The purpose of this work was to examine outcomes in patients with T4 nasopharyngeal carcinoma (NPC) treated with intensity-modulated radiation therapy (IMRT). Between 2007 and 2010, 154 patients with nonmetastatic T4 NPC were treated with IMRT to a total dose of 70 Gy in 33–35 fractions. In addition, 97 % of patients received concurrent platinum-based(More)
A novel real-time quantitative method for detecting HCV in serum was established in which the duplex scorpion primer was used to provide a unimolecular probing mechanism for hybridizing the highly conserved 5′ noncoding region (5′ NCR) of the HCV genome specifically. Through methodological evaluation, we found this new method had a wide linearity, high(More)
The activities of two crucial enzymes of reverse cholesterol transport, cholesterol ester transfer protein (CETP) and lecithin:cholesterol acyltransferase (LCAT), and their relationships with lipid profile and fasting plasma glucose were examined in 35 type 1 diabetic children. The CETP and LCAT activities were significantly lower (p<0.05) in the 4 subjects(More)
This paper presents a new isolated dc/dc converter with zero-voltage turn-on switching (ZVS) of power switches and zero-current turn-off switching (ZCS) of diodes. In conventional flyback converter, the main drawbacks are high voltage stresses on power devices large transformer size, and serious reverse recovery current which resulted in high voltage spike(More)
This paper presents a zero voltage switching (ZVS) Cuk converter with double ended rectifier to reduce switching losses on power semiconductors, decrease voltage stresses on rectifier diodes and achieve power delivery to output load in positive and negative half cycle of the secondary winding voltage. An auxiliary switch and a clamp capacitor are connected(More)
Conventional x-ray diffraction patterns were recorded and used for peak identification and phase determination of MBE multilayer Pt/FePt/Pt thin films on MgO single-crystal substrates. Results showed that both the FePt and the Pt layers were either epitaxially grown or strongly textured with the (110) planes parallel to the surfaces of the MgO (110)(More)
