Published: December 2023

Особливості оброблення глибоких отворів – недостатня жорсткість інструмента та його висока схильність до пружних деформацій під дією сили різання. Зі збільшенням довжини отвору складність забезпечення високої продуктивності і необхідної точності поверхні різко зростає.

Insufficient tool rigidity and high susceptibility to elastic deformation under the action of cutting forces are features of machining of deep holes. As the length of the hole increases, the difficulty of ensuring high productivity and the required surface accuracy increases.
Система управління мехатронним амортизатором
Authors: Цимбалюк А.С. , Ночніченко І.В.
Published: December 2023

На сьогоднішній день технології у напрямках демпфування та амортизації транспортних засобів розвинулися до рівня, коли їхні характеристики можна регулювати залежно від температури навколишнього середовища, типу дорожнього покриття та інших зовнішніх факторів. Більше того, залучення мехатронних систем дозволяє створювати адаптивні амортизатори, які самостійно підлаштовуватимуться під зовнішні умови для забезпечення оптимальної жорсткості. Регульовані амортизатори дозволяють контролювати жорсткістну характеристику амортизатора в цілому. Метою даної роботи є розробка мехатронної системи управління керованого гідравлічного амортизатора. В даний час однією з основних тенденцій розвитку світового гідроприводу є постійно розширюється використання інтелектуальних компонентів електро-гідравлічної автоматики на основі дроселюючих гідророзподільників або пропорційних гідроапаратів з цифровими системами управління. Цифрова технологія в порівнянні з аналогової дозволяє розширити діапазон регулювання, істотно підвищити надійність, поліпшити властивості компонентів (гістерезис, швидкодія, лінійність), забезпечити відмінну повторюваність, надійне зберігання даних, діагностування несправностей, спрощення програмування і прямий зв'язок з промисловим комп'ютером. Разом з тим, для зв'язку ПГА з електричними системами управління традиційно використовуються задавальні пристрої (пропорційні електромагніти або лінійні двигуни), що працюють по аналоговому принципом, тому в чисто цифрових приводах доцільна їх заміна кроковими електродвигунами.

Аналіз прогресивних інструментів для оброблювання отворів на верстатах з ЧПК
Authors: Каменєв П.К. , Полянський М.В. , Ковальов В.А.
Published: December 2023

При оброблюванні заготовок на верстатах з ЧПК нерідко виникає необхідність свердління отворів, вісь яких проходить під кутом до оброблюваної поверхні, або отвір знаходиться на конусній чи криволінійній поверхні. В цих випадках виникають труднощі направлення свердла без попереднього центрування. Також важливо виконувати попереднє центрування для свердл із швидкорізальної сталі з великою довжиною робочої частини, які можуть відхилятися від осі під дією осьової сили, оскільки контакт вершини свердла відбувається по лінії поперечної різальної кромки.

When machining workpieces on CNC machines, it is often necessary to drill holes, the axis of which passes at an angle to the work surface, or the hole is on a conical or curved surface. In these cases, it is difficult to direct the drill without pre-centering. It is also important to perform pre-centering for high-speed steel drills with a large working part length, which can deviate from the axis under the action of axial force, because the contact of the drill bit is along the line of the transverse cutting edge.

В першому удосконаленому його зразку для випробування на стиск отвір циліндра розташований з ним співвісно, а бурт має зовнішню поверхню овальної або еліптичної форми, що збільшує кількість його ділянок із змінною товщиною в два рази. В наступному зразку для випробування на стиск отвір циліндра також розташований з ним співвісно, бурт має однакову товщину, а перехідний торець між поверхнями циліндра і бурту розташований з нахилом.
It is shown that the compression test specimen is improved in the form of a cylinder with a flange at one end of its variable thickness around the hole and its axis is offset from the axis of the cylinder, which increases the performance of the compression test in determining the optimal flange thickness, but not enough . In its first improved compression test specimen, the cylinder bore is coaxial with it, and the flange has an oval or elliptical outer surface, which doubles the number of sections with variable thickness. In the following sample for the compression test, the hole of the cylinder is also located coaxially with it, the flange has the same thickness, and the transition end between the surfaces of the cylinder and the flange is located at an angle.

