Abstract: A method for manufacturing an additively-manufactured object in which deposition is performed by melting and solidifying a metal depending on three-dimensional shape data of a target shape, includes: acquiring the three-dimensional shape data; creating a deposition plan in which a formation track and a heating condition of the metal are determined; determining a difference between a shape of the additively-manufactured object that thermally contracts by cooling after deposition and a shape of the three-dimensional shape data by an operation; modifying the deposition plan until the difference falls within a predetermined allowable range; and additively manufacturing the additively-manufactured object based on the deposition plan in which the difference falls within the allowable range.

Abstract: The present invention has demonstrated that microorganisms present in a liver can be killed by washing the bile duct and the portal vein with hot water, and then disinfecting the liver using a chlorine-based disinfectant. It has also been demonstrated that sterilizing effects can be enhanced by freezing the liver after disinfection with a chlorine-based disinfectant.

Abstract: An objective of the present invention is to provide the cytolethal distending toxin (CDT) of C. hyointestinalis and polynucleotides encoding it, and novel methods for detection of C. hyointestinalis using the cdt genes. The present inventors focused on the cytolethal distending toxin (CDT) of Campylobacter bacteria, and detected the cdt genes of a Campylobacter-like bacterium isolated from an enteritis patient in Thailand. The present inventors discovered a bacterial strain whose cdtB gene was amplified by common primers in C. jejuni, C. coli, and C. fetus, but not by multiplex PCR that can specifically detect the cdtA, cdtB, and cdtC genes of the three bacterial species. The bacterial strain was identified as C. hyointestinalis by 16S rRNA gene analysis. Furthermore, the entire nucleotide sequence of the cdt genes was determined by genome walking upstream and downstream of the cdtB gene.
