Аннотация: The role of key environmental factors in adaptation of spore-forming and non-spore-forming transgenic microorganisms (TM) have been studied in model ecosystems. Model TM Escherichia coli Z905 (bearing plasmid genes of bacterial luminescence Ap(r)Lux(+)) has been found to have a higher adaptation potential than TM Bacillus subtilis 2335/105 (bearing genes of human alpha 2-interferon Km(r)lnf(+)), planned for employment as a living vaccine under varying environmental conditions. Effects of abiotic factors on migration of natural and recombinant plasmids between microorganisms under model ecosystem conditions has been estimated. The transgenic microorganisms with low copy number survived better under introduction conditions in the microcosms studied. This trend has been shown to be independent of the microcosm type and its complexity. (C) 2001 COSPAR. Published by Elsevier Science Ltd. All rights reserved.

Prey-predator model with purposeful migration of individuals [Текст] / M. G. Sadovsky // Zhurnal Obshchei Biol. - 2001. - Vol. 62, Is. 3. - P. 239-245. - Cited References: 22 . - ISSN 0044-4596

РУБ Biology

Аннотация: Two species "prey-predator model" where the individuals purposefully migrate between two habitats is considered. A migration is regarded as transference from one habitat to another yielding in maximization of average (over two habitats) coefficient of reproduction. Targeted migration results in the increase in average abundance of population comparing with discrete analogies of classic equations of Volterra and also to the enlargement of the area of the admissible meanings of parameters. A great variety of dynamic regimes has been observed, some of them could be interpreted as outbreak explosion.

Аннотация: Two-section enclosures were designed for the investigation of the effect of various physicochemical and biological factors on vertical distribution of zooplankton in situ. The framework of the enclosure was a cylindrical polyethylene column without any partitions inside, in which the isolation of animals in different sections after in situ exposure was achieved by pinching the flexible central part of the column. Enclosures were tested at the brackish stratified meromictic Lake Shira (Russia, Khakasia). The absence of fish and carnivorous zooplankton in the lake suggests that the vertical distribution of zooplankton is mainly determined by physicochemical gradients in the water column. Experiments and field observations demonstrated that all age and size groups of Arctodiaptomus salinus and Brachionus plicatilis strongly avoided surface layers during the daylight. The escape of zooplankton from the anoxic hypolimnion was less active. Statistically significant avoidance was observed only for copepodites C4-C5 and females of A. salinus. The relatively simple construction of the columns and easy handling during the experiment were the factors that favoured the use of this device to perform in situ basic tests of the effect of different factors on the vertical distribution of zooplankton.

Аннотация: Three levels of chemical communications involved plankton Crustacea are considered: 1) Influence of zooplankton excretion on phytoplankton; 2) Influence of zooplankton excretion on the individuals of the same or other species of the same trophic level; 3) Influence of chemical cues released by predatory zooplankton and fish on herbivorous zooplankton. The data on the influence of excreted cues on some physiological (growth, reproduction, feeding, etc.) and behavioural (vertical and horizontal migrations) characters of planktonic crustaceans are presented. Ecological role and chemistry cues responsible for the interactions of different trophic levels can be different. It is considered that chemical communications in aquatic ecosystems can be provided with: 1) Species-specific cues that strictly influence particular biological functions (communication system of feromone type); 2) Non-specific cues that strictly influence particular functions (system of regulator, that act at the whole ecosystem as the hormonal system of an organism). 3) Non-specific substances with broad (nonspecific) influence-toxic substances of "biocondition substances" according to classification of Novikov and Kharlamova (2000).

Effect of daily variations in abiotic conditions on the distribution and production of phytoplankton in Lake Baikal / A. V. Kartushinskii // Water Resources. - 1997. - Vol. 24, Is. 1. - P60-67 . - ISSN 0097-8078
Аннотация: Based on experimental and field data, the character of daily variations in the production and distribution of the phytoplankton biomass under various hydrodynamic and thermodynamic conditions is analyzed. The effects of density stratification, wind and light conditions, vertical water flows, and daily migration of the Zooplankton on the life activity of the phytoplankton are simulated. It is shown that the vertical distribution of the maximum concentrations of the phytoplankton depends on daily variations in a number of abiotic factors.

Model of population with optimally migrating individuals [Текст] / S. A. Motolygin, M. G. Sadovsky, D. A. Chukov // Zhurnal Obshchei Biol. - 1999. - Vol. 60, Is. 4. - P. 450-459. - Cited References: 21 . - ISSN 0044-4596

Аннотация: The new model was proposed to study the dynamic of spatially distributed populations with nonrandom migrating individuals. All migrations are resulted in maximization of the average net reproduction rate taking into account the cost of migration. The model belongs to a box type: individuals migrate between two stations and have complete information about living conditions both in the stations of residence and migration. The information is determined by dependence of reproduction rate on the abundance of individuals in the station. Numerical experiments showed that taking into account the goal-directed migrations caused the following effects: significant extension of the value of external conditions leading to the stable existence of population; increase in the average abundance of population; broadening of the observed set of dynamic regimes. The limitation of the model application are discussed.

