    摘要： The present invention provides tissue sealant compositions and vasculature closure devices useful for the optical detection of tissue seal and/or clot formation. Compositions and devices of the present invention comprise optical dyes which undergo an observable change as the compositions and/or devices are incorporated into a tissue seal and/or clot, for example a change in fluorescence quantum yield and/or a change in visual color including a change in emission and/or absorption wavelength. Tissue sealants and vasculature closure devices of the present invention are useful for visualizing seal and/or clot formation, for example, during or after surgical procedures, after catheter removal, etc. The present invention further provides methods for formation and optical detection of tissue seals or vasculature puncture closures as well as medical kits useful for the formation and optical detection of tissue seals or vasculature puncture closures.

    摘要： The present invention relates to pyrazine derivatives such as those represented by Formulas I and II. X1 to X4 of Formulas I and II may be characterized as electron withdrawing groups, while Y1 to Y4 of Formulas I and II may be characterized as electron donating groups. Pyrazine derivatives of the present invention may be utilized in assessing organ (e.g., kidney) function. In a particular example, an effective amount of a pyrazine derivative that is capable of being renally cleared may be administered into a patient's body. The pyrazine derivative may capable of one or both absorbing and emanating spectral energy of at least about 400 nm (e.g., visible and/or infrared light). At least some of the derivative that is in the body may be exposed to spectral energy and, in turn, spectral energy may emanate from the derivative. This emanating spectral energy may be detected and utilized to determine renal function of the patient.

    摘要： The present invention relates to pyrazine derivatives such as those represented by Formulas I and II below. X1 to X4 of the compounds of Formulas I and II may be characterized as electron withdrawing groups. In contrast, Y1 to Y4 of the compounds of Formulas I and II may be characterized as electron donating groups. Pyrazine derivatives of the present invention may be utilized in assessing renal function. In particular, an effective amount of a pyrazine derivative of the invention may be administered into a body of a patient. The pyrazine derivative that is in the body may be exposed to visible and/or infrared light to cause spectral energy to emanate from the pyrazine derivative. This emanating spectral energy may be detected and utilized to determine renal function of the patient.
