Analysis of parsec-scale jet direction variations in active galaxies
Authors:   Moscow Institute of Physics and Technology (National Research University), Kostrichkin I. M.
Published: October 2024

This work is devoted to a systematic study of changes in the geometry of active galactic nuclei (AGN) Jets. We developed a procedure for analyzing VLBI maps to determine the apparent directions of the jets. For 1216 AGN we obtained time dependencies of jet position angles, which allowed us to estimate such physical parameters as: jet rotation velocities and periods of variability. Under the assumption of the presence of binary system, we considered two scenarios for the development of variability in the direction of jet: orbital and precession, and determined characteristic relations of black hole masses and distances between them.

Published: October 2024

We analyzed the change of coordinates of the points of the continuous operating reference stations network of global navigation satellite systems to investigate the regularities of the Earth’s crust movement in the Urals. Access to the measurement data was provided by the PRIN company. Using the GAMIT/GLOBK software, the variations of coordinates of ten base stations during 2022-2023 were investigated. Estimates of station coordinate displacements were obtained: secular trend, amplitudes and periods of variations over a two-year interval.
SDSS-IV MaNGA: Ionization sources of diffuse extra-planar gaseous mediumin disk galaxies of various types
Authors:   Sternberg Astronomical Institute, Lomonosov Moscow State University, Physics Department of Lomonosov Moscow State University, Postnikova V. K.
Published: October 2024

Sources of ionization of diffuse gas at different altitudes in 436 edg^on disk galaxies are explored. The MaNGA data together with theoretical 3MdB models are used. It is demonstrated that models of the gas photoionization in a combination of young OB-stars and hot low-mass evolved stars adequately describe the gas ionization state in the galaxies of all types. Moreover, the fraction of the ionizing flux from OB-stars and the ionization parameter da crease with the altitude, while the role of the ionization by the hot low-mass evolved stars increases. The d^erence in the contribution from these types of ionizing sources correlates with the specific star formation rate and with stellar masses of galaxies. The hot low-mass evolved stars are the principal gas ionization sources in massive galaxies with low specific star formation rate, while OB-stars dominate the gas ionization in low-mass galaxies with high specific star formation rate.

Published: October 2024

Проанализировано, как излучение МЗО проявляет себя в ближнем и среднем ИК-диапазоне, исследована переменность этого излучения. Maser flares can be indicators of the accretion bursts of the associated young stellar objects (YSOs). Recently, a simultaneous brightening in the IR or submillimeter sources and the related maser sources was observed for several objects. Massive YSOs, related to class II methanol masers emission, are usually embedded on a dust cocoon and their emission manifest in the long wavelengths. In this work we have constructed the database of the archive NEOWISE and UKIDSS emission data for more than hundred objects, for which 1.3 mm continuum images were obtained using ALMA. We have analyzed how the YSOs emission occurs in near and mid IR. We also study the variability of this emission.

Published: October 2024

A large amount of observational data has been accumulated for young stellar objects at d^erent wavelengths, and the method of studying the parameters of protostars by modeling the spectral energy distribution has become widespread. Obtaining model SEDs by solving the radiative transfer equation allows one to obtain primary estimates for a wide range of stars, but not all implementations of this method are able to take into account spatial observations of the object. This paper presents extended functionality for the SED Fitter package and Robitaille 2017 models, allowing for spatially resolved observations to be taken into account.

The article describes the analysis of works on monitoring the foundation structures of a construction building and observing the tilt of vertical structures. Over a period of two years, during the construction of the facility, geometric leveling of the foundations is carried out, and the tilt of columns supporting the roof structures is observed. Tilt observations of vertical structures were conducted using two-axis inclinometers and an electronic total station. The construction site is located in an area with complex engineering and geological conditions, resulting in foundations consisting of driven piles with depths ranging from 5 to 38 m. Tilt calculations of the foundation slab were conducted based on measurements of settlement. According to tilt measurements of structures using inclinometers, the tilt increment was determined, and the relationship between the tilt changes of structures and the seasons, as well as temperature variations, was identified. An analysis of the dependency between settlement and tilt of the foundation slab, taking into account the structural features of the object, was conducted on the tilt of vertical structures.
On the dynamics of meteoroid streams originating from NEA collisions
Authors:   Institute of Astronomy of the RAS, Zolotarev R. V. , Shustov B. M. ,   Institute of Astronomy of the RAS
Published: October 2024

