Abstract
The external morphological, X-ray, and tomographic study of a frozen rodent mummy from the Upper Pleistocene Yedoma deposits on the Tirekhtyakh River (a Semyuelyakh River tributary, Abyi ulus, Republic of Sakha (Yakutia), Russia) showed its belonging to Lemmus sp. The radiocarbon age of the finding is 41 305-41 885 cal B.P. This is the first Pleistocene discovery of a frozen mummy of a genus Lemmus representative. In terms of the body and skull sizes, coat color, the lower incisor length, and the molar structure, the specimen studied is similar to the recent Lemmus sibiricus (Kerr, 1792). Comparison of the mitochondrial COB gene sequence with the DNA sequences presented in the GenBank database also testified to the maximum similarity with the Recent Siberian brown lemming.

Abstract
Transgenic strains of Drosophila melanogaster capable of expressing a cDNA fragment corresponding to open reading frame (ORF) of the gene for the German cockroach densonucleosis virus capsid protein VP2 (ORF VP2) in specific tissues and at a certain stage of development depending on the type of chosen driver strains (GAL-UAS system) were obtained. The ORF VP2 transcription was examined at the imago stage after crossing the obtained transgenic Drosophila with the driver line expressing the inducer protein (GAL4) under control of actin promoter (the ORF VP2 expression is induced in all tissues of the first-generation Drosophila). It was demonstrated that the greater part of transcribed foreign RNA was represented by three spliced variants in which RNA fragments either between nucleotides 137 and 353 or between nucleotides 609 and 1925 were excised; the third spliced variant was represented by RNA lacking both introns. Using the next-generation sequencing (NGS) technique, the proportion of unspliced form relative to spliced variants of the analyzed RNA was assessed. It was shown that the ratio of unspliced form to the identified spliced variants of the analyzed RNA was approximately 1:6. It is suggested that splicing of viral RNA foreign to Drosophila can be a sort of defense mechanism preventing the large-scale production of the capsid protein, potentially hazardous to the host organism.

Abstract
Molecular interactions between proteins redox partners (cytochromes Р450 3А4, 3А5 and cytochrome b5) within the monooxygenase system, which is known to be involved in drug biotransformation, were investigated. Human cytochromes Р450 3А4 and 3А5 (CYP3A4 and CYP3A5) form complexes with various cytochromes b5: the microsomal (b5mc) and mitochondrial (b5om) forms of this protein, as well as with 2 "chimeric" proteins, b5(om-mc), b5(mc-om). Kinetic constants and equilibrium dissociation constants were determined by the SPR biosensor. Essential distinction between CYP3A4 and CYP3A5 was only observed upon their interactions with cytochrome b5om. Electroanalytical characteristics of electrodes with immobilized hemoproteins were obtained. The electrochemical analysis of CYP3A4, CYP3A5, b5mc, b5om, b5(om-mc), and b5(mc-om) immobilized on screen printed graphite electrodes modified with membranous matrix revealed that these proteins have very close reduction potentials -0.435 -0.350 V (vs. Ag/AgCl). Cytochrome b5mc was shown to be capable of stimulating the electrocatalytic activity of CYP3A4 in the presence of its substrate testosterone.

Abstract
The intracellular localization of the fusion protein composed of green fluorescent protein (GFP) and one of the capsid proteins (namely VP1) of the German cockroach densovirus BgDV1 was investigated using the HeLa human cell culture. The intracellular localization of GFP was analyzed in a series of control experiments. Histochemical analysis with GFP antibodies showed that the fusion protein is localized exclusively inside the nucleus of cells because of the transitory expression of the corresponding vector constructions, whereas the GFP is located both in the nucleus and the cytoplasm. We can conclude that the signal of the nuclear localization of the capsid protein of the German cockroach densovirus is functionally active, not only within the cells of this insect but within the human cell culture as well. This observation extends the experimental possibilities for studying the genetic control of intracellular traffic of densovirus proteins.

Abstract
The intracellular localization of the regulatory proteins encoded by the genome of the densovirus of German cockroach was analyzed using western-blotting of nuclear and cytoplasmic extracts of the densovirus-infected passaging cells tissue culture BGE-2. Two of the three regulatory proteins, NS1 and NS3, were shown to possess mainly nuclear localization, while NS2 protein was distributed between the nucleus and cytoplasm. Data obtained provide new information necessary for prediction of the functions of densovirus regulatory proteins. Intracellular localization of NS3 protein was described for the densoviruses for the first time.

Abstract
Nucleotide sequences of intergenic spacer of ribosomal RNA gene cluster (rIGS) were identified in mosquitoes Culex modestus, Culex torrentium and Culex pipiens pallens. The level of interpopulation variability of the rIGS in the subspecies C. pipiens pipiens (form pipiens--mosquitoes that inhabit the open waters, and form molestus--mosquitoes that inhabit basements) living in Russia was estimated. No extensive repetitive sequences characteristic of the rIGS of all previously described species of mosquitoes were found within the rIGS of Culex mosquitoes. At the same time, evolutionarily conserved motifs and relatively short degenerate sequences of different classes of transposable elements, as well as multiple blocks of variable microsatellite repeats were identified. Our data demonstrated that the rIGS of Culex mosquitoes can be considered as a promising molecular marker for the analysis of population and phylogenetic relationships within this group of insects.

