results hla-drb1*07 (rr 5.3, p = 0.0008) and hla-drb1*08 (rr n.c. p = 0.0005) were significantly associated with the risk of pbc development. patients younger than 45 years had significantly higher alanine aminotransferase (p = 0.038) and alkaline phosphatase levels (p = 0.047) than older cases. in comparison to non-cc rs12979860, patients with cc rs12979860 genotype showed an early histologica...

an efficient protocol for the selective oxidation of primary alcohols to aldehydes withh5io6/v2o5 in ionic liquid [bmpy][pf6] has been developed. high yields of the products, mildreaction conditions and simple experimental procedure make this protocol complementary tothe existing methods. the catalyst can be reused for several times without obvious loss of thecatalytic activity.
