Abstract
We report the results of a search for neutrinoless double-beta decay in a 9.8 kg yr exposure of (130)Te using a bolometric detector array, CUORE-0. The characteristic detector energy resolution and background level in the region of interest are 5.1±0.3 keV FWHM and 0.058±0.004(stat)±0.002(syst)counts/(keV kg yr), respectively. The median 90% C.L. lower-limit half-life sensitivity of the experiment is 2.9×10(24) yr and surpasses the sensitivity of previous searches. We find no evidence for neutrinoless double-beta decay of (130)Te and place a Bayesian lower bound on the decay half-life, T(1/2)(0ν)>2.7×10(24) yr at 90% C.L. Combining CUORE-0 data with the 19.75 kg yr exposure of (130)Te from the Cuoricino experiment we obtain T(1/2)(0ν)>4.0×10(24) yr at 90% C.L. (Bayesian), the most stringent limit to date on this half-life. Using a range of nuclear matrix element estimates we interpret this as a limit on the effective Majorana neutrino mass, m(ββ)<270-760 meV.

Abstract
Next-generation experiments searching for neutrinoless double-beta decay must be sensitive to a Majorana neutrino mass as low as 10[Formula: see text]. CUORE , an array of 988 TeO[Formula: see text] bolometers being commissioned at Laboratori Nazionali del Gran Sasso, features an expected sensitivity of 50-130[Formula: see text] at 90 % C.L. The background is expected to be dominated by [Formula: see text] radioactivity, and can be in principle removed by detecting the small amount of Cherenkov light emitted by the [Formula: see text] signal. The Cryogenic wide-Area Light Detectors with Excellent Resolution project aims at developing a small prototype experiment consisting of TeO[Formula: see text] bolometers coupled to high-sensitivity light detectors based on kinetic inductance detectors. The R&D is focused on the light detectors in view of the implementation in a next-generation neutrinoless double-beta decay experiment.

Abstract
BACKGROUND In recent years, the efficacy of probiotics has received considerable attention in the treatment for irritable bowel syndrome (IBS). In this regard, a symbiotic mixture (Probinul(®)) has shown beneficial effects. The aim of this study was to extend the previously published 4-week randomized, double-blinded, placebo-controlled study of this symbiotic mixture. METHODS This is an open-label prospective, partially controlled, 6-month extension period pilot study in which patients continued to receive the symbiotic mixture (Group 1) or were switched from placebo to symbiotic mixture (Group 2) using cyclic administration (last 2 weeks/month). The primary endpoints were the overall satisfactory relief of bloating and flatulence (assessed as proportions of responders). The secondary endpoints were evaluation of the symptom severity scores (bloating, flatulence, pain and urgency) and bowel function scores (frequency, consistency and incomplete evacuation). RESULTS Twenty-six IBS patients completed the 6-month extension period (13 patients in Group 1 and 13 patients in Group 2). In the per-protocol analysis, the proportions of responders across time were not significantly different in the groups but in Group 2, there was an increased percentage of responders for flatulence (p = 0.07). In addition, the score of flatulence was reduced significantly during the 6-month treatment period in Group 2 (p < 0.05), while no other significant differences were detected. CONCLUSIONS Treatment with this symbiotic mixture was associated with persistence of relief from flatulence or new reduction in flatulence in the present 6-month long extension study. These results need to be more comprehensively assessed in large, long-term, randomized, placebo-controlled studies.

