O diagnóstico da hanseníase neural pura baseia-se em dados clínicos e laboratoriais do paciente, incluindo a histopatologia de espécimes de biópsia de nervo e detecção de DNA de Mycobacterium leprae (M. leprae) pelo PCR. Como o exame histopatológico e a técnica PCR podem não ser suficientes para confirmar o diagnóstico, a imunomarcação de lipoarabinomanana (LAM) e/ou Glicolipídio fenólico 1 (PGL1) - componentes de parede celular de M. leprae foi utilizada na primeira etapa deste estudo, na tentativa de detectar qualquer presença vestigial do M. leprae em amostras de nervo sem bacilos. Além disso, sabe-se que a lesão do nervo na hanseníase pode diretamente ser induzida pelo M. leprae nos estágios iniciais da infecção, no entanto, os mecanismos imunomediados adicionam severidade ao comprometimento da função neural em períodos sintomáticos da doença. Este estudo investigou também a expressão imuno-histoquímica de marcadores envolvidos nos mecanismos de patogenicidade do dano ao nervo na hanseníase. Os imunomarcadores selecionados foram: quimiocinas CXCL10, CCL2, CD3, CD4, CD8, CD45RA, CD45RO, CD68, HLA-DR, e metaloproteinases 2 e 9. O estudo foi desenvolvido em espécimes de biópsias congeladas de nervo coletados de pacientes com HNP (n=23 / 6 BAAR+ e 17 BAAR - PCR +) e pacientes diagnosticados com outras neuropatias (n=5) utilizados como controle. Todas as amostras foram criosseccionadas e submetidas à imunoperoxidase. Os resultados iniciais demonstraram que as 6 amostras de nervos BAAR+ são LAM+/PGL1+. Já entre as 17 amostras de nervos BAAR-, 8 são LAM+ e/ou PGL1+. Nas 17 amostras de nervos BAAR-PCR+, apenas 7 tiveram resultados LAM+ e/ou PGL1+. A detecção de imunorreatividade para LAM e PGL1 nas amostras de nervo do grupo HNP contribuiu para a maior eficiência diagnóstica na ausência recursos a diagnósticos moleculares. Os resultados da segunda parte deste estudo mostraram que foram encontradas imunoreatividade para CXCL10, CCL2, MMP2 e MMP9 nos nervos da hanseníase, mas não em amostras de nervos com outras neuropatias. Além disso, essa imunomarcação foi encontrada predominantemente em células de Schwann e em macrófagos da população celular inflamatória nos nervos HNP. Os outros marcadores de ativação imunológica foram encontrados em leucócitos (linfócitos T e macrófagos) do infiltrado inflamatório encontrados nos nervos. A expressão de todos os marcadores, exceto CXCL10, apresentou associação com a fibrose, no entanto, apenas a CCL2, independentemente dos outros imunomarcadores, estava associada a esse excessivo depósito de matriz extracelular. Nenhuma diferença na frequência da imunomarcação foi detectada entre os subgrupos BAAR+ e BAAR-, exceção feita apenas às células CD68+ e HLA-DR+, que apresentaram discreta diferença entre os grupos BAAR + e BAAR- com granuloma epitelioide. A expressão de MMP9 associada com fibrose é consistente com os resultados anteriores do grupo de pesquisa. Estes resultados indicam que as quimiocinas CCL2 e CXCL10 não são determinantes para o estabelecimento das lesões com ou sem bacilos nos em nervo em estágios avançados da doença, entretanto, a CCL2 está associada com o recrutamento de macrófagos e com o desenvolvimento da fibrose do nervo na lesão neural da hanseníase.

Charles Henry Gilbert (1859-1928) was a pioneering ichthyologist who made major contributions to the study of fishes of the American West. As chairman of the Department ofZoology at Leland Stanford Junior University in Palo Alto, Calif., during 1891-1925, Gilbert was extremely devoted to his work and showed little patience with those ofa different mindset. While serving as Naturalist-in-Charge of the U.S. Fish Commission Steamer Albatross during her exploratory expedition to the Hawaiian Islands in 1902, Gilbert engaged in an acrimonious feud with the ship's captain, Chauncey Thomas, Jr. (1850-1919), U.S.N., over what Gilbert perceived to be an inadequate effort by the captain. This essay focuses on the conflict between two strong figures, each operatingf rom different world views, and each vying for authority. Despite the difficulties these two men faced, the voyage of the Albatross in 1902 must be considered a success, as reflected by the extensive biological samples collected, the many new species of animals discovered, and the resulting publication of important scientific papers.

A Escola Moderna n.1 (São Paulo), sob a direção do professor libertário João Penteado, ofereceu uma alternativa de formação para os filhos da classe trabalhadora, inspirando-se na Pedagogia Libertária que, desde os primeiros debates da Internacional dos Trabalhadores até as experiências educacionais de Paul Robin, inseriu a luta de classes no espaço da escola. Assim, promoveu a interface entre educação e revolução social com base nos conceitos de Demopedia e Instrução Integral, desenvolvidos respectivamente por Pierre-Joseph Proudhon e Mikhail Bakunin. O presente estudo pretende desvelar como o espaço da Escola Moderna se converteu em ação revolucionária dos sindicatos operários, colaborando para os objetivos dos anarquistas que elegeram o sindicalismo revolucionário como a tática mais adequada para o estabelecimento da sociedade livre com a qual sonharam. Deste modo, entre os anos de 1912 a 1919, quando foi sumariamente fechada pelo Departamento de Instrução Pública do Estado, a Escola Moderna promoveu a ação direta e o mutualismo entre seus estudantes, tanto para que contribuíssem com o futuro da classe trabalhadora, de acordo com suas necessidades e conforme suas condições, como também para que os organismos de classe ultrapassassem as lutas mais imediatas.

