GENOMIC INSTABILITY IN ONCOCYTIC FOLLICULAR ADENOMA OF THE THYROID
Authors: Zh. Kozykenova , G.S. Shalgimbayeva , Zh.B. Mussazhanova
Published: October 2024

Oncocytic follicular adenomas of the thyroid are neoplasmas of follicular cell origin that are predominantly composed of large polygonal cells with eosinophilic and granular cytoplasm. However, the pathological characteristics of these tumors are the largely unexplored. The diagnosis of malignancy is reliably based on histological evidence of capsular invasion or vascular invasion, extrathyroidal local tissue invasion, and nodal or distant metastasis. Both the initiation and progression of cancer can be caused by an accumulation of genetic mutations that can induce genomic instability.

Онкоцитарная фолликулярная аденома (ОФА) диагностируется при отсутствии доказательств о капсулярной и сосудистой инвазии, а также при отсутствии ядерных особенностей папиллярной карциномы при щитовидных поражениях заключенных в капсулу, также и онкоцитарная фолликулярная карцинома диагностируется при проявлении как сосудистых, так и\или капсулярных инвазии при отсутствии ядерных особенностей папиллярной карциномы. Тем не менее, клиническое значение онкоцитарного изменения в опухоли щитовидной железы остается неясным и спорным. Диагноз злокачественного новообразования надежно основывается на гистологических данных о капсулярной или сосудистой инвазии, инвазии в экстратиреоидную локальную ткань и узловых или отдаленных метастазах. Как возникновение, так и прогрессирование рака может быть вызвано накоплением генетических мутаций, которые могут вызвать нестабильность генома.

Онкоцитарлық фолликулярлық аденома капсулалық және тамырлы инвазия белгілері болмаған кезде, сондай-ақ қалқанша безінің капсулдалған зақымдануында папиллярлық карциноманың ядролық белгілері болмаған кезде диагноз қойылады, ал онкоцитарлық фолликулярлық карцинома капсулалық және тамырлы инвазия белгілері болғанда диагноз қойылады. Дегенмен, қалқанша безінің ісігіндегі онкоцитарлы өзгерістің клиникалық мәні түсініксіз және даулы болып қала береді. Қатерлі ісік диагнозы капсулалық және тамырлық инвазияның, экстратиреоидты жергілікті инвазияның, орталықты және шектелген метастаздардың гистологиялық көріністерімен нақты негізделеді. Қалқанша безі ісіктерінің онкоцитарлық өзгерістерінің клиникалық маңыздылығы түсініксіз және даулы болып қалуда. Қатерлі ісіктің пайда болуы және дамуы генетикалық мутациялардың жинақталуымен себеп болады, өз кезегінде геномдық тұрақсыздыққа әкелуі мүмкін. Осы зерттеменің мақсаты- қалқанша безі фоликуллярлық ісіктері онкоцитарлық түрінің геномдық тұрақсыздығының дәрежесін бағалау болды.
Репрезентация бытовой терминологии в аварской топонимии
Authors: З. М. Оцомиева-Тагирова
Published: October 2024

Общественное сознание активно влияет на формирование топонимии на выбор названий. Проявление жизнедеятельности географических названий складывалось веками и стало важной частью материальной и духовной культуры народа. Топонимы появились в определенную историческую эпоху и часто отражают особенности жизни людей. Географические названия – это исторические памятники, отражающие быт и мировоззрение людей, их имена, хозяйственную деятельность и многое другое. Топонимы для науки могут многое сказать, если их расшифровать вовремя, тщательно и правильно, поскольку каждое название – это слово, которое развивается по лингвистическим законам, отражая национальную культуру, традиционную хозяйственную деятельность, родной язык и письменность. В данном случае определение бытовых терминов в топонимии, которая является неотъемлемой частью исторического и культурного наследия аварского народа, в настоящее время является актуальным вопросом. Основная цель работы – продемонстрировать топонимическую систему, отражающую экономическую активность географических названий аварцев.

