Evaluate the physiological and sanitary quality of bean and maize seeds treated with Ocimum gratissimum extracts and eugenol-pure oil nanoemulsion
Authors: Lima Juliana Trindade , de Souza Antonio Fernando , Brunoro Isabela , De Araujo Letícia Martins , França Hildegardo Seibert
Published: February 2025

The study aimed to assess the fungicidal potential of ethanolic and dichloromethane extracts from Ocimum gratissimum leaves and eugenol-pure nanoemulsion in the preservation and viability of bean (Phaseolus vulgaris L.) and maize (Zea mays L.) seeds during storage. Seeds were soaked in 5mg/mL ethanolic extract solution, 5mg/mL dichloromethane extract solution, and 5% eugenol nanoemulsion, followed by storage in plastic containers at room temperature for 60 days. Fungi presence was noted in the seeds, prompting evaluation. Methyl thiophanate was used as a positive control and water as a negative control. Vigor analysis used filter paper as a substrate pre- and post-storage. Effects of extracts on seed germination, germination speed index, first germination number, emergence, emergence speed index, root length, and stem length were also analyzed. The fungal diversity analysis demonstrated the presence of Aspergillus, Penicillium, and Rhizopus fungi in all treatments. For beans, eugenol nanoemulsion (4.4%) showed greater pathogen reduction, while for maize, ethanolic (40.4%) and dichloromethane (43.0%) extracts were more effective. Post-storage, bean seeds treated with ethanolic extract displayed a 98.6% germination rate, while maize seeds had an 84.6% rate. However, both dichloromethane extract and eugenol nanoemulsion negatively impacted seed vigor in both crops. Results suggest that ethanolic extract from O. gratissimum leaves could be a viable alternative for protecting seeds from fungi during storage while maintaining germination ability.

Authors: Kongmanee Chaiya , Ahmed Ferdoushi , Prommee Paratta
Published: February 2025

This study investigates various environmental aspects of different rubber farming systems (i.e. conventional monoculture, integrated rubber-based farming, and agroforestry plantations) across three regions, namely Northeast, East and South in Thailand. These regions are enriched with diverse soil types, weather conditions and a diverse spectrum of agricultural practices. The study conducted a cross-sectional survey in the above-mentioned regions to collect primary data from the selected respondents. A purposive sampling technique was employed to select the samples. A total of 30 representative rubber farmers were interviewed using a structured and standardized questionnaire. In addition, the study employed qualitative methods to assess the environmental aspects of different rubber farming systems. Based on socio-economic and production criteria, the study identified five types of rubber farms, ranging from single-crop para-rubber to highly diversified operations. The analyses revealed that integrated rubber farms and rubber agroforestry farms demonstrated overall better performance compared to rubber monoculture farms, particularly in areas having higher organic matter content, DRC of rubber fresh latex, water holding capacity (WHC), and soil moisture. The study also found that ecosystem service ratings varied widely, with monoculture farms scoring low (1.98) and integrated systems scoring high (4.60). In addition, the study assessed the farmers’ desire/concern toward biodiversity of different rubber farming systems. The farmers expressed significant concern for biodiversity (average score is 4.23 indicating a consensus at the "very much" level). These findings highlight the environmental advantages of integrated rubber farming and agroforestry, emphasizing the need for sustainable, diverse approaches to rubber production in Thailand.
Interference periods of sourgrass (Digitaria insularis) on maize crop
Authors: Piazentine Ana E. , Martins Heytor L. , Rodrigues Juliana de S. , Carrega Willians C. , Alves Pedro L.C.A.
Published: February 2025

Sourgrass (Digitaria insularis (L.) Fedde) is frequently reported as one of the main weeds in grain production, along with several reports of herbicide resistance. The objectives of this study were (1) to understand the length of time that the maize crop, cv. P4285VYHR PIONEER could coexist with a weed community dominated by D. insularis plants without suffering any negative impact on its final production, and (2) the period for which the crop needs to be free of this interference to ensure optimal production. The periods of weed interference and/or control were: 15, 30, 45, 60, 75, 90, 105, and 130 days after sowing maiz, to determine the period before interference (PBI), the total period of interference prevention (TPIP), and the critical period of weed interference (CPWI). A weed community predominantly containing D. insularis coexisting with the maize crop decreases yield by up to 86%, reduces plant height, the insertion height of the first ear, and the weight of 1000 grains. Maize can coexist with such a community (PBI) for 30 DAS, tolerating yield losses of up to 5%, without TPIP and, consequently, CPWI.

