Abstract
SOD1 gene is associated with progressive motor neuron degeneration in the familiar forms of amyotrophic lateral sclerosis. Although studies on mutant human SOD1 transgenic rodent models have provided important insights into disease pathogenesis, they have not led to the discovery of early biomarkers or effective therapies in human disease. The recent generation of a transgenic swine model expressing the human pathological hSOD1G93A gene, which recapitulates the course of human disease, represents an interesting tool for the identification of early disease mechanisms and diagnostic biomarkers. Here, we analyze the activation state of CNS cells in transgenic pigs during the disease course and investigate whether changes in neuronal and glial cell activation state can be reflected by the amount of extracellular vesicles they release in biological fluids. To assess the activation state of neural cells, we performed a biochemical characterization of neurons and glial cells in the spinal cords of hSOD1G93A pigs during the disease course. Quantification of EVs of CNS cell origin was performed in cerebrospinal fluid and plasma of transgenic pigs at different disease stages by Western blot and peptide microarray analyses. We report an early activation of oligodendrocytes in hSOD1G93A transgenic tissue followed by astrocyte and microglia activation, especially in animals with motor symptoms. At late asymptomatic stage, EV production from astrocytes and microglia is increased in the cerebrospinal fluid, but not in the plasma, of transgenic pigs reflecting donor cell activation in the spinal cord. Estimation of EV production by biochemical analyses is corroborated by direct quantification of neuron- and microglia-derived EVs in the cerebrospinal fluid by a Membrane Sensing Peptide enabled on-chip analysis that provides fast results and low sample consumption. Collectively, our data indicate that alteration in astrocytic EV production precedes the onset of disease symptoms in the hSODG93A swine model, mirroring donor cell activation in the spinal cord, and suggest that EV measurements from the cells first activated in the ALS pig model, i.e. OPCs, may further improve early disease detection.

Abstract
Modifications of the cationic head and the ethylene linker of 2-(triethylammonium)ethyl ether of 4-stilbenol (MG624) have been proved to produce selective α9*-nAChR antagonism devoid of any effect on the α7-subtype. Here, single structural changes at the styryl portion of MG624 lead to prevailing α7-nAChR antagonism without abolishing α9*-nAChR antagonism. Nevertheless, rigidification of the styryl into an aromatic bicycle, better if including a H-bond donor NH, such as 5-indolyl (31), resulted in higher and more selective α7-nAChR affinity. Hybridization of this modification with the constraint of the 2-triethylammoniumethyloxy portion into (R)-N,N-dimethyl-3-pyrrolidiniumoxy substructure, previously reported as the best modification for the α7-nAChR affinity of MG624 (2), was a winning strategy. The resulting hybrid 33 had a subnanomolar α7-nAChR affinity and was a potent and selective α7-nAChR antagonist, producing at the α7-, but not at the α9*-nAChR, a profound loss of subsequent ACh function.

Abstract
We examined effects of exposing female and male mice for 33 weeks to 45% or 60% high fat diet (HFD). Males fed with either diet were more vulnerable than females, displaying higher and faster increase in body weight and more elevated cholesterol and liver enzymes levels. Higher glucose metabolism was revealed by PET in the olfactory bulbs of both sexes. However, males also displayed altered anterior cortex and cerebellum metabolism, accompanied by a more prominent brain inflammation relative to females. Although both sexes displayed reduced transcripts of neuronal and synaptic genes in anterior cortex, only males had decreased protein levels of AMPA and NMDA receptors. Oppositely, to anterior cortex, cerebellum of HFD-exposed mice displayed hypometabolism and transcriptional up-regulation of neuronal and synaptic genes. These results indicate that male brain is more susceptible to metabolic changes induced by HFD and that the anterior cortex versus cerebellum display inverse susceptibility to HFD.

Abstract
Nicotinic acetylcholine receptors containing α9 subunits (α9*-nAChRs) are potential druggable targets arousing great interest for pain treatment alternative to opioids. Nonpeptidic small molecules selectively acting as α9*-nAChRs antagonists still remain an unattained goal. Here, through modifications of the cationic head and the ethylene linker, we have converted the 2-triethylammonium ethyl ether of 4-stilbenol (MG624), a well-known α7- and α9*-nAChRs antagonist, into some selective antagonists of human α9*-nAChR. Among these, the compound with cyclohexyldimethylammonium head (7) stands out for having no α7-nAChR agonist or antagonist effect along with very low affinity at both α7- and α3β4-nAChRs. At supra-micromolar concentrations, 7 and the other selective α9* antagonists behaved as partial agonists at α9*-nAChRs with a very brief response, followed by rebound current once the application is stopped and the channel is disengaged. The small or null postapplication activity of ACh seems to be related to the slow recovery of the rebound current.

Abstract
Neuronal nicotinic acetylcholine receptors containing the α9 or the α9 and α10 subunits are expressed in various extra-neuronal tissues. Moreover, most cancer cells and tissues highly express α9-containing receptors, and a number of studies have shown that they are powerful regulators of responses that stimulate cancer processes such as proliferation, inhibition of apoptosis, and metastasis. It has also emerged that their modulation is a promising target for drug development. The aim of this review is to summarize recent data showing the involvement of these receptors in controlling the downstream signaling cascades involved in the promotion of cancer.

