BACKGROUND: Water homeostasis is essential for inner ear function. Several aquaporins (AQPs), which are water transport proteins in the cell or plasma membrane, have been reported in the lateral wall of the rat inner ear (cochlea). However, the presence of AQP-10, -11 and -12 has not been reported in the rat stria vascularis (SV) to date. AIMS/OBJECTIVES: We have aimed to clarify the expression of AQP-10, -11 and -12 in the cochlea lateral wall. MATERIALS AND METHODS: Using Wistar rats, we examined the expression of AQP-10, -11 and -12 in the cochlea lateral wall using molecular approaches and immunohistochemistry...

BACKGROUND: Early glottic cancer can be treated with laser resection or radiotherapy. In an earlier study, we found that voice function after laser resection was inferior to that after radiotherapy. OBJECTIVES: This study was designed to determine if reduced margins at laser resection improved voice function without impairing oncologic results. METHOD: A total of 268 patients with previously untreated T1-T2 glottic carcinoma were studied. They were primarily treated with either radiotherapy ( n  = 119) or laser resection ( n  = 149)...
