Purpose: to analyze and systematize scientific and methodological sources on hand-to-hand combat for primary school children and compare them with studies conducted in other types of martial arts. Material and methods. The work used the method of analysis of scientific and methodological literature, as well as Internet sources. The literature search was carried out using the Google Scholar database and other academic resources, such as PubMed and ResearchGate. The search for literary sources was carried out in Ukrainian and English. Results: the results of the study emphasize the significant role of martial arts classes, in particular hand-to-hand combat, in the development of physical and psychological qualities of primary school children. The analysis of the literature allowed us to identify key areas of research: the development of coordination and agility, moral and volitional qualities, as well as the introduction of innovative approaches and modern technologies into the educational and training process. It was found that hand-to-hand combat classes contribute to the development of physical fitness, improvement of social skills and increased motivation for physical activity. Considerable attention is paid to the introduction of elements of martial arts into school programs, which makes physical education lessons more effective and interesting for children. Some studies emphasize the importance of developing basic self-defense skills that are formed in the process of practicing hand-to-hand combat. The important role of competitive activity, which is an integral part of the initial training of athletes and contributes to the improvement of technical and psychological skills, is also noted. Conclusions. Based on the analysis of the literature and research, it can be concluded that the systematization of existing research confirms the feasibility of using hand-to-hand combat as an effective means of physical and psychosocial development of children of primary school age.
A NEW MEDIUM: THE JOURNEY OF THE GRAPHIC NOVEL AS AN ARTISTIC EXPRESSION
Authors: Ходоренко А
Published: February 2025

Background. This article explores the defining characteristics and cultural significance of graphic novels as a legitimate literary and artistic medium. It highlights their distinctive narrative structures, artistic styles, and thematic depth, emphasizing how these elements contribute to their complexity and richness. The study addresses the pursuit of cultural legitimacy within graphic novels, tackling the stigma traditionally associated with comics and advocating for their recognition as serious literature.
Purpose. The purpose of this article is to define the unique attributes of graphic novels in order to clarify their role as representatives of visual literature. To achieve this aim, we will address several objectives: 1) to analyze the narrative and artistic components of graphic novels, 2) to illustrate how these elements amplify marginalized voices through autobiography, 3) to evaluate the impact of the book format on narrative delivery and reader engagement, and 4) to critique the binary distinction between fantasy and reality in graphic novels.
Methods. The study employs descriptive methods of investigation, enabling a comprehensive multimodal analysis of the graphic novel format and its syntactic components.
Results. The findings reveal that autobiography plays a significant role in graphic novels, enhancing their ability to foster social commentary and amplify marginalized voices. Additionally, the materiality of the book format influences narrative delivery and reader engagement, while the critique of fantasy versus reality uncovers nuanced representations of truth within the genre.
Discussion. The final perspective is to analyze translation variants and examine how the relationship between text and image is reflected in different languages. This exploration underscores the capacity of graphic novels to engage with socio-political themes and contribute to public discourse, positioning them as a dynamic and impactful medium that transcends traditional literary boundaries and enhances cultural understanding.
ЕПІЗОД ЯК ОДИНИЦЯ ІНТЕРСЕМІОТИЧНОГО ПЕРЕКЛАДУ
Authors: Хуторна Г.
Published: February 2025

