the overexpression of the ABCB1 gene.

background:

Breast cancer remains a leading cause of cancer-related deaths among women, primarily attributed to the formidable challenge of multidrug resistance, often driven by the overexpression of the ABCB1 gene.

Objective:

This study aimed to assess the synergistic effects of siRNA, doxorubicin, and vinorelbine
on ABCB1 gene expression and cell viability in doxorubicin-resistant MCF-7/ADR
breast cancer cells, with siRNA targeting ABCB1 to reduce its expression and doxorubicin/ vinorelbine
to eradicate cancer cells.

objective:

This study aimed to assess the synergistic effects of siRNA, doxorubicin, and vinorelbine on ABCB1 gene expression and cell viability in doxorubicin-resistant MCF-7/ADR breast cancer cells, with siRNA targeting ABCB1 to reduce its expression and doxorubicin/vinorelbine to eradicate cancer cells.

Methods:

Our methodology involved culturing MCF-7 and MCF-7/ADR cells in standard cell
culture conditions. The synthesized siRNA sequences transfected cells with siRNA at final concentrations
of 10, 20, and 30 nM and assessed cell viability using the MTT assay was performed.
Real-time PCR was employed to quantify ABCB1 mRNA expression levels.

Results:

Results indicated that MCF-7/ADR cells exhibited substantial resistance to vinorelbine
and doxorubicin compared to MCF-7 cells, displaying resistance at 12.50 μM and 25.00 μM for
vinorelbine and 6.25 μM and 25.00 μM for doxorubicin. Remarkably, siRNA treatment effectively
reversed drug resistance in MCF-7/ADR cells across all concentrations of vinorelbine and
doxorubicin tested. When combined, siRNA, doxorubicin, and vinorelbine yielded a significantly
greater reduction in cell viability compared to individual drug treatments, particularly at a 20
μM siRNA concentration. This combination therapy also significantly suppressed ABCB1 gene
expression by a factor of 41.48 in MCF-7 cells relative to MCF-7/ADR cells.

Conclusion:

these findings suggest that combining siRNA, doxorubicin, and vinorelbine holds
promise as a therapeutic strategy to overcome ABCB1-mediated multidrug resistance in breast
cancer. Further investigations and clinical trials are warranted to evaluate its clinical efficacy
rigorously.
Anthocyanin-Mediated Autophagy in Hepatocellular Carcinoma: Gene Associations and Prognostic Implications
Authors: Du Juan , Shen Enhua
Published: April 2024

Background:

Hepatocellular carcinoma (HCC) is a globally prevalent malignancy
accompanied by high incidence, poor outcomes, and high mortality. Anthocyanins can inhibit
tumor proliferation, migration, invasion, and promote apoptosis. Moreover, autophagy-related
genes (ARGs) may play vital roles in HCC progression. This study aimed to decipher the mechanisms
through which anthocyanins influence HCC via ARGs and to establish a novel prognostic
model.

Methods:

Based on data from public databases, differential analysis and the Venn algorithm
were employed to detect intersecting genes among differentially expressed genes (DEGs), anthocyanin-
related targets, and ARGs. Consensus clustering was implemented to delineate molecular
subtypes of HCC. The prognostic model was developed by Cox regression analyses.
CIBIRSORT was engaged to assess the immune cell infiltration. Kaplan-Meier (KM) analysis
and receiver operating characteristic (ROC) curve were utilized to evaluate the predictive efficiency
of the prognostic signature.

Results:

A total of 36 intersecting genes were identified from overlapping 1524 ARGs, 537 anthocyanin-
related targets, and 5247 DEGs. Consensus clustering determined three molecular
subtypes (cluster 1, cluster 2, and cluster 3). Cluster 1 showed worse outcomes and remarkably
higher abundances of plasma cells and T follicular helper cells. Furthermore, four prognostic
signatures [KDR (Kinase insert domain receptor), BAK1 (BCL2 antagonist/killer 1), HDAC1
(Histone deacetylase 1), and CDK2 (Cyclin-dependent kinase 2)] were identified and showing
substantial predictive efficacy.

