Gioacchino Ventura e Napoleone III: la résurrection de l’Empire comme celle du jour de Pâques
2019
Starting from the observation of Luigi Sturzo who interpreted Gioacchino Ventura’s French period as a phase of involution of his political thought, this essay examines Ventura’s reflections on the 2 December coup d’état. In order to understand the reasons that pushed the Sicilian Theatine to exalt, after the enthusiastic adherence to the ideals of ‘48, the Second Empire as a consecration of a divine plan aimed to preserving the sovereignty, to support the Church, and to reject the advance of a democracy opened to socialist demands, the analysis will focus on the political judgments expressed in the preaches of 1857 held in the imperial chapel of the Tuileries.
Differential expression and glycosylation of proteins in the rat ileal epithelium in response to Echinostoma caproni infection.
2013
Echinostoma caproni (Trematoda: Echinostomatidae) is an intestinal trematode that has been used as experimental model to investigate the factors determining the expulsion of intestinal helminths. We analyze the changes in the protein expression and glycosylation induced by E. caproni in Wistar rat, a host of low compatibility in which the parasites are rapidly rejected. To determine the changes in protein expression, two-dimensional difference gel electrophoresis was employed using protein extracts from the intestine of naïve and infected rats. The patterns of glycosylation were analyzed by lectin blotting. Those spots showing differential expression or glycosylation were analyzed by mass s…
Cytotoxic capability and the associated proteomic profile of cell-free coelomic fluid extracts from the edible sea cucumber Holothuria tubulosa on He…
2022
Hepatocellular carcinoma (HCC) is an aggressive cancer histotype and one of the most common types of cancer worldwide. The identification of compounds that might intervene to restrain neoplastic cell growth appears imperative due to its elevated overall mortality. The marine environment represents a reservoir rich in bioactive compounds in terms of primary and secondary metabolites produced by aquatic animals, mainly invertebrates. In the present study, we determined whether the water-soluble cell-free extract of the coelomic fluid (CFE) of the edible sea cucumber Holothuria tubulosa could play an anti-HCC role in vitro by analyzing the viability and locomotory behavior, cell cycle distribu…
Herbicidal activity of essential oils extracted from different Mediterranean species against Echinochloa crus galli
Weed infestation in agricultural fields can cause huge economic losses and low-quality crop yields. Echinochloa crus-galli (L.) P.Beauv. (barnyardgrass) is one of the greatest yields limiting weeds in rice cultivation systems. It is a cosmopolitan weed in both temperate and tropical regions and is reported as a weed in 36 different crops in 61 countries. The success of this weed may be attributed to the production of large numbers of small, easily dispersed seeds per plant, possession of seed dormancy, rapid development and ability to flower under a wide range of photoperiods, and relative resistance of mature plants to herbicide sprays. Thus, the best way to control barnyardgrass in an env…
DIVERSIFICATION OF HIPPO SIGNALING COMPONENTS IN SELECTED METAZOAN SPECIES
La via di segnalazione intracellulare conosciuta come Hippo pathway svolge un ruolo chiave nei processi che regolano il controllo della dimensione degli organi, la proliferazione, l’apoptosi, il mantenimento delle caratteristiche di staminalità cellulare. Alterazioni nel pathway sono state descritte in molti tipi di tumori. Il nome deriva da una delle sue componenti principali, la proteina chinasi Hippo (Hpo), identificata per la prima volta in Drosophila melanogaster. Mutazioni nel gene Hpo inducevano la crescita abnorme di tessuti e organi. Componenti del pathway Hippo sono stati successivamente individuati anche nei mammiferi. Gli elementi fondamentali sono costituiti dalla proteine chin…
<p class="HeadingRunIn"><strong>Reinterpretation of the enigmatic Ordovician genus <em>Bolboporites </em>(Echinodermata)</…
2019
Bolboporites is an enigmatic Ordovician cone-shaped fossil, the precise nature and systematic affinities of which have been controversial over almost two centuries. For the first time, a wide range of techniques (CT-scan, SEM, cathodoluminescence, XPL, UV epifluorescence, EBSD, FT-IR and XRF spectrometry) were applied to well-preserved specimens of Bolboporites from Norway and Russia. Our main finding confirms its echinoderm affinities, as shown by its stereomic microstructure and by the first definitive evidence of its monocrystalline nature. Each cone consists in a single, microporous calcitic crystal with a narrow longitudinal internal canal. These results are combined with all previous …
Echinostomes in the definitive host: a model for the study of host-parasite relationships.
2008
Echinostomes are hermaphroditic digeneans that parasitize, as adults, numerous vertebrate hosts of all classes. In this chapter, the main features of the development of adult echinostome in the definitive host are analyzed in detail. The stage of the echinostome in the definitive host undergoes a number of features such as metacercarial excystment, establishment, habitat location, adult development, mate, and release of eggs. These features are documented with an emphasis in their potential use as experimental models. The analysis is focused on members of the genus Echinostoma, although members of other genera of the Echinostomatidae are mentioned when they are relevant to the discussion. A…

Attività antibatterica di peptidi estratti da celomociti di echinodermi
2010
Negli echinodermi la difesa dell’organismo dalle invasioni microbiche avviene tramite meccanismi cellulari e umorali dell’immunità innata. Una componente fondamentale dei fattori umorali è costituita dai peptidi antimicrobici (AMPs) molto conservati con un ampio spettro di attività antimicrobica contro batteri, virus e funghi. Solitamente gli AMPs sono costituiti da meno di 100 amminoacidi, sono cationici e formano strutture anfipatiche. In questo lavoro dimostriamo che i celomociti dell’Echinoideo Paracentrotus lividus e dell’Oloturoideo Holothuria tubulosa contengono sostanze con attività antimicrobica verso diversi ceppi batterici patogeni umani. In entrambe le specie, nel precipitato ac…
Specific tyrosine phosphorylation in response to bile in Fasciola hepatica and Echinostoma friedi
2003
Protein tyrosine phosphorylation (PY) is a well-known signalling mechanism which is also involved in host-parasite interactions. Despite its transcendence, PY has been poorly studied in parasitic helminths. The aim of this study is to examine the effect of bile salts on the PY pattern in parasitic trematodes. Two distinct adult models were analysed: Echinostoma friedi, of intestinal habitat, and Fasciola hepatica, naturally inhabitant of host biliary channels. Our results show that bile salts induce specific and distinct protein PY in both trematode species, indicating that this signalling process seems to be also involved in host-trematode relationships.
