Background. Among all the new methods and approaches, virotherapy with oncolytic viruses, both in combination with immunotherapy and without it, shows high efficiency in various phases of clinical trials and good tolerance by patients.

Aim. To study the sensitivity of some immortalized cancer cell lines to the R-92 strain of human reovirus with cell characteristics at the ultrastructural level.

Materials and methods. The study was carried out on cell lines of HeLa, A549, U87MG. Cells were planted in an amount of 15 thousand per well of a 96-well plate and after adhesion, the virus was inoculated by adding a medium containing virus particles in 4 tenfold dilutions (approximately 10 9 –106 particles per ml). Next, the cells were cultured for 24 h, after which the number of living cells in the wells was determined indirectly using the methyl tetrazolium test, which was carried out according to standard methods. To study the ultrastructure of infected cells, cells were seeded into a T25 flask and inoculated with the virus at the maximum concentration. After 24 h of cultivation, the cells were fixed in a 2.5 % glutaraldehyde solution in phosphate buffer for 1 h, after which they were washed three times in phosphate buffer and samples were processed for TEM according to standard methods.

Results. Diluting the virus 1000 times led to a decrease in the cytostatic effect in all three cultures to a level practically no different from the control. HeLa turned out to be the most sensitive culture to reovirus. In the experiment, the number of living cells decreased to 60.4 ± 10.2 % compared to the control during incubation with the maximum number of viral particles and to 63.7 ± 16.2 % with a tenfold dilution of the virus. This indicator was significantly lower than in the other two studied cultures under these cultivation conditions (p <0.001).

In addition, at the maximum virus concentration, the A549 culture was less sensitive than the U87MG culture (p <0.01). At lower concentrations of viral particles, the average viability of the studied cell lines did not differ significantly from each other. Analysis of electron diffraction patterns showed that the virus successfully replicates in the cytoplasm of the studied cultures, but is not released from the cell, which is apparently due to the short incubation period. TEM also showed cell damage characteristic of apoptosis or necroptosis, uniformly expressed in all studied cultures.

Conclusion. Cell lines A549, HeLa and U87MG, according to the results of the methyl tetrazolium test, demonstrate different sensitivity to the human reovirus strain P-92. The TEM picture of cells from infected cultures showed signs of the development of apoptosis or necroptosis.

Published: October 2024

BACKGROUND: Augmented reality is a potential alternative for surgical navigation, as it can provide visualization of various anatomical structures of the maxillofacial region. We have developed a specific platform for three-dimensional model management and intraoperative augmented reality navigation for surgical procedures.
AIM: To evaluate surgeons’ perceptions and the usability of augmented reality navigation for the most common surgical procedures in oral surgery.
MATERIALS AND METHODS: We performed a phantom study to determine the accuracy of the augmented reality system in the maxillofacial region. Registration errors typical in image-guided surgery were measured: fiducial registration error, target registration error, and fiducial localization error. Thereafter, a clinical trial with several surgeons performing surgical procedures on jaws using augmented reality technology was conducted. Surgeons filled out a dedicated questionnaire after their experience with augmented reality navigation.
RESULTS: The mean fiducial registration error was 0.9 mm (standard deviation 0.7 mm; 95% confidence interval 0.4–1.3 mm). The mean target registration error was 1.3 mm (standard deviation 0.5 mm; 95% confidence interval 1.1–1.5 mm). The fiducial localization error was the most significant with 2.2 mm (standard deviation 0.9; 95% confidence interval 1.9–2.5 mm). The higher rankings in the user experience questionnaire were related to the novelty and excitement of using augmented reality navigation in maxillofacial surgery. The pragmatic quality aspect explains the technical focus of perception to achieve goals in a product, system, or service design. Efficiency was expected to be slightly higher; however, in our opinion, this is due to the technical difficulties of the system for novel augmented reality technology.
CONCLUSION: The results revealed the satisfactory accuracy of the augmented reality system in the maxillofacial region and the user experience of the augmented reality navigation system for oral surgery.
Orbital dirofilariasis (case report)
Authors: Panova Irina E. , Melikhova Mariya V. , Svistunova Evgeniia M. , Gasanova Ulkar G.
Published: October 2024