Conclusion:

This investigation identified three molecular subtypes of HCC patients and proposed
a promising prognostic signature comprising KDR, BAK1, HDAC1, and CDK2, which
could supply further robust evidence for additional clinical and functional studies.

Published: April 2024

Introduction:

The catalytic activity of metallic nanomaterials depends on their surface morphology. A widely known method is the laser synthesis of metal nanostructures by depositing on dielectric surfaces from aqueous solutions containing metal complexes. The article analyzes the factors that favor the production of conductive, catalytic, and sensory-active deposits by laser method. It is shown that the two main factors is the presence of a large number of charged defects on heterophase surfaces and the structure of metal-containing complexes in solution. This is typical for mono- and bimetallic alloys, the components of which interact with the laser beams according to the autocatalytic type. Using the example of laser deposition from solutions of Co, Ni, Fe, Zn, and Ag salts with homo- and heterophase dielectrics, the sensory and catalytic properties of the deposits are compared by impedance spectroscopy and voltammetry. It has been shown that heterophase precipitation significantly enhances the catalysis response.

Background:

It is known that the highest catalytic activity exhibits nanostructured and highly porous materials with a large specific surface area and materials containing surface heterogeneity in the form of charged acid-base centers. Such materials are necessary for the creation of new catalysts for organic synthesis and for the creation of new sensor materials for enzyme-free microbiosensors. Active development of new methods for the synthesis of such materials is underway. But not all of them give the expected result.

Methods:

Laser synthesis methods have the best prospects, including the method of laser-induced metal deposition. This is the laser synthesis of metal nanostructures by depositing dielectric surfaces from aqueous solutions containing metal complexes.

Results:

Аrticle analyzes the factors that favor the production of conductive, catalytic, and sensory-active deposits by laser method. It is shown that the two main factors are the presence of a large number of charged defects on heterophase surfaces and the structure of a metal-contained complex in solution. This is typical for mono- and bimetallic alloys, the components of which interact with the laser beam according to the autocatalytic type. Using the example of laser deposition from solutions of Co, Ni, Fe, Zn, and Ag salts with homo- and heterophase dielectrics, the sensory and catalytic properties of the deposits are compared by impedance spectroscopy and voltammetry.

Conclusion:

It has been shown that heterophase precipitation significantly enhances the catalysis response. It is shown that the laser deposition reaction has an autocatalytic mechanism in a dynamic mode. The results of autocatalysis can be used in a stationary mode to create a microbiosensor for glucose, as well as to create a technology for laser refining rare metals and hydrogen energy in a dynamic mode.

Cement Dosage and Compressive Strength Correlation in Rammed Earth Walls: a Case Study
Authors: Ariza Flores Victor Andre , Ortega Hilario Elizabeth Fiorella
Published: April 2024

In this study, we investigated the correlation and development of a linear regression model between the variables "added cement" and "compressive strength of rammed earth walls" constructed with aggregates obtained from Colpa Alta, Huánuco, Peru through bivariate analysis and multivariate data analysis. This analysis was motivated by the increasing difficulty for the local population to build confined masonry housing due to the increase in the prices of building materials brought on by the COVID-19 pandemic. In this context, rammed earth walls offer a more affordable alternative to the traditional system, although it is necessary to improve their structural capacity. 60 samples of aggregates were collected in situ, following the Peruvian Technical Standard E-080. Subsequently, they were divided into four groups of 15 samples each, where 5%, 10% and 15% of the aggregate were replaced by cement. Compressive strength tests were performed, and the results were analysed using statistical techniques. The findings revealed a significant increase in compressive strength in samples containing cement compared to conventional rammed earth blocks. It was obtained that there is a strong correlation between the variable "added cement" and "compressive strength of rammed earth walls".  The linear regression model quantitatively explained the influence of cement on compressive strength.
Rolling the DICE (Design, Interpret, Compute, Estimate): Interactive Learning of Biostatistics With Simulations
Authors: Thiesmeier Robert , Orsini Nicola
Published: April 2024

