Authors: Liu Junyao , Xie Wenping , Yang Jingsong , Yao Rongjiang , Wang Xiangping , Li Wenxiu
Published: September 2023

Saline soil from the coast is a valuable and readily available resource. It is also a valuable resource for reserving arable land. Adding organic fertilizers to salinized soils is an effective method of enhancement. However, saline soils cannot be improved using a single measure, and the effects of compound measures of organic fertilizers combined with mineral elements, such as humic acid, are significant and worthy of further examination. To explore the effects of various measures on the features of pH, electrical conductivity (EC), and nutrient changes in coastal salinized soils in Yancheng, Jiangsu Province, a ryegrass–alfalfa rotation with organic fertilizer and compound measures was designed. The findings indicated that the total nitrogen (TN) content of the soil increased and that all organic fertilizer composites decreased the electrical conductivity of the surface soil. However, the organic fertilizer with microbial fertilizer and humic acid was especially effective at regulating the pH and electrical conductivity of the surface soil when salts were prone to accumulation. In conclusion, our findings highlight new approaches to lowering salinity and boosting fertility in coastal saline soils: organic fertilizer with microbial fertilizers and humic acid, as well as organic fertilizer with attapulgite clay.

Published: September 2023

The objective of our investigation was to study the various effects of correct and incorrect application of fuzziness exponent, initial parameterization and fuzzy classification algorithms modeling on homogeneous management zones (MZs) delineation of a Coriandrum sativum L. field by using precision agriculture, soil chemical, granular and hydraulic analyses, fuzzy k-means zoning algorithms with statistical measures like the introduced Percentage of Management Zones Spatial Agreement (PoMZSA) (%), factor and principal components analysis (PCA) and geostatistical nutrients GIS mapping. Results of the exploratory fuzzy analysis showed how different fuzziness exponents applied to different soil parameter groups can reveal better insights for determining whether a fuzzy classification is a correct or incorrect application for delineating fuzzy MZs. In all cases, the best results were achieved by using the optimal fuzziness exponent with the full number of parameters of each soil chemical, granular and hydraulic parameter group or the maximum extracted PCAs. In each case study where the factor analysis and PCA showed optimal MZs > 2, the results of the fuzzy PoMZSA clustering metric revealed low, medium and medium to high spatial agreement, which presented a statistically significant difference between the soil parameter datasets when an arbitrary or commonly used fuzziness exponent was used (e.g., φ = 1.30 or φ = 1.50). Soil sampling and laboratory analysis are tools of major significance for performing exploratory fuzzy analysis, and in addition, the FkM Xie and Benny’s index and the introduced fuzzy PoMZSA clustering metric are valuable tools for correctly delineating management zones.

MASTERPIECES OF NATIONAL CULTURAL HERITAGE IN A COURSE OF LECTURES ON THE HISTORY OF UKRAINIAN CULTURE: THE PERESOPNYTSIA GOSPEL
Authors:   Mariupol State University, Nikolchenko Ju. Nikolchenko
Published: September 2023

The main objective of this article is to study the problem of presenting a unique cultural monument of Ukraine - the Peresopnytsia Gospel of 1556 - in a course of lectures on the history of Ukrainian culture for students majoring in Cultural Studies at Mariupol State University. The author focuses on those components of the history of the creation, use, and preservation of this unique monument of national cultural heritage that found their place in the course of lectures, which should form a sense of respect and reverence for national relics in future students majoring in cultural studies. The appearance of the Peresopnytsia Gospel coincides with the development of Renaissance culture on the Ukrainian territory, but with special national characteristics. Thanks to this, the teachers of the department have a great opportunity to comprehensively illustrate to students a certain era in the history of Ukrainian culture on its example, in particular, the development of theological thought and literature, book business, art, book miniatures. After the declaration of Ukraine's independence, the Peresopnytsia Gospel rightfully acquired the status of a national-state and political symbol - during the inauguration, the presidents of Ukraine swear on the manuscript, promising to be faithful not only to the Ukrainian people, but also to God. This issue is of particular importance in the dramatic present of Russia's military aggression against Ukraine, when, on the example of the Peresopnytsia Gospel, national cultural heritage is an important factor in the patriotic education of student youth. Key words: Peresopnytsia Gospel, history of Ukrainian culture, course of lectures, national cultural heritage, patriotic education.