Abstract
Literature reports describe kiwi fruit as a food with significant effects on human health, including anti-oxidant and anti-inflammatory activity. Fresh fruit or raw kiwi fruit extracts have been used so far to investigate these effects, but the molecule(s) responsible for these health-promoting activities have not yet been identified. Kissper is a kiwi fruit peptide displaying pore-forming activity in synthetic lipid bilayers, the composition of which is similar to that found in intestinal cells. The objective of this study was to investigate the kissper influence on intestinal inflammation using cultured cells and ex-vivo tissues from healthy subjects and Crohn's disease (CD) patients. The anti-oxidant and anti-inflammatory properties of kissper were tested on Caco-2 cells and on the colonic mucosa from 23 patients with CD, by challenging with the lipopolysaccharide from Escherichia coli (EC-LPS) and monitoring the appropriate markers by Western blot and immunofluorescence. EC-LPS challenge determined an increase in the intracellular concentration of calcium and reactive oxygen species (ROS). The peptide kissper was highly effective in preventing the increase of LPS-induced ROS levels in both the Caco-2 cells and CD colonic mucosa. Moreover, it controls the calcium increase, p65-nuclear factor (NF)-kB induction and transglutaminase 2 (TG2) activation inflammatory response in Caco-2 cells and CD colonic mucosa. Kissper efficiently counteracts the oxidative stress and inflammatory response in valuable model systems consisting of intestinal cells and CD colonic mucosa. This study reports the first evidence supporting a possible correlation between some beneficial effects of kiwi fruit and a specific protein molecule rather than generic nutrients.

Abstract
Background. Symptoms of celiac disease negatively impact social activities and emotional state. Aim was to investigate the prevalence of altered eating behaviour in celiac patients. Methods. Celiac patients and controls completed a dietary interview and the Binge Eating Staircases, Eating Disorder Inventory (EDI-2), Eating Attitudes Test, Zung Self-Rating Depression Scale, State Trait Anxiety Inventory Forma Y (STAI-Y1 and STAI-Y2), and Symptom Check List (SCL-90). Results. One hundred celiac adults and 100 controls were not statistically different for gender, age, and physical activity. STAI-Y1 and STAI-Y2, Somatization, Interpersonal, Sensitivity, and Anxiety scores of the SLC-90 were higher in CD patients than controls. EDI-2 was different in pulse thinness, social insecurity, perfectionism, inadequacy, ascetisms, and interpersonal diffidence between CD and HC women, whilst only in interceptive awareness between CD and HC men. A higher EAT-26 score was associated with the CD group dependently with gastrointestinal symptoms. The EAT26 demonstrated association between indices of diet-related disorders in both CD and the feminine gender after controlling for anxiety and depression. Conclusion. CD itself and not gastrointestinal related symptoms or psychological factors may contribute pathological eating behavior in celiac adults. Eating disorders appear to be more frequent in young celiac women than in CD men and in HC.

Abstract
1. Budesonide is a glucocorticosteroid with a local anti-inflammatory effect. Coeliac disease is an immune-mediated disease caused by gluten ingestion in intolerant patients. The aim of the present study was to investigate the efficacy of budesonide in malabsorptive coeliac patients and its effect in an in vitro gliadin challenge. 2. Twenty coeliac patients with malabsorption were enrolled in the present study and were randomly assigned to one of two 4 week treatments: (i) a gluten-free diet alone; or (ii) a gluten-free diet plus 6 mg budesonide daily. At the end of 4 weeks treatment, all patients underwent clinical evaluation, laboratory tests and self-evaluation of well-being using a visual analogue scale. Intestinal biopsies from five coeliac patients (selected randomly) and four non-coeliac disease controls who underwent upper endoscopy for intestinal bleeding were challenged with gliadin (0.5 mg/mL) and budesonide (10-30 microg/mL) for 3 and 24 h. Biopsies were tested by immunohistochemistry and immunofluorescence for known markers of inflammation. 3. Treatment of patients with 6 mg budesonide daily for 4 weeks resulted in increased bodyweight, a decreased number of evacuations and decreased stool weight compared with patients on a gluten-free diet alone for 4 weeks. Well-being scores were higher in patients treated with both a gluten-free diet and budesonide compared with those receiving a gluten-free diet alone. 4. In vitro studies showed that budesonide reduced epithelial tyrosine phosphorylation and expression of histocompatibility leucocyte antigen complex DR (HLA-DR) elicited by gliadin-derived peptides. In addition, the expression of cyclo-oxygenase (COX)-2 and intercellular adhesion molecule (ICAM)-1 in the lamina propria was reduced in patients treated with both gliadin and budesonide compared with patients treated with gliadin alone. Budesonide alone decreased HLA-DR in crypt enterocytes, as well as ICAM-1 and COX-2 expression in the lamina propria of biopsy specimen of coeliac patients. Budesonide had no effect in control samples. 5. In conclusion, the results of the present study indicate that budesonide shows efficacy in the treatment of symptoms in adult coeliac patients with overt malabsorption. The mechanism underlying the effects of budesonide in reducing symptoms was elucidated by in vitro studies involving a gliadin challenge.

