Le Fonti Pubbliche Medioevali a Fermo Restauro e Valorizzazione della Fonte San Francesco di Paola

La tesi inizia con lo studio degli antichi sistemi di adduzione delle acque a Fermo (nel periodo compreso tra l'età romana e l'età medioevale), per poi trattare il tema delle fonti pubbliche medioevali presenti nella città e quelle monumentali esistenti nella regione Marche. Infine si arriva al tema specifico della trattazione, andando ad analizzare la Fonte San Francesco di Paola fino a pervenire al progetto di restauro e di valorizzazione.

Francesco Platone de' Benedetti, il principe dei tipografi bolognesi. Annali tipografici (1482-1496).

This work is focused on the reconstruction of the intellectual biography of Francesco Platone de' Benedetti, prince of the Bologna's printers (1482-1486), that is the same with his typographical outputs. The research had been divided in two parts: the first, with his life, invesitigated by archive documents, and the second part, focused on the census of his editions, with a particular attention to his types. The research on the typographical types had been developed with Adobe Photoshop, that had allowed me to virtually reconstruct the cases of the Gotic and Roman types used by de' Benedetti.

La riunificazione del frammento nell'ex convento di San Francesco. Un centro per la cultura restituito alla città di Mirandola.

Il lavoro svolto si concentra sulla città di Mirandola, dopo il terremoto del 2012. Viene svolto uno studio storico della città, e un'analisi sullo stato di fatto. Riflessioni sul limite tra città contemporanea e città storica. Viene proposta la ricostruzione del segno delle mura come limite, in modo da restituire un'identità alla città. Infine, il progetto si concentra sull'area dell'ex convento di San Francesco, complesso abbandonato dopo il sisma. La volontà è quella di riuscire a restituirlo alla cittadini di Mirandola, come nuovo centro culturale. Il progetto si impegna a mantenere l'esistente, aggiungendo un nuovo volume, che verrà occupata da una sala conferenze e da una parte della biblioteca.

Electrochemical imaging of living cell metabolism: investigation on Warburg effect in cancer

Cancer is one of the principal causes of death in the world; almost 8.2 million of deaths were counted in 2012. Emerging evidences indicate that most of the tumors have an increased glycolytic rate and a detriment of oxidative phosphorylation to support abnormal cell proliferation; this phenomenon is known as aerobic glycolysis or Warburg effect. This switching toward glycolysis implies that cancer tissues metabolize approximately tenfold more glucose to lactate in a given time and the amount of lactate released from cancer tissues is much greater than from normal ones. In view of these fundamental discoveries alterations of the cellular metabolism should be considered a crucial hallmark of cancer. Therefore, the investigation of the metabolic differences between normal and transformed cells is important in cancer research and it might find clinical applications. The aim of the project was to investigate the cellular metabolic alterations at single cell level, by monitoring glucose and lactate, in order to provide a better insight in cancer research. For this purpose, electrochemical techniques have been applied. Enzyme-based electrode biosensors for lactate and glucose were –ad hoc- optimized within the project and used as probes for Scanning Electrochemical Microscopy (SECM). The UME biosensor manufacturing and optimization represented a consistent part of the work and a full description of the sensor preparation protocols and of the characterization methods employed is reported. This set-up (SECM used with microbiosensor probes) enabled the non-invasive study of cellular metabolism at single cell level. The knowledge of cancer cell metabolism is required to design more efficient treatment strategies.

Genetic variation in IL28B is associated with chronic hepatitis C and treatment failure: a genome-wide association study

Hepatitis C virus (HCV) induces chronic infection in 50% to 80% of infected persons; approximately 50% of these do not respond to therapy. We performed a genome-wide association study to screen for host genetic determinants of HCV persistence and response to therapy.

Mitral regurgitation

Mitral regurgitation (MR) involves systolic retrograde flow from the left ventricle into the left atrium. While trivial MR is frequent in healthy subjects, moderate to severe MR constitutes the second most prevalent valve disease after aortic valve stenosis. Major causes of severe MR in Western countries include degenerative valve disease (myxomatous disease, flail leaflet, annular calcification) and ischaemic heart disease, while rheumatic disease remains a major cause of MR in developing countries. Chronic MR typically progresses insidiously over many years. Once established, however, severe MR portends a poor prognosis. The severity of MR can be assessed by various techniques, Doppler echocardiography being the most widely used. Mitral valve surgery is the only treatment of proven efficacy. It alleviates clinical symptoms and prevents ventricular dilatation and heart failure (or, at least, it attenuates further progression of these abnormalities). Valve repair significantly improves clinical outcomes compared with valve replacement, reducing mortality by approximately 70%. Reverse LV remodelling after valve repair occurs in half of patients with functional MR. Percutaneous, catheter-based to mitral valve repair is a novel approach currently under clinical scrutiny, with encouraging preliminary results. This modality may provide a valuable alternative to mitral valve surgery, especially in critically ill patients.

