The development of Russian-Iranian trade relations in the context of transition to free trade
Authors: Kozyrev A. S. 
Published: January 2025

Relevance. The article examines the development of foreign trade relations between Russia and Iran in the context of transitioning to a free trade regime. The relevance of the topic is driven by the growing importance of economic cooperation between the two countries against the backdrop of geopolitical changes and sanctions pressure from Western states.The purpose of the study is to identify key trends and factors influencing bilateral trade between the studied countries, as well as the risks associated with Iran's integration into the free trade zone of the Eurasian Economic Union.The objectives of the research include studying the foreign trade profiles of the two countries, examining the dynamics, structure, and trends of bilateral trade, and identifying the potential for mutual trade between Russia and Iran.Methodology. The methods used include statistical analysis of time series, calculation and analysis of the export similarity index, and comparative analysis of statistical data on bilateral commodity flows.The results obtained include the calculation of the export similarity index values for Russia, Iran, and their key trading partners. The index values indicate a high similarity in the exports of Russia and Iran and highlight the risks associated with Iran's integration into the free trade zone of the Eurasian Economic Union due to potential intensification of competition. The analysis of the structure and dynamics of commodity flows showed that the export of goods from Russia to Iran has transformed, with Russian suppliers losing their position in Iran's market of iron, and agricultural products now forming the basis of the export commodity flow. Imports of goods from Iran to Russia also primarily consist of agricultural products. At the same time, there is an observed growth and diversification of imports, facilitated by sanctions isolating both countries from global markets and pushing them towards strengthening bilateral cooperation. The analysis of complementary commodity flows indicates that there is unfulfilled potential for growth in bilateral trade across various industries. Iran's integration into the free trade zone of the Eurasian Economic Union and the removal of trade barriers could serve as a powerful stimulus for the rapid development of trade relations.The conclusions of the study indicate a slow development of trade relations between Russia and Iran, primarily due to Iran's protectionist policies, currency crisis, low competitiveness of Iranian goods, and underdeveloped infrastructure. However, the intensification of cooperation, including the removal of trade barriers and the development of the "North-South" transport corridor, is contributing to the growth of trade turnover. A significant step has been the establishment of free trade agreements, which have already begun to yield tangible results.

Relevance. Modern realities are such that society is becoming more and more aware of and realizing its rights to a decent life, among which there is the right to housing as a basic characteristic that further determines the behavior and consciousness of a person. Housing should be safe in the first place, and then affordable, in connection with which we can talk about the need to develop such measures of housing policy in Russia that would reflect the essence of our country as a social state, acting exclusively in the legal field during the implementation of various housing programs with care for the person and citizen of its state.The purpose is to analyze the implementation of state policy in the field of housing and communal services in the Kursk region on the basis of legislative and statistical data.Objectives: to characterize the essence, structure and main legislative acts in the field of housing and communal services regulation; to study the effectiveness of the implementation of regional projects in the field of housing and communal services in the Kursk region.Methodology. In the processing of factual material, traditional scientific approaches were used – dialectical and systemic. The methods of comparison, statistical analysis and ranking were used as research tools.Results. Currently, housing and communal services perform two functions that are different in meaning and content. The first is a social function that functions as an element of the social protection system of the population, and the second is an economic function, since it provides housing and communal services to the population. The interdependence and opposite orientation of these functions determine the contradictions and problems that arise in social processes with the continuous consumption of living space and utilities.Conclusions. The main goal of the development of housing and communal services in the Kursk region is to improve the quality and reliability of housing and communal services, improve housing conditions, increase the protection of the housing stock and the level of housing and communal services for citizens in accordance with the current quality standards.

Authors: Ringeval Mickaël , Etindele Sosso Faustin Armel , Cousineau Martin , Paré Guy 
Published: January 2025

Background
Digital twins (DTs) are digital representations of real-world systems, enabling advanced simulations, predictive modeling, and real-time optimization in various fields, including health care. Despite growing interest, the integration of DTs in health care faces challenges such as fragmented applications, ethical concerns, and barriers to adoption.

Objective
This study systematically reviews the existing literature on DT applications in health care with three objectives: (1) to map primary applications, (2) to identify key challenges and limitations, and (3) to highlight gaps that can guide future research.

Methods
A meta-review was conducted in a systematic fashion, adhering to PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines, and included 25 literature reviews published between 2021 and 2024. The search encompassed 5 databases: PubMed, CINAHL, Web of Science, Embase, and PsycINFO. Thematic synthesis was used to categorize DT applications, stakeholders, and barriers to adoption.

Results
A total of 3 primary DT applications in health care were identified: personalized medicine, operational efficiency, and medical research. While current applications, such as predictive diagnostics, patient-specific treatment simulations, and hospital resource optimization, remain in their early stages of development, they highlight the significant potential of DTs. Challenges include data quality, ethical issues, and socioeconomic barriers. This review also identified gaps in scalability, interoperability, and clinical validation.

