Quorum sensing (QS) is an intercellular signaling and gene regulatory mechanism, which is implicated in bacterial pathogenicity and food spoilage. Therefore, blocking bacterial QS system may prevent QS-controlled phenotypes responsible for food spoilage. In the present study, we aimed to investigate the anti-biofilm and quorum sensing inhibitory potentials of Rosa rugosatea polyphenol (RTP) extract, which is rich in polyphenols (87.52%) and flavonoids (61.03%). The RTP specifically inhibited QS-controlled violacein production in Chromobacterium violaceum 026 with 87.56% reduction without significantly affecting its growth. Moreover, RTP exhibited inhibition in swarming motility (84.90% and 78.03%) and biofilm formation (67.02% and 72.90%) of Escherichia coli K-12 and Pseudomonas aeruginosa PAO1 in a concentration-dependent manner, respectively. These findings strongly suggest that RTP potentially could be developed as a new QS inhibitor and/or anti-biofilm agent to enhance the shelf life and increase food safety. © 2014 Elsevier Ltd.

In this article, the notion of orthogonal nonseparable four-dimensional wavelet packets, which is the generalization of orthogonal univariate wavelet packets, is introduced. A new approach for constructing them is presented by iteration method. The orthogonality properties of four-dimensional wavelet packets are discussed. Three orthogonality formulas concerning these wavelet packets are estabished. © 2010 Trans Tech Publications.

In this paper, a path planning method based on adaptive genetic algorithm for mobile robot is proposed, this method uses the specialized genetic operators and adjusted adaptively the parameters to plan path for mobile robot. In the adaptive genetic algorithm, the probabilities of crossover and mutation (Pc and Pm) are varied depending on the fitness values of the solutions, we use adaptively varying and to optimal path. Experimental results show the feasibility and effectiveness of the algorithm in path planning for mobile robot. Copyright © 2011 Binary Information Press.

Objective: To prepare an O/W ginseng saponins-based nanoemulsion and investigate its amplified immune response. Method: The formulation of ginseng saponins-based nanoemulsion was optimized via the range of nanoemulsion zone in phase diagrams and the solubility of ginseng saponins. Its physicochemical properties were investigated, including morphology, particle size distribution, pH, viscosity and stability. Ginseng saponins-based nanoemulsion as adjuvant was co-administrated with a model antigen ovalbumin (OVA) in mice. Two weeks after the boosting, the serum levels of OVA-specific antibody and its isotypes were determined. Result: The optimized ginseng saponins-based nanoemulsion formulation consisted of ginseng saponins, IPM, Cremophor RH 40, glycerol and water (with the weight ratio of 2:4:17.8:17.8:58.4), which was a light yellow fluid. The shape of droplets was spherical under transmission electron microscopy with an average diameter of 72.20 run and a polydispersity index of 0.052. The viscosity and pH value of it were 4.20s and 6.02, respectively. And it showed good stability. When co-administered with OVA, no obvious side effects were observed in the mice immunized with ginseng saponin-based nanoemulsion. The serum levels of IgG, IgG1 and IgG2a antibody in the group of ginseng saponin-based nanoemulsion immunized mice was significantly increased compared to the groups of OVA and the saline solution of ginseng saponin. Compared with the adjuvant aluminium hydroxide, the serum levels of IgG and IgG1 antibodys in the groups of ginseng saponins-based nanoemulsion had no significant difference, but the level of IgG2a was obviously higher. Conclusion; ginseng saponin-based nanoemulsion could amplify the Th1 and Th2 immune responses, and can be used as the vaccine adjuvant.

Mechanical engineering is a discipline of engineering that applies the principles of physics and materials science for analysis, design, manufacturing, and maintenance of mechanical systems. In this work, the notion of matrix-valued multiresolution analysis of space L2 (Rn, Cs×s) is introduced. A method for constructing orthogonal matrix-valued ternary wavelet packs is developed and their properties are discussed by means of time-frequency analysis method, matrix theory and functional analysis method. Three orthogonality formulas concerning these wavelet packets are provided. Finally, new orthonormal wavelet pack bases of space L2 (Rn,Cs×s) are obtained by constructing a series of subspaces of orthogonal matrix-valued wavelet packets. © (2013) Trans Tech Publications, Switzerland.

Firstly the function of principal component analysis (PCA)and back propagation(BP) neural network are analyzed in this paper, the fusion method of PCA and BP neural network is proposed for face representation and recognition. Experiments are done on ORL face databases and compare the average recognition rate and training time. Experimental results show that the method achieves the higher recognition accuracy than PCA and BP neural network alone, and Shorten the learning time of the network. © 2011 IEEE.

Oxymatrine (OMT), a water-soluble drug, has a very low oral bioavailability because of its low membrane permeability and its biotransformation in the gastrointestinal tract. Formulated as an oxymatrine-phospholipid complex (OMT-PLC) can improve the lipid solubility and effectiveness of OMT. The purpose of this study was to explore the utility of the combination of a microemulsion and an OMT-PLC as a topical delivery vehicle for enhancing the absorption and efficacy of OMT. The solubility of OMT-PLC was determined and phase diagrams of microemulsions were constructed. Various microemulsion formulations were developed and characterized by their physicochemical properties, and their in vitro and in vivo permeability through skin. An optimal microemulsion (ME4), which presented as spherical droplets and consisted of 10.0% OMT-PLC, 8.0% isopropyl myristate, 30.0% Cremophor RH40/polyethylene glycol 400 (1:1) and 52.0% water, was selected. It possessed an average droplet size of 32.4 nm, a low viscosity of 113.7 mPa • s, and a high cloud point of 88°C. Compared to the control solution, ME4 provided better skin permeability in vitro and a higher retention ratio of OMT in skin in vivo. Moreover, ME4 significantly enhanced the antiproliferative activity of OMT on scar fibroblasts. These results indicate that the combination of a microemulsion and a phospholipid complex represents an effective vehicle for topical delivery of OMT.
