Barrett's Esophagus and Associated Adenocarcinoma : studies on pathogenesis, clinical staging and cost-utility of cancer treatment

Esophageal and gastroesophageal junction (GEJ) adenocarcinoma is rapidly increasing disease with a pathophysiology connected to oxidative stress. Exact pre-treatment clinical staging is essential for optimal care of this lethal malignancy. The cost-effectiviness of treatment is increasingly important. We measured oxidative metabolism in the distal and proximal esophagus by myeloperoxidase activity (MPA), glutathione content (GSH), and superoxide dismutase (SOD) in 20 patients operated on with Nissen fundoplication and 9 controls during a 4-year follow-up. Further, we assessed the oxidative damage of DNA by 8-hydroxydeoxyguanosine (8-OHdG) in esophageal samples of subjects (13 Barrett s metaplasia, 6 Barrett s esophagus with high-grade dysplasia, 18 adenocarcinoma of the distal esophagus/GEJ, and 14 normal controls). We estimated the accuracy (42 patients) and preoperative prognostic value (55 patients) of PET compared with computed tomography (CT) and endoscopic ultrasound (EUS) in patients with adenocarcinoma of the esophagus/GEJ. Finally, we clarified the specialty-related costs and the utility of either radical (30 patients) or palliative (23 patients) treatment of esophageal/GEJ carcinoma by the 15 D health-related quality-of-life (HRQoL) questionnaire and the survival rate. The cost-utility of radical treatment of esophageal/GEJ carcinoma was investigated using a decision tree analysis model comparing radical, palliative, and hypothetical new treatment. We found elevated oxidative stress ( measured by MPA) and decreased antioxidant defense (measured by GSH) after antireflux surgery. This indicates that antireflux surgery is not a perfect solution for oxidative stress of the esophageal mucosa. Elevated oxidative stress in turn may partly explain why adenocarcinoma of the distal esophagus is found even after successful fundoplication. In GERD patients, proximal esophageal mucosal anti-oxidative defense seems to be defective before and even years after successful antireflux surgery. In addition, antireflux surgery apparently does not change the level of oxidative stress in the proximal esophagus, suggesting that defective mucosal anti-oxidative capacity plays a role in development of oxidative damage to the esophageal mucosa in GERD. In the malignant transformation of Barrett s esophagus an important component appears to be oxidative stress. DNA damage may be mediated by 8-OHdG, which we found to be increased in Barrett s epithelium and in high-grade dysplasia as well as in adenocarcinoma of the esophagus/GEJ compared with controls. The entire esophagus of Barrett s patients suffers from increased oxidative stress ( measured by 8-OhdG). PET is a useful tool in the staging and prognostication of adenocarcinoma of the esophagus/GEJ detecting organ metastases better than CT, although its accuracy in staging of paratumoral and distant lymph nodes is limited. Radical surgery for esophageal/GEJ carcinoma provides the greatest benefit in terms of survival, and its cost-utility appears to be the best of currently available treatments.

A ilusão do sufrágio universal na Constituição de 1891

Aborda a pretensa introdução do sufrágio universal no Brasil, pela Constituição de 1891. Analisa as acepções dadas ao conceito e sua abrangência no final do século XIX. Descreve a legislação eleitoral do final do período monárquico e primórdios da república. Discute a temática das qualificações e exclusões eleitorais, motivadas pelo voto censitário, pelo analfabetismo e pelo sexo. Identifica as origens das alterações eleitorais ocorridas, em termos de autores, interesses e beneficiários.

Os direitos políticos nas Constituições de 1891 e 1934

Analisa a evolução dos direitos políticos no Brasil a partir das constituições de 1891 e 1934, cartas políticas consideradas democráticas pela historiografia. Enfoca o contexto histórico das constituições sob análise, introduzindo a temática dos direitos políticos no processo de evolução do constitucionalismo brasileiro. Propõe-se a entender, sem fazer propriamente uma confrontação literal das Constituições de 1891 e 1934, como os direitos políticos se fizeram inscrever nestes textos constitucionais e demonstrar, à luz do processo histórico, quais as influências e origens que determinaram a positivação desses direitos bem como mostrar em que medida esses direitos ganharam efetividade sob a égide das cartas políticas analisadas. Questiona até que ponto os direitos políticos existiram, de fato - já que existiram de direito - nas duas primeiras Constituições democráticas brasileiras. Nesse sentido, desenvolve, ainda que de forma breve, uma conceituação jurídica da expressão "Direitos Políticos". Busca então a origem histórica dos direitos políticos, situando no contexto, as origens do sufrágio universal. Num outro momento, analisa o papel das elites intelectuais no processo de institucionalização dos direitos políticos no Brasil. Ao final, procura mostrar o contexto histórico em que estiveram inseridas as Constituições analisadas, para que em seguida se pontue, se descreva e analise as repercussões dos direitos políticos inscritos nos textos constitucionais estudados.