Ocular Dirofilariasis is one of the frequent manifestations of this disease. The primary manifestations of dirofilariasis of the visual organ (soreness, redness, itching in the eyelid area) may be nonspecific and weakly expressed at the beginning of the disease. The peculiarity of this disease is that if earlier most cases of human infection with Dirofilaria repens were registered in southern countries and southern regions of the Russian Federation, recently there has been a tendency for this disease to spread to northern regions. Diagnosis of this disease based on the data of instrumental methods of investigation is difficult, although cases of detection of the parasite at the preoperative stage have been described in the literature. This publication presents a clinical case of the orbital form of dirofilariasis, which was diagnosed at the intraoperative stage using transconjunctival access. This access is sufficient for complete removal of the neoplasm, and the rehabilitation of patients after surgery with such an access is short and without the formation of a cosmetic defect. Surgical intervention is the main and only treatment tactic and does not require additional specific antiparasitic treatment.
Neural network model development for detecting atypical mitoses in histological slides
Authors: Berchenko Gennadiy N. , Fedosova Nina V. , Kochan Mikhail G. , Mashoshin Dmitriy V.
Published: October 2024

Background: Modern computer systems allow digitizing and examining images of histological preparations, which led the authors to the idea of using machine learning tools in digital pathohistology. The ability of neural networks to find sub-visual image features in digitized histological preparations provides the basis for better qualitative and quantitative image analysis. Existing machine learning methods provide good accuracy and speed in recognizing various images, which gives hope for their wide application, including in oncologic diagnostics.
AIM: Use methods of mathematical modeling to identify pathological mitoses in histological preparations as the main sign of the difference between malignant and benign tumor growth.
MATERIALS AND METHODS: Histological images of the N.N. Priorov National Medical Research Center of Traumatology and Orthopedics were used as a data set for the neural network model. The model was tested using 188 histologic slides from 67 patients treated at the institute. Histological preparations were scanned on a Leica Aperio CS2 microscope with a ×400 resolution and converted into JPEG format with further processing. Next, the test images were analyzed in streaming mode using the created neural network model in order to obtain the coordinates of the desired diagnostic object — pathological mitosis and the probability with which the model found the object of this category. The obtained images were analyzed by a pathologist to determine whether the detected object corresponded to pathological mitosis.
RESULTS: The authors have chosen an architecture, developed a methodology for training a neural network, and created a model that can be used to detect pathologic mitoses in histologic preparations. The authors do not attempt to replace the physician, but show the possibility of an integrated approach to data analysis by a computer system and a pathologist.
Conclusions: The developed mathematical model of neural network used as a part of technological solution for recognizing pathological mitoses in scanned histological preparations can be used as a tool to reduce the time of research and increase the accuracy of diagnosis by a pathologist.
Nomadic and Settled Worlds: The Mutual Diffusion of Economic Institutions on the Example of the Xi Xia, Liao and Song Empires
Authors:   Institute for Linguistic Research of Russian Academy of Sciences, Kruglova Maria S.
Published: October 2024

There is a commonplace in the historical scholarship that nomadic peoples, adopting a settled way of life, borrow from the agrarian sedentary population their methods of economy managing and state administration. Chinese historical tradition tells that the nomadic periphery fell under Chinese influence and adopted from the Han people both their political and economic institutions. However, sources let us know that the situation is not so simple. There are periods of reverse influence of the nomadic world on agrarian China. In the pre-Mongolian period, the Chinese empire was at the same time at the peak of its development, stood on the threshold of the industrial revolution, but was also heavily dependent on its neighbors, being forced to pay tribute to them. Practices of regular close interaction led to diffusion, that is, the mutual borrowing of various management methods. Using the example of the Chinese Song Empire and its neighbors of the Western Xia and Liao empires, the article shows that borrowings did not always go exclusively from the Han to nomads, but, on the contrary, there was a mutual penetration of both economic and political institutions in the sphere of finance and taxation.
Labour Relations and Modes of Production under Russia's Institutional Development
Authors:   Russian Presidential Academy of National Economy and Public Administration, Didenko Dmitry V.
Published: October 2024

