MR2670689 Rezapour, Shahram; Khandani, Hassan; Vaezpour, Seyyed M. Efficacy of cones on topological vector spaces and application to common fixed poi…
2011
Recently, Huang and Zhang defined cone metric spaces by substituting an order normed space for the real numbers and proved some fixed point theorems. For fixed point results in the framework of cone metric space see, also, Di Bari and Vetro [\textit{$\varphi$-pairs and common fixed points in cone metric spaces}, Rend. Circ. Mat. Palermo \textbf{57} (2008), 279--285 and \textit{Weakly $\varphi$-pairs and common fixed points in cone metric spaces}, Rend. Circ. Mat. Palermo \textbf{58} (2009), 125--132]. Let $(E,\tau)$ be a topological vector space and $P$ a cone in $E$ with int\,$P\neq \emptyset$, where int\,$P$ denotes the interior of $P$. The authors define a topology $\tau_p$ on $E$ so tha…
On fixed points of alpha-eta-psi-contractive multifunctions
2014
Recently Samet et al. [B. Samet, C. Vetro, P. Vetro, Fixed point theorem for alpha-psi-contractive type mappings, Nonlinear Anal., 75 (2012), 2154{2165] introduced the notion of alpha-psi-contractive type mappings and established some fixed point theorems in complete metric spaces. Succesively, Asl et al. [J.H. Asl, SH. Rezapour, N. Shahzad, On fixed point of alpha-contractive multifunctions, Fixed Point Theory Appl., 2012, 212 (2012)] introduced the notion of alpha_*-psi-contractive multifunctions and give a fixed point result for these multifunctions. In this paper we obtain certain new fixed point and common fixed point theorems via alpha_*-admissible multifuncions with respect to eta. T…

2012
Recently, L. G. Huang and X. Zhang [J. Math. Anal. Appl. 332 (2007), no. 2, 1468–1476; MR2324351 (2008d:47111)] defined cone metric spaces by substituting an order normed space for the real numbers and proved some fixed point theorems. In this paper the authors prove a common fixed point theorem for four non-self-mappings in the framework of cone metric spaces. This result is an extension of a common fixed point theorem of Radenović and Rhoades for two non-self-mappings. The paper also contains some illustrative examples. For fixed point results in the framework of cone metric spaces see also [M. Arshad, A. Azam and P. Vetro, Fixed Point Theory Appl. 2009, Art. ID 493965; MR2501489 (2010e:5…
MicroRNAs in Colorectal Cancer Drug Resistance: Shooters become Targets
2013

MicroRNAs (MiRNAs) are involved in the regulation of several biological processes such as development, differentiation, metabolism, apoptosis and proliferation. Recently, it has been shown that deregulated expression of miRNAs are present in different human cancers, suggesting a potential role in carcinogenesis [1,2]. Recent evidence suggests that miRNAs may represent potential new therapeutic approaches in patients with dru…
A large view of CYP21 locus among Sicilians and other Populations: identification of a novel CYP21A2 variant in Sicily.
2011
Background. Several mutations in CYP21 locus cause 21-Hydroxylase Deficiency (21-OHD). The most common mutations are widespread among the different geographic areas and their frequencies have been also reported to differ among certain populations. Aim. To obtain a large view on the frequencies of the most common mutations in the CYP21 locus, in Sicily, in Mediterranean and in other major geographic areas in the worldwide. Subjects and Methods. 308 unrelated CYP21A2 alleles leading 21-OHD in Sicily were genetically typed and compared with other series previously reported in Sicily and in surrounding regions. An analysis of the frequencies of the different geographic areas was also carried ou…

Shared Administration for Smart Cities
2016
Within the paradigm of Smart Cities, the role played by urban communities is becoming ever more crucial. This chapter, in particular, explores the paradigm of “Shared administration” as the most effective urban governance model that helps urban communities to operate as smart communities taking care and regenerating common urban spaces. According to this administrative culture, the “Regulation for collaboration between citizens and administration” and the “Pact” are measures to implement practical opportunities to empower citizens, to free their energies and to enhance their knowledge and competences in a renewed alliance with the public institutions.
The Coronation Parliament of John III Sobieski in French-Language Reports Sent to London
2021
The coronation parliament in the former Polish-Lithuanian Commonwealth was always an exceptional event not only for the newly elected monarch but also for diplomats from foreign courts who reported about its proceedings. In their reports, they tried to provide as much information as possible, not only political but also moral, social, and related to the ceremony. Of course, such material needs careful analysis, as the diplomats, othen unfamiliar with the reality of the Polish-Lithuanian state, misrepresented the facts or presented them in a wrong context. The analysed manuscript accounts from the coronation parliament of John III Sobieski probably played the role of an additional source of …
Coesione sociale, etica ed educazione
2017
In this article, social cohesion is presented in terms of belonging, interdependence, integration, sharing, participation, but also as corresponsibility between the different actors present in a territory. The promotion of social cohesion, therefore, essentially has to do with educational interventions aimed at social inclusion. Compared to the more traditional interventions on social emergencies, supporting social cohesion means in fact enhancing relations between members of society and promoting the common good through the collective assumption of responsibility. The role of the school is crucial in this, but also of lifelong learning, therefore the Third Mission of Universities.
