Published: June 2024

Este artigo é resultado de um percurso de estudos de um grupo de pesquisa sobre pesquisa-ação na Pedagogia do Esporte, cujo objetivo foi realizar uma revisão sistemática da produção científica sobre os métodos de ensino dos esportes, realizadas por meio de uma pesquisa-ação. Para isso realizamos uma busca na base de dados EBSCO, por ser uma base que contempla artigos da Pedagogia do Esporte em esfera internacional. Foram encontrados oito artigos, os quais foram analisados por meio de uma análise temática reflexiva e chegamos nas seguintes categorias de análise: (a) Local da pesquisa; (b) Tempo de Pesquisa; (c) Cenários; (d) Produção das informações; (e) Instrumentos; (f) Abordagem pedagógica utilizada; (g) Tipos de Pesquisa-ação.  Após a análise, percebemos que existem diferentes modos de se fazer pesquisa-ação na Pedagogia do Esporte. Basicamente as pesquisas são paraalguém (colaborativa) e ou sobre alguém (estratégica), ou seja: no primeiro caso o processo de ensino é pensado para um determinado grupo e existe diálogo com quem participa da pesquisa. Já no segundo grupo (sobre) as pesquisas foram realizadas por meio de uma intervenção de ensino, na qual quem participa não contribui.  Outro aspecto marcante da análise foi a ausência de pesquisa que investiguem com os(as) participantes (pesquisa ação crítica).
Foucault, as artes visuais, o ensino de arte
Authors: Sabino Kelly , Aquino Julio Groppa
Published: June 2024

Com base em algumas teorizações de Michel Foucault sobre as artes visuais, o presente artigo tenciona prospectar possíveis contribuições ao ensino da arte. Ao rastrear os escritos do pensador francês e de alguns comentadores seus sobre a temática, destaca-se a questão da relação disjuntiva entre imagem, palavra e representação. Sabe-se que a imagem é uma espécie de pedra de toque do ensino da arte desde pelo menos a criação das Academias de Belas-Artes e, no caso do ensino da arte no Brasil, figurou de maneira sistematizada a partir do final da década de 1980, com a chamada Proposta Triangular. Mais recentemente, por meio das abordagens intercultural, multiculturalista e da cultura visual, atesta-se o pleito da expansão da noção de imagem no ensino das artes visuais. Propor uma mirada, sob a ótica foucaultiana, sobre a relação não complementar entre imagem e palavra permite, ao fim e ao cabo, que a temporalidade das imagens desponte, alterando a natureza do que é visto e de quem o vê, no sentido contrário ao da suposição representacional de um testemunho fiel ou ainda de um reconhecimento classificatório universal. Daí que, na companhia de Didi-Huberman, é possível concluir que ver as imagens, no tempo, é estar diante do arquivo do mundo. Em suma, é nossa própria experiência que ali ganha força.
Uso do método educacional colaborativo para AEC apoiado por manufatura aditiva
Authors: Carboni Márcio Henrique de Sousa , Scheer Sérgio
Published: June 2024

Inovação tecnológica na indústria da construção civil é tema recorrente. Para tanto, é importante que novas tecnologias sejam exploradas nos centros de capacitação de profissionais da Arquitetura, Engenharia e Construção (AEC). Entre várias tecnologias com grande potencial disruptivo, a Manufatura Aditiva (Additive Manufacturing - AM) se destaca. Somado a isso, nota-se a necessidade de experiências educacionais mais interdisciplinares durante a graduação, mais próximas da realidade encontrada no mercado de trabalho. Baseado nesse panorama, desenvolveu-se através do Design Science Research o MECA-AM - “Método Educacional Colaborativo para AEC apoiado pelo uso da Manufatura Aditiva”, que busca o aprendizado interdisciplinar de alunos de Arquitetura e Urbanismo, Engenharia Civil e Expressão Gráfica através de atividades com abordagem PBL (Project-based Learning ou Aprendizado baseado em projetos) que priorizam o aprendizado colaborativo e utilizam a Manufatura Aditiva como uma ferramenta de estímulo a integração. Neste trabalho, apresentam-se duas experiências de aplicação deste método realizadas em 2021 e 2022, em workshops de 5 semanas, para o ensino da temática “Detalhes Arquitetônicos Construtivos”. A percepção dos alunos sobre o curso foi avaliada de maneira objetiva e subjetiva através de questionário aplicado que revelou alto índice de aceitação e avaliação positiva. Também enalteceu a importância de os alunos de Expressão Gráfica participarem de grupos multidisciplinares AEC, uma vez que suas habilidades em modelagem virtual e manuseio de equipamentos de impressão 3D colaboraram para o sucesso das atividades propostas, já que os estudantes de Arquitetura e Engenharia Civil geralmente não possuem exposição quanto a esses conteúdos em seus cursos de graduação atuais.

