  • Publication number: 20090281142
    Abstract: [Problem] To provide a compound which is useful as a GK activator. [Means for Resolution] As a result of an extensive study on thiazole derivatives, the present inventors have found that a compound having an oxamoyl group, a glycol group or the like on a thiazole ring and a compound having an acetamide group substituted by a bicyclic heteroaryl group such as a quinolyl have a good GK activation effect, and thereby have accomplished the present invention. Since the compounds of the present invention have a good GK activation effect, these are useful as therapeutic agents for diabetes, particularly type II diabetes.

  • Patent number: 7249883
    Abstract: A deep-area temperature calculating device 441 calculates the temperature Tcore of a deep area on the basis of a first body-surface temperature and second body-surface temperature from body-surface sensors 31A and 31B, and on the basis of a first intermediate temperature and second intermediate temperature from intermediate sensors 32A and 32B. Since the temperature Tcore of the deep area is determined from two body-surface temperatures and two intermediate temperatures, the temperature Tcore of the deep area can be calculated regardless of the heat resistance of the thermometer without making any assumptions regarding the heat resistance of the area that extends from the deep area of the human body to the body surface. Thereby, the temperature Tcore of the deep area can be calculated and the body temperature can be measured with high precision regardless of differences in the body type or contact with clothing or bedding.
