Reaction time (RT) has been used to discriminate individuals with brain damage from controls, but little is known about the relationship between RT and neuropsychological (NP) tests. This relationship was examined 3 ways. First, the mean, median, and SD scores of simple and choice RT for 213 referrals were used as potential predictors of NP impairment in discriminant analyses; cross-validation ...

background and objectives : each year, enteroviruses infect millions of people and cause different diseases. the agents are usually detected using cell culture. rd (rhabdomyosarcoma) and l20b (l cells) are among the recommended cells by the world health organisation (who) for this purpose. even though cell culture is the most common method used in diagnosing enteroviruses in stool specimens, th...

Rapid diagnosis of acute promyelocytic leukemia (APL) with promyelocytic leukemia-retinoic acid receptor alpha (PML-RARa) contributes to a highly effective therapy with all-trans retinoic acid (ATRA). Real-time quantitative reverse transcription-polymerase chain reaction (RT-qPCR) is a valuable tool to diagnose APL with PML-RARa. However, a single RT-qPCR analysis, which is laborious and costly...

To behave more efficiently the human brain must anticipate future events with different probabilities and prepare appropriate responses. Previous studies demonstrated that participants react faster to more probable stimuli. It has been shown that this effect in reaction time reduction is related to the response preparation process. However it is still unknown what the minimum difference in stim...

Human enterovirus 71 (EV71) is the major causative agent of hand, foot, and mouth disease (HFMD) worldwide and has been associated with neurological complications which resulted in fatalities during recent outbreak in Asia pacific region. A direct reverse transcription loop-mediated isothermal amplification (direct RT-LAMP) assay using heat-treated samples without RNA extraction was developed a...

Rapid and sensitive detection of prions is important in managing prion diseases. The real-time quaking-induced conversion (RT-QuIC) assay for prion seeding activity has been applied to many prion diseases and provides for specific antemortem diagnostic testing. We evaluated RT-QuIC's long-term consistency and varied multiple reaction parameters. Repeated assays of a single scrapie sample using ...

Real Time Polymerase Chain Reaction also known as quantitative PCR (q-PCR) is a widely used tool in microbial ecology to quantify gene abundances of taxonomic and functional groups in environmental samples. Used in combination with a reverse transcriptase reaction (RT-q-PCR), it can also be employed to quantify gene transcripts. q-PCR makes use of highly sensitive fluorescent detection chemistr...

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 study of neural coding is complicated by the almost infinite number of possible codes: which of the constellation of codes is used by the brain? The approach adopted here is t o examine the validity of predictions about behaviour made from a simple model incorporating neural codes. The visual information acquisition hypothesis [1-3] predicts that neural activity should reveal a longer delay...

We evaluated the commercially available Rapid Analyte Measurement Platform (RAMP) West Nile virus (WNV) antigen detection test for sensitivity and consistency with real-time reverse transcriptase polymerase chain reaction (RT-PCR) confirmation testing. Panels of samples consisting of WNV-spiked mosquito pools and negative control pools were sent to 20 mosquito abatement districts (MADs) that pr...