The article contributes to a discussion on the taxonomy of labour relations and its relationships with modes of production in the paradigm of post-Marxian historical institutionalism in the tradition by D.C. North and R.M. Nureev. From this perspective the author provides an outline of the concept of labour relations in Russia/ USSR, with the focus on transition processes. The author traces the transitions from kin-ordered and tributary slavery to serfdom, from tributary and commodified serfdom to wage commodified labour, then to tributary and commodified labour under socialism. The outline is based primarily on the quantitative and qualitative evidence from the previous research literature. From the cross-country comparative perspective the author highlights that the cases of slavery during the early modern capitalism, inherited by the Antebellum Southern United States during the Industrial Revolution, as well as mass use of penall abour during the Soviet industrialization effort, moderately replicated in the pre-reform China, demonstrate resumption of institutions of forced labour on the path to modern economy and society. The evidence indicates that this is associated with the processes of military modernization and expansion of the war economy. In its turn, the weakening of the military threat created the possibility of commodified labour relations development. From this perspective, the trend towards expanding their share was formed in the USSR in the 1950s, and Russia’s transition to market relations in the late 1980s – 1990s appeared to be a new stage in the development of this process.

Varying size and shape of spatial units
Authors: Simonovska Rozeta , Tafenau Egle
Published: October 2024

When an analysis over a specific geographic area is performed, the way that area is divided into regions can affect the outcome of the analysis. Results obtained based on different geographic units can be conflicting. This issue is known as the Modifiable Areal Unit Problem (MAUP). The objective of this paper is to understand the extent to which the regional setting influences the results of an analysis with spatially aggregated variables, with a focus on agglomeration effects, in the case of Germany. Relying on a sample of manufacturing firms over 7 years we estimate a fixed effects model to explain the firm-specific total factor productivity in dependence of region-based agglomeration variables. We simulate 1000 regional settings of Germany on three scales and overtake thereby some characteristics of the administrative units, which are used as the baseline. We infer that the spatial scale and shape matter in the case of Germany.

The Implementation of the National Standards for Higher Education Policy as Quality Assurance
Authors: Rizka Budi , Ibrahim Syafei , Sadhana Kridawati
Published: October 2024

Nahdhatul Ulama (NU) College in Aceh differs from other private universities because it has a complex organizational structure compared to other private universities. Nahdhatul Ulama (NU) College in Aceh, apart from being a higher education foundation leader, must also synergize with the Nahdhatul Ulama (NU) organization. This is what drives the author’s interest in studying the implementation of the National Higher Education Standards in quality assurance improvement at Nahdhatul Ulama College in Aceh. In this study, researchers focused on the implementation of the National Standards for Higher Education Policy at Aceh’s Nahdhatul Ulama Sharia Science College. The method used in this research is descriptive-qualitative. Furthermore, the data source used is the results of interviews with informants, who serve as primary data, and other documents as secondary data. In determining the informants, the researcher used the Purposive Sampling Technique; the data were then obtained through interviews, and documentation was analyzed using the Interactive Model, which follows the flow from data collection, data display, data condensation, and conclusions. Based on the results of research and findings, there are leadership, information technology, infrastructure, finance, university values, and culture, which include attitudes, habits, organizational behavior, work ethics, creating, serving, and interacting with colleagues and the community with good results, all of which contribute to organizational capacity in implementing internal quality assurance at the college. On the other hand, the limited opportunities available to academic staff to enhance their national and international competencies in line with their positions and areas of expertise and the inconsistent application of the PPEPP model at Aceh’s Nahdhatul Ulama College are some of the weaknesses. The implementation of the internal quality assurance system at Aceh’s Nahdhatul Ulama College demonstrated a good strategy; however, there are still areas that require constant improvement in addition to upholding current standards.

