Microbial and Enzymatic Transformation of Per- and Polyfluoroalkyl Substances (PFAS): From Defluorination and Biological Partitioning to a Separation-First Biological Treatment Framework

Per- and polyfluoroalkyl substances (PFAS) are persistent environmental pollutants. Conventional destructive technologies, such as advanced oxidation and electrochemical processes, can achieve partial or complete defluorination. However, their high energy demand, chemical inputs,...

Enhancing biodegradation of polycyclic aromatic hydrocarbons using bacterial consortia and biofilm

Abstract The release of petroleum and its constituents, such as polycyclic aromatic hydrocarbons (PAHs), into the environment poses a significant global threat due to their toxic, genotoxic, mutagenic, and/or carcinogenic properties. Using indigenous PAH-degrading bacteria to dec...

Retention and wear assessment of novel PolyEtherKetoneKetone versus traditional cobalt chromium material used in digital double crown retained removable partial dentures

BACKGROUND: Conventional removable partial dentures (RPDs) involve a process that is often susceptible to errors and demands a significant investment of time. The introduction of computer-aided design and computer-aided manufacturing (CAD/CAM) technology and materials witnessed s...

Synthesis and molecular docking of novel pyrazole, pyrimidine, and pyridine derivatives as potent antimicrobial, antibiofilm, and anticancer agents

Abstract The development of novel antimicrobial and anticancer agents remains a priority due to rising drug resistance and high systemic toxicity of current treatments. A series of novel pyrazole ( 2–6 ), pyrimidine ( 7–10 ), and pyridine/oxazinone ( 11–14 ) derivatives were synt...

Translation of Dialect in Literature: A Case Study of The Adventures of Huckleberry Finn

This qualitative research employs a comparative textual analysis to examine the challenges of translating dialect-rich literature, focusing on the Arabic translations of Mark Twain's The Adventures of Huckleberry Finn by Maher Naseem and Nasr Abdelrahman published in 1998 and 200...

Evaluating the Role of MIA3 Variant rs17465637 in Coronary Artery Disease: A Comprehensive Case–Control Analysis

Objectives: Coronary artery disease (CAD) remains a leading cause of morbidity and mortality worldwide, yet population-specific evidence regarding the contribution of MIA3 genetic variation in Middle Eastern populations remains limited. This study investigated the association of...

Ventricular Tachycardia Ablation in Nonischemic Cardiomyopathy: Is Pulsed Field Ablation the Next Paradigm Shift?

Ventricular tachycardia ablation in nonischemic cardiomyopathy remains limited by high recurrence rates despite advances in catheter-based techniques. In nonischemic cardiomyopathy, the arrhythmogenic substrate is often heterogeneous and may involve intramural or epicardial myoca...

Can Carica papaya Serve as an Adjunct to Semaglutide in Mitigating Diabetes-Induced Testicular Injury Through Modulation of Oxidative Stress, Inflammation, Apoptosis, and the miR-34c/miR-155–SIRT1/FOXO1 Axis? An Experimental and Chem-Bio-Informatics Study

Diabetes mellitus (DM) induces significant endocrine disruption and oxidative stress (OS) within the testes, resulting in impaired spermatogenesis, increased sperm abnormalities, and compromised reproductive function. This study aimed to evaluate the combined protective effects o...

Acaricidal activity of silver nanoparticles biosynthesized from unripe fruits of Solanum elaeagnifolium Cav. against Tetranychus urticae Koch

Abstract Background Tetranychus urticae Koch, is a globally significant agricultural pest. Its rapid development of resistance to conventional acaricides poses a major challenge to effective control. Recently, nanotechnology has emerged as a transformative approach in agriculture...