Abstract
Background Asthma, and severe asthma in particular, is often managed within a specialized field with allergists and clinical immunologists playing a leading role. In this respect, the National Scientific Society SIAAIC (Società Italiana di Allergologia, Asma ed Immunologia Clinica), structured in Regional and Inter-Regional sections, interviewed a large number of specialists involved in the management of this respiratory disease. Methods A survey entitled “Management of patients with asthma and severe asthma” based on 17 questions was conducted through the SIAAIC newsletter in 2019 thanks to the collaboration between GlaxoSmithKline S.p.A. and the Inter-Regional Section of SIAAIC of Central Italy. Results Fifty-nine allergists and clinical immunologists participated to the survey, and 40 of them completed the entire questionnaire. Almost all of the specialists (88%) reported that asthma control was achieved in above 50% of their patients, even if only one third (32%) actually used validated clinical tools such as asthma control test (ACT). Poor adherence to inhaled therapy was recognized as the main cause of asthma control failure by 60% of respondents, and 2–5 min on average is dedicated to the patient inhaler technique training by two-thirds of the experts (65%). Maintenance and as-needed therapy (SMART/MART) is considered an appropriate approach in only a minority of the patients (25%) by one half of the respondents (52%). A high number of exacerbations despite the maximum inhalation therapy were recognized as highly suspicious of severe asthma. Patients eligible for biological therapies are 3–5% of the patients, and almost all the responders (95%) agreed that patients affected by severe asthma need to be managed in specialized centers with dedicated settings. Biological drugs are generally prescribed after 3–6 months from the initial access to the center, and once started, the follow-up is initially programmed monthly, and then every 3–6 months after the first year of treatment (96% of responders). After phenotyping and severity assessment, comorbidities (urticaria, chronic rhinosinusitis with or without nasal polyps, vasculitis, etc.) are the drivers of choice among the different biological drugs. In the management of severe asthma, general practitioners (GPs) should play a central role in selecting patients and referring them to specialized centers while Scientific Societies should train GPs to appropriately recognize difficult asthma and promote public disease awareness campaigns. Conclusions This survey which collects the point of view of allergists and clinical immunologists from Central Italy highlights that asthma control is still not measured with validated instruments. There is a general consensus that severe asthma should be managed only in dedicated centers and to this aim it is essential to encourage patient selection from a primary care setting and develop disease awareness campaigns for patients.

Abstract
Recently, a strong correlation between metabolic disorders, tumor onset, and progression has been demonstrated, directing new therapeutic strategies on metabolic targets. OLR1 gene encodes the LOX-1 receptor protein, responsible for the recognition, binding, and internalization of ox-LDL. In the past, several studied, aimed to clarify the role of LOX-1 receptor in atherosclerosis, shed light on its role in the stimulation of the expression of adhesion molecules, pro-inflammatory signaling pathways, and pro-angiogenic proteins, including NF-kB and VEGF, in vascular endothelial cells and macrophages. In recent years, LOX-1 upregulation in different tumors evidenced its involvement in cancer onset, progression and metastasis. In this review, we outline the role of LOX-1 in tumor spreading and metastasis, evidencing its function in VEGF induction, HIF-1alpha activation, and MMP-9/MMP-2 expression, pushing up the neoangiogenic and the epithelial-mesenchymal transition process in glioblastoma, osteosarcoma prostate, colon, breast, lung, and pancreatic tumors. Moreover, our studies contributed to evidence its role in interacting with WNT/APC/β-catenin axis, highlighting new pathways in sporadic colon cancer onset. The application of volatilome analysis in high expressing LOX-1 tumor-bearing mice correlates with the tumor evolution, suggesting a closed link between LOX-1 upregulation and metabolic changes in individual volatile compounds and thus providing a viable method for a simple, non-invasive alternative monitoring of tumor progression. These findings underline the role of LOX-1 as regulator of tumor progression, migration, invasion, metastasis formation, and tumor-related neo-angiogenesis, proposing this receptor as a promising therapeutic target and thus enhancing current antineoplastic strategies.

Abstract
A series of diastereomeric 2-(2-pyrrolidinyl)-1,4-benzodioxanes bearing a small, hydrogen-bonding substituent at the 7-, 6-, or 5-position of benzodioxane have been studied for α4β2 and α3β4 nicotinic acetylcholine receptor affinity and activity. Analogous to C(5)H replacement with N and to a much greater extent than decoration at C(7), substitution at benzodioxane C(5) confers very high α4β2/α3β4 selectivity to the α4β2 partial agonism. Docking into the two receptor structures recently determined by cryo-electron microscopy and site-directed mutagenesis at the minus β2 side converge in indicating that the limited accommodation capacity of the β2 pocket, compared to that of the β4 pocket, makes substitution at C(5) rather than at more projecting C(7) position determinant for this pursued subtype selectivity.

