Background: Enterovirus (EV) infections are one of the most common causes of aseptic meningitis in pediatrics. To diagnose EV meningitis, virus isolation in cell cultures is often time consuming and lacks sensitivity to be of clinical relevance. This makes the virus culture results difficult to interpret. The rapid detection of EVs in cerebrospinal fluid (CSF) by molecular diagnostic techniques...

Introduction Detection of RNA in cells is routinely performed by in vitro methods such as RT-PCR and fluorescent in situ hybridization (FISH). RTPCR quantifies gene expression of a cell population. FISH requires fixation of cells, thus unable to give a true picture of mRNA localization. Molecular beacons (MBs) are antisense oligonucleotide stem-loop probes that fluoresce upon hybridization with...

Abstract. The Real-Time Working Group (RTWG) of the International GNSS Service (IGS) is dedicated to providing high-quality data and high-accuracy products for Global Navigation Satellite System (GNSS) positioning, navigation, timing Earth observations. As one part real-time products, IGS combined Ionosphere Map (RT-GIM) has been generated by weighting RT-GIMs from ionosphere centers including ...

during 2010-2011, real-time pcr procedure was used to detecting fmdv rna on 147 epithelium samples from the field. in this survey, for real-time pcr from 3d gene segment as conserve region selected for tracking all of seven serotypes fmdv. the assay detected the viral rna in all serotypes of fmdv. the rrt-pcr specifically detected fmd virus in sample with greater sensitivity than our convention...

* Faculty of Information Technology, Rangsit University. Abstract With the rapidly increasing number of Thai text documents available in digital media and websites, it is important to find an efficient text indexing technique to facilitate search and retrieval. An efficient index would speed up the response time and improve the accessibility of the documents. Up to now, not much research in Tha...

Molecular methods are being increasingly applied to detect, quantify and study microbial populations in food or during food processes. Among these methods, PCR-based techniques have been the subject of considerable focus and ISO guidelines have been established for the detection of food-borne pathogens. More particularly, real-time quantitative PCR (qPCR) is considered as a method of choice for...

Mental chronometry is the measurement of cognitive speed. It is the actual time taken to process information of different types and degrees of complexity. The basic measurements are an individual’s response time (RT) to a visual or auditory stimulus that calls for a particular response, choice, or decision. Since at least the time of Sir Francis Galton (1822–1911), the father of differential ps...

background and aims: hepatitis c virus is one of the viral infections transmitted by blood transfusion. patients with thalassaemia frequently need blood transfusion and are in danger of hcv infection. in most cases of infection (85%) the virus evades the immune system and establishes a chronic infection that may lead to cirrhosis and liver carcinoma. liver is the main site of hcv replication hc...
