Abstract
An atomic clock based on x-ray fluorescence yields has been used to estimate the mean characteristic time for fusion followed by fission in reactions 238U + 64Ni at 6.6 MeV/A. Inner shell vacancies are created during the collisions in the electronic structure of the possibly formed Z=120 compound nuclei. The filling of these vacancies accompanied by a x-ray emission with energies characteristic of Z=120 can take place only if the atomic transitions occur before nuclear fission. Therefore, the x-ray yield characteristic of the united atom with 120 protons is strongly related to the fission time and to the vacancy lifetimes. K x rays from the element with Z=120 have been unambiguously identified from a coupled analysis of the involved nuclear reaction mechanisms and of the measured photon spectra. A minimum mean fission time τ(f)=2.5×10(-18) s has been deduced for Z=120 from the measured x-ray multiplicity.

Abstract
AIM Liraglutide is a GLP-1 analogue introduced in Italy in 2010; its efficacy and safety have been tested within the comprehensive "LEAD program". The aim of this paper was to evaluate whether and to what extent routine practice outcomes are consistent with research findings. METHODS One diabetes outpatient clinic reviewed data of patients receiving incretin-based therapies. Differences in characteristics of patients treated with liraglutide, exenatide, or DPP-IV inhibitors were evaluated. The subgroups of patients treated with liraglutide, exenatide or DPP-IV inhibitors (sitagliptin, vildagliptin, saxagliptin) and followed for at least eight months were analyzed longitudinally. Hierarchical linear models for repeated measurements were applied to assess trends over time. RESULTS Incretin-based treatments were prescribed to 312 patients (liraglutide: 130, exe-natide: 72, DPP-IV inhibitors: 110). Diabetes duration, HbA1c levels, and BMI were substantially higher in exenatide and liraglutide groups than in the DPP-IV inhibitors group. Liraglutide was often administered in combination with metformin alone, while exenatide was often added to two or more drugs. Overall, 20 (15.4%) liraglutide interruptions were recorded, especially due to nausea. Treatment drop out rate was higher in exenatide and DPP-IV inhibitors groups (in exenatide mostly for gastrointestinal side effects, in DPP-IV for inefficacy). After eight months, overall levels of HbA1c were reduced from 8.1±1.1 to 7.1±0.8 (P<0.0001) with liraglutide. Furthermore, fasting blood glucose was reduced by 37.9±6.2 mg/dL (P<0.0001), body weight by 4.1±0.5 kg (P<0.0001), systolic blood pressure by 8.9±2.7 mmHg (P<0.001), total cholesterol by 8.8±4.1 mg/dL (P=0.04), and triglycerides by 24.4±14.6 mg/dL (P=0.07). Patients who had their therapy replaced at baseline from exenatide or DPP-IV had a further reduction in HbA1c, FBG and body weight. CONCLUSION Liraglutide is penetrating diabetes care with results strictly mimicking the promising beneficial effects found in the LEAD program.

Abstract
The gravitational-wave (GW) sky may include nearby pointlike sources as well as stochastic backgrounds. We perform two directional searches for persistent GWs using data from the LIGO S5 science run: one optimized for pointlike sources and one for arbitrary extended sources. Finding no evidence to support the detection of GWs, we present 90% confidence level (C.L.) upper-limit maps of GW strain power with typical values between 2-20×10(-50) strain(2) Hz(-1) and 5-35×10(-49) strain(2) Hz(-1) sr(-1) for pointlike and extended sources, respectively. The latter result is the first of its kind. We also set 90% C.L. limits on the narrow-band root-mean-square GW strain from interesting targets including Sco X-1, SN 1987A and the Galactic center as low as ≈7×10(-25) in the most sensitive frequency range near 160 Hz.

Abstract
We report an application of Kalman filtering to the inverted pendulum (IP) of the Virgo gravitational wave interferometer. Using subspace method system identification techniques, we calculated a linear mechanical model of Virgo IP from experimental transfer functions. We then developed a Kalman filter, based on the obtained state space representation, that estimates from open loop time domain data, the state variables of the system. This allows the observation (and eventually control) of every resonance mode of the IP mechanical structure independently.

