed the largest increase in women, from 9% to 33%, with a peak at 37% in 2014. However, no BOC chairs were women, one council speaker was a woman, two women were ACR presidents, and two women were vice presidents.

Full text The Canadian nuclear technology has a long history dating back to the 1940s. In this regard, Canada is in a unique situation, shared only by a very few countries, where original nuclear power technology has been invented and further developed. Canadian Nuclear Safety Commission (CNSC), then called AECB, was established in 1946. CNSC focuses on nuclear security, nuclear safety, establishing health and safety regulations, and has also played an instrumental role in the formation of the IAEA. CNSC has provided assistance to the establishment of regulatory authorities in AECL's client countries such as Korea, Argentina, China and Romania. AECL has developed the Gen III+ ACR 1000 as evolutionary advancement of the current CANDU 6 reactor. ACR-1000 has evolved from AECL's in depth experience with CANDU systems, components, and materials, as well as the feedback received from owners and operators of CANDU plants. The ACR-1000 design retains the proven strengths and features of CANDU reactors, while incorporating innovations and state-of-the-art technology. It also features major improvements in economics, inherent safety characteristics, and performance. ACR-1000 has completed its Basic Engineering, has advanced in the licensing process in Canada, and is ready for deployment in Canadian and world markets. EC6 is an evolution of CANDU 6 and is a Gen III natural uranium fuelled reactor. Its medium size and potential for fuel localization and advanced fuel cycles is an optimal strategic solution in many markets.AECL's reactor products are shown to be compliant with a variety of licensing and regulatory requirements. These include the new CNSC DRD-337, IAEA NS-R1, and EUR. This allows the countries interested in CANDU reactor products to be confident of its licensing in their own regulatory regimes.

Todavia, uma vez inseridas na tradição ritual, essas histórias do passado se fundem e condensam em imagens complexas. Dois processos parecem operantes na elaboração dessas imagens: um tende a obliterar o fato externo para inseri-lo em um quadro conceitual indígena (a cosmologia do mundo sobrenatural; o outro emprega as ambigüidades da cosmologia para representar um aspecto saliente dos recém-chegados. O resultado é um elaborado (e ritualmente poderoso "engrama" da tradição ritual, que passa a constituir uma parte significativa da memória social.

Laure Emperaire

Full Text Available Resumo A diversidade de plantas cultivadas, selecionadas e conservadas pelos agricultores tradicionais, é de interesse tanto local quanto nacional, além de constituir um patrimônio biológico e cultural. No caso da Amazônia, apesar de atualmente dispormos de uma suma de dados sobre a agrobiodiversidade, a diversidade das opções metodológicas mobilizadas torna difícil uma visão sintética de suas dinâmicas. Para entendê-las, torna-se imprescindível assegurar um monitoramento, em longo prazo, de localidades sentinelas ou observatórios, e construir indicadores a serem compartilhados entre populações locais, pesquisadores e formuladores de políticas públicas. Como exemplo, propomos uma abordagem exploratória da agrobiodiversidade levantada junto a 52 agricultores de duas comunidades da região de Cruzeiro do Sul (Acre, a partir de uma abordagem qualitativa sobre as formas locais de denominação das plantas e quantitativa, fundamentada sobre a medida da riqueza (número de espécies ou variedades presentes. A amplitude da riqueza é de 338 plantas, principalmente variedades locais, levantadas com uma alta frequência de espécies ou de variedades apenas cultivadas por um ou dois agricultores, sua estruturação é marcada pela presença de um modelo aninhado, sendo evidenciado o núcleo de plantas de maior coesão.

Elgohary, M.; Fairclough, N.; Ricciuti, R.

2003-01-01

AECL has recognised the importance of Constructability for many years and is applying its principals to CANDU projects with increasing success. Constructability is defined as the consideration of construction knowledge and experience during all phases of a project, and recognizes that maximum benefit can be achieved during the concept phases of a project. The CANDU 6 Nuclear Power Plant has been constructed eleven times in the last 25 years, however, the last two units being completed on the Qinshan project in China have employed some very innovative construction methods that have not been used on the previous units. In order to make nuclear power generation more competitive, shorter construction schedules and reduced project costs and risks are essential objectives. The application of constructability principles is a major contributor to achieving these objectives. The success of Qinshan has increased the confidence in the new construction methods which are being implemented on the ACR (Advanced CANDU Reactor) successfully. An ACR construction strategy that utilizes advanced construction techniques has been developed by AECL. The strategy includes paralleling of activities by using extensive modularization and the vertical installation of equipment and modules into the reactor building, using a VHL (Very Heavy Lift) crane. This strategy allows short schedules to be met with a minimum risk to the project. This paper describes the latest construction methods used successfully on the Qinshan CANDU 6 project and looks at the extensive implementation of similar methods for ACR. It is concluded, based on the Qinshan success, that the ACR construction schedule is readily achievable. (author)

Expression of the AcrAB Components of the AcrAB-TolC Multidrug Efflux Pump of Yersinia enterocolitica Is Subject to Dual Regulation by OmpR.

Directory of Open Access Journals (Sweden)

Full Text Available OmpR is a transcriptional regulator implicated in the control of various cellular processes and functions in Enterobacteriaceae. This study was undertaken to identify genes comprising the OmpR regulon in the human gastrointestinal pathogen Yersinia enterocolitica. Derivatives of an ompR-negative strain with random transposon insertions creating transcriptional fusions with the reporter gene lacZ were isolated. These were supplied with the wild-type ompR allele in trans and then screened for OmpR-dependent changes in β-galactosidase activity. Using this strategy, five insertions in genes/operons positively regulated by OmpR and two insertions in genes negatively regulated by this protein were identified. Genetic analysis of one of these fusion strains revealed that the gene acrR, encoding transcriptional repressor AcrR is negatively regulated by OmpR. Differential analysis of membrane proteins by SDS-PAGE followed by mass spectrometry identified the protein AcrB, a component of the AcrAB-TolC multidrug efflux pump, as being positively regulated by OmpR. Analysis of the activity of the acrR and acrAB promoters using gfp fusions confirmed their OmpR-dependent repression and activation, respectively. The identification of putative OmpR-binding sites and electrophoretic mobility shift assays confirmed that this regulator binds specifically to both promoter regions with different affinity. Examination of the activity of the acrR and acrAB promoters after the exposure of cells to different chemicals showed that bile salts can act as an OmpR-independent inducer. Taken together, our findings suggest that OmpR positively controls the expression of the AcrAB-TolC efflux pump involved in the adaptive response of Y. enterocolitica O:9 to different chemical stressors, thus conferring an advantage in particular ecological niches.

The aim of this work was to use the nuclear methodology to character pottery discovered inside archaeological sites recognized with circular earth structure in Acre State - Brazil which may contribute to the research in the reconstruction of part of the pre-history of the Amazonic Basin. The sites are located mainly in the Hydrographic Basin of High Purus River. Three of them were strategic chosen to collect the ceramics: Lobao, in Sena Madureira County at north; Alto Alegre in Rio Branco County at east and Xipamanu I, in Xapuri County at south. Neutron Activation Analysis in conjunction with multivariate statistical methods were used for the ceramic characterization and classification. An homogeneous group was established by all the sherds collected from Alto Alegre and was distinct from the other two groups analyzed. Some of the sherds collected from Xipamunu I appeared in Lobao's urns, probably because they had the same fabrication process. (author)

Structural and functional aspects of the multidrug efflux pump AcrB.

Eicher, Thomas; Brandstätter, Lorenz; Pos, Klaas M

2009-08-01

The tripartite efflux system AcrA/AcrB/TolC is the main pump in Escherichia coli for the efflux of multiple antibiotics, dyes, bile salts and detergents. The inner membrane component AcrB is central to substrate recognition and energy transduction and acts as a proton/drug antiporter. Recent structural studies show that homotrimeric AcrB can adopt different monomer conformations representing consecutive states in an allosteric functional rotation transport cycle. The conformational changes create an alternate access drug transport tunnel including a hydrophobic substrate binding pocket in one of the cycle intermediates.

Background. Magnetic resonance imaging (MRI) instrumentation is vulnerable to technical and image quality problems, and quality assurance is essential. In the studied regional imaging center the long-term quality assurance has been based on MagNET phantom measurements. American College of Radiology (ACR) has an accreditation program including a standardized image quality measurement protocol and phantom. The ACR protocol includes recommended acceptance criteria for clinical sequences and thus provides possibility to assess the clinical relevance of quality assurance. The purpose of this study was to test the ACR MRI phantom in quality assurance of a multi-unit imaging center. Material and methods. The imaging center operates 11 MRI systems of three major manufacturers with field strengths of 3.0 T, 1.5 T and 1.0 T. Images of the ACR phantom were acquired using a head coil following the ACR scanning instructions. Both ACR T1- and T2-weighted sequences as well as T1- and T2-weighted brain sequences in clinical use at each site were acquired. Measurements were performed twice. The images were analyzed and the results were compared with the ACR acceptance levels. Results. The acquisition procedure with the ACR phantom was faster than with the MagNET phantoms. On the first and second measurement rounds 91% and 73% of the systems passed the ACR test. Measured slice thickness accuracies were not within the acceptance limits in site T2 sequences. Differences in the high contrast spatial resolution between the ACR and the site sequences were observed. In 3.0 T systems the image intensity uniformity was slightly lower than the ACR acceptance limit. Conclusion. The ACR method was feasible in quality assurance of a multi-unit imaging center and the ACR protocol could replace the MagNET phantom tests. An automatic analysis of the images will further improve cost-effectiveness and objectiveness of the ACR protocol

[Child prostitution: family disintegration, necessary planning, the laziness of the elite].

Science.gov (United States)

1993-09-01

Child and juvenile prostitution in Brazil has reached such proportions that a parliamentary commission launched an inquiry. The Brazilian Center of Children and Adolescents (CBIA) estimated that there are about 500,000 such prostitutes in the country, a record in Latin America. This type of prostitution flourishes in poor urban areas and in the North and Central-East. Not only girls become prostitutes; in Rio de Janeiro, 4000 boys cater to tourists from the industrialized world. 79% of these youngsters say that they use condoms, but 42% are infected with HIV. In many cases their families tolerate their homosexual encounters because of the extra income received. In the interior of the state of Rio, girls aged 11-15 years are enticed to cities as domestics and end up in prostitution. In Niteroi there is a prostitution network specializing in 13-year-old girls. Although there are 30,000 prostitutes in the state of Rio, the distribution of condoms among them has caused negative reactions among conservatives and Catholics claiming that it would increase licentiousness. The Brazilian Center for the Defense of the Rights of Children and Adolescents countered that condoms help prevent the spread of diseases. In Para, Acre, and Rondonia, 13-, 14-, and 15-year-old girls sell their bodies in order to survive. In the maternity ward of Barbara Heliodora, Rio Branco, Acre, 31% of deliveries are to girls aged 10-16 years. In Sao Paulo and in the neighborhoods of Bras and Belem, girls as young as 10 years of age become prostitutes under the protection of corrupt police who exact sexual favors or a share of receipts. According to CBIA, 80% of sexual violence against children and adolescents occurs in the home, with fathers being the main aggressors. The prostitution of children and adolescents in Brazil is connected to the destruction of the family and is the result of misery and hunger.

A goal of an imaging accreditation program is to ensure adequate image quality, verify appropriate staff qualifications, and to assure patient and personnel safety. Currently, more than 35,000 facilities in 10 modalities have been accredited by the American College of Radiology (ACR), making the ACR program one of the most prolific accreditation options in the U.S. In addition, ACR is one of the accepted accreditations required by some state laws, CMS/MIPPA insurance and others. Familiarity with the ACR accreditation process is therefore essential to clinical diagnostic medical physicists. Maintaining sufficient knowledge of the ACR program must include keeping up-to-date as the various modality requirements are refined to better serve the goals of the program and to accommodate newer technologies and practices. This session consists of presentations from authorities in four ACR accreditation modality programs, including magnetic resonance imaging, computed tomography, nuclear medicine, and mammography. Each speaker will discuss the general components of the modality program and address any recent changes to the requirements.

Drug transport mechanism of the AcrB efflux pump.

Science.gov (United States)

Pos, Klaas M

2009-05-01

In Gram-negative bacteria such as Escherichia coli and Pseudomonas aeruginosa, tripartite multidrug efflux systems extrude cytotoxic substances from the cell directly into the medium bypassing periplasm and the outer membrane. In E. coli, the tripartite efflux system AcrA/AcrB/TolC is the pump that extrudes multiple antibiotics, dyes, bile salts and detergents. The inner membrane component AcrB, a member of the Resistance Nodulation cell Division (RND) family, is the major site for substrate recognition and energy transduction of the entire tripartite system. The drug/proton antiport processes in this secondary transporter are suggested to be spatially separated, a feature frequently observed for primary transporters like membrane-bound ATPases. The recently elucidated asymmetric structure of the AcrB trimer reveals three different monomer conformations proposed to represent consecutive states in a directional transport cycle. Each monomer shows a distinct tunnel system with entrances located at the boundary of the outer leaflet of the inner membrane and the periplasm through the periplasmic porter (pore) domain towards the funnel of the trimer and TolC. In one monomer a hydrophobic pocket is present which has been shown to bind the AcrB substrates minocyclin and doxorubicin. The energy conversion from the proton motive force into drug efflux includes proton binding in (and release from) the transmembrane part. The conformational changes observed within a triad of essential, titratable residues (D407/D408/K940) residing in the hydrophobic transmembrane domain appear to be transduced by transmembrane helix 8 and associated with the conformational changes seen in the periplasmic domain. From the asymmetric structure a possible peristaltic pump transport mechanism based on a functional rotation of the AcrB trimer has been postulated. The novel drug transport model combines the alternate access pump mechanism with the rotating site catalysis of F(1)F(o) ATPase as

Nuclear Power Plant (NPP) simulators are the main means for operator training and as such are a crucial part of the NPP operation life-cycle. Hitachi, Ltd., Information and Control Systems Company (henceforth 'Hitachi') is the preferred DCS and DCS emulator developer and supplier for the ACR-1000 NPP control system. Hitachi's concept for the DCS (distributed control system) portion of the ACR-1000 simulator is 'total emulation of the DCS' by software. This paper will review the current status of the technical development and the major project milestones. (author)

Burnup dependence of coolant void reactivity for ACR-1000 cell

The Advanced Candu Reactor (ACR-1000) is light water cooled, fueled with enriched uranium and has a smaller lattice pitch than the Candu-6. As a result, the neutronic behavior of the ACR-1000 cell is expected to be somewhat different from that of the Candu-6 leading to a negative coolant void reactivity (CVR). Here we evaluate the CVR for the ACR-1000 cell using the lattice code DRAGON and compare our results with those obtained using the code WIMS-AECL. The differences observed between these two codes for the burnup dependence of the CVR is mainly explained in terms of the specific cell leakage model used by both codes. (authors)

Fibromyalgia (FM) may occur with rheumatoid arthritis (RA) and systemic sclerosis (SSc), and debate remains about its diagnosis. We aimed to use three FM tools (a screening tool (FiRST), diagnostic criteria (ACR 1990 and revised 2010), to compare FM prevalence between RA and SSc patients, to describe the phenotypes of patients with comorbid FM, and to analyze links between FM and secondary Sjögren's syndrome (SS). Consecutive adult patients with confirmed RA or SSc from four university hospitals were tested with the three FM tools. FiRST detected FM in 22.6% of the 172 RA patients, with confirmation in 22.1% (ACR1990) and 19.1% (ACR2010). ACR1990FM+ RA patients had more diffuse pain, whereas ACR2010FM+ RA patients had higher BMI and pain intensity, more diffuse pain, active disease, disability, and associated SS. FiRST detected FM in 27.8% of the 122 SSc patients, with confirmation in 30.3% (ACR1990) and 23.7% (ACR2010). ACR1990FM+ SSc patients had greater disability and pain intensity, and more diffuse pain, whereas ACR2010FM+ SSc patients had higher BMI, pain intensity, more disability and diffuse pain, and associated SS. Correlations between FM diagnostic and screening tool results were modest in both conditions. Secondary SS was associated with comorbid FM. The prevalence of FM is high in SSc and RA, whatever the FM diagnostic tool used. Secondary SS is associated with FM in both RA and SSc. The revised ACR 2010 FM criteria and FiRST screening tool reveal specific phenotypes potentially useful for improving disease management.

Full Text Available O quiabeiro é suscetível a várias doenças que podem causar prejuízos ao agricultor, caso não sejam manejadas. Objetivaram-se avaliar o efeito da temperatura e a reação de genótipos de quiabeiro ao mofo branco. Plantas de 30 dias inoculadas na região do colo, com e sem ferimento, com dois isolados de Sclerotinia sclerotiorum, foram mantidas por duas semanas nas temperaturas de 15; 20; 25; 30 ou 35ºC. Quatorze genótipos de quiabeiro com um e dois meses de emergência, assim como frutos no ponto de colheita comercial tiveram seus comportamentos avaliados quanto à doença. Avaliaram-se a incidência de plantas com tombamento ou mortas e o comprimento da lesão nos frutos inoculados. A doença foi favorecida por temperaturas entre 15 e 20ºC e, de maneira geral, não foram observadas diferenças entre os isolados e influência do ferimento na ocorrência da doença. Não foram encontrados genótipos de quiabeiro resistentes ao mofo branco, pois todos apresentaram incidência superior a 30% de plantas mortas, sendo as plantas mais novas mais suscetíveis, e comprimento de lesão nos frutos >6,0 cm. Entretanto, diferenças de suscetibilidade entre os genótipos foram observadas em plantas de 30 e de 60 dias e podem ser informações úteis aos produtores para escolha de cultivares em clima ameno, assim como ser exploradas em programas de melhoramento.

To examine whether the ACR phantom could be used in quality standards for magnetic resonance imaging (MRI) instruments in Korea. We conducted the phantom test using the ACR MRI phantom in 20 MRI instruments currently used in Korea. According to ACR criteria, we acquired the phantom images which were then assessed by the following seven tests: geometric accuracy, high spatial resolution, slice thickness accuracy, slice position accuracy, image intensity uniformity, percent signal ghosting, and low contrast object detectability. The phantom images were interpreted by three experienced radiologists according to ACR criteria. Then, we examined the failure rate of each test and evaluated the inter-observer variation in the measurements and test failure. The failure rate of each test could be broken into the following components: geometric accuracy (11-21%), high contrast spatial resolution (10-15%), slice thickness accuracy(6-22%), slice position accuracy (5-17%), image intensity uniformity (6%), percent signal ghosting (16%), and low contrast object detectability (8-10%). In this series, all the failure rates were less than 30%. In addition, no inter-observer variation was seen in the measurements and test failure. ACR MRI phantom promises to be established as the standard phantom for MRI instruments in Korea because of its objectivity in assessing the phantom images

This paper gives a summary of the validation of the reactor physics codes WIMS-AECL, DRAGON, RFSP and MCNP5, which are being used in the design, operation, and safety analysis of the ACR-1000 R . The standards and guidelines being followed for code validation of the suite are established in CSA Standard N286.7-99 and ANS Standard ANS-19.3-2005. These codes are being validated for the calculation of key output parameters associated with various reactor physics phenomena of importance during normal operations and postulated accident conditions in an ACR-1000 reactor. Experimental data from a variety of sources are being used for validation. The bulk of the validation data is from critical experiments in the ZED-2 research reactor with ACR-type lattices. To supplement and complement ZED-2 data, qualified and applicable data are being taken from other power and research reactors, such as existing CANDU R units, FUGEN, NRU and SPERT research reactors, and the DCA critical facility. MCNP simulations of the ACR-1000 are also being used for validating WIMS-AECL/ DRAGON/RFSP, which involves extending the validation results for MCNP through the assistance of TSUNAMI analyses. Code validation against commissioning data in the first-build ACR-1000 will be confirmatory. The code validation is establishing the biases and uncertainties in the calculations of the WIMS-AECL/DRAGON/RFSP suite for the evaluation of various key parameters of importance in the reactor physics analysis of the ACR-1000.

Although its levels of catechins are higher than those of green tea (derived from the same plant, there are no studies addressing the relationship between this tea and obesity associated with oxidative stress.The objective of this study was to evaluate the effect of white tea on obesity and its complications using a diet induced obesity model. Forty male C57BL/6 mice were fed a high-fat diet to induce obesity (Obese group or the same diet supplemented with 0.5% white tea extract (Obese + WTE for 8 weeks. Adipose tissue, serum lipid profile, and oxidative stress were studied. White tea supplementation was not able to reduce food intake, body weight, or visceral adiposity. Similarly, there were no changes in cholesterol rich lipoprotein profile between the groups. A reduction in blood triacylglycerols associated with increased cecal lipids was observed in the group fed the diet supplemented with white tea. White tea supplementation also reduced oxidative stress in liver and adipose tissue. In conclusion, white tea extract supplementation (0.5% does not influence body weight or adiposity in obese mice. Its benefits are restricted to the reduction in oxidative stress associated with obesity and improvement of hypertriacylglycerolemia.O chá branco é um chá não fermentando feito a partir de brotos jovens da Camellia sinensis protegidos da luz solar para evitar a degradação de polifenóis.

