L'eroicomico
2014
Il saggio analizza la genesi e la metamorfosi del poema eroicomico nella modernità, tra Seicento e primo Ottocento, con attenzione anche al suo influsso sul romanzo e su altri generi letterari. The essay examines the mock-heroic poem's genesis and metamorphosis between the seventeenth and the nineteenth century, also dealing with its influence upon modern novel and other literary genres.
Evaluation of consistency in spheroid invasion assays
2016
Multicellular tumor spheroids embedded in a matrix represent invaluable tools to analyze cell invasion. Spheroid sizes and invasiveness are the main observables easily measurable to evaluate effects of biological or pharmaceutical manipulations on invasion. They largely account for these 3-D platforms variability, leading to flaws in data interpretation. No method has been established yet that characterizes this variability and guarantees a reliable use of 3-D platforms. Spheroid initial/end sizes and invasiveness were systematically analyzed and compared in spheroids of U87MG cells generated by three different methods and embedded at different times in a collagen matrix. A normality test w…
Investigation on the pollen morphology of traditional cultivars of Prunus species in Sicily
2012
In this study pollen grains of 13 cultivars and 3 rootstocks belonging to 5 species (<em>P. armeniaca</em>, <em>P. domestica</em>, <em>P. dulcis</em>, <em>P. persica</em>, <em>P. avium</em>) of the genus <em>Prunus </em>collected from North-East Sicily were examined for the micromorphological characterization through the scanning electron microscopy (SEM). The length of polar axis (<em>P</em>) and the equatorial diameter (<em>E</em>) of grain, <em>P/E </em>ratio, the length of colpi (<em>C</em>), diameter of perforations (<em>DP</em>) and the number of perforat…

New cut-off criterion for uninformative variable elimination in multivariate calibration of near-infrared spectra for the determination of heroin in …
2008
A new cut-off criterion has been proposed for the selection of uninformative variables prior to chemometric partial least squares (PLS) modelling. After variable elimination, PLS regressions were made and assessed comparing the results with those obtained by PLS models based on the full spectral range. To assess the prediction capabilities, uninformative variable elimination (UVE)-PLS and PLS were applied to diffuse reflectance near-infrared spectra of heroin samples. The application of the proposed new cut-off criterion, based on the t-Students distribution, provided similar predictive capabilities of the PLS models than those obtained using the original criteria based on quantile value. H…
Heroic Education: An Educational Project that Helps NEET People Orient Themselves to the Future, Work, and Training with the Skills They Need to Be S…
2022
Heroic education is an educational model that helps young people orient them selves towards the future, work, and training. It provides them with the skills they need to be successful in life. The program offers a variety of courses and activities that help participants learn about themselves and their world. It’s a great way for young people to get started on their path to success. The program is designed to help participants learn about their strengths and weaknesses. It also helps them learn about their options for the future. Heroic education is based on the principle that every young person has the potential to be a hero in their community. The program is offered in partnership with lo…
Intracellular glutathione in human hepatocytes incubated with S-adenosyl-L-methionine and GSH-depleting drugs
1991
Abstract The present study was undertaken to investigate (a) whether S- adenosyl- L -methionine (SAMe) added to culture medium can increase intracellular glutathione (GSH) levels in human hepatocytes and (b) whether SAMe can prevent the GSH depletion found in human hepatocytes incubated with GSH-depleting drugs (paracetamol, opiates, ethanol). Incubation of hepatocytes with increasing concentrations of SAMe resulted in a dose-dependent elevation of intracellular GSH content, which reached its maximum (35% increase) at 30 μM after 20 h. SAMe, as the only sulfur source in the medium, was efficient in repleting GSH-depleted hepatocytes following treatment with diethyl maleate. Incubation of hu…
Slow release oral morphine versus methadone for the treatment of opioid use disorder
2019
ObjectiveTo assess the efficacy of slow release oral morphine (SROM) as a treatment for opioid use disorder (OUD).DesignSystematic review and meta-analysis of randomised controlled trials (RCTs).Data sourcesThree electronic databases were searched through 1 May 2018: the Cochrane Central Register of Controlled Trials, MEDLINE and EMBASE. We also searched the following electronic registers for ongoing trials: ClinicalTrials.gov, WHO International Clinical Trials Registry Platform, Current Controlled Trials and the EU Clinical Trials Register.Eligibility criteria for selecting studiesWe included RCTs of all durations, assessing the effect of SROM on measures of treatment retention, heroin use…
Potential and energy of oblate spheroidal charge distributions
1989
Abstract The Poisson equation for a large class of charge distributions contained within oblate spheroids in solved and their energies are obtained. In many cases, the potential and the energy can be found by comparison with the solutions of the Poisson equation for prolate spheroidal charge distributions obtained in preceding works. The limits of validity of this comparison procedure are established. For the simplest cases the electrostatic energy is computed and, after suitable normalization, displayed graphically.
Search for dark matter from the Galactic halo with the IceCube neutrino telescope
2011
Self-annihilating or decaying dark matter in the Galactic halo might produce high energy neutrinos detectable with neutrino telescopes. We have conducted a search for such a signal using 276 days of data from the IceCube 22-string configuration detector acquired during 2007 and 2008. The effect of halo model choice in the extracted limit is reduced by performing a search that considers the outer halo region and not the Galactic Center. We constrain any large-scale neutrino anisotropy and are able to set a limit on the dark matter self-annihilation cross section of ⟨σAv⟩≃10-22 cm3 s-1 for weakly interacting massive particle masses above 1 TeV, assuming a monochromatic neutrino line spectrum.