Aspects of the formation and evolution of meteoroid streams formed during collisions of NEAs with objects of the Main Asteroid Belt are studied. This collision scenario is considered more probable, since many NEAs, due to their origin, cross the Main Belt region, in which the density of objects is much higher compared to the inner regions of the Solar System. The meteoroid streams originating from collisions have a number of differences from streams of cometary origin, both in terms of the formation of the stream and during further dynamic evolution.
Searching for asteroids with a ”Sintez” telescope in Crimean astrophysical observatory
Authors:   Crimean astrophysical observatory RAS, Nazarov S. V.
Published: October 2024

The study of asteroids is of great importance for science: they store the primary matter of the solar system. The most interesting of them are near-Earth ones, since it is easier for them to send a research probe. They can also cross the orbit of our planet and threaten a collision. The joint ehorts of specialized search telescopes such as Pan-STARRS and CSS made it possible to find hundreds of thousands of main belt asteroids and several tens of thousands of near-Earth ones. However, a significant number of asteroids remain undetected and unexplored due to their small size, low albedo and rapid motion. Asteroids with sizes of the order of tens or a few meters can often be observed only for weeks near the antisolar point or during a close flyby of the Earth. If in such a short period of time we do not have time to obtain sufficient astrometry to predict the movement of the asteroid at the next opposition, we risk losing the object for years. In order to observe weak and relatively fast moving objects, a synthetic tracking method was developed. In this work, we consider the theory and practice of searching for unknown asteroids using this method on a small 350 mm telescope. In two years, we discovered 400 unknown asteroids.

For 5 regions, we determine the probabilities of star membership in clusters and distances to clusters.
Determination of nutation angles based on processing hourly VLBI observations
Authors:   Institute of Applied Astronomy of the Russian Academy of Sciences, Urunova R. M.
Published: October 2024

Over the past 9 years, the IAA RAS has conducted daily observations using the VLBI, with no fewer than six sessions per day. This has allowed exploring the potential for determining nutation angles based on these sessions a The data sessions were processed using a specialized software package developed at the institute, incorporating the global equalization. The results are compared with data from the International Earth Rotation and Reference Systems Service, as well as the annual results of global equalization obtained by the IAA RAS. The accuracy of correction determination depends on the number of combined sessions, making the proposed method promising for obtaining independent data on the coordinates of the celestial pole and studying the free core nutation of the Earth.

Authors:   Saint Petersburg State University, Shishkina E. V. , Morozova D. A. ,   Saint Petersburg State University
Published: October 2024

Quasars sometimes can show rapid variability of the electric vector positional angle (EVPA) of polarization. Periods when the angle changes in an ordered way are called rotations. A detailed study of EVPA rotations provides information about the structure of blazars jets and their magnetic fields. We use a new method for selecting such events to analyze longterm polarimetric observations of the blazar OJ 287. We have found the characteristics of 81 statistically significant EVPA rotations and found out that the rotations of EVPAs in OJ 287 have a dominant direction.
Impact of Acadian Marine Plant Extract Powder (AMPEP) concentration in nutrient medium on the growth and lipid accumulation of Chlorella sp. Culture
Authors: Sarri Jurmin , Erbil Gökhun Çağatay , Elp Mahmut
Published: October 2024

