d.verse. Primo Festival Internazionale del Teatro per le Diverse Abilità
No full textNell’ambito delle manifestazioni per Genova 2004 Capitale Europea della Cultura, si è svolto a Genova, fra il 4 ottobre e il 26 novembre 2004, "d.verse. Primo Festival Internazionale del Teatro per le Diverse Abilità" organizzato dal Centro Studi per l’integrazione lavorativa dei disabili della ASL 3 “Genovese” in collaborazione con l’associazione culturale “la Milonga” e il Laboratorio Teatrale Integrato Tuttinscena, con il sostegno della Provincia di Genova e della Regione Liguria, il patrocinio dell'Università degli Studi di Genova, e la collaborazione di otto teatri genovesi. Responsabile: Maria Paola Ferrigno; Progettazione artistica: Cristina Valenti; Coordinamento artistico: Sandro Baldacci. In conclusione, il convegno "D.verse Abilità e Teatro", occasione che ha consentito a studiosi, attori, registi e scrittori di interrogarsi sulle nuove frontiere del teatro come strumento di integrazione e sul peculiare apporto che artisti “diversamente abili” possono dare alla rappresentazione artistica. Il cartellone ha ospitato alcune fra le più importanti compagnie di teatro integrato, e di compagnie composte da attori disabili, che operano in Italia e in Europa. Il Festival si è aperto con il musical “l’Anima Buona del Pianeta Sezuan” del Laboratorio Tuttinscena: trenta ragazzi, di cui una buona parte portatori di handicap, provenienti da dieci scuole genovesi, per la regia di M. Pirovano e M. Bonomi. A seguire: “Microphobia” e “The Human Suite”, due coreografie della CandoCo Dance Company di Londra, una compagnia di danza contemporanea formata da danzatori disabili e normodotati, leader nella formazione e nell’educazione alla danza integrata; “La Sirena di Rodari” del Laboratorio Teatrale Integrato Piero Gabrielli di Roma, per la regia di R. Gandini: tredici “ex” del laboratorio in uno spettacolo che ha dato vita alla prima Compagnia Italiana Integrata di Teatro Ragazzi; “Esopo Opera Rock”, musical per la regia di S. Baldacci, frutto di un laboratorio integrato che ha coinvolto i centri diurni della Città di Imperia, il DAMS di Genova e operatori socio sanitari; “No Exit”, regia di A. Viganò, della compagnia francese Oiseau Mouche, finanziata dallo stato e composta da attori professionisti portatori di handicap; “Ritratti” di Lenz Rifrazioni di Parma per la regia di M.F. Maestri: cinque ritratti del mito occidentale resi con eccezionale forza rappresentativa delle attrici diversamente abili ; “Filottete H” di Maccabeteatro per la regia di E. Toma: ispirato a Sofocle, lo spettacolo, con attori portatori di handicap, tratteggia la difficoltà di accettare l’idea di non essere perfetti.
A conclusione del ciclo di rappresentazioni, il convegno dal titolo "D.verse Abilità e Teatro". Interventi di E. Buonaccorsi (Università di Genova ), M.P. Ferrigno (Centro Studi della ASL 3 “Genovese”), G. Oliva (Università Cattolica di Milano), C. Valenti (Università di Bologna), A. Celestini (attore e regista), R. Frati (Teatro dell’Oppresso di Parigi), T. Scarpa (scrittore), D. Segre (regista). In chiusura: “A proposito di sentimenti”, mediometraggio di D. Segre. Il Festival si è concluso con la performance “Emplacement Reservé”, che Rui Frati ha rappresentato con i suoi attori e con il coinvolgimento diretto del pubblico presente. Le disavventure di una madre “speciale” a causa delle circostanze che coinvolgono sua figlia disabile. Un modo dinamico e vitale affinché il dibattito e l’atto teatrale siano un unico corpo

Chest wall and lung volume estimation by optical reflectance motion analysis. J. Appl. Physiol. 81(6): 2680–2689, 1996.—Estimation of chest wall motion by surface measurements only allows one-dimensional measurements of the chest wall. We have assessed an optical reflectance system (OR), which tracks reflective markers in three dimensions (3-D) for respiratory use. We used 86 (6-mm-diameter) hemispherical reflective markers arranged circumferentially on the chest wall in seven rows between the sternal notch and the anterior superior iliac crest in two normal standing subjects. We calculated the volume of the entire chest wall and compared inspired and expired volumes with volumes obtained by spirometry. Marker positions were recorded by four TV cameras; two were 4 m in front of and two were 4 m behind the subject. The TV signals were sampled at 100 Hz and combined with grid calibration parameters on a personal computer to obtain the 3-D coordinates of the markers. Chest wall surfaces were reconstructed by triangulation through the point data, and chest wall volume