Based on the structure and function analysis of hirudin, a potent thrombin inhibitor, and some platelet aggregation inhibitors, which contain the recognition sequence argglyasp as their functional motif, two chimeric antithrombotic molecules were designed by introducing rgd sequence to hirudin cterminus. these chimera genes were constructed by pcr and inserted into the expression vector pet21a, the constructs were confirmed by restriction enzyme digestion and dna sequence analysis. these recombinant plasmids were transformed into
經限制酶消化和dna序列分析，證明兩種重組質粒與設計完全一致。由於rgd -水蛭素嵌合基因上游連接了金黃色葡萄球菌蛋白a spa的信號肽序列，在iptg誘導下兩種嵌合分子都獲得了分泌表達，表達產物主要集中在細胞周質空間。To get in vivo evidences that apoplast calmodulin con 1d regulate plant growth and development process, a chimeric secretion form of calmodulin binding peptide, which contains a signal peptide, a calmodulin binding domain and a c - myc epitope was constructed. the chimeric gene was introduced into arabidopsis. it was expected that the overexpression of this chimeric protein could be secreted into cell wall and bound to apoplast calmodulin, which could reduce the apoplast calmoduin concentration to make an apoplast camodulin " antisense " plant. by observing the potential phenotype change of apoplast calmodulin " antisense " plant, the in vivo function of apoplast calmodulin on plant growth and developmental process could be speculated
但這些多是採用生理學手段和藥理學方法而得出的體外（ invitro ）實驗結果，為了取得質外體cam在植物生長發育過程中發揮重要作用的invivo實驗證據，根據動物中的一些研究方法，本實驗設計並構建了帶有信號肽、 cam結合肽（ can小肽） 、 epitope （ c - myc ）融合基因的載體，並將融合基因通過真空滲入法轉入擬南芥，預期過表達的融合蛋白將會被分泌到細胞外並與質外體cam相結合，這樣就會抑制質外體cam的功能，從而可以構建質外體cam的「反義」植株，通過觀察質外體cam 「反義植株」的表型改變，就可以推斷質外體cam在植物生長發育過程中的功能。Immunohistochemistry method was used to observe the temporal and spatial expression of nmdar2, signal molecules, skeleton proteins and connexins in son neurons and glias ( astrocytes and microglias ). radioimmunoassay was used to detect vasopressin ( vp ) content in plasma before and after hyperosmotic stimulation. ultrastructure between activated son astrocytes and neurons was observed by double immune - electron - microscopic staining method
應用免疫組織化學方法光鏡下觀察高滲刺激后，大鼠視上核膠質細胞（星形膠質細胞和小膠質細胞）受體（ nmdar2 ） 、信號分子、骨架蛋白及縫隙連接蛋白的表達的時空變化；應用放免測定檢測高滲刺激前後血漿中vp含量。Most current algorithms only work well in special conditions, because of the abnormity of signals in the real world. now, the research in the ica arises much passion and the ica has brought about many applications. the primary results the writer has got are as the following : after a whiting process, it is a key to find an orthogonal matrix to throw away the high - order redundant information between components
由於現實生活中信號十分不規則，目前提出的演算法大多隻能針對某類信號分離，鑒于目前在ica方面極大的研究熱情和強大的背景支持，作者對ica離線演算法做了一定研究，主要內容和工作包括如下: ica問題經過白化處理后，尋找去除高階相關的正交矩陣成為問題關鍵，而正交矩陣具有特殊的空間結構，組成它的每個列向量可視作rn中單位超球表面上一點，當這些點彼此垂直時，整體就組成一個正交矩陣。The current gpr data analyzing method for pavement thickness can only give the acceptable results for new asphalt concrete pavement, but for aged asphalt concrete pavement and cement concrete pavement, the accuracy is not satisfactory because of the theoretic modeling and data acquisition difficulties. the study on pavement compaction, moisture content and asphalt content is under exploration and the program for processing gpr data based on rigorous theoretic model can not be found in literature
由於理論模型及信號採集等方面的困難，現行路面雷達厚度分析方法僅對新鋪瀝青混凝土路面有相對較好的檢測精度，而對舊瀝青混凝土路面和水泥混凝土路面的檢測精度卻不能令人滿意，對路面其它技術指標如壓實度、含水量以及瀝青含量的研究還處于探索階段，建立在嚴密理論模型基礎上的數據分析軟體系統尚處于空白狀態。After the induction of iptg, the extracellular proteins of pet22asg / bl21 ( de3 ) plyss showed blue when treated with gus staining solution ; but the extracellular proteins of ck : bl21 ( de3 ) plyss showed no color change with the same treat. these results verified the function of secreting protein by grb - ast signal peptide
將表達載體pet22asg導入表達宿主菌e . colibl21 （ de3 ） plyss ，經iptg誘導表達，其胞外蛋白以gus染色液處理顯藍色；而對照空宿主菌bl21 （ de3 ） plyss誘導表達后，經同樣的處理，顏色無明顯變化，這初步證實了ast信號肽具有一定的分泌蛋白的功能。This paper applies wavelet theory to process data analysis, mostly focusing on signal de - noise and data compression. the main contributions of this thesis are as follows : 1 ) as discussion and experiment of de - noise method for removing white, noise from pulp thickness signal, a method was developed by utilizing the different characters of evolution of the wavelet transform maximum across scale of efficient signal and noise
本文所作的工作如下： 1 ）利用小波變換下有效信號和噪聲在多尺度空間中不同的模極大值傳播特性，給出了一種去除紙漿濃度檢測信號中的白噪聲的演算法，編制了相應的程序，作為對紙漿濃度檢測信號去噪方法的初步探討和嘗試。These results showed these proteins have a high degree of similarity ; they are basic and cysteine - rich proteins with a signal peptide and a common pattern of eight cysteines that engaged in four disulphide bridges holding together four a helices and stabilizing the structural fold. a hydrophobic central cavity in which can occupied by lipids is found between the four helices. however, it has been difficult to draw any conclusions about the in vivo activity of nsltps from their lipid binding properties because it is unknown which ligands, if any, are bound to nsltps in vivo
不同物種的非特異性轉移蛋白具有很高同源性，它們是堿性的富含半胱氨酸的蛋白質，在n端有一個信號序列， 8個保守的半胱氨酸殘基能形成4個二疏鍵以維持蛋白的空間結構，推測在其空間結構的中心形成了一個能容納脂類物質的洞穴，但在體內還不知道nsltp的配體包括哪些物質，對于nsltp能否在體內能夠結合併轉運脂類還沒有明確的定論。Specification for harmonized system of quality assessment for electronic components - semiconductor discrete devices - blank detail specification - signal diodes, switching diodes and controlled avalanche diodes
