Expression of Cyclooxygenase-1 and Cyclooxygenase-2 in normal and pathological human oral mucosa
2011
Abstract: Cyclooxigenase (COX) is the rate-limiting enzyme for the conversion of arachidonic acid (AA) to prostaglandins (PGs). Two isoforms of COX have been identified: COX-1 is constitutively expressed in many cells and is involved in cell homeostasis, angiogenesis and cell-cell signalling; COX-2 is not expressed in normal condition however it is strongly expressed in inflammation. The oral cavity is costantly exposed to physical and chemical trauma that could lead to mucosal reactions such as hyperplasia, dysplasia and cancer. Early diagnosis is the most important issue to address for a positive outcome of oral cancer; therefore it would be useful to identify molecular markers whose expr…

A facile way to synthesize noble metal free TiO2 based catalysts for glycerol photoreforming
2023
In this work anaerobic heterogeneous photocatalytic solar/UV light reforming of glycerol in aqueous media was performed with Pt-photodeposition and noble metal free modified TiO2 photocatalysts prepared through ball milling, a very simple and cheap coupled catalyst preparation method. Different amounts of Cu2O or 3% CuO were loaded on TiO2 using ball milling and during each run glycerol conversion, hydrogen and CO2 formed in the gas phase and 1,3-dihydroxyacetone (DHA) and glyceraldehyde (GA) in the liquid phase were determined. The results were compared with the aim to verify the effectiveness of Cu2O in replacing Pt. Using noble metal free photocatalysts, 33% glycerol conversion, 10.3% an…
Experiences with CiceRobot, a Museum Guide Cognitive Robot
2005
The paper describes CiceRobot, a robot based on a cognitive architecture for robot vision and action. The aim of the architecture is to integrate visual perception and actions with knowledge representation, in order to let the robot to generate a deep inner understanding of its environment. The principled integration of perception, action and of symbolic knowledge is based on the introduction of an intermediate representation based on Gardenfors conceptual spaces. The architecture has been tested on a RWI B21 autonomous robot on tasks related with guided tours in the Archaeological Museum of Agrigento. Experimental results are presented.
Synthetic phenomenology and high-dimensional buffer hypothesis
2012
Synthetic phenomenology typically focuses on the analysis of simplified perceptual signals with small or reduced dimensionality. Instead, synthetic phenomenology should be analyzed in terms of perceptual signals with huge dimensionality. Effective phenomenal processes actually exploit the entire richness of the dynamic perceptual signals coming from the retina. The hypothesis of a high-dimensional buffer at the basis of the perception loop that generates the robot synthetic phenomenology is analyzed in terms of a cognitive architecture for robot vision the authors have developed over the years. Despite the obvious computational problems when dealing with high-dimensional vectors, spaces wit…

«Poeni foedifragi, crudelis Hannibal, reliqui iustiores» (off. i 38) Cicerone e gli exempla a proposito delle guerre puniche
2021
In a section of the De officiis, Book i, Cicero deals with the justice of warfare. He asserts that the enemies defeated who were not cruel and savage should be spared, so the maiores utterly destroyed Carthage and Numantia (i 35). In i 38 Cicero refers to the wars undertaken by Romans, distinguishing the ones waged de imperio (as the Punic wars) from the others fighted uter esset (as the wars against Celtiberi and Cimbri): the first must be fought less cruelly, but Cicero justifies the destruction of Carthage with the sentence Poeni foedifragi, crudelis Hannibal, reliqui iustiores, probably containing a quotation from Ennius’s Annales. These passages, examined in comparison with historical …