Microalga of the genus Chlorella has developed a stable industry as dietary supplements for humans and animals based on their scientific and commercial interests. The growth of Chlorella sp. cultures has been enhanced by using a variety of nutrients to enhance pigmentation, lipid content, and growth. The use of Acadian Marine Plant Extract Powder (AMPEP) improves agricultural crops and macroalgae production, such as seaweeds. However, AMPEP has not yet been studied as a means of producing microalgae. Therefore, this study investigates microalgae production in a nutrient medium containing AMPEP. Three concentrations of AMPEP were prepared: group A (125 mg L-1 AMPEP), group B (625 mg L-1 AMPEP), and group C (0 mg L-1 AMPEP) as control. Experiments were conducted for each group for 21 days in triplicate. Results revealed that lower AMPEP (125 mg L-1) concentration added to the nutrient medium provides higher cell densities in Chlorella sp. culture. 125 mg L-1 AMPEP in a nutrient medium reached the highest cell density of 1.28 fold cell mL-1 than the control group. Additionally, the dry weight of groups A, B, and C were calculated as 2.57 ± 0.12 g L-1, 1.37 ± 0.06 g L-1, and 1.58 ± 0.16 g L-1, respectively. The cell size of groups A, B, and C were 4.80 ± 1.32 μm, 5.20 ± 1.87 μm, and 3.80 ± 0.79 μm, respectively. Moreover, the highest level of lipid accumulation of Chlorella sp. culture was achieved by group B with a lipid content of 10.44 ± 1.28 %, followed by group A with a lipid content of 8.55 ± 0.80 %, which was higher than the control group (group C) with a lipid content of 7.04 ± 0.93 %. Hence, the present study shows that AMPEP used in microalgae production may improve growth and lipid accumulation.
Neutrosophic Completed Local Binary Pattern Based Grasshopper Species Classification
Authors: Alpaslan Nuh , İlçin Mustafa
Published: October 2024

Locusts are seen as a major threat to the ecosystem because they devastate crops and contribute to thousands of tons food lost every year. Numerous well-trained agents are needed for the efficient control of these insects. However, this is a challenging process. Grasshopper detection methods are being developed using traditional forecasting methods by expert entomologists. The maximum potential of these methods has not yet been completely realized. Hence the majority of work is still done manually. In this paper, a neutrosophic CLBP (completed local binary pattern) based grasshopper species classification framework is proposed. Our proposed system comprises a novel grasshopper species database of over 7.392 images for grasshopper species classification. The grasshopper image is first converted to a neutrosophic field. These discriminatory features are merged with rotation invariant LBP. Our proposed system could achieve up to 99.7% classification accuracy even while working with challenging datasets of wide image quality and size range. The proposed methodology involved diagnosing 11 species and subspecies. It demonstrates the impracticability of conventional diagnostic techniques in the later stages. It could have a big impact on data analysis, enabling more effective handling of global pest.

In the context of global turbulence, the Russian national economy needs positive economic practices of resilience and subsequent development. This need is even greater in regional economies, where a few relatively small growth points, including high-growth firms (HGFs, ‘gazelles’), can become drivers for the entire region. The study analyses the performance of high-growing firms and their impact on regional resilience during the acute phase of the global economic crisis caused by the COVID-19 pandemic (2020–2021). A sample of 11,940 firms (including 403 HGFs) in Sverdlovsk, Vologda, Kurgan, Lipetsk, Orenburg, Chelyabinsk regions, Krasnoyarsk krai and the Republic of Bashkortostan was examined. The research uses such approaches as estimation of the shares of HGFs by number and output and assessment of correlation using the nonparametric method of Spearman’s coefficient. The share of HGFs in the sample as a whole and for each region is consistent with global trends (2-4 %). The industrial structure of high-growth firms differs across regions, meaning that HGFs manifest themselves individually in various regions. ‘Gazelles’ demonstrated a greater ability to preserve jobs during the pandemic in most regions of the sample. For example, while an average employment growth rate was 2 % in 2020, this figure was 25 % for HGFs in Krasnoyarsk krai and Sverdlovsk oblast. During economic recession, ‘gazelles’ positively affect regional resilience in such activities as transport and storage, wholesale and retail trade, and mining. The result is the opposite for manufacturing: a larger share of high-growth companies was characteristic of regions with slower output growth rates for this type of activity in 2020–2121. The findings can be used to substantiate the significance of developing and implementing government support programmes for HGFs at the federal and regional levels.