Особливості напружено-деформованого стану системи «фіксатор — кістка» при остеосинтезі нижньої щелепи в ділянці кута фіксаторами з β-Zr-Ti-Nb сплаву
Authors: Романова А.Ю. , Крищук М.Г.
Published: February 2025

Актуальність. Переломи на ділянці кута нижньої щелепи, за даними більшості досліджень, є поширеним видом перелому, що асоціюється з найбільшою кількістю ускладнень, зокрема розвитком інфекції, уповільненням консолідації уламків та їх неправильним зрощенням, що має вторинні наслідки. Мета: порівняти вплив традиційних титанових фіксаторів для остеосинтезу нижньої щелепи і пластин з нового β-Zr-Ti-Nb сплаву на розподіл напружень і деформацій в елементах фіксації та кістковій тканині залежно від ступеня зрілості кісткового регенерату в ділянці кута нижньої щелепи. Матеріали та методи. Вивчення біомеханічної поведінки систем «фіксатор — кістка» при переломах у ділянці кута нижньої щелепи із застосуванням фіксаторів з різних матеріалів проводили в модельному експерименті, використовуючи метод імітаційного комп’ютерного моделювання. Було створено й обраховано 6 багатокомпонентних імітаційних комп’ютерних моделей зі змінними параметрами (моделі нижньої щелепи, накісткових пластин і гвинтів). Варіативними параметрами були механічні властивості елементів фіксації, що відповідали традиційному титановому сплаву Ti6Al4V (контроль) або β-Zr-Ti-Nb сплаву (основна група). Фізико-механічні параметри кісткового регенерату в моделях також змінювали, надаючи їм властивостей, притаманних: 1) незрілому фіброзно-кістковому регенерату; 2) регенерату з грубоволокнистої (ретикулофіброзної) кісткової тканини; 3) кістковому регенерату з ознаками компактизації. Результати. При застосуванні пластин з β-Zr-Ti-Nb сплаву на ділянці кута нижньої щелепи деформація системи, що характеризує стабільність фіксації, практично не відрізнялась від показників контрольної групи. Натомість розподіл напружень у системі між елементами фіксації та кістковою тканиною в зоні зрощення був більш рівномірним. Максимальні напруження в пластині в міру дозрівання регенерату зменшувались з 83,7 до 26,2 МПа і виявлялися в 1,5–2,5 раза меншими, ніж у контролі. Висновки. Проведені дослідження виявили низку біомеханічних переваг β-Zr-Ti-Nb пластин, що при правильному розташуванні дозволяють забезпечити необхідну жорсткість фіксації і водночас більшу міцність і надійність системи «фіксатор — кістка», а також наблизити розподіл функціональних навантажень у зоні кісткового зрощення до природного, притаманного ділянці кута нижньої щелепи.

Лобно-лицеве висування моноблоком (ЛЛВМ) є ключовою процедурою в лікуванні синдромних краніо­синостозів — групи рідкісних черепно-лицевих вад розвитку, що можуть бути пов’язані з остаточними візуальними, когнітивними та морфологічними порушеннями, якщо вчасно не надати допомогу пацієнтам. Основне завдання ЛЛВМ — усунути підвищений внутрішньочерепний тиск, екзофтальм, обструктивне апное під час сну та порушення прикусу (III клас) за одну процедуру. Цей підхід вимагає спільної роботи щелепно-лицевих і нейрохірургів у рамках спеціалізованої черепно-лицевої багатопрофільної команди. Напрямок дитячої черепно-лицевої хірургії був розроблений на основі новаторських робіт Пола Тесьє пластичним хірургом українського походження Даніелем Маршаком разом із нейрохірургом Домініком Реньє. У статті йдеться про підготовку, виконання, спостереження та результати першого ЛЛВМ, виконаного в Україні, що розкриває подальшу перспективу для створення мультидисциплінарної команди черепно-лицевої хірургії в лікарні «ОХМАТДИТ» у Києві. Також це партнерство має певний символізм у спробі Росії знищити лікарню «ОХМАТДИТ» 8 липня 2024 року.

