Abstract:

Biosystem of the human body is viewed as a whole. First of all adequate mathematical machine selection and class of biosystems needs to be assigned for creation of mathematical model of biological system. Biosystem has two types of appoach. One of them is supposed to be a simple approach, the other is likely to be very complex – indexed approach. Different biosystems with determination properties are usually described by differential and integral equations, linear and nonlinear algebra. In some cases, algebraic polynoms with timed argument are used for presenting determined biosystem dynamics. Adequate mathematical modeling machine, probability theory, Markov and random processes theory and the laws are applied for the description of likely characterized biosystems. Key words: biosystem, biocybernetic issues, differential and integral equations, mathematical model, Markov chains, Bayes method, artifical neural networks

Abstract:

Population growth followed by an increase in laundry activity generates waste if left unchecked will cause damage to aquatic biota. To overcome this need the existence of an environmentally benign laundry water treatment system such as biosystem. Biosystem used in this research with length 180 cm width 60 cm and height 40 cm filled gravel as filter media and elephant grass (pennisetum purpureum) plant. The way of operating the biosystem is by pouring the waste into a tub of biosystem and then samples waste water taken on the biosystem output. The result treatment that biosystems combined with anaerobic reservoirs decreased BOD, COD, phosphate and detergent levels by 127.09 mg/l, 161.96 mg/l, 0.8699 mg/l and 1.3228 mg/l in a single treatment on roughing horizontal flow filter for laundry water treatment. The performance of physical and biological components in biosystems combined with anaerobic reservoir effectively decreased BOD, COD, phosphate and detergent concentrations by 73.91%, 69.58%, 58.74% and 80.03% (above 50%) in one treatment. But only in lowering the effectiveness of phosphate levels is still relatively low when compared with the effectiveness of wastewater quality standards. Further research needs to be done calculations to find plants in biosystems that can thrive. In addition, further research is needed to find the operating time until the biosystem undergoes a breaktrough condition. Keywords: laundry, waste water, biosystem.

Abstract:

Cr(VI) detoxification by biotreatment is considered one of the most practical detoxification methods, especially at low-to-medium concentrations. Although the capabilities of chromium-reducing bacteria and related enzymes in removing Cr(VI) have been explored, little is known about their differences in engineering applications. In this study, Ochrobactrum sp. CUST210-1 was isolated and its chromate reductase identified and separated as biological elements in biosystems developed for Cr(VI) removal. Results indicate that intracellular Cr(OH)3(s) accounted for 88.01% of Cr(VI) reduction product, and a possible reduction mechanism was exposed. The chromate reductase in Ochrobactrum sp. CUST210-1 was ChrR protein, and its crystal structure was revealed. The toxicity of Cr(VI)-containing wastewater was decreased by 57.8% and 67.0% (at minimum) by the CUST210-1 strain and ChrR, respectively. The Ochrobactrum sp. CUST210-1 biosystem demonstrated good adaptability to pH (7–9), and the ChrR biosystem exhibited high removal efficiency (>98.2%) at a wide range of temperatures (25 °C–40 °C). The outlet Cr(VI) concentration of the CUST210-1 biosystem met the industrial discharge limit of 0.5 mg L−1 when the inlet Cr(VI) concentration in the actual Cr(VI)-containing wastewater was <430 mg L−1. The stricter water quality standard of 0.05 mg L−1 could be complied with by the immobilized ChrR biosystem when <150 mg L−1 Cr(VI) concentration was introduced. These developed biosystems can be used in the bioremediation of various Cr(VI)-contaminated wastewaters. Regarding capital costs, those of the CUST210-1 biosystem were higher. To our knowledge, this is the first report comparing differences in the economic and operational characteristics of bacteria and enzyme biosystems for Cr(VI) removal.