Abstract
Glioblastomas (GBMs), the most frequent and aggressive human primary brain tumours, have altered cell metabolism, and one of the strongest indicators of malignancy is an increase in choline compounds. Choline is also a selective agonist of some neuronal nicotinic acetylcholine receptor (nAChR) subtypes. As little is known concerning the expression of nAChR in glioblastoma cells, we analysed in U87MG human grade-IV astrocytoma cell line and GBM5 temozolomide-resistant glioblastoma cells selected from a cancer stem cell-enriched culture, molecularly, pharmacologically and functionally which nAChR subtypes are expressed and,whether choline and nicotine can affect GBM cell proliferation. We found that U87MG and GBM5 cells express similar nAChR subtypes, and choline and nicotine increase their proliferation rate and activate the anti-apoptotic AKT and pro-proliferative ERK pathways. These effects are blocked by the presence of non-cell-permeable peptide antagonists selective for α7- and α9-containing nicotinic receptors. siRNA-mediated silencing of α7 or α9 subunit expression also selectively prevents the effects of nicotine and choline on GBM cell proliferation. Our findings indicate that nicotine and choline activate the signalling pathways involved in the proliferation of GBM cells, and that these effects are mediated by α7 and α9-containing nAChRs. This suggests that these nicotinic receptors may contribute to the aggressive behaviour of this tumor and may indicate new therapeutic strategies against high-grade human brain tumours.

Abstract
We provide a database of the surface ruptures produced by the 26 December 2018 Mw 4.9 earthquake that struck the eastern flank of Mt. Etna volcano in Sicily (southern Italy). Despite its relatively small magnitude, this shallow earthquake caused about 8 km of surface faulting, along the trace of the NNW-trending active Fiandaca Fault. Detailed field surveys have been performed in the epicentral area to map the ruptures and to characterize their kinematics. The surface ruptures show a dominant right-oblique sense of displacement with an average slip of about 0.09 m and a maximum value of 0.35 m. We have parsed and organized all observations in a concise database, with 932 homogeneous georeferenced records. The Fiandaca Fault is part of the complex active Timpe faults system affecting the eastern flank of Etna, and its seismic history indicates a prominent surface-faulting potential. Therefore, this database is essential for unravelling the seismotectonics of shallow earthquakes in volcanic areas, and contributes updating empirical scaling regressions that relate magnitude and extent of surface faulting.

Abstract
Adenocarcinoma and glioblastoma cell lines express α7- and α9α10-containing nicotinic acetylcholine receptors (nAChRs), whose activation promotes tumor cell growth. On these cells, the triethylammoniumethyl ether of 4-stilbenol MG624, a known selective antagonist of α7 and α9α10 nAChRs, has antiproliferative activity. The structural analogy of MG624 with the mitocan RDM-4'BTPI, triphenylphosphoniumbutyl ether of pterostilbene, suggested us that molecular hybridization among their three substructures (stilbenoxy residue, alkylene linker, and terminal onium) and elongation of the alkylene linker might result in novel antitumor agents with higher potency and selectivity. We found that lengthening the ethylene bridge in the triethylammonium derivatives results in more potent and selective toxicity toward adenocarcinoma and glioblastoma cells, which was paralleled by increased α7 and α9α10 nAChR antagonism and improved ability of reducing mitochondrial ATP production. Elongation of the alkylene linker was advantageous also for the triphenylphosphonium derivatives resulting in a generalized enhancement of antitumor activity, associated with increased mitotoxicity.

Abstract
Neuronal nicotinic acetylcholine receptors (nAChRs) belong to a super-family of Cys-loop ligand-gated ion chan-nels that respond to endogenous acetylcholine (ACh) or other cholinergic ligands. These receptors are also the targets of drugs such as nicotine (the main addictive agent delivered by cigarette smoke) and are involved in a variety of physiological and pathophysiological processes. Numerous studies have shown that the expression and/or function of nAChRs is com-promised in many neurological and psychiatric diseases. Furthermore, recent studies have shown that neuronal nAChRs are found in a large number of non-neuronal cell types in-cluding endothelial cells, glia, immune cells, lung epithelia and cancer cells where they regulate cell differentiation, prolifera-tion and inflammatory responses. The aim of this review is to describe the most recent findings concerning the structure and function of native nAChRs inside and outside the nervous system.