VOLUNTARIADO MADURO PARA JOVENS NO MUNDO DOS POBRES: LUGAR HISTÓRICO-PASTORAL-TEOLOGAL
Authors: Severino Eduardo Roberto
Published: December 2023

Objetiva-se correlacionar a compreensão de voluntariado para jovens no Documento 85 da CNBB, Evangelização da juventude: desafios e perspectivas pastorais (2007), com os princípios do método teológico de Jon Sobrino do “mundo dos pobres como lugar histórico-pastoral e como lugar histórico-teologal”. No referido Documento, o voluntariado apresenta-se como pista da ação evangelizadora da juventude (n. 174) e da pedagogia de formação de jovens, na qual a experiência tenha prioridade sobre a teoria (n. 146-149). Ele se contrapõe à desintegração e à desvinculação entre, de um lado, protagonismo e participação sociais (n. 10-50) e, de outro, conhecimento de Jesus Cristo e confissão de fé cristã, pessoal e comunitária (n. 51-92). Desde os princípios do método teológico sobriniano, o voluntariado maduro, como forma solidária de participação social para jovens no mundo dos pobres, é lugar histórico-pastoral e lugar histórico-teologal. A incubatio do itinerário pessoal-eclesial-social-teologal do método teológico sobriniano se inscreve no desafio pastoral de repensar eclesial-social-teologicamente o voluntariado para jovens.

Novelty and appropriateness are two fundamental components of creativity. However, the way in which novelty and appropriateness are separated at behavioral and neural levels remains poorly understood. In the present study we aimed to distinguish behavioral and neural bases of novelty and appropriateness of creative idea generation. In alignment with two established theories of creative thinking, which respectively emphasize semantic association and executive control, behavioral results (n = 1,519) indicated that novelty was supported by associative ability, while appropriateness was supported by executive function. Next, employing a connectome predictive modeling (CPM) approach in resting-state fMRI data (n = 1,455), we defined two functional network-based models—dominated by interactions within default network (DMN) and by interactions within limbic network (LIM)—that respectively predicted novelty and appropriateness (i.e., cross-brain prediction). Furthermore, the generalizability and specificity of the two functional connectivity patterns were verified in additional resting-state fMRI and task-fMRI. Finally, the two functional connectivity patterns respectively mediated the relationship between semantic association/executive control and Novelty/appropriateness. These findings provide global and predictive distinctions between novelty and appropriateness in creative idea generation.

Published: December 2023

Background
Specific global conditions and the occurrence of corona pandemic and the high level of stress created due to the high risk and power of its contagion lead to double stressful conditions in medical personnel. Therefore, burnout and its related factors are very important in physicians and treatment staff related to patients with Covid-19. To determine the relationship between burnout and depression, anxiety and stress in physicians and treatment staff working in related wards of patients with Covid-19.
Methods
This cross-sectional study was performed on 108 medical staff who were in direct contact with patients with Covid-19. The Goldard questionnaire was used to assess the frequency of burnout. The DASS-21 questionnaire was also used to assess depression, stress and anxiety in the subjects. The State-Trait Anxiety Questionnaire was used to assess state and trait anxiety.
Results
84.2% of treatment staff had level 3 burnout, which as a result was not in good condition. Also, 60%, 70.4% and 64.8% of people had different degrees of depression, anxiety and stress, respectively. 84.3% and 79.6% of these people also had moderate anxiety and moderate traits, respectively. All of these factors were significantly associated with burnout. Also, stress was the most important predictor of burnout in physicians and medical staff.
Conclusions
As a result, it seems necessary to provide solutions such as the use of support packages (financial and non-financial) as well as the implementation of a systematic psychological programs - in groups or individually - to reduce stress and anxiety of these people.

PubChem Bioassays (AID 1063) reported the in vitro testing of 196 441 compounds against Leishmania major promastigotes. Although these results have been publicly available since 2008, limited efforts on further testing of some of these compounds has been published. The aim of the present work was selecting a small set of compounds that were highly active in that primary assay and assessing their antileishmanial activity in vitro and in vivo. Selected compounds were 100 % active in the primary assay at 10 μM, were not theoretically toxic, did not have structural features of pan assay interfering substances, had positive druglikeness, were not cytotoxic and their activity rate in previous assays reported in PubChem Bioassays was under 5 %. Seven commercially available compounds were purchased and tested against L. major, Leishmania mexicana, Leishmania amazonensis and Leishmania infantum promastigotes; in mouse peritoneal macrophages (cytotoxicity); and against L. mexicana intracellular amastigotes. Eventually, four compounds with appropriate selectivity and high activity against L. mexicana amastigotes were tested by intralesional route (1 %, 20 μL) in a mouse model of cutaneous leishmaniasis. Four compounds were active (IC50<10 μM) against the promastigote stage of the four Leishmania species tested. These four compounds were also active (IC50< 10 μM) in vitro against intracellular amastigotes and in vivo in mice experimentally infected with L. mexicana. Results demonstrated the potential of these compounds as antileishmanials and the high, unexploited potential of AID 1063 as a source of new antileishmanial agents.
Knowledge, attitude and practices towards cervical cancer and its screening among Women from tribal population of Anuppur district
Authors: Gupta Bharti , Parikipandla Sridevi
Published: December 2023