Постановка проблеми. Інтерсеміотичний переклад, або переклад між різними знаковими системами є одним з найбільших викликів у сучасному перекладознавстві. Наразі не розроблено єдиного підходу до дослідження та аналізу цього явища. Особливо недостатнім є інтерес українських дослідників до інтерсеміотичного перекладу, що внеможливлює швидку інтеграцію досвіду зарубіжних дослідників та вироблення власних методологійних засад.
Метою дослідження є виявлення та аналіз особливостей інтерсеміотичного перекладу на матеріалі екранізованого літературного твору, а основне завдання полягає у дослідженні процесу інтерсеміотичного перекладу, зокрема, екранізації літературного твору, у такий спосіб, що за одиницю аналізу взято епізод.
Методи дослідження. Застосовано метод суцільної вибірки для створення масиву елементів дослідження, зіставний метод для зіставлення і порівняння елементів літературного твору та його екранізації та описовий метод для опису відмінностей досліджуваних явищ.
Основні результати дослідження. У сучасному вітчизняному та європейському перекладознавстві наразі не існує ґрунтовних праць, які розглядають одиниці інтерсеміотичного перекладу. Однак епізод може виступати одиницею інтерсеміотичного перекладу, адже він є передусім відносно завершеним складником твору, що дозволяє відділяти один епізод від іншого для вдалого аналізу. Отже, аналіз процесу інтерсеміотичного перекладу (зокрема, екранізації) передбачає насамперед визначення рівнозначних епізодів у двох медіаформатах відповідно. Під час такого інтерсеміотичного аналізу видається можливим докладно розглянути процес перекладу та відповідні мультимодальні відношення.
Висновки і перспективи. Повний збіг літературних та кінематографічних епізодів та їхніх компонентів не є можливим, оскільки мова літератури та мова кіно функціонують за різними законами та послуговуються різними інструментами, а тому певні елементи будуть вилучені в процесі перекладу; рідше можливе додавання нових елементів. Цей аспект, зокрема, становить особливий інтерес для досліджень, оскільки під час будь-якого перекладу є неминучі втрати, а розуміння сутності цих втрат може бути помічним для пошуку шляхів удосконалення перекладу, а також для побудови нових моделей перекладу.

Published: February 2025

Violanthin, a compound isolated from the stems of Dendrobium officinale, exhibits potent antioxidant and antibacterial activities. However, no research has been conducted on the identification of violanthin in mouse plasma using UPLC-MS/MS. The present study aims to develop a selective UPLC-MS/MS method for the quantification of violanthin in mouse plasma. Samples were prepared using acetonitrile for protein precipitation, with aconitine as an internal standard (IS). Chromatographic separation was achieved on a UPLC HSS T3 column with acetonitrile and 0.1% formic acid as the mobile phase. Quantification was performed in multiple reactions monitoring (MRM) mode, targeting fragment ions m/z 579.6→457.2 for violanthin and m/z 646.6→586.5 for IS. Mouse blood samples were collected at different time points following intravenous (4 mg kg−1) and oral (30 mg kg−1) administration of violanthin. The calibration plots for violanthin in mouse plasma exhibited a linear trend across the entire range of 5–2,000 ng mL−1, with both intra-day and inter-day precision RSDs below 10%. The bioavailability was determined to be 24.3%. This UPLC-MS/MS method effectively facilitated pharmacokinetic studies of violanthin in mice.

Published: February 2025

Uma das características centrais na identificação dos casos de TEA é a comunicação peculiar das pessoas diagnosticadas. Os indicadores de linguagem não verbais para o diagnóstico de TEA em crianças tem sido bem documentado nas pesquisas de observação em contextos de interação social. Contudo, há necessidade de se investigar também os aspectos verbais por meio destas metodologias. O objetivo principal deste estudo é identificar as habilidades e os comprometimentos sociopragmáticos na linguagem verbal de uma criança com TEA, em comparação com uma criança sem TEA, no contexto de interação com a mãe. Pretende-se identificar os comportamentos repetitivos e estereotipados na linguagem verbal e no comportamento da criança, além de dificuldades na habilidade de conversação. Como objetivo secundário pretendeu-se avaliar a adequação de um protocolo de observação construído para avaliar os aspectos sociopragmáticos na linguagem verbal de crianças com TEA. Trata-se de um estudo de casos comparativos, de cunho descritivo e exploratório. Participaram deste estudo 2 crianças (uma com diagnóstico de TEA e outra sem TEA), com 5 anos de idade, e suas mães. Os resultados das sessões de observação demonstraram que foi possível identificar comprometimentos sociopragmáticos especificamente na criança com diagnóstico de TEA. O que mais diferenciou os dois casos foi a forma como a criança com TEA interagiu (dificuldades na prosódia e na atenção compartilhada, ausência de relato e presença de expressões estereotipadas e ecolalias) e pela dificuldade de coordenar o olhar com a fala.  O protocolo parece ter cumprido seu objetivo, mas ainda necessita de revisão.
The Role and Mandate of the Motor Industry Ombudsman of South Africa: Addressing Prospects and Challenges to Enhance Consumer Protection
Authors: Tshabalala Thapelo , Magau Phemelo
Published: February 2025