Tick-borne encephalitis is a serious zoonotic infectious disease prevalent in various regions of the Eurasian continent, including the Republic of Belarus. This article examines the clinical features of tick-borne encephalitis as well as modern serological and molecular-genetic diagnostic methods that enable the verification of this diagnosis. Emphasis is placed on the interpretation of enzyme-linked immunosorbent assay (ELISA) results, and on the capabilities and limitations of available laboratory verification methods for tick-borne encephalitis, depending on the phase of the infection. An algorithm for the differential diagnosis between tick-borne encephalitis and the most common bacterial tick-borne infections in the Republic of Belarus is proposed, along with an algorithm for laboratory verification of tick-borne encephalitis.
Atrial fibrillation and atrial flutter in the practice of the emergency medical team in Poland
Authors: Jastrzebski Paweł , Szajda Sławomir D. , Kupcewicz Ewa , Kowalska Ewa , Miłowski Tadeusz , Nowak Marcin
Published: October 2024

Background: Atrial Fibrillation (AF) is one of the most common heart arrhythmias globally. It is characterized by irregular, chaotic contractions of the atrial muscle, leading to an irregular and often rapid heart rhythm. The prevalence of this arrhythmia increases with age, which is associated with both the aging population and cardiovascular risk factors such as hypertension, coronary artery disease, and diabetes. Atrial Flutter (AFL) represents a less common variant of atrial fibrillation, occurring significantly less frequently - in relation to atrial fibrillation (AF), it is estimated to account for less than one-tenth of cases. The aim of the study was to analyze emergency medical services delivered to patients diagnosed with atrial fibrillation (AF) and atrial flutter (AFL) in the Voivodeship of Warmia and Mazury (Poland). The patients were classified according to the 10th Revision of the International Classification of Diseases (ICD-10 )[1]. Methods: The study was based on a retrospective data analysis. From a total population of 400,251 subjects (n= 400,251), 4715 patients were selected for the study. The majority of the patients were women (n=2941; 62.38%), whereas men accounted for 37.62% of the examined sample (n=1774). The analysis relied on a database administered by the Governor of the Voivodeship of Warmia and Mazury in Olsztyn [2]. The analyzed data included the area of intervention, the patient's age and sex, and the diagnoses made by physicians, paramedics, and emergency nurses. Three research hypotheses postulating the presence of relationships between the patient's sex and the diagnosis (1), the patient's age and the diagnosis (2), and a life-threatening emergency and the patient's age (3) were formulated. Results: The results of the study suggest that the patient's sex affects the medical diagnosis. In particular, women were more frequently diagnosed with chest pain, whereas the probability of the remaining diagnoses was similar in both sexes. The patient's age does not significantly influence the diagnosis. The patient's sex is not a significant predictor of a life-threatening emergency. Conclusion: The conducted study on the dataset from the Warmian-Masurian Voivodeship revealed significant correlations between demographic variables and the diagnosis of atrial fibrillation (AF) and atrial flutter (AFL) in patients. Analyzing this data may have significant implications for emergency medical systems, enabling the adaptation of intervention strategies to different patient categories.
The impact of perioperative education and the use of psychologist's advice on the quality of life, including sexual life, of patients with intestinal stoma
Authors: Paszyńska Wiktoria
Published: October 2024

Objective: The aim of the analysis was to assess the impact of perioperative education and the use of advice from a psychosexologist on the quality of life, including sexual life, of patients with an intestinal stoma. Methods: Data were collected from 150 stoma patients. The Patient Identification Form, Body Esteem Scale (BES), Female Sexual Function Index (FSFI), and International Index of Erectile Function (IIEF) were used to compile and evaluate data. Results: An analysis showed that patients who received comprehensive information in the post-operative period about stoma care and management were less likely to report complications. In the study conducted, there was no evidence of an impact of the use of psychological or psychosexual counselling on the body image and sexual functioning of patients with an intestinal stoma. Conclusion: Postoperative education is an important element in reducing the number of postoperative complications and is an important way to achieve independence related to stoma care.

