  • Patent number: 8261420
    Abstract: The invention relates to a method and apparatus of reducing stress during stent manufacture. Particularly, the invention is directed to a method and apparatus for expanding a stent using primarily radial loads thereby reducing the stresses that are generated due to the axial loads applied during loading of the stent onto a mandrel or other expansion device. The method of the invention provides for the stepwise expansion of shape memory stents, while reducing the overall stresses that the stent encounters, and thereby improving manufacturing yields due to fractured struts during expansion.

  • Patent number: 8252754
    Abstract: The present invention relates to the discovery of a novel molecular pathway involved in long-term hyperexcitability of sensory neurons, which, in higher animals, is associated with persistent pain. It is based on the discovery that, following injury to an axon of a neuron, an increase in nitric oxide synthase activity results in increased nitric oxide production, which, in turn, activates guanylyl cyclase, thereby increasing levels of cGMP. Increased cGMP results in activation of protein kinase G (“PKG”), which then is retrogradely transported along the axon to the neuron cell body, where it phosphorylates MAPKerk.

  • Patent number: 8255688
    Abstract: Methods and systems for mutual authentication and personalizing a transaction device, such as a payment, transaction, or identity card. Successively generated one time codes are calculated by a first and second entity. One of the codes is transmitted to the second entity, which verifies the code is proper, then encrypts a second one time code using a third one time code and transmits the encrypted data to the first entity. The first entity decrypts the data using the third one time code, verifies the encrypted second one time code is proper, thereby mutually authenticating, and establishing a shared encryption key for subsequent communications, including transmission of personalization data.

  • Patent number: 8232449
    Abstract: The invention provides transgene constructs for expressing chimeric antibodies, and transgenic non-human host animals carrying such constructs, wherein the chimeric antibodies comprise human variable regions and constant regions of the non-human transgenic host animal. The presence of immunoglobulin constant regions of the host animal allows for generation of improved antibodies in such transgenic host animals. Subsequently, the chimeric antibodies can be readily converted to fully human antibodies using recombinant DNA techniques. Thus, the invention provides compositions and methods for generating human antibodies in which chimeric antibodies raised in vivo in transgenic mice are used as intermediates and then converted to fully human antibodies in vitro.