Este trabalho tem por objetivo compreender o processo que levou ao fim da escravidão no Ceará entre os anos de 1870 e 1888 partindo dos discursos dos políticos cearenses na Assembleia Legislativa Provincial do Ceará e na Câmara Geral dos Deputados. Tomar-se-ão por base, aqui, os anais da citada Assembleia Legislativa e os Anais da Câmara dos Deputados, observando, nas discussões do Parlamento Imperial, os posicionamentos da bancada cearense. A ideia da pesquisa é identificar e analisar os projetos elaborados com o objetivo de resolver o problema da escravidão no Brasil, atentando para os argumentos utilizados pelos políticos cearenses e identificando os fundamentos explicativos para a necessidade de pôr fim à escravidão no Ceará. A análise desses discursos permitirá uma melhor compreensão da forma como a movimentação abolicionista/emancipacionista no Ceará foi percebida pelos políticos e ajudará a entender a construção do Ceará como exemplo de patriotismo, o que ocorre paralelamente a um processo de justificação do fim da escravidão que, em última instância, construiu uma determinada representação sobre o Ceará e os cearenses.

Given the economic and social importance of agriculture in the early years of the Irish Free State, it is surprising that the development of organisations representing farmers has not received the attention it deserves from historians. While the issues of government agricultural policy and the land question have been extensively studied in the historiography, the autonomous response by farmers to agricultural policies and the detailed study of the farmers’ organisations has simply been ignored in spite of the existence of a range of relevant primary sources. Farmers’ organisations have only received cursory treatment in these studies; they have been presented as passive spectators, responding in a Pavlovian manner to outside events. The existing historiography has only studied farmers’ organisations during periods when they impinged on national politics, epecially during the War of Independence and the Economic War. Therefore chronological gaps exist which has led to much misinterpretation of farmers’ activities. This thesis will redress this imbalance by studying the formation and continuous development of farmers’ organisations within the twenty-six county area and the reaction of farmers to changing government agricultural policies, over the period 1919 to 1936. The period under review entailed many attempts by farmers to form representative organisations and encompassed differing policy regimes. The thesis will open in 1919, when the first national organisation representing farmers, the Irish Farmers’ Union, was formed. In 1922, the union established the Farmers’ Party. By the mid- 1920’s, a number of protectionist agricultural associations had been formed. While the Farmers’ Party was eventually absorbed by Cumann na nGaedheal, local associations of independent farmers occupied the resultant vacuum and contested the 1932 election. These organisations formed the nucleus of a new national organisation; the National Farmers’ and Ratepayers’ League. The agricultural crisis caused by both the Great Depression and the Economic War facilitated the expansion of the league. The league formed a political party, the Centre Party, to contest the 1933 election. While the Centre Party was absorbed by the newly-formed Fine Gael, activists from the former farmer organisations led the campaign against the payment of annuities and rates. Many of them continued this campaign after 1934, when the Fine Gael leadership opposed the violent resistance to the collection of annuities. New farmer organisations were formed to co-ordinate this campaign which continued until 1936, the closing point of the thesis.

The turn of the 20th century marked an ascendancy of the Franco-Belgian school of composers. French composers were inspired by the great German composers of the Romantic era, and they created their own defined national style that emerged toward the end of the 19th century. The Franco-Belgian composers’ special emphasis on tone, timbre and color encouraged a more individual, personally interpretative approach. These devices underscore the importance and influence a performer can have on the outcome of a piece. I researched the relationship between composers and violinists at a time when the Franco-Belgian style developed and flourished. The Franco-Belgian school of violin playing emerged from the Paris and Brussels conservatories as well as the symbiotic relationship between the performers and composers. Three recitals in collaboration with pianist David Ballena, which comprise this dissertation project, were performed at the University of Maryland. Each recital featured music for violin and piano from 1870 through 1930. The repertoire was chosen to reflect a performer’s influence on a composer. I examined specific composer/performer relationships that helped shape the birth of a newly defined “French” style of playing. My research focused on the stylistic interactions composers, such as César Franck, his disciple Guillaume Lekeu had with the leading prominent Belgian violinist Eugène Ysaye and between Maurice Ravel and the Hungarian violinist Jelly d’Aranyi. I also looked into the personal relationship between friends who inspired each other: Gabriel Fauré and Paul Viardot, Edouard Lalo and Pablo de Sarasate, Claude Debussy and Arthur Hartmann, and the young Lili Boulanger and Yvonne Astruc. Furthermore, I looked into the unfulfilled love between Maurice Ravel and Hélène Jourdan-Morhange, as well as the marriage of Olivier Messiaen with Claire Delbos, both relationships resulting in masterpieces for violin that have remained a part of the standard violin repertoire. My research led me to understand what type of violin playing each composer had in mind while composing, all of which led me to understand the importance a performer has in preserving national styles. The recitals were recorded on compact discs and archived within the Digital Repository at the University of Maryland (DRUM).

The book has been described by various Irish historians as "the definitive treatment of that most peculiar institution--the Ulster Custom--and its tangled relationship with irish land and politics" (Liam Kennedy), "a brilliantly reconceptualised sketch of the Irish land question" (David Miller). "All previous discussion," according to another reviewer, "must take second place to Dowling's exhaustive survey, which draws on the whole range of surviving estate records to examine the theory and practice of tenant right across three centuries" (Sean Connolly).
