    Notes: As part of a cross-sectional study on cholelithiasis, 1533 out of 1840 residents in Loiano/Monghidoro, a rural area in Northern Italy (792 men, 741 women, age range 28–80 years), agreed to be further evaluated in relation to their Helicobacter pylori status.〈section xml:id="abs1-2"〉〈title type="main"〉Methods:Each participant performed a 13C-urea breath test (13C-UBT) and provided information on sociodemographic, lifestyle and clinical characteristics.〈section xml:id="abs1-3"〉〈title type="main"〉Results:The 13C-UBT was positive in 1041 subjects (67.9%; men: 69%; women: 67%) and was positively associated with increasing age (P 〈 0.001), alcohol consumption (P 〈 0.01), a higher number of siblings (P 〈 0.001) and a personal history of peptic ulcer (P 〈 0.01), but inversely with a nonmanual occupation (P 〈 0.001). Overall, H. pylori infection was unrelated to smoking, house pets, and a family history of gastroduodenal diseases. The prevalence of H. pylori infection was 72% in subjects reporting one or more dyspeptic symptoms and 65% among asymptomatic participants (P 〈 0.001); a multivariate analysis showed that only epigastric pain was significantly, although weakly, associated with 13C-UBT positivity.〈section xml:id="abs1-4"〉〈title type="main"〉Conclusions:This large population-based study showed a prevalence of H. pylori infection higher than that reported by serologic surveys in urban areas. Current H. pylori infection was strongly associated with indicators of lower socioeconomic status, alcohol consumption and increasing age. A role of H. pylori infection in determining epigastric pain was suggested.

    Notes: To compare, in a randomized controlled trial, the efficacy and tolerability of two 1-week triple therapies for Helicobacter pylori eradication.〈section xml:id="abs1-2"〉〈title type="main"〉Methods:One hundred and thirty-four consecutive patients with non-ulcer dyspepsia and H. pylori infection were randomized to receive lansoprazole 30 mg once daily, clarithromycin 250 mg twice daily, and metronidazole 500 mg twice daily (LCM group), or lansoprazole 30 mg twice daily, clarithromycin 500 mg twice daily, and amoxicillin 1000 mg twice daily (LCA group). H. pylori status was assessed by rapid urease test, histology and 13C-urea breath test before and after therapy.〈section xml:id="abs1-3"〉〈title type="main"〉Results:At 3 months, H. pylori eradication (intention- to-treat/per protocol analysis) was 92.4%/93.8% in the LCM group and 83.1%/85.7% in the LCA group (P=N.S.). Side-effects were more frequently reported in the LCA group (37.9%) than in the LCM group (19.7%) (P 〈 0.05).〈section xml:id="abs1-4"〉〈title type="main"〉Conclusions:In this open, randomized controlled trial, eradication of H. pylori by low-dose lansoprazole and clarithromycin plus metronidazole was higher with significantly less side-effects than by full-dose lansoprazole and clarithromycin plus amoxicillin. This finding may be related to the stronger synergism of clarithromycin plus metronidazole, even at lower doses, than of clarithromycin plus amoxicillin. Considering the lower cost as well, LCM should be preferred to LCA in the eradication of H. pylori.

    Notes: Background:  Several in vitro studies demonstrate that corticosteroids and long-acting β2 agonists may have a complementary and synergistic mode of action on the inflammatory processes in asthma.Methods:  Sputum was induced in 20 mild to moderate asthmatic patients and the induced sputum cells (ISC) were cultured with beclomethasone dipropionate (BDP) 10−7 M, salbutamol 10−8 M and formoterol 10−8 M either alone or in combination, BDP plus salbutamol and BDP plus formoterol, for 24 h. We measured the levels of growth macrophages-colony stimulating factor (GM-CSF), released on activation normal T cells expressed and activated (RANTES) and interleukin-8 (IL-8), in the supernatant of stimulated cells by ELISA. Furthermore, we assessed nuclear translocation of glucocorticoid receptor (GR) and the expression of β2 receptor in ISC by immunofluorescence and RT-PCR, respectively.Results:  The release of GM-CSF, RANTES and IL-8 in ISC was significantly reduced by BDP plus salbutamol or formoterol as compared with either drug alone (P 〈 0.0001). β2 receptor expression was increased after 30 min of incubation with BDP and continued to increase over a time period of 4 h (P 〈 0.0001). Furthermore after 30 min of incubation, nuclear translocation of GR was greater with BDP plus salbutamol or formoterol than with any of the drugs alone (P 〈 0.0001).Conclusion:  The present ex vivo study demonstrates a complementary mode of action between BDP and salbutamol or formoterol leading to an enhanced anti-inflammatory activity.

