La ricerca affronta il rapporto tra il Partito comunista italiano e le organizzazioni della sinistra extraparlamentare nate nel biennio 1968-1969. Sulla base di documentazione d’archivio e fonti a stampa, vengono ricostruite ed analizzate le relazioni tra questi due soggetti nel periodo compreso tra la fine degli anni Sessanta e la metà del decennio successivo, quando i principali gruppi politici della sinistra extraparlamentare si dotarono di una struttura organizzativa più stabile che segnava una discontinuità con l’esperienza precedente. Nel corso della prima metà degli anni Settanta, i rapporti tra il PCI e queste organizzazioni furono complessi e talvolta contraddittori. Il conflitto si consumò prevalentemente sulla reciproca pretesa di possedere l’esclusiva rappresentanza politica del fermento sociale che attraversava il paese in quegli anni: il PCI rappresentando se stesso come l’unica forza politica capace di mediare tra movimenti sociali e istituzioni; i gruppi della sinistra parlamentare come «avanguardie» di un irrealizzabile progetto «rivoluzionario».

The studies conducted during my Phd thesis were focused on two different directions: 1. In one case we tried to face some long standing problems of the asymmetric aminocatalysis as the activation of encumbered carbonyl compounds and the control of the diastereoisomeric ratio in the diastero- and enantioselective construction of all carbon substituted quaternary stereocenters adjacent a tertiary one. In this section (Challenges) was described the asymmetric aziridination of ,-unsaturated ketones, the activation of ,-unsaturated -branched aldehydes and the Michael addition of oxindoles to enals and enones. For the activation via iminium ion formation of sterically demanding substrates, as ,-unsaturated ketones and ,-unsaturated -branched aldehydes, we exploited a chiral primary amine in order to overcome the problem of the iminium ion formation between the catalyst and encumbered carbonylic componds. For the control of diastereoisomeric ratio in the diastero- and enantioselective construction of all carbon substituted quaternary stereocenters adjacent a tertiary one we envisaged that a suitable strategy was the Michael addition to 3 substituted oxindoles to enals activated via LUMO-lowering catalysis. In this synthetic protocol we designed a new bifunctional catalyst with an amine moiety for activate the aldehyde and a tioureidic fragment for direct the approach of the oxindole. This part of the thesis (Challenges) could be considered pure basic research, where the solution of the synthetic problem was the goal itself of the research. 2. In the other hand (Molecules) we applied our knowledge about the carbonylic compounds activation and about cascade reaction to the synthesis of three new classes of spirooxindole in enantiopure form. The construction of libraries of these bioactive compounds represented a scientific bridge between medicinal chemistry or biology and the asymmetric catalysis.

Oggetto della ricerca è l’accertamento dell’esistenza, nonché la definizione, della strategia dall’UE in materia di controversie commerciali aventi ad oggetto l’interpretazione e l’applicazione di norme facenti capo agli Accordi OMC in materia di misure sanitarie e di barriere tecniche al commercio. Nella prima parte della tesi, si ricostruiscono gli obbiettivi perseguiti dall’UE in materia di controversie SPS e TBT. In questo contesto, un’importanza di primo piano è attribuita alla difesa dell’autonomia regolamentare dell’Unione. Ad essa si riconduce la prassi UE finalizzata a prevenire il sorgere di controversie sul piano bilaterale attraverso la conclusione di accordi di mutuo riconoscimento, la cui portata ella sottolinea essere tuttavia limitata. L’analisi di cinque controversie sorte in ambito OMC di cui l’Unione è o è stata parte convenuta e che si fondano su presunte o accertate violazioni delle norme facenti capo ai due accordi menzionati consente di classificare gli argomenti giuridici avanzati dall’Unione nel contesto di tali controversie. Nella seconda parte della ricerca, la candidata identifica i mezzi a servizio della strategia UE, in primo luogo, attraverso l’analisi del quadro giuridico relativo alla partecipazione dell’Unione e degli Stati Membri al sistema OMC di risoluzione delle controversie; in secondo luogo, attraverso lo studio, da un lato, dello status delle norme OMC nell’ordinamento UE e, dall’altro, degli effetti delle pronunce dell’Organo di Risoluzione delle Controversie e della questione della responsabilità dell’Unione per violazione del diritto OMC. Sulla base del lavoro di ricerca svolto, si conclude che una strategia dell’UE esiste nella misura in cui l’Unione persegue l’obbiettivo di preservare la propria autonomia regolamentare attraverso, anche se non esclusivamente, gli strumenti afferenti all’ordine giuridico interno analizzati nella seconda parte. La candidata conclude altresì che la riforma del diritto delle relazioni esterne operata dal Trattato di Lisbona può indurre un cambiamento di tale strategia.

