HEp-2细胞MPM-2磷蛋白的蛋白质组学分析

MPM-2磷蛋白家族成员在有丝分裂进程中起着重要作用．为了从MPM-2磷蛋白家族层面入手研究细胞周期调控中磷蛋白的重要作用，以人上皮样喉癌细胞株HEp-2为细胞模型，运用双向电泳、免疫印迹以及质谱技术等蛋白质组学的方法对其细胞抽提物中的部分MPM-2磷蛋白进行了分析鉴定，初步确定了乙二醛酶(GlyoxalaseⅠ)、真核翻译起始因子(eIF4B)以及核质蛋白NPM等MPM-2特异识别的细胞磷蛋白，这将有助于进一步研究MPM2磷蛋白家族成员在细胞周期调控中的重要作用．     

￣（45）Ca跨膜流动测定技术用于中药钙拮抗作用的研究

应用￣（４５）Ｃａ跨膜流动测定技术研究钙拮抗剂ｖｅｒａｐａｍｉｌ、中药西红花（ＣｒｏｃｕｓＳａｔｉｖｕｓＬ．）、“地奥心血康”（ＤＡＸＸＫ）、川红花（ＣａｒｔｈａｍｕｓｔｉｎｃｔｏｒｉｕｓＬ．）及银杏叶（ＧｉｎｋｇｏｂｉｌｏｂａＬ．）等对大鼠主动脉￣（４５）Ｃａ跨膜内流的作用，以确定其对细胞膜Ｃａ￣（２＋）通道影响。实验结果表明：西红花、川红花、ＤＡＸＸＫ对平滑肌细胞膜上电压依赖Ｃａ￣（２＋）通道（ＰＤＣ）和受体操纵Ｃａ￣（２＋）通道（ＲＯＣ）都有阻滞作用，并以西红花的阻滞作用最强；而银杏叶对细胞膜Ｃａ￣（２＋）通道无阻滞作用。

Intramammary expression and therapeutic effect of a human lysozyme-expressing vector for treating bovine mastitis

To develop a gene therapy strategy for treating bovine mastitis, a new mammary-specific vector containing human lysozyme (hLYZ) cDNA and kanamycin resistance gene was constructed for intramammary expression and clinical studies. After one time acupuncture or intracisternal infusion of healthy cows with 400 μg of the p215C3LYZ vector, over 2.0 μg/ml of rhLYZ could be detected by enzymatic assay for about 3 weeks in the milk samples. Western blotting showed that rhLYZ secreted into milk samples from the vector-injected cows had molecular weight similar to that of the natural hLYZ in human colostrums. Twenty days after the primary injection, the quarters were re-injected with the same vector by quarter acupuncture and even higher concentrations of rhLYZ could be detected. Indirect competitive ELISA of milk samples showed that the vector injection did not induce detectable humoral immune response against hLYZ. Clinical studies showed that twice acupuncture of quarters with the p215C3LYZ vector had overt therapeutic effect on clinical and subclinical mastitis previously treated with antibiotics, including disappearance of clinical symptoms and relatively high microbiological cure rates. These data provide a solid rationale for using the vector to develop gene therapy for treating bovine mastitis.

Lyapunov稳定性逆定理的另一种证明

Lyapunov方法是研究非线性控制问题的重要手段,而Lyapunov稳定性逆定理又是应用此方法的主要定理,但其证明却非常烦琐.利用直接取指数函数的方法,简化了Lyapunov稳定性逆定理中关键函数G的构造,给出了Lyapunov稳定性逆定理的另一种简单的证明方法.     

Researching on quadrature conversion structures For an UWB demonstrative receiver

1. INTRODUCTION As the development of technologies of digital signal processing and integrated circuits, the structure of wireless communication system has been improved. Many schemes for software defined radio (SDR) systems have been developed since 1995, and they can be divided into five tiers of solutions according to their developing history and their definitions[1]. The five tiers are conventional hardware-implemented scheme; software-controlled radio scheme; SDR, that implements m…
