Vancomycin in anterior cruciate ligament graft preparation; does it really reduce infection rate?
Authors: Osman Sari M. , Lawati Ali Abdullah Mohammed Al
Published: February 2025

Background: The aim of our study is to evaluate how the incidence of septic arthritis or postoperative infection is affected by the use of vancomycin in preparation of grafts during anterior cruciate ligament (ACL) reconstruction.
Methods: This is a retrospective comparative study conducted between two groups, first group operated in the period from August 2017 to August 2018, second group operated in the period from December 2022 to December 2023. It focuses on the incidence of post-operative infection rate in ACL reconstruction surgeries. All patients who had ACL reconstruction were included, all surgeries were performed by a single surgeon at the same hospital with the same set up and consumables. Infection was defined as a return to the operating room for irrigation and debridement within 90 days after surgery.
Results: Total of 130 patients were included in the study, first group (vancomycin group) or second group (non-vancomycin group) no patients suffered from postoperative deep infection, neither on the immediate post operative follow up, nor at the end of their final follow up. Comparing the two groups, more revision anterior cruciate reconstructions included in the second group, yet no single case of infection took place in any of the two groups.
Conclusions: In conclusion we found no difference between adding vancomycin to the graft or not adding it, as both groups showed no infection.

Authors: Roby Ashwin , M. Nasneem , Mathew Arun Mammen
Published: February 2025

Background: Supracondylar Intercondylar fractures frequently exhibit greater complexity than supracondylar fractures and may result in considerable complications if not appropriately managed. The present study assessed the benefit of open reduction internal fixation (ORIF) of supracondylar-inter-condylar fracture femur using distal femoral locking plates in terms of functional outcome of the patient.
Methods: The present descriptive study conducted in a tertiary healthcare centre located in Kollam, Kerala. The study included patients suffering from supracondylar intercondylar fracture femur fixed by ORIF using distal femoral locking plates. The patients were treated and assessed using range of motion, Knee society score and time taken for weight bearing. These findings were then compared for association with demographic and clinical variables. The data was analysed using chi-square test and p<0.05 was considered as statistically significant.
Results: The study involved a total of 63 patients with supra-condylar intercondylar femur fractures, with most being females over 70 years old. Postoperatively, most patients showed a range of motion of 91-120 degrees, and the time for radiological union was less than 6 months. The mean KSS score improved significantly at 12 months, with the majority having excellent scores. The study also found significant differences in mean range of motion based on age, type of fracture, and open/closed fractures. The time taken for full weight bearing was also associated with the type of AO fractures.
Conclusions: The study reveals significant differences in weight-bearing outcomes after ORIF of supracondylar intercondylar femur fractures. C1 fractures showed positive recovery, while C2 and C3 required extended rehabilitation. The study emphasizes fracture classification and personalized treatment for improved patient outcomes.
Calcaneum tuberculosis-an uncommon phenomenon: narrative review
Authors: Kumar Sumit , Kumar Rajendra , Jayant Neeraj , Gautam Chandrakant , Aggarwal Vipul
Published: February 2025

The Mycobacterium tuberculosis is the cause of tuberculosis (TB), a dangerous and highly contagious infection that is a major source of morbidity and mortality. One to three percent of cases have osteoarticular TB, and 10% of these cases involve foot and ankle involvement. The bone in the foot most frequently attacked by TB is the calcaneus. There are currently relatively few case series studies and case Report available that describe this uncommon phenomenon. The aim of this narrative review is to find information on the calcaneum tuberculosis-An uncommon phenomenon. We evaluated the medical records of some patients with 4 to 68 years, who had isolated calcaneal tuberculous osteomyelitis. As part of the systematic search, the phrase "calcaneal tuberculosis-an uncommon phenomenon" was created in relation to integrative, along with its synonyms, and the search database was used. The Google search engine was used to manually search PubMed and Google Scholar. The database did not include any further articles. According to the study's conclusions, Mycobacterium tuberculosis is the main cause of TB, a dangerous and communicable infectious illness. Calcaneal tuberculosis is uncommon. A high degree of clinical suspicion, in addition to positive imaging data, GeneXpert findings, and Gram stains, can aid in the diagnosis of TB calcaneus because it is an uncommon illness. To stop the illness from spreading to other bones and joints, early identification is crucial. Patient was treated with antitubercular medication and had a successful operation to correct the abnormalities.
Issa Shivji’s “Silent Class Struggle” and Decolonization in Tanzania: Class Struggle or Class Struggle for Classes?
Authors: Borkunov Nikita
Published: February 2025

