Free radical scavenging abilities of flavonoids as mechanism of protection against mutagenicity induced by tert-butyl hydroperoxide or cumene hydrope…

2003

Mutagenicity induced by tert-butyl hydroperoxide (BHP) or cumene hydroperoxide (CHP) in Salmonella typhimurium TA102 was effectively reduced by flavonols with 3',4'-hydroxyl groups such as fisetin, quercetin, rutin, isoquercitrin, hyperoxide, myricetin, myricitrin, robinetin, and to a lesser extent also by morin and kaempferol (ID50=0.25-1.05 micromol per plate). With the exception of isorhamnetin, rhamnetin, morin, and kaempferol, closely similar results were obtained with both peroxides. Hydrogenation of the double bond between carbons 2 and 3 (dihydroquercetin, dihydrorobinetin) as well as the additional elimination of the carbonyl function at carbon 4 (catechins) resulted in a loss of a…

L’archéologue classique aux prises avec le monde diplomatique. Le cas de Salomon Reinach en 1881

2017

Classical Archeology Clashing with the World of Diplomacy: the Case of Salomon Reinach in 1881 Studies on the ties between archeology and diplomacy focus mostly on the way a few individuals reconciled a double career and realized the ideal of a hybrid figure: the diplomat as archeologist. Less attention has been paid to the relations, on a daily basis, between classical archeology and the world of consulates and embassies in the Eastern Mediterranean. Most of the time, one relies on the widespread cliché of the archeologist as a victim of bureaucracy. The case studied here is that of Salomon Reinach (1858-1932) and his abundant correspondence, held by the bibliothèque Méjanes (Aix-en-Proven…

The biological control applied in Citrus orchards against harmful exotic pests in Sicily (Italy)

2018

The citrus groves are injured by infestations caused by indigenous species or old and new phytophagous introduced. Several problems have found in the biological control a optimal solution that allowed a considerable reduction in the use of chemical products. In fact, applications of programs using biological methods has been more successful on citrus than in any other cropping system. Sicily (Italy), due to its location in the Mediterranean Sea, represents an island particularly rich flora and fauna with a characteristic biodiversity different from those of other countries and regions of Italy. It produces about 60% of the national citrus production with more areas of organic citrus groves.…

Squaring Nemesis: Alexander’s Dream, the Oracle, and the Foundation of the New Smyrna

2022

In the 7th book of the Periegesis, Pausanias devotes a long digression to the Ionian migration in Asia Minor, focusing briefly on the story of Smyrna, whose territory originally belonged to the Aeolian settlers and was then occupied, at the beginning of the 7th century, by the Ionians from nearby Colophon. The arrival of Alexander the Great in the region marked the beginning of a new phase for Smyrna. Pausanias reports that the Macedonian king, on his way back from a hunting expedition on Mount Pagos, arrived at the sanctuary of the Nemeseis. There, the divinities appeared to him in a dream telling him to find a city and to bring there the inhabitants of the older polis. The Smyrnaeans then…

Fat plug myringoplasty: Analysis of a safe procedure for small tympanic perforations

2015

Objective: Assessment of value of fat plug myringoplasty as office-based procedure in small tympanic membrane perforations. Material and Methods: Prospective study of consecutive patients undergoing fat plug myringoplasty under local anesthesia. Minimum follow-up considered was 6 months, which included several microscopic examinations. All data were recorded and analyzed statistically. Results: 33 patients matched the inclusion criteria; the mean perforation size was 2.8 mm. No change in PTA was noted after surgery in the whole series. Recurrence of perforation was detected in 7 cases (21%), which was statistically related with the cause of perforation rather than location or size (p-value …

FOLLOW-UP AFTER PEDIATRIC MYRINGOPLASTY: OUTCOME AT 5 YEARS

2014

Aim. The aim of this paper was to evaluate anatomical and functional outcomes 5 years after myringoplasty in children affected by perforated eardrum. To analyze the main differences in the frequency of postoperative complications between patients under and over 9 years of age. Methods. One hundred and thirty-two children, aged from 4 to 15 years, who underwent myringoplasty with or without mastoidectomy, were followed for a five-year period after surgery. The cohort was divided in two groups: children from 4 to 9 years old (G1) and patients older than 9 years (G2); all subjects underwent a pre- and post-operatively clinical exam and were evaluated through audiometry and impedenzometry. Aden…

Diplopod hemocyanin sequence and the phylogenetic position of the Myriapoda

2001

Hemocyanins are copper-containing respiratory proteins of the Arthropoda that have so far been thoroughly investigated only in the Chelicerata and the Crustacea but have remained unstudied until now in the Myriapoda. Here we report the first sequence of a myriapod hemocyanin. The hemocyanin of Spirostreptus sp. (Diplopoda: Spirostreptidae) is composed of two distinct subunits that are arranged in a 6 x 6 native molecule. The cloned hemocyanin subunit cDNA codes of for a polypeptide of 653 amino acids (75.5 kDa) that includes a signal peptide of 18 amino acids. The sequence closely resembles that of the chelicerate hemocyanins. Molecular phylogenetic analyses reject with high statistical con…

A new species of Smyrnium (Apiaceae) related to S. perfoliatum

2015

On the basis of plant collections recently carried out in Sicily as well as the study of the herbarium material kept in PAL and PAL-Gr, a new species of Smyrnium (Apiaceae) is described here. This new taxon, named Smyrnium dimartinoi, is related to S. perfoliatum and is presently known from Sicily, Crete and realistically elsewhere in the Mediterranean. In such range it occurs in open woods and clearings of the Mediterranean-temperate and submontane belt.

Mononuclear rearrangement of heterocycles in zwitterionic micelles of amine oxide surfactants.

2012

Abstract Rate constants for the mononuclear rearrangement (MRH) of Z -phenylhydrazones of some 5-substituted-3-benzoyl-1,2,4-oxadiazoles in water have been measured in the presence of zwitterionic micelles. The use of micellized N -tetradecyl- N , N -dimethylamineoxide (C 14 DMAO) as the reaction medium allowed to solubilize the otherwise water-insoluble oxadiazoles. Micellar rate effects were analyzed by using a simple pseudo-phase model and compared with those obtained in non-ionic micelles (Triton X-100). Evidence that both the rate of the rearrangement reaction and the binding of the substrates to the micelles are mainly governed by substrate hydrophobicity is obtained. The disagreement…
