TSARG7 is a novel member of the acyltransferase family since its sequence possesses the highly conserved phosphate acyltransferase （PlsC） domain existing in all acyltransferase-like proteins. The porcine TSARG7 had been identified by cloning in silico but had not been confirmed experimentally. The full-length mRNA of porcine TSARG7 gene was sequenced and two splice variants were discovered. The full-length cDNA of TSARG7 variant 1 was 2 513 bp and variant 2 was 2 634 bp. The putative porcine TSARG7 proteins, which were located in the cytoplasm, encoded 458 and 456 amino acids, respectively. Real-time PCR analysis showed that TSARG7 gene was expressed in various tissues, but at different levels. The expression levels of this gene were higher in the skeletal muscle, heart, and testis than that in other tissues, suggesting that the TSARG7 gene played a role in procine skeletal muscle, heart, and testis functions.

针对现有访问控制模型不能完全满足协同设计系统访问控制需求的实际,在对基于消息通信协同设计特性进行分析研究的基础上,以协同设计系统的访问控制实现为目标,以基于角色访问控制(RBAC)模型为基础,提出一种面向协同设计的消息驱动访问控制模型(MDACM).该模型应用消息实体作为权限表达,以消息实体与过滤规则相结合的方法,通过静态的配置方式实现动态的资源控制,解决了协同设计系统分布性和动态性带来的安全隐患问题.此外,通过流程控制基作用于消息实体使模型能够支持协同设计系统的工作流程管理,并通过应用示例说明模型的有效性.

In this study, an antimicrobial component（RTCI） was purified from the skin of Rana temporaria chensinensis, David. Antimicrobial activities of RTCI against clinical multi-drug resistant bacterial strains, including Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureaus, Klebsiella oxytoca, Klebsiella pneumoniae, Enterococcus fae-calis, and Proteus mirabilis, were measured in vitro by means of minimal inhibitory concentration and time-kill studies. The results indicate that RTCI could inhibit the growth of these bacteria at a proper concentration and suggest that RT-CI shows a better antimicrobial activity to Gram-negative bacterial strains than to Gram-positive bacterial strains.

Objective To introduce a novel Cobb protractor and assess its reliability and rapidity for measuring Cobb angle in scoliosis patients. Methods The novel Cobb protractor had two endplate markers. A measurement was performed just to align the two markers to each endplate of the curve. The Cobb angle on the posteroanterior radiographs of 24 patients clinically diagnosed with adolescent idiopathic scoliosis was measured by three orthopedic surgeons with both standard Cobb method and the new technique, and the time of measurement was recorded. Intraclass correlation coefficients(ICCs) were calculated to assess the reliability of the new method. Results The time for a measurement with the new tool was approximately 10 seconds less than the time that used to finish a measurement with the standard method(P<0.05). The overall mean Cobb angle for the major curve of the 24 patients was 47.8°. The mean overall intraobserver and interobserver ICC was 0.971 and 0.971 for the Cobb method group, while the overall intraobserver ICC and the interobserver was 0.985 and 0.979 for the new tool group. Conclusions The novel Cobb protractor could perform quick measurement and measure almost all forms of radiographs. The Cobb protractor might be an ideal instrument to measure the Cobb angle.

This paper describes the key issues of high-speed brushless permanent magnet motor design, such as rotor design, stator design, and determination of the main dimensions, and the overall design process was given. In this paper, a two-pole three-phase high-speed brushless PM （permanent magnet） motor with ratings air-gap length and stator slot number on the motor performance of 7.5 kW, 30,000 rpm is designed, and the effect of the different was analyzed. The results show that larger number of stator slot decreases the rotor loss and the rotor torque ripple. Larger air-gap length decreases the rotor loss.

A chaotic synchronized system of two coupled skew tent maps is discussed in this paper. The locally and globallyriddled basins of the chaotic synchronized attractor are studied. It is found that there is a novel phenomenon in thelocal-global riddling bifurcation of the attractive basin of the chaotic synchronized attractor in some specific couplingintervals. The coupling parameter corresponding to the locally riddled basin has a single value which is embeddedin the coupling parameter interval corresponding to the globally riddled basin, just like a breakpoint. Also, there isno relation between this phenomenon and the form of the chaotic synchronized attractor. This phenomenon is foundanalytically. We also try to explain it in a physical sense. It may be that the chaotic synchronized attractor is in thecritical state, as it is infinitely close to the boundary of its attractive basin. We conjecture that this isolated criticalvalue phenomenon will be common in a system with a chaotic attractor in the critical state, in spite of the system beingdiscrete or differential.
