Recent advances in physics have made possible the use of non-thermal atmospheric pressure plasma (NTP) in cancer research. Although increasing evidence suggests that NTP induces death of various cancer cell types, thus offering a promising alternative treatment, the mechanism of its therapeutic effect is little understood. In this study, we report for the(More)
BACKGROUND Hepatocyte growth factor (HGF) can promote proliferation, invasion, and angiogenesis in various tumor cells. However, the prognosis according to expression of HGF/c-Met has not been reported in patients with squamous cell carcinoma of the oral tongue (SCCOT). METHODS Tumors from 61 patients with SCCOT were evaluated for the expression of HGF(More)
Pure macroscopic single-walled-carbon-nanotube (SWNT) fibers are fabricated by using a dip-coating method without any additive or additional electrical equipment or complex apparatus. The present method only utilizes microfluidics, which includes capillary condensation, capillary flow, and surface tension, and results in the self-assembly and self-alignment(More)
Mucosal melanoma is a very rare disease. Most cases have their origins in the head and neck region. To date,only three cases of melanoma originating from the eustachian tube have been reported. We present a case of mucosal melanoma of eustachian tube origin in which a complete excision was performed. In this case, the patient underwent adjuvant radiotherapy(More)
Novel carbon-based microporous nanoplates containing numerous heteroatoms (H-CMNs) are fabricated from regenerated silk fibroin by the carbonization and activation of KOH. The H-CMNs exhibit superior electrochemical performance, displaying a specific capacitance of 264 F/g in aqueous electrolytes, a specific energy of 133 Wh/kg, a specific power of 217(More)
OBJECTIVE The aim of this study was to present the various strategies adopted in our center to improve and overcome problems with exposure of the operative field in 48 patients who underwent TORS for the treatment of laryngeal and hypopharyngeal cancer. METHODS We present our operative and preoperative treatment protocols for patients undergoing TORS for(More)
An ectopic hamartomatous thymoma is an extremely rare benign tumor of the lower neck that is the most common in middle-aged males. Pathologically, the tumor is characterized by a mixture of spindle cells, epithelial cells, mature adipose tissue, and lymphocytes. The histogenesis of this tumor is controversial. Recently, an origin from a remnant of the(More)
Reduced graphene oxide nanoribbon fibers were fabricated by using an electrophoretic self-assembly method without the use of any polymer or surfactant. We report electrical and field emission properties of the fibers as a function of reduction degree. In particular, the thermally annealed fiber showed superior field emission performance with a low potential(More)
