Abstract:
Methods for preventing, delaying the onset of, or treating rejection of an allograft using a DNA vaccine, where the vaccine can comprise a polynucleotide encoding a pro-apoptotic protein, like BAX and/or a polynucleotide encoding an autoantigen or donor antigen, like secreted glutamic acid decarboxylase 55. Administering one of the DNA vaccines to a transplant recipeint, as described herein, can induce a donor specific tolerogenic response.
Abstract:
Compositions and methods of treatment are provided for preventing cancers caused by high-risk human papilloma viruses (HPV). Cancers amenable to prevention include cervical cancer, head cancers, neck cancers, and oral cancers. The compositions block interaction between HPV 16 E6, one of two major viral oncogenes, and its partners, thereby resensitizing HPV positive cells to apoptosis.
Abstract:
An imaging system can use high-energy electrons at a low dose level to generate 3D computed tomography images and/or 2D radiographic images of living tissue and other objects. In some embodiments, a nozzle directs a source of high-energy electrons to the imaging target, and a detector system detects physical quantities of electrons that interact with the imaging target. In some embodiments, a computer system can calculate estimated paths taken by individual electrons within the imaging target, determine interactions between voxels of a digitized image of the imaging target and individual electrons, and reconstruct a digitized image of the imaging target based at least in part on the determined interactions between individual electrons and voxels. The imaging target can include but is not limited to living tissue, humans, pediatric patients, small animals, and other objects, such as those used in industrial applications.
Abstract:
Mammalian host cells for use in a cell-mediated transfection process, which contain an RNAi molecule and an expression vector for a pro-apoptotic protein. The method includes inducing apoptotic cell (AC) death in mammalian cells that contain an RNAi molecule capable of down-regulating a chosen target gene. Living cells expressing the target gene are then exposed to the ACs. The ACs are processed by the living cells, and the RNAi molecule in the ACs down-regulates the expression of the target gene in living cells.

Abstract:
A method of analyzing a medical image, where the medical image comprises one or more than one region of interest, and where the method comprises a) providing the medical image comprising a set of actual image values; b) rescaling the actual image values to produce corresponding rescaled image values and to produce a rescaled image from the rescaled image values; c) deriving a histogram of the rescaled image values; d) using the histogram to derive an adaptive segmentation threshold; e) using the adaptive segmentation threshold to recursively split the rescaled image; f) terminating the recursive splitting of the sub(sub) images using one or more than one predetermined criteria; and g) identifying one sub(sub) image in the terminated Hierarchical Region Splitting Tree which comprises the region of interest.
