“We have investigated the electric field (EF) effect on the magnetic anisotropy energy

(MAE) in thin films MgO/Fe/M(001) (M = Au and Pt) by means of first-principles density-functional calculations. The EF dependence of the MAE is enhanced significantly in the film with the Pt substrate compared to that with the Au substrate. This enhancement is attributed to the EF-induced hybridization between Fe 3d- and Pt 5d-orbitals. This implies that the Pt layer stacked on the magnetic layer strengthens the sensitivity of devices for bias-voltage-induced magnetic control. (C) 2011 American Institute of Physics.

“Blue JNK-IN-8 clinical trial rubber bleb nevus syndrome is a rare vascular disorder characterized by cavernous angiomas of skin and

other organs including the gastrointestinal tract. The central nervous system involvement is seldom reported, Selleck SN-38 and neurological symptoms at onset in adulthood are extremely rare. Here, we describe a case of 82-year-old patient presenting multiple skin haemangiomas for some years, who was admitted for a brain hemorrhage. The MRI demonstrated the presence of multiple cavernous angiomas within the cerebral tissue.”
“Approximately 20% of hepatitis C virus (HCV) infected individuals clear the virus. Host factors that influence the course of HCV infection are still under investigation, and the data on the association of human leukocyte antigen (HLA) alleles and HCV clearance are scarce and controversial. The aims of this study were to investigate whether HLA alleles are associated with clearance of HCV infection in a highly admixed Brazilian population and whether these associations could be influenced by ethnicity and route of infection. HLA-A, -B, -C, -DRB1 and -DQB1 genotyping were performed in 135 HCV-infected Brazilian patients among which 45 cleared HCV infection (cases)

and 90 had persistent viral infection (controls). Controls were matched by sex, ethnicity (withes and non-whites) and route of infection (high infectious dose or low infectious dose). No significant association was identified BLZ945 molecular weight between HLA alleles and the outcome of HCV infection when analyzing the sample as a single group. However, a new protective association of HLA-DQB1*04 (P = 0.006; P-c = 0.030) and a rarely described association of HLA-DRB1*08 (P = 0.004; P-c = 0.048) were found only among white patients. The DRB1*11 allele, previously reported in homogeneous population, was associated with HCV clearance (P = 0.020) only among patients with expected high-dose exposure. These findings confirm the influence of ethnicity on the associations of HLA with spontaneous viral clearance of HCV infection and emphasize the possible influence of route of infection in this process.”