Published: October 2024

Objectives: The present study focuses on developing La-doped BiFeO3 multiferroic materials for dielectric absorber applications. Methods: The samples are characterized by X-ray Diffractometer (XRD). Further, the morphology is examined using field emission electron microscopy (FESEM) and Transmission Electron Microscopy (TEM). The dielectric parameters and ac-electrical parameters are carried out by impedance spectroscopy. The magnetic properties are studied using a vibrating sample magnetometer VSM, P-E loop. Findings: XRD confirms the rhombohedral (trigonal) structure of BLFO nanoparticles. The grain and particle size values are determined by SEM and TEM, respectively. The dielectric and ac-electrical parameters for all the samples are thoroughly discussed at room temperature. The Maxwell-Wagner or interfacial polarization is noticed at low input field frequencies for x=0.2-0.8. The impedance analysis shows the contribution of grain and its boundary in the electrical conduction mechanism. The multiferroic behavior is examined using M-H loops, P-E loops, and μi-f plots. Novelty: The samples are synthesized by the hydrothermal process to prepare La-doped BiFeO3 nanomaterials.

Published: October 2024

Objectives: The primary objective of this research work is to solve the Profit Based Unit Commitment (PBUC) problem in Power Generation Companies (GENCOs) in the competitive Electricity market. The energy and spinning reserve allocation are considered to maximize the profit of power generation companies. Methods: A new and recently developed optimization technique of Chaotic Sea-Horse Optimizer (CSHO) is planned for an optimal solution PBUC problem. The control parameters of CSHO are the number of Population is 50, the Chaotic map parameter is 4, the dimensions are 10, and the maximum number of iterations is 100 are considered to achieve the global optimal solutions. The competitive study with standard golden approaches of the LR method and other soft computing techniques such as GA, PSO, etc. are considered for performance evaluations of CSHO. The proposed CSHO is mainly based on the natural behavior of Sea-Horse in the ocean. The MATLAB 15.0 platform is utilized for the expected problem. Findings: The CSHO was tested on a standard IEEE-39 bus system (10 generators and 24 hours) with reserve allocation. The CSHO technique improves the total profit of GENCOs with various test loads and reserve demand. The simulation results like Optimal UC schedule, power generation of thermal plants, fuel cost, startup cost, revenue, and profit are displayed. The percentage of total profit of 29.76% is improved when compared with the mathematical approach of the LR method with 102 second time period. Novelty: The CSHO has currently developed an effective algorithm that easily reaches the global optimal solutions. The CSHO mimics the movement, hunting, and breeding behavior of sea-horses in nature. Implementation of chaotic maps helps to improve the convergence speed of the proposed method.

The article discusses the problem of determining the nature of an obstacle using a force sensor for terrain mapping. Three classes of objects have been introduced: the first class is "static" obstacles, the second class is "moving" obstacles, the third class is "unstable" obstacles. To conduct experiments, a simulation system was built in the Gazebo modeling environment, including a manipulator with the ability to horizontally move a probe with a force sensor and a set of obstacles corresponding to three classes of obstacles. All experiments were carried out using the ROS framework, the Gazebo simulator and the Movelt manipulation software. Processing of signals from the force sensor showed that the sig­nals for the three classes of obstacles are different, which makes it possible to identify the class based on sensor readings. Based on the analysis of data received from the sensor, rules were formed that make it possible to determine the class of an obstacle during its interaction with the manipulator in real time. To determine the obstacle class, the values of the force sensor signals are considered, smoothed by the moving average method. According to the rules discussed in the article, an algorithm was developed to determine the class of obstacle, which was implemented in the Gazebo modeling environment. Testing of the algorithm showed the stability of its operation under the given experimental conditions. Successful determination of the obstacle class will allow one not only to construct a map of the area, but also to prevent damage to the device when exposed to a "static" object with excessive force. The presented approach can be expanded to narrower classes of obstacles that characterize objects that can be encountered by a mobile device when mapping a forest area.