Abstract
BACKGROUND AND PURPOSE Tobacco smoke contains many classes of carcinogens and although nicotine is unable to initiate tumourigenesis in humans and rodents, it promotes tumour growth and metastasis in lung tumours by acting on neuronal nicotinic ACh receptors (nAChRs). The aim of this study was to identify molecularly, biochemically and pharmacologically which nAChR subtypes are expressed and functionally activated by nicotine in lung cancer cell lines. EXPERIMENTAL APPROACH We used A549 and H1975 adenocarcinoma cell lines derived from lung tumours to test the in vitro effects of nicotine, and nAChR subtype-specific peptides and compounds. KEY RESULTS The two adenocarcinoma cell lines express distinctive nAChR subtypes, and this affects their nicotine-induced proliferation. In A549 cells, nAChRs containing the α7 or α9 subunits not only regulate nicotine-induced cell proliferation but also the activation of the Akt and ERK pathways. Blocking these nAChRs by means of subtype-specific peptides, or silencing their expression by means of subunit-specific siRNAs, abolishes nicotine-induced proliferation and signalling. Moreover, we found that the α7 antagonist MG624 also acts on α9-α10 nAChRs, blocks the effects of nicotine on A549 cells and has dose-dependent cytotoxic activity. CONCLUSIONS AND IMPLICATIONS These results highlight the pathophysiological role of α7- and α9-containing receptors in promoting non-small cell lung carcinoma cell growth and intracellular signalling and provide a framework for the development of new drugs that specifically target the receptors expressed in lung tumours.

Abstract
BACKGROUND Acute myocardial infarction (AMI), is related to a diffuse active inflammation of the coronary tree associated with rupture of one of the multiple vulnerable plaques. The presence of soluble mediators of inflammation with their synergic or antagonistic actions coordinates the physiological response determining the plaque fate and the fatal event. The present study focus on the cytokines network operating in human coronary plaques of patients died from AMI and controls, pointing out that coronaries of AMI patients produce PTX3 protein twice as that of controls and express high level of PTX3 mRNA. RESULTS The presence of CX3CR1 polymorphisms is significantly correlated with the incidence and the outcome of acute myocardial infarction inducing in the whole coronary tree a strong recruitment of Th1 polarized inflammation that is directly correlated to PTX3 expression. CONCLUSIONS Moreover we found a positive correlation between the expression of PTX3 in the plaque and the content of macrophage cells showing a M2 polarization indicating the possible role of this chemokine as mediator of immune response that would orchestrate plaque evolution and inflammatory cell type activation.

Abstract
In this study we investigated total and hexavalent chromium removal in an h-SSF constructed wetland (CW) planted with Phragmites australis and operating as post-treatment of effluent wastewater from an activated sludge plant serving the textile industrial district of Prato (Italy). Two measurement campaigns were carried out in 2006 and 2008-2010 in which more than 950 inlet and outlet samples were analyzed. When inlet and outlet concentrations were compared one to the other, the latter were found to be significantly lower than the former (p < 0.001); during the entire period of investigation, removal of hexavalent chromium equal to about 70% was achieved. Outlet concentrations ranged between values lower than the quantification limit (0.5 microg L(-1)) and 4.5 microg L(-1), and in all cases were therefore lower than the limit indicated for hexavalent chromium in the Italian regulation for water reuse (5 microg L(-1)). The comparison of the removal efficiencies achieved for hexavalent and trivalent chromium during the two campaigns suggested that the removal of the former can be sustained in the long term, while for the latter, the treatment efficiency is more sensitive to the age of the CW, being that it is it based on trivalent chromium retention in the reed bed.

Abstract
Somatostatin is a peptide hormone that exerts antisecretory and antiproliferative activities on some human tumors. The Ku70/86 heterodimer acts as regulatory subunit of the DNA dependent protein kinase and its DNA binding activity mediates DNA double strands breaks repair that is crucial to maintain the genetic integrity of the genome. The activation of the heterodimer regulates cell cycle progression and the activity of nuclear transcription factors involved in DNA replication and cell proliferation. Moreover Ku86 behaves as a receptor for the growth inhibitory tetradecapeptide, somatostatin. Herein we report that somatostatin treatment to a colon carcinoma cell line (Caco-2) inhibits cell growth and, at same time, strongly modulates the activation of Ku70/86 heterodimer and the levels of Ku86 in the nucleus by increasing its specific mRNA level. Our findings are consistent with the hypothesis that somatostatin controls cell cycle progression and DNA repair through a new signalling pathway that involves the regulation of Ku86 level and modulates the Ku70/86 activity in the nucleus.

Abstract
Allergic disorders are viewed generally as organ diseases and thus referred to organ specialists, such as the ear, nose and throat specialist for rhinitis, the pulmonologist for asthma, the dermatologist for dermatitis, and so on. Indeed, the systemic nature of allergy is made evident by the fact that the same individual may develop during the life different manifestations to a given allergen. This is true for example in sensitisation to house dust mites, which may start in childhood as atopic dermatitis and later express as asthma or rhinitis. The major player in driving the immune response is the T lymphocyte, and the T helper subpopulations--Th1 and Th2--as well as the T regulatory cells, are involved in orienting tolerance or reactivity to allergens. Interesting observations on the systemic or organ-specific actions of T cells were obtained by transplantations from allergic donors to non-allergic recipients. Bone marrow is able to transfer all allergic manifestations, while lung transplantation transfers only asthma. A number of factors are involved in the expression of allergy as a systemic or organ disease and deserve deeper investigations. They include the antigen presenting cells, the homing of T cells, the cytokine and chemokine pattern, and the adhesion molecules.