The paper considers a new approach to the search for information parameters of the radar field, the source of which is a radar with a real antenna aperture. Such aperture is necessary for the construction of a digital radar map of the terrain, applicable for the navigation of an aircraft along a trajectory that is close to being vertical to the Earth's surface. The article reveals the essence of the approach. Because of the development of analog-to-digital conversion of the gi-gahertz frequency range, it became possible to analyze the radar signal reflected from the un-derlying surface of the Earth and located on it objects in details. It has opened up new opportu-nities in the search for information parameters of the reflected signal (a video pulse). There have been obtained some new information parameters, such as intensity of the reflected signal from the object, duration of the leading and trailing edges of the video pulse reflected from the underlying surface of the Earth and located on it objects, distance from the aircraft to the under-lying surface of the Earth. It is proposed to construct a relief map of a section of the underlying surface of the Earth and located on it objects in terms of a horizontal trajectory or a trajectory close to it. The paper analyzes a method for constructing a radar contrast map based on the in-tensity of the signals reflected from the underlying surface of the Earth and located on it ob-jects. There have been proposed such information parameters as the height of an object and an estimate of the height of the slope of the underlying surface of the Earth which are independent of external conditions and which can be considered as the main elements for building a digital three-dimensional map of the area. The obtained results can be considered as a source material for theoretical and practical research in the sphere of development of an all-weather high-precision navigation radar system.

The issue of product safety is acute in many countries and companies. Indeed, every year a large number of people catch various diseases after using products contaminated with harmful sub-stances. To increase food safety, there should be implemented some technologies which would enable quick testing of products and, using the obtained knowledge, to prevent appearance of harmful substances. Biosensor technologies which are utilized for conducting quick tests for agricultural purposes are being nowadays actively developed in the world. The use of data min-ing technologies can provide the identification of new knowledge about the nature and depend-ence of various harmful substances on external factors. The article considers the issues of con-struction and testing of forecasting technology, including analysis of existing solutions, search for forecasting models, usage of Data Mining methods to find qualitatively new knowledge and hypotheses, and hypothesis testing as well. The first section of the article provides an overview of existing models and methods, formulas for calculating the risk of aflatoxin. The second sec-tion contains a brief description of the data collection system which consists of a data ware-house, sensors and a mobile application as a data source. The results of data mining obtained after the use of Data Mining methods are presented in the third section of the paper. As a result, there was obtained a hypothesis of the effect on the appearance of mycotoxins in crops. Confir-mation or refutation of the hypothesis was performed by testing it using OLAP-technologies. The results of the hypothesis test are presented in the last section. The main result of the work was obtaining a data analysis system ready for testing in real conditions. However, it should be noted that there is a need for more extensive testing on large amounts of data which can be ac-cumulated over several years of observations.

