BACKGROUND Ischemia-reperfusion (I/R) injury associated with living donor liver transplantation impairs liver graft regeneration. Mesenchymal stem cells (MSCs) are potential cell therapeutic targets for liver disease. In this study, we demonstrate the impact of MSCs against hepatic I/R injury and hepatectomy. METHODOLOGY/PRINCIPAL FINDINGS We used a new(More)
Effect of subchronically administered GTS-21 [3-(2,4-dimethoxybenzylidene)-anabaseine dihydrochloride], a selective nicotinic agonist, on neuronal cell loss caused by nucleus basalis magnocellularis (nBM) lesion was studied in rats. After 2 weeks of bilateral nBM excitotoxic lesion, GTS-21 was orally administered once daily for 20 weeks. Neuronal cell loss(More)
CONTEXT Although surgical resection is the only curative therapeutic option for recurrent or metachronous pancreatic carcinomas, most such cancers are beyond surgical curability. We herein report on two rare cases of remnant pancreatectomy used to treat recurrent or metachronous pancreatic carcinomas. CASE REPORTS CASE#1 A 65-year-old male developed(More)
We report a 71-year-old man who had undergone pylorus-preserving pancreatoduodenectomy (PPPD) using PPPD-IV reconstruction for cholangiocarcinoma. For 6 years thereafter, he had suffered recurrent cholangitis, and also a right liver abscess (S5/8), which required percutaneous drainage at 9 years after PPPD. At 16 years after PPPD, he had been admitted to(More)
BACKGROUND Mesenchymal stem cells (MSCs) have been applied to the treatment of various diseases, and MSC administration in marginal donor grafts may help avoid the ischemia-reperfusion injury associated with solid organ transplants. Given the reports of side effects after intravenous MSC administration, local MSC administration to the target organ might be(More)
Effects of GTS-21 [3-(2,4-dimethoxybenzylidene)-anabaseine dihydrochloride], a selective nicotinic agonist, on locomotor activity and dopamine turnover were examined and compared to those of nicotine to test if GTS-21 exhibits side effects similar to those of nicotine. GTS-21 had no effect on locomotor activity in mice or dopamine turnover in rats. In(More)
BACKGROUND The aim of this study was to investigate factors that may improve the condition of a marginal kidney preserved with a normothermic solution following cardiac death (CD) in a model of rat kidney transplantation (RTx). METHODS Post-euthanasia, Lewis (LEW) donor rats were left for 1 h in a 23°C room. These critical kidney grafts were preserved in(More)
The development of organ preservation solutions and associated technology has been a major effort in tissue transplantation recently. However, this research takes a great deal of time and resources. In this study, a novel method for the evaluation of preservation solutions was established by using islet cells. Primary islets were obtained by hand-picking(More)
A 54-year-old Japanese woman was referred with a gallbladder tumor. Based on the results of the computed tomography scan, endoscopic retrograde cholangiopancreatography, and magnetic resonance cholangiopancreatography, a mucin-producing neoplasm of the gallbladder associated with pancreaticobiliary maljunction was diagnosed. Extended cholecystectomy,(More)
Translational research is necessary for the development of efficient experimental animal models that can be used to develop innovative medical treatments, such as improvements in organ or tissue transplantation. We have developed animal models that produce photogenic proteins in their islet cells: rats models expressing the gene for luciferase or green(More)
