Published: December 2024

ABSTRACT

Aim and Objective:

The aim of this study was to perform surface and elemental analysis of used titanium and stainless steel miniscrews to investigate their behavior while in association with bone, surrounding tissues, oral fluid, and food.

Materials and Methods:

Fifteen patients were included in this split-mouth study, where in mini-implants were placed between the maxillary second premolar and first molar: titanium mini-implants on the left side and stainless steel mini-implants on the right side. They were placed in the mouth for 4–8 months. Energy dispersive spectroscopy (EDS) was used for the elemental analysis of the retrieved mini-implants and a scanning electron microscope was used to detect the surface changes in the retrieved mini-implants in four areas, namely head, neck, body, and tip. Surface changes and elemental changes were compared between the as-received mini implants and the retrieved mini implants. Surface changes in the form of cracks, craters, deposits, and blunting were observed on the used miniscrews.

Results:

Craters and blunting were seen predominantly in the tip region of the miniscrews, whereas deposits were noted on the head-and-neck region as well. Elemental analysis showed that oxygen, carbon, nitrogen, and calcium were found in significant amount on the retrieved titanium implants, whereas only oxygen and carbon content increase was seen on the retrieved stainless steel implants. The presence of calcium on the retrieved titanium implants could be the reason for its better stability compared to stainless steel implants due to its ability to osseointegrate.

Conclusion:

Surface changes in the form of dullness. loss of gloss, blunting and crater formation were observed, while elemental changes in the form of statistically significant increase in the oxygen, nitrogen , carbon and calcium content were observed on the retrieved mini-implants.
Retinal revelations: Seeing beyond the eye with artificial intelligence
Authors: Akkara John Davis
Published: December 2024

Artificial intelligence (AI) has revolutionized ophthalmology by aiding in the diagnosis, prognosis, and treatment planning of various eye diseases. However, AI’s potential extends beyond ocular conditions. By analyzing eye-related biomarkers, AI can utilize the eye as a window into the body’s systemic health. This field, known as oculomics, leverages AI and deep learning algorithms to process vast amounts of data from imaging techniques such as fundus photography, optical coherence tomography (OCT), OCT angiography, infrared iris imaging, slit-lamp photography, and external eye photography. AI-powered analysis of these images can predict systemic diseases such as Alzheimer’s, Parkinson’s, cardiovascular disease, cerebrovascular disease, chronic kidney disease, and liver disease. Retinal changes —including alterations in the retinal nerve fiber layer, ganglion cell layer, and retinal vessels —serve as valuable indicators of these conditions. Additionally, AI can estimate age, sex, body composition, and other health parameters from eye images. While the potential of AI in oculomics is promising, challenges such as access to ophthalmic imaging, data quality, and the need for rigorous validation must be addressed to ensure its widespread adoption and clinical utility. Nevertheless, AI holds the potential to transform healthcare by enabling early detection, noninvasive screening, and personalized treatment for a wide range of systemic diseases.

Authors: Ravi Alka , Singh Uma Shankar , Kumari Archana , Roy Pummy
Published: December 2024

Objective:

To estimate the incidence of dry eye in post-operative patient undergoing cataract surgery.

Materials and Methods:

Schirmer’s test, tear break-up time (TBUT) test, and lissamine green staining of the cornea and conjunctiva for the evaluation of dry eye preoperatively and again at first and second follow-up examinations at 1 week and 1 month after cataract surgery were performed on 100 patients with senile cataract.

Results:

The patients were 61.25 years old on average, and 71 (71%) of them were men. According to the requirements of our study, none of the patients experienced dry eyes at the time of participation. Schirmer’s test results during the first and second follow-ups, respectively, varied from 12-35 mm and 8-24 mm postoperatively. At the first and second follow-ups, the mean TBUT was 13.12 ± 2.44 and 9.61 ± 2.22 seconds, respectively, whereas the lissamine green staining score was 3 in 66 (66%) and 1 in 62 (62%) patients, respectively. At the initial follow-up, grade 2 dry eye was discovered in 89% of the 56 patients who received phacoemulsification (p 0.001) and in 92% of the 66 patients who underwent small-incision cataract surgery (SICS) (p 0.001). At the second follow-up, 83% of patients who had SICS and 93% of those who had phacoemulsification had grade 0 dry eyes, respectively (p 0.001).

