  • Publication number: 20110236389
    Abstract: The invention provides human angiostatin interacting and tumor metastasis involving protein (HAI-TMIP) isoforms, namely HAI-TMIP variants 1 to 7, and human protein complexes comprising HAI-TMIP variant 1, 2, 3, 4, 5, 6 or 7. The invention also provides antibodies that immunospecifically bind to HAI-TMIP variant 1, 2, 3, 4, 5, 6 or 7 or a complex comprising such a variant, and uses of such antibodies. The present invention provides peptides which may be used as immunogens to distinguish between the HAI-TMIP variants. The invention further provides compounds that modulate the expression and/or activity of HAI-TMIP variant 1, 2, 3, 4, 5, 6 or 7, or a complex comprising such a variant, and uses of such compounds in the prevention, treatment and/or management of various disorders, in particular, cancer.

  • Patent number: 7822341
    Abstract: In one embodiment, a control method, according to which a cascade of control messages is propagated between nodes of an optically transparent network, with each message being sent from a node to an adjacent downstream node to inform the latter about a control operation scheduled to be performed at the message-sending node and/or an upstream node that impacts an optical communication signal received at that downstream node. The cascade of control messages effectively creates an ad hoc control domain, in which control operations performed at various nodes of that domain can be coordinated to reduce unfavorable interactions between those control operations. By repeatedly propagating appropriate cascades of control messages through the network, control domains can be changed dynamically and adaptively to reflect any changes to the network topology, equipment, and/or traffic distribution.
