The extracellular matrix provides a framework for cell adhesion, supports cell movement, and serves to compartmentalize tissues into functional units. Fibronectin is a core component of many extracellular matrices where it regulates a variety of cell activities through direct interactions with cell surface integrin receptors. Fibronectin is synthesized by(More)
— It has been shown that the dynamic environment around the mobile robot can be efficiently and robustly represented by the Bayesian occupancy filter (BOF) [1]. In the BOF framework, the environment is decomposed into a grid-based representation in which both the occupancy and the velocity distributions are estimated for each grid cell. In such a(More)
Given the growing number of arthritis patients and the limitations of current treatments, there is great urgency to explore cartilage substitutes by tissue engineering. In this study, we developed a novel decellularization method for menisci to prepare acellular extracellular matrix (ECM) scaffolds with minimal adverse effects on the ECM. Among all the acid(More)
AIM To investigate the prognostic role of thymidylate synthase (TS) and thymidine phosphorylase (TP) mRNA levels in T3 or T4 gastric cancer treated with 5-fluorouracil-based adjuvant chemotherapy. METHODS Fifty-one patients with T3 or T4 gastric cancer received systemic 5-fluorouracil-based adjuvant chemotherapy, and intratumoral expression of TS and TP(More)
PURPOSE Our purpose was to perform a systematic review and meta-analysis of the clinical outcomes of single-row versus double-row repair. METHODS An electronic search was performed using PubMed, EMBASE, and the Cochrane Library up to September 30, 2012. Studies that met the inclusion and exclusion criteria were assessed for quality of methodology. The(More)
Environmental signals from the extracellular matrix (ECM) are transmitted by cell surface receptors that connect to the actin cytoskeleton and to multiple intracellular signaling pathways. To dissect how the ECM regulates cell functions, we are using a three-dimensional (3D) fibrin-fibronectin matrix, resembling the wound provisional matrix. Fibroblasts(More)
It has been proposed that the topoisomerase II (TOP2)beta-DNA covalent complex arrests transcription and triggers 26S proteasome-mediated degradation of TOP2beta. It is unclear whether the initial trigger for proteasomal degradation is due to DNA damage or transcriptional arrest. In the current study we show that the TOP2 catalytic inhibitor(More)
This work characterized the metabolism disorders of acute liver failure (ALF) induced by carbon tetrachloride (CCl(4)) in a mouse model with different dosage of intoxication (100, 500 and 1000 mg/kg). Metabolic profiles of mice plasma were detected by gas chromatography/mass spectrometry (GC/MS) after chemical derivatization. Here an effective(More)
A simple, rapid and efficient capillary electrophoresis-mass spectrometry (CE-MS) method was developed to analyze urinary nucleosides for the first time. The composition of CE buffer and MS parameters were systematically optimized. The optimum buffer was 150 mM acetic acid containing 15% methanol and 15% ethanol. The optimum MS parameters were: methanol(More)
We investigate the problems of multiclass cancer classification with gene selection from gene expression data. Two different constructed multiclass classifiers with gene selection are proposed, which are fuzzy support vector machine (FSVM) with gene selection and binary classification tree based on SVM with gene selection. Using F test and recursive feature(More)
