Foreed flushing of branch segments as a method for obtaining reactive explants of mature Quercus robur trees for micropropagation
1994
The aim of this study was to micropropagate mature Quercus robur L. trees when material retaining physiologically juvenile characteristics (stump sprouts, epicormic shoots) is not available. Branch segments from 70–300 year-old trees were force-flushed and the flushed, partially rejuvenated or reinvigorated shoots were used as a source of explants for establishment of cultures. In vitro establishment and multiplication was achieved with seven of the eight selected trees. The proliferation capacity of cultures of vertically placed explants declined after several subcultures, but efficient shoot multiplication was achieved by culturing decapitated shoots placed horizontally on GD medium suppl…

IFN-gamma-induced protein 10 is a novel biomarker of rhinovirus-induced asthma exacerbations
2007
BACKGROUND: Rhinovirus-induced acute asthma is the most frequent trigger for asthma exacerbations. OBJECTIVE: We assessed which inflammatory mediators were released from bronchial epithelial cells (BECs) after infection with rhinovirus and then determined whether they were also present in subjects with acute virus-induced asthma, with the aim to identify a biomarker or biomarkers for acute virus-induced asthma. METHODS: BECs were obtained from bronchial brushings of steroid-naive asthmatic subjects and healthy nonatopic control subjects. Cells were infected with rhinovirus 16. Inflammatory mediators were measured by means of flow cytometry with a cytometric bead array. Subjects with acute a…
Heliodorus Parthenopaeus: The "Aithiopika" in Baroque Naples
1998
L'articolo è frutto di un lavoro comune; i paragrafi 1, 3 e 6 sono stati redatti da Massimo Fusillo, i paragrafi 2, 4 e 5 da Clotilde Bertoni. Il lavoro analizza il "Teagene", poema epico di Giambattista Basile ispirato alle "Etiopiche" di Eliodoro, e prende in esame altre opere seicentesche legate al romanzo ellenistico. The article results from a common work: paragraphs 1, 3 and 6 have been written by Massimo Fusillo, paragraphs 2, 4 and 5 by Clotilde Bertoni. It analyzes "Teagene" an epic poem by Giambattista Basile, based on Heliodorus' Aethiopica, and it also examines some other works of the same period connected with th Hellenistic novel.
Evaluation of apical preparations performed with ultrasonic diamond and stainless steel tips at different intensities using a scanning electron micro…
2011
Objective: The objective of our study is to analyse (with the help of scanning electron microscopes) the quality of the dental root surface and the appearance of dental cracks after performing apical preparations using two diffe-rent types of ultrasonic tips. Study design: We used 32 single-rooted teeth that underwent a root canal and apical resection. Afterwards, the teeth were divided into 4 groups of 8 teeth each, with preparations of the apical cavities in the following manner: Group 1: stainless steel ultrasonic tip at 33KHz. Group 2: stainless steel ultrasonic tip at 30KHz. Group 3: diamond ultrasonic tip at 30KHz. Group 4: diamond ultrasonic tip at 33 KHz. The quality of the root sur…
Effects of prison work programmes on the employability of ex-prisoners
2014
This paper presents the results of a study that links information from the prison system with information from the Spanish Social Security System in order to study the employability of former inmates of prisons in Catalonia, Spain. Few studies of this type have been carried out in the world and this is the first in Spain. The results show that 43.6 percent of ex-prisoners find a job after serving their sentence, but their integration in the labour market tends to be fragile, confirming that it is a very vulnerable group. It was also found that prison work has a favourable effect on employability and that vocational training has a lesser or no effect. Fil: Alós, Ramon. Universitat Autònoma d…
Studio geobotanico del Parco Eolico di Ulassai
2008
Il Parco Eolico di Ulassai sembra la materializzazione di un ossimoro: gli imponenti aerogeneratori, quasi avessero compiuto un viaggio a ritroso nel tempo, sorprendono l’osservatore in un paesaggio antico, modellato da una gestione del territorio rimasta pressoché invariata da millenni. Nello spazio tra la torre eolica 43 e i resti del Nuraghe Cea Arcis, poco discosto, è riassunta la storia di un luogo sardo recondito ma significativo. Tra gli aerogeneratori disseminati sulle dolci ondulazioni del Parco Eolico, si aggirano indolenti gli animali al pascolo: mucche, pecore, capre, maiali. Tutt’attorno, l’orizzonte è segnato dai profili scultorei e primordiali dei tacchi d’Ogliastra. E quei 2…
IRSp53 controls plasma membrane shape and polarized transport at the nascent lumen in epithelial tubules.
2020
It is unclear whether the establishment of apical–basal cell polarity during the generation of epithelial lumens requires molecules acting at the plasma membrane/actin interface. Here, we show that the I-BAR-containing IRSp53 protein controls lumen formation and the positioning of the polarity determinants aPKC and podocalyxin. Molecularly, IRSp53 acts by regulating the localization and activity of the small GTPase RAB35, and by interacting with the actin capping protein EPS8. Using correlative light and electron microscopy, we further show that IRSp53 ensures the shape and continuity of the opposing plasma membrane of two daughter cells, leading to the formation of a single apical lumen.
