It was observed that the CoRuCr intermediate layers provide better C-axis orientation than
the Ru intermediate layers. The introduction of oxygen during the deposition of CoRuCr increases the C-axis dispersion slightly but it is still comparable to that of Ru intermediate layer. Grain size and grain size distribution were reduced with CoRuCr-oxide intermediate layers. Magnetic properties were also optimized, indicating that the CoRuCr-oxide intermediate layers are good candidates for perpendicular Fer-1 concentration recording media.

“The fungi, Beauveria bassiana (ATCC 13144) and Penicillium chrysogenium (ATCC 9480) transformed resveratrol (1) to resveratrol-3-O-sulphate (4). The former, in addition, gave 5-methoxyresveratrol-3-O–glucoside (2) with the latter yielding 5-methoxyresveratrol-3-O-sulphate (3). The structures were established by spectroscopic methods. Evaluation of
biological activity of metabolites through GSK1210151A research buy a series of mammalian cell based assays indicated that resveratrol tends to lose its anti-inflammatory, cytotoxic and anti-oxidant activities with the substitution of its hydroxyl groups.”
“Background: The causal association between hepatitis virus infections and lichen planus (LP) remains a matter of controversy. Reliable figures for German patients are still lacking.
Patients and Methods: We analyzed the prevalence of serum antibodies against hepatitis B and C viruses p38 MAPK pathway (HBV, HCV) in 265 LP patients and compared the results to 257 patients with
chronic urticaria (URT) and 222 patients with malignant melanoma (MM). Additionally, we analyzed age- and sex-specific differences.
Results: The prevalence of HBV (13.2% or 14.7%) antibodies was significantly higher in patients with LP and URT patients than in the MM control group (HBV: 5.4%, p < 0.001). The prevalence of HCV antibodies among LP and URT patients (2.6% or 0.8%) was not significantly greater (p > 0.05) than in MM patients (0.4%). The prevalences of HBV and HCV in the MM control group were comparable to those in the general German population (HBV: 5-8%, HCV: 0.4-0.7%). An analysis by sub-groups showed that these differences resulted from sex- and age-dependent prevalences. HBV antibodies were significantly more common only in male LP patients (16.1%) and in male (20.0%) and female URT patients (15.6%) aged 31-60 years. The greater prevalence of HCV in female LP patients older than 60 years of age was not significant.
Conclusions: LP is not specifically associated with hepatitis B or C antibodies in the Caucasian population of Germany. The higher prevalences of HBV antibodies found in LP and URT patients may be a reflection of age- and sex- related factors rather than disease-specific exposure to HBV infections.
