The emergence of commercial wireless devices based on ultra-wideband radio technology (UWB-RT) is widely awaited and anticipated. UWB-RT is not only applicable to communications, imaging and ranging, it also promises to alleviate the problem of increasingly scarce spectrum resources while enabling new wireless applications and business opportunities. These prospects have caught the early attent...

In an RT experiment, subjects were asked to respond with minimal responses to prerecorded dialogs and a manipulated version of these dialogs that contained only intonation and pause information. Response delays and, especially, variances were higher to the impoverished, intonation only, stimuli than to the original recordings. It was also found that intonation only utterances ending in a mid-fr...

BACKGROUND The reverse transcription (RT) of RNA to cDNA is a necessary first step for numerous research and molecular diagnostic applications. Although RT efficiency is known to be variable, little attention has been paid to the practical implications of that variability. METHODS We investigated the reproducibility of the RT step with commercial reverse transcriptases and RNA samples of vari...

A quantitative and rapid detection method for rotavirus in water samples was developed using immunomagnetic separation combined with quantitative reverse transcription-polymerase chain reaction (IMS-RT-qPCR). Magnetic beads coated with antibodies against representative group A rotavirus were used to capture and purify intact rotavirus particles in both artificial and real environmental water sa...

This application note describes how the Agilent 2100 bioanalyzer can be used in combination with Standardized RT (StaRT)-PCR reagents from Gene Express National Enterprises (G.E.N.E.), Inc. (Huntsville, AL, USA) to obtain highly reproducible, standardized gene expression measurement with RT-PCR. The internal standards used in StaRT-PCR control for variable loading of PCR products into electroph...

In biological research the analysis of gene expression levels in cells and tissues can be a powerful tool to gain insights into biological processes. For this, quantitative RT-PCR (RT-qPCR) is a popular method that often involve the use of constitutively expressed endogenous reference (or 'housekeeping') gene for normalization of data. Thus, it is essential to use reference genes that have been...

PURPOSE This aims of this study are to establish an ultra-rapid quantitative reverse transcription-PCR (RT-PCR) protocol that enables the diagnosis of i.p. cancer spread during operation, to reveal the mechanisms of peritoneal metastasis from non-serosa-invasive gastric carcinoma, and to evaluate the effect of the extensive intraoperative peritoneal lavage (EIPL) using the ultra-rapid quantitat...
