Silver nanowires coated with, instead of a polymer protective agent such as PVP, an organic protective agent having a smaller molecular weight are provided. The silver nanowires have an average diameter of 100 nm or less and an average length of 5 m or more, and a thiol having a molecular weight of 75 to 300 is adhered on surfaces of the metal silver. The silver nanowires have a thiol containing one thiol group in the structure adhered thereon. A thiol having only one thiol group (SH) in a molecule is a suitable target. Examples thereof include 1-dodecanethiol, 1-decanethiol, 1-octanethiol, 3-mercapto-1,2-propanediol, monoethanolamine thioglycolate, ammonium thioglycolate, and thiomalic acid.

The present invention provides a system for analyzing an expression profile in which a large number of expression profile data obtained by a next-generation high-speed sequencer, a similar experimental technique, or the like is analyzed at high speed by a general-purpose computer, gene expression patterns are visualized, thereby easily analyzing to which gene a novel gene is similar in function. A system for analyzing an expression profile which analyzes gene expression profile data includes a storage unit which stores the number of counts of mRNAs expressed from a subject gene to be evaluated as expression data under each of a plurality of gene expression conditions for each subject gene name, a correspondence analysis unit which reads the expression data from the storage unit for each subject gene, and carries out correspondence analysis on the basis of the number of counts under each expression condition in expression data, a coordinate conversion unit which converts n-dimensional (n: natural number) scores obtained by the correspondence analysis to coordinate values for m-dimensionally (m: natural number, mn) arranging each subject gene, and an image processing unit which carries out plotting along the corresponding coordinate values for each gene to display the result on an image display unit.

Boron nitride (BN) nanomaterials were synthesized from LaB6 and Pd/boron powder, and the hydrogen storage was investigated by differential thermogravimetric analysis, which showed possibility of hydrogen storage of 1-3 wt%. The hydrogen gas storage in BN and carbon (C) clusters was also investigated by molecular orbital calculations, which indicated possible hydrogen storage of 6.5 and 4.9 wt%, respectively. Chemisorption calculation was also carried out for B24N24 cluster with changing endohedral elements in BN cluster to compare the bonding energy at nitrogen and boron, which showed that Li is a suitable element for hydrogenation to the BN cluster. The BN cluster materials would store H2 molecule easier than carbon fullerene materials, and its stability for high temperature would be good. Molecular dynamics calculations showed that a H2 molecule remains stable in a C60 cage at 298 K and 0.1 MPa, and that pressures over 5 MPa are needed to store H2 molecules in the C60 cage. © 2014 by the authors.

Retinal image examination is useful for early detection of glaucoma, which is a leading cause of permanent blindness. In order to evaluate the presence of glaucoma, ophthalmologists may determine the cup and disc areas and diagnose glaucoma using a vertical cup-to-disc ratio. However, determination of the cup area based on computation algorithm is very difficult, thus we propose a method to measure the cup-to-disc ratio using a vertical profile on the optic disc. The edge of optic disc was then detected by use of a Canny edge detection filter. The profile was then obtained around the center of the optic disc. Subsequently, the edges of the cup area were determined by classification of the profiles based on zero-crossing method. Lastly, the vertical cup-to-disc ratio was calculated. Using forty five images, including twenty three glaucoma images, the AUC of 0.947 was achieved with this method.

A production method of silver nanowires exhibits a yield enhancement effect for a protective agent other than PVP. The method for producing silver nanowires includes depositing a silver linear structure, which is referred to as silver nanowires, in an alcohol solvent having a silver compound, a halogen compound, and an organic protective agent dissolved therein. A deposition reaction of silver is performed in a state where aluminum nitrate is further dissolved in the solvent, the total amount of aluminum nitrate dissolved in the solvent being from 0.01 to 0.50 in terms of Al/Ag molar ratio with respect to the total amount of the silver compound. The organic protective agent is, for example, one containing one or more kinds of alkylated PVP and a PVP-PVA graft copolymer.

Magnetic fluid hyperthermia is a cancer treatment technique that utilizes the heat dissipated by magnetic nanoparticles exposed to an alternating current magnetic field. The heat dissipated is consequence of the conversion of the magnetic energy through different relaxation mechanisms, which depends on the physical properties of the magnetic particles. Particularly, in the case of magnetic nanoparticles, the magnetic energy is converted to heat energy either by the resistive response of the rotation of the magnetic particles (Brownian relaxation) or the rotation of the magnetic moment within the particles (Néel relaxation) to the alternating magnetic field. In this article, the main focus has been on the progress of theoretical and experimental investigations towards the realization of magnetic fluid hyperthermia (MFH) through heat dissipation by Néel relaxation of magnetite particles. We discuss about the present status and prospects of magnetite nanoparticles-based hyperthermia focusing mainly on the dissipation of heat through Néel relaxation mechanism. In doing so, an attempt has been made to review and deepen the understanding on specific topics such as (a) specific heat absorption characteristics of magnetite, especially the physical properties of particles that generate heat through Néel relaxation, (b) the preparation techniques available to synthesize particles with required properties, (c) experimental investigations carried out to determine the relative contribution of Néel relaxation to dissipate heat and their potential for in vivo application, and (d) the theoretical estimation of and experimental verification of heat diffusion characteristics of magnetite. The theoretical and experimental studies have suggested that the development of case specific treatment technologies based on an integrated approach considering both the physical constraints of the magnetic particles to be used as thermal seeds and practically feasible alternating magnetic field generators is a must for the establishment of MFH therapy in the foreseeable future. © 2010 The Ceramic Society of Japan.

High-resolution electron microscopy and electron diffraction are quite useful for structural characterization of perovskite-type superconducting copper oxides on the atomic scale. Valuable information on the crystal structures and the microstructures could be obtained from observed high-resolution images if severe conditions such as thinner crystals and definite defocus values are satisfied. The structure images and electron diffraction patterns include information not only on accurate atomic coordinates of cations but also on ordered arrangements of oxygen atoms and oxygen vacancies. Crystal structures of the various perovskite-type copper oxides were analyzed from the observed structure images. Modulated structures, defects, intergowth, surfaces, and interfaces were also investigated.
