  • Patent number: 11954850
    Abstract: A medical information processing system according to an embodiment includes processing circuitry and a display. On the basis of one of the type of at least one abnormality detection algorithm to which a medical image related to an examined subject is to be input and information relevant to an abnormality detected by inputting the medical image to the abnormality detection algorithm, the processing circuitry judges whether or not urgency is present in a disorder related to the abnormality. When it is determined that the urgency is present, the display displays, in an examination list of examination orders, assessment information related to assessing the abnormality and urgency information indicating the urgency so as to be positioned adjacent to any of the examination orders related to the abnormality.

  • Patent number: 4968523
    Abstract: A shellfish extract concentrate is prepared by subjecting an extract of a shellfish (exclusive of oyster) having a solid concentration not higher than 30% by weight to an adsorption purification treatment with an adsorbent composed mainly of a water-insoluble inorganic magnesium compound, which has a specific surface area of at least 50 m.sup.2 /g, and concentrating the refined liquid in a substantially non-oxidizing atmosphere. In this shellfish extract concentrate, black and blackish brown coloring components are not contained, and flavor components and nutrients are not substantially lost. Accordingly, this shellfish extract concentrate is excellent in taste, flavor and hue.