Conclusion:

The incidence of dry eye following cataract surgery was significant and largely unrelated to demographic and anthropometric characteristics, surgical technique, length of microscope exposure, and energy input. This dryness was only temporary in character and exhibited a downward trend, with a tendency to return to normal by the end of 1 month.
A brief review on microphthalmia and anophthalmia
Authors: Periyandavan Jayasri , Stephen Mary
Published: December 2024

Anophthalmia and microphthalmia are congenital eye abnormalities characterized by the absence or underdevelopment of one or both eyes, respectively. These conditions pose significant challenges to affected individuals, impacting both visual function and cosmetic appearance. The etiology of anophthalmia/microphthalmia is multifactorial, involving genetic, environmental, and developmental factors. Diagnosis typically relies on clinical examination and imaging studies, with prenatal detection becoming increasingly feasible through advanced ultrasound techniques. Surgical management forms the cornerstone of treatment, aiming to optimize orbital and ocular growth, enhance cosmetic outcomes, and maximize residual vision. Despite advancements in understanding and management, anophthalmia and microphthalmia remain major causes of childhood blindness, highlighting the ongoing need for research to elucidate underlying mechanisms and develop novel therapeutic strategies.

Published: December 2024

Background:

Amblyopia is due to insufficient development of the visual system in early childhood and affects 1% and 2% population of most developed countries.

Aims and Objective:

(1) Prevalence of amblyopia among adult population attending our hospital. (2) Effect of amblyopia on their academic performance, social life, and on future establishment. (3) Its determinants in a population.

Methods:

This is a prospective, single-center, hospital-based study, where adults between 18 and 60 years were included. A history of ocular trauma, known case of amblyopia, and past ocular surgery were excluded from the study. In this study, amblyopia was defined as best-corrected visual acuity of 20/30 or less or 2-line acuity differences with no pathology.

Results:

Of the total 2880 adults screened, 280 were diagnosed to have amblyopia with a prevalence of 1.75%. Amblyopia was more common among the males (51.1%, N = 143) as compared to females. A maximum number of patients were found in the age group of 20–30. Refractive amblyopia was found to be the most common cause of amblyopia. There was a family history of amblyopia only in 0.7% (N = 2) of cases.

Conclusion:

Awareness of amblyopia among the parents is essential for early detection and treatment of the disease, which will, in turn, reduce the burden of childhood visual impairment.

Published: December 2024

Leydig cell ovarian tumors, rare sex cord-gonadal stromal tumors constituting less than 0.5% of all ovarian tumors, pose both medical and social challenges, particularly for women presenting with symptoms of hirsutism. This study examines the histopathological features of a total abdominal hysterectomy specimen, including bilateral tubes and ovaries, from a 43-year-old female with progressive virilization, deepened voice, and hirsutism over six months. Imaging revealed an ovarian lump, prompting surgical intervention. Histopathological examination of the right ovarian section revealed tumor cells arranged in sheets, nests, and clusters, characterized by polygonal shapes, eosinophilic granular cytoplasm, uniform round nuclei, and prominent nucleoli, along with occasional binucleated and multinucleated cells. Immunohistochemistry (IHC) for Calretinin and Inhibin A was advised, confirming features suggestive of a Leydig cell tumor. The remaining endometrial tissue appeared normal. This case underscores the importance of considering hormonally active ovarian tumors, along with adrenal cancers, in diagnosing postmenopausal hyperandrogenism. Timely diagnosis and treatment through a multidisciplinary approach can lead to significant symptom improvement, as observed in this patient following tumor removal.

Published: December 2024

In assessing the correctness of dentist’s proceedings, the expert opinion plays a crucial role and forms the basis for the decision-making process of the procedural authority. Experts, using their knowledge and experience, while also relying on medical standards and recognized international indicators of orthodontic treatment effectiveness, evaluate the medical proceedings. The aim of the study was to analyse the opinions concerning orthodontic treatment in the material of the Chair and Department of Forensic Medicine of the
Medical University of Lodz. During the examined period from 2016 to 2023, 14 such opinions were issued. These opinions were analysed in terms of case characteristics and primarily examined whether there is a correlation between the orthodontic specialization of the
dentist conducting the treatment and the expert’s assessment of their proceedings. Our analysis indicates that the qualifications of the dentist, understood as holding a specialization, affect the objective quality of orthodontic treatment. In cases where an opinion indicated incorrect proceedings, the error was most often made at the stage of orthodontic diagnosis, leading to the implementation of incorrect treatment. Therefore, dentists without a specialization – although no regulation prohibits them from providing orthodontic treatment – should realistically assess their capabilities before undertaking such treatment. This is particularly important because if they do undertake such treatment, their actions will be judged in the same way as those of specialists..

