BACKGROUND Extraskeletal myxoid chondrosarcoma (EMC) is a rare malignant neoplasm. Despite a consensus for the distinct clinicopathologic entity of EMC, its clinical features remain controversial. In addition, most studies have contained a small number of patients who underwent definitive surgical treatment. METHODS Forty-two cases of EMC, which had been(More)
Nitric oxide (NO) produces rapid osteoclast detachment and contraction in vitro, and this effect is accompanied by a profound inhibition of bone resorption. Work by others has confirmed these findings in vivo: inhibition of NO synthase [NOS; L-arginine, NADPH: oxygen oxidoreductase (NO-forming), EC] in normal rats is followed by increased bone(More)
To investigate the immunogenic property of peptides derived from the synovial sarcoma-specific SYT-SSX fusion gene, we synthesized four peptides according to the binding motif for HLA-A24. The peptides, SS391 (PYGYDQIMPK) and SS393 (GYDQIMPKK), were derived from the breakpoint of SYT-SSX, and SS449a (AWTHRLRER) and SS449b (AWTHRLRERK) were from the SSX(More)
The human promyelocytic leukemia cell line HL60, when cultured in medium containing dimethyl sulfoxide (DMSO) or granulocyte colonystimulating factor (G-CSF), stopped dividing and differentiated into cells with granulocyte characteristics. We found that differentiated HL60 cells have no detectable cytolytic activity against cultured human bladder cell line(More)
Giant cell tumors of bone are a relatively common type of proliferative neoplasm. These tumors usually arise in the epiphyseal region of limbs and their occurrence in the ribs is unusual. This report describes two rare cases of giant cell tumor of the ribs. The tumors were resected with the ribs, and chest wall defects were covered with Marlex mesh. Both(More)
Incubation of peripheral blood lymphocytes from patients with bladder cancer in bestatin (specific inhibitor of aminopeptidase B and leucine aminopeptidase) solution resulted in a significant increase in the proportion of E-rosette-forming lymphocytes. The increase in the proportion of E-rosette-forming lymphocytes was abolished after reincubation with 100%(More)
