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)
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)
Brain-specifi c anion transporter BSAT1 extracellular fragment (451-557) cDNA was cloned in a vector for prokaryotic expression, a producer E. coli strain was obtained, and recombinant extracellular fragment BSAT1451-557 was purifi ed and used for immunization of BALB/c mice. Splenic cells from mice with verifi ed immune response were used for hybridoma(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)
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)
Variation of microsatellite loci Gmo8, Gmo-G12, Gmo-G18, Gmo19, PGmo32, Gmo34, and Gmo35 is investigated in Kildin cod Gadus morhua kildinensis. The investigated loci are characterized by a low level of variation: five loci are represented by two-allele systems and three loci are monomorphic. Mean value of heterozygosity calculated by all investigated loci(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)
Using the AGP*, PGI-1*, PGI-2*, LDH*, IDH*, and PGM* allozyme markers, the differentiation of cod groups during the spawning period in Baltic Sea was evaluated. It was demonstrated that cod samples from the eastern and western parts of Baltic Sea (being statistically significantly different from the cod samples from the Norwegian Sea, Barents Sea, and the(More)