Cervical cancer is a significant public health issue, particularly among women from tribal populations, who face challenges in accessing healthcare services. The primary cause of cervical cancer is high-risk human papillomavirus (HPV) infection. This study aimed to comprehensively assess the knowledge, attitude, and practice of women belonging to a tribal population regarding cervical cancer and HPV screening. The research was conducted in Anuppur, a rural district in Madhya Pradesh, India, characterized by limited diagnostic facilities for HPV infection and cervical cancer. The findings of the study revealed a disturbing lack of awareness among tribal women about cervical cancer and its link to HPV infection. Many participants demonstrated a limited understanding of the risk factors, symptoms, and preventive measures associated with cervical cancer. This knowledge gap contributed to a negative attitude towards screening, as the importance and benefits of early detection and prevention were not well understood. Moreover, the study identified significant barriers to the practice of HPV screening among tribal women, including financial constraints, cultural beliefs, and limited accessibility to healthcare facilities. The utilization of screening services was low, with many participants having never undergone any form of cervical cancer screening. These findings underscore the urgent need for targeted interventions and educational programs to address the knowledge gaps and improve awareness among tribal women regarding cervical cancer and HPV infection. Such interventions should emphasize the significance of regular screening, dispel misconceptions, and promote positive attitudes towards preventive measures.

Authors: Gómez-Martínez Vanesa , Chushig-Muzo David , Veierød Marit B. , Granja Conceição , Soguero-Ruiz Cristina
Published: December 2023

Background: The global incidence of skin cancers, particularly melanoma, the deadliest among them, has risen in recent decades. Artificial Intelligence (AI) has yielded remarkable results across diverse domains including healthcare. However, most AI models for skin cancer prediction primarily focus on a single data type or modality, such as images. Emerging research highlights the potential of multimodal approaches to enhance predictive performance and interpretability in clinical tasks.
Methods: In this work, the effectiveness of multimodal fusion methods —including early and late fusion— for the detection of melanoma is assessed. Three public skin image datasets (ISIC, PH2, and Derm7pt) were considered, and two types of modalities were used, including dermoscopy images and tabular data comprising metadata, image features, and image embeddings. This study employed AI-based image classification and extended feature extraction to capture the color and texture characteristics of skin lesions, aiming to discover factors related to melanoma.
Results: Experimental findings reveal that the proposed multimodal fusion methods outperform single-modality models. Early fusion methods achieve the highest classification results, with an overall AUCROC of 0.873, 0.963, and 0.857 for ISIC, PH2, and Derm7pt, respectively. Compared with models trained with single-modality data, fusion approaches exhibited notable improvements of 6.67% (ISIC), 8.27% (Derm7pt), and 7% (PH2) in AUCROC. Two post-hoc techniques were used for detecting salient regions in dermoscopy images and identifying the most relevant image features for melanoma diagnosis.
Conclusions: These results hold promise for early skin lesion detection, contributing valuable support to dermatologists in their daily practice.
First-order loss estimation for subaqueous mass-movement generated tsunamis on perialpine lakes
Authors: Strupler Michael , Papadopoulos Athanasios N. , Wiemer Stefan
Published: December 2023

Subaqueous mass movements can trigger tsunami waves not only in the oceans, but also on lakes. For a few Swiss perialpine lakes, tsunamis have been documented in historical reports (e.g. Cysat 1969; Favrod 1991), mainly caused by earthquake-triggered subaqueous mass movements. In addition, results from numerical modelling show that tsunamis may occur again on perialpine lakes (e.g. Hilbe and Anselmetti 2015). To be prepared for such events, a quantitative risk assessment is essential. Although several authors have tried to quantify marine tsunami risk, the possible impact of lake tsunamis remains understudied. Herein, we leverage recent work that modeled possible earthquake-triggered mass movement tsunami scenarios on the well-investigated Lake Lucerne in Switzerland and proceed to obtain some fist-order estimates of possible earthquake- and tsunami-induced economic losses. We use tsunami intensity footprints, in terms of flow depth and momentum flux, conditional on subaqueous mass movements triggered by 475- and 2475-year ground motions. These are overlaid with the built exposure at the village of Buochs-Ennetbürgen, located at the shore of Lake Lucerne. Earthquake and tsunami damage is computed based on fragility and consequence information retrieved from the Earthquake Risk Model of Switzerland (ERM-CH23) and the HAZUS tsunami model. Earthquake and tsunami losses are further contrasted and discussed. This work provides a first analysis of the tsunami risk around perialpine lakes.

