Upcycling Textile Waste into Anionic and Cationic Cellulose Nanofibrils and Their Assembly into 2D and 3D Materials.

Extracting high-performance nanomaterials from waste presents a promising avenue for valorization. This study presents two methods for extracting cellulose nanofibrils (CNFs) from discarded textiles. Post-consumer cotton fabrics are chemically treated through either cationization with (2,3-epoxypropyl)trimethylammonium chloride or TEMPO/NaBr-catalyzed oxidation, followed by fibrillation to produce Cat-CNFs and TO-CNFs, respectively.

Cardiac Computed Tomography as a Method of Diagnosing the Type of Cardiac Tumor-Example of Interatrial Septal Lipoma Filling the Right Atrium.

Cardiac tumors present substantial diagnostic challenges due to their diverse manifestations and similarity to other cardiac pathologies. Cardiac lipomas are rare tumors that originate from adipose cells and can develop in any location within the heart. Cardiac lipomas account for 2.

Student access patterns for an online clinical skills procedural video library.

Clinical Relevance: Clinical skills training is essential in optometry curricula to develop core graduate entry competencies, including self-directed learning to facilitate life-long learning. Efficient and efficacious approaches are required to optimise student and educator time and resources.

Background: A video library of optometric clinical skills was created in 2012 to support self-directed student learning and face-to-face training.

Static reanimation of the paralyzed face using non-absorbable polypropylene mesh.

<br><b>Introduction:</b> There are 2 methods for correcting facial deformities resulting from facial nerve paralysis - dynamic and static. Although dynamic methods are the standard approach in selected patient groups, static facial suspension using synthetic material provides a minimally invasive alternative for those who do not qualify for them.</br> <br><b>Aim:<b> Presenting experiences with the use of non-absorbable polypropylene mesh in the Department of Plastic Surgery in Polanica-Zdrój and reviewing the literature related to static facial reanimation methods.

GPT-4o vs. Human Candidates: Performance Analysis in the Polish Final Dentistry Examination.

Background This study aims to evaluate the performance of OpenAI's GPT-4o in the Polish Final Dentistry Examination (LDEK) and compare it with human candidates' results. The LDEK is a standardized test essential for dental graduates in Poland to obtain their professional license. With artificial intelligence (AI) becoming increasingly integrated into medical and dental education, it is important to assess AI's capabilities in such high-stakes examinations.