Published: December 2024

Green synthesis of metal oxides has attracted attention as the latest technology in synthesizing metal oxide nanoparticles due to its simplicity, cheapness, non-toxicity and its ability for large scale production. Metal oxides find applications in dye sensitized solar cells (DSSCs) as counter electrodes (CEs) and photo-anodes. However, applications of green synthesized metal oxides as counter electrodes have not been fully explored. In this study, CuO nanoparticles (NPs) were synthesized from Cucurbita maxima leaf extract and applied as a CE in DSSC. Uniformly synthesized CuO NPs were subjected to various characterization tools to obtain the crystal structure, surface morphology, particle size, optical properties, chemical bonds and photovoltaic properties. Using a natural dye from of Cucurbita maxima as a photon absorber, a short circuit current density ( Jsc) of 4.2 µA/cm2, open circuit voltage (Voc) of 0.17 V, a maximum power (Pmax) of 0.18 mW/cm2, and a power conversion efficiency (PCE) of 1.8 × 10?4 % under one-sun illumination were obtained.
A Pilot Randomized Crossover Study on Stress Responses in Paramedicine Students: Virtual Reality Versus Live Simulation
Authors: Kounovský Ondřej , Bureš Petr , Kuklová Miroslava
Published: December 2024

Introduction: Emergency Medical Workers frequently encounter high-stress situations, such as traffic accidents and sudden deaths, which can negatively affect their mental health. Building psychological resilience through training is essential, and recent methods like virtual reality (VR) gamification have been introduced to improve learning outcomes.
Aim: This pilot randomized crossover study aims to compare the stress responses of third-year Paramedicine students during a severe traffic accident scenario using either a live actor simulation or a VR-based platform (XVR simulation).
Methods:Ten third-year Paramedicine students were randomly assigned to start with either a live actor simulation or a virtual reality scenario using the XVR program. After completing the first scenario, participants underwent a 7-10 day washout period before switching to the alternate scenario. Physiological stress markers, including salivary cortisol, testosterone, and heart rate variability (HRV), were measured before and after each scenario. Subjective stress was assessed using a ten-point visual analog scale (VAS).
Results: No significant differences were observed in cortisol concentration changes (p = 0.576), testosterone levels (p = 0.878), or HRV (p = 0.156) between the virtual reality and live actor simulations. However, students perceived the live actor scenario as more stressful than the virtual reality simulation (p = 0.001).
Conclusion: Both virtual reality and live simulations effectively recreate high-stress scenarios, but students reported higher stress during live actor simulations. These results indicate that VR could be a viable and cost-effective alternative for training Paramedicine students. Larger studies are needed to confirm these findings and assess the long-term impact of VR training on stress adaptation.

The accurate estimation of speed in three-phase induction motors is crucial for their efficient control, operation or diagnostics. Traditional methods often rely on tachometers or encoders, which can be expensive and prone to mechanical wear and tear and can present overkill for applications where knowledge of only the static speed point is of interest. This paper explores an innovative, non-intrusive technique for estimating the speed of three-phase induction motors using sound analysis. By capturing and analyzing the acoustic signals emitted by the motor during operation, it is possible to extract characteristic frequencies corresponding to the rotational speed. Experimental results demonstrate the viability of this method, showing a high correlation between the estimated speed from sound analysis and the actual motor speed measured using conventional methods. This approach offers a cost-effective, reliable, maintenance-free and highly mobile alternative for speed estimation in industrial and educational applications, contributing to the advancement of smart motor control systems. This method is suitable for good estimation of static speed points during laboratory exercises where static characteristics are of interest.

