OBJECTIVES We tried to clarify the correlation of the expression of CCR7 and CXCR4 with lymph node and distant metastasis. MATERIALS AND METHODS We examined expression of CCR7 and CXCR4 in 9 HNSCC cell lines and 25 HNSCC tissues by semi-quantitative RT-PCR and immunohistochemistry study. We examined the expression levels of CCR7 and CXCR4 in(More)
In this article, we investigate the plus space of levelN , where 4−1N is a square-free (not necessarily odd) integer. This is a generalization of Kohnen’s work. We define a Hecke isomorphism ℘k of Mk+1/2(4M) onto M k+1/2(8M) for any odd positive integer M . The methods of the proof of the newform theory are this isomorphism, Waldspurger’s theorem, and the(More)
Positron Emission Tomography (PET) is an effective imaging technique to detect cancers, but interpretation of PET images is difficult for radiologists who have insufficient knowledge and experience. Radiologists could interpret PET images more effectively if they were able to share their PET expertise. To realize this goal, our recent efforts have designed(More)
