| 1 | Novel way to research nonlinear feedback shift register显示文摘In this paper,we regard the nonlinear feedback shift register(NLFSR)as a special Boolean network,and use semi-tensor product of matrices and matrix expression of logic to convert the dynamic equations of NLFSR into an equivalent algebraic equation.Based on them,we propose some novel and generalized techniques to study NLFSR.First,a general method is presented to solve an open problem of how to obtain the properties(the number of fixed points and the cycles with different lengths)of the state sequences produced by a given NLFSR,i.e.,the analysis of a given NLFSR.We then show how to construct all 22n-(l-n)/22n-lshortest n-stage feedback shift registers(nFSR)and at least 22n-(l-n)-1/22n-l-1shortest n-stage nonlinear feedback shift registers(nNLFSR)which can output a given nonperiodic/periodic sequence with length l.Besides,we propose two novel cycles joining algorithms for the construction of full-length nNLFSR.Finally,two algorithms are presented to construct 22n-2-1different full-length nNLFSRs,respectively. | ZHAO DaWei PENG HaiPeng LI LiXiang HUI SiLi YANG YiXian | 2014 | Science China(Information Sciences)2014，57，9： | 7 |
| 2 | Remineralization of enamel caries by an amelogenin-derived peptide and fluoride in vitro显示文摘Dental caries is one of the most common oral diseases in the world.This study was tantamount to investigate the combinatory effects of an amelogenin-derived peptide(called QP5)and fluoride on the remineralization of artificial enamel caries.The peptide QP5 was synthesized and characterized,and the binding capability of the peptide on hydroxyapatite(HA)and demineralized tooth enamel surface was analysed.Then,the mineralization function of the peptide and fluoride was studied through the spontaneous mineralization testing and remineralization on enamel caries in vitro.First,the novel peptide QP5 could bind on the hydroxyapatite and demineralized tooth enamel surfaces.Second,QP5 can transitorily stabilize the formation of amorphous calcium phosphate and direct the transformation into hydroxyapatite crystals alone and in combination with fluoride.In addition,compared to blocks treated by peptide QP5 alone or fluoride,the sample blocks showed significantly higher surface microhardness,lower mineral loss and shallower lesion depth after treatment with a combination of QP5 and fluoride at high or low concentrations.The peptide QP5 could control the crystallization of hydroxyapatite,and combinatory application of peptide QP5 and fluoride had a potential synergistic effect on the remineralization of enamel caries. | Longjiang Ding Sili Han Kun Wang Sainan Zheng Wenyue Zheng Xiu Peng Yumei Niu Wei Li Linglin Zhang | 2020 | Regenerative Biomaterials2020，7，3： | 6 |

| 6 | Evaluating the potential of an amelogenin-derived peptide in tertiary dentin formation显示文摘Several novel biomaterials have been developed for dental pulp capping by inducing tertiary dentin formation.The aim of this study was to evaluate the effect of QP5,an amelogenin-based peptide,on the mineralization of dental pulp cells(DPCs)in vitro and in vivo.The cell viability of human DPCs(hDPCs)after treatment with QP5 was determined using the Cell Counting Kit-8(CCK-8).Migration of hDPCs was assessed using scratch assays,and the pro-mineralization effect was determined using alkaline phosphatase(ALP)staining,alizarin red staining and the expression of mineralization-related genes and proteins.The results showed that QP5 had little effect on the cell viability,and significantly enhanced the migration capability of hDPCs.QP5 promoted the formation of mineralized nodules,and upregulated the activity of ALP,the expression of mRNA and proteins of mineralization-related genes.A pulp capping model in rats was generated to investigate the biological effect of QP5.The results of micro-computed tomography and haematoxylin and eosin staining indicated that the formation of tertiary dentin in QP5-capping groups was more prominent than that in the negative control group.These results indicated the potential of QP5 as a pulp therapy agent. | Xiu Peng Sili Han Kun Wang Longjiang Ding Zhenqi Liu Linglin Zhang | 2021 | Regenerative Biomaterials2021，8，2： | 0 |