    Notes: Abstract A mid-infrared (8–22 μm) camera, equipped with a Hughes hybrid bulk Si:As array detector of 10×64 pixels was developed for the 1.5 m Italian Infrared Telescope (TIRGO). The instrument was used for narrow- band 8–14 μm high-background astronomical observations. Here we present a short description of the camera, including its fast readout electronics and its optical design. When used at TIRGO, the camera has a pixel scale of 1.23 arcsec/pix. From the observations of infrared standard stars we derived a noise equivalent flux density (NEFD) that, for all the filters, is in the range 0.5–0.7 Jy×arcsec-2×min-1/2 and a point spread function (PSF) of the order of 3 arcsec(FWHM). Mosaics of the extended sources Mars at 8.8, 9.8, and 12.5 μm, and of the star forming region Orion BN-KL Nebula at 12.5 μm, are shown. The camera performances are also illustrated on the basis of the image of the post-AGB source CRL618.

    Description / Table of Contents: Creep Strength and High Temperature Damage of Incoloy 800 HT after Solution Treatment and High Temperature AgeingIn the present work the influence of heat, treatment, especially for high temperature ageing, on the creep strength and the intercrystalline creep damage of the iron base alloy Incoloy 800 HT(X10 NiCrAlTi 32 20 HT) is examined. For this purpose the properties and the damage behaviour, particulary the magnitude of damage, of the preaged materials at two test temperatures are compared to the solution treated material after creep failure. The results of metallographic investigation (optical, SEM and TEM) were used to study the influence of long therm ageing on the damage and the microstruture. The damage is quantified by using a damage parameter which is derived from the creep crack density and the length.
    Notes: In der vorliegenden Arbeit wird der Einfluß der Wärmebehandlung, insbesondere der einer langzeitigen Hochtemperaturauslagerung, auf die Zeitstandfestigkeit und die interkristalline Schädigung der Eisenbasislegierung Incoloy 800 HT (X10 NiCrAlTi 32 20 HT) untersucht. Dabei werden zum einen der lösungsgeglühte Zu-stand und zum anderen langzeitig, bis zu einer Gesamtdauer von 3000h, überalterte Werkstoffzustände bei zwei Versuchstemperaturen im Zeitstandexperiment miteinander verglichen. Die Ergebnisse metallographischer und elektronenmikroskopischer Untersuchungen zur Beeinflussung der auftretenden interkristallinen Schädigung durch die Langzeitauslagerung werden vorgestellt und mit einem quantitativen Schädigungsparameter beschrieben. Die auftretende Schädigung im überalterten und löungsgeglühten Werkstoff nach Zeitstandbeanspruchung werden miteinander verglichen.

    Description / Table of Contents: Evolution of the Microstructure in Alloy 800HT under High Temperature Creep LoadIn the present work the microstructural evolution under isothermal and high temperature creep conditions is studied for the iron-base-alloy Incoloy Alloy 800HT (X10 NiCrAlTi 32 20 HT) at temperatures of 800° and 900° and stresses of 70 MPa and 45 MPa resp. To describe the microstructure changes under creep stress loading and constant test temperature the dislocation density, particle size and mean planer interparticle spacing where investigated using transmission electron microscopy. The results of the dislocation density and particle morphology measurements are compared and discussed in the context of creep deformation, heat treatment conditions and creep behaviour.
    Notes: In der vorliegenden Arbeit wird die Entwicklung der Mikrostruktur, gekennzeichnet durch die Merkmale Versetzungsdichte, Partikelvolumenanteil und -abstand bei Hochtemperaturkriechbeanspruchung, der Eisenbasislegierung Incoloy Alloy 800HT (X10 NiCrAlTi 32 20 HT) untersucht. Zur Beschreibung der Evolution der Mikrostruktur in Abhängigkeit von Temperatur und Kriechverformung werden isotherme Wärmebehandlungen und Kriechexperimente bei 800° / 800° und 70MPa sowie 900° / 900° und 45MPa durchgeführt. Die Untersuchung der sich durch die Beanspruchungen einstellenden Gefügeänderugen erfolgt mit Methoden der Elektronenmikroskopie, vornehmlich im Transmissionselektronenmikroskop. Eine detaillierte Auswertung der sich ergebenden Versetzungsdichten und Größen der ausgeschiedenen Karbide wird mit den Zeitstandkenngrößen in Beziehung gesetzt, analysiert und diskutiert.