Abstract
The rDNA locus of insects and other arthropods contains non-LTR retrotransposons (retroposons) that are specifically inserted into 28S rRNA genes. The most frequent retroposons are R1 and R2, but the mechanism of insertion and the functions of these mobile elements have not been studied in detail. A clone containing a full-length R1 retroposon copy was islated from the cosmid library of Blattella germanica genes and sequenced. The amino acid sequences encoded by ORF1 of the R1 retroposon were subjected to bioinformatic analysis. It was found that ORF1 of this mobile element encodes a protein (ORF1p) belonging to the superfamily of zinc finger (CCHC) retroviral nucleocapsid proteins and contains two conserved RRM domains (RNA-recognizing motifs) identified on the basis of analysis of the secondary structure of this protein. The discovery of RRM domains in ORF1p of R1 retroposons can contribute to the understanding of the mechanisms of their retrotransposition. We revealed a coiled-coil motif in the N-terminal region of R1 ORF1p, which is similar to the coiled-coil domain involved in homo- or heteromultimerization of proteins and in protein-protein interactions. The domain organization of homologous Gag-like proteins of retroposons in some insects and fungi was found to be similar to the structure established by us for R1 ORF1p of B. germanica.

Abstract
The inheritance patterns of the 5'-truncated copies of R2 retroposons were analyzed in individual crosses of the German cockroach. The recombination level within the cluster of ribosomal RNA genes was determined. It was demonstrated that only the frequencies of individual variants of 5'-truncated retroposon copies are appropriate for population analysis rather than the patterns characterizing individual X chromosomes. The methodical approach used in the work is convenient for studying the genetic variation in ribosomal DNA multigene families.

Abstract
The results of quantitative PCR (qPCR) presented in the paper clearly demonstrate that the sixteen-fold genome reduction inCyclops kolensisduring chromatin diminution (from 15.3 pg to 0.98 pg) results in a dramatic decrease in ribosomal RNA gene copy numbers in the genome of a somatic cell line by more than two orders of magnitude. The results presented allow for the consideration of the chromatin diminution as a mechanism of rDNA copy number regulation.

Abstract
Using cosmid vector, a gene library of German cockroach Blattella germanica was constructed. From this library, clones containing full-length copies of two subfamilies of R1 retroposons were selected. Retroposons R1 of German cockroach belonging to different subfamilies were shown to be different in domain organization of the ORF2 C-terminal region. For the first time, retroposons transmembrane domains were identified in the sequences of R1. It was demonstrated that two retroposon R1 subfamilies of German cockroach arose as a result of intragenomic divergence rather than via horizontal transfer of alien mobile element into cockroach genome. The differences in domain organization appeared not as a result of saltatory recombination processes, but as a consequence of gradual mutation accumulation, which led to either degeneration, or to domain formation.

Abstract
This is the first report providing results on identification, cloning, and sequencing of extended fragments (5'-truncated copies) of R1 and R2 retrotransposons integrated into Blattella germanica genome. Comparative structural analysis of the received clones revealed two distinct subfamilies of R1 elements. However, all B. germanica R1 clones have two common features: poly(T) tails and similar target site duplications. Nucleotide structure and organization of five sequenced R2 fragments was similar. Analysis of R2 nucleotide sequences revealed typical deletions at the 3'end of target sites and lack of homopolynucleotides tails.

Abstract
Little information is available on genetic variation within and between populations of pest cockroaches. In this study, intraspecific HindIII polymorphism was investigated in the German cockroach, Blattella germanica (Linnaeus) (Dictyoptera, Blattaria: Blattellidae), using restriction fragment length polymorphisms (RFLP) of the non-transcribed spacer (NTS) region of ribosomal DNA (rDNA). Individual male insects were collected from infestations at three different pig farms. Each population was characterized by HindIII restriction fragment frequencies and haplotype (a particular X-chromosome pattern) frequencies. The inheritance of the X-chromosome HindIII rDNA patterns over 12 generations (3 years) follows Mendelian patterns, and the stability of this polymorphic marker indicates infrequent genetic recombination of variable sites. Although pairwise genetic distance measures were uncorrelated with geographical distance, the pattern of genetic differentiation of the three cockroach populations suggests that human-mediated transport of cockroaches is an important force in shaping the population genetic structure of cockroach infestations, at least at the regional scale of 10-100 km. Sequence variation in the ribosomal NTS is a useful marker, and RFLP of rDNA is a simple, robust and reproducible technique for differentiating recently diverged cockroach populations.