Traditional Marriage Culture Among People from Different Nationalities: A Study of Cultural Adaptation in the Gampong Iboih Community, Suka Karya District, Sabang City, Aceh Province
Authors: ‎ Sofyan
Published: October 2024

A marriage between different nationalities is a marriage between two people residing in Indonesia who are subject to different laws due to differences in nationality, with one of the parties being an Indonesian citizen. The process of implementing marriages between nations often requires cultural adaptation. Cultural adaptation in traditional marriages between nations is a process in which couples from different cultures attempt to incorporate elements from their respective cultures into their marriage. This is an important step in understanding and respecting cultural differences, as well as ensuring that the marriage takes place in harmony. Apart from the many factors that support marriage between nations, various factors inhibit marriage between nations, obstacles, and problems that affect the harmony of relationships. Thus, this research aims to describe and analyze cultural adaptations to marriage between nations in the Gampong Iboih community, Suka Makmue District, Sabang City and analyze the supporting and inhibiting factors of marriage culture in the Gampong Iboih community, Suka Makmue District, Sabang City. The research uses a qualitative approach method and the nature of the research used is a descriptive analysis of research case studies. Data sources come from primary and secondary data, and data were analyzed using descriptive qualitative techniques through interviews, observation, and documentation. Interviews were conducted in Gampong Iboih, Suka Makmue District, Sabang City, Aceh Province. The informants in this research were members of community groups who carried out traditional marriages between nations. Results show that the cultural adaptation process resulting from marriage between nations takes the form of language/communication, wedding ceremonies, culinary traditions, and children’s education. The supporting factors for marriage between nations include openness, tolerance between both parties, flexibility, education, and social support. Apart from that, several factors inhibit marriage between nations, namely different values and norms between husband and wife, citizenship and legal issues, and language differences.

Применение цифровых двойников в задачах управления электроприводами обусловлено постоянно возрастающими требованиями к качеству переходных процессов. Цифровой двойник динамической системы представляет собой дискретную модель, применение которой всегда влечет за собой некоторую потерю точности и появление искажений в частотной области. Математические модели кабельных линий характеризуются относительно малыми постоянными времени, что накладывает условия на выбор частоты дискретизации согласно требованиям, предъявляемым теоремой Котельникова–Шеннона. Однако на практике выбор периода дискретизации ограничивается вычислительной мощностью цифрового сигнального процессора. Вследствие этого целью статьи является определение границ применимости в частотной области существующих способов перехода в Z-область методом аналоговых прототипов путем проведения сравнительного анализа погрешности аппроксимации частотных характеристик аналогового прототипа цифровыми моделями RLC-фильтра низких частот для каждого из способов. Установлено, что увеличение периода дискретизации ведет к расхождению между цифровыми моделями и их аналоговыми прототипами в интегральном смысле на всей области частот. Кроме того, это приводит к потере информации о таких физических процессах в реальной системе, как резонанс или изменение фазы сигнала на выходе динамической системы. Для большинства инженерных задач может быть рекомендован метод Тастина при соответствующих допущениях о стационарности динамической системы. Однако при появлении признаков нестационарности или повышенных требованиях к конструированию регуляторов, по мнению авторов, стоит обратить внимание на аналитические модели динамических систем.

