  • Publication number: 20150276864
    Abstract: A dual-phase interferometric method and device for charge modulation mapping in integrated circuits provides significant improvement in signal to noise ratio over conventional detection configurations. The method and device can be used for failure analysis and testing of advanced technology IC chips for which high sensitivity in modulation mapping is required.

  • Publication number: 20150185474
    Abstract: A system and method for correction of aberrations in a solid immersion microscopy system using a deformable mirror. A solid immersion lens is provided having a surface configured to make optical contact with a nearly planar surface of a substrate, an object to be imaged disposed on the opposite side of the substrate. A convex surface of the solid immersion lens faces an objective lens. A deformable mirror assembly, including a plurality of individually controllable actuators, receives light transmitted from the object. A control system controls in communication with the deformable mirror assembly provides individual actuation of each of the actuators of the deformable mirror to compensate or counteract the effects of aberrations.

  • Patent number: 8709474
    Abstract: The present invention relates to the use of copper ions to achieve enhanced retention of a therapeutic agent within a liposome. The invention may be employed to more effectively deliver a liposomally encapsulated therapeutic agent to a target site in vitro and in vivo for anti-cancer or other therapy. The liposome may comprise an interior buffer solution containing the therapeutic agent, the solution having a pH less than 6.5 and most preferably approximating pH 3.5. At least some of the copper ions are retained within the interior solution. In a particular embodiment the therapeutic agent may be a chemotherapeutic drug, such as irinotecan. The invention may also comprise an ionophore to facilitate loading of drug into the liposome. In one particular embodiment the combination of the ionophore A23187 and encapsulated divalent copper (Cu2+) resulted in an irinotecan formulation that exhibited surprisingly improved drug retention attributes.

  • Publication number: 20080213183
    Abstract: The use of the maximum tolerated dose (MTD) of individual drugs to determine appropriate administration ratios of drugs for combination therapy, wherein the ratios of drugs are fixed based on the same percentage of the MTD for each drug. Furthermore, antineoplastic compositions comprising liposomal encapsulated gemcitabine alone or in combination with free or liposomal encapsulated antineoplastic agents, such as idarubicin, irinotecan, etopside, cisplatin, cyclophosphamide, doxorubicin, or vincristine are diclosed.
