Teorie e immagini del governo "misto" nel Cinquecento: i casi di Gasparo Contarini, Donato Giannotti, Paolo Paruta e Traiano Boccalini

This doctoral dissertation faces the debated topic of the traditions of Republicanism in the Modern Age assuming, as a point of view, the problem of the "mixed" government. The research therefore dwells upon the use of this model in Sixteenth-Century Italy, also in connection with the historical events of two standard Republics such as Florence and Venice. The work focuses on Donato Giannotti (1492-1573), Gasparo Contarini (1483-1542) and Paolo Paruta (1540-1598), as the main figures in order to reconstruct the debate on "mixed" constitution: in them, decisive in the attention paid to the peculiar structure of the Venetian Republic, the only of a certain dimension and power to survive after 1530. The research takes into account also the writings of Traiano Boccalini (1556-1613): he himself, though being involved in the same topics of debate, sets for some aspects his considerations in the framework of a new theme, that of Reason of State.

Il cane come modello animale spontaneo di patologie neoplastiche dell'uomo: ene Ataxia-Telangiectasia Mutated (ATM) Nnella predisposizione al cancro ed importanza dei riarrangimanti genici dei geni Ig/TCR per la diagnosi e prognosi delle malattie linfoproliferative

“Naturally occurring cancers in pet dogs and humans share many features, including histological appearance, tumour genetics, molecular targets, biological behaviour and response to conventional therapies. Studying dogs with cancer is likely to provide a valuable perspective that is distinct from that generated by the study of human or rodent cancers alone. The value of this opportunity has been increasingly recognized in the field of cancer research for the identification of cancer-associated genes, the study of environmental risk factors, understanding tumour biology and progression, and, perhaps most importantly, the evaluation and development of novel cancer therapeutics”.(Paoloni and Khanna, 2008) In last years, the author has investigated some molecular features of cancer in dogs. The Thesis is articulated in two main sections. In section 1, the preliminary results of a research project aimed at investigating the role of somatic mutations of Ataxia-Telangiectasia mutated (ATM) gene in predisposing to cancer in boxer dogs, are presented. The canine boxer breed may be considered an unique opportunity to disclose the role of ATM somatic mutation since boxer dogs are known to be dramatically susceptible to cancer and since they may be considered a closed gene pool. Furthermore, dogs share with human the some environment. Overall, the abovementioned features could be considered extremely useful for our purposes. In the section 2, the results of our studies aimed at setting up accurate and sensitive molecular assays for diagnosing and assessing minimal residual disease in lymphoproliferative disorders of dogs, are presented. The results of those molecular assay may be directly translated in the field of Veterinary practice as well as the may be used to improve our objective evaluation of new investigational drugs effectiveness in canine cancer trials.