Abstract
Allergic skin disorders include urticaria, angioedema, contact dermatitis and atopic dermatitis, but the model fitting most closely the systemic concept of allergy is atopic dermatitis (AD), the pathogenesis of which is linked to a complex interaction between skin barrier dysfunction and environmental factors such as allergens and microbes. In particular, an important advance was the demonstration that the mutation of the skin barrier protein filaggrin is related strictly to allergen sensitization and to the development of asthma in subjects with AD. The altered skin barrier function, caused by several factors, results in the passage of allergens through the skin and to systemic responses. A pivotal role in such a response is exerted by Langerhans cells which, via their immunoglobulin E (IgE) receptor, capture the allergens and present them to T cells. When T helper type 2 (Th2) cells are activated, the production of a proinflammatory cytokines and chemokines pattern sustains the persistence of inflammation. Known AD-related cytokines are interleukin (IL)-5, IL-13 and tumour necrosis factor (TNF)-alpha, with emerging importance for IL-17, which seems to drive airway inflammation following cutaneous exposure to antigens, and IL-31, which is expressed primarily in skin-homing Th2 cells. Skin-homing is another crucial event in AD, mediated by the cutaneous lymphocyte-associated antigens (CLA) receptor, which characterizes T cell subpopulations with different roles in AD and asthma.

Abstract
14561 Background: Colon cancer is second only to lung cancer in men and to breast carcinoma in women, for incidence and mortality in western countries .The higher incidence per age is observed between the sixth and seventieth decade, while 60% of the patients survive up to five years. The most important reason for the low percentage of recoveries is due to the fact that when the primary tumour is removed, a high number of patients have already developed micro-metastases, principally at liver. Therefore, methods for early screening are requested. Molecular markers have emerged as an important strategy to evaluate the individual susceptibility for cancer insorgence and for clinical cancer therapy. Recent studies have demonstrated an increase in clusterin expression in breast carcinoma suggesting a possible role of this protein in tumour progression. Clusterin is an heterodimeric (a and β chains) ubiquitous glycoprotein implicated in a large number of physiological processes and in the control of cellular proliferation. Despite the original hypothesis that clusterin is a marker for programmed cell death, several experiments and clinical studies have demonstrated conflicting findings on its role in tumors. Methods: We have studied clusterin isoforms expression in tumour progression, in particular in the adenoma-carcinoma sequence of colorectal cancer. Results: the observation of 35 samples of human intestinal mucosa, such as endoscopic biopsies and surgical specimens, demonstrated that the progression towards high grade and metastatic colon carcinoma leads to a pattern shift of clusterin isoforms production, the complete loss of the proapoptotic nuclear form and an over expression of cytoplasmic secreted form correlateting to a phenotype with high metastatic potential. Moreover we observed in tumor biopsies the release of clusterin in the crypts lumen. The ELISA immuno-dosage of clusterin demonstrated that the sclusterin overexpression in tumours correlates to a significant increase of clusterin in the serum and stools of patients affected by tumoural pathologies and in particular by colorectal cancer. Conclusions: These data suggests a new role of secreted clusterin as a new diagnostic circulating marker and a potential new therapeutic target. No significant financial relationships to disclose.

Abstract
Allergic rhinitis and asthma constitute a global health problem because of their very high prevalence and the consequent burden of disease, concerning medical and economical issues. Among the treatments of allergy, specific immunotherapy has the capacity to favourably alter the natural history of the disease both during and after its performance and thus to reduce the direct and indirect costs of allergic rhinitis and asthma. A number of studies reported such cost reduction for traditional, subcutaneous immunotherapy and recent data demonstrate that also sublingual immunotherapy (SLIT) is associated to economic advantages and/or monetary savings, specifically in terms of reduction of disease economic burden. Only few formal economic assessments of SLIT have been carried out so far, this article will present and discuss the published studies addressed to this issue. The data obtained, although the number of studies is still limited, provide preliminary evidence supporting a SLIT effect on sparing costs for respiratory allergy.

Abstract
The current burden of allergic diseases, estimated by both direct and indirect costs, is very relevant. In fact the cost estimation for rhinitis amount globally to 4-10 billion dollars/year in the U.S. and to an average annual cost of 1089 euros per child/adolescent and 1543 euros per adult in Europe. The estimated annual costs in Northern America for asthma amounted to 14 billion dollars. Consequently, preventive strategies aimed at reducing the clinical severity of allergy are potentially able to reduce its costs. Among them, specific immunotherapy (SIT) joins to the preventive capacity the carryover effect once treatment is discontinued. A number of studies, mainly conducted in the US and Germany demonstrated a favourable cost-benefit balance. In the nineties, most surveys on patients with allergic rhinitis and asthma reported significant reductions of the direct and indirect costs in subjects treated with SIT compared to those treated with symptomatic drugs. This is fully confirmed in recent studies conducted in European countries: in Denmark the direct cost per patient/year of the standard care was more than halved following SIT; in Italy a study on Parietaria allergic patients demonstrated a significant difference in favor of SIT plus drug treatment for three years versus drug treatment alone, with a cost reduction starting from the 2nd year and increasing to 48% at the 3rd year, with a highly statistical significance which was maintained up to the 6th year, i.e. 3 years after stopping immunotherapy, corresponding to a net saving for each patient at the final evaluation of 623 euros per year; in France a cost/efficacy analysis comparing SIT and current symptomatic treatment in adults and children with dust mite and pollen allergy showed remarkable savings with SIT for both allergies in adults and children.

