BACKGROUND The relative efficacy of induction chemotherapy (IC) followed by concurrent chemoradiotherapy (CCRT) versus IC followed by radiotherapy (RT) alone in locoregionally advanced NPC remains unclear. METHODS A total of 877 patients with locally advanced NPC who underwent IC/CCRT or IC/RT at four institutions in China between January 2004 and December 2010 were retrospectively assessed. ...

Successful disease management requires a rapid and sensitive diagnosis method that can recognize early infection even before the manifestation of its clinical signs. The only available field diagnostic tests for foot-and-mouth disease (FMD) are lateral flow devices, commonly known as chromatographic strips. Low sensitivity and inability to detect FMD virus (FMDV) at the serotype level are limit...

Collection of mosquitoes and testing for vector-borne viruses is a key surveillance activity that directly influences the vector control efforts of public health agencies, including determining when and where to apply insecticides. Vector control districts in California routinely monitor for three human pathogenic viruses including West Nile virus (WNV), Western equine encephalitis virus (WEEV)...

Studies describing reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay-based infection control strategies (LAMP-based ICSs) for coronavirus disease 2019 (COVID-19) are limited. We reviewed the medical records of cases in which RT-LAMP was performed. Standard ICSs and LAMP-based were implemented during study period. The intended to impose longer periods precautions (ICPs...

The COVID-19 pandemic has underscored the shortcomings in deployment of state-of-the-art diagnostics platforms. Although several polymerase chain reaction (PCR)-based techniques have been rapidly developed to meet growing testing needs, such often need samples collected through a swab, use RNA extraction kits, and expensive thermocyclers order successfully perform test. Isothermal amplification...

A rapid, cost-effective diagnostic test for the detection of acute HIV-1 infection is highly desired. Isothermal amplification techniques, such as reverse-transcription loop-mediated isothermal amplification (RT-LAMP), exhibit characteristics that are ideal for the development of a rapid nucleic acid amplification test (NAAT) because they are quick, easy to perform and do not require complex, d...

The development and validation of a one-step, real-time, and quantitative dengue virus serotype-specific reverse transcription-loop-mediated isothermal amplification (RT-LAMP) assay targeting the 3' noncoding region for the rapid detection and differentiation of dengue virus serotypes are reported. The RT-LAMP assay is very simple and rapid, wherein the amplification can be obtained in 30 min u...

The SARS-CoV-2 pandemic has forced all countries worldwide to rapidly develop and implement widespread testing control manage the Coronavirus Disease 2019 (COVID-19). reverse-transcription (RT)-qPCR is gold standard molecular diagnostic method for COVID-19, mostly in automated platforms. These systems are accurate effective, but also costly, time-consuming, high-technological, infrastructure-de...

The standardization and validation of a one-step, single-tube accelerated quantitative reverse transcription-loop-mediated isothermal amplification (RT-LAMP) assay is reported for rapid and real-time detection of Japanese encephalitis virus (JEV). The RT-LAMP assay reported in this study is very simple and rapid; the amplification can be obtained in 30 min under isothermal conditions at 63 degr...
