"It's an exceptional find.
Fortunately, Bolet said, Méndez "immediately realized that what he had found was a small vertebrate skull, a rather exceptional finding, because screen-washing techniques mostly retrieve disarticulated bones and isolated teeth".
Pneumorrhachis (PR) is an exceptional radiological finding consistent with air in the spinal canal.
One exceptional finding was that in the absence of dithionite as the reductant, TsrM continued to generate SAH, thereby indicating that radical SAM chemistry was not a required precursor to methyl group transfer.
This exceptional finding of favourable prognosis for DNA aneuploid tumours was more prominent among patients receiving intensive systemic therapy and among patients with stage IV disease, probably indicating a tendency for DNA aneuploid tumours to have higher sensitivity to systemic therapy.
While there were some other statistically significant results, as would be expected by chance alone when multiple comparisons are made, there were no other cancer sites with consistently exceptional findings.
Professor and author of the study paper Fernando Pardo-Manuel de Villena said: "This is an exceptional new research finding that opens the door to an entirely new area of exploration in human genetics".
