Summary: Magnesium calcium phosphate composite bioceramic scaffolds were fabricated using 3D printing technology with Mg3(PO4)2 and β-Ca3(PO4)2 as starting materials. The porosity and compressive strength of the scaffolds could be adjusted by altering the sintering temperature and the formula of starting materials. The Ca3Mg3(PO4)4-based bioceramic scaffolds, prepared from 60 wt% Mg3(PO4)2 and 40 wt% β-Ca3(PO4)2, showed the highest compressive strength and stimulated cellular growth and osteoblastic differentiation.

Summary: The doping of Mg2+ and Fe3+ improves the mechanical properties and bone regeneration capacity of calcium phosphate ceramics. In this study, MgO-BCP, Fe2O3-BCP, and FeBCP bioceramics were prepared by stereolithography and their effects on curing behavior, mechanical properties, biodegradation, and cytocompatibility were studied. The addition of 1% Fe enhances the flexural strength of BCP, while 1% MgO promotes biodegradation and cell proliferation. Fe powder is more suitable as a dopant than Fe2O3 powder, and Fe-BCP shows higher strength and less cytotoxicity. This study demonstrates the potential of SLA 3D printed BCP bioceramics doped with MgO and Fe for bone defect repair.

Summary: The production of patient-specific bone substitutes using 3D printing is emerging as an alternative to autologous bone grafting. Material characteristics such as porosity and stiffness play a crucial role in tissue regeneration. By using hydrogel combined with biphasic calcium phosphate particles, a complex network with good mechanical properties can be obtained. Various factors, including crosslinking time and printing parameters, as well as particle size and concentration, affect the stiffness of the printed matrices. The swelling behavior and degradability of the printed structures are also dependent on the particle characteristics.

Summary: This in vitro study compared the mechanical performance of 3D printed and milled zirconia blocks under compression load, and investigated the microstructural characteristics of the 3D printed samples before and after loading. The results showed that while some 3D printed samples failed, those that did not break exhibited better modulus of elasticity and lower tendency to deformation under compression compared to the milled ones. In conclusion, milled zirconia blocks were found to be more resistant to compression forces than 3D printed ones within the limitations of this study.

Summary: Collagen is an important component of the extracellular matrix and plays a crucial role in maintaining tissue support. In fibrotic diseases, collagen is overexpressed, leading to the formation of a stiffer extracellular matrix. By using high-resolution analytical tools, it is possible to investigate the three-dimensional organization and secondary structure of collagen in fibrotic diseases, which can help identify specific markers associated with pathological conditions. In this study, a multidisciplinary approach using Phase-Contrast MicroComputed Tomography, Transmission Electron Microscopy, and Fourier Transform Infrared Imaging Spectroscopy was applied to analyze the microstructural features of collagen in leiomyoma samples and adjacent myometrium. Leiomyoma is a common gynecological disorder characterized by excessive collagen production. Additionally, the effects of omega-3 fatty acids EPA and DHA on collagen reduction were also investigated.

Summary: In a scaffold-based approach for bone tissue regeneration, trabecular geometry was controlled to balance scaffold biomechanical performances. The scaffolds with different porosities were manufactured and their mechanical and biological performances were investigated. The results showed that trabecular geometry influenced the elastic modulus, compressive strength, and cell viability of the scaffolds. Several morphometric parameters were identified as being important for the biomechanical behavior of trabecular scaffolds in tissue engineering applications.

Summary: Austenitic stainless steels used in osteosynthesis devices are prone to crevice corrosion. Studies have shown that austeno-ferritic duplex stainless steel is a suitable alternative due to its resistance to crevice corrosion and superior mechanical properties. However, the use of duplex stainless steel for biomedical applications is still under discussion due to potential harmful effects in magnetic fields.

Summary: This experimental study investigates the combined effects of hydroxyapatite concentration and elementary unit cell geometry on the biomechanical performances of additively manufactured polycaprolactone/hydroxyapatite scaffolds. The study shows that hydroxyapatite has both negative and positive effects on scaffold compaction and human mesenchymal stem cell adhesion, respectively. It also demonstrates that the unit cell geometry influences mechanical response and cell proliferation, while both hydroxyapatite concentration and unit cell geometry affect the scaffold's elastic deformation behavior and degradation rate through micro-porosity.

Summary: This study reports on a biomaterial, a silk fibroin film embedded with iron oxide superparamagnetic nanoparticles, which has potential applications as a bioactive coating in regenerative medicine. The film's properties were studied, including its structure, mechanics, and magnetism. In vitro tests on human bone marrow-derived mesenchymal stem cells cultured on the films showed that the sample with the highest nanoparticle load had the best performance in terms of cell proliferation, adhesion, and osteogenic differentiation. The findings were explained by the magneto-mechanical mechanism triggered by the applied magnetic field.