Dissolving pulp was treated with ammonia gas at 20 °C at different pressure levels. The modified pulp was analysed with regard to the change in crystal structure from cellulose I to III. X-ray diffraction and Raman spectroscopy were used as analytical methods. It was found that the transformation of cellulose from cellulose I to III takes place above a defined pressure level, which could be recorded continuously as a function of pressure. Below the characteristic pressure level, the cellulose is still present as cellulose I after treatment. This pressure level is lowered by the presence of water. The ammonia gas is therefore able to swell the crystalline areas of the cellulose starting from a defined process intensity, causing the cellulose to recrystallize in a different structure. Finally, the cellulose III obtained was partially converted back into cellulose I by water boiling.

Published: October 2024

The textile industry is consistently integrating cutting-edge technologies, introducing materials with multifaceted features, such as odour resistance, hydrophobicity, durability, and self-cleaning capabilities. This transformation is facilitated by the application of nanotechnology. The focal point of this experimental endeavour lies in closing the gap in employing ZnO nanoparticles on high GSM denim fabric, enhancing self-cleaning, UV protection, and antimicrobial capabilities. Initially, a solution containing nanoparticles, binder, softener, ethanol, and their auxiliaries was formulated. Zinc oxide nanoparticles, along with their auxiliaries, were applied to the denim using the pad-dry-cure and pad-dry-steam methods. Various trials were conducted to optimize the concentration of ZnO NPs, with the formulation containing 5% ZnO NPs, 5% binder, and 25% ethanol. Experimentation ensued to establish optimal time–temperature profiles for drying, curing, and steaming. Comprehensive evaluations, including drop tests, stain tests, colour strength assessments, crocking tests, SEM analysis, antimicrobial testing and UV protection factor determination were conducted on the samples. The study revealed that fixation of the self-cleaning finish by curing gives better results than by steaming. SEM examination highlighted the distribution of ZnO nanoparticles on the denim fabric. Lastly, antimicrobial properties were assessed, concluding that treated fabrics exhibited antibacterial activity compared to untreated fabrics.
Methods and tools to support the Experimental Programme “Dateci spazio”
Authors: Baratta Adolfo F. L. , Calcagnini Laura
Published: October 2024

The European Community has adopted a contractual-performance mode of managing community funds, in which the funding disbursement is contingent on the achievement of specific measured results. This has conditioned the NRP Programmes and had positive repercussions on national ones. Among these, the “Dateci Spazio” Programme (literally “Give us space”) is part of a broad process of equitable and inclusive regeneration of urban habitats and green infrastructure, promoting the creation of playgrounds in municipalities with populations over 300,000. The paper returns application research aimed at defining a process and tools to implement this experimental Programme generating accessible, inclusive, and universal habitats.
Coastal Greenways in Italy: an Environmental Infrastructure Awaiting an Integrated Territorial Project
Authors: Clemente Antonio Alberto , Nanni Angelica
Published: October 2024

Greenways, territorial fragilities, and landscape are distinct themes. This is evident from the comparison of projects for the five coastal greenways already implemented in Italy on abandoned railway tracks. The aim is to overcome this separation by envisioning the greenway as an environmental infrastructure that serves as a catalyst for a broader territorial project, as achieved by San Rafael, Melbourne, and Enschede. The perspective is to utilise rain gardens, bioswales, and stormwater tree trenches to transform the greenway into a permeable body where existing and planned vegetation provides opportunities to rethink open space in terms of ecosystem services. This new design concept is also beneficial for the fourteen greenways scheduled for future implementation.
Regenerative and innovative processes in the urban and peri-urban area of the city of Rome
Authors: Cornice Alessandra , Innamorati Alessandra
Published: October 2024

Rome stands out for a fragility that stems from the disordered interpenetration of its rural soul with its urban agglomeration. The relationship between city and suburbs still appears complicated today and reverberates on the degree of social cohesion of its inhabitants. Bottom-up experimentation projects are being grafted into the extended area of the capital, reviving disused public property, abandoned land, to eliminate degradation especially in fragile contexts, developing regenerative processes of active citizenship. The purpose of the paper is to underline innovative experiences, in the urban and peri-urban area of Rome, pointing out their actions aimed at sharing common values, developing territorial welfare and protecting the environment.

