Abstract: A synthetic hemagglutinin (sHA) which represents the highest degree of conservation in the HA sequences of all Influenza B viruses (IVB) based on comprehensive bioinformatics analyses was cloned into an adenoviral vector. The recombinant adenovirus carrying the sHA gene was then delivered intransallyintranasally into DAB/2 mice. The animals were challenged with 5xLD50 influenza B viruses. We have found that the synthetic HA vaccines afford 100% protection against lethal challenge whereas 50% mice died in the control group. Furthermore, no virus was found in the lung of the vaccinated group while significant lung viruses were found in all mice of the controlled group. Consistent with the survival data and virus titre, severe pneumonia was found in all mice of the control group while no pathologic observation was made in animals receiving the vaccines.

Abstract: Two universally conserved sequences from influenza type A neuraminidases were identified by large scale sequence analysis then chemically modified and conjugated to carrier proteins to generate mono-specific and monoclonal antibodies. The two antibodies, one targeting the N-terminus of the type A neuraminidase and the other sequence close to enzymatic active site, were capable of binding to all 9 subtypes of neuraminidase while demonstrating remarkable specificity against the viral neuraminidase sequences since no cross-reactivity against allantoic proteins was observed. Quantitative analyses of NA using slot blot suggest that the antibodies can be used for NA antigen quantitation in vaccines. These represent the first time the antibody-based immunoassay can be used for NA quantitative determination.

Abstract: A fiber-coax unit (FCU) is coupled to an optical line terminal (OLT) and a plurality of coax network units (CNUs). The FCU receives a multicast frame from the OLT. The multicast frame includes a first multicast logical link identifier (LLID) dedicated for multicast traffic directed to CNUs. The FCU replaces the first multicast LLID in the multicast frame with a second multicast LLID corresponding to one or more multicast groups that include at least one CNU of the plurality of CNUs. The FCU transmits the multicast frame to the plurality of CNUs.
