Abstract: Sunlight redirector (30) incorporates closely proximate mirror arrays (32, 34) having parallel, uniformly spaced, longitudinal mirror segments (38, 44). Prismatic sheet (36) is positioned behind and closely proximate second array (34). Segments (38) extend in first direction (x). Segments (44) extend in second direction (y) perpendicular to direction (x) segments (38, 44)have normal vectors (42, 48). Segments (38) are interconnected for simultaneous pivotal movement (40), such that their normal vectors (42) remain parallel. Segments (44) are interconnected for simultaneous pivotal movement (46), such that their normal vectors (48) remain parallel. Arrays (32, 34) redirect incident light toward sheet (36), which redirects the light into a desired fixed direction, e.g. parallel to the sunlight redirect's normal vectors (50). Segments (38, 44) may have inward and outward segments (60A, 60B) which can be adjustably positioned to maximize redirection of incident sunlight rays in a desired direction.

Abstract: The embodiments described herein relate generally to an elastography method and system for obtaining ultrasound images of an excited tissue over a certain time period, then computationally determining one or more mechanical properties of the tissue within a real time refresh rate. This method can perform elastography in real time as only a thin volume of the excited tissue is imaged and processed. The thin volume includes a desired cross-sectional plane of the tissue and at least two adjacent planes that are adjacent to the desired cross-sectional plane. A maximum number of adjacent planes is selected so that a computer system is capable of computationally determining mechanical properties within a real time refresh rate.

Abstract: Particles of interest such as DNA, RNA may be detected in trace quantities by subjecting the particles to concentration by scodaphoresis, detecting a signal indicative of the presence of the particles in a scodaphoresis focus spot and performing phase-sensitive detection on the signal using a reference signal tied to the scodaphoresis fields. Specificity may be enhanced by using a medium having high affinity for the particles and/or markers having specific affinity for the target particles. In some embodiments a fluorescence signal is detected and subjected to phase-sensitive analysis. The signal may be detected by a camera or other imaging system.

Abstract: Particles may be injected into a matrix for concentration by scodaphoresis using a quadrupole injection field. Particles may be injected from two or more sample chambers simultaneously. Particle injection may be performed simultaneously with performing scodaphoresis. In some embodiments the particles are concentrated into a well containing fluid. The well can extend out of a plane of the matrix. Altering the relative phases of components of a scodaphoresis field permits concentration of selected particles and exclusion of other particles. Scodaphoresis methods may be applied to DNA, other bio-molecules and other particles.

Abstract: Agents that reduce the amount of IGFBP-2 and/or IGFBP-5 and that are known to be useful in the treatment of cancer result in increased expression of the protein clusterin. Since clusterin can provide protection against apoptosis, this secondary effect detracts from the efficacy of the therapeutic agent. In overcoming this, the present invention provides a combination of therapeutic agents that is useful in the treatment of cancer. The combination includes an agent that reduces the amount of IGFBP-2 and/or IGFBP-5 and that stimulates expression of clusterin as a secondary effect, and an oligonucleotide that is effective to reduce the amount of clusterin in cancer cells. In some embodiments of the invention, the agent that reduces IGFBP-2 and/or IGFBP-5 is a bispecific antisense species. The oligonucleotide may be an antisense oligonucleotide or an RNAi oligonucleotide.

Abstract: A method of recovering copper from chalcopyrite concentrate by chemical leaching, using pyrite and silver. The catalytic properties of pyrite in the chalcopyrite leaching process are significantly enhanced by pretreating the pyrite with silver ions. Particulate pyrite is exposed to a solution containing silver ions to form silver-treated pyrite. Particulate chalcopyrite and the silver-treated pyrite are mixed in an acidic sulfate leach solution. The copper is leached from the concentrate in the leach solution in the presence of an oxygen-containing gas, under conditions whereby the pyrite is substantially unoxidized. The leached copper is recovered from the solution by conventional methods. The used silver-treated pyrite is recycled to the leaching process.