was calculated. During tidal breathing and vital capacity maneuvers and during CO2-stimulated hyperpnea, there was a very close correlation of the lung volumes (Vl) estimated by spirometry [Vl(SP)] and OR [Vl(OR)]. Regression equations of Vl(OR) ( y) vs. Vl(SP) ( x,btps in liters) for the two subjects were given by y = 1.01 x − 0.01 ( r = 0.996) and y = 0.96 x + 0.03 ( r = 0.997), and by y = 1.04 x + 0.25 ( r = 0.97) and y = 0.98 x + 0.14 ( r = 0.95) for the two maneuvers, respectively. We conclude spirometric volumes can be estimated very accurately and directly from chest wall surface markers, and we speculate that OR may be usefully applied to calculations of chest wall shape, regional volumes, and motion analysis. </jats:p
Optimized complex signals for Eddy Current Testing
No full textThe choice of optimized excitation devices and strategies is now interesting recent studies about Non Destructive Eddy Current Testing (ND-ECT). Recently, the attention has been paid to the use of complex excitation signals, meant as signals different from the sinusoidal ones and with wide frequency content. In particular, some studies have highlighted their suitability, respect to the sinusoidal one, in supporting the measurement, detection and quantification stages when 'difficult cases' are explored (i.e. very short or annealed cracks). Generally, two class of signal have been proposed in literature. They concern with signals that have to be analysed in the time domain and signals analysed in transformed domains. The former class is represented by signal as the pulsed or pseudo-noise, while the latter contains signal as the chirp or multi-frequency as the best candidate. The author have placed their attention to this second class of signal and in this paper they propose an experimental comparison among different realization of these excitation signals suitably designed to improve the quality of experimental data when difficult cases are experienced
Human respiratory muscle action and control during exercise.

Human respiratory muscle actions and control during exercise. J. Appl. Physiol. 83(4): 1256–1269, 1997.—We measured pressures and power of diaphragm, rib cage, and abdominal muscles during quiet breathing (QB) and exercise at 0, 30, 50, and 70% maximum workload (W˙max) in five men. By three-dimensional tracking of 86 chest wall markers, we calculated the volumes of lung- and diaphragm-apposed rib cage compartments (Vrc,p and Vrc,a, respectively) and the abdomen (Vab). End-inspiratory lung volume increased with percentage of W˙max as a result of an increase in Vrc,p and Vrc,a. End-expiratory lung volume decreased as a result of a decrease in Vab. ΔVrc,a/ΔVab was constant and independent ofW˙max. Thus we used ΔVab/time as an index of diaphragm velocity of shortening. From QB to 70%W˙max, diaphragmatic pressure (Pdi) increased ∼2-fold, diaphragm velocity of shortening 6.5-fold, and diaphragm workload 13-fold. Abdominal muscle pressure was ∼0 during QB but was equal to and 180° out of phase with rib cage muscle pressure at all percent W˙max. Rib cage muscle pressure and abdominal muscle pressure were greater than Pdi, but the ratios of these pressures were constant. There was a gradual inspiratory relaxation of abdominal muscles, causing abdominal pressure to fall, which minimized Pdi and decreased the expiratory action of the abdominal muscles on Vrc,a gradually, minimizing rib cage distortions. We conclude that from QB to 0% W˙max there is a switch in respiratory muscle control, with immediate recruitment of rib cage and abdominal muscles. Thereafter, a simple mechanism that increases drive equally to all three muscle groups, with drive to abdominal and rib cage muscles 180° out of phase, allows the diaphragm to contract quasi-isotonically and act as a flow generator, while rib cage and abdominal muscles develop the pressures to displace the rib cage and abdomen, respectively. This acts to equalize the pressures acting on both rib cage compartments, minimizing rib cage distortion . </jats:p

No full textAutomatic Recognition on Fetal Pulsed-Wave Doppler Envelope using Neural Networks
No full textPulsed-Wave Doppler (PWD) echocardiography is one of the standard techniques for antenatal cardiological diagnosis. When applied to fetuses, this technique is challenging since, beyond being intrinsically operator-dependent, different issues related to the fetal heart size, the fetal movements and the ultrasound artifacts appear. In long PWD recordings, the signal segments completely meaningful for a morphological analysis are then limited in number and duration.
