Abstract: A sunlight redirector has a first mirror array formed of a first plurality of substantially parallel, uniformly spaced, longitudinal outward mirror segments; and a second mirror array formed of a second plurality of substantially parallel, uniformly spaced, longitudinal inward mirror segments. Each mirror segment has a normal vector. The outward mirror segments are adjustably positionable, such that their normal vectors remain parallel. The first mirror array is rotatable about a normal vector of the sunlight redirector. The inward mirror segments may remain fixed in position at all times; or they may be moved, twice per day, between first and second fixed positions.

Abstract: Displacement devices comprise a stator and a moveable stage. The stator comprises a plurality of coils shaped to provide pluralities of generally linearly elongated coil traces in one or more layers. Layers of coils may overlap in the Z-direction. The moveable stage comprises a plurality of magnet arrays. Each magnet array may comprise a plurality of magnetization segments generally linearly elongated in a corresponding direction. Each magnetization segment has a magnetization direction generally orthogonal to the direction in which it is elongated and at least two of the magnetization directions are different from one another. One or more amplifiers may be connected to selectively drive current in the coil traces and to thereby effect relative movement between the stator and the moveable stage.

Abstract: Isolated polynucleotides comprising a TNNT1 mini-promoters are provided. The mini-promoter may be operably linked to an expressible sequence, e.g. reporter genes, genes encoding a polypeptide of interest, regulatory RNA sequences such as miRNA, siRNA, anti-sense RNA, etc., and the like. In some embodiments a cell comprising a stable integrant of an expression vector is provided, which may be integrated in the genome of the cell. The promoter may also be provided in a vector, for example in combination with an expressible sequence. The polynucleotides find use in a method of expressing a sequence of interest, e.g. for identifying or labeling cells, monitoring or tracking the expression of cells, gene therapy, etc.

Abstract: Therapeutic agents which target heat shock protein (hsp) 27 in vivo are used to provide treatment to individuals, particularly human individuals, suffering from prostate cancer and other cancers that overexpress hsp27. A therapeutic agent, for example an antisense oligonucleotide or RNAi nucleotide inhibitor with sequence specificity for hsp27 mRNA, for example human hsp27 mRNA, is administered to an individual suffering from prostate cancer or some other cancer expressing elevated levels of hsp 27 in a therapeutically effective amount. The therapeutic agent is suitably formulated into a pharmaceutical composition which includes a pharmaceutically acceptable carrier, and packaged in dosage unit form. A preferred dosage unit form is an injectable dosage unit form.

Abstract: The invention provides apparatus for separation of particles and methods for using the apparatus. In an embodiment, the apparatus includes three arms extending radially from a central reservoir, each arm being associated with a separation electrode. At least one on the arms includes a separation medium. Using a sequence of driving and mobility-changing voltages, target particles can be separated from closely related particles within a sample. For example, single point mutations can be resolved from a sample containing predominantly wild type nucleic acids.
