BACKGROUND Recent advances in technology have provided the opportunity for off-line analysis of digital video-clips of two-dimensional (2-D) echocardiographic images. Commercially available software that follows the motion of cardiac structures during cardiac cycle computes both regional and global velocity, strain, and strain rate (SR). The present study(More)
The genetic homogeneity of the people of Sardinia makes it an ideal place to study genetic related diseases such as type 1 diabetes, which in this island has one of the highest incidence worldwide. The principal objective of this study was to use 1H high-resolution NMR spectroscopy and supervised methods of multivariate data analysis to highlight the(More)
MOTIVATION The analysis of high-resolution proton nuclear magnetic resonance (NMR) spectrometry can assist human experts to implicate metabolites expressed by diseased biofluids. Here, we explore an intermediate representation, between spectral trace and classifier, able to furnish a communicative interface between expert and machine. This representation(More)
In order to elucidate the metabolite changes associated with hepatocellular carcinoma (HCC) oncogenesis and progression, we compared the profiles obtained by 1D proton HRMAS NMR spectroscopy of 51 needle biopsies (14 primary nodules, 14 recurrent, and 23 paired cirrhotic specimens). The diagnosis of HCC was based on 2 concordant imaging techniques and was(More)