Abstract:

Understanding and predicting how biosystems function require knowledge about the dynamic physicochemical environments with which they interact and alter by their presence. Yet, identifying specific components, tracking the dynamics of the system, and monitoring local environmental conditions without disrupting biosystem function present significant challenges for analytical measurements. Nanomaterials, by their very size and nature, can act as probes and interfaces to biosystems and offer solutions to some of these challenges. At the nanoscale, material properties emerge that can be exploited for localizing biomolecules and making chemical measurements at cellular and subcellular scales. Here, we review advances in chemical imaging enabled by nanoscale structures, in the use of nanoparticles as chemical and environmental probes, and in the development of micro- and nanoscale fluidic devices to define and manipulate local environments and facilitate chemical measurements of complex biosystems. Integration of these nano-enabled methods will lead to an unprecedented understanding of biosystem function.

Abstract:

This paper is our attempt, on the basis of physical theory, to bring more clarification on the question “What is life?” formulated in the well-known book of Schrödinger in 1944. According to Schrödinger, the main distinguishing feature of a biosystem’s functioning is the ability to preserve its order structure or, in mathematical terms, to prevent increasing of entropy. However, Schrödinger’s analysis shows that the classical theory is not able to adequately describe the order-stability in a biosystem. Schrödinger also appealed to the ambiguous notion of negative entropy. We apply quantum theory. As is well-known, behaviour of the quantum von Neumann entropy crucially differs from behaviour of classical entropy. We consider a complex biosystem S composed of many subsystems, say proteins, cells, or neural networks in the brain, that is, S=(Si). We study the following problem: whether the compound system S can maintain “global order” in the situation of an increase of local disorder and if S can preserve the low entropy while other Si increase their entropies (may be essentially). We show that the entropy of a system as a whole can be constant, while the entropies of its parts rising. For classical systems, this is impossible, because the entropy of S cannot be less than the entropy of its subsystem Si. And if a subsystems’s entropy increases, then a system’s entropy should also increase, by at least the same amount. However, within the quantum information theory, the answer is positive. The significant role is played by the entanglement of a subsystems’ states. In the absence of entanglement, the increasing of local disorder implies an increasing disorder in the compound system S (as in the classical regime). In this note, we proceed within a quantum-like approach to mathematical modeling of information processing by biosystems—respecting the quantum laws need not be based on genuine quantum physical processes in biosystems. Recently, such modeling found numerous applications in molecular biology, genetics, evolution theory, cognition, psychology and decision making. The quantum-like model of order stability can be applied not only in biology, but also in social science and artificial intelligence.

Abstract:

This study presents a comparative analysis of halophiles from the global open sea and coastal biosystems through shotgun metagenomes (n = 209) retrieved from public repositories. The open sea was significantly enriched with Prochlorococcus and Candidatus pelagibacter. Meanwhile, coastal biosystems were dominated by Marinobacter and Alcanivorax. Halophilic archaea Haloarcula and Haloquandratum, predominant in the coastal biosystem, were significantly (p < 0.05) enriched in coastal biosystems compared to the open sea. Analysis of whole genomes (n = 23,540), retrieved from EzBioCloud, detected crtI in 64.66% of genomes, while cruF was observed in 1.69% Bacteria and 40.75% Archaea. We further confirmed the viability and carotenoid pigment production by pure culture isolation (n = 1351) of extreme halophiles from sediments (n = 410 × 3) sampling at the Arabian coastline of India. All red-pigmented isolates were represented exclusively by Haloferax, resistant to saturated NaCl (6 M), and had >60% G + C content. Multidrug resistance to tetracycline, gentamicin, ampicillin, and chloramphenicol were also observed. Our study showed that coastal biosystems could be more suited for bioprospection of halophiles rather than the open sea.