Quorum Sensing’e Gıda Mikrobiyolojisi Perspektifinden Bakış
Authors: Çalışkan Zühal , Dinçoğlu Ahmet Hulusi
Published: December 2024

Tek hücreli canlılarda çekirdek algılama olarak da adlandırılan quorum sensing (QS), bakterilerin sporulasyon, biyofilm oluşumu, bakteriyosin üretimi, virulans tepkileri gibi birçok hücresel işlevini gerçekleştiği bir sinyal mekanizmasıdır. Belirli hücre yoğunluğuna ulaşıldığında, bakteriler tarafından hücre dışı kimyasal sinyaller üretilerek hücreden hücreye iletişim gerçekleşir. Sinyalin (ve hücre popülasyonunun) konsantrasyonu yeterince yüksek olduğunda, hedef gen veya genler ya aktive olur ya da bastırılır. Bu sistem, bakterilerin besinlere veya daha uygun çevresel nişlere erişme yeteneğini arttırır, rakip hücrelere ve strese karşı bakteriyel savunmayı kuvvetlendirir. QS’in fizyolojik ve klinik yönleri çok ilgi görmüş ve moleküler düzeyde araştırılmıştır. Bununla birlikte, gıda bozulması ve gıda patojenlerinin matristeki gelişimi üzerine QS rolü hakkında çok az şey bilinmektedir. Mikroorganizmalar arası bu iletişim sistemi mekanizması detaylı olarak anlaşıldığında gıda endüstrisinde sorun haline gelen patojen ve bozulma mikroorganizmalarının gelişiminin kontrol altına alınması için yeni antimikrobiyal maddeler geliştirilerek hem gıda güvenliğinin sağlanabileceği hem de ekonomik kayıpların da önüne geçilebileceği düşünülmektedir. Sonuç olarak, QS'i anlamak, QS'i bozmak ve manipüle etmeye yönelik stratejilerin geliştirilmesi yönünde çalışmalara ihtiyaç vardır.

Authors: Bayyinah Ayyinah Nur , Helena Putri Zahra
Published: December 2024

Life insurance is one of the non-bank industries that offers guarantees to overcome risks. In its implementation, life insurance companies need to maintain the survival of the company in the midst of increasing economic competition so that they don't face the threat of bankruptcy. Bankruptcy itself is a legal status of a certain entity or company that cannot pay its debts to creditors and the company's operations cannot be continued due to lack of funds. This study aims to compare the accuracy of the Altman Z-Score and Ohlson O-Score methods in predicting the bankruptcy of life insurance companies in Indonesia, such as PT Axa Financial Indonesia, PT Taspen Life, Asuransi Jiwa Bersama (AJB) Bumiputera 1912, PT Avrist Assurance, and PT Reliance Life Insurance Indonesia. The data used in this study is secondary data in the form of financial statements of life insurance companies taken from the official website of the relevant company. The results showed that the comparison between the two models revealed that the Altman method is better in predicting company bankruptcy. This is because the Altman method has a more detailed classification of conditions compared to the Ohlson method.

Authors: Ferrer Joel Cayabyab
Published: December 2024

This study was conducted to determine the academic performance and predictors of the licensure examination for teachers of the Bachelor of Elementary Education (BEED) of Ilocos Sur Polytechnic State College Sta Maria Campus, Philippines, during four consecutive years from 2016 to 2019. This descriptive correlational study involved 299 student takers who took the yearly September Licensure Examination for Teachers (LET). Documentary analysis was used to identify the academic performance in general and professional education courses/subjects from the official transcript of records and the results of the licensure examination for teachers requested by the institution from the Professional Regulation Commission (PRC). Findings revealed that academic performance in general and professional education courses was "very good." A relationship existed between academic performance in general and professional education courses and LET results. General education courses/subjects such as English, Math, Science, and Social Studies and professional education courses/subjects like Theory and Concepts and Methods/strategies were predictors of the licensure examination. However, English is the best predictor. Generally, students performed well in their academics. The higher the academic grades, the better chance of passing the licensure examination. The institutional LET passing percentage is consistently higher than the national passing percentage. The repeaters dragged the national passing percentage down. The overall performance of the graduates during their licensure examination is dependent on how the college equipped the students in taking the said examination.
Ölüm ve Ölümsüzlük: “The Fountain” Filmi Üzerine Çözümleme
Authors: Turhan Gülsüm
Published: December 2024

