Differential stability of 2'F-ANA*RNA and ANA*RNA hybrid duplexes: roles of structure, pseudohydrogen bonding, hydration, ion uptake and flexibility
No full text14 pags., 7 figs., 3 tabs.Hybrids of RNA with arabinonucleic acids 2′F-ANA and ANA have very similar structures but strikingly different thermal stabilities. We now present a thorough study combining NMR and other biophysical methods together with state-of-the-art theoretical calculations on a fully modified 10-mer hybrid duplex. Comparison between the solution structure of 2′F-ANA•RNA and ANA•RNA hybrids indicates that the increased binding affinity of 2′F-ANA is related to several subtle differences, most importantly a favorable pseudohydrogen bond (2′F-purine H8) which contrasts with unfavorable 2′-OH-nucleobase steric interactions in the case of ANA. While both 2′F-ANA and ANA strands maintained conformations in the southern/eastern sugar pucker range, the 2′F-ANA strand's structure was more compatible with the A-like structure of a hybrid duplex. No dramatic differences are found in terms of relative hydration for the two hybrids, but the ANA•RNA duplex showed lower uptake of counterions than its 2′F-ANA•RNA counterpart. Finally, while the two hybrid duplexes are of similar rigidities, 2′F-ANA single strands may be more suitably preorganized for duplex formation. Thus the dramatically increased stability of 2′F-ANA•RNA and ANA•RNA duplexes is caused by differencesin at least four areas, of which structure and pseudohydrogen bonding are the most important. © The Author(s) 2010.

Representações da sexualidade na obra de Ana Saldanha
No full textMestrado em Línguas, Literaturas e CulturasA presente dissertação analisa as diferentes representações da sexualidade na obra literária para jovens de Ana Saldanha. A leitura analítica incide sobre as narrativas da autora que abordam a temática da sexualidade juvenil e as suas problemáticas, com o objetivo de estudar a forma como as mesmas contribuem para a construção da identidade pessoal e sexual do potencial recetor juvenil. Desta forma, pretende-se detetar os conflitos psicológicos dos protagonistas, os seus valores e problemas, assim como os novos valores, problemas e preocupações sociais que emergem das narrativas; compreender de que forma a autora exprime a sua capacidade em observar o quotidiano e as relações humanas; identificar os pilares em que se apoia o universo social em estudo (família, escola, grupo de amigos); enquadrar as personagens numa sociedade pós-industrial e de informação que exige ao adolescente uma superação de desafios e de novos problemas.This dissertation analyzes the different representations of sexuality in Ana Saldanha’s literary work for youth. The analytical reading focuses on the author's narratives that address the issue of teenage sexuality and its problems, aiming to study their contribution in the construction of personal and sexual identity of the potential juvenile receiver. Thus, it is intended to detect the psychological conflicts of the protagonists, their values and problems, as well as the new values, social concerns and problems that emerge from the narratives; understand how the author expresses her ability to observe daily life and human relations; identify the pillars on which relies the social universe under study (family, school, friends); framing the characters in a post-industrial and information society which requires the teenager to relentlessly surmount challenges and new problems
Viajantes ex-cêntricas nas histórias de Ana Miranda
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em Literatura.No conjunto das narrativas ficcionais da escritora brasileira Ana Miranda, a temática da viagem # considerada uma das mais férteis da literatura ocidental de todos os tempos # ocupa um espaço de centralidade, podendo até mesmo ser vista como o mais importante eixo de estruturação de suas obras. O estudo realizado pela presente tese tem por objetivo analisar o tratamento dado ao tema da viagem nos romances Desmundo, O retrato do rei, Dias & Dias e Amrik, evidenciando que por intermédio das narradora-viajantes # Oribela, Mariana, Feliciana e Amina # a autora promove um diálogo entre diferentes culturas, gêneros, etnias e gerações, ao mesmo tempo em que estabelece um profícuo diálogo com o passado em sua invariante problematização concernente aos limites e cruzamentos entre o discurso ficcional e os discursos narrativos extraliterários que o cercam, sobretudo o histórico e o biográfico. In the whole of Brazilian writer Ana Miranda#s fictional narrative, the travel thematic # considered one of the most fertile themes of the western literature of all times # occupies a central space, and can even been seen as the most important structuring axis of Miranda#s works. The aim of the present thesis is to analyze the treatment given to the travel subject in the novels Desmundo, O retrato do rei, Dias & Dias and Amrik, emphasizing that, through the traveling narrators, Oribela, Mariana, Feliciana and Amina, the author promotes a connection between different cultures, genders, ethnics and generations, at the same time that establishes a profitable dialogue with the past in her invariant problematization concerning the limits and crossings between the fictional and the extra-literary narrative discourses that surrounds it, mainly the historical and the biographic ones