Abstract:

идентификация стационарных режимов (неизменности) биосистем в биокибернетике приобрела критическое значение после открытия эффекта Еськова–Зинченко. В этом эффекте доказано отсутствие статистической устойчивости любой выборки любого параметра функций организма человека. Если любая выборка статистически уникальна, то статистика не работает и нет тогда способов наблюдать неизменность биосистемы (она находится в непрерывном хаотичном движении). В работе предлагается рассчитывать числа k пар (в таблицах парных сравнений выборок), которые статистически могу иметь общую генеральную совокупность. Одновременно обращается внимание на то, что площади псевдоаттракторов в двумерных фазовых пространствах состояний тоже могут быть инвариантами (при неизменном физиологичном состоянии биосистемы). the study of steady-state modes (invariability) in biosystems through biocybernetics research is paramount in the light of the Eskov–Zinchenko effect. The effect is statistical instability of any human body property. If any sample has unique statistical properties, then the statistical approach does not work and we cannot observe the invariability of the biosystem (it is in a continuous, chaotic movement). This work proposes to estimate k pairs of numbers (using pairwise comparisons of the samples), which statistically may have a general distribution. It is also emphasized that the areas of pseudoattractors in the two-dimensional phase state spaces can also be invariants (for an unchanged physiological state of the biosystem).

Abstract:

AbstractTaq polymerase system is one of the key success factors for genotyping by using semi-random marker types. Start codon targeted (SCoT) and sequence-related amplified polymorphism (SRAP) are semi-random markers that amplify more than one target at a time, like in multiplex PCR. Here, we compared the performance of five multiplex PCR kits (QIAGEN®, Thermo Scientific™, New England Biolabs, KAPA Biosystem and iNtRON Biotechnology) and Taq DNA polymerase from Vivantis as a representative common Taq polymerase. The PCR using three SCoT and three SRAP markers was performed in six plants, which were different in genome size, including three monocotyledons (rice, oil palm and onion) and three dicotyledons (holy basil, chilli pepper and eggplant). The overall results demonstrated consistent high performance of the Taq polymerase system with the multiplex PCR kit from KAPA Biosystem. Considered by plant, the multiplex PCR kit from KAPA Biosystem showed the best performance in holy basil, eggplant, oil palm and chilli pepper, whereas in rice, the Taq DNA polymerase from Vivantis generated better results than the KAPA Biosystem. In onion, multiplex PCR kit from Thermo Scientific™ showed the best performance among those tested, even if it did not perform well in the other plans. Different Taq polymerase systems might generate different band patterns, therefore using the same Taq polymerase system within one experimental dataset is recommended. The multiplex PCR kit from KAPA Biosystem is the best starting choice.

Abstract:

Abstract The purpose of this study was to determine the possibility of practical use of the Hackathon Platform for ecological protection of the university biosystem to prevent a new outbreak of the COVID-19 pandemic. The COVID-19 pandemic significantly affects companies and population’s behaviour. The most significant change occurred in the attitude of companies to the environment from technical and technological points of view. To increase their production sustainability, these companies are looking at the possibilities of waste recovery through sustainable recycling, or recovery of waste as a source of secondary raw material. One of the simplest ways is to use agricultural waste for energy purposes, bringing bioenergy to the forefront as a new area of Industry 4.0. The ALARA model was used to assess the quality of six biosystem components (atmospheric air, water resources, soil layer, the level of land pollution with chemicals and littering by the unauthorized dumps; sufficient volume of green planting on the territory). This allowed the development of management decisions and environmental protection measures based on the system of calculated indicators of potential environmental damage for each of six biosystem components. The forecast of plan implementation: the quality of four from among six biosystem components (atmospheric air, water resources, soil layer, sufficient volume of green planting on the territory) will increase on average by 30–40%. A minor improvement in the quality of the other biosystem components (approx. by 10%) raises concerns about the high probability of a new outbreak of the COVID-19 pandemic.