Published: September 2023

The paper addresses the most important problems and tasks related to the objective need to cre-ate a single service delivery system for the railway industry of Ukraine which will provide high quality, safe and reliable service for the existing types of freight and passenger traffic. There have been considered three main classes of problems connected with rail transportation: maintenance of these processes by reliable and dependable service provided through the use of technical means; functioning of the service delivery system with the help of specialized soft-ware and hardware; monitoring and adjusting the processes of providing services during their implementation. Effective use of the means of the Ukrainian railway transport network (RTN) requires an analysis of the possible risks of RT during the transportation and the use of the cor-responding means to reduce the impact of risks in the transportation processes. The quality of transportation management can be significantly improved through the synthesis of these tools into a single system. It is necessary because in most cases of emergencies during transportation, such a system will collect and process statistics of emergencies to create a classification of the most dangerous ones in the form of a separate statistics. It, in its turn, will allow to objectively and promptly analyze both the causes of certain types of emergencies and accidents during transportation, and significantly reduce not only the risks of their occurrence, but also the po-tential damage from them. The article also offers a concept of system creation which allows to create a reliable, high quality, system-organized and practically safe system of RT services. Such a system will be a little bit dependent on the impact of most external and internal hazards and risks what is necessary to improve the quality of the provided services. For these problems there have been formulated and presented some specific examples of their solution that can be used for the provision of European quality services.
Spatial grasp model for dynamic distributed systems
Authors:   Institute of Mathematical Machines and Systems Problems of the National Academy of Sciences of Ukraine, Sapaty P.S.
Published: September 2023

More complex distributed and intelligent systems which relate to economy, ecology, communi-cations, security and defense, and cover both terrestrial and celestial environments are being developed. Their efficient management, especially in dynamic and unpredictable situations, needs serious investigations and development in scientific and technological areas. Their tradi-tional representations as parts operating by certain algorithms and exchanging messages are be-coming inadequate as such systems need much stronger integration to operate as holistic organ-isms pursuing global and often varying goals. This paper is focused on a completely different paradigm for organization and management of large dynamic and distributed systems. This par-adigm extends and transforms the notion of an algorithm for the description of knowledge pro-cessing logic. Moreover, it allows it to exist, propagate and operate as an integral whole in any distributed spaces which may constantly change their volumes and structures. Taking into con-sideration some organizational features related to dangerous viruses, as well as recent pandem-ics, this ubiquitous Spatial Grasp (SG) model is presented in the paper at philosophical and im-plementation levels, together with the introduction of special spatial charts for its exhibition and studies, which extend traditional algorithmic flowcharts towards working directly in dis-tributed spaces. Utilization of this model for the creation of resultant Spatial Grasp Technology and its basic Spatial Grasp Language, already described in details in numerous publications, is briefed as well. Elementary examples of dealing with distributed networks, collective human-robotic behavior, removal of space debris by a constellation of cleaning satellites and simulat-ing the spread of virus and vaccination against it explain SG advantages over traditional system organizations.

In conditions of constant displays of aggression in various fields of activity, which is one of the most acute problems of our time, corresponding preventive measures are becoming increasingly important. In its turn, it requires the improvement of the methodological support for decision-making to ensure security and counter various kinds of attacks. At the present stage, the remaining slowness of identification of incidents and determining the scale of their devel-opment is a characteristic feature of security management. Methodological complexity of the procedures for assessing security risks and corresponding calculations is stipulated by the lack of appropriate methods, software and technologies on the market, which complicates the devel-opment of automated decision support tools. This paper offers a universal method based on a formalized model of the relationship between objects (resources), aimed at them threats and expected risks. This model is based on the �threat � object� binary scheme expressed in a bipar-tite graph and provides for the division of the graph into subgraphs. There is built another (third) set that corresponds to the safety model with full overlap and protection mechanisms as well. Simultaneous utilization of the elements of ontological descriptions increases the level of the method concreteness and a clearer understanding of the environment state. A matrix ap-proach, which is closely related to graph models, is proposed for computations. The article pro-vides some schemes of technological implementation of the obtained solutions based on office applications and designing a corresponding information and analytical system. The proposed method can be applied in automated systems in many fields of activity.

