    摘要: Embodiments of the present invention provide a method and a system for implementing multicast using a slave block in DSL access technique. Several slave blocks are cascaded with a master block accessed to the DSL. The master block and slave block are respectively connected with DSL users via RTUs, and access an uplink via a network interface of the master block. The slave block is configured to support the IGMP proxy or the IGMP snooping so as to implement multicast function independently. This invention overcomes the shortcomings including the heavy burden on the master block, low efficiency and serious waste in bandwidth resulting from the fact that the operation of the slave block multicast member is implemented in the master block, thus increasing the efficiency of multicast and saving bandwidth of the master block.

    摘要: The present invention relates to genes and genes clusters which are expressed in a tissue specific maner. For example, the invention relates to a group of genes encoding GPCR-like receptors that are involved in the function and activity of the immune system. These genes are organized into a discrete cluster at chromosomal location 1q22 (the “immune gene complex”) and span about 700 kb of DNA. The region closest to the centromere comprises genes that are expressed predominantly in the thymus, while the distal region comprises genes which are expressed predominantly in the bone marrow and other hematopoietic cells. Another cluster of GPCR genes is located at chromosomal band 11q24. These genes are expressed predominantly in pancreatic tissue, establishing this region of chromosome 11 as a unique gene complex involved in pancreatic function. A cluster of transmembrane and GPCR-type receptor genes is also located at chromosomal band 11q12.2. These genes are expressed predominantly in the spleen (hence, “spleen gene” cluster), as well as other tissues of the immune and reticuloendothelial system (RES), indicating that establishing this region of the chromosome is involved in spleen, lymphoid, and/or reticuloendothelial function. Finally, genes coding for membrane proteins have been identified which are expressed selectively in bone marrow, kidney, pancreas, and retina.
