In order to develop an artificial intelligence and computer-aided diagnosis system that assists neuroradiologists to interpret magnetic resonance (MR) images. This paper employed Hu moment invariant (HMI) as the brain image features, and we proposed a novel predator-prey particle swarm optimization (PP-PSO) algorithm used to train the weights of(More)
UNLABELLED WHAT IS ALREADY KNOWN ABOUT THE SUBJECT: * Concomitant use of different drugs may yield excessive risk for adverse drug reactions and it is a challenging task to do surveillance on the safety profile of the interaction between different drugs. * Currently, several methods are used by pharmacoepidemiologists and statisticians to detect possible(More)
PURPOSE We developed a computerized system for signal detection in spontaneous reporting system (SRS) of Shanghai. Data acquisition, data mining could be carried out automatically and the process of data preprocessing and cleaning could be facilitated. This system was expected to detect signals from SRS after drug licensing with minimum patient exposure. (More)
PURPOSE To give an overview of the current status including problems and efforts about pharmacovigilance in Traditional Chinese Medicine (TCM) safety surveillance. METHODS It is based on literature review and publicly available data in China. RESULTS TCM led to several adverse drug reactions (ADRs) during the past few years and pharmacovigilance about(More)
Studies of the relationship between male infertility and CYP1A1 polymorphisms are inconclusive. To drive a more precise estimation, we performed a meta-analysis based on 1060 cases and 1225 controls from 7 published case-control studies. PubMed and CNKI literature search were conducted to identify all eligible studies investigating such a relationship.(More)
1. INTRODUCTION Microelectrodes and ultramicroelectrodes (UMEs) have been the subjects of intense studies in electrochemical sensing 1À9 and in electrical energy storage and conversion. 10À21 Microelectrodes and ultramicroelectrodes refer to electrodes with characteristic sizes less than 25 μm. 3À6 These electrodes have been used extensively in different(More)
