In 1999, the Japan Diabetes Society (JDS) launched the previous version of the diagnostic criteria of diabetes mellitus, in which JDS took initiative in adopting glycated hemoglobin (HbA1c) as an adjunct to the diagnosis of diabetes. In contrast, in 2009 the International Expert Committee composed of the members of the American Diabetes Association (ADA)(More)
The aim of this study was to evaluate the effects of pioglitazone on clinical and metabolic parameters, body fat distribution, and serum adiponectin, a recently discovered antiatherosclerotic hormone, in Japanese patients with type 2 diabetes. Ten male patients aged 40 to 66 (57.7 +/- 7.4) years, who were being treated with dietary therapy alone (n = 7) or(More)
Matrix metalloproteinases (MMPs) have been reported to be the major factors responsible for aseptic loosening of artificial hip joints. So far, messenger ribonucleic acid (mRNA) expression patterns of seven MMPs have been reported, but that of many other MMPs which have been newly discovered or recently considered to be responsible for prosthetic loosening(More)
Osteoprotegerin (OPG) is a key regulator of osteoclastogenesis. We investigated the presence of OPG and bone-resorbing cytokines, the potential of osteoclastic differentiation in joint fluid from failed total hip arthroplasty (THA), and the inhibitory effect of OPG on osteoclast formation in vitro induced by the joint fluid. The study was aimed to clarify(More)
Matrix metalloproteinases (MMPs) and their endogenous inhibitors, tissue inhibitors of metalloproteinases (TIMPs), have been reported to play a critical role in extracellular degradation around artificial hip joints. Although messenger ribonucleic acid (mRNA) expression patterns of several MMPs and TIMPs were reported, there is no report of quantitative(More)
Activin A is a differentiation factor for β-cells and is effective to promote β-cell neogenesis. Activin A is also an autocrine activator of pancreatic stellate cells, which play a critical role in fibrogenesis of the pancreas. Conophylline (CnP) is a natural compound, which reproduces the effect of activin on β-cell differentiation and promotes β-cell(More)
Glutamic acid decarboxylase antibodies (GAD65Ab) are common in new onset Caucasian insulin-dependent diabetic (IDDM) patients but it is unclear if this marker is also prevalent in patients of other ethnic backgrounds. We determined antibodies against human recombinant GAD in Japanese diabetic patients using a radioimmunoassay with competition between in(More)
We investigated the efficacy of additional administration of 400 mg troglitazone (+T), which became available as a treatment for type 2 diabetes following the demonstration of its ability to reduce insulin resistance, in combination with diet (D + T) or sulfonylurea (S + T) therapy. Body fat area as determined by computed tomographic (CT) scanning at the(More)
OBJECTIVE We investigated the efficacy of epalrestat, an aldose reductase inhibitor, for diabetic peripheral neuropathy in Japanese patients with type 2 diabetes. METHODS A total of 38 type 2 diabetic patients (22 men and 16 women; mean ± S.E.M. age 63.3 ± 1.0 years; duration of diabetes 9.6 ± 0.8 years) with diabetic neuropathy were newly administered(More)
A polymorphism in the gene for cholesteryl ester transfer protein (CETP) has been reported to be associated with serum cholesterol levels and risk for atherosclerotic vascular diseases, and to clarify the relationship between the gene polymorphism for CETP and macroangiopathy in diabetes mellitus, a cross-sectional study was performed. The subjects of the(More)
