"Characterization of polycaprolactone nanohydroxyapatite composites wit" by Stephanie E. Doyle, Lauren Henry et al.


Abstract
Degradable bone implants are designed to foster the complete regeneration of natural tissue after large-scale loss trauma. Polycaprolactone (PCL) and hydroxyapatite (HA) composites are promising scaffold materials with superior mechanical and osteoinductive properties compared to the single materials. However, producing three-dimensional (3D) structures with high HA content as well as tuneable degradability remains a challenge. To address this issue and create homogeneously distributed PCL-nanoHA (nHA) scaffolds with tuneable degradation rates through both PCL molecular weight and nHA concentration, we conducted a detailed characterisation and comparison of a range of PCL-nHA composites across three molecular weight PCLs (14, 45, and 80 kDa) and with nHA content up to 30% w/w. In general, the addition of nHA results in an increase of viscosity for the PCL-nHA composites but has little effect on their compressive modulus. Importantly, we observe that the addition of nH ....

Modern bone healing: Scientists design device that helps accelerate bone regeneration


https://www.afinalwarning.com/467620.html
(Natural News)
As many as 6.3 million cases of bone fracture are reported in the U.S. annually. While the body usually begins to repair itself within minutes of a fracture’s occurrence, that process can sometimes be impaired. This can result in debilitating injuries.
As a way to address the latter, surgeons at the
University of Michigan Medicine (U-M) are now developing a device that can help accelerate bone regeneration.
As described in the journal
Regenerative Medicine, this development is anchored on the stimulation of the angiogenesis process, the phase of blood vessel development critical to bone healing. ....
