BACKGROUND Early and rapid detection of dengue virus (DENV) infection during the febrile period is crucial for proper patient management and prevention of disease spread. An easy to perform and highly sensitive method is needed for routine implementation especially in the resource-limited rural healthcare settings where dengue is endemic. METHODS A single-tube reverse transcription-loop-media...

We have previously demonstrated that a DNA vaccine encoding HIV-p55gag in association with the lysosomal associated membrane protein-1 (LAMP-1) elicited a greater Gag-specific immune response, in comparison to a DNA encoding the native gag. In vitro studies have also demonstrated that LAMP/Gag was highly expressed and was present in MHCII containing compartments in transfected cells. In this st...

Infectious bursal disease (IBD) is an immunosuppressive, acute and highly contagious illness of growing-poultry stock infected with infectious bursal disease virus (IBDV). It is common in Pakistan, causing potential economic losses throughout the year. The objective of the study is to propose a rapid, sensitive and specific diagnostic tool, and compare it with existing commonly used reverse tra...

The aim of this study was to produce a sensitive, simple and rapid diagnostic method for the detection of foot-and-mouth disease virus (FMDV) in suspected cases of FMD, a one-step single-tube method of reverse transcription loop-mediated isothermal polymerase amplification (RT-LAMP). A set of six common primers was designed to target the highly conserved region of the RNA polymerase 3Dpol gene ...

The lysosome-associated membrane proteins (LAMP), found in the outer membrane of lysosomes and also in a multilaminar compartment that contains major histocompatibility complex class II (MHC II) proteins, are directed to their localization by a cytoplasmic carboxyl-terminal sequence. Our studies of the immune response to LAMP-targeted proteins has led to the application of a HIV-1 gp160/LAMP ch...

School-to-career (STC) initiatives aim to help students transition to productive adult careers either directly from secondary school or via post-secondary training and education. To date, however, few studies have tracked important educational and employment outcomes that occur post-high school graduation. Employing a comparative longitudinal design, this study tracked the progress of graduates...

The northern root-knot nematode (Meloidogyne hapla) is a damaging nematode that has caused serious economic losses worldwide. In the present study, a sensitive, simple and rapid method was developed for detection of M. hapla in infested plant roots by combining a Flinders Technology Associates (FTA) card with loop-mediated isothermal amplification (LAMP). The specific primers of LAMP were desig...

ABSTRACT Although T8 fluorescent lamp life is typically rated at 20,000 hours, it can significantly vary depending on the ballast product. The current industry practice for testing fluorescent lamp life requires these lamps to be subjected to 3-hours on/20-minutes off cycle, which is also known as the standard cycle for life testing. This method requires over 2 years of testing, which is expens...

methods genomic dna of cultured s. agalactiae was prepared and loop-mediated isothermal amplification (lamp) primers were designed based on the camp gene in bacteria. the optimum primer set was selected based on the reaction speed and specificity. the reaction result was monitored visually. the sensitivity and specificity of the lamp method were evaluated and compared with polymerase chain reac...

We developed a useful method for the detection of rubella virus genome RNA by reverse transcription loop-mediated isothermal amplification (RT-LAMP) and compared the sensitivity of RT-LAMP with that of other virological tests: reverse transcription-PCR (RT-PCR) and virus isolation. The rubella virus genome was amplified by RT-LAMP from clinical isolates obtained between 1987 and 2004 with simil...
