Il teatro romano di Althiburos (M’deina, el Kef). Tunisia
2015
Il contributo delinea brevemente le attività della missione archeologica dell'università di Macerata ad Althiburos, svolta in collaborazione con l'Institut National du Patrimoine di tunisi e con il Politecnico di Bari. La missione ha per oggetto lo studio, lo scavo e la valorizzazione del teatro romano di Althiburos.
Extraordinary tuning of a nanocavity by a near-field probe
2011
Abstract We report here an experimental observation of an extraordinary near-field interaction between a local probe and a small-volume solid-state nanocavity. We directly compare the normally observed near-field interaction regime driven by the perturbation theory and then report the extraordinary interaction regime. Subsequently, we show that the cavity can take up to 2 min to recover from this interaction after removing the probe and that leads to an extraordinary blue-shift of the cavity resonance wavelength (∼15 nm) which depends on the probe motion above the cavity and not the position. The reasons for this effect are not fully understood yet but we try to give some explanations.
Formation of a new cell wall by protoplasts of Candida albicans: effect of papulacandin B, tunicamycin and Nikkomycin.
1987
SUMMARY: Incorporation of polysaccharides into the walls of regenerating protoplasts of Candida albicans was followed in the presence of papulacandin B, tunicamycin and nikkomycin. With the first drug, chitin was incorporated normally whereas incorporation of glucans and mannoproteins was significantly decreased. Tunicamycin decreased incorporation of all wall polymers when added at the beginning of the regeneration process but blocked only mannan and alkali-insoluble glucan incorporation when added after 5 h. Nikkomycin inhibited chitin synthesis, and the walls formed by the protoplasts were enriched in alkali-soluble glucan. Pulse-chase experiments suggested that a precursor-product relat…
Identification of a mannoprotein present in the inner layer of the cell wall of Saccharomyces cerevisiae.
1997
Cell wall extracts from the double-mutant mnn1 mnn9 strain were used as the immunogen to obtain a monoclonal antibody (MAb), SAC A6, that recognizes a specific mannoprotein--which we have named Icwp--in the walls of cells of Saccharomyces cerevisiae. Icwp runs as a polydisperse band of over 180 kDa in sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis of Zymolyase extracts of cell walls, although an analysis of the secretory pattern of the mannoprotein shows that at the level of secretory vesicles, it behaves like a discrete band of 140 kDa. Immunofluorescence analysis with the MAb showed that Icwp lies at the inner layer of the cell wall, being accessible to the antibody on…
Incorporation of specific wall proteins during yeast and mycelial protoplast regeneration in Candida albicans
1994
The kinectics of incorporation of two precursor mannoproteins into the regenerating cell wall of Candida albicans protoplasts have been followed at 28°C and 37°C using two monoclonal antibodies specific for protein epitopes (MAb 1B12 and 4C12) as probes. Both molecules were secreted from the beginning of the regeneration process, and their incorporation was retarded significantly. Analysis of the secreted materials by Western immunoblotting with MAb 1B12 allowed the identification of two closely migrating bands at apparent Mr higher than 170 kDa and significant amounts of a highly polydisperse material of even greater molecular mass. Some of these mannoproteinaceous species carried both N- …
Wall formation by Candida albicans yeast cells: synthesis, secretion and incorporation of two types of mannoproteins.
1993
SUMMARY: The mannoprotein components solubilized from the walls of Candida albicans blastoconidia following degradation of the glucan network with β-glucanase (Zymolyase) have higher molecular masses than their probable precursors present in the supernatant of regenerating protoplasts. It therefore appears that the mannoproteins are released from the walls as part of supramolecular complexes. Immunological analysis using both polyclonal and monoclonal antibodies has demonstrated the probable relationship between molecules found in a mixed membrane preparation, those secreted by regenerating protoplasts, and those present in yeast cell walls. Some mannoproteins secreted by protoplasts incuba…
Effects of PCSK9 variants on common carotid artery intima media thickness and relation to ApoE alleles.
2009
BACKGROUND: PCSK9 plays a key role in plasma cholesterol metabolism by modulating the expression of LDL receptors. OBJECTIVE AND METHODS: In this study we investigated the effects of two common polymorphism of the PCSK9 gene (E670G and I474V) on the intima media thickness of the common carotid artery and the possible relation with polymorphisms of apolipoprotein E in 1541 middle aged subjects selected from the general population enrolled in the PLIC study and confirmed the major findings in a second free-living population enrolled in the Ventimiglia study. RESULTS: 670G carriers showed significantly increased plasma total cholesterol, LDL-cholesterol, and Apo levels B while no significant d…
Architecture et communauté italienne en Tunisie pendant les vingt ans du fascisme
2011
Segmentato in cicli formalmente eterogenei, e però omologabili in base al comune denominatore della facies mediterranea, il filone delle architetture costruite negli anni Trenta dagli italiani a Tunisi, a Biserta, a Sousse, a Sfax e a Ferryville si mostra, dunque, principalmente tributario dei modi Déco della costa meridionale della Francia (con apprezzabili riferimenti all’edilizia coeva di Marsiglia e di Nizza). Succede pure che questo generale orientamento, limitatamente ad una ridotta aliquota di esempi di architetture ideate con maggiore respiro culturale, possa contemplare mediazioni con le espressioni più innovative di quella modernità accademizzante che nella Parigi di quegli anni a…
Architectures des Italiens à l'époque du Protectorat francais
2011
Il contributo degli italiani al “nuovo” volto della Tunisia nel periodo del protettorato francese ha la sua più tangibile manifestazione nel settore della produzione edilizia. È principalmente nella capitale Tunisi che, fino all’inizio degli anni Quaranta del XX secolo, si manifesta con maggiore incisività e riconoscibilità questo fenomeno nel contesto della considerevole trasformazione urbana operata, a partire dall’ultimo decennio dell’Ottocento, con l’attuazione del piano di ampliamento redatto dai tecnici del Genio Militare dell’Esercito Francese. Inizia così la mutazione d’età contemporanea della forma urbana di Tunisi. Diversamente da altri impianti urbani realizzati sempre dall’ammin…
IL PROGETTO URBANO NELLA CITTA' DI TUNISI E NEL MEDITERRANEO

Oggetto della comunicazione è una riflessione sul progetto urbano nella città di Tunisi e nel Mediterraneo. Sono state fatte delle riflessioni sui progetti urbani di Fernand Pouillon, Hassan Fathy, Jaques Marmey, Faruk Ben Miled, Vittorio Gregotti, Pasquale Culotta ed altri architetti, realizzati nelle città del Mediterraneo.