Conclusions
DTs hold transformative potential in health care, providing individualized care, operational optimization, and accelerated research. However, their adoption is hindered by technical, ethical, and financial barriers. Addressing these issues requires interdisciplinary collaboration, standardized protocols, and inclusive implementation strategies to ensure equitable access and meaningful impact.
Histopathological Comparison and Expression Analysis of COL1A1, COL3A1, and ELN in the Proximal and Distal Ventral Dartos of Patients With Hypospadias: Protocol for Prospective Case-Control Study
Authors: Raharja Putu Angga Risky , Birowo Ponco , Rachmadi Lisnawati , Wibowo Heri , Kekalih Aria , Duarsa Gede Wirya Kusuma , Abbas Tariq , Wahyudi Irfan 
Published: January 2025

Background
The exact cause of penile curvature in hypospadias remains unknown. Resection of the dartos fascia has been observed to straighten the penis, indicating the involvement of the dartos fascia in the superficial chordee. However, the characteristics of dartos tissue in the distal territory of the ventral penile shaft may differ from those in the proximal aspect of the penile shaft.

Objective
This study aims to investigate the distinct histopathological profiles and expression of COL1A1 (collagen type 1), COL3A1 (collagen type 3), and ELN (elastin) in proximal and distal ventral dartos of patients with hypospadias compared to those without hypospadias.

Methods
This prospective case-control study compares the ventral dartos tissue of patients with hypospadias at different locations with that of patients without hypospadias. Dartos samples will be taken during surgery, with age matching. Histopathology examination uses hematoxylin and eosin and Masson’s trichrome stain. The mRNA expression of COL1A1, COL3A1, and ELN will be quantified using a 2-step reverse transcription–polymerase chain reaction analysis.

Results
Previous studies have documented different characteristics of dartos tissue between patients with hypospadias and those without hypospadias. Some studies even suggest resection of the dartos tissue during hypospadias repair. However, this is the first study to compare the characteristics of ventral dartos tissue in patients with hypospadias based on its location along the penile shaft, suggesting potential differences between the distal and proximal locations. We have obtained ethical approval to conduct a prospective case-control study aimed at elucidating these differences in dartos tissue characteristics. The findings of the study are anticipated to be available by 2025.

Conclusions
Differences in the characteristics of dartos fascia based on its location may require tailored surgical strategies. If the properties of distal dartos tissue closely mirror those of typical dartos tissue, the possibility of avoiding its excision during hypospadias surgery could be considered.

Published: January 2025

Precooling is a critical process in the post-harvest activities of vegetable and animal products. This research aimed to evaluate the relationship between animal products’ physical, mechanical, and chemical parameters and their relationship with the treatment combination of compressive force, cooling media, and type of animal product samples using a compressive type plate cooler. The research was carried out with three types of meat (beef, chicken, and fish), three compressive forces (0, 100, and 200 kg), and two types of cooling medium (ice cubes and dry ice). The results showed that PCA using XLSTAT could be used to reduce the number of parameters to two main components which could explain 75% of the total variation in the data set. PCA was able to group precooling treatments with cooling media based on the physical, chemical, and mechanical properties. Treatments using ice media for all types of meat and compressive forces were grouped in quadrants I and II, while those using dry ice media were grouped in quadrants III and IV. Based on the type of meat sample, the results of PCA were able to group beef and chicken samples in quadrants I and IV, while tuna fish samples were in quadrants II and III. Keywords: Animal product, Cooling medium, Force compression, P recooling, PCA.

Published: January 2025

Red palm oil (RPO) is known for its high carotenoid content, particularly β carotene and α-carotene, which provide significant provitamin A activity. However, it is susceptible to oxidation during frying and results in nutrient loss and quality degradation. This study investigates the effects of high temperatures and prolonged heating durations on the chemical and sensory properties of RPO. The experiment involved heating RPO at three different temperatures (140°C, 180°C, and 220°C) for durations ranging from 2 to 10 hours. Chemical analysis included peroxide values, free fatty acids, and changes in functional groups through Fourier Transform Infrared (FTIR) spectroscopy. Sensory evaluations focused on aroma and color alterations due to heating. Results showed that prolonged heating of RPO at high temperatures led to significant increase in peroxide values, and the formation of oxidation products, including aldehydes and ketones, which negatively impacted the sensory qualities. The oil darkened, and a burnt aroma developed, reducing overall sensory appeal. These findings provide new insights into the optimal frying conditions to preserve the nutritional and sensory qualities of RPO, particularly by minimizing heating duration and temperature. Keywords: Nutritional value, Prolonged heating, Red palm oil, Sensory attributes, Thermal oxidation.

Published: January 2025

This research was conducted to explore the effectiveness of combined Trickling Filter (TF) and Rotating Biological Contactor (RBC) method in processing liquid waste from chicken slaughterhouses through local and economical media. Microorganisms were grown by inserting liquid waste into a TF tank containing gravel, used ceramics, coconut shells, and pumice. Subsequently, liquid waste flowed into a rotating biological contactor added with local microorganisms from stale rice and fermented banana stems. Waste treatment was carried out with variations in retention time of 1, 3, and 6 h. The results showed that at 6 h, the organic compound decreased significantly. The removal efficiency obtained was 87.05%, 82.11%, 90.51%, 22.57%, 79.36%, and 88.66% for Biological Oxygen Demand, Chemical Oxygen Demand, Total Suspended Solids, Total Dissolved Solids, Turbidity, and Ammonia, respectively. This high efficiency was supported by the collaboration between the activity of microorganisms attached to the TF biofilm and the use of local microorganisms in decomposing organic compounds in the rotating biological contactor. The combination of the two methods has been proven to help waste treatment process from chicken slaughterhouses in an environmentally friendly and efficient manner. Keywords: Biofilm, Chicken slaughterhouse waste, Local microorganisms, Rotating biological contactor, Trickling filter.
