Gene IL6 G(-174)C and gene IL10 G(-1082)A polymorphisms are associated with unfavourable outcomes in patients with acute coronary syndrome

We investigated the association of gene IL6 G(-174)C polymorphism and gene IL10 G(-1082)A polymorphism with coronary artery disease (CAD) in the Russian population. A total of 1145 patients with CAD diagnose on the basis of clinical studies in cardiological hospitals of Moscow, St -Petersburg, Kazan, Chelyabinsk, Perm, Stavropol and Rostov-on-Don. Supervision term was 9.10 +/- 5.03 months (the maximum term 18 months). In case of gene IL10 G(-1082)A polymorphism we determined that patients with CAD diagnose and A alleles gene IL10 had unfavorable outcome more often than patients with homozygous G alleles. Survival time from end point from carrier genotype GA and AA is 11.68 +/- 0.67 months against 12.69 +/- 0.65 months from carrier phenotype GG gene IL10 (chi2 = 4.13, p = 0.042). The group studied do not differ significantly with respect to the distributions of gene IL6 G(-174)C alleles and genotypes. However in case combined group studies of gene IL10 G(-1082)A polymorphism and IL6 G(-174)C polymorphism we determined that patients with CAD diagnose and carrier genotype GG gene IL6 and genotype GA and AA gene IL10 had unfavorable outcome more often (survival time 11.01 +/- 1.24 months) than patients with genotype CC and CG gene IL6 and genotype GG gene IL10 (survival time 13.28 +/- 0.83 months) chi2 = 10.23, p = 0.017. The obtained data allows assuming the important role of the IL6 and IL10 genes which are responsible for functioning of inflammation system, in the accelerated formation of failures at the patients who had a coronary syndrome.     

The polymorphisms G(−174)C in IL6 gene and G(−1082)A in IL10 gene are associated with poor outcomes in patients with acute coronary syndrome

Association between the rates of poor outcomes in the patient cohort with acute coronary syndrome and polymorphisms G(?174)C in the IL6 gene and G(?1082)A in the IL10 gene were determined. In total, 1145 patients hospitalized for coronary artery disease to cardiological hospitals of Moscow, St. Petersburg, Kazan, Chelyabinsk, Perm, Stavropol, and Rostov-on-Don were examined. The mean observation period was 9.10 ± 5.03 months (maximal, 18 months). Analysis of the survival of the patients with acute coronary syndrome that carried allele A has demonstrated that the presence of IL10 gene polymorphism G(?1082)A is associated with more frequent poor outcomes as compared with GG genotype. The survival time to endpoint for the carriers of GA and AA genotypes was 11.68 ± 0.67 months versus 12.69 ± 0.65 months for the carriers of GG genotype in IL10 gene (χ² = 4.13, p = 0.042). As for the IL6 gene polymorphism G(?174)C, survival rate analysis did not detect any significant association with the risk for poor outcome. However, joint analysis of these polymorphisms in both genes has demonstrated that characteristic of the patients with acute coronary syndrome that carry GG genotype of IL6 gene and GA and AA genotypes of IL10 is a higher rate of poor outcomes (time to endpoint, 11.01 ± 1.24 months) as compared with the carriers of IL6 gene CC and CG genotypes and IL10 gene GG genotype (time to endpoint, 13.28 ± 0.83 months (ξ² = 10.23, p = 0.017). These data suggest that the genes IL6 and IL10, whose products are involved in the control of inflammatory response, play an important role by increasing the probability of poor outcomes in the patients with acute coronary syndrome.     

Current state of epidemiologic surveillance of natural foci of plague of North Caucasus

Information on the epizootic situation in plague in the natural foci of North Caucasus and on the influence of a number of anthropogenic and natural factors on this situation is presented. The data given in this work indicate that under the conditions of the anthropogenic transformation of landscapes the character of the epizootic manifestations of plague is changed and new factors, capable of aggravating epidemiological situation, appear. In addition, some other factors must be considered, such as the insufficient financing of reliable field surveys at present, the impossibility of making reliable epizootological studies due to causes of the social character (armed conflicts), thus making it impossible to evaluate, with a sufficient degree of reliability, the real epizootic state of a number of territories and, therefore, the risk of human infection. In this connection the necessity to carefully plan prophylactic measures and measures aimed at the localization and liquidation of the probable foci of infection arises.     

Changes in fatty acids contents and growth characteristics in transformed oilseed rape (Brassica napus)

Spring oilseed rapeBrassica napus L. ssp.oleifera cv. HM-81 was transformed with T_L-DNA of the Ri plasmid of the agropine strainAgrobacterium rhizogenes 15834. Selfed progenies (R₂ and R₃ generations) were studied for changes in values of growth characteristics and fatty acids contents. Transformants are ‘homozygous’ for T_L-DNA. Both generations of transformants differed significantly from the nontransformed control plants in reduced length, lower number of pods per plant, lower total mass of seeds and the higher number of branches. The contents of palmitic, linoleic and linolenic acids were significantly higher in transformants when compared with the control. On the contrary, the contents of both stearic and oleic acids were in most of transformants significantly lower. Only traces of erucic acid (less than 0.05 % ) were found, both in transformed and nontransformed plants.     

Diversity and ecology of algae from the Nahal Qishon river,northern Israel

In 59 samples of periphyton and phytoplankton collected in 2002 - 2003 from the Nahal Qishon (Qishon River), northern Israel, we found 178 species from seven divisions of algae and cyanoprocaryotes. Diatoms, clorophytes, and cyanoprocaryotes prevail. Nitzschia and Navicula (Bacillariophyta) are the most abundant. Most of the species are cosmopolitan or widespread, except Lagynion janei (Chrysophyta), which is endemic for the Mediterranean Realm. About 17% of species (26) are new for Israel and five of them represent the first recorded genera: Crinalium endophyticum Crow, Actinocyclus normanii (Gregory) Hustedt, Rhizoclonium hieroglyphicum (Agardh) Kütz (Chlorophyta), Lagynion janei Bourelly, and Stylococcus aureus Chodat. Most of them come from a rare riverine assemblage with red alga Audouinella pygmea, as well as from the estuarine assemblage. Alkaliphiles predominate among the indicators of acidity, with few acidophiles confined to the communities under the impact of industrial wastes. Among the indicators of salinity, most numerous are the oligohalobien-indifferents and species adapted to a moderate salinity level. The relative species richness of ecological groups and the indices of saprobity are correlated with changes in conductivity, pH, and N-nitrate concentration. Indicators of organic pollution fall in the range of betameso- to alfamesosaprobic self-purification grades. Our studies show ecological significance of the Nahal Qishon as a model for a strongly disturbed aquatic ecosystem in the coastal zone of eastern Mediterranean.
