Abstract: It is an object of the present invention to provide a demethylation method that, from among multiple methylated regions present in the genome DNA of a living cell, can demethylate a specified methylated region only without influencing the other methylated regions, and to achieve the object, a target methylated region present in either a sense or antisense DNA chain in genome DNA of a living cell is demethylated, by artificially generating in the living cell the following (a) RNA comprising a base sequence equivalent to the base sequence of a region comprising all or part of the target methylated region in the DNA chain where the target methylated region is present, or (b) RNA comprising a base sequence equivalent to the base sequence of a region comprising a region neighboring the target methylated region in the DNA chain where the target methylated region is present.

Abstract: A plastic pallet including a square upper plate part and lower plate part, and columns connecting the upper plate part and the lower plate part. Fork insertion apertures are formed between the columns in the side faces of the pallet. Rectangular reinforcing frames are multiply formed surrounding the cross-section of the fork insertion apertures orthogonal to the fork insertion direction, and a hollow portion is formed inside these reinforcing frames, along at least three sides of the reinforcing frame.

Abstract: This synthetic resin pallet has a load portion 1 and a plurality of leg portions 2 protruding downward from the load portion 1 with fork inserting portions 4 provided between the leg portions 2. The load portion 1 comprises a horizontal plate portion and a grating portion 6 formed by intersection of a plurality of vertical ribs 6a, 7a and a plurality of horizontal ribs 6b, 7b, provided at a bottom of the horizontal plate portion. The leg portions 2 are so formed as to protrude downward from a lower end of the grating portion 6. Each of the leg portions 2 comprises a plurality of small leg portions 3 that are separated by a plurality of parallel vertical ribs 7a and/or a plurality of parallel horizontal ribs 7b. Engagement holes 22 are formed in the small leg portions 3 and plate-like link portions 20 are attached by fitting engagement portions 24 in the engagement holes. Recesses in which the small leg portions 3 are to be fitted are formed in the plate-like link portions 20.

Abstract: This plastic pallet comprises a square upper plate part 1 and lower plate part 2, and columns 3, 4 and 5 connecting the upper plate part 1 and the lower plate part 2. Fork insertion apertures 6 are formed between the columns 3 and 4 in the side faces of the pallet. Rectangular reinforcing frames 70 are multiply formed surrounding the cross-section of the fork insertion apertures 6 orthogonal to the fork insertion direction, and a hollow portion 70′ is formed inside these reinforcing frames 70, along at least three sides of the reinforcing frame 70.