The Motor Industry Ombudsman of South Africa (MIOSA) is an industry ombud recognised under the Consumer Protection Act 68 of 2008 (CPA). The MIOSA regulates the interaction and provides for alternative dispute resolution in the automotive and related industries in South Africa. Moreover, the MIOSA is an impartial organisation that focusses on the resolution of disputes where a deadlock has been reached between the automotive and related industries and their customers, as well as relationships among participants in the automotive and related industries to the benefit of the parties. The role of the MIOSA is to make recommendations in cases referred to it where parties cannot reach common ground and are unable to arrive at mutually acceptable agreements following a dispute. This analysis explores and proffers possible solutions to address the challenges that impede the MIOSA from discharging its role and mandate under the CPA effectively in resolving consumer disputes in the South African automotive industry.
Challenges experienced by South African police officers when taking statements from victims with a communication disability: An exploratory study
Authors: Viljoen Erna , Tonsing Kerstin, M , Bornman Juan
Published: February 2025

Police officers increasingly come into contact with persons with a communication disability in their line of duty. This study describes the challenges officers face when taking statements from such victims. Focus group discussions were conducted with South African police officers. Findings showed that they face a myriad of challenges in the statement-taking process. These could be categorised under four main themes: the transactional nature of communication, lack of resources to support communication during statement-taking, the vulnerability of complainants with communication disabilities, and police pessimism. The article recommends that disability sensitivity training, as well as training on communication disability, be provided to police officers.
Theoretical framework for Open Distance Learning: a South African case study
Authors: Alba Kotzé Derica
Published: February 2025

This paper outlines the elements of a theoretical framework for open distance learning (ODL) in a developing country through the application of the case study method. The theoretical tenets of transactional distance and connectivism have been applied to investigate the feelings, perceptions and expectations of Honours students in Development Studies at the University of South Africa (Unisa). With a special focus on students’ access to and usage of the internet and web-based learning, the study contributes to developing a framework for distance education in a developing context. In addition to a literature study and theoretical framework, a quantitative research approach was followed and entailed an exploratory study based on survey research. The results show that the vast majority of students are willing to engage fully with e-learning and are active internet users considering it as an important source of learning and information. However, it is important to note that access and usage of the internet depend on the individual profile of a student. In conclusion, elements to inform the design of an ODL theoretical framework are outlined.
Burning to Be Men? Conspicuous consumption as a performance of masculinity in the activities of Izikhothane in Tembisa
Authors: Mnisi Jabulani Goodhope , Frassinelli Pier Paolo
Published: February 2025

Burning to Be Men? is a study that investigates the role of consumption in the performance, enactment, and pursuit of masculinities in the subculture of ukukhothana. The phenomenon of ukukhothana involves township youths who predominantly come from impoverished economic backgrounds who engage in conspicuous consumption. The fieldwork was conducted in Tembisa, the second largest township in Gauteng, in the East Rand. I worked with The Good Fellas, which is one of the longest running and most popular crews in the area of Phomolong. Studying the consumption patterns of people is a very complex undertaking. This is particularly the case in the South African context, given that consumption studies as a discipline have mostly been developed outside of Africa. Finding a single theory to study a peculiar South African subculture such as ukukhothana was a challenge. In order to get over this challenge, I relied on multiple theories. I used theories of consumption, subculture, masculinity, and evolutionary psychology. When all of these are combined, they provide a lens through which I could read the consumption behaviour of izikhothane. Being a closely-knit subculture, gaining access to The Good Fellas was not easy. However, the ethnographic method that involved prolonged observations made it possible to create rapport with the members of this crew and successfully collect the data. The data that I present in this study was gathered by attending the events that The Good Fellas attended as well as by conducting individual interviews with them. I analysed my findings through the use of Discourse Historical Analysis (DHA) and Multimodal Discourse Analysis (MDA). The analysis of the data reveals that The Good Fellas are indeed burning to be men both literally and figuratively. In the literal sense, the burning entailed the theatrical destruction of valuable items of clothing in order to get esteem from their peers, while the figurative burning speaks of their internal desire to attain and demonstrate masculine identity in line with perceived societal expectations of what it means to be a man. For the members of this crew, being a man is not a state of being but rather a state of doing. The Good Fellas subscribe to the belief that masculinity is earned through behaving in a certain manner, and conspicuous consumption is at the centre of this behaviour. However, conspicuous consumption is not an end in itself but rather a means to end. It serves as a vehicle to demonstrate their abilities as men to hustle, provide, and be responsible. Though ostentatiousdestruction is part of the subculture, the findings suggest that it only occurs in the early stages of the group and disappears as the group evolves through age and its establishment as a popular crew. It is clear from the findings that consumption is evolutionary and plays a significant role in the communication of masculinities among The Good Fellas.

