Growing evidence suggests that interleukin-8 (IL-8) play pivotal roles in the pathogenesis of cancer through the modulation of tumour immune response or enhanced angiogenesis. A single nucleotide polymorphism, –251A/T, has been identified in the promoter region of the IL-8 gene and has been shown to influence its production. Results from previous studies on the association of –251A/T polymorphism...
Brachytherapy is one of the major means of nasopharyngeal carcinoma treatments. The process of radioactive source delivery and the distribution of radioactive dose are two pivotal factors of brachytherapy planning. A new method for simulation of the two factors was proposed in this paper. Firstly, the CT images of the nasopharyngeal tissues were segmented and the 3D models of nasopharyngeal tissues...
Nasopharyngeal tissue modeling is the base of computer simulation of nasopharyngeal carcinoma therapy. Nasopharyngeal tissue was segmented by a combine of doctor's sketch and mathematical morphology method. A color lookup table was made for the fast recognition of about sixty tissues. For there are many tissues around nasopharynx, level-of-detail tactic is used to reconstruct different tissues by...