Published: October 2024

This article offers a comprehensive interdisciplinary analysis of contemporary popular culture in the United States, with a focus on its development over the past two decades. The research encompasses various theoretical approaches, including philosophical, economic, sociological, psychological, historical, and anthropological perspectives, aiming to provide a nuanced understanding of the complex and multifaceted phenomenon of popular culture within the context of globalization and digital transformation. Attention is given to the impact of recommendation algorithms on popular culture, particularly their role in fostering cultural homogenization, personalizing cultural experiences, and shaping new cultural trends. The issues of cultural hybridization, the ritualization of social practices, and the significance of collective memory in the context of popular culture are also explored. Historical analysis reveals the periodization and evolution of cultural institutions, while the socio-anthropological approach highlights the importance of symbolic structures in the formation of cultural narratives. The philosophical lens emphasizes the postmodern characteristics of contemporary popular culture, including the deconstruction of traditional cultural patterns, and analyzes the dynamics of metaphysical concepts, particularly the idea of presence within the conditions of hyperreality. Sociological methodologies assist in addressing the structuration of cultural practices and adaptive processes of socialization through social networks and other digital platforms, which are emerging as new spaces for the construction of social identities. The psychological analysis focuses on the cognitive and emotional effects induced by popular culture, including cognitive disintegration caused by excessive media consumption, and the impact of social comparison on self-esteem and the psychological well-being of individuals. It is emphasized that popular culture products can be designed to appeal to unconscious desires and internalized norms, shaping motivational structures and social behavior patterns. The economic perspective highlights the processes of commodification of cultural products and the monetization of cultural industries. The article underscores the necessity of integrating these approaches to gain a deeper understanding of how contemporary popular culture in the United States influences global cultural processes and shapes the future directions of cultural practices and social structures. The conclusions emphasize the importance of an interdisciplinary approach that allows for a comprehensive consideration of the impact of popular culture on society, its cultural norms, identities, and social dynamics.
Corporate Hypocrisy. Violations of Trade Union Rights by European Multinational Companies in the United States
Authors:   IRL School Cornell University, Compa Lance
Published: October 2024

Many European corporations adopt American management-style attitudes toward trade unions, notwithstanding their publicly-declared support for global norms on workers’ freedom of association. They exploit US labor laws that violate international standards and interfere with trade union formation. Case studies examine several examples of this anti-union hypocrisy on the part of European firms. At the same time, some European companies have chosen to respect workers’ organizing rights in the United States. The conclusion contains recommendations for securing multinational companies’ respect for workers’ freedom of association in the United States, including application of ILO core standards, UN Guiding Principles, OECD Guidelines, and Global Framework Agreements.

La retribución variable de los consejeros ejecutivos tras la reforma del régimen legal sobre retribución de los administradores de las sociedades de capital
Authors:   Universidad de Castilla–La Mancha, Roncero Sánchez Antonio
Published: October 2024

La retribución de los administradores de las sociedades de capital constituye uno de los aspectos más importantes y controvertidos del régimen aplicable a las sociedades de capital que, en los últimos años, se encuentra permanentemente en el centro del debate público, no sólo jurídico sino también político y social. En el contexto de la reciente crisis financiera, los sistemas de retribución de los administradores han sido directamente señalados como una de las principales causas que han conducido a dicha crisis. Ello ha desencadenado en la generalidad de los ordenamientos jurídicos un nuevo movimiento de reforma del régimen aplicable a las retribuciones de los administradores de las sociedades, sobre todo de las sociedades cotizadas y de las entidades financieras, que en España se ha llevado a cabo fundamentalmente a través de la adopción de normas especiales dirigidas a estas entidades y, sobre todo, como consecuencia de la reforma de la Ley de sociedades de capital por la Ley 31/2014, de 3 de diciembre. En el presente trabajo se ofrece una breve síntesis del contenido y alcance de esta reciente reforma en materia de retribución de administradores y, a partir de ello, se presta especial atención al régimen aplicable a las retribuciones variables particularmente como mecanismo de remuneración de los administradores que desarrollan funciones ejecutivas.

