Abstract: A top-loading multi-axial, double locking bone anchor assembly. A receiver member receives an internal saddle member, a bi-polar member, and a bone anchor through an open bottom, which are retained by an internal threaded ring member threaded onto the receiver member. A double-locking compression retaining member includes an external nut-like fastener and an internal setscrew-like fastener. The nut-like fastener attaches to an upper portion of the receiver member and interfaces with the internal saddle member to retain a desired angular position on the bone anchor and the setscrew-like fastener interfaces with an elongated member placed in a channel of the receiver member to retain it to the assembly. The bone anchor is capable of multi-axial as well as multi-polar positioning with respect to the receiver member.

Abstract: The present invention provides conjugates useful for the diagnosis and treatment of diseases associated with the over-expression of COX-2.

Abstract: 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.
