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 ...

Bio-mechanical effects of femoral neck system versus cannulated screws on treating young patients with Pauwels type III femoral neck fractures: a finite element analysis

BMC Musculoskeletal Disorders
Introduction As a novel internal fixation for femoral neck fractures, the femoral neck system has some advantages for young Pauwels type III femoral neck fractures without clear biomechanical effects and mechanisms. Thus, the objection of the study is to

Beyond Bioactive Glass Composition: Using Morphology to Improve in Vitro and in Vivo Performance

Advanced Healthcare Materials, EarlyView.
Bioactive glasses can easily be shaped into granules, spheres, discs, fibers, or three‐dimensional scaffolds. The resulting morphology not only affects handling properties; it has a direct influence on various glass properties, including results of acellular immersion experiments or in vitro studies with cells or bacteria, but also on in vivo ...