Abstract
BACKGROUND In sensitized subjects Hymenoptera stings may provoke the awakening of mediated systemic reactions of I type IgE, which can sometimes be serious. Considering the type of work performed activity and the high frequency of reported hymenoptera sting episodes, a sample of 206 Forestry Department agents was surveyed who worked outside urban areas in the Marche Region. OBJECTIVES The aim of the study was to analyse the prevalence of stings and their possible systemic reactions, as well as to evaluate the type of occupational risks involved. METHODS A total of 206 agents were examined and questioned about the number of stings suffered during work and about the kind of subsequent skin and systemic reactions; they were then classified according to the method proposed by H.L. Mueller. RESULTS 179 agents reported having suffered from hymenoptera stings and, of these, 53 subjects (29,6%) remembered that one episode at least occurred during work. Among 175 operators (98%), 4 had a regular reaction, with appearance of a generalized urticaria and uneasiness. In the remaining 4 agents (2%) there was a local extensive reaction, which was not associated with systemic reactions and they were all referred to allergological examination. 19 agents (10,6%) suffered more than 5 stings altogether, but none developed a systemic reaction. 87% of the subjects practised self-medication, 7% reported to the casualty department of the local hospital or to their own doctor, and 6% undertook no cure at all. CONCLUSIONS Epidemiological studies agree in recognizing that, in the general population, the percentage of systemic reactions after one or more hymenoptera stings varies from 0,15% to 3,3%. In categories of workers occupationally at risk, the prevalence of systemic reactions varies from 4,5% to 26%. The prevalence of systemic reactions in Forestry Department agents was 2%, which is similar to the prevalence in the general population. Therefore, rather than occupational risk, there appeared to be a generic risk made more serious by working conditions for Forestry Department agents due to their possible exposure to hymenoptera stings. The occupational health physician needs to monitor these events, due to the fact that frequent exposure to stings, above all occurring within a short period of time (less than two months) favours an increase in the tendency to develop systemic reactions, with a more serious prognosis, especially when working in isolated conditions.

Abstract
The efficacy and safety of sublingual immunotherapy (SLIT) are currently supported by clinical trials, meta-analysis and post-marketing surveys. Practice parameters for clinical use of SLIT are proposed here by a panel of Italian specialists, with reference to evidence based criteria. Indications to SLIT include allergic rhinoconjunctivitis, asthma, and isolated conjunctivitis (strength of recommendation: grade A). As to severity of the disease, SLIT is indicated in moderate/severe intermittent rhinitis, persistent rhinitis and mild to moderate asthma (grade D). SLIT may be safely prescribed also in children aged three to five years (grade B), and its use in subjects aged more than 60 years is not prevented when the indications and contraindication are ascertained (grade D). The choice of the allergen to be employed for SLIT should be made in accordance with the combination of clinical history and results of skin prick tests (grade D). Polysensitisation, i.e. the occurrence of multiple positive response does not exclude SLIT, which may be done with the clinically most important allergens (grade D). As to practical administration, co-seasonal, pre co-seasonal, and continuous schedules are available, being the latter recommended for perennial allergens or for pollens with particularly prolonged pollination, such as Parietaria (grade D). For pollens with relatively short pollination, such as grasses and trees (cypress, birch, alder, hazelnut, olive) the pre co-seasonal and perennial schedules are preferred (grade C). The build-up phases suggested by manufacturers can be safely used (grade A), but they can be modified according to the patient's tolerance (grade C). A duration of SLIT of 3-5 years is recommended to ensure a long-lasting clinical effect after the treatment has been terminated (grade C).

Abstract
The content and relative variations of individual carotenoids during the leaflet development stages (I, II, III, A and P) of six species of Ceratozamia (Cycads) were investigated. There is an unusual, transitory and marked presence of six red stroma keto-carotenoids in the first development stages, while the thylakoidal carotenoids showed a low concentration during the same period. As no official A1cm1% coefficients were available, it was necessary to calculate these for the following stroma carotenoids: semi-beta-carotenone (major component), triphasiaxanthin, ceratoxanthin, ceratozamiaxanthin, kuesteriaxanthin and ceratoxanthone. The stroma keto-carotenoids, which reached the highest content in the first development stage (average of 78% of total carotenoids), were always present in the five species: C. fuscoviridis, C. robusta, C. spinosa, C. kuesteriana and C. hildae, but never in C. mexicana. From stage II, the stroma keto-carotenoids decreased and finally disappeared in the green adult leaflets. The thylakoidal carotenoids showed a minimum at stage III, and then increased to a maximum in the perennial leaflets. Among these, beta-carotene showed an anomalous and characteristic behaviour, being a minor component during leaflet development (from stage I to A). In stage P it was markedly exceeded not only by lutein but also by alpha-carotene, neoxanthin and violaxanthin, and in C. robusta also by lutein-5,6-epoxide. Additionally, the alpha/beta ratio in these species is unusual: it increased from 0.3-0.5 to 1.5-3.0 during leaflet development. Moreover, antheraxanthin amounts are very small, while zeaxanthin was present only in the evergreen leaflets of C. mexicana in small quantities. Lutein-5,6-epoxide represented more than 5% of thylakoidal carotenoids in the leaflets of all the species. A revision of the taxonomic rank of C. fuscoviridis is recommended.