This article focuses on the history of the heated debate that erupted in the early 1970s as a result of the publication of the article “The Silent Class Struggle” by contemporary Tanzanian scholar Issa Shivji, written while he was still a student and first published in the activist journal Cheche. By reconstructing the event and intellectual context of the article's writing, the author proposes to interpret the article not only as a research text, but also as a political statement by an engaged scholar involved in the global political project of decolonization. By demonstrating connections between the political vocabulary of the Ujamaa era, class concepts emerging in Dar es Salaam's popular urban culture, and debates on the campus of the University of Dar es Salaam, the author shows the innovations in political language and imagination that the article's publication introduced to the public debates around Tanzania's global and national politics in the 1970s.
Griots are the Keepers of the Historical Memory of the Peoples of West Africa
Authors: Tatarovskaya Irina
Published: February 2025

The article is devoted to the role of Griots in the preservation and transmission of historical knowledge of the Manden peoples. In the absence of writing, the story in the mouth of the storytellers took the form of an epic legend, where historical truth is intertwined with fairy-tale and mythological motifs. The most beloved epic tale of the Griots is “Sundiata”. Due to the oral form of transmission of this work, there are many variants of the epic. Despite the differences in the transmission of historical realities, the oral versions of the legend have elements of historical truth. The article shows that the epic “Sundyata” is of scientific interest to historians. The analysis of several versions of the legend is given. Currently, the “Sundyata” remains a symbol of identification of the Manden peoples. Through the efforts of the Griots, this epic legend received a “new” life and took the form of an ideological story. Since independence, the new West African States have used the epic legacy of the Griots to build national identity and legitimize power. One of the processes was the decision to restore the code of laws of the Manden peoples, which were preserved in the oral presentation of the Griots and are presented in one of the last chapters of the epic “Sundyata”. The article examines the historical and cultural significance of the charter “Kurukan Fugue”. This unique historical document is one of the oldest constitutions in the world. The author concludes that the Griots are outstanding chroniclers of history. They managed to preserve the historical past of the Manden peoples in the form of epic legends, which are an excellent, and in some cases the only source on the medieval history of West Africa.
Nikolai Konstantinovich Mosolov is an Unwilling Historian of Namibia
Authors: Gribanova Valentina
Published: February 2025

The study of the history of Namibia in Russian historiography was not sufficiently complete. Meanwhile, a significant contribution to the description of the most important pages of the history of this country was made by our compatriot, Nikolai Konstantinovich Mossolow, who lived in southern Africa for most of his life. He was a man, on the one hand, unique, and on the other, typical of the fate of many Russians born at the beginning of the 20th century. He was a descendant of families that left a significant mark in the field of culture, military affairs and entrepreneurship in pre-revolutionary Russia. After the revolutionary events, he found himself abroad and received a classical historical education at the famous Humboldt University of Berlin. Then, following his family, Nikolai Mosolov leaves pre-war Germany for the pacific Southwest Africa. After learning the Herero language and working in the archive, he wrote and published several fundamental works on the history of Namibia. Thematically, his books dealt with the study of the history of mission stations: the first Herero Rhine Mission Station in Southwest Africa in Ojikango, the Otjozondjupa mission station, as well as the history of Fort Namutoni and the capital of the country — Windhoek. Knowing Russian, N. K. Mosolov saved many lives. Soviet vessels entered Walvis Bay only in exceptional cases after sanctions were imposed against South Africa in the early 1960s. Nikolai Konstantinovich acted as an interpreter during the treatment of sick and wounded Soviet sailors who ended up in the Windhoek hospital. These acquaintances often continued even after the recovered patients left for their homeland. Nikolai Mosolov devoted his life to studying the history of the country that became his second homeland. But he carefully preserved everything that connected him with Russia, and did not lose touch with the Russian language and culture.
Theodora Büttner is the Head of the Leipzig School of African Studies
Authors: Popova Kseniya
Published: February 2025