Authors: Пономаренко Ю.В. , Гарляускайте І.Ю. , Безкоровайна Л.П.
Published: February 2025

У статті наведено клінічний випадок 15-річної пацієнтки, яка звернулася зі скаргами на біль у привушно-жувальній ділянці зліва, обмеження відкривання рота, а також іррадіацію болю у скроню, вухо та нижню щелепу зліва. Після первинного обстеження стоматологом-терапевтом пацієнтка була направлена до стоматолога-хірурга для подальшої діагностики. Зважаючи на симптоми та клінічний огляд, було запідозрено міофасціальний синдром больової дисфункції скронево-нижньощелепного суглоба, однак зниження чутливості в ділянці нижньої губи та язика вказувало на можливе ураження трійчастого нерва. Подальше обстеження, включно з електронейроміографією, електроміографією та магнітно-резонансною томографією, виявило ураження лівого нижньощелепного нерва, спричинене наявністю багатокамерного рідинного утворення в проєкції інфратемпоральної ямки, яке тиснуло на нерв. Пацієнтку направлено на консультацію до Інституту нейрохірургії ім. акад. А.П. Ромоданова для подальшого лікування. Цей випадок підкреслює важливість міжфахового підходу в діагностиці та лікуванні орофаціального болю, особливо у випадках, коли клінічна картина виходить за межі типових симптомів міофасціального синдрому. Вчасне залучення спеціалістів різних напрямків дозволяє точніше визначити етіологію симптомів та розробити відповідну тактику лікування.

Кожне поняття включало терміни MeSH та ключові слова. Для мінімізації ризику системної помилки був проведений всебічний пошук сірої літератури з використанням таких баз даних, як ProQuest, Google Scholar, OpenThesis і OpenGrey. Результати. Після видалення дублікатів, скринінгу назв і рефератів, повнотекстового читання було відібрано 34 публікації. Серед них у 27 дослідженнях оцінювали точність автоматизованого маркування на 2D бічних цефалограмах на основі ШІ, тоді як 7 досліджень включали 3D-КПКТ зображення. У більшості робот продемонстрований високий ризик системної помилки при виборі даних (n = 27) і референтного стандарту (n = 29). Висновки. ШІ-цефалометричне визначення орієнтирів як на 2D-, так і на бічних цефалограмах, синтезованих із 3D-зображень, показало досить великий потенціал з точки зору точності й ефективності використання часу.
Enhancing the Energy Efficiency of Wireless Sensor Networks in IoT
Authors: Ali Zeeshan
Published: February 2025

The core foundation of Internet of Things (IoT) systems are wireless sensor networks (WSNs). Energy limitations provide a significant problem for the wireless nodes in these networks that are in charge of sensing. The complexity results from the challenging task of recharging or replacing the batteries of these nodes, a task frequently met with great difficulty. The energy problem is made worse by the fact that many real-world IoT situations involve dynamic sensing components that are in motion. In light of these worries, the current research is carefully designed to solve the real-world difficulties posed by WSNs that include mobile sensing components. The main goal is to use concept of radio-frequency (RF) energy extraction to alleviate energy restrictions that are inherent in such settings. With a framework designed to handle mobile sensing components capable of RF energy harvesting, proposed technique presents a novel procedure for the election of cluster heads (CH) within WSNs. This method holds great potential for overcoming the persistent energy puzzles that have repeatedly hampered the smooth operation of such networks. This method's key strength is its capacity to harness RF energy, which renews the nodes' power sources and increases their operational lives. The effectiveness of the suggested strategy is exposed through thorough simulations, which puts it favorably in contrast to current methodologies. The parameters of residual energy, count of functioning nodes, and overall network longevity all highlight this approach's superior performance and highlight its potential to change the WSN landscape within the dynamic and energy-conscious IoT environment.
Designing Flexible Scheduling Algorithm for 5G
Authors: Aslam Usama
Published: February 2025

