Abstract: A bone graft generation and delivery process can include inserting bone material into an impactor system. The process can include processing, via the impactor system, the bone material into bone graft material. Processing the bone material can include milling the bone material via a first rotational element of the impactor system. Processing the bone material can include cutting the bone material via a second rotational element of the impactor system. Processing the material can include filtering the cut and milled bone material to isolate bone graft material. The process can include delivering, via the impactor system, the bone graft material to a target site.

Abstract: The present invention is an isolated and purified DNA sequence which encodes a vertebrate mRNA for a neuron specific protein, neuronatin. The mRNA is selectively expressed in brain tissue during rapid brain growth when there is a surge in neuronal proliferation and migration and is repressed in adult tissue. In the human, the genomic DNA is as set forth in SEQ ID No:6 and the cDNA has a nucleotide sequence as set forth in SEQ ID No:5, with the gene mapped to human chromosome 20q11.2-12. The deduced protein is a proteolipid that appears to have a role in ion channel regulation during brain development.
