Fatty acids, sterols and antioxidant compounds of minor and neglected cultivar of Sicilian virgin olive oils

2007

Acidic and sterol composition, pigment fraction and antioxidant compounds (tocopherols, total phenols and polar phenols) from eight monovarietal Sicilian olive oil samples, analyzed during the crop seasons from 2003/2004 to 2005/2006, are reported. Cultivars were divided, according to their diffusion, in main, minor and neglected cultivars. Encouraging data were observed for minor and neglected cultivars, for some revaluation in regard to their relevance, because they showed the highest content in tocopherols, in total phenols and polar phenols compared with main cultivars.

Sedimentary record of anthropogenic contaminants (trace metals and PAHs) and organic matter in a Mediterranean coastal area (Gulf of Palermo, Italy)

2009

Abstract The Gulf of Palermo (Italy, Mediterranean Sea) is a contaminated coastal environment with a relatively high influx of unregulated industrial and domestic effluents. Two sediment box-cores were collected at water depths of 100 and 712 m. Samples were analysed for trace metals (As, Cu, Hg, Mn, Ni, Pb), total polycyclic aromatic hydrocarbons (ΣPAHs), organic carbon to total nitrogen (Corg/Ntot) ratios and organic carbon and nitrogen isotopic composition (δ13Corg and δ15Ntot). At the coastal site, trace metal and ΣPAH depth profiles show a clear upcore increase, indicating increasing contamination over the recent past. Concentrations of ΣPAHs, Hg, Pb, Cu, and As appear to be potentiall…

Alexis de Tocqueville e l'inquietudine democratica

2020

Il mio contributo intende mostrare come la "nuova scienza della politica" , esposta nella Democrazia in America, offra un impianto categoriale ancora oggi assai utile nell'analisi della genesi e dello sviluppo della "democrazia" moderna, anto nei suoi aspetti positivi quanto nei suoi possibili sviluppi patologici.

Fra libertà e democrazia. L'eredità di Tocqueville e J. S. Mill, a cura di D. Bolognesi e S.Mattarelli.

2009

Il volume tratta dell'analisi del rapporto tra libertà e democrazia alla luce delle teorie elaborate da Tocqueville e da Mill.

Chloroplast signal length requirement reflects the outer membrane and TOC complex dimension

2015

Background and Purpose: The evolution of an efficient preprotein targeting and translocation system was a central prerequisite for the endosymbiotic integration of a -proteobacteria and cyanobacteria as cellular organelles. Today, it is widely accepted that during evolution most (pre-)proteins destined for these two organelles were equipped with an N-terminal targeting signal for localization. While multiple modes of evolution of these extensions are currently discussed, all evolved signals serve the same function – forming a signal for targeting to the correct organelle and translocation across both membranes. We aimed to generalize the current idea for the length requirement of the N-term…

Cenomanian–Turonian carbonate and organic-carbon isotope records, biostratigraphy and provenance of a key section in NE Sicily, Italy: Palaeoceanogra…

2008

In eastern Sicily, a series of highly organic-rich black shales occur as exotic blocks (~ 100 m across) floating in tectonized sediments (Argille Varicolori Unit containing olistoliths of Cretaceous-Palaeogene age). A 19-metre section, through one of these blocks near the town of Novara di Sicilia, includes cyclically bedded black shales, marlstones and claystones, which have been dated using planktonic foraminiferal and nannofossil biostratigraphy. On this basis, the section is assigned to the latest Cenomanian and clearly represents a manifestation of the Oceanic Anoxic Event characteristic of that interval. Total organic-carbon values range up to 23% and the relatively high hydrogen indi…

In Vitro Antioxidant Activity and In Vivo Topical Efficacy of Lipid Nanoparticles Co-Loading Idebenone and Tocopheryl Acetate

2019

Idebenone (IDE) is a strong antioxidant that has been proposed for the treatment of skin disorders, including skin ageing. Unfavorable physico-chemical properties make IDE a poor skin permeant where effectiveness could be improved by its loading into suitable delivery systems such as solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC). In this work, we designed novel IDE-loaded NLC containing tocopheryl acetate (VitE) as a liquid component to obtain a synergic effect between IDE and VitE. The resulting NLC showed small particle sizes (24&ndash

ChemInform Abstract: Exploring the Anticancer Potential of Pyrazolo[1,2-a]benzo[1,2,3,4]tetrazin-3-one Derivatives: The Effect on Apoptosis Induction…

2013

Abstract In order to investigate their anticancer potential, four new pyrazolo[1,2-a]benzo[1,2,3,4]tetrazinone derivatives, designed through the chemometric protocol VLAK, and three of the most active compounds of the previous series have been evaluated on some cellular events including proliferation, apoptosis induction, and cell cycle. The NCI one dose (10 μM) screening revealed that the 8,9-di-methyl derivative showed activity against Leukemia (CCRF-CEM) and Colon cancer cell line (COLO 205), reaching 81% and 45% of growth inhibition (GI), respectively. Replacement of the two methyl groups with two chlorine atoms maintained the activity toward Leukemia cell (CCRF-CEM, GI 77%) and selecti…
