Nasopharyngeal carcinoma (NPC) is a relatively rare malignancy in Western countries, but it is the most commonly diagnosed head and neck cancer in Southeast Asia. Early-stage NPC usually has no specific symptoms. Common signs and symptoms in advanced disease include cervical lymphadenopathy, nasal blockage, a nasal twang, and symptoms associated with distant metastasis such as bone...
Radiation therapy is the mainstay therapeutic modality for nasopharyngeal carcinoma (NPC). In the last two decades, advances in the diagnostic and treatment techniques in cancer management have significantly improved prognosis of NPC, including the long-term local and regional disease control as well as patients' overall survival. With definitive radiation therapy for early stage disease and combined...
Nasopharyngeal carcinoma (NPC) is highly sensitive to ionizing radiation, and radiation therapy is the mainstay treatment modality for nonmetastatic disease. For decades, NPC radiation therapy utilizes conventional treatment using two-dimentional and lately three-dimentional techniques. Both techniques mainly utilize opposed lateral fields with or without a supplement anterior field focused to the...
An apparatus for detecting advanced glycation Endproducts (AGE) fluorescence spectrum of skin has been designed. Some of the AGE have special fluorescence. When the tissue of skin is illuminated with excitation light, fluorescence emmited by tissue is detected. The intensity of detected fluorescence is related with the concentration of tissue AGE, which can determine a tissue state of individual....
Based on the fact that Web service dynamically changes and rapidly increases in the Internet, a task-oriented service cooperative scheduling model is proposed. In the model, Web service composition is scheduled in terms of interacting components, namely, task and services under the constraint of resources. The scheduling model focuses on the competence of Web service composition under the constraint...