The paper presents the results of a third-party research project defining the process of redevelopment and social and environmental regeneration along the historic urban axis of Via Nazionale and Corso Vittorio Emanuele II in Rome. The site is affected by the construction of the new tram line connecting Termini Station to the Vatican City. The study proposes an approach to the design of public spaces that, starting by inhibiting traffic from rubber-tired vehicles and private cars and the application of environmental mitigation strategies, allows to reduce pollutant emissions, enhance the cultural heritage along the urban axis, and revitalise cultural, social, and commercial activities, thus triggering a virtuous process of sustainable growth and development.
Common values for common goods: a circular regeneration model for active citizenship
Authors: Ciampa Francesca , Bosone Martina
Published: October 2024

Regenerating cultural heritage implies adopting a systemic and multi-scalar approach capable of considering the characteristics and flows of relations between the different components of the system. The regeneration project can be a circular strategy to reconnect people and places, generating and regenerating material and immaterial values of cultural heritage as a ‘common good’. The research proposes a circular and participatory regeneration model, validated through an evaluative framework. It supports decision-making and assesses the multidimensional impacts of reuse, redevelopment, maintenance and management practices of the commons, at all stages of the recovery project, and with respect to emerging instances and criteria adopted in existing policies.
Confiscated property from illegality to common good: requirements for a necessary resignification
Authors: Germanà Maria Luisa , Antonica Cosimo
Published: October 2024

The property confiscated from organised crime is the outcome of a particular communing process. Italian law provides for a primary compensatory function, implemented in the final destination of their use for collective, institutional, or social purposes. Despite the critical management issues, which prolong the allocation process, the strong symbolic value is enriched by the significance of compensation for the mafia oppression that certain territories suffer. In addition, confiscated properties constitute a potential resource for the territory from an economic point of view, capable of supporting job opportunities and enhancing useful services and activities for the community involved. The resignification of confiscated property requires specific focus on the various phases of the interventions. It is not just a question of a mere change of legal status or intended use but of a profound reorganisation of the architectural, material, technological, environmental, and managerial characteristics. This is consequent and consistent with the interweaving of legal, social, cultural and environmental aspects triggered by confiscation.
Constructing with ruins. José Ignacio Linazasoro: buildings for marginalised places in Madrid
Authors: Panzini Nicola
Published: October 2024

Spain’s large cities have long suffered from decay and crime in the central areas, and the impoverishment and depopulation of smaller towns located in the crown. Madrid is such an example. The Lavapiés neighbourhood was a site of rampant unauthorised building practices. Formerly a shelter for sub-Saharan migrants, it is now among the best known to the tourist masses, which, however, mask its delinquency and social deterioration. Instead, the rural hamlet of Valdemaqueda has shrunk to its current number of six hundred inhabitants. Its economy is limited to religious pilgrimages, thus risking the disappearance of the local community. José Ignacio Linazasoro (1947), a Spanish architect living and working in Madrid and winner of the International Brick Award and of the Piranesi Prix de Rome, took on the task of ‘healing’ the Lavapiés neighbourhood and the Valdemaqueda hamlet through the integrated construction of two ruins with strong civic value.

Objective: In infancy, the most common cause of bladder outlet obstruction is Posterior urethral valves (PUV), which impair renal and bladder function. This study was planned to evaluate and record the role of MCU in the various clinical presentations and management, complications, surgical management, and long-term outcomes of PUV. Methods: In this study, 49 patients treated for PUV were evaluated at the Bangladesh Shishu Hospital and Institute from May 2018 to April 2021. Complete data were taken, paraclinical examinations were performed on each patient, and the diagnosis was confirmed by micturating-cysto-urethrography (MCU). Posterior urethral valves were ablated in all patients using an electric hook. Results: A total of 49 patients with a mean age at diagnosis of 42(±21) days were included in this study. Catheterization was done within one to 5 days of life in 29 patients. PUV was ablated by an electric hook in all 49 patients. The most common symptoms in our group were dribbling, poor stream (71%), and urinary tract infection (UTI) (46%). There was vesico-ureteral-reflux (VUR) in 52% and hydronephrosis in 92.5%. The most common associated anomaly was kidney anomalies (Renal agenesis/dysplasia and multicystic kidney disease) in 4(8.2%) patients. About ten patients had prenatal diagnosis of PUV. Complications occurred in two (4.2%) patients. Mortality occurred in 3 (6.4%) patients. The mean follow-up period was 3.2±0.8 years (1.5 months to 4 years). Conclusion: MCU is the gold-standard imaging modality for documenting PUV and Postoperative follow-up to assess the condition of the posterior urethra urinary drainage by catheter in the early days of infancy. The factors like renal dysplasia and UTI have their role in the outcome.
Improving Water Productivity in Irrigated Agriculture: A Review of Techniques and Water Conservation Methods in Ethiopia
Authors: Meskelu Elias
Published: October 2024

