Parallelism in eco-morphology and gene expression despite variable evolutionary and genomic backgrounds in a Holarctic fish.

Understanding the extent to which ecological divergence is repeatable is essential for predicting responses of biodiversity to environmental change. Here we test the predictability of evolution, from genotype to phenotype, by studying parallel evolution in a salmonid fish, Arctic charr (Salvelinus alpinus), across eleven replicate sympatric ecotype pairs (benthivorous-planktivorous and planktivorous-piscivorous) and two evolutionary lineages. We found considerable variability in eco-morphological divergence, with several traits related to foraging (eye diameter, pectoral fin length) being highly parallel even across lineages.

Features of cellular structure of the induced sputum and profile of cytokines at sintropiya of bronchial asthma and obesity at young patients.

Aim: To estimate changes of cellular structure of the induced sputum at young patients with bronchial asthma at interrelations with BMI and level of cytokines in blood plasma.

The article presents the results of questionnaire survey of mothers brining up disabled children aged from 1 to 4 years organized to evaluate respondents' satisfaction with delivered medical care and to establish mothers'awareness of disease of child. The results testify that alongside with applied measures directed to improve quality of medical care the activities are needed to be applied to parents to increase their awareness of child health condition, causes of development of disease and characteristics of its course, methods and perspectives of treatment and prognosis of disease.

Phylogeography and sympatric differentiation of the Arctic charr Salvelinus alpinus (L.) complex in Siberia as revealed by mtDNA sequence analysis.

Sequence variation in the mtDNA control region of Arctic charr Salvelinus alpinus and Dolly Varden Salvelinus malma from 56 Siberian and North American populations was analysed to assess their phylogeographic relationships and the origins of sympatric forms. Phylogenetic trees confirm the integrity of phylogroups reported in previous mtDNA studies except that the Siberian group does not separate as a single cluster. Haplotype network analysis indicates the proximity of Siberian and Atlantic haplotypes.

[Microsatellite DNA variability in the populations of muskoxen Ovibos moschatus acclimated to the Russian North].

The muskoxen populations introduced to the Taimyr Peninsula and Wrangel Island in 1974 to 1975 were examined for sequence variation at seven microsatellite loci. Donor material originated from the populations of Banks Island (Canada) and Eastern Greenland. Relative to the allele frequencies, both introduced populations demonstrated rather strong deviation from the populations of the native range.

[Clinical picture and treatment of bronchial asthma comorbid with cardiovascular diseases].

Aim: To evaluate prevalence of cardiovascular diseases (CVD) in bronchial asthma (BA) patients and effects of CVD on BA course.

Material And Methods: Register data for 2005 have been analysed for 5104 BA outpatients living in Krasnoyarsk city (pulmonary ventilation, ECG, echocardiography, duration of BA, number of exacerbations for the last 12 months, number of hospitalizations, disability, BA complications, BA and CVD treatment).

Results: Combination of BA with CVD was observed in 88.

[Variation in mitochondrial DNA in Far Eastern mullet pilengas, Liza haematocheilus Temminck and Schlegel, acclimatized in the Azov-Black Sea basin].

This study continues the investigation of genetic variation in the populations of native and acclimatized in the Azov-Black Sea basin pilengas from the Sea of Japan. The previous comparison based on allozyme analysis was supplemented by analysis of restriction polymorphism of a mitochondrial DNA fragment containing the cytochrome b gene and the D-loop. Five out of fifteen endonucleases tested detected polymorphic sites.

[Genetic differentiation of pink salmon oncorhynchus gorbuscha Walbaum in the Asian part of the range].

Genetic variation at 19 allozyme (including 11 polymorphic) and 10 microsatellite loci was examined in the population samples of odd- and even-broodline pink salmon from the southern part of Sakhalin Island, Southern Kuril Islands, and the northern coast of the Sea of Okhotsk. The estimates of relative interpopulation component of genetic variation over the allozyme loci, per broodline, were on average 0.43% (GST), while over the microsatellite loci it was 0.