Broad machine-type communication, ultra-reliable low-latency communication, and efficient management of expanding mobile broadband traffic are now achievable with the advent of 5th-Generation (5G) wireless mobile communication standards. One of the biggest challenges for 5G networks, meanwhile, developing effective Radio Resource Management (RRM) and scheduling algorithms that meet quality of service (QoS) requirements. Widely used Proportional Fair algorithm, which primarily gives priority to customers served by a node depending on their flow rate, is the foundation of the current 5G scheduling technology. The purpose of this project is to investigate methods for improving 5G network throughput and to suggest novel scheduling schemes. This work advances the development of 5G and other mobile communication technologies by adding data flow package latency as an extra priority parameter and using MATLAB for simulation analysis. In the end, it offers a new scheduling technique that was developed through the assessment of different radio resource scheduling approaches.
Arrabales en el Quito colonial temprano: la formación de los barrios periféricos de la ciudad (1534-1575)
Authors: Espinosa-Fernández-de-Córdova Carlos , Salgado Gómez Mireya
Published: February 2025

El artículo explora la formación de los arrabales indígenas de San Sebastián y San Blas en Quito entre la fundación española de la ciudad, en 1534, y 1575, cuando los barrios fueron constituidos como parroquias. Constatamos que los arrabales son fruto de una dualidad intrínseca al urbanismo colonial, marcada por los polos complementarios damero-arrabal, para argumentar que estos barrios se engendraron en el terreno debido a tres estímulos derivados del proyecto colonial. El primero de ellos es el proceso de evangelización, que buscaba concentrar a la población indígena circundante a la ciudad en un lugar fijo. En segundo lugar, las alianzas entre los colonizadores y las altas autoridades indígenas que requerían la cercanía de estas últimas para el manejo de la población tributaria y neófita. Finalmente, el tercer impulso en la formación de los arrabales es la atracción de mano de obra indígena para la construcción de la ciudad, los oficios artesanales y el servicio doméstico. Rastrear la formación de la periferia urbana significa incluir a los indígenas en la historia de la ciudad, no como habitantes de una ocupación prehispánica que se mantiene latente, sino como actores en la configuración de la ciudad colonial.

risks, and ensure the overall safety and wellbeing of donors. This paper reviews various types of IoT sensors used in health
monitoring, such as heart rate monitors, pulse oximeters, and temperature sensors, and discusses their integration with blood
donation applications. It also explores different machine learning models used for health data analysis and their effectiveness in
providing personalized recommendations.
The review highlights the current trends in blood donation applications, including the development of user-friendly interfaces
and the incorporation of features that enhance donor engagement and experience. Case studies of successful implementations of
IoT and machine learning in blood donation are presented, demonstrating the practical benefits and impact of these
technologies on the efficiency and safety of the donation process.
Despite the promising advancements, several challenges and limitations exist in integrating IoT and machine learning into blood
donation systems. These include technical challenges related to the interoperability of diverse IoT devices, the accuracy and
reliability of machine learning models, and significant concerns regarding data privacy and security. The paper discusses these
challenges in detail and proposes potential solutions and future directions for research and development

Published: February 2025

Este trabalho analisa a representação social dos alunos iniciantes do curso de Letras/Espanhol da Universidade do Estado do Rio Grande do Norte (UERN), Campus de Pau de Ferros, sobre a lí­ngua espanhola, com fins a descrever os elementos temáticos que constituem tal representação. Para tanto, fizemos uma análise discursiva dos significados que estes alunos atribuem à lí­ngua espanhola com base em Irineu (2011). Metodologicamente, optou-se pela aplicação de questionários, como técnica de geração dos dados. Sobre esse viés, o corpus de nossa pesquisa foi gerado e constituí­do pelo material discursivo proveniente da aplicação dos referidos questionários. Como fundamentos teórico-metodológicos, amparamo-nos na Teoria das Representações Sociais, elaborada por Sèrge Moscovici (1976) e complementada por Denise Jodelet (2001), Jean Claude-Abric (2001) e Willem Doise (2001), dentre outros estudiosos do fenômeno em debate. As análises dos dados mostram que o grupo social em questão constrói sua RS sobre a lí­ngua espanhola com base nas crenças e nas imagens consensuais que circulam na sociedade sobre este idioma considerado como uma lí­ngua fácil, de gramática difí­cil, mas que encanta a todos com seu sotaque diferenciado. As análises evidenciam ainda que os elementos temáticos evocados pelos sujeitos da pesquisa orientam os posicionamentos e as atitudes do grupo em relação ao objeto de representação, com base em tomadas de posição simbólicas amparadas no universo consensual dos sujeitos.

