The main aim of this study was to evaluate physiological and growth-associated drought tolerance responses of mycorrhiza inoculated T. aestivum L., cv. Chamran seedlings with G. mosseae in flag leaves and roots. The arbuscular mycorrhizal (AM) or non-AM wheat seedlings under normal or water-stressed conditions were assessed for growth parameters, relative water content(RWC), solute aggradation, lipid peroxidation, and enzymatic and non-enzymatic antioxidants. Outcomes reflected the enhancing influence of AM on seedlings under drought stress: mycorrhization of zero and 32.25% in non-AM and AM seedlings, respectively, fresh weight and dry weight of shoots (28.5 and 27.34%, respectively) and roots (28.86 and 31.68%, respectively), RWC (55.15%), phosphorus concentration in shoots and roots (69.25 and 95.36%), total soluble protein and carbohydrate content in shoots (52.63 and 15.80%, respectively) and roots (30.65 and 9.80%, respectively), catalase (28.66 and 31.43%), superoxidase dismutase (28.44 and 15.27%), glutathione reductase (44.62 and 18.84%), ascorbate peroxidase (15.58 and 39.49%) and reduction in proline accumulation of shoot and root (45.01 and 44.03%) and lipid peroxidation (52.27 and 57.26%) by comparison to non-inoculated stressed seedlings. Photosynthetic pigments including chlorophyll a (77.28%), chlorophyll b (51.70%), chlorophyll total (66.76%), and carotenoid (51.75%) and antioxidative secondary metabolites such as total phenolic compounds (36.25%), total flavonoid content (30%) and total anthocyanin content (29.52%) additionally increased in flag leaves of waterstressed AM plants. Taking into account all the results of this study, it can be concluded that AM inoculation of wheat plants may considerably alleviate the harmful effects of water deficit stress.

The spleen loss leads to increase the risk of sepsis, pyelonephritis, pneumonia, and pulmonary embolism throughout the lifetime of patients with splenic trauma. Regarding the sensitivity of the spleen and the importance of appropriate therapies for spastic trauma, this study aimed to determine the consequences of spinal trauma based on different therapeutic methods. This retrospective cohort study was conducted on the splenic trauma patients who were referred to Rasool Akram Hospital in Tehran, Iran, during 2011-2017. All medical records of 133 splenic trauma patients were gathered from 2011-2017. The data were gathered related to ultrasound, and computed tomography scan or other diagnostic methods of the patients admitted in the surgical ward. Finally, splenic trauma patients with a surgical approach were compared to the subjects with a non-surgical approach. Surgical and non-surgical approaches were performed on 80% (n=104) and 20% (n=26) of the subjects, respectively. There was a significant difference between the two groups regarding the length of intensive care unit stay and total hospitalization duration. The comparison between the two groups showed that there was no significant difference in term of the related side effects (P>0.05). Overall, 80.8% (n=84) and 96.4% (n=27) of the patients were discharged in surgical and non-surgical groups, respectively. In addition, 19.2% (n=20) and 3.6% (n=1) of the cases died in surgical and non-surgical groups. The comparison of survived patients showed that there was a significant difference between the groups (P=0.045). This study showed that there was no difference regarding the consequences of surgical and non-surgical approaches in patients with splenic trauma. The length of hospital stay was shorter in the non-surgical group, compared to that of the surgical group. The most commoncause of trauma in both groups was car accidents. Retroperitoneal hematoma was the most common intraabdominal trauma. The mortality rate was higher in the surgical group in comparison to that of the non-surgical group.