Noise levels and sources in the Stellwagen Bank National Marine Sanctuary and the St. Lawrence River Estuary

Although ambient (background) noise in the ocean is a topic that has been widely studied since pre-World War II, the effects of noise on marine organisms has only been a focus of concern for the last 25 years. The main point of concern has been the potential of noise to affect the health and behavior of marine mammals. The Stellwagen Bank National Marine Sanctuary (SBNMS) is a site where the degradation of habitat due to increasing noise levels is a concern because it is a feeding ground and summer haven for numerous species of marine mammals. Ambient noise in the ocean is defined as “the part of the total noise background observed with an omnidirectional hydrophone.” It is an inherent characteristic of the medium having no specific point source. Ambient noise is comprised of a number of components that contribute to the “noise level” in varying degrees depending on where the noise is being measured. This report describes the current understanding of ambient noise and existing levels in the Stellwagen Bank National Marine Sanctuary. (PDF contains 32 pages.)

O Apostolado Positivista e o projeto da Ditadura Republicana no Brasil (1889-1891)

O objetivo da pesquisa foi buscar, por meio de um estudo aprofundado, informações relevantes da ação política do Apostolado Positivista do Brasil na transição entre a Monarquia e a República. O recorte temporal (1889-1891) remete o trabalho ao período do primeiro governo da república, chamado de governo provisório, que teve como Presidente, o Marechal Deodoro da Fonseca. O trabalho foi dividido em três capítulos: o primeiro ressalta o contexto do surgimento do pensamento positivista por intermédio da atuação de seu mentor Augusto Comte no debate intelectual da França. A partir disso, destacam-se aspectos que servem para esclarecer a cisão entre positivistas ortodoxos e heterodoxos e posteriormente, como as idéias positivistas se espalharam no contexto brasileiro. No mesmo capítulo, foi ressaltado ainda, o surgimento da Igreja Positivista do Brasil, as trajetórias de Miguel Lemos e Raimundo Teixeira Mendes até assumirem a direção e vice-direção do Apostolado. No segundo foi apresentada a ação política do Apostolado na tentativa de encaminhar o governo provisório para um regime político de ditadura definitiva. Tendo seu projeto político fracassado, o grupo passou a defender o cumprimento de artigos da constituição de 1891, que por diferentes motivos tivessem aspectos que se assemelhavam com a política tida pelo Apostolado como adequada. No terceiro foi mostrada a influência do positivismo em diferentes temas importantes no Brasil naquele momento, como, ensino, separação entre Estado e Igreja e movimento trabalhista. A persistência do lema positivista ordem e progresso na bandeira nacional até hoje, está entre os símbolos desta militância ortodoxa. Os membros do Apostolado Positivista não tiveram seu projeto de ditadura sacramentado apesar do forte influência da doutrina positivista no Brasil por dois aspectos, o primeiro por seguirem a recomendação de Comte de negar cargos políticos, o segundo pela doutrina positivista não ser orgânica a oligarquia cafeeira que iria nortear as bases de estruturação do país.

Use of endoparasitic helminths as tags in delineating stocks of American plaice (Hippoglossoides platessoides) from the southern Gulf of St. Lawrence and Cape Breton Shelf

Endoparasitic helminths were inventoried in 483 American plaice (Hippoglossoides platessoides) collected from the southern Gulf of St. Lawrence, NAFO (North Atlantic Fisheries Organization) division 4T, and Cape Breton Shelf (NAFO subdivision 4Vn) in September 2004 and May 2003, respectively. Forward stepwise discriminant function analysis (DFA) of the 4T samples indicated that abundances of the acanthocephalans Echinorhynchus gadi and Corynosoma strumosum were significant in the classification of plaice to western or eastern 4T. Cross validation yielded a correct classification rate of 79% overall, thereby supporting the findings of earlier mark-recapture studies which have indicated that 4T plaice comprise two discrete stocks: a western and an eastern stock. Further analyses including 4Vn samples, however, indicated that endoparasitic helminths may have little value as tags in the classification of plaice overwintering in Laurentian Channel waters of the Cabot Strait and Cape Breton Shelf, where mixing of 4T and 4Vn fish may occur.

The relationship between smolt and postsmolt growth for Atlantic salmon (Salmo salar) in the Gulf of St. Lawrence

The interaction of ocean climate and growth conditions during the postsmolt phase is emerging as the primary hypothesis to explain patterns of adult recruitment for individual stocks and stock complexes of Atlantic salmon (Salmo salar). Friedland et al. (1993) first reported that contrast in sea surface temperature (SST) conditions during spring appeared to be related to recruitment of the European stock complex. This hypothesis was further supported by the relationship between cohort specific patterns of recruitment for two index stocks and regional scale SST (Friedland et al., 1998). One of the index stocks, the North Esk of Scotland, was shown to have a pattern of postsmolt growth that was positively correlated with survival, indicating that growth during the postsmolt year controls survival and recruitment (Friedland et al., 2000). A similar scenario is emerging for the North American stock complex where contrast in ocean conditions during spring in the postsmolt migration corridors was associated with the recruitment pattern of the stock complex (Friedland et al., 2003a, 2003b). The accumulation of additional data on the postsmolt growth response of both stock complexes will contribute to a better understanding of the recruitment process in Atlantic salmon.