The goal of this study is to compare the overall quality of film mammograms taken according to the Korean standards with the American College of Radiology (ACR) standard for clinical image evaluation and to identify means of improving mammography quality in Korea. Four hundred and sixty eight sets of film mammograms were evaluated with respect to the Korean and ACR standards for clinical image evaluation. The pass and failure rates of mammograms were compared by medical facility types. Average scores in each category of the two standards were evaluated. Receiver operating characteristic curve analysis was used to identify an optimal Korean standard pass mark by taking the ACR standard as the reference standard. 93.6% (438/468) of mammograms passed the Korean standard, whereas only 80.1% (375/468) passed the ACR standard (p < 0.001). Non-radiologic private clinics had the lowest pass rate (88.1%: Korean standard, 71.8%: ACR standard) and the lowest total score (76.0) by the Korean standard. Average scores of positioning were lowest (19.3/29 by the Korean standard and 3.7/5 by the ACR standard). A cutoff score of 77.0 for the Korean standard was found to correspond to a pass level when the ACR standard was applied. We suggest that tighter regulations, such as, raising the Korean pass mark, subtracting more for severe deficiencies, or considering a very low scores in even a single category as failure, are needed to improve the quality of mammography in Korea

To evaluate the technical quality of breast ultrasound based on American College of Radiology(ACR) standards. Between March 2002 and July 2002, ninety three breast sonograms obtained from 73 institutions were evaluated based on ACR standards for the hardware, technical settings, labeling of the images and identification. Of 93 breast sonograms, a satisfactory compliance with all ACR standards in the performance of breast US examinations was documented in 31% while the remaining 69% did not fully meet all ACR standards. 4.3% of breast US examinations were performed with a convex transducers, and the focal zone was inappropriately positioned in 14.2%. Gray-scale gain was subjectively characterized as inappropriate in 26.9%, and the size of lesion was not measured in 7.5%. Anatomic location of lesions was inappropriately described in 9.3%. The orientation of an US transducer was not properly labeled on any images in 33.3%. Inadequate recording of patient's information was noted in 43.3%. 50% of sonograms at University medical centers and larger general hospitals fully met all ACR standards while 36.8% at radiologic clinics and 12.1% at other private clinics met all ACR standards. Overall, 69% of breast sonograms failed to meet the quality criteria of the ACR standards. Therefore, it is essential to educate the basic technical details in performing breast US for the quality control.

pH-induced conformational changes of AcrA, the membrane fusion protein of Escherichia coli multidrug efflux system.

The multidrug efflux system AcrA-AcrB-TolC of Escherichia coli expels a wide range of drugs directly into the external medium from the bacterial cell. The mechanism of the efflux process is not fully understood. Of an elongated shape, AcrA is thought to span the periplasmic space coordinating the concerted operation of the inner and outer membrane proteins AcrB and TolC. In this study, we used site-directed spin labeling (SDSL) EPR (electron paramagnetic resonance) spectroscopy to investigate the molecular conformations of AcrA in solution. Ten AcrA mutants, each with an alanine to cysteine substitution, were engineered, purified, and labeled with a nitroxide spin label. EPR analysis of spin-labeled AcrA variants indicates that the side chain mobilities are consistent with the predicted secondary structure of AcrA. We further demonstrated that acidic pH induces oligomerization and conformational change of AcrA, and that the structural changes are reversible. These results suggest that the mechanism of action of AcrA in drug efflux is similar to the viral membrane fusion proteins, and that AcrA actively mediates the efflux of substrates.

Coarse-grained Simulations of Substrate Export through Multidrug Efflux Transporter AcrB

Science.gov (United States)

Jewel, Yead; Dutta, Prashanta; Liu, Jin

2017-11-01

The treatment of bacterial infectious diseases hampered by the overexpression of multidrug resistance (MDR) systems. The MDR system actively pumps the antibiotic drugs as well as other toxic compounds out of the cells. During the pumping, AcrB (one of the key MDR components) undergoes a series of large-scale proton/substrate dependent conformational changes. In this work, we implement a hybrid coarse-grained PACE force field that couples the united-atom protein model with the coarse-grained MARTINI water/lipid, to investigate the conformational changes of AcrB. We first develop the substrate force field which is compatible with PACE, then we implement the force field to explore large scale structural changes of AcrB in microsecond simulations. The effects of the substrate and the protonation states of two key residues: Asp407 and Asp408, are investigated. Our results show that the drug export through AcrB is proton as well as substrate dependent. Our simulations explain molecular mechanisms of substrate transport through AcrB complex, as well as provide valuable insights for designing proper antibiotic drugs.

Full Text Available Grandes investimentos em tecnologia de informação (TI vêm sendo canalizados para a melhoria dos processos empresariais. Esses investimentos limitam-se, em geral, à automação pura e simples dos processos já existentes na companhia, os quais continuam sendo realiza-dos pelos mesmos profissionais e regidos pelos mesmos princípios anteriores à TI. Um corolário deste tipo de automação é o pequeno ganho de produtividade do trabalho de colarinho branco. Uma alternativa para este problema é a reengenharia de processos, que por meio do uso criativo da TI e da gestão por processos procura estabelecer novas formas muito mais eficientes de realizar o trabalho. Entretanto, tais formas alteram, freqüente e fundamentalmente, o perfil do profissional e a natureza de seu trabalho. É sobre estes impactos que estaremos discorrendo ao longo deste artigo.Huge investiments in information technology (IT have been directed to business process improvements. Generally, such investments are limited to the sole automation of already existing processes, which continue to be performed according to the same rules and by the same professionals prior to IT. A consequence of this kind of automation is the low producti-vity increase in white collar work. An alternative to this problem is business process reengi-neering, which, via the creative use of IT, strives to establish much more effective ways of performing work. However, very often such new ways affect the professional skills and the nature of the work. This paper discusses the impacts of IT on white collar work.

Full Text Available Even with planning and careful use of natural resources, and specially in the case of water courses, some areas are negatively modified, due to losing of margin or hillside stability, leading to erosions and slides. On this way, revegetation and stabilization techniques are imposing tasks to these areas. Some non expensive and easy biological techniques are already known, resting to investigate the applicability of adequate materials to each area, as well as biotechnical value of local native species. This works deals with investigating, on field situation, the rooting stick capability of two different species, that are common on water courses edges of the studied region: ‘sarandi-branco’ (Phyllanthus sellowianus Müll. Arg. and ‘vime’ (Salix viminalis L.. The experiment was developed on eroded margin of ‘Guarda-mor’ stream, in central area of ‘Rio Grande do Sul’ State, Brazil. The sticks used were from different parts of branches (base, half and tip. Sixty day after planting, the rooting was evaluated, being found a good revegetation capability of both species. On ‘sarandibranco’ sticks, the rooting reached 78%, being significantly higher than on ‘vime’ sticks (69%. To both species, the rooting rose up with the proximity of water level and with increasing diameter of sticks (base > half > tip.

Hydrogeology, water resources, and water budget of the upper Rio Hondo Basin, Lincoln County, New Mexico, 2010

Darr, Michael J.; McCoy, Kurt J.; Rattray, Gordon W.; Durall, Roger A.

2014-01-01

The upper Rio Hondo Basin occupies a drainage area of 585 square miles in south-central New Mexico and comprises three general hydrogeologic terranes: the higher elevation “Mountain Block,” the “Central Basin” piedmont area, and the lower elevation “Hondo Slope.” As many as 12 hydrostratigraphic units serve as aquifers locally and form a continuous aquifer on the regional scale. Streams and aquifers in the basin are closely interconnected, with numerous gaining and losing stream reaches across the study area. In general, the aquifers are characterized by low storage capacity and respond to short-term and long-term variations in recharge with marked water-level fluctuations on short (days to months) and long (decadal) time scales. Droughts and local groundwater withdrawals have caused marked water-table declines in some areas, whereas periodically heavy monsoons and snowmelt events have rapidly recharged aquifers in some areas. A regional-scale conceptual water budget was developed for the study area in order to gain a basic understanding of the magnitude of the various components of input, output, and change in storage. The primary input is watershed yield from the Mountain Block terrane, supplying about 38,200 to 42,300 acre-feet per year (acre-ft/yr) to the basin, as estimated by comparing the residual of precipitation and evapotranspiration with local streamgage data. Streamflow from the basin averaged about 21,200 acre-ft/yr, and groundwater output left the basin at an estimated 2,300 to 5,700 acre-ft/yr. The other major output (about 13,500 acre-ft/yr) was by public water supply, private water supply, livestock, commercial and industrial uses, and the Bonito Pipeline. The residual in the water budget, the difference between the totals of the input and output terms or the potential change in storage, ranged from -2,200 acre-ft/yr to +5,300 acre-ft/yr. There is a high degree of variability in precipitation and consequently in the water supply; small

Structures of Gate Loop Variants of the AcrB Drug Efflux Pump Bound by Erythromycin Substrate.

Directory of Open Access Journals (Sweden)

Abdessamad Ababou

Full Text Available Gram-negative bacteria such as E. coli use tripartite efflux pumps such as AcrAB-TolC to expel antibiotics and noxious compounds. A key feature of the inner membrane transporter component, AcrB, is a short stretch of residues known as the gate/switch loop that divides the proximal and distal substrate binding pockets. Amino acid substitutions of the gate loop are known to decrease antibiotic resistance conferred by AcrB. Here we present two new AcrB gate loop variants, the first stripped of its bulky side chains, and a second in which the gate loop is removed entirely. By determining the crystal structures of the variant AcrB proteins in the presence and absence of erythromycin and assessing their ability to confer erythromycin tolerance, we demonstrate that the gate loop is important for AcrB export activity but is not required for erythromycin binding.

Full Text Available Dentin hypersensitivity is a common painful condition observed in clinics. Dietary habits have been much associated with its development and persistence during and following periodontal treatment. The aim of this in vitro study was to evaluate the influence of vinegars on the removal of smear layer and exposure of dentinal tubules. Extracted human teeth were submitted to manual scaling with Gracey curettes in order to remove the cementum as well as to form a smear layer. Dentin samples with 3 mm² were obtained and distributed into six experimental groups: one control and five types of vinegars (alcohol, apple, rice, white wine and balsamic. Each group included two methods of vinegar application: topical and friction. After routine preparation for SEM analysis, photomicrographs were assessed by a calibrated and blind examiner using an appropriate index system. Kruskal-Wallis test indicated a significant influence of vinegars on smear layer removal. There was a statistically significant difference between groups treated with apple, white and rice vinegars and the control group (p A hipersensibilidade dentinária cervical é uma condição dolorosa muito comum nos consultórios.

The application of ZED-2 data in the design and analysis of the ACR-1000

International Nuclear Information System (INIS)

Dweiri, Y.

2011-01-01

The presentation discusses how data obtained from experiments performed in the ZED-2 Critical Facility at Atomic Energy of Canada Limited's Chalk River Laboratories is used in the design and analysis of the ACR-1000. The ACR-1000 design is an evolutionary advancement of the well-established CANDU Reactor technology to Generation 3+. When key core physics parameters for the ACR-1000 are calculated, biases and uncertainties in using the reactor physics toolset WIMS AECL/DRAGON/RFSP and MCNP must be quantified to be able to appropriately assess safety margins in the design. A unique feature of ZED-2 is the ability to perform a wide variety of experiments which is important in providing data that is used in the design and analysis of the ACR-1000. The ACR-1000 was designed to have a small and slightly negative coolant-void-reactivity (CVR), which provides an inherent safety characteristic to mitigate the reactivity transient under any postulated loss-of-coolant accident (LOCA) scenarios. The bias and uncertainty for CVR (full and checkerboard) calculations, derived through comparisons with experimental data, is pivotal to assess the accuracy of the predicted CVR value. This bias and uncertainty is also used in important LOCA analysis to demonstrate the safety features of the ACR-1000. This crucial physics information is available through experiments performed in ZED-2. Other important data that is obtained from ZED-2 in assessing core design pertains to end-flux peaking and in-core flux detector response. The end-region configuration of ACR fuel bundles is an important component of the design, as the axial power distribution within the bundle is not uniform. Detector response in an ACR flux spectrum is important to determine the suitability of safety system detectors when used in the ACR-1000 core. These applications demonstrate the versatility of ZED-2 in providing important reactor physics data makes this critical facility indispensible in current and future R and D

Full Text Available O presente trabalho teve por objetivo caracterizar o crescimento, o desenvolvimento e a produção de sementes da planta daninha capim-branco (Chloris polydactyla. Para isso, foram realizadas 16 avaliações periódicas de crescimento, quantificando-se fenologia, área foliar e massa seca (total, parte aérea e raízes das plantas. Foram, também, calculadas as taxas de crescimento absoluto (G e relativo (R. Quantificaram-se o número de racemos florais de 28 plantas, o comprimento de 100 racemos aleatórios e o número de sementes presentes em 100 unidades de 10 mm de racemo, após o florescimento. Observou-se que o capim-branco é uma espécie com desenvolvimento e crescimento iniciais lentos, uma vez que iniciou o florescimento e a posterior produção de sementes apenas aos 112 dias após a semeadura. Trata-se de uma espécie com grande potencial final de crescimento e produção de sementes, uma vez que um único perfilho e toda a planta foram capazes de produzir mais de 3.000 e 30.000 sementes, respectivamente. O crescimento inicial lento dessa planta daninha pode desfavorecer a competição interespecífica no interior dos campos agrícolas, em especial na cultura da cana-de-açúcar, onde é encontrada com maior freqüência, colonizando carreadores e bordas de talhão. No entanto, sua alta produção de sementes sugere ser uma planta daninha que poderá aumentar em importância na cultura.This experiment aimed to characterize growth, development and seed production of the weed Chloris polydactyla.

Using the ACR/NEMA standard with TCP/IP and Ethernet

Chimiak, William J.; Williams, Rodney C.

1991-07-01

There is a need for a consolidated picture archival and communications system (PACS) in hospitals. At the Bowman Gray School of Medicine of Wake Forest University (BGSM), the authors are enhancing the ACR/NEMA Version 2 protocol using UNIX sockets and TCP/IP to greatly improve connectivity. Initially, nuclear medicine studies using gamma cameras are to be sent to PACS. The ACR/NEMA Version 2 protocol provides the functionality of the upper three layers of the open system interconnection (OSI) model in this implementation. The images, imaging equipment information, and patient information are then sent in ACR/NEMA format to a software socket. From there it is handed to the TCP/IP protocol, which provides the transport and network service. TCP/IP, in turn, uses the services of IEEE 802.3 (Ethernet) to complete the connectivity. The advantage of this implementation is threefold: (1) Only one I/O port is consumed by numerous nuclear medicine cameras, instead of a physical port for each camera. (2) Standard protocols are used which maximize interoperability with ACR/NEMA compliant PACSs. (3) The use of sockets allows a migration path to the transport and networking services of OSIs TP4 and connectionless network service as well as the high-performance protocol being considered by the American National Standards Institute (ANSI) and the International Standards Organization (ISO) -- the Xpress Transfer Protocol (XTP). The use of sockets also gives access to ANSI's Fiber Distributed Data Interface (FDDI) as well as other high-speed network standards.

The aim of this study was to assess the status of the radiology job market as represented by the ACR Jobs Board from October 2010 to June 2013. With the assistance of the ACR, data from the ACR Jobs Board from October 2010 through June 2013, including the numbers of monthly new job seekers, new job postings, and job posting clicks, were gathered and used to calculate a monthly competitive index, defined as the ratio of new job seekers to new job postings. During the study period, the mean number of new job seekers was 168 per month, which was significantly greater than the 84 average new job postings for any given month (P = .0002). There was no significant difference between 2011 and 2012 with regard to the number of new job seekers or job postings. Over the time period assessed, more new job seekers registered in October and November 2010, August to November 2011, and October and November 2012. These periods were also associated with the highest competitive index values. There were less job seekers in the winter and spring of 2011, 2012, and 2013, periods associated with lower competitive index values. ACR Jobs Board activity, measured by job posting clicks, was significantly higher in 2012 than in 2011 (P Jobs Board, there were consistently more new job seekers than job postings throughout the study period, and fall is the period in the year most associated with the highest competitive index for radiologist employment.

Lack of AcrB Efflux Function Confers Loss of Virulence on Salmonella enterica Serovar Typhimurium

Directory of Open Access Journals (Sweden)

Xuan Wang-Kan

2017-07-01

Full Text Available AcrAB-TolC is the paradigm resistance-nodulation-division (RND multidrug resistance efflux system in Gram-negative bacteria, with AcrB being the pump protein in this complex. We constructed a nonfunctional AcrB mutant by replacing D408, a highly conserved residue essential for proton translocation. Western blotting confirmed that the AcrB D408A mutant had the same native level of expression of AcrB as the parental strain. The mutant had no growth deficiencies in rich or minimal medium. However, compared with wild-type SL1344, the mutant had increased accumulation of Hoechst 33342 dye and decreased efflux of ethidium bromide and was multidrug hypersusceptible. The D408A mutant was attenuated in vivo in mouse and Galleria mellonella models and showed significantly reduced invasion into intestinal epithelial cells and macrophages in vitro. A dose-dependent inhibition of invasion was also observed when two different efflux pump inhibitors were added to the wild-type strain during infection of epithelial cells. RNA sequencing (RNA-seq revealed downregulation of bacterial factors necessary for infection, including those in the Salmonella pathogenicity islands 1, 2, and 4; quorum sensing genes; and phoPQ. Several general stress response genes were upregulated, probably due to retention of noxious molecules inside the bacterium. Unlike loss of AcrB protein, loss of efflux function did not induce overexpression of other RND efflux pumps. Our data suggest that gene deletion mutants are unsuitable for studying membrane transporters and, importantly, that inhibitors of AcrB efflux function will not induce expression of other RND pumps.

Substrate binding accelerates the conformational transitions and substrate dissociation in multidrug efflux transporter AcrB

Directory of Open Access Journals (Sweden)

Beibei eWang

2015-04-01

Full Text Available The tripartite efflux pump assembly AcrAB-TolC is the major multidrug resistance transporter in E. coli. The inner membrane transporter AcrB is a homotrimer, energized by the proton movement down the transmembrane electrochemical gradient. The asymmetric crystal structures of AcrB with three monomers in distinct conformational states (access (A, binding (B and extrusion (E support a functional rotating mechanism, in which each monomer of AcrB cycles among the three states in a concerted way. However, the relationship between the conformational changes during functional rotation and drug translocation has not been totally understood. Here, we explored the conformational changes of the AcrB homotrimer during the ABE→BEA transition in different substrate-binding states using targeted MD simulations. It was found that the dissociation of substrate from the distal binding pocket of B monomer is closely related to the concerted conformational changes in the translocation pathway, especially the side chain reorientation of Phe628 and Tyr327. A second substrate binding at the proximal binding pocket of A monomer evidently accelerates the conformational transitions as well as substrate dissociation in B monomer. The acceleration effect of the multi-substrate binding mode provides a molecular explanation for the positive cooperativity observed in the kinetic studies of substrate efflux and deepens our understanding of the functional rotating mechanism of AcrB.

To describe retinal diseases found in patients who were waiting for treatment at a tertiary care hospital in Rio Branco, Acre, Brazil. Patients underwent slit lamp biomicroscopy, dilated fundus exam and ocular ultrasound. Patients were classified according to phakic status and retinal disease of the most severely affected eye. A total of 138 patients were examined. The mean age was 51.3 years. Diabetes was present in 35.3% and hypertension in 45.4% of these patients. Cataract was found in 23.2% of patients, in at least one eye. Retinal examination was possible in 129 patients. The main retinal diseases identified were rhegmatogenous retinal detachment (n=23; 17.8%) and diabetic retinopathy (n=32; 24.8%). Out of 40 patients evaluated due to diabetes, 13 (32.5%) had absent or mild forms of diabetic retinopathy and did not need further treatment, only observation. Diabetic retinopathy was the main retinal disease in this population. It is an avoidable cause of blindness and can be remotely evaluated, in its initial stages, by telemedicine strategies. In remote Brazilian areas, telemedicine may be an important tool for retinal diseases diagnosis and follow-up.

Lopes de Oliveira, R.; Janot-Pacheco, E.

