Reduction of Wear Volume from Accelerated Aged UHMWPE Knee Components by the Addition of Vitamin E
Journal of Biomechanical Science and Engineering, 2009 Accelerated ageing was conducted on UHMWPE with and without vitamin E (D, L-α tocopherol, VE). Wear performance was investigated using a knee simulator and wear debris was analysed.

Efficacy of Etanercept for Wear Debris-Induced Osteolysis [PDF]
Journal of Bone and Mineral Research, 2001 Abstract A major limitation of total joint arthroplasty is that up to 20% of patients require revision surgery to correct prosthetic loosening. Aseptic loosening is believed to result from the phagocytosis of wear debris particles by macrophages, which secrete proinflammatory cytokines that stimulate osteolysis.

Advanced Science, EarlyView.This study utilized alloy micro‐galvanic coupling design to regulate the release of essential elements, thereby programming immune responses and promoting regeneration. The sacrificial anodic process of Zn‐0.8Mg reduced Zn2+ release compared to the “large cathode‐small anode” coupling of Zn‐0.8Fe.

American Journal of Botany, EarlyView.Abstract Premise Symbioses between lichen‐forming fungi and brown algae (phaeophytes) are extremely rare. We investigated the interactions between the marine fungus Collemopsidium pelvetiae and its two photosynthetic partners, the brown alga Pelvetia canaliculata and a cyanobacterial symbiont to address questions on symbiosis biology, lichenization ...

Effect of Wear on Alternating Bending Fatigue Life of 20CrNi2Mo Martensitic Steel
LubricantsBending fatigue failures are commonly related to the wear behavior in an active system. The surface wear and plastic deformation of the tribolayer play crucial roles in the wear–bending fatigue behaviors of steels.