Abstract:

We utilized an ecosystem model and life cycle assessment tool for studying carbon flows between the ecosystem, technosystem, and atmosphere for scenarios utilizing forest biomass (biosystem) against fossil fuel intensive materials (fossil system). The net climate impacts were studied for a Norway spruce (Picea abies (L.) Karst.) stand over two consecutive rotation periods (2 × 80 years) in the boreal conditions in central Finland (62°N, 29°E). The effects of alternative forest management on the carbon dynamics in the biosystem were studied in comparison with the fossil system by using an unmanaged and baseline thinning regime. The results showed that the biosystem produced carbon benefits compared with the similar system with the use of fossil fuel intensive materials and energy. The unmanaged stand stored the highest amount of carbon and retained carbon the longest when solely the ecosystem was considered. Studying the ecosystem and the technosystem together, the biosystem was found effective in storing and increasing the residence of carbon with or without changing the life span of biomass-based products. We found that the increase of the life span of biomass-based products could reduce emissions up to 0.28 t CO2·ha−1·year−1 depending on the management regimes over the study period. The increased stocking regimes could increase negative net climate impact by 47% over the study period compared with the use of baseline thinning in the biosystem. The proper climate mitigation strategies should consider the benefits from forest management and forest biomass in storing carbon into both the ecosystem and technosystem.

Full text

Abstract:

We consider systems of differential equations with polynomial and rational nonlinearities and with a dependence on a discrete parameter. Such systems arise in biological and ecological applications, where the discrete parameter can be interpreted as a genetic code. The genetic code defines system responses to external perturbations. We suppose that these responses are defined by deep networks. We investigate the stability of attractors of our systems under sequences of perturbations (for example, stresses induced by environmental changes), and we introduce a new concept of biosystem stability via gene regulation. We show that if the gene regulation is absent, then biosystems sooner or later collapse under fluctuations. By a genetic regulation, one can provide attractor stability for large times. Therefore, in the framework of our model, we prove the Gromov–Carbone hypothesis that evolution by replication makes biosystems robust against random fluctuations. We apply these results to a model of cancer immune therapy.

Full text

Abstract:

Microbial enhanced oil recovery is considered to be one of the most promising methods of stimulating formation, contributing to a higher level of oil production from long-term fields. The injection of bioreagents into a reservoir results in the creation of oil-displacing agents along with significant amount of gases, mainly carbon dioxide. In early, the authors failed to study the preparation of self-gasified biosystems and the implementation of the subcritical region (SR) under reservoir conditions. Gasified systems in the subcritical phase have better oil-displacing properties than non-gasified systems. Because, in a heterogeneous porous medium, the filtration profile of gasified liquids in the SR should be more uniform than for a degassed liquid. Based on experimental studies, the superior efficiency of oil displacement by gasified biosystems compared with degassed ones has been demonstrated. The possibility of efficient use of gasified hybrid biopolymer systems has been shown. Keywords: self-gasified; biosystem; microbial; subcritical region; slippage effect; enhanced oil recovery.

Abstract:

любое моделирование процессов, в том числе биологических, базируется на закономерностях, происходящих как внутри, так и снаружи объекта моделирования. Изучение динамики поведения сложных биосистем позволило установить некоторые закономерности, которые осложняют возможность эффективно моделировать динамику тех или иных параметров тем, что подобные системы обладают хаотической, самоорганизующейся структурой. В биосистемах нет возможности повторить начальное xi, любое промежуточное xn и конечное xk состояния как системы в целом, так и любой отдельной подсистемы. В этой связи моделирование сложных биосистем должно базироваться на хаотических закономерностях. Созданная математическая модель позволяет максимально точно моделировать движение конечности человека в двумерной плоскости. В основу математической модели положены три принципа: во-первых, включение регуляторных механизмов модели осуществляется на основе теории дифференциальных уравнений с разрывной правой частью; во-вторых, траектория удержания конечности в пространстве (моделирование тремора человека) изменяет свое направление случайным образом в ограниченном диапазоне, что позволяет решить проблему моделирования системы с самоорганизующейся структурой; в-третьих, все изменения биосистемы происходят на основе случайных чисел. Созданная математическая модель является масштабируемой, что позволит в дальнейшем привести ее к трехмерному варианту с возможностью изменять количество мышечных пучков, задействованных в движении конечности человека. any simulation of processes, including biological ones, follows the patterns occurring both inside and outside of the object. The study of complex biosystem dynamics identified some such patternswhich complicate the simulation of system parameter dynamics since such systems have a chaotic, selforganizing structure. In biosystems, it is impossible to reproduce the initial xi, any intermediate xn and final xk states of both the entire system and any subsystem. Simulation of complex biosystems should consider chaotic patterns. The proposed simulation model accurately represents the 2D movement of a human limb. The model implements three principles: the regulatory circuits of the model are represented by differential equations with discontinuous right-hand side; the limb trajectory (tremor simulation) direction is changed randomly in a limited range to simulate a self-organizing system; any changes to the biosystem are random. The model is scalable and can be applied to a 3D study with more muscle bundles controlling the movement of a human limb.