According to the Federal service for drug control in Russia, currently, 8.5 million people take drugs, including marijuana-6.2 million, synthetic drugs-1.5 million, and heroin-800,000 people. According to foreign and domestic literature, the population's consumption of narcotic drugs is continuously growing, especially in the youth and adolescence: in the structure of drug addicts, 20% are patients aged 9-16 years, 60% - 17-30 years, 20% - 30 years and older. Besides, many authors note the fact that even in young people with short-term use of methadone sharply increases the intensity of dental caries with subsequent rapid loss of teeth. Since 2005, the WHO has included the drug methadone in the list of essential medicines for the treatment of opioid dependence. However, according to the latest literature, the negative effect of methadone on the body as a whole, and dental health is much more pronounced than when taking heroin. Changes in the oral cavity when taking heroin and methadone in the literature are not covered enough, so it is considered relevant to study dental pathology in this group of patients. This article presents the results of a comparative analysis of the adverse effects of heroin and methadone on the hard tissues of the teeth of drug-dependent patients. In patients taking heroin and methadone, there was a deterioration in dental status indicators. The main manifestations of taking narcotic drugs are the development of the carious process, inflammatory diseases of the oral cavity, violation of salivation, the formation and spread of chronic odontogenic infection. The negative effect of methadone is more pronounced in comparison with heroin due to the contact of the tablet form of the drug with the oral mucosa.

The influence of temperature and rainfall on nutrient levels, heavy metals, and etiologic agents in sludge samples collected at the Sewage Treatment Station of Juiz de Fora, Minas Gerais, Brazil, was verified over 24 months. The results showed high levels of nitrogen (4.7-5.2%), phosphorus (1.4-2.2%), potassium (0.076-0.106%), magnesium (0.113-0.386%), iron 5.03%) and zinc (38.2-6902.1 mg Kg-1). For most of the investigated samples, the concentration of zinc was above the maximum allowed value (2,800 mg Kg-1). The concentrations of arsenic, cadmium, chrome, copper, and lead were below the maximum values allowed by the legislation. Parasitological analyzes identified thermotolerant coliforms (0.49-160 NMP g-1) and helminth eggs (1 egg), however, in amounts less than allowed by legislation. These results are indicative of the efficiency of the sewage treatment process. The results showed a significant influence of the meteorological parameters on the concentrations of nitrogen, copper, lead, zinc and pathogens in the sludge. The results also showed a strong correlation between the concentrations of copper, lead and zinc indicating that the presence of these elements in the sewage sludge has a common origin. The results demonstrated the feasibility of using the investigated matrix as fertilizer when collected in rainy periods when it favors the dilution of the elements present in their soluble forms.
STUDY OF THE IN VITRO LIPOPROTEIN PLASMASORPTION AND PHYSICOCHEMICAL PROPERTIES OF POLYMERIC SORBENTS WITH SUBSTITUTED AMINO GROUPS
Authors: DORSKAIA Elena Vladimirovna , PESTOV Sergei Mihaylovich
Published: August 2021

Currently, the plasmasorption method is widely used in clinical practice to remove excessive amounts of metabolites that cause various pathologies. However, the plasmasorbents applied often can give a number of side effects for the patient, such as the blood clotting, the release of dust particles, and the sorption of useful components from the plasma. Besides that, they can be quite expensive. The aim of the work was to create available plasmasorbents with a good hemocompatibility for the lipoprotein adsorption from the plasma. A number of anion exchangers with groups of trimethylamine, monoethanolamine, and triethanolamine were synthesized. For the sorbents obtained, adsorption and physico-chemical properties were investigated. Bulk density, specific volume at swelling, the swelling coefficient in various solvents (water, ethanol, isopropanol, propylene glycol, acetone) were determined and the theoretical calculations of total exchange capacity and crosslinking mass and molar fractions were made. It was found that the best swelling is achieved in propylene glycol. For the sorbents LP27 and LP29, the capacities on triglyceride and lipoprotein fractions and the coefficient of distribution of lipid profile components between the solid and liquid phases were determined. It is shown that both sorbents have good sorption properties, the sample LP29 being quite promising for the lipid profile components extraction. The developed sorbents are assumed to be cheaper than currently used ones as they are synthesized on the basis of commercially available matrix. The results obtained are expected to be useful for further investigations aimed at the modern plasmasorption technology quality improvement.

