Abstract
Abstract
A collaborative study was conducted for the determination of paralytic shellfish poisoning (PSP) toxins in shellfish. The method used liquid chromatography with fluorescence detection after prechromatographic oxidation of the toxins with hydrogen peroxide and periodate. The PSP toxins studied were saxitoxin (STX), neosaxitoxin (NEO), gonyautoxins 2 and 3 (GTX2,3; together), gonyautoxins 1 and 4 (GTX1,4; together), decarbamoyl saxitoxin (dcSTX), B-1 (GTX5), C-1 and C-2 (C1,2; together), and C-3 and C-4 (C3,4; together). B-2 (GTX6) toxin was also included, but for qualitative identification only. Mussels, both blank and naturally contaminated, were mixed and homogenized to provide a variety of PSP toxin mixtures and concentration levels. The same procedure was followed with clams, oysters, and scallops. Twenty-one test samples in total were sent to 21 collaborators who agreed to participate in the study. Results were obtained from 18 laboratories representing 14 different countries. It is recommended that the method be adopted First Action by AOAC INTERNATIONAL.

Abstract
Yessotoxin (YTX) and its analogues are a newly recognized group of toxins with increased presence in shellfish in recent years. They can be quantified by various functional assays due to their interaction with phosphodiesterases (PDEs). One of these assays detects the binding between the YTX and the fluorescently labeled PDE I using fluorescence polarization, a spectroscopic technique based on exciting a fluorescent molecule with plane-polarized light and measuring the polarization degree of the emitted light. The aim of this study was to develop a YTX extraction procedure from mussels that does not interfere with this detection method. YTX concentrations were measured in spiked mussel extracts obtained through use of different extraction methods and cleaning procedures. The percentages of toxin recovery in various steps of the processes were calculated using these concentrations. Six extraction methods and two cleaning steps were used and no matrix effects and high toxin recoveries were obtained in two cases. One case used acetone as extraction solvent followed by three dichloromethane partitions and the other case used methanol. The cleaning procedure includes a silica cartridge and a 10,000 NMWL filter. Finally these two extraction-cleaning-detection methods were applied to a naturally contaminated mussel sample and results showed that not only YTX but also homoYTX and hydroxyYTX can be quantified with a 85-90% recovery.

Abstract
The recent discovery of cardiac endocrine function, together with the development of accurate and feasible assay methods for cardiac natriuretic hormone evaluation, i.e. for B-type natriuretic peptide (BNP) and inactive peptide NT-proBNP have confirmed their pathophysiological and clinical significance for cardiovascular disease assessment. Concerning heart failure, their value is for diagnostic screening in selected/unselected populations, for differential diagnosis of dyspnea and for prognostic stratification, and as a guide for follow-up and treatment of patients. Recent Italian recommendations pointed out that BNP/NT-proBNP has a role in ruling-out the diagnosis of heart failure in patients with dubious signs/symptoms: plasma BNP/NT-proBNP concentrations help in the clinical evaluation of chronic heart failure patients when risk stratification is needed, whereas the routine BNP/NT-proBNP assay is still not recommended to guide therapeutic decision-making.

Abstract
The toxicity of okadaic acid (OA) and yessotoxins (YTXs) was studied in mice orally fed on (i) OA (17.80+/-2.41 microg/kg) for 24 h and mouse feed for 24 h; (ii) OA (17.2+/-2.13 microg/kg) plus YTXs (1.30+/-0.12 mg/kg) for 24 h and mouse feed for 24 h; (iii) OA (18.88+/-1.86 microg/kg) plus YTXs (1.45+/-0.12 mg/kg) for 24 h. After toxin treatments the thymus and spleen were examined. More severe morpho-functional modifications were found in the thymus, which presented atrophy, a significant depletion in the lymphoid compartment and angiogenesis. In spite of the impairment, a number of inflammatory cells, reactive to anti-cytokine antibodies, were recruited. Moreover, greater expression of matrix metalloproteinase-9, particularly in cells located near new blood vessels, was observed. Thymus injury was still observed after 48 h. Histopathological changes to the spleen were more evident in mice orally treated for 24 h and immediately sacrificed. The organ showed a significant loss of volume and a fibrous component invaded regions involved in immune functions. In white pulp the marginal zones were reduced, lymphoid nodules contained large germinal centres and the periarteriolar lymphoid sheaths showed cellular depletion. An inflammatory cell response was activated by the recruitment of granulocytes, an increased number of active macrophages and increased immunoreactivity to cytokines. Unlike in the thymus, some evidence of recovery was seen in the spleen. The data suggest that low oral doses of OA alone or OA plus YTXs are able to provoke immunostimulation and systemic immunotoxicity, thus also indicative of tumorigenic properties.