Abstract:

Maltose is a natural α-(1,4)-linked disaccharide with wide applications in food industries and microbial fermentation. However, maltose has scarcely been used for in vitro biosynthesis, possibly because its phosphorylation by maltose phosphorylase (MP) yields β-glucose 1-phosphate (β-G1P) that cannot be utilized by α-phosphoglucomutase (α-PGM) commonly found in in vitro synthetic enzymatic biosystems previously constructed by our group. Herein, we designed an in vitro synthetic enzymatic reaction module comprised of MP, β-phosphoglucomutase (β-PGM), and polyphosphate glucokinase (PPGK) for the stoichiometric conversion of each maltose molecule to two glucose 6-phosphate (G6P) molecules. Based on this synthetic module, we further constructed two in vitro synthetic biosystems to produce bioelectricity and fructose 1,6-diphosphate (FDP), respectively. The 14-enzyme biobattery achieved a Faraday efficiency of 96.4% and a maximal power density of 0.6 mW/cm2, whereas the 5-enzyme in vitro FDP-producing biosystem yielded 187.0 mM FDP from 50 g/L (139 mM) maltose by adopting a fed-batch substrate feeding strategy. Our study not only suggests new application scenarios for maltose but also provides novel strategies for the high-efficient production of bioelectricity and value-added biochemicals.

Abstract:

Biosystem engineering is a discipline resulting from the evolution of the traditional agricultural engineering to include new engineering challenges related with biological systems, from the cell to the environment. Modern buildings and infrastructures are needed to satisfy crop and animal production demands. In this paper a review on the status of numerical methods applied to solve engineering problems in the field of buildings and infrastructures in biosystem engineering is presented. The history and basic background of the finite element method is presented. This is the first numerical method implemented and also the more developed one. The history and background of other two more recent methods, with practical applications, the computer fluids dynamics and the discrete element method are also presented. Besides, a review on the scientific and professional applications on the field of buildings and infrastructures for biosystem engineering needs is presented. Today we can simulate engineering problems with solids, engineering problems with fluids and engineering problems with particles and get to practical solutions faster and cheaper than in the past. The paper encourages young engineers and researchers to make progress these tools and their engineering applications. The capacities of all numerical methods in their present development status go beyond the present practical applications. There is a broad field to work on it.

Abstract:

In the present article the authors discuss the possibility of increasing of the suitability of milk as a raw material for cheese production through preservation of native properties of milk proteins, in the first place biologically complete whey proteins as well as the weight ratio of total and ionic calcium. For thermodynamic evaluation of the biosystem we used activation energy (Ea), chemical, physical and organoleptic characteristics. As a result: a methodology has been developed for determination of foodstuffs activation energy; it was determined that with increase in the proportion of the pectin introduced the activation energy and structuredness of the biosystem also increases, when the proportion of pectin is 0.5% the activation energy is 1.788 kJ/mol, when the proportion of pectin is 3% the activation energy is 2.241 kJ/mol, which means the increase by 25%; in the studied pasteurization standard, the maximum content of calcium is observed at 85oC and is equal to 133.8 mg%., in the control sample of milk the content of calcium is 130 mg%; addition of a complex food additive as a protector makes it possible to preserve native properties of the biosystem and guarantees formation of a denser protein coagulum which allows producing high-quality fermented milk products and cheeses.

