Abstract: F gene-deficient virus virions are successfully recovered by using an F gene-deficient Sendai virus genomic cDNA. Further, F gene-deficient infectious viral particles are successfully constructed by using F-expressing cells as helper cells. Also, F gene and HN gene-deficient virus virions are successfully recovered by using a virus genomic cDNA deficient in both F gene and HN gene. Further, F gene and HN gene-deficient infectious viral particles are successfully produced by using F- and HN-expressing cells as helper cells. A virus deficient in F gene and HN gene and having F protein is constructed by using F-expressing cells as helper cells. In addition, M gene-deficient infectious virus particles were produced using helper cells expressing M protein. From cells infected with M gene-deficient viruses, release of virus-like particles was inhibited. Further, a VSV-G pseudo type virus is successfully constructed by using VSV-G-expressing cells.

An RNP comprising a foreign gene is prepared and inserted into a cell with the use of a cationic liposome, thereby successfully expressing the foreign gene.

Abstract: In relation to a blade cutting stone or concrete, a blade, preventing wearing of a core while preventing the core from wobbling, cuttable at a stable speed is provided. In a blade formed by providing slots on the outer peripheral edge of a circular core and fixing a superabrasive layer to a portion of the outer peripheral surface of the core located between the slots, the superabrasive layer consists of a first superabrasive layer having an extension formed by partially extending the superabrasive layer toward the inner periphery of the core and a second superabrasive layer.

Abstract: A superabrasive wheel (100, 200) for mirror finishing includes an annular base plate (120, 220) having an annular end surface (121, 221) and a plurality of superabrasive members (110, 210), each having a peripheral end surface (111), arranged along the periphery of the annular base plate (120, 220) at intervals from each other in a circumferential direction and fixed onto the end surface (121, 221) of the base plate (120, 220).

Abstract: A POF cable line which comprises a steel pipe and three cable cores drawn in the steel pipe. At least one curved offset section is arranged on the steel pipe at a part spaced from a cable joint at a predetermined distance, with a straight portion of the steel pipe interposed therebetween. The curved offset section prevents the cable cores in the part of the steel pipe from snaking hard and consequently prevents the insulation paper in the part from making soft spots or creases. The snaking occurs easily in the offset section when the cable core thermally expands.
