Заглавие : A biological method of including mineralized human liquid and solid wastes into the mass exchange of bio-technical life support systems
Место публикации : Advances in Space Research. - 2012. - Vol. 50, Is. 7. - С. 932-940. - ISSN 02731177 (ISSN) , DOI 10.1016/j.asr.2012.05.023

Аннотация: The main obstacle to using mineralized human solid and liquid wastes as a source of mineral elements for plants cultivated in bio-technical life support systems (BLSS) is that they contain NaCl. The purpose of this study is to determine whether mineralized human wastes can be used to prepare the nutrient solution for long-duration conveyor cultivation of uneven-aged wheat and Salicornia europaea L. plant community. Human solid and liquid wastes were mineralized by the method of "wet incineration" developed by Yu. Kudenko. They served as a basis for preparing the solutions that were used for conveyor-type cultivation of wheat community represented by 5 age groups, planted with a time interval of 14 days. Wheat was cultivated hydroponically on expanded clay particles. To reduce salt content of the nutrient solution, every two weeks, after wheat was harvested, 12 L of solution was removed from the wheat irrigation tank and used for Salicornia europaea cultivation in water culture in a conveyor mode. The Salicornia community was represented by 2 age groups, planted with a time interval of 14 days. As some portion of the nutrient solution used for wheat cultivation was regularly removed, sodium concentration in the wheat irrigation solution did not exceed 400 mg/L, and mineral elements contained in the removed portion were used for Salicornia cultivation. The experiment lasted 4 months. The total wheat biomass productivity averaged 30.1 gВ·m -2В·day -1, and the harvest index amounted to 36.8%. The average productivity of Salicornia edible biomass on a dry weight basis was 39.3 gВ·m -2В·day -1, and its aboveground mass contained at least 20% of NaCl. Thus, the proposed technology of cultivation of wheat and halophyte plant community enables using mineralized human wastes as a basis for preparing nutrient solutions and including NaCl in the mass exchange of the BLSS; moreover, humans are supplied with additional amounts of leafy vegetables.

Заглавие : A database on natural and transgenic luminous microorganisms: BiolumBase
Место публикации : Microbiology. - 2005. - Vol. 74, Is. 2. - С. 236-243. - ISSN 00262617 (ISSN) , DOI 10.1007/s11021-005-0057-0
Ключевые слова (''Своб.индексиров.''): bioluminescence--database--natural and transgenic luminous microorganisms--bacteria (microorganisms)
Аннотация: The database BiolumBase was designed for the collection and systematization of available information on microorganisms containing bioluminescent systems; it includes two sections: natural and transgenic luminous microorganisms. By now, logic schemes of these sections have been developed, classification of the objects has been performed, ways of presentation of characteristics and structure of fields for input of information have been elaborated, and the necessary program modules have been developed. The database is filled on the basis of published data and our own experimental results; subsequent linkage of the database to the Internet is envisaged. Users will be able to obtain not only catalogues of strains but also information concerning the properties and functions of the known species of luminous bacteria, the structure, regulatory mechanisms, and application of bioluminescent systems and genetically engineered constructions with lux genes, as well as to find references and to search strains by using any set of attributes. The database will provide information that is of interest for the development of microbial ecology and biotechnology, in particular, for the prediction of biological hazard from the application of transgenic strains.

Заглавие : A heuristic neural network model in the research of properties of evolutionary trajectories
Место публикации : IOP Conference Series: Materials Science and Engineering: Institute of Physics Publishing, 2019. - Vol. 537: International Workshop on Advanced Technologies in Material Science, Mechanical and Automation Engineering - MIP: Engineering-2019 (4 April 2019 through 6 April 2019, ) Conference code: 149243, Is. 4. - , DOI 10.1088/1757-899X/537/4/042001
Аннотация: There is considerable data on molecular evolution, but there remains no approach to systematizing them within the framework of the key problems of biology. To search for the most common properties of evolving systems, the heuristic method has been proposed. Artificial networks of formal neurons were chosen as the heuristic model object. The paper examines the divergent component of evolutionary trajectory formation. As a result of the simulation, the dependence of the potential variability parameter on the position of the fitness function landscape was obtained. The simulation results are in agreement with the real data of molecular evolution experiments. © Published under licence by IOP Publishing Ltd.