Published: June 2024

Electrochemical nitrogen reduction reaction (ENRR) has emerged as a potential alternative to the conventional Haber-Bosch process for ammonia production. However, ENRR technology is still restricted by the limited Faradaic efficiency due to the hard-to-break N-N triple bond. Herein, inspired by the biomimetic catalyst, we developed a Fe-modulated MoS2 catalyst (named Fe@MoS2) as an efficient ENRR catalyst. Raman spectra, coupled with the X-ray absorption spectroscopy, demonstrate the introduction of Fe into the MoS2 lattice and achieve partial 2H to 1T phase conversion. The presence of S-vacancies on MoS2 substrates was observed on scanning transmission electron microscopy images. Operando infrared absorption spectroscopy confirms that the constructed catalytic site significantly reduces barriers to nitrogen activation. The synthesized Fe@MoS2, with its superior geometric and electronic structures, exhibits a remarkable Faradaic efficiency of 19.7 ± 5.5% at -0.2 V vs. Reversible Hydrogen Electrode and a high yield rate of 20.2 ± 5.3 μg h-1 mg-1 at -0.8 V vs. Reversible Hydrogen Electrode. Therefore, this work provides a fresh direction for designing novel catalysts, eventually boosting the nitrogen reduction reaction kinetics and accelerating the ENRR application.

The article contains a description of the development process of Local Wellbeing Index (LWBI) by the Rating Lab research laboratory for urban and rural settlements. The first part of the text is dedicated to building a theoretical model based on publications from sociological and psychological fields, which studied one’s wellbeing in settlements The models and studies of urban research, psychological and emotional parameters of wellbeing of residents of settlements, sustainability of well-being, provision of basic needs in the settlement and cities as zoned spaces were used a basis for the study. The following part depicts the results of constructing an empirical model for LWBI measurements built based on conducting of two waves of testing surveys on small-scale samples. The final model consists of 22 indicators which are distributed across five dimensions – emotional perception of a settlement, the level of economic opportunities, the level of orderliness of a settlement, the level of education and medicine, and the level of civil security in a settlement. The third stage of our study covered the measurement of LWBI in Ukrainian settlements based on the results of a national representative survey (n=8572). The retrieved data was used to validate the methodology we developed according to the parameters of the model’s reliability, criterion, and construct validity. Such methods as correlation analysis, confirmatory factor analysis (CFA) and the checks of data’s applicability to the data were applied to achieve the results. Overall, we have managed to confirm the validity of our measurement tool and its suitability for research projects aimed at measuring the levels of local wellbeing in urban and rural settlements.
МЕТОДОЛОГІЇ АНАЛІЗУ ЗОБРАЖЕНЬ ДЛЯ ДІАГНОСТИЧНИХ ЗАСТОСУВАНЬ (ОГЛЯД)
Authors: Давидович Ілля , Бабенко Віталій
Published: June 2024

Медична візуалізація є невіддільною частиною сучасної клінічної практики та досліджень у галузі охорони здоров'я, слугуючи наріжним каменем у сфері діагностичних процедур та забезпечуючи критично важливу основу для вибору методів лікування, спрямованих на підвищення рівня виживання пацієнтів. Серед різних підходів, доступних для обробки та аналізу медичних зображень, нейронні мережі отримали найбільше визнання, головним чином завдяки їхньої здатності швидко обробляти знімки будь-якої модальності, забезпечуючи при цьому діагностичний аналіз з високою якістю. Однак широкому впровадженню таких технологій часто перешкоджають значні фінансові витрати та труднощі для медичних працівників при розшифровуванні результатів. Нейронні мережі, які є непрозорими у своїх процесах прийняття рішень, породжують дилему «чорної скриньки», хоча при постановці діагнозу остаточне рішення приймає лікар, а не мережа. Таким чином, існує потреба в розробці методологічної бази для обробки та аналізу медичних зображень, здатної забезпечити надійну підтримку прийняття діагностичних рішень. Дана наукова робота присвячена охопленню методологій порівняння зображень. Це фундаментальна процедура, яка дозволяє ідентифікувати невідповідності між зображеннями, не покладаючись на нейронні мережі або інші парадигми машинного навчання. Для досягнення мети було розглянуто низку методологій порівняння зображень, кожна з яких містить свій власний набір сильних і слабких сторін. Отриманий в результаті порівняльний аналіз дозволить дослідникам робити виважений вибір відповідно до індивідуальних потреб і вимог. Таким чином, дана праця робить значний внесок у постійний розвиток медичної візуалізації, тим самим сприяючи покращенню догляду за пацієнтами та підвищенню точності діагностики в цій галузі.
ЗАСТОСУВАННЯ НЕЙРОННОЇ МЕРЕЖІ ДЛЯ КЕРУВАННЯ РУХАМИ ПАЛЬЦІВ БІОПРОТЕЗУ
Authors: Гнєтнєв Костянтин , Шликов Владислав
Published: June 2024

