Otra visión de la historia del mueble. La evolución técnica, base de la formal

2008

La evolución del mobiliario no sólo está condicionada por la transformación en los estilos de vida, sino también por el desarrollo de técnicas de elaboración de la madera. Este artículo está dirigido a aquellos que investigan o se aproximan al mobiliario y las artes decorativas, con la intención de proporcionar una herramienta para la comprensión de la evolución constructiva y de las técnicas decorativas.

TAVI imaging: over the echocardiography

2020

Aortic valve stenosis (AS) is a common valvular heart disease. Recently, transcatheter aortic valve implantation (TAVI) has changed the treatment of severe AS in elderly patients with contraindications to traditional surgical replacement. Echocardiography is conventionally used as the first imaging modality to assess the presence and severity of AS and to provide anatomical and functional information. Nowadays, imaging techniques play a crucial role in the planning of TAVI to define suitable candidates. Computed tomography (CT) is essential to display the anatomy of the aortic valve complex (including aortic annulus, Valsalva sinuses, coronary arteries ostia, sinotubular junction), thoracoa…

Valvular Heart Disease

2013

Valvular heart disease (VHD) refers to a wide spectrum of cardiac disorders that affect a large number of patients. Echocardiography is still considered the pivotal imaging method to evaluate the cardiac valves. However, echocardiography has some intrinsic limitations due to operator dependence and patient habitus. In the last two decades three-dimensional techniques such as magnetic resonance imaging (MRI) and computed tomography (CT) have provided valuable assessment of VHD. MRI overcomes the limitation of the poor acoustic window of echocardiography without ionizing radiation. Nowadays, MRI aims to be considered as the reference standard for imaging cardiac valves because of the improved…

A study on the essential oil Ferulago campestris. How much does exstraction method influence the oil composition?

2010

The essential oil of different parts of Ferulago campestris (Bess.) collected in Sicily has been extracted by microwave-assisted hydrodistillation (MAHD) and by classic hydrodistillation (HD). A comparative qualitative- quantitative study on the composition of the oils was carried out. A total of 100 compounds were identified in the oils obtained by MAHD, whereas 88 compounds characterized the HD oils. The most prominent components were, in all different parts of F. campestris and in both extraction methods, 2,4,5- trimethylbenzaldehyde and 2,4,6-trimethylbenzaldehyde isomers; the latter was not previously found. The attempt to evaluate where the oil components are located in all parts of t…

Note citotassonomiche sul genere Thapsia L. (Apiaceae)

2008

This study aims to clarify the taxonomic states and relations within the genus Thapsia from the Mediterranean area, with particular interest to the populations growing in Sicily. The results of morphological and karyological investigations on living plants, combined with herbarium surveys and literature data, allowed us to define an updated taxonomic profile of the genus Thapsia, with the description of a new species from the island of Lampedusa (SW Sicily), named T. pelagica. Moreover a new taxonomic combination is proposed for the populations of Peloritani Mts. (NE Sicily), which are here treated as subspecies messanensis of T. garganica.

Morphological, karyological and taxonomic remarks on Ferulago nodosa (L.) Boiss. (Apiaceae)

2012

Abstract Western (Sicilian) and eastern (Balcan-aegean) populations of the Balcan-tyrrhenian Ferulago nodosa are reported to be different in some morphological characters, and were considered different species by some authors in XIX century. In this work, fruit and pollen morphologies have been compared in Sicilian and Cretan plants; also, the chromosome number of Sicilian plants has been ascertained. Preliminary results highlight a general homogeneity between the two populations, nevertheless showing significant differences in some parameters (fruit form, pollen size). For this reason, and considering the geographic disjunction of the Sicilian plants, the two populations are proposed to be…

First report of brown rot and wilt of fennel caused by Phytophthora megasperma in Italy

2019

Fennel (Foeniculum vulgare Mill. var. azoricum (Mill.) Thell.) in the Apiaceae family is native to southern Europe and southwestern Asia. It is an economically important crop in Italy that produces approximately 85% of all fennel worldwide. The main producing regions are Apulia, Campania, Latium, and Calabria. During the late winter of 2004 in the Crotone Province of the Calabria Region, following heavy rains, patches of fennel plants with symptoms of brown, soft rot of the bulb-like structure formed by the thickened leaf bases, development of yellow leaves, stunting, and wilting of the entire plant were observed in fields. A homothallic Phytophthora sp. was isolated consistently from the …
