Abstract: A tubular woven fabric is useful as a transport hose for a fluid or a powder, as a protective hose for linear bodies such as wires, cables and conduits, as a tubular filter, or as a base material of a vascular prosthesis. The tubular woven fabric includes warp yarns and weft yarns interwoven with each other, the tubular woven fabric having an outer diameter with a variation of within 10% along the warp direction and satisfying the formula: (L2?L1)/L1?0.1.

Abstract: A biodegradable block copolymer has high conformability and excellent degradability. The block copolymer including a polyalkylene glycol block and a polyhydroxyalkanoic acid block, wherein the mass ratio of the polyalkylene glycol block with respect to the total mass is 10 to 60%; the carbonyl carbon has a carbon nuclear relaxation time T1? of not more than 20 ms; and the block copolymer satisfies Equation (1): ?=?1×?2>20 (1) ?1: crystallization rate of the polyalkylene glycol block; ?2: crystallization rate of a poly-A block, wherein A represents, among the repeat units contained in the polyhydroxyalkanoic acid block, a repeat unit whose homopolymer composed of the same repeat units has a highest crystallization rate.

Abstract: A peptide consisting of an amino acid sequence represented by any one of SEQ ID Nos. 1 to 76 of the present invention, a peptide consisting of an amino acid sequence in which one or several amino acids are substituted, deleted, inserted or added in these amino acid sequences, and having an ability to bind to, or to be taken into an activated vascular endothelial cell, or a peptide containing the above peptide as a partial sequence, and having an ability to bind to, or to be taken into an activated vascular endothelial cell is a novel peptide ligand specifically binding to a neovascular endothelial cell, and such a ligand can be effectively used for treating and diagnosing a disease accompanying vascularization such as a solid tumor.

Abstract: A pharmaceutical preparation has a ligand structure specifically recognizing a target site and an amphiphilic compound having a hydrophobic or amphiphilic group. The pharmaceutical preparation employs an amphiphilic compound of specific structure obtained by introducing a chained hydrophilic group with an appropriate flexibility, and thus becomes a fine particle suited for drug targeting. The pharmaceutical preparation is expected to give a prolonged pharmacological effect. A particulate preparation exhibiting a remarkable site targeting property can be formed. Further, according to the selection of matrix forming material, the drug releasing property can be controlled.
