The type and frequency of neurological manifestations of Behçet’s disease (BD) vary with ethnicity. We analyzed the neurological manifestations of BD in Japanese patients. All patients undergoing treatment at one of the two Yokohama City University hospitals from July 1991 to December 2007 and who fulfilled the Japanese criteria for BD revised in 1987 were(More)
Bone metabolism is dependent on cells of the osteoblast and osteoclast lineage. These cells play a major role in the synthesis and degradation of osteoid and in its mineralization and demineralization. Bone cells are under the influence of various systemic and local auto/paracrine factors. One further regulatory element that can play both a sensory/(More)
INTRODUCTION Interstitial Lung Disease (ILD) is frequently associated with Rheumatoid Arthritis (RA) as one of extra-articular manifestations. Many studies for Human Leukocyte Antigen (HLA) allelic association with RA have been reported, but few have been validated in an RA subpopulation with ILD. In this study, we investigated the association of HLA class(More)
OBJECTIVE To study tissue inhibitor of metalloproteinase 1 (TIMP-1) in relation to collagenolytic and gelatinolytic potential, namely dinitrophenyl-Pro-Gln-Gly-Ile-Ala-Gly-Gln-D-Arg (DNP-S) sensitive proteolytic activity, in loose total hip arthroplasty (THA) endoprostheses. METHODS Tissue localization of TIMP-1 was investigated immunohistochemically.(More)
We have explored the tissue localization of extracellular matrix metalloproteinases MMP-1 (fibroblast collagenase), MMP-2 (72-kDa gelatinase/Type IV collagenase), MMP-3 (stromelysin), MMP-8 (polymorphonuclear leukocyte collagenase) and MMP-9 (92-kDa gelatinase/Type IV collagenase) in the tissues around loose hip prostheses. The findings were compared with(More)
Because of the lack of adequate strength and toughness, hydroxyapatite (HA) ceramic can not be used for a substitute for a bone and joint despite its excellent affinity for the bone. The present authors have succeeded in producing a new type of HA ceramic containing zirconia. This new ceramic material is superior to ordinary HA ceramic in quality and(More)
Interferon regulatory factor 2 (IRF2) negatively regulates type I interferon (IFN) responses, while it plays a role in induction of Th1 differentiation. Previous linkage and association studies in European-American populations suggested genetic role of IRF2 in systemic lupus erythematosus (SLE); however, this observation has not yet been confirmed. No(More)
Neurolathyrisim is a motor neuron disease characterized by spastic paraparesis in the hind legs, and is caused by grass pea, Lathyrus sativus, which contains the excitotoxic amino acid, 3-N-oxalyl-L-2,3-diaminopropanoic acid (L-β-ODAP), an α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA)-type glutamatergic receptor agonist. In an attempt to make(More)
Clinical phenotypes of Behçet disease (BD) vary among ethnic groups. We chronologically analyzed the clinical manifestations of BD in 412 patients meeting the Japanese criteria for BD seen at 2 Yokohama City University hospitals from July 1991 to December 2007. We examined the onset of individual symptoms in each patient. A single initial symptom appeared(More)
The thrombopoietic status of patients with uremia remains unclear. This issue was addressed with particular reference to marrow megakaryocytopoiesis and endogenous thrombopoietin (TPO) levels. A study was conducted in 114 patients on hemodialysis, 43 patients on continuous ambulatory peritoneal dialysis, and 48 age-matched controls. Reticulated platelets, a(More)