The study was performed to find an association between some cytokine status indicators, level of vascular endothelial growth factors, and vitamin D in women with infertility and external genital endometriosis (EGE) in order to increase the effectiveness of treatment of this pathology. The low vitamin D status in the dynamics was determined in 240 patients aged 25 to 35 years with EGE planning pregnancy by determining the level of 25 (OH) D in the blood serum using the chemiluminescent method. Interleukin status (IL-1β, IL-6, IL-4), TNF-α, VEGF-R1 in blood serum were determined using enzyme-multiple immunoassay. The results of the studies revealed an increased level of IL-6, IL-1β, and TNF-α in groups with low vitamin D content. In normal vitamin D significantly lower levels of vascular endothelial growth factor (VEGF-R1) in the blood serum were registered. Pregnancy rates were higher in groups with normal 25 (OH) D levels in the blood serum. The mean serum VEGF-R1 level in pregnant women who became pregnant on their own was 1.3-1.5 times lower.

Metals that contain nanomaterials have the potential to be employed in controlling different kinds of infection, however, very limited information is known about their antibacterial properties. This study has been done to investigate the nanosynthesis titanium nanoparticles (TiNPs) using Streptococcus thermophilus and analyzing their biological actions as antibacterial. The bacterial isolates identified using universal primers 16S rRNA; then the 16S rRNA gene nucleotide sequences were aligned with the nucleotide sequences of strains obtained from the GeneBank through the software CLUSTAL X (version 1.82). Titanium nanoparticles were nanosynthesized by adding 0.025M titanium dioxide (TiO2) into cell-free supernatant for Streptococcus thermophilus. TiO2 was used as a precursor for nanobiosynthesis TiNPs. The formation of TiNPs was indicated
by the color alteration of the solution from the light brown into dark brown indicates for the production of TiNPs. The Characterization of nanobiosynthesis was accomplished with UV-Visible (absorbance at 377nm), Scanning Electron Microscope, X-ray diffraction, Atomic Force Microscope, Energy-dispersive X-ray spectroscopy was used to distinguish the dimension, form (spherical) by SEM, dispersal (homogenous) and elemental analysis of nanoparticles. Biogenic TiNPs have displayed antibacterial and antibiofilm activity against both multidrugresistant Klebsiella pneumonia and Staphylococcus aureus. As an antibacterial activity, the TiNPs inhibited significantly K.pneumoniae (20 mm) with concentration (500 μg/ml), and S. aureus (16 mm) with the same concentration and increasing the concentration of TiNPs the inhibition zone increased. While as antibiofilm activity of TiNPs using the tube method, the tubes containing bacterial suspension K.pneumoniae and S.aureus with TiNPs, the results demonstrated that the biofilm formation was prevented and removed by the effect of TiNPs.

Nowadays, a large number of methods for solving inverse problems arising in electrodynamics and acoustics have been developed, but the development of practical systems is necessary to combine a large number of equations that contribute to the substantiation of numerical methods for solving various multidimensional problems. Therefore, the main goal of the work is a comparative analysis of statistical methods for solving the one-dimensional inverse acoustic problem, as well as in the search for acoustic resistance. To achieve this goal, the means of description and comparison, which contributed to the identification of the characteristics of acoustic impedance, were used. Also, the finite-difference solution method, the differential circuit circulation method, and the Landweber iteration method were used. It was established that the inversion method of the difference scheme is expedient to apply in the case when additional information is known accurately enough, and the reconstructed solution is quite smooth. It was determined that if one of these conditions is violated, the method of reversing the difference scheme becomes unstable. The problems of the correctness of the issues for the wave equation with complex velocity in the one-dimensional and spatial cases were investigated. Formulas for solving these problems were obtained – analogs of classical formulas. Numerical computations show the kind of results that may be expected from the method under consideration. The materials of the paper imply the practical significance for the university teachers of the information technology specializations.

