  • Patent number: 7479329
    Abstract: Hematin, a hydroxyferriprotoporphyrin, is derivatized with one or more non-proteinaceous amphipathic groups. The derivatized hematin can serve as a mimic of horseradish peroxidase in polymerizing aromatic monomers, such as aromatic compounds. These derivatized hematins can also be used as catalysts in polymerizing aromatic monomers, and can exhibit significantly greater catalytic activity than underivatized hematin in acidic solutions. In one embodiment, polymerization is in the presence of a template, along which aromatic monomers align. An assembled hematin includes alternating layers of hematin and a polyelectrolyte, which are deposited on an electrically charged substrate. Assembled hematin can also be used to polymerize aromatic monomers.

  • Publication number: 20080274195
    Abstract: The present invention discloses an improved nanoemulsion comprising a uniform and discrete range of very small particle nano-sized diameters. This uniformity results in improved bioavailability of incorporated compounds (i.e., pharmaceuticals or nutraceuticals) as reflected in various pharmacokinetic parameters including, but not limited to, decreased Tmax, increased Cmax, and increased AUC. The improved method of making these uniform nanoemulsions utilizes microfluidization which differs in both process and mechanics when compared to conventional milling and grinding techniques used to generate nanoparticulate compositions. Further, the improvement results, in part, from a novel step of mixing a substantially soluble compound into a heated dispersion medium. This is unlike current nanoparticulate composition methods that mix an insoluble compound with an unheated dispersion medium. Further, these nanoemulsions are observed to be bacterial-resistant and stable to extremes in both temperature and pH changes.

  • Publication number: 20080218732
    Abstract: Methods and systems for generating near-infrared (NIR) images of biological targets are discussed. In one aspect, one or more radiation sources illuminate a target, with one or more detectors receiving the transmitted radiation. Such equipment can be used to generate a plurality of NIR images of a target. The images can be converted into frequency space, combined using chosen weighting factors, and deconvoluted into the spatial domain to provide a composite image. The composite image can have enhanced quality relative to the individual images, allowing for a richer set of information to be displayed. Other aspects such as scanning, background illumination correction, the use of filters, and additional techniques are also discussed.

  • Publication number: 20060223946
    Abstract: According to an aspect of the present invention, a method is provided in which a double diphenylethylene compound is reacted with a polymer that contains a carbocationically terminated chain thereby providing a 1,1-diphenylene end-functionalized chain. Subsequently, an alkylating agent is reacted with the 1,1-diphenylene end-functionalized chain, thereby providing an alkylated 1,1-diphenylene end-functionalized chain. In some embodiments, the method further comprises (a) optionally combining a 1,1-diphenylorganolithium compound with the alkylated 1,1-diphenylene end-functionalized polymer followed by (b) reacting an organolithium compound with the alkylated 1,1-diphenylene end-functionalized polymer. This provides an anionically terminated polymer, which can be used, for example, in subsequent anionic polymerization and coupling reactions.

  • Patent number: 7031502
    Abstract: A guide can provide proper registration of an object such as a hand above a scanner device for imaging. The guide can include windows or slits so that the scanner device can produce an image such as a finger or palm in a natural state rather than being pressed against, for example, a flat surface such as glass. Thus, registration of a palm and/or a finger in the guide can be used to produce non-distorted high quality images of biometric patterns in their natural 3-dimensional state.

  • Patent number: 6961449
    Abstract: A method and apparatus for computing correlating images for image recognition is provided. In particular, the method is used to compare images of a biometric object to authorize an individual or verify whether an individual is the person he claims to be. The biometric objects may include fingerprints, hand or palm prints, and retina scans. The method uses a deviation of symmetry of correlation functions to determine whether the images are of a same object.
