Abstract: The present invention provides a fluorogenic composition for assaying complement activation that comprises a substrate for C3 convertase that is linked to a first fluorophore and a second fluorophore, wherein the fluorescence of the first and second fluorophores are mutually substantially quenched when the two fluorophores are present at a distance less than the characteristic distance for the two fluorophores. In one embodiment, the fluorescence of the first fluorophore is substantially quenched by the second fluorophore, and the second fluorophore emits heat upon quenching. The present invention also provides a method for assaying complement activation, wherein the method includes the steps of incubating a biological sample with a polymer to provide a polymeric biological sample, followed by incubating the polymeric biological sample with the fluorogenic composition, and measuring the fluorescence.

Abstract: Provided herein are techniques for screening materials for hemocompatibility. Hemocompatible materials may be advantageous when incorporated into devices that may come into direct contact with blood or other bodily fluids. Such techniques take advantage of conformational changes in fibrinogen when adsorbed onto certain materials. As a result of conformational changes, the fibrinogen has altered responsiveness to cleavage by thrombin. Accordingly, the products of thrombin cleavage of fibrinogen may be assessed to determine the hemocompatibility of a material.

Abstract: Multi-component induction measurements are made using a resistivity logging tool in an anistropic earth formation. A subset of the multi-component measurements are inverted to first determine horizontal resistivities. Using the determined horizontal resistivities and another subset of the multi-component measurements, the vertical resistivities are obtained. Results of using the in-phase signals are comparable to those obtained using multifrequency focusing of quadrature signals.