In recent years, much attention of developers of integrated microcircuits is given to designing novel types of microprocessors, development, and mastery of technologies of both multilayer 3D integrated circuits and making devices based on complex semiconductors. The aim of the present work is to study thermal processes in the Al-Ti-Si multilayer system up to the development of degradation processes. The degradation issues in aluminum metallization with titanium sublayer deposited onto silicon surface are considered. The evolution of processes of irreversible destruction of film conductor under passage through it of single square-wave current pulses with energy up to 300 mJ and duration of 50…1000 μs was analyzed. It was found that, under the action of a single square-wave current pulse with a duration of no more than 80 μs and energy of 85 mJ, the priority process of structural damage is the melting of the metal film. Increasing pulse duration (τ > 80 μs) changes the priority of thermal degradation, and contact melting becomes the main mechanism of structure damage. It was also found that isothermal annealing leads to improving system heat-conducting properties and increasing critical current densities. This is related to the improvement of adhesion properties of the structure as well as with phase transformations in the Al-Ti-Si system in the course of annealing. The results of the article can be used in further studies of the properties of the AI-TI-SI system, as well as in the creation of semiconductor structures taking into account properties such as high electrical conductivity, good processability, the absence of chemical components in the Al-Si system, chemical stability, and a tendency to electromigration, the possibility of short circuit, high diffusion mobility, low melting point, the inability to attach the wire by soldering.

Proper organization of storage of raw sugar products allows for a long time to maintain product quality and minimize loss of its mass. Difficulties are associated with the high content of free water in them. We have studied the effect of ozone treatment on long-term storage of raw sugar products, including sugar beets. Sugar beet samples were taken from the Koksu sugar factory in the village of Balpyk bi, Almaty region of the Republic of Kazakhstan. The plans for full-factor experiments of the type — 23 out of eight prototypes — were drawn up and each of them was processed with different combinations (max and min) of the following factors: x1 - ozone concentration (g/m3), x2 - processing time (min), x3 - overpressure (ati) (the pressure value can be counted from 0 (absolute pressure) or from atmospheric (overpressure). If the pressure is measured in technical atmospheres, then absolute pressure is denoted as ata, and excess pressure is denoted as ati). Physicobiochemical, microbiological properties, and safety indicators were determined for each sample of sugar beet: mass fraction of moisture, dry matter, acidity, pectin, fiber, sucrose, nitrite, heavy metals, pesticides, mycotoxins, the presence of mold and yeast. As a result of the study, it was found that ozone treatment significantly reduces the growth of mold and yeast, contributes to an increase in the content of pectin, fiber and sucrose, and a safety risk assessment of raw sugar products was scientifically provided.

Organochlorine insecticides are still exploited among the most prominent pesticides for plant protection purposes. Known for having hazardous to humans and persistent in the environment properties, it is necessary to build an accurate method for detecting organochlorine insecticides in food and environmental substances. Isotope-dilution gas chromatography-mass spectrometry (ID-GC-MS) is a versatile coupling measurement system and high order method that combines both selectivity, sensitivity and high accuracy. The present paper aims at showing the methodology of the organochlorine insecticides (alpha-HCH and gamma-HCH) determination in ginseng by using ID-GC-MS. The described method covered sample preparation using an organic solvent (hexane) extraction, followed by florisil cleaning-up. After the reconstitution of the solvent base, the measurement was conducted by using ID-GC-MS in the optimal instrument parameter. Using the determined optimal conditions, the parameters such as sensitivity, linearity, precision, and accuracy were studied for validation of the ID-GC–MS method. The limit of detection and the limit of quantitation of the instrument were 0.5 ng/g and 2.0 ng/g for both analytes. The method showed linearity with the correlation coefficient of 0.999 for both alpha-HCH and gamma-HCH over the concentration range of 1‒300 ng/g. The precision ranged from 3.0 to 3.7% and 2.4 to 3.3% for alpha-HCH and gamma-HCH, respectively. The mean recoveries for alpha-HCH and gamma-HCH were found at 98.0 and 95.6%, respectively. Following method validation, the measurement uncertainty of the alpha-HCH and gamma-HCH determination was evaluated according to EURACHEM GUM guide at a 95 % confidence level (k = 2). The expanded uncertainty in the measurement of alpha-HCH and gamma-HCH was 5.4% and 8.2%, respectively. All these parameters demonstrate the high sensitivity of the offered method and the success of the described method in the determination of alpha-HCH and gamma-HCH in ginseng sample.