Published: October 2024

This study compares the effectiveness of two automated feedback tools, Google Documents, which will be further addressed as Google Docs, and Merci App, in improving writing ability in French as a foreign language. Forty second-year students used these two reviewer tools to correct their B2-level texts. The data includes 80 student drafts edited on two tools and a survey questionnaire after using these two applications. The results show that both tools help students correct many errors at the sentence, word, and fragment levels but cannot correct errors at the inter-sentence, idea, and coherence levels. Google Docs detects more grammatical errors than Merci App, but Merci App is superior when it comes to finding errors in spelling, vocabulary, expression, and punctuation. Students use the application's error correction suggestions to correct their papers at a very high rate, 92.6% with Google Docs and 81.7% with Merci App. The number of students who prefer Google Docs is also higher than the number of students who prefer Merci App. The study proposes to use both tools to correct students' writing errors and to help students become familiar with error explanations in Merci App to help them systematize language knowledge and develop auto-learning capacity.

The anime genre has gained significant popularity as a source of entertainment, and Spy X Family stands out as a prominent example of this phenomenon. The objective of this study is to examine the violations of the principles of quality and quantity in the Spy X Family. The study is characterized by its descriptive nature and utilizes a qualitative methodology. Observational data was collected by listening and taking notes, and subsequently examined utilizing translational matching methods. A total of four cases of violation of the maxim of quality and four instances of violation of the maxim of quantity were identified in the findings. These infractions are ascribed to the characters' origins as spies, which require them to furnish information that does not accurately represent the real situation.

Published: October 2024

O projeto de estágio, executado por meio da pesquisa-ação, foi desenvolvido para romper com o modelo tradicional de estágio supervisionado, considerado pouco reflexivo e desmotivador pelos discentes do curso de Geografia da Universidade Estadual de Goiás (UEG), câmpus Nordeste. Nesse contexto, o principal objetivo foi proporcionar aos alunos estagiários a oportunidade de vivenciar a docência por meio de pesquisa-ação. A implementação dessa metodologia conferiu um novo sentido ao estágio: os alunos passaram a elaborar projetos, aplicá-los, avaliar as ações executadas e refletir sobre essas ações para atingir os objetivos de ensino e aprendizagem. Esse processo impulsionou os alunos estagiários a resolver os problemas encontrados na prática docente, promovendo um ensino como um processo contínuo e de construção coletiva. Com isso, os alunos assumiram um papel mais autônomo e ativo, podendo se tornar agentes de mudança no contexto escolar em que atuaram.
Experiências pedagógicas com a EJA pelo Brasil: uma atividade extensionista articulando formação inicial e formação continuada de professores

Published: October 2024

Apresentamos uma prática extensionista articulando a formação continuada de professores que ensinam matemática na Educação de Jovens e Adultos (EJA) em redes públicas de diferentes territórios e contextos brasileiros com a formação inicial de estudantes das licenciaturas em Matemática e Pedagogia. O curso de formação, intitulado “A matemática na Educação de Jovens, Adultos e Idosos”, se constitui a partir do estímulo à criação de uma comunidade de compartilhamento sobre a prática pedagógica dos docentes participantes, cerca de 2 por estado brasileiro. No curso de duração anual, com 13 encontros aos sábados, mobilizamos conceitualmente a autoria docente e os currículos como criação cotidiana desses docentes, entendendo-os como respostas e soluções desenvolvidas localmente diante das demandas e problemáticas específicas, contextuais, do ensino de matemática na EJA. Tais respostas e soluções, criadas pelos docentes, são compartilhadas durante a formação, de forma que a cada encontro conhecemos duas práticas pedagógicas realizadas em regiões diferentes do país, a partir das quais propomos atividades de reflexão e de elaboração, promovendo interação entre docentes e estudantes das licenciaturas. Isso permite que os estudantes conheçam um repertório significativo de práticas de docentes brasileiros e seus respectivos e diversos contextos, ampliando seus horizontes para atuação profissional e materializa perspectivas para a curricularização da extensão.

