Sistema integrato di metodiche diagnostiche per il restauro della chiesa di Sant’Anna La Misericordia a Palermo
2010
E' mostrata l'applicazione di un sistema combinato di letture strumentali finalizzate all'ottenimento di una diagnosi attraverso un approccio dall'elevato rigore scientifico. Le analisi strumentali sono svolte nella chiesa di Sant'Anna a Palermo. The graphs show the application of a combined system of instrumental readings aimed to obtain a diagnosis through a high scientific and rigorous approach. The instrumental tests are executed in the St. Anne church in Palermo.

Theory of the elliptical Penning trap
2008
Abstract An ideal “Elliptical Penning Trap” is an ideal cylindrically symmetric Penning trap with an additional electrostatic quadrupolar potential ∝ κ ( x 2 − y 2 ) . This configuration is here investigated for arbitrary strength κ of the additional potential. Aside from the decoupled axial motion the system is characterized by a generalized cyclotron and a generalized magnetron frequency. While the former depends only weakly on κ , the magnetron frequency decreases rapidly with increasing κ , vanishing at a maximum value κ max which represents the stability limit for the magnetron motion. Magnetron orbits are elliptical, with their numerical excentricity tending toward unity as κ approa…
Gli strumenti del rinnovamento urbano di Trapani
2012
Trapani ha avviato un processo di profondo rinnovamento che in un breve arco di tempo ha visto la riqualificazione del porto, del centro storico e della città, riverberandosi anche sul suo territorio. Il processo ha preso avvio in occasione dello svolgimento nel porto di Trapani delle regate dell’America’s Cup nel 2005/06, per proseguire e radicarsi nel territorio grazie ad una programmazione integrata tra più soggetti della pubblica amministrazione, alla capacità di attrarre investimenti esogeni e al coinvolgimento dei privati e della popolazione locale. Trama portante delle politiche messe in atto è stata l’identità di Trapani come città portuale: gli interventi di trasformazione ne hanno…
The Hot Bands of Methane between 5 and 10 μm
1996
Experimental line intensities of 1727 transitions arising from nine hot bands in the pentad-dyad system of methane are fitted to first and second order using the effective dipole moment expansion in the polyad scheme. The observed bands are nu3 - nu2, nu3 - nu4, nu1 - nu2, nu1 - nu4, 2nu4 - nu4, nu2 + nu4 - nu2, nu2 + nu4 - nu4, 2nu2 - nu2, and 2nu2 - nu4, and the intensities are obtained from long-path spectra recorded with the Fourier transform spectrometer located at Kitt Peak National Observatory. For the second order model, some of the 27 intensity parameters are not linearly independent, and so two methods (extrapolation and effective parameters) are proposed to model the intensities …
Gone before its known? Camera-trapping shows alarming levels of putative hybrids in the wildcat (Felis silvestris) population of the Gargano National…
2022
Abstract The European wildcat is a small carnivore widespread across Europe and hybridization with the domestic cat is one of the major threats to wildcats. We estimate the population density of wild-living cats (both wildcats and putative hybrids based on pelage) in the Gargano National Park (Southern Italy). We sampled 20 stations for 540 camera days. We obtained 23 images from 17 detections at 10 cameras, and we identified 10 individuals (6 wildcats and 4 putative hybrids). Population density was estimated at 0.34 ± 0.15 SE wild-living cats/km2. The proportion of putative hybrids indicates an alarming hybridization for this population.
SPARC is a new myeloid-derived suppressor cell marker licensing suppressive activities
2019
Myeloid-derived suppressor cells (MDSC) are well-known key negative regulators of the immune response during tumor growth, however scattered is the knowledge of their capacity to influence and adapt to the different tumor microenvironments and of the markers that identify those capacities. Here we show that the secreted protein acidic and rich in cysteine (SPARC) identifies in both human and mouse MDSC with immune suppressive capacity and pro-tumoral activities including the induction of epithelial-to-mesenchymal transition (EMT) and angiogenesis. In mice the genetic deletion of SPARC reduced MDSC immune suppression and reverted EMT. Sparc−/− MDSC were less suppressive overall and the granu…
Tristetraprolin regulation of interleukin-22 production
2015
AbstractInterleukin (IL)-22 is a STAT3-activating cytokine displaying characteristic AU-rich elements (ARE) in the 3′-untranslated region (3′-UTR) of its mRNA. This architecture suggests gene regulation by modulation of mRNA stability. Since related cytokines undergo post-transcriptional regulation by ARE-binding tristetraprolin (TTP), the role of this destabilizing protein in IL-22 production was investigated. Herein, we demonstrate that TTP-deficient mice display augmented serum IL-22. Likewise, IL-22 mRNA was enhanced in TTP-deficient splenocytes and isolated primary T cells. A pivotal role for TTP is underscored by an extended IL-22 mRNA half-life detectable in TTP-deficient T cells. Lu…
Cooperation of Two mRNA-Binding Proteins Drives Metabolic Adaptation to Iron Deficiency
2008
Summary Iron (Fe) is an essential cofactor for a wide range of cellular processes. We have previously demonstrated in yeast that Cth2 is expressed during Fe deficiency and promotes degradation of a battery of mRNAs leading to reprogramming of Fe-dependent metabolism and Fe storage. We report here that the Cth2-homologous protein Cth1 is transiently expressed during Fe deprivation and participates in the response to Fe deficiency through the degradation of mRNAs primarily involved in mitochondrially localized activities including respiration and amino acid biosynthesis. In parallel, wild-type cells, but not cth1 Δ cth2 Δ cells, accumulate mRNAs encoding proteins that function in glucose impo…
Evaluation of mycotoxins and their metabolites in human breast milk using liquid chromatography coupled to high resolution mass spectrometry
2014
Humans can be exposed to mycotoxins through the food chain. Mycotoxins are mainly found as contaminants in food and could be subsequently excreted via biological fluids such as urine or human breast milk in native or metabolised form. Since breast milk is usually supposed as the only food for new-borns, the occurrence of mycotoxins in thirty-five human milk samples was evaluated by a newly developed method based on QuEChERS extraction and UHPLC-HRMS detection. The method described here allows the detection of target mycotoxins in order to determine the quality of this initial feeding. The method has been fully validated, with recoveries ranging from 64% to 93% and relative standard deviatio…
