Pacific herring, Clupea pallasii, have recently colonised the northeast Atlantic and Arctic Oceans in the early Holocene. In a relatively short evolutionary time, the herring formed a community with a complex population structure. Previous genetic studies based on morphological, allozyme and mitochondrial DNA data have supported the existence of two herring(More)
Variability of cod spawning and feeding schools from Kandalaksha Bay of the White Sea, was examined at six allozyme and eight microsatellite loci. The degree of genetic differentiation at allozyme loci constituted θ = 0.36% [95% bootstrap interval 0.0458; 0.6743]. The differentiation estimates obtained using microsatellite markers were higher, θ = 1.33%(More)
An analysis of genetic variation is made according to four allozyme loci of reproductive (spawning) groups of oligovertebrate herring Clupea pallasii collected in various bays of the White Sea and the south-eastern part of the Barents Sea in 1995–2002. The temporal stability of genetic characteristics during several years is shown. The analysis of genetic(More)
The genetic diversity among spawning groups of herring from different parts of the White Sea was assessed using ten microsatellite loci. All loci were polymorphic with the expected heterozygosity estimates varying in the range of 12.7–94.1% (mean was 59.5%). The degree of genetic differentiation displayed by White Sea herring was statistically significant(More)
A strategy of “customer-centricity” as well as topical models of customer-centric companies is described. Propositions of effective social network (SN) technology application for various business aspects in such companies are suggested. Recommendations for theoretical description, analysis, modeling of customer-centric SN and also for their monitoring with(More)
The genetic variations among spawning groups of herrings from different spawning grounds of the northwestern part of the Sea of Okhotsk was assessed using ten microsatellite loci. All loci were polymorphic with the expected heterozygosity estimates varying at different loci in the range of 0.7–95.0% (with a mean of 68.5%). The degree of genetic(More)
A reliable self-timed channel, based on a pipeline ring architecture, uses a special-purpose protocol with prioritised token access. The previous design of a channel adaptor was implemented by speed-independent circuits but without a strict proof of formal correctness of the protocol. Now we are planning to redesign the interface by means of recently(More)
Myelin oligodendrocyte glycoprotein (MOG) is a myelin-specific protein of the central nervous system (CNS). It is a member of the immunoglobulin superfamily. The contents of this protein in oligodendrogliocyte membrane is very low (approximately 0.1% total proteins). Functions of MOG are still unknown. It is considered that MOG is an autoantigen capable to(More)
Physico-chemical properties and biological role of myelin basic protein (MBP)--one of the main myelin membrane proteins are reviewed. The data on MBP phosphorylation, methylation, fatty acid acylation and on interaction with lipid molecules in the human and animals bodies are presented. Much attention has been paid to the discussion of the diagnostic and(More)
cDNA fragment encoding neuron-specific enolase was amplified from the cDNA library of human brain. Then the fragment was cloned for expression in E. coli using the vector pET28-a. High level of neuron-specific enolase expression was confirmed by SDS-PAAG electrophoresis and immunochemical identity by immunoblot analysis. The constructed producer strain is(More)
