  • Patent number: 8628961
    Abstract: Disclosed are new members of a class of non-lipid small molecule inhibitors which interfere with the interaction between phosphoinositol-3,4,5-triphosphate (PIP3) and pleckstrin homology (PH) domains. These molecules target a broad range of PIP3-dependent signaling events in vitro and exert significant anti-tumor activity in vivo, with improved activity and selectivity toward particular PH domains. The small molecule inhibitors of the invention can be used alone or together with tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) or other cancer medicament to treat cancer. Small molecule inhibitors of the invention act synergistically in combination with TRAIL and with other Akt inhibitors in treating cancer. Pharmaceutical compositions and methods for treating cancer are provided.

  • Patent number: 8574461
    Abstract: A method of manufacturing a biopolymer optical device includes providing a polymer, providing a substrate, casting the polymer on the substrate, and enzymatically polymerizing an organic compound to generate a conducting polymer between the provided polymer and the substrate. The polymer may be a biopolymer such as silk and may be modified using organic compounds such as tyrosines to provide a molecular-level interface between the provided bulk biopolymer of the biopolymer optical device and a substrate or other conducting layer via a tyrosine-enzyme polymerization. The enzymatically polymerizing may include catalyzing the organic compound with peroxidase enzyme reactions. The result is a carbon-carbon conjugated backbone that provides polymeric “wires” for use in polymer and biopolymer optical devices. An all organic biopolymer electroactive material is thereby provided that provides optical functions and features.

  • Publication number: 20130258281
    Abstract: An adaptor adapts an SLR camera for use as an ophthalmic viewing and imaging device. The adaptor is mounted to the camera between the camera body and the camera lens, and includes optical components arranged to direct illumination of the interior of the eye. The adaptor includes a first light source configured to provide a maximum level of illumination that is sufficient to identify structures of interest within an interior of an eye. The adaptor directs light from a second, external source to provide a level of illumination sufficient to obtain a fundus image. Optical components within the adaptor define a first optical pathway for directing light from the first light source to the lens, a second optical pathway for directing light from the second light source to the camera lens, and a third optical pathway for directing light from the camera lens through the adaptor to the camera.

  • Publication number: 20130245716
    Abstract: The regenerative sleeve encompasses the wound site of an amputated appendage and provides an environment conducive to tissue regeneration. The sleeve includes a tubular reservoir having an outer body that encloses the end of the appendage including the wound site and provides a sealed wound space between the wound site and the outer body. The sleeve also includes a cuff disposed in an opening formed in the outer body, the cuff being configured to fit on the appendage, and an access port disposed on the outer body and configured to allow administration of fluids to the wound space.

  • Patent number: 8437551
    Abstract: A system that extracts text from an image includes a capture device that captures the image having a low resolution. An image segmentation subsystem partitions the image into image segments. An image restoration subsystem generates a resolution-expanded image from the image segments and negates degradation effects of the low-resolution image by transforming the image segments from a first domain to a second domain and deconvolving the transformed image segments in the second domain to determine parameters of the low-resolution image. A text recognition subsystem transforms the restored image data into computer readable text data based on the determined parameters.
