HOLISTIC AND HUMANISTIC: AN ANALYSIS OF WOMEN HEALTH NARRATIVES IN RURAL INDIA
Authors: Raturi Srishti , Joshi Vishal
Published: October 2024

A female’s physical and psychological being is structured around the roles of belief systems and shared culture. The stigma around women’s health in India incorporates many factors, concepts, and theories. A woman’s diagnosis is seen as biologically biased and the medicine in itself is gender biased in practice. The reductionist approach explains an illness through the biological lens and not much favourable to women. Therefore, a holistic and humanistic approach recognises human illness as a whole concept with social, cultural, political, and personal factors. The medical humanities increase awareness of social, humanistic, and cultural dimensions around health. This paper studies two case study based out of rural India which speak comprehensively of possible prejudice and practices in the health sector. The research draws upon a conceptual study through medical humanities approach. Concluding upon the structures of biomedical discourses and how they can affect the agency of women’s bodies and being, and how gender and illness coalesce to reflect upon a woman’s suffering.

Authors: Lanin Sergey N.
Published: October 2024

The article examines modern approaches to improve the efficiency of logistics processes in natural gas distribution. The main objective of the article is to develop and justify a combined approach for optimising these processes, including the use of graph theory and multi-criteria genetic algorithms to minimise the transportation costs and to maximise the revenue. The study demonstrates that the proposed approach can significantly reduce transaction costs and increase revenue through more efficient management of transport and resource allocation. The paper emphasises the importance of adaptability and flexibility of the logistics system in a dynamically changing external environment. Particular attention is paid to multi-criteria optimisation, which takes into account such important aspects as minimising transport costs, maximising revenue and ensuring security of supply. The proposed approach can be applied both at the national and international level, which is especially relevant in the context of current geopolitical changes and sanctions risks. The author also points out the need for further research to utilise data on available capacity in underground gas storage facilities and the possibility of booking additional transport capacity. The proposed approach is a powerful tool for improving the competitiveness of the Russian gas industry and ensuring the country's economic stability.

Authors: Kovalev Alexander A. , Mezhuyev Alexey V.
Published: October 2024

In the modern world of financial services and banking, lending agencies face increasing competition and the need to constantly improve the quality of customer service. CRM systems allow companies to collect, store and analyze customer data to help better understand their needs and preferences. However, as the customer base and the amount of data grow, it becomes more difficult to analyze information manually and make decisions on personalized offers for each customer. This is where recommender systems come to the rescue. This article discusses the use of various recommender systems for submitting sales offers in CRM, since there is no universal approach to solve this problem. The current state of research in recommender systems and their application in the financial domain is analyzed. The architecture and algorithms for developing of this system are proposed, taking into account the specifics of banking data and business processes. The effectiveness of the recommender system in real bank operating conditions is evaluated.

Introduction. The effectiveness of antitumor immunity is determined by various mechanisms of recognition of tumor antigens, while the diversity of the repertoire of antigenic receptors is determined by V(D)J recombinations in maturing T and B cells. The aim of this work is to review scientific literature data on the role of chromosomal V(D)J recombinations of immune system cells in the mechanisms of antitumor immunity. Material and methods. This review presents data on the main mechanisms of antitumor immunity and the role of T- and B-cell receptor gene rearrangement in its formation. Results. From the presented analysis of literary sources, it follows that carcinogenesis is accompanied by suppression of the antitumor activity of the immune system. As a result, immunodeficiency states are observed in patients with malignant neoplasms. By-products of chromosomal V(D)J recombinations are DNA excision circles TREC and KREC. Their quantitative analysis in cancer patients makes it possible to determine the presence of immunodeficiency, as well as to evaluate the effectiveness of the formation of antitumor immunity. It is also noted that in immunocompromised cancer patients, the possibility of using personalized immunostimulation methods should be considered, which will improve control over the malignant process. Conclusions. The review reflects the mechanisms of the immune system response to carcinogenesis. The main stages of the interaction of the tumor antigen with the patient’s immune system are considered. Methods for evaluating the viability of antitumor immunity are describe

