Abstract: The present invention relates to: a virus vector, which can effectively transfer a macromolecular antigenic peptide into target cells while maintaining a three-dimensional structure that is required for functioning as an antigen; and a vaccine utilizing the vector. Specifically, disclosed are: a virus vector, in which a nucleic acid encoding an antigenic polypeptide is integrated immediately 5? upstream of HN gene of an F gene-defective Paramyxoviridae virus gene, wherein the antigenic polypeptide is expressed as a fusion protein of 130 or more amino acid residues, fused with a TM sequence and/or a CT sequence derived from the virus.

Abstract: The present invention relates to a rapid method for identifying a drug-resistant gene using an artificial chromosome of a protozoa. Specifically, it relates to a method for screening for a drug-resistant gene, which involves preparing a recombinant Plasmodium using an artificial chromosome of a Plasmodium, either inoculating the recombinant Plasmodium into a non-human mammal or using the in vitro culture system of the Plasmodium at the blood stage in the red blood cells, and using the survival of the recombinant Plasmodium in the presence of a drug as an index. The present invention also relates to a method for preparing a recombinant Plasmodium by directly introducing an exogenous gene into a Plasmodium at a high efficiency.

Abstract: The present invention provides Ti-4 protein, which is a protein obtained from salivary gland of Triatoma infestans, and the present invention provides Ti-4 gene encoding the protein. As the Ti-4 protein exhibits inhibitory activity on platelet aggregation, a medicine comprising the Ti-4 protein as an active ingredient will serve as a platelet aggregation inhibitor possibly effective for prevention and treatment of myocardial infarction, pulmonary infarction and cerebral infarction. Moreover, the Ti-4 protein will also serve as a highly prospective lead compound in the development of novel platelet aggregation inhibitors.

Abstract: Fan wheel comprising opposite end disks, intermediate disks interposed between the end disks at a specified spacing, and blades having a uniform section over the entire length thereof and extending through corresponding registered apertures formed in the outer peripheral portions of the disks. The apertures are circumferentially equidistantly arranged in each of the disks and coincide with the sectional shape of the blades. The blades are fixed with an adhesive to the disks at the portions thereof fitting in the disks.