Published: September 2023

The purpose of the research is to analyze the factors that influence the continuance intention to use Mobile-Assisted Language Learning (MALL) applications in the context of language courses in Indonesia. The study aims to understand the key factors that contribute to users' intention to continue using MALL applications, particularly in the context of the COVID-19 pandemic and the shift towards online and remote language learning. The research used the expectation-confirmation model and self-determination theory. Moreover, the research utilized a mixed-methods approach to achieve its objectives. A quantitative approach was employed, involving a survey with 445 respondents who had experience using MALL applications. The survey data was then analyzed using covariance-based structural equation modeling. Additionally, qualitative research was conducted through interviews with 17 respondents to gain a deeper understanding of rejected hypotheses and gather qualitative insights. The most important results of the research include identifying the factors that influence the continuance intention to use MALL applications. The study found that users' perceived usefulness of the application, their satisfaction with its usage, and their self-regulation ability significantly influence their intention to continue using MALL. These findings highlight the importance of these factors in shaping users' decision to persist with MALL applications for language learning. By understanding the factors that influence users' intention to continue using MALL, educational institutions and application providers can improve their offerings and tailor them to meet the needs and expectations of learners. This research advances the e-learning area by shedding light on the factors that influence the continuance intention to use MALL applications. By uncovering the importance of perceived usefulness, satisfaction, and self-regulation ability, the study contributes to the understanding of user behavior and decision-making in the context of e-learning. The findings can inform the design and implementation of MALL applications, leading to more engaging and effective language learning experiences in online and remote settings.

Published: September 2023

The COVID-19 pandemic put academic institutions around the world in the difficult position of suddenly having to organize many lectures and examinations over online channels only, due to students’ physical access to their campus buildings being restricted. While the search for possible solutions to this problem was often challenging, this situation also offered the unique opportunity to establish remote examination options, that might hold the potential to be continued even after the pandemic has hopefully ended. This report looks at how the Munich University of Applied Sciences (MUAS), one of the biggest universities of applied sciences in Germany, established its own solution for remote examination over the Internet. This report provides an overview of how MUAS developed its on-site competence- and application-oriented digital examination tool to work remotely during the pandemic, its general framework and experiences that were made during its inception. Included are descriptions of the technical setting of the solution, as well as some challenges that were had when implementing it and how those were resolved. As part of this research it was concluded, that support and administrative work for this kind of remote examination was much more intensive than for on-site digital examinations, but also lessened each subsequent semester. A well-organized support system makes it possible to offer remote digital examinations with good conditions regarding, for example, student equal opportunities and secure examination environments, although even now perfect conditions cannot be guaranteed. While not without its own deficiencies, MUAS new established system was lauded by many Bavarian educational facilities and is in the process of being deployed to other Bavarian universities. This paper serves to highlight a qualitative example of how e-learning approaches can be of use in the context of higher education examinations and hopefully provide ideas for others trying to establish their own similar solutions.
Motivationally Appealing Computer Science e-Learning Games: An Inclusive Design Approach
Authors: Osunde Osemwegie Joseph , Bacon Liz , Mackinnon Lachlan
Published: September 2023

Research has shown that e-learning games do not have the same level of appeal to girls, as they do to boys; particularly in the crucial 11-14 age group. In the United Kingdom, this is typically when they start to make subject choices that impact their future studies and careers. Given the shortage of females who choose computer science as a career, this study explores how e-learning games can be designed to be motivationally appealing to young learners. It further explores the role of game representations and its appeal to this age group. This empirical study addresses the research question: “Can we develop e-learning games which appeal and motivate girls of age 11-14 to study computer science concepts?” Two e-learning games were developed: one included game representations such as game colour, graphics, character, age appropriateness, storyline, number of players, violence, identified as appealing to young females and the other game included antithetical or neutral representations. The two developed prototypes were used to explore key e-learning game representations as used to teach computer science concepts. A total of 304 participants, comprising of 152 girls and 152 boys from a combination of same sex and mixed secondary schools in Southeast England, engaged with both experimental games. The experiment also elicited information on how learners interact with these games and the resulting game appeal, motivation and learning. The insight gained from the analysis of data captured during the experiments, provide the evidence to demonstrate that inclusive e-learning games which motivate and appeal to girls of age 11-14 can be developed. This can have a positive influence on their willingness to use such games to learn computer science concepts. This implies that the study found positive outcomes related to e-learning game appeal, motivation and the learning of girls of this age group. A follow-up longitudinal study could investigate the impact of significant e-learning game representations that appeal to the target group. This could provide additional evidence on the changes in the appeal of the investigated significant game representations over time, due to the influence of other factors such as socio-economic and socio-cultural differences. This understanding can further enhance inclusive e-learning strategies to improve diversity in computer science education and consequently the career pipeline.

