The single-cell RNA-seq allows exploring the transcriptome for one cell at a time. By doing so, cellular regulation is pictured. One limitation dropout events phenomenon, where gene observed low or moderate expression level in but not detected another. Dropouts obscure legitimate biological heterogeneity leading to description of small fraction meaningful relations. We used stochastic approach ...

Dengue is the most important arboviral disease transmitted to humans. In our laboratory, we have been working on the standardization of the polymerase chain reaction (PCR) diagnosis of this disease. In this work, we compared five commercial kits regularly used on reverse-transcription polymerase chain reaction (RT-PCR) protocols: two Two-Step kits (SuperScript II RT/Super Mix kit and reverse tr...

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...

Hop stunt viroid (HSVd), a significant pathogen of some hop cultivars, was detected for the first time in hops Australia. Plants were tested graft-transmissible pathogens prior to their use research trials. Upon observing symptoms indicative potential infection, RNA extracted and amplified using reverse transcription polymerase chain reaction (RT-PCR); HSVd identity confirmed by sequencing.

ObjectiveTo screen pregnant women at risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection during delivery using reverse-transcription polymerase chain reaction (RT-PCR) test and serum immunoglobulin (Ig) testing.MethodBetween March 31 st August 2020, consecutive admitted for labor in a single hospital were screened SARS-CoV-2 with nasopharyngeal RT-PCR swab tests detec...

Substrate properties of various morpholinonucleoside triphosphates in the reaction of DNA elongation catalyzed by DNA polymerase beta, reverse transcriptase of human immunodeficiency virus (HIV-1 RT), and reverse transcriptase of Moloney murine leukemia virus (M-MuLV RT) were compared. Morpholinonucleoside triphosphates were utilized by DNA polymerase beta and HIV-1 reverse transcriptase as sub...

A traditional single-stage reverse transcription-polymerase chain reaction (RT-PCR) procedure is effective in determining West Nile (WN) virus in avian tissue and infected cell cultures. However, the procedure lacks the sensitivity to detect WN virus in equine tissue. We describe an RT-nested PCR (RT-nPCR) procedure that identifies the North American strain of WN virus directly in equine and av...

Background: Sinonasal symptoms were usually reported to appear initially, yielding the important for early detection of coronavirus disease 2019 (COVID-19). This study was conducted retrospectively investigate detailed sinonasal manifestations and dynamic profile real-time reverse transcription polymerase chain reaction (RT-PCR) results severe acute respiratory syndrome 2 (SARS-CoV-2) in COVID-...

A sensitive reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay for human enterovirus 71 (EV71) and Coxsackievirus A16 (CVA16) infection was further evaluated. The one step reaction was performed in a single tube at 65 ̊C for 45 min for EV71 and 35 min for CVA16. The detection limits of RT-LAMP assays for both EV71 and CVA16 were 0.1 of a 50% tissue culture infective dos...