Vozes da reação: Atuação católica e laicização do Estado Brasileiro (1890 1891)

O objetivo desta dissertação é analisar a atuação de diferentes agentes da Igreja Católica para reverter a situação de desprestígio que o Governo Provisório tentou lhe impor, ao instaurar o Estado laico no Brasil. São analisado o jornal O Apóstolo, órgão da imprensa católica, documentos oficiais, como a Pastoral coletiva do episcopado de 1890 e as reclamações dirigidas pelos bispos às autoridades republicanas, e a atuação destacada de deputados e senadores defendendo no congresso constituinte de 1890-1891 os interesses da Igreja Católica. Desta forma, procuraremos demonstrar que a atuação integrada dos diversos agentes interferiu nos planos de laicização do governo, tornando as leis daquele período menos prejudiciais à Igreja do que inicialmente se projetara, o que levou à uma acomodação de interesses entre esta e governo.

Letter and Recollections of Alexander Agassiz: The 1891 Albatross Expedition

Presented here is another in the list of historic accounts of iconic research cruises of the USFC Steamer Albatross, this a reminiscence of the renowned scientist Alexander Agassiz edited by his son G. R. Agassiz, a chapter from the volume “Letters and Recollections of Alexander Agassiz,” published in 1913. Agassiz made three major cruises in the Albatross in 1891, 1899–1900, and 1904–05, adding greatly to the world’s store of specimens and knowledge of thalasography, his favored term for oceangraphy, and specifically of the Pacific Ocean. Having made important cruises and studies with the Blake in the Caribbean, he sought to do comparable research in the Pacific. His opportunity came in 1890, and with the consent of President Benjamin Harrison, he took charge of this Albatross research cruise, paying much of the expense himself. In contrast with the other ships he had been on, he found the laboratories, equipment, and furnishings to be comparatively luxurious and extremely well appointed for his work. Further, the Albatross was then captained by Lieutenant Commander Zera Luther Tanner who seemed to take as much interest in the oceanographic research as did the scientists, and Agassiz appreciated working with him, too. Little of the original text has been altered, and readers are cautioned that some of the views expressed may reflect unfortunate prejudices of that era toward individuals, nationalities, etc.

Um Gavroche entre a política e a sociedade: teatro de Arthur Azevedo (1891-1898)

Arthur Azevedo viveu uma época de mudanças. Nascido em São Luís do Maranhão, em 7 de julho de 1855, na Corte, como tantos outros jovens provincianos daquela época. No Rio de Janeiro, foi jornalista, escritor, funcionário público e destacado autor teatral. Testemunhou a passagem do Império à República, fazendo desse conjunto de acontecimentos, matéria e cenário para suas crônicas, contos e peças teatrais, em especial, em suas Revistas de Ano. Partindo do conceito de cultura política, tal como foi formulado por Serge Bernstein, pretende-se analisar a produção de Arthur nos anos subseqüentes à mudança do regime, à luz do contexto social e teatral experimentado pelo autor, articulando suas escolhas políticas e a cultura da época à obra por ele deixada.

Movement of American lobster (Homarus americanus) in the southwestern Gulf of St. Lawrence

A total of 42,445 American lobsters (Homarus americanus) were tagged in thirty-one sites throughout the southwestern Gulf of St. Lawrence between 1980 and 1997. Results from the recapture of 8503 tagged lobsters showed small distances traveled between the release and the recapture position for animals ranging in size from 51 to 152 mm carapace length. The average distance traveled ranged from 2 km in parts of Baie des Chaleurs and western Cape Breton to 19 km in central Northumberland Strait. Lobsters moved generally along the shore (93% of the dispersion was in areas between the shore and the 20-m bathymetric contour). As a result, lobsters traveled longer distances in sites characterized by a gradually sloping bottom where the distance between the shore and the 20-m contour line was extensive in contrast to areas characterized by rapidly changing depths and by a relatively small amount of habitat shallower than 20 m. In the majority of sites (14 of 19) there was no significant difference between males and females in the average distance they traveled. In four of the five sites females moved farther than males. In general, the average distance traveled by berried females was shorter than that traveled by males or nonberried females. No relationship was observed between the distance traveled and the size of the animal. There was no strong evidence of a relationship between the average distance traveled and the number of days at liberty. In general, lobsters in the southwestern Gulf of St. Lawrence traveled short distances and dispersion was restricted to the nearshore habitat. Further, the distance traveled was not correlated to size, sex, or years at large. These findings show that there is little interaction between American lobsters from different fishing areas at the benthic level and that American lobster movements should have minimal consequences for management of the species in the southwestern Gulf of St. Lawrence.