La complejidad de la formación doctoral demanda la articulación de distintos aspectos personales y contextuales. En este proceso, el desarrollo de agencia del estudiante es de especial relevancia, sobre todo en situaciones disruptivas que afectan a diversos ámbitos de la vida, tales como el académico y el personal. El presente estudio tuvo como propósito principal analizar las propiedades de la agencia de los doctorandos en el desarrollo de estrategias para el abordaje de la lectura y escritura académicas, el aprendizaje y la optimización del proceso investigativo en la contingencia sanitaria por la COVID–19. A partir de un enfoque cualitativo, se seleccionaron 26 estudiantes de distintos programas doctorales de una universidad mexicana, quienes mostraron llevar a cabo estrategias con un sentido de agencia para el desarrollo de su investigación doctoral. El análisis de la información obtenida se realizó mediante la teoría fundamentada. Los resultados revelan que los procesos de agencia de los doctorandos en vinculación con la lectura, la escritura, el aprendizaje y la optimización del trabajo investigativo se concretizaron en estrategias enfocadas a la gestión del conocimiento y de la información, la gestión espacio–tiempo y la interacción con el director de tesis. En el texto se discuten estos procesos, así como la relevancia de favorecer el desarrollo de agencia desde los programas doctorales a partir de una formación integral (académica, personal, ética, entre otras) que posibilite hacer frente a los retos de los escenarios actuales y futuros.

DİLBİLİMDE ÖZNE VE YÜKLEM İLİŞKİSİNİN MATEMATİKSEL BOYUTU
Authors: İmrağ Özge Sinem
Published: October 2024

Dil, insanlar arasındaki iletişimin temel aracıdır ve insanların günlük yaşamlarında olayları, düşünceleri ve duyguları ifade etmek ve anlamlandırmak için başvurdukları temel yapı taşıdır. Dilin yapısal ögelerinden biri olan özne ve yüklem, cümlelerin temel bileşenlerini oluşturur ve birlikte anlamı tamamlarlar. Matematikteki fonksiyon kavramı, dilde ortaya çıkan özne ve yüklemin mantık ilişkisini anlamak için bir model sunar. Matematiksel mantıkta bir önerme P(x) şeklinde ifade edilir. Bu önerme dilbilim düzlemine uyarlandığında P(x) formülündeki "P" yüklemi, "x" ise özneyi temsil eder ve bunlar değişkenler olarak kabul edilir."x" değişkenine atanan değerler, "P" yükleminin değişmesine neden olur. Dolayısıyla, yüklemin ifade ediliş biçimi özneye bağlı olarak değişiklik gösterir. Bu durum, matematikteki fonksiyon kavramıyla benzerlik taşır. Fonksiyonlar, girdileri belirli bir çıktıya dönüştüren dönüştürücü araçlar olarak düşünülebilir İlgili bağlamda, "x" ve "y" değişkenleri arasında bağlantı kurulduğunda, "x" değişkeni değiştikçe "y" değişkeni de değişir ve "y", "x" değişkeninin bir fonksiyonu olarak adlandırılır. Bir önermede - ya da daha geniş bir çerçevede bir tümcede - özne değiştikçe yüklem de değişeceği için yüklemler, öznelerin bir fonksiyonu olarak nitelendirilebilir. Örneğin Almancada öznesi ich olan bir tümcenin yüklemi komme şeklinde ifade edilirken, öznesi wir olan bir tümcenin yüklemi kommen şeklinde ifade edilmelidir. Bu duruma başka bir örnek olarak ise dil bilgisel olumsuzluk kavramı gösterilebilir. Öznesinde “hiç kimse” veya “hiçbir” gibi mantıksal niceleyicilerin bulunduğu tümcelerde Almanca ve İngilizcede yüklem olumlu yargı taşıyacak şekilde oluşturulurken, Türkçe ve Fransızcada yüklem olumsuz yargı taşıyacak şekilde oluşturulmaktadır. Bütün bu durumlar matematikteki sabit fonksiyon, birim fonksiyon, örten fonksiyon, içine fonksiyon gibi çeşitli fonksiyon türleri ile bağdaşmaktadır. Bu çalışmada özne ve yüklemin tekillik-çoğulluk veya olumluluk-olumsuzluk durumları bağlamında Türkçe, Almanca, İngilizce ve Fransızca arasındaki benzerlik ve farklılıklar fonksiyonlarla ilişkilendirilerek karşılaştırma yöntemiyle incelenmeye çalışılacaktır.
