  • Publication number: 20100312039
    Abstract: Infusion system configurations and assemblies facilitate routing of infusion circuit tubing lines. Tubing lines are routed into and out from compartments of a shielding assembly for the infusion system, at locations which prevent kinking and/or crushing of the lines, and/or provide for ease in assembling the circuit. A plurality of the lines may be held together by a support frame to form a disposable infusion circuit subassembly, that can further facilitate routing of the lines.

  • Publication number: 20080300220
    Abstract: Disclosed herein is a class of linkable tetrasaccharide compounds that includes the amino phenyl glycoside of sialyl Lewis X (SLeX) and related analogs. These compounds have conjugatable nucleophilic groups, making them useful in preparing multimeric SLeX compositions. In particular, the disclosed SLeX compounds can be used to prepare selectin binding ligand conjugates by linking them to a reporter moiety, such as a contrast agent, a radiodiagnostic agent, or a cytotoxic or chemotherapeutic agent. The SLeX compounds and conjugates of the invention exhibit binding to selectin that is similar to native Sialyl LeX, and are, therefore, useful for diagnosing and treating selectin-mediated disorders and related conditions.