The duration target will directly affect the effectiveness of the implementation of the residential building project, so it is necessary to predict a reasonable residential building duration. In this work, genetic algorithm (GA) is used to optimize and improve the weights and thresholds of the BP neural network to form a GA-BP neural network model, and seven parameters, such as aboveground building structure, number of building floors, building area, decoration standards, foundation structure, number of underground building floors, and underground building area, are taken as the input parameters of the neural network model, and the residential building duration is taken as the output parameter. 111 sets of residential building duration data were collected and divided into 90 training sets and 21 test sets, and the model was validated and analyzed in comparison using root mean square error (RMSE), correlation coefficient (R) and average error rate, which were used to validate that the GA-BP neural network model helps in predicting the duration of residential buildings. In order to improve the prediction accuracy of GA-BP neural network model, this work uses artificial bee colony improved K-means clustering algorithm to classify 111 sets of experimental data and 33 sets of new data, according to the classification of the training and testing results show that the ABC-K-means-GA-B model all have a strong generalization ability and strong prediction accuracy, and at the same time, it proves that this paper's proposed ABC- K-means-GA-BP neural network helps to predict the construction period of residential buildings, which is of great practical significance for improving construction efficiency.

Authors: Dongxue Guo , Fangfei Zhao , Ran Li , Lizhi Zhou
Published: December 2023

Purpose: To investigate the effect of gradient pressure therapy on the prevention of chemotherapy-induced peripheral neuropathy (CIPN) and improvement in activities of daily living (ADL) in patients with breast cancer.
Methods: Eighty female patients with breast cancer were selected as research participants and divided into control and intervention, with 40 patients in each group. The control group received routine treatment and care, whereas the intervention group received gradient pressure therapy based on routine treatment and care. Incidence of peripheral neuropathy and degree of impact on ADL between the groups were compared after the intervention for cycles 2, 4, and 6.
Results: There was no statistically significant difference in the general information between the two groups (P>0.05). After two intervention cycles, there was no significant difference in the incidence of CIPN, various dimensions of Chemotherapy-Induced Peripheral Neuropathy Assessment Tool (CIPNAT), and total scores between the groups (P>0.05). After four intervention cycles, the two groups had a statistically significant difference in the incidence of CIPN, sensory dimension, general activity dimension, and total CIPNAT score (P<0.05). After six intervention cycles, there was a significant difference in the incidence of CIPN, sensory dimension, fine activity dimension, general activity dimension, and total CIPNAT score between the two groups (P<0.05), while there was no significant difference in the other dimensions (P>0.05).
Conclusions: Gradient pressure therapy can effectively prevent or alleviate peripheral neuropathy in patients with breast cancer undergoing chemotherapy and improve their ability to perform ADL. Thus, it is safe, effective, and worthy of clinical application.

Authors: Thiamngeon Phattharamat , Pinpatthanapong Khathapon , Juntadech Nithinart C. , Rangseesuriyachai Thaneeya
Published: December 2023

Cattail cellulose microfibers were produced through a sequence of hydrothermal (HTP) and sodium hydroxide (NaOH) pretreatments, followed by the synthesis of deep eutectic solvent (DESs). This study focuses on assessing the oil-adsorption capacity of these microfibers and explores the preparation of optimized adsorbent materials. The optimization involves DESs synthesis at temperatures of 50, 70, and 90°C, following a two-stage pretreatment process, including HTP at 180°C for 2 h and NaOH treatment at 90°C for 1 h, with an emphasis on maximizing cellulose content, hemicellulose removal, and delignification. Various oil absorption tests were conducted using the resulting absorbent materials under suitable conditions. The findings highlight that the optimal temperature for DESs synthesis is 70°C, resulting in microfibers with a composition of 43.13% cellulose, 3.88% hemicellulose, and 8.6% lignin. These absorbent materials exhibit a remarkable oil absorption capacity, capable of absorbing a variety of oils at a consistent rate of approximately 6–7 g/g. Notably, these cellulose fiber materials outperform conventional oil-absorbing materials while utilizing environmentally abundant cattails.
Technical considerations for cost-effective Transposon Directed Insertion-Site Sequencing (TraDIS)
Authors: Kyono Yasuhiro , Tolwinski Madeline , Flowers Stephanie A.
Published: December 2023