Authors: Кушнір Микола Ярославович , Токарєва Катерина Анатоліївна
Published: September 2023

Основна мета публікації — розробка узагальненої LSTM-нейронної мережі з урахуванням передісторії скінченної глибини. Більшість робіт з даного напрямку присвячено багатопотоковим узагальненням з наявністю кореляції між потоками, тобто розглядається розширення LSTM-моделі в ширину аналогічно до панельних даних у часових рядах. Проводиться розширення моделі в глибину, що дозволить враховувати періодичні компоненти часових рядів та інші детерміновані складові процесу, тобто без передобробки даних. Як показано в прикладі, розробка даної моделі дозволяє розширити використання класичних LSTM-мереж на динамічні системи з чітко вираженою періодичною складовою. Крім самої розширеної моделі, розглядається проблема обчислення параметрів моделі, яке ґрунтується на методі зворотного поширення. Для цього обчислено частинні похідні результуючого вихідного сигналу за невідомими параметрами та показано рекурентність даних похідних за часом аналогічно класичній LSTM-моделі. Додатковою проблемою при створенні розширеної моделі є оцінка гіперпараметра ρ, який вказує на глибину передісторії процесу. В звʼязку з цим розроблено алгоритм оцінки гіперпараметра з подальшою оцінкою всіх параметрів моделі.
Метод виявлення складних для розпізнавання зразків у наборах даних для задач класифікації у машинному навчанні
Authors: Охріменко Антон Олександрович , Куссуль Наталія Миколаївна
Published: September 2023

Розглядається проблема неоднозначності в задачах класифікації в області машинного навчання. Задача класифікації полягає у навчанні моделі відрізняти екземпляри даних, що належать різним класам. Однак можливі ситуації, коли правильна класифікація певної множини екземплярів даних складна або навіть неможлива, незалежно від складності моделі машинного навчання. Запропоновано метод та алгоритм виявлення таких неоднозначних екземплярів даних, що базуються на використанні методу найближчого сусіда та аналізу класів екземплярів даних, розташованих поряд у просторі ознак, та дозволяють виділити підмножину неоднозначних екземплярів даних, що можуть негативно впливати на процес навчання моделі класифікації. З метою демонстрації практичного застосування алгоритму проведено експеримент на чотириканальному супутниковому композиті, що використовується для попіксельної класифікації сільськогосподарських культур. Визначено відсоток ненадійних даних загалом та окремо для кожної культури. Одним з основних результатів дослідження є можливість використання запропонованого алгоритму під час конструювання датасету (набору даних, dataset) для навчання моделі класифікації. Він допомагає виявити потенційно проблемні екземпляри даних та забезпечити якість вхідного набору даних. Крім того, розглянуто можливості застосування алгоритму після процесу навчання моделі при використанні в операційному режимі. Виявлення неоднозначних екземплярів може допомогти знайти потенційні помилки класифікації та покращити результати роботи моделі. Представлений алгоритм може стати важливим інструментом для дослідника впродовж повного циклу розробки моделі машинного навчання, починаючи від підготовки даних для навчання і закінчуючи її практичним впровадженням. Його застосування скорочуватиме час на отримання якісних навчальних даних, покращуватиме метрики класифікації та забезпечуватиме більш надійні результати у задачах машинного навчання.
Optimal allocation of a limited resource
Authors: Voronin Albert , Savchenko Alina
Published: September 2023

