Rastelli procedure for repair of transposition of the great arteries [S, D, L] complex.
No full textTransposition of the great arteries with [S, D, L] segmental anatomy is a rare complex congenital heart lesion. The morphologic features of this unusual disease make surgical repair more challenging than in [S, D, D] transposition. Here reported is the experience with the surgical treatment of this pathologic condition in 2 patients presenting with significant associated anomalies of the right side of the heart and pulmonary outflow tract. Relevance of the specific anatomic features of the transposition [S, D, L] complex is reviewed in terms of feasibility of biventricular repair using the Rastelli operation
Preparation and biodegradation of clay composites of PLA
No full text[EN] Purpose: Perspective applications of nanocomposites in biomedical applications are investigated in this work by producing intercalated dispersions of clays into a biodegradable polymer matrix. Poly(lactic acid) (PLA) was selected being produced from renewable resources and approved by the Food and Drug Administration for medical use.
In order to improve PLA mechanical properties and to accelerate its degradation, different layered silicate nanoclays are added: montmorillonites and fluorohectorites, without or with organic modifiers. Preparation, characterization, mechanical properties and biodegradation in blood plasma are evaluated. Results: New biodegradable materials were obtained, with improved mechanical properties (Young modulus, Peak stress and Strain at break) and with increased degradation rate (weight loss and lactic acid release).Nieddu, E.; Mazzucco, L.; Gentile, P.; Benko, T.; Balbo, V.; Mandrile, R.; Ciardelli, G.

Cosa è una vita se non viene raccontata? Intrecci temporali in La lunga attesa dell’angelo di Melania Mazzucco
No full textLa lunga attesa dell’angelo è la rivisitazione romanzata della vita di Jacomo Robusti detto Tintoretto e della figlia Marietta detta Tintoretta che nell’Ottocento era un vero e proprio mito. La storia si svolge in un felice equilibrio tra fantasia e puntigliosa documentazione che Melania Mazzucco ha effettuato su antiche carte contenute in archivi custoditi in diverse città. La storia individuale di Tintoretto fa parte di un epos collettivo, di un affresco generazionale del Cinquecento veneziano : è un romanzo corale in cui voci e comportamenti si intrecciano, dando alla narrazione una forma plurifocalizzata attraverso l’adozione dei punti di vista dei diversi personaggi. A questi si aggiunge un autore che muove i fili della narrazione e che spesso si azzera nel proprio oggetto (Tintoretto) fino a confondersi in un’unica soggettività. Ne consegue l’abolizione del distacco prospettico dell’autore e una sua immersione nel flusso del raccontoWhat is a life if it is not told ? Temporal framework in La lunga attesa dell’angelo by Melania Mazzucco · La lunga attesa dell’angelo is the fictional revisiting of Jacomo Robusti’s life, known as Tintoretto, and of his daughter Marietta, known as Tintoretta, who was a real myth in the Nineteenth century. The story strikes a felicitous balance between fantasy and meticulous documentation work carried out by Melania Mazzucco on ancient papers contained in archives of different cities. The individual history of Tintoretto is part of a collective epos, thus outlining a Sixteenth-century Venetian generational fresco. It is a choral novel in which voices and behaviors intertwine, giving the narration a multi-focused form through the adoption of the different characters’ points of view. To these characters, an author who moves the threads of narration is added. Indeed, Mazzucco often resets herself in her own object (Tintoretto) to the extent that they often merge into a single subjectivity. As a consequence, the detachment of the author’s perspective is abolished and we assist to her immersion in the flow of the stor
