Whole genome sequencing of the black grouse (Tetrao tetrix): reference guided assembly suggests faster-Z and MHC evolution

2014

Background The different regions of a genome do not evolve at the same rate. For example, comparative genomic studies have suggested that the sex chromosomes and the regions harbouring the immune defence genes in the Major Histocompatability Complex (MHC) may evolve faster than other genomic regions. The advent of the next generation sequencing technologies has made it possible to study which genomic regions are evolutionary liable to change and which are static, as well as enabling an increasing number of genome studies of non-model species. However, de novo sequencing of the whole genome of an organism remains non-trivial. In this study, we present the draft genome of the black grouse, wh…

DECORIN EFFECTS ON PROTEOMIC PROFILING OF BREAST CANCER CELLS: AN UPDATED STUDY

2015

The malignant carcinomas are characterized by several capabilities acquired by the neoplastic cells, among which the ability to invade the extracellular matrix (ECM) and to establish a crosstalk with several ECM components. Under this respect, the extracellular microenvironment is an entity extraordinarily rich of information with opposite signals. Our group has long undertaken the study of the effects of ECM molecules on the behavior of cancer cells in vitro. Among the studied molecules, the decorin was found to exert a non-permissive effect on the growth and motility of the transfected tumor cells. The decorin, belongs to the family of small leucine-rich proteoglycans (SLRP) and is involv…

The malignant carcinomas are characterized by several capabilities acquired by the neoplastic cells among which the ability to invade the extracellular matrix (ECM) and to establish a crosstalk with several ECM components. Under this respect the extracellular microenvironment is an entity extraordinarily rich of information with opposite signals. Our group has long undertaken the study of the effects of ECM molecules on the behavior of cancer cells in vitro. Among the studied molecules the decorin was found to exert a non-permissive effect on the growth and motility of the transfected tumor cells. The decorin belongs to the family of small leucine-rich proteoglycans (SLRP) and is involved physiologically in the fibrillogenesis of collagen. In the last few year a new anti-oncogenic role has been proposed for decorin1. This study aimed to implement the knowledge on the effects of ectopic decorin on breast cancer cells using as a reference point the results already achieved by our research group2 on the experimental model format. By breast cancer cell line 8701-BC and its transfected clone DEC-C2. The extension of the proteomic analysis combined with the mass spectrometry allowed to triplicate the number of identified proteins in our model. Among the newly identified proteins were members of the classes of metabolic enzymes S100 family and cell motility proteins which revealed a net decrease in the decorin transfected cells. Of considerable importance is the observation that these classes of proteins are the most involved in metastatic progression. These results confirm and reinforce the anti-oncogenic role hypothesized for decorin. The work was co-funded by the Italian 5x1000 to COBS.DECORIN

L’innovazione tecnologica e il Faculty Development.

2023

La crisi pandemica ha accelerato la diffusione di ambienti di apprendimento caratterizzati dall'uso intensivo della tecnologia. Questa novità rappresenta un obiettivo trasversale della professionalizzazione del docente universitario, con una particolare declinazione sul versante pedagogico-didattico-valutativo quale questione strategica per lo sviluppo dell’alta formazione. Il contributo illustra i risultati di una ricerca condotta con 119 docenti universitari neoassunti e 20 Direttori di dipartimento. La finalità della ricerca è stata, da una parte, rilevare la percezione dei docenti neoassunti relativa alle proprie competenze didattiche, metacognitive e valutative, con riferimento alla di…

The pandemic crisis has accelerated the diffusion of learning environments characterized by the intensive use of technology. This novelty represents a transversal objective of the professionalization of the university teacher with a particular declination on the pedagogical-didactic-evaluation side as a strategic issue for the development of higher education. This paper presents the results of research conducted with 119 newly recruited university teachers and 20 Department Directors. The aim of the research was on the one hand to detect the perception of newly hired teachers related to their teaching metacognitive and evaluative skills with reference to distance learning to highlight specific characteristics that could have encouraged or hindered adaptation to this new condition. On the other hand through the qualitative research the aim has been to penetrate in depth the challenges posed by the digital revolution at University by carrying out 20 interviews with privileged witnesses who represent on the national scene agents of institutional change. The results showed a certain awareness of the need to integrate new ways of teaching to increase interest participation and enthusiasm for technology.Settore M-PED/03 - Didattica E Pedagogia Speciale

Abitare nel reale. Dalla crisi della periferia alla tessitura di nuove relazioni contestuali

2019

I progetti redatti per “Palermo Sud-Est” sono il risultato di un Laboratorio di Laurea strutturatosi attraverso incontri, seminari, comunicazioni specialistiche, esposizioni critiche, che – in una strategia condivisa – ha visto ogni studente elaborare il proprio lavoro nel confronto con gli altri attori del Laboratorio stesso. La ricerca sui “progetti urbani” è stata impostata di modo che ogni laureando fosse messo a conoscenza dei progetti svolti nello stesso ambito territoriale dai colleghi che l’avevano preceduto, così da poter operare in continuità e contribuire a formulare un ragionamento unitario, nel quale ogni progetto costituisse continuazione, verifica o anche variante dei precede…

The projects prepared for "Palermo South-East" are the result of a Graduate Laboratory structured through meetings seminars specialist communications critical exhibitions which - in a shared strategy - saw each student elaborate their work in comparison with others actors of the same Laboratory. The research on "urban projects" was set so that each graduating student was made aware of the projects carried out in the same geographical area by the colleagues who had preceded it so as to be able to operate in continuity and contribute to formulating a unitary reasoning in which each project constituted continuation verification or even variant of the previous ones. These coordinated works have pursued two fundamental objectives: the strengthening of infrastructures and the establishment of specialized public buildings with superior functions aimed at requalifying and regenerating various critical situations with particular attention to the relationship between context and life scenarios. Thus each designer while dealing with a main functional program simultaneously deals with various issues such as the rationalization of the road system the redevelopment of existing buildings the design and refunctionalization of urban services (for example the transformed Central Station in the hotel or the project of a great Mosque)several degree theses have addressed as the main theme or as a question in the background the design of a new bed for the Oreto river and the relative establishment of a park facing it. In this desire to "patch up the wounds" in the different areas of "Palermo South-East" in close relationship with the vicissitudes of the place there is a continuous reference to architectures of all time and some questions involving the functional program are suggested - that identifies the character (or perhaps "type") of what is to be inserted in a given context - and the qualities of living reality as a pivotal material in the design process.Settore ICAR/14 - Composizione Architettonica E Urbana

Non-interleaved Quadtree Node Codification

2004

The usual quadtree node non-pointer codification is based on interleaved binary representations of node coordinates, in such a way that every operation that concerns to the spatial position or to the specific orientation of the region represented by the node needs to undo this interleaving process. So, the computation time of such operations is linear with the node depth. In this paper an alternative codification is presented called “non-interleaved codification”. The new codification has a simpler management and a higher intuitiveness than current codifications that use the interleaving approach. The proposed codification is more efficient than previous ones for the following set of operat…

Bounded Computational Capacity Equilibrium

2010

We study repeated games played by players with bounded computational power, where, in contrast to Abreu and Rubisntein (1988), the memory is costly. We prove a folk theorem: the limit set of equilibrium payoffs in mixed strategies, as the cost of memory goes to 0, includes the set of feasible and individually rational payoffs. This result stands in sharp contrast to Abreu and Rubisntein (1988), who proved that when memory is free, the set of equilibrium payoffs in repeated games played by players with bounded computational power is a strict subset of the set of feasible and individually rational payoffs. Our result emphasizes the role of memory cost and of mixing when players have bounded c…
