I Paralleli. Narratori contemporanei e classici italiani a confronto
2009
Cosa unisce Ludovico Ariosto a Wu Ming 5, Giorgio Faletti ad Alessandro Manzoni, Giacomo Leopardi a Sebastiano Vassalli? Nelle agili pagine di Matteo Di Gesù libri e autori vengono messi a confronto, in un succedersi di ‘paralleli’, ovvero recensioni doppie, la cui costante è l’accostamento di opere provenienti da tempi e contesti diversi, nell’ambito della produzione letteraria italiana. Gli scritti, pubblicati dal 2005 al 2008 sulla rivista «Giudizio Universale» e ora collazionati in un’unica raccolta, propongono un’interpretazione originale di molti classici del canone letterario nazionale e della più significativa produzione narrativa contemporanea. Il risultato è un testo fluido, ad un…

Let T be a nonexpansive self-mapping of a closed bounded convex subset Y of a Hilbert space. For l in (0, 1), the author considers the iteration xl = lf(xl)+(1−l)Txl, where f from Y to Y is a $\phi$-contraction. Then, the author proves that (xl)l converges strongly as l goes to 0 to the unique fixed point of the $\phi$-contraction Pof, where P is the metric projection of Y onto the set FT of fixed points of T. The viscosity approximation method of the paper is obtained from the method proposed by A. Moudafi [J. Math. Anal. Appl. 241 (2000), no. 1, 46–55; MR1738332 (2000k:47085)] for mappings in Hilbert spaces, and by H. K. Xu [J. Math. Anal. Appl. 298 (2004), no. 1, 279–291; MR2086546 (2005…
The effects of canrenone on left ventricle diastolic function, left atrial compliance and on atrial natriuretic hormones in some subjects with “chall…
2010
STUDY PROPOSAL: Proposal to evaluate the response of left ventricular function of 30 patients with challenge hypertension to 50 or 100 mg of canrenone. Evaluation will be performed by repeated control of echocardiographic parameters, left atrial function and NT-proBNP. We also will use Tissue Doppler Imaging to identify and follow early left ventricular dysfunction. Careful monitoring of serum creatinine and electrolyte levels will be carried out. At the end of the study we will be able to identify the best dose of aldosterone we can recommend to control hypertension and left ventricular diastolic dysfunction. In possible successive evaluations other end points such as mortality, morbility,…
Significance of Autologous Interleukin-6 Production in the HA22T/VGH Cell Model of Hepatocellular Carcinoma
2006
Cancer cells may often support their own growth, survival, and drug resistance by autocrine/paracrine loops based on the production of different factors; results from us and others have shown that similar interleukin-6 (IL-6)-related loops are operative in multiple myeloma and prostate or renal cancer. Because this aspect has not been investigated in detail for hepatocellular carcinoma (HCC), we have examined it in HA22T/VGH cells. These differ from other primary liver cancer cell lines (that is, HepG2, HuH-6, and HuH-7) in that enzyme-linked immunosorbent assay (ELISA) showed the HA22T/VGH cells to secrete remarkable amounts of IL-6 (16.8 ng/10(6) cells/24 h); this production, due to const…
Recensione a : The story of my people di Mario Mignone

Electron transfer mechanism in Shewanella loihica PV-4 biofilms formed at graphite electrode
2012
Abstract Electron transfer mechanisms in Shewanella loihica PV-4 viable biofilms formed at graphite electrodes were investigated in potentiostat-controlled electrochemical cells poised at oxidative potentials (0.2 V vs. Ag/AgCl). Chronoamperometry (CA) showed a repeatable biofilm growth of S. loihica PV-4 on graphite electrode. CA, cyclic voltammetry (CV) and its first derivative shows that both direct electron transfer (DET) mediated electron transfer (MET) mechanism contributes to the overall anodic (oxidation) current. The maximum anodic current density recorded on graphite was 90 μA cm − 2 . Fluorescence emission spectra shows increased concentration of quinone derivatives and riboflavi…
Bioadhesive monolayer film for the in vitro transdermal delivery of sumatriptan
2006
The work presented here aims to develop a bioadhesive monolayer film containing sumatriptan as adjuvant for the treatment of headache pain in a severe migraine attack. Permeation experiments were performed from the films prepared and from the respective solution, to evaluate the relevant permeation parameters. The effect of the penetration enhancers Transcutol, 2-pyrrolidone, and polyethylene glycol 600 was evaluated. The results obtained show that Transcutol and 2-pyrrolidone decreased sumatriptan permeation from solution, whereas a modest increase was produced by polyethylene glycol 600. The enhancers produced the same effects when they were included in the film. Compared to solution, the…
El Trabajo Social, sus imágenes y su público. La construcción de una identidad colectiva.
2003
El objeto de esta tesis, consiste en responder a una cuestión ¿cuál es el lugar del Trabajo Social? desde un orden simbólico. Partimos desde la perspectiva teórica del construccionismo, presentamos un planteamiento epistemológico que implica la transición del Trabajo Social como un medio (profesión) hacia el Trabajo Social como un fin (disciplina), llevamos la investigación al espacio de un caso (serie de televisión), buscamos como analizar las representaciones sociales del Trabajo Social, a través de sus imágenes y de la influencia social de su público (audiencia).Para materializar este propósito definimos en la primer parte, los tres elementos teóricos más relevantes del objeto. En primer…