The national project Trinity of Languages announced in Kazakhstan has brought forward multilingual education throughout the country. The project requires the implementation of rigorous learning tools to master the Kazakh, Russian and English languages within trilingualism. An e-dictionary to be used in content and language integrated learning is among modern e-tools promoted in a trilingual school environment. A user-friendly biological e-dictionary will help high school learners grasp fundamental concepts in natural sciences. The article aims to describe how to analyze and systemize the lexicographic material selected for developing a trilingual e-dictionary of biological terms for Kazakhstani school learners. Determining sources of vocabulary chosen was based upon a linguocultural approach, which highlights the cultural aspect embodied in the language, and mind-mapping, which allows deconstructing complex topics graphically. Twenty-eight items were selected to cover the biology school course, which was later analyzed and systemized to consistently present generic and species features via mind-mapping. Then organic unification of the items and compositional parameters of the e-dictionary were determined. The obtained findings show that a linguocultural component is embedded in a trilingual e-dictionary of biological terms that are taken from relevant Kazakh and Russian school textbooks (grades 6–11). The selected items are classified and subject to linguocultural analysis in conceptual groups which may show phytonyms and zoonima. The items are supplied with an adequate linguocultural commentary taken from English-language reference books and websites. The conceptual groups and linguistic analysis are displayed via the mind map Coggle used for the e-dictionary frame formation. The proposed linguocultural component embedded in the edictionary is rare in other existing trilingual e-dictionaries since they focus primarily on lexicographic material and their visual representation. Overall, the trilingual e-dictionary created in mind-mapping software is an effective etool for high school learners to study biological terms with their linguocultural commentaries.

The article deals with the results of environmental regulation of doses introduced into a multicomponent carbon-containing preparation for the burning of heavy metals and the microbiological activity of the soil. The relevance of the research is based on, on the one hand, in global degradation, degasification and reduction of soil fertility. On the other hand, it is the worldwide accumulation of production and consumption waste. This study aimed to assess the effect of doses of the product from ash, slag, and carbon black on pH, heavy metal content, and microbiological activity of ordinary chernozem soil for cultivating spring wheat. The experiments were conducted in a walled-zone of Northern Kazakhstan. Soil pH was determined by a potentiometric method, the application of floe discovered the microbiological activity of the soil, the microflora was accounted for by sowing the soil suspension on solid nutrient media, and heavy metals were determined by stripping voltammetry. Bacteria utilizing organic nitrogen compounds; microorganisms consuming mineral nitrogen; oligonitrophils; bacteria mobilizing mineral phosphates; cellulose-destroying microorganisms; nitrification and mushrooms were studied. The studied preparation was observed to contribute to the neutralization of the soil, and the activation of microbiological processes. According to the evidence, it can be verified that the preparation of ash and carbon black ambiguously affects the number of microorganisms. An increase in the number of ammonifying bacteria, nitrifying agents and the coefficient of transformation of organic matter, as well as an increase in the availability of soil with easily hydrolyzed nitrogen, were noted. The content of heavy metals did not exceed the maximum permissible concentration. Thus, the use of a product based on ash, slag, and carbon black to fertilize black earth soils on spring wheat crops are environmentally safe.

