The aim of this study is to evaluate the effects of the pulsed electromagnetic fields (PEMFS) on pain relief and functional capacity of dogs with osteoarthritis by which a single centre study prospective clinical trial. PEMFs are non ionized, athermic and time varying electromagnetic fields that has been successfully used for the treatment of osteoarthritis in human thanks to their chondroprotective, antinflammatory and analgesic property. 20 dogs were treated with PEMFs , 3 times per week for a total of 20 sessions.We found beneficial effects on pain relief and lameness in the absence of adverse effect. The decrease of pain impacted positively on the health-dogs related quality of life and the grade of satisfaction of their owner was very high. The benefits were obvious at half therapy and lasted for a medium long time. This is the first published report concerning PEMFs treatment on canine osteoarthtitis. The result of this study proves that PEMFs is a non –invasive remedy, lacking in adverse effect , easy to employ and useful for controlling pain and inflammation associated with osteoarthritis.

The transformation of legislative processes in the Information society: from eLegislation to eParliament This research analyzes, by means of an interdisciplinary and comparative approach, the transformation of legislative processes produced by the introduction of new ICT technologies. The use of ICT in support of parliamentary activities is concerned with efficiency of parliamentary process and aims at more transparent procedures, improved access to documents, social participation and cooperation among institutions. With ICT Parliaments are now able to improve their efficiency and optimize their business; they can advance the dialogue with their citizen both, through the real access and the effective availability of information and, through new way of participation in the democratic process. Finally, sharing information, know-out, best practices and other records, Parliaments will be able to develop new information and knowledge and to strengthen the role and power of Institutions. Only through a global vision of the full process, re-thinking and develop rules and uniform standard and so implementing the new opportunities carrying out by ICT, it will be possible to put in practice concrete eParliament results. The Research goals are at least three: 1. To Analysed the legislative process and the ICT opportunities to understand the impact of the latter on the former. In particular to check up the problems that ICT can raise in relation of the constitutional principles ensuring the process itself. 2. To realized an abstract model representing the legislative process regardless of the form of government, chambers composition, legal system, etc. 3. To suggest standard, structural, linguistic and ontological, able to implement the new opportunities of sharing, cooperation and reuse among the many and various stakeholders of the democratic/legislative view.

La tesi analizza le fattispecie di recesso introdotte dalla riforma delle società di capitali del 2003. Particolare attenzione viene dedicata alle ipotesi legali di recesso e, fra queste, a quelle inderogabili, considerate “cuore” dell’istituto anche dopo la novella del 2003. Viene in particolare sottolineata la continuità fra la “vecchia” e la “nuova” disciplina dell’istituto e, sulla base anche di questo presupposto, si privilegiano interpretazioni che confinano l’operatività del diritto di recesso ai casi “estremi” in cui alla maggioranza assembleare è attribuito il potere di modificare in modo significativo lo statuto sociale. In questo contesto è dedicata particolare attenzione a due delle nuove fattispecie introdotte dalla riforma – il recesso per “modificazioni dello statuto concernenti i diritti di voto o di partecipazione” (art. 2437, comma 1, lett. g) c.c.) e il recesso ad nutum da società contratta a tempo indeterminato (art. 2437, comma 3 c.c.) – allo scopo di porre le basi, per quanto possibile, per un’interpretazione restrittiva delle stesse, che ne eviti un’incontrollata ed eccessivamente ampia applicazione.

Kafir Kala is a key-site to understand the historical dynamics of the Samarkand Region in the Early Middle Ages (5th - 8th centuries CE). The site is clearly associated with a Sogdian occupation, as both literature and archaeological research testify. But the chronological phase that follows the Sogdian period, as the Islamic occupation became stable, is still little known. Structures and finds (an hoard of 133 silver coins, in particular) clearly testify a new occupation of some parts of the citadel; and some rooms, dug in the northern side of it, present structures and materials connected with an Islamic activity. The study of material culture from these rooms, and from more ancient contexts, will help to understand the eventual continuity of traditions and the new productions. Besides the citadel, as a matter of fact, also some kilns have been dug, near the main site. Their material culture is very interesting because it represents an example of the typical Sogdian production (ceramics covered with white mica, and stamped). The work on the ceramic material has consisted in cataloguing and classifying all the diagnostics. Three main morphological classes have been individuated: cooking, coarse and table ware), and some other ones (lamps, ossuaries). A catalogue of the finds organized them in a typological system based on their morphology, function, fabric, and eventually decoration style. Crossing the stratigraphical data with information from this typological study, it has been possible to provide a chronological arrangement of the sites investigated by the italo-uzbek archaeological mission from 2001 to 2008.

Non può dirsi ancora raggiunta una completa, appagante e condivisa definizione di criminalità organizzata: eppure tale concetto viene ampiamente utilizzato, entrando nel linguaggio comune e –soprattutto- in quello normativo e giurisprudenziale. Attraverso il susseguirsi di numerosi interventi legislativi, abbiamo assistito alla progressiva elaborazione del c.d. doppio binario: di una normativa, cioè, ad hoc per i reati di criminalità organizzata, caratterizzata da un rilevante arretramento delle ordinarie soglie di garanzia previste dall’ordinamento giuridico. Alla luce di prioritarie esigenze di legalità si giustifica l’impellente necessità di giungere alla elaborazione di una precisa definizione di criminalità organizzata. A tale fine, nel corso del presente lavoro, sono stati esaminati i principali approcci definitori individuati a livello socio-criminologico, giurisprudenziale ed in ambito normativo, con particolare attenzione al diritto penale e processual-penalistico; si è inoltre proceduto all’analisi delle principali definizioni riscontrabili a livello comunitario ed internazionale.

