  • Patent number: 8435558
    Abstract: A method of targeted drug delivery and imaging using nonionic surfactant vesicles (niosomes) in combination with ultrasound is presented. Niosomes have potential applications in targeted drug delivery and imaging because of their ability to encapsulate therapeutic agents and their enhanced uptake by physiological membranes. The niosomes may be administered to the subject via catheter. Ultrasound may be used to mediate delivery non-invasively by altering the niosome membrane structure. Niosomes composed of polyoxyethylene sorbitan monostearate (Tween 61), cholesterol, and dicetyl phosphate were synthesized via a thin film hydration technique and used for encapsulation studies. Carboxyfluorescein dye (CF) was used as a drug model to demonstrate delivery. The amount of dye in the niosomes, the concentration of the vesicles, and their mean particle size after each 5 minute incremental exposure to ultrasound was monitored.

  • Patent number: 7541515
    Abstract: Increased expression of heterologous proteins in a plant is achieved by introducing the nucleotide sequence encoding the heterologous protein into a plant that has high oil seed content compared to low oil seed and/or is introduced into a plant having reduced alcohol soluble proteins in the endosperm. The nucleotide sequence may be introduced by direct transformation into the plant, or by direct transformation into another plant, and crossing with the high oil plant or plant have reduced levels of alcohol soluble protein in the endosperm. Further, the nucleotide sequences may be introduced into one or both of the high oil plant and the plant having reduced levels of alcohol soluble proteins, and the plants may be crossed to result in a progeny having even further increased expression levels of the heterologous protein.

  • Publication number: 20080050445
    Abstract: Taught herein is a drug-delivery system that includes encapsulating a therapeutic drug in a nanoparticle vesicle that is then embedded into a hydrogel network. The system allows for enhanced, two-fold control over the release rate of the drug. This technology will be particularly advantageous in treating malignant cancer cells such as those found in the brain. The invention will allow for decreased side effects and increased survival time in patients. This invention opens the door to other technological applications that require controlled release of chemical substances.

  • Publication number: 20070172520
    Abstract: An immunoniosmes for targeted delivery of therapeutic agents to specific tissues in a host and methods of synthesis of those niosomes. An antibody molecule having specificity for a target antigen, such as a cell surface marker or other marker differentially expressed on a target cell, is covalently coupled to a functionalized membrane constituent. In a particular embodiment the functionalized membrane constituent is polyoxyethylene sorbitan monostearate functionalized with cyanuric chloride. The niosomes of this invention thus provide a composition that enhances internalization or retention of the bioactive agent of the niosome into the cytoplasm of the cells of the target tissue by providing a high degree of target specificity. Furthermore, the membrane vesicle enhances the life of the therapeutic agent by preventing its degradation in the extracellular environment, while exhibiting lower toxicity than can occur with some liposomes.

  • Patent number: 7049484
    Abstract: Production of proteases in plants is set forth, whereby heterologous DNA encoding the protease is introduced into the plant and expression of the protein achieved. By such methods, expression is achieved in plants wherein the plant cell is not damaged, the protein can be recovered without contamination by other proteases, and can be expressed at levels such that commercial production of the enzyme is obtained. Expression levels can be at 0.1% of total soluble protein of the plant, or higher.