Abstract
In-vacuum Faraday isolators (FIs) are used in gravitational wave interferometers to prevent the disturbance caused by light reflected back to the input port from the interferometer itself. The efficiency of the optical isolation is becoming more critical with the increase of laser input power. An in-vacuum FI, used in a gravitational wave experiment (Virgo), has a 20 mm clear aperture and is illuminated by an almost 20 W incoming beam, having a diameter of about 5 mm. When going in vacuum at 10(-6) mbar, a degradation of the isolation exceeding 10 dB was observed. A remotely controlled system using a motorized lambda=2 waveplate inserted between the first polarizer and the Faraday rotator has proven its capability to restore the optical isolation to a value close to the one set up in air.

Abstract
PURPOSE The authors retrospectively reviewed six cases of histologically proven Erdheim-Chester disease (ECD) to evaluate organ involvement and clinical and radiological findings. MATERIALS AND METHODS Through a search of the pathology databases of four Italian hospitals, we identified six men (mean age, 56 years) with a histological diagnosis of ECD. Histology was performed on retroperitoneal or pulmonary biopsy, depending on disease involvement on imaging. Patients underwent plain radiography of the lower limbs and chest, total-body computed tomography (CT) and bone scintigraphy. Magnetic resonance (MR) imaging was performed in two patients to evaluate the lower limbs and in one patient to study the brain, the chest and the abdomen. RESULTS Clinical manifestations included dyspnoea (n=2), hydronephrosis (n=2) and bone pain (n=1). Bilateral symmetrical osteosclerosis of the metaphyseal and diaphyseal portions of the lower-limb long bones was present in five patients. Imaging studies revealed extraskeletal manifestations in all patients, including involvement of the retroperitoneal space (n=4), the lung (n=4) and the heart (n=2). CONCLUSIONS ECD is a multiorgan disease that displays constant involvement of the bones and retroperitoneum; in particular, of the perirenal fat. Although the diagnosis of ECD is histological, imaging can raise suspicion and help to establish a presumptive diagnosis.

Abstract
AIMS To compare the effect of continuous subcutaneous insulin infusion (CSII) and multiple daily insulin injections (MDI) on albumin excretion rate (AER) in Type 1 diabetic patients. METHODS In a 3-year multicentre retrospective observational study, 110 Type 1 diabetic patients treated with CSII were compared with 110 patients treated with MDI matched at baseline for age, sex, diabetes duration and HbA(1c). At entry, 90 patients in each group had normal AER and 20 persistent microalbuminuria. AER, estimated glomerular filtration rate (eGFR), HbA(1c,) lipids and blood pressure were assessed. RESULTS HbA(1c) was lower in the CSII than in the MDI group (8.1 +/- 0.9 vs. 8.4 +/- 1.3%; P < 0.005 after 3 years). Blood pressure and eGFR were similar during the study. AER [median (95% confidence interval)], similar at baseline [6.0 microg/min (9, 21) in the CSII group vs. 4.4 (8, 16) in the MDI group, NS] was significantly lower in the patients treated with CSII both at year 2 and at year 3 of follow-up [4.7 microg/min (6, 12) vs. 6.4 (13, 29), P < 0.002]. This difference was observed even when normo- and microalbuminuric patients were analysed separately. Nine patients progressed to microalbuminuria in the MDI group and only one in the CSII group. Nine patients regressed to normoalbuminuria in the CSII group, whereas only two regressed to normoalbuminuria in the MDI group. CONCLUSIONS Despite a small benefit in terms of improved glycaemic control, CSII therapy may be useful in decreasing the progressive increase in AER in Type 1 diabetic patients.

Immune-mediated liver dysfunction after antiviral treatment in liver transplanted patients with hepatitis C: allo or autoimmune de novo hepatitis? Dig Liver Dis 2009; 41:345-9.

Abstract
BACKGROUND The recurrence of hepatitis C after liver transplantation is extremely frequent. Antiviral therapy combining pegylated-interferon with ribavirin is therefore increasingly used in these patients. It has been recently reported, however, that during antiviral treatment a hepatic immune-mediated liver dysfunction, similar to "de novo" autoimmune hepatitis, may develop in a few transplanted patients. PATIENTS AND METHODS Three patients, treated with pegylated-interferon alpha-2a and ribavirin for recurrent hepatitis C after liver transplantation, developed an aggressive hepatitis with clinical, biochemical, and histological features similar to those of autoimmune hepatitis. RESULTS In all three patients, a liver enzymes increase was evident after hepatitis C virus-RNA had become undetectable. Diagnosis of "de novo" autoimmune hepatitis was proposed, based on the presence of high-titre circulating autoantibodies and liver histology features. Following the introduction of a steroid therapy, clinical and biochemical parameters progressively improved. Hepatitis C virus infection, however, relapsed after a few months in all the patients. CONCLUSIONS Following liver transplantation, antiviral therapy with pegylated-interferon alpha-2a and ribavirin for recurrent hepatitis C may be associated, in a few patients, with severe immune-mediated graft dysfunction similar to autoimmune hepatitis.

