BACKGROUND A single nucleotide polymorphism in the promoter region of -1607 bp of the human matrix metalloproteinase-1 (MMP-1) gene has been found to be associated with an increased risk of various inflammatory diseases and cancer metastasis. OBJECTIVES The present study aimed to examine the distribution of MMP-1 genotypes in a group of Chinese subjects(More)
OBJECTIVES Polymorphisms for toll-like receptor (TLR) 2 gene (Arg677Trp, Arg753Gln) and TLR4 gene (Asp299Gly, Thr399Ile) that are associated with impaired lipopolysaccharide (LPS) signal transduction have recently been described. The present study aimed to investigate the relationship between TLRs 2 and 4 gene polymorphisms and periodontitis in a Chinese(More)
Previous works have shown that Dynamic Time Warping (DTW) algorithm is a proper method of feature extraction for electromyography (EMG)-based handwriting recognition. In this paper, several modifications are proposed to improve the classification process and enhance recognition accuracy. A two-phase template making approach has been introduced to generate(More)
A novel class of 2-(2'-hydroxyphenyl)benzothiazole-based (HBT-based) excited-state intramolecular proton-transfer (ESIPT) compounds, N,N'-di[3-Hydroxy-4-(2'-benzothiazole)phenyl]isophthalic amide (DHIA) and N,N'-di[3-Hydroxy-4-(2'-benzothiazole)phenyl]5-tert-butyl-isophthalic amide (DHBIA) has been feasibly synthesized and the properties of their(More)
Our previous research has proved that baicalin can inhibit the expression of Matrix metalloproteinases (MMPs) in periodontal ligament cells (PDLC) by cell immunocytochemistry. Therefore, the purpose of this study was to address the effects of baicalin on the total protein amount and Collagen I mRNA expression in PDLC, and the regulatory effects on Matrix(More)
Supporting and enhancing the regeneration and stability of alveolar bone at dental implant sites is necessary to improve implant integration and stability. In this study chitosan/collagen scaffolds combined with adenoviruses expressing either bone morphogenetic protein 7 (BMP-7), platelet-derived growth factor B (PDGF-B), or a combination of both BMP-7 and(More)
BACKGROUND AND OBJECTIVE CypA is able to regulate inflammatory responses and MMPs production via interaction with its cell surface receptor, EMMPRIN. This study aimed to address the possible association of CypA with pathological inflammation and destruction of periodontal tissues, and whether CypA-EMMPRIN interaction exists in periodontitis. MATERIALS AND(More)
This study aimed to establish a model of synaptic plasticity by the activation of metabotropic glutamate receptor (mGluR) I in rat medial septal diagonal band (MSDB). Electrophysiological experiment was performed to record the theta frequency oscillation activities in rat MSDB slices. The data were recorded and analyzed with Spike 2 (CED, Cambridge, UK).(More)
This paper investigates the design optimization of an electrostatically actuated microcantilever resonator that operates in air. The nonlinear effects of electrostatic actuation and air damping make the structural dynamics modeling more complex. There is a need for an efficient way to simulate the system behavior so that the design can be more readily(More)
Baicalin is a flavonoid compound purified from the medicinal plant Scutellaria baicalensis Georgi and has been reported to possess anti-inflammatory activity through its ability to complex with chemokines and thus reduces the capacity of chemokines to bind and activate their receptors. In the present study, we investigated whether baicalin could block(More)
