Operon is a fundamental unit of transcription which is usually used to understand gene regulations and functions in entire genomes. Detecting operon experimentally is difficult and time-consuming, thus many bioinformatics algorithms have been proposed to predict operon. In this paper, we use an improved discrete genetic algorithm based on quantum theory for operon prediction. It is simpler and more...
We have developed a simple, rapid, selective, and reproducible method for the quality control of traditional Chinese medicinal preparations. In this study, we used LC/MS/MS to simultaneously identify and quantify five marker compounds – matrine, oxymatrine, ferulic acid, mangiferin, and glycyrrhizin – in preparations of Shiau-feng-saan and Dang-guei-nian-tong-tang. The calibration curves for the five...