Abstract
We describe a model evaluating changes in the optical isolation of a Faraday isolator when passing from air to vacuum in terms of different thermal effects in the crystal. The changes are particularly significant in the crystal thermal lensing (refraction index and thermal expansion) and in its Verdet constant and can be ascribed to the less efficient convection cooling of the magneto-optic crystal of the Faraday isolator. An isolation decrease by a factor of 10 is experimentally observed in a Faraday isolator that is used in a gravitational wave experiment (Virgo) with a 10 W input laser when going from air to vacuum. A finite element model simulation reproduces with a great accuracy the experimental data measured on Virgo and on a test bench. A first set of measurements of the thermal lensing has been used to characterize the losses of the crystal, which depend on the sample. The isolation factor measured on Virgo confirms the simulation model and the absorption losses of 0.0016 +/- 0.0002/cm for the TGG magneto-optic crystal used in the Faraday isolator.

Abstract
The gamma decay associated with the warm rotation of the superdeformed nuclei 151Tb and 196Pb has been measured with the EUROBALL IV array. Several independent quantities provide a stringent test of the population and decay dynamics in the superdeformed well. A Monte Carlo simulation of the gamma decay based on microscopic calculations gives remarkable agreement with the data only assuming a large enhancement of the B(E1) strength for 1-2 MeV gamma rays, which may be related to the evidence for octupole vibrations in both mass regions.

Abstract
PURPOSE This study aimed to assess the usefulness of multiplanar reformations (MPR) during multidetector-row computed tomography (MDCT)-guided percutaneous needle biopsy of lung lesions difficult to access with the guidance of the native axial images alone owing to overlying bony structures, large vessels or pleural fissures. MATERIALS AND METHODS MDCT-guided transthoracic needle biopsy (TNB) was performed on 84 patients (55 men and 29 women; mean age 65 years) with suspected lung neoplasm by using a spiral MDCT scanner with the simultaneous acquisition of six slices per rotation. We determined the site of entry of the 22-gauge Chiba needle on native axial images and coronal or sagittal MPR images. We took care to ensure the shortest needle path without overlying large vessels, main bronchi, pleural fissures or bony structures; access to the lung parenchyma as perpendicular as possible to the pleural plane; and sampling of highly attenuating areas of noncalcified tissue within the lesion. RESULTS Diagnostic samples were obtained in 96% of cases. In 73 patients, lesions appeared as a solid noncalcified nodule <2 cm; 11 lesions were mass-like. In 22, the biopsy required MPR guidance owing to overlying ribs (18), fissures (2) or hilar-mediastinal location (2). CONCLUSIONS MDCT MPR images allowed sampling of pulmonary lesions until now considered unreachable with axial MDCT guidance because of overlying bony structures (ribs, sternum and scapulae) or critical location (hilar-mediastinal, proximity to the heart or large vessels). Compared with the conventional procedure, the use of MPR images does not increase the rate of pneumothorax or the procedure time.

Abstract
BACKGROUND AND AIMS Diabetic dyslipidaemia contributes to the increased risk of cardiovascular disease in patients with Type 2 diabetes. This paper examines the effectiveness of adding pioglitazone to metformin or a sulphonylurea (SU) compared with a fixed-dose combination of metformin and glibenclamide on diabetic dyslipidaemia in patients with Type 2 diabetes. METHODS AND RESULTS Patients (n=250) treated with metformin (< or =3g/day) or an SU as monotherapy at a stable dose for > or =3 months were randomised to receive either pioglitazone (15-30 mg/day) in addition to their metformin or SU, or a fixed-dose combination tablet containing metformin (400mg) and glibenclamide (2.5 mg) [up to 3 tablets daily] for 6 months. Addition of pioglitazone tended to increase plasma high-density lipoprotein-cholesterol (HDL-C) [0.04 mmol/L; P=0.051] at 6 months and significantly reduced plasma triglycerides (-0.25 mmol/L; P=0.013) compared with baseline. Patients treated with metformin/glibenclamide for 6 months had reduced HDL-C (-0.09 mmol/L; P<0.01) and no change in plasma triglyceride levels (0.03 mmol/L; P=0.733). Both treatment regimes resulted in a similar level of glycaemic control. CONCLUSION The beneficial effects of pioglitazone on diabetic dyslipidaemia may help combat the increased cardiovascular morbidity and mortality observed in patients with Type 2 diabetes while providing stable glycaemic control.