Заглавие : A low-cost underwater particle tracking velocimetry system for measuring in situ particle flux and sedimentation rate in low-turbulence environments
Место публикации : Limnol. Oceanogr. Methods: Wiley Blackwell, 2019. - Article in press. - ISSN 15415856 (ISSN) , DOI 10.1002/lom3.10341
Аннотация: We describe a low-cost three-dimensional underwater particle tracking velocimetry system to directly measure particle settling rate and flux in low-turbulence aquatic environments. The system consists of two waterproof cameras that acquire stereoscopic videos of sinking particles at 48 frames s?1 over a tunable sampling volume of about 45 ? 25 ? 24 cm. A dedicated software package has been developed to allow evaluation of particle velocities, concentration and flux, but also of morphometric parameters such as particle area, sinking angle, shape irregularity, and density. Our method offers several advantages over traditional approaches, like sediment trap or expensive in situ camera systems: (1) it does not require beforehand particle collection and handling; (2) it is not subjected to sediment trap biases from turbulence, horizontal advection, or presence of swimmers, that may alter particulate load and flux; (3) the camera system enables faster data processing and flux computation at higher spatial resolution; (4) apart from the particle settling rates, the particle size distribution, and morphology is determined. We tested the camera system in Lake Stechlin (Germany) in low turbulence and mean flow, and analyzed the morphological properties and settling rates of particles to determine their sinking behavior. The particle flux assessed from conventional sediment trap measurements agreed well with that determined by our system. By this, the low-cost approach demonstrated its reliability in low turbulence environments and a strong potential to provide new insights into particulate carbon transport in aquatic systems. Extension of the method to more turbulent and advective conditions is also discussed. © 2019 The Authors.

Заглавие : A narrowing of the phenotypic diversity range after large rearrangements of the karyotype in salmonidae: The relationship between saltational genome rearrangements and gradual adaptive evolution
Место публикации : Genes: MDPI AG, 2017. - Vol. 8, Is. 11. - ISSN 20734425 (ISSN) , DOI 10.3390/genes8110297
Ключевые слова (''Своб.индексиров.''): ecology--evolution--genome--karyotype--morphology--ecology--gene rearrangement--genome--karyotype--morphology--nonhuman--salmonid
Аннотация: The problem of how a gradual development of ecological and morphological adaptations combines with large genome rearrangements, which have been found to occur in the phylogeny of many groups of organisms, is a matter of discussion in the literature. The objective of this work was to study the problem with the example of salmonids, whose evolution included at least six events of multiple chromosome fusions. Large karyotype rearrangements are associated with a decrease in ecological and morphological diversity in salmonids. In the above example, genome rearrangements seem to distort the function of the genetic systems that are responsible for the occurrence of certain ecological forms in salmonids. © 2017 by the authors; Licensee MDPI, Basel, Switzerland.

Заглавие : A study of the properties and efficacy of microparticles based on P(3HB) and P(3HB/3HV) loaded with herbicides
Место публикации : J. Appl. Polym. Sci.: John Wiley and Sons Inc, 2021. - Article in press. - ISSN 00218995 (ISSN), DOI 10.1002/app.51756
Аннотация: The wide use of pesticides in agriculture has caused uncontrolled distribution of these chemicals in the environment, calling for the development and investigation of new environmentally friendly formulations, which would reduce human impact on nature. In the present study, the metribuzin (MET), tribenuron-methyl (TBM), and fenoxaprop-P-ethyl (FPE) herbicides were encapsulated in microparticles of degradable microbial polymers – polyhydroxyalkanoates (PHAs) – of two types – poly-3-hydroxybutyrate [P(3HB)] and poly(3-hydroxybutyrate-co-3-hydroxyvalerate [P(3HB/3HV)]. The use of P(3HB) resulted in higher yields of microparticles (63% to 79%) and larger sizes of the particles, whose average diameter was 0.60 ± 0.06–0.75 ± 0.11 ?m, while the average diameter of copolymer particles varied between 0.43 ± 0.12 and 0.55 ± 0.05 ?m. Encapsulation efficiency was rather determined by the type of herbicide and its solubility, varying from 24.7% to 48.2%. In vitro herbicide release from microparticles to water was affected by herbicide solubility and PHA chemical composition. The readily soluble MET showed the highest release rate, and over 30 days, 64% and 78% of the encapsulated amounts were released from P(3HB) and P(3HB/3HV) microparticles, respectively. High herbicidal activity of microparticles loaded with metribuzin and tribenuron-methyl was demonstrated in the laboratory stands of the Elsholtzia ciliata weed plant. © 2021 Wiley Periodicals LLC.