Abstract
OBJECTIVE Coeliac disease (CD) is associated with immune-mediated skin diseases such as dermatitis herpetiformis and others. The objective of the study was to investigate the relation of body mass index (BMI), as an index of absorptive status, with the prevalence of skin diseases in adults with untreated CD. METHODS Anthropometry, gastro-intestinal symptoms, nutritional indices and immune-mediated skin diseases (dermatitis herpetiformis, psoriasis, aphthosis and alopecia) at diagnosis were analysed. RESULTS 223 men and 924 women with untreated CD (aged 20-60 years) were included, the commonest skin disease was dermatitis herpetiformis (18.4 and 6.9%, respectively), the rarest one was alopecia (1.8 and 2.1%). The BMI was positively associated with male gender, age at diagnosis and nutritional indices, negatively with diarrhoea and dyspepsia (p < 0.001). A BMI difference of 3.5 (1 standard deviation) was related to an excess prevalence of dermatitis herpetiformis (odds ratio, OR = 1.46, 95% confidence interval, CI = 1.23-1.72) and of psoriasis (OR = 1.40, 95% CI = 1.10-1.79) but not of other immunological disorders. Findings were similar in analyses by gender or age group and controlled for gender and age. The relation of BMI to dermatitis herpetiformis was linear over the whole BMI range, also excluding overweight patients. The relation of BMI to psoriasis was flat for low-to-normal BMI and explained only by overweight patients. CONCLUSION In CD at diagnosis, the BMI is positively related to the prevalence of dermatitis herpetiformis and psoriasis, not to that of other immune-mediated skin diseases.

Abstract
Airborne trace elements are implicated in the etio-pathogenesis of a large number of pulmonary diseases. The aim of this study was to evaluate the reliability and effectiveness of direct determination of Cd, Cr, Cu, Fe, Mn, Ni, Pb, V, and Zn concentrations in bronchoalveolar lavage (BAL) samples from patients with sarcoidosis, idiopathic pulmonary fibrosis, and Langerhans cell histiocytosis and healthy (smoking and non-smoking) controls. A total of 44 individuals were recruited among sarcoidosis, idiopathic pulmonary fibrosis, and Langerhans cell histiocytosis patients and healthy (smoking and non-smoking) controls. Average Mn concentrations in BAL from patients were 45% lower than in controls (p < 0.01) and remarkable decreases in average concentrations of Cr, Ni and Zn were also found in BAL from patients with idiopathic pulmonary fibrosis and Langerhans cell histiocytosis. As these diseases are characterized by the enhanced activation of certain immunomodulatory cells and by generation of free radicals, the depressed Mn, Zn, Cr and Ni concentrations in BAL from patients may be due to oxidative stress. These preliminary results indicate that assessment of the elemental composition of BAL is a promising approach to study the pathogenesis of diffuse lung diseases and Langerhans cell histiocytosis.

