Mesoporous Bioactive Glasses: A Powerful Tool in Tissue Engineering and Drug Delivery

Advanced Healthcare Materials, EarlyView.
This work is a comprehensive revision of bioactive glasses (BGs), pioneered by Prof. L.L. Hench, which are key in bone repair and regenerative medicine. Sol–gel methods and mesoporous designs enhanced their bioactivity, ions, and drug delivery. BGs now support gene therapy and 3D‐printed scaffolds, enabling personalized, multifunctional treatments in ...

ISO spectroscopy of disks around Herbig Ae/Be stars

, 2004
We have investigated the infrared spectra of all 46 Herbig Ae/Be stars for which spectroscopic data is available in the ISO data archive. Our quantitative analysis of these spectra focusses on the emission bands linked to polycyclic aromatic hydrocarbons

Granular Hydrogels as Modular Biomaterials: From Structural Design to Biological Responses

Advanced Healthcare Materials, EarlyView.
Granular hydrogels are now emerging as promising biomaterials due to their inherent microporousity, injectability, and modularity. They have shown improvements in cell viability and migration, cellular/tissue infiltration, host tissue integration, mitigated foreign body response, and tissue regeneration.

Crystal structures of Ca4+xY3–xSi7O15+xN5–x(0 ≤ x ≤ 1) comprising of an isolated [Si7(O,N)19] unit

Acta Crystallographica Section E: Crystallographic Communications, 2019
Single crystals of the solid solution series Ca4+xY3–xSi7O15+xN5–x were obtained by a solid-state reaction method using a flux for x = 0, 0.5 and 1, resulting in Ca4Y3Si7O15N5 (tetracalcium triyttrium heptasilicon oxynitride), Ca4.5Y2.5Si7O15.5N4.5 and ...

Preparation of Bifunctional Orthosilicophosphate MgO‐CaO‐ZnO‐P2O5‐SiO2 Glasses: in vitro Evaluation of Antibacterial Activity and Osteoblast Gene Expression Behavior

Advanced Healthcare Materials, EarlyView.
Bifunctional ZnO‐containing orthosilicophosphate glasses (SPGs) composed mainly of orthotetrahedral groups with the unique glass network structure without long‐chain units are prepared via melt‐quenching. The glasses exhibit excellent antibacterial activity and upregulate the expression of osteogenic markers by releasing inorganic ions.

Borate‐Ion‐Stimulated Macrophages Promote Osteogenic Differentiation of Mesenchymal Stem Cells

Advanced Healthcare Materials, EarlyView.
The immune responses of mouse macrophages stimulated by borate ions promote the osteogenic differentiation and mineralization of mouse bone marrow–derived mesenchymal stem cells in an ion‐dose‐dependent manner by providing cytokines, including BMP‐2.
