Although the liver is the most common site for pancreatic islet transplantation, it is not optimal. We compared kidney, liver, muscle, and omentum as transplantation sites with regard to operative feasibility, and the efficiency of implantation and glycemic control. Islets from C57BL/6 mice were transplanted into diabetic syngeneic recipients. The mean(More)
Disease amelioration by mesenchymal stem cells (MSCs) has been shown to be closely related to their immunomodulatory functions on the host immune system in many disease models. However, the underlying mechanisms of how these cells affect the immune cells in vivo are not fully understood. In this study, we report findings that a small but significant number(More)
Intraductal administration of a c-Jun NH(2)-terminal kinase (JNK) inhibitor enhances islet viability. However, its role in reducing the inflammatory response in islets is unknown. It is also unknown whether a JNK inhibitor could act in synergy with statins. We examined if the sequential combination of a JNK inhibitor and simvastatin would reduce islet(More)
Ex situ electrokinetic (EK) bioremediation of a laboratory-prepared pentadecane-contaminated kaolinite was carried out. Extraneous bacteria and ionic nutrients were continuously supplied to the soil specimen by a new electrolyte circulation method, which controlled electrical pH change of electrolyte solution to keep bacterial activity. During the EK(More)
BACKGROUND Due to increasing preclinical study using the rhesus monkeys, the physiological data of these monkeys are very important for the objective evaluation of experimental results. Here, we report the physiological values of the Chinese rhesus monkeys acclimated under a well-controlled laboratory environment. METHODS Seventy healthy rhesus monkeys of(More)
Highly selective detection, rapid response (<20 s), and superior sensitivity (Rair/Rgas> 50) against specific target gases, particularly at the 1 ppm level, still remain considerable challenges in gas sensor applications. We propose a rational design and facile synthesis concept for achieving exceptionally sensitive and selective detection of trace target(More)
Pore-loaded WO3 nanofibers (NFs) functionalized with spherical catalyst films were achieved via electrospinning combined by the sacrificial templating route using layer-by-layer (LbL) catalyst assembled polystyrene (PS) colloids. The catalyst-loaded porous WO3 NFs exhibited significantly improved toluene and acetone detection capability for potential(More)
Liver failure due to ischemia-reperfusion injury, believed to be closely related to the generation of oxygen-free radicals, is a serious problem during liver surgery. Gabexate mesilate, a synthetic protease inhibitor, suppresses the extracellular release of oxygen-free radicals in the microvascular endothelium. To determine its effects on(More)
BACKGROUND Memory T cells specific for donor antigens are currently recognized as a significant barrier for maintaining a successful transplant. Furthermore, it has been shown that commonly used immunosuppressive drugs do not alleviate this memory response. Here, we report that rapamycin allows significant proliferation of memory T cells and bortezomib can(More)
BACKGROUND AND PURPOSE We investigated whether focal hyperintensity on fluid-attenuated inversion recovery image within acute infarcts is associated with symptomatic intracerebral hemorrhage (SICH) after thrombolysis. METHODS Patients with acute ischemic stroke who underwent MRI screening before thrombolysis were enrolled. The presence of focal(More)