Water is a scarce resource and the competition for it is increasing from time to time due to population growth and economic status change. The population growth leads to high expectations to produce more food from irrigated agriculture which could not be satisfied by rain-fed conditions. As irrigated agriculture is by far the largest water consumer in an inefficient way, improving water productivity has paramount importance both for the production of more food and for wise utilization of scarce water. Beyond these, studies suggest that improving water productivity in Ethiopia contributes to an increase in the irrigated area, reduced competition, and conflict between users, increased profitability due to reduced labor cost, water pumping and working time, and generally increased food production. Different water productivity improvement techniques and water conservation methods have been tested in different parts of the country. These include improving the performance of irrigation schemes, regulated deficit irrigation practice, partial root zone drying, application of irrigation on selected crop growth stages, supplementary irrigation, drip irrigation, surge and cutback irrigation, and water conservation methods like mulching and integrating irrigation with conservation agriculture. The level of water productivity improvement varies considerably for different methods, study areas, crop types, and seasons. Generally, more studies concentrated on deficit irrigation and irrigation application at different crop growth stages. Water conservation and integration of cultivation practices with efficient irrigation led to an improvement in water productivity. Despite few studies, scheme-level study results suggest that the level of deficit irrigation should be selected based on the available irrigation water and cultivable land area for maximizing the benefit of the scheme. According to the economic profitability, crop types and crop varieties also should be selected for production with site-specific conditions. Despite different types and levels of reduced irrigation leading to lower crop yield, the inclusion of the economic importance is essential as most crops showed higher water productivity at lower irrigation levels. On the other hand, studies on the integration of different water productivity enhancement techniques and crop planting patterns are minimal in the country, though current studies revealed better water productivity. Moreover, basin-level water productivity improvement studies could contribute to alleviating water competition and increasing irrigated areas. Therefore, studies on the optimization of these different methods could be done at the basin level for better water resource utilization. Government policies should also focus on water productivity improvement for the implementation of research findings.
Ho Chi Minh’s Ideology on Environmental Protection and that Ideology’s Significance of Environmental Protection Awareness Education for Students
Authors: Ngoc Ha, Nguyen
Published: October 2024

During the process of leading the country, Ho Chi Minh soon outlined strategic directions for the country’s development, including the issue of environmental protection. Educating environmental protection awareness for all classes of people, especially the young generation, is of great significance. The young generation, including youth and students, is a part of society that the Communist Party of Vietnam always pays attention to training and nurturing; they will become the core force shouldering the responsibility of the country’s future. The purpose of this study is to clarify Ho Chi Minh’s Ideology on environmental protection, and the significance of that Ideology in educating environmental protection awareness for students today. To achieve this goal, the study uses disciplinary and interdisciplinary research methods in social sciences and humanities. Research results have shown that Ho Chi Minh’s ideology on environmental protection is still valuable today. At the same time, inheriting those values for environmental protection education activities for students will bring about great changes in the awareness and actions of Vietnamese students. Proposing necessary solutions will help universities improve the quality of environmental protection education for students at present and in the future.
Bravery and Friendship in Children's Literature through the Lens of Van Dijk's Critical Discourse Analysis
Authors: Jesudas Roseline , Alteib Inass Ahmed
Published: October 2024

