Biodiversity of Indigenous Saccharomyces Populations from Old Wineries of South-Eastern Sicily (Italy): Preservation and Economic Potential
In recent years, the preservation of biodiversity has become an important issue. Despite much public discussion, however, current practices in the food industry seldom take account of its potential economic importance: on the contrary, the introduction of industrialized agriculture practices over large areas has often resulted in a dramatic reduction in biodiversity
Characterization of Lipopeptides Produced by Bacillus licheniformis using Liquid Chromatography with Accurate Tandem Mass Spectrometry
The plant endophyte Bacillus licheniformis, isolated from leaves of Vitis vinifera, was studied to individuate and characterize the presence of bioactive lipopeptides having aminoacidic structures

Prognostic factors in neuroendocrine tumours of the lung: a single-centre experience
Abstract
OBJECTIVES:
To assess the independent prognostic role of histological subtypes, tumour size and lymph nodal involvement upon survival in lung neuroendocrine tumours (NETs).
METHODS:
A retrospective search of the database of the Department of Thoracic Surgery (Turin, Italy) identified 157 patients operated on for a newly diagnosed NET between January 1995 and December 2011. Multivariable Cox models were used to analyse predictors of overall survival and progression-free survival.
RESULTS:
According to histology, 71 (45.2%) were typical carcinoids (TCs), 35 (22.3%) atypical carcinoids (ACs), 37 (23.6%) large-cell neuroendocrine carcinomas (LCNCs) and 14 (8.9%) small-cell lung carcinomas (SCLCs). After a median follow-up time of 6.5 years, 60 patients died and 73 had a recurrence or died. The overall 5-, 10- and 15-year survival rates were 64%, 53% and 46%, respectively. Older age, histology (ACs, LCNCs and SCLCs vs TCs) and lymph nodal involvement were confirmed to be independent negative prognostic factors in the multivariable models for overall survival and progression-free survival.
CONCLUSIONS:
Tumour histology and lymph nodal involvement are definitively the predominant and relevant factors influencing survival. ACs showed an intermediate prognosis between TCs and poorly differentiated NETs
Mt-DNA RFLP patterns obtained at the end of fermentation from Nero d'Avola (lane 3) and Frappato (lane 4), inoculated with B2–48 (A), B2–25 (B), ICV-D254 (C) and QD-145 (D).
<p>Control RFLP patterns obtained with DNA from the pure cultures of each isolate are shown in lane 2 of each panel. Lane 1, molecular marker (1 kb ladder, BDH).</p
Mt-DNA RFLP patterns of 14 isolates (indicated) used for the 100 liter fermentations of 2004.
<p>A. Patterns obtained with the <i>RsaI</i> enzyme. B. patterns obtained with the <i>HinfI</i> enzyme. M, molecular marker (1 kb ladder, BHD).</p
