First Data on the Contact Zone and Hybridization between the Cryptic Species of Shrews Sorex araneus and S. satunini (Eulipotyphla, Mammalia). DOKLADY BIOLOGICAL SCIENCES : PROCEEDINGS OF THE ACADEMY OF SCIENCES OF THE USSR, BIOLOGICAL SCIENCES SECTIONS 2020; 494:251-254.

Abstract
For the first time, based on sequence variation of microsatellite loci and the mtDNA cytb gene fragment, population genetic structure of the common shrew and Caucasian shrew in their contact zone was investigated. It was demonstrated that, although there was no complete reproductive isolation between the species under consideration, the gene flow was considerably limited. These data testify to the established reliable reproductive barriers between the common shrew and Caucasian shrew.

Abstract
SummaryThe shape of platelets in circulating blood and alterations of this shape after the contact of platelets with glass surfaces, as well as spontaneous platelet aggregation, were examined in patients with acute myocardial infarction (AMI) and in controls.The shape of circulating platelets were studied by scanning electron microscopy and the spreading - by differential interference contrast microscopy.Most platelets circulating in the blood of the patients with AMI had non-activated discoid shape; the percentage of these nonactivated platelets was similar to that in the control group. However, these platelets of many AMI patients acquired an increased ability to undergo morphological changes after contact with glass. The percentage of spread platelets in controls was never higher than 50%. In contrast, this percent was higher than 50% in 73% of patients with AMI. Increased spontaneous platelet aggregation was determined only in 30% of AMI patients.

Abstract
In this work the genetic variability of the common shrew populations Sorex araneus L. in Eastern Europe was studied via sequencing of the mitochondrial gene cyt b. A total of 82 sequences of the mitochondrial gene cyt b with a length of 953 basepairs were analyzed, including five chromosome races in a continuous area of the species in forest zone and two races in fragmented area in the steppe zone. Phylogeographic subdivision of the common shrew was not expressed, and there was no significant correlation between genetic and geographic distances in continuous areas. We did not acquire convincing evidence of the influence of narrow hybrid zones between chromosome races on the flow of neutral alleles. A significant p-distance (0.69 ± 0.27%) of geographically close populations of the chromosome race Neroosa indicates the formation of the karyotype of this race in the Pliocene or Pleistocene. In our work, the phylogeographic structure was determined more by species area fragmentation than by its karyotypic features.

Abstract
This paper has at its objective the assembling of liposomal assemblies onto nanoparticles. In this manner, one generates nanoparticles with a high loading capacity. Thus, spherical spherical polycationic "brushes" (SPBs) were synthesized by graft polymerizing a cationic monomer, (trimethylammonium)ethylmethacrylate chloride, onto the surface of monodisperse polystyrene particles, ca. 100 nm in diameter. These particles were complexed with small unilamellar anionic liposomes, 40-60 nm in diameter, composed of egg lecithin (EL) and anionic phosphatidylserine (PS(1-)) in PS(1-)/EL ratios from 0.10 to 0.54, a key parameter designated as ν. These complexes were then characterized according to electrophoretic mobility, dynamic light scattering, conductivity, fluorescence, and cryogenic transmission electron microscopy, with the following main conclusions: (a) All added liposomes are totally associated with SPBs up to a certain saturation concentration (specific for each ν value). (b) The number of liposomes per SPB particle varies from 40 (ν = 0.1) to 14 (ν = 0.5). (c) At sufficiently high liposome concentrations, the SPBs experience an overall change from positive to negative charge. (d) SPB complexes tend to aggregate when their initial positive charge has been precisely neutralized by the anionic liposomes. Aggregation is impeded by either positive charge at lower lipid concentrations, or negative charge at higher lipid concentrations. (e) The liposomes remain intact (i.e., do not leak) when associated with SPBs, at ν ≤ 0.5. (f) Complete SPB/liposome dissociation occurs at external [NaCl] = 0.3 M for ν = 0.1 and at 0.6 M for ν = 0.5. Liposomes with ν = 0.54 do not dissociate from the SPBs even in NaCl solutions up to 1.0 M. (g) Complexation of the PS(1-)/EL liposomes to the SPBs induces flip-flop of PS(1-) from the inner leaflet to the outer leaflet. (h) The differences in the ability of PS(1-) (a cylindrical lipid) and CL(2-) (a conical lipid) to create membranes defects are attributed to geometric factors.

