Bendamustine in association with rituximab for first-line treatment of diffuse large B-cell lymphoma in frail patients ineligible for R-CHOP/R-CHOP-like treatments
No full textR-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) has been considered the standard of care for diffuse large B cell lymphoma (DLBCL) patients, including in the elderlies, and represent the current standard treatment. Ineligibility for R-CHOP-like treatments seems to be associated with shorter survival. Recent studies have shown that bendamustine and rituximab is linked, in elderly patients affected by DLBCL. Here we report our experience with BR in 40 elderly frail patients affected by DLBCL ineligibles for R-CHOP. The OOR was 77.5%, with 22 complete responses and 9 partial responses statistical analysis showed no significant difference in overall survival (OS) between patients aged 80 years and older and patients younger than 80 years (6·4 vs. 10·2 months, respectively, P = 0·43). Complete responders were more likely patients with good performance status, (ECOG 0-1) 13 patients (60%), 9 patients (40%) were ECOG 2; of the 9 patients who achieved partial response, 7 patients had ECOG 0-1 and 2 patients had ECOG 2. Four patients had stable disease. Progression-free survival (PFS) median PFS was 13.5 months. These preliminary results showed that bendamustine and rituximab has been associated with high response rates, acceptable toxicity in frail DLBCL patients and high rate of OSS. In older patients with advanced IPI scores, no significant difference in OS were observed between patients aged 80 years and older and patients younger than 80 years. We conclude that bendamustine and rituximab seems to be a reasonable alternative for frail DLBCL patients

Architettura religiosa nei castelli normanni di Sicilia e la fruizione e valorizzazione della chiesa dei Santi Filippo e Giacomo nel castello di Maredolce a Palermo
No full textIl saggio riporta i contenuti del mio abstract per il convegno “Fortificazione, memoria, paesaggio”, promosso in occasione dei Cinquant’anni di attività dell’Istituto Italiano dei Castelli, onlus, 1964-2014. Bologna 27-29 novembre 2014. Il convegno è stato organizzato dall’Istituto Italiano dei Castelli Onlus, dal Dipartimento di Storia Culture Civiltà Alma Matere Studiorum – Università di Bologna. Il saggio indaga l’architettura religiosa presente nei castelli normanni di Sicilia, quale espressione della cultura del tempo, pienamente incarnata nelle specifiche esigenze dell’architettura militare. In particolare nel saggio è studiata la chiesa dei Santi Filippo e Giacomo, con i suoi restauri e anche con i suoi recenti interventi per la fruizione e valorizzazione anche progettati da chi scrive.The abstract summarizes the contents of my speech at the Study Conference "Fortification conference, Memory, Landscape", held on the occasion of the fifty years of activity of the Institute Italian Castle, onlus, 1964-2014, Bologna 27 to 29 november 2014. The conference was organized by the Institute Italian Caste Onlus, from the Department of History Culture Civilization Alma Mater Studiorum - University of Bologna. The essay explores the religious architecture found in Norman castles of Sicily, as an expression of the culture of the time, fully embodied in the specific needs of military architecture. I, especially in the essay studied the Church of Saints Filippo and Giacomo, with its restoration and even with its recent interventions for the reuse and development also designed by the writer

Robust, Fast and Accurate Solution of the Direct Position Analysis of Parallel Manipulators by Extra-Sensors
No full textParallel manipulators (PMs) are closed kinematic chains with one or more loops where only some pairs are actuated while the remaining are passive. In particular, they feature a fixed link (base) and an output moving link (platform) interconnected by at least two independent kinematic chains (legs) to form one loop. The most well known and commonly employed PMs (hereafter called UPS-PMs) feature n variable-length legs of type UPS (where U, P and S are for universal, spherical and prismatic pairs respectively). Equivalently, a revolute pair R could be used instead of the prismatic pair P in order to make the leg length variable (in this case the leg would be of type URS). These leg topologies provide the platform with six degrees of freedom with respect to the base.
Although the definition of UPS-PMs requires n  2, in practice, neglecting overconstrained and redundantly-actuated manipulators, performance issues recommend 3  n  6. Indeed, UPS-PMs with only two UPS legs might exhibit a low stiffness against torques acting along the line joining the centers of the two spherical pairs, and their control would require the in-series placement of at least three actuators/sensors (one of them placed to control/measure at least one out of the three degrees of freedom of the spherical pairs) which reduces the overall manipulator dynamic and accuracy capabilities. On the other side, the use of more than six legs reduces the exploitable manipulator workspace for the increase of leg interference.
Different sub-classes of manipulator architectures can be obtained according to the location of the centers of the U and S pairs in the base and in the platform respectively (Innocenti & Parenti-Castelli, 1994; Faugere & Lazard, 1995). General UPS-PM architectures feature distinct joint centers. Special architectures can be devised by setting some of the joint centers to be coincident.
A schematic of a 6-DOF UPS-PM having six legs (n = 6) and general architecture is shown in Fig. 1. In the figure, the U pairs (connecting the legs to the base) and S pairs (connecting the legs to the platform) are depicted as grey and white dots respectively. Points Bi and Pi (i = 1, ..., 6) represent the centers of the U and S pairs of the i-th leg on the base and on the platform respectively. The six legs of type UPS are represented by the telescopic rods BiPi (i = 1, ..., 6). Accordingly, the length of the i-th leg is defined as the distance li = Pi - Bi.
Manipulators with less than six DOF can be obtained from UPS-PMs by suitably eliminating or locking some of the leg kinematic pairs. For instance, considering a 6-DOF UPS-PM having six legs, elimination of four P pairs yields a 2-DOF PM having two legs of type UPS and four legs of type US.
Well-known examples of UPS-PMs are as follows: 1) the 6-DOF UPS-PMs (Gough & Whitehall, 1962; Stewart, 1965; Cappel, 1967); 2) the 3-DOF spherical PMs (Innocenti & Parenti-Castelli, 1993); 3) the 2-DOF spherical PMs (Vertechy & Parenti-Castelli, 2006); and 4) the 1-DOF helicoidal PMs (Jacobsen, 1975). Because of their parallel architecture, UPS-PMs exhibit large payload-to-weight ratio, high accuracy, high structural rigidity and high dynamic capabilities, which make them excel as: a) fast and high precision robots in vehicle simulators (Gough & Whitehall, 1962; Stewart, 1965; Cappel, 1967), machine tools (Charles, 1995) and positioning systems (Schmidt-Kaler, 1992); b) passive Cartesian input devices in joysticks, master-slave teleoperation systems (Daniel et al., 1993) and other tracking devices (Geng & Haynes, 1994); c) force/torque sensors and generators in multi-axis sensors and motors (Gaillet & Reboulet, 1983; Nguyen et al., 1991; Lewis et al., 2002); d) mechanical transmissions in motion converters (Jacobsen, 1975); and e) orthopedic devices in fixations systems (Taylor & Taylor, 2000; Di Gregorio & Parenti-Castelli, 2002).
