Abstract
BACKGROUND Much of the morbidity and mortality associated with ventricular assist devices (VADs) is due to haemorrhagic and thrombotic complications. To manage antithrombotic therapy, interactions between the patient and pump should be better understood. METHODS We have compared the Jarvik 2000, an axial flow left ventricular assist device (LVAD), with the HeartWare ventricular assist device (HVAD) centrifugal pump, regarding conventional laboratory findings, thromboelastometric and aggregometric tests. RESULTS Patients with the Jarvik 2000 experienced a significant reduction in platelet count following implantation, a phenomenon not seen with the HeartWare model. Conversely, we observed that levels of platelet activation, as assessed by a platelet function analyzer, and activation of the coagulation system, as assessed by thromboelastometry, were significantly greater in the HeartWare group. CONCLUSIONS It seems that axial flow pumps, being more destructive on blood cells, tend to reduce platelet numbers. On the other hand, centrifugal flow is associated with a hypercoagulable state, possibly resulting from the activation of the coagulation system in the absence of platelet destruction.

Abstract
AIM Current Italian legislation obliges employers to prevent workers who are occupationally at risk or who perform jobs that may be hazardous for the safety or health of third parties from consuming alcohol. The LaRA Group undertook to assess whether the law fully safeguards the health and safety of both workers and third parties, without impinging upon the civil rights of workers. METHOD A written document expressing agreement was produced following discussions between doctors, lawyers, bioethicists and social partners. RESULTS There are gaps and inconsistencies in current laws; the differences in local and regional provisions prevent authorities from applying a single strategy at national level. There should be a change in existing rules under which the employer's obligation to enforce the ban on consumption alcohol in the workplace is enacted solely by the "competent" physician whose institutional role is to safeguard and promote health. Some occupational categories that are subject to a ban on alcohol consumption do not currently under-go health surveillance. For example, if road transport drivers are not exposed to a specific occupational risk foreseen under another law, they can be placed under health surveillance only in those regions where the local laws contemplate this type of control. In other cases, the practice of assessing the risk to third parties and providing for compulsory health surveillance in the Risk Assessment Document, is considered by some jurists to be a "consuetudo praeter legem" and therefore acceptable in a field not yet covered by a specific law, but to be "contra legem" or unlawful by other jurists. Moreover, the competent physician who uses a breathanalyser or tests for alcohol addiction faces an ethical dilemma, since by communicating the results to an employer or authorities responsible for the issuing of licenses, he may be violating his professional oath of secrecy. Furthermore, the emphasis placed on testing has induced companies and inspectors to overlook educational and rehabilitation aspects. It is essential to involve general practitioners, educators and specialist services in addressing the problems of alcohol abuse so as to inform/train, recover and rehabilitate. The few studies available indicate that the rules are poorly enforced and that non-compliance may go unobserved. CONCLUSIONS The Group urges all employers to assess the risk for third parties caused by alcohol abuse and to devise a policy on alcohol. Controlling alcohol-related risks in the workplace calls for a better definition of the roles of Vigilance Bod-ies and Company Physicians together with a shift from a reactive to a proactive attitude of all the parties involved.

Abstract
OBJECTIVE The cingulate cortex is a functionally heterogeneous region involved in diverse cognitive and emotional processes. It is a region of special interest to investigate the neurological substrate of schizophrenia. The aim of this paper is to review all the studies that investigated the relation between the cingulate cortex and two of the most important and little known areas of this disease: the psychotic onset and the negative symptoms. MATERIAL AND METHODS Relevant literature was identified through a search in PubMed, Web of Science, and Cochrane database. Search terms included negative symptoms, cingulate cortex, cingulate gyrus, schizophrenia, PET, SPECT, MRI, fMRI, BOLD, deficit schizophrenia, early-onset schizophrenia, psychotic onset, psychosis. RESULTS 9 studies evidenced a link between negative symptoms and hypoactivity of cingulate cortex, whereas 7 studies did not. A positive relationship between anterior cingulate cortex gray matter thinning and high risk for schizophrenia is well characterized in literature. CONCLUSIONS In a large portion of patients hypoactivity of cingulate cortex underlie the presence of negative symptoms. In particular, ACC (anterior cingulated cortex) thinning seems to be related to the increasing social withdrawal that is characteristic of the psychosis prodrome. New therapies focused on the brain stimulation of the cingulate cortex could represent an important aid for patients with this kind of symptoms.

Abstract
Silver nanoparticles (AgNPs) were biosynthesised by a Klebsiella oxytoca strain BAS-10, which, during its growth, is known to produce a branched exopolysaccharide (EPS). Klebsiella oxytoca cultures, treated with AgNO3 and grown under either aerobic or anaerobic conditions, produced silver nanoparticles embedded in EPS (AgNPs-EPS) containing different amounts of Ag(0) and Ag(I) forms. The average size of the AgNPs-EPS was determined by transmission electron microscopy, while the relative abundance of Ag(0)- or Ag(I)-containing AgNPs-EPS was established by scanning electrochemical microscopy (SECM). Moreover, the release of silver(I) species from the various types of AgNPs-EPS was investigated by combining SECM with anodic stripping voltammetry. These measurements allowed obtaining information on the kinetic of silver ions release from AgNPs-EPS and their concentration profiles at the substrate/water interface.