In various subject areas, the problem arises of such a distribution of a limited resource between the elements (objects) of the system, in which the system as a whole functions in the best possible way. Often this task is solved subjectively, based on the experience and professional qualifications of the decision maker (DM). In simple cases, this approach may be justified. However, with a large number of objects and in critical cases, the price of an error in a management decision increases sharply. It becomes necessary to develop formalized decision support methods for the competent distribution of resources between objects, taking into account all given circumstances. Many of such circumstances are usually limited resources. The most common case is that the total (global) resource of the system, which is to be distributed among individual objects, is limited from above. In practical cases, restrictions are imposed not only on the global resource, but also on the partial resources allocated to individual objects. In this case, restrictions can be imposed both from below and from above. Such restrictions are either known in advance or determined by technical and economic calculations or expert assessment methods. It is necessary to distinguish between conditional restrictions (when violation of the limits is undesirable) and unconditional restrictions (when their violation is physically impossible). It is easy to see that the sum of the lower constraints for all partial resources is the lower constraint for the global resource, and the sum of the upper constraints limits the global resource from above. Considering the given set of restrictions, it is required to distribute the global resource of the system between objects in such a way that the most efficient operation of the entire system as a whole is ensured. The problem lies in the construction of an adequate objective function to optimize the process of resources allocation in conditions of their limitation. A simple uniform distribution in this case is not suitable, as it can put some objects on the verge of impossibility of their functioning, while other objects will receive an unreasonably large resource.

In this study, the analysis of the understanding of space under the influence of light was made. The content of the study touched on the effect of light and space on human perception, both architecturally and computationally. The identity that the light adds to the space, the interaction of the material with the light, and the illusory properties of the light are explained. While examining these abstract concepts, the illumination area of the light was calculated with a computational application. The fact that light is one of the most effective elements used in space has revealed the necessity of designing form, material, and lighting together. It is understood that the effect of basic elements that make up space, such as form and material color, can be increased with angular lighting. It has been understood that if a textured surface is illuminated with a directional light, the visual effect of the surface will increase. However, it has been understood that a material with a smooth structure and a material with a rough structure cannot be illuminated with the same lighting method, and this visual effect will create negativity. For original lighting designs, it is necessary to make accented or homogeneous lighting according to the need, and it is possible to provide this with designed-planned lighting.

The world's strong economic growth and increasing populations have generated a remarkably growing demand for resources, especially energy. Current conventional sources cannot meet the future needs. Efforts are being focused on renewable energies, deep-sea oil and the development of new techniques to value heavy oils, tar sands and oil shale. This could bridge the gap between energy demand and supply. Several countries with oil shale deposits have launched projects to examine the possibility of exploiting these deposits. Morocco is one of these countries, with significant oil shale deposits in the Middle Atlas (Timahdit), Tarfaya, Tangier and Grand Atlas regions (Fig. 1) [1].
Morocco has a reserve of around 53 billion barrels of oil shale, in addition to a rich capacity for shale gas and oil. The exploration works for these unconventional hydrocarbons, which began several years ago, has proved highly encouraging. The first research into the development of oil shale in Morocco began in Tangier, with the creation of the oil shale company of Tangier. The company built a pilot plant with a daily capacity of 80 tons of oil shale. The Timahdit and Tarfaya deposits were discovered in the 1960’s.

Представлен обзор научной литературы о социально-психологических особенностях работающих и неработающих пенсионеров с дополнением новых знаний о качестве их жизни. Описано и проанализировано шесть психографических профилей пенсионеров в зависимости от их деятельности после выхода на пенсию или отправных точек выбора нового жизненного пути, что позволяет сформировать тип личности. Данные сведения необходимы психологам и специалистам по социальной работе для консультаций лиц предпенсионного возраста и новоиспеченных пенсионеров по вопросам их жизни на пенсии, правильного построения трудовой деятельности или эффективного (творческого) времяпрепровождения, включая развитие карьеры в позднем возрасте, без ущерба для физического и психического здоровья. Проанализированы основные причины продолжения трудовой деятельности пожилых людей на пенсии, которые позволяют дополнить знания о мотивации пенсионеров к труду. Полученные данные также важно учитывать при разработке государственной политики по активному вовлечению пожилых людей к работе на пенсии. Психологически процесс выхода на пенсию по своей природе аналогичен эмоциональным фазам, сопровождающим переходные периоды жизни человека. В той или иной форме с ними сталкиваются практически все пенсионеры после того как перестают работать. Их способность сориентироваться в этом процессе в конечном итоге определит, как они проживут этот этап жизни. В статье проанализировано пять стадий выхода на пенсию.

