Abstract: This invention relates to multifunctional detection agents useful for providing high-resolution, in vivo imaging of biochemical activity in a living organism. Methods of using these multifunctional detection agents may comprise administering them into a living organism, and then estimating the localization of the detection agent using one modality (i.e., MRI), while concurrently estimating the level of biological activity using a second modality (i.e., optical imaging). One of the multifunctional detection agents comprises a magnetic resonance component and an optical imaging component. The magnetic resonance component comprises a contrast agent that is always activated or “on”. The optical imaging component comprises a plurality of activatable contrast agents or dyes, at least two of which are different from one another, wherein at least one of the activatable contrast agents can be activated or turned “on” only in the presence of a particular event.

Abstract: The present invention relates to the isolation of human stem cells for use e.g. in cell therapy. More specifically, the invention is a method of separating mononuclear cells from human blood, which method comprises providing a human blood sample together with density gradient media (DGM) in a container; spinning the container comprising blood and DGM; and collecting the DGM fraction that comprises mononuclear cells; wherein the DGM has a density which is >1.080 and <1.090 g/cm3 as measured at 25° C. The invention also relates to bags and tubes which contain density gradient media wherein the density and osmolality has been optimized for use in the present method, preferably as kits.

Abstract: A method for synthesizing extended poly(amino acids) conjugated to imaging agents, such as DTPA, is disclosed. The amino acid is initially conjugated to the imaging agent at the monomer stage, followed by formation of the corresponding N-carboxyanhydride. The method utilizes catalyzed ring opening polymerization of the N-carboxyanhydride of the amino acid-imaging agent monomer allowing the formation of a poly(amino acid) backbone having 100% imaging agent conjugation if desired. However, the present method also permits the degree of conjugation to be controlled by copolymerizing the N-carboxyanhydride of the amino acid-imaging agent monomer with one or more unconjugated monomers, i.e. N-carboxyanhydrides of the same or of other amino acids. Various imaging agents may be employed, and new hybrid random, block, and mixed copolymers may be prepared.

Abstract: Magnetic resonance (“MR”) contrast-enhancing agents comprise poly(amino acid) backbone chain conjugated to chelating moieties that comprise a plurality of carboxylic acid groups that form coordination complexes with paramagnetic ions. A method for detecting atherosclerotic plaque areas comprises administering at least one of these contrast agents into a subject; and obtaining and comparing MR images of and MR signals from the plaque areas before and after administering the contrast agent. The method can be used to assess an effectiveness of a prescribed course of treatment for atherosclerosis.

Abstract: An energy-consumption predicting system remotely measures amounts of energy consumed by energy-consuming systems or an energy-consuming site; monitors and compares the real energy usage of the systems or site against expected or predicted values for energy consumption; analyzes and determines likely causes for variances between the real and the predicted values; and recommends to the energy user actions for achieving optimum operation of the systems or site. The energy-consumption predicting system can also forecast the energy usage of the energy-consuming site. The predicted energy usage amounts are outputs of a transfer function that relates the amounts of energy consumed to the operating parameters and other energy-related variables of the energy-consuming systems or site. The energy-consumption predicting system also permits remote access and interaction by the user and allows for integrating energy-related information into an overall strategy for managing the energy-consuming site.