Abstract
In a patient with a lesion of the right amygdala and temporal pole who had the characteristics of the gourmand syndrome, sensory and hedonic testing was performed to examine the processing of taste, olfactory, and some emotional stimuli. The gourmand syndrome describes a preoccupation with food and a preference for fine eating and is associated with right anterior lesions. It was found that the taste thresholds for sweet, salt, bitter, and sour were normal; that the patient did not dislike the taste of salt (NaCl) at low and moderate concentrations as much as age-matched controls; that this also occurred for monosodium glutamate (MSG); that there were some olfactory differences from normal controls; and that there was a marked reduction in the ability to detect face expressions of disgust.

Abstract
Mechanical support by means of ventricular assist devices is at present the most promising alternative of efforts aimed at increasing the supply of donor organs. The support of the left dysfunctional ventricle enables appropriate haemodynamic stabilization and recovery of secondary organ failure, often present in these severely ill patients. The current results of left ventricular assist device (LVAD) therapy for bridge to transplantation are excellent when compared with the outcome without the availability of this therapy. Additionally, a rapid extubation of these patients has demonstrated to be efficient in cardiac surgery for faster recovery and rehabilitation. Consequently, in recent years, surgical objectives have become much more clearly defined, and the concept of less invasive cardiac surgery can be applied to make this operation less complicated, anatomically focused with a greater clinical impact. We describe an LVAD implantation technique, applying the concept of less invasive cardiac surgery, consisting in the association of reduced surgical approaches, off-pump implantation and reduced administration of heparin dose, in order to achieve rapid extubation and rehabilitation of the patient, preserving low morbidity, and still meeting all the goals of the standard procedure.

Abstract
Left ventricular assist device implantation might require extensive surgical incision and use of cardiopulmonary bypass. Less invasive implantation using smaller incision and extracorporeal membrane oxygenation perfusion in critically ill patients can decrease the rate of complications. One patient with cardiomyopathy received the Jarvik 2000 FlowMaker through an upper T-inverted ministernotomy and left minithoracotomy. The outflow-graft was connected to the ascending aorta, and the Jarvik 2000 was inserted through the apex of the left ventricle on beating heart. The power cable was routed percutaneously through the neck to a retroauricular skull-mounted pedestal.

Abstract
A mechanism of mercury detoxification has been suggested by a previous study on Hg bioaccumulation in Manila clams (Ruditapes philippinarum) in the polluted Marano and Grado lagoons and in this study we demonstrate that this event could be partly related to the detoxifying activities of Hg-resistant bacteria (MRB) harbored in clam soft tissues. Therefore, natural clams were collected in six stations during two different periods (winter and spring) from Marano and Grado Lagoons. Siphons, gills and hepatopancreas from acclimatized clams were sterile dissected to isolate MRB. These anatomical parts were glass homogenized or used for whole, and they were lying on a solid medium containing 5mgl(-1) HgCl2 and incubated at 30°C. A total of fourteen bacterial strains were isolated and were identified by 16S rDNA sequencing and analysis, revealing that strains were representative of eight bacterial genera, four of which were Gram-positive (Enterococcus, Bacillus, Jeotgalicoccus and Staphylococcus) and other four were Gram-negative (Stenotrophomonas, Vibrio, Raoultella and Enterobacter). Plasmids and merA genes were found and their sequences determined. Fluorescence in situ hybridization (FISH) technique shows the presence of Firmicutes, Actinobacteria and Gammaproteobacteria by using different molecular probes in siphon and gills. Bacterial clumps inside clam flesh were observed and even a Gram-negative endosymbiont was disclosed by transmission electronic microscope inside clam cells. Bacteria harbored in cavities of soft tissue have mercury detoxifying activity. This feature was confirmed by the determination of mercuric reductase in glass-homogenized siphons and gills.

Abstract
Tissue engineering of heart valves investigates the possibility to create a fully compatible and biomimetic graft able to provide host cell repopulation like the native living valve. Decellularized aortic and pulmonary valves and synthetic polymers have been used to promote the creation of a native-like scaffold suitable to be colonized by cells either in vitro, in dynamic bioreactors or in vivo using different animal models. The herein presented research provides the intra-operative protocol and details of surgical technique. Porcine aortic valve conduits were decellularized and implanted in the right ventricular outflow tract of Vietnamese pigs.

Abstract
Association mapping of the central part of porcine chromosome 2 harboring QTLs for carcass and meat quality traits was performed with 17 gene-tagged SNPs located between 44.0 and 77.5 Mb on a physical map (Sscrofa10.2) in Italian Large White pigs. For the analyzed animals records of estimated breeding values for average daily gain, back fat thickness, lean cuts, ham weight, feed conversion ratio, pH1, pHu, CIE L*, CIE a*, CIE b* and drip loss were available. A significant QTL for fat deposition (adjusted P=0.0081) and pH1 (adjusted P=0.0972) to MYOD1 at position 44.4 Mb and a QTL for growth and meatiness (adjusted P=0.0238-0.0601) to UBL5 at position 68.9 Mb were mapped. These results from association mapping are much more accurate than those from linkage mapping and facilitate further search for position candidate genes and causative mutations needed for application of markers through marker assisted selection.
