    摘要: A single celled organism, vector, and method are provided for continuous production of excreted proteins in the absence of substantial host cell replication and without the necessity for the addition of antibiotics to control cell replication. The vector has (1) an inducible promoter capable of activating a gene for a protein to be produced under conditions that substantially inhibit host cell replication, and (2) a hybrid gene containing a signal sequence fused to a gene for the protein to be produced. Large quantities of the transformed single celled organisms containing the vector can be grown in the absence of inducing conditions, thereby reducing the problem of plasmid loss. Further, the protein is produced under conditions that substantially inhibit host cell replication, thereby allowing immobilization of the single celled organism by entrapment or attachment within or onto a solid support surface. The single celled organism can be immobilized after, before or simultaneously with induction. The single celled organism advantageously may be an encapsulated gram-negative bacterium which has no outer membrane or an outer membrane that is permeable to the proteins to be produced so that the protein products are excreted into the media thereby avoiding difficulty in recovering the desired protein products due to the formation of inclusion bodies or the presence of contaminants produced by cell lyses.

    摘要: Method, system, and computer-readable medium are provided for optimizing an allocation of money to assets and liabilities. A method includes providing at least one asset comprising a value and a projected return rate at which the value is expected to appreciate over a period, providing at least one liability including a liability amount and an interest rate at which the liability amount is expected to depreciate over said period, and optimizing an allocation of money to the at least one asset and the at least one liability based on the expected appreciation of the at least one asset and the expected depreciation of the at least one liability.

    摘要: Nucleotide sequences, derived from a thermophilic actinomycete microorganism, which encode a thermostable alkaline protease are disclosed. Also disclosed are variants of the nucleotide sequences which encode a polypeptide having thermostable alkaline proteolytic activity. Recombinant thermostable alkaline protease or recombinant polypeptide may be obtained by culturing in a medium a host cell genetically engineered to contain and express a nucleotide sequence according to the present invention, and recovering the recombinant thermostable alkaline protease or recombinant polypeptide from the culture medium.

    摘要: Described is a medical device and method for allowing fenestration of the aortic wall while maintaining distal perfusion and preventing external bleeding. The device isolates a segment of the aortic wall from the flowing column of blood using a balloon mounted on a metal alloy strut assembly. The strut assembly expands radially from a collapsed, low-profile configuration when uncovered by a constraining outer sheath. Aortic blood flow is allowed through the flow passage thus contained by the strut assembly within the center of the balloon. The balloon is inflated to contact the aortic wall. The balloon contains a pocket shaped to allow aortic fenestration. The balloon contains radiopaque markers to facilitate orientation and positioning of the pocket within the aorta. Other embodiments using spaced balloons are also disclosed.
