Pregnancies and oral contraceptive therapy in severe (homozygons) FXII deficiency: a study in 12 patients and review of the literature
No full textTwelve women with severe Factor XII (FXII) deficiency were under observation for an average period of about 16 years. During this time, these women had 19 pregnancies without any bleeding or thrombotic complications. The evaluation of the literature has shown that three patients manifested deep vein thrombosis during pregnancy. Five women also showed mild bleeding at delivery . The significance of these findings is not clear since thrombotic and bleeding complications may occur occasionally even in normal women. Five of our patients took oral contraceptive therapy during their fertile life for a variable period of time (2-10 years). No thrombosis was noted in any of these patients. From the scanty data gathered, in this respect, from the literature, it was shown that only three women with severe FXII deficiency took oral contraceptives and no thrombosis was noted. Altogether these results seem to indicate that the FXII deficiency does not play any significant role in the pathogenesis of bleeding and of thrombotic complications in pregnancy. However, the occurrence of deep vein thrombosis in 3 out of the 64 patients for whom sufficient data could be gathered indicates the need for further studies. This is more so if one considers that 3 out of the 6 cases of venous thromboses described altogether in the literature for females with severe FXII deficiency occurred during pregnancy or puerperium

Shannon Information Theory and Molecular Biology
No full textThe role and the contribution of Shannon Information Theory to the development of Molecular Biology has been the object of stimulating debates during the last thirty years. This seems to be connected with some semantic charms associated with the use of the word “information” in the biological context. Furthermore information itself, if viewed in a broader perspective, is far from being completely defined in a fashion that overcomes the technical level at which the classical Information Theory has been conceived. This review aims at building on the acknowledged contribution of Shannon Information Theory to Molecular Biology, so as to discover if it is only a technical tool to analyze DNA and proteinic sequences, or if it can rise, at least in perspective, to a higher role that exerts an influence on the construction of a suitable model for handling the genetic information in Molecular Biology
Innovative green methodologies for C-C, C-N and C-O bond forming reactions
No full textIn this PhD thesis it is presented the use of some Green Chemistry Tools (supercritical carbon dioxide, ionic liquids and dialkylcarbonates) for the set up of new green methodologies for C-C, C-N and C-O bond forming reactions. The following reactions have been investigated: the self-metathesis of 1-octene catalysed by supported Re oxide systems, carried out using dense CO2 as solvent; the Michael addition of nitroalkanes and beta-diketones to alpha,beta-unsaturated ketons catalyzed by task specific phosphonium based ionic liquids; the selective mono-hydroxyalkylation of anilines with glycerol carbonate catalysed by alkali metal exchanged faujasites; the selective bis-N-methylation of anilines carried by dimethylcarbonate prepared in situ via the transesterification of alkylene carbonate with methanol catalysed by alkali metal exchanged faujasites; the alkylation of primary aromatic amines with alkylene carbonates, catalysed by phosphonium based ionic liquids; the decarboxylation reaction of dialkyl carbonates catalyzed by different heterogeneous systems; the reaction of glycerol carbonate with phenol, in the presence of faujasites as catalysts.In questo lavoro di tesi è riportato l'impiego di alcuni strumenti della Green Chemistry (come la CO2, i liquidi ionici e i dialchilcarbonati) per la messa a punto di metodologie innovative a ridotto impatto ambientale per la formazione di legami C-C, C-N e C-O. Sono state investigate le seguenti reazioni: la metatesi dell'1-ottene catalizzata da sistemi a base di Re ossido, in presenza di CO2 densa come solvente; l'addizione di Michael di nitroalcani e beta-dichetoni a chetoni alfa,beta-insaturi catalizzata da liquidi ionici; la selettiva mono-idrossialchilazione di aniline con la glicerina carbonato, catalizzata da faujasiti; la selettiva bis-N-alchilazione di aniline da parte del dimetilcarbonato prodotto in situ via transesterificazione di carbonati ciclici con metanolo, catalizzata da faujasiti; l'alchilazione di aniline con carbonati ciclici catalizzata da liquidi ionici; la reazione di decarbossilazione dei dialchilcarbonati in presenza di diversi catalizzatori eterogenei; la reazione tra fenolo e glicerina carbonato catalizzata da faujasiti
