Identificazione e dosaggio di marcatori molecolari dell'endometriosi nel sangue periferico

Purpose: to quantify the mRNA levels of MMP-3, MMP-9, VEGF and Survivin in peripheral blood and the serum levels of CA-125, Ca19-9 in women with and without endometriosis and to investigate the performance of these markers to differentiate between deep and ovarian endometriosis. Methods: a case controls study enrolled a series of 60 patients. Twenty controls have been matched with 20 cases of ovarian and 20 cases of deep endometriosis. Univariable and multivariable performance of serum CA125 and CA19-9, mRNA for Survivin, MMP9, MMP3 and VEGF genes have been evaluated by means of ROC curves and logistic regression respectively. Results: No difference in markers concentration were detected between ovarian and deep endometriosis. In comparison with controls serum CA19 and CA125 yielded the better sensitivity followed by mRNA for Survivin gene (81.5%, 51.9% and 7.5% at 10% false positive rate respectively). Multivariable estimated odds of endometriosis yielded a sensitivity of 87% at the same false positive rate. Conclusions: A combination of serum and molecular markers could allow a better diagnosis of endometriosis.

Produzione di idrogeno mediante reforming ciclico dell'etanolo

This work deals with a study on the feasibility of a new process, aimed at the production of hydrogen from water and ethanol (a compound obtained starting from biomasses), with inherent separation of hydrogen from C-containing products. The strategy of the process includes a first step, during which a metal oxide is contacted with ethanol at high temperature; during this step, the metal oxide is reduced and the corresponding metallic form develops. During the second step, the reduced metal compound is contacted at high temperature with water, to produce molecular hydrogen and with formation of the original metal oxide. In overall, the combination of the two steps within the cycle process corresponds to ethanol reforming, where however COx and H2 are produced separately. Various mixed metal oxides were used as electrons and ionic oxygen carriers, all of them being characterized by the spinel (inverse) structure typical of Me ferrites: MeFe2O4 (Me=Co, Ni, Fe or Cu). The first step was investigated in depth; it was found that besides the generation of the expected CO, CO2 and H2O, the products of ethanol anaerobic oxidation, also a large amount of H2 and coke were produced. The latter is highly undesired, since it affects the second step, during which water is fed over the pre-reduced spinel at high temperature. The behavior of the different spinels was affected by the nature of the divalent metal cation; magnetite was the oxide showing the slower rate of reduction by ethanol, but on the other hand it was that one which could perform the entire cycle of the process more efficiently. Still the problem of coke formation remains the greater challenge to solve.

I Responsori della Settimana Santa del Ms 443 dell'Accademia Filarmonica di Bologna

La tesi è dedicata allo studio dei Responsori della Settimana Santa contenuti nel volume manoscritto Musica per la Settimana Santa conservato presso l’Accademia Filarmonica di di Bologna: (I-Baf FA1 443), che la tradizione storiografica fino ad alcuni anni fa attribuiva interamente ad Alessandro Scarlatti. Il volume raccoglie un ampio repertorio di brani musicali appartenenti a generi destinati ai periodi liturgici della Quaresima e del Triduo pasquale. Il lavoro è dedicato ai responsori considerati innanzitutto come progetto compositivo a sé stante e come fonte di rilievo nell’ambito della musica sacra e del genere responsoriale in particolare. Lo studio è suddiviso in due parti: la prima riguarda le ricerche codicologiche sul volume, del quale si riassume anche la storia con nuove ricerche sulla sua acquisizione da parte dell’Accademia Filarmonica. Viene poi esaminato il contesto storico-liturgico della musica per la Settimana Santa e si prendono in esame gli aspetti stilistici del repertorio responsoriale polifonico italiano dalla metà del ‘500 allla prima metà del ’700, in particolare nell’ambito del cosiddetto «stile osservato» del tempo. Nel terzo ed ultimo capitolo della prima parte vengono analizzati nella forma e nello stile i responsori del Ms 443 di Bologna, tenendo conto della teoria musicale e delle consuetudini contrappuntistiche in vigore tra la fine del sec. XVII e l’inizio del sec. XVIII. Nelle rispettive appendici ai capitoli si dànno le Tavole esplicative, con dati di natura codicologica, tecnico-musicale e testuale liturgica e gli elenchi dettagliati delle fonti responsoriali polifoniche rintracciate, manoscritte e a stampa. La seconda parte del lavoro presenta l’edizione critica della musica, con annessa la sua riproduzione in facsimile su CD. Nell’apparato critico la sezione dei Testi restituisce l’edizione filologica dei testi liturgici intonati.

Giustizia sanitaria e diseguaglianze globali in salute: il caso dell'aiuto allo sviluppo in sanità

Life expectancy at birth is the average number of years that a group of people born in the same year should live. The estimate for those born in 2010 is 80.2 years for Italy. On the other side of the chart are a number of countries in sub Saharan Africa. Haiti is in last place: children born in this country in 2010 have a life expectancy by an average of even 30 years, fifty in less than peers born in Italy. From a bioethical point of view, the first question that arises is: Is it right? Is it right that there is such inequality in health? The answer is simple: it is not right. But if we ask ourselves what are the best solution to remedy this situation, the answers become more than one. The differences in life expectancy depends on many factors, including no doubt the effectiveness of health systems. The scope of this work is precisely that of justice in health care and how the different general concepts related to it can be applied in health care settings with very limited financial and human resources. The first chapter describes the main inequalities in global health. The second discusses the main theories of justice. In the next chapter we reason on official development assistance and health cooperation. In the fourth we analyze the contribution of theories of justice through such issues as equity in health, the right of access to health services and right to health. In the fifth chapter the aim is to reason about global justice, the role of health in this context and how the official development assistance in health can contribute.

Campi elettromagnetici pulsanti nella terapia dell'artrosi del cane

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.

La trasformazione dei processi legislativi nella società dell'informazione: dall'e-Legislation all'e-Parliament

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.

Interfaccia web per un sistema di condivisione semantica dell'informazione: studio e implementazione

Questa tesi progettuale nasce per integrare gli sforzi attuali sullo sviluppo del web semantico. La piattaforma di riferimento sulla quale è stato svolto il presente lavoro è SMART-M3. Questa piattaforma mette a disposizione uno spazio condiviso di informazioni, rappresentate e accessibili secondo le tecnologie del web semantico. In questo scenario, nasce la necessità di disporre di un'interfaccia web capace di interagire con la piattaforma - in grado di risolvere la complessità intrinseca dei dati semantici - allo scopo di averne un completo controllo; ricerche precedenti a questo proposito hanno dato come frutto una libreria PHP che mi è stata consegnata come strumento per lo sviluppo dell'interfaccia. La tesi si è articolata in 3 fasi principali: una fase iniziale di documentazione sull'argomento, eseguita principalmente sul libro “A developer's guide to the semantic web” di Liyang Yu e sulla tesi “Ontologie per il web semantico: un'analisi comparativa.” di Indrit Beqiri; una seconda fase, quella principale, di sviluppo del progetto informatico; una terza fase, infine, di sviluppo di questo elaborato di tesi, da considerarsi come la trattazione di tutto il percorso soprascritto, dall'inizio alla fine, secondo l'ordine cronologico in cui si svolto l'intero processo della tesi.
