mTORC1 promotes cell growth in response to nutrients and growth factors. Insulin activates mTORC1 through the PI3K-Akt pathway, which inhibits the TSC1-TSC2-TBC1D7 complex (the TSC complex) to turn on Rheb, an essential activator of mTORC1. However, the mechanistic basis of how this pathway integrates with nutrient-sensing pathways is unknown. We(More)
BACKGROUND The aim of our study was to examine the feasibility of allogeneic uterine transplantation in a large animal model. METHODS We performed heterotopic uterine transplants in genetically defined mini-pigs. Immunosuppression was tacrolimus administered intravenously for the first 12 days posttransplantation followed by oral cyclosporine maintenance(More)
To examine the effects of erythromycin on rhinovirus (RV) infection in airway epithelium, primary cultures of human tracheal epithelial cells were infected with the RV major subgroup, RV14, and the minor subgroup, RV2. Infection was confirmed by increases in viral RNA of the infected cells and viral titers of the supernatants. RV14 upregulated the(More)
In this study, we examined the biological action of IL-17 on human non-small cell lung cancer (NSCLC). Although IL-17 had no direct effect on the in vitro growth rate of NSCLC, IL-17 selectively augmented the secretion of an array of angiogenic CXC chemokines, including CXCL1, CXCL5, CXCL6, and CXCL8 but not angiostatic chemokines, by three different NSCLC(More)
BACKGROUND AND OBJECTIVES The clear delineation between tumor and normal tissue is ideal for real-time surgical navigation imaging. We present a novel indocyanine green (ICG) fluorescence imaging technique to visualize hepatocellular carcinoma (HCC). METHODS Ten patients with solitary HCC underwent hepatectomy between February and September 2007 at Osaka(More)
Because there is no effective treatment for this retinal degeneration, potential application of cell-based therapy has attracted considerable attention. Several investigations support that bone marrow mesenchymal stem cells (MSCs) can be used for a broad spectrum of indications. Bone marrow MSCs exert their therapeutic effect in part by secreting trophic(More)
OBJECTIVE To evaluate both the feasibility and efficacy of our combined therapy, which consisted of preoperative chemoradiation, surgery, and postoperative liver perfusion chemotherapy (LPC) for patients with T3 (extended beyond the pancreatic confines) cancer of the pancreas. SUMMARY BACKGROUND DATA Because of the high incidence of local recurrence and(More)
The control of gene transfection in the body is a core issue in gene therapy. Photochemical internalization is a technology that allows light-induced delivery of DNA, drugs or other biological factors directly inside cells. Usually it requires that a photosensitizer be added to the drug-delivery system to photochemically destabilize the endosomal membrane.(More)
OBJECTIVES In the current study, we have evaluated the clinical and immunological responses in patients with advanced pancreatic carcinoma who received dendritic cell (DC)-based immunotherapy in combination with gemcitabine and/or S-1. METHODS Dendritic cell-based immunotherapy (DC vaccine alone or DC vaccine plus lymphokine-activated killer [LAK] cell(More)
BACKGROUND Intensive oral care can reduce the incidence of pneumonia in elderly nursing home patients, but the mechanism is unknown. OBJECTIVE To explore the effects of intensive oral care on impaired cough reflex sensitivity, which is a known risk factor of aspiration pneumonia. METHODS Cough reflex sensitivity to citric acid was measured in elderly(More)
