The usefulness of reverse transcription loop‐mediated isothermal amplification (RT‐LAMP) for the rapid diagnosis of hepatitis C virus (HCV) RNA was evaluated. This assay showed higher sensitivities than that of nested RT‐PCR, with a detection limit of 600 IU mL−1, and no cross‐reactivity was observed with hepatitis A virus, hepatitis B virus and hepatitis E virus. Furthermore, 106 stored sera from...
Tight, integrated accelerometers are current interests in Micro-Opto-electro-Mechanical-Systems (MOEMS). An optical accelerometer based on a novel integrated optical resonator is proposed. The transmission spectra and the relation between the structure parameters and the device sensitivity are simulated. This ring resonator structure shows great potential to develop high sensitive accelerometers.
The pine wood nematode (PWN), Bursaphelenchus xylophilus, is a disastrous pathogen of the pine forests in East Asia and Europe. Plant quarantine is one of the most important ways to prevent its infection in current situation. A nested polymerase chain reaction (PCR) assay targeting the topoisomerse I gene has been developed to detect PWN in this study. To assess the specificity of the assay, 44 morphologically...