Abstract
A new DNA virus (Parvoviridae: Densovirinae, Densovirus) was isolated and purified from descendants of field-collected German cockroaches, Blattella germanica. Viral DNA and cockroach tissues infected with B. germanica densovirus (BgDNV) were examined by electron microscopy. Virus particles, about 20 nm in diameter, were observed both in the nucleus and in the cytoplasm of infected cells. Virus DNA proved to be a linear molecule of about 1.2 microm in length. BgDNV isolated from infected cockroaches infected successfully and could be maintained in BGE-2, a B. germanica cell line. The complete BgDNV genome was sequenced and analysed. Five open reading frames (ORFs) were detected in the 5335 nt sequence: two ORFS that were on one DNA strand encoded structural capsid proteins (69.7 and 24.8 kDa) and three ORFs that were on the other strand encoded non-structural proteins (60.2, 30.3 and 25.9 kDa). Three putative promoters and polyadenylation signals were identified. Structural analysis of the inverted terminal repeats revealed the presence of extended palindromes. The genome structure of BgDNV was compared with that of other members of the family Parvoviridae; the predicted amino acid sequences were aligned and subjected to phylogenetic analyses.

Abstract
Using polymerase chain reaction technique with primers flanking target sites of retrotransposons R1 and R2, integrated copies of these transposable elements were amplified in various cockroach species (Blattodea). It was shown that each species has a unique pattern of "5'-undertranscripts" with the definite set of amplified fragments of different lengths. Intraspecies polymorphism was revealed in analysis of German cockroach specimens obtained upon individual mating. This is the first report providing results of identifying, cloning, and sequencing extended fragments (5'-truncated copies) of Blatella germanica R1 and R2 retrotransposons. It may be assumed that patterns of 5'-truncated copies of R1 and R2 elements can be used as markers in population and phylogenetic studies. Moreover, cloned and sequenced fragments will be employed in our further studies for screening of the German cockroach genomic library in order to detect full-length copies in this class transposable elements.

Abstract
The polymorphism of nuclear ribosomal DNA has been studied in male German cockroaches. The RFLP analysis has been used to identify seven types of HindIII fragments, the variation of which may serve as the basis for the differentiation of laboratory strains with respect to some population indices, including the average number of fragments per animal (N), the proportion of polymorphic loci (P), and the average pairwise similarity (APS). The interpopulation variation (FST) calculated for nine haplotypes is 53.85%.

Abstract
Intergeneric, interspecific, and intraspecific genetic variation of the 310-bp 3'-end region of the mitochondrial gene of cytochrome oxidase I (COI) has been assessed in ladybirds (Coleoptera: Coccinnellidae). The phylogenetic distances between eight species of ladybirds have been determined. Mitochondrial DNA (mtDNA) nucleotide sequences have been compared in Adalia bipunctata L. differing in the elytron and pronotum colors that have been sampled from several geographically remote populations. The taxonomic statuses of two morphs from the genus Adalia, A. bipunctata bipunctata and A. bipunctata fasciatopunctata, have been identified.

The complete BgDNV genome was sequenced and analyzed. Five ORF were detected: two coded for structural capsid proteins and were on one DNA strand, and three coded for regulatory proteins and were on the other strand. Potential promoters and polyadenylation signals were identified. Structural analysis was performed for terminal inverted repeats containing extended palindromes. The genome structure of BgDNV was compared with that of other Parvoviridae.

Abstract
Species-specific characteristics of nuclear ribosomal DNA (rDNA) have been determined for the first time for six insect species of order Blattaria (Insecta, Dictyoptera) with the use of restriction analysis and Southern blotting. Probes containing highly conserved fragments of 18 S- and 28 S-like genes of the ribosomal RNA (rRNA) of Tetrahymena pyriformis were tested in this study. The genetic similarity tree constructed for the species studied agrees with evidence from classical taxonomy based on morphological, ecological, anatomical, and physiological characters.

Abstract
Conservatism of primary and secondary structure of osteopontin mRNA in vertebrates of various taxes was studied using computer analysis and blot-hybridization procedure. Relatively high rate of evolution of a nucleotide sequence of osteopontin gene was revealed. Formation of hairpin-loop structures by adjacent sequences and a high content of AU-pairs indicate more flexible structure of the mammalian osteopontin mRNA as compared with the avian one. It has been detected some AU-enriched regions in 3'-terminal untranslated sequences, which presence is characteristic for short-lived mRNA. Evolutionary conserved subsequences in 3'- and 5'-terminal regions were suggested to be determinants of RNA-protein interaction in cytoplasm.

Abstract
HindIII restriction digests of the rDNA repeat unit of the German cockroach, Blattella germanica, reveal significant intraspecies sequence polymorphism. This variability is probably caused by structural differences within the nontranscribed spacer regions (NTS) of the ribosomal repeat unit. HindIII rDNA fragment polymorphisms in three cockroach strains show that individuals from different populations may have different HindIII rDNA patterns, whereas individuals within populations exhibit relatively similar rDNA patterns. We suggest that HindIII restriction fragment polymorphisms within cockroach ribosomal DNA will be a valuable tool for measuring population-level parameters within and between natural cockroach populations.
