Clinical characteristics of patients with leiomyoma who undergo surgery after high intensity focused ultrasound (HIFU).

Objective: We evaluated the clinical characteristics of patients who underwent surgery after high intensity focused ultrasound (HIFU) to treat uterine leiomyoma.

Methods: From June 2016 to September 2017, patients at our hospital who underwent HIFU to treat uterine leiomyoma prior to surgery were enrolled. All patients underwent pelvic magnetic resonance imaging (MRI) before and after HIFU.

Surface grafting of octylamine onto poly(ethylene-alt-maleic anhydride) gate insulators for low-voltage DNTT thin-film transistors.

This study investigates a spin-coating method for modifying the surface properties of a poly(ethylene-alt-maleic anhydride) (PEMA) gate insulator. The 60 nm-thick PEMA thin film exhibits excellent electrical insulating properties, and its surface properties could be easily modified by surface grafting of octylamine. Due to surface treatment via spin-coating, the surface energy of the PEMA gate insulator decreased, the crystal quality of the organic semiconductor improved, and consequently the performance of low-voltage organic thin-film transistors (TFTs) was enhanced.