Transposon Directed Insertion-Site Sequencing (TraDIS) is a high-throughput assay that defines essential bacterial genes across diverse growth conditions. However, the variability between laboratory environments often requires laborious, time-consuming modifications to its protocol. In this technical study, we aimed to refine the protocol by identifying key parameters that can impact the complexity of mutant libraries. Firstly, we discovered that adjusting electroporation parameters including transposome concentration, transposome assembly conditions, and cell densities can significantly improve the recovery of viable mutants for different Escherichia coli strains. Secondly, we found that post-electroporation conditions, such as recovery time and the use of different mediums for selecting mutants may also impact the complexity of viable mutants in the library. Finally, we developed a simplified sequencing library preparation workflow based on a Nextera-TruSeq hybrid design without compromising the ability to detect transposon-DNA junctions.

Published: December 2023

Computational Fluid Dynamics (CFD) simulations are widely used to develop and analyze blood-contacting medical devices such as Left Ventricular Assist Devices (LVADs). This work presents an analysis of the transient behavior of two centrifugal LVADs with different designs: HeartWare VAD and HeartMate3. A scale-resolving methodology is followed by means of Large Eddy Simulations. The 3D LVAD models are coupled to a 0D 2-element Windkessel model, which accounts for the vascular resistance and compliance of the arterial system downstream of the device. Furthermore, both continuous- and pulsatile-flow operation modes are analyzed. For the pulsatile conditions, the artificial pulse of HeartMate3 is imposed, and CFD results are compared to those obtained by accessing the quasi-stationary maps of the pumps. Although the quasi-stationary results in terms of efficiency and hemolysis are not realistic, this approach can be used as a rapid tool to provide a preliminary approximation of the pulsatile evolution of flow rate, pressure head, and power, entailing a significant reduction of 99% in computational cost.

Published: December 2023

Ion propulsion systems with a small thrust can be used in space missions for highly accurate controllability while possessing low power and propellant consumption.
At the University of Giessen, radio-frequency ion thrusters are miniaturized with thrusts in the order of micro-Newtons ($\mu$N-RIT).
As the size of the thruster becomes smaller the plasma properties can not be measured inside a closed plasma chamber.
The simulations are needed to investigate plasma properties which would aid further opimization.
In this work, we present kinetic simulations of plasma inside the RIT-1.0 thruster using in-house developed PlasmaPIC code that incorporates Monte-Carlo collisions (MCC) and Direct Simulation Monte Carlo (DSMC) for neutral gas distribution.

In sub-Saharan Africa (SSA), over 75% of the population must spend time walking to collect water from outside their home, with women and girls bearing the majority of the time burden. The proximity of households to their water source can affect child health, with more distant water sources associated with higher child diarrhea and mortality. Climate change is predicted to alter water availability in SSA through increased temperatures and changes in precipitation. Here, we used spatial first differences to estimate the causal effects of preceding weather over time periods ranging from one week to one year on household water fetching times. We merged nationally representative household survey data (n=979,759 observations collected from 34 countries) with geo- and temporally-linked precipitation and temperature preceding the date of each household survey. Increased precipitation reduced water fetching walk times; a 1cm increase in weekly rainfall over the past year was associated with a 5.1 min decrease in walking time. Elevated temperatures increased walk times; a 1°C increase in temperature over the past year was associated with a 1.2 min increase in walking time. Rural household water fetching times were more impacted by recent weather than in combined urban and rural households; however, higher electricity access in rural communities mitigated the effect. Our findings suggest that future climate change will increase the water fetching burden in SSA, but that co-provision of electricity and water infrastructure may be able to alleviate this burden.

Published: December 2023

Wireless communication has continually faced challenges associated with fading propagation channels, with detrimental effects arising from multipath fading. Though effective in addressing these challenges, traditional diversity techniques often require multiple antennas, which a transmitter's size can constrain. This study introduces an innovative approach to overcoming these limitations through cooperative diversity. By leveraging cooperative diversity, we enable single-antenna terminals to create a virtual multi-antenna array, thereby achieving the benefits of spatial transmitting diversity without the need for physical multiple antennas. We built our cooperative system around the Alamouti code, where two relays cooperate: each relay captures, processes, and cross-verifies the transmitted information with its counterpart to ensure accuracy. This cross-verification significantly mitigates the chances of data errors. The processed data is then collectively transmitted to the intended Destination. This cooperative mechanism inherently reduces noise interference, ensuring a higher-quality signal transmission. Through extensive simulations, our results demonstrate a notable reduction in bit error rates, making a solid case for the superiority of our two-relay scheme over conventional single-relay models. Incontrovertibly, our proposed transmission mechanism provides improved signal performance and increased stability in signal propagation, representing a notable advancement in the field of wireless networks.