Дана робота присвячена розробці системи керування біонічного протезу руки, яка використовує нейрону мережу для управління рухами пальців протезів, шляхом навчання нейронної мережі у процесі зчитування електроміографічних (ЕМГ) сигналів зі здорової руки та їх синхронізації з ЕМГ-сигналами у культі пацієнта. Такий підхід дає змогу пацієнтам швидше звикнути до протеза і ефективніше керувати ним під час використання. Крім того, застосування дешевих і вітчизняних складників дозволить зробити такі протези більш доступними для пацієнтів. Макетний зразок системи керування протезом має вигляд простого захоплюючого механізму, для керування яким використано один датчик, що приймає сигнали з відповідного м’язу здорової руки. Наприклад, для відтворення рухів згинання вказівного пальця обрано поверхневий м’яз згинання пальців (musculus flexor digitorum superficialis) як м’яз поверхневого шару м’язів передпліччя, який знаходиться в оточенні м’язів синергістів. Модель нейронної мереж має два прихованих шари та простий класифікатор: два прихованих шари по 200 нейронів, вхідний шар на 3 нейрони, і  вихідний шар на 1 нейрон. Максимальне відхилення від точності 1.000 під час навчання нейронної мережі складає 0.013, що обумовлює достовірний результат за 100 епох. Після того, як нейронна мережа робить передбачення на основі рухів здорової руки, система керування протезом на основі мікроконтролера Arduino подає класифіковану подію на виконуючий двигун у вигляді коду: 0 – розкриття кисті, 1 – стискання кисті. Таким чином, у розробленій системі керування біонічним протезом руки увага зосереджена на забезпеченні легкого та швидкого процесу реабілітації та використання протезу
ОЦІНКА ВПЛИВУ ОРТОТРОПІЇ КІСТКОВОЇ ТКАНИНИ НА НАПРУЖЕНО-ДЕФОРМОВАНИЙ СТАН ЧИСЕЛЬНОЇ МОДЕЛІ ОСТЕОСИНТЕЗУ ВІДКРИВАЮЧОЇ КОРИГУЮЧОЇ ОСТЕОТОМІЇ ВЕЛИКОЇ ГОМІЛКОВОЇ КІСТКИ

Published: June 2024

Проблематика. Одним з ушкоджень нижньої кінцівки є О-подібна або Х-подібна деформація в колінному суглобі. Для лікування цього захворювання успішно використовують коригуючу остеотомію великої гомілкової кістки. Суть остеотомії полягає у перетині кістки з метою вирівнювання її осі та подальшою фіксацією в заданому положенні. За рахунок сучасних програмних комплексів можна оцінити ефективність запропонованої конструкції фіксатора. У більшості робіт, пов’язаних із вивченням напружено-деформованого стану систем «кістка – фіксатор», кісткова тканина розглядається як однорідне, ізотропне, пружне середовище. Очевидно, що таке припущення може призвести до неточності при оцінці результатів зазначеного дослідження.
Мета. Дослідити вплив ортотропії механічних властивостей кісткової тканини на напружено-деформівний стан системи «кістка-фіксатор» чисельної моделі остеосинтезу високої відкриваючої коригуючої остеотомії великої гомілкової кістки.
Методика реалізації. Дослідження виконувалось в спеціалізованому програмному комплексі заснованому на методі скінчених елементів. Для розв’язку поставленої задачі були побудовані дві тривимірні моделі зазначеного остеосинтезу. Моделювалися два випадки механічних властивостей матеріалу кістки: ізотропним та ортотропним середовищем.
Результати. В результаті дослідження отримано розподіл напружень в елементах системи «кістка – пластина-фіксатор». Для виконання оцінки впливу ортотропії механічних властивостей обрано еквівалентні напруження за Мізесом. Кількісні показники напружень в ізотропній та ортотропній моделях відрізнялись, проте якісні картини їх розподілу були подібними.
Висновки. При зміні ізотропної моделі кісткової тканини на ортотропну відбулась зміна напруженого стану в системі «кістка-фіксатор» в більшу сторону. Найбільші і найменші зміни відбулись в фіксуючих гвинтах (8-58 %), в пластині і кістці ці зміни склали 15-20 %. Враховуючи, що при використанні ізотропних моделей кісткової тканини в розрахунках отримані величини напружень можуть бути значно занижені, необхідно це явище враховувати при аналізі результатів