The article examines the biography and contribution to the development of East German African studies of Theodora Büttner. Her career in administrative positions at the Karl Marx University in Leipzig largely contributed to the development of Leipzig as one of the two leading centers for the study of Africa in the GDR. T. Büttner's research on the ancient and medieval history of Africa became a scientific contribution to historical African studies, the generalized result of which was accumulated in the first volume of “History of Africa”. The four-volume “History of Africa” edited by T. Büttner was the first general work in German, which examines the political, socio-economic and cultural development of the peoples of Africa throughout history. In the first volume, T. Büttner describes the history of African state formations in the pre-colonial and early colonial period and refutes the thesis that Africa “did not have its own history”. The article concludes about Theodora Büttner's great contribution to the study of Africa and the development of African studies as a science in the GDR and its misconceptions.
Onesimos Nasib and His Legacy in Learning the Oromo Language and Culture (Ethiopia)
Authors: Ivanova Lubov
Published: February 2025

The fate of Onesimos Nasib symbolizes the history of Oromo language studies, the difficulties associated with its spread, as well as political problems in Ethiopia. Being Oromo by birth, Onesimos made a great contribution to the formation of the education system for his people in their native language as well as created a written base of Oromo cultural heritage. O. Nasib managed to combine Christian theology with Oromo ideas about god (Waaqa), and interpret Oromo religious concepts for a better understanding of biblical texts, which he and a group of compatriots translated into the Oromo language. The biography of Onesimos Nasib and his activities became known thanks to the research of Oromo scholars reviving the historical heritage of the Oromo in Ethiopia.
Legal Aspects of the Evolution of Relations and the Main Motives for Rapprochement between the Russian Federation and the People’s Republic of China
Authors: Uzdenov Sh. Sh. , Ermakov D. N. , Zababurin A. V.
Published: February 2025

Aim. The authors interpret Russian-Chinese relations in terms of the crisis of the unipolar world and the result of the failure of the old concept of Russia’s foreign policy, which can be conventionally called “Atlanticism”.

Methodology. The article is intended to contribute to the study of the recent history of Russian-Chinese relations, from the point of view of methodology; in this regard, the authors pay much attention to the chronology of the development of relations between Russia and the PRC. At the same time, the authors have the task of showing to non-East historians the process of Russia’s turn towards strengthening relations with China.

Results. The authors help the teacher to form ideas about the trends in the development of modern Russian-Chinese relations within the framework of tracing the chronology of changes in these relations in the context of analysing the crisis of the unipolar world.

Research implications. The authors divide Russia’s past foreign policy into “Atlanticism” and “Eurasianism”, examining Russian-Chinese relations in the context of the latter, demonstrating that Central Asia and Kazakhstan are now part of the system of joint interests of Russia and China, so Russia’s geopolitical horizons are shifting towards the Pacific Ocean, i.e., far beyond the former USSR.

Published: February 2025

The effect of the electrode sizes, the cell design and the compression force of the electrode
modules on the impedance and discharge characteristics of lithium-sulfur cells was studied. It was shown that
Swagelok and pouch cells with identical electrodes have different electrochemical characteristics – charge transfer
resistance, discharge capacity and cycling duration. It was found that the discharge capacity at the first cycle
of Swagelok and pouch cells differs by 20% approximately. The capacity of pouch cells decreases faster during
cycling. The cycling of pouch cells in a compressed state (similar to Swagelok cells) does not improve the
electrochemical characteristics of pouch cells.

Published: February 2025

The article discusses the methodological aspects of urban area assessment based
on the integration of basin, vector, landscape-geochemical and ecological-functional models.
Tokmakovsky ravine, located on the southern outskirts of Saratov, was chosen as the object
of research. The valley of the ravine is a typical element of the landscape structure of the
Volga upland and has preserved traditional forms of nature management. The structural and
functional analysis of the model valley complex shows the possibility of using the properties of an erosion network for collecting and cleaning surface runoff. A spatial scheme for the placement of biological compensators based on the
existing cascade of ponds has been developed. A town planning solution has also been proposed for the organization of recreational areas in
the upper reaches of the catchment area, areas of multi-storey buildings and at the confluence of the Tokmakovsky Creek into the Volgograd
reservoir.
Genus Polyptycha Defretin-Lefranc, 1960 (Porifera, Hexactinellida)
Authors:   Saratov State University, Pervushov Evgeny M.
Published: February 2025

The Polyptycha sponges have been registered for the first time in the Upper Cretaceous beds from the Volga Region. The skeletons
of those true colonies are peculiar for bushy morphotype complicated by anastomoses of the parent modules at their bending. The systematic
position of the genus is disputable. This results from the incomplete understanding of the diverse skeleton morphologies in the Late Cretaceous
hexactinellids and, correspondingly, from the lack of any standard criteria as regards the taxa of the “family” and the “genus” levels.
The Impact of Career Plateau and Organizational Support on Work Performance Through Organizational Justice and Employee Satisfaction At the Samsat Offices of Pidie and Pidie Jaya Regency
Authors: Herlina  , Adam Muhammad , Mukhlis
Published: February 2025

