Abstract: An information processing apparatus determines, for each of a first radiation image corresponding to a first radiation energy and a second radiation image corresponding to a second radiation energy different from the first radiation energy, a first bone area indicating a predetermined bone portion, performs an alignment between a first partial area including the first bone area in the first radiation image and a second partial area including the first bone area in the second radiation image, and obtains a bone mineral density of the first bone area based on a difference image including the first bone area, the difference image is obtained based on a result of the alignment.

Abstract: A therapeutic agent for amyotrophic lateral sclerosis including a compound represented by Formula (1) [in Formula (1), R1 each independently represents an alkyl group having 1 to 6 carbon atoms or 4-hydroxyphenethyl group, and n represents an integer of 1 to 3], a pharmaceutically acceptable salt thereof, or a solvate thereof, as an effective ingredient.

Abstract: A culture medium for inducing a pluripotent stem cell into a differentiation-promoted pluripotent stem cell, the medium including a Glycogen synthase kinase 3? (GSK3?) inhibitor, a Bone morphogenic protein (BMP) signaling inhibitor, and a Transforming growth factor (TGF)-? inhibitor as active ingredients.

Abstract: A method is provided for uniformly differentiating a pluripotent stem cell into a neural stem cell, with elimination of variation among cell strains or clones of the pluripotent stem cell and without formation of an embryoid body, regardless of the origin of the pluripotent stem cell
