Formation and distortion of iodidoantimonates(III): the first isolated [SbI6]3- octahedron
2017
The ability to intentionally construct, through different types of interactions, inorganic–organic hybrid materials with desired properties is the main goal of inorganic crystal engineering. The primary deformation, related to intrinsic interactions within inorganic substructure, and the secondary deformation, mainly caused by the hydrogen bond interactions, are both responsible for polyhedral distortions of halogenidoantimonates(III) with organic cations. The evolution of structural parameters, in particular the Sb—I secondary- and O/N/C—H...I hydrogen bonds, as a function of temperature assists in understanding the contribution of those two distortion factors to the irregularity of [SbI6]…

Enterococcus asini sp. nov. isolated from the caecum of donkeys (Equus asinus)
1998
Several Gram-positive, non-spore-forming and non-motile bacteria consisting of pairs or chains of cocci were isolated during an investigation of the bacterial flora of the caecum of donkeys. Physiological and metabolic data indicated that the strains belong to the genus Enterococcus; phenotypic traits of these organisms were not consistent with any of the currently known Enterococcus species. 16S rRNA gene sequence analysis placed these strains in the genus Enterococcus. Their closest relatives are Enterococcus avium, Enterococcus faecium and Enterococcus pseudoavium with a sequence similarity of 97.4%. This group of strains can be differentiated from the other Enterococcus spp. by their ph…

Behavioural profile of drug users attending public drug-treatment centres in Sicily: the role of social context
2007
<p><strong>Objective</strong>: Investigations of injecting drug users (IDUs) have suggested that the social context may influence high-risk behaviours in this population. The aim of this study was to describe knowledge, attitudes and behaviours of IDUs attending public drug-treatment centres in our area.</p><p><strong>Study design and methods</strong>: A cross-sectional survey was conducted between July 2002 and February 2004, enrolling 607 drug users attending four public drug-treatment centres in the Palermo area. Two of them were located inside the urban area, whereas the other two were in rural districts near the city. All participants answered …
Use of poly(amidoamine) drug conjugates for the delivery of antimalarials to Plasmodium
2013
Current malaria therapeutics demands strategies able to selectively deliver drugs to Plasmodium-infected red blood cells (pRBCs) in order to limit the appearance of parasite resistance. Here, the poly(amidoamines) AGMA1 and ISA23 have been explored for the delivery of antimalarial drugs to pRBCs. AGMA1 has antimalarial activity per se as shown by its inhibition of the in vitro growth of Plasmodium falciparum, with an IC50 of 13.7 μM. Fluorescence-assisted cell sorting data and confocal fluorescence microscopy and transmission electron microscopy images indicate that both polymers exhibit preferential binding to and internalization into pRBCs versus RBCs, and subcellular targeting to the par…
L'intervento nei centri storici: l'ANCSA e il caso Erice
2014
Il Convegno “Salvaguardia e risanamento dei centri storico-artistici”, svoltosi a Gubbio nel Settembre del 1960, offre l’occasione per fare un bilancio sulla situazione dei centri storici, sull’insufficienza normativa dei piani regolatori, sulla tecnica urbanistica e confrontare contemporaneamente le esperienze concrete di alcuni piani e il relativo approccio al tema dell’intervento nei centri storici. Il comitato promotore del Convegno di Gubbio, noto per avere prodotto la celebre Dichiarazione finale poi denominata “Carta di Gubbio”, si trasformerà l’anno successivo in Comitato permanente fondando a Gubbio l’Associazione nazionale centri storico-artistici (ANCSA). Appare significativo che…
Il VII Congresso nazionale di Storia dell'architettura
2014
Il saggio esplora il ruolo di Edoardo Caracciolo e il suo contributo nell'ambito del VII Congresso nazionale di Storia dell'architettura che si svolse a Palermo nel settembre del 1950, proponendo alcune riflessioni intorno alla figura di Caracciolo sullo sfondo di questo particolare contesto e sul sistema di relazioni intrecciate che il convegno restituisce. Il contributo indaga infatti sui molteplici canali, gli intrecci e le relazioni che legano Caracciolo ai principali protagonisti dei diversi contesti nazionali. In tal senso VII Congresso nazionale di Storia dell'architettura rappresenta un momento importante in un quadro di relazioni che Caracciolo costruisce nel tempo attraverso le ta…
