Curcumin regulates EZH2/Wnt/β-Catenin pathway in the mandible and femur of ovariectomized osteoporosis rats.

Osteoporosis (OP) behaves in different manners in different parts of the skeleton. This study aims to investigate the effects of curcumin on bone mass of the mandibular and femur from ovariectomized OP rats and to validate whether enhancer of zeste homolog 2 (EZH2)/Wnt/β-Catenin pathway is involved in this process. Curcumin was administered intragastrically into ovariectomized rats for 12 weeks.

Influence of low modulus Co-Zr alloys surface modification on protein adsorption and MC3T3-E1, NIH3T3 and RAW264.7 cell behaviour.

Three types of Co-xZr (x = 5, 7.5, and 10 wt.%) were treated with hydroxyapatite (HA) and used as an object to investigate the effect of HA coating on the surface and biocompatibility of Co-xZr alloys.
