Abstract

This adhesive body attachment device (100) for pressing an adhesive body (2) against an object while delivering the adhesive body (2) from a wound body (11) comprises: a delivery assist mechanism (20) that applies an external force in a delivery direction to the adhesive body (2) delivered from the wound body (11); a pressing part (12) that presses the delivered adhesive body (2) against an object (W); and a detection unit (30) that detects whether or not a portion of the adhesive body (2) is at a position deviated from a prescribed path for conveying the adhesive body (2) from the delivery assist mechanism (20) to the pressing part (12) between the delivery assist mechanism (20) and the pressing part (12). The delivery assist mechanism (20) applies the external force in the delivery direction to the adhesive body (2) when the detection unit (30) detects that a part of the adhesive body (2) is not located at a position deviated from the prescribed path.

The purpose of the present invention is to provide: a double-stranded RNA for inhibiting the expression of both human YAP1 and human WWTR1; and a pharmaceutical composition comprising the same. This double-stranded RNA (dsRNA) for inhibiting the expression of both human YAP1 and human WWTR1 includes a sense strand and an antisense strand. The antisense strand includes a region complementary to a homologous sequence in a human YAP1 transcription product or in a human WWTR1 transcription product. The homologous sequence is a nucleotide sequence formed of 17 nucleotides in the human YAP1 transcription product, or is a nucleotide sequence formed of 17 nucleotides in the human WWTR1 transcription product. When the two nucleotide sequences are aligned, at least 14 nucleotides in consecutive 17 nucleotides are identical. Each of the strands has a length of at least 15 nucleotides. The sense strand and the antisense strand form a double-stranded region.

Abstract

Provided is an inter-cell structure which is suitable for maintaining a buffer function for relaxing stress from a lithium ion battery cell with high durability while achieving a size that is suited to the cell. Provided is an inter-cell structure for use in a battery module or a battery pack including a plurality of arrayed lithium ion battery cells, the inter-cell structure being disposed between adjacent cells among the plurality of cells. The inter-cell structure has: a bag body that defines a sealed space; and a fluid such as a gas and a porous sheet in the sealed space. The bag body is formed of a laminated film including a metal layer and a resin layer, and has a sealing end part in which the innermost layers of first and second film parts of the laminated film are joined to each other so as to seal the sealed space. The porous sheet is positioned at a distance from the sealing end part of the bag body. The bag body has, between the sealing end part and the porous sheet, a folded part in which the first and second film parts overlap with each other and are folded with the first film part being on the inner side.
