Methodological Insights from Low-Vacuum SEM for Morphological Analysis of Schwann Cells on Electrospun Scaffolds

Paulina Salazar-Aguilar, Andrea Barrenechea Sánchez, Karina Godoy Sánchez, Paulina Martínez‐Rodríguez et autres

Schwann cells (SCs) are critical effectors of peripheral nerve regeneration, and their interaction with biomaterial scaffolds is a key parameter in neural tissue engineering. This pilot study described and evaluated protocols for a morphological, quantitative, and morphometric analysis of SCs seeded on …

New Insights into Surgical Techniques and Anatomical Landmarks for Tubular Scaffold Implantation in the Sciatic Nerve of Rats

Daniel Vargas-Chávez, Carlos Veuthey, Brandon Gutiérrez, María Eugenia González-Quijón et autres

Peripheral nerve injuries, especially neurotmesis, require precise repair strategies due to their severity and limited capacity for spontaneous regeneration. Nerve guidance conduits (NGCs) offer a promising alternative to autografts; however, consistent surgical techniques and anatomical references in rodent models could be enhanced. …

Five-Year Clinical Outcomes of Zygomatic Implants Combined With Patient-Specific PEEK Implants in Severely Resorbed Maxilla: A Retrospective Cohort Study

Yerko Leighton, Fernando José Días, Raphael Freitas de Souza, Eduardo Borie

To evaluate the 5-year outcomes of maxillary rehabilitation using zygomatic implants combined with patient-specific PEEK facial implants in severely resorbed edentulous ridges without labial support. A retrospective cohort (2017-2019) included 24 patients (mean age 62 ± 7.4 years). All underwent CBCT-based digital …

Modulating the Behavior of Schwann Cells with NGF Exposure Combined with Different Energy Densities of Photobiomodulation Cultured on Polyhydroxybutyrate (PHB) Scaffolds

Bryan Enoc Quidel-Necul, Paulina Martínez‐Rodríguez, Karina Godoy, Glauce Crivelaro Nascimento et autres

This study evaluated the effect of irradiation of different energy densities in low-level laser therapy (LLLT) and exogenous nerve growth factor (NGF) on Schwann cells (SCs). SCs (SCL 4.1/F7) exposed to LLLT (4 or 80 J/cm2) and NGF (25 ng/mL) were evaluated …

Effect of Ethyl-Cyanoacrylate and Platelet-Rich Fibrin on Fresh Sockets of Rabbits Subjected to Anticoagulant Therapy

Eduardo Rosas, Fernando José Días, Dimítrius Leonardo Pitol, Sergio M. Olate et autres

Objectives: There are no studies related to the use of PRF associated with cyanoacrylates in fresh post-extraction sockets. Thus, the aim of this study was to assess the effect of ethyl-cyanoacrylate combined with PRF in fresh sockets of rabbits subjected to anticoagulant …

Exploring Schwann Cell Behavior on Electrospun Polyhydroxybutyrate Scaffolds with Varied Pore Sizes and Fiber Thicknesses: Implications for Neural Tissue Engineering

María Florencia Lezcano, Paulina Martínez‐Rodríguez, Karina Godoy, Jeyson Hermosilla et autres

The placement of a polymeric electrospun scaffold is among the most promising strategies to improve nerve regeneration after critical neurotmesis. It is of great interest to investigate the effect of these structures on Schwann cells (SCs), as these cells lead nerve regeneration …