Background: Intestinal fibrosis is a serious complication of IBD, with more than a third of Crohn’s disease (CD) patients developing a fibrostenosing phenotype with formation of strictures that will require surgical intervention. Remarkably, SAMP1/YitFc (SAMP) mice, a spontaneous model of CD, develop gut fibrosis; similar to IBD patients, the pathophysiology of SAMP fibrosis is unknown. IL-33 is a member of the IL-1 cytokine family and increased expression is associated with IBD. Emerging evidence suggests its potential role in liver and cutaneous fibrosis, as well as myofibroblast-associated colonic ulcerations . Aim: The aim of this study was to evaluate the role of IL-33 as a potential mediator of profibrotic events leading to intestinal fibrosis and possible stricture formation. Methods: A detailed histologic time course study, with collagen-specific Masson trichrome staining and IHC for ST2 (IL-33 receptor), was performed on SAMP and control AKR (parental strain) mice. qRT-PCR was done on full-thickness ilea for the profibrogenic genes, collagen (coll)-1, coll-3, connective tissue growth factor (CTGF) and insulin-like growth factor 1 (IGF-1). Exogenous IL-33 (33 μg/kg, i.p.) or vehicle was administered daily for 7d to SAMP and AKR mice (N=6/exp group), and ileal tissues evaluated as above. Finally, microarray analysis was performed on full-thickness ilea from SAMP and AKR mice, and IL-33 stimulated subepithelial myofibroblasts (SEMFs). Results: SAMP mice displayed ileal skip lesions with randomly distributed strictures, preceded by typical pre-stricture dilations of the ileum. Ileal wall was visibly thickened with hypertrophy of the serosa, muscularis mucosa, muscularis propria, within which intense collagen deposition was observed, and inflammatory infiltrates in segments showing strictures. Interestingly, intense ST2 staining was present within the inflamed lamina propria of SAMP, notably localized to SEMFs. Fibrosis was first observed at 20 wks, and reached its peak by 50 wks of age. mRNA expression of coll-1 (4.74±0.69-fold; P=0.001), coll-3 (4.92±1.05-fold; P=0.01), IGF1 (12.9±3.45; P=0.006), and CTGF (3.29±0.69; P=0.004) was dramatically elevated in SAMP vs. AKR ilea. IL-33 treatment of AKR mice induced a marked increase in muscle fiber/myofibroblast cellularity and hypertrophy of the muscularis propria (4.13±0.74-fold; P<0.0001), and mRNA expression of coll-1 (5.16±0.89-fold; P=0.0009), coll-3 (1.97±0.14-fold; P=0.01), IGF-1 (9.32±2.27-fold; P=0.004), and CTGF (1.43±0.31-fold; P=0.006) vs. vehicle controls. Microarray data from SAMP ilea and IL-33-treated SEMFs confirmed these trends, displaying a global increase in profibrogenic gene expression. Conclusion: These data suggest an important role for IL-33 in intestinal fibrosis, and may represent a potential target for the treatment of IBD-associated fibrosis and stricture formation.

Nel corso degli ultimi due decenni in particolare si è andata evidenziando a livello epatologico una entità definita oggi Non-alcoholic Fatty Liver Disease (NAFLD) che si è andata ad affiancare alle cause in precedenza conosciute, fino a risultare, attraverso il succedersi di riscontri scientifici, la causa prevalente di epatopatia, in particolare nei paesi occidentali e industrializzati. Negli stessi anni un'altra problematica clinica complessa che va sotto il nome di Sindrome Metabolica si è andata via via delineando attraverso le sue molteplici correlazioni con quelle che sono le cause di morbidità e mortalità prevalenti nella nostra realtà, dal diabete alla patologia cardiovascolare e non ultima alla NAFLD stessa. Scopo dello Studio in oggetto a questa tesi era proprio di rivalutare nel territorio italiano la prevalenza di epatopatia in particolare correlabile alla NAFLD e la sua associazione con la Sindrome Metabolica.

La dermoscopia, metodica non invasiva, di pratico utilizzo e a basso costo si è affermata negli ultimi anni come valido strumento per la diagnosi e il follow up delle lesioni cutanee pigmentate e non pigmentate. La presente ricerca è stata incentrata sullo studio dermoscopico dei nevi melanocitici a localizzazione palmo-plantare, acquisiti e congeniti, in età pediatrica: a questo scopo sono state analizzate le immagini dei nevi melanocitici acrali nei pazienti visitati c/o l’ambulatorio di Dermatologia Pediatrica del Policlinico Sant’Orsola Malpighi dal 2004 al 2011 per definire i principali pattern dermoscopici rilevati ed i cambiamenti osservati durante il follow up videodermatoscopico. Nella nostra casistica di immagini dermoscopiche pediatriche abbiamo notato un cambiamento rilevante (inteso come ogni modificazione rilevata tra il pattern demoscopico osservato al baseline e i successivi follow up) nell’88,6% dei pazienti ed in particolare abbiamo osservato come in un’alta percentuale di pazienti (80%), si sia verificato un vero e proprio impallidimento del nevo melanocitico e in un paziente è stata evidenziata totale regressione dopo un periodo di tempo di 36 mesi. E’ stato interessante notare come l’impallidimento della lesione melanocitaria si sia verificata per lo più in sedi sottoposte ad una sollecitazione meccanica cronica, come la pianta del piede e le dita (di mani e piedi), facendoci ipotizzare un ruolo del traumatismo cronico nelle modificazioni che avvengono nelle neoformazioni melanocitarie dei bambini in questa sede.
