    Understanding networks of biological interactions is essential to all life sciences. Nowadays, a large amount of biological information is archived in diverse resources that often contain complementary information. Scientists have to search various data repositories in order to reconstruct, understand and speculate on the steps that lead to specific phenomena. The amount of digitalised interaction data has grown to such an extent that it is now advisable to integrate different kinds of data through computational means. Bioinformatics can offer tools and strategies to manipulate such information automatically. In order to address the need of integrating and retrieving structured protein interaction data, I implemented a new resource called mentha, which merges the data archived in different repositories in order to assemble large networks of protein interactions. This resource has low data redundancy and it assigns a reliability score to each interaction. mentha can be seen as a workbench to assemble custom protein-protein interaction networks. Furthermore, I contributed to the development of a new resource that archives manually curated signalling information. I investigated the possibility of exploiting the information contained in mentha to assemble signalling networks. I analysed strategies to automatically link proteins of interest with other relevant proteins in order to create a backbone to build graph dynamical systems that can represent biological signalling networks. I conclude that manually curated signalling information can be integrated with information inferred from interactomes where signal direction can be predicted using orientation algorithms, while signal effect can be derived from RNA interference screenings. Finally, I analysed the resulting biological models as graph dynamical systems. I transformed the topology of a signed oriented biological network into transition boolean functions and, using boolean formalism, I analysed dynamical networks to simulate biological behaviours

    Orizzonti mantovani. Spunti e dinamiche paesaggistiche ne L'Illustrissimo di Alberto Cantoni

    No full text
    In the literary production of Alberto Cantoni, short story writer and novelist between the nineteenth and twentieth centuries, the novel L'Illustrissimo is highly important both because it is the last publication of the author, from Pomponesco, a small town a few kilometers south of Mantua, both because it summarizes in a single text the different nuances and different directions that his writing has taken over the course of his literary career, also due to a writing and processing time that embraces the entire span of years of his career itself. In the foreground, in addition to the numerous and brilliant characters, one of the protagonists is the Mantuan landscape which, not a simple background, becomes a true literary parameter which in different and significant ways affects the purposes and mechanisms of the novel

    mentha: a resource for browsing integrated protein-interaction networks

    No full text
    About mentha mentha archives evidence collected from different sources and presents these data in a complete and comprehensive way. Its data comes from manually curated protein-protein interaction databases that have adhered to the IMEx consortium. The aggregated data forms an interactome which includes many organisms. mentha is a resource that offers a series of tools to analyse selected proteins in the context of a network of interactions. Protein interaction databases archive protein-protein interaction (PPI) information from published articles. However, no database alone has sufficient literature coverage to offer a complete resource to investigate "the interactome". mentha's approach generates every week a consistent interactome (graph). Most importantly, the procedure assigns to each interaction a reliability score that takes into account all the supporting evidence. mentha offers eight interactomes (Homo sapiens, Arabidopsis thaliana, Caenorhabditis elegans, Drosophila melanogaster, Escherichia coli K12, Mus musculus, Rattus norvegicus, Saccharomyces cerevisiae) plus a global netowrk that comprises every organism, including those not mentioned. The website and the graphical application are designed to make the data stored in mentha accessible and analysable to all users

    O duplo significado do sentir e do pensar nas obras de Alberto Caeiro e Descartes

    Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em LiteraturaA pretensão desta dissertação intitulada O duplo significado do sentir e do pensar nas obras de Alberto Caeiro e Descartes é investigar a relação entre o sentir e o puro pensar, usando como referência a poesia O Guardador de Rebanhos, de Alberto Caeiro, que apresenta de forma evidente o tema; e como este assunto é tratado nas Meditações Metafísicas de René Descartes, também de forma claramente visível. Podemos perceber em ambos os autores, uma diplopia, uma espécie de duplo olhar sobre a relação sentir e puro pensar. No primeiro capítulo vou falar sobre a tese do duplo olhar de Descartes, a respeito da relação sentir e puro pensar na leitura de Merleau-Ponty, salientando a visão de natureza. No segundo capítulo, parto da leitura das três primeiras Meditações Metafísicas para caracterizar a tensão que se pode verificar entre Descartes e Alberto Caeiro quando se referem ao puro pensar. O foco principal de Descartes, nas três primeiras Meditações, é o pensar puro, e neste ponto Alberto Caeiro critica o pensar puro. No terceiro capítulo, analisando as três últimas Meditações, percebe-se que há uma virada no pensamento de Descartes, no qual o autor inverte seu ponto de vista, aproximando-se da idéia de Alberto Caeiro. No quarto capítulo, mostrarei a leitura que outros autores fazem acerca do sentir e do pensar na obra de Alberto Caeiro, mostrando que assim como Descartes, este também ostenta uma diplopia, não do sentir, mas do pensar. The pretension of this work entitled O duplo significado do sentir e do pensar nas obras de Alberto Caeiro e Descartes is to investigate the relationship between the feeling and the pure thinking, using as reference the poetry O Guardador de Rebanhos, by Alberto Caeiro, that presents in an evident way this theme; and as this subject is treated in René Descartes' Metaphysical Meditations, also in a clearly visible way. It is possible to notice in both authors, the diplopy, a sort of double look about the relationship between feeling and pure thinking. The thesis about Descartes'double look regarding the relation of feeling and pure thinking, in Merleau-Ponty reading, pointing out the nature vision, will be treated in the first chapter. In the second chapter, I start from the reading of the first three Metaphysical Meditations to characterize the tension that can be verified between Descartes and Alberto Caeiro when they refer to the pure thinking. Descartes' main focus in the first three Meditations is pure thinking and, in this point, Alberto Caeiro criticizes pure thinking. In the third chapter, analyzing the last three Meditations, it is possible to notice that there is an alteration in Descartes' thought, in which the author inverts his point of view, approaching of Alberto Caeiro's idea. In the fourth chapter, I will show the reading that other authors do concerning feeling and thinking in Alberto Caeiro's work, showing that as well as Descartes, this also shows a diplopy, not of feeling, but of thinking

    Lobbying for change as a new theory and practice of active citizenship: author interview with Alberto Alemanno

    No full text
    Do you believe that lobbying is a vehicle for representing the interests of some rather than all, meaning its actors can never be a force for good? Alberto Alemanno, author of Lobbying for Change: Find Your Voice to Create a Better Society, might convince you of the contrary. This interview with Barbara Aubin, LSE Public Affairs, reflects on the importance of engaging with our political representatives, holding them accountable and lobbying for the causes we deeply care about as fundamental elements of a healthy democracy