Abstract
• Chloroplast microsatellites (cpSSR) were used to analyze the patterns of genetic variation within and among populations of the serpentine endemic, Alyssum bertolonii . • Thirty-five different chloroplast haplotypes were identified in 90 plants sampled from nine populations originating from the four disjunct northern-Italian serpentine regions where the species is found. • High levels of genetic diversity were found within each of the populations sampled. Analysis of Molecular Variance (AMOVA) showed high degrees of differentiation among both different populations of the same serpentine region and different regions (Φ ST = 0.622, Φ CT = 0.252, respectively). • The results indicated that: each population was established by few founders and then subsequently differentiated the existing chloroplast haplotypes; each population is a distinct genetic entity; and populations within the same serpentine region are more related than populations from different regions.

Abstract
The Ku70/80 heterodimer is the regulatory subunit of the DNA-dependent protein kinase (DNA-PK) and its DNA-binding activity mediates DNA double-strand breaks repair. Although Ku80 was recently proposed as a caretaker gene involved in the control of genome integrity, no data are available on Ku70/80 DNA-binding activity in human tumors. Heterodimer DNA-binding activity and protein expression were assayed by electrophoretic-mobility-shift-assay (EMSA) and Western blot analysis, in nuclear and cytoplasmic extracts from eight breast, seven bladder primary tumors and three metastatic nodes from breast cancers. Corresponding normal tissues of the same patients were used as controls. Ten out of 15 tumors showed nuclear Ku-binding activity 3-10 times higher than in the normal tissues, irrespective of bladder or breast origin. Conversely, in 5/15 primary tumors and in all the metastatic nodes analysed, nuclear Ku-activity was 1.5-4.5-fold lower than in the corresponding normal tissues. Cytoplasmic heterodimer activity significantly differed between tumor and normal tissues, displaying a 2-10-fold increase in neoplastic tissues. Three different patterns combining both Ku expression and activity with tumor characteristics were identified. In low aggressive breast tumors p70/p80 proteins were expressed in tumor but not in normal tissues. The heterodimer binding-activity matched the protein levels. In non-invasive bladder carcinomas no significant differences in protein expression between tumor and the corresponding normal tissues were found, however heterodimer binding-activity was increased in tumor samples. In breast and bladder tumors, at the advanced stage and in node metastases, the binding activity was strongly reduced in tumor biopsies, however no differences were demonstrated between normal and tumor protein levels. Our results suggest a different modulation of Ku70/80 DNA-binding activity in human neoplastic tissues, possibly related to tumor progression. Findings provide further data on tissue-specific protein expression and post-translational regulation of heterodimer activity.

Abstract
A new method for the determination of benzene at trace levels in air is presented. The method consists of the collection of air samples on adsorbent cartridges with simultaneous adsorption of pre-established amounts of D6-labeled internal standard. Desorption from the cartridge is performed by solid-phase microextraction (SPME) with analysis by gas chromatography/mass spectrometry (GC/MS) using an ion trap mass spectrometer. The influence of several parameters (type of SPME fiber, temperature, time, for example) was investigated, and good linearity in the range 10-400 ng of C6D6, with a coefficient of variance (CV) around 3-5%, was obtained. The method was tested by sampling air in a town center in Italy, and a benzene concentration of approximately 50 microg/m(3) was determined. The maximum limit recommended by the European Community is 10 microg/m(3).

Abstract
Radioactive iodine (131I and 123I) labelled methylene blue is used for the early diagnosis of melanoma metastases. We studied the iodination reaction of methylene blue (using "cold" iodine) in order to characterise the iodination product(s) as far as number and position of iodine atoms introduced on the aromatic ring(s) is concerned. The reaction was carried out under the same experimental conditions used for the radioactive one, that is in a large excess of methylene blue. The ionspray HPLC-MS analysis of the reaction mixture showed that the iodinated methylene blue was present only in a very small amount and the main iodinated product was a demethylated one, coming out from the iodination of an impurity azure B. We also studied the iodination reaction of azure B in order to better explain the reaction pathway. Commercial azure B contains impurities of methylene blue and all the possible demethylated derivatives. HPLC-MS analysis of the reaction mixture allowed a complete characterisation of the iodinated and bis-iodinated products.