Аннотация: Using mathematical modeling methods, the work investigates possible existence of a phytoflagellate population in the ecosystem of a stratified lake (Lake Shira, Khakasia, Russia). Until this study was carried out, no phytoflagellate population had been detected in the lake, although there had been indirect evidence of the possible presence of a cryptomonad population in this water body. To answer the question if this population may be present in this water body, as the first step of investigation, a mathematical model was developed describing the microorganism biomass dynamics and phytoflagellate relationship with the lake food web. The calculations showed that cryptophytic algae were abundant in the water column layers above the lake chemocline at the beginning of summer but showed low biomass concentrations during other periods of time. In the summer following the construction of the model, samples were collected from Lake Shira, as the next step of the study. A cryptophytic algae population was found in the water column, and the pattern of its distribution in the ecosystem was similar to that predicted by the model. In addition to that, we studied theoretically possible reasons for the early summer development of the population in the deep water layers and found that it was the result of the mixotrophic feeding strategy of cryptomonads and trophic interactions in the food web. The study shows that preliminary modeling of the locational and temporal distribution of populations whose presence in the ecosystem is only suggested by indirect evidence may be useful as a tool for searching for the species in natural ecosystems and as an approach enabling a more accurate description of the food web structure of a water body.

Аннотация: MicroRNAs epigenetically regulate physiological and pathological processes. Previously, we found that miR-204-5p is expressed at low levels in melanoma cells, and an increase in its level leads to a change in proliferation, migration, and invasion of these cancer cells. Now, using bioinformatics analysis, it has been shown that the target of miR-204-5p is FOXC1 transcription factor, which is implicated in carcinogenesis. Using the luciferase reporter assay, it was found that miR-204-5p suppresses expression of the FOXC1 gene by binding to its 3' non-coding region. Transfection of small interfering RNA (siRNA) targeting FOXC1 into melanoma cells caused a decrease in miR-204-5p levels, which is consistent with the generally accepted concept of feedback regulation of miRNA expression by target genes. According to the results of the MTT test and fluorescence microscopy, the proliferation level of melanoma cells under the influence of siRNA to FOXC1 decreased 72 h after transfection. Changes in the ratio of cells by cell cycle phase were analyzed using flow cytometry. Regulatory relationships between FOXC1 and miR-204-5p, and an inhibitory effect of FOXC1 knockdown on melanoma cell proliferation were revealed. Based on the results, it can be assumed that miR-204-5p regulates proliferation of melanoma cells by affecting FOXC1 expression.

Аннотация: The seasonal formation of annual rings on the scales of Baikal grayling from the middle reaches of the Yenisei River has been studied to find out the reasons for the high growth rate of the grayling under altered temperature regime downstream of the dam of the Krasnoyarsk Hydroelectric Plant. The number of circuli outside the last identified annuli and in the second, third, and fourth completed annuli was estimated on 569 fish caught during the annual cycle. The von Bertalanffy growth function was used to describe the increment in the number of circuli over a year. The calculation showed that a new annual ring was produced in July. In November, there was no statistically significant difference between the circulus number in scale increment and the circulus number in the corresponding completed annuli of older fish. Thus, despite the increased duration of the period with optimal water temperatures downstream of the dam of the Krasnoyarsk Hydroelectric Plant, fish growth was observed in a limited period of the year, from July to November. The probable reason for the high growth rate of grayling in the study area is that the fish do not have to waste energy on seasonal migration to the tributaries. Taking into account that grayling biomass production in the middle Yenisei occurs from July to November, we can recommend shifting the dates of commercial fishing for grayling to the end of this period-November-December.

Аннотация: Populations of brown trout in the Mzymta River and its tributaries include anadromous (mainly female) and resident (mainly males) fish. Some resident males in the basin of the Mzymty River attain sexual maturity at the age 1+, and resident females mature at the age 2+ or 3+. The maximum age of resident fish is 4+ in the samples studied. Migrations of anadromous brown trout to the sea occur at the ages 1+, 2+, or 3+. Future spawners spend from 1 to 4 years at feeding grounds in the sea. Smolts of the population are characterized by performing not only spring but also autumn migrations to the sea. One smolt specimen has been detected upstream from the dam in the river where spawners of anadromous brown trout do not migrate; this means that the capability for sea migrations persists long in the population represented only by resident specimens of brown trout. The diversity of life cycles and ecological forms in populations of brown trout is not lower than in populations of brown trout in Northern and Western Europe. The comparison of the data obtained with published data makes it possible to come to the conclusion about the high plasticity of ontogenesis of Black Sea brown trout.