2003-08-01

Alguns fenômenos de outbursts em Be-X sugerem a existência, mesmo que temporária, de um disco de acresção quando da passagem do objeto compacto pelo periastro orbital. Neste trabalho avaliamos a possibilidade de formação do disco de acresção em sistemas Be+estrela de neutrons e Be+anã branca, e a influência da excentricidade orbital na ocorrência deste fenômeno. Utilizamos a expressão analítica para o momento angular específico da matéria constituinte de um meio em expansão lenta, como é o caso do disco circunstelar das estrelas Be, proposta por Wang(1981), sob a condição básica de que o raio de circularização deva ser maior do que o raio de Alfvén. Concluímos que existe um limite para o período orbital do sistema acima do qual não é possível a formação do disco de acresção, e que este valor aumenta para sistemas com excentricidade orbital maior.

Arsenic (As) pollution is a global problem, and the plant-based cleanup of contaminated soils, called phytoremediation, is therefore of great interest. Recently, transgenic approaches have been designed to develop As phytoremediation technologies. Here, we used a one-gene transgenic approach for As tolerance and accumulation in Arabidopsis thaliana . PvACR3, a key arsenite [As(III)] antiporter in the As hyperaccumulator fern Pteris vittata , was expressed in Arabidopsis , driven by the CaMV 35S promoter. In response to As treatment, PvACR3 transgenic plants showed greatly enhanced tolerance. PvACR3 transgenic seeds could even germinate and grow in the presence of 80 μM As(III) or 1200 μM arsenate [As(V)] treatments that were lethal to wild-type seeds. PvACR3 localizes to the plasma membrane in Arabidopsis and increases arsenite efflux into external medium in short-term experiments. Arsenic determination showed that PvACR3 substantially reduced As concentrations in roots and simultaneously increased shoot As under 150 μM As(V). When cultivated in As(V)-containing soil (10 ppm As), transgenic plants accumulated approximately 7.5-fold more As in above-ground tissues than wild-type plants. This study provides important insights into the behavior of PvACR3 and the physiology of As metabolism in plants. Our work also provides a simple and practical PvACR3 transgenic approach for engineering As-tolerant and -hyperaccumulating plants for phytoremediation.

CANDU (Canadian Deuterium Uranium) is a type of reactor that uses heavy water (D{sub 2}O) as a moderator and as a refrigerant. Despite having chemical characteristics similar to light water (H{sub 2}O), heavy water has a high moderation ratio for neutrons. This feature enables CANDU to use natural uranium as fuel. However, research has evaluated the possibility of using H{sub 2}O as a refrigerant and D{sub 2}O as a moderator aiming at reducing the volume of heavy water. Such changes would imply the use of lightly enriched uranium due to the presence of H{sub 2}O. In this context, the concept of ACR (Advanced CANDU Reactor) has been developed. This reactor has an innovative design which combines of the current CANDU with the characteristics of PWR (Pressurized Water Reactor) type reactors. Studies by AECL (Atomic Energy Canada Limited) show that compared to CANDU, the ACR presents a cost reduction in construction, improved firing performance, improved operation safety and longer life. The present work aims to evaluate, in steady state, some of the main neutron parameters of CANDU-6 and ACR-1000. The MCNPX 2.6.0 code (Monte Carlo N-Particle eXtended -version 2.6.0) was used to simulate such types of reactors. The results show that the models configured in the MCNPX adequately reproduce the neutron behavior of the studied reactors. These models may be used in future work for analysis of fuel burn and evolution.

New reactor designs require the evaluation of design alternatives to reduce the radiological risk by preventing severe accidents or by limiting releases from the plant in the event of such accidents. The Advanced CANDU Reactor TM (ACR TM ) design has provisions to prevent and mitigate severe accidents. This paper describes key ACR design features for severe accident mitigation. It provides a high-level overview of the findings to date. Several design provisions have not yet been finalized or decided, but the designers are keenly aware of the SAM concepts and their requirements. The active heat sinks for 'vessels' (i.e., the fuel channels, the calandria vessel, the calandria end-shields and the calandria vault) are all amply capable of dissipating the severe accident heat loads. These heat sinks are designed to be operable under severe accident environmental conditions; however, their operability is yet to be confirmed by assessments. The active heat sinks for the various process vessels are 'backed up' by passive heat sinks (i.e., steaming plus water make-up from the RWS). The supply side of passive heat sinks is simple, rugged, and not vulnerable to failures of plant systems. The importance of the steam relief side is recognized, and the adequate relief capacity will be provided. The passive heat sinks will give the SAM more than 1 day (likely several days) to diagnose the accident and to establish the ultimate heat sinks. The spray system for containment pressure suppression is designed for high reliability and has ample capacity to ensure low containment leakage without external intervention, after which time alternative supply to the sprays can be brought on line manually. The sprays are backed up by the LACs which are assessed for operability following a severe accident. The strong ACR containment will provide a long time of completely passive protection for any severe accident at decay power. Its characteristics are not prone to catastrophic failures. The

Antimicrobial resistance of human pathogenic bacteria is an emerging problem for global public health. This resistance is often associated with the overproduction of membrane transport proteins that are capable to pump chemotherapeutics, antibiotics, detergents, dyes and organic solvents out of the cell. In Gram-negative bacteria such as Escherichia coli and Pseudomonas aeruginosa, tripartite multidrug efflux systems extrude a large variety of cytotoxic substances from the cell membrane directly into the medium bypassing the periplasm and the outer membrane. In E. coli, the tripartite efflux system AcrA/AcrB/TolC is the pump in charge of the efflux of multiple antibiotics, dyes, bile salts and detergents. The trimeric outer membrane factor (OMF) TolC forms a beta-barrel pore in the outer membrane and exhibits a long periplasmic alpha-helical conduit. The periplasmic membrane fusion protein (MFP) AcrA serves as a linker between TolC and the trimeric resistance nodulation cell division (RND) pump AcrB, located in the inner membrane acting as a proton/drug antiporter. The newly elucidated asymmetric structure of trimeric AcrB reveals three different monomer conformations representing consecutive states in a transport cycle. The monomers show tunnels with occlusions at different sites leading from the lateral side through the periplasmic porter (pore) domains towards the funnel of the trimer and TolC. The structural changes create a hydrophobic pocket in one monomer, which is not present in the other two monomers. Minocyclin and doxorubicin, both AcrB substrates, specifically bind to this pocket substantiating its role as drug binding pocket. The energy transduction from the proton motive force into drug efflux includes proton binding in (and release from) the transmembrane part. The conformational changes observed within a triad of essential, titratable residues (Asp407/Asp408/Lys940) residing in the hydrophobic transmembrane domain appear to be transduced by

AcrA suppressor alterations reverse the drug hypersensitivity phenotype of a TolC mutant by inducing TolC aperture opening

Summary In Escherichia coli, the TolC–AcrAB complex forms a major antibiotic efflux system with broad substrate specificity. During the complex assembly, the periplasmic helices and bottom turns of TolC are thought to interact with a hairpin helix of AcrA and hairpin loops of AcrB respectively. In the present study we show that a four-residue substitution in TolC’s turn 1, which connects outer helices 3 and 4 proximal to TolC’s periplasmic aperture, confers antibiotic hypersensitivity without affecting TolC-mediated phage or colicin infection. However, despite the null-like drug sensitivity phenotype, chemical cross-linking analysis revealed no apparent defects in the ability of the mutant TolC protein to physically interact with AcrA and AcrB. A role for TolC turn 1 residues in the functional assembly of the tripartite efflux pump complex was uncovered through isolating suppressor mutations of the mutant TolC protein that mapped within acrA and by utilizing a labile AcrA protein. The data showed that AcrA-mediated suppression of antibiotic sensitivity was achieved by dilating the TolC aperture/channel in an AcrB-dependent manner. The results underscore the importance of the periplasmic turn 1 of TolC in the functional assembly of the tripartite efflux complex and AcrA in transitioning TolC from its closed to open state.

The geochemical prospecting conducted for phosphates in Acre which could explain the good fertility of the region was charged to discover this material. The phosphates are strictly built of all the bone structures and coprolites of the several fragments of vertebrate fossils, which are widespread in the region. The phosphatic fossils are bedded in the Solimoes Formation, especially its basal to intermediary conglomeratic bed. The fossils are constituted of low crystallinity apatite, and their matrix sediments include quartz, feldspars, smectite, halloysite and calcite. The P 2 O 5 content reaches up to 5% in the sediments and up to 32% in the fragments. The fossils are enriched in U 3 O 8 and rare earth elements. There is no perspect of classic or mineral deposits but the geological knowlwdge will permit the improvement of the use of the soils in Acre. (author) [pt

Leaching Studies on ACR-1000{sup R} Fuel Under Reactor Operating Conditions

Energy Technology Data Exchange (ETDEWEB)

Sunder, S. [Atomic Energy of Canada Limited, Fuel and Fuel Channel Safety Branch, Chalk River, Ontario, K0J 1J0 (Canada)

ACR-1000{sup R} is the latest nuclear power reactor being developed by AECL. The ACR-1000 fuel uses a modified CANFLEX{sup R} fuel bundle that contains low-enriched uranium and pellets of burnable neutron absorbers (BNA) in a central element. Dysprosium and gadolinium are used as the burnable neutron absorbers and are present as oxides in a 'fully-stabilized' zirconia matrix. The BNA material in the centre element is designed to limit the coolant void reactivity of the reactor core during postulated loss-of-coolant accidents. As part of the ACR-1000 fuel development, the stability of the BNA material under conditions associated with defects of the Zircaloy sheathing of the BNA central element has been investigated. The results of these tests can be used to demonstrate the phase stability and leaching behaviour of the ACR-1000 fuel under reactor operating conditions. The samples were disks, about 3-4 mm thick, obtained from BNA pellets and Candu fuel (natural uranium UO{sub 2}) pellets (the UO{sub 2} measurements provide a reference point). Leaching tests were carried out in light water at 325 deg. C, above the maximum coolant temperature in an ACR-1000 fuel channel during normal operating conditions (319 deg. C). This temperature also bounds the maximum operating temperature for the current Candu reactors (311 deg. C). The initial pH of the solution (measured at room temperature) used in the leaching tests was 10.3. The leach rates were determined by monitoring the amount of metals leached into solutions. Leaching tests were also carried out with BNA pellet samples in the presence of Zr-2.5%Nb pressure tube coupons to determine the effects, if any, of the presence of pressure tube material on leach rates. Other leaching tests with BNA pellet samples and UO{sub 2} pellets were conducted at 80 deg. C to study the effects of temperature on the leach rates. The temperature of 80 deg. C was selected as representative of typical shutdown temperatures

2006-01-01

The purpose of this paper is to present the Plant Life Management (PLiM) strategy for the concrete containment structure of the ACR-1000 (Advanced CANDU Reactor) designed by AECL. The ACR-1000 is designed for 100-year plant life including 60-year operating life and additional 40-year decommissioning period of time. The approach adopted for the PLiM strategy of the concrete containment structure is a preventive one, key areas being: 1) design methodology, 2) material performance and 3) life cycle management and ageing management program. In the design phase, in addition to strength and serviceability, durability is a major requirement during the service life and decommissioning phase of the ACR structure. Parameters affecting durability design include: a) concrete performance, b) structural application, and c) environmental conditions. Due to the complex nature of the environmental effects acting on structures during the service life of project, it is considered that true improved performance during the service life can be achieved by improving the material characteristics. Many recent innovations in advanced concrete materials technology have made it possible to produce modern concrete such as high-performance concrete with exceptional performance characteristics. In this paper, the PLiM strategy for the ACR-1000 concrete containment is presented. In addition to addressing the design methodology and material performance areas, a systematic approach for ageing management program for the concrete containment structure is presented. (author)

Full Text Available The ACRE (ACtive REhabilitation robotic device is developed to enhance therapeutic treatment of upper limbs after stroke. The aim of this study is to assess effects and costs of ACRE training for frail elderly patients and to establish if ACRE can be a valuable addition to standard therapy in nursing home rehabilitation. The study was designed as randomized controlled trial, one group receiving therapy as usual and the other receiving additional ACRE training. Changes in motor abilities, stroke impact, quality of life and emotional well-being were assessed. In total, 24 patients were included. In this small number no significant effects of the ACRE training were found. A large number of 136 patients were excluded. Main reasons for exclusion were lack of physiological or cognitive abilities. Further improvement of the ACRE can best be focused on making the system suitable for self-training and development of training software for activities of daily living.

Keynote Address: ACR-NEMA standards and their implications for teleradiology

Science.gov (United States)

Horii, Steven C.

1990-06-01

The ACR-NEMA Standard was developed initially as an interface standard for the interconnection of two pieces of imaging equipment Essentially the Standard defmes a point-to-point hardware connection with the necessary protocol and data structure so that two differing devices which meet the specification will be able to communicate with each other. The Standard does not defme a particular PACS architecture nor does it specify a database structure. In part these are the reasons why implementers have had difficulty in using the Standard in a full PACS. Recent activity of the Working Groups formed by the Committee overseeing work on the ACR-NEMA Standard has changed some of the " flavor" of the Standard. It was realized that connection of PACS with hospital and radiology information systems (HIS and RIS) is necessary if a PACS is ever to be succesful. The idea of interconnecting heterogeneous computer systems has pushed Standards development beyond the scope of the original work. Teleradiology which inherenfly involves wide-area networking may be a direct beneficiary of the new directions taken by the Standards Working Groups. This paper will give a brief history of the ACR-NEMA effort describe the " parent" Standard and its " offspring" and describe the activity of the current Working Groups with particular emphasis on the potential impacts on teleradiology.

2009-01-01

The Ageing of reinforced concrete structures due to service conditions, aggressive environments, or accidents may cause their strength, serviceability and durability to decrease over time. For a new plant, a Plant Life Management (PLiM) program should start in the design process and then continues through the plant operation and decommissioning. Hence, PLiM must provide not only Ageing Management program (AMP) but also provide requirements on material characteristic and design criteria as well. The purpose of this paper is to present the Plant Life Management (PLiM) strategy for the concrete containment structure of the ACR-10001 (Advanced CANDU Reactor) designed by AECL. The ACR-1000 is designed for a 100-year plant life including 60-year operating life and an additional 40-year decommissioning period. The approach adopted for the PLiM strategy of the concrete containment structure is a preventive one, key areas being: 1) design methodology, 2) material performance and 3) ageing management program. During the design phase, in addition to strength and serviceability, durability, throughout the service life and decommissioning phase of the ACR-1000 structure, is a major consideration. Factors affecting durability design include: a) concrete performance, b) structural application, and c) consideration of environmental conditions. In addition to addressing the design methodology and material performance requirements, a systematic approach for the ageing management program for the concrete containment structure is presented.

Full Text Available AcrAB-TolC and their homologs are major multidrug efflux systems in Gram-negative bacteria. The inner membrane component AcrB functions as a trimer. Replacement of Pro223 by Gly in AcrB decreases the trimer stability and drastically reduces the drug efflux activity. The goal of this study is to identify suppressor mutations that restore function to mutant AcrBP223G and explore the mechanism of function recovery. Two methods were used to introduce random mutations into the plasmid of AcrBP223G. Mutants with elevated drug efflux activity were identified, purified, and characterized to examine their expression level, trimer stability, interaction with AcrA, and substrate binding. Nine single-site repressor mutations were identified, including T199M, D256N, A209V, G257V, M662I, Q737L, D788K, P800S, and E810K. Except for M662I, all other mutations located in the docking region of the periplasmic domain. While three mutations, T199M, A209V, and D256N, significantly increased the trimer stability, none of them restored the trimer affinity to the wild type level. M662, the only site of mutation that located in the porter domain, was involved in substrate binding. Our results suggest that the function loss resulted from compromised AcrB trimerization could be restored through various mechanisms involving the compensation of trimer stability and substrate binding.

The Advanced CANDU Reactor or the ACR-1000 is developed by Atomic Energy of Canada Limited (AECL) to be the next step in the evolution of the CANDU product line. It is based on the proven CANDU technology and incorporates advanced design technologies. The ACR containment structure is an essential element of the overall defense in depth approach to reactor safety, and is a physical barrier against the release of radioactive material to the environment. Therefore, it is important to provide a robust design with an adequate margin of safety. One of the key design requirements of the ACR containment structure is to have an ultimate pressure capacity that is at least twice the design pressure Using standard design codes, the containment structure is expected to behave elastically at least up to 1.5 times the design pressure. Beyond this pressure level, the concrete containment structure with reinforcements and post-tension tendons behaves in a highly non-linear manner and exhibits a complex response when cracks initiate and propagate. To predict the structural non-linear responses, at least two critical features are involved. These are: the structural idealization by the geometry and material property models, and the adopted solution algorithm. Therefore, detailed idealization of the concrete structure is needed in order to accurately predict its ultimate pressure capacity. This paper summarizes the analysis methodology to be carried out to establish the ultimate pressure capacity of the ACR containment structure and to confirm that the structure meets the specified design requirements.

The presence of the highly toxic furfural and hydroxymethylfurfural (HMF) in the hydrolysate of lignocellulosic biomass prompted the investigation of the Escherichia coli ΔacrR regulatory mutant for higher tolerance to these compounds, to facilitate the production of biofuels and biochemicals, and further biocatalytic conversions. In comparison with the parental strain, the regulatory mutant with the upregulated efflux pump AcrAB-TolC produced moderately better growth and higher tolerance to concentrations of furfural and HMF between 1 and 2 g L(-1) . © 2014 International Union of Biochemistry and Molecular Biology, Inc.

Response to arsenic stress in Saccharomyces cerevisiae is orchestrated by the regulatory protein Yap8, which mediates transcriptional activation of ACR2 and ACR3. This study contributes to the state of art knowledge of the molecular mechanisms underlying yeast stress response to arsenate as it provides the genetic and biochemical evidences that Yap8, through cysteine residues 132, 137, and 274, is the sensor of presence of arsenate in the cytosol. Moreover, it is here reported for the first time the essential role of the Mediator complex in the transcriptional activation of ACR2 by Yap8. Based on our data, we propose an order-of-function map to recapitulate the sequence of events taking place in cells injured with arsenate. Modification of the sulfhydryl state of these cysteines converts Yap8 in its activated form, triggering the recruitment of the Mediator complex to the ACR2/ACR3 promoter, through the interaction with the tail subunit Med2. The Mediator complex then transfers the regulatory signals conveyed by Yap8 to the core transcriptional machinery, which culminates with TBP occupancy, ACR2 upregulation and cell adaptation to arsenate stress. Additional co-factors are required for the transcriptional activation of ACR2 by Yap8, particularly the nucleosome remodeling activity of SWI/SNF and SAGA complexes. Copyright © 2017.

Full Text Available Os empregadores, em razão de sua posição no binômio capital-trabalho, ocupariam provavelmente estratos de remuneração mais alta. No entanto, há desníveis de rendimentos, como ocorre entre trabalhadores brancos e negros, em que estes se tornam empregadores preponderantemente em setores menos privilegiados e ocupações com alto índice de informalidade, em pequenos empreendimentos com menor estabilidade. Este artigo a apresenta um breve perfil de empregadores negros e brancos no Brasil; b demonstra as desigualdades de inserção na estrutura do mercado de trabalho e c mensura os diferenciais médios de renda a fim de determinar o peso de fatores produtivos e da discriminação racial sobre a renda média dos empregadores estratificados por raça e sexo. Com base na análise quantitativa, empregando o método de decomposição de Oaxaca-Blinder, sustenta-se que existe uma diferença significativa de rendimentos entre estratos orientados por raça e sexo de empregadores que não pode ser creditada unicamente a fatores associados, como nível de escolaridade, experiência ou diferentes inserções ocupacionais, mas provém de um resíduo não explicado que é atribuído à discriminação de raça ou sexo

A Crítica de Otto Klineberg aos testes de inteligência. O Brasil como laboratório racial

Directory of Open Access Journals (Sweden)

Marcos Chor Maio

Full Text Available Resumo Otto Klineberg, professor de psicologia social na Universidade de Columbia, assegurou que os testes de inteligência eram uma ferramenta para legitimar hierarquias raciais. Ele conduziu numerosos estudos sobre as relações entre negros, brancos, índios e grupos de imigrantes nos Estados Unidos e na Europa na qual ressaltou que os aspectos ambientais superavam os fatores raciais. Klineberg concebia o Brasil como um ambiente privilegiado para demonstrar que os testes de inteligência não tinham qualquer base científica. O presente artigo tem um foco triplo: três estudos realizados por Klineberg entre 1927 e 1935; suas experiências no Brasil de 1945 a 1947 como professor da Universidade de São Paulo, quando ele tentou investigar a relação entre testes de inteligência e condições socioeconômicas em escolas do Rio de Janeiro; e sua atuação inicial na Unesco, após a 2a Guerra Mundial, quando muitos ainda estavam convencidos que os testes de inteligência eram uma forma adequada para medir as chamadas habilidades inatas.