Серцево-легенева реанімація є однією з найважливіших процедур першої допомоги. Тренінги та семінари з надання першої допомоги та тактичної медицини, у рамках яких вивчають також проведення серцево-легеневої реанімації, набирають популярність у суспільстві. Ефективність таких тренінгів та, надалі, якість проведення серцево-легеневої реанімації постраждалим у критичних ситуаціях, залежить від забезпечення якісного зворотного зв’язку при виконанні процедури. У даній статті запропоновано прототип системи зворотного зв’язку для надання серцево-легеневої реанімації, у складі якої є пристрій, що виконує оцінку виконуваної процедури та програмне забезпечення, яке виконує візуалізацію усіх рухів під час компресій грудної клітини. Використовуючи дані акселерометра, пристрій обраховує силу, глибину та частоту натискань на грудну клітину при виконанні серцево-легеневої реанімації. Вбудоване програмне забезпечення для пристрою було розроблено у рамках операційної системи реального часу для мікроконтролерів FreeRTOS, що гарантує контрольовану та своєчасну обробку усіх дій що виконуються над системою зворотного зв’язку. У статті описано розробку пристрою на основі MEMS акселерометру та здійснення апробації пристрою у реальних умовах із залученням медичного фахівця та тренувального манекену. Створений пристрій, дані з якого візуалізуються за допомогою програмного забезпечення, показав результат тестування у 98.72% правильно зафіксованих компресій грудної клітини. Використання цього пристрою зворотного зв'язку у поєднанні з програмою візуалізації покращить результати проведення тренінгів першої медичної допомоги та сприятиме підвищенню якості надання медичної допомоги в екстрених ситуаціях

Authors: Adeoye Olumuyiwa Oluseun , Olubiyi Timilehin Olasoji
Published: June 2024

Purpose – This study aims to identify the factors influencing entrepreneurial intentions among private university students in South-West Nigeria, and to determine their significance.Methodology – The study population consisted of final-year students from the Faculty/College of Business and Social Sciences across 11 selected private universities in South-West, Nigeria, offering entrepreneurship courses. This study used a sample of 623 students. Data were collected using a self-developed instrument with a reliability coefficient of 0.847 for student-related factors and 0.80 a entrepreneurial intentions. The Relative Significance Index (RSI) and multiple regression analyses were used.Findings – The results revealed that most students perceived several factors as influential on entrepreneurial intention. The key factors were students’ personal factors, family history, technical abilities, and parental attitude. Despite recognizing these influences, many students lacked the skills to solve challenges and effectively utilized technical literature and other information sources. Multiple regression analysis indicated that student parental attitude, student personal factors, and technical abilities significantly influenced entrepreneurial intentions.Implications – This study highlights the importance of enhancing students' personal factors, technical abilities, and parental attitudes to foster entrepreneurial intention. Educational institutions and policymakers should focus on these areas to cultivate an entrepreneurial mindset among students.Originality – This study provides empirical evidence on the determinants of entrepreneurial intentions among private university students in Nigeria, contributing to a broader understanding of how personal, familial, and technical factors shape entrepreneurial aspirations.
A Compact, Low-Cost and Low-Power Turbidity Sensor for Continuous In-Situ Stormwater Monitoring
Authors: Wang Miao , Shi Baiqian , Catsamas Stephen , Kolotelo Peter , McCarthy David
Published: June 2024

Turbidity stands as a crucial indicator for assessing water quality, and while turbidity sensors exist their high cost prohibit their extensive use. In this paper, we introduce an innovative turbidity sensor, and it is the first low-cost turbidity sensor which is designed specifically for long-term stormwater in-field monitoring. Its low cost ($23.50 USD), enables the implementation of high spatial resolution monitoring schemes. The sensor design is available under open hardware and open-source licences, and the 3D-printed sensor housing is free to modify based on different monitoring purposes and ambient conditions. The sensor was tested both in the laboratory and in the field. The laboratory results show a strong linear relationship (R2 > 0.99) between the sensor readings and the commercial hand-held turbidimeter (Thermo Scientific AQ4500) results of the solution. In the field, the low-cost sensor measurements were statistically significantly correlated (p < 0.01) to a standard high-cost commercial turbidity sensor (GreenSpan TS-1000). Biofouling and drifting issues were also analysed after the sensors were deployed in the field for more than 6 months, showing both biofouling and drift occur during monitoring. Nonetheless, in terms of maintenance requirements, the low-cost sensor exhibited similar needs compared to the Green-Span sensor.
Photonic and phononic modes in acoustoplasmonic toroidal nanopropellers
Authors: Castillo López de Larrinzar Beatriz , García Jorge M. , Lanzillotti-Kimura Norberto Daniel , García-Martín Antonio
Published: June 2024

