Background: DNA hypermethylation and instability due to inactivation mutations in Ten–eleven translocation 2 (TET2) is a key biomarker of hematological malignancies. This study aims at characterizing two intronic noncanonical splice-site variants, c.3954+5_3954+8delGTTT c.3954+5G>A. Methods: We used silico prediction tools, reverse transcription (RT)-PCR, Sanger sequencing on blood/bone marrow-...

Background and Aims: Certification programs of plant propagating materials rely on faster, cheaper and more importantly sensitive and reliable methods for detection of systemic pathogens as indicated in national and/or international health standards of plant propagating materials. Reverse transcription-polymerase chain reaction (RT-PCR) has been documented as an alternative assay for certific...

DNA products generated from a region of the measles virus genome by three RNA reverse transcription and amplification methods were cloned and sequenced, and the results were compared in order to evaluate the methods' relative fidelities. The methods were: (i) reverse transcription followed by a nested polymerase chain reaction (RT-nPCR), (ii) a combined RT-PCR using rTth polymerase and (iii) nu...

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...

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 ...

Vascular endothelial growth factor (VEGF)-induced angiogenesis contributes to inflammatory bone resorption in humans. Widely documented antagonists include antibiotics and non-steroidal anti-inflammatory drugs (NSAIDs). The purpose of this study was investigate the effect these on proangiogenic VEGF levels periradicular lesions. Periapical tissue biopsies were obtained from 42 patients with chr...

canine distemper virus (cdv) is the cause of canine distemper (cd) which is a severe and highly contagious disease in dogs. in the present study, a duplex reverse transcription polymerase chain reaction (rt-pcr) method was developed for the detection and differentiation of wild-type and vaccine strains of cdv. four primers were designed to detect and discriminate the two viruses by generating 6...

We have adapted our previously described poliovirus diagnostic reverse transcription-PCR (RT-PCR) assays to a real-time RT-PCR (rRT-PCR) format. Our highly specific assays and rRT-PCR reagents are designed for use in the WHO Global Polio Laboratory Network for rapid and large-scale identification of poliovirus field isolates.

background and aims: canine distemper (cd) is a deadly infectious disease of canidae family. cd is a multi-systemic viral disease and is specified by wide range of clinical symptoms. the manifestations are not always indicative of cd, therefore a laboratory confirmation is necessary for suspected cases. materials and methods: different clinical specimens of 19 cd suspected unvaccinated dogs wer...