Computational Study of Correlated Domain Motions in the AcrB Efflux Transporter

Directory of Open Access Journals (Sweden)

Robert Schulz

2015-01-01

Full Text Available As active part of the major efflux system in E. coli bacteria, AcrB is responsible for the uptake and pumping of toxic substrates from the periplasm toward the extracellular space. In combination with the channel protein TolC and membrane fusion protein AcrA, this efflux pump is able to help the bacterium to survive different kinds of noxious compounds. With the present study we intend to enhance the understanding of the interactions between the domains and monomers, for example, the transduction of mechanical energy from the transmembrane domain into the porter domain, correlated motions of different subdomains within monomers, and cooperative effects between monomers. To this end, targeted molecular dynamics simulations have been employed either steering the whole protein complex or specific parts thereof. By forcing only parts of the complex towards specific conformational states, the risk for transient artificial conformations during the simulations is reduced. Distinct cooperative effects between the monomers in AcrB have been observed. Possible allosteric couplings have been identified providing microscopic insights that might be exploited to design more efficient inhibitors of efflux systems.

The Candu (Canada Deuterium Uranium) and ACR (Advanced Candu Reactor) are pressure tubes (PT) heavy water moderated reactors. Candu are heavy water and ACR are light water cooled reactors. The pressure tube is filled with 12 bundles, each consisting of 37 respectively 43 fuel rods. One Candu reactor is in operation at Cernavoda, Romania since 1996. ACR is a proposed advanced Candu. PT diameter variation has a significant impact on the thermal-hydraulic parameters. Almost all thermal-hydraulic parameters change, but some of them have a greater significance. In this work we have considered a set of radial and axial PT diameter variations both for Candu-600 and ACR-700 reactors using various types of fuel bundles. We can conclude the following: 1) some thermal-hydraulic parameters are significantly influenced: critical heat flux (CHF), pressure drop, or void fraction; 2) the most significant parameter CHF is worsening which reduces the safety margin; 3) some fuel types present a better thermal-hydraulic behavior; and 4) fuel bundles with fresh fuel or low burnup have a worse thermal-hydraulic behaviour than those at average burn-up.

In this study, the relative quantification of acrB, soxS, marA and ramA genes expression was evaluated in 14 strains of S. enterica, with or without accompanying mutations in the quinolone resistance-determining regions of the gyrA gene, that were exposed to ciprofloxacin during the exponential growth phase. The presence of ciprofloxacin during the log phase of bacterial growth activated the genes marA, soxS, ramA and acrB in all S. enterica strains analyzed in this study. The highest expression levels for acrB were observed in strains with gyrA mutation, and marA showed the highest expression in the strains without mutation. Considering only the strains with ciprofloxacin minimum inhibitory concentration values 0.125 [1]g/mL (low susceptibility, with and without mutations in gyrA, the most expressed gene was marA. In this study, we observed that strains resistant to nalidixic acid may express genes associated with the efflux pump and the expression of the AcrAB-TolC pump genes seems to occur independently of mutations in gyrA.

To achieve the switch from conventional analog-based design to digital design in ACRs, a large number of manual operating controls and switches have to be replaced by a few common multi-function devices which is called soft control system. The soft controls in APR-1400 ACRs are classified into safety-grade and non-safety-grade soft controls; each was designed using different and independent input devices in ACRs. The operations using soft controls require operators to perform new tasks which were not necessary in conventional controls such as navigating computerized displays to monitor plant information and control devices. These kinds of computerized displays and soft controls may make operations more convenient but they might cause new types of human error. In this study the human error mechanism during the soft controls is studied and modeled to be used for analysis and enhancement of human performance (or human errors) during NPP operation. The developed model would contribute to a lot of applications to improve human performance (or reduce human errors), HMI designs, and operators' training program in ACRs. The developed model of human error mechanism for the soft control is based on assumptions that a human operator has certain amount of capacity in cognitive resources and if resources required by operating tasks are greater than resources invested by the operator, human error (or poor human performance) is likely to occur (especially in 'slip'); good HMI (Human-machine Interface) design decreases the required resources; operator's skillfulness decreases the required resources; and high vigilance increases the invested resources.

Human mobility, presence and passive transportation of Aedes aegypti mosquito, and environmental characteristics are a group of factors which contribute to the success of dengue spread and establishment. To understand this process, we assess data from dengue national and municipal basins regarding population and demographics, transportation network, human mobility, and Ae. aegypti monitoring for the Brazilian state of Acre since the first recorded dengue case in the year 2000 to the year 2015. During this period, several changes in Acre's transport infrastructure and urbanization have been started. To reconstruct the process of dengue introduction in Acre, we propose an analytic framework based on concepts used in malaria literature, namely vulnerability and receptivity, to inform risk assessments in dengue-free regions as well as network theory concepts for disease invasion and propagation. We calculate the probability of dengue importation to Acre from other Brazilian states, the evolution of dengue spread between Acrean municipalities and dengue establishment in the state. Our findings suggest that the landscape changes associated with human mobility have created favorable conditions for the establishment of dengue virus transmission in Acre. The revitalization of its major roads, as well as the increased accessibility by air to and within the state, have increased dengue vulnerability. Unplanned urbanization and population growth, as observed in Acre during the period of study, contribute to ideal conditions for Ae. aegypti mosquito establishment, increase the difficulty in mosquito control and consequently its local receptivity.

The aim of this study is to investigate the reliability and validity of the Japanese version of the modified American College of Rheumatology (ACR) Preliminary Diagnostic Criteria for Fibromyalgia (mACR 2010-J) and the Fibromyalgia Symptom Scale (mFS-J). According to the ACR 1990 classification criteria, patients with chronic pain were divided into the fibromyalgia group and nonfibromyalgia group (rheumatoid arthritis and osteoarthritis). Patients in both groups were assessed using mACR 2010-J and mFS-J. 294 of 462 (64 %) patients in the fibromyalgia group met mACR 2010-J, whereas 4 % (9/231) of the nonfibromyalgia group did, with sensitivity of 64 %, specificity of 96 %, positive predictive value of 97 %, negative predictive value of 56 %, and positive likelihood ratio of 16.3. Mean total scores on mFS-J significantly differentiated the fibromyalgia from the nonfibromyalgia group. According to the value of the Youden index, the best cutoff score for the mFS-J was 9/10. Our findings indicate that mACR 2010-J as a positive test and mFS-J as a quantification scale might be suitable for assessing fibromyalgia among Japanese chronic pain populations.

Microbial arsenite (AsIII) oxidation forms a critical piece of the arsenic cycle in nature, though our understanding of how and why microorganisms oxidize AsIII remains rudimentary. Our model organism Agrobacterium tumefaciens 5A contains two distinct ars operons (ars1 and ars2) that are similar in their coding region content. The ars1 operon is located nearby the aio operon that is essential for AsIII oxidation. The AsIII/H(+) anti-porters encoded by acr3-1 and acr3-2 are required for maximal AsIII and antimonite (SbIII) resistance, but acr3-1 (negatively regulated by ArsR-1) appears more active in this regard and also required for AsIII oxidation and expression of aioBA. A malate-phosphate anti-porter DctA is regulated by RpoN and AsIII, and is required for normal growth with malate as a sole carbon source. Qualitatively, a ΔdctA mutant was normal for AsIII oxidation and AsIII/SbIII resistance at metalloid concentrations inhibitory to the Δacr3-1 mutant; however, aioBA induction kinetics was significantly phase-shift delayed. Acr3 involvement in AsIII/SbIII resistance is reasonably well understood, but the role of Acr3 and DctA anti-porters in AsIII oxidation and its regulation is unexpected, and suggests that controlled AsIII trafficking across the cytoplasmic membrane is important to a process understood to occur in the periplasm. © 2014 Society for Applied Microbiology and John Wiley & Sons Ltd.

Multidrug transcription regulator AcrR from Salmonella enterica subsp. enterica serovar Typhimurium str. LT2 belongs to the tetracycline repressor family, one of the largest groups of bacterial transcription factors. The crystal structure of dimeric AcrR was determined and refined to 1.56 Å resolution. The tertiary and quaternary structures of AcrR are similar to those of its homologs. The multidrug binding site was identified based on structural alignment with homologous proteins and has a di(hydroxyethyl)ether molecule bound. Residues from helices a4 and a7 shape the entry into this binding site. The structure of AcrR reveals that the extended helical conformation of helix a4 is stabilized by the hydrogen bond between Glu67 (helix a4) and Gln130 (helix a7). Based on the structural comparison with the closest homolog structure, the Escherichia coli AcrR, we propose that this hydrogen bond is responsible for control of the loop-to-helix transition within helix a4. This local conformational switch of helix a4 may be a key step in accessing the multidrug binding site and securing ligands at the binding site. Solution smallmolecule binding studies suggest that AcrR binds ligands with their core chemical structure resembling the tetracyclic ring of cholesterol.

InfAcrOnt: calculating cross-ontology term similarities using information flow by a random walk.

Since the establishment of the first biomedical ontology Gene Ontology (GO), the number of biomedical ontology has increased dramatically. Nowadays over 300 ontologies have been built including extensively used Disease Ontology (DO) and Human Phenotype Ontology (HPO). Because of the advantage of identifying novel relationships between terms, calculating similarity between ontology terms is one of the major tasks in this research area. Though similarities between terms within each ontology have been studied with in silico methods, term similarities across different ontologies were not investigated as deeply. The latest method took advantage of gene functional interaction network (GFIN) to explore such inter-ontology similarities of terms. However, it only used gene interactions and failed to make full use of the connectivity among gene nodes of the network. In addition, all existent methods are particularly designed for GO and their performances on the extended ontology community remain unknown. We proposed a method InfAcrOnt to infer similarities between terms across ontologies utilizing the entire GFIN. InfAcrOnt builds a term-gene-gene network which comprised ontology annotations and GFIN, and acquires similarities between terms across ontologies through modeling the information flow within the network by random walk. In our benchmark experiments on sub-ontologies of GO, InfAcrOnt achieves a high average area under the receiver operating characteristic curve (AUC) (0.9322 and 0.9309) and low standard deviations (1.8746e-6 and 3.0977e-6) in both human and yeast benchmark datasets exhibiting superior performance. Meanwhile, comparisons of InfAcrOnt results and prior knowledge on pair-wise DO-HPO terms and pair-wise DO-GO terms show high correlations. The experiment results show that InfAcrOnt significantly improves the performance of inferring similarities between terms across ontologies in benchmark set.

To investigate what factors influence patient global health assessment (PtGlobal), and how those factors and the reliability of PtGlobal affect the rate, reliability, and validity of recently published American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) rheumatoid arthritis (RA) remission criteria when used in clinical practice. We examined consecutive patients with RA in clinical practice and identified 77 who met ACR/EULAR joint criteria for remission (≤ 1 swollen joint and ≤ 1 tender joint). We evaluated factors associated with a PtGlobal > 1, because a PtGlobal ≤ 1 defined ACR/EULAR remission in this group of patients who had already met ACR/EULAR joint criteria. Of the 77 patients examined, only 17 (22.1%) had PtGlobal ≤ 1 and thus fully satisfied ACR/EULAR criteria. A large proportion of patients not in remission by ACR/EULAR criteria had high PtGlobal related to noninflammatory issues, including low back pain, fatigue, and functional limitations, and a number of patients clustered in the range of PtGlobal > 1 and ≤ 2. However, the minimal detectable difference for PtGlobal was 2.3. In addition, compared with a PtGlobal severity score, a PtGlobal activity score was 3.3% less likely to be abnormal (> 1). Noninflammatory factors contribute to the level of PtGlobal and result in the exclusion of many patients who would otherwise be in "true" remission according to the ACR/EULAR definition. Reliability problems associated with PtGlobal can also result in misclassification, and may explain the observation of low longterm remission rates in RA. As currently constituted, the use of the ACR/EULAR remission criteria in clinical practice appears to be problematic.

Combating obsolescence - ACR digital control systems design

International Nuclear Information System (INIS)

Tikku, S.; Raiskums, G.

2006-01-01

The ever increasing use of digital technologies and products to meet the control, automation and monitoring needs of the nuclear power plant - even though justified by the benefits it provides - comes with an increased risk of technological obsolescence happening through the course of the plant life. Some well considered strategies are being employed in the ACR design process to minimise this risk and alleviate the consequence if it happens. These include application of a modular overall architecture, adoption of international widely accepted standards to harmonise equipment qualification and software practices, production of control functional specifications that are not influenced by target platform, and careful selection of technologies and products.

Assessment of the thermalhydraulic performance of the moderator circulation system for the Advanced CANDU Reactor (ACR) was carried out using the specialized Computational Fluid Dynamics (CFD) code MODTURC C LAS V2.9 IST. The assessment included modeling the moderator circulation inside the calandria vessel under nominal and isothermal flow conditions. The modeling results show that the moderator flow through the core is relatively uniform and mostly upward. The moderator temperature distribution is nearly stratified and increases monotonically from the bottom to the top of the calandria vessel. (author)

Full Text Available The present study aimed to investigate body adiposity and nutritional status among indigenous children from Kaxinawá Tribe by using anthropometry. The sample was composed by 93 children aged 6 to 10 years and of both sexes, living at the villages Kaxinawá do Caucho e Paroá, in the state of Acre, Brazil. Body adiposity was estimated by skinfold thickness at triceps and subscapular sites and by the sum of these two skinfolds. Nutritional status was identified by the indicators weight-for age (w/a, stature-for-age (s/a and weight-for-stature (w/s using z-score cut-off points suggested by the World Health Organization. For comparison between sexes, the Student’s t-test was used. Low body fat prevalence was observed in 83.7% of boys and 62% of girls. There were significant differences between sexes at 8 and 10 years of age for the triceps skinfolds and the sum of skinfolds. For the subscapular skinfold, the difference was observed only at 8 years of age. Chronic malnutrition was detected in both sexes and the prevalence depended upon the applied criteria. The prevalence was 76.3% for s/a and 47.3% for w/a. Acute malnutrition was present among 12.9% of children when using w/s. Boys tended to have higher prevalence for chronic malnutrition (s/a and w/a, while the girls for acute malnutrition (w/s.

Objectives The Systemic Lupus International Collaborating Clinics (SLICC) group proposed revised classification criteria for systemic lupus erythematosus (SLICC-2012 criteria). This study aimed to compare these criteria with the well-established American College of Rheumatology classification criteria (ACR-1997 criteria) in a national cohort of juvenile-onset systemic lupus erythematosus (JSLE) patients and evaluate how patients' classification criteria evolved over time. Methods Data from patients in the UK JSLE Cohort Study with a senior clinician diagnosis of probable evolving, or definite JSLE, were analyzed. Patients were assessed using both classification criteria within 1 year of diagnosis and at latest follow up (following a minimum 12-month follow-up period). Results A total of 226 patients were included. The SLICC-2012 was more sensitive than ACR-1997 at diagnosis (92.9% versus 84.1% p < 0.001) and after follow up (100% versus 92.0% p < 0.001). Most patients meeting the SLICC-2012 criteria and not the ACR-1997 met more than one additional criterion on the SLICC-2012. Conclusions The SLICC-2012 was better able to classify patients with JSLE than the ACR-1997 and did so at an earlier stage in their disease course. SLICC-2012 should be considered for classification of JSLE patients in observational studies and clinical trial eligibility.

Tumors exploit immunoregulatory checkpoints to attenuate T cell responses as a means of circumventing immunologic rejection. By activating the inhibitory costimulatory pathway of Programmed Death 1 (PD1)/PDL1 which provides tumor cells an escape mechanism from immune surveillance, Programmed Death Ligand1 (PDL1)(+) tumors hamper activated tumor-specific T cell functions and render them functionally exhausted. To overcome the inhibitory costimulatory effects of PDL1 on the adoptively transferred T cells, we sought to convert PD1 to a T cell costimulatory receptor by exchanging its transmembrane and cytoplasmic tail with CD28 and 4-1BB signaling domains (PD1-CD28-4-1BB, PD1-ACR), anticipating the genetically modified effector T lymphocytes expressing PD1-ACR would exhibit enhanced functional attributes. And the results showed that PD1-ACR expressed T cells retained the ability to bind PDL1, resulting in T cell activation as evidenced by the elevated activity of phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt), the augmentation of cytokine secretion and the increased proliferative capacity. Moreover, when systemically administered in the mouse model of glioblastoma metastases, PD1-ACR T cells localized at the area of U87 invasive tumor, which results in suppressed tumor growth and enhanced survival of mice with established U87 glioblastoma. Together, these data demonstrated that PD1-ACR has a high potential to serve as a novel strategy to overcome PDL1 mediated immunosuppression of T cells for cancer therapy.

A fundamental consideration in the workup of a jaundiced patient is the pretest probability of mechanical obstruction. Ultrasound is the first-line modality to exclude biliary tract obstruction. When mechanical obstruction is present, additional imaging with CT or MRI can clarify etiology, define level of obstruction, stage disease, and guide intervention. When mechanical obstruction is absent, additional imaging can evaluate liver parenchyma for fat and iron deposition and help direct biopsy in cases where underlying parenchymal disease or mass is found. Imaging techniques are reviewed for the following clinical scenarios: (1) the patient with painful jaundice, (2) the patient with painless jaundice, and (3) the patient with a nonmechanical cause for jaundice. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances where evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment. Copyright © 2013 American College of Radiology.

Full Text Available Os problemas ocasionados pela poluição do ar em razão das queimadas existentes dentro e fora do Estado do Acre têm causado sérios prejuízos à saúde da população. Como as queimadas provocam malefícios à sociedade, a mensuração da disposta a pagar (DAP para diminuir esses impactos, constitui importante informação para avaliar se um projeto de despoluição é viável economicamente. De forma geral, objetivou-se analisar os impactos da poluição do ar pelas queimadas sobre a sociedade acreana. Especificamente: a determinar quanto a sociedade está disposta a pagar pela diminuição dos malefícios ocasionados pelas queimadas; e b comparar o valor da disposição a pagar agregada com o custo das morbidades respiratórias no ano de 2004. A teoria das externalidades é utilizada para referenciar este trabalho. A partir de referendum with follow-up, estimou-se o valor dos benefícios da melhoria da qualidade do ar no Estado do Acre cujos resultados indicaram que cada dólar aplicado em despesas de internações ocasionadas por morbidades respiratórias à melhoria do ar acarreta um benefício de R$ 21,08, o que representa que a melhoria dessa característica ambiental é viável economicamente.

LmACR2 from L. major is the first rhodanese-like enzyme directly involved in the reduction of arsenate and antimonate to be crystallized. Diffraction data have been collected to 1.99 Å resolution using synchrotron X-rays. Arsenic is present in the biosphere owing either to the presence of pesticides and herbicides used in agricultural and industrial activities or to leaching from geological formations. The health effects of prolonged exposure to arsenic can be devastating and may lead to various forms of cancer. Antimony(V), which is chemically very similar to arsenic, is used instead in the treatment of leishmaniasis, an infection caused by the protozoan parasite Leishmania sp.; the reduction of pentavalent antimony contained in the drug Pentostam to the active trivalent form arises from the presence in the Leishmania genome of a gene, LmACR2, coding for the protein LmACR2 (14.5 kDa, 127 amino acids) that displays weak but significant sequence similarity to the catalytic domain of Cdc25 phosphatase and to rhodanese enzymes. For structural characterization, LmACR2 was overexpressed, purified to homogeneity and crystallized in a trigonal space group (P321 or P3{sub 1}21/P3{sub 2}21). The protein crystallized in two distinct trigonal crystal forms, with unit-cell parameters a = b = 111.0, c = 86.1 Å and a = b = 111.0, c = 175.6 Å, respectively. At a synchrotron beamline, the diffraction pattern extended to a resolution limit of 1.99 Å.

New insights into the structural and functional involvement of the gate loop in AcrB export activity.

Science.gov (United States)

Ababou, Abdessamad

2018-02-01

AcrB is a major multidrug exporter in Escherichia coli and other Gram-negative bacteria. Its gate loop, located between the proximal and the distal pockets, have been reported to play important role in the export of many antibiotics. This loop location, rigidity and interactions with substrates have led recent reports to suggest that AcrB export mechanism operates in a sequential manner. First the substrate binds the proximal pocket in the access monomer, then it moves to bind the distal pocket in the binding monomer and subsequently it is extruded in the extrusion monomer. Recently, we have demonstrated that the gate loop is not required for the binding of Erythromycin but the integrity of this loop is important for an efficient export of this substrate. However, here we show that the antibiotic susceptibilities of the same AcrB gate loop mutants for Doxorubicin were unaffected, suggesting that this loop is not required for its export, and we demonstrate that this substrate may use principally the tunnel-1, located between transmembranes 8 and 9, more often than previously reported. To further explain our findings, here we address the gate loop mutations effects on AcrB solution energetics (fold, stability, molecular dynamics) and on the in vivo efflux of Erythromycin and Doxorubicin. Finally, we discuss the efflux and the discrepancy between the structural and the functional experiments for Erythromycin in these gate loop mutants. Copyright © 2017 Elsevier B.V.

