The diagnostic utility of two PCR systems and three PCR detection methods for hepatitis C virus (HCV) RNA was evaluated in serum samples. A nested PCR was considered the reference assay and was compared with two single-step PCR methods: the first is based on the detection of PCR products by liquid hybridization with a 32P-end-labeled probe, and the second is the Roche Amplicor colorimetric assa...
One-step triplex PCR/RT-PCR to detect canine distemper virus, canine parvovirus and canine kobuvirus
Real time PCR (RT-PCR) detection method is the widely used for COVID-19 virus detection. This includes sample collection in viral transport medium (VTM), RNA extraction followed by of using fluorescence dye-based system RT-PCR machine. Several studies have demonstrated a new which replaces step simple involving DTT and Proteinase-K heat treatment. ICMR few other governing bodies approved such p...
A LightCycler and two TaqMan real-time PCR assays were evaluated against an older PCR with liquid-phase hybridization method for the detection of enterovirus RNA in 74 patient samples. The two-step LightCycler and the two-step TaqMan formats correlated well with each other (r(2) = 0.90) and were equally sensitive compared to the liquid-phase hybridization method, whereas the one-step recombinan...
Contamination of seafood with salmonellae is a major public health concern. Detection of Salmonella by standard culture methods is time consuming. In this study, an enrichment culture step prior to polymerase chain reaction (PCR) was applied to detect 284 bp fragment of Salmonella invA in comparison with the conventional culture method in 100 shrimp samples collected from four different shrimp ...
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
We apply the dressing method to a string solution given by a static string wrapped around the equator of a three-sphere and find that the result is the single spike solution recently discussed in the literature. Further application of the method allows the construction of solutions with multiple spikes. In particular we construct the solution describing the scattering of two single spikes and c...
