The use of Dextrostix Reflectance Meter (DRM)* to measure blood glucose has been reported recently. The method has proved to be simnple, rapid, and accurate, and to correlate well with various reference methods (Mazzaferri et al., 1970; Jarret, Keen, and Hardwick, 1970; Schersten, 1971; Deckert and Futtrup, 1971). The handiness of the DRM seemed to make it an excellent tool in the diagnosis of ...

A considerable number of deletions of variable size and position that involve the B-globin gene complex on chromosome 1 1 are associated with the clinical entities of hereditary persistence of fetal hemoglobin (HPFH) and a@ thalassemia. Specific deletions appear to be associated with consistent phenotypes and some are known to be recurrent. To facilitate the molecular diagnosis of uncharacte...

RNA amplification by nucleic acid sequence-based amplification (NASBA) was used to detect serotype specific dengue viruses in artificially-infected female Aedes mosquitoes, in comparison with RT-PCR technique. NASBA could detect dengue virus serotype 2 and 4 below 0.1 PFU, which was more sensitive than RT-PCR, but this technique was as sensitive as RTPCR when detecting dengue virus serotype 1 a...

n engl j med 364;2 nejm.org january 13, 2011 182 stem cells is the standard by which their pluripotent potential is evaluated.1-3 We believe that the intended application of human induced pluripotent stem-cell lines should determine the evaluation method. The issue of pluripotency becomes important for studies of the functional mechanism of reprogramming. However, a reproducible and rapid metho...

Rapid, sensitive, and selective detection of live pathogens remains a key priority for quality control risk assessment. While conventional methods often require complicated workflows, costly reagents, lab equipment, are time-consuming, rendering them inadequate field testing low-resource settings. Increased attention has been drawn to developing alternative low-cost rapid detect on-site in diff...