Full Text Available Abstract Background and Objectives: Increasing emergence of fluoroquinolone resistance among clinical isolates of Klebsiella pneumoniae  (K. pneumoniae, has limited the treatment options for treatment of infections caused by these bacteria. The aim of this study was to investigate the dissemination of genes encoding AcrAB and QepA efflux pumps among K. pneumoniae strains. Methods: This study was carried out on 117 K. pneumoniae strains isolated from patients hospitalized in selected hospitals in Tehran city, 2015-2016, Iran. Antimicrobial susceptibility tests were performed using disk diffusion method (based on CLSI guidelines and identification of acr A, acr B and qep A genes using PCR assay. Results: In this study, colistin and tigecycline had the best effect against clinical isolates of K. pneumoniae. According to PCR results, 110 (94% isolates had acrA gene and 102 (87% isolates had acrB gene, respectively. The qepA gene was not found in any of the K. pneumoniae strains. Conclusion: According to the results of the present study, dissemination of the genes encoding AcrAB efflux pumps among K. pneumoniae strains, which cause resistance to fluoroquinolones, is a matter of concern. Therefore, infection control and prevention of the spread of drug-resistant bacteria requires careful management in drug prescription and identification of resistant isolates.

Human intestinal parasites in crusader Acre: Evidence for migration with disease in the medieval period.

Mitchell, Piers D; Anastasiou, Evilena; Syon, Danny

2011-12-01

The aim of this research is to highlight the role of ancient parasites as evidence for human migration in past populations. The material analysed was soil sediment from the excavation of a medieval cesspool in the city of Acre, in Israel. Archaeological stratigraphy and radiocarbon dating of a fragment of animal bone from the cesspool confirm its use in the 13th century CE, during the crusader period. At that time Acre was located in the Frankish Kingdom of Jerusalem. Soil samples from the cesspool were analysed and eggs of the roundworm (Ascaris lumbricoides) and fish tapeworm (Diphyllobothrium latum) were identified. The fish tapeworm has only been found in the mainland Near East once before, in a latrine of the crusader Order of St. John (Knights Hospitaller). It has been absent in all earlier cesspools, latrines and coprolites so far studied in the region. In contrast to its rarity in the Levant, the fish tapeworm was common in northern Europe during the medieval period. The presence of fish tapeworm eggs in a crusader period cesspool in Acre suggests its use by crusaders or pilgrims from northern Europe who travelled to the Levant carrying these parasites in their intestines.

Full Text Available Abstract Background Route environments can positively influence people's active commuting and thereby contribute to public health. The Active Commuting Route Environment Scale (ACRES was developed to study active commuters' perceptions of their route environments. However, bicycle commuters represent a small portion of the population in many cities and thus are difficult to study using population-based material. Therefore, the aim of this study is to expand the state of knowledge concerning the criterion-related validity of the ACRES and the representativity using an advertisement-recruited sample. Furthermore, by comparing commuting route environment profiles of inner urban and suburban areas, we provide a novel basis for understanding the relationship between environment and bikeability. Methods Bicycle commuters from Greater Stockholm, Sweden, advertisement- (n = 1379 and street-recruited (n = 93, responded to the ACRES. Traffic planning and environmental experts from the Municipality of Stockholm (n = 24 responded to a modified version of the ACRES. The criterion-related validity assessments were based on whether or not differences between the inner urban and the suburban route environments, as indicated by the experts and by four existing objective measurements, were reflected by differences in perceptions of these environments. Comparisons of ratings between advertisement- and street-recruited participants were used for the assessments of representativity. Finally, ratings of inner urban and suburban route environments were used to evaluate commuting route environment profiles. Results Differences in ratings of the inner urban and suburban route environments by the advertisement-recruited participants were in accord with the existing objective measurements and corresponded reasonably well with those of the experts. Overall, there was a reasonably good correspondence between the advertisement- and street-recruited participants' ratings

Switch loop flexibility affects substrate transport of the AcrB efflux pump

International Nuclear Information System (INIS)

Muller, Reinke T.; Travers, Timothy; Cha, Hi-jea; Phillips, Joshua L.

2017-01-01

The functionally important switch-loop of the trimeric multidrug transporter AcrB separates the access and deep drug binding pockets in every protomer. This loop, comprising 11 amino acid residues, has been shown to be crucial for substrate transport, as drugs have to travel past the loop to reach the deep binding pocket and from there are transported outside the cell via the connected AcrA and TolC channels. It contains four symmetrically arranged glycine residues suggesting that flexibility is a key feature for pump activity. Upon combinatorial substitution of these glycine residues to proline, functional and structural asymmetry was observed. Proline substitutions on the PC1 proximal side completely abolished transport and reduced backbone flexibility of the switch loop, which adopted a conformation restricting the pathway towards the deep binding pocket. Here, two phenylalanine residues located adjacent to the substitution sensitive glycine residues play a role in blocking the pathway upon rigidification of the loop, since the removal of the phenyl rings from the rigid loop restores drug transport activity.

Membrane transporters of the RND superfamily confer multidrug resistance to pathogenic bacteria, and are essential for cholesterol metabolism and embryonic development in humans. We use high-resolution X-ray crystallography and computational methods to delineate the mechanism of the homotrimeric RND-type proton/drug antiporter AcrB, the active component of the major efflux system AcrAB-TolC in Escherichia coli, and one most complex and intriguing membrane transporters known to date. Analysis of wildtype AcrB and four functionally-inactive variants reveals an unprecedented mechanism that involves two remote alternating-access conformational cycles within each protomer, namely one for protons in the transmembrane region and another for drugs in the periplasmic domain, 50 Å apart. Each of these cycles entails two distinct types of collective motions of two structural repeats, coupled by flanking α-helices that project from the membrane. Moreover, we rationalize how the cross-talk among protomers across the trimerization interface might lead to a more kinetically efficient efflux system.

This document provides a summary of a review of the performance of bioinjection activities at the Building 100 Area and the 4.5 Acre Site at the Pinellas County, Florida, Site since 2010, determines how best to optimize future injection events, and identifies the approach for the bioinjection event in 2016 at (1) the 4.5 Acre Site and (2) the Essentra property at the Building 100 Area. Because this document describes the next bioinjection event at the 4.5 Acre Site, it also serves as an addendum to the Interim Remedial Action Plan for Emulsified Edible Oil Injection at the 4.5 Acre Site (DOE 2013). In addition, this document revises the injection layout and injection intervals for the Essentra property that were originally described in the Interim Corrective Measure Work Plan for Source and Plume Treatment at the Building 100 Area (DOE 2014), and is a de facto update of that document. Bioinjection consists of injection of emulsified vegetable oil (EVO) and the microorganism Dehalococcoides mccartyi (DHM; formerly known as Dehalococcoides ethenogenes) into the subsurface to enhance biodegradation of trichloroethene (TCE), dichloroethene (DCE), and vinyl chloride (VC). VC is the only contaminant that exceeds its maximum contaminant level (10 micrograms per liter onsite and 1 microgram per liter onsite) on the 4.5 Acre Site and the Essentra property. Bioinjection was conducted at the 4.5 Acre Site in 2010 and 2013. Approximately 49,900 gallons of EVO and DHM were injected at 95 injection points in February 2010, and approximately 22,900 gallons of EVO and DHM were injected at 46 injection points in July 2013. The injection locations are shown on Figure 1. The goal of bioinjection at the 4.5 Acre Site is to decrease contaminant concentrations to maximum contaminant levels along the west and southwest property boundaries (to meet risk–based corrective action requirements) and to minimize the extent of the contaminant plume in the interior of the site.

Essa experiência favoreceu a criação de vínculos econômicos, políticos e afetivos com a cultura regional e estimulou nos filhos um profundo conhecimento histórico e geográfico do Oeste mineiro. Além disso, o pai parece ter exercido uma profunda influência sobre os filhos no que diz respeito ao gosto pela política regional. O artigo desenvolve a hipótese de que todas essas experiências foram elementos presentes na formação de Mário Palmério e, mais tarde, apareceriam de modo explícito em sua literatura marcada pela descrição da natureza, do cotidiano e das intrigas políticas regionalistas. Palavras-chave: Regionalismo; Literatura regionalista; Literatura mineira; Mário Palmério; Vila dos Confins; Chapadão do Bugre.

The suitability of the storage phosphor plate system ACR 2000 RT (Eastman Kodak Corp., Rochester, MN, USA), that is destined for portal verification as well as for portal simulation imaging in radiotherapy, had to be proven by the comparison with a highly sensitive verification film. The comparison included portal verification images of different regions (head and neck, thorax, abdomen, and pelvis) irradiated with 6- and 15-MV photons and electrons. Each portal verification image was done at the storage screen and the EC film as well, using the EC-L cassettes (both: Eastman Kodak Corp., Rochester, MN, USA) for both systems. The soft-tissue and bony contrast and the brightness were evaluated and compared in a ranking of the two compared images. Different phantoms were irradiated to investigate the high- and low-contrast resolution. To account for quality assurance application, the short-time exposure of the unpacked and irradiated storage screen by green and red room lasers was also investigated. In general, the quality of the processed ACR images was slightly higher than that of the films, mostly due to cases of an insufficient exposure to the film. The storage screen was able to verify electron portals even for low electron energies with only minor photon contamination. The laser lines were sharply and clearly visible on the ACR images. The ACR system may replace the film without any noticeable decrease in image quality thereby reducing processing time and saving the costs of films and avoiding incorrect exposures.

Full Text Available O trabalho analisa o comportamento das alterações eletrocardiográficas em 150 indivíduos de cor preta, naturais da área rural do sul do Rio Grande do Sul, pareados com outros tantos brancos do mesmo sexo, idade e procedência. O grupo tinha idade entre 9 e 78 anos, com média de 39,2 e era composto de 57 homens e 93 mulheres. Com referência à sorologia, 84 eram positivos e 66 negativos para a infecção pelo Trypanosoma cruzi. A prevalência de alterações eletrocardiográficas foi significativamente maior entre os pretos, tanto soropositivos quanto soronegativos. As alterações eletrocardiográficas consideradas sugestivas de miocardiopatia chagásica, predominaram significativamente entre os positivos pretos. E mesmo entre os pretos negativos as alterações foram mais numerosas e de maior gravidade com respeito aos negativos brancos. Na opinião dos autores a maior prevalência e severidade das alterações eletrocardiográficas entre os pretos, podem ser atribuídos a vários fatores entre os quais se destacariam: a pobreza e marginalidade das pessoas de cor que implicam trabalhos mais pesados e desgastantes; habitações triatomínica; alimentação mais pobre quantitativa e qualitativamente. Outro fator negativo seriam os valores mais elevados de pressão arterial encontrados entre os pretos que, associados a possíveis influências de ordem racial, podem contribuir e/ou criar condições de patologia miocárdica.The pattern of ECG changes of 150 black individuals from rural areas of southern Rio Grande do Sul, Brazil, was compared with that of a group of 150 whites of similar age, sex and geographical residence.

In Brazil economically important coal deposits occur in the southern part of the Parana Basin, where coal seams occur in the Permian Rio Bonito Formation, with major coal development in the states of Rio Grande de Sul and Santa Catarina. The current paper presents results on sequence stratigraphic interpretation of the coal-bearing strata, and petrological and geochemical coal seam characterization from the South Santa Catarina Coalfield, Parana Basin. In terms of sequence stratigraphic interpretation the precursor mires of the Santa Catarina coal seams formed in an estuarine-barrier shoreface depositional environment, with major peat accumulation in a high stand systems tract (Pre-Bonito and Bonito seams), a lowstand systems tract (Ponta Alta seam, seam A, seam B) and a transgressive systems tract (Irapua, Barro Branco and Treviso seams). Seam thicknesses range from 1.70 to 2.39 m, but high proportions of impure coal (coaly shale and shaley coal), carbonaceous shale and partings reduce the net coal thickness significantly. Coal lithoypes are variable, with banded coal predominant in the Barro Branco seam, and banded dull and dull coal predominantly in Bonito and Irapua seams, respectively. Results from petrographic analyses indicate a vitrinite reflectance range from 0.76 to 1.63 %Rrandom (HVB A to LVB coal). Maceral group distribution varies significantly, with the Barro Branco seam having the highest vitrinite content (mean 67.5 vol%), whereas the Irapua seam has the highest inertinite content (33.8 vol%). Liptinite mean values range from 7.8 vol% (Barro Branco seam) to 22.5 vol% (Irapua seam). Results from proximate analyses indicate for the three seams high ash yields (50.2 - 64.2 wt.%). Considering the International Classification of in-Seam Coals, all samples are in fact classified as carbonaceous rocks (> 50 wt.% ash). Sulfur contents range from 3.4 to 7.7 wt.%, of which the major part occurs as pyritic sulfur. Results of X-ray diffraction indicate the

The rough lemon pathotype of Alternaria alternata produces host-selective ACR-toxin and causes Alternaria leaf spot disease of the rootstock species rough lemon (Citrus jambhiri) and Rangpur lime (C. limonia). Genes controlling toxin production were localized to a 1.5-Mb chromosome carrying the ACR-toxin biosynthesis gene cluster (ACRT) in the genome of the rough lemon pathotype. A genomic BAC clone containing a portion of the ACRT cluster was sequenced which allowed identification of three open reading frames present only in the genomes of ACR-toxin producing isolates. We studied the functional role of one of these open reading frames, ACRTS1 encoding a putative hydroxylase, in ACR-toxin production by homologous recombination-mediated gene disruption. There are at least three copies of ACRTS1 gene in the genome and disruption of two copies of this gene significantly reduced ACR-toxin production as well as pathogenicity; however, transcription of ACRTS1 and production of ACR-toxin were not completely eliminated due to remaining functional copies of the gene. RNA-silencing was used to knock down the remaining ACRTS1 transcripts to levels undetectable by reverse transcription-polymerase chain reaction. The silenced transformants did not produce detectable ACR-toxin and were not pathogenic. These results indicate that ACRTS1 is an essential gene in ACR-toxin biosynthesis in the rough lemon pathotype of A. alternata and is required for full virulence of this fungus.

Crucial role of Asp408 in the proton translocation pathway of multidrug transporter AcrB: evidence from site-directed mutagenesis and carbodiimide labeling.

The three-component AcrA/AcrB/TolC efflux system of Escherichia coli catalyzes the proton motive force-driven extrusion of a variety of cytotoxic compounds. The inner membrane pump component AcrB belongs to the resistance nodulation and cell division (RND) superfamily and is responsible for drug specificity and energy transduction of the entire tripartite efflux system. Systematic mutational analysis of titratable and polar membrane-located amino acids revealed four residues, D407, D408, K940, and, R971, to be of prime importance for AcrB function. Using matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry, D408 was shown to specifically react with dicyclohexylcarbodiimide (DCCD) in a pH-dependent manner. The apparent pK(a) of D408 of 7.4 would enable binding and release of protons under physiological conditions. In contrast to other secondary transporters, D408 was not protected from carbodiimide modification in the presence of drugs, which supports the notion of spatially separated transport pathways for drugs and protons. This study provides evidence for a substantial role of membrane-located carboxylates as a central element of the proton translocation pathway in AcrB and other members of the RND superfamily.

GNSS navigation satellites are currently being developed by all major players in the science and technology scene, to compete with the GPS system. Because their applications span many different areas, from traffic and cargo control, to geodesy and seismic monitoring, it is required to assess the coherence between the different constellations. BDS is the GNSS system currently developed in China. Its first generation of satellites consisted of 3 geostationnary satellites allowing geolocalisation in China only. In addition to these satellites, other satellites have been launched in geostationnary and geosynchronous orbits, as well as satellites orbiting with a classical GNSS semi-major axis. With these additions, the BDS system possesses 19 operating satellites, and though the system is mostly efficient for geolocalisation in Asia, the satellites are also visible in other parts of the globe. In parallel to the development of the BDS constellation, China has launched the iGMAS (International GNSS Monitoring and Assessment Service) project to develop a global tracking network of multi-GNSS geodetic receivers. One of the goals of this project is to evaluate the efficiency of the BDS constellation as well as the efficiency of the receivers developed by the Chinese laboratories. As part of the Brazilian program COSBAN leaded by the Foreign Affairs Ministry to foster up the science and technology partnership with China, materialized by the collaboration between the Shanghai Astronomical Observatory/CAS and the Observatório Nacional/MCTI, in Rio de Janeiro. Through it the RIOS-iGMAS station was installed at Observatório Nacional, where the RJEP GNSS station already operates as part of the Brazilian reference system. Thus at the Observatório Nacional can be observed satellites from any constellation with both systems of reception, leading to a direct, efficient way to compare the results obtained for each network. In this communication we focus on the determination of the

Full Text Available Abstract – The human communicative activity was always determined, over the centuries, by the use of conversational strategies that the interactants put in place in order to exchange information through illocutionary acts, characterized by various discursive and narrative sequences employed to get communicative purposes during the verbal interaction. Through the analysis of four dialogues extracted from two literary Portuguese language works of two different centuries, we demonstrate how the conversational structures of verbal exchanges have not changed over the time, despite the different schools and literary currents that have occurred since the medieval times until the contemporary era. The text chosen are taken from the novels A queda d'um anjo and Amor de perdição: memorias duma família of Camilo Castelo Branco (1825-1890 and from the contemporary work Não há coincidências of Margarida Rebelo Pinto: the choice of these extracts was not random, but taking into account the use of dialogue as a conversational technique, between characters, by these authors who use it in their fiction works in order to involve more actively the reader on the reported events.

Full Text Available The riparian forests, belonging to the permanent preservation areas, are of fundamental importance for the preservation of water quality and minimize the effects of erosion on soil and thus the sedimentation of river. The land use of these areas cause environmental risks, especially to water resources. The geospatial technologies are, in the current scenario, as a tool that shows the real situation of the area, identifying the critical points, thus contributing to better management of these areas. Therefore, this study aimed to establish a spatial study of APP of the Mossoró river in urban area of municipal district of Mossoró, in the state of Rio Grande do Norte, identifying the main causes of degradation and it's consequences to environment, especially the water resource, through geoprocessing's techniques. Geographic Information System (GIS were used to spatially delimitate the area and image processing. Deforested areas comprised 310 ha, being more concentrated among the East-West Bridge and Barrocas's dam. Edification areas were more concentrated in Santa Luzia's Island and between Castelo Branco and Jerônimo Rosado's Bridges, occupying 78 ha. The areas covered by vegetation comprised 70 ha, which more concentrated in the area of Genesio' dam. There was enough sources of water pollution, especially domestic sewage.

The aim of this work is to examine by means of characterization and dating pottery recently discovery inside archaeological sites recognized with circular earth structure in Acre State - Brazil which may contribute to the research in the reconstruction of part of the pre-history of the Amazonic Basin. These sites are located mainly in the Hydrographic Basin of High Purus River. Three of them were strategic chosen which provide the ceramics: Lobao, in Sena Madureira County at north; Alto Alegre, in Rio Branco County at east and Xipamanu I, in Xapuri County at south. The X-ray diffraction mineral analysis made possible to identify two types of crystal structures of ceramic minerals: quartz and M-Kaolinite. Neutron activation analysis in conjunction with multivariate statistical methods were applied for the ceramic characterization and classification. An homogeneous group was established by all sherds collected from Alto Alegre and was distinct from all the other two groups analyzed. Some of the sherds collected from Xipamanu I appeared in Lobao's urns, probably because they had the same fabrication process. The Lobao's urns presented a homogeneous group. Geochronology of these materials was carried out by Thermoluminescence. The Xipamanu I was the oldest site and Lobao the youngest. The average age of Xipamanu I and Alto Alegre were 2600 and 2070 years respectively. The average age of of occupation was 400 years to Alto Alegre and 970 years to Xipamanu I. The most probably date for Lobao was 1880 years. (author)

Design of New Antibacterial Enhancers Based on AcrB’s Structure and the Evaluation of Their Antibacterial Enhancement Activity

Yi Song

2016-11-01

Full Text Available Previously, artesunate (AS and dihydroartemisinine 7 (DHA7 were found to have antibacterial enhancement activity against Escherichia coli via inhibition of the efflux pump AcrB. However, they were only effective against E. coli standard strains. This study aimed to develop effective antibacterial enhancers based on the previous work. Our results demonstrate that 86 new antibacterial enhancers were designed via 3D-SAR and molecular docking. Among them, DHA27 had the best antibacterial enhancement activity. It could potentiate the antibacterial effects of ampicillin against not only E. coli standard strain but also clinical strains, and of β-lactam antibiotics, not non-β-lactamantibiotics. DHA27 could increase the accumulation of daunomycin and nile red within E. coli ATCC 35218, but did not increase the bacterial membrane permeability. DHA27 reduced acrB’s mRNA expression of E. coli ATCC 35218 in a dose-dependent manner, and its antibacterial enhancement activity is related to the degree of acrB mRNA expression in E. coli clinical strains. The polypeptides from AcrB were obtained via molecular docking assay; the pre-incubated polypeptides could inhibit the activity of DHA27. Importantly, DHA27 had no cytotoxicity on cell proliferation. In conclusion, among newly designed antibacterial enhancers, DHA27 had favorable physical and pharmacological properties with no significant cytotoxicity at effective concentrations, and might serve as a potential efflux pump inhibitor in the future.

