Abstract
The purpose of the study - to conduct an analysis of the disability of ATO/JFO participants in 2014-2021 with a detailed comparative analysis of data of 2021 and determination of the needs of the mentioned contingent in rehabilitation devices. Operational information was collected according to the statistic form of ATO/OOS participants examined at the medical and social expert commissions: developed by the authors statistical form "Report on the causes of disability, indications for medical, professional and social rehabilitation in ATO participants for _____ year", which was summarized and processed. Materials were collected from 2014 to 2021. More than a half of those recognized for the first time as disabled, 2,997 people in 2021 (86.0%), 2,624 people in 2020 (81.2%), 3,297 people in 2019 (79.3%), 2,848 people (75.5%) in 2018 and 1,859 people (65.0%) in 2017 - received the disability group not as a result of traumatic injuries, but for other unspecified reasons that did not have a traumatization factor. The main causes of disability were diseases of the circulatory system (47.9%), musculoskeletal system (13.4%), mental and behavioral disorders (7.2%), neoplasms (3.8%), diseases of the nervous system (3.3%), endocrine diseases, nutritional disorders, and metabolic disorders (3.2%), diseases of the digestive organs (2.0%), some infectious and parasitic diseases (1.6%), respiratory diseases (1.3%) and other reasons (0.7%). In 2021, less than ¼ (14.0%) of ATO/JFO participants were initially recognized as disabled due to various traumatic injuries, which is 25.5% less than in 2020. Among the patients with injuries of the musculoskeletal system, prevailed the victims with injuries of the lower extremities - 92 people, with injuries of the upper extremities - 44 people, polytraumas 38 people, combined injuries - 22 people. Traumatic lesions of the spinal cord led to the onset of disability in 7 persons, traumatic eye lesions in 12 persons. Medical rehabilitation services, including restorative treatment, reconstructive surgery, and orthotics, were the most needed among the examined ATO/JFO participants. More than half of the participants of ATO/JFO received the disability group due to other reasons that did not have a trauma factor, not traumatic injuries. Traumatic brain lesions accounted for 6.9% of the total number of ATO/JFO participants recognized as disabled, musculoskeletal injuries - 3.9%. 1.1% were recognized as disabled due to polytraumas, 0.2% due to combined injuries. Traumatic lesions of the spinal cord led to the onset of disability in 0.2%. With a traumatic eye injury, 0.3% were recognized as disabled. Complicated limb injuries with damage to peripheral nerves accounted for 0.1% and blood vessels - 0.1%. Medical rehabilitation services, including restorative treatment, reconstructive surgery, and orthotics, were the most needed among ATO/JFO participants examined. The increase in the number of ATO/JFO participants initially recognized as disabled due to reasons not related to traumatic lesions requires further careful analysis, determination of the reasons for such a situation and the development of effective measures for the prevention of disability and the return of lost functionality in the specified contingent, which will become the topic of further research.

Abstract
Vaccine adjuvants help to enhance the immunogenicity of weak antigens. The adjuvant effect of certain substances was noted long ago (the 40s of the last century), and since then a large number of adjuvants belonging to different groups of chemicals have been studied. This review presents research data on the nonspecific action of substances originated from marine organisms, their derivatives and complexes, united by the name 'adjuvants'. There are covered the mechanisms of their action, safety, as well as the practical use of adjuvants derived from marine hydrobionts in medical immunology and veterinary medicine to create modern vaccines that should be non-toxic and efficient. The present review is intended to briefly describe some important achievements in the use of marine resources to solve this important problem.

Abstract
The low permeability of porin channels is the possible reason for Gram-negative bacterial resistance to antibiotics. The adaptive accumulation of lysophosphatidylethanolamine (LPE) in Yersinia pseudotuberculosis induces conformational changes of OmpF porin that may hinder the transport of antibiotics through this channel. The present study was aimed to test whether the changes in LPE content affect the resistance of bacteria to ampicillin. The addition of glucose to the culture medium was shown to simultaneously increase the level of LPE and minimum inhibitory concentration (MIC) for ampicillin of Y. pseudotuberculosis cells 6- and 2-fold, respectively. However, the coadministration of glucose and polyphenol extract from buckwheat husks reduced the content of LPE 2-fold and restored MIC to the control value. Thus, PBEH can be used as antibiotic adjuvant to improve an antibiotic's ability to cross the outer membrane. The present work demonstrated: (i) the role of adaptive changes in the lipid composition of Y. pseudotuberculosis in the development of antibiotic resistance, and (ii) the promising use of PBEH in combination therapy to increase the susceptibility of Gram-negative bacteria to the conventional β-lactam antibiotics, probably attenuating in vivo a previously demonstrated effect of LPE on the conformation and function of the OmpF channel.

Abstract
Increasing global temperatures are expected to increase the risk of extinction of various species due to acceleration in the pace of shifting climate zones. Nevertheless, there is no information on the physicochemical properties of membrane lipids that enable the adaptation of the algae to different climatic zones. The present work aimed to compare fatty acid composition and thermal transitions of membrane lipids from green macroalgae Ulva lactuca harvested in the Sea of Japan and the Adriatic Sea in summer. U. lactuca inhabiting the Adriatic Sea had bleached parts of thalli which were completely devoid of chloroplast glycolipids. The adaptation to a warmer climatic zone was also accompanied by a significant decrease in the ratio between unsaturated and saturated fatty acids (UFA/SFA) of membrane lipids, especially in bleached thalli. Hence, bleaching of algae is probably associated with the significant decrease of the UFA/SFA ratio in glycolipids. The decreasing ratio of n-3/n-6 polyunsaturated fatty acids (PUFAs) was observed in extra-plastidial lipids and only in the major glycolipid, non-lamellar monogalactosyldiacylglycerol. The opposite thermotropic behavior of non-lamellar and lamellar glycolipids can contribute to maintenance of the highly dynamic structure of thylakoid membranes of algae in response to the increasing temperatures of climatic zones.

