A total of 2150 consecutive adult patients treated with PEG-IFN plus RBV therapy in 46 Italian centres Bafilomycin A1 between 1 July 2004, and 30 June 2005, were studied. Of the 2150

patients, 923 (42.9%) (M/F 585/335, mean age 54.8 years) failed to achieve a serum HCV-RNA clearance. Of these 923 patients, 429 (46.5%) were nonresponders, 298 (32.3%) relapsers, 168 (18.2%) drop-outs for noncompliance or adverse events and 28 (3.0%) were lost during follow-up. Overall, 642 (70.6%) patients received adequate therapy (defined as more than 80% of the drug doses for > 80% of the time). Genotypes 1-4 were observed in 76.9% of cases; genotypes 2-3 in 21.2% and mixed in 1.9%, respectively. Multiple logistic regression analysis identified genotypes 1 and 4 as the sole independent predictors of the likelihood of nonresponse to therapy compared with relapse (OR: 4.38; 95% CI = 2.28-8.4). Age older than 65 years was the sole independent factor associated with no adherence to therapy (OR: 2.22; 95% CI = 1.36-3.62). Patients who fail to respond to treatment are a nonhomogeneous population with different features, and the sole factor that discriminates nonresponse from relapse is the distribution of genotypes 1-4. Co-morbidities are unable to determine

the type of treatment failure and inadequate adherence to therapy mostly affects patients older than 65 years of age.”
“Ferromagnetic resonance (FMR) was used to study the influence of miscut direction on the in-plane fourfold and uniaxial

selleck compound magnetic anisotropies of epitaxial Fe(3)O(4) films grown on vicinal MgO (100) surfaces. In-plane angular dependent measurements find more at room temperature on Fe(3)O(4) films on two different miscut directions (miscut along < 011 > and < 010 > directions) of MgO showed the presence of both in-plane fourfold (cubic) and in-plane uniaxial anisotropies. Temperature dependent FMR investigations show that the in-plane fourfold anisotropy constant (K(4)) is approximately the same for both samples at room temperature. The magnitude of K(4) increases gradually with decreasing temperature and changes sign from negative to positive values at 130 K. This behavior is consistent with that of bulk magnetite. In addition to K(4), we find an additional uniaxial component (K(2)), whose strength is quite different for the different miscut directions. The magnitude of K(2) shows very little or no temperature dependence. The observed differences in the magnitude of K(2) with miscut directions are related to the changes in the antiphase boundary structure and altered magnetic configurations at the boundaries.