Despite the increasing relevance of statistics in health sciences, teaching styles in higher education are remarkably similar across disciplines: lectures covering the theory and methods, followed by application and computer exercises in given data sets. This often leads to challenges for students in comprehending fundamental statistical concepts essential for medical research. To address these challenges, we propose an engaging learning approach—DICE (design, interpret, compute, estimate)—aimed at enhancing the learning experience of statistics in public health and epidemiology. In introducing DICE, we guide readers through a practical example. Students will work in small groups to plan, generate, analyze, interpret, and communicate their own scientific investigation with simulations. With a focus on fundamental statistical concepts such as sampling variability, error probabilities, and the construction of statistical models, DICE offers a promising approach to learning how to combine substantive medical knowledge and statistical concepts. The materials in this paper, including the computer code, can be readily used as a hands-on tool for both teachers and students.

Authors: Mahsusi Mahsusi , Hudaa Syihaabul , Nuryani Nuryani , Fahmi Mustofa , Tsurayya Ghina , Iqhrammullah Muhammad
Published: April 2024

Background

During health crises such as the COVID-19 pandemic, shortages of health care workers often occur. Recruiting students as volunteers could be an option, but it is uncertain whether the idea is well-accepted.

Objective

This study aims to estimate the global rate of willingness to volunteer among medical and health students in response to the COVID-19 pandemic.

Methods

A systematic search was conducted on PubMed, Embase, Scopus, and Google Scholar for studies reporting the number of health students willing to volunteer during COVID-19 from 2019 to November 17, 2023. The meta-analysis was performed using a restricted maximum-likelihood model with logit transformation.

Results

A total of 21 studies involving 26,056 health students were included in the meta-analysis. The pooled estimate of the willingness-to-volunteer rate among health students across multiple countries was 66.13%, with an I2 of 98.99% and P value of heterogeneity (P-Het)<.001. Removing a study with the highest influence led to the rate being 64.34%. Our stratified analyses indicated that those with older age, being first-year students, and being female were more willing to volunteer (P<.001). From highest to lowest, the rates were 77.38%, 77.03%, 65.48%, 64.11%, 62.71%, and 55.23% in Africa, Western Europe, East and Southeast Asia, Middle East, and Eastern Europe, respectively. Because of the high heterogeneity, the evidence from this study has moderate strength.

Conclusions

The majority of students are willing to volunteer during COVID-19, suggesting that volunteer recruitment is well-accepted.

Utilization of Form-Stable Paraffin/Nano-Silica Phase Change Materials for Thermal Energy Storage Enhancement in Mortar
Authors: Islam Md. Rasidul , Li Xiangyu
Published: April 2024

This research explores the utilization of form-stable paraffin/nano-silica phase change materials (PCMs) to improve thermal energy storage in mortar. The composite PCM, comprising paraffin enclosed within a nano-silica framework, offers enhanced stability and compatibility with mortar compared to traditional PCM systems. Experimental investigations were conducted to assess the thermal performance and mechanical properties of mortar specimens incorporating varying concentrations of form-stable PCM. Thermal conductivity, heat storage capacity, and mechanical strength were analysed through thermal cycling tests and mechanical testing methods to understand the impact of PCM content. Results demonstrate that integrating form-stable paraffin and nano-silica PCMs enhances thermal energy storage capabilities in mortar while minimally affecting mechanical strength. Moreover, the nano-silica matrix facilitates better dispersion and adhesion of paraffin particles within the mortar matrix, addressing concerns related to PCM leakage and separation during hydration. This study underscores the viability and efficacy of employing form-stable paraffin and nano-silica PCMs to enhance thermal energy storage in mortar, offering a promising avenue for sustainable and energy-efficient construction materials.
Reuse of Greywater and its Role in the Sustainability of Water Resources – A Study in Saudi Arabia
Authors: Al-Saud Anbarah Khamis B.
Published: April 2024