Çalışmamızda “The Fountain” filminden hareketle insanın doğasındaki sonsuzluğa duyulan özlemi ve ölümle yüzleşme sürecinin karmaşıklığını yansıtmak temel problemimizdir. Film, ölümün insan yaşamında nasıl bir anlam taşıdığını ve insanın ölümle nasıl bir barış içinde olabileceğini vurgu-lamak açısından önemlidir. Din felsefesi açısından ölüm, ölümsüzlük, ölüm ötesi hayat konuları ele alınıp “The Fountain” filmi üzerinden ölümsüzlük arzusu, ölüm korkusu ve bu konularda görüşleri olan filozofların düşüncele-rinin değerlendirilmesi amaçlanmaktadır. Din felsefesi, dinin temel kavram-ları ve inançları üzerine derin düşünceler geliştiren bir felsefe dalıdır. “The Fountain” filmi; ölümsüzlük, ölüm, ruh ve beden gibi konulara dair biyolojik ölümsüzlük ve ruhsal ölümsüzlük olmak üzere iki temel ölümsüzlük anlayı-şını ele alarak bu kavramları din felsefesi ile ilişkilendirmeye olanak sağlar. Biyolojik ölümsüzlük arayışı, insanın maddi varoluşuna odaklanırken, ruh-sal ölümsüzlük arayışı, din felsefesindeki ölümden sonraki varoluş sorusuna yönelir. Filmin, mitolojik öğelerle zenginleştirilmiş derinlikli anlatımı, din felsefesi bağlamında ölümsüzlüğün, ölümün ve insanın varoluşsal arayışının derin anlamlarını keşfetmemize olanak sağlar. Bu çalışmada yöntem olarak metin analizi yapılacak ve “The Fountain” filminin senaryosu, karakterleri, ölüm, ölümsüzlük ve ölüm ötesi hayatla ilgili geçen diyaloglar incelenecek-tir. Çalışmada felsefi ve dini perspektiflerin incelemesi yapılacak, ölüm, ölümsüzlük ve ölüm ötesi hayat konularında farklı filozofların ve dini dü-şünürlerin görüşleri değerlendirilecektir. Film analizinin bir metodoloji ola-rak kullanılması, özellikle simgesel ve metaforik içerikler yoluyla soyut felsefi kavramların daha anlaşılır hale getirilmesini sağlar. Din felsefesi, genellikle soyut kavramlar ve teoriler etrafında dönerken, sinema gibi görsel sanatlar bu soyut konuları somutlaştırarak izleyiciye ve okuyucuya yeni bakış açıları sunar. Bu temalar, geleneksel metinlere dayalı yöntemlere ek olarak görsel-leştirildiğinde, felsefi kavramlar farklı boyutlarıyla incelenebilir. Din felsefesi, günümüz dünyasında giderek disiplinler arası bir yaklaşımla ele alınmakta-dır. Film analizi, felsefe, sanat ve kültürün kesişiminde yer alan bir yöntem olarak bu alanın zenginleşmesine katkıda bulunur. Sinema gibi popüler kül-tür unsurları, toplumun ölüm ve ölümsüzlük gibi derin dini ve felsefi sorun-lara nasıl yaklaştığını göstermede güçlü araçlardır.

Published: December 2024

Introduction. Currently, biomarkers (BMs) of chronic stress and their integral indicators are successfully used in prenosological diagnostics and prediction of progressing of chronic diseases and assessing impacts exerted on health by various environmental factors, including occupational ones.
Materials and methods. We used male workers employed at a metal processing enterprise as an example to examine influence exerted by duration of work under harmful conditions on BM trend and integral indicators of their adaptive conjugacy. The examined workers were aged between 24 and 65 years and their work records varied from 1 to 47 years. The analyzed indicators included the number of significant correlations, the weight of the correlation graph (CG), and correlation adaptation coefficient (CAC). Statistical analysis was performed using the Statistica 10.0 software package.
Results. We determined the average level of 16 individual BMs and 5 integral indicators of neuroendocrine, immunoinflammatory and metabolic processes and functional activity of the cardiovascular system in different age groups of subjects (< 10 years; 10–19 years; 20–29 years; ≥ 30). As a result, we established record-dependent elevated levels of cortisol, C-reactive protein and pro-inflammatory cytokines, cholesterol atherogenicity coefficient, blood pressure, body mass index and waist circumference. The highest values of the latter, above the reference limits, were determined in workers with work records ≥ 30 years. The risk group with the greatest adaptive tension consisted of workers with work records of 20–29 years. The lowest values of G and CCA, identified in workers who had to experience harmful working conditions for ≥ 30 years, could indicate a breakdown of adaptation mechanisms and the body’s transition to a state of allostasis.
Limitations. The study included only male blue-collar workers.
Conclusions. Poly-biomarker approach, including correlation adaptometry, is a preferable tool for population assessment of impacts exerted by duration of contacts with harmful occupational factors as opposed to determining levels of individual BMs.

