IL TRATTATO DELL’ARTE RAPPRESENTATIVA PREMEDITATA, ED ALL’IMPROVVISO. L’ “IMPRESA BELLISSIMA E PERICOLOSA” DI ANDREA PERRUCCI
No full textIl saggio esamina il famoso trattato Dell’arte rappresentativa premeditata, ed all’improvviso,
pubblicato da Andrea Perrucci a Napoli nel 1699, noto per la ricchezza
di materiali poetici relativi alla Commedia dell’Arte. Si affrontano alcune delle tematiche
salienti che affiorano tra le regole delle due parti: l’eco del pregiudizio antiteatrale
e la giustificazione morale del palcoscenico; la drammaturgia della santita` come
forma della ‘‘perfetta tragedia’’; l’influenza del pensiero gesuitico; le fonti preferite
(Lope de Vega, Boulenger, Minturno); il metodo dell’improvvisazione, i suoi rapporti
con la retorica e l’aspirazione ad un attore ‘‘perfetto’’, capace di farsi autore del proprio
teatro. La struttura dell’opera, le apparenti contraddizioni (soprattutto nel proemio),
i riferimenti personali, le affermazioni conclusive sembrano rivelare come quel
che si intendeva dovesse essere una tradizionale ‘‘poetica’’ e` un testo critico dominato
da una pulsione autobiografica incontenibile, che e` il suo tratto piu` inquietante e gli
conferisce un’indiscutibile modernita`
Endoparasites in dogs and cats of Tuscany (Italy) and evaluation of the efficacy of the anthelmintic treatment
No full textEfficacy of an Essential Oil of Eugenia Caryophyllata Against Psoroptes Cuniculi
No full textThe acaricidal activity of Eugenia caryophyllata essential oil was evaluated in vitro and in vivo on Psoroptes cuniculi, a mange mite. In vitro, different concentrations of the oil were tested and the observed mites mortality was compared with that observed in untreated and treated (Acacerulen R®) controls. In vivo, six P. cuniculi infected rabbits were topically treated with the oil diluted at 2.5% and compared with untreated and treated control groups of six rabbits each. In vitro, up to the concentration of 0.10% the oil gave highly significant (P < 0.01) percentages of mite mortality respect to the untreated controls, but only up to 0.16% it showed the same efficacy of Acacerulen R®. In vivo, the treatment with the essential oil cured all infested rabbits and no statistical differences were observed respect to the treated control group. The untreated rabbits remained infested
Giardia duodenalis and canine parvovirus (CPV) in a toy poodle and maltese dog breeding kennel
No full textI Test dei labirinti in ambito di ricerca clinico, evolutivo e neuropsicologico: aspetti valutativi, diagnostici e riabilitativi.
No full textLa rassegna analizza le principali ricerche condotte in ambito clinico ed evolutivo attraverso i compiti basati sulla risoluzione di labirinti. Dall'originale Test di Porteus, escogitato per la valutazione dell'intelligenza, dell'adattamento sociale e dell'impulsività, ci si focalizza sullo studio della capacità, delle strategie e del locus della pianificazione delle operazioni necessarie a percorrere correttamente un labirinto; successivamente vengono analizzate le variabili che influenzano la prestazione ai labirinti, come le abilità cognitive di base, le caratteristiche di personalità, gli stati affettivi e la motivazione dei soggetti. Per ogni tipo di compito presentato sono descritti gli obiettivi della ricerca, le caratteristiche del labirinto, le modalità di somministrazione, di registrazione e analisi dei dati, nonché i risultati ottenuti

No full textHeartfelt choices: The influence of cardiac phase on free-choice actions
No full textThe influence of cardiac phases on cognitive and sensorimotor functions is noteworthy. Specifically, during systole, as opposed to diastole, there is an observed enhancement in tasks demanding the suppression of instructed responses. This suggests that systole contributes to inhibitory control in motor functions. However, the extent to which systolic inhibition is significant in volitional free-choice actions, such as choosing to execute or refrain from a cue-initiated response, remains to be clarified. To fill this gap in the current literature, the purpose of this study was to test whether during the systole phase, compared with the diastole phase, the tendency to enact volitional actions decreased due to the systolic inhibitory effect. We used a modified version of the Go/No-Go task with an added condition for volitional free-choice actions, where participants could decide whether to respond or not, to test whether systolic inhibition could affect the volitional decision to act. The results showed that participants' responses were less frequent in systole than in diastole in the volitional action condition. Then, to test the robustness of the cardiac effect on volitional actions, we used two established manipulations: the Straw Breathing Manipulation and the Cold Pressor Test, which were able to induce anxiety and increase the heart rate, respectively. Results showed that the systole/diastole difference in the number of volitional action trials in which participants decided to respond tended to remain the same despite all manipulations. Overall, our results provide convergent evidence for the effect of the heart on the decision to act, an effect that appears independent of manipulations of both the physiological and psychological state of the individual

INVOLVEMENT OF THE 'TRACTION MODEL' AS TGF-BETA1 ACTIVATION MECHANISM IN THE DEVELOPMENT OF REACTIVE FIBROSIS IN SPONTANEOUSLY HYPERTENSIVE RATS CARDIAC FIBROBLASTS.
No full textCardiac reactive fibrosis is a well-known pathological effect derived from arterial hypertension. TGF-β plays a key role in the progression from the inflammation state to the fibrosis process establishment. Nonetheless, only the active form of TGF-β is effective, and this occurs if it is unbound to the latency complex proteins (i.e. Latency Associated Protein, LAP and Latent TGF-β Binding Protein, LTBP.
In vivo and in vitro models of different fibrosis-based pathologies (e.g. pulmonary and dermal fibrosis), have highlighted a novelty in the activation of TGF–β, which occurs not only by proteolysis on latent proteins, which involves enzymes as plasmin, thrombospondin and matrix metalloproteases, but also through a non-proteolytic mechanism, defined by Keski-Oja in 2004 "Traction model". This mechanism consists in specific binding of several integrins (αVβ3, αVβ6 and αVβ5), expressed by myofibroblasts, with LAP and LTBP; contraction forces exerted by myofibroblasts are able to active latent TGF-β.
On the basis of the “traction model” are an initial production of TGF-, the conversion of fibroblast into myofibroblast, the production of α-SMA by myofibroblast and their subsequent contractile activity, the increase in ECM production and, therefore, further TGF- production, in a positive feedback mechanism, able to amplify the fibrotic process progression.
Aims of this study are 1) the development of a more fast and efficient protocol to cardiac fibroblast extraction, 2) the evaluation of possible involvement of LTBP-1 and αVβ5 integrin in development of hypertensive-induced cardiac fibrosis and so 3) the speculation about TGF-β1 mechanical activation by traction in primary cardiac fibroblasts isolated in hypertensive rats
