Improving accuracy of the intermediate splint in substantial intermaxillary sagittal discrepancies using an extra anterior anchorage point: technical…

2021

Background To describe a technical feature that increases the stability of the intermediate splint in patients where bimaxillary surgery with great maxillary/mandibular advancements are planned. Material and Methods Prospective evaluation of the intermediate splint dental vertical penetration in patients undergoing bimaxillary surgery where great sagittal discrepancy occur in the anterior sector between the upper and lower jaws when the intermediate splint is placed by adding an extra intermaxillary fixation (IMF) screw (2x9 mm) placed between the central incisors of the maxilla and fixed to the most anterior aspect of the intermediate splint following the direction of the sagittal maxillo-…

Imaging of Gastrointestinal Stromal Tumors: From Diagnosis to Evaluation of Therapeutic Response

2016

Once considered an obscure tumor entity with poor prognosis, gastrointestinal stromal tumors (GISTs) are nowadays recognized as the most common mesenchymal tumors of the alimentary tract. GISTs differ from other mesenchymal neoplasms at pathology since 90% of them exhibit strong immunohistochemical staining for KIT, a tyrosinase kinase growth factor receptor. In the early 2000s, the ability of imatinib mesylate, a tyrosine kinase inhibitor, to inhibit KIT established a new paradigm for cancer treatment. A reduction in lesion size may not be observed or may appear many months after therapy; thus, tumor response criteria alternative to the Response Evaluation Criteria in Solid Tumors were dev…

Semi-automatic quantitative RT-PCR to measure CYP induction by drugs in human hepatocytes

2003

An assay has been developed for the quantitative measurement of CYP mRNA content of the major human isoforms (1A1, 1A2, 2A6, 2B6, 2C9, 2C19, 2D6, 2E1, 3A4 and 3A5) in human hepatocytes. The method is based on the conversion of mRNAs into their corresponding cDNAs, followed by PCR amplification using appropriate primers. Making use of appropriate internal and external standards it is possible to estimate changes in CYP mRNA content of hepatocytes. The technique has been standardised to run semi-automatically. This procedure can be used to assess the CYP induction potential of new pharmaceuticals at a pre-clinical stage of development. To this aim, human hepatocytes obtained from functional l…

SOLUZIONI OPERATIVE ED ASPETTI QUALITATIVI PER LA GEOCODIFICA DI POPOLAZIONI IN AMBITO SANITARIO.

2015

IntroduzioneL'utilizzo dei Geographic Information Systems (GIS) in ambito sanitario, continua a ricevere grande attenzione. La disponibilità di informazioni sulla localizzazione degli individui, consente di effettuare associazioni territoriali sulle cause delle patologie, nonché di indagare aspetti legati alla distribuzione dei servizi sanitari ed all'equità di accesso alle cure. ObiettiviAnalizzare le principali problematiche e le soluzioni operative per la geocodifica di popolazioni e proporre un indice di qualità della geocodifica di cui poter tenere conto in sede di analisi. MetodiCome caso studio vengono illustrate le fasi che hanno portato alla georeferenziazione di indirizzi residenz…

Geobotanical approach to detect land-use change of a Mediterranean landscape: a case study in Central-Western Sicily

2018

A landscape is a palimpsest of the interactions between human activities and ecological dynamics. In an interdisciplinary perspective of dialogue between the ‘Two Cultures’ (Natural Sciences and Humanities), a study of a rural area has been carried out through a reading of plant ecosystems as signs of human impact. The purpose of this paper—as part of the project ‘Harvesting Memories’: Ecology and landscape archaeology of Castro/Giardinallo Valley and Mt. Barrau district (Corleone, Palermo, Sicily)—is to analyse the formative-processes of a Sicilian rural landscape and its changes in the last century. A key element in the reconstruction of the formation of the present landscape is the serie…

Effects of training and assessment in vocational education and training (VET): Reflections on the methodology of assessing the development of traits …

2006

Abstract This article focuses on the development of traits of self-regulation within vocational education and training (VET). This perspective is in accordance with the general objective of VET within the German speaking countries and is addressed in the objective “education and training for the ability of self-directed planning, regulation and evaluation of vocational performance”. In order to foster these and other relevant abilities, specific vocational training programs were developed and implemented in a training center in Switzerland. One such program was evaluated in a longitudinal study. From 1999 to 2003, a cohort of more than 100 aprentices was monitored with respect to the develo…

A study of thyme germplasm in Sicily

2009

hyme is characteristic of the Mediterranean and is of interest for its multifunctional nature. It is widely used in seasoning and flavouring, in herbal products and cosmetics. The versatility of this species means it is also useful in the protection of areas prone to erosion or an ornamental plant when designing low-maintenance gardens. Thyme germplasm constitutes a large part of the wild flora in Sicily and is a potentially useful source of genetic variability. On the basis of this, in the two-year period from 2004-2005, research was carried out on wild thyme accessions. These were used to evaluate both its productivity and individual biotypes with the functional characteristics most sough…

TWO YEARS OF STUDIES INTO NATIVE BERMUDAGRASS (CYNODON SPP.) GERMPLASM FROM SICILY (ITALY) FOR THE CONSTITUTION OF TURF CULTIVARS

2008

Bermudagrass (Cynodon spp.) is the most widely used warm season turf species in the world for sport, lawn and utility turfs. The species is widespread in Sicily (Italy) where it exhibits a large range of diverse morphological characteristics due to a long process of adaptation to varying climatic and soil conditions of the island. In order to exploit the bermudagrass genetic resources and establish a germplasm bank for use in various plant breeding programmes, bio-agronomic evaluation tests were carried out on the 40 Sicilian biotypes of Cynodon spp. from 2002 to 2004 at the experimental farm “Orleans”, University of Palermo. The accessions were compared to the standard cultivar ‘Savannah’,…