The deployment of 5G infrastructure is one of the main vectors for new application scenarios since it enables enhanced data bandwidth, low latency, and comprehensive signal coverage. As a result, this communication system supports various vertical applications such as the Industrial Internet of Things, smart health, smart cities, smart grids, and transportation systems. However, these applications bring new challenges to 5G networks due to specific requirements for such scenarios. Furthermore, as software-based technologies, including network slicing, software-defined networks, network function virtualization, and multi-access edge computing are a fundamental part of the 5G architecture, the network can expose these applications to new security and privacy concerns. This study summarizes the existing literature on 5G vertical applications security. We highlight vulnerabilities, threats, attacks, and solutions for 5G vertical applications. We conducted a Systematic Literature Mapping (SLM) to discuss security and privacy challenges regarding the 5G vertical applications. The SLM answered the following research question: what is the state-of-the-art regarding security in 5G networks and vertical applications? We reviewed 389 papers from 2,349 produced by searching with a curated search query and discussed vulnerabilities, threats, attacks, and solutions for 5G vertical applications. Smart cities, Industry 4.0, smart transportation, public services, smart grids, and smart health are vertical applications with relevant security concerns. We observed the need for more research since the 5G and vertical applications continuously evolve. This review also uncovers research gaps and future research directions.
Mapping competition between domestic and distant water fishing fleets in West Africa
Authors: Issifu Ibrahim
Published: December 2023

The marine waters of West Africa are one of the most productive in the world with diverse marine fish species that support livelihoods and food security for about 6.7 million people across the region. Small-scale fisheries accounts for approximately 44% of total landed catches and 48% of the total landed value, with regional catches exceeding 1.8 million tonnes and generating over 2 billion USD per year. The domestic fishing fleet consists of about 54,000 small–scale canoes, and over 3,300 industrial vessels (~ 20% are foreign owned). This study examined the interaction between domestic and Distant Water Fishing fleets (DWF) that are predominantly from Asia and the European Union. Our results indicate that domestic and DWFs target key species in the region such as marine horse mackerels (Trachurus), yellowfin tuna (Thunnus Albacares), and Senegalese hake (Merluccius senegalensis). We found that DWFs substantially overlap with domestic fleets in local fishing grounds, which has caused vessel conflicts and may be contributing to the overexploitation of fisheries resources. For instance, our analysis suggests that DWFs operate within 90% of the surface area of the Senegalese EEZ suggesting a high level of competition with the Senegalese domestic fleet for space and resources. To mitigate the overexploitation of fish stocks in West Africa by DWF, we recommend that the region should create a regional management body using the Pacific Islands Forum Fisheries Agency as a model.

The call for implementing inhibitory methods in cancer treatment has intensified. Recently, cancer has deeply affected society, with Acute Myeloid Leukemia (AML) being identified as one of the most formidable and lethal adversaries. This research investigates the intricate interactions between vitamins A, B, C, D, E, and K and critical signaling pathways, such as NPM1, FLT3, and RUNX1, uncovering meaningful associations. Employing the precision of molecular docking with Autodock Vina 1.5.7, a thorough exploration of these interactions was carried out. The analysis entailed a detailed examination of hydrophilic and hydrophobic aspects using LigPlot, complemented by additional insights visualized through PyMol. The considerable occurrence of observed hydrophilic interactions, coupled with the noteworthy binding energy, underscores the potential of vitamin-related derivatives as promising contenders for inhibitory cancer treatments. However, the realization of this potential is contingent upon subsequent investigations, including a comprehensive exploration through RT-qPCR studies. While the study has successfully identified significant interactions, the intricate dynamics of gene expression necessitate thorough studies to attain a holistic understanding of both upregulation and downregulation. In conclusion, the revelations from this study not only set the stage for potential inhibitory treatments of AML through the strategic application of vitamin-based derivatives but also underscore the transformative capabilities of these derivatives. In future research endeavors, should vitamin interactions reveal substantial downregulation, these derivatives stand poised to spearhead innovative cancer treatments, marking a transformative era in targeted drug delivery.
