Il catalogo aperto dei manoscritti Malatestiani

I manoscritti medievali conservati nella storica biblioteca cesenate sono 429, in parte notevole (343) collocati nella Biblioteca Malatestiana, fondata da Malatesta Novello, signore della città, alla metà del secolo XV. Ad essi si aggiungono codici della biblioteca privata di papa Pio VII (il cesenate Gregorio Barnaba Chiaramonti), otto corali commissionati dal cardinale Bessarione, sette corali di proprietà della Diocesi di Cesena e i manoscritti della Biblioteca Comunale o Comunitativa, costituitasi all`inizio dell`Ottocento con i fondi delle corporazioni religiose soppresse. In occasione del convegno di studi promosso nel 2003 per il 550° della fondazione, la Malatestiana ha presentato il Catalogo aperto dei manoscritti Malatestiani, nato dalla collaborazione con Antonio Cartelli e Marco Palma dell`Università di Cassino ma realizzato all`interno della Biblioteca. Esso è in sostanza un sistema informativo che fonda la sua struttura e le sue funzioni sull`utilizzo intensivo delle tecnologie dell`informazione e della comunicazione. Per la costruzione del catalogo aperto si è scelto di utilizzare l`applicativo WinISIS. Il sito del catalogo aperto è ospitato gratuitamente sul server pubblico della provincia di Forlì-Cesena. Il catalogo aperto contempla tre accessi in base alla lingua degli utenti: italiano, inglese e tedesco, ed è articolato in tre sezioni: la prima, contenente monografie e articoli, utili alla conoscenza della biblioteca e dei suoi fondi; la seconda presenta le descrizioni dei codici, la bibliografia relativa a ciascun manoscritto posseduto dalla biblioteca e le immagini che riproducono tutto o in parte le pagine dei manoscritti; l`ultima si basa su un sottosistema informativo ad accesso protetto e differenziato, molto simile ad un forum, in cui le persone interessate allo studio dei manoscritti della biblioteca possono pubblicare lavori oppure scambiarsi informazioni, formulare progetti e dibattere problemi di comune interesse

Imaging of hibernomas: A retrospective study on twelve cases

<p>Abstract</p> <p>Background</p> <p>To analyze the imaging features of hibernomas on computed tomography (CT) and magnetic resonance (MRI).</p> <p>Methods</p> <p>Twelve hibernomas were retrospectively assessed with CT and MR imaging and compared to the histology of the specimen</p> <p>Results</p> <p>Nine females and three males with a mean age of 30 years were included. Ten tumors occurred in the thigh and two affected the subcutis of the periscapular and buttock regions. On eight CT scans, seven (87,5%) lesions were homogeneous and mildly to moderately hyperdense compared to subcutaneous fat while one lesion was heterogeneous with mixed hypo and hyperattenuating areas. On six T1W images, five (83,3%) lesions appeared homogeneous and hypointense relative to subcutaneous fat and one was heterogeneous. Incomplete fat suppression was depicted in all cases. All lesions displayed marked enhancement. Large intratumoral vessels were depicted in three of the 12 (25%) cases. Septations were depicted on four of the eight unenhanced CT and on all six MRI examinations.</p> <p>Conclusions</p> <p>Hibernoma usually appears hypodense and hypointense relative to subcutaneous fat on pre-contrast CT and MR T1W with variable enhancement patterns and incomplete fat suppression on STIR or fat-saturated sequences. These characteristics relate directly to the presence of brown fat. However, atypical findings such as heterogeneous patterns of mixed fatty and non fatty components on unenhanced CT and MR T1W can be also encountered. Absence of large intratumoral vessels should not exclude hibernomas from the differential diagnosis of regional lipomatous tumors.</p

Biochar from gasification in cultivated soils and riparian buffer zones: Chemical characterization

During rain events, pollutants in agricultural soils can be transported from fields to surface and/or groundwater resulting in contamination of streams and rivers. Researchers and farmers must work together to find solutions to ensure the preservation of crop production without jeopardizing water quality or the health of the ecosystem. Establishment of riparian zones may reduce the effects of diffuse discharges of pollutants into waterways. The addition of biochar to soils, particularly in a riparian zones, can reduce the mobility of contaminants and improve removal efficiency due its sorptive capacity.

Cutaneous angiomatosis-like presentation in koi carp (Cyprinus carpio koi): Clinical–pathological investigations

The skin represents an indicator of an animal's health status. Causes of cutaneous diseases in fish most often trace back to biological agents. However, fish skin diseases can also arise from a complex interaction of infectious and non-infectious causes, making it more difficult to identify a specific aetiology. In the period between April and September of the years 2019–2022, four koi carp (Cyprinus carpio koi) from two European countries presented with multifocal, irregularly round, few mm to 1 cm, variably raised cutaneous reddened areas. The fish displayed good general condition. Cutaneous samples, investigated by microbiological and molecular methods and microscopy, did not indicate a primary pathogenic agent. Gross and histological findings of the cutaneous biopsies were consistent with a multifocal/reactive process centred on dermal vessels. The histological features were reminiscent of angiomatosis, a benign proliferative condition affecting the dermal vessels of mammals, including human patients. The clinical–pathological presentation and the dermatologic condition that affected the koi carp are discussed and compared with the veterinary and human literature

Vascular bone tumors: A proposal of a classification based on clinicopathological, radiographic and genetic features

The classification of vascular bone tumors remains challenging, with considerable morphological overlap spanning across benign to malignant categories. The vast majority of both benign and malignant vascular tumors are readily diagnosed based on their characteristic histological features, such as the formation of vascular spaces and the expression of endothelial markers. However, some vascular tumors have atypical histological features, such as a solid growth pattern, epithelioid change, or spindle cell morphology, which complicates their diagnosis. Pathologically, these tumors are remarkably similar, which makes differentiating them from each other very difficult. For this rare subset of vascular bone tumors, there remains considerable controversy with regard to the terminology and the classification that should be used. Moreover, one of the most confusing issues related to vascular bone tumors is the myriad of names that are used to describe them. Because the clinical behavior and, consequently, treatment and prognosis of vascular bone tumors can vary significantly, it is important to effectively and accurately distinguish them from each other. Upon review of the nomenclature and the characteristic clinicopathological, radiographic and genetic features of vascular bone tumors, we propose a classification scheme that includes hemangioma, hemangioendothelioma, angiosarcoma, and their epithelioid variants. © ISS 2012