The diagnosis of the disease is made on the basis of category IV criteria, which include data of electrocardiography, Holter monitoring, echocardiography and MRI, laboratory biomarkers of necrosis, inflammation and heart failure, morphological study of endomyocardial biopsy specimens. Objective. To analyze literature data on the potential of different miRNAs determination for diagnostics of myocarditis. Material and methods. Literature search was carried out in Google Scholar for the last 15 years. Results and discussion. miR-208b in blood mononuclear and cardiac tissues can be considered as a promising marker for myocarditis diagnosis, and circulating miR-27b-3p, miR-126-3p, miR-142- 5p and miR-143-3p for DCM diagnosis. The presence of miR-15b-5p and miR-106a-5p in plasma allows us to distinguish between patients with ischemic and idiopathic DCM. Acute viral myocarditis is characterized by the presence of miR-208b and miR-499-5p in cardiac tissues, while fulminant myocarditis is characterized by increased levels of circulating miR-30a, miR-192, miR-146a, miR-155 and miR-320a.

Published: October 2024

Introduction. The review is devoted to the analysis of modern concepts of the neurodegenerative properties of depression. Depression is now regarded as the most common mental illness with significant social consequences. The aim of the study is to determine the pathogenetic role of changes in the metabolism of neurotransmitters and an excess amount of excitatory transmitters in the implementation of the mechanisms of neuronal plasticity disorders in depressive states, leading to the formation of neurodegenerative changes. Material and methods. The scientific literature was searched in the National Library of Medicine (ncbi), PubMed, e-library databases mainly for the last decade. An analysis of the literature data of domestic and foreign sources was carried out using the deconstruction method, aspect analysis, as well as a descriptive method that allows one to be based on «descripts» (depression, neurodegeneration, neuronal plasticity, neurotrophins, neuropeptides), focusing on the most important aspects of the object of study. Results and discussion. The role of pro-inflammatory cytokines, hormones, neurotrophins, neuropeptides in the implementation of the pathogenetic mechanisms of depressive disorder is described. It should be noted a number of advantages of neuropeptides as endogenous regulators of the functioning of the central nervous system, manifested in high physiological activity, the presence of several binding groups for different cell receptors, the regulatory ability to express other signaling molecules, the minimum half-life, the absence of most side effects, the ability to penetrate through the blood-brain barrier, as well as the manifestation of trophic, anti-inflammatory, growth, mediator and effector properties, which leads to a high interest in endogenous peptide compounds and their synthetic analogues as promising therapeutic agents. The lack of a unified theory of the development of depression definitely contributes to an active research interest, which in recent years has been directed to the search for more accurate biological markers of the disease and new therapeutic agents, using innovative achievements in the synthesis of new compounds, as well as the use of agents that have proven their effectiveness and safety

Despite significant advance in clear cell renal cell carcinoma treatment, immune checkpoint inhibitors (ICIs) still have limited therapeutic efficacy. Taking into account the resistance to immunotherapy, observed in malignant neoplasms, the search for predictive markers of response to ICI therapy in patients with clear cell renal cell carcinoma (ccRCC) is under active investigation. Recent scientific studies demonstrate that exosomal miRNAs are key modulators of tumor signaling and determinants of the tumor microenvironment. Dysregulation of miRNAs can affect the immunogenicity of ccRCCs and response to ICI therapy, making them attractive as predictive molecular genetic biomarkers and targets for potential therapeutic developments. The aim of the study was to evaluate the expression levels of exosomal miRNAs-424,-503,-885,-149 in ccRCC patients who received ICI therapy. Material and methods: The study included 42 patients from whom venous blood samples were taken before and after ICI therapy. Expression analysis was performed by quantitative real-time PCR. Results: For miRNA-424 statistically significant differences in expression levels in the comparison groups were demonstrated. It was shown that the expression level of microRNA-424 increased after therapy (M±SM 1.202±0.15) compared with the expression level before treatment with nivolumab (M±SM 0.63±0.17; p-value=0.03). Despite the fact that miRNA-424 and miRNA-503 are clustered, miRNA-503, like other examined miRNAs, did not show any differences in expression levels between the compared groups. Conclusion: miRNA-424 can be used to create a panel of molecular markers within other previously discovered markers to assess the effectiveness of ICI therapy. Despite the fact that this study is pilot and requires validation on larger samples, it confirms the possibility of using miRNAs as additional prognostic markers for ICI therapy.

