Design and modelling a of bimodal camera system
2021
In computer vision, researchers face a challenging concern due to the limited field of view (FoV) when using standard cameras in capturing scenes. This problem of narrow FoV often encountered within applications that involve tasks which are related to the robot vision. Many authors have attempted, in different approaches, to solve this issue by fusing two cameras. However, they failed to improve the registration and fusing errors, where the obtained results still limited and not accurate enough. To deal with this limitation and decrease these errors, we propose a new method of camera calibration based on Interior-Point Optimisation (IPO) algorithm using transformation matrix estimation. Thi…
Safety and efficacy of irinotecan plus high-dose leucovorin and intravenous bolus 5-fluorouracil for metastatic colorectal cancer: pooled analysis of…
2005
Abstract Background A biweekly regimen of irinotecan 200 mg/m2 on day 1 and levo-leucovorin (LV) 250 mg/m2 plus 5-fluorouracil (5-FU) 850 mg/m2 via intravenous bolus on day 2 was assessed in 2 consecutive randomized trials in metastatic colorectal cancer (CRC). Patients and Methods Individual data of 254 patients were merged, and baseline features potentially affecting overall response rate (ORR), progression-free survival (PFS),overall survival (OS), and occurrence of severe toxicity were analyzed by univariate and multivariate analyses. Results In the pooled series, ORR was 33% (95% confidence interval [CI], 27%-39%). Liver-only disease (47% vs. 25%; P = 0.0012) and absence of previous we…
Morphological and biomolecular characteristics of subcentimetric invasive breast carcinomas in Sicily: A multicentre retrospective study in relation …
2012
Little information from clinical trials is available regarding the efficacy of trastuzumab treatment in subcentimetric breast carcinomas (BCs). The aim of this study was to verify the existence of correlations between HER2 and hormone receptor status, Ki67 values, grade, histotype and node involvement in a cohort of pT1a,b BCs from an area not widely covered by screening campaigns. A total of 410 pT1a,b BC formalin-fixed paraffin-embedded samples collected from eight Sicilian Anatomo-Pathological Units (APUs) were classified according to the WHO classification and tumour grading was established. Estrogen and progesterone receptor status, Ki67 labelling index and HER2 status were available. …
Oxaliplatin, irinotecan, and fluorouracil/folinic acid in advanced gastric cancer: a multicenter phase II trial of the Southern Italy Cooperative Onc…
2009
Purpose: This phase II trial assessed the tolerability and efficacy of a triplet of oxaliplatin, irinotecan, and fluorouracil/folinic acid in advanced gastric cancer. Methods: Patients with unresectable or metastatic gastric cancer, unexposed to palliative chemotherapy, received oxaliplatin 85 mg/m 2 iv and irinotecan 150 mg/m2 iv on day 1, 6S-folinic acid 250 mg/m2 iv and fluorouracil 750 mg/m2 iv on day 2, every 2 weeks. Response rate (RR) was assessed after a minimum of four cycles, and treatment continued up to 12 cycles. Results: Sixty-three patients were treated, with a median of eight (range 1-12) cycles/patient. Two complete and 19 partial responses were registered (RR 33% [95% CI, …
Cetuximab rechallenge in metastatic colorectal cancer patients: how to come away from acquired resistance?
2012
Background: Scientific data provide the evidence that secondary K-RAS mutations do not occur during anti-epidermal growth factor receptor therapy in colorectal cancer patients. This multicenter phase II prospective study aims to investigate the activity of a retreatment with a cetuximab-based therapy. Patients and methods: We enrolled 39 irinotecan-refractory patients who had a clinical benefit after a line of cetuximab- plus irinotecan-based therapy and then a progression of disease for which underwent a new line chemotherapy and finally, after a clear new progression of disease, were retreated with the same cetuximab- plus irinotecan-based therapy. Results: Median number of therapeutic li…
Heterogeneity of KRAS, NRAS, BRAF and PIK3CA mutations in metastatic colorectal cancer and potential effects on therapy in the CAPRI GOIM trial
2015
Background: Evidence suggests that metastatic colorectal carcinoma (mCRC) has a high level of intratumor heterogeneity. We carried out a quantitative assessment of tumor heterogeneity for KRAS, NRAS, BRAF and PIK3CA mutations, in order to assess potential clinical implications. Patients and methods: Tumor samples (n = 182) from the CAPRI-GOIM trial of first-line cetuximab + FOLFIRI in KRAS exon-2 wild-type mCRC patients were assessed by next-generation sequencing that allows quantitative assessment of mutant genes. Mutant allelic frequency was normalized for the neoplastic cell content and, assuming that somatic mutations usually affect one allele, the Heterogeneity Score (HS) was calculate…
Creativity, Comparison and Sharing in the Co-Creation of the Communication Campaign
2022
In the fourth chapter the evolution of Oltre's online campaign will be transversally analysed, focusing on the path of awareness acquisition by the second-generation youth involved in the co-creation process of the campaign. Afterwards, we will be analysing in detail the backstage of the creation of content. Through the participatory method, we will be highlighting how the content creators of our campaign selected the themes and the perspective from which to deal with them. We will be underlying how the content creators dismantled the circulating representation and built a counter-narrative or an alternative narrative and converted the idea, through a process of creative co-construction, in…
Backward frequency doubling of near infrared picosecond pulses.
2014
We report on backward second-harmonic generation using ps laser pulses in congruent lithium niobate with 3.2 µm periodic poling. Three resonant peaks were measured between 1530 and 1730 nm, corresponding to 16th, 17th and 18th quasi-phase-matching orders in the backward configuration, with a conversion efficiency of 4.75 x 10(-5%)/W for the 16th order. We could also discriminate the contributions from inverted domains randomized in duty-cycle.
