RESUMO
A low-cost, solution-processed, versatile, microfluidic approach is developed for patterning structures of highly conductive metals (e.g., copper, silver, and nickel) on chemically modified flexible polyethylene terephthalate thin films by in situ polymer-assisted electroless metal deposition. This method has significantly lowered the consumption of catalyst as well as the metal plating solution.
RESUMO
OBJECTIVE: To investigate the surgery management of glottic carcinoma with high-frequency electrotome. METHOD: Twenty cases of patients with glottic carcinoma were treated by cordectomy under micro-laryngoscopy with high-frequency electrotome. RESULT: The 20 patients were followed up from 5 months to 6 years, retained good laryngeal function and structure: 1 case had local recurrences after 6 months, underwent total laryngectomy, and now no recurrence had been found: 19 cases (mild adhesions of vocal cords formed in 2 cases) had no local recurrence nor lymph node metastasis. CONCLUSION: It is unnecessary to invest in expensive equipment in the cordectomy under micro-laryngoscopy with high frequency electrotome under general anesthesia and the result is satisfactory.