It uses the frontier concept developed by F. J. Turner to explain why their open frontier put Brazil and Bolivia in confrontation. This happened because of the Bolivian strategy of granting land to investors from the United States, Great Britain and France, which was interpreted by Brazil as an imperialist action promoted by the United States. This explains why Brazil established a cióse relationship with Chile to confront together their problems in Acre and Antofagasta, which led to the drafting of the Petrópilis (1903 and Paz y Amistad (1904 treaties. The article argues that Bolivia proceeded this way to avoid a Brazilian, Peruvian or Paraguayan territorial advance, seeking the support of the United States to compénsate the imbalance of power.

The introduction of new classification criteria for Sjögren's syndrome, known as the 2016 American College of Rheumatology/European League against Rheumatism Classification Criteria (ACR-EULAR), created a need for the evaluation of its performance in an external cohort. The purpose of this study was to compare the performance of the 2016 ACR-EULAR classification set with the widely used American-European Consensus Group Classification criteria (AECG) in the cohort at the National Institutes of Health, USA, and to compare the performance of the sets in classifying both primary and secondary Sjögren's syndrome (pSS and sSS). The study cohort at the NIH (N = 1,303) was enrolled for clinical suspicion of SS. Participants were classified as SS, pSS, and sSS according to both classification sets. Performance of 2016 ACR-EULAR and AECG sets was compared holding each as gold standard to the other. Statistical analysis of test diagnostics and agreement between the two sets were undertaken. By the AECG set, 701 were classified as having SS (627 pSS, 74 sSS) and 714 were classified with SS (647 pSS, 67 sSS) by the 2016 ACR-EULAR set. Sensitivity and specificity of the two sets were comparable in classifying SS, pSS, and sSS. There was high agreement between the two sets for classifying SS (κ = 0.79), pSS (κ = 0.81), and sSS (κ = 0.87). The specificity of the 2016 ACR-EULAR set was significantly higher for classifying sSS than pSS, while the sensitivity was similar for the two disease groups. However, this pattern was also exhibited by the AECG set. There was high agreement between the two classification sets with comparable performance diagnostics. There was no evidence of superior performance value by the new 2016 ACR-EULAR set over the AECG set, and the two sets were found to be equivalent. Findings from our cohort indicate that 2016 ACR-EULAR classification could be extended to classification of sSS. Published 2018. This article is a U.S. Government work and

To assess joint involvement and the contribution of musculoskeletal ultrasound (MSUS) to the novel European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) 2012 classification criteria in patients with polymyalgia rheumatic (PMR). MSUS was performed in 54 consecutive patients with recent-onset PMR. Biceps tenosynovitis of at least 1 shoulder has been observed in 70.4% of patients, and 64.8% had a bilateral biceps tenosynovitis. Subdeltoid bursitis (27.8% unilateral, 5.6% bilateral), glenohumeral synovitis (22.2% unilateral, 9.3% bilateral), and hip involvement (22.2% unilateral, 16.7% bilateral) were observed less frequently. The sensitivities of the classification criteria were 85.2% for EULAR/ACR without MSUS and 81.5% for EULAR/ACR with MSUS. The most common MSUS pathology was a biceps tenosynovitis. However, US findings had no effect on the sensitivity of the novel EULAR/ACR criteria for PMR.

Full Text Available INTRODUÇÃO: No Brasil verifica-se um descompasso entre o aumento das necessidades de atenção à saúde e de sua oferta. O Sistema Único de Saúde, cujas deretrizes preconizam a atenção universal e eqüânime, determina a relevância desta temática dentro do campo da avaliação dos serviços de saúde. Assim, foram estudados dois ambulatórios de pediatria de um hospital universitário, um geral e outro de uma subespecialiadade (pneumologia, comparando os usuários quanto ao acesso. MÉTODO: Foram aplicados 221 questionários entre clientes de ambos os ambulatórios de pediatria com o objetivo de se estudar e comparar variáveis socioeconômicas, procedência, acesso aos referidos ambulatórios e outros serviços de saúde. RESULTADOS: Evidenciou-se grande dificuldade de locomoção dos pacientes, a maioria dos quais são encaminhados por serviços de saúde locais. Dos pacientes atendidos 40% não receberam nenhum atendimento anteriormente à sua chegada ao hospital, fato que decorre principalmente de seu baixo nível socioeconômico, que os torna dependentes exclusivamente dos serviços públicos de saúde. A comparação entre os dois ambulatórios mostra que os pacientes do ambulatório de especialidade têm melhor nível socioeconômico e são menos dependentes dos serviços públicos, configurando desta forma uma situação de ineqüidade. CONCLUSÕES: É apontado o melhor nível socioeconômico dos usuários da especialidade bem como questões organizacionais do próprio serviço como os responsáveis pela iniqüidade verificada.

Geyer, P.; Blank, H.; Alheit, H.

2006-01-01

Background and Purpose: the suitability of the storage phosphor plate system ACR 2000 RT (Eastman Kodak Corp., Rochester, MN, USA), that is destined for portal verification as well as for portal simulation imaging in radiotherapy, had to be proven by the comparison with a highly sensitive verification film. Material and Methods: the comparison included portal verification images of different regions (head and neck, thorax, abdomen, and pelvis) irradiated with 6- and 15-MV photons and electrons. Each portal verification image was done at the storage screen and the EC registered film as well, using the EC-L registered cassettes (both: Eastman Kodak Corp., Rochester, MN, USA) for both systems. The soft-tissue and bony contrast and the brightness were evaluated and compared in a ranking of the two compared images. Different phantoms were irradiated to investigate the high- and low-contrast resolution. To account for quality assurance application, the short-time exposure of the unpacked and irradiated storage screen by green and red room lasers was also investigated. Results: in general, the quality of the processed ACR images was slightly higher than that of the films, mostly due to cases of an insufficient exposure to the film. The storage screen was able to verify electron portals even for low electron energies with only minor photon contamination. The laser lines were sharply and clearly visible on the ACR images. Conclusion: the ACR system may replace the film without any noticeable decrease in image quality thereby reducing processing time and saving the costs of films and avoiding incorrect exposures.

Drug efflux pumps confer multidrug resistance to dangerous pathogens which makes these pumps important drug targets. We have synthesised a novel series of compounds based on a 2-naphthamide pharmacore aimed at inhibiting the efflux pumps from Gram-negative bacteria. The archeatypical transporter AcrB from Escherichia coli was used as model efflux pump as AcrB is widely conserved throughout Gram-negative organisms. The compounds were tested for their antibacterial action, ability to potentiate the action of antibiotics and for their ability to inhibit Nile Red efflux by AcrB. None of the compounds were antimicrobial against E. coli wild type cells. Most of the compounds were able to inhibit Nile Red efflux indicating that they are substrates of the AcrB efflux pump. Three compounds were able to synergise with antibiotics and reverse resistance in the resistant phenotype. Compound A3, 4-(isopentyloxy)-2-naphthamide, reduced the MICs of erythromycin and chloramphenicol to the MIC levels of the drug sensitive strain that lacks an efflux pump. A3 had no effect on the MIC of the non-substrate rifampicin indicating that this compound acts specifically through the AcrB efflux pump. A3 also does not act through non-specific mechanisms such as outer membrane or inner membrane permeabilisation and is not cytotoxic against mammalian cell lines. Therefore, we have designed and synthesised a novel chemical compound with great potential to further optimisation as inhibitor of drug efflux pumps. Copyright © 2017 Elsevier Ltd.

Modelling of the Liquid Injection Shutdown System (LISS) in the ACR-1000 reactor core must account for the major phenomena that occur following its activation, namely the moderator hydraulics and core neutronics. The former requires modelling of the poison volumes, their time of entry into the reactor, and their propagation into the moderator after emission from the nozzle. The latter requires the reactivity worth of varying volumes and geometries of poisoned moderator fluid in order to simulate the reactivity effect of the injected poison. The time-dependent poison map is generated from hydraulic calculations, and then the neutronics data for standard geometries and concentrations is constructed using DRAGON. (author)

Antibacterial Efficacy of Polysaccharide Capped Silver Nanoparticles Is Not Compromised by AcrAB-TolC Efflux Pump

Full Text Available Antibacterial therapy is of paramount importance in treatment of several acute and chronic infectious diseases caused by pathogens. Over the years extensive use and misuse of antimicrobial agents has led to emergence of multidrug resistant (MDR and extensive drug resistant (XDR pathogens. This drastic escalation in resistant phenotype has limited the efficacy of available therapeutic options. Thus, the need of the hour is to look for alternative therapeutic approaches to mitigate healthcare concerns caused due to MDR bacterial infections. Nanoparticles have gathered much attention as potential candidates for antibacterial therapy. Equipped with advantages of, wide spectrum bactericidal activity at very low dosage, inhibitor of biofilm formation and ease of permeability, nanoparticles have been considered as leading therapeutic candidates to curtail infections resulting from MDR bacteria. However, substrate non-specificity of efflux pumps, particularly those belonging to resistance nodulation division super family, have been reported to reduce efficacy of many potent antibacterial therapeutic drugs. Previously, we had reported antibacterial activity of polysaccharide-capped silver nanoparticles (AgNPs toward MDR bacteria. We showed that AgNPs inhibits biofilm formation and alters expression of cytoskeletal proteins FtsZ and FtsA, with minimal cytotoxicity toward mammalian cells. In the present study, we report no reduction in antibacterial efficacy of silver nanoparticles in presence of AcrAB-TolC efflux pump proteins. Antibacterial tests were performed according to CLSI macrobroth dilution method, which revealed that both silver nanoparticles exhibited bactericidal activity at very low concentrations. Further, immunoblotting results indicated that both the nanoparticles modulate the transporter AcrB protein expression. However, expression of the membrane fusion protein AcrA did show a significant increase after exposure to AgNPs. Our results

Tinnitus is the perception of sound in the absence of an external source. It is a common symptom that can be related to hearing loss and other benign causes. However, tinnitus may be disabling and can be the only symptom in a patient with a central nervous system process disorder. History and physical examination are crucial first steps to determine the need for imaging. CT and MRI are useful in the setting of pulsatile tinnitus to evaluate for an underlying vascular anomaly or abnormality. If there is concomitant asymmetric hearing loss, neurologic deficit, or head trauma, imaging should be guided by those respective ACR Appropriateness Criteria ® documents, rather than the presence of tinnitus. Imaging is not usually appropriate in the evaluation of subjective, nonpulsatile tinnitus that does not localize to one ear. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment. Copyright © 2017 American College of Radiology.

Effect of multicell DRAGON calculations depends on the environment on the DONJON predictions for the ACR-1000

International Nuclear Information System (INIS)

Duquette, J.-S.

2009-01-01

For understanding the behavior of a nuclear reactor core, it is necessary to make a full core calculation in order to compute the neutrons flux. To obtain the neutrons flux, solving the Boltzmann transport equation is required. That is not a simple task and it is impossible to analytically fend the solution of the neutrons transport equation on a complex core. Following a series of approximations, it is possible to numerically solve the neutrons transport equation. The solution of this equation is done step by step. Calculations will be performed over the ACR-1000 core. The Advanced CANDU Reactor (ACR-1000) is a generation III+ heavy water moderated and light water cooled reactor. It is a 1200 MW(e) power reactor. Amongst the ACR-1000 design parameters that differ from the CANDU 6, the reduced lattice pitch and the use of light water coolant and enriched fuel are the three most important. Those features modify the behavior of the neutrons in the ACR compared to the CANDU 6. The impact of the tight lattice is that a cell is more strongly coupled to its neighbor. The objective of this work is to determine the impact of the environment on the cell properties of the ACR-1000. Those properties will be used to perform full core calculations. The neutron transport calculations are performed with DRAGON whereas for the diffusion calculation on a full core. The code DONJON will be used. The DRAGON reference transport calculation will be made on a single cell. Then, a series of calculations will be performed using DRAGON over two types of assemblies, the first modelling the core interior and the second, modelling the core periphery. Moreover, the fuel age will sometimes be homogeneous, sometimes heterogeneous. The fuel will be burned during six hundred days. One thus obtains libraries of macroscopic cross sections over a six hundred days interval for various simulations. Thereafter, we will determine the effect of a neutrons transport multicell calculation on various DONJON

This paper examines the end flux peaking in ACR-1000 fuel bundles. Reactor physics simulations are performed with MCNP to assess the steady state end-flux peaking in an infinite lattice of ACR fuel, as well as to quantify the peaking that occurs during refuelling. 3-dimensional MCNP models are created based on the detailed geometry of the fuel bundle. Detailed position-dependent fuel compositions are obtained from MONTEBURNS which couples MCNP and ORIGIN2.2. Axial and radial power profiles are obtained for both fresh and mid-burnup fuel bundles in an infinite lattice. Subsequently an assessment of the impact of a refuelling transient on the power profiles is performed. The refuelling transient is found to increase the end flux peaking in the region adjacent to light water. (authors)

This Pinellas County, Florida, Site Environmental Restoration Project Semiannual Progress Report for the 4.5 Acre Site describes environmental restoration activities for the 4.5 Acre Site located in Pinellas County, Largo, Florida (Figure 1). The former U.S. Department of Energy (DOE) Pinellas Plant facility consisted of the 4.5 Acre Site and what is now the STAR Center (Young - Rainey Science, Technology, and Research Center). Both the 4.5 Acre Site and the STAR Center are part of the overall Pinellas County, Florida, Site (Figure 2). The 4.5 Acre Site is located immediately northwest of the STAR Center, in the northeast quarter of Section 13, Township 30 South, Range 15 East. DOE owned this parcel from 1957 to 1972, at which time it was sold to a private landowner. During the period of DOE ownership, the property was used for the disposal of drums of waste resins and solvents. As a result of this practice, the surficial aquifer was impacted by volatile organic compounds (VOCs)-trichloroethene (TCE), cis-1,2-dichloroethene (cDCE), trans-1,2-dichloroethene (tDCE), vinyl chloride (VC), and benzene. Detailed background information for the site is contained in the Long-Term Surveillance and Maintenance Plan for the Pinellas Site (DOE 2016). That document and other site-related documents can be accessed at this website: http://www.lm.doe.gov/Pinellas/Sites.aspx. Recent remediation activities consist of the injection of emulsified soybean oil and the microorganism Dehalococcoides mccartyi (formerly known as Dehalococcoides ethenogenes) into the subsurface in February 2010 and again in July 2013 to enhance contaminant biodegradation (hereafter described as bioinjection). Monitoring the performance of these actions, in the form of monitoring well sampling, is ongoing.

The aim of this report was to propose a definition for erosive disease in the context of inflammatory arthritis in light of the 2010 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) rheumatoid arthritis (RA) criteria for use in clinical practice and studies. A EULAR task force was formed including 16 rheumatologists and one rheumatology fellow. The process was both evidence based and consensus based, and included, between March 2010 and April 2012, analyses of data from two cohorts, two face-to-face meetings, one online voting and one teleconference. The Leiden Early Arthritis Cohort and the French ESPOIR cohort were used for the evidence-based part. The outcome measures, which were initiation of methotrexate therapy, or any disease-modifying antirheumatic drug therapy within the first year of disease and arthritis persistency over 5 years, were studied with the aim to give the best definition of erosive disease. A decision was made to select a definition with a high specificity and focus on patients who did not otherwise fulfil the 2010 ACR/EULAR RA criteria (definition was selected: erosive disease for use in the 2010 ACR/EULAR RA classification criteria is defined when an erosion (defined as a cortical break) is seen in at least three separate joints at any of the following sites: the proximal interphalangeal, the metacarpophalangeal, the wrist (counted as one joint) and the metatarsophalangeal joints on radiographs of both hands and feet. A highly specific definition for erosive disease has thus been formulated.

The correlates of urinary albumin to creatinine ratio (ACR) in a high risk Australian aboriginal community.

Wang, Zaimin; Hoy, Wendy E; Wang, Zhiqiang

2013-08-16

Albuminuria marks renal disease and cardiovascular risk. It was estimated to contribute 75% of the risk of all-cause natural death in one Aboriginal group. The urine albumin/creatinine ratio (ACR) is commonly used as an index of albuminuria. This study aims to examine the associations between demographic factors, anthropometric index, blood pressure, lipid-protein measurements and other biomarkers and albuminuria in a cross-sectional study in a high-risk Australian Aboriginal population. The models will be evaluated for albuminuria at or above the microalbuminuria threshold, and at or above the "overt albuminuria" threshold with the potential to distinguish associations they have in common and those that differ. This was a cross-sectional study of 598 adults aged 18-76 years. All participants were grouped into quartiles by age. Logistic regression models were used to explore the correlates of ACR categories. The significant correlates were systolic blood pressure (SBP), C-reactive protein (CRP), uric acid, diabetes, gamma-glutamyl transferase (GGT) (marginally significant, p=0.054) and serum albumin (negative association) for ACR 17+ (mg/g) for men and 25+ for women. Independent correlates were SBP, uric acid, diabetes, total cholesterol, alanine amino transferase (ALT), Cystatin C and serum albumin (negative association) for overt albuminuria; and SBP, CRP and serum albumin only for microalbuminuria. This is the most detailed modelling of pathologic albuminuria in this setting to date. The somewhat variable association with risk factors suggests that microalbuminuria and overt albuminuria might reflect different as well as shared phenomena.

Full Text Available Palm heart constitutes a major non-timber forest product within the pro poor development strategy in Acre State. The 1990s it witnessed a boom of native palm processing, that proved to be unsustainable and processing units migrated to northern Bolivia.

Recent information from various sources suggests that a new illicit drug, called "oxi", is being spread across Brazil. It would be used in the smoked form and it would look like to crack cocaine: usually small yellowish or light brown stones. As fully released in the media, "oxi" would differ from crack cocaine in the sense that crack would contain carbonate or bicarbonate salts whereas "oxi" would include the addition of calcium oxide and kerosene (or gasoline). In this context, this work presents a chemical profiling comparative study between "oxi" street samples seized by the Civil Police of the State of Acre (CP/AC) and samples associated with both international and interstate drug trafficking seized by the Brazilian Federal Police in Acre (FP/AC). The outcome of this work assisted Brazilian authorities to stop inaccurate and alarmist releases on this issue. It may be of good use by the forensic community in order to better understand matters in their efforts to guide local law enforcement agencies in case such claims reach the international illicit market.

Full Text Available Oxides containing aluminium and barium, optionally with chromium, are refractory with several possible industrial uses. A gel precursor of an oxide having the formula BaO.n(Al2xCr2yO3, where 1Oxidos contendo alumínio e bário, opcionalmente com crômio, são refratários com vários possíveis usos industriais. Foi preparado um gel precursor de um óxido de formula BaO.n(Al2xCr2yO3, com 1rio com uma solução de um sal de bário com solução de um sal de alumínio ou uma solução de um sal de alumínio e um sal de cromo III, formando então um gel que é queimado para se obter o óxido desejado. Filamentos podem ser estraídos duramente a formação do gel ou extrudados de um gel semi-rígido. Estudos de infravermelho com transformada de Fourier, difração de raios X e ressonância magnética nuclear com 27AL mostraram que o bário não é incorporado diretamente na estrutura do gel. Oxidos de alumínio e bário foram obtidos somente após liquefação de espécies de bário. Foi preparada uma mistura de pós adequada para queima para se obter um óxido de fórmula BaO.m[Al2x Cr2y O3] com 4,6rio, óxido de bário, carbonato de bário e mono-aluminato de bário, alumina e/ou alumina hidratada e óxido de cromo III, com quantidades relativas variando para se obter na queima valores desejados de m e de y. Corpos cerâmicos resistentes da fórmula BaO 6 Al2O3 (m=6 e y=0 foram preparados. Estudos de difração de raios X de óxidos de composições (n ou m=6 e y=0 sinterizados em alta temperatura mostraram que mono-aluminato de bário é uma fase intermediária de baixa temperatura. Cromo III reduz a temperatura necessária para formar um óxido de alumínio e bário. É feito um sumário de trabalhos anteriormente publicados.