Аннотация: The present study reports construction of wound dressing materials from degradable natural polymers such as hydroxy derivatives of carboxylic acids (PHAs) and 3-hydroxybutyrate/4-hydroxybutyrate [P(3HB/4HB)] as copolymer. The developed polymer films and electrospun membranes were evaluated for its wound healing properties with Grafts—elastic nonwoven membranes carrying fibroblast cells derived from adipose tissue multipotent mesenchymal stem cells. The efficacy of nonwoven membranes of P(3HB/4HB) carrying the culture of allogenic fibroblasts was assessed against model skin defects in Wistar rats. The morphological, histological and molecular studies revealed the presence of fibroblasts on dressing materials which facilitated wound healing, vascularization and regeneration. Further it was also observed that cells secreted extracellular matrix proteins which formed a layer on the surface of membranes and promoted the migration of epidermal cells from the neighboring tissues surrounding the wound. The wounds under the P(3HB/4HB) membrane carrying cells healed 1.4 times faster than the wounds under the cell-free membrane and 3.5 times faster than the wounds healing under the eschar (control).The complete wound healing process was achieved at Day 14. Thus the study highlights the importance of nonwoven membranes developed from degradable P(3HB/4HB) polymers in reducing inflammation, enhancing angiogenic properties of skin and facilitating better wound healing process. © 2016, Springer Science+Business Media New York.

Аннотация: The number of circuli between annual scale rings of grayling Thymallus baicalensis Dybowski, 1874 sampled in the Yenisei River in the downstream section of the Krasnoyarsk Hydroelectric Power Station, which does not freeze in winter, have been investigated and compared with populations of grayling from large tributaries of the Yenisei River (Amyl, Kan, Nizhnyaya Tunguska, and Bolshaya Kheta). It has been shown that graylings inhabiting the Yenisei River have a significantly higher (1.5-2.0 times, p < 0.01) number of circuli in the second, third, and fourth annual rings of the scales than in the populations from the tributaries, which corresponds to a higher growth rate of the grayling population in the Yenisei River. An assumption is made about the transition of graylings inhabiting the Yenisei River channel in the lower reaches of the hydroelectric station to a sedentary lifestyle.

Effect of humic acid on absorption-release processes in the bottom sediments-Yenisei river water system as studied by dual-column ion chromatography and gamma-ray spectrometry [Text] / L. G. Bondareva, O. P. Kalyakina, A. Y. Bolsunovskii // J. Anal. Chem. - 2006. - Vol. 61, Is. 4. - P354-358, DOI 10.1134/S1061934806040101. - Cited References: 11 . - 5. - ISSN 1061-9348

Аннотация: The effect of humic acid on absorption-release processes in the bottom sediments-Yenisei river water system was studied by dual-column ion chromatography and gamma-ray spectrometry. With the use of ion chromatography, it was found that processes related to the absorption of SO42- and Cl- anions by a solid phase with the release of NO3-, PO43-, and F- to a liquid phase competed in the test systems as the concentration of water-soluble organic carbon (WSOC) was increased. Only the test anions were released in the systems without the introduction of an additional amount of WSOC as humic acid. With the use of gamma-ray spectrometry, it was found that the release of Co-60, Eu-152, and Am-241 radionuclides to the liquid phase in the systems with added humic acid began much earlier than in the system without the addition of humic acid. In this case, the amount of released radionuclides was greater than the amount of radioisotopes released in the system without the addition of humic acid: similar to 25% Am-241, similar to 3% Eu-152, and similar to 0.8% Co-60 in the system with added humic acid or 0.8% Eu-152 and 0.1% Co-60 in the system without the addition of humic acid. The Am-241 radionuclide was not determined in the system without the addition of humic acid. An increase in the concentration of WSOC in the experimental system of bottom sediments-Yenisei river water initiated the release of Co-60, Eu-152, and Am-241 anthropogenic radionuclides from bottom sediments because of the formation of soluble complexes capable of migration. An increase in the concentration of WSOC had almost no effect on the release of K-40 and Cs-137 radionuclides.

Аннотация: Methods of atomic absorption, flame photometry, and emission spectral analysis were used to study the concentrations of metals in water and major ecosystem components of the Yenisei River upstream of Krasnoyarsk City (conventionally background area). The mean bulk concentrations of Al and Cu in water exceeded the MAC for water bodies used for fishery. Cu concentration in freshwater shrimp was found to be reliably higher than that in the link of primary producers (periphyton), and Cd concentration in caddis fly larvae was found to exceed that in water moss. The maximal concentrations of metals among the examined aquatic organisms were recorded in periphyton. Cr concentration in the muscles of Arctic grayling was found to exceed some international standards. В© 2009 Pleiades Publishing, Ltd.

Аннотация: Asynchronous vertical migrations of calanoid copepods Arctodiaptomus salinus were studied in two stratified lakes in the south of Siberia using the method of two-section enclosures. It was found that the presence of a pronounced thermocline and a depth maximum of phytoplankton (Lake Shira) contributes to the appearance of intensive individual migrations of copepods between areas of the epi- and hypolimnion.