Published: February 2025

Introduction: Goiter is a localized or diffuse hypertrophy of the thyroid gland. During its evolution, this hypertrophy can lead to compression of neighboring organs, a condition known as compressive goiter. This is a rare entity in thyroid pathology, and few studies have been carried out. Many studies have been carried out on thyroid pathologies in general, but few have focused on compressive goiter.
This study aimed to outline the epidemiological, clinical, therapeutic, and evolutionary profile of compressive goiters.
Material and methods: This was a retrospective study from January 2012 to December 2021 of all patients diagnosed and operated on for compressive goiter in the ENT department of FANN. The parameters studied were age, sex, family history of goiter, signs of compression, type of thyroidectomy, histology, and postoperative course.
Results: We identified 65 patients with compressive goiter. The sex ratio was 0.12 (m/f). A family history of goiter was found in 23.07% of cases. A cervicothoracic CT scan was performed in 26.15% of cases.
Total thyroidectomy was performed in all our patients, and we noted 18.47% complications during post-operative follow-up. Anatomopathological data showed a benign goiter in 70.48% of our series.
Conclusion: Compressive goiter is a rare thyroid disease that can be life-threatening because of compression. Total thyroidectomy remains the treatment of choice.

Le malattie cardiovascolari (MCV) sono la principale causa di morte nei paesi occidentali. Diversi studi epidemiologici hanno ipotizzato una disparità di genere nella patogenesi e nella progressione di queste malattie. Ad esempio, le donne sviluppano MCV circa 10 anni dopo gli uomini e, in genere, dopo la menopausa. Tuttavia, considerando che le donne sono spesso escluse dagli studi di ricerca, le differenze di genere nelle MCV rimangono una frontiera per il progresso delle conoscenze. Molto importante è quindi l’identificazione dei fattori di rischio che ci consentono di diagnosticare o prevedere eventi cardiovascolari tenendo conto delle disparità di genere. Lo scopo di questo lavoro è quello di fornire una panoramica delle attuali conoscenze sui determinanti cardiovascolari associati al sesso, allo scopo di migliorare i percorsi clinici diagnostici e prognostici delle malattie cardiovascolari e di sviluppare nuove strategie di prevenzione orientate al genere.
Mapping FRAM to BN through Accimap for system risk assessment: an application to heavy goods vehicle fire risk in road tunnels
Authors: Zhao Yingzhi , Zeng Shengkui , Guo Jianbin , Che Haiyang
Published: February 2025

The Functional Resonance Analysis Method (FRAM) is extensively used to qualitatively analyze the risk of socio-technical systems. To quantitatively assess system risk, previous studies have explored various approaches to integrate FRAM with Bayesian Networks (BN). However, the process of mapping FRAM to BN relies heavily on subjective judgments, often lacking traceability and repeatability. In this paper, a standardized method for mapping FRAM to BN is proposed through introducing Accimap. Firstly, each FRAM’s functional hexagon is transformed into an Accimap, with the six aspects of functions corresponding to Accimap factors. In addition, their internal coupling relationships are obtained by cause and effect investigation in Accimap. Secondly, multiple Accimaps are connected based on the upstream-downstream couplings between functions in FRAM. Through this method, (i) the aspects of FRAM are transformed into Accimap factors and then BN nodes, and (ii) the couplings among the six aspects of functions and across multiple hexagons are converted into BN directed edges.