Published: October 2024

The purpose of this study was to determine the influence of transcardial perfusion, as well as social hierarchy in male mice, on the level of gene expression in the cerebral cortex of mice using the example of the proinflammatory cytokine IL-1β. Material and methods: the study was carried out on non-linear male mice aged 3 months, 10 of which were subjected to stress according to a single prolonged stress protocol. The development of a stress disorder was confirmed by behavioral tests in the “Open Field” and “Elevated Plus Maze” mazes. The control group consisted of 10 mice that were not exposed to any effect. Then, from each group, 5 mice underwent transcardial perfusion, the rest were anesthetized and killed without perfusion. To determine expression levels, mRNA was isolated from the cerebral cortex, cDNA was synthesized, followed by real-time PCR. Results: Mice stressed according to the single prolonged stress protocol demonstrated a rigid social hierarchy, while the behavior of dominant males in the Open Field and Elevated Plus Mazes was significantly different from the behavior of subordinates. As a result of stress in mice, the level of IL-1β expression in the cerebral cortex significantly increases compared to control animals, both in the case of transcardial perfusion and without it. In the control mice group, there was a trend between perfused and nonperfused animals toward lower levels of IL-1β expression in perfused animals, but there was no statistical significance. In the stress group, the expression level of IL-1β was significantly higher in non-perfused animals compared to perfused animals. Conclusion: Our study showed that stress in male mice leads to increased conflicts against the backdrop of a rigid social hierarchy with a clear distinction between dominant and subordinate males. At the same time, the behavior of dominant males in the “Open Field” and “Elevated Plus Maze” mazes differs significantly from the behavior of subordinates, which is reflected in the study statistics. Also, when assessing the expression levels of interleukins in the brain, transcardial perfusion is recommended to remove blood cells from the brain vessels, since the level of expression differs in perfused and non-perfused animals.

Published: October 2024

O câncer de mama é a neoplasia mais incidente na população feminina e sua ocorrência causa grande impacto psicológico, funcional e social. No Brasil, o Ministério da Saúde (MS) preconiza o rastreamento em mulheres de 50 a 69 anos, bienalmente, por meio da mamografia. Este trabalho busca explorar os dados do SUS para entender a dimensão que a mamografia impacta na saúde da mulher. O estudo teve como objetivo analisar os dados de rastreio por meio da mamografia no Tocantins. Trata-se de um estudo epidemiológico descritivo do tipo transversal entre os anos de 2013 a 2021, por meio do Departamento de Informática do SUS (DATASUS), no ícone “Informações de Saúde” (TABNET). A seleção na plataforma foi direcionada à “Epidemiologia e Morbidade” e “Mamografia”. Foram analisadas as seguintes variáveis: ano de realização do exame, sexo, local de residência, faixa etária e escolaridade. Os municípios que mais realizaram mamografias foram em ordem decrescente Palmas (19.340), Araguaína (9.292), Paraíso do Tocantins(4.989) e Gurupi (4.738). O maior índice de exames foi entre 50 a 54 anos. A seleção escolaridade foi ignorada na maior parte desse intervalo de tempo, não sendo possível determinar se o atraso no início do rastreamento do câncer de mama pelas mamografiasou até mesmo a não realização destas se justifica por uma falta de conscientização por uma falta de acesso à informação pela própria escolaridade mais baixa. Em 2021, o Tocantins foi responsável por um total de 28 óbitos por neoplasia maligna da mama. Diante disso, compreender as vulnerabilidades sociais relacionadas com o atraso no rastreio do câncer de mama é fundamental para consolidar as políticas públicas voltadas para a saúde da mulher.

