Abstract: The present invention provides a disease model animal for tauopathies which reproduces the expression pattern of tau protein isoforms of adult human brain, that is, approximately equal amounts of 3R type tau and 4R type tau being expressed in the adult brain. The method for producing the disease model animal for tauopathies of the present invention comprises the steps of: preparing a tau seeds; and injecting the tau seeds in the brain of an animal carrying a mutation in the tau gene which fails to express the tenth exon. The animal carrying a mutation in the tau gene which fails to express the tenth exon may be produced by using any of the genome editing, gene targeting or base editing technologies.

Abstract: A server is connected to an electronic device and systems of a plurality of cryptocurrency exchanges over a network. An information reception unit receives first board information and second board information from systems of first and second cryptocurrency exchanges that conduct buy-sell transactions of a cryptocurrency in first and second main currencies, respectively. A conversion unit converts second limits into third limits in a first main currency based on an exchange rate between the first and second main currencies. A totalization unit calculates a total order quantity obtained by totalizing buy-sell order quantities in the first board information and the second board information, for each of fourth limits into which first limits and the third limits are joined. Third board information that includes total order quantities corresponding to the fourth limits in the first board information and the second board information is displayed on the electronic device.
