Summary: Understanding the crystallization mechanism and sintering ability of bioactive glasses is important for their application. This study investigated the crystallization and sintering properties of B12.5 borosilicate glasses containing varying amounts of magnesium and/or strontium. The results showed that the addition of magnesium and strontium facilitated sintering and densification, and the crystallization had unexpected effects on the bioactivity of the glasses.

Summary: In this study, the impact of manufacturing method, glass composition, and preincubation time on in vitro dissolution and cell response of borosilicate glasses and 3D scaffolds was investigated. It was found that the scaffolds exhibited faster dissolution compared to the bulk glass, with 3D printed scaffolds dissolving faster than burn-off scaffolds. Scaffolds made from B12.5-Mg-Sr glass composition showed slower ion release and calcium phosphate layer precipitation, indicating the stabilizing effect of Mg and Sr. Dynamic conditions resulted in lower ion releases and may be more optimal for in vitro cell growth. The preincubation time of 3 days was optimal to decrease the burst of ions that lead to cell death, and MC3T3-E1 cells survived and proliferated only in the presence of B12.5-Mg-Sr scaffolds. The porosity of the scaffolds did not significantly affect the survival of human adipose-derived stem cells (hADSCs). This study provides new information on material design, dissolution kinetics, testing conditions, and pre-incubation effects on cell behavior.

Summary: Bioactive glasses (BGs) and glass-ceramics (BGCs) are versatile biomaterials used for various medical applications including bone bonding, soft tissue repair, and drug delivery. This study aims to redefine BGs and BGCs by comparing their structure, processing, and properties with other biomaterials, enabling consideration of all current and future applications. The proposed definitions emphasize the non-equilibrium, non-crystalline nature of bioactive glasses and the presence of at least one crystalline phase in glass-ceramics, both designed to induce specific biological activity. These materials have the potential to bond with bone and soft tissues, promote regeneration, and deliver therapeutic ions or other treatments for orthopedic, dental, and wound healing purposes.

Summary: Bioactive glasses (BG) are commonly used in bone defect repair for their osteoinductivity and osteoconductivity. However, the early angiogenesis of BG may not be sufficient to support new bone formation in large-sized defects. Photobiomodulation (PBM) therapy, known for promoting early angiogenesis, may enhance the angiogenesis of BG and improve the bone repair. In this study, BG combined with PBM showed additive effects on bone regeneration, enhancing cell proliferation, gene expression, mineralization, new bone formation, and bone reconstruction.

Summary: Borate-doped silicate glasses were synthesized and investigated for tissue regeneration. The borate content affected the glass surface morphology, chemical structure, ion dissolution behavior, and fibroblast compatibility. The specific surface area of the glasses decreased with increased borate content and calcination temperature. The ion dissolution behavior of the glasses was controlled by the decrease in surface area caused by the stabilizing effect of increasing borate concentration. The proliferation ability of fibroblasts cultured with the dissolution products of the glasses improved with increased borate content in the glass composition.

Summary: This study introduced new polymer/bioactive glass composites with tailorable mechanical properties and ion release for bone regeneration and fixation applications. The degradation of the composites was influenced by the glass content rather than the glass composition, with Si-BaG accelerating polymer degradation more than P-BaG despite its higher reactivity. Both glasses dissolved through the polymer matrix with a predictable release rate of ions, with most P-BaG dissolved before 20 weeks in vitro while there was still Si-BaG left after 40 weeks.

Summary: Germanium selenide glasses aged for up to 20 years at room temperature exhibit structural relaxation as observed through Raman spectroscopy, with changes in the ratio of tetrahedral units and configurational entropy. The non-reversing enthalpy obtained by MDSC is not a reliable measure of the ability of a glass to relax.

Summary: The structure of metaluminous aluminosilicate glasses in the SiO2-Al2O3-Na2O-P2O5 system was investigated, revealing the incorporation of phosphate into the network structure. Changes in phosphate content resulted in depolymerization of the network structure, while increasing silica content had a minimal effect on network polymerization. These changes correlated with variations in glass transition temperature and spectroscopic properties.

Summary: This research focuses on developing a protocol to attach nisin, an antimicrobial peptide, to a nanotextured titanium alloy surface. The coated surface shows high surface energy, suitable for tissue integration, and releases nisin over a period longer than 1 day. The antibacterial properties were confirmed by reduced metabolic activity and viable adhered colonies of Staphylococcus aureus. This study demonstrates the potential of using chemically treated titanium surfaces coupled with nisin for bioactive and antibacterial tissue integration.

Summary: Although molecular dynamics (MD) simulation is a powerful tool for investigating the atomic-scale structures of complex materials, its reliable and accurate application to multi-component glass systems faces challenges due to limited force fields (FFs) and the complexity of chemical environments. This study demonstrates the feasibility of efficient and accurate large-scale density functional theory (DFT) calculations for multi-component glass systems. The evaluation of classical FFs based on the results of large-scale DFT calculations reveals low accuracy for non-bridging oxygen atoms, and differences in Si-O-Si angle distribution and electronic structure for X = Mg.

Summary: In this study, vanadium oxide xerogel samples were successfully synthesized through a liquid phase reaction and the interaction of films with water. The samples were thoroughly analyzed using X-ray diffraction and Raman spectroscopy, revealing the existence of two distinct phases. It was also discovered that previous misinterpretations regarding the high-pressure polymorph structure were due to the formation of a high-temperature phase. These findings highlight the potential for further refining and expanding the current structural models of vanadium oxide xerogel in future research efforts.