The aim of the dissertation was to test the feasibility of a new psychotherapeutic protocol for treating children and adolescents with mood and anxiety disorders: Child-Well-Being Therapy (CWBT). It originates from adult Well-Being Therapy protocol (WBT) and represents a conceptual innovation for treating affective disorders. WBT is based on the multidimensional model of well-being postulated by Ryff (eudaimonic perspective), in sequential combination with cognitive-behavioral therapy (CBT). Results showed that eudaimonic well-being was impaired in children with affective disorders in comparison with matched healthy students. A first open investigation aimed at exploring the feasibility of a 8-session CWBT protocol in a group of children with emotional and behavioural disorders has been implemented. Data showed how CWBT resulted associated to symptoms reduction, together with the decrease of externalizing problems, maintained at 1-year follow-up. CWBT triggered also an improvement in psychological well-being as well as an increasing flourishing trajectory over time. Subsequently, a modified and extended version of CWBT (12-sessions) has been developed and then tested in a controlled study with 34 patients (8 to 16 years) affected by mood and anxiety disorders. They were consecutively randomized into 3 different groups: CWBT, CBT, 6-month waiting list (WL). Both treatments resulted effective in decreasing distress and in improving well-being. Moreover, CWBT was associated with higher improvement in anxiety and showed a greater recovery rate (83%) than CBT (54%). Both groups maintained beneficial effects and CWBT group displayed a lower level of distress as well as a higher positive trend in well-being scores over time. Findings need to be interpret with caution, because of study limitations, however important clinical implications emerged. Further investigations should determine whether the sequential integration of well-being and symptom-oriented strategies could play an important role in children and adolescents’ psychotherapeutic options, fostering a successful adaptation to adversities during the growth process.

In this thesis is described the design and synthesis of potential agents for the treatment of the multifactorial Alzheimer’s disease (AD). Our multi-target approach was to consider cannabinoid system involved in AD, together with classic targets. In the first project, designed modifications were performed on lead molecule in order to increase potency and obtain balanced activities on fatty acid amide hydrolase and cholinesterases. A small library of compounds was synthesized and biological results showed increased inhibitory activity (nanomolar range) related to selected target. The second project was focused on the benzofuran framework, a privileged structure being a common moiety found in many biologically active natural products and therapeutics. Hybrid molecules were designed and synthesized, focusing on the inhibition of cholinesterases, Aβ aggregation, FAAH and on the interaction with CB receptors. Preliminary results showed that several compounds are potent CB ligands, in particular the high affinity for CB2 receptors, could open new opportunities to modulate neuroinflammation. The third and the fourth project were carried out at the IMS, Aberdeen, under the supervision of Prof. Matteo Zanda. The role of the cannabinoid system in the brain is still largely unexplored and the relationship between the CB1 receptors functional modification, density and distribution and the onset of a pathological state is not well understood. For this reasons, Rimonabant analogues suitable as radioligands were synthesized. The latter, through PET, could provide reliable measurements of density and distribution of CB1 receptors in the brain. In the fifth project, in collaboration with CHyM of York, the goal was to develop arginine analogues that are target specific due to their exclusively location into NOS enzymes and could work as MRI contrasting agents. Synthesized analogues could be suitable substrate for the transfer of polarization by p-H2 molecules through SABRE technique transforming MRI a more sensitive and faster technique.