Published: February 2025

La Dentinogénesis imperfecta (DI) tipo II es una displasia hereditaria rara que afecta la dentina y que se produce durante la etapa de histodiferenciación del desarrollo dentario, resultando en fracturas dentales, especialmente en los posteriores, que a menudo deben extraerse. Esto suele producir una pérdida de la oclusión posterior y de la dimensión vertical oclusal. Además del desgaste y la fractura, los dientes anteriores suelen tener un aspecto poco estético debido al cambio de coloración. Entre los signos clínicos se destacan, además, las coronas globulares, raíces cortas y obliteración de conductos radiculares. Los tratamientos de elección actuales, generalmente, se sugieren para preservar los dientes restantes y la estructura dental, permitiendo un tratamiento preciso y eficaz, con un potencial prometedor en el tratamiento de denticiones afectadas por DI. En este reporte de caso se describe el manejo integral realizado a un paciente masculino de 30 años desde su diagnóstico, tratamiento ortodóntico, protésico-estético, y una intervención implanto-quirúrgica, demostrando la restauración de la oclusión funcional y la estética. Los resultados fueron favorables después de un seguimiento de tres años, contribuyendo al éxito de la rehabilitación del paciente con DI tipo II. Sin embargo, se necesitan investigaciones bien diseñadas para hacer seguimientos a largo plazo y tener un conocimiento basado en evidencia.

Background. Plants exist in close interaction with microorganisms. Bacteria use a special intercellular communication system called "quorum sensing" (QS). This system depends on the density of the bacterial population and coordinates the formation of responses to changing environmental conditions. QS systems play a key role in regulating the bacterial cell's metabolic and physiological processes. Bacterial signaling is perceived by eukaryotes that form a symbiosis with microbial communities. A plant's growth and development, nutrient assimilation, and stress resistance are largely determined by the nature of such interactions. The key group of QS interactions in the population of gram-negative bacteria is acyl homoserine lactones (AHLs), which affect plant growth and development. The effect of AHLs on Angiosperms has been extensively studied. There is also data on the impact of AHLs on moss gametophytes. However, there is no information on the impact of AHLs on Ferns gametophytes and sporophytes. We present here the first study on the effect of hexanoyl homoserine lactone (C6-HHL), a bacterial signaling molecule of the AHLs class, on spore germination and the initial stages of gametophyte development of the homosporous fern Dryopteris filix-mas.

Methods. The dynamic of spore germination was determined on a liquid Knop medium containing 1 μM, 0.1 μM, 0.01 μM and 0.001 μM C6-HHL. Germination was kept and checked on by light microscopy. (Zeiss Axiocam MRc 5, Carl Zeiss).

Results. A moderate stimulating effect (increasing by 6 %) of low C6-HHL concentrations (0.01 μM and 0.001 μM) and an inhibitory effect (decrease by 5.7 %) of higher C6-HHL concentrations (1 μM, 0.1 μM) on spore germination and gametophyte development were established.

Conclusions. The results indicate the sensitivity of Dryopteris filix-mas gametophyte to the influence of bacterial AHL.

English (USA) Qualitative Research on the Labor Trajectories of Highly Educated Latino Immigrants in Florida
Authors: CORREA ANDRES
Published: February 2025

The purpose of this study was to understand the labor trajectories and experiences of Latino immigrant professionals with college degrees who achieved social inclusion after relocating to Florida, United States. In the context of this research, social inclusion was broadly defined as an individual’s participation in a new culture or country. The study employed a phenomenological approach, with data collected through in-depth interviews. These interviews explored both socio-demographic factors and the lived experiences that influenced each participant’s labor trajectory. A total of 18 Latino immigrant professionals, who had lived in the United States for less than ten years and voluntarily participated, were interviewed. The findings suggest that many of these professionals may face underemployment and low wages in Florida. However, their labor trajectories could improve over time if they succeed in validating their foreign educational credentials, enhancing their language proficiency, changing their immigration status, and pursuing further education and professional training in the U.S. Their social integration appears to be limited primarily to interactions within their work environments.