Reuse of greywater has become one of the proposed solutions worldwide to support water resources; that are subject to depletion in desert areas such as Saudi Arabia, where rainfall is scarce, suffering growing water demand for municipal and agricultural purposes, and the sustainability of groundwater resources on the other. In Saudi Arabia greywater represents nearly 55-74% of the water consumed in the buildings; so this study aimed to answer the following question: According to ministerial order No. 228 of 29 August 1426 AH, which stipulates that greywater should be reused and that two wastewater recycling systems should be implemented in the development of specifications and plans for the construction of new installations in the sectors concerned; Are there any indicators which prove the implementation of this ministerial decision? What is the evidence for this application? The reuse of treated greywater depends on the natural, chemical, and physical characteristics of the amount of biological consumption of oxygen (BOD5), total suspended solids (TSS), and the chemical oxygen demand (COD). The study concluded that some of the general natural characteristics of water are similar in value to those of high-income and low-income countries. The results show a continuous increase in water consumed through the study period within the urban and agricultural sectors, of Saudi Arabia into global support for the conservation of natural resources.

TREATMENT OF THE POETIC TEXT OF CRNJANSKI AND CHARACTERISTICS OF THE HARMONIC LANGUAGE IN THE SUMATRA SONG BY SVETISLAV BOŽIĆ
Authors: Milenkovic Marko , Milošević Ivana
Published: April 2024

The inspiration of Svetislav Božić by the literary works of Miloš Crnjanski, which dates from 1989 to the present day, resulted in numerous works by which we can trace the connection between the two artists, as well as the style, aesthetics, artistic fantasy and creative credo of the composer. The subject of our research is a song for female voice and piano – Sumatra, the key poem of the cycle on which Crnjanski conceived an entire poetic-theoretical concept of the avant-garde literary program – Sumatraism. The work follows Božić's "librettistic" work on the poetic template whose continuity and integrity are retained by the composer using minimal interventions, additionally emphasizing the value of Sumatra, as well as other poems. Božić's creative path starts from a complete analysis of the poetic text, positioning the main points of emotional experience, the atmosphere of sensory images and the "space of happiness", and musicalisation of the literary source without transforming it. In the architecture of Sumatra, attention is drawn to the diversity of the harmonic palette: from consonant modal chords in triadand expressive seventh-chord forms to the particularly significant role of colouristic nuances of the minor ninth-chord in sporadic gradation to the eleventh chord and the sonority of the whole-scale feature on the stylistic basis of Debussy – Scriabin, but always in the strict function of musical dramaturgy with the preservation of tonality. In this context, the stylistic corridor of Sumatra follows a wide arc of intertwining of Romanticism and Impressionism origin with a national idiom of a wide range of means, radiating precious, complex meanings. Despite the accumulation of heritage of European music that belongs to him in terms of artistic freedom, Božić does not fall under its influence, since the dominant principle of his expression is created by national indigeneity in the use of modernized elements of national tradition, sometimes discreetly interwoven, thus confirming that "under other conditions, in another time, does the same thing as Mokranjac".
La ética como reguladora de los procesos de actuación profesional del Trabajo Social
Authors: Vélez Restrepo Olga Lucía
Published: April 2024

