  • Patent number: 11660286
    Abstract: The invention provides methods, compositions, and medical kits comprising a nitrite-reductase promoter, such as an allosteric modulator of hemoglobin, for use in treating medical disorders and preservation of blood products. In one aspect, the invention provides methods, compositions, and medical kits comprising an inorganic nitrite salt and a nitrite-reductase promoter, such as an allosteric modulator of hemoglobin, for use in treating medical disorders, such as cancer, cardiovascular disorders, ischemic conditions, hemolytic conditions, and bacterial infections. Exemplary inorganic nitrite salts include sodium nitrite and arginine nitrite. Exemplary allosteric modulators of hemoglobin described herein include alkyl-substituted and acyl-substituted di-nitroheterocycles.
    Type: Grant

  • Patent number: 6368874
    Abstract: Disclosed are chemical encryption methods for determining the structure of compounds formed in situ on solid supports by the use of specific amines tags which, after compound synthesis, can be deencrypted to provide the structure of the compound found on the support.

  • Patent number: 6148275
    Abstract: An improved system or and method of connecting a hardware modeling element to the pin electronics circuitry of a hardware modeling system, with the improved system having circuitry and structures that will allow it to be connected to a hardware modeling system that is powered, circuitry to indicate to the pin electronics circuitry that the improved system is connected to it, circuitry to identify the hardware modeling element supported by the improved system to the hardware modeling system, circuitry to indicate to the hardware modeling system when the hardware modeling element is initialized so evaluation of it by the hardware modeling system can commence, circuitry to generate selectable supply voltages for the powering the hardware modeling element, and a hardware modeling element connector that will allow the connection of a family of hardware modeling elements to the same connector without the need to change the connector.
