Abstract: Provided are novel determination techniques and systems enabling an AI process in which decisions are made from the viewpoint of allowing an expert to make a decision, and capable of providing a valid answer, even with a small amount of learning data, by adjusting errors in both the answer of the expert and the answer of AI. A system is configured to cause an AI process to be performed on subject teacher data for AI learning in which events of objects identified by identifying codes are divided into classes, and data pertaining to an object for which class determination of an event is required, and to receive class determination data obtained by the AI process.

Abstract: A cardiac myocyte protective agent, comprising a compound represented by the formula (Ia) below, a pharmaceutically acceptable salt thereof, or a solvate thereof:

Abstract: A peptide identified from the annexin V protein sequence and having the ability to modulate the activity of delta protein kinase C (PKC) is described. The peptide and variants thereof bind to delta PKC and are effective to regulate delta PKC mediated cellular responses. In particular the annexin V peptide is able to inhibit protein-protein interaction with delta PKC, blocking intracellular translocation of delta PKC. Inhibition of delta PKC translocation confers protection to tissue at risk of exposure to ischemia or hypoxia or to reperfusion injury.

Abstract: A therapeutic and/or prophylactic drug for cardiac failure and cardiac hypertrophy, comprising a derivative of hydroxamic acid, which is represented by the formula (I) 1
