Abstract During aging and after traumatic injuries, cartilage bone cells are exposed to various pathophysiologic mediators, including reactive oxygen species (ROS), damage-associated molecular patterns, proinflammatory cytokines. This detrimental environment triggers cellular stress subsequent dysfunction, which not only contributes the development of associated diseases, that is, osteoporosis osteoarthritis, but also impairs regenerative processes. To counter ROS-mediated reduce overall tissue damage, possess diverse defense mechanisms. However, antioxidative capacities limited thus ROS accumulation can lead aberrant cell fate decisions, have adverse effects on homeostasis. In this narrative review, we address oxidative as a major driver processes in bone, senescence, misdirected differentiation, death, mitochondrial impaired mitophagy by illustrating consequences homeostasis regeneration. Moreover, elaborate mechanisms, with particular focus response mitophagy, briefly discuss respective therapeutic strategies improve protection.

Periodontitis is a chronic inflammatory disease caused by plaque that destroys the alveolar bone tissues, resulting in tooth loss. Poor eradication of pathogenic microorganisms, persistent malignant inflammation and impaired osteo-/angiogenesis are currently primary challenges to control progression rebuild damaged bone. However, existing treatments for periodontitis fail comprehensively address these issues. Herein, an injectable composite hydrogel (SFD/CS/ZIF-8@QCT) encapsulating quercetin-modified zeolitic imidazolate framework-8 (ZIF-8@QCT) developed. This possesses thermo-sensitive adhesive properties, which can provide excellent flowability post-injection stability, resist oral fluid washout as well achieve effective tissue adhesion. Inspirationally, it observed SFD/CS/ZIF-8@QCT exhibits rapid localized hemostatic effect following implantation, then virtue sustained release zinc ions quercetin exerts collective functions including antibacterial, immunomodulation, pro-osteo-/angiogenesis pro-recruitment, ultimately facilitating regeneration.
