  • Publication number: 20100186126
    Abstract: The present invention provides methods and compositions for the production of recombinant plasminogen, microplasminogen, and fragments thereof in a duckweed expression system. It is the novel finding of the present invention that a duckweed expression system may be used to produce high levels of plasminogen and microplasminogen. The duckweed-produced plasminogen and microplasminogen can be activated to produce a polypeptide having protease activity. Thus, the invention encompasses methods for the expression of plasminogen, microplasminogen, and fragments thereof in duckweed, duckweed plants that are transformed with expression cassettes for the expression of plasminogen, microplasminogen, and fragments thereof, and nucleic acids comprising nucleotide sequences encoding plasminogen, microplasminogen, and fragments thereof, where these nucleotide sequences are modified to enhance their expression in duckweed.

  • Publication number: 20100152770
    Abstract: A bleed out prevention system and method includes an adjustable length attachment belt assembly which is passed around the body of a human being suspected of having an injured or severed major blood vessel. The adjustable length attachment belt assembly positions a plunger plate assembly over a location where compressive force can be applied to a portion of the major blood vessel which has not been injured or severed. A compressive force application assembly then applies force which reduces the size of the lumen in the major blood vessel thereby restricting or stopping the flow of blood therethrough.

  • Patent number: 7706535
    Abstract: A quantum cryptographic key distribution (QKD) relay (205) includes one or more interfaces (530-1 through 530-N) and processing logic (505). The one or more interfaces (530-1 through 530-N) receive secret keys from other QKD relays in a QKD network. The processing logic (505) determines one or more paths for transporting the secret keys, using quantum cryptographic techniques, across a QKD network and route the secret keys towards a respective destination across the QKD network using the determined one or more paths.

  • Patent number: 7632983
    Abstract: Methods, nucleic acid sequences, and transformed duckweed plant or duckweed nodule cultures for the expression and the secretion of biologically active polypeptides from genetically engineered duckweed are provided. Expression of recombinant polypeptides in duckweed is improved by modifying the nucleotide sequence of the expression cassette encoding the polypeptide for improved expression in duckweed. Recovery of biologically active polypeptides from duckweed is improved by linking the biologically active polypeptide to a signal peptide that directs the secretion of the polypeptide into the culture medium. Methods of producing recombinant monoclonal antibodies having effector function, and antibodies produced by these methods are provided.

  • Patent number: 7512242
    Abstract: A system transports a key between a first node (505) at one end of a path (500) through a quantum cryptographic key distribution (QKD) network to a second node (525) at an opposite end of the path (500), where the QKD network includes multiple nodes. The system transmits secret bits between the multiple nodes of the QKD network using quantum cryptographic mechanisms. The system reserves (530), from the first node (505), portions of the transmitted secret bits at each intermediate node along the path between the first (505) and the second node (525). The system transports a key between the second node (525) and the first node (505) using the reserved portions (555, 560, 565, 575) of the transmitted secret bits.