Abstract
Histological and immunocytochemical investigations were performed on different organs (brain, duodenum and thymus) of mice following lethal (420 microg/kg) or sublethal (10 microg/kg) intraperitoneal injection of yessotoxin (YTX). No morpho-functional modifications were observed in large neurons of the cerebral and cerebellar cortex with the sub-lethal dose, nor in the cerebral cortex with the lethal dose. The duodenum also did not show significant alterations. However, there was an inflammation response to the toxin, in which blood cells and cytokines were involved. This was more evident with the lethal YTX dose. The thymus and, in general, the immune system are the main targets of YTX at both the concentrations used. Furthermore, the alterations present in the thymus may support tumorigenic implications.

Abstract
Swiss CD1 mice died less than 2 h after intraperitoneal injection of 420 microg/kg of algal yessotoxin (YTX). The morphological, histochemical and immunocytochemical studies performed on the cerebellar cortex revealed damage to the Purkinje cells. The main cytological alterations were observed in the cytoplasm, while less sufferance was detected in the nucleus. The immunocytochemical experiments showed an increased positivity to S100 protein while there was a decreased response to calbindin D-28K, beta-tubulin and neurofilaments. These changes in intracellular Ca(2+)-binding proteins and the modifications in the cytoskeletal components of Purkinje cells suggest that YTX may be involved in neurological disorders.

Abstract
Marine biotoxins, more or less complex molecules with various origins that can accumulate in the tissues of fish products through the food chain, are reviewed. The EU, aware of the danger incurred in eating certain fish products, has issued a set of hygiene and health directives for the purpose of preventing disease and safeguarding consumer health. In particular, directive 91/492/EEC, of 15 July 1991, lays down the sanitary norms applicable to the production and commercialization of live bivalve molluscs, echinoderms, tunicates and marine gastropods and regulates the whole system involving these products from their origin to consumption. More recently, through Commission Decision dated 15 March 2002 (EC OJ 175/62 of 16.3.2002) the EU has set new standards for the implementation of directive 91/492/EEC with respect to the maximum levels and analysis methods for some marine biotoxins.

Abstract
This study reports, for the first time, immunocytochemical evidence of the distribution of algal yessotoxins (YTXs) in the mussel Mytilus galloprovincialis. Immunopositivity to YTXs was found in immunocytes and in the digestive gland. With regards the gland, the positivity was mainly present in the lumen of both tubules and ducts. No YTXs were detected in the gonads, while the presence of toxins in the gills cannot be excluded. The data are supported by both HPLC analysis and functional assays.

Abstract
A detailed analysis of the toxic composition in the hepatopancreas of mussels from northern Adriatic sea has been performed. Along with some polyether toxins of DSP (diarrhetic shellfish poisoning) type, such as yessotoxin and its analogues, which are responsible for a variety of human seafood poisonings throughout the world, we have now isolated a new type of toxin, the chlorosulfolipid 1, which is completely different in structure from the polyether DSP-toxins isolated so far. The structural determination of the new toxin, including its absolute stereochemistry, has been performed by extensive NMR analysis and molecular mechanics and dynamics calculations.

Abstract
A high sensitivity bioassay able to recognise small amounts of paralytic and amnesic toxins in algal acetic extracts is described. The method is based on the measure of intracellular [Ca(2+)](i) in primary cultures of rat cortical neurones preloaded with Fura-2 and submitted to electrical field stimulation. Under normal conditions the basal [Ca(2+)](i) level was about 50-100 nM and was nearly doubled during the peaks induced by trains of electrical pulses at 10 Hz for 10 s. Saxitoxin (STX) 3.5 nM and tetrodotoxin (TTX) 24 nM halved the peaks height without affecting basal [Ca(2+)](i). Conversely, domoic acid increased the basal [Ca(2+)](i) (EC(50)=3. 7 microM) and decreased the calcium peaks (EC(50)=7.3 microM). CNQX (a competitive antagonist of AMPA/KA receptors) at 10 microM shifted to the right by a factor of 3 the concentration-response curves of domoic acid. The extracts of non-toxic algae were well tolerated by up to 10 microg protein/ml, whereas extracts of Alexandrium lusitanicum at 1-4 microg protein/ml reduced [Ca(2+)](i) peaks and increased basal calcium levels. This toxic effect of A. lusitanicum was unexpected since parallel HPLC analysis showed only the presence of gonyautoxins, known to act like saxitoxin. Therefore, the bioassay on rat cortical neurones revealed a complex composition of the toxins present in A. lusitanicum. The relevance of fluorimetric detection of [Ca(2+)](i) in primary neuronal cultures in the evaluation of algal risk is stressed.

