BACKGROUND Nonalcoholic fatty liver disease(NAFLD) includes two distinct conditions, with different histologic features and prognosis: non-alcoholic fatty liver(NAFL) and non-alcoholic steatohepatitis(NASH). Furthermore, NASH is the more aggressive necro-inflammatory form, which may accumulate fibrosis and result in End stage liver disease(ESLD). NAFLD is also linked to systemic inflammatory conditions such as psoriasis. NAFLD is currently the most common cause of ESLD in Western countries, becoming a serious public health *** suppurativa(HS) is a systemic inflammatory/autoinflammatory disease of the terminal follicular epithelium of the apocrine gland with a prevalence of 0.05% to 4.10%. Due to its systemic inflammatory behavior several comorbidities were recently associated, however liver ones were scarcely *** To evaluate the prevalence and characteristics of NASH/NAFL in HS *** This retrospective study is a sub-analysis of a larger study carried out in 4 Italian dermatological centers. In this cohort, there were 83 patients: 51 patients with HS only, 20 patients with HS/NAFL and 12 with HS/*** Inflammatory comorbidities were present in 3.9% of HS only patients, 25% of HS/NAFL patients and 58.3% of HS/NASH patients(P < 0.001). Similarly, mean Autoinflammatory Disease Damage Index(ADDI) was significantly higher among patients with HS/NASH(5.3 ± 2.2, P < 0.001) compared to patients with HS/NAFL or HS only(2.8 ± 1.6 and 2.6 ± 1.4 respectively). Furthermore, ADDI correlates with IHS4 in HS, HS/NAFL and HS/NASH. Diabetic patients have higher Hurley score than not diabetic ones. Ultrasound examination was significantly different in the three *** HS patients displayed a high prevalence of NASH/NAFLD and ultrasound examination should be particularly addressed to patients that display high ADDI scores.

Exploitation of variability displayed by wild Solanum species for breeding the cultivated potato (S. tuberosum) requires phenotypic and genotypic characterization of germplasm resources. In the present work, a collection of 15 wild Solanum species was investigated for resistance to pathotype Ro2 of the nematode Globodera rostochiensis. Most of the genotypes reduced reproduction of the nematode, compared to the control variety Spunta, a highly resistant genotype being an accession of S. tuberosum spp. andigena. The genetic variability of the Gro1 gene cluster, which confers resistance to some pathotypes of G. rostochiensis, was then studied in the Solanum species used in this study. For this purpose, SCAR markers for eight paralogues of Gro1 gene were developed. No species showed the same pattern of the resistant control genotype. Moreover, wide-genome variability was also assessed by using AFLP markers, which allowed species-specific markers to be identified for each genotype analyzed.

AIMTo treated with electrochemotherapy (ECT) a prospective case series of patients with liver cirrhosis and Vp3-Vp4- portal vein tumor thrombus (PVTT) from hepatocellular carcinoma (HCC), in order to evaluate the feasibility, safety and efficacy of this new non thermal ablative technique in those *** patients (5 males and 1 female), aged 61-85 years (mean age, 70 years), four in Child-Pugh A and two in Child-Pugh B class, entered our study series. All patients were studied with three-phase computed tomography (CT), contrast enhanced ultrasound (CEUS) and ultrasound-guided percutaneous biopsy of the thrombus before ECT. All patients underwent ECT treatment (Cliniporator Vitae®, IGEA SpA, Carpi, Modena, Italy) of Vp3-Vp4 PVTT in a single session. At the end of the procedure a post-treatment biopsy of the thrombus was performed. Scheduled follow-up in all patients entailed: CEUS within 24 h after treatment; triphasic contrast-enhanced CT and CEUS at 3 mo after treatment and every six months ***-treatment CEUS showed complete absence of enhancement of the treated thrombus in all cases. Post-treatment biopsy showed apoptosis and necrosis of tumor cells in all cases. The follow-up ranged from 9 to 20 mo (median, 14 mo). In 2 patients, the follow-up CT and CEUS demonstrated complete patency of the treated portal vein. Other 3 patients showed a persistent avascular non-tumoral shrinked thrombus at CEUS and CT during follow-up. No local recurrence was observed at follow-up CT and CEUS in 5/6 patients. One patient was lost to follow-up because of death from gastrointestinal hemorrage 5 wk after *** patients with cirrhosis, ECT seems effective and safe for curative treatment of Vp3-Vp4 PVTT from HCC.