Abstract
Domain III (DIII) of the tick-borne encephalitis virus (TBEV) protein E contains epitopes, which induce antibodies capable of neutralizing the virus. To enhance the immunogenicity of this protein, which has a low molecular weight, the aim of the present work was to express, isolate, and characterize a chimeric protein based on the fusion of the bacterial chaperone HSP70 of Yersinia pseudotuberculosis and EIII (DIII + stem) as a prospective antigen for an adjuvanted delivery system, the tubular immunostimulating complex (TI-complex). The chimeric construction was obtained using pET-40b(+) vector by ligating the respective genes. The resulting plasmid was transformed into DE3 cells for the heterologous expression of the chimeric protein, which was purified by immobilized metal affinity chromatography (IMAC). ELISA, differential scanning calorimetry, intrinsic fluorescence, and computational analysis were applied for the characterization of the immunogenicity and conformation of the chimeric protein. Mice immunization showed that the chimeric protein induced twice the number of anti-EIII antibodies in comparison with EIII alone. In turn, the incorporation of the HSP70/EIII chimeric protein in the TI-complex resulted in a twofold increase in its immunogenicity. The formation of this vaccine construction was accompanied by significant conformational changes in the chimeric protein. Using HSP70 in the content of the chimeric protein represents an efficient means for presenting the main antigenic domain of the TBEV envelope protein to the immune system, whereas the incorporation of this chimeric protein into the TI-complex further contributes to the development of a stronger immune response against the TBEV infection.

Abstract
The HA1 subunit of the influenza virus hemagglutinin (HA) is a valuable antigen for the development of vaccines against flu due to the availability of most antigenic sites which are conformational. Therefore, a novel adjuvanted antigen delivery system, tubular immunostimulating complexes (TI-complexes) comprising monogalactosyldiacylglycerol (MGDG) from different marine macrophytes as a lipid matrix for an antigen, was applied to enhance the immunogenicity of recombinant HA1 of influenza A H1N1 and to study the relation between its immunogenicity and conformation. The content of anti-HA1 antibodies and cytokines was estimated by ELISA after the immunization of mice with HA1 alone, and HA1 was incorporated in TI-complexes based on different MGDGs isolated from green algae Ulva lactuca, brown algae Sargassum pallidum, and seagrass Zostera marina. Conformational changes of HA1 were estimated by differential scanning calorimetry and intrinsic fluorescence. It was shown that the adjuvant activity of TI-complexes depends on the microviscosity of MGDGs, which differently influence the conformation of HA1. The highest production of anti-HA1 antibodies (compared with the control) was induced by HA1 incorporated in a TI-complex based on MGDG from S. pallidum, which provided the relaxation of the spatial structure and, likely, the proper presentation of the antigen to immunocompetent cells.

Abstract
The tubular immunostimulating complex (TI-complex) consisting of cucumarioside A2-2, cholesterol and monogalactosyldiacylglycerol (MGDG) from marine macrophytes is the perspective antigen delivery system for subunit vaccines. MGDG is a lipid matrix for the protein antigen incorporated in the TI-complex. The aim of the present work was to study the influence of MGDGs from different macrophytes on conformation and immunogenicity of the secreted recombinant uncleaved hemagglutinin monomer (HA0S) of influenza A virus H1/N1. Differential scanning calorimetry, fluorescence spectroscopy and circular dichroism showed a dependence of the conformational changes of HA0S on the microviscosity of MGDG. The most viscous MGDG from Zostera marina induced the strongest rearrangements in protein conformation. Immunization of mice with HA0S within TI-complexes comprising different MGDGs resulted in an approximately 2-fold increase of the levels of anti-HA0S antibodies and granulocyte-macrophage colony-stimulating factor (GM-CSF) compared with those induced by HA0S alone. TI-complexes based on MGDG from Z. marina stimulated the maximal production of GM-CSF. However, humoral immune response (anti-HA0S antibodies), unlike cell-mediated immune response (GM-CSF), did not depend on the physicochemical properties of MGDGs. It is assumed that this is due to the different localization and conformational lipid sensitivity of the HA0S regions, which are responsible for these types of immune responses.

Abstract
Primary cell cultures obtained from somatic and larval tissues of bivalve molluscs and from embryos of sea urchins were frozen to -196 degrees C by two-step freezing using 10% dimethyl sulfoxide (DMSO) or/and trehalose (3-30 mg/ml) as cryoprotectants. We estimated both cell viability and the RNA synthetic activity after freeze-thaw. Total lipid extracts from the tissues of echinoderms examined as possible cryoprotective agents demonstrated a weak cryoprotective capacity. Mussel lipid extract was found to possess a considerable cryoprotective activity. Cryoprotective capacity of tested lipids correlated with their thermotropic behaviour. DMSO + trehalose combination was shown to be a favourable cryoprotectant and sea urchin blastula cells the most freezing-tolerant cells.
