The risk for hepatocellular carcinoma (HCC) among asymptomatic hepatitis C virus (HCV) carriers is not well understood. A community-based prospective study was conducted for over 8 years by record linkage to the Osaka Cancer Registry. The subjects were 1,927 individuals who were positive for anti-HCV through screening for second-generation HCV antibody(More)
BACKGROUND In antibody-mediated nonhemolytic transfusion reactions, transfusion-related acute lung injury (TRALI) tends to occur typically within 2 hours after a blood transfusion. White cell antibodies or immune complexes have been frequently shown to be associated with the syndrome, although the mechanisms by which they induce TRALI are poorly understood.(More)
BACKGROUND Antibodies to neutrophil antigens have been implicated in neonatal alloimmune neutropenia, autoimmune neutropenia, and transfusion-related acute lung injury. Most often, neutrophil-specific antibodies are directed toward human neutrophil antigen (HNA)-1 (Fcgamma receptor 3b) and HNA-2a (CD177) in these disorders. STUDY DESIGN AND METHODS To(More)
BACKGROUND Differential agglutination procedures and flow cytometric analysis have been used for detecting and quantitating mixed cell populations. For more than 20 years in our laboratory, a differential agglutination method using the coil planet centrifuge and polyclonal anti-A or anti-B has been used. However, it is now difficult to obtain polyclonal(More)
Although cyclic AMP has been considered to regulate cell proliferation, the mechanism of this function is largely unknown. Recent studies suggest that cyclic AMP promotes the proliferation of skin cells in a dose-dependent manner. An ointment containing dibutyryl cyclic AMP has been used in the treatment of skin ulcers and found to be effective in promoting(More)
