A 49-year-old Japanese man with rheumatoid arthritis acutely developed a skin eruption and severe non-productive cough seventeen days after the administration of leflunomide. Because all bacteriology findings were negative, steroid pulse-therapy was initiated promptly due to the rapidity of chest X-ray progression and the deterioration of arterial blood(More)
UNLABELLED OBJECTIVE To examine the effects of a novel immunosuppressant, FTY720, on hematolymphoid cells and the clinical course of MRL-lpr/lpr (MRL/lpr) mice genetically predisposed to systemic lupus erythematosus (SLE). METHODS Apoptosis of hematolymphoid cells was determined in vitro by FACScan after staining with propidium iodide or merocyanine 540.(More)
In extravasation of T cells, little is known about the mechanisms of transendothelial migration subsequent to the T cells' tight adhesion to endothelium. To investigate these mechanisms, we developed a monoclonal antibody (mAb), termed anti-4C8, that blocks transmigration but not adhesion in a culture system in which high CD26-expressing (CD26(hi)) T cells(More)
The problem of reconstructing large-scale, gene regulatory networks from gene expression data has garnered considerable attention in bioinformatics over the past decade with the graphical modeling paradigm having emerged as a popular framework for inference. Analysis in a full Bayesian setting is contingent upon the assignment of a so-called structure(More)
We describe an unusual presentation of a localized form of polyarteritis nodosa (PAN) manifested by fever of undetermined origin (FUO). Biopsies of the gastrocnemius muscle revealed necrotizing arteritis and initiation of prednisolone (PSL) brought rapid response. The PAN localized to muscle is rare; furthermore, this disease presented as FUO is very rare.(More)
Protein-losing gastroenteropathy (PLGE) is a rare manifestation of primary Sjögren's syndrome (SS). We report a case of a 41-year-old Japanese man, who is the first male patient, with PLGE associated with primary SS. Although serum anti-SSA and SSB antibodies were detected, he had no subjective sicca symptoms. He had multiple annular erythema: a(More)