[Genetic divergence in pink salmon introduced into the European north of Russia: microsatellite and allozyme variation analysis].

The 1985 introduction into the European North of Russia resulted in the formation of a large stock of pink salmon of the odd-year breeding line. To assess the divergence of the new population and the role of various microevolutionary factors, variation of four microsatellite loci and fifteen genes encoding proteins (allozymes) in samples of fish, running for spawning in rivers of the new area, and in samples from the donor population of the Ola River (Magadan oblast). In the generations 8 and 9 of the introduced pink salmon of the odd-year line, the genetic diversity (the number of alleles and the mean heterozygosity) both at allozyme and at microsatellite loci was significantly lower, than that in the donor population.

[Genetic divergence of chars of the genus Salvelinus from Kronotsky Lake (Kamchatka Peninsula)].

Chars from the genus Salvelinus, inhabiting lakes and lake-river systems, belong to morphologically and ecologically different forms whose taxonomic status is under dispute. In the present work, we have examined genetic variation and divergence in various chars from the Kronotsky lake basin: the lacustrine chars (white, nose, and long-head) and Dolly Varden char Salvelinus malma. The study was conducted using analysis of allozyme and microsatellite loci, myogens, RAPD, and restriction analysis of two mtDNA segments.

[Acclimatization of salmon Oncorhynchus gorbuscha (Walbaum) in the European north: data from restriction analysis of mtDNA].

Pink salmon spawners introduced into the White Sea basin (the Umba River) were compared to the spawners from the basin of the Sea of Okhotsk (the Ola River) using restriction analysis of two fragments of mitochondrial DNA (mtDNA). One of the fragments included genes ND5/ND6, the other, the cytochrome b gene and the control region. It was found that mtDNA variation and diversity at the earlier examined nuclear allozyme genes significantly decreased in the odd broodline of pink salmon 8 years after the introduction.

[Genetic changes in pink salmon Oncorhynchus gorbuscha Walbaum during acclimatization in the White sea basin].

Genetic parameters of pink salmon introduced into the White Sea basin in 1985 and 1998 were compared to the corresponding parameters of the donor population from the Ola River (Magadan oblast). The detected genetic differences indicate that colonization of a new area is accompanied by impoverishment of the gene pool of the native population. This effect was particularly marked in the odd-year line of pink salmon introduced in 1985.

[Animal lipoxygenases. The nature of substrates and changes in conformation of reticulocyte lipoxygenase in its interaction with membranes].

In the presence of natural (liver mitochondria and microsomes) and artificial (liposomes from saturated phosphatidyl cholines) membranes, the rate of oxidation of an emulgated polyunsaturated fatty acid by reticulocyte lipoxygenase sharply increases and correlates with the amount of polyunsaturated fatty acid incorporated into the membrane. Hydrolysis of egg lecithine polyunsaturated acyls by phospholipase A2 drastically increases the rate of their enzymatic oxidation. It was shown that 15-hydroperoxyarachidonate is incorporated into lecithine liposomes at a much slower rate that the non-oxidized arachidonic acid.

On the nature of the stimulation of the lipoxygenase from rabbit reticulocytes by biological membranes.

The oxygenation of concentrated emulsions (about 260 microM) of arachidonic acid or linoleic acid catalyzed by the purified lipoxygenase from rabbit reticulocytes is strongly stimulated in the presence of low concentrations of beef heart submitochondrial particles or other membrane preparations. Maximal stimulation was observed at a proportion of about 5 mumoles polyenoic acid per mg of membrane protein. Whereas at a constant ratio of arachidonic acid and membranes the reaction rate obeyed the Michaelis-Menten kinetics with an apparent Km value of 75 microM for arachidonic acid, sigmoid kinetics was observed under conditions of constant concentration of membranes and, consequently, varying proportions of arachidonate and membranes.