Abstract:

Informational Macro Dynamics (IMD) contains formal mathematical and computer methodology to describe transformation of random information processes (at microlevel) into system dynamic processes (at macrolevel) to model the observed processes on the basis of both discovery of their information dynamic regularities, and the identification of macro dynamic equations. Informational description of interactions includes not only physical connections between the processes, but also the information superimposition of processes of different nature with transferring information from one interacting process to others and creating the information defect. The synthesized optimal macro dynamics gives rise to self-organized structures, becoming ordered in the process of optimal motion. The macro model's systemic mechanisms have similarities with the biosystemic functional activities. This paper introduces the concrete biological examples of the constructive IMD model applications for analysis and discovery of some important biosystem mechanisms, functions and phenomena.

Abstract:

The directional asymmetry in the birch leaf plates was studied. For this purpose, ten randomly selected populations were used in the Vladimir region (Russia). The leaf plates were photographed twice, 5 pairs of bilateral-symmetric labels were used and Procrustes analysis of variance carried out. Directional asymmetry testing was carried out at three biosystemic levels (population, individual and leaf plate level). The totality of all populations did not show the presence of directional asymmetry. Biosystemic level – “tree” had a statistically significant directional asymmetry in 4 populations. At the level of “leaf plate” biosystem, directional asymmetry was found in 9 populations among 10. Thus, only one population had a fluctuating asymmetry at all biosystemic levels (p <0.0001). The directional asymmetry of the linear features was checked in the t-test and was statistically significant only in two populations. Thus, directional asymmetry is the usual kind of asymmetry, present in the form of birch leaf plates which are pendant under conditions of normal variability. The described fact related specifically to the leaf plate, as to the unit of measurement. Therefore, in determining the FA and HA of leaf plates, one must keep in mind the possible presence of directional asymmetry as a population characteristic.

Abstract:

Today the formalization of the description of the evolving system doesn’t exist in biology. But if a biosystem is described by a state vector x=x(t)=(x1, x2, …, xm)T in multidimensional phase space, notions of speed and acceleration for the description of quasi-attractor’s motion can be introduced. Vector x(t) moves constantly and chaotically inside the quasi-attractor, i.e. dx/dt≠0 is constant. With age these quasi-attractors show translational motion in phase space for which the model as an dx/dt=(a-bx)x is created and speed V=dx/dt and acceleration a=dV/dt are determined for evolution of biosystems. The current paper presents concrete examples of age-related changes of quasi-attractor’s parameters (two-dimensional phase space) that should be considered as an evolution of vector of cardiorespiratory system in six-dimensional phase space. Models of such dynamics are discussed according to quasi-attractor’s parameters that allow to calculating speed and acceleration of evolution in some integrative values.

Full text

Abstract:

Photobiomodulation (PBM) is a nondamaged modulation of laser irradiation or monochromatic light (LI) on a biosystem function. It depends on whether the function is in its function-specific homeostasis (FSH). An FSH is a negative-feedback response of a biosystem to maintain the function-specific conditions inside the biosystem so that the function is perfectly performed. A function in its FSH is called a normal function. A function far from its FSH is called a dysfunctional function. The process of a function from dysfunctional to normal is called a functional normalization. For a normal function in its FSH, there are FSH-essential subfunctions (FESs), FSH-nonessential subfunctions (FNSs), and an FES/FNS-specific homeostasis (FESH/FNSH). A FSH can resist internal/external disturbances under the threshold, but can be disrupted by an FSH-specific stress (FSS). A normal/dysfunctional FSS is called a successful/chronic stress. An FESH/FNSH-specific stress was called an extraordinary/ordinary stress. A low level LI (LLL) cannot directly affect a normal function, but can modulate a chronic stress. A normal function may have a chronic ordinary stress, and an LLL may modulate the chronic ordinary stress so that it promotes the normalization of the dysfunctional FNS and then upgrades the normal function. A high level LI can modulate a normal function and may be a successful stress.