This study aims to examine the impact of career plateau and organizational support on work performance, with organizational justice and employee satisfaction serving as mediating variables, at the SAMSAT offices in the Pidie and Pidie Jaya districts. The research was conducted at the One-Stop Integrated Administration System (SAMSAT) offices in Pidie and Pidie Jaya. The population for this study consisted of all SAMSAT employees from both districts, totaling 113 individuals. The sampling technique employed was Total Sampling, where every member of the population had an equal chance of being selected as a sample. Data were collected using a Likert scale and analyzed using Partial Least Squares (PLS). Descriptive analysis revealed that career plateau, organizational support, organizational justice, employee satisfaction, and work performance at the SAMSAT offices in Pidie and Pidie Jaya were not functioning optimally. The results of direct testing showed that job satisfaction had a significant effect on work performance, while career plateau and organizational support did not directly influence work performance. Organizational justice was found to significantly affect job satisfaction, and organizational support contributed to enhancing perceptions of organizational justice. However, no direct effects of career plateau and organizational support on work performance were identified through the mediating pathways of organizational justice and job satisfaction. The practical implication of these findings is that organizations should prioritize improving employee job satisfaction through career development, enhanced compensation, and strengthening organizational support. Additionally, it is crucial to ensure clear career paths and development opportunities to mitigate feelings of stagnation (career plateau) among employees. By addressing these factors, organizations can enhance employee satisfaction and overall performance.

Published: February 2025

O projeto escola cidadã visa promover ações estratégicas de educação e saúde para o exercício da cidadania, por meio do fortalecimento de redes sociais comunitárias com a implementação de projetos formativos, informacionais e comunicacionais, mediados por tecnologias, a partir de metodologias participativas. Trabalha as questões de saúde multidisciplinarmente, reforçando os aspectos de informação, comunicação e educação em saúde, com a perspectiva de proporcionar mais autonomia e governança com ações de comunicação midiática focadas na saúde coletiva, considerando o entendimento de que saúde é um estado de bem-estar físico e mental e depende diretamente das condições de vida da população. Trata-se de uma metodologia qualitativa e participativa, focada em oficinas cocriativas de produção de conteúdos, que têm como objetivo promover a circulação de saberes, fortalecendo o engajamento comunitário junto ao público participante, proporcionando a tomada de decisão quanto às boas práticas em saúde e ainda o discernimento sobre a desinformação e suas consequências na prevenção de doenças e promoção da saúde por meio de ações de educação, informação e comunicação em saúde. Quatro oficinas foram realizadas nas comunidades de Ceilândia e Itapoã, no Distrito Federal, envolvendo 32 pessoas. Foi abordada a importância da imunização em mulheres e como identificar e prevenir a desinformação a partir da cocriação de materiais comunicativos socializados com os grupos de interesse dos participantes das oficinas. Observou-se que os processos formativos foram satisfatórios, pois, além de serem construídas nuvens de palavras temáticas a cerca dos temas abordados, também foram elaborados cards para veiculação em mídias sociais e grupos de WhatsApp, demonstrando o elevado grau de engajamento da comunidade aos desafios propostos. Entre os relatos, observou-se o estímulo ao diálogo crítico frente aos riscos proporcionados pela desinformação, em particular, no período mais severo da pandemia de Covid-19 e ainda na atualidade. Outrossim, percebeu-se que a população já deu início aos desdobramentos desejados ao protagonismo em rede, organizando e viabilizando novos grupos multiplicadores da temática e da metodologia introduzidos pelo projeto.
Idiolektostylem w mur, czyli o idiolekcie, idiostylu i krytycznej analizie dyskursu – na przykładzie felietonów Krzysztofa Skiby w tygodniku „Wprost”
Authors: Kudra Andrzej
Published: February 2025

The author ponders the issue of idiolect from a theoretical perspective, which cannot be done without taking a textual example into consideration. “Text filter” is central to idiolect studies. It is not possible to restrict studies only to language system research; it is necessary to address axiological issues and to treat the language in a holistic way. For that reason, in the case of an idiolect, it would be more adequate to talk about an idiostyle and, better still, about an idiolectostyle.