Аннотация: The brightness spectra of the Krasnoyarsk and Dnepr reservoir systems are presented for various periods of their development, from the beginning of their filling to the final stage of their formation. The curves of the surface distribution of chlorophyll a, which were remotely obtained from the brightness coefficient spectra, are found to be monotonic when diatomaceous, green protococcus, and dinophyte algae dominate in the phytoplankton. In the presence of blue-green algae, the curve of the distribution of phytoplankton on the surface is essentially irregular. The irregularities range from tens to hundreds of meters with sharp gradients of the phytoplankton concentration. The negative values of the VI color index change for positive ones when the concentration of chlorophyll a of the phytoplankton in the subsurface layer Cchl > 250-270 mg/m3. This is associated with the change in the species composition of the phytoplankton from the dominating diatom forms to bluegreen algae. Copyright В© 2005 by Pleiades Publishing, Inc.

Ключевые слова (''Своб.индексиров.''): chlorophyll--data reduction--oceanography--planets--probability--satellite communication systems--biospheres--remote sensing--chlorophyll--concentration (composition)--remote sensing--satellite data--sea surface
Аннотация: Variability of chlorophyll concentration in the ocean is one of the most important components of the primary production process on the planet. To preserve the biosphere and to make appropriate use of it, it is imperative to have a deep insight into the long-term dynamics of the primary production on the planet. To investigate the dynamics of chlorophyll concentration based on satellite data, the Institute of Biophysics (Russian Academy of Sciences, Siberian Branch) has developed a geoinformation system. It was used to detect the areas in the global ocean that are quasistationary in relation to seasonal dynamics of chlorophyll concentration. Areas such as these, found in the Indian Ocean, are described in this work. These areas form the basis for the analysis of long-term dynamics of chlorophyll concentration. In these quasistationary zones systematic monitoring of phytopigment concentration is conducted by space-borne and marine craft. The work presents long-term satellite-based data on the space distribution of anomalous deviations of chlorophyll concentration in the ocean. An anomaly criterion is proposed and maps of Pacific Ocean areas with a high probability of anomalies are presented. В© 2004 Taylor and Francis Ltd.

Заглавие : A test system for tick-borne encephalitis virus detection based on bioluminescent immunoassay
Место публикации : J. Sib. Fed. Univ. - Biol.: Siberian Federal University, 2020. - Vol. 13, Is. 3. - С. 310-321. - ISSN 19971389 (ISSN), DOI 10.17516/1997-1389-0296
Аннотация: The tick-borne encephalitis virus (TBEV) is the causative agent of one of the most severe human neuroinfections. The infection transmitted by ixodid ticks is spread throughout the forest and forest-steppe zones of the temperate climatic belt of the Eurasian continent, including the Siberian region of the Russian Federation. Despite the availability of commercial analytical systems for the detection of TBEV, the task of developing approaches to a quick and reliable analysis that can be performed routinely, particularly in environmental studies, remains topical. A solid-phase bioluminescent immunoassay for determining the tick-borne encephalitis virus (TBEV) in ticks was developed. The assay is based on the hybrid protein consisting of a modified thermostable version of Renilla muelleri luciferase and a single-chain mini-antibody to protein E. This unique protein had been obtained and investigated by the authors earlier. The current study describes the expression of the hybrid protein in two different strains of recombinant E. coli cells. The optimal conditions for obtaining a highly purified protein were found. The bioluminescent reaction of the luciferase domain was triggered with the help of the stable natural form of the substrate, a Ca-dependent coelenterazine-binding protein, the recombinant variant of which was obtained by the authors. The conditions for production and storage of the immunoassay components (the hybrid protein, the stable form of the luciferase substrate, and activated microplates) were determined. Using the developed test system, more than 900 tick samples were analyzed for TBEV. In terms of sensitivity (89.5%) and specificity (98.9%), the proposed method is not inferior to colorimetric detection and is much simpler and faster than the latter. © Siberian Federal University.

