Is the image of the hard palate/nasal fossa floor in panoramic radiography : the controversy over?
The junction of the nasal septum with the NFF and the posterior portions of the HP/NFF form the upper image of the HP/NFF. Most of the image is real, although a small part is a ghost image of the horizontal plates of the palatine bones and of the posterior region of the palatine processes of the maxillae.
These results suggest that Drosophila BLM suppresses error-prone alternative end-joining repair of DNA double-strand breaks that can result in genome instability and tumor formation during aging. In addition, since loss of BLM significantly affects lifespan and tumorigenesis, the data provide a link between error-prone end joining, genome rearrangements, and tumor formation in a model metazoan.