Esta nota presenta una revisión de algunas de las políticas o programas implementados en la región que modifican directamente los procesos de admisión en las instituciones de educación superior (IES), para asegurar el ingreso y la permanencia de grupos históricamente subrepresentados en educación superior. En la literatura estas intervenciones se conocen típicamente como políticas de acción afirmativa (PAA). Nuestra revisión incluye dos tipos de intervención: i) políticas nacionales o que involucran a un grupo amplio de IES y ii) programas en IES con alta matrícula y prestigio. En cada caso describimos su relevancia para las políticas públicas, su origen histórico, su funcionamiento actual y la evidencia disponible sobre su impacto en el perfil de los estudiantes de las IES, en su comportamiento antes del ingreso a la educación superior y en las trayectorias educativas y laborales de los grupos beneficiarios. Nuestros hallazgos revelan el potencial de las PAA para lograr mayor equidad en el acceso y graduación sin comprometer la calidad de la educación entregada por las IES, pero al mismo tiempo plantean una serie de desafíos relacionados con la

Published: February 2025

As práticas produtivas de construção e transformação do meio, em essência, seguem a metodologia de apropriação social da natureza, o que evidencia, em menor ou maior grau, impactos no mesmo, que em sua multiplicidade, demonstram uma falta de interesse do ser humano em extrair do ambiente de forma sustentável, gerando assim, um desequilíbrio em sua relação homem-natureza. Dentro desse contexto se faz necessário abordar um subtema dos impactos na avenida contorno leste com maior ênfase, a identificação de uma microbacia de um afluente do rio Coxipó que foi impactada com a construção da avenida. Este impacto é fruto de um pensamento unitário que desconsidera o todo que é inteiramente integrado e inter relacionado na paisagem.

Published: February 2025

O presente artigo tem como objetivo analisar a cidade de Luanda, no continente africano, e discutir sobre a sua morfologia e desigualdade socioespacial, em função da sua colonização e desenvolvimento. Em vista disso, foi realizado por meio de pesquisas bibliográficas, nas bases de dados: Google Acadêmico, Scielo e periódicos de universidades. Deste modo, a partir dos estudos, foi possível demonstrar que o urbanismo da capital angolana passou por diversas etapas até a guerra civil pós-independência, onde ocorreu uma intensa migração de pessoas para a capital e, assim, um desenfreado e desorganizado crescimento do território urbano da província. Por consequência disso, percebeu-se a criação de bairros informais nas periferias, com pouca infraestrutura, sem acesso à qualidade de moradia e serviços públicos básicos. Além disso, apesar de serem criados instrumentos que deveriam permitir a requalificação destas áreas, como o Plano Diretor Geral Metropolitano de Luanda, estas medidas não são eficientes, portanto, Luanda ainda está longe de oferecer moradias adequadas para a população.

Authors: Hanov Il'yas , Soboleva Ludmila
Published: February 2025

Introduction. Dentists' awareness of HIV-positive patients plays an important role in improving the quality of care for this group of patients.
Objective: to assess the knowledge of practicing dentists about HIV-positive patients taking antiretroviral drugs.
Materials and methods of the study. To achieve the goal of the study, the data obtained from an online survey of 181 doctors of dental specialties were analyzed. Statistical processing of the data was carried out using Microsoft Excel 2023 software.
Results of the study. A large proportion (80.7%) of the surveyed dentists encounter HIV-positive patients at their appointments, 93.9% of the respondents know the difference between HIV and AIDS, but only 59.1% of them have heard/know about HAART drugs. According to 40.3% of the respondents, an HIV-positive patient taking HAART can transmit the virus to a doctor in an emergency situation, while 29.8% answered negatively and 29.8% do not know the answer to this question. More than 24% of dentists believe that HIV infection is transmitted through saliva. When an HIV-positive patient on therapy (HAART) is approached, a large proportion of dentists (50.8%) do not offer them routine procedures. 3.3% of dentists refused to admit an HIV-positive patient. 68.5% of respondents know what viral load is, but only 28.7% of dentists clarify its presence in a patient with HIV. 68.5% of dentists recommend HIV testing to their patients only in cases of atypical SOPS diseases. A patient was refused at the appointment stage or after counseling because of his HIV status in every 10th case.
Conclusion. The vast majority of dentists are poorly informed about HIV infection and the drugs used to reduce viral load. We consider it necessary to recommend planning and conducting separate lecture sessions on HIV infection and the rules of safe reception of patients receiving antiretroviral therapy at universities and courses of additional professional education.

