Abstract: A stent is formed of a shape-memory alloy and is to be inserted and placed inside a three-dimensional model of a biological organ manufactured for training, under a state in which the stent is mounted on a balloon of a balloon catheter. The stent is expandable under a room temperature environment. When heated to a predetermined temperature higher than room temperature, the stent is contracted until an inner diameter of the stent becomes smaller than an outer diameter of the balloon in a contracted state, and returns to an original shape thereof.

Abstract: An apparatus (1) includes an exercise sensor (31) that continuously detects a movement of an exerciser accompanied by intermittent exercise, and a heart rate meter (32) that continuously measures a heart rate of the exerciser, and further includes an activity detection unit (12), a heart rate monitoring unit (13), an activity monitoring unit (14), and a notification processing unit (15). The activity detection unit (12) detects, from the movement of the exerciser, an activity intensity, a high activity intensity period, and a low activity intensity period. The heart rate monitoring unit (13) detects a declining trend in the heart rate of the exerciser, in the low activity intensity period each time, and monitors whether or not the declining trend of this time is low as compared with a predetermined reference. The activity monitoring unit (14), in a case in which the monitoring by the heart rate monitoring unit is affirmed, monitors whether or not the activity intensity to be detected in the high activity intensity period of a next time is low as compared with activity intensities detected in high activity intensity periods up to a previous time. The notification processing unit (15), in a case in which the monitoring by the activity monitoring unit is affirmed, forecasts an outbreak of disease. With this configuration, the outbreak of disease in an exerciser during an exercise is forecasted with higher accuracy.

Abstract: An evaluation method is performed by an arithmetic circuit and includes obtainment processing (S1), evaluation processing (S2), and presentation processing (S3). The obtainment processing (S1) obtains: image information on a sectional image representing an interested section of an organism including a target section of a testis of the organism generated by use of magnetic resonance of hydrogen atoms; and concentration information on a creatine concentration in the interested section measured by use of magnetic resonance based on chemical exchange saturation transfer. The evaluation processing (S2) generates an evaluation image representing a distribution of evaluation results of a testicular function in the target section based on the concentration information. The presentation processing (S3) presents the sectional image and the evaluation image.
