    Coronary artery disease is the first cause of mortality in industrialized countries notwithstanding the diagnostic and therapeutic progresses. Electron beam computed tomography and multislice computed tomography with calcium score software seem to have an important role in the early diagnosis of coronary artery disease. Coronary calcium is associated with a high probability of subclinical atherosclerosis. In particular the area of calcification has a positive correlation with the histologically analyzed area of the atheromatous burden plaque. The pathophysiological mechanism may be that the calcium adherent to the plaque makes unstable the plaque with possible rupture. Several studies have analyzed the predictive value of calcium score in various subgroups of patients (asymptomatic, with chest pain, with diabetes) and they have confirmed the presence of large calcific deposits in subjects with a high cardiovascular risk. The correlation of the other risk factors with calcium score is unclear and whether this is due to genetic predisposition requires further investigation. © 2003 CEPI Srl

    The EMSO Generic Instrument Module (EGIM): standardized and interoperable instrumentation for ocean observation

    Get PDF
    The oceans are a fundamental source for climate balance, sustainability of resources and life on Earth, therefore society has a strong and pressing interest in maintaining and, where possible, restoring the health of the marine ecosystems. Effective, integrated ocean observation is key to suggesting actions to reduce anthropogenic impact from coastal to deep-sea environments and address the main challenges of the 21st century, which are summarized in the UN Sustainable Development Goals and Blue Growth strategies. The European Multidisciplinary Seafloor and water column Observatory (EMSO), is a European Research Infrastructure Consortium (ERIC), with the aim of providing long-term observations via fixed-point ocean observatories in key environmental locations across European seas from the Arctic to the Black Sea. These may be supported by ship-based observations and autonomous systems such as gliders. In this paper, we present the EMSO Generic Instrument Module (EGIM), a deployment ready multi-sensor instrumentation module, designed to measure physical, biogeochemical, biological and ecosystem variables consistently, in a range of marine environments, over long periods of time. Here, we describe the system, features, configuration, operation and data management. We demonstrate, through a series of coastal and oceanic pilot experiments that the EGIM is a valuable standard ocean observation module, which can significantly improve the capacity of existing ocean observatories and provides the basis for new observatories. The diverse examples of use included the monitoring of fish activity response upon oceanographic variability, hydrothermal vent fluids and particle dispersion, passive acoustic monitoring of marine mammals and time series of environmental variation in the water column. With the EGIM available to all the EMSO Regional Facilities, EMSO will be reaching a milestone in standardization and interoperability, marking a key capability advancement in addressing issues of sustainability in resource and habitat management of the oceans.This work was funded by the project EMSODEV (Grant agreement No 676555) supported by DG Research and Innovation of the European Commission under the Research Infrastructures Programme of the H2020.

    Special issue 9th MARTECH: International Workshop on Marine Technology: 16-18 June 2021, Vigo, Spain.-- 2 pages, 1 figureThe European Multidisciplinary Seafoor and water Column Observatory (EMSO, www.emso.eu) is a distributed research infrastructure (RI), composed of fxed-point deep-sea observatories and shallow water test sites at strategic environmental locations from the southern entrance of the Arctic Ocean all the way through the North Atlantic through the Mediterranean to the Black Sea. Working as a single powerful system, it is a valuable new tool for researchers and engineers looking for long time series of high-quality and high-resolution data to study and continuously monitor complex processes interactions among the geosphere, biosphere, hydrosphere and atmosphere, as well as to test, validate and demonstrate new marine technologiesPeer reviewe

    The Stromboli geophysical experiment. Preliminary report on wide angle refraction seismics and morphobathymetry of Stromboli island (Southern Tyrrhenian sea, Italy)based on integrated offshore-onshore data acquisition (cruise STRO-06 R/V Urania)

    The Stromboli geophysical experiment, performed to acquire onshore and offshore seismic data through a combined on-land and marine network, was finalized to reconstruct the seismic tomography of the volcano and to investigate the deep structures and the location of magma chambers. A detailed swath bathymetry around the volcano has also been acquired by the R/V Urania Multibeam. In particular, high resolution bathymetry of the ’Sciara del Fuoco’ area allows to image the present-day seafloor setting of the area involved by the submarine slide of 2002-12-30. During the experiment wide angle refraction seismics was performed all around the Stromboli volcano by a 4 GI-GUN tuned array. The data were recorded by the permanent seismic network of the INGV and 20 temporary stations and 10 OBS deployed on the SE, SW and NE submerged flanks of the volcano after detailed morpho-bathymetric analysis