Аннотация: Parameters for sample introduction, dried reagents dissolution and mixing with sample for bienzyme system NAD(H):FMN-oxidoreductase and luciferase immobilised in microfluidic chip were successfully determined. Numerical simulations of reaction chamber geometry, flavin mononucleotide (FMN) escape from starch gel and mixing options were conducted to achieve higher sensitivity of bioluminescent reaction. Results of numerical simulations were verified experimentally. The active mixer for dried reagents was made from an electro-mechanical speaker's membrane which was connected to the input of the chip. Such a mixer provided better efficiency than a passive mixing, and it is simple enough for use in point-of-care devices with any systems based on immobilised enzymes in chips.

METABARCODING APPROACH
RAPID ASSESSMENT
Аннотация: Conservation and sustainable management of aquatic ecosystems is a priority in environmental programs worldwide. However, these aims are highly dependent on the efficiency, accuracy and cost of existent methods for the detection of keystone species and monitoring of biological communities. Rapid advances in eDNA, barcoding and metabarcoding promoted by high-throughput sequencing technologies are generating millions of sequences in a fast way, with a promising cost reduction, and overcoming some difficulties of the traditional taxonomic approaches. This paper provides an updated broad perspective of the current developments in this dynamic field presented in the special session (SS) "The use of molecular tools in ecological and biodiversity assessment of aquatic ecosystems" of the XIX Congress of the Iberian Association of Limnology (AIL2018), held in Coimbra, Portugal. Developments presented are mainly focused on the Iberian Peninsula (Portugal and Spain, including Atlantic Macaronesian islands) but include studies in France, Germany, Finland, Russia (Siberia) and South America. The networks within which these researchers are involved are yet even broader, profiting from existing molecular facilities, and traditional taxonomic expertise, which can be viewed as a characteristic of this new research area. It was evident in the SS that the use of molecular tools is widespread, being used to study a diversity of aquatic systems, from rivers' headwaters to estuaries and coastal lagoons, and volcanic, mountain and frozen lakes to hot springs. The organisms targeted are likewise varied and include fish, macroinvertebrates, meiofauna, microalgae such as diatoms and dinoflagellates, other protists, fungi, and bacteria (cyanobacteria and other). Some studies address the whole biodiversity (i.e., all species present independently of the taxonomic group) from environmental samples of water, biofilms and preservative solution from field samples (e.g., ethanol from macroinvertebrate samples). Great advances were acknowledged in the special session, namely in the use of metabarcoding for detecting hidden biodiversity, juvenile stages, low-abundance species, non-indigenous species and toxicity potential, and ultimately for ecological monitoring of diatoms and invertebrates. Yet, several drawbacks were highlighted and need further work, which include: taxonomic gaps in the reference databases (including gaps at species level and on intraspecific variability) or absence of public databases (e.g. for meiofauna), still high sequencing costs, the need of a substantial bioinformatics effort, difficulties in establishing the amount of environmental sample necessary for a good DNA extraction and the need for testing different genetic markers to obtain accurate results.