Fuel Properties of Briquettes Made from Acacia Mangium Pods and Plantain (Musa Paradisiaca) Peduncles with Cassava Starch Binder
Authors: Katamani Patrick , Antwi Kwaku , Mitchual Stephen Jobson
Published: February 2025

This study used cassava starch binder to produce and investigate briquettes made from plantain peduncles and Acacia mangium pods. It examined fuel properties and the effects of binder viscosities (8cP, 14cP, 29cP) and quantities (30g, 50g, 70g) on briquettes’ physico-mechanical properties. A. mangium pods exhibited superior fuel characteristics:  higher gross calorific value (17.68 ± 0.13 MJ/kg), lower ash content (3.60%), and higher volatile matter content (90.35%) compared to plantain peduncles’ 12.58±0.37MJkg, 31.60% and 63.67% respectively. Plantain peduncle briquettes exhibited higher relaxed density (504.09-565.17 kg/m³), superior compressive strength in the cleft (8.50-19.99 N/mm), and greater impact resistance index (166.66-500%) compared to A. mangium pod briquettes’ (1.82-4.40N/mm) and (125-166.66%) respectively. A. mangium pod briquettes were more prone to expansion, with length increases of 16.35-42.13% and diameter increases of 0.88-2.45%, compared to plantain peduncle briquettes’ length increases of 1.43-30% and diameter increases of 1.06-2.16%. Importantly, statistical analysis underscored the significant (p < 0.05) influence of binder properties on the physico-mechanical properties of the briquettes. The impact of binder properties was distinct for each biomass type, with more intricate relationships observed for A. mangium pod briquettes. Optimizing binder properties enhances briquette quality. Both biomass types have the potential for briquette production.Keywords: Plantain peduncles, Acacia mangium pods, binder viscosity, binder quantity and centipoise (cP)

Designing Complex Software Architecture : Guidelines on Pattern Selection and Microservice Identification Methods
Authors: Lauber Vincent Georg
Published: February 2025

Designing enterprise software systems requires careful selection of architectural styles and patterns that align with both technical and organizational requirements. This research proposes a selection framework that integrates these criteria, providing structured guidance for both pattern selection and the design process.
Effective architectural style selection necessitates a nuanced evaluation of organizational compatibility, rooted in a comprehensive understanding of relevant quality criteria. Assessing the organizational fit of design approaches within a selected architectural style ensures alignment with the organization’s specific preconditions and objectives. Throughout this process, quantifying the fulfillment of quality criteria establishes a consistent, quality-centered approach from initial selection to implementation.
This study examines the strategic considerations involved in adopting complex architectural patterns within software engineering, with a particular focus on the challenges of contemporary architecture design. It identifies critical decision-making factors and quality attributes that guide architectural choices, synthesizing these insights into a framework that inform architectural choices and support effective design decisions.

Published: February 2025

Direct ethanol fuel cells are considered indispensable and prospective energy storage devices due to their high volumetric energy density. Platinum (Pt) and Pt-based alloys are regarded as the most effective catalysts for both oxygen reduction reaction (ORR) and ethanol oxidation reaction. To further enhance the catalytic performance of the catalyst, it is necessary to improve the mass activity and utilization efficiency of Pt. In this work, we report a strategy for fabricating ordered mesostructured platinum-palladium alloy nanotubes (MPPNs) with high hierarchical porosity (68%) and abundant exposed active edge sites. MPPNs exhibit excellent catalytic activity and stability for ORR, with a mass activity approximately 7.4 times higher than that of the commercial Pt/C catalyst. After 20 k cycles of accelerated durability test for ORR, MPPNs demonstrate impressive retention of their original mass activity, maintaining a value of 93.9%. Furthermore, they display superior catalytic activity and stability for ethanol oxidation reactions, with a mass activity about 2.4 times higher than that of commercial Pt/C. After the 2,000 scan cycles, the mass activity remains at 84.5% of initial performance. Both experimental and theoretical studies reveal that the synergistic effect of neighboring (111) and (100) facets on the edge sites plays a critical role in enhancing the electrocatalytic selectivity, activity and stability.