Switch-loop flexibility affects transport of large drugs by the promiscuous AcrB multidrug efflux transporter.

Science.gov (United States)

Cha, Hi-jea; Müller, Reinke T; Pos, Klaas M

2014-08-01

Multidrug efflux transporters recognize a variety of structurally unrelated compounds for which the molecular basis is poorly understood. For the resistance nodulation and cell division (RND) inner membrane component AcrB of the AcrAB-TolC multidrug efflux system from Escherichia coli, drug binding occurs at the access and deep binding pockets. These two binding areas are separated by an 11-amino-acid-residue-containing switch loop whose conformational flexibility is speculated to be essential for drug binding and transport. A G616N substitution in the switch loop has a distinct and local effect on the orientation of the loop and on the ability to transport larger drugs. Here, we report a distinct phenotypical pattern of drug recognition and transport for the G616N variant, indicating that drug substrates with minimal projection areas of >70 Å(2) are less well transported than other substrates.

Menezes, F.L.; Paschoal, C.M.M.; Ferreira, F.C.L.; Alcantara, M.C.

2015-01-01

The objective of this study was to evaluate the suitability to radiation protection of four diagnostic radiology medical services in the city of Sobral-CE, Northeast of Brazil, and to analyze results of the literature for the cities of Rio Branco-AC, North of Brazil, and Rio de Janeiro-RJ, South-east of Brazil. In Sobral-CE, it was performed interviews and direct observations with reference to Brazilian law, the National Ordinance No.453/1998 of the Ministry of Health that regulates the operation of medical and odontological diagnostic radiology services. The results show the occurrence of many items in disagreement with the standard. The technical and operational infractions have basically due to unfamiliarity with the legislation, the lack of investment in training and/or professional development courses. (authors)

Purpose/Objective(s): To assess the image quality of an integrated MR-Linac system and compare with other MRI systems that are primarily used for diagnostic purposes. Materials/Methods: An ACR MRI quality control (QC) phantom was used to evaluate the image quality of a fully integrated 1.5T MRI-Linac system recently installed at our institution. This system has a new split magnet design which gives the magnetic field strength of 1.5T. All images were acquired with a set of phased-array surface coils which are designed to have minimal attention of radiation beam. The anterior coil rests on a coil holder which keeps the anterior coil’s position consistent for QA purposes. The posterior coil is imbedded in the patient couch. Multiple sets of T1, T2/PD images were acquired using the protocols as prescribed by the ACR on three different dates, ranging 3 months apart. Results: The geometric distortion are within 0.5 mm in the axial scans and within 1mm in the saggital (z-direction) scans. Slice thickness accuracy, image uniformity, ghosting ratio, high contrast detectability are comparable to other 1.5T diagnostic MRI scanners. The low-contrast object detectability are lower comparatively, which is a result of using the body array coil. Additionally, the beam’s-eye-view images (oblique coronal and saggital images) have minimal geometric distortion at all linac gantry angles tested. No observable changes or drift in image quality is found from images acquired 3 month apart. Conclusion: Despite the use of a body array surface coil, the image quality is comparable to that of an 1.5T MRI scanner and is of sufficient quality to pass the ACR MRI accreditation program. The geometric distortion of the MRI system of the integrated MR-Linac is within 1mm for an object size similar to the ACR phantom, sufficient for radiation therapy treatment purpose. The authors received corporate sponsored research grants from Elekta which is the vendor for the MR-Linac evaluated in this

A amostragem da vegetação foi feita pelo método de parcelas, sendo registrado o diâmetro à altura do peito (DAP e a altura dos indivíduos > 1 m de altura. Os resultados indicaram que a floresta plantada apresenta menores valores de DAP médio e área basal, e maior densidade de troncos em relação à floresta natural. A distribuição de indivíduos por classes de altura e a distribuição de troncos por classes diamétricas mostraram que a floresta plantada é mais jovem. Laguncularia racemosa e Rhizophora mangle ocorreram em ambas as florestas, enquanto Avicennia schaueriana foi registrada apenas na floresta plantada. Laguncularia racemosa apresentou maior dominância e densidade relativa em todos os sítios analisados, provavelmente, por ser característica de locais com menor influência marinha e pelo fato do estuário ter sido alterado por perturbações antrópicas.

The aim of this work is to examine by means of characterization and dating pottery recently discovery inside archaeological sites recognized with circular earth structure in Acre State - Brazil which may contribute to the research in the reconstruction of part of the pre-history of the Amazonic Basin. These sites are located mainly in the Hydrographic Basin of High Purus River. Three of them were strategic chosen which provide the ceramics: Lobao, in Sena Madureira County at north; Alto Alegre, in Rio Branco County at east and Xipamanu I, in Xapuri County at south. The X-ray diffraction mineral analysis made possible to identify two types of crystal structures of ceramic minerals: quartz and M-Kaolinite. Neutron activation analysis in conjunction with multivariate statistical methods were applied for the ceramic characterization and classification. An homogeneous group was established by all sherds collected from Alto Alegre and was distinct from all the other two groups analyzed. Some of the sherds collected from Xipamanu I appeared in Lobao's urns, probably because they had the same fabrication process. The Lobao's urns presented a homogeneous group. Geochronology of these materials was carried out by Thermoluminescence. The Xipamanu I was the oldest site and Lobao the youngest. The average age of Xipamanu I and Alto Alegre were 2600 and 2070 years respectively. The average age of of occupation was 400 years to Alto Alegre and 970 years to Xipamanu I. The most probably date for Lobao was 1880 years. (author)

Diallel analyses and estimation of genetic parameters of hot pepper (Capsicum chinense Jacq.

Full Text Available The degree of heterosis in the genus Capsicum spp. is considered high; however, most of the studies refer to the species Capsicum annuum L. In spite of the potential use of F1 hybrids in pungent peppers of the species Capsicum chinense, few studies are available which assess the magnitude of heterosis in this species . This study was carried out to assess heterosis and its components in F1 hybrids from a diallel cross between hot pepper lines (Capsicum chinense and to obtain data on the allelic interaction between the parents involved in the crosses. Trials were made in Rio Branco-Acre, Brazil, from March through October 1997. A randomized complete block design with fifteen treatments and three replications was used. The treatments were five C. chinense accessions (from the Vegetable Germplasm Bank of the Universidade Federal de Viçosa - BGH/UFV and 10 F1 hybrids derived from single crosses between them (reciprocals excluded. Diallel analyses were performed for total yield, fruit length/diameter ratio, fruit dry matter per plant, Xanthomonas campestris pv. vesicatoria incidence, capsaicin yield per plant and number of seeds per fruit. Non-additive genetic effects were larger than additive effects for all the traits assessed. Epistasis was detected for fruit dry matter per plant, capsaicin yield per plant and number of seeds per fruit. In these cases, epistasis seemed to be largely responsible for heterosis expression. Dominant gene action, ranging from incomplete dominance to probable overdominance, was responsible for heterosis in those traits where no epistatic genetic action was detected.

Full Text Available Introducción: Se presentan los resultados de un estudio sobre el efecto de la adopción y aplicación de la política de depósito de documentos (PDD en el Repositorio Científico del Instituto Politécnico de Castelo Branco - Portugal (RCIPCB. Metodología: El trabajo se divide en dos partes. La primera parte se refiere a la posición de los profesores/investigadores bajo el PDD y el depósito de sus trabajos científicos en el Repositorio; la segunda parte se relaciona con el desempeño de la RCIPCB como tal. El estudio se llevó a cabo mediante la aplicación de una encuesta en línea para profesores /investigadores - IPCB (n = 505 - seguida de un análisis estadístico descriptivo. Resultados: el 96,6% de los profesores /investigadores dijeron desconocer el RCIPCB; 66,0% de los encuestados respondió conocer el PDD; sólo el 11,9% de los encuestados indicaron que presentaron cuatro documentos (o más de su producción científica en el año 2011 al Repositorio; 50,8% de los profesores /investigadores dijeron no haber presentado ningún documento en el mismo año. Las explicaciones más citadas para tal comportamiento fueron: falta de tiempo (43,5%; cuestiones relacionadas con la asignación de los derechos de autor (21,7%; y por el olvido (17,4%. Después de la aprobación de la PDD se observó una reducción en el número total de documentos depositados (10,3% y el número de documentos de auto-archivado (44,0%. Conclusiones: Se concluye que la PDD no se ha producido los resultados deseados en relación con el nivel de auto-archivo ni se verificó el crecimiento del Repositorio utilizando la propuesta de archivos mediados. Consideramos la necesidad de medidas adicionales para mejorar el suministro de archivos mediados y el autoarchivo en el RCIPCB.

TU-F-CAMPUS-I-04: Head-Only Asymmetric Gradient System Evaluation: ACR Image Quality and Acoustic Noise

Purpose: A high-performance head-only magnetic resonance imaging gradient system with an acquisition volume of 26 cm employing an asymmetric design for the transverse coils has been developed. It is able to reach a magnitude of 85 mT/m at a slew rate of 700 T/m/s, but operated at 80 mT/m and 500 T/m/s for this test. A challenge resulting from this asymmetric design is that the gradient nonlinearly exhibits both odd- and even-ordered terms, and as the full imaging field of view is often used, the nonlinearity is pronounced. The purpose of this work is to show the system can produce clinically useful images after an on-site gradient nonlinearity calibration and correction, and show that acoustic noise levels fall within non-significant risk (NSR) limits for standard clinical pulse sequences. Methods: The head-only gradient system was inserted into a standard 3T wide-bore scanner without acoustic damping. The ACR phantom was scanned in an 8-channel receive-only head coil and the standard American College of Radiology (ACR) MRI quality control (QC) test was performed. Acoustic noise levels were measured for several standard pulse sequences. Results: Images acquired with the head-only gradient system passed all ACR MR image quality tests; Both even and odd-order gradient distortion correction terms were required for the asymmetric gradients to pass. Acoustic noise measurements were within FDA NSR guidelines of 99 dBA (with assumed 20 dBA hearing protection) A-weighted and 140 dB for peak for all but one sequence. Note the gradient system was installed without any shroud or acoustic batting. We expect final system integration to greatly reduce noise experienced by the patient. Conclusion: A high-performance head-only asymmetric gradient system operating at 80 mT/m and 500 T/m/s conforms to FDA acoustic noise limits in all but one case, and passes all the ACR MR image quality control tests. This work was supported in part by the NIH grant 5R01EB010065.

Nossa base reflexiva foi construída a partir de observações e descrições do território conhecido como "Alta", no casco histórico de Coimbra, Portugal; entrevistas semiestruturadas, com 12 de seus residentes; e com notas de campo, sistematizadas num diário de bordo da pesquisa, construído para o efeito. A construção identitária de grande parte das pessoas idosas encontra-se profundamente ancorada nos territórios onde vivem, principalmente quando estas pessoas residem há muito tempo em um mesmo espaço geográfico, no qual vivenciam uma parte muito substantiva do seu cotidiano. Esta centralidade é, ainda, reforçada quando apresentam mobilidades reduzidas ou condicionadas, quer pelas dificuldades de acessibilidade dos próprios territórios, quer por limitações pessoais, iniciadas e/ou acentuadas na velhice.

This Corrective Action Decision Document/Corrective Action Plan (CADD/CAP) has been prepared for the 92-Acre Area, the southeast quadrant of the Radioactive Waste Management Site, located in Area 5 of the Nevada Test Site (NTS). The 92-Acre Area includes Corrective Action Unit (CAU) 111, 'Area 5 WMD Retired Mixed Waste Pits.' Data Quality Objectives (DQOs) were developed for the 92-Acre Area, which includes CAU 111. The result of the DQO process was that the 92-Acre Area is sufficiently characterized to provide the input data necessary to evaluate corrective action alternatives (CAAs) without the collection of additional data. The DQOs are included as Appendix A of this document. This CADD/CAP identifies and provides the rationale for the recommended CAA for the 92-Acre Area, provides the plan for implementing the CAA, and details the post-closure plan. When approved, this CADD/CAP will supersede the existing Pit 3 (P03) Closure Plan, which was developed in accordance with Title 40 Code of Federal Regulations (CFR) Part 265, 'Interim Status Standards for Owners and Operators of Hazardous Waste Treatment, Storage, and Disposal Facilities.' This document will also serve as the Closure Plan and the Post-Closure Plan, which are required by 40 CFR 265, for the 92-Acre Area. After closure activities are complete, a request for the modification of the Resource Conservation and Recovery Act Permit that governs waste management activities at the NTS will be submitted to the Nevada Division of Environmental Protection to incorporate the requirements for post-closure monitoring. Four CAAs, ranging from No Further Action to Clean Closure, were evaluated for the 92-Acre Area. The CAAs were evaluated on technical merit focusing on performance, reliability, feasibility, safety, and cost. Based on the evaluation of the data used to develop the conceptual site model; a review of past, current, and future operations at the site; and the detailed and comparative

Trichoderma is an anamorphic filamentous fungal genus with immense potential for production of small valuable secondary metabolites with indispensable biological activities. Microbial dynamics of a psychrotrophic strain Trichoderma velutinum ACR-P1, isolated from unexplored niches of the Shiwalik region, bestowed with rich biodiversity of microflora, was investigated for production of nonribosomal peptides (NRPs) by metabolite profiling by intact-cell mass spectrometry (ICMS) employing matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) mass spectrometer. Being the first report on NRPs production by T. velutinum, studies on optimization of growth conditions by Response Surface Methodology (RSM) for production of NRPs by ACR-P1 was carried out strategically. Multifold enhancement in the yield of NRPs belonging to subfamily SF4 with medium chain of amino acid residues having m/z 1437.9, 1453.9, and 1452.0 at pH 5.9 at 20 °C and of subfamily SF1 with long-chain amino acid residues having m/z 1770.2, 1784.2, 1800.1, 1802.1, and 1815.1 was achieved at pH 7.0 at 25 °C. Complexities of natural mixtures were thus considerably reduced under respective optimized culture conditions accelerating the production of novel microbial natural products by saving time and resources.

Humeca Uranium Mill. Nuclear Regulatory Commission's final environmental statement

International Nuclear Information System (INIS)

1976-04-01

The Humeca Uranium Mill is a carbonate-leach uranium ore refining plant with a capacity of about 500 tons of ore per day. Although the present licensing action does not extend to mining, the statement considers the environmental impact of the combined mining and milling project to be conducted by Rio Algom Corporation. The environmental impact, including adverse and beneficial environmental effects of the Rio Algom Uranium Mill, is as follows. (1) Temporary (about 10 years) reassignment of use of about 120 acres of land out of the total 2,573 acres controlled by Rio Algom Corporation. (2) The removal of an estimated 8.4 million pounds of uranium concentrates as a natural resource. This material will eventually be used to produce approximately 6.09 x 10 6 megawatt-days of electricity. (3) Removal and diversion of approximately 100 gallons per minute of local groundwater. (4) Stimulation of the local economy through payment of taxes and direct employment of about 200 persons in San Juan County over the next 10 years. Rio Algom estimates they will pay out over $11 million in salaries over this period of time. (5) The creation of stabilized tailings piles covering about 45 acres involving approximately 1,850,000 tons of solids containing solidified waste chemical and radioactive uranium and its daughter products. (6) Discharge of small quantities of chemicals and radioactive materials (that are not expected to produce discernible effects) into the local environs

Breast cancer is the most common non-skin cancer and the second leading cause of cancer death for women in the United States. Before the introduction of widespread mammographic screening in the mid-1980s, the death rate from breast cancer in the US had remained unchanged for more than 4 decades. Since 1990, the death rate has declined by at least 38%. Much of this change is attributed to early detection with mammography. ACR breast cancer screening experts have reviewed data from RCTs, observational studies, US screening data, and other peer-reviewed literature to update our recommendations. Mammography screening has consistently been shown to significantly reduce breast cancer mortality over a variety of study designs. The ACR recommends annual mammography screening starting at age 40 for women of average risk of developing breast cancer. Our recommendation is based on maximizing proven benefits, which include a substantial reduction in breast cancer mortality afforded by regular screening and improved treatment options for those diagnosed with breast cancer. The risks associated with mammography screening are also considered to assist women in making an informed choice. Copyright © 2017 American College of Radiology. Published by Elsevier Inc.

Full Text Available The purpose of this article is to discuss the role of Rock in Rio: The Musical, as herald of megafestival Rock in Rio. Driven by the success that musicals have reached in Brazil, we believe that the design of this spectacle of music, dance and staging renews the brand of the rock festival, once it adds the force of young and healthy bodies to its concept. Moreover, the musical provides Rock in Rio with some distance from the controversal trilogy of sex, drugs and rock and roll, a strong mark of past festivals around the world. Thus, the musical expands the possibilities of growth for the brand.

Full Text Available Aim: The aim of this study is to investigate occurrence of potential efflux pump inhibitor (EPI against AcrAB-TolC efflux pump in the methanol extract of H. sabdariffa. Materials and Methods: Calyces of H. sabdariffa were purchased from the local market in April 2014, methanol extract of H. sabdariffa was subjected to agar plate diffusion against Escherichia coli TG1 and its ∆acrB-∆tolC and thin layer chromatography (TLC bioassay. The corresponding EPI fraction was eluted by methanol. The synergistic effect of antimicrobials and EPI fraction was measured by minimum inhibitory concentration (MIC determination for E. coli and Erwinia amylovora strains, and the ability of EPI fraction to enhance EtBr accumulation was conducted. Results: E. coli TG1 was more sensitive to the methanol extracts of H. sabdariffa than E. coli ∆acrB-∆tolC, and inhibition zone corresponding to flavones on TLC bioassay plate has been formed which might be related to the fraction of potential EPI. The MIC values revealed that EPI fraction enhanced the activity of the used antimicrobials by 4 to 8 folds in E. coli TG1 and by 4 to 10 folds in E. amylovora 1189. Addition of EPI fraction in a dose-dependent manner increased the intercellular accumulation of Ethidium Bromide (EtBr in the wild type stains of E. coli TG1 and E. amylovora 1189. Conclusion: EPI fraction behaves like a multidrug efflux pump inhibitor and further investigation should be conducted for determination of the chemical structure of EPI fraction.

Stress Introduction Rate Alters the Benefit of AcrAB-TolC Efflux Pumps.

Science.gov (United States)

Langevin, Ariel M; Dunlop, Mary J

2018-01-01

Stress tolerance studies are typically conducted in an all-or-none fashion. However, in realistic settings-such as in clinical or metabolic engineering applications-cells may encounter stresses at different rates. Therefore, how cells tolerate stress may depend on its rate of appearance. To address this, we studied how the rate of stress introduction affects bacterial stress tolerance by focusing on a key stress response mechanism. Efflux pumps, such as AcrAB-TolC of Escherichia coli , are membrane transporters well known for the ability to export a wide variety of substrates, including antibiotics, signaling molecules, and biofuels. Although efflux pumps improve stress tolerance, pump overexpression can result in a substantial fitness cost to the cells. We hypothesized that the ideal pump expression level would involve a rate-dependent trade-off between the benefit of pumps and the cost of their expression. To test this, we evaluated the benefit of the AcrAB-TolC pump under different rates of stress introduction, including a step, a fast ramp, and a gradual ramp. Using two chemically diverse stresses, the antibiotic chloramphenicol and the jet biofuel precursor pinene, we assessed the benefit provided by the pumps. A mathematical model describing these effects predicted the benefit as a function of the rate of stress introduction. Our findings demonstrate that as the rate of introduction is lowered, stress response mechanisms provide a disproportionate benefit to pump-containing strains, allowing cells to survive beyond the original inhibitory concentrations. IMPORTANCE Efflux pumps are ubiquitous in nature and provide stress tolerance in the cells of species ranging from bacteria to mammals. Understanding how pumps provide tolerance has far-reaching implications for diverse fields, from medicine to biotechnology. Here, we investigated how the rate of stressor appearance impacts tolerance. We focused on two distinct substrates of AcrAB-TolC efflux pumps, the

Quantification of aluminium in soil of the Solimões Formation, Acre State, Brazil

Full Text Available The variety of soils in the State of Acre is wide and their chemical profiles are still not fully understood. The nature of the material of origin of these soils is indicated by the high aluminium (Al content, commonly associated with high calcium (Ca and magnesium (Mg contents. The study objective was to use different methods to quantify Al in soils from toposequences formed from material of a sedimentary nature originating from the Solimões Formation, in Acre, Brazil. Trenches were opened at three distinct points in the landscape: shoulder, backslope and footslope positions. Soil samples were collected for physical, chemical, mineralogical analyses. The Al content was quantified using different methods. High Al contents were found in most of these horizons, associated with high Ca and Mg levels, representing the predominant cations in the sum of exchangeable bases. The mineralogy indicates that the soils are still in a low weathering phase, with the presence of significant quantities of 2:1 minerals. Similar Al contents were determined by the methods of NaOH titration, xylenol orange spectrometry and inductively coupled plasma optical emission spectrometry. However, no consistent data were obtained by the pyrocatechol violet method. Extraction with KCl overestimated the exchangeable Al content due to its ability to extract the non-exchangeable Al present in the smectite interlayers. It was observed that high Al contents are related to the instability of the hydroxyl-Al smectite interlayers.

