TGF-β/VEGF-A Genetic Variants Interplay in Genetic Susceptibility to Non-Melanocytic Skin Cancer

2022

Differential genetically determined expression of transforming growth factor-β (TGF-β pathway and of vascular endothelial growth factor-A (VEGF-A) might modulate the molecular “milieu” involved in the etio-pathogenesis of non-melanoma skin cancer (NMSC). We have evaluated the frequency of some functionally relevant SNPs of TGF-β and VEGF-A genes in 70 NMSC patients and 161 healthy controls, typed for TGF-β1 rs1800471, TGF-β2 rs900, TGF-βR1 rs334348 and rs334349, TGF-βR2 rs4522809 and VEGF-A rs3025039 SNPs. TGF-βR2 rs1800629G allele and related genotypes were found to be associated with a possible protective role against NMSC, whereas VEGF-…

Economie locali

2018

Le economie locali in Sicilia riflettono un territorio granulare in termini di determinanti spaziali, economici e sociali. Le metriche locali riflesse sulle piccole e medie imprese locali non riflettono sempre pienamente la gerarchia della dimensione della popolazione delle aree metropolitane di Palermo, Catania e Messina, confermando una diversa dinamica in termini di attività economiche. La strategia di specializzazione intelligente (S3), ancora presto apre una nuova visione per intervenire e ridurre il divario economico e sociale rispetto ad altre regioni europee L'introduzione del modello a elica Quintupla con l'inclusione della variabile ambientale, indica un modo migliore per creare c…

The challenge of a place-based and network approach to the development in the territories

2016

This paper investigates the role of research networks inside local development processes to increase the competitiveness of underdeveloped territories. This paper, within the scope of local development theory, aims to describe the state of the art on the regional research systems resulting largely from programs co-financed between 2000 and 2013, with which the various regions are preparing to engage in programming for the period 2014-2020. The extent of consistency between the objectives of sectorial specialization set by policies previously or currently implemented and those in the planning phase (S3) is assessed, as is their connection with existing territorial specializations at a region…

LA COMPLESSA STRADA VERSO L’INNOVAZIONE NEI TERRITORI

2015

This paper provides a framework on regional research systems, through which, different regions are preparing to engage in program- ming period 2014 – 2020. It will also cover the regions’ investments in the co-financed programs between 2000 and 2013. Particular attention is dedicated to those projects that, in the specific objectives or specific actions have referred to high-tech districts, techno- logical platforms, clusters, innovation centers, science or technology parks and networks. It then carries out two verifications: firstly, of the degree of consistency between policies and implementation and ongoing design (S3) and secondly of their connection with the existing territorial specia…

Un approccio place-based per lo sviluppo di sistemi regionali di ricerca in Italia

2017

This work has three objectives. The first is the creation of an extensive mapping of technological districts, innovation poles, excellence research centres, laboratories and science parks in the Italian regions. The second is about monitoring, employing data from Open Cohesion, the state of the art of regional and national programs that aim at building local research networks and innovation networks. The third objective is to compare the sectoral priorities chosen by Regions according to their Smart Specialization Strategy (S3) with the existing sectors in their research networks. Finally, the study explores to what extent the presence of the industrial districts in the regions has facilita…

On rural development of NUTS 2 and 3: a non parametric approach of distribution dynamics analysis

2008

This work presents a study about dynamics of territorial gaps in agriculture between EU NUTS 2 and 3 from three perspectives: agricultural production model, rural development and productivity. Our choice of methodology is driven by two considerations. First of all, different performances in agriculture of EU areas may lead to multimodal distributions of indicators, and this implies that no significant average behaviour a parametric estimates refers to can be identified. Secondly, even if one wants to highlight multimodality within distributions, techniques like univariate density estimates can not catch intra-distribution dynamics which lead to the formation of "poles" of units showing a "s…

Power Bus Management Techniques for Space Missions in Low Earth Orbit

2021

In space vehicles, the typical configurations for the Solar Array Power Regulators in charge of managing power transfer from the solar array to the power bus are quite different from the corresponding devices in use for terrestrial applications. A thorough analysis is reported for the most popular approaches, namely Sequential Switching Shunt Regulation and parallel-input Pulse Width Modulated converters with Maximum Power Point Tracking. Their performance is compared with reference to a typical mission in low Earth orbit, highlighting the respective strengths and weaknesses. A novel solar array managing technique, the Sequential Maximum Power Tracking, is also introduced in the trade-off a…

VEGF and Notch Signaling in Angiogenesis

2015

The vascular system is responsible for providing every cell in vertebrate organisms with a sufficient supply of oxygen and nutrients, allowing waste disposal as well as transmitting immune responses among other functions. Thus, every tissue and organ requires an efficient network of blood vessels, which can be formed de novo (vasculogenesis) or from existing vessels (angiogenesis). The onset of the latter, namely endothelial cell (EC) sprouting, is the focus of this chapter. EC sprouting starts with the differentiation of ECs into guiding tip cells and proliferative stalk cells that form the growing sprout and it ends with the so-called anastomosis, when the sprout fuses with another sprout…

Preparation and characterisation of optical and optoelectronic devices based in two-dimensional semiconductors

2020

In the Materials Science field, two-dimensional materials have gained the scientific community attention in recent years. The change and the appearance of novel properties when their thickness is reduced to nanometric scale has special interest for its fundamental properties study for, from this base, the design and its implementation in devices. The wide variety of materials with the possibility of being exfoliated at the two-dimensional level opens the field to different applications, from optoelectronic devices, detection and sensing, energy storage, catalysis, medical applications and quantum information technologies, among others. This thesis gathers results in both directions: a funda…
