  • Publication number: 20100114002
    Abstract: A method for controlling the blood glucose level of a patient and periodically calibrating the glucose sensor using a calibration solution. The method controls the level of blood glucose in a patient through an extracorporeal blood circuit by: withdrawing blood from a vascular system in the patient to the extracorporeal circuit; removing ultrafiltrate from the withdrawn blood in the circuit; determining a level of glucose present in the blood based on the removed ultrafiltrate; infusing at least a portion of the removed ultrafiltrate and the withdrawn blood into the vascular system, and infusing insulin into the patient based on the determined level of glucose.

  • Publication number: 20090270508
    Abstract: The present invention provides for compositions and methods for modulating the GluR2 receptor. It is based, at least in part, on the discovery, by X-ray crystallography, that a known GluR2 agonist binds to the receptor in two different orientations, thereby diminishing its potency. The present invention provides for structural alternatives in which alternative binding possibilities are substantially eliminated.

  • Publication number: 20080286877
    Abstract: Complex of an anti-cocaine aptamer and the dye diethylthiotricarbocyanine behaves as a calorimetric sensor with attenuation in absorbance at 760 nm for cocaine in the concentration range of 2-5000 ?M. Mechanistic studies indicate an intermolecular displacement of the dye as the mechanism of action of the sensor. As the dye is insoluble in buffer, cocaine binding can be detected as displaced dye precipitates and supernatant decolorizes.
