This study aims to assess the potential of replacing resin-based models with PLA models in clinical settings by evaluating the mechanical properties and accuracy of MEx-printed PLA and DLP-printed resin samples. The investigated materials include pure PLA, a PLA composite containing gypsum, and a clinically approved resin material. Strength and hardness tests were conducted using custom-made samples measuring 16 × 4 × 2 mm³. Additionally, oral cavity scans were used to generate oral models for each material to assess their accuracy, trueness, and precision. The results indicated that pure PLA exhibited the highest flexural modulus (2055 ± 217.70 MPa) and compression modulus (2.40 ± 0.14 GPa). The PLA-Gypsum composite displayed the highest hardness (19.48 ± 2.12 HV1). As for the trueness of the oral models, there were no statistically significant differences between the models made from the three materials. However, the PLA-Gypsum composite demonstrated the best precision (23.84 ± 4.12 μm).

Porcine cornea has been receiving increasing attention due to its ease of obtaining, biomechanical properties similar to those of human tissue and lower antigenicity. Based on this, the objective of this study was to evaluate the biocompatibility of porcine stroma decellularized by sodium dodecyl sulfate (SDS) through interlamellar implantation in rabbit corneas. The obtained results showed that the lenticule intrastromal implantation was successfully performed and did not elicit rejection. Furthermore, the implanted stroma was able to promote an increase in the thickness of the host cornea. Microscopic analyses revealed that the tissue was well-adhered and the collagen fibrils were more aligned on its periphery.

The cytotoxicity, cell proliferation inhibition, endocytosis pathway, intracellular trafficking/localization, and autophagy behavior of the blank glycopolymer micelles and/or DOX-loaded micelles were studied in a Human Glioblastoma Carcinoma (H4) and green fluorescent protein-tagged H4-GFP-LC3 cell lines.

Notably, after treating with DOX-loaded glycopolymer micelles (or free DOX) to the H4-GFP-LC3 cells, exogenous substances-induced autophagosome accumulation was observed. The autophagy inhibitors: 3-methyladenine (3-MA) and hydroxychloroquine (HCQ) were used to monitor the autophagy behavior of H4-GFP-LC3 cells incubated with the micelles.

This approach aims to simplify treatment and improve clinical outcomes. Brinzolamide-loaded polyethylene glycol poly (lactic-co-glycolic acid) (PEG-PLGA) nanoparticles were encapsulated within a hydrogel synthesized through the crosslinking of oxidized hyaluronic acid (OHA) and carboxymethyl chitosan (CMC). In vitro studies were conducted to assess the nanoparticles’ characterization, release profile, and biocompatibility. In a steroid-induced high intraocular pressure (IOP) mouse model, the efficacy of a single subconjunctival injection in lowering IOP was evaluated. Additionally, both cellular and animal biocompatibility were assessed. The brinzolamide-loaded hydrogel system (Hydrogel@Brz) contained nanoparticles with an average diameter of 40.76 nm, exhibiting a stable size distribution and a spherical morphology. The hydrogel demonstrated excellent injectability, self-healing properties, and a porous structure conducive to nanoparticle encapsulation. In vitro release studies revealed a sustained drug release of 86% over 14 days. No cytotoxicity was observed in human primary trabecular meshwork cells (HTMCs), human Tenon’s capsule fibroblasts (HTFs), or the retinal ganglion cell line R28. In vivo, a single injection led to a prolonged IOP reduction lasting up to 21 days. No signs of drug toxicity were detected in ocular tissue sections, transverse optic nerve sections under transmission electron microscopy, or pathology slides of various organs.

In a prospective, randomized controlled trial, we compared TKA outcomes using MC-PMMA versus traditional PMMA (T-PMMA) in 34 patients with bilateral late-stage osteoarthritis. Evaluated parameters included patient-reported outcome measures (PROMs), knee range of motion, pain scores, complications, and radiographic evaluations over a 45.8-month follow-up.

Radiographic evaluations revealed no differences in postoperative Hip-Knee-Ankle (HKA) angle, anatomical axis angle, or radiolucent lines. Complication rates were similar, with no infections, aseptic loosening, peri-prosthetic fractures, or revisions.
