3D-Printed PCL-Based Scaffolds with High Nanosized Synthetic Smectic Clay Content: Fabrication, Mechanical Properties, and Biological Evaluation for Bone Tissue Engineering.
Int J Nanomedicine
January 2025
Interdisciplinary Laboratory for Advanced Materials (LIMAV), Materials Science and Engineering Graduate Program (PPGCM), Federal University of Piauí (UFPI), Teresina, PI, Brazil.
Background: The 3D printing of macro- and mesoporous biomimetic grafts composed of polycaprolactone (PCL) infused with nanosized synthetic smectic clay is a promising innovation in biomaterials for bone tissue engineering (BTE). The main challenge lies in achieving a uniform distribution of nanoceramics across low to high concentrations within the polymer matrix while preserving mechanical properties and biological performance essential for successful osseointegration.
Methods: This study utilized 3D printing to fabricate PCL scaffolds enriched with nanosized synthetic smectic clay (LAP) to evaluate its effects on structural, chemical, thermal, mechanical, and degradative properties, with a focus on in vitro biological performance and non-toxicity.
Elastic cartilage properties of the tip of the vocal process of the arytenoid cartilage.
Laryngoscope Investig Otolaryngol
February 2025
Objectives: This study aimed to investigate the histological and ultrastructural features of the elastic cartilage at the tip of the vocal process in the arytenoid cartilage, which is essential for laryngeal biomechanics.
Methods: Five larynges, including the vocal folds and epiglottis, were examined using transmission electron microscopy. The elastic cartilage at the tip of the vocal process was compared to the epiglottic cartilage within the same larynx to elucidate structural differences.

Faculty of Dentistry, Department of Prosthodontics, Çukurova University, Adana, Turkey.
The main challenges to the widespread clinical application of three-dimensional (3D)-printed customized trays include cost and time limitations. This study examined how changing the internal structure of 3D-printed materials used for customized trays affects flexural strength (FS), flexural modulus (FM), manufacturing time, and material weight. Specimens (64 × 10 × 3.
