Temperature and pressure dependence of quercetin-3-O-palmitate interaction with a model phospholipid membrane: film balance and scanning probe micros…

2004

The molecular interaction of quercetin-3-O-palmitate (QP) with dimyristoylphosphatidylcholine (DMPC) has been studied. Film balance measurements of the average molecular area vs QP molar fraction in DMPC/QP mixed monolayers showed that relevant positive deviations from ideality, i.e., a less dense monolayer packing, occurred for a temperature of 10 degrees C, below the critical melting transition temperature of DMPC monolayers T c m approximately equal 20 degrees C), while ideal behavior was observed at 37 degrees C, above this phase transition temperature. The positive deviation observed at low temperatures in the average molecular area increased with the surface pressure. Scanning probe m…

Scrittura come vendetta. Gli Inferni di Anton Francesco Doni fra realismo allegorico e sintassi manierista

2022

Esito della contaminazione del modello dantesco con innumerevoli altre fonti - dalla letteratura odeporica a quella utopica, dalla prosa religiosa alla poesia burlesca – gli Inferni (1553) di Anton Francesco Doni rappresentano un’opera irriducibile ad un genere predefinito, aperta al gioco intertestuale e all’interazione fra testo e immagini. In una prosa eccentrica e originale, frutto della sua sensibilità manieristica, lo scrittore cinquecentesco ci consegna infatti una potente allegoria della condizione umana, uno specchio rovesciato del mondo come la luna ariostesca, brandendo la penna come una spada per smascherare – tra moralità e ironia – le menzogne della società del tempo.

I CASTELLI DELLE RIVOLTE. DALLA PIANA DI PARTINICO ALLA VALLE DELLO JATO (PALERMO) SULLE TRACCE DEGLI ULTIMI MUSULMANI IN SICILIA OCCIDENTALE

2017

Following the excavations of the "Castellazzo" fortress of Jato, it became necessary to revise the archaeological materials coming from excavation and reconnaissance in all those fortified sites that welcomed the Muslim population during the revolts between the last Norman and Swabian ages. Attention was thus focused on at least two phases in the construction of such fortresses, often simple towers rather than real castles, corresponding to the beginning of the Norman domination and the Federician period.

Morphological and genetic variation of Chamaerops humilis (Arecaceae) in relation to the altitude

2021

The Mediterranean dwarf palm (Chamaerops humilis L.) is native to Western and Central Mediterranean. Since classical times this species has been cultivated and several varieties have been described on material of unknown origins. In this study, plants grown from seeds collected in the wild from seven populations spread along the Mediterranean basin were cultivated under the same environmental conditions, investigated morphologically and genetically by screening the polymorphism of ten SSR loci. Two groups are clearly separated, the populations growing at low altitudes and those living above a thousand meters of altitude. Due to morphological, geographic and environmental isolation, here it …

Fine Structure of Antennal Sensilla of Paysandisia archon and Electrophysiological Responses to Volatile Compounds Associated with Host Palms

2014

Paysandisia archon (Lepidoptera: Castniidae) is a serious pest of palm trees. A comprehensive knowledge of the insect olfactory system is essential for the development of efficient semiochemical-based control methods. The olfactory sensilla are located particularly on the antennae, and these can detect plant volatiles that provide important cues for the insects in the search for their host plants. To date, the fine structure of P. archon antennal sensilla studies and their role in host-plant perception have not been investigated in great detail. Using light microscopy and scanning and transmission electron microscopy, the antennae of both sexes of P. archon are described here in detail, acc…

Papillon- Lefevre Syndrome: Report of a case and its management

2012

Papillon-Lefèvre Syndrome (PLS) is a rare autosomal recessive disorder first described by two French physicians, Papillon and Lefèvre in 1924. The disorder is characterized by diffuse palmoplantar keratoderma and precocious aggressively progressing periodontitis, leading to the premature loss of deciduous and permanent teeth at a very young age. The cutaneous lesions are usually manifested simultaneously with the intra-oral presentations and include keratotic plaques on the palms and soles varying from mild psoriasiform scaly skin to overt hyperkeratosis. The etiopathogenesis of the syndrome is relatively obscure and immunologic, genetic or possible bacterial etiologies have been proposed. …

Phylogeographic analysis of the red seaweed Palmaria palmata reveals a Pleistocene marine glacial refugium in the English Channel

2005

Phylogeography has provided a new approach to the analysis of the postglacial history of a wide range of taxa but, to date, little is known about the effect of glacial periods on the marine biota of Europe. We have utilized a combination of nuclear, plastid and mitochondrial genetic markers to study the biogeographic history of the red seaweed Palmaria palmata in the North Atlantic. Analysis of the nuclear rDNA operon (ITS1-5.8S-ITS2), the plastid 16S-trnI-trnA-23S-5S, rbcL-rbcS and rpl12-rps31-rpl9 regions and the mitochondrial cox2-3 spacer has revealed the existence of a previously unidentified marine refugium in the English Channel, along with possible secondary refugia off the southwes…

Phytophthora Root and Collar Rot of Paulownia, a New Disease for Europe

2021

Paulownia species are fast growing trees native to China, which are being grown in managed plantings in several European countries for the production of wood and biomasses. In 2018, wilting, stunting, leaf yellowing, and collapse, as a consequence of root and crown rot, were observed in around 40% of trees of a 2-year-old planting of Paulownia elongata × P. fortunei in Calabria (Southern Italy). Two species of Phytophthora were consistently recovered from roots, basal stem bark, and rhizosphere soil of symptomatic trees and were identified as Ph. nicotianae and Ph. palmivora on the basis of both morphological characteristics and phylogenetic analysis of rDNA ITS sequences. Koch’s postulates…

Application of algae in active biomonitoring of the selected holding reservoirs in swietokrzyskie province

2016

Abstract During the years 2014-2015, biomonitoring studies were carried out at three holding reservoirs located in Swietokrzyskie Province (central Poland): Kielce artificial lake, Chancza reservoir and Sielpia reservoir. In sea water algae Palmaria palmata (Linnaeus) Weber & Mohr, exposed in the analysed waters, the increases of concentrations were determined by the atomic absorption spectrometry method (AAS), of the following: Mn, Fe, Cu, Zn, Cd and Pb. Conductivity and pH were also determined in the reservoirs waters. The differences between the increases of heavy metal concentrations in the samples of algae found along the coastline were indicated; they result from different distanc…
