Advanced Strategies for Food-Grade Protein Production: A New E. coli/Lactic Acid Bacteria Shuttle Vector for Improved Cloning and Food-Grade Expressi…
2019
Food-grade production of recombinant proteins in Gram-positive bacteria, especially in LAB (i.e., Lactococcus, Lactobacillus, and Streptococcus), is of great interest in the areas of recombinant enzyme production, industrial food fermentation, gene and metabolic engineering, as well as antigen delivery for oral vaccination. Food-grade expression relies on hosts generally considered as safe organisms and on clone selection not dependent on antibiotic markers, which limit the overall DNA manipulation workflow, as it can be carried out only in the expression host and not in E. coli. Moreover, many commercial expression vectors lack useful elements for protein purification. We constructed a &ld…
Paracamelichnum Jumillensisn.ichnogen. n.ichnosp., Upper Miocene Camelidae Ichnites from the Hoya de la Sima site (Murcia, Spain)
2009
In the proximity of Jumilla (Murcia, Spain) there is a site called Hoya de la Sima with mammal footprints dating from the Upper Miocene. This site is an old gypsum quarry where footprints of Hipparion, Pecoripeda, Carnivora, Ursidae, and Proboscidea were discovered. While the site was being cleaned and conditioned after the discovery to protect the prints, Camelidae and other prints were unearthed and are currently being studied. The description of the Camelidae ichnites demonstrates that these belong to a new ichnogenera, produced by the prints of Paracamelus. The grouping of trackways is congruent with the gregariousness of these animals and with the concentration observed in similar site…
Superconductivity in one dimension
2008
Superconducting properties of metallic nanowires can be entirely different from those of bulk superconductors because of the dominating role played by thermal and quantum fluctuations of the order parameter. For superconducting wires with diameters below $ \sim 50$ nm quantum phase slippage is an important process which can yield a non-vanishing wire resistance down to very low temperatures. Further decrease of the wire diameter, for typical material parameters down to $\sim 10$ nm, results in proliferation of quantum phase slips causing a sharp crossover from superconducting to normal behavior even at T=0. A number of interesting phenomena associated both with quantum phase slips and with …
1997
We have determined by forced Rayleigh scattering the diffusion coefficients of photo-labeled polystyrene micronetwork spheres (radii ≤ 10 nm) in melts of linear polyvinylmethylether (M W ≤ 40000 g/mol) at temperatures of 20-80°C. An expected slippage of the spheres through the meshes of the entanglement network appears possible but is still within the experimental uncertainty of our results.
Critical Structural Defects Explain Filamin A Mutations Causing Mitral Valve Dysplasia
2019
Mitral valve diseases affect approximately 3% of the population and are the most common reasons for valvular surgery because no drug-based treatments exist. Inheritable genetic mutations have now been established as the cause of mitral valve insufficiency, and four different missense mutations in the filamin A gene (FLNA) have been found in patients suffering from non-syndromic mitral valve dysplasia (MVD). The FLNA protein is expressed, in particular, in endocardial endothelia during fetal valve morphogenesis and is key in cardiac development. The FLNA-MVD causing mutations are clustered in the N-terminal region of FLNA. How the mutations in FLNA modify its structure and function, have mos…
Life Cycle Assessment della filiera di trattamento di biomasse residuali: un caso studio
2022
Il presente lavoro descrive i risultati dell’analisi di Life Cycle Assessement, sviluppata in accordo agli standard della serie ISO 14040, di un processo di trattamento di biomasse residuali di origine forestale da impiegare per la successiva valorizzazione energetica. L’analisi è riferita ad 1 kg di cippato, selezionato come unità funzionale. I confini del sistema hanno incluso le fasi di raccolta della biomassa residuale (strascico indiretto e diretto), cippatura della biomassa, raccolta e trasporto del cippato all’impianto di valorizzazione energetica. I risultati dello studio mostrano che la filiera in esame, con riferimento all’unità funzionale, causa un impatto di 0,027 kg CO2eq e det…
Angela Lattanzi e Filippa Maria Aliberti siciliane per adozione o nascita: due vite per l’arte
2022
Angela Lattanzi e Filippa Maria Aliberti sono due interessanti figure del ’900 che sommano l’attività di funzionarie statali – votate alla tutela del patrimonio – alla ricerca e allo studio sul campo, operando in due diversi contesti culturali e geografici, dalla Sicilia al Veneto passando per Roma. Approfittando della comune ‘cittadinanza’ siciliana per nascita o per adozione, attraverso l’apporto di fonti edite ed inedite, si ricostruiscono i tratti salientidel periodo trascorso sull’Isola, che per l’una coincide con l’attività matura e la seconda esperienza matrimoniale, mentre per l’altra con l’infanzia e la formazione scolastica e universitaria, determinando orientamenti, propensioni e…
I marginalia di Dino Buzzati: schemi, illustrazioni e disegni
2022
Secondo questa proposta di lettura dell'opera grafica di Dino Buzzati, che può essere estesa anche ad altri autori dal doppio talento, i disegni ai margini della scrittura possono essere interpretati allora nella loro funzione di relazione tra le arti che si risolve in una interazione, una negoziazione, uno slittamento oppure un conflitto, una cancellatura. Inoltre le annotazioni ai margini della scrittura, soprattutto nelle loro versioni grafiche, costituiscono una forma di introspezione autobiografica assai preziosa per ricostruire il profilo del loro autore, se scrittore e disegnatore al contempo.
Die autorisierende Funktion der Widmung in den Übersetzungen von Agrippas 'De nobilitate et praeccellentia foeminei sexus' (1529)
2020
Heinrich Cornelius Agrippa von Nettesheims Declamatio de nobi-litate et praecellentia foeminei sexus, der zu den wichtigsten Beiträgen zur sogenann-ten Querelle des femmes zählt, wurde 1529 Margarete von Österreich (1480–1530) ge-widmet. Die Übersetzungen des Traktats, die im 16. und 17. Jahrhundert erschienen, wurden aber oftmals mit neuen Widmungen ausgestattet. Schwerpunkt der vorliegen-den Arbeit ist die Analyse der sozio-pragmatischen und autorisierenden Funktion dieser Texte. In den Übersetzungen verliert die Widmung ihre ursprüngliche Rolle: Sie wird nicht mehr von den Absichten des Autors bestimmt, sondern modelliert sich durch den Produktions-, Übersetzungs- und Rezeptionsvorgang,…
Antikisierende Liebesgeschichten im Taschenbuchformat – Die Briefromane ›Menander und Glycerion‹ und ›Krates und Hipparchia‹
2021
The article analyzes the two later works of Christoph Marin Wieland, Menander and Glycerion, 1803, and Krates and Hipparchia, 1804. The actions of the short epistolary novels take place in ancient Greece. In this article are analyzed the formal, thematic and local similarities. In this article I would like to focus on the reason why shortly after the publication of the long letter novel Aristipp, 1801, Christoph Martin Wieland changes his concept of text types.
