Abstract: A first calculation unit receives phase characteristics Pa(f) and Pb(f) outputted from frequency transform units, calculates a propagation time difference based on a phase difference between the two phase characteristics in a high-frequency component thereof, and calculates a pulse wave velocity by dividing a difference in the distances of vascular pathways from the heart to respective measurement areas. Meanwhile, a second calculation unit calculates a pulse wave velocity by dividing the stated difference in the distances by a appearance time difference at a predetermined position in respective pulse waveforms obtained by rendering the measurement signals Pa(t) and Pb(t) on a time axis. A comparison unit compares the pulse wave velocities, and in the case where the ratio thereof is outside a predetermined range, an evaluation result indicating that it is possible that a predetermined pathologic change is present in the vascular pathway is outputted to a display processing unit.

Abstract: The present invention provides a novel cancer marker that is useful in the diagnosis of urothelial cancer. The present invention uses ubiquilin 2 as a cancer marker for urothelial cancer (renal pelvis cancer, ureteral cancer, and bladder cancer). Detection of ubiquilin 2 in a urine sample allows easy and accurate diagnosis of a possibility of urothelial cancer. The present invention is also applicable to the diagnosis of squamous cancer (esophageal cancer, cervical cancer, etc.).

Abstract: Various methods for evaluating hemostatic effect and various blood coagulation initiation reagents were studied to construct a method for evaluating blood coagulation reaction mediated by a substance having an activity of substituting for coagulation factor VIII (FVIII). As a result, it was discovered that by using a coagulation initiation reagent containing activated coagulation factor XI (FXIa) and phospholipids, the effect of a substance having an activity of substituting for coagulation factor VIII (FVIII) on blood coagulation reaction can be evaluated using the amount of thrombin generated in the blood sample as an indicator.