Abstract
Some uncommon diseases may involve the central airways focally or diffusely. These include Wegener's granulomatosis, relapsing polychondritis, tracheobronchopathia osteochondroplastica, amyloidosis, papillomatosis, rhinoscleroma, sarcoidosis and tuberculosis. Related computed tomography (CT) findings essentially include calcifications, luminal stenosis, wall thickening and nodules. The purpose of this paper is to help refine the differential diagnosis among these diseases through the use of multidetector CT (MDCT) imaging.

Abstract
Pheochromocytomas are catecholamine-producing neuroendocrine tumours arising from chromaffin cells of the adrenal medulla or extra-adrenal paraganglionic system that show 2 distinctive features, rarity and clinical variability. Pheochromocytoma occasionally is associated with pathological lesions of the adrenal cortex. We present 2 cases of patients referred to our hospital with a finding of clinical suspected pheochromocytoma. Both of them were hypertensive; the first patient with typical symptoms of pheochromocytoma and the second patient with chest pain and hypertension resistant to pharmacological treatment. The diagnosis of pheochromocytoma was confirmed in both cases with laboratory analysis and the lesion was achieved by employing 3 imaging techniques: computed tomography (CT), magnetic resonance imaging (MRI) and scintigraphy with (123)I-metaiodobenzilguanidine (MIBG). The patients underwent adrenalectomy and in the same adrenal gland we found a pheochromocytoma associated with a nonfunctioning cortical adenoma. As far as we know few cases with this association are available in the literature.

AIM To study the incidence of visual loss over a 12-year period in the survivors of an original cohort aged 40 years or older at baseline. METHODS Visual acuity (VA) was measured by means of a standardized logMAR chart. World Health Organization definition of blindness and low vision was adopted (respectively, best-corrected VA >1.3 logMAR or a visual field <10 degrees around central fixation, and best-corrected VA >0.5-1.3 logMAR or a visual field <20 degrees around central fixation). Moreover, binocular visual loss incidence (VA>0.5 logMAR) was calculated in a 'healthy' group who had uncorrected VA of 0.0 logMAR or better in both eyes at baseline and absence of eye diseases. RESULTS Of the 584 eligible survivors, 411 (70.7%) had a 12-year follow-up visit. The overall incidence figures were as follows: best-corrected binocular blindness (0.7%), binocular low vision (3.9%), monocular blindness (2.7%), and monocular low vision (5.0%), respectively. The results for presenting VAs were 1.2, 9.5, 4.2, and 15.3%. Figures for uncorrected, best-corrected, and presenting binocular visual loss incidence in the 'healthy' group were respectively 12.7, 0.9, and 3.7%. CONCLUSION The discrepancy between the ideal and real situations that emerges from this study has important implications for health-care planning. Over a period of 12 years, a substantial percentage of 'healthy' subjects will have to seek medical care. Incident visual loss was caused mainly by untreated cataract, glaucoma, myopia, and age-related macular degeneration.

Abstract
PURPOSE On-line hemodiafiltration (HDF) is gaining popularity due to increasing evidence of clinical benefits. The purpose of this study was to test a new on-line technique paired hemodiafiltration (PHF). In addition, we evaluated the PHF system during in vitro contamination. METHODS Five patients used the PHF technique over a 6-month period. We performed a disinfection protocol and tested for bacteria, endotoxin, halogenated carbons and metals in the feed water, and we tested for bacteria, endotoxins and fungi in the dialysate after different ultrafiltration stages. In vitro tests were performed using three bacterial concentrations of pseudomonas aeruginosa. Samples were analyzed from different sites throughout the entire on-line HDF circuit for bacteria endotoxins, fungus and the ability to stimulate whole blood production of tumor necrosis factor-alpha (TNF-alpha). RESULTS The bacteriological control from the feeding machine water and at the entrance to the monitors had a bacterial level of <100 CFU/mL. No bacteria were detected in the dialysate and endotoxin levels were <0.03 EU/mL. In the in vitro contamination study, with the three bacterial concentrations tested at various points in the circuit, bacterial and fungi were below the level of detection and endotoxins were <0.03 UE/mL. The addition of dialysate samples taken after the 1st microfiltration stage, as well as after the 1st and 2nd ultrafiltration stage and incubated with whole blood were not associated with stimulated TNF-alpha production. CONCLUSIONS PHF appeared to be a safe and feasible method for on-line HDF even in the unforeseen presence of the bacterial contamination of the feed water or in the water distribution system.