El articulo plantea la reflexión sobre la ética como reguladora de los procesos de actuación profesional en el marco del Trabajo Social contemporáneo, desvinculada de los valores tradicionales de corte moral o religioso y en el contexto de un quehacer profesional enfrentado a la conflictividad político social como constitutiva de las sociedades actuales y cuyos descentramientos arrastran la configuración de nuevos ethos socioculturales. Cuando las condiciones vinculantes que conectan a la profesión con el ideal tradicional del "buen profesional" (o profesional virtuoso cuyas actuaciones están regidas por mandatos externos y valores morales altruistas o caritativos de carácter misional) se quiebran o desdibujan, cobra fuerza otra ética: la argumentativa, regida por la razón, que se sitúa en el terreno de la incertidumbre y cuyas condiciones de existencia y posibilidad atañen a un tiempo y espacio determinado, siendo por lo tanto histórica y social. Esta nueva ética emerge constituyéndose en una apuesta colectiva desde la cual se orienta y habilita a la profesión para representar los intereses colectivos y aportar a la democratización de la vida social, de una manera tal que las instancias concretas que conforman el denominado universo de la actuación profesional se conviertan en espacios de afirmación de la ciudadanía y defensa de lo público. Este debate sobre los dilemas éticos que enfrentan los procesos de actuación del Trabajo Social está soportado además en la consideración sobre la pertinencia actual de la profesión y en su futura proyección, en el marco de una responsabilidad social orientada hacia el análisis crítico de los impactos que los procesos de conocimiento y de acción suelen generar.
La intervención en lo social como dispositivo. Una mirada desde los escenarios actuales
Authors: Carballeda Alfredo Juan Manuel
Published: April 2024

Desde el presente trabajo se desarrollan diferentes aspectos de la complejidad actual de la intervención social, cambios en los escenarios de ésta y las transformaciones institucionales desde una perspectiva centrada en la singularidad americana atravesada por una serie de elementos contextuales. De este modo, la intervención en lo social requiere elementos de análisis profundos que den cuenta de sus nuevas posibilidades. Se aborda a partir de la utilización de la noción de dispositivo desarrollada por Michel Foucault como forma de aproximación a esa complejidad, y desde una perspectiva que permite pensar la intervención en lo social no sólo como la continuidad de una práctica punitiva, sino también como una posibilidad de resistencia o construcción de libertad. Al mismo tiempo se trabajan aspectos relacionados con la tensión entre emancipación y libertad que atraviesa las prácticas que se fundan en la Modernidad. Por otra parte, el trabajo hace referencia a las posibilidades de elaboración de una epistemología de la intervención social.
La sistematización desde una mirada interpretativa: Propuesta metodológica
Authors: Zavala caudillo Aurora
Published: April 2024

El artículo se sitúa en una postura del Trabajo social contemporáneo desde la perspectiva teórica interpretativa, donde los sujetos son capaces de construir, mantener y cuestionar determinadas estructuras. Por ello, Trabajo Social se inscribe desde este paradigma a generar con y desde los sujetos propuestas de acción en una determinada realidad social. El interés por reflexionar la práctica profesional se centra en mirar la sistematización/recuperación de la experiencia en Trabajo Social como un proceso que permite la reflexión crítica a partir de la reconstrucción la experiencia de la práctica; de elementos tanto objetivos como subjetivos. Planteo las aportaciones, así como los desafíos pendientes para nuestra disciplina con el fin de contribuir y postular un acercamiento a la propuesta metodológica de sistematización desde esta perspectiva teórica.
Yatrogénesis social, isomorfismo de equívocos en el diagnóstico comunitario II
Authors: Velasco Vázquez Manuel , Martínez Sierra Pedro Daniel
Published: April 2024

Se presenta la segunda parte de un artículo publicado en la edición número 20 de la Revista de la Escuela Nacional de Trabajo Social, ahora con los ocho equívocos restantes en la realización del diagnóstico comunitario, entre los que destacan: parcelado; naturalización-fatalización; etapista y mecánico; racionalidad instrumental; “error fundamental” y “ceguera profesional”, y otros. Tomando como isomorfismo a la yatrogénesis, propuesta de Ivan Ilich, que debate sobre el desempeño de profesionales como caso aplicado a Trabajo Social, se retoman aspectos antes no abordados para continuar con la observación de las afectaciones y sus consecuencias, con la intención de reconocer las principales confusiones, imprecisiones, ambigüedades y contradicciones implicadas como autocrítica, que ayude a realizaciones diagnósticas más pertinentes y definir estrategias de intervención basadas en un conocimiento fundamentado.
Formación profesional, identidad y Trabajo Social
Authors: Yañez Pereira Víctor R.
Published: April 2024

