    Cultivars of Thuja L. genus in the Botanical Garden of the Adyghe state university

    The paper shows the results of introduction testing of cultivars of Thuja genus in the Botanical garden of Adyghe State University. Emphasis is placed on the water regime of plants as a measure of ecological species plasticity. The seasonal dynamics of the tissue water-holding capacity of different garden forms of arborvitae in the botanical garden of Adyghe State University is shown. Maximum spring water loss and more stable autumn-winter performance of the water regime, with a high water-holding capacity of tissues, are identified. On the basis of physiological studies of cultivars of Thuja genus, as well as proceeding from the biological characteris-tics, their prospects are evaluated.

    Association of IL-4 and IL-2 gene polymorphisms with the malignant growths of female reproductive organs

    Frequencies of single nucleotide polymorphisms (SNP) in the promotor regions of the IL-4 (C589T; rs2243250) and IL-2 (T330G; rs2069762) cytokine genes are typified for malignant growths of female reproduc-tive organs (a mammary gland, a body and a uterus neck) using an allele-specific primers (NPO Litex, Moscow) at inhabitants of the Adyghea Republic. No interethnic distinctions in distribution of alleles and IL-2 and IL-4 genotypes at the Adyghes (n=39) and Russians (n=65) were detected. The oncological patients unlike donors show the authentically (Ρ≤0,05; χ2=10,96) increased frequencies of 589T of alleles and TT of genotypes of the main anti-inflammatory IL-4 cytokine. Depending on histotypes and organ localization of new growths of female reproductive organs, no statistically significant differences in distribution of SNP of IL-2 and IL-4 genes were found. 589T IL-4 allele is associated with a tumoral progression. The availability of 589T (IL-4) and T330 (IL-2) of alleles is interfaced to fast progressing of neoplasia of female reproductive organs.

    Dynamics of a functional condition of an organism of 12-13 year-old juveniles as a criterion for adaptation to the educational environment

    The integrated approach to research of a functional condition of juveniles' organisms during the aca-demic year was used to estimate functional reserves of cardiorespiratory system, the character and the amount of physiological expenditures in school students' adaptation. Sexual differencies in adaptative abilities of I2-I3 year-old students' organisms were revealed. The processes of development and the adaptative changes in 12-13 year-old girls' organisms are shown to be more energy – consumptive than those of boys of their age.

    Toll-like receptor gene polymorphisms, associated with a hereditary history and age of bronchial asthma manifestation

    As a result of study of association of three single nucleotide polymorphisms (SNP) of Toll-like receptor genes of membrane TLR4 (missens-mutations of Asp299Gly; rs4986790 and Thr399Ile; rs4986790) and intra-cellular TLR9 (A2848G; rs352140 – nucleotide replacements in the coding region of a gene) with bronchial asthma depending on age of manifestation and hereditary history, statistically significant differences in frequen-cies of SNP genotypes of an intracellular TLR9 gene are revealed between donors and patients. For A2848/2848G of the polymorphisms located in the coding region of an intracellular TLR9 gene, the association is detected of pathological homozygous (G2848/2848G or GG) genotype with non-hereditary form of bronchial asthma (χ2=3.62; OR=3.03) and mature age of an illness manifestation (χ2=4.69; OR=5.19). At inhabitants of the Adyghea Republic, of three most often registered genotypes of studied SNP TLR4 and TLR9 (AspAsp/ThrThr/AA, AspAsp/ThrThr/AG, AspAsp/ThrThr/GG), the increased risk of development of bronchial asthma at mature age is connected with the combined availability of AspAsp/ThrThr/GG.

    The role of DNA methylation in carcinogenesis

    The origin and development of the tumor is accompanied by serious violations in the nature of DNA me-thylation. Frequently, the total DNA hypomethylation in malignant cells is combined with local hypermethyla-tion, which causes the genomic instability. Of great importance in tumor progression are also violations in the normal regulation of methyltransferases DNMT1, DNMT3a and DNMT3b. Changes in DNA methylation are the potentially sensitive molecular markers to determine the risk of tumor development, to carry out early diagnosis and to develop measures to prevent the development of malignant processes.

    AGT and AGT2R1 gene polymorphisms associated with coronary atherosclerosis in ethnic groups of the Adyghea Republic

    Distribution of M235/235T polymorphisms of AGT gene and A1166C gene polymorphisms of AGT2R1 is investigated by SNP-method (single nucleotide polymorphism) in ethnic groups (Russian and Adygheans) of the Adyghea Republic: donors and patients with different types of cardiovascular disease. The most common 1166C «mutant» allele of vascular angiotensin receptor of type I-2 (AGT2RI) is associated with the risk of coronary atherosclerosis in Adygheans ethnic group (P<0,05; OR=2,77). M235T angiotensinogen gene polymorphisms (AGT) for the Adyghea Republic residents are not prognostically significant.

With the risk of peripheral atherosclerosis (P<0,05; χ2=7,158) is associated to a «normal» G197 allele IL-17A. When cardiovascular disease Ala222Val SNP MTHFR gene residents of the Republic of Adygea does not have prognostic value.

    On the influence of initial modulation of a nonrelativistic electron beam on nonlinear dynamics of tree-wave processes, developing in the regime of the collective Cherenkov effect

    The original analytical methods were used to analyze the influence of initial modulation of the electron beam on the dynamics of tree-wave processes in the regime of the collective Cherenkov effect. It is inferred that the initial value of the beam modulation does not affect amplitude of wave saturation, whereas the time of the volatility stabilizing is strongly reduced with increasing depth of modulation.