Non-conventional resonances, both acoustic and photonic, are found in metallic particles with a toroidal nanopropeller geometry that is generated by sweeping a three-lobed 2D-shape along a spiral with twisting angle, α. For both optical and acoustic cases, the spectral location of resonances experiences a red-shift as a function of α. We demonstrate that the optical case can be understood as a natural evolution of resonances as the spiral length of the toroidal nanopropeller increases with α, implying a huge helicity dependent absorption cross section. In the case of acoustic response, two red-shifting breathing modes are identified. Additionally, even a small α allows the appearance of new low-frequency resonances, whose spectral dispersion depends on a competition between length of the generative spiral and the pitch of the toroidal nanopropeller.
Influence of Ethical Supply Chain Practices on Brand Equity: A Qualitative Study of Consumer Perspectives
Authors: Holloway Samuel
Published: June 2024

This qualitative study explores the influence of ethical supply chain practices on brand equity from the perspective of consumers. In-depth interviews were conducted with 30 participants to examine their attitudes, perceptions, and behaviors towards brands that emphasize ethical considerations in their supply chain operations. Thematic analysis revealed several key findings. Transparency and authenticity emerged as critical factors influencing consumer trust and perceptions of brand integrity. Participants valued brands that communicated clearly and honestly about their ethical sourcing practices, viewing transparency as indicative of reliability and ethical commitment. Ethical considerations significantly influenced consumer purchase decisions, with participants emphasizing the importance of factors such as fair labor practices, environmental sustainability, and responsible sourcing in shaping their perceptions of product quality and brand value. Brands that integrated these ethical principles into their supply chain management were perceived as offering higher-quality products, which enhanced consumer willingness to pay a premium and bolstered brand reputation. The study also highlighted varying levels of consumer awareness and engagement with ethical supply chain practices, underscoring the importance of effective communication and consumer education. Ethical supply chain practices were found to foster brand loyalty and trust, with brands perceived as ethical and socially responsible enjoying stronger consumer relationships and loyalty. Overall, the findings suggest that ethical supply chain practices play a crucial role in enhancing brand equity by aligning business operations with consumer values and expectations. The study contributes to existing literature by providing empirical insights into the mechanisms through which ethical considerations influence consumer perceptions and behaviors towards brands.

Time Series Forecasting with Many Predictors
Authors: Huang Shuo-Chieh , Tsay Ruey S
Published: June 2024

We propose a novel approach for time series forecasting with many predictors, referred to as the GO-sdPCA, in this paper. The approach employs a variable selection method known as the group orthogonal greedy algorithm and the high-dimensional Akaike information criterion to mitigate the impact of irrelevant predictors. Moreover, a novel technique, called peeling, is used to boost the variable selection procedure so that many factor-relevant predictors can be included in prediction. Finally, the supervised dynamic principal component analysis (sdPCA) method is adopted to account for the dynamic information in factor recovery. In simulation studies, we found that the proposed method adapts well to unknown degrees of sparsity and factor strength, which results in good performance even when the number of relevant predictors is large compared to the sample size. Applying to economic and environmental studies, the proposed method consistently performs well compared to some commonly used benchmarks in one-step-ahead out-sample forecasts.
Vehicle in Water Rescue: Will Laminated Glass Be the Death of Us?
Authors: Glassey Steve
Published: June 2024

The automotive industry is increasingly adopting laminated glass in side and rear windows to comply with safety standards aimed at reducing ejection injuries. However, this trend may have unintended consequences for occupant rescue and escape in submerged vehicle incidents. As more vehicles incorporate laminated glass, concerns arise that they could become "glass coffins" in water, making it more difficult for occupants to exit or be rescued. The use of laminated glass is driven by Federal Motor Vehicle Safety Standard 226 (FMVSS 226) for ejection mitigation, but it does not address the risk of vehicle submersion and occupant drowning. Drowning accounts for a substantial portion of vehicle-related fatalities. As the adoption of laminated glass grows, there is a need for drowning prevention measures, such as automatic window opening systems, to mitigate the risk of vehicles becoming "glass coffins" in water. A comprehensive approach addressing both ejection and submersion dangers is necessary to maximize occupant protection and save lives.

