    摘要: The invention concerns human interferon alpha and in particular modified forms of interferon alpha 2 with improved properties. The improved proteins contain amino acid substitutions at specific positions that confer increased relative activity in biological assays. The invention provides also modified interferon alpha with improved biological activity concomitant with reduced immunogenic potential in the protein. The improved proteins are intended for therapeutic use in the treatment of diseases in humans.

    摘要: A method and system for tracking data packets that utilizes a tree data structure with a recursive pruning algorithm that collapses the branches of the tree that represent contiguous ranges or regions to maintain a minimally optimum memory size. Each contiguous region is identified by a node, which includes the start and end range of packets. Each node further includes left and right pointer elements, which point to adjacent lower and higher nodes, respectively. When a packet sequence number is not contiguous with any other sequence numbers previously received, a new node is created that contains only a single value range. When a new packet is received that has a contiguous sequence number (i.e., immediately preceding or succeeding sequence number), the original node is updated so as to reflect the new contiguous range. Additionally, if this new contiguous range is contiguous with another node's range, the two nodes are “collapsed” into a new single node containing the new expanded contiguous range. Furthermore, the algorithm can quickly and efficiently determine whether there are any missing packets by simply determining if there is only a single node remaining after a designated “last packet” has been received.

    摘要: The present invention relates to polypeptides to be administered especially to humans and in particular for therapeutic use. The polypeptides are modified polypeptides whereby the modification results in a reduced propensity for the polypeptide to elicit an immune response upon administration to the human subject. The invention in particular relates to the modification of human interferon beta to result in proteins that are substantially non-immunogenic or less immunogenic than any non-modified counterpart when used in vivo.
