The disease caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in Wuhan, China, December 2019, has rapidly spread worldwide. SARS-CoV-2 is usually detected via real-time reverse-transcription polymerase chain reaction (RT-PCR). However, the increase specimen load institutions/hospitals necessitates a simpler detection system. Here, we present an ultra-rapid, RT-PCR assay for...

background and aims: accurate and rapid diagnosis is necessary for effective control and prevention of foot-and-mouth disease (fmd). in present study, was evaluated real time reverse transcription-polymerase chain reaction (rrt-pcr) assay along with diagnostic routine methods for the detection of all seven serotypes of fmd virus (fmdv), namely o, c, a, sat1, 2, 3 and asia 1 in biological sample...

In a visual search experiment, the subject must find a target item hidden in a display of other items, and their performance is measured by their reaction time (RT). Here I look at how visual search reaction times are correlated with past reaction times. Target-absent RTs (i.e. RTs to displays that have no target) are strongly correlated with past target-absent RTs and, treated as a time series...

The present study was aimed at characterizing the cognitive deficits caused by the degeneration of nigrostriatal dopamine (DA) pathways by using the additive factor logic [Sternberg, S. (1969) Acta Psychol., 30, 276-315], a powerful reaction time (RT) method developed in humans and recently introduced in the rat [Courtiere, A., Hardouin, J., Hasbroucq, T., Possamai, C.-A. & Vidal, F. (2000) Beh...

In a 3 X 2 X 2 factoral experiment, 12 subjects carried out a choice reaction task with reaction time (RT) and movement time (MT) as response measures. Independent variables were drug treatment (amphetamine, barbiturate, placebo), visual stimulus degradation and S-R compatibility. Visual stimulus degradation and S-R compatibility showed additive effect on the RT, but did not affect the MT. This...

INTRODUCTION The diagnosis of pleural tuberculosis requires an invasive and time-consuming reference method. Polymerase chain reaction (PCR) is rapid, but validation in pleural tuberculosis is still weak. OBJECTIVE To establish the operating characteristics of real-time polymerase chain reaction (RT-PCR) hybridization probes for the diagnosis of pleural tuberculosis. METHODS The validity of...

The real-time quantitative polymerase chain reaction (rtqPCR) has overcome the limitations of conventional, time-consuming quantitative PCR strategies and is maturing into a routine tool to quantify gene expression levels, following reverse transcription (RT) of mRNA into complementary DNA (cDNA). Expression pro®ling with single-cell resolution is highly desirable, in particular for complex tis...

The study investigated squeezing reaction time (RT) in response to a visual cue during rhythmic voluntary breathing at 0.6 Hz paced by a metronome, breath holding, or at rest in 13 healthy subjects. Rhythmic voluntary breathing slowed down RT, only in the expiratory phase with accompanied changes in the length of respiratory phases, while breath-holding reduced RT. The prolonged RT during volun...