Published: June 2024

Despite advances in our knowledge of systemic lupus erythematosus (SLE) has increased over time, there are still many challenges in deciphering the precise mechanisms involved in the development and progression of the disease. Recent evidence has raised questions about the effectiveness of the programmed cell death protein 1 (PD-1) in suppressing autoreactive CD4+ T cells during the autoimmune response. Research has ventured into investigate the potential impact of PD-1 on various CD4+ T cell subpopulations, including T follicular helper (Tfh) cells, circulating Tfh (cTfh) cells, and T peripheral helper (Tph) cells, all of which exhibit substantial PD-1 expression and have been closely related with several autoimmune disorders including SLE. This review aims to highlight the complex role of PD-1 in autoimmunity and emphasizes the imperative for further research to elucidate its functions during autoreactive T-cell response. Additionally, we address the potential of PD-1 or its ligands as a possible therapeutic target in SLE.
Erroneous Applications of Fractional Calculus: The Catenary as a Prototype
Authors: Becerra-Guzmán Gerardo , Villa-Morales José
Published: June 2024

In this work, we study the equation of the catenary curve in the context of the Caputo derivative. We solve this equation and compare the solution with real physical models. From the experiments, we find that the best approximation is achieved in the classical case. Therefore, introducing a fractional parameter arbitrarily can be detrimental. However, we observe that when adding a certain weight to the chain, fractional calculus produces better results than classical calculus for modeling the minimum height.

Published: June 2024

The injury causes resistance in human gastric cancer (GC). This Adverse Outcome Pathway (AOP) entitled “Increases in cellular reactive oxygen species (ROS) and chronic ROS leading to human treatment-resistant gastric cancer (GC)” consists of molecular initiating event (MIE) as “Increases in cellular ROS” and “Chronic ROS”, followed by series of key events (KEs); “porcupine-induced Wnt secretion and Wnt signaling activation”, “beta-catenin activation”, “epithelial-mesenchymal transition (EMT), and adverse outcome (AO) as “human treatment-resistant GC” in the sequence. ROS has multiple roles in disease such as development and progression of cancer, or apoptotic induction causing anti-tumor effects. In this AOP, we focus on the role of sustained levels of chronic ROS to induce the therapy-resistance in human GC. EMT, which is cellular phenotypic change from epithelial to mesenchymal-like features, demonstrates cancer stem cell (CSC)-like characteristics in human GC. EMT is induced by Wnt/beta-catenin signaling, providing the rationale to have Wnt secretion and beta-catenin activation as KEs in the AOP.
Stress-Related Chronic Fatigue Syndrome: A Case Report with Positive Response to Alpha-Methyl-P-Tyrosine (AMPT) Treatment
Authors: Ljungström Maria , Oltra Elisa , Pardo Marta
Published: June 2024

Alpha-methyl-p-tyrosine (AMPT; also referred as metyrosine) is an approved medication for the treatment of pheochromocytoma. As a tyrosine hydroxylase inhibitor AMPT may be a potential candidate for the treatment of diseases involving catecholamine alterations. However, only small-scale clinical trials have tested AMPT repurposing in few other illnesses. Chronic fatigue syndrome (CFS) is an heterogenous disorder with genetically associated vulnerability of catecholamine metabolism (e.g. catechol O-methyltransferase polymorphisms) holding an important impact of environmental factors. The current case report compiles genetic and longitudinal biochemical data for over a year follow-up of one patient sequentially diagnosed with sustained overstress, neurasthenia, CFS, and POTS (postural orthostatic tachycardia syndrome) over a 10-year period, and reports patient’s symptom improvement in response to low-medium doses of AMPT.

Approximately more than 120 transthyretin mutations are known whose variation in clinical presentation is heterogeneous, as the course of disease onset depends on genetic variation and level of penetrance. It is little known in Ecuador, and some of the reported cases; suggest to the family tree analysis that they come from a province that is possibly considered endemic. The main objective is to carry out a descriptive cross-sectional analysis on the presentation of transthyretin amyloidosis in families carrying the p.Ser43Asn gene from the index case identified.

Published: June 2024

Lahpet-ye-hsain, known as a “tea shop” or teahouse, is where the people of Myanmar conduct their daily social activities besides its economic orientation. They are private establishments and informal gathering places serving tea and food at different times of the day for various clients. They can be small snacks, large open-aired, or covered restaurants with extensive menus. Patrons sit around small square tables on footstools. A diverse range of characters goes to tea shops. They have a reputation for welcoming people from all backgrounds and walks of life, but the role of women is hardly seen and unclear. They provide a space for men to share a cup of tea and food and exchange ideas, opinions, problems, hopes, and aspirations. They provide not only space but also to get ‘good taste and cheap food.’ A cup of tea at a tea shop is an opportunity to share knowledge amongst old and new friends. Such shops are abundant over the country. This paper examines the social, political, and economic role of these ubiquitous features of Myanmar society. The barriers to women's participation and inroads in some locales are discussed.

