Comparative analysis of whole-genome sequences of Streptococcus suis

The recent outbreak of Streptococcus suis in some districts of Sichuan Province in China has caused over 30 deaths and more than 200 infections in human be-ings[1]. Streptococcus suis is a Gram-positive, faculta-tively anaerobic bacterium, a peculiar path…     

A novel domain-based method for predicting the functional classes of proteins

Prediction of protein functions from known genomic sequences is an important mission of bioinformatics. One approach is to classify proteins into functional categories. We have therefore developed a method based on protein domain composition and the maximum likelihood estimation (MLE) algorithm to classify proteins according to functions. Using the Saccharomyces cerevisiae genome, we compared the effectiveness of the MLE approach with that of an intuitive and simple method. The MLE method outperformed the simple method, achieving an estimated specificity of 75.45 % and an estimated sensitivity of 40.26 %. These results indicate that domain is an important feature of proteins and is closely related to protein function.     

东莨菪碱在薄层色谱原位的傅立叶变换表面增强拉曼光谱研究

利用高效薄层色谱（ＴＬＣ）分离技术与表面增强拉曼散射技术（ＳＥＲＳ）的结合，获得了分析东莨菪碱成分的新方法．ＳＥＲＳ结果表明，在ＴＬＣ原位约８μｇ样品就可获得东莨菪碱分子的主要振动特征谱带．通过光谱检测揭示出ＳＥＲＳ与固体光谱的异同，并指明了东莨菪碱分子与银溶胶的吸附模式．ＴＬＣＳＥＲＳ使高效分离与指纹鉴定结合，可对化学成分进行高灵敏度检测

Biological networks to the analysis of microarray data

Microarray technology, which permits rapid and large-scale screening for patterns of gene expressions, usually generates a large amount of data. How to mine the biological meanings under these data is one of the main challenges in bioinformatics. Compared to the pure mathematical techniques, those methods incorporated with some prior biological knowledge generally bring better interpretations. Recently, a new analysis, in which the knowledge of biological networks such as metabolic network and protein interaction network is introduced, is widely applied to microarray data analysis. The microarray data analysis based on biological networks contains two main research aspects: identification of active components in biological networks and assessment of gene sets significance. In this paper, we briefly review the progress of these two categories of analyses, especially some representative methods.     

钩藤碱的TLC-FT-SERS研究

本文报道了应用表面增强技术将薄层色谱（ＴＬＣ）与傅立叶变换拉曼光谱（ＦＴ－Ｒａｍａｎ）联用,获得了中草药钩藤中的钩藤碱光谱研究的新方法。研究表明,在薄层原位２．５ｕｇ多心藤总碱,即可很好的分离出多心藤碱等多种钩藤生物碱。应用薄层原位表面增强（ＴＬＣ－ＦＴ－ＳＥＲＳ）技术,获得钩藤碱分子的特征振动谱带,进而阐述了样品分子在表面增强基底银胶表面的吸附模式,钩藤碱以分子中甲氧基Ｏ原子的孤电子对吸附于银晶     

菠菜色素的提取与分离