Abstract:

The most informative parameters of woody plants living condition are analyzed, which should be used for ecological monitoring of urbanized and oil-contaminated areas. The reactions of the plant organism at different levels of the biosystem organization in response to the action of priority pollutants of the technogenic-transformed environment - heavy metals and oil products - are given. The relevance of the study of oil pollution as one of the main environmental problems of today is substantiated. Adaptive-protective reactions characteristic of resistant plant species and destructive changes in stress-sensitive phytoobjects are highlighted. It is established that the widest range of plant reactions to man-made environmental influences can be found at the molecular, cellular and organ levels of biosystems organization. Based on a set of morphological, physiological, cytological, histological and phenological processes of plants, it is recommended to use indicator species in biomonitoring studies, and remediative species - in reclamation measures of anthropogenically altered areas. Methodical approaches to the assessment of the ecological condition of urbanized and oil-contaminated ecosystems, based on the specifics of zoning and the choice of background area, are highlighted. The classes of vitality and the categories of plant stability are characterized on the basis of the percentage deviation of the analyzed plant parameters with the background values. The prospects of green plantations as primary producers of organic matter and recipients of complex influence of biotic, abiotic and anthropogenic environmental factors are substantiated. The criteria for sampling plant material for bioindication studies in order to obtain reliable factual data are described. The relationship between the processes that occur at all levels of the biosystem hierarchy of the plant organism - from molecular to ecosystem – is highlighted. Based on the establishment of the living condition of green areas of urbanized and oil-contaminated areas, it is possible to timely record the slightest changes in the ecological state of the environment and prevent further negative trends in it.

Abstract:

This paper discusses the design goals and the first developments of Proto-Plasm , a novel computational environment to produce libraries of executable, combinable and customizable computer models of natural and synthetic biosystems, aiming to provide a supporting framework for predictive understanding of structure and behaviour through multiscale geometric modelling and multiphysics simulations. Admittedly, the Proto-Plasm platform is still in its infancy. Its computational framework—language, model library, integrated development environment and parallel engine—intends to provide patient-specific computational modelling and simulation of organs and biosystem, exploiting novel functionalities resulting from the symbolic combination of parametrized models of parts at various scales. Proto-Plasm may define the model equations, but it is currently focused on the symbolic description of model geometry and on the parallel support of simulations. Conversely, CellML and SBML could be viewed as defining the behavioural functions (the model equations) to be used within a Proto-Plasm program. Here we exemplify the basic functionalities of Proto-Plasm , by constructing a schematic heart model. We also discuss multiscale issues with reference to the geometric and physical modelling of neuromuscular junctions.

Abstract:

Studying the embryo development at an early stage is considered. For this, hyperspectral imaging using an acousto-optical microscope-based system is proposed. Acousto-optic visualization of the early developmental stages of the loach Misgurnus fossilis embryo showed a regular change in the spectral characteristics of different image areas corresponding to the tissues and body fluids, depending on the functional state of the embryo. We show that there is a discrete set of maxima in the optical absorption spectrum with a distance of 20 nm and 30 nm between them. Value 20 nm corresponds to the normal development of biological tissue. The appearance of the value 30 nm between the maxima of neighboring optical absorption bands indicates the development of pathological processes in the biosystem. Such deviations from the norm are characteristic of germinal tissues, and they are absent in the perivitelline fluid. Thus, we demonstrated that for the early diagnosis of the physiological state of a developing biosystem, special attention should be paid to optical absorption spectra.