Abstract
The contact points of four karyotypic races (St. Petersburg, Moscow, Seliger and West Dvina) of the common shrew Sorex araneus L. were studied at the Valdai Hills (European Russia) in an area unimpeded by geographic barriers. The populations of the races are separated by narrow hybrid zones that represent the most complex heterozygous hybrid karyotypes. At these points of contact, the morphometric differentiation of karyotype races was examined in 12 cranial measurements in 190 shrews of a known karyotype. A. comparison of the mean values in studied samples of immature shrews revealed statistically significant differences and the correlation of some measurements in order to describe the level of musculus temporalis. It has been proposed that morphometric differences in the karyotypic races were preserved and accumulated because of a 50% reduction of the frequencies of hybrids. The deviation from the Hardy-Weinberg ration in the frequencies of the genotype and haploid sets of chromosomes in the hybrid zones can be attributed to a number of fatalities of hybrid embryos or the nonrandom mating of karyotypic races. The ethological isolation might arise in the evolution of some karyotypic races from the reduced fitness of the hybrids.

Abstract
The contact zone between Moscow and Western Dvina chromosomal races of common shrew Sorex araneus L. at the south of the Valdai Hights was traced over a distance of 20 km. Within this, close to parapatric, contact zone of chromosomal races the width of sympatry zone was about 500 m (the narrowest among currently known hybrid zones), and the proportion of hybrids was 24.3%. It was shown that in bimodal hybrid zones between chromosomal races of common shrew the width of sympatry zones varied from 0.5 to 13 km. This width does not correlate with the cytogenetic features of the hybrids, and seems to be determined by competitive relations between the races. The hybrid proportion is determined by the type of hybrid heterozygosity, and decreased in the race sympatry zone from 33-40 to 21.5-25.2%. The decrease of the hybrid proportion can be associated with the abnormal fertility of either the first generation, or the backcross hybrids.

Abstract
The variation of microsatellite loci in 130 individuals of four common shrew chromosome races (Moscow, Western Dvina, Seliger, and St. Petersburg) contacting on the Valdai Hills was studied. A low level of genetic differences between the chromosome races, which differ at three-five fixed diagnostic metacentric chromosomes, was found. The genetic differentiation within the races is more considerable as compared with that between the races. A high deficiency in heterozygotes was recorded; presumably, this is connected with regular variation in the population sizes. It is assumed that the fixation of centric chromosome fusions was supported by selection (drive) in the evolution of the common shrew against the background of a neutral evolution of the microsatellite loci.

Abstract
Using the data of karyological analysis, the phylogenetic relationships of Caucasian shrew Sorex satunini and the cryptic species of superspecies Sorer araneus were examined. In the population of Sorex satunini from the plain of North Ciscaucasia two deeply radiated cytochrome b genes (A and B) were identified. Genetic distance between haplotype A and B groups constituted 0.0675 +/- 0.008, which is higher than any distance in superspecies S. araneus. Possible introgression of type B haplotypes from the populations of the evolutionary lineage S. subaraneus--S. araneus in Pleistocene and the time of the appearance of the chromosomal polymorphism of S. araneus is discussed. Our results show that the use of only one mitochondrial marker can lead to false conclusions on taxonomic diversity

Abstract
The work attempts to explain the previously discovered phenomenon of excessive taxonomic status of the species and subspecies of Cuban hutias relative to their protein genetic divergence. The reasons underlying the fragmentary distribution of the species belonging to the family Capromyidae over the Antilles and Bahamas is also considered. Samples of four geographically distant hutia (genera Capromys and Mysateles) populations inhabiting different biotypes were assessed according to 32 allozyme loci. It has been demonstrated that the interpopulation and subspecies differentiation in the gene frequencies in these genera is very low. As for the pattern of polymorphism (Shannon?s measure), the populations and subspecies within these genera are well differentiated and adequate to their morphological differentiation. This suggests that the genetic divergence pattern of hutias in post-Pleistocene was predominantly determined by selection on the background of a relatively rapid formation of multiple morphotypes. It is assumed that the evolution within the family Capromyidae in the earlier and the later periods was associated with the geomorphological and climatic events in the history of the Earth. This standpoint provides for explaining the phenomena of both the excessive taxonomic status of the Cuban Capromyinae and the fragmentary distribution of these species over the Antilles and Bahamas, amazing at a first glance.
