Expression and functional characterization of His-tagged prestin in Chinese hamster ovary cells.

The electromotility of outer hair cell is considered to be based on voltage-dependent conformational changes in the motor protein prestin. The structure and function of prestin have been increasingly examined in recent years. To obtain further information on prestin, a method to stably obtain prestin as the material for this research is required.

Wideband frequency impedance for diagnosis of ossicular chain abnormality.

Background: The accurate estimation of the ossicular chain abnormalities using existing functional examinations has been difficult.

Aims/objectives: This study aimed to verify the accuracy of preoperative diagnosis of ossicular chain abnormalities using a wideband frequency impedance (WFI) meter, which can measure the dynamic characteristics of the middle ear.

Material And Methods: Retrospective cohort study.
