Existence Results for Periodic Boundary Value Problems with a Convenction Term
2020
By using an abstract coincidence point theorem for sequentially weakly continuous maps the existence of at least one positive solution is obtained for a periodic second order boundary value problem with a reaction term involving the derivative \(u'\) of the solution u: the so called convention term. As a consequence of the main result also the existence of at least one positive solution is obtained for a parameter-depending problem.
Common Fixed Point of Generalized Contractive Type Mappings in Cone Metric Spaces
2011
We obtain common fixed points and points of coincidence of a pair of mappings satisfying a generalized contractive type condition in cone metric spaces. Our results generalize some well-known recent results in the literature.
Phosphatidylserine liposomes reduce inflammatory response, mycobacterial viability and HIV replication in coinfected human macrophages
2021
AbstractChronic immune activation is the key pathogenetic event of Mycobacterium tuberculosis-human immunodeficiency virus (HIV) coinfection. We assessed the therapeutic value of phosphatidylserine-liposome (PS-L) in an in vitro model of M. tuberculosis-HIV coinfection. PS-L reduced nuclear factor-κB activation and the downstream production of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and IL-6 in bacille Calmette-Guérin-infected macrophages and of TNF-α and IL-1β in M. tuberculosis-infected and M. tuberculosis-HIV–coinfected macrophages. Importantly, a significant reduction of intracellular M. tuberculosis viability and HIV replication were also observed. These results suppor…
Rapidly growing mycobacteria in TB/HIV co-infection: a report of two cases focusing on difficulties in diagnosis and management.
2012
Recent reports indicate an increase in rates of infection and disease due to rapidly growing mycobacteria (RGM) in patients with pre-existing chronic lung disease. Studies have described difficulties in correctly identifying closely related species, even when proper methodologies are adopted, and several different gene targets have been proposed. We describe two cases of RGM infection in a 29-year-old HIV-1 positive Congolese man and a 19-year-old HIV-1 positive Liberian woman, respectively, both with bronchiectasis due to previous Mycobacterium tuberculosis (MTB) infection. Mycobacterium porcinum and Mycobacterium bolletii were identified in bronchoalveolar lavage fluid and sputum, respect…

L'osmosi tra mafia, politica ed economia
2012
Nel distinguere tra aree tradizionali e non tradizionali dell’espansione mafiosa si suole indicare come nel primo caso il potere delle mafie si configuri innanzitutto come un dominio di tipo politico-militare che si avvale di quella estesa rete relazionale, altrimenti definita sotto l’accezione di capitale sociale. Nel secondo caso, la caratteristica prevalente della mafia è quella di una pervasiva penetrazione e diffusione all’interno del tessuto economico-produttivo. Questa tipologia finisce spesso per corroborare la tesi del contagio. Al momento in cui le mafie penetrano – con i loro capitali, i loro traffici illegali e la loro organizzazione militare – all’interno della cosiddetta “part…
The nearest X-ray emitting protostellar jet observed with HST
2009
The HH 154 jet coming from the YSO binary L1551 IRS5 is one of the closest (about 150 pc) astrophysical jet known. It is therefore a unique laboratory for studies of outflow mechanisms and of the shocks forming at the interaction front between the expanding material and the ambient medium. The substructures (knots) observed within the HH 154 jet were imaged in several spectral bands using the Hubble Space Telescope. This allows us to derive a simple characterization of the physical conditions in different structures as well as to measure the proper motion of the knots in the jet, their flux variability and shock emission over a time base of about ten years. These knots in the jet undergo si…
I Sicani nel IV secolo a.C.: osservazioni su alcuni ripostigli monetali degli inizi del IV sec. a.C.
2015
This contribution intends to compare the historical testimonies relating to the Sicanians in the 4th century BC with the data deriving from the analysis of the coins found in the sites of the hinterland of Sicily and, in particular, in those falling within the territory of the current province of Caltanissetta
Gli Indigeni e la moneta. Rinvenimenti monetali e associazioni contestuali dai centri dell’entroterra siciliano
2012
The Sicilian hinterland and, in particular, the territory of the current province of Caltanissetta, during the archaeological investigations of the last sixty years, has returned a substantial monetary documentation. The analysis of these coins, conducted in parallel with that of the materials found in the relative archaeological contexts, has allowed us to draw significant considerations on the "monetary uses" of the anellenic populations of this part of Sicily. Despite, starting from the last twenty-five years of the fifth century a. C., coins spread more and more in this territory, it seems that these communities never fully understood the original structure of this exchange instrument a…
