Abstract: A high-temperature wide-bandgap power module and a preparation method thereof is provided in the present application. In the high-temperature wide-bandgap power module, SiC power chips are arranged in the cavity, and bonding wires are used to establish electrical connections.

Abstract: A biomarker composition for predicting susceptibility to a therapeutic agent for neurofibromatosis by using Ras activity; and a pharmaceutical composition for preventing or treating neurofibromatosis, including a Ras activity inhibitor. The biomarker composition can accurately diagnose susceptibility to a therapeutic agent for neurofibromatosis by measuring the expression levels of a GTP-bound and activated Ras (Ras-GTP) protein and an activated p-ERK protein or a gene encoding the same in a biological sample of an individual. The pharmaceutical composition inhibits the activity of Ras proteins, and thus can be effectively used for the prevention or treatment of neurofibromatosis in which the activity of the Ras proteins is increased.