OBJECTIVE: Prostate cancer (PC) ranks second among cancer-related deaths in men, and most deaths are caused by metastasis. Integrins, which are cell surface receptors, play an important role in cancer metastasis. It has been shown that integrin alpha2beta1 expression is effective in cell adhesion, migration, and invasion by increasing binding to collagen I in metastatic PCs. Docetaxel chemotherapy is used in PC, but it is ineffective in advanced stages. Amygdalin is a cyanogenic glycoside commonly found in fruit seeds, there is conflict in the literature regarding its effectiveness in cancer treatment. We aimed to compare the effects of Amygdalin and Docetaxel treatments on the DU145 prostate cancer cell line on integrinalfa2 (ITGA2) and integrinbeta1 (ITGB1) expressions, as well as their effects on cell death, Caspase-3, and Beclin-1.
MATERIAL AND METHODS: Propagated DU145 cells were divided into four groups. Amygdalin was given to the first group, Docetaxel was given to the second group, and Amygdalin andDocetaxel were given together to the third group. They were exposed to the active substances for 24 hours. The fourth group (Control) was not given any substance. mRNA levels of ITGA2 and ITGB1 genes were determined by the Real-time PCR method. Caspase-3 and Beclin-1 staining were performed immunocytochemically to evaluate cell death.
RESULTS: There was an increase in ITGA2 and ITGB1 expressions in the groups administered by Amygdalin and by Docetaxel (P<0.05). The decrease in ITGB1 expression was significant in the group given Amygdalin+Docetaxel (P<0.001). Caspase-3 (P<0.05) and Beclin-1 (P<0.05) immunoreactivities were observed to increase in all three groups compared to the control group.
CONCLUSIONS: It was observed that Docetaxel increased cell death more than Amygdalin in DU145 PC cells, and when Amygdalin and Docetaxel were used together, ITGA2 and ITGB1 expressions were significantly reduced. Our results suggest that dual treatment of Amygdalin and Docetaxel may prevent prostate cancer metastases.

OBJECTIVE: Nerve injuries, often resulting from various causes, pose serious health issues that typically require prolonged rehabilitation. Conventional methods used in the treatment of these injuries are often inadequate, necessitating the exploration of new treatment approaches. Research on the effects of plant-derived active compounds on nerve regeneration may offer potential new treatment options. In this context, this study investigating the effects of Myrtus communis on nerve regeneration aims to fill an important gap in the field of nerve injury treatment.
MATERIAL AND METHODS: In this study, the efficacy of Myrtus communis was evaluated in an experimental sciatic nerve injury model. Thirty-two female Wistar Albino rats were divided into four groups: Control, Sham, Group I, and Group II. Sciatic nerve injury was induced, and Myrtus communis treatment was administered via gastric lavage. The animals' motor functions, sensory functions, electrophysiological measurements, biochemical parameters, and histopathological evaluations were examined.
RESULTS: The results demonstrated that Myrtus communis contributed to rapid improvement in sciatic functional index (SFI) values. Similarly, positive effects were observed in sensory assessment and electrophysiological measurements. Biochemical analyses indicated that Myrtus communis increased antioxidant capacity and reduced oxidative stress. Histopathological examinations revealed less axon degeneration, edema, and vacuolization in the groups treated with Myrtus communis.
CONCLUSIONS: This study concludes that Myrtus communis could be used as a potential therapeutic agent in the treatment of sciatic nerve injury. These findings suggest that Myrtus communis may play a supportive role in post-nerve injury recovery. However, it should be noted that further research is needed before these results can be translated into clinical applications.