Abstract
BACKGROUND Fatigue is common in celiac disease. L-Carnitine blood levels are low in untreated celiac disease. L-Carnitine therapy was shown to improve muscular fatigue in several diseases. AIM To evaluate the effect of L-carnitine treatment in fatigue in adult celiac patients. METHODS Randomised double-blind versus placebo parallel study. Thirty celiac disease patients received 2 g daily, 180 days (L-carnitine group) and 30 were assigned to the placebo group (P group). The patients underwent clinical investigation and questionnaires (Scott-Huskisson Visual Analogue Scale for Asthenia, Verbal Scale for Asthenia, Zung Depression Scale, SF-36 Health Status Survey, EuroQoL). OCTN2 levels, the specific carnitine transporter, were detected in intestinal tissue. RESULTS Fatigue measured by Scott-Huskisson Visual Analogue Scale for Asthenia was significantly reduced in the L-carnitine group compared with the placebo group (p=0.0021). OCTN2 was decreased in celiac patients when compared to normal subjects (-134.67% in jejunum), and increased after diet in both celiac disease treatments. The other scales used did not show any significant difference between the two celiac disease treatment groups. CONCLUSION L-Carnitine therapy is safe and effective in ameliorating fatigue in celiac disease. Since L-carnitine is involved in muscle energy production its decreased absorption due to OCTN2 reduction might explain muscular symptoms in celiac disease patients. The diet-induced OCTN2 increase, improving carnitine absorption, might explain the L-carnitine treatment efficacy.

Abstract
BACKGROUND Celiac disease (CD) is a chronic intolerance to gluten, which induces intestinal mucosal lesions in genetically predisposed individuals. Transabdominal bowel sonography (TABS) is a safe and noninvasive procedure that allows to detect intestinal abnormalities in many conditions, but actually is not routinely part of the diagnostic management of CD. AIM To evaluate the diagnostic accuracy of TABS in CD patients. PATIENTS AND METHODS Fifty CD patients and 50 dyspeptic subjects (control group) underwent TABS. The presence of fluid-distended small bowel loops with thickened valvulae conniventes and increased peristalsis was considered a TABS sign of CD. All clinical, biochemical, and TABS features were assessed at the diagnosis and revaluated after 1 year of gluten-free diet. RESULTS TABS signs were present in 66% of CD patients. Sensitivity, specificity, positive and negative predictive value were 66%, 96%, 94%, and 74%, respectively. TABS findings were recorded in 82% of patients with endoscopical markers of CD, in 87.5% of symptomatic patients, and in 61% of patients without symptoms. After 1 year of gluten-free diet TABS was still abnormal in 20% patients, with no correlation with laboratory tests e/o symptoms. CONCLUSIONS Patients with CD frequently present TABS signs of the disease and operators performing sonography every day have to consider the possibility to suggest CD diagnosis and aTTG determination in these subjects.

Abstract
We report the present results of CUORICINO, a search for neutrinoless double-beta (0nu betabeta) decay of 130Te. The detector is an array of 62 TeO2 bolometers with a total active mass of 40.7 kg. The array is cooled by a dilution refrigerator shielded from environmental radioactivity and energetic neutrons, operated at approximately 8 mK in the Gran Sasso Underground Laboratory. No evidence for (0nu betabeta) decay was found and a new lower limit, T(1/2)(0nu) > or = 1.8 x 10(24) yr (90% C.L.) is set, corresponding to [m(nu)] < or = 0.2 to 1.1 eV, depending on the theoretical nuclear matrix elements used in the analysis.

Abstract
The Cu-ATPase ATP7A (MNK) is localized in the trans-Golgi network (TGN) and relocalizes in the plasma membrane via vesicle-mediated traffic following exposure of the cells to high concentrations of copper. Rab proteins are organelle-specific GTPases, markers of different endosomal compartments; their role has been recently reviewed (Trends Cell Biol. 11(2001) 487). In this article we analyze the endosomal pathway of trafficking of the MNK protein in stably transfected clones of CHO cells, expressing chimeric Rab5-myc or Rab7-myc proteins, markers of early or late endosome compartments, respectively. We demonstrate by immunofluorescence and confocal and electron microscopy techniques that the increase in the concentration of copper in the medium (189 microM) rapidly induces a redistribution of the MNK protein from early sorting endosomes, positive for Rab5-myc protein, to late endosomes, containing the Rab7-myc protein. Cell fractionation experiments confirm these results; i.e., the MNK protein is recruited to the endosomal fraction on copper stimulation and colocalizes with Rab5 and Rab7 proteins. These findings allow the first characterization of the vesicles involved in the intracellular routing of the MNK protein from the TGN to the plasma membrane, a key mechanism allowing appropriate efflux of copper in cells grown in high concentrations of the metal.