Introduction. Methods and technologies for assessing and managing risk are becoming the basic mechanisms for ensuring the protection of the health in citizens and the environment from the harmful effects of environmental factors. This is explained by the presence of constant threats associated with the influence of these factors, including the use of modern methods of introducing chemicals during agricultural work. Agricultural unmanned aircraft systems (AUAS) designed to spray pesticides are increasingly being used around the world. The basis for the safe use of pesticides for the population is to minimize the possibility of their spread through the air and settling on the soil outside the treated area, which is ensured by compliance with hygienic requirements for equipment used in agriculture, application regulations, weather conditions during processing, and the size of the sanitary gap between the treated area and settlements, water bodies, etc.
The purpose of this study was to substantiate the safe distances from areas of agricultural application of pesticides using AUAS to objects regulated in accordance with sanitary legislation (settlements, sources of household, drinking and cultural water use, etc.).
Materials and methods. The demolition formed during the application of pesticides of various purposes using AUAS has been studied. The content of drugs carried away by air currents was monitored by measuring the concentration of the substance in the atmospheric air and deposited on the “blue ribbon” filters placed in Petri dishes outside the processing band.
Results. The maximum concentrations of substances in the atmospheric air at all distances from the treatment site were below their hygienic standards for atmospheric air. There is a clear decrease in concentrations in air samples as they move away from the treated area and a nonlinear decrease in concentrations in sedimentation samples with the presence of weak local maxima.
Limitations. A small sample of the studied substances, due to the limited time of the study, does not allow unambiguously identifying the patterns of drift formation depending on their physical-chemical properties, in particular volatility, molecular weight, etc.
Conclusion. The data obtained indicate to the need to continue research for a reasoned correction or confirmation, proposed based on the results of the tests, of the safe distance (700 m) from the sites treated with pesticides to the facilities normalized in accordance with sanitary legislation.

In Brazil, there have been only two recorded sightings of Gervais’ beaked whales to date. In 2001, an individual was found washed ashore in São Paulo (Santos et al., 2003). In the same year (2001), another individual was found washed ashore in Ceará (Martins et al., 2004; Meirelles et al., 2009). On 23 June 2021, a group of three individuals was sighted in offshore waters of southeastern Brazil as part of a monitoring exercise during offshore oil and gas activities. This represents the first recorded sighting of Gervais’ beaked whales in the region and the southernmost record of this species in the southwestern Atlantic Ocean.

Эффективное управление оборотными активами играет ключевую роль в обеспечении финансовой устойчивости и конкурентоспособности торговых организаций. Снижение сроков оборачиваемости активов способствует улучшению ликвидности и повышению операционной эффективности. Исследование направлено на анализ оборачиваемости активов и разработку рекомендаций по оптимизации управления оборотным капиталом в условиях рыночной неопределенности. В работе использованы методы системно-структурного, экономико-статистического и сравнительного анализа при оценке оборачиваемости и ликвидности. Рекомендуется внедрение мер по ускорению оборачиваемости дебиторской задолженности, что может привести к улучшению показателей ликвидности и росту доходности. Перспективы дальнейшего исследования включают анализ влияния макроэкономических факторов на оборачиваемость активов и изучение различных стратегий по эффективному управлению оборотным капиталом.

Authors: Рябичева О.И.
Published: December 2024

В статье рассмотрено состояние перестрахования в России в условиях сложившейся геополитической ситуации, представлены особенности и тенденции развития. Продолжается дальнейшая консолидация страхового рынка. Усилия страховщиков будут направлены на поиск альтернативных перестраховочных емкостей. Рынок перестрахования по своей сути является транснациональным, так как связан с очень крупными страховыми рисками, которые распределяются между странами, поэтому он в большей степени подвержен влиянию санкций. В связи с этим возникает необходимость исследования проблем его функционирования, а также выявления перспективных мер по стабилизации его успешного развития в России.

Further consolidation of the insurance market continues. The efforts of insurers will be directed to search for alternative reinsurance capacities. The reinsurance market is inherently transnational, as it is associated with very large insurance risks, which are distributed between countries, so it is more exposed to the impact of sanctions. In this regard, there is a need to study the problems of its functioning, as well as to identify promising measures to stabilize its successful development in Russia. The article considers the state of reinsurance in Russia under the current geopolitical situation, presents the peculiarities and development trends.