El artículo parte de la premisa de que la realidad del Trabajo Social no sólo supone un acto de presencia en la conciencia histórica, sino de su capacidad de acontecer, es decir, de hacer emerger su identidad como una disciplina relativamente autónoma y auténticamente creadora. Esto, reconociendo que la noción de identidad comporta esa sartreana referencia de elección sobre el sí mismo, emanada en la autoconciencia de nuestra distinción por diferencia con lo que no somos nosotros, es decir, con otras profesiones y disciplinas, así como con nuestros entornos. Es una cualidad del ser que está-en-el-mundo pues, como nos ha mostrado Lévinas (2000), la pasión por lo que nos es singular a nosotros mismos no es otra cosa que la diferencia que constituye la relación entre el “yo” de la identidad propia y la alteridad de lo “otro”.
La relación migración y Trabajo Social en Honduras
Authors: Hernández Rodríguez Ana Corina
Published: April 2024

La migración en Honduras es un proceso configurado en distintos matices, y en los últimos años observa los impactos negativos en los aspectos más sensibles del ser humano en tanto se violenta lo más sagrado de la dignidad de las personas. La población fue sometida por factores económicos, políticos, sociales y culturales a corrientes migratorias, dejando atrás largos años de esfuerzo por construir un patrimonio, pero las condiciones de pobreza crónica del país lo impiden y en la perspectiva de ejercer un derecho humano, se aventuran a ser parte del fenómeno migratorio donde dependen de la suerte que les depare el camino que eligen. Hace dos décadas, si se toma el Mitch como detonante del fenómeno migratorio (1998-2019), gran parte de la población vive en situación de inestabilidad dado que salir del seno del hogar ha significado desestructurar la familia como organización más preciada para construir una sociedad saludable. Hoy día la familia aparece desfigurada, ambivalente, en el fenómeno migratorio se le coloca como expulsora de miembros por los niveles de desintegración y violencia en su interior; por otro lado, es motivo de migración los parientes que están en el país de destino donde se pretende migrar con fines de reunificación familiar.

Authors: Aguilar Medina José Iñigo
Published: April 2024

Aunque el sentido común ha visto una relación entre afectos y salud física, la medicina no siempre lohabía avalado. Sin embargo, los problemas afectivos en la familia son causantes de enfermedad portranslocación bacteriana. Para conocer la proporción de personas que pudieran estar afectadas en la ZonaMetropolitana de la Ciudad de México, se analiza el resultado de un cuestionario aplicado a 667 adultos.Se parte del supuesto de que, según el grupo de edad y el tipo de rechazo que expresan a su familia, pudieranestar pasando por un conflicto afectivo que incide en su salud. Se constata que cerca de la quintaparte de los entrevistados manifiesta dicha situación. Se concluye que como medida de salud públicaes necesario capacitar a las familias en la comunicación no violenta, en la mediación y en la resoluciónpacífica de los conflictos familiares.

Charles Lauth: dyes and other compounds
Authors: Wisniak Jaime
Published: April 2024

Charles Lauth (1836-1913) was a French chemist who worked most of his life developing new dyes and different porcelains and ceramics. To him, we owe the synthesis of the aniline dyes’ methyl violet (Paris violet), methyl green, aniline black, and Lauth’s violet (thionine), as well as the best methods for applying them to different kinds of textiles. Together with Edouard Grimaux, they developed methods for producing aromatic aldehydes, which led to the synthesis of the artificial essence bitter almond.

