The purpose of this study has been to investigate the possible effects of the normal joint cavity environment on chondrocytic differentiation of bone-marrow-derived mesenchymal stem cells (MSCs). Autologous bone marrow was aspirated from the iliac crest of male sheep. MSCs were purified, expanded, and labeled with the fluorescent dye PKH26. Labeled MSCs(More)
Lingual squamous cell carcinoma is common and the survival rate is relatively low. The invasion of cancer cells from the primary tumour into the surrounding tissue is an early step in the process of metastasis and urokinase-type plasminogen activator receptor (uPAR) is a vital mediator of cellular migration in some carcinomas. By binding urokinase-type(More)
BACKGROUND Patients with mucoepidermoid carcinoma exhibit poor long-term prognosis because of the lack of therapeutic strategies that effectively block tumor progression. We have previously characterized the Ms cells as a highly metastatic mucoepidermoid carcinoma cell line that expresses high levels of transforming growth factor β1 (TGF-β1). Here, we(More)
OBJECTIVE Recurrent aphthous ulceration is the most common oral mucosal lesion and may be associated with many systemic diseases. Topical corticosteroids are used frequently for recurrent aphthous ulceration; however, the number of high-quality clinical experiments available is insufficient, and no reports exist on the blood level of corticosteroids after(More)
A novel fast SAR image change detection method is presented in this paper. Based on a Bayesian approach, the prior information that speckles follow the Nakagami distribution is incorporated into the difference image (DI) generation process. The new DI performs much better than the familiar log ratio (LR) DI as well as the cumulant based Kullback-Leibler(More)
BACKGROUND Multidrug resistance-related protein 1 (MRP1/ABCC1) and multidrug resistance protein 1 (MDR1/P-glycoprotein/ABCB1) are both membrane-bound drug transporters. In contrast to MDR1, MRP1 also transports glutathione (GSH) and drugs conjugated to GSH. Due to its extraordinary transport properties, MRP1/ABCC1 contributes to several physiological(More)
The purpose of this study was to examine age-related changes in the tomographic characteristics of the temporomandibular joints (TMJ) of patients with temporomandibular dysfunction (TMD). 174 patietns with TMD from 12–76 years old were divided into six groups by age. Bilateral TMJs of the patients were examined by TMJ tomography, and 91 joints were also(More)
OBJECTIVE The purpose of this study was to evaluate the effects of the exogenous phosphatase and tensin homology deleted on chromosome 10 (PTEN) gene on in vitro growth of the highly metastatic mucoepidemoid carcinoma cell line M3SP2. METHODS The growth of the exogenous PTEN transfected mucoepidemoid carcinoma cells M3SP2-PTEN gene was studied by(More)
