  • Publication number: 20110166151
    Abstract: The object aims to find a novel pharmacological activity of a novel 1,2,3,4-tetrahydroquinoxaline derivative which contains, as a substituent, a phenyl group having a sulfonic acid ester structure introduced therein. A compound represented by general formula (1) or a salt thereof is useful as a glucocorticoid receptor agonist, particularly as a therapeutic agent for diseases against which a glucocorticoid receptor agonist (e.g., a steroid) is believed to be effective, such as inflammatory bone/joint diseases, inflammatory ophthalmic diseases (inflammatory ophthalmic diseases in the anterior or posterior segment of an eye).

  • Publication number: 20110115441
    Abstract: A charging control method for a non-aqueous electrolyte secondary cell is a charging control method for controlling a state of charge of a non-aqueous electrolyte secondary cell that has a non-aqueous electrolyte between electrodes, a target state of charge serving as a target for stopping charging is preset in correspondence with an ambient temperature of the non-aqueous electrolyte secondary cell, and the target state of charge (e.g., 95%) for when the ambient temperature is a specific temperature (e.g., 25° C. or 20° C. to 30° C.) that has been specified in advance is set higher compared to the target state of charge for a temperature other than the specific temperature.