Abstract
Transposition plays a role in the epidemiology and pathogenesis of Neisseria meningitidis. Insertion sequences are involved in reversible capsulation and insertional inactivation of virulence genes encoding outer membrane proteins. In this study, we have investigated and identified one way in which transposon IS1106 controls its own activity. We have characterized a naturally occurring protein (Tip) that inhibits the transposase. The inhibitor protein is a truncated version of the IS1106 transposase lacking the NH(2)-terminal DNA binding sequence, and it regulates transposition by competing with the transposase for binding to the outside ends of IS1106, as shown by gel shift and in vitro transposition assays. IS1106Tip mRNA is variably expressed among serogroup B meningococcal clinical isolates, and it is absent in most collection strains belonging to hypervirulent lineages.

Abstract
PRA1 (prenylated Rab acceptor) is a general regulator of Rab proteins, while RILP (Rab interacting lysosomal protein) is a specific effector for Rab7. It has been shown that PRA1 interacts with Rab proteins and with VAMP2. Therefore PRA1 is probably an important factor for membrane traffic, linking together the function of Rab proteins and SNAREs. RILP has a key role in the control of transport to degradative compartments together with Rab7 and probably links Rab7 function to the cytoskeleton. Here we have studied by Northern blot the expression of the two genes in several different human tissues. The 0.8-kb mRNA for human PRA1 is ubiquitously expressed, while the two mRNAs for RILP are differentially expressed. In addition, we have assigned the human PRA1 gene to chromosome 19q13.13-q13.2 and the human RILP gene to chromosome 17p13.3.

Abstract
Phase variation through slippage-like mechanisms involving homopolymeric tracts depends in part on the absence of Dam-methylase in several pathogenic isolates of Neisseria meningitidis. In Dam-defective strains drg (dam-replacing gene), flanked by pseudo-transposable small repeated elements (SREs), replaced dam. We demonstrate that drg encodes a restriction endonuclease (NmeBII) that cleaves 5'-GmeATC-3'. drg is also present in 50% of Neisseria lactamica strains, but in most of them it is inactive because of the absence of an SRE-providing promoter. This is associated with the presence of GATmeC, suggesting an alternative restriction-modification system (RM) specific for 5'-GATC-3', similar to Sau3AI-RM of Staphylococcus aureus 3A, Lactococcus lactis KR2 and Listeria monocytogenes.

Abstract
The small GTPases Rab4, Rab5 and Rab7 are endosomal proteins which play important roles in the regulation of various stages of endosomal trafficking. Rab4 and Rab5 have both been localized to early endosomes and have been shown to control recycling and endosomal fusion, respectively. Rab7, a marker of the late endosomal compartment, is involved in the regulation of the late endocytic pathway. Here, we compare the role of Rab4, Rab5 and Rab7 in early and late endosomal trafficking in HeLa cells monitoring ligand uptake, recycling and degradation. Expression of the Rab4 dominant negative mutant (Rab4AS22N) leads to a significant reduction in both recycling and degradation while, as expected, Rab7 mutants exclusively affect epidermal growth factor (EGF) and low density lipoprotein degradation. As also expected, expression of the dominant negative Rab5 mutant perturbs internalization kinetics and affects both recycling and degradation. Expression of Rab4WT and dominant positive mutant (Rab4AQ67L) changes dramatically the morphology of the transferrin compartment leading to the formation of membrane tubules. These transferrin positive tubules display swellings (varicosities) some of which are positive for early endosomal antigen-1 and contain EGF. We propose that the Rab4GTPase is important for the function of the early sorting endosomal compartment, affecting trafficking along both recycling and degradative pathways.