The article provides a review of research literature on the social and psychological peculiarities of working and non-working pensioners with additional new data on their life quality. Six psychographic profi les of pensioners based on their post-retirement activities and motivations for new life path choices were described and examined, enabling identifi cation of the subjects’ personality types. These data are essential for psychologists and social workers consulting people approaching retirement age and recent retirees on their retirement lifestyle, ways to organize their working life and effective (creative) pastime, including career development later in life, without sacrifi cing their physical and mental health. The article looks at the main reasons behind continuing work after retirement thereby supplementing the existing knowledge on post-retirement work motivations. It is important to consider the data obtained when designing public policies on post-retirement work promotion. In its psychological aspect, the process of settling into retirement is similar to the emotional phases associated with the transitional periods of human life. After quitting work, almost all retirees face them in one form or another. Their ability to navigate the process is what will eventually determine how they will spend this stage of their lives. The article analyzes fi ve stages of retirement.

Показано, что пептид KE (Lys–Glu, вилон) обладает иммуномодулирующим, онкостатическим и геропротекторным свойствами. Цель работы — оценка влияния пептида KE на экспрессию генов и синтез белков SIRT1, PARP1, PARP2 при старении мезенхимальных стволовых клеток (MSC) человека. Пептид KE повышает экспрессию гена и синтез белка SIRT1 в «молодых» MSC, соответственно, в 6 и 8,2 раза. Пептид KE снижает экспрессию гена и синтез белка PARP1 при старении MSC, соответственно, в 2,1 и 5,3 раза, а также снижает экспрессию гена и синтез белка PARP2, соответственно, в 2,1 и 4,7 раза. По данным молекулярного моделирования, пептид KE может взаимодействовать с последовательностью GCGG двунитевой ДНК (днДНК) в классической В-форме и с последовательностью GGGC искривленной днДНК нуклеосомы. В промоторах генов SIRT1, PARP1, PARP2 человека обнаружены указанные последовательности днДНК. Таким образом, пептид KE регулирует экспрессию генов и синтез белков SIRT1, PARP1, PARP2 в MSC человека при репликативном старении, что лежит в осно ве биологической активности и геропротекторного эффекта этого пептида.

It was shown that KE peptide (Lys–Glu, vilon) has immunomodulatory, oncostatic and geroprotective effects. The aim of this work is to evaluate the effect of the KE peptide on gene expression and protein synthesis of SIRT1, PARP1, PARP2 during aging of human mesenchymal stem cells (MSC). The KE peptide increased gene expression and synthesis of the SIRT1 protein in «young» MSCs by 6 and 8,2 times, respectively. The KE peptide reduced gene expression and PARP1 protein synthesis during MSC aging by 2,1 and 5,3 times, respectively; and also reduced gene expression and PARP2 protein synthesis by 2,1 and 4,7 times, respectively. According to molecular modeling data, the KE peptide can interact with the GCGG sequence of double-stranded DNA (dsDNA) in the classical B-form and with the GGGC sequence of the curved dsDNA nucleosome. The indicated dsDNA sequences were found in the promoters of the human SIRT1, PARP1, PARP2 genes. Thus, the KE peptide regulates gene expression and synthesis of SIRT1, PARP1, PARP2 proteins in human mesenchymal stem cells during replicative ageing, which underlies the biological activity and geroprotective effect of this peptide.