Este trabalho propõe o debate de questões que envolvem o processo de aprendizagem formal da lí­ngua materna, a partir de abordagens e métodos que enfatizam a elaboração de programas que buscam auxiliar aos alunos a desenvolverem competências linguí­sticas, e a refletirem a formação e a utilização de conceitos nos processos de interação social e no desenvolvimento desses conceitos. Como aporte teórico, Luft (2005), Soares (2002) e Vigotskii (1999, 2001) fundamentaram as reflexões sobre lí­ngua e interação social. Por meio da revisão da literatura foi possí­vel estabelecer um panorama teórico sobre as contribuições da interação social para a aprendizagem da lí­ngua nos contextos familiar e escolar. Os resultados direcionam ao incentivo de atividades cognitivas que exijam a formação de conceitos como elemento fundamental da aprendizagem, dessa forma, as reflexões expostas fornecem encaminhamentos pragmáticos para se pensar o ensino e suas reformas.
Análise do discurso na aula adicional sob dupla perspectiva: dialógica e discursiva
Authors: Pinho Louise S. do
Published: February 2025

Apresentaremos neste artigo uma proposta de análise do discurso para a aula de lí­ngua espanhola como lí­ngua adicional na quais duas teorias são postas em diálogo: a análise de discurso de linha francesa e a análise dialógica do discurso. Nosso objetivo é chegar a uma alternativa para a atividade de análise do discurso na sala de aula na qual os diversos olhares sobre o objeto de análise emirjam, fazendo com que o aluno perceba que o gênero discursivo possui diversas significações, de acordo com o ponto de vista que se adote para analisá-lo. O aporte teórico utilizado está baseado nas ideias do Cí­rculo de Bakhtin, em autores que o estudam, como Faraco, e em estudiosos da análise de discurso de linha francesa, principalmente Orlandi. A partir da análise de propagandas de ração de cachorro, percebemos que, apesar de ambas as teorias possuí­rem conceitos que divergem, quando observamos o objeto de análise considerando ambos os pontos de vista a atividade torna-se mais produtiva e enriquecedora, pois, principalmente, proporciona a consciência de que não existe uma só interpretação e um só olhar possí­vel. O professor de lí­nguas deve ser plural e não limitar-se a apenas uma teoria tida como verdade absoluta, assim como a aula deve ter espaço para múltiplas visões.
A divulgação cientí­fica nas mí­dias sociais: o caso do blog Bússola
Authors: Ferreira Rejane Ricardo
Published: February 2025

A presente pesquisa tem como objetivo compreender como o blog Bússola, que integra o site da revista cientí­fica Ciência Hoje, se organiza e em que medida contribui para o processo de divulgação da ciência para a sociedade em geral. Para isso, foram observados aspectos relacionados à organização das informações e as diferentes estratégias discursivas empregadas pelo enunciador com o intuito de informar e também de suscitar maior interesse pela leitura por parte dos internautas. Para a fundamentação teórica, empregou-se a teoria Semiolinguí­stica, que sustenta a noção de contrato de midiatização cientí­fica proposto por Charaudeau (2008) e estudos de Adam e Lugrin (2000) sobre hiperestrutura. Além disso, aproveitaram-se as categorizações sugeridas por Primo (2011) acerca do termo Interatividade e as considerações propostas por Xavier (2009) que abordam a noção de Hipertexto, pois se levou em conta que o blog possui caracterí­sticas pertinentes í s iniciativas de webjornalismo. Utilizou-se na presente pesquisa ideia apresentada por estudiosos da divulgação cientí­fica como Charaudeau (2008) e Vogt (2006), entre outros. O desafio deste estudo é mostrar que a simplicidade do discurso empregado, a escolha de imagens e de sinais de pontuação e a organização de uma postagem no blog formam um conjunto de estratégias que podem servir para transformar a linguagem cientí­fica em uma linguagem acessí­vel a todos.
Faça o que eu digo e faça o que eu faço: reflexões teóricas sobre estratégias da argumentação
Authors: Santos Leusa Cristina Bezerra dos
Published: February 2025