Заглавие : An alternative approach to solar system exploration providing safety of human mission to Mars

Аннотация: For systematic human Mars exploration, meeting crew safety requirements, it seems perspective to assemble into a spacecraft: an electrical rocket, a well-shielded long-term life support system, and a manipulator-robots operating in combined "presence effect" and "master-slave" mode. The electrical spacecraft would carry humans to the orbit of Mars, providing short distance (and low signal time delay) between operator and robot-manipulators, which are landed on the surface of the planet. Long-term hybrid biological and physical/chemical LSS could provide environment supporting human health and well being. Robot-manipulators operating in "presence effect" and "master-slave" mode exclude necessity of human landing on Martian surface decreasing the level of risk for crew. Since crewmen would not have direct contact with the Martian environment then the problem of mutual biological protection is essentially reduced. Lightweight robot-manipulators, without heavy life support systems and without the necessity of returning to the mother vessel, could be sent as scouts to different places on the planet surface, scanning the most interesting for exobiological research site. Some approximate estimations of electric spacecraft, long-term hybrid LSS, radiation protection and mission parameters are conducted and discussed. В© 2002 COSPAR. Published by Elsevier Science Ltd.

Аннотация: This work concerns the model of a biological life support system consisting of higher plants, a unit of "biological combustion", a physicochemical reactor, and 1/30 of a human. The cycling of the main biogenic elements of the system, water, and carbon dioxide was closed to a high degree (more than 95%). Experimental-theoretical analysis of the cycling processes in the system was based on the calculations of mass exchange rates dynamics and some stoichiometric equations. The model was designed for the study of mechanisms of material transformation and the directions of mass exchange processes in the artificial ecosystems. Copyright В© 2003 SAE International.

Заглавие : Analysis of the gas exchange and water balance in a closed experimental model of the artificial ecosystem intended for an estimated portion of a human
Место публикации : Acta Astronaut: Elsevier Ltd, 2018. - ISSN 00945765 (ISSN) , DOI 10.1016/j.actaastro.2018.07.022
Ключевые слова (''Своб.индексиров.''): experimental model of a closed ecological system--higher plant community--human respiratory function--water balance--со2 and о2 gas exchange--carbon dioxide--evapotranspiration--closed ecological systems--gas exchange--higher plants--respiratory function--water balance--ecosystems
Аннотация: This study was performed to investigate water and gas exchange in the experimental model of a closed ecological system (CES) intended for an estimated portion of a human in the long-duration (several-month) experiment. The diversity of the vegetable conveyor in the system was increased. Human wastes were involved in mass exchange processes, and human respiratory function was periodically connected to the experimental model of a CES. The experimental model of a CES was used to quantify regeneration of the gaseous atmosphere with oxygen and carbon dioxide loops by linking the photosynthesizing compartment with the heterotrophic compartment (soil-like substrate) and by the periodic connection of the human respiratory function. Under the preset light and temperature conditions, atmospheric CO2 concentration in the CES model intended for a portion of a human was maintained at a level that neither limited photosynthetic processes nor was harmful to humans (800–2000 ppm) during the 154-day experiment. At the same time, O2 concentration did not either drop below 20.8% or rise above 22.6%. The amount of the evapotranspiration water collected in the system could satisfy 50% of the daily water requirement of a human (with all the water used and excreted by the human being processed and used to irrigate plants). The evapotranspiration water did not need to be additionally purified before being used by humans. Thus, in the experimental model of the closed ecological system, human oxygen and food requirements (per 0.05 portion of a human) were matched to the function of the heterotrophic compartment and the photosynthesizing activity of the multispecies uneven-aged higher plant community. © 2018 IAA

LUCIFERASE
Ключевые слова (''Своб.индексиров.''): bioluminescence--ca2+-regulated photoprotein--diagnostics--immunoassay--luciferase--nucleic acid hybridization assay
Аннотация: Nowadays luciferases are effectively used as analytical instruments in a great variety of research fields. Of special interest are the studies dealing with elaboration of novel analytical systems for the purposes of medical diagnostics. The ever-expanding spectrum of clinically important analytes accounts for the increasing demand for new techniques for their detection. In this chapter we have made an attempt to summarize the results on applications of luciferases as reporters in binding assays including immunoassay, nucleic acid hybridization assay, and so on. The data over the last 15 years have been analyzed and clearly show that luciferase-based assays, due to extremely high sensitivity, low cost, and the lack of need for skilled personnel, hold much promise for clinical diagnostics.
