Abstract: Microbial type rhodopsins, such as the light-gated cation-selective membrane channel, channel-rhodopsin-2 (Chop2/ChR2) or the ion pump halorhodopsin (HaloR) are expressed in retinal ganglion cells upon transduction using recombinant AAV vectors. Selective targeting of these transgenes for expression in discrete subcellular regions or sites is achieved by including a sorting motif in the vector that can target either the central area or surround (off-center) area of these cells. Nucleic acid molecules comprising nucleotide sequences encoding such rhodopsins and sorting motifs and their use in methods of differential expression of the transgene are disclosed. These compositions and methods provide significant improvements for restoring visual perception and various aspects of vision, particular in patients with retinal disease.

Abstract: A method to generate siRNAs in vivo is described, as are constructs and compositions useful in the method. The method does not depend on the use of DNA or synthetic constructs that contain inverted duplications or dual promoters so as to form perfect or largely double-stranded RNA. Rather, the method depends on constructs that yield single-stranded RNA transcripts, and exploits endogenous or in vivo-produced miRNAs or siRNAs to initiate production of siRNAs. The miRNAs or siRNAs guide cleavage of the transcript and set the register for production of siRNAs (usually 21 nucleotides in length) encoded adjacent to the initiation cleavage site within the construct. The method results in specific formation of siRNAs of predictable size and register (phase) relative to the initiation cleavage site. The method can be used to produce specific siRNAs in vivo for inactivation or suppression of one or more target genes or other entities, such as pathogens.

Abstract: A system for providing neurostimulation includes an external device (“external exciter”) and an implanted device. The external exciter includes an energy source which inductively powers the implanted device. Examples of such external exciters include devices having at least one of: ultrasonic transducers, Radio Frequency (RF) transmitters, and solar cells. The implanted device includes circuitry that limits its maximum energy output to a predetermined saturation threshold such that excess stimulation from the external exciter does not raise the output of the implanted device beyond the saturation threshold. The output signal of the external exciter is then pulse-width modulated in order to produce a desired amount of output stimulation from the implanted device to stimulate the bioelectrically excitable tissue at a desired level.

Abstract: Methods for forming a vertically movable gate field effect transistor (VMGFET) on a silicon-on-insulator (SOI) wafer are described. The methods include providing a process of making VMGFET devices without critical alignment of masks between sequential etch and diffusion steps. The oxide layer of the SOI wafer is used for a self-limiting etch stop layer and for a sacrificial layer to form an insulating layer between a gate electrode and a substrate. The proper location of the gate electrode with respect to the source and drain junctions is insured by using a silicon gate structure as a mask layer for the diffusion process for defining the source and drain junctions.

The method includes reacting a sugar having at least two nucleophilic moieties with at least two anchors, each anchor having at least one electrophilic moiety, to form the polymer. Alternatively, the method includes reacting a sugar having at least two electrophilic moieties with at least two anchors, each anchor having at least one nucleophilic moiety, to form the polymer. The anchors may be lipids or peptides. The sugar-anchor polymers stabilize lipid membranes against serum proteins, dehydration, and cryopreservation.

Abstract: Described herein are small peptide domains and consensus sequences that bind small target molecules of industrial importance, e.g., metals such as nickel, ? carotene, and isoflavones such as genistein. Also described are fusion proteins containing such binding domains fused to proteins or to peptide domains like GST or CBD that bind other ligands and can be used to immobilize the target binding domain on a support. One class of fusion proteins that is useful in industrial settings are fusions that contain concatemers of target binding domains, which increases the binding equivalents per molecule.
