Gobius aterBellotti (Pisces, Perciformes): specie valida ed inclusa nella fauna italiana
No full textGobius aterBellotti (1888), hitherto known from Nice and Balearic Island, is also inc1uded in the Italian ichthyofauna. It was found onPosidoniabeads near Alghero (Sardinia). The study of its morphological characters confirms that this is a good species well different fromG. nigerL

Efficient DNA base excision repair in ataxia telangiectasia cells
No full textAtaxia telangiectasia (A-T) cells are sensitive to a broad range of free-radical-producing and alkylating agents. Damage caused by such agents is in part repaired by base excision [base excision repair (BER)]. Two BER pathways have been demonstrated in mammalian cells: a single-nucleotide-insertion pathway and a long-patch pathway involving resynthesis of 2-10 nucleotides. Although early studies failed to detect DNA-repair defects in A-T cells exposed to ionizing radiation and radiomimetic agents, more recent experiments performed in non-dividing A-T cells and the demonstrated interaction of the A-T-mutated protein (ATM) with the BRCA1 gene product suggest that a DNA-repair defect may underlie, at least in part, the radiation sensitivity in A-T cells. We have analysed BER of a single abasic site or a single uracil in two A-T families, using an in vitro BER system. In both families, the mutation involved was homozygous and completely inactivated the ATM protein. No difference was observed between affected individuals and heterozygous or homozygous wild-type relatives in their capacity to perform DNA repair by either one-nucleotide insertion or the long-patch pathway. Hence, the putative DNA-repair defect in A-T cells, if any, does not involve BER
OCCLUSIONE E POSTURA
No full textLa Società italiana di Odontostomatologia dello Sport da anni si occupa di dare una corretta definizione alla figura dell’Odontoiatra dello sport, un riferimento e una costante presenza per quanti praticano attività sportiva, a livello sia agonistico sia amatoriale.
In questo volume, nato dall'apporto dei numerosi ricercatori italiani della branca odontostomatologica da anni direttamente coinvolti nella prevenzione e nella cura di atleti delle diverse discipline sportive, vengono analizzati gli apporti di mascellari, denti, articolazione temporomandibolare, muscoli e scheletro dorso-cervicale nell’esecuzione degli atti motorî propri di ogni sport.
Il volume è suddiviso in macroaree:
- traumatologia dento-maxillofacciale: dal trauma alla terapia riabilitativa, con protocolli specifici e pratici
- prevenzione dei traumi, dalla metodologia alla progettazione e costruzione di bite e mouthguard individuali e personalizzati
- occlusione e postura e quanto è collegato alle patologie del tratto cervico-temporo-articolare
- alimentazione ed ecosistema orale
- odontoiatria e attività sportiva in età pediatrica, dal trattamento delle patologie ostruttive respiratorie alla scoliosi vertebrale
- laser e lesioni delle mucose orali negli atleti
- organizzazione dei sistemi sanitari odontoiatrici durante le competizioni sportive e modelli di prevenzione
- aspetti medico-legali e assicurativi riconducibili in traumatologia dentofacciale
- farmacologia odontoiatrica e doping
Bacteremia from streptococcus constellatus revealing a gastrointestinal stromal tumor
No full textBackground: Pyogenic Liver Abscesses (PLA) are the most common type of visceral abscess. They generally develop in a context of biliary disease or hematogenous seeding, but a complete diagnostic work-up is always required in order not to miss other important causes, including above all malignancies of the gastro-intestinal tract. Case presentation: Herein, we report a particular case of a 80 years-old immunocompetent woman hospitalized for sepsis. At the end of the diagnostic process, Streptococcus constellatus (Sc) was identified as the cause of sepsis, multiple PLA were found together with a previous unknown ileal malignancy. We speculated about a possible correlation among these three entities (i.e. sepsis from Sc, PLA and tumors). Conclusions: Detection of Sc in blood should raise red flags in clinicians as aggressive clinical presentation are possible
Enrico Cattaneo : Fotografare un'idea
No full textOltre ad aver raccontato l’arte e gli artisti del secondo Novecento attraverso la documentazione di cinquant’anni di mostre, studi e grandi manifestazioni pubbliche in Italia, Enrico Cattaneo (Milano, 1933-2019) ha sviluppato una personalissima ricerca visuale sui modi, i soggetti e i materiali della fotografia.
Questi due aspetti della sua attività, inseparabili fra loro come le due facce di una medaglia, si ricompongono nella fisionomia unitaria di un autore capace di mettere in questione i presupposti tecnici e concettuali del linguaggio fotografico.
Come lui stesso ha scritto: “L’opera d’arte contemporanea è spesso una cosa più un’idea... Difficile fotografare un’idea”.In addition to having chronicled art and artists of the second half of the 20th century by documenting fifty years of exhibitions, art research, and major public events in Italy, Enrico Cattaneo (Milan, 1933–2019) developed a highly personal visual investigation on the modes, languages, and materials of photography.
These two facets of his activity, indissolubly linked like the two sides of a coin, are recomposed in the overall profile of an author capable of questioning the technical and conceptual foundations of photography.
As he himself has written: ‘The contemporary work of art is often made up of a tangible thing and an idea ... It is difficult to capture an idea on film.
Enriching Data Lakes with Knowledge Graphs
No full textData lakes are repositories of data stored in natural/raw format. A data lake may include structured data from relational databases, semi-structured data (i.e., JSON, CSV), unstructured data (i.e., text data), or binary data (i.e., images, audio, video). It is usually built on top of cost-efficient infrastructures such as Hadoop, Amazon S3, MongoDB, ElasticSearch, etc. Several organisations rely on big data lakes for crucial tasks such as reporting, visualisation, advanced analytics, machine learning, and business intelligence. A major limitation of this solution is that without descriptive metadata and a mechanism to maintain it, such data tend to be noisy, making their management and analysis complex and time-consuming. Therefore, there is the need to add a semantic layer based on a formal ontology to describe the data and efficient mechanism to represent them as a knowledge graph. In this paper, we present a methodology to add a semantic layer to a data lake and thus obtain a knowledge graph that can support structured queries and advanced data exploration. We describe a practical implementation of a methodology applied to a data lake consisting of text data describing the online marketplace for lodging and tourism activities. We report statistics about the data lake and the resulting knowledge graph
