Chemical Composition and Evaluation of Insecticidal Activity of Seseli bocconei Essential Oils against Stored Products Pests
2022
In this study, the chemical composition of the essential oils (EOs) obtained from different aerial parts (flowers, leaves, and stems) of Seseli bocconei Guss., a wild species endemic of Sicily, was investigated. Furthermore, the EOs’ biocidal effects towards two pests of stored products, Sitophilus oryzae and Callosobruchus maculates, were evaluated. This activity was evaluated in Petri dish bioassays to establish the survival rate of adults treated with the EOs comparing them with solvent and a commonly used insecticide (pyrethrum). The data obtained from the toxicity bioassay evidenced that stems’ EOs and leaves’ EOs have a contact/fumigation effect towards the two insec…
Heavy flavour decay muon production at forward rapidity in proton--proton collisions at sqrt(s) = 7 TeV
2012
The production of muons from heavy flavour decays is measured at forward rapidity in proton-proton collisions at $\sqrt{s} = 7$ TeV collected with the ALICE experiment at the LHC. The analysis is carried out on a data sample corresponding to an integrated luminosity $L_{\rm int} = 16.5$ nb$^{-1}$. The transverse momentum and rapidity differential production cross sections of muons from heavy flavour decays are measured in the rapidity range 2.5 < y < 4, over the transverse momentum range 2 < $p_{\rm T}$ < 12 GeV/$c$. The results are compared to predictions based on perturbative QCD calculations.
AMPULLECTOMIA E CARCINOMA GIGANTE DELLA PAPILLA DI VATER
2007
The case of a giant carcinoma of Vater's papilla is reported. The clinical/diagnostic paths and therapeutic indications for ampullectomy are analysed on the basis of the good survival rate observed more than five years after transduodenal excision and in the light of the most recent literature. The authors believe that accurate, early diagnosis and histological typing is fundamental for an appropriate selection of patients when complex surgical decisions have to be taken. They consider ampullectomy to be a valid therapeutic option, certainly in the case of benign neoplasias, and duodenocephalopancreasectomy (DCP) to be the operation of choice for the treatment of ampullar and periampullar m…
Monte Carlo simulations of the solid-liquid transition in hard spheres and colloid-polymer mixtures
2010
Monte Carlo simulations at constant pressure are performed to study coexistence and interfacial properties of the liquid-solid transition in hard spheres and in colloid-polymer mixtures. The latter system is described as a one-component Asakura-Oosawa (AO) model where the polymer's degrees of freedom are incorporated via an attractive part in the effective potential for the colloid-colloid interactions. For the considered AO model, the polymer reservoir packing fraction is eta_p^r=0.1 and the colloid-polymer size ratio is q=sigma_p/\sigma=0.15 (with sigma_p and sigma the diameter of polymers and colloids, respectively). Inhomogeneous solid-liquid systems are prepared by placing the solid fc…
Le valenze della Danza Movimento Terapia in presenza e a distanza. Corpo e relazioni durante la pandemia del COVID-19
2022
Elena Mignosi e Fernando Battista approfondiscono nella loro articolo le specificità della Danza Movimento Terapia (DMT) e i suoi numerosi ambiti applicativi (educativo, formativo clinico, terapeutico, sociale/inclusivo , riabilitativo). Conducono quindi una riflessione sulle modalità in presenza e da remoto, individuando quale efficacia possa avere partecipare ad un esperienza artisctico-creativa e corporea attraverso uno schermo. La pandemia da Covid 19 ha infatti reso necessario ripensare quelli che erano ritenuti i punti cardine del setting di DMT e di individuare nuove forme di interazione. Infine essi presentano brevemente i capitoli della rivista che costituiscono gli Atti del Conveg…
A mathematical approach to model diffusion properties of sedimentary rocks relevant to Sicily cultural heritage
2007
Cultural heritage vestiges represent complex physical systems, able to interact with the environment through continuous exchanges of heat and fluids (water, air). In this wide context, particular relevance is assumed by transport phenomena and diffusion of pollutant, vehiculated inside the considered structure by water itself. Interaction mechanisms can be considered at various observation scales, depending on the material provenance and on its geometry and location. Involved materials are commonly constituted by porous rocks - more or less altered - belonging to geological sedimentary formations, as limestone, calcarenite and travertine. Their appreciable porosity affects significantly liq…

Alkamides from Echinacea angustifolia Interact with P-Glycoprotein of Primary Brain Capillary Endothelial Cells Isolated from Porcine Brain Blood Ves…
2013
The blood-brain barrier prevents the passage of toxic compounds from blood circulation into brain tissue. Unfortunately, drugs for the treatment of neurodegenerative diseases, brain tumors, and other diseases also do not cross the blood-brain barrier. In the present investigation, we used isolated porcine brain capillary endothelial cells and a flow cytometric calcein-AM assay to analyze inhibition of P-glycoprotein, a major constituent of the blood-brain barrier. We tested 8 alkamides isolated from Echinacea angustifolia and found that four of them inhibited P-glycoprotein-mediated calcein transport in porcine brain capillary endothelial cells.