Authors: Faustine Muchui Ndumpa  , Jonathan Kathenge  , Pascal Mwina
Published: October 2024

This paper critically examined the contribution of the concept of philosophic sagacity to the development of traditional African wisdom. Odera Oruka's work primarily centered on identifying and documenting the wisdom of individual sages within African communities, challenging the stereotype that African cultures lack philosophical traditions. The article analyzed the concept of Odera Oruka's philosophical sagacity in the context of Tharaka traditional wise sayings to understand its contribution to the development of traditional African wisdom. There has been an over-emphasis on systematic Western philosophy that has continued to devalue traditional African wisdom which was not only a foundation of African philosophy but also the wisdom behind African traditional societal development. The study used rational-analytical philosophical approach. The study employed postcolonial theory to interrogate the enduring impacts of colonialism on cultures, societies, and intellectual traditions. The study was library-based, drawing resources from published and unpublished works, journals as well as digital sources. The study found that philosophic sagacity has significantly contributed to the development of traditional African wisdom by bridging oral traditions and written philosophy, recognizing the philosophical depth of African wisdom, emphasizing communal knowledge, enriching global philosophical discourse, and inspiring contemporary African philosophers.

Capturing authentic academic ability: The role of mental health in youths’ academic lives
Authors: Nelson R Camp
Published: October 2024

This article examines the critical relationship between mental health and academic performance among youth in the United States of America. By exploring the author’s concept of Authentic Academic Ability (AAA), the article highlights how students' true academic potential can be masked by mental health challenges such as anxiety, depression, and attention-related disorders. These mental health challenges often manifest themselves in truancy issues or poor academic reporting. Recent statistics show the growing mental health crisis among youth, particularly in the wake of the COVID-19 pandemic, and the urgent need for response. The article calls for a reformation in assessment methods, advocating for personalized evaluations that consider mental health as a fundamental factor and personal learning styles. Suggestions include alternative forms of assessment, mental health interventions, and the integration of more contemporary, flexible learning methods such as project-based learning. The author advocates that students should be accurately evaluated based on their true intellectual capacity, devoid of the influence of external emotional or mental health challenges.

The patterns of changes in the electromagnetic radiation absorption characteristics in the frequency range 2.0 – 17.0 GHz of materials based on nickel-containing powdered activated charcoal are presented and substantiated depending on the duration of the process of nickel nanoparticles deposition from aqueous solutions implemented during its production. These materials are made by filling containers formed from a self-adhesive polymer film with particles of such coal. A foil-coated polymer film is attached to one of the outer surfaces of the walls of these containers. The thickness of these materials was 0.3 cm. It was established that their electromagnetic radiation absorption coefficient values in the frequency range 2.0 – 17.0 GHz reach of 0.9. The width of the electromagnetic radiation effective absorption band of materials based on nickel-containing powdered activated charcoal, during the production of which the duration of the process of nickel nanoparticles deposition was 5.0 min, is equal to 10.0 GHz, and for materials based on nickel-containing powdered activated charcoal, during the production in which the duration of the process of nickel nanoparticles deposition was 10.0 minutes and 15.0 minutes, 10.6 GHz and 10.8 GHz, respectively. The average value of electromagnetic radiation absorption coefficient in the effective absorption band of the listed materials is 0.75  rel. units, 0.77 rel. units and 0.82 rel. units respectively. It should be noted that the width of the electromagnetic radiation effective absorption band of materials manufactured in the above manner based on powdered activated charcoal is 6.7 GHz, and their average value of electromagnetic radiation absorption coefficient in the specified band is 0.74 rel. units The studied materials are among the basic materials of electronic technology and can be used to ensure electromagnetic compatibility of electronic devices, as well as microwave devices.

The aim of the work was to study the cycling of composite electrode tin-ultradisperse tin powder in gel-polymer electrolyte based on polyvinylidene difluoride. It was shown by the conducted studies that the cathodic introduction of lithium into the composite electrode tin-ultradisperse tin powder from gel-polymer electrolyte on the basis of PVDF is accompanied by disordered of the initial structure, which reduces the difficulties of the subsequent intercalation and leads to an increase in the lithium diffusion coefficient from 10–14 up to 10–10 cm2/s with increasing stoichiometry of the intercalate. Specific capacity of the electrode with gel-polymer electrolyte is 500 – 700 (mA·h)/g for the first 10 cycles and drops to 110 (mA·h)/g after 100 cycles. The stability of the macrostructure of the electrode during cycling is related to the additional binding effect of the gel-polymer film of the gel-polymer film. Decrease of the specific capacitance during cycling is related to therupture of the gel-polymer film and switching off a part of the electrode surface from the cycling process.To prevent this phenomenon it is necessary to search forgel-polymer electrolyte compositions with increased mechanical stability.

