.Joint injection of biodegradable PMMA with hyaluronic acid for bone tissue engineering.
The biodegradation of PMMA can be controlled by adding Ca(2+) ions and the degradation products of Ca(2+) can induce cell adhesion and differentiation. Additionally, biodegradable hyaluronic acid (HA) can enhance the hydrophilicity of a scaffold surface and enhance the adhesion and proliferation of cells. Therefore, in this study, two types of PMMA-based scaffolds with and without HA were prepared and cell adhesion and cell viability were investigated to investigate their potential as scaffolds for bone tissue engineering. The effects of PMMA degradation and HA on cell adhesion and proliferation were evaluated. Cell proliferation and live/dead staining were analyzed in both scaffolds. Interestingly, cell adhesion and proliferation in the PMMA-based scaffold with HA were better than those in the PMMA-based scaffold without HA. Our results indicate that HA could be used to control the biodegradation of biodegradable PMMA scaffolds and that the introduction of HA can enhance the bioactivity of the PMMA-based scaffold for bone tissue engineering.Juan Manuel García (athlete)

After a summer full of false optimism, thanks in large part to the fact that the official start of the league was pushed back by a day, everything has turned out to be anticlimactic, and our draft is a complete embarrassment. The draft lottery is expected to be moved from May 17 to May 18, but even that has been pushed back and will now take place on May 17 at 7 p.m. ET on ESPN. We’re living in the wrong century.
But with three and a half months until the draft (which begins June 26), where does that leave 0b46394aab