Abstract
AIM To validate the Italian version of the World Health Organization (WHO)-Well-Being Questionnaire (WBQ) and the WHO-Diabetes Treatment Satisfaction Questionnaire (DTSQ) in Type 1 and Type 2 diabetic patients. METHODS The cultural adaptation of the questionnaires was performed by using standard forward/backward techniques. Internal consistency reliability was estimated by Cronbach's alpha coefficient. Construct validity was evaluated using the Short Form-36 (SF-36) Health Status Questionnaire. Finally, the discriminative properties of the questionnaires were evaluated relative to the patients' characteristics. The questionnaires were administered to a random sample of patients identified in twelve outpatient diabetes clinics. RESULTS Overall, 412 subjects were recruited, of whom 96 (23%) with Type 1 diabetes. Item-scale correlations were >0.40 for all the items. Cronbach's alpha coefficient was 0.86 for the WHO-DTSQ and ranged between 0.79 and 0.91 for the WHO-WBQ. High correlations were found between WHO-WBQ scales and the mental dimensions of the Short Form-36 (SF-36) questionnaire, but not between WHO-DTSQ and SF-36 scores. Women, obese subjects, those with longer diabetes duration and multiple complications showed a worse quality of life in all of the four areas of the WHO-WBQ. In Type 2 diabetic subjects, SF-36 scores, but not WHO-WBQ scores, were able to discriminate the population according to the treatment modalities. Lower levels of treatment satisfaction were related to female gender, longer diabetes duration, insulin treatment, presence of diabetes complications and HbA1c levels >7.0%. The flexibility of the treatement was perceived as a major problem even among patients treated with oral agents. CONCLUSIONS The WHO-DTSQ can be considered as a valuable instrument to be used internationally for the description of diabetes treatment satisfaction. The WHO-WBQ also shows adequate psychometric properties, but additional data are needed to clarify whether it is more sensitive than SF-36, the most widely used generic instrument.

Abstract
Fibrous dysplasia of bone (FD) is caused by somatic mutations of the GNAS1 gene, which lead to constitutive activation of adenylyl cyclase and overproduction of cAMP in osteogenic cells. Previous in vitro studies using nonclonal, heterogeneous strains of FD-derived cells suggested that IL-6 might play a critical role in promoting excess osteoclastogenesis in FD. In this study, we investigated IL-6 expression in FD in situ and its relationship to the actual patterns of osteoclastogenesis within the abnormal tissue. We found that osteoclastogenesis is not spatially restricted to bone surfaces in FD but occurs to a large extent ectopicly in the fibrous tissue, where stromal cells diffusely express IL-6 mRNA and exhibit a characteristic cell morphology. We also observed specific expression of IL-6 mRNA in a proportion of osteoclasts, suggesting that an autocrine/paracrine loop may contribute to osteoclastogenesis in vivo in FD, as in some other bone diseases, including Paget's disease. We also generated homogeneous, clonally derived strains of wild-type and GNAS1-mutated stromal cells from the same individual, parent FD lesions. In this way, we could show that mutated stromal cells produce IL-6 at a basal magnitude and rate that are significantly higher than in the cognate wild-type cells. Conversely, wild-type cells respond to db-cAMP with a severalfold increase in magnitude and rate of IL-6 production, whereas mutant strains remain essentially unresponsive. Our data establish a direct link between GNAS1 mutations in stromal cells and IL-6 production but also define the complexity of the role of IL-6 in regulating osteoclastogenesis in FD in vivo. Here, patterns of osteoclastogenesis and bone resorption reflect not only the cell-autonomous effects of GNAS1 mutations in osteogenic cells (including IL-6 production) but also the local and systemic context to which non-osteogenic cells, local proportions of wild-type vs mutated cells, and systemic hormones contribute.
