The Importance of Electron Transfer Mechanism in Reactions of Neutral Transition Metal Atoms

Laser Chemistry, Volume 15, Issue 2-4, Page 209-220, 1995., 1995
Reaction kinetics of ground, Ti(a3F) and V(a4F), and excited, Ti(a5F) and V(a6D), states atoms with some simple molecules have been studied by a discharge‐flow tube technique. Laser‐induced fluorescence (LIF) was used to determine the concentration of the metal atoms as a function of the flow rate of the reactant molecule to obtain effective ...

Calycosin alleviates titanium particle‐induced osteolysis by modulating macrophage polarization and subsequent osteogenic differentiation

Journal of Cellular and Molecular Medicine, Volume 28, Issue 7, April 2024.
Abstract Periprosthetic osteolysis (PPO) caused by wear particles is one of the leading causes of implant failure after arthroplasty. Macrophage polarization imbalance and subsequent osteogenic inhibition play a crucial role in PPO. Calycosin (CA) is a compound with anti‐inflammatory and osteoprotective properties.
