Results showed that the 11 tested samples were PPRV positive by nested RT-PCR, of which 2 samples were genetically close to the X7443 strain (Nigeria 75/1) of lineage I, and 3 samples close to the strain AY560591 (Sungri96) of linage IV with 96.6%、97.3%、97.6% and 98% nucleotide sequence homogeneity respectively, based on partial sequencing of the F gene from 5 samples and complete sequencing of the N/M/F/H genes from one sample. This study suggested that there are at least 2 origins of PPRV in China.展开更多

The purpose of this study is to analyze the pharmaceutical sector of Bangladesh using the framework of PEST. This report brings to light the current state of the sector its progress and its problems. Through this study the researchers try to discuss the affect of various macro-economic factors of political, economic, social, and technological aspect on the industry and its related problems and prospects for the future.展开更多

In this study, a content analysis of news coverage appearing in Macao Daily between July 1, 2015 and December 31, 2015 was conducted. It also applied PEST method to carry out detailed analysis of the public’s opinions, aiming at gaining a better understanding of the current situation of tobacco control work in Macao and the challenges lay ahead. Moreover, we use KAP (Knowledge-Attitude-Practice) framework to propose further enhancement and improvement of government’s tobacco control work.展开更多