Full Text Available Este artigo teve como objetivo analisar o itinerário dos usuários que tiveram acesso a medicamentos via judicial no estado do Amazonas, Brasil. Trata-se de estudo qualitativo, prospectivo, baseado em dados coletados por meio de entrevistas semiestruturadas com usuários que receberam medicamentos via mandado judicial. A judicialização na saúde mostrou-se um fator agregador ao reconhecimento dos direitos e da cidadania pelos usuários que, na sua trajetória de vida, acabaram adquirindo um grande aprendizado sobre formas de enfrentar a falta de acesso aos medicamentos. Conclui-se que a relação entre o sujeito e o Estado permanece desigual, e o direito à saúde se deu na dimensão individual e restritiva, desconsiderando a dimensão coletiva e a concepção de cidadania.

An international borderland of concern: Conservation of biodiversity in the Lower Rio Grande Valley

Science.gov (United States)

Leslie,, David M.

2016-07-20

The Lower Rio Grande Valley (LRGV) of southern Texas is located on the United States-Mexico borderland and represents a 240-kilometer (150-mile) linear stretch that ends at the Gulf of Mexico. The LRGV represents a unique transition between temperate and tropical conditions and, as such, sustains an exceptionally high diversity of plants and animals—some of them found in few, or no other, places in the United States. Examples include Leopardus pardalis albescens (northern ocelot) and Falco femoralis septentrionalis (northern aplomado falcon)—both endangered in the United States and emblematic of the LRGV. The U.S. Fish and Wildlife Service (USFWS) manages three national wildlife refuges (Santa Ana, Lower Rio Grande Valley, and Laguna Atascosa) that together make up the South Texas Refuge Complex, which actively conserves biodiversity in about 76,006 hectares (187,815.5 acres) of native riparian and upland habitats in the LRGV. These diminished habitats harbor many rare, threatened, and endangered species. This report updates the widely used 1988 USFWS biological report titled “Tamaulipan Brushland of the Lower Rio Grande Valley of South Texas: Description, Human Impacts, and Management Options” by synthesizing nearly 400 peer-reviewed scientific publications that have resulted from biological and sociological research conducted specifically in the four Texas counties of the LRGV in the past nearly 30 years. This report has three goals: (1) synthesize scientific insights gained since 1988 related to the biology and management of the LRGV and its unique biota, focusing on flora and fauna of greatest conservation concern; (2) update ongoing challenges facing Federal and State agencies and organizations that focus on conservation or key natural resources in the LRGV; and (3) redefine conservation opportunities and land-acquisition strategies that are feasible and appropriate today, given the many new and expanding constraints that challenge conservation

Full Text Available The commonly known Pimenta longa is a commercially valuable natural resource found wild in Acre, Brazil. Specifically, three Piperaceae species with contested taxonomic status were studied, Piper hispidinervum, Piper aduncum, and Piper hispidum, to assesses the inter- and intra-specific genetic relationship of 49 Piper genotypes kept in the Pimenta longa germplasm collection at Embrapa Acre, using sixty six Random Amplified Polymorphic DNA (RAPD markers. The DNA polymorphism level detected was high (96.97%, but the marker frequencies for each species showed polymorphism levels of 79.4% for Piper hispidinervum and 5.3% for P. aduncum. The genetic similarity clustering analysis resulted in three distinct groups corresponding to Piper hispidinervum, Piper aduncum, and Piper hispidum. Four and nine characteristic RAPD markers were identified for P. hispidinervum and P. aduncum, respectively, supporting the existence of two separate species. However, six genotypes collected in Tarauacá county formed a distinct subgroup within the P. hispidinervum group and may be considered as an ecotype of this species or an intermediate between the P. hispidinervum and P. aduncum groups. More extensive sampling of both P. hispidinervum and P. aduncum populations throughout the region are needed to further establish their relation and its implication for breeding efforts.

Full Text Available Resumo Uma das principais controvérsias relativas à realização da Copa do Mundo no Brasil diz respeito à construção de novos estádios, sobretudo aqueles indicados como potenciais "elefantes brancos", como é o caso da Arena das Dunas, em Natal. O presente trabalho teve por objetivo avaliar os argumentos que constituem os diferentes discursos acerca da construção da Arena das Dunas. Para tal, acessamos três posições discursivas sobre o assunto: dos organizadores, da imprensa e da sociedade civil. Os dados foram coletados por meio de entrevistas, observação direta e documentos. O método adotado foi a arqueologia foucaultiana e sua análise de discurso. Como lente teórica, adotamos a teoria do pós-desenvolvimento. Nossos achados apontam para duas formações discursivas antagônicas: uma favorável e outra contestadora ao investimento feito na construção da arena.

Em 1982/1983, essa área teve seu processo de reabilitação implementado mediante a hidrossemeadura de gramíneas e leguminosas e o plantio puro de Mimosa scabrella Bentham. Em 1997 foi realizado o primeiro inventário da regeneração natural do Retiro-Branco, aravés da implantação de 19 parcelas permanentes para caracterização inicial do processo de sucessão natural. E em 2000 foi realizado o segundo inventário dessas parcelas para caracterizar o processo de dinâmica da regeneração, o objeto deste trabalho. O processo de dinâmica da regeneração natural foi caracterizado mediante análises quantitativas e qualitativas da distribuição diamétrica. Os estudos indicaram que o monitoramento mediante inventário florestal contínuo, com parcelas permanentes setorizadas, é uma ferramenta viável para avaliações da dinâmica da regeneração natural, rumo à compreensão dos caminhos da sucessão. Foi caracterizado o processo de estratificação da regeneração natural, em que as espécies pioneiras e clímax foram as principais componentes do estrato inferior e as secundárias, as principais componentes do estrato superior. O povoamento florestal do Retiro-Branco está sobre intensa atividade de estruturação, caracterizando o estágio inicial do processo de sucessão. As espécies secundárias são as de maior dominância nas maiores classes de altura e de diâmetro, sendo as principais responsáveis pela edificação do estrato superior. A prognose da distribuição diamétrica, realizada mediante o emprego da Cadeia de Markov, foi uma ferramenta de fácil implementação e que permitiu prever o caminho do processo de sucessão para o povoamento todo e para os grupos ecológicos de espécies, ampliando o entendimento dos mecanismos que regem o comportamento

Logging Activity in the Trinational Amazonian Region of Pando/Bolivia, Acre and Rond“nia/Brazil, and Madre de Dios/Peru: Analysis of Existing Data

Mendoza, E.; Brilhante, S. H.; Brown, I.; Peralta, R.; Rivero, S.; Melendez, N.

2002-12-01

Logging activity in the trinational southwestern Amazonia will grow in importance as a driver of regional land-use change as expanding road access facilitates both timber extraction and transport to international markets. Official data on current activity in this ~50 million ha region are limited and inconsistent with differences as much as twenty-fold between official estimates; nevertheless, they serve as guides for understanding the relative magnitude of logging activities. For 2000, an estimated 5 million m3 of timber were commercialized in Rondonia, 400,000 m3 in Acre, Brazil, and 200,000 m3 for the combined departments of Pando, Bolivia and Madre de Dios, Peru. About 70% of this timber originates from clear cutting done for pasture and agriculture activities, nearly a third from unregulated selective logging, and only 2% from managed selective logging. Eight timber species are preferentially extracted. The total area for timber concessions in Acre, Pando and Madre de Dios extends to about 4 million ha for a potential timber supply of 65 million m3. About 150,000 m3/yr of illegal timber is confiscated by federal and state agencies in Acre, Pando and Madre de Dios. Problems of enforcement in the region are due principally to the lack of trained personnel and little cooperation among agencies of the three countries. Proposed development plans indicate a 3- to >10-fold increase in logging activity in the Acre and Pando regions during the coming decade. More detailed studies are urgently needed to guide sustainable development of this resource in southwestern Amazonia.

Full Text Available Neste artigo consideramos os problemas ambientais globais dentro do conceito de limiares planetários, em convergência com os últimos avanços das ciências naturais. Nesse contexto, nosso objetivo é explorar o papel do Brasil na governança do espaço de operação seguro para a humanidade, avaliando como o país complementa o enorme capital ambiental físico que possui com ações políticas específicas orientadas para uma economia verde de baixo carbono (EVBC, tanto no âmbito doméstico quanto no internacional. Para atingir essa meta, em primeiro lugar discutimos conceitualmente a economia verde de baixo carbono como paradigma de desenvolvimento compatível com um espaço de operação seguro para a humanidade; em segundo lugar, analisamos a Rio+20 pelo prisma da governança global dos limiares planetários e pela atuação brasileira na Cúpula; e finalmente fazemos um diagnóstico da situação do Brasil em relação ao novo paradigma de desenvolvimento. Como conclusões da análise, destacamos a crescente distância entre a aceleração dos problemas da interdependência - especialmente a definição de um espaço seguro de operação para a humanidade - e os mecanismos globais de governança existentes, derivada de um sistema internacional bloqueado e dominado por forças conservadoras. O resultado frustrante da Rio+20 é evidência clara dessa defasagem. Nessa dinâmica, o Brasil tem o potencial para ser um ator central da governança dos limiares planetários, por seu vasto capital ambiental físico. No entanto, o mínimo avanço da EVBC no país degrada essa capacidade de agência, e o torna uma potência ambiental subdesenvolvida (underachiever environmental power.

Full Text Available The production of organically grown tomatoes in the Amazonian region of Brazil is difficult due to inherent phytosanitary issues. The objectives of the present investigation were to evaluate the productivity of grafted tomato plants (Solanumlycopersicum cv. Santa Adélia grown organically in Rio Branco, Acre, Brazil, and to assess scion/rootstock compatibility under organic growth conditions. The Solanum species employed as rootstocks were S. gilo (jiló, S. lycocarpum (jurubebão, S. stramonifolium (jurubeba vermelha and S. viarum (joá, while the susceptible S.lycopersicum cultivar Santa Adélia was the scion. Ungrafted tomato plants and tomato grafted on tomato rootstock were employed as controls. The experiment was arranged in a completely randomized block design with six treatments and five repetitions of five plants each. Data were submitted to analysis of variance and the significance of differences between treatments were determined using the Tukey test (P<0.05. All ungrafted tomato plants and those comprising tomato grafted on S.lycopersicum rootstock became infected by brown rot and perished. The total numbers of fruits, numbers of marketable fruits, mean masses of fruits, total productivities and productivities of marketable fruits associated with tomato grafted on S. gilo, S. lycocarpum and S. stramonifolium rootstocks were significantly higher (P<0.05 than the equivalent values obtained with tomato grafted on S. viarum rootstock. S. gilo exhibited the best compatibility index (1.11 of all rootstock/scion combinations studied.

Full Text Available O Paraguai é o rio-tronco do trato de sistemas deposicionais do Pantanal. Com base em dados de sensores remotos e verificação de campo, foi realizado mapeamento geomorfológico da planície do rio Paraguai no trecho entre as confluências dos rios Cuiabá e Miranda, onde foram reconhecidas formas deposicionais atuais e antigas. A análise das associações de formas permitiu estabelecer proposta de evolução geomorfológica para a área, mas os eventos carecem ainda de datação precisa por métodos geocronológicos. Uma rede de drenagem abandonada multicanais está parcialmente preservada na planície, sendo composta por formas de canais com diques marginais que evidenciam período de menor descarga fluvial, provavelmente do Pleistoceno tardio ao Holoceno inferior. Um sistema constituído por paleocinturões de meandros trunca a paleorrede de drenagem multicanais, registrando aumento na umidade e na descarga fluvial. Sob essas condições o rio Paraguai construiu um sistema composto por cinturões de meandros com direção aproximada norte-sul no Holoceno inferior/médio. Agradação dos cinturões favoreceu importante evento de avulsão, com a mudança do curso do rio Paraguai para o cinturão de meandros atual no Holoceno superior. As gerações de formas identificadas e mapeadas resultaram num padrão de sobreposição de diferentes estilos fluviais, que registram significativas mudanças hidrológicas na planície desde o Pleistoceno tardio.

Summary of the ACRE inaugural meeting.

Bloomgarden, Zachary T

2009-01-01

The charter meeting of the Association of Clinical Researchers and Educators (ACRE) provided a powerful set of arguments against assertions that physician-industry collaboration is harmful and represents a "conflict of interest." Such collaboration has, in fact, improved medical care for patients, a case made overwhelmingly by patients and patient advocacy groups at the meeting. The contentions that physician-industry collaboration is problematic are not based on evidence. They depend on unjustified generalization from inevitable, sometimes egregious, but vanishingly uncommon adverse outcomes of industry-physician interaction without reference to how so much more commonly these interactions add value. Furthermore, the claim that physician-industry collaboration is unprofessional is refuted by rational scrutiny. Indeed, the term "conflict of interest" itself is vague, inviting subjectivity and deserving to be rejected. The unwarranted success of conflict of interest regulation has prevailed because of the failure of physicians, educators, and innovators, through apathy and intimidation, to pay attention to its fallacies and resist its dangers. It has arisen from activist ambitions and from misalignment between the purposes of medical practitioners, educators, and innovators and those of administrators in medical journals and in academic medical centers. The media and politicians have not appreciated these misalignments and have accepted conflict of interest arguments at face value. Regulation emanating from conflict of interest criticism is confusing, onerous, expensive, disrespectful, and damaging. Prohibitions against speaking about medical products inhibit physician and patient education concerning rapidly emerging and complex therapies. Input by physicians cognizant of compliance requirements into such presentations should be encouraged. Restrictions to the free flow of corporate support of academic health centers, professional societies, and patient

Full Text Available Tigecycline is one of the few therapeutic options for treating infections caused by some multi-drug resistant pathogens, such as Klebsiella pneumoniae. However, tigecycline-resistant K. pneumoniae has been discovered recently in China. From 2009 to 2013, nine tigecycline-resistant K. pneumoniae isolates were identified in our hospital. Six of nine strains were identified before using tigecycline. To investigate the efflux-mediated resistance mechanisms of K. pneumoniae, the expression of efflux pump genes (acrA, acrB, tolC, oqxA and oqxB and pump regulators (acrR, marA, soxS, rarA, rob and ramA were examined by real-time RT-PCR. Molecular typing of the tigecycline resistant strains was performed. ST11 was the predominant clone of K. pneumoniae strains, while ST1414 and ST1415 were novel STs. Efflux pump inhibitor (EPI-carbonyl cyanide chlorophenylhydrazone (CCCP was able to reverse the resistance patterns of 5 resistant K. pneumoniae strains. In comparison with strain A111, a tigecycline-susceptible strain (negative control, we found that the expression levels of efflux pump genes and pump regulators were higher in a majority of resistant strains. Higher expression levels of regulators rarA (2.41-fold, 9.55-fold, 28.44-fold and 18.31-fold, respectively and pump gene oqxB (3.87-fold, 31.96-fold, 50.61-fold and 29.45-fold, respectively were observed in four tigecycline resistant strains (A363, A361, A368, A373, respectively. Increased expression of acrB was associated with ramA and marA expression. To our knowledge, studies on tigecycline resistance mechanism in K. pneumoniae are limited especially in China. In our study, we found that both efflux pump AcrAB-TolC and OqxAB contributed to tigecycline resistance in K. pneumoniae isolates.

Foram observadas 222 depressões fechadas em divisores de drenagem, indicando forte atuação de mecanismos geoquímicos. Por outro lado, o reduzido número de voçorocas (33 e a presença de pacotes sedimentares poucos espessos (média de 7 metros, apontam a baixa efetividade dos processos mecânicos na bacia, sobretudo ao compararmos com a sub-bacia do rio Piracema, tributária do rio Bananal, com 117 voçorocas, terraços de até 23 metros de espessura e apenas 1 depressão fechada. Internamente, a bacia do rio Turvo apresentou variações, onde, de modo geral, a sub-bacia do rio das Pedras concentrou 21 das 33 voçorocas ativas, os mais espessos pacotes fluviais e apenas 16 depressões fechadas. Assim, conclui-se que a bacia do rio Turvo é fortemente influenciada pelos processos de denudação química, e a sub-bacia do rio das Pedras apresenta as maiores características da atuação do trabalho mecânico de toda a bacia.

Imaging is paramount in the setting of blunt trauma and is now the standard of care at any trauma center. Although anteroposterior radiography has inherent limitations, the ability to acquire a radiograph in the trauma bay with little interruption in clinical survey, monitoring, and treatment, as well as radiography's accepted role in screening for traumatic aortic injury, supports the routine use of chest radiography. Chest CT or CT angiography is the gold-standard routine imaging modality for detecting thoracic injuries caused by blunt trauma. There is disagreement on whether routine chest CT is necessary in all patients with histories of blunt trauma. Ultimately, the frequency and timing of CT chest imaging should be site specific and should depend on the local resources of the trauma center as well as patient status. Ultrasound may be beneficial in the detection of pneumothorax, hemothorax, and pericardial hemorrhage; transesophageal echocardiography is a first-line imaging tool in the setting of suspected cardiac injury. In the blunt trauma setting, MRI and nuclear medicine likely play no role in the acute setting, although these modalities may be helpful as problem-solving tools after initial assessment. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances in which evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment. Copyright © 2014 American College of Radiology.

Full Text Available Nos primórdios dos balneários no Rio Grande do Sul, encontravam-se alguns imigrantes alemães, não apenas entre os banhistas, mas também entre os empresários do incipiente ramo do curismo-turismo. Era um grupo pequeno de imigrantes de origem urbana que, em geral, já conhecia as vantagens curativas ou revigorantes dos banhos em balneários europeus. Entre eles destacavam-se os médicos, importantes emissores de um discurso científico em prol dos balneários. As práticas terapêuticas de banhos de mar chegaram ao Brasil meridional pela imigração européia da segunda metade do século XIX, embora sua difusão só tenha ocorrido na primeira metade do século seguinte, quando se desenvolveram as primeiras praias balneárias no Rio Grande do Sul.In the early days of bathing resorts some German immigrants were found not only among the bathers, but also among the entrepreneurs of the incipient branch of 'curism-tourism'. It was a small group of immigrants of urban origin who, in general, already knew the curative or reinvigorating advantages of the baths in European bathing resorts. Among them, doctors were prominent, important emissaries of a scientific discourse in favor of bathing resorts. The therapeutic practices of bathing in the sea arrived to meridional Brazil with the European immigration of the second half of the nineteenth century, although its diffusion only took place in the first half of the following century, when the first bathing beaches in Rio Grande do Sul were developed.

Full Text Available Este artigo objetiva compreender os significados de uma partida de futebol entre jogadores autodeclarados pretos e brancos que ocorreram em São Paulo, no dia 13 de Maio, data comemorativa do fim da escravidão: o jogo "Preto x Branco". Para tanto, concentramo-nos nas matérias jornalísticas publicadas pelos principais periódicos de São Paulo entre os dias 10 a 15 de Maio entre 1927 até 1939, período de realização dos jogos. Além dos jornais, foi visitado o museu da Federação Paulista de Futebol que disponibilizou as informações necessárias para entendermos a trajetória desses jogos. Concluímos que a idealização de uma partida dessa natureza no dia "13 de maio" teria como função, além de prevenir do esquecimento e manter viva a lembrança da escravidão, reforçar a imagem de um país que era tomado como um modelo a ser seguido no que diz respeito ao tema étnico-racial.This paper aims to understand the meanings of a soccer match, between players who self-declared themselves as black or white, occurred in São Paulo on May 13th, the date commemorating the end of slavery: the game "Black x White". For this, we focused on journalistic material published by leading newspapers of São Paulo from May 10th to 15th, during 1927 and 1939, when the games were held. Additionally, a visit to the museum of the Paulista Football Federation provided the information necessary to understand the trajectory of these games. We concluded that the idealization of a game like this on "May 13th" would have the purpose not only to prevent forgetfulness and to keep alive the memory of slavery, but also to strengthen the image of a country taken as a model to be followed, with respect to the ethnic-racial subject.