Este artigo discute no campo teórico algumas estratégias argumentativas para alcançar os objetivos centrais de toda argumentação: o convencimento e a persuasão. Recorremos a Perelman e Tyteca (2005) e Garcia (1995) para a discussão sobre audiências e argumentações formais e informais. A Carraher (1983) vinculamos a discussão sobre a necessidade do senso crí­tico necessário diante de toda argumentação. Charaudeau (2006) utilizamos sua contribuição ao tratar sobre a articulação entre a emoção e a verdade nas argumentações jornalí­sticas e publicitárias. Pretendemos, com esse trabalho, encaminhar uma reflexão sobre como repousam subliminarmente as estratégias argumentativas e de que forma podem lograr êxito perante suas audiências.
Multipartite entanglement distribution in a topological photonic network
Authors: Zurita Juan , Agustí Casado Andrés , Creffield Charles E. , Platero Gloria
Published: February 2025

In the ongoing effort towards a scalable quantum computer, multiple technologies have been proposed. Some of them exploit topological materials to process quantum information. In this work, we propose a lattice of photonic cavities with alternating hoppings to create a modified multidomain SSH chain, that is, a sequence of topological insulators made from chains of dimers. A qubit is then coupled to each boundary. We show this system is well suited for quantum information processing because topological transfer of photons through this one-dimensional lattice can entangle any set of qubits on demand, providing a scalable quantum platform. We verify this claim evaluating entanglement measures and witnesses proving that bipartite and multipartite entanglement is produced, even in the presence of some disorder.

Authors: Abu-Shaikha Ma'in , Nasereddin Sara
Published: February 2025

The research investigates the role of media relations and corporate communications strategies of architectural firms that conventionally pursue PR methodologies and data-driven approaches have evolved. This has led to the conduct of research studies that use qualitative insights coupled with predictive modelling. These are used to examine how companies are evolving their communications approach in the digital age. This study investigates ten leading architecture firms, assessing communication effectiveness through qualitative interviews, media content analysis, and social media metrics. This further predicts the stakeholder engagement and media impact by applying machine learning models- Random Forest and LSTM networks with an accuracy of 85%. Key findings include that the drivers of engagement based on sentiment, content share ability, and media timing are significant. The study demonstrated how data-driven insights can drive strategic decision-making, optimize public relations, and improve stakeholder engagement. Moreover, the study provides an easily scalable framework for forecasting purposes in different markets. Further, it shows the promise of AI-driven communication strategies. Combining corporate communications theory with advanced analytics, this study shows how companies can benefit from the increasingly digital nature of media relations. This has been a major need for proactive reputation management and strategic content distribution. It enables architecture firms and others to better adapt to changing waves of media in response to maximal positive engagement.

The research included the formation of chalcone derivatives, which are organic materials with biological importance, on which this research is based. The Chalcone derivatives were synthesised from the Claisen-Schmidt condensation reaction. Compounds I-III were synthesised by reacting p-aminoacetophenone with (4-methylbenzaldehyde,2,3-dimethylbenzaldehyde, and cinnamaldehyde), respectively, in an ethanolic solution of KOH (30%). Chalcones were characterised byFourier transform infrared spectroscopy (FT-IR) and proton nuclear magnetic resonance (1H NMR). The cytotoxicity effect was demonstrated in human melanoma cells A-375 and HdFn normal cells, and the MTT results showed that the cytotoxicity of Chalcone derivatives was greater than HdFn cells. The ability to use Chalcone derivatives as sunscreen showed a promising result.

