    Abstract: The present invention addresses the problem of providing an angiogenesis promoter capable of exerting an excellent angiogenesis promoting effect without containing any growth factor. The present invention also addresses the problem of providing a therapeutic method. An angiogenesis promoter that comprises as an active ingredient at least one member selected from the group consisting of a gelatin derivative represented by formula 1 and a crosslinked product of the gelatin derivative: In formula 1: Gltn represents a gelatin residue; L represents a single bond or a divalent linking group; and R1 and R2 independently represent a hydrocarbon group having 1-20 carbon atoms or a hydrogen atom, provided that at least one of R1 and R2 represents the aforesaid hydrocarbon group.

    Abstract: A method of the present invention is a method of inferring a content ratio of a component in a sample containing a component selected from K types, including: heating a sample set, ionizing resultant gas components sequentially, and observing mass spectra continuously; acquiring two-dimensional mass spectra of the respective samples from the mass spectra, and merging two or more of these spectra to acquire a data matrix; performing non-negative matrix factorization on the data matrix; correcting an intensity distribution matrix through analysis on canonical correlation between a base spectrum matrix and the data matrix; acquiring a feature vector from a corrected intensity distribution matrix and expressing the sample in vector space; defining a K-1 dimensional simplex and determining an end member; and inferring a content ratio of the component in the sample on the basis of the end member and the feature vector. It is possible to infer the composition of a component in an unknown mixture even from a mass spectrum acquired under an ambient condition.

    Abstract: The present invention suppresses an adverse effect caused when an additional gas such as water vapor is mixed in a sample gas or the like that is subjected to gas measurement. In an embodiment of the present invention, in gas measurement for analyzing sensor output signals obtained by alternately supplying a sample gas and a reference gas to a sensor element while alternately switching between the sample gas and the reference gas, the sample gas and the reference gas pass through a humidity equilibration device partitioned by a water vapor permeable membrane, and then are supplied to the sensor element. As a result, since both gases have substantially the same value of humidity at the time of being supplied to the sensor element, influences of water vapor are substantially cancelled out in signals output from the sensor element by the alternate supply of the sample gas and the reference gas.
