ABSTRACT
Matrix-assisted laser desorption/ionization time-of-flight imaging mass spectrometry (MALDI-TOF-IMS) can analysis unknown compounds in sections and obtain molecule imaging by scanning biological tissue sections,which has become a powerful tool for the research of biomarker,lipid distribution and drug metabolism,etc.This article reviews the application of this technique in protein identification,clinical application,drug discovery,lipid research and brain injury.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the influence of the surveillance system and preventive measurements on the control of severe acute respiratory syndrome (SARS) in a university in Guangdong Province.</p><p><b>METHODS</b>A university with more than thirty thousand undergraduates, staff and their relatives was retrospectively studied, from which information regarding the status of epidemic, organization of leadership, disease control strategies and measures were collected and analyzed.</p><p><b>RESULTS</b>The construction of the surveillance system in such a model as "individual-dormitory/home-class/unite-faculty and institute-university" largely contributed to the achievement of the goals of low incidence, no secondary, no epidemic, and no death. A series of control measures benefited the early diagnosis, effective isolation, prevention, and treatment of SARS control.</p><p><b>CONCLUSION</b>SARS could be effectively controlled in university only if strict surveillance system is built up, and all-round preventions, including early isolation of both confirmed or suspected cases and close contacted persons, are carried out.</p>