The Schiff bases (E1-E3) are generated by reacting azo derivative (A) with different amine derivatives. The Schiff bases (E1-E3) are obtained via the reaction between azo derivative with 4-methylbenzaldehyde, 4-ethyl-benzaldehyde, and 4-hydroxy-benzaldehyde. The Schiff base E1 namely:2-[(4-methylphenyl)diazenyl]-4-{(E)-[(4-methylphenyl)imino]-methyl}phenol; E2:4-{(E)-[(4-ethylphenyl)imino]-methyl}-2-[(4-methyl-phenyl)diazenyl]phenol; E3:4-{(E)-[(4-hydroxyphenyl)imino]methyl}-2-[(4-methylphenyl)diazenyl]phenol. All synthesized derivatives are characterized based on physical characteristics and spectroscopy methods, such as FT-IR and 1H-NMR. Schiff bases derivatives exhibit notable activity against Staphylococcusaureus, Escherichia coli, and Bacillus subtilis, and the derivative (E3) was particularly effective against all tested bacterial strains due to a hydroxy group in its structure. In silicoresults are the derivative E1is exhibiting multiple interactions with the glucosamine-6-phosphate (GP6)receptor most notably a hydrogen bonding between GLU488 and the azo group and others.

Antimicrobial-resistant (AMR) bacterial infection is major challenges for global health systems. Pseudomonas aeruginosa is the most important clinical and epidemiological microorganisms. It is the most common cause of nosocomial infections among non-fermenting,Gram-negative bacteria and the most common cause of opportunistic infections in patients with diseases. P.aeruginosa samplewere collected from two hospitals (Al-Kadhimiya and Abu Ghraib Hospital)from the beginning of November to the end of December 2023, and identified using standard microbiological methods. All isolates were evaluated for the production of virulence factors (biofilm formation and protease activity). Four isolates with the highest values of virulence factors were selected for further analysis of antibiotic and probiotic susceptibility using broth dilution test. The study results revealed the presence of 27 samples of Pseudomonas aeruginosa bacteria, which is equivalent to 22.5% of the total 120 samples examined were identified. All isolatesproduced varying amounts of biofilm and protease. Four most virulent isolates were selected for susceptibility testing. All four isolates showed susceptibility to the tested antibiotics and probiotics, and significant growth inhibition was observed. This study revealed the presence of P. aeruginosa isolates with different virulence potential in Baghdad hospitals. Highly virulent isolates showed susceptibility to the tested antibiotics and probiotics, suggesting the need for further investigation of alternative treatment strategies besides conventional antibiotics

COVID-19 vaccines have shown good efficiency in clinical routs, but some people may be infected after vaccination. The objective of the present study was to review the risk factors for COVID-19 infection after vaccination and to define the characteristics of the disease post-vaccination. her survey was conducted among 451 participants of both sexes, ranging in age from 18 to over 60 years, and also included information about COVID-19 patients, including their weight, blood type, geographic location, symptoms, diagnosis, health risk factors, and duration of infection. In our study, people vaccinated with COVID-19 vaccines (Pfizer, Sinopharm, and AstraZeneca) showed fewer symptoms compared to those who were unvaccinated, with the Pfizer vaccine being particularly effective in reducing symptoms. The degree of persistence of symptoms was reduced. There was an increase in those with chronic conditions, but by less than a month indicating that vaccination may mitigate the severity and duration of symptoms in COVID-19 patients.

Nowadays, with the continuously increasing advances in understanding cancer system biology.It has led to the discovery of valuable disease-specific biomarkers. Bytargeting these markers using molecular-basedtechniques a highly specific and sensitive measurements can be obtained. Molecular diagnosis through PCR-based methods and next-generation sequencing (NGS) can detect many diseases caused by DNA and RNA changes that cannot be detected through antibody-based techniques. RT-qPCR isa valuable tool in measuring biomarker’stranscriptional signature and will have a great potentialin personalized medicine or molecular diagnostics. In related gene expression analysis, using a suitable reference gene is crucial for the accurate interpretation of the results. For this reason, ref. gene should be validated for particular tissue, cell and experimental conditions. This study was conducted to identify and validate the most suitable housekeeping gene(HKG)as a reference(ref.)gene to obtain accurate normalization for AXL receptor tyrosine kinasegene expression in Formalin-Fixed Paraffin-Embedded “FFPE” of breast cancer tissues. Based on the five different statistical algorithms used, ACTB was the least variable ref. gene and -GLOBIN showed the highest variability. Norm finder, Best Keeper and the comparative ΔCt method suggested to use ACTB as a ref. gene in our experiment while geNorm suggested to use the combination of both ACTB and UBC since they had the same exact stability value. In conclusion, Reffinder suggested that ACTB had the least geomean of ranking values of the four used methods showing the least variance among the other genes and the three groups of our samples.