Abstract
The Fenton reaction for the degradation of surfactants has been investigated and partial degradation products have been identified and characterized by mass spectrometry for the case of lauryl sulphate. The polar soluble products were investigated by liquid chromatography/mass spectrometry (LC/MS) with electrospray ionization (ESI), and the volatile products leaving the mixture during the reaction were trapped by means of solid-phase microextraction (SPME) and investigated by gas chromatography/mass spectrometry (GC/MS) with electron and chemical ionization. The oxidation leads to the formation of products with hydroxyl and epoxide groups due to insertion of oxygen atoms or to aldehydes derived from the loss of the hydrophilic sulphate group. The extent of mineralization is dependent on peroxide and iron concentrations. Copyright 1999 John Wiley & Sons, Ltd.

Abstract
The monitoring of air pollution requires simple, rapid and sensitive sampling and analytical techniques with minimal sample manipulation that are usable for routine analyses. In our laboratories we have developed a method for the analysis of air samples collected by adsorbent cartridges based on solid phase microextraction (SPME) coupled to gas chromatography/mass spectrometry. We investigated the influence of some variables (time and temperature) using toluene as analyte (one of the most common air pollutants) and toluene-d(8) on the SPME extraction, and the sensitivity (LOQ) of the method. We then tested the method on an air sample collected in an industrial area and carried out characterisation of the volatile organic compounds present.

Abstract
The loss of IL-2 production is the main defect accounting for age-related immunodeficiencies. We have investigated the molecular mechanisms involved in the decrease of IL-2 production in CD4+ T cells from aging mice. Our results demonstrate that the stability of IL-2 mRNA increases in T cells from young mice, whereas it declines in T cells from old mice with the time of stimulation, suggesting the existence of different mechanisms of post-transcriptional regulation in young and old mice. We found that the IL-2 mRNA level in T cells from young but not from old mice increased up to 6- to 10-fold by addition of cycloheximide (CHX) while the stability of IL-2 mRNA is not affected. We then looked for IL-2 inducible inhibitory factors in T cells from young and old mice and demonstrated the presence of Nil-2-a, a zinc finger protein which negatively controls IL-2 gene transcription in human cells. This protein could be detected in T cells from both young and old mice, yet, in the presence of CHX, its binding activity was reduced by 75% in T cells from young but not from old mice. These findings show that Nil-2-a accounts for the negative control of IL-2 production in the mouse and explain the reduced IL-2 production in aging.

Abstract
CD4+ cells from young (3 months) and old (19 months) mice were stimulated by plate-bound anti-CD3 monoclonal antibody (mAb) alone or also by soluble anti-CD28 mAb. Supernatants were analysed by enzyme-linked immunosorbent assay (ELISA) to determine cytokine concentrations. Total RNA was extracted from cells, reverse transcribed and the cDNA amplified by polymerase chain reaction (PCR) to evaluate the amount of specific mRNA. The results indicate that anti-CD3 alone is not sufficient to induce interleukin-2 (IL-2) production in CD4+ cells from both young and old mice. However, anti-CD28, together with anti-CD3 mAb, induces a much higher production of IL-2 in CD4+ cells from young as compared with old mice. Conversely, interferon-gamma (IFN-gamma) production is also induced by anti-CD3 alone and is higher in CD4+ cells from old as compared with young mice. Upon addition of anti-CD28 mAb, IFN-gamma production increases in both groups, but it remains much higher in old than in young mice. Also the production of IL-4 and IL-10 is induced by anti-CD3 mAb but it is increased by the addition of anti-CD28 mAb. CD4+ cells from old mice produce more IL-4 and IL-10 as compared with cells from young mice. The amounts of cytokine specific mRNA in CD4+ cells from young and old mice parallel the cytokine levels in culture supernatants. Results on the mRNA turnover indicate that when CD4+ cells are stimulated by anti-CD3 or costimulated also by anti-CD28 mAb, the IFN-gamma, IL-4 and IL-10 specific mRNAs are more stable in old than in young mice, suggesting that mRNA stability has a relevant role in the different patterns of cytokine production.

Abstract
Previous studies on DNA repair in ageing have demonstrated increased frequencies of single and double strand breaks in lymphocytes from elderly subjects and, as a consequence, decreased efficiency in DNA replication. We have investigated the relationship between cell proliferation and the nuclear expression of ku protein in a human population of 43 subjects of different ages. Ku is an heterodimeric protein composed of two subunits of 70 and 80 kDa, which is involved in the early steps of DNA damage recognition. In the present study, PBL from subjects of different ages were PHA-activated to evaluate the stimulation index and the production of Th1- and Th2-type cytokines. Moreover, nuclear extracts were obtained from activated lymphocytes to evaluate by a gel retardation assay the presence and the functional activity of the heterodimer ku 70/80. Our results indicate that ageing affects the mitotic responsiveness and cytokine production to a significant extent, but only marginally the expression of ku 70/80. These findings suggest that the age-related impairment in DNA repair mechanisms are only in part related to the reduced expression of ku protein able to recognize DNA damage.
