MicroRNA-34a (miR-34a) is a transcriptional target of p53 that is down-regulated in some cancer cell lines. We studied the expression, targets, and functional effects of miR-34a in brain tumor cells and human gliomas. Transfection of miR-34a down-regulated c-Met in human glioma and medulloblastoma cells and Notch-1, Notch-2, and CDK6 protein expressions in(More)
OBJECTIVE Glycemic variability is poorly studied in the nondiabetic individuals and newly diagnosed patients with type 2 diabetes. The aim of the study is to investigate the characteristics of glucose fluctuations in subjects with normal glucose tolerance (NGT), impaired glucose regulation (IGR) and newly diagnosed, drug-naïve type 2 diabetes mellitus(More)
We present a method to identify small molecule ligand binding sites and poses within a given protein crystal structure using GPU-accelerated Hamiltonian replica exchange molecular dynamics simulations. The Hamiltonians used vary from the physical end state of protein interacting with the ligand to an unphysical end state where the ligand does not interact(More)
PURPOSE The receptor tyrosine kinase (RTK) c-MET and its ligand hepatocyte growth factor (HGF) are deregulated and promote malignancy in cancer and brain tumors. Consequently, clinically applicable c-MET inhibitors have been developed. The purpose of this study was to investigate the not-well-known molecular determinants that predict responsiveness to c-MET(More)
We previously showed the involvement of the tyrosine kinase receptor c-Met in medulloblastoma malignancy. The nonreceptor tyrosine kinases focal adhesion kinase (FAK) and Pyk2 are key players in the progression of different cancers. However, their role in medulloblastoma malignancy is not well understood. In this study, using a protein array approach, we(More)
OBJECTIVE The use of autologous platelet-rich gel (APG) is a relatively new technology and a promising treatment method for infections, which is currently being used by a variety of surgical specialties. The mechanism of antibacterial effect of APG is not yet fully discovered. Subsequent evidence suggests that platelets have multiple functional attributes(More)
OBJECTIVE The aim of this preliminary study is to investigate contributions of basal glucose (BG) and postprandial glucose (PPG) increments to overall hyperglycemia in newly diagnosed patients with type 2 diabetes mellitus (T2DM). RESEARCH DESIGN AND METHODS We evaluated the relative contributions of BG and PPG to overall hyperglycemia in 59 newly(More)
BACKGROUND The variability of postprandial plasma glucose is an independent risk factor for diabetes. The type and amount of carbohydrate may be important determinants of glycemic control. The aim of the study was to compare the effects of different proportions of carbohydrate in breakfast on postprandial blood glucose fluctuations in impaired glucose(More)
The purpose of the study is to examine the safety and effectiveness of topical autologous platelet-rich gel (APG) application on facilitating the healing of diabetic chronic refractory cutaneous ulcers. The study was designed as a prospective, randomized controlled trial between January 1, 2007 and December 31, 2011. Eligible inpatients at the Diabetic Foot(More)
