Abstract: A fixing device includes a fixing rotator, a pressure rotator, a heat source, a nip formation pad, and a support. The nip formation pad presses against the pressure rotator to form a fixing nip between the fixing rotator and the pressure rotator. The support supports the nip formation pad toward the fixing nip. A longitudinal end portion of the pressure rotator has an outer diameter greater than that of a longitudinal center portion of the pressure rotator. The pressure rotator includes a grip that contacts the nip formation pad via the fixing rotator outside a recording medium with a maximum width conveyable passing through the fixing nip and applies a frictional force to the fixing rotator. The nip formation pad includes a nip face having an inflection point from which a longitudinal direction of the nip face is curved toward the support within an area opposite the grip.

Abstract: An object of the present invention is to develop a biomarker for discriminating dementia, particularly, Alzheimer's disease and mild cognitive impairment which can progress to Alzheimer's disease, from other central nervous system diseases, or capable of determining a pathological condition of dementia, and provide a method for diagnosing dementia early and a method for determining a pathological condition of dementia, using the biomarker. A transferrin glycoprotein containing a glycan having at least one mannose at a non-reducing end or a transferrin fragment containing the glycan is used as a diagnostic marker for Alzheimer's disease.

Abstract: A paper sheet authentication apparatus determines the type of the paper sheet by using a characteristic other than a fluorescent light characteristic, sequentially emits excitation lights of different wavelengths on the paper sheet, measures an intensity of light per wavelength within a predetermined range emitted by a fluorescent material applied to the paper sheet, and acquires fluorescent light characteristic data as the result. The paper sheet authentication apparatus performs the authentication of the paper sheet by using fluorescent light characteristic data of a genuine paper sheet previously stored per type of the paper sheet or a threshold calculated therefrom and the acquired fluorescent light characteristic data.