So, an end of environmental impact impacted by these effluents, it is necessary or the development of new technologies of removal. An alternative to remedy this problem is found in the application of the adsorption technique through the use of sodium titanium nanomaterials. These factors do not have surface areas, spaces between and charge transfer rates of efficient interfaces, or what significantly increases the adsorbents. Thus, the present work aimed to synthesize sodium titanium nanomaterials and to investigate their use for the removal of dyes or gum from the aqueous medium. The materials were synthesized using the hydrothermal method, without the use of a structured guide, using titanium dioxide as the starting material in the alkaline medium (10M NaOH). These materials were studied, using their use in the removal of organic pollutants in aqueous medium, where it verified the formation of fibrillar morphology for all the materials used. Through the X-ray diffraction technique, it was confirmed the establishment of four crystallographic phases of lamellar titanates, predominantly, of disodium titanate, with monoclinic symmetry. In short, the results proved that there was a formation of titanate nanomaterials. Tests to remove methylene blue are promising for the adsorptive activity of the captured materials concerning the starting oxide, removing up to 81% of the dye in 30 min. Titanium nanomaterials are efficient to remedy aquatic ecosystems contaminated by this organic pollutant; in addition, the collected data become a reference for future studies.

The development of aerospace engineering and mechanical engineering directly depends on the development of new metal materials and advanced technologies. The problem of creating materials and their types of processing to increase the level of operational properties is relevant in connection with the complication and tightening of working conditions of modern technologies. One of the most important tasks of contemporary aircraft construction is to increase the operational properties of the surface layer. The purpose of the article is to elucidate the effect of high-current electron beams of microsecond duration on changes in the surface layers of the heat-resistant multicomponent ion-plasma coating Ni-Cr-Al-Y under various conditions. Using a complex of metallophysical research methods, the physicochemical and structural-phase states of the surface layer were studied before and after modification of the samples. These samples were coated with heat-resistant condensed ion-plasma coatings of three different compositions using nine high-current electron beams in 9 modes with different values of electron energy and number of pulses in the selected interval of electron energy. An analysis of the structural phase changes occurring during modification was carried out. Cylindrical samples of targets made of heat-resistant nickel alloy ZhS36 coated with ion-plasma condensed multicomponent coating SDP-2 + VSDP-16. These samples were used according to serial technology, both with subsequent modification using highcurrent electron beams and without modification. It was found that chromium in the initial state is unevenly distributed: chromium is present in the particles; the matrix is depleted in chromium. The research results can be useful for scientists to study the properties of heat-resistant multicomponent ion-plasma coatings Ni-Cr-Al-Y and the effect of high-current electron beams on it, as well as for the manufacture of more heat-resistant materials in aerospace engineering and mechanical engineering.

The purpose of the research is to improve the technology of producing cheese whey proteincarbohydrate concentrates, in terms of binding moisture with the main components. Objects of the research were natural cheese whey obtained in the production of Rossiyskii cheese and ultrafiltration cheese whey concentrates with protein dry matter percentage of 35 and 55%, produced with the use of MMS Swissflow UF industrial ultrafiltration unit with ceramic membranes. The chemical composition and Physico-chemical properties of raw materials and the finished product have been studied using standard methods. Three stages
of sample dehydration have been identified. They conform to moisture release with different bonds and energy. Stage I is the production area where unbound moisture is heated and removed, and water molecules are held by weak capillary forces. Stage II is the production area for immobilized moisture removal. Stage III is the production area for chemically bound water removal, which conforms to the residual moisture after drying the sample. An increase in the least mobile water and a change in the ratio between different types of moisturebinding have been observed with an increase in the protein mass fraction in the dry matter of the samples. It has been found that the Maillard reaction occurred in cheese whey concentrates with protein dry matter percentage of 35 and 55% at the temperatures above 78 and 70 °C, respectively. The temperature range of the unbound moisture release was increasing during the drying process due to an increase of the protein content in concentrates as well as the rate of interaction between proteins and lactose leading to non-enzymatic browning of dry products. It has been established that drying cheese whey protein-carbohydrate concentrates with protein dry matter percentage of 35, and 55% is inexpedient at temperatures exciding 130 and 173 °C, respectively.