Case:

A 64-year-old man presented with a 3-year history of right wrist pain and swelling 33 years after a silicone scaphoid arthroplasty for chronic scaphoid nonunion. Radiographs demonstrated a deformed scaphoid implant, carpal and distal radius cysts, and mild carpal collapse. He elected to undergo a wrist arthrodesis with a dorsal fusion plate after failing conservative management.

Conclusion:

Although carpal bone silicone implant arthroplasties of the wrist have long been abandoned, our patient was pain free and fully functional for 3 decades. He was pleased to undergo serial examinations with radiographs for 30 years without any therapeutic intervention.

Authors: Seeli D.jeni Jeba , Thanammal K.K.
Published: June 2024

In the medical field, disease diagnosis through cloud computing is a promising technology to focus more on patient care. It offers benefits for both patients and doctors. We aimed to develop a cloud based classification method for patients with brain haemorrhage in rural (or) remote areas. The detection of brain haemorrhage is critical for neurological diagnosis and treatment. Although deep learning models have shown promise in medical image analysis, predicting brain haemorrhage remains challenging due to its complexity and variability. To address this, we propose an ensemble approach for detection of Intracranial Haemorrhage diagnosis using cloud computing. Cloud services enable data to be stored on remote servers and then be accessed via the Internet. The user does not need to be in a specific location to access it, which allows the user to work remotely. The ensemble comprises diverse deep learning models (ResNet50, VGG16, and DenseNet121) with Global Average Pooling 2D layers, benefiting from the cloud's computational resources for efficient training. Each model brings unique strengths, enabling us to capture a wider range of data patterns and improve prediction accuracy. Data pre-processing involves dividing the dataset into training and validation sets. The base models are trained on the training data, and hyper parameters are fine-tuned via cross-validation on the validation set. The stacking and blending techniques combine base model predictions. Stacking uses validation predictions to train a meta-model that intelligently combines individual predictions, while blending directly averages predictions for a simpler ensemble. To overcome the Challenges of privacy preserving, data protection, improve the performance and fast diagnosis, the proposed work is also deployed in a cloud based framework. Performance evaluation employs standard metrics on a separate test set. Results show that the ensemble approach significantly enhances Intracranial Haemorrhage Prediction, improving clinical decision-making for neurological emergencies and fast diagnosis. Our approach incorporates strategies to handle class imbalance, such as using suitable loss functions and data augmentation during training.

The focus of this paper is to present an innovative approach to classify land cover, with specific emphasis on Land Use, Land-Use Change and Forestry (LULUCF) monitoring. LULUCF is a sector in greenhouse gas inventory that tracks changes in greenhouse gas levels in the atmosphere due to land use and land-use change. In this study, we employed Deep Learning classifiers and Random Forest to classify land cover/land use in Czechia, adhering to LULUCF regulations. We evaluated the effectiveness of 2D and 3D Convolutions in Convolutional Neural Networks, with varying filter sizes and training methods, alongside the use of Random Forest classifier. We used Sentinel-2 bands with 10 m and 20 m spatial resolution, NDVI, NDVI variance, and SRTM altitude data to create input paths of 5×5 pixels. The results indicate that the 3D model trained with classical training and 3×3-pixel filters achieved the best F1 Score of 0.84. One significant advantage of using convolutional neural networks is their ability to include information from a pixel’s neighbourhood in the classification process, in contrast to solely considering the pixel itself.

Authors: TRIVEDI RASHMI , Upadhyay Tarun Kumar , Prabhakar Pranav Kumar
Published: June 2024

Background
Prostate cancer remains a challenge in healthcare, being the second most common male cancer demanding innovative therapeutic approaches and treatment techniques. This study integrates in silico and in vitro methods for the investigation of the potential anticancer effects of quercetin-loaded and alginate-sealed β-Glucan particles derived from mushroom Agaricus bisporus and yeast against the DU145 cell line.
Methods
Prostate cancer-related genes were identified from DisGeNET and GeneCards databases, followed by target prioritization using Swiss Target Prediction software. Venny 2.1 was used for the determination of common targets between β-Glucan, Quercetin, and prostate cancer and PPI network was constructed using STRING database. CB dock online server was used for molecular docking and DU145, RAW264.7 cell lines were used for the determination of cytotoxicity against prostate cancer and healthy cells.
Results
Molecular docking revealed that quercetin has superior binding affinity compared to β-Glucan with selected prostate cancer-related targets. In vitro evaluation using MTT assays demonstrated the cytotoxic effects of quercetin-loaded and alginate-sealed particles against DU145 prostate cancer cells. Apoptosis induction, ROS generation, and lysosomal pH alterations underscore the potential of quercetin-loaded and alginate-sealed β-Glucan particles as promising therapeutic agents for prostate cancer.
Conclusions
Our study showed systematic analyses of the effect of hollow β-Glucan particles, Quercetin, and Quercetin alginate sealed particles against DU145 cells and found that formulation exhibits superior anticancer activity against prostate cancer cell line. Quercetin-loaded alginate-sealed particles showed very little cytotoxicity against healthy cell line RAW264.7. Future studies focusing on preclinical validation, pharmacokinetic profiling, and clinical trials to assess translational potential and optimize therapeutic strategies can help get impactful findings.

