H2HUBB TAKEAWAY
The study reports that A H2O2-sensitive thioketal (TK) linker was then conjugated onto the surface of UCNP@TiO2 to attach a black hole quencher (BHQ), yielding the functionalized nanocomposite UCNP@TiO2-TK-BHQ.ResultsIn the presence of…
What the Researchers Studied
Source-reported study description: In this study, we developed an upconversion nanocomposite for integrated diagnosis and therapy of OA.
Source-reported study description: Upconversion nanoparticles (UCNP) were first synthesized and coated with hydrogen-producing TiO 2 to form UCNP@TiO 2 .
What the Study Found
The authors reported: Local H2 release remodels senescence microenvironment for improved repair of injured bone .
The authors reported: Molecular hydrogen protects chondrocytes from oxidative stress and indirectly alters gene expressions through reducing peroxynitrite derived from nitric oxide .