Abstract
Pectenotoxin-2 (PTX-2), a polyether-lactone included in the neutral class of diarrhoetic shellfish poisoning (DSP) toxins, has been unambiguously detected in Dinophysis fortii collected in the northern Adriatic Sea (Emilia Romagna coasts). This is the first report of such a toxin in Europe. This lipid soluble toxin was identified both in crude methanolic phytoplankton extract and in the neutral fraction obtained by extract chromatography on a basic alumina column. The techniques used were reversed phase high-performance liquid chromatography followed either by UV diode-array detection (LC-UV-DAD) or by mass spectrometry (LC-MS) and tandem mass spectrometry (LC-MS-MS) using an atmospheric-pressure ionization source and an ionspray interface. Okadaic acid (OA) was also found in the D. fortii specimens and quantified as 15 pg/cell. Although quantitation of PTX-2 was not possible due to the lack of pure toxin, the high PTX-2:OA ratio suggested PTX-2 was significant in the D. fortii specimens. The presence of PTX-2 in a region with no previous report of DSP neutral toxic compounds may indicate a risk of human poisoning. Serious efforts should therefore be made to develop suitable routine methods capable of detecting the presence of PTXs in biological materials of marine origin, in order to assure the wholesomeness of seafood products.

Abstract
In this study, monitoring of marine biotoxins in "mucilaginous aggregates" and in mussels from coastal area of Emilia Romagna (Northern Adriatic Sea) in June-August 1988, 1989 and 1991, are reported. Both "mucilaginous aggregates" and mussels were analysed for NSP and PSP in 1988, and ASP, DSP, NSP, PSP in 1989, 1991. Concerning "mucilaginous aggregate" any presence of biotoxins was never detected. In the mussels it was possible to exclude the presence of PSP, ASP and NSP, but very high levels of DSP were shown in all the considered periods, in relation to the presence in the sea water of cells of the Dinophysis genus.

Abstract
The present study describes cause-specific mortality of asbestos cement workers in the Emilia Romagna region of Italy. The cohort included workers in ten factories, most of which started operating between 1955 and 1965. Asbestos, mainly chrysotile, constituted 10%-20% of the dry component of the mixture. Crocidolite range between 5% and 50% of total asbestos. Asbestos concentrations up to 44 ff/cc were reported prior to 1975, while in recent years they have usually been below 0-1 ff/cc. The cohort included 3341 workers who had at some time been employed in the ten factories under study. Their mortality experience was compared with that of the population resident in Emilia Romagna. Vital status was ascertained at 1989. Seventy-three subjects were lost to follow-up (2.2%). Mortality from all causes and from all types of cancer was increased in the cohort. Malignant neoplasms of the respiratory tract showed a significant increase (SMR: 134; 90% confidence interval: 101-175; 40 observed) due to lung cancer (SMR: 124; 90% confidence interval: 91-166; 33 observed) and neoplasms of the pleura, mediastinum, and other parts of the respiratory tract (SMR: 602; 90% confidence interval 237-1267; 5 observed). The discrepancy between observed and expected mortality mainly concerned subjects with at least 20 years of employment in the factories. Five more cases of histologically confirmed mesothelioma occurred after the end of follow-up.

Abstract
The concentrations of heavy metals Hg, Pb and Cd found in zooplankton samples collected in two stations off Cesenatico (Northern Adriatic Sea) from March 1978 to January 1979, have been reported. The Hg, Pb and Cd concentrations showed large variations which did not seem to be correlated with taxonomic composition. The detected levels of metals were higher at the offshore than the nearshore station, accordingly with the sediment pattern. The high concentration of Hg were apparently associated with sources of local industrial pollution.

Abstract
Numerous researches have been done on this subject. The Swiss Academy of Medical Sciences as well as the European Council have prepared guidelines that are very clear. However what is lacking is an adequate preparation of the physicians and nursing personnel concerning attitudes. This inadequate preparation is a major reason for the violation of the dying patients rights. Accompanying the dying and his family requires on extensive knowledge of oneself and especially of the patient. It also requires patience, honesty, trust, humility, hope and courage. The mentioned characteristics, described by the American philosopher Milton Mayeroff, are indispensable to the professional who really wants to "care" for the other person. Today, we need to provide specific training in order for young physicians to develop these characteristics.
