Abstract:
The invention provides a method for improving the texture of a food product by incorporating in the food product or a precursor of the food product a bioelastic polypeptide in an amount sufficient to increase the elasticity of the food product, the bioelastic polypeptide having tetrapeptide or pentapeptide repeating units or mixtures thereof and the repeating units existing in a conformation having a beta -turn. The invention also provides a method for binding a food product precursor by adding a bioelastic polypeptide in an amount sufficient to bind the food product precursor, the bioelastomer having tetrapeptide or pentapeptide repeating units or mixtures thereof and the repeating units existing in a conformation having a beta -turn. The present invention further provides a food adjunct containing a bioelastic polypeptide having tetrapeptide or pentapeptide repeating units or mixtures thereof where the repeating units exist in a conformation having a beta -turn, and an edible material suitable for human or animal consumption.
Abstract:
A method for purifying an artificial polymer that exhibits a reversible inverse temperature transition is provided. The method involves (a) dissolving the polymer in an aqueous medium so that the temperature of the medium is below the effective transition temperature; (b) adjusting the temperature of the aqueous medium relative to the effective transition temperature of the polymer; (c) removing any particulate material from the medium; (d) adjusting the temperature of the aqueous medium relative to the effective transition temperature of the polymer so that the temperature of the medium is above the effective transition temperature; (e) collecting the polymer from the medium as a more dense phase; and (f) optionally repeating any of steps (a)-(e) until a desired level of purity is reached; with the proviso the order of steps can be (a)-(d)-(e)-(a)-(b)-(c).
Abstract:
This invention provides novel methods and compositions for use in the efficient and large-scale production of recombinant adeno-associated virus (AAV). Described herein are new producer cell lines, recombinant adenovirus or herpes virus vectors and AAV constructs. Also disclosed are particularly advantageous methods of using such materials to produce recombinant AAV virions using only the efficient process of viral infection, without requiring transfection steps. The AAV produced may be used in a variety of embodiments including, for example, for transferring exogenous genes into human cell lines and for use in human gene therapy regimens.
Abstract:
A monoclonal antibody directed against a novel cell adhesion molecule of glial cells has been developed. The glial cell adhesion molecule is characterized by a molecular weight of around 106 kDa. The antibody is specific for the glial cell adhesion molecule and is marked by an ability to disrupt the formation of gliotic scars in damaged nerve tissue.
Abstract:
A sequence specific DNA binding molecule which comprises an oligonucleotide conjugate formed by the covalent attachment of a DNA binding drug to a triplex forming oligonucleotide and a method of modulating gene expression comprising administering to a mammal in need thereof said sequence specific binding molecule.
Abstract:
Conjugates of β-D-xylose with estrogens or modified forms of estrogens are effective in stimulating the synthesis of heparan sulfate, and inhibiting the production of proteoglycan in animal subjects. Accordingly, these conjugates are useful in treating conditions where antithrombotic or antiproliferative activity is desirable.
Abstract:
A vascular prosthetic material having at least one layer containing an elastomeric material capable of reversibly contracting and relaxing by an inverse temperature transition. The vascular prosthetic material matches the compliance and elasticity of vessels replaced, and is biocompatible and biodegradable. The material may also have incorporated therein chemotactic peptides and cell attachment sequences.
Abstract:
An electrode terminal (12) is disclosed for delivering a stimulation pulse to the heart or other tissues containing a linear array of fibers (14). The electrode terminal (12) is elongated and adapted for orientation in a direction parallel to the tissue fibers (14). The device of the present invention further includes a power source (26) for electrically energizing the terminal such that the energizing of the terminal reduces the non-uniformity of the transmembrane voltage change in the tissue proximate the electrode which is produced during the stimulation pulse. Nonuniform transmembrane voltage changes are associated with arrhythmic conditions. The linear electrode of the present invention can be used for cardiac pacing, defibrillation, and the termination of tachycardia.
Abstract:
A superbroadband or multiwavelength laser transmitter source for wavelength-division multiplexing, two-wavelength interferometry, differential lidar and optical storage applications. The superbroadband laser (100) simultaneously emits at multiple wavelengths. The system maintains simultaneous lasing operation in an optical active gain medium at different wavelengths by the use of dispersive cavity. The system creates its own microcavities each lasing at a different wavelength within the fluorescence band of the gain medium. Mode competition in the cavity is absent and spectral range of simultaneous multi-frequency generation is considerably enhanced practically to the spectral width of the active media luminescence spectrum. As a result, the radiation of each mode with its own wavelength is amplified in the active media independently from the simultaneous amplification of the rest of the wavelengths.
Abstract:
Oral or peroral administration, including intragastrically, of killed whole pneumococci, lysate of pneumococci and isolated and purified PspA, as well as immunogenic fragments thereof, particularly when administered with an adjuvant such as cholera toxin provides protection in a host, animal or human, against pneumococcal infection, including colonization, and systemic infection, such as sepsis. The ability to elicit protection against pneumococcal colonization in a host prevents carriage among immunized individuals, wich can lead to elimination of disease from the population as a whole.