The aim of this study was designed to examine the efficiency of various iodine compounds in pigs’ diets. The impact of inorganic and organic iodine compounds – potassium iodate and iodated milk protein, which is a part of the "ProstTM" feed additive ("Innbiotech", Russia) – on the growth, meat productivity and lean meat yield of fattening pigs was studied. The physico-chemical composition and biological value of the meat were studied. The accumulation of iodine in animal muscle tissue was assessed. It was found that iodized milk protein contributed to more intensive growth than the inorganic iodine source. Specifically, animals fed the organic form of iodine were superior in terms of carcass weight and yield value of muscle and fat tissue. Compared to the control group, the experimental groups of pigs demonstrated a muscle tissue yield of 0.45%. Organic sources of iodine were also found to have a positive impact on the chemical composition of meat; animals fed the organic form of iodine surpassed those receiving inorganic iodine in terms of their meat’s dry substance, protein content and fat content. The level of iodine in the muscle tissue of pigs receiving organic iodine was considerably higher, and these pigs surpassed those receiving the inorganic iodine source in terms of the presence of essential amino acids in their muscle tissue.

Modification of chitosan with biocompatible synthetic polymers is important for the development of biodegradable medical materials with a tailor-made complex of properties. The issue of the influence of a polysaccharide macromolecule conformation on the synthesis and properties of the hybrid products remains acute. Conformational transitions of chitosan and their influence on the process of grafted polymerization of 2-hydroxyethyl methacrylate and N-vinylpyrrolidone onto the polymer and the properties of their copolymers were studied. To interpret the peculiarities of chitosan solutions properties, their viscosity was identified by the method of rotational viscometry; conformational transitions of the polymer polysaccharides were investigated by the method of spectrophotometry; dimensional characteristics of the polymer particles were assessed by the method of dynamic light scattering. Copolymers were characterized by the methods of IR-spectroscopy and gelpenetrating chromatography. Helix-coil conformational transition of the chitosan macromolecule was pH and temperature-sensitive. The effective size of the chitosan macromolecules for helix conformation was 14-35% larger than for the coil conformation. The grafted copolymer yield (98%) was significantly higher in the solutions of chitosan, where its macromolecules were in the coil conformation. The obtained results allow the researchers to create optimal conditions during the development of the copolymer-based biomedical materials with improved characteristics.

The enrichment of the molecular structure of silk fibroin by selenium atom led to an increase in the branching of fibroin macromolecule. As a result, the amorphous fraction of fibroin microfiber increases which leads to an increase in the strength characteristic of the silk thread. At the same time, this change in the supramolecular structure of fibroin involving a selenium atom has enabled us to study the two-modification mechanism for crystallizing fibroin microfibers. Based on studies on the use of temperature-gravimetric and X-ray diffraction (XRD) analysis and relative changes in the proportion of amorphous and crystalline regions, we came to the conclusion that fibroin microfibrils consist mainly of extended crystallites CSC – crystallites with the stretched chains. They alternate along the axis of microfiber with amorphous layers, the sizes of which are smaller than the sizes of the folded crystallites (CFC). Therefore, CFC cannot be located in amorphous layers between the CSC along the microfiber’s axis. As a result, the ability to fold branched sections of the macromolecule decreases, that is, CFC decreases. This increases the proportion of amorphous areas of microfibers of the fibroin. In the model, which is proposed by author non-crystallized in the form of CSC, segments of a macromolecule, on the sides of the central core and attached to it, restored their crystal structure (CFC) – with folded conformation of chains.