Evaluation of administration of isoflurane at approximately the minimum alveolar concentration on depression of a nociceptive withdrawal reflex evoked by transcutaneous electrical stimulation in ponies

OBJECTIVE: To investigate effects of isoflurane at approximately the minimum alveolar concentration (MAC) on the nociceptive withdrawal reflex (NWR) of the forelimb of ponies as a method for quantifying anesthetic potency. ANIMALS: 7 healthy adult Shetland ponies. PROCEDURE: Individual MAC (iMAC) for isoflurane was determined for each pony. Then, effects of isoflurane administered at 0.85, 0.95, and 1.05 iMAC on the NWR were assessed. At each concentration, the NWR threshold was defined electromyographically for the common digital extensor and deltoid muscles by stimulating the digital nerve; additional electrical stimulations (3, 5, 10, 20, 30, and 40 mA) were delivered, and the evoked activity was recorded and analyzed. After the end of anesthesia, the NWR threshold was assessed in standing ponies. RESULTS: Mean +/- SD MAC of isoflurane was 1.0 +/- 0.2%. The NWR thresholds for both muscles increased significantly in a concentration-dependent manner during anesthesia, whereas they decreased in awake ponies. Significantly higher thresholds were found for the deltoid muscle, compared with thresholds for the common digital extensor muscle, in anesthetized ponies. At each iMAC tested, amplitudes of the reflex responses from both muscles increased as stimulus intensities increased from 3 to 40 mA. A concentration-dependent depression of evoked reflexes with reduction in slopes of the stimulus-response functions was detected. CONCLUSIONS AND CLINICAL RELEVANCE: Anesthetic-induced changes in sensory-motor processing in ponies anesthetized with isoflurane at concentrations of approximately 1.0 MAC can be detected by assessment of NWR. This method will permit comparison of effects of inhaled anesthetics or anesthetic combinations on spinal processing in equids.

Therapie des femoroazetabulären Impingements über die chirurgische Hüftluxation [Surgical dislocation of the hip for the treatment of femoroacetabular impingement. Technique and results]

Surgical dislocation of the hip is a safe and established technique for treating femoroacetabular impingement. The complication rate is low, and if the correct technique that respects the blood supply is used, femoral head necrosis does not occur. The most frequent complications are minor ectopic bone formation and nonunion of the greater trochanter. Surgical treatment includes the correction of femoral and acetabular pathology. Clinically, in approximately 75-80% of cases a good-to-excellent result can be obtained. However, patients with advanced degenerative changes (exceeding stage 1 osteoarthritis using the Tönnis score) have worse outcomes. It has also been shown that preservation of the labrum has a significant influence on both clinical outcome and progression of osteoarthritis: It seems that preservation of the labrum is mandatory.

Scleroderma Renal Crisis: A Rare but Severe Complication of Systemic Sclerosis

Scleroderma renal crisis (SRC) is a major complication in patients with systemic sclerosis (SSc). It is characterized by malignant hypertension and oligo/anuric acute renal failure. SRC occurs in 5% of patients with SSc, particularly in the first years of disease evolution and in the diffuse form. The occurrence of SRC is more common in patients treated with glucocorticoids, the risk increasing with increasing dose. Left ventricular insufficiency and hypertensive encephalopathy are typical clinical features. Thrombotic microangiopathy is detected in 43% of the cases. Anti-RNA-polymerase III antibodies are present in one third of patients who develop SRC. Renal biopsy is not necessary if SRC presents with classical features. However, it can help to define prognosis and guide treatment in atypical forms. The prognosis of SRC has dramatically improved with the introduction of angiotensin-converting enzyme inhibitors (ACEi). However, 5 years survival in SSc patients who develop the full picture of SRC remains low (65%). SRC is often triggered by nephrotoxic drugs and/or intravascular volume depletion. The treatment of SRC relies on aggressive control of blood pressure with ACEi, if needed in combination with other types of antihypertensive drugs. Dialysis is frequently indicated, but can be stopped in approximately half of patients, mainly in those for whom a perfect control of blood pressure is obtained. Patients who need dialysis for more than 2 years qualify for renal transplantation.

Scrivere di architettura intorno al 1780: Andrea Memmo e Francesco Milizia tra il Veneto e Roma

Andrea Memmo ist in der Geschichte der Architekturtheorie vor allem deswegen bekannt, weil er durch die Veröffentlichung der 'Elementi d'architettura lodoliana, ossia l'arte del fabricare con solidità scientifica e con eleganza non capricciosa' (Rom 1786) entscheidend dazu beigetragen hat, die originellen architektonischen Konzepte der Nachwelt zu überliefern, die der venezianische Franziskaner Carlo Lodoli zwischen 1730 und 1750 mündlich verbreitet hatte. Der vorliegende Beitrag unternimmt es, anhand des bislang für verloren gehaltenen 'Piano Accademico', den Memmo um 1767 für die venezianische Akademie zum Zwecke der Unterrichtsreform der bildenden Künste (Skulptur, Malerei und Architektur) ausgearbeitet hatte, klarzustellen, welche wichtige Rolle der Aufenthalt in Rom für Memmo gespielt hat. Dies wird auch durch die Briefe belegt, die er während der Ausarbeitung seines Werkes über Lodoli verfasst hatte. Im Rom der 1780er Jahre waren für ihn ausschlaggebend 1. die Beziehungen zur dortigen Accademia di S. Luca und 2. seine Freundschaft zum spanische Botschafter José Nicolas de Azara. Azara hatte ihn dazu ermutigt, über den Padre Lodoli zu schreiben, um dessen Gedanken denen des mit Azara befreundeten Francesco Milizia gegenüberzustellen.