The paper presents the results of the study of the charge accumulation and relaxation mechanisms in the initial and composite films based on polypropylene with filler montmorillonite and high-pressure polyethylene with filler diatomite using methods of thermal activation spectroscopy. It is shown that the addition of a filler into the polymer matrix leads to a change in the polarization mechanism due to the formation of new deep traps at the polymer/filler interface. At the same time, the conductivity of the material decreases due to the hydrophilic properties of the fillers. Numerical estimates of the parameters of electrically active defects (the activation energy and the frequency factor), as well as the relaxation time of the electret state in the studied samples are given, which makes it possible to talk about the possibility of using the studied composite materials as active packaging for food products.

The article presents a laser-acoustic method for spot treatment of AISI 316L thin sheet steel. A special setup has been developed with the use of 3D printing technology for conducting experiments with and without the application of ultrasonic vibrations of 40 kHz and 100 W. An analysis of the quality of the obtained weld points was carried out. A defect such as burn-through was discovered in welded points obtained using the laser-acoustic method. The influence of ultrasonic vibrations on the geometry of the melt pool is shown. It has been established that due to the intensification of flows in the melt bath with the introduction of ultrasonic vibrations, the penetration depth increases. A comparative analysis of the surface area of welded points was carried out using a semi-automatic method. The formation of microstructure was studied. It has been shown that ultrasonic impact provides a fine-grained structure tending to a globular shape.

Carbon structures formed after plasma-induced liquid phase pyrolysis of hydrocarbons were studied. We studied pyrolysis of the products of petroleum refining: fuel oil, heavy catalytic cracking residue, and individual organic substances: furfural, cyclohexane, hexane, isooctane, benzene. The plasma unit generated direct current discharge through graphite electrodes. Elemental composition of the source materials and resulting solid residues was evaluated. Additional heat treatment of solid products was carried out at 900, 1500 and 28000C in argon atmosphere. Specific surface area as well as porous structure parameters of the samples were estimated from nitrogen adsorption data. High-resolution transmission electron microscopy was used to study the microstructure of benzene and fuel oil pyrolysis residues. The relationship between porous structure parameters and relative content of hydrogen (C/H) in the solid residues is discussed. The existence of positive correlation between the C/H parameter and specific surface area has been established. It was also found that with increasing heat treatment temperature, specific surface area decreased for all studied samples. It has been established that the mesopores volume increases, and their average diameter decreases with increase in C/H of solid residues of the feedstock. Micropores volume increases with increasing C/H, whereas their sizes change only slightly. As heat treatment temperature increases, the overall relative porosity decreases. The prospects of plasma pyrolysis combined with subsequent high temperature heat treatment to obtain carbon materials with a controlled porous structure are discussed.

An analytical expression was obtained to estimate the fracture pressure gas inside a closed spheroidal pore, with a crack emanating from the surface of the pore. A linear elastic fracture mechanics (LEFM) approach was used. The fracture pressure, determined by the Irwin brittle fracture criterion, depends both on the size of the pore and crack, and on the shape of the pore itself. As an example, calculations are given for steel 0.5 % C – 1 % Cr and ceramics Al2O3. The dependences of the destructive pressure in the pore on the radius and shape of the pore and on the size of the crack were constructed. It is shown that for steel there is a limiting pore size, below which gas-filled pores with cracks are safe from the point of view of crack resistance, provided there are no external loads. The limitation on the plastic zone at the tip of a crack (LEFM) for steel limits the legitimacy of the presented calculations of fracture pressure according to the Irvine criterion, crack dimensions l ≥ 2,3 mm, and, accordingly, pore sizes a > 2,3 mm.
