UNA NUOVA STRATEGIA TERAPEUTICA NEI PAZIENTI RICEVENTI TRAPIANTO DI RENE DA DONATORE VIVENTE SENSIBILIZZATI CON ANTICORPI ANTI-HLA SPECIFICI CONTRO I…
2009
Introduzione: I riceventi sensibilizzati con anticorpi anti-HLA specifici contro il donatore (ASD) hanno un elevato rischio di rigetto anticorpo e cellulo-mediato. Un nuovo approccio terapeutico è stato designato per affrontare questo problema presso il nostro centro. Materiali e metodi: Da Gennaio a Dicembre 2007, 19 pazienti con ASD hanno ricevuto un trapianto di rene da donatore vivente (11 da donatori consanguinei, 8 da non consanguinei). Tutti i pazienti hanno ricevuto un singolo trattamento plasmaferetico prima dell’intervento. La terapia di induzione prevedeva Thymoglobulin 1 mg/Kg per 3 dosi (trapianto pediatrico) o 5 dosi (ritrapianto), Zenapax 1mg/kg (2 dosi), Rituxan 375 mg/m2 (1…
L’INDICE DI RESISTENZA (IR) QUALE FATTORE PROGNOSTICO NELL’OUTCOME DEL TRAPIANTO DI RENE
2009
Introduzione Il valore diagnostico dell’’indice di resistenza renale (IR) nel post trapianto è ormai indiscusso. Nel seguente lavoro ci si propone di correlare i valori medi di indice di resistenza renale a carico dei tratti distali delle arterie interlobulari alla funzionalità renale, quale fattore prognostico nella valutazione della sopravvivenza del graft. Metodi La popolazione sottoposta a studio comprende 100 pazienti trapiantati dal gennaio 2001 al dicembre 2008, durante un follow-up medio di 12 mesi, mediante una valutazione ecodoppler del graft e del tratto distale delle arterie interlobulari.Tali dati sono stati messi a confronto con alcuni parametri di funzionalità renale quali il…
Strengthening the Social Capital in Rural Areas Through the Rural Renewal Program. A Case Study of Opole Voivodeship
2019
Opinions regarding the limited resources of the social capital in Poland are quite common. The country is particularly often referred to as a place with a lower level of organization of its inhabitants. Therefore, a change is necessary towards a greater activation of local communities and creation of social organizations aimed at solving local problems. The effective implementation of development programs may provide considerable support for the introduction of these changes. The Rural Renewal Program may serve as a particularly good example in this respect because the local community is not only the beneficiary, but mainly the initiator of the actions taken. The purpose of the paper is to …
Poly (lactic acid)/D-limonene/ZnO bio-nanocomposites with antimicrobial properties
2022
[EN] Antimicrobial films of poly (lactic acid) (PLA)/D-limonene/zinc oxide (ZnO)-based bio-nanocomposites were prepared via melt compounding and subsequent thermocompression. D-limonene was incorporated at concentrations of 10 or 20 wt%, and ZnO pure nanoparticles and those organically modified with oleic acid (O-ZnO), with an average diameter of 13.5 nm, were included at concentrations of 3, 5, and 8 wt%. The plasticizing effect of D-Limonene was corroborated by a decrease in the glass transition temperature compared to pure PLA. The presence of ZnO and O-ZnO in the PLA matrix promoted a slight increase in the degree of crystallinity due to its nucleant performance. Although ZnO and O-ZnO …
Soundless Screams: Graffiti and Drawings in the Prisons of the Holy Office in Palermo
2017
The discovery of graffiti in the early years of the twentieth century by the folklorist Giuseppe Pitré left by prisoners of the tribunal of the Spanish Inquisition in Palermo has been followed by more extensive investigations in recent years. These images and words have added a concrete and particular dimension to Sicily’s position at the crossroads of the Mediterranean. As well as images of saints and naval battles are to be found inscriptions not only in Italian, Sicilian and Latin but also in English and Hebrew. This article cross references this visual and textual evidence with the relevant archives of the tribunal in order to provide a powerful microhistory of suffering and resilience …
Voltage Profile Improvement for Soc Son's Low-Voltage Grid with High Penetration of PV Systems by Optimizing the Location of SVC Devices
2018
This paper presents a method that is applied to optimize the placement of Static VAR compensators in a real low-voltage grid in the Vietnamese territory. In this way, the voltage profile of the distribution grid turns to be improved. A heuristic method, the Binary Particle Swarm Optimization, is used to find a solution to this problem within the Matlab environment. A case study that considers a high penetration of rooftop PV systems in a branch of Soc Son distribution grid is implemented to show the efficiency of the optimization method for this specific application.
Juggler's exclusion process
2012
Juggler's exclusion process describes a system of particles on the positive integers where particles drift down to zero at unit speed. After a particle hits zero, it jumps into a randomly chosen unoccupied site. We model the system as a set-valued Markov process and show that the process is ergodic if the family of jump height distributions is uniformly integrable. In a special case where the particles jump according to a set-avoiding memoryless distribution, the process reaches its equilibrium in finite nonrandom time, and the equilibrium distribution can be represented as a Gibbs measure conforming to a linear gravitational potential.
A Procedure for the Producibility Curve Identification of a Dish-Stirling Plant, Starting from Experimental Data
2019
This article presents a procedure for the producibility curve identification of a dish-Stirling plant, starting from experimental data. The producibility data was measured, recorded, analysed, filtered and monthly aggregated. Moreover, the incidence of the ambient temperature and of the mirrors cleaning on producibility data is highlighted and a procedure to normalize the measured data in temperature and cleaning level was developed. To provide a validation of the developed procedure the producibility curves at 25 °C have been obtained and compared with the one issued by the manufacturer. The two curves are in good agreement, presenting a maximum deviation of the 7 %.
Energy needs and sustainable management of the energy cycle
2017
The issue of sustainability of the energy policies is analised in its manifold facets. An overview is given about the trend of global energy needs and energy production, analysing the geographic distribution of consumptions and the share of energy sources, on the basis of the statistics and projections published by major agencies. The issue of sustainability of the energy cycle is finally addressed, highlighting how the use of biomasses as an energy source and of hydrogen as an energy carrier are among the most promising approaches.
La Seconda Vita dell'Ambiente Costruito
2021
Il contributo inquadra i saggi, gli studi, le ricerche e progetti pubblicati sul numero 9 di AGATHÓN su ‘La Seconda Vita dell’Ambiente Costruito’, tema di interesse per il mondo accademico, delle professioni e dell’industria. Cambiamenti climatici, eccessivo consumo di suolo e di risorse non rinnovabili, produzione sempre crescente di rifiuti, emergenza pandemica e crisi socio-economica globale sono entrati di fatto nel nostro quotidiano: seppur drammatiche, per certi versi, tali questioni possono essere colte come un’opportunità per ripensare il modo e il mondo in cui viviamo. In questo contesto di ‘rivoluzione’(Floridi, 2020) e di ‘policrisi’ (Losasso, 2020), e con riferimento specifico a…