In this work, a neural network-based approach for the automatic identification of the fetal beats showing the most important waves of the PWD is presented and evaluated on real signals. The proposed algorithm works on a couple of 1D signals, representing the PWD envelope extracted from the video. For the validation, a small dataset was created, including 8 records from four voluntary pregnant women (21st to 27th gestational week), 10 seconds long each. An expert cardiologist annotated the dataset. The performance of the method was evaluated through a 4-fold cross-validation scheme, revealing an average accuracy up to 87.8%. This confirms the validity of the proposed approach, laying the basis for future improvements
Computer-Aided Surgery and Immediate Loading to Rehabilitate Complete Arch with Four Dental Implants and Fixed Screw-Retained Prosthesis Up to 4 Years in Function: A Retrospective Study
No full textPurpose: The aim of this study was to analyze retrospectively the clinical reliability of complete-arch rehabilitations with screw-retained fixed prostheses supported by four dental implants inserted with a fully guided surgical protocol. Materials and Methods: All the implants were placed between December 1, 2015, and April 30, 2019. Digital implant surgical planning was performed for all the complete-arch rehabilitations, and then, fully guided surgery was performed. The fixed provisional prostheses were delivered the day of the surgery and replaced by definitive prostheses after the healing period. Patients were followed up to determine survival of the implants and success of the overall treatment. Results: A total of 160 implants were positioned in 37 patients, with three patients receiving rehabilitations in both arches. A total of 40 complete-arch rehabilitations were performed, 26 in the maxilla and 14 in the mandible. Only five implants failed, resulting in an overall implant survival rate of 96.9%. No definitive prostheses failed, resulting in a 100% prosthetic success rate. The failed implants were successfully replaced before definitive prostheses were made, resulting in an overall treatment success of 100%. Conclusion: Within the limitations of this study, digital planning and guided surgery to perform complete-arch rehabilitations on four dental implants seems to be a valid treatment option. However, several prospective studies with longer follow-up are needed to achieve more predictable results

No full textThe selective blockade of metabotropic glutamate receptor-5 attenuates fat accumulation in an in vitro model of benign steatosis
No full textIt has been previously found that the blockade of metabotropic glutamate receptor type 5 (mGluR5) protects against hepatic ischemia/reperfusion injury and acetaminophen toxicity. The role of mGluR5 in NAFLD has not yet been elucidated. Here, we evaluated the effects of mGluR5 blockade in an in vitro model of steatosis. HepG2 cells were pre-incubated for 12 h with an mGluR5 agonist, a negative allosteric modulator (DHPG and MPEP, respectively) or vehicle, then treated with 1.5 mM oleate/palmitate (O/P) for another 12 h. Cell viability was evaluated with the MTT assay; fat accumulation was measured using the fluorescent dye Nile red; SREBP- 1, PPAR-α, iNOS and Caspase-3 protein expression were evaluated by Western blot; NFkB activity was evaluated as pNFkB/NFkB ratio. mGluR5 modulation did not alter cell viability in O/P-incubated cells; MPEP prevented intracellular lipid accumulation in O/P treated cells; MPEP administration was also associated with a reversion of O/P-induced changes in SREBP-1 and PPAR-α expression, involved in free fatty acid metabolism and uptake. No changes were observed in iNOS and caspase-3 expression, or in NFkB activity. In conclusion, mGluR5 pharmacological blockade reduced fat accumulation in HepG2 cells incubated with O/P, probably by modulating the expression of SREBP-1 and PPAR-α
