K nearest neighbor classification is one of the most successfully used methods in pattern recognition. Despite its simplicity and effectiveness, it suffers from several shortcomings referring to high computational cost, high storage requirement and sensitivity to noise. Prototype generation is an appropriate data reduction process to alleviate these(More)
Platelet‑rich plasma (PRP) is a promising strategy for intervertebral disc degeneration (IDD). However, the short half‑life of growth factors released from PRP cannot continuously stimulate the degenerated discs. Thus, the present study hypothesized that the combined use of PRP and bone marrow‑derived mesenchymal stem cells (BMSCs) may repair the early(More)