Subject of the study. The article is a literature review dedicated to a personalized approach to medical and preventive measures for chronic periodontitis, considering the diversity of factors contributing to the development and progression of this pathology. The goal of the study is to conduct a descriptive analysis of domestic and foreign literary sources to determine the analysis and structuring of information on the features of modern chronic periodontitis treatment. Methodology. Modern data of Russian and international literature have been studied using scientific library databases such as PubMed, Elibrary, and Cochrane. The literature has been analyzed by sources over the past 9 years based on the following keywords: chronic periodontitis, non-surgical treatment, ultrasound, photodynamic and laser therapy, antimicrobial and antibiotic therapy, phytotherapy. Results. The literature analysis conducted suggests that chronic periodontitis as a highly prevalent condition, is associated with various local and common risk factors. Depending on the risk factors identified, an approach to medical and preventive measures differs and includes both local and general treatments. Conclusions. Many researchers evaluate the effectiveness of using both high-tech and fairly simple, but effective methods of influencing the state of microbiota of periodontal pockets, increasing the activity of factors of local and systemic protection of the patient's organism, means normalizing microcirculation, oxidative stress. The importance of the patient's commitment to cooperation with the attending physician, the need to maintain good oral hygiene and timely visits to the dental clinic for regular preventive sessions in order to prolong the remission phase of chronic periodontitis is emphasized. Thus, the improvement of modern methods of medical and preventive treatment of chronic periodontitis is an important task, while the introduction of products consisting of herbal components and possessing pronounced anti-inflammatory, decongestant and antimicrobial properties, and corresponding methods is especially is especially relevant.

Authors: Risovannaya Olga , Andreasyan Tatev
Published: February 2025

Inflammatory periodontal disease is a worldwide disease of predominantly bacterial etiology characterized by dysregulation of the host inflammatory response. Currently, hyaluronic acid (HA)-based gels are used to treat periodontitis, as well as an innovative gel based on the extracellular matrix, which is a promising material used in regenerative medicine, tissue engineering and other areas of biomedical research. The extracellular matrix is a natural component of tissues that provides structural support to cells and plays a key role in cellular adhesion, proliferation and differentiation. The use of extracellular matrix (ECM)-based gels allows you to create a suitable microenvironment for cells, which promotes their functional activity and tissue regeneration.
The purpose of the article. To study the benefits of extracellular matrix (ECM)-based gels and hyaluronic acid (HA)-based gels in the context of treating inflammatory periodontal disease, and to review the literature.
Materials and methods: For comparative analysis of hydrogels, a detailed analysis of 35 literature sources in the electronic database PubMed, dLibrary for the last 10 years was carried out. The search is not limited to articles published in English, the use of keywords “hyaluronic acid”, “periodontitis” contributed to a successful search. The review included studies assessing the effectiveness and safety of using hydrogels in the treatment of various dental diseases.
Conclusion: Gels based on extracellular matrix and hyaluronic acid as innovative technologies have significant potential for improving the treatment outcomes of various diseases, accelerating the recovery process of patients.
Práticas de leitura orientadas pela BNCC e sua relação com as metafunções da Gramática do Design Visual
Authors: Cordeiro Jessé , Santos Eudes
Published: February 2025

A prática de leitura é intrínseca à comunicação humana, configurando uma das principais ferramentas para o desenvolvimento cognitivo, afetivo, cultural e social dos sujeitos. Tomando como base essa premissa, este trabalho tem como objetivo geral analisar a relação das práticas de leitura orientadas pela BNCC (2017) com as metafunções da Gramática do Design Visual - GDV. Para tanto,  a pesquisa está  ancorada nas discussões de Kress e Van Leeuwen (1996); Silva (2021); Souza (2021);  Lima (2018) e Fernandes (2021). Os dados  analisados demonstram que as metafunções representacional, interacional e composicional podem ser usadas para trabalhar  as seguintes habilidades de leitura, entre outras, presentes na BNCC (2017): identificar o efeito de sentido produzido pelo uso de recursos expressivos gráfico-visuais, inferir e justificar o efeito de humor, ironia e/ou crítica e identificar e analisar efeitos de sentido decorrentes de escolhas e formatação de imagens nos textos multissemióticos presentes em abundância na geração multimidiática, o que pode ser observado na análise que foi realizada  dessas habilidades  a partir dos recursos multissemióticos presentes em narrativas de uma coleção de livro didático de língua portuguesa. O uso das metafunções pode fortalecer, caso sejam trabalhadas pelo professor de maneira eficiente, a potencialização das habilidades de leitura e compreensão de textos por alunos da escolarização básica. Enfim, as análises mostram que as metafunções da GDV são ferramentas capazes de ampliar  as significações da leitura de textos multimodais/multissemióticos.
Reinfección por sífilis gestacional: reporte de caso y revisión sistemática de la literatura
Authors: Villamizar Harold , Vergara Natalia , Martínez-Barreto Daniela , Moreno-Chaparro Jaime , Gaitán-Duarte Hernando
Published: February 2025

