OBJECTIVE Diet composition alters the metabolic states of adipocytes and hepatocytes in diabetes. The effects of dipeptidyl peptidase-4 (DPP-4) inhibition on adipose tissue inflammation and fatty liver have been obscure. We investigated the extrapancreatic effects of DPP-4 inhibition on visceral fat and the liver. RESEARCH DESIGN AND METHODS We(More)
Type 2 diabetes is characterized by diminished pancreatic β-cell mass and function. Glucagon-like peptide-1 has been reported to increase islet cell proliferation and reduce apoptosis of β-cells in rodents. In this study, we explored the effect of chronic administration of the dipeptidyl peptidase-4 inhibitor vildagliptin on glucose tolerance, β-cell(More)
Decreased β-cell mass is a hallmark of type 2 diabetes, and therapeutic approaches to increase the pancreatic β-cell mass have been expected. In recent years, gastrointestinal incretin peptides have been shown to exert a cell-proliferative effect in pancreatic β-cells. Trefoil factor 2 (TFF2), which is predominantly expressed in the surface epithelium of(More)
BACKGROUND The rate of metabolism in the intestine of oral administered FK506 decreases as FK506 passes on to the lower intestine. In transplant recipients with diarrhea given oral FK506, the main areas for absorption of FK506 shift to the lower intestine, where the ability to metabolize FK506 is weaker. Therefore it is considered likely that when FK506 is(More)
AIM Ezetimibe selectively blocks intestinal cholesterol absorption by inhibiting Niemann-Pick C1-like 1 (NPC1L1) and reducing LDL cholesterol (LDL-C). In animals, ezetimibe reversed diet-induced obesity, liver steatosis, and insulin resistance. In humans, its potential effects on liver steatosis and insulin resistance have been suggested. We investigated(More)
OBJECTIVE We investigated whether administration of mesenchymal stem cells (MSCs) promotes bone formation at the gap created by periosteal distraction. STUDY DESIGN A mesh plate was placed subperiosteally in rabbit parietal bones. Following elevation of the mesh plate, rabbit MSCs were administered into the gap. Controls received phosphate-buffered saline(More)
Studies from overseas have indicated that postprandial glucose excursions are predominant in subjects with moderate hyperglycemia, while fasting hyperglycemia become the predominant abnormality with worsening of hyperglycemia; however, few studies have yet investigated the correlation between HbA1c and fasting and/or postprandial hyperglycemia in Japanese(More)
PURPOSE We investigated the effect and safety of chemotherapy for patients over eighty-year-old. OBJECT Ten patients with advanced or recurrent pancreas or biliary tract cancer who were over 80 years old and administered gemcitabine hydrochloride (GEM), were named as "the oldest group", and compared with the control group. RESULT The overall response(More)
A visiting nursing service was provided for a female patient with the terminal stage of transverse colon cancer. The patient, who strongly wanted to stay at home, was discharged from hospital under continuous subcutaneous injection of morphine hydrochloride in late April 2001. The visiting nurse supported her life including the procedures for the continuous(More)
The precise role of AMP-activated protein kinase (AMPK), a target of metformin, in pancreatic β cells remains controversial, even though metformin was recently shown to enhance the expression of incretin receptors (GLP-1 and GIP receptors) in pancreatic β cells. In this study, we investigated the effect of AMPK in the regulation of incretin receptors(More)
