We analyze the statistical behavior of signals in nonlinear circuits with delayed feedback in the presence of external Markovian noise. For the special class of circuits with intense phase mixing we develop an approach for the computation of the probability distributions and multitime correlation functions based on the random phase approximation. Both(More)
In this study, a rapid quantitative method using TaqMan-based real-time reverse transcription-polymerase chain reaction (qPCR-RT) has been developed for estimating the titers of measles, mumps and rubella (MMR) viruses in infected cell culture supernatants. The qPCR-RT assay was demonstrated to be a specific, sensitive, efficient and reproducible method.(More)
The nucleotide sequences of the replication origin regions of plasmids ColA-CA31 and ColD-CA23 were obtained. Analysis of the nucleotide sequences showed a high degree of homology of these regions with the plasmid ColE1 region responsible for its autonomous replication. In the ColA and ColD regions involved in the regulation of replication, sites have been(More)
The role of hepatitis E (HE) in sporadic morbidity at an endemic territory (Southern Uzbekistan) and the incidence of anti-HEV in different populations of a nonendemic region (Russia) were evaluated. Antibodies to HEV were detected in 22.1% of patients with acute HE, including mixed infections (+ HA or HB), in the Dekhkanabad district of Kashkadarya region(More)
A statistical theory for the evolution of radiation in a cavity excited by a partially coherent signal is constructed based on a simple theoretical model for a ring cavity with a nonlinear element, leading to a difference equation with a rapidly oscillating exponential. It is shown that mixing, being the cause of the onset of deterministic autostochastic(More)
Live attenuated vaccine is used for vaccination. The temperature-sensitive (ts) phenotype is characteristic for almost all vaccinal rubella strains. The acquisition of the temperature-sensitive phenotype during adaptation to cold is strongly correlated with attenuation of the wild-type virus. Nevertheless, the molecular mechanisms of rubella virus(More)
AIM Evaluate resolution and diagnostic significance of real-time multiplex PCR (MP RT-PCR) as a platform for group A rotavirus G/P genotyping test-systems. MATERIALS AND METHODS Primer and DNA probe construction for an experimental test-system based on MP RT-PCR was carried out by using specialized PC programs and sequence databases GenBank NCBI, EMBL(More)
AIM To study antiviral activity of metabolites of spore-forming strain "Pashkov" of B. pumilus on the model of enterovirus infection in vitro. MATERIALS AND METHODS B. pumilus strain "Pashkov" isolated from environment and identified by common methods. Cell cultures: Vero-6, Vero-ECC, and Vero-E6. Enteroviruses: type 1 poliovirus, Coxsackie B virus (1-6),(More)