Creep-fatigue is a damage mechanism where cyclic deformation damage （fatigue） is enhanced by creep damage and vice versa. Factors affecting the creep-fatigue damage are stress level （or, equivalently, strain range）, temperature, hold time period, material softening/hardening and number of cycles. Moreover, environmental effects can accelerate the creep-fatigue interaction （oxidation, hot corrosion, irradiation, etc.）. The activity described in this paper was planned to perform tests on 9Cr-lMo ferritic/martensitic steel （P91） combining fatigue cycles and constant tensile and compressive holding periods. A preliminary basic fatigue characterization campaign in the LCF （low cycle fatigue） regime was carried out by performing a series of strain controlled tests, each at the same temperature （550 ℃）, using two different values for the total strain range （1% and 0.6%） and the same total strain rate （2×10^-3 s^-1）. The tests were carried out with a strain ratio of-l, i.e., in fully reversed cyclic conditions. In this paper we illustrate the results obtained by testing in air P91 （9Cr-lMo） ferritic/martensitic steel, introducing different dwell periods （either in strain or load control） and obsetwing how these affect the fatigue life of the specimens. The final aim of the activity is to investigate how much detrimental is the effect of the holding periods on the fatigue life in order to validate the creep-fatigue interaction diagram presently adopted in RCC-MRx code for the P91 steel.

Hepatitis B virus(HBV) infection has shown an intermediate or high endemicity level in low-income countries over the last five decades. In recent years, however, the incidence of acute hepatitis B and the prevalence of hepatitis B surface antigen chronic carriers have decreased in several countries because of the HBV universal vaccination programs started in the nineties. Some countries, however, are still unable to implement these programs, particularly in their hyperendemic rural areas. The diffusion of HBV infection is still wide in several low-income countries where the prevention, management and treatment of HBV infection are a heavy burden for the governments and healthcare authorities. Of note, the information on the HBV epidemiology is scanty in numerous eastern European and Latin-American countries. The studies on molecular epidemiology performed in some countries provide an important contribution for a more comprehensive knowledge of HBV epidemiology, and phylogenetic studies provide information on the impact of recent and older migratory flows.

AIM:To evaluate short- and long-term efficacy of endoscopic balloon dilation in a cohort of consecutive patients with symptomatic Crohn's disease (CD)-related strictures. METHODS:Twenty-six CD patients (11 men; median age 36.8 year, range 11-65 years) with 27 symptomatic strictures underwent endoscopic balloon dilation (EBD).Both naive and post-operative strictures, of any length and diameter, with or without associated fistula were included. After a clinical and radiological assessment, EBD was performed with a Microvasive Rigiflex through the scope balloon system. The procedure was considered successful if no symptom reoccurred in the following 6 mo. The long-term clinical outcome was to avoid surgery. RESULTS:The mean follow-up time was 40.7 ± 5.7 mo (range 10-94 mo). In this period, forty-six EBD were performed with a technical success of 100%. No procedure-related complication was reported. Surgery was avoided in 92.6% of the patients during the entire follow-up. Two patients, both presenting ileocecal strictures associated with fistula, failed to respond to the treatment and underwent surgical strictures resection. Of the 24 patients who did not undergo surgery, 11 patients received 1 EBD, and 13 required further dilations over time for the treatment of relapsing strictures (7 patients underwent 2 dilations, 5 patients 3 dilations, and 1 patient 4 dilations). Overall, the EBD success rate after the first dilation was 81.5%. No difference was observed between the EBD success rate for naive (n = 12) and post-operative (n = 15) CD related strictures (P > 0.05). CONCLUSION:EBD appears to be a safe and effective procedure in the therapeutic management of CD-related strictures of any origin and dimension in order to prevent surgery.
