Abstract: A flush toilet includes a bowl part, a drainage water trap part that is connected to a bottom part thereof, and a water drainage socket that is connected thereto and includes a back side R part that changes a flow channel so that washing water flowing from an upper side is directed to a front side, a front side R part that is provided on a downstream side of the back side R part and changes a flow channel so that washing water flowing from a back side is directed to a lower side, a water storage part that stores a part of washing water on a flow channel from the back side R part to the front side R part, and a throttle part that is provided on a downstream side of the front side R part and decreases a cross-sectional area of a flow channel thereof.

Abstract: Cyclic compounds and oligopeptide compounds that selectively inhibit KRAS were found. Oligopeptide compounds and non-natural amino acids useful for producing a cyclic compound were also found. Moreover, cyclic compounds and oligopeptide compounds were found to interact with an amino acid residue specific to KRAS.

Abstract: A differential amplifier includes: a constant current source; first and second field effect transistors whose respective gates are imparted with positive-phase and negative-phase input signals and whose sources commonly connected to each other, the constant current source being connected to a common node of the sources; first and second loads serving as current paths for respective drain currents of the first and second field effect transistors; an amplifying unit which outputs positive-phase and negative-phase output signals which are amplified in response to the respective drain voltages of the first and second field effect transistors; and a current path generator which generates first and second current paths parallel to the respective first and second field effect transistors for a predetermined period of time at the time of start-up of the differential amplifier.