This research utilizes Van Dijk's (1977) Critical Discourse Analysis (CDA) framework to investigate the themes of bravery and friendship in the children's stories "The Brave Little Squirrel" and "Milo's Magical Map." The primary objective is to examine how discourse influences social identities, values, and interpersonal relationships through narrative structures and character dynamics. Using qualitative methods, the study conducts a detailed textual analysis focusing on thematic elements, character dialogues, and the moral lessons delineated in both stories. The findings indicate that these narratives portray bravery not solely as a heroic quality but as an expression of aiding others, thereby nurturing a sense of community and companionship. Additionally, the analysis uncovers the underlying social values presented in these narratives, underscoring the significance of empathy and collaboration for young readers. This research enhances the understanding of children’s literature as a crucial factor in shaping social and moral growth, offering valuable insights for educators and parents regarding themes that can effectively instill positive values in children.

Cities are at the Centre of South Africa’s Wage Inequalities
Authors: Visagie Justin , Dlamini Msawenkosi
Published: October 2024

Transformation of the South African labour market is imperative for building a more equitable and prosperous future. The ‘triple challenge’ of inequality, poverty, and unemployment all have their roots in a slack domestic labour market.1 Yet, to date, the majority of scholarly work on labour market outcomes in South Africa has focused on micro supply-side issues, or, in other words, on the barriers that exist in the lives of workers, particularly among the youth.2 Demand-side macro factors, by contrast, such as the impact of technological change, globalisation, and urbanisation, have been largely neglected.
Are Banks Doing Enough to Address Inequality?
Authors: Coetzee Johan
Published: October 2024

President Ramaphosa indicated in the 2023 State of the Nation Address that a state bank “will provide financial services to SMMEs, youth- and women-owned businesses, and underserved communities” on the back of the Postbank’s infrastructure and a pending banking licence.1 This ‘developmental agenda’ has been reiterated by several government officials in recent years, including former South African Reserve Bank Governor Tito Mboweni2 and current Secretary General Fikile Mbalula,3 although Minister of Finance Enoch Godongwana stated in 2022 that South Africa cannot afford such a bank.4 At its core, such a state bank is seen by the South African government as a key enabler to address the inequality problem in South Africa as part of their broader developmental policy agenda.
АНАЛИТИЧЕСКАЯ ОЦЕНКА ПЕРВОЙ ЧАСТОТЫ СОБСТВЕННЫХ КОЛЕБАНИЙ РЕШЕТЧАТОЙ ФЕРМЫ ПОЛУРАСКОСНОГО ТИПА
Authors: М.Н. Кирсанов
Published: October 2024

Балочная регулярная ферма с параллельными поясами имеет сложную раскосную решетку. Методом, основанным на упрощенной формуле Донкерлея, получена аналитическая зависимость первой (низшей) частоты свободных колебаний конструкции от количества панелей. Предполагается, что стержни фермы массы не имеют, а вся масса равномерно распределена по узлам. Рассмотрены только вертикальные колебания узлов. Жесткость конструкции рассчитывается по интегральной формуле Мора. Сравнение аналитического решения с численным показывает высокую точность полученной зависимости. Все преобразования выполнены в системе компьютерной математики. Обобщение серии частных решений на произвольное число панелей выполняется методом индукции. Численно анализируется спектр собственных частот, выявляются спектральные константы и зоны резонансной безопасности.
ПОСТРОЕНИЕ ЯДРА СЕЧЕНИЯ ДЛЯ ПОПЕРЕЧНОГО СЕЧЕНИЯ, ОГРАНИЧЕННОГО ПОЛУПЕТЛЕЙ ЛЕМНИСКАТЫ
Authors: Л.В. Пахомова , О.В. Щербакова , Н.С. Инкижинов
Published: October 2024

Данная работа, как и [1], имеет общую кривую – лемнискату, ограничивающую поперечное сечение стержня. Однако в предыдущей статье поперечное сечение имеет одну ось симметрии, в то время как в данном исследовании поперечное сечение, представленное полупетлей лемнискаты, не имеет осей симметрии. Учитывая сходство и различие указанных поперечных сечений, одна часть геометрических характеристик будет общей, а другая – отличается. Для кривой линии, ограничивающей контур поперечного сечения, применяется непрерывный способ, а для прямой линии, являющейся осью симметрии (Ox), используется дискретный способ построения ядра сечения.
