Abstract: A method for forming a composite material that includes a product portion and a surplus portion formed on an end side of the product portion. The method includes placing in a forming jig having a forming surface the composite material before curing; and curing the composite material placed in the forming jig. The forming jig has a surplus forming section provided between the forming surface and the surplus portion. The surplus forming section is shaped in such a manner as to become thicker toward the outside of the composite material. The placing of the composite material includes mounting the surplus portion of the composite material on the surplus forming section to lift the surplus portion with respect to the product portion.

Abstract: A novel compound, which is effective for treatment of AIDS and has inhibitory activity on human immunodeficiency viruses (HIV), was examined. The K97-0003 peptide, which has anti-HIV activity caused by inhibition of syncytium formation by fusion of envelope glycoprotein of HIV and the host cells expressing the receptor to said virus, was provided by the present invention. Furthermore, the base sequence of the gene coding for said polypeptide, and the method for preparing said polypeptide using strain K97-0003 were provided.

Abstract: A laminated structure comprising a laminated foamed sheet material composed of two cured foamed sheets each comprising a propylene-type polymer and an ethylene-type polymer and being laminated to each other through a substantially non-foamed or lowly foamed heat-fused layer, and non-foamed surface skin layers composed of a propylene-type polymer and laminated respectively to both surfaces of said laminated foamed sheet material, the ratio of the thickness Ts of each of said surface skin layer to the solid thickness Tf of each of the cured foamed sheets, Ts/Tf, being from 1 to 50, the thickness T1 of the heat-fused layer being 0.1 to 0.5 mm, and the thickness T1 being 1 to 25% of the thickness of each of the cured foamed sheets.