The production of storable hydrogen fuel through water splitting, powered by renewable energy sources such as solar photovoltaics, wind turbines, and hydropower systems, represents a promising path toward achieving sustainable energy solutions. Transition-metal phosphides (TMPs) have excellent physicochemical properties, making them the most promising electrocatalysts for hydrogen evolution reaction (HER). Traditionally, achieving good crystallinity in these TMPs typically requires prolonged (≥ 2 h) high-temperature pyrolysis, which is time-consuming and generally yields samples with large particle sizes, adversely affecting the catalytic activities. Herein, for the first time, we present a groundbreaking discovery in the synthesis of grain-boundary-rich RuP2 nanoparticles within a very short time frame of nine seconds, using a fast Joule heating strategy (RuP2 JH). Subsequent electrochemical tests reveal that the as-synthesized RuP2 JH not only exhibits platinum-like HER activity, achieving overpotentials of 22 mV, 22 mV and 270 mV to reach a current density of 10 mA cm-2 in 0.5 M H2SO4, 1.0 M KOH, and 0.1 M phosphate buffered solutions, respectively, but also exhibits exceptional long-term stability. Moreover, it exhibits a Faradaic efficiency exceeding 96%. This work significantly contributes to the expanding repertoire of TMPs synthesized via Joule heating by showcasing exceptional performance toward HER and other energy-related catalytic applications.

Noble-metal single-atom catalysts (SACs) have arisen as a research hotspot in heterogeneous catalysis resulting from superior noble-metal-atom utilization, well-defined catalytic centers, and tunable microenvironments. Recently, the advent and rise of noble-metal SACs supported by layered double hydroxides (LDHs) have injected fresh vitality and vigor into this research field. LDHs offer distinct advantages as the support of SACs, such as an ordered and adjustable crystal structure, a two-dimensional layered structure possessing a large specific surface area, facile synthesis with cost-effectiveness, and strong co-catalytic metal-support interaction between LDHs and noble-metal single atoms. In this review, we classified and comprehensively outlined the current synthesis strategies of noble-metal SACs supported by LDHs, and conducted an in-depth analysis of the specific mechanisms underlying each strategy. Subsequently, considering the critical role of the microenvironment of SACs in affecting their catalytic-related properties, we discussed the current microenvironment regulation strategies of LDH-supported noble-metal SACs. We also provide an introduction to the characterization techniques for noble-metal singe-atom sites in LDH-supported noble-metal SACs. Furthermore, we outlined the diverse applications of LDH-supported noble-metal SACs in various catalytic fields and discussed the roles played by noble-metal atoms and LDHs in relevant catalytic processes. Finally, we delineated the challenges and future research directions for the development of LDH-supported noble-metal SACs.

Multilayer packaging, extensively used in the food, beverage, and cosmetics industries, offers excellent protection and durability by combining materials such as paper, plastic, and aluminum. However, its complex structure creates significant challenges in recycling, particularly in separating its layers. This review, conducted through a scoping analysis of peer-reviewed literature obtained from databases such as Google Scholar, PubMed, and ResearchGate, reviews the limitations of current recycling technologies, including mechanical, chemical, solvent-based, and enzymatic methods and highlights the experimental potential of microbial degradation as a future solution. It also explores innovative approaches, such as upcycling, biodegradable alternatives, and split-layer packaging, which reduce adhesive use and simplify recycling. Legislative frameworks and policy incentives are analyzed to underscore their role in driving technological advancements and fostering industry collaboration. Findings emphasize the absence of a fully viable solution with regard to recycling for multilayer packaging under existing technological and economic constraints. Although “Design-for-Recycling” and emerging methods such as microbial degradation offer promising long-term strategies, temporary measures such as advanced incineration or regulated landfilling may still be required. Moving forward, innovation in recycling technologies, supported by robust policies and collaborative industry efforts, is essential to align multilayer packaging with global sustainability goals and contribute to the development of a circular economy.

This article presents the analysis of molecular and genetic causes of obesity on the example of syndromic and monogenic obesity. The genes underlying the development of obesity are given, and the pathophysiological mechanisms of disruptions in the appearance of mutations in these genes are analyzed. The known mechanisms of obesity are grouped by biochemical disorders in the cell. Defects in cilium structure and associated cell transport and migration; dysregulation in cell signaling pathways within and between cells; dysregulation in transcription, translation, expression, and maturation of biomolecules; defects in biomolecule transport; and energy metabolism disorder are highlighted. All this suggests the possibility of developing not only pathogenetic treatment of obesity based on the normalization of gene product functioning according to the type of disruption, but also a personalized approach to the correction of lifestyle and nutrition, considering the multifactorial pattern of the disease and a certain type of metabolic disorder.