Published: June 2024

Background: There are several risk factors for early allograft dysfunction (EAD) after donation after citizen death (DCD) liver transplantation. This study explored whether elevated donor’s seral creatinine increases the risk of EAD after DCD liver transplantation.
Materials and Methods: The study enrolled 224 primary adult DCD liver transplantation recipients. Univariate and multivariate logistic regression analyses were performed, and receiver operating characteristic curves were constructed. Perioperative clinical and laboratory variables were assessed for their association with the prevalence of EAD using the inverse probability of treatment weighting (IPTW) and 1:3 propensity score (PS) matching (Group A, n=53; Group B, n=124) analysis.
Results: Forty-eight recipients (21.4%) developed EAD. All cases were divided into two groups (Group 1 [donor’s seral creatinine > 170μmol/L, n = 55] and Group 2 [donor’s seral creatinine ≤ 170μmol/L, n = 169]). Multivariate logistic regression analyses revealed that the donor’s age >60 years old (OR 5.927, 95CI% 2.144-16.387, p=0.001), BMI >24 (OR 2.818, 95CI% 1.359-5.845, p=0.005), with hypertension (OR 2.308, 95%CI 1.086-4.902, p=0.030), ICU stay >7 days (OR 3.369, 95% CI 1.449-7.832, p=0.005), and seral creatinine >170 μmol/L (OR 2.841, 95%CI 1.309-6.164, p=0.008) were independent risk factors for EAD. Moreover, the donor’s seral creatine >170 μmol/L was associated with incidence of EAD after adjusting for IPTW (OR 2.714, 95%CI 1.407-5.234, p=0.003), and after 1:3 PS matching (34.0% vs 18.5%, OR 2.258, 95%CI 1.092-4.671, p < 0.05).
Conclusions: Elevated donor’s seral creatinine increased the risk of postoperative EAD, which might be a novel predictor of EAD after DCD liver transplantation.
Combined plasma lens and rephasing stage for a laser wakefield accelerator

Published: June 2024

Electrons from a laser wakefield accelerator have a limited energy gain due to dephasing, and are prone to emittance growth causing a large transverse divergence. In this paper, we experimentally show that both of these issues can be addressed in a single step, by adjusting the plasma density profile. Shock-assisted ionisation injection is used to produce 100 MeV quasi-monoenergetic electron bunches in the primary part of the accelerator. Downstream from accelerator, a second, independently tuneable density region is added which can be used to both boost the energy of the electron bunches, and as a plasma lens for significant divergence reduction. An additional energy gain of 25% and a 40% divergence reduction is obtained. The effects are validated by theoretical models.

Published: June 2024

Background
Bacterial strains in the rhizosphere may secrete an array of volatile organic compounds (VOCs), many of which are vital for inter- and intra-kingdom signaling, modulating microbe-microbe and microbe-plant interactions. In this study, we tested the plant growth promoting effect of VOCs emitted by Bacillus sp. NYG5 on several plants, focusing on VOC-induced changes in plant metabolic pathways, soil chemical properties and rhizo-microbiome.
Results
NYG5 emitted VOCs were found to promote growth of Arabidopsis thaliana, Nicotiana tabacum and Cucumis sativus, while also altering the community composition of the rhizosphere microbiome. Furthermore, fluorescent spectral analysis of the soil showed a significant decrease in concentration of humic substances following exposure to NYG5-emitted VOCs. Utilizing SPME-GC-MS analysis, several novel VOCs were identified, some of which were shown to promote plant growth. Transcriptomic analysis of N. tabacum plants exposed to NYG5-emitted VOCs revealed the induction of several plant growth related pathways such as phenylpropanoid biosynthesis, metabolism of sugars, and signal transduction of plant hormones.
Conclusions
Exposure to NYG5-emitted VOCs significantly impacted several plant growth related pathways, increasing plant biomass. Additionally, these VOCs altered the community composition of the rhizosphere microbiome, and decreased the concentration of humic substances in the soil. These findings may suggest that bacterial VOCs significantly impact plant growth via various mechanisms.
