Abstract:

The disclosure includes a composition including a poly(L-glutamic acid) and a NIRF dye. It also includes a method including providing to a plurality of cells an imaging agent including poly(L-glutamic acid), a NIRF dye and then imaging the cells to detect the imaging agent. It further includes a dual functional contrast agent including an MRI agent conjugated with an optical imaging agent. A method of detecting cancer is provided including injecting a dual functional contrast agent into a patient and performing both an MRI and an optical scan. The presence of the agent may indicate cancer. A method of detecting cancer by injecting PG-DTPA-Gd-NIR813 into a patient, then detecting the presence or absence of Gd in a cell or tissue of the patient and detecting the presence or absence of NIR813 in a cell or tissue of the patient is provided. The presence of Gd and NIR813 may indicate cancer.

International Classification:

E21B 34/06
E21B 34/00

US Classification:

166373, 166321

Abstract:

A remote actuation tool equipped with an intermediate volumetric mechanism for enhanced tool durability in high pressure differential downhole environments. Valve segments of the tool are actuated by power available due to a pressure differential between atmospheric and hydrostatic chambers of the tool. Yet, the intermediate volumetric mechanism, whether in the form of a discrete chamber or a hydraulic line system, minimizes stresses of the differential pressure on tool hydraulics. Thus, failure rates are substantially reduced. So, for example, the tool may be reliably employed in downhole environments which present differential pressures in excess of about 30,000 PSI.

US Classification:

424 944, 548455, 424 96, 424 91

Abstract:

The present invention provides nonradioactive NIR optical imaging agents based up on the structure of retinoid acid derivatives. The nonradioactive NIR optical imaging agent has been evaluated at the cellular level by confocal microscopy, and in vivo in a whole animal using a various xenograft models. The specific uptake of this agent in human cancer cells and multiple xenograft models demonstrate that nonradioactive near infrared dye labeled retinoid metabolites and/or analogs are useful for early stage cancer studies and diagnoses. Also, the present invention provides that nonradioactive near infrared dye labeled retinoid metabolites and/or analogs are useful for visualization of drug redistribution within the body which is useful in determining the optimal biological dose. Ultimately, the visualization data can be used as an analytical tool to reduce any systemic toxicity.
