ortho-Metalated Dirhodium(II) Catalysts Immobilized on a Polymeric Cross-Linked Support by Copolymerization. Study of their Catalytic Activity in the…
2008
Chiral ortho-metalated dirhodium(II) compounds containing the phosphine P(p-CH2═CHC6H4)3 have been efficiently immobilized by radical copolymerization with styrene and 1,4-divinylbenzene. Their cat...

La capilla de la Virgen de Campanar en Valencia: tradición popular erigida en erudita retórica visual
2018
This chapel forms part of the parochial church of Campanar, which belongs to the municipality of Valencia. The Virgen de Campanar (Virgin of Campanar) is an image executed in alabaster, discovered on the subfloor of the church of this place on February 19th, 1596, by some construction workers who were undertaking some remodeling at that time. From that moment forward it began to be worshipped by the masses as a miraculous image. Among its alleged properties we find the mysterious fact that powder from its plaster had miraculous effects: it was taken dissolved in water to cure the sick or to assure a healthy birth for pregnant women, and it even calmed storms at sea if it was thrown into the…
La produzione di ceramica da mensa a Solunto: un esempio di continuità tecnologica dallʼetà arcaica a quella ellenistico-romana.
2009
Solunto is one of the most important Phoenician-Punic colonies of north-western Sicily. Archaeometric researches carried out in the last years ascertained a local production of transport amphorae during Archaic and Classic age (7th-5th century B.C.) through mineralogical, petrographical and chemical analysis of ceramic samples, kiln refuses and local raw materials (clays and alluvial sands). In connection with these earliest works, the present paper was focused on some specific forms of fine-tempered table ware of Archaic age and/or Classic-Hellenistic age. This pottery has been recurrently brought to light in Solunto and it is furthermore suspected to be, at least to some extent, a local r…
Participation in ICT Development Interventions: Who and How?
2016
The aim of participatory development (PD) in the context of using Information and Communication Technologies (ICT) for development (ICT4D) is to empower underprivileged communities and disadvantaged segments of the stakeholders. The literature on ICT4D is replete with empirical evidence showing that ICT interventions often fail since they are often externally initiated, with very limited involvement from the affected (Heeks, 2002). Clearly, the principles and concepts of PD are relevant to ICT4D. However, we should not consider PD a panacea but need to understand the caveats and processes by which PD happens. Questions to ask include: What are the various challenges in PD? Who are the relev…
Degassing of gaseous (elemental and reactive) and particulate mercury from Mount Etna volcano (Southern Italy)
2007
Abstract There is an urgent need to better constrain the global rates of mercury degassing from natural sources, including active volcanoes. Hitherto, estimates of volcanic fluxes have been limited by the poorly determined speciation of Hg in volcanic emissions. Here, we present a systematic characterisation of mercury partitioning between gaseous (Hg(g)) and particulate (Hg(p)) forms in the volcanic plume of Mount Etna, the largest open-vent passively degassing volcano on Earth. We demonstrate that mercury transport is predominantly in the gas phase, with a mean Hg(p)/Hg(g) ratio of ∼0.01 by mass. We also present the first simultaneous measurement of divalent gaseous mercury ( Hg ( g ) II …
Involvement of Bax and Bcl-2 in induction of apoptosis by essential oils of three Lebanese Salvia species in human prostate cancer cells
2018
Prostate cancer is one of the most common forms of cancer in men, and research to find more effective and less toxic drugs has become necessary. In the frame of our ongoing program on traditionally used Salvia species from the Mediterranean Area, here we report the biological activities of Salvia aurea, S. judaica and S. viscosa essential oils against human prostate cancer cells (DU-145). The cell viability was measured by 3(4,5-dimethyl-thiazol-2-yl)2,5-diphenyl-tetrazolium bromide (MTT) test and lactate dehydrogenase (LDH) release was used to quantify necrosis cell death. Genomic DNA, caspase-3 activity, expression of cleaved caspase-9, B-cell lymphoma 2 (Bcl-2) and Bcl-2 associated X (Ba…
Effects of a preparation containing a standardized ginseng extract combined with trace elements and multivitamins against hepatotoxin-induced chronic…
1987
A preparation containing a standardized ginseng extract which has been shown to exert anti-hepatotoxic activity in vitro, combined with trace elements and multi-vitamins was compared to placebo in 24 elderly out-patients with toxin-induced (alcohol and drugs) chronic liver disease in order to evaluate its effect on liver function. Each patient was blindly treated either with the preparation containing ginseng extract or placebo for 12 weeks. The preparation containing ginseng extract significantly modified bromsulphthalein retention and blood zinc levels when compared to pre-treatment levels and to placebo. Serum bile acids, and γ-glutamyl transpeptidase before and after a fatty meal were …
Redescription and new records of the monotypic genus Trynocoris Herring, 1976 (Heteroptera: Miridae: Cylapinae: Fulviini).
2019
Trynocoris lawrencei Herring, the only representative of the genus Trynocoris and only known from Barro Colorado Island, Canal Zone, Panama, is recorded for the first time from Mexico, Nicaragua, Panama: Chinqui and Ecuador. Redescription of the genus and species are given along with color photographs of the adults, scanning electron micrographs of selected structures of T. lawrencei. Illustrations of the tarsi and male genitalia are presented for the first time.
Pollen-induced allergic rhinitis in 1360 Italian children: comorbidities and determinants of severity
2013
BACKGROUND: Pollen-induced allergic rhinoconjunctivitis (AR) is highly prevalent and rapidly evolving during childhood. General practitioners may not be fully aware of the nature and severity of symptoms experienced by patients and might underestimate the prevalence of moderate or severe disease. Thus, the relevance of early diagnosis and intervention may be overlooked. OBJECTIVES: To investigate the severity of pollen-induced AR and its determinants in Italian children referred to allergy specialists and who had never received specific immunotherapy (SIT). METHODS: Children (age 4-18 yr) affected by pollen-induced AR who had never undergone SIT were recruited between May 2009 and June 2011…
