The objective of this study was to establish the optimum protocol for the isolation and culture of porcine muscle satellite cells. Mononuclear muscle satellite cells are a kind of adult stem cell, which is located between the basal lamina and sarcolemma of muscle fibers and is the primary source of myogenic precursor cells in postnatal muscle. Muscle satellite cells are a useful model to investigate the mechanisms of muscle growth and development. Although the isolation and culture protocols of muscle satellite cells in some species (e.g. mouse) have been established successfully, the culture system for porcine muscle satellite cells is very limited. In this study, we optimized the isolation procedure of porcine muscle satellite cells and elaborated the isolation and culture process in detail. Furthermore, we characterized the porcine muscle satellite cells using the immunofluorecence. Our study provides a reference for the isolation of porcine muscle satellite cells and will be useful for studying the molecular mechanisms in these cells.

To overcome the capture-range problem in phase-diversity phase retrieval (PDPR), a geometricaloptics initial-estimate method is proposed to avoid a local minimum and to improve the accuracy of laser-wavefront measurement. We calculate the low-order aberrations through the geometrical-optics model, which is based on the two spot images in the propagation path of the laser, and provide it as a starting guess for the PDPR algorithm. Simulations show that this improves the accuracy of wavefront recovery by 62.17% compared to other initial values, and the iteration time with our method is reduced by 28.96%. That is, this approach can solve the capture-range problem.

Seven phenolic compounds (1-7) were isolated from the tubers of Gastrodia elata. Their structures were elucidated on the basis of MS and NMR spectral data. p-Ethoxymethyl phenyl-O-${\beta}$-D-glucoside (1) was proved to be a new compound, with N-(p-hydroxybenzyl)-adenosine (7) isolated from this plant for the first time. In this study, the protective effects of the six constituents (1-6) on PC12 cells against the cytotoxicity induced by KCI and glutamate were also investigated. The viability of the PC12 cells was significantly enhanced by pretreatment with the six phenolic constituents.
Numerical simulation and experiments of magnetic flux leakage inspection in pipeline steel

The magnetic flux leakage (MFL) method is currently the most commonly used pipeline inspection technique. In this paper, numerical simulation and experimental investigation on defect inspection in pipeline steel using MFL were carried out. In theoretical analysis, typical three-dimensional (3D) defects were accurately modeled and detailed MFL signals in the test surface were calculated by 3D finite element method (FEM). To confirm the 3D FEM results, different artificial defects were made and the MFL experiments were performed. The experimental study demonstrated that the results were agreement with the 3D FEM result. The results show that the 3D FEM is an effective analysis method for pipeline steel MFL inspection.

In our recent work (Ma et al., in Planta229(3):457–469, 2009a and 229(4):1077–1086, 2009b),two three-intron type III PKS genes, PcPKS1 and PcPKS2,were isolated from Polygonum cuspidatum Sieb. et Zucc. Phylogenetic and functional analyses revealed PcPKS1 is athree-intron chalcone synthase (CHS) gene, and PcPKS2 isfound to be a three-intron benzalacetone synthase (BAS)gene. The regular CHS encoded by a single intron genehave not been isolated and characterized from P. cuspidatum. In this work a further CHS with one intron (PcPKS3)and a stilbene synthase (STS) gene with three-intron(PcPKS5) were isolated and characterized by functionaland phylogenetic analyses. In comparison with PcPKS1, abifunctional enzyme with both CHS and BAS activity, theenzymatic product of recombinant PcPKS3 was naringenin,bis-noryangonin (BNY) and 4-coumaroyltriacetic acidlactone (CTAL) occurred as side products. The PcPKS5synthesized resveratrol and a trace amount of naringeninfrom p-coumaroyl-CoA. To our knowledge, PcPKS5 is thefirst reported three-intron STS gene in flowering plants. Inthis work, we speculated that this involved a possibleevolutionary route of plant-specific type III PKS superfamilyin P. cuspidatum.

In this work a further CHS with one intron (PcPKS3) and a stilbene synthase (STS) gene with three-intron (PcPKS5) were isolated and characterized by functional and phylogenetic analyses. In comparison with PcPKS1, a bifunctional enzyme with both CHS and BAS activity, the enzymatic product of recombinant PcPKS3 was naringenin, bis-noryangonin (BNY) and 4-coumaroyltriacetic acid lactone (CTAL) occurred as side products.

Their structures were determined by chemical analysis and spectral methods (IR, 1D and 2D NMR, HR-ESI-MS). Compounds 1-4 were exhibited various degrees of cytotoxicity in the human hepatoma cell line, HepG2. Compound 1 had the highest cytotoxic Potency, with an $IC_{50}$ value of 20.1 ${\mu}M$, by stimulating p53-mediated cell cycle arrest at the G1 to S phase transition, leading to apoptosis via activation of the caspase signaling pathway.
