Un tesoretto dimenticato da Himera: Nuovi dati sul ripostiglio IGCH 2258
2022
Due to the troubled events that accompanied its discovery, the hoard IGCH 2258 has been neglected by scientific studies. The recent examination conducted at the Coin Cabinet of the Museum “A. Salinas "in Palermo, where the complex is kept, and the analysis of the archive documentation of the Museum and Central Archives of the State of Rome allowed to clarify the composition of the complex and to provide more precise information on the place of discovery, allowing to exploit the informative potential of this hoard.
La realtà museale a Palermo tra l’Ottocento e i primi decenni del Novecento
2009
Il contributo, connesso all'attività di Enrico Mauceri, oggetto del convegno, ripercorre alcune tra le principali tappe che hanno segnato la formazione, composizione e sviluppo del Museo Nazionale di Palermo. In sintesi sono individuati alcuni momenti molto importanti dal punto di vista museologico. Il primo si risolve nella figura di Antonino Salinas, per lungo tempo direttore, che è il vero artefice di un museo onnivoro e onnicomprensivo, volto alla rappresentazione di tutto quanto potesse rappresentare al meglio la Sicilia. Ciò comportò conseguentemente l'abbandono della velleitaria ambizione del precedente Museo dell'Università, primo nucleo dell'attuale, di porsi come museo di Belle Ar…
Phytochemical characterization and antioxidant activity of the aerial part extracts from two species of Matthiola wild in Sicily: Matthiola sinuata a…
2022
As part of a project aimed at investigating the specific and intraspecific taxa of Matthiola which grow spontaneously in Sicily (Italy), in this work our research has been focused on Matthiola tricuspidata and Matthiola sinuata. The phenolic and volatile compounds of the hydroalcoholic extracts from the aerial parts of the selected species have been characterized by HPLC-PDA/ESI-MS and SPME-GC/MS analyses. Moreover, the antioxidant capacity in vitro (1,1-diphenyl-2-picrylhydrazil (DPPH), reducing power and Fe2+ chelating activity assays) and the toxicity (Artemia salina lethality bioassay) of the extracts were investigated. The phytochemical analyses highlighted quite different phenolic and…
Phytochemical Profile and Antioxidant Activity of the Aerial Part Extracts from Matthiola incana subsp. rupestris and subsp . pulchella ( Brassicacea…
2021
As part of a project aimed at investigating the Matthiola taxa endemic to Sicily (Italy), this study focused on Matthiola incana, an edible species used in the traditional medicine of various countries. Herein, the characterization of phenolic and volatile compounds, the antioxidant capacity in vitro (1,1-diphenyl-2-picrylhydrazil (DPPH), reducing power and Fe2+ chelating activity assays) and the toxicity test (Artemia salina lethality bioassay) of the hydroalcoholic extracts from the aerial parts of M. incana subsp. rupestris from Mt. Pellegrino (Palermo) and Mt. Erice (Trapani), and of M. incana subsp. pulchella are reported. The results are compared with those previously shown for M. inc…

Determination of biological characteristics of Tunisian Artemia salina populations
2012
In this study, Artemia salina cysts collected from four Tunisian hypersaline environments were characterized using biometrical, biological and biochemical descriptors. Biometrical analysis revealed that the mean diameter value ranged from 220.25 to 237.76 μm, for the untreated cysts, from 199 to 224.52 μm for decapsulated cysts and that the chorion thickness ranged from 6.62 to 10.58 μm. 48 h after hatching, Artemia from Sebkha El Meleh, Sebha Moknine, Sfax saltworks and Sahline saltworks presented a hatching percentage of 52.7%, 53.75%, 70.16% and 43.74%, respectively. The length of the freshly hatched instar I nauplii varied from 429 to 449.34 μm. The fatty acids profile showed that the n…

Nutrients biochemistry in steppe saline lakes from “La Mancha Húmeda” Biosphere Reserve (Central Spain)
2023
La Mancha Húmeda Biosphere Reserve is one of the most important lakes districts in southern Europe. Shallow saline lakes are among the most representative ecosystems of this region. They experience different levels of cultural and natural eutrophication, in such way that most of them deserve urgent conservation and/or restoration actions. In this thesis, 17 representative lakes from the site were selected to study the seasonal patterns of nutrient dynamics (carbon, nitrogen and phosphorus) and its relationship with the ecological functioning. These lakes nearly represent the range of limnological conditions found in this Biosphere Reserve. A seasonal limnological survey was conducted, showi…