Objetivos: presentar un caso de reinfección por sífilis gestacional (SG) y realizar una revisión sistemática de la literatura sobre la frecuencia, el diagnóstico, el tratamiento y el seguimiento de la reinfección.
Materiales y métodos: mujer de 21 años, inmigrante, quien es hospitalizada por preeclamsia y vaginosis bacteriana. Refiere que fue diagnosticada y tratada por SG en el primer trimestre, con posterior disminución de los títulos de Venereal Disease Research Laboratory (VDRL), y nueva elevación de los mismos detectada a la semana 39. Se hace el diagnóstico de reinfección por sífilis y recibe nuevamente tratamiento con penicilina benzatínica. El recién nacido presenta VDRL positivo, dilución (1:2), sin signos clínicos ni secuelas de infección por Treponema Pallidum; se hace diagnóstico de Sífilis Congénita (SC) y recibió tratamiento con penicilina G cristalina intravenosa, con evolución satisfactoria. Se realizó una revisión sistemática de la literatura desde el inicio de registro de cada base de datos hasta noviembre de 2023, en Medline (PubMed), Embase, Scopus, Web of Science y Lilacs. Se seleccionaron reportes de caso, series de casos y cohortes de mujeres gestantes con reinfección por sífilis. Dos autores seleccionaron los estudios y extrajeron los datos de manera independiente. Se describen las características del estudio, la población, las características del diagnóstico, el tratamiento de la SG y la frecuencia de casos de reinfección. Análisis descriptivo.
Resultados: se identificaron 208 títulos potencialmente relevantes, de los cuales 12 fueron evaluados en texto completo. Finalmente, se incluyeron seis artículos. En total, 85 mujeres presentaron una reinfección por sífilis durante la gestación (3,8 %). La incidencia de reinfección por sífilis durante el embarazo varía entre el 1,5 y 7,3 %. El diagnóstico se realizó en mayor medida con pruebas no treponémicas (83,3 %). La información disponible respecto al tratamiento de la gestante con reinfección, el seguimiento, el tratamiento del compañero y los resultados perinatales es limitada.
Conclusiones: la vigilancia activa e individual de los casos de SG tratada es importante porque permite no solo identificar la reinfección, sino también garantizar el tratamiento de los compañeros sexuales para prevenirla. Se requieren estudios prospectivos para evaluar la magnitud de este problema, sus consecuencias perinatales y la posible resistencia a la penicilina.

Authors: Basar Yeliz , Seker Mustafa Ege , Guven Koray
Published: February 2025

Objective: To compare radiation doses associated with transradial access (TRA) and transfemoral access (TFA) in transarterial chemoembolization (TACE) and transarterial radioembolization (TARE) procedures for hepatic cancers.
Methods: This retrospective, single-center study analyzed 119 patients who underwent TACE or TARE between October 2016 and October 2024. Radiation dose parameters were compared between TRA and TFA groups, including fluoroscopy time, fluoroscopy and fluoroscopy-digital radiography combined dose-area product (DAP), and total air kerma (AK). Statistical analyses were performed using the Mann-Whitney U test and Chi-squared test.
Results: TRA was associated with significantly higher radiation exposure compared to TFA, including increased fluoroscopy time (median: 15.2 vs. 8.9 seconds, P<0.001), fluoroscopy DAP (median: 84.4 vs. 45.2, P<0.001), fluoroscopy-digital radiography combined DAP (median: 246 vs. 156.5, P=0.003), and AK (median: 959 vs. 612.9, P=0.001). No significant differences were observed in patient demographics, tumor localization, or treatment approach between the groups.
Conclusions: TRA is associated with higher radiation exposure compared to TFA in TACE and TARE procedures. While TRA offers procedural benefits, further research is needed to optimize techniques and reduce radiation risks, particularly in interventional radiology.
