  • Patent number: 8394026
    Abstract: Described herein are a method and apparatus for determining viscoelastic parameters of a tissue. A vibration signal is applied to the tissue and displacements at a plurality of locations within the tissue are measured at a plurality of times. The viscoelastic parameters of the tissue, including elasticity and viscosity, can then be determined by fitting a finite element model of the tissue to the vibration signal and the measured displacements and by solving for the viscoelastic parameters of the model. A value for density of each element of the model is selected and the absolute values for the viscoelastic parameters of each of the elements in the model is determined. Alternatively, the difference in relaxation-times between two locations within the tissue can be determined from the difference in phases of the strains at the two locations.

  • Patent number: 8361981
    Abstract: Administration of antisense oligodeoxynucleotides (ODN) targeted against the testosterone-repressed prostate message-2 (TRPM-2) gene can reduce the amount of TRPM-2 in renal cell cancer (RCC) cells and other cancer cells, and as a result enhance chemosensitivity of these cells to chemotherapy agents and radiation. Thus, for example, the sensitivity of renal cell cancer cells to a chemotherapeutic agent can be increased by exposing renal cell cancer cells to a chemotherapeutic agent and an agent which reduces the amount of TRPM-2 in the renal cell cancer cells. This provides an improved method for treatment of renal cell cancer, which is generally resistant to treatment with known chemotherapy agents.

  • Patent number: 8352224
    Abstract: A 3D structure approximating a 3D curved surface having non-zero Gaussian curvature over a portion of the surface. The structure is formed of a plurality of thin strips (10) which are simply deformed and aligned adjacent one another to approximate the 3D curved surface. Each strip has: zero Gaussian curvature; a strip width which varies by no more than ±10% along a longitudinal axis of the strip; and a predetermined flat shape such that, after simple deformation, adjacent edges of adjacent strips can be aligned substantially parallel to one another separated by a substantially small gap. The aligned, simply deformed strips appear straight when viewed from a preferred viewing direction. The strips can be attached to a rigid support (12) at selected mounting points such that natural equilibrium deformation between the mounting points holds the aligned simply deformed strips in a desired approximation of the 3D curved surface.

  • Patent number: 8323199
    Abstract: The present invention relates to a method and apparatus for imaging the mechanical properties of a tissue region from within an endocavity of a patient. The apparatus generally comprises an ultrasound probe, a vibration assembly translationally coupled to probe and operable to vibrate the probe along a vibration plane, and a rotation assembly rotationally coupled to the vibration assembly and operable to rotate the probe and vibration assembly about a selected rotational range. The method generally comprises inserting an ultrasound probe into an endocavity of a patient, vibrating the probe along a vibration plane thereby causing deformational excitement of a tissue region contacted by the probe, capturing a first series of ultrasound images of the tissue region, rotating the vibration plane relative to the tissue region by a selected angular rotation, and capturing a second series of ultrasound images of the tissue region.

  • Patent number: 8322325
    Abstract: Disclosed is a method and corresponding fuel injector for injecting gaseous and liquid fuel into an engine. The method comprises delivering a liquid fuel to a fuel injector, delivering a pressurized gaseous fuel to the fuel injector, entraining the liquid fuel within the gaseous fuel within a chamber of the fuel injector and injecting the gaseous fuel and atomized liquid fuel into the combustion chamber. The liquid fuel can be passed through and dispensed from a needle into a chamber in the injector nozzle where it is entrained in the gaseous fuel during an injection event. The liquid/gas mass ratio is controlled by the needle movement, hydraulic resistances or electronic valves so that the majority of the liquid is injected during the first part of the gas injection. The injector can be used for late cycle direct injection of natural gas, or any number of gaseous fuel blends combined with many liquid fuels such as diesel, biodiesel and DME.