Aperfeiçoamento sustentável no processo de ensino-aprendizagem do exame químico provisório de cocaína
Authors: Da Silva Stelato Ederson , Santos Avelar Kátia Eliane , Indio do Brasil da Costa Vanessa
Published: April 2024

O presente artigo, que se trata de uma revisão narrativa da literatura, focou no aperfeiçoamento do processo de ensino-aprendizagem do exame químico provisório de cocaína, orientando a abordagem de docentes e qualificando os discentes de todos os níveis, principalmente, em cursos de formação técnica profissional das academias de polícia, estabelecendo a triagem de métodos sustentáveis tanto no âmbito da justiça quanto na esfera ambiental do citado exame, tendo os seguintes critérios estabelecidos: sensibilidade, seletividade, tempo de execução, registro fotográfico e redução do impacto ambiental. Com base na análise teórica, os métodos mais sustentáveis foram: o teste de Scott e cromatografia em camada delgada (CCD) —principalmente pela questão da seletividade—  tendo o CCD como um teste de resultado mais genuíno, embora varie conforme sistema solvente utilizado; e o imunocromatográfico que se destaca especialmente por contribuir com a redução do impacto ambiental, porém, como só foi constatado apenas um artigo testando a eficácia desse método para esse fim, fica ainda a dúvida de sua eficiência na questão da seletividade.
Prediction of Superplasticizers Demand in Cement Based Mortars Using Artificial Intelligence
Authors: Begani Jyotsna
Published: April 2024

Abstract: It is anticipated that global cement based mortars production is set to achieve an annual growth rate of 5.1% for the years to come. An estimated 2 to 3% of the world's yearly energy use and 9 to 10% of industrial water are used by the concrete industry. It is this ever growing need of water that can be a problem for the forthcoming generations which is why nowadays superplasticizers are used highly in the construction field, these are water reducing admixtures that are capable of reducing water content hence lowering the water cement ratio without compromising the workability of end products.

Authors: Dongre Assistant Prof. P. R.
Published: April 2024

Abstract: In the rapidly evolving digital era, ensuring the security and integrity of data has become a critical priority, particularly with the widespread proliferation of sensitive information across diverse digital platforms. While traditional encryption techniques have demonstrated efficacy, they often encounter challenges such as data format alterations and potential disruptions to existing systems. To surmount these hurdles, this paper proposes an innovative encryption paradigm that amalgamates Advanced Encryption Standard (AES), eXclusive OR (XOR) operation, and a tailored translation methodology meticulously crafted to uphold data format fidelity. This novel approach not only streamlines database modifications but also fortifies security measures. Through a rigorous comparative analysis with extant encryption methodologies, the efficacy and security advantages of the proposed framework are underscored. By seamlessly integrating cryptographic principles and AES, the envisioned solution ensures data confidentiality while preserving database performance and structure integrity, thus furnishing a robust framework for safeguarding sensitive information in today's dynamic digital milieu.
HyperFusion: Combating Phishing Attacks through URL, Hyperlink, and User Behavior Analysis
Authors: Komaraneni Adityaram
Published: April 2024

Abstract: Phishing attacks remain a persistent threat in cyberspace, demanding innovative solutions for timely detection. In this paper, HyperFusion, a pioneering approach that combines machine learning with user behavior analysis, is introduced to enhance the real-time identification of phishing websites. By integrating features derived from URL and hyperlink characteristics with dynamic user interaction patterns, HyperFusion achieves unprecedented accuracy without reliance on thirdparty systems. Traditional anti-phishing methods often falter against zero-hour attacks or novel phishing websites, underscoring the need for novel strategies. The methodology addresses this challenge by leveraging user behavior data alongside client-side information, thereby eliminating external dependencies and fortifying defense mechanisms. Additionally, a tailored dataset for rigorous experimentation is presented, facilitating a comprehensive evaluation of the approach. Experimental results demonstrate HyperFusion's superior efficacy, boasting a remarkable detection accuracy of 99.37% with the XG Boost technique.
