  • Publication number: 20050143473
    Abstract: The subject invention provides materials and methods for treating allergy in animals. In a preferred embodiment, the invention provides methods for alleviating an animal's hypersensitive response to allergens, including, without limitation, migraine, asthma, allergic rhinitis, digestive disturbances, coeliac disease, conjunctivitis, urticaria, eczema, drowsiness, hyperactivity (in children), tinnitus, recurrent sinusitis and ear infections. Specifically exemplified herein is the use of a cysteamine compound to reduce the hypersensitive response in animals to allergens. In a preferred embodiment, oral administration of cysteamine hydrochloride to an animal diagnosed with an allergy can substantially reduce the animal's reaction to the allergen.

  • Publication number: 20050137125
    Abstract: The subject invention provides compositions and methods for treating diabetes in patients. In a preferred embodiment, the invention provides compositions methods for treating diabetes and/or preventing or alleviating complications associated with diabetes. Specifically exemplified herein is the concurrent administration of a cysteamine compound with at least one additional therapeutic agent to prevent and/or treat diabetes as well as prevent and/or treat complications associated with diabetes. In a preferred embodiment, oral administration of cysteamine hydrochloride with Metformin to a patient diagnosed with diabetes can substantially regulate the patient's glucose metabolism and insulin sensitivity.

  • Publication number: 20050089549
    Abstract: A fish feeding composition for improving the growth and/or health of fish comprises cysteamine or salts thereof and from 1 to 80 wt % of a carrier. The fish feeding composition is preferably added to a basal feed and then fed to the fish. Use of such a feed increases body weight and reduces death due to disease and adverse living conditions.

  • Publication number: 20030161472
    Abstract: A server-assisted computational method for computing the RSA cryptography is delineated in this document. The method enables public-key functions on the resource-constrained devices, such as a mobile phone or a PDA, by leveraging the rich computing resources provided by the server-grade computers on the network. Public-key processing, which is computationally intensive as commonly known, if loaded solely on the constrained device, would easily overwhelm the processor capacity and electrical power supply. The server-assisted method enables such device to drive a powerful server computer on the Internet to carry out the public-key number-crunching job for its sake. Some near-completion results are communicated back to the device. From that, the final public-key cryptograph is derived. Privacy and security are the utmost important considerations in public-key systems. The present invention ensures the privacy of the device by blinding the server of the secret message and the crypto keys of the device.

  • Patent number: 6260409
    Abstract: Methods are described for measurement and prediction of site specific scour around a structure obstructing a flow. Representative soil samples are collected from an area proximate the structure location and tests are conducted on the samples to determine the erosion rate and hydraulic shear stress imposed. The maximum shear stress and initial scour rates around the structure are also obtained. Next, the maximum depth of scour is calculated, and the depth of scour versus time curve for the structure is then predicted. In a preferred embodiment, the methods described are used to predict a scour depth versus time curve around a cylindrical bridge support standing in the way of a constant velocity flow and founded in a uniform cohesive soil. An erosion function apparatus is also described which can be used to test representative samples of soil in the area where a structure is located.
