Patent
Clio Inc. and Tohoku University | Date: 2017-01-23

An object of the present invention is to provide a novel medical application to regenerative medicine that uses pluripotent stem cells (Muse cells). The present invention provides a cell preparation for treating cerebral infarction and sequelae associated therewith that contains SSEA-3-positive pluripotent stem cells isolated from mesenchymal tissue in the body or cultured mesenchymal cells. The cell preparation of the present invention is based on a brain tissue regeneration mechanism by which Muse cells differentiate into nerve cells and the like in damaged brain tissue by administering Muse cells into cerebral parenchyma.

An object of the present invention is to provide a novel medical application to regenerative medicine that uses pluripotent stem cells (Muse cells). The present invention provides a cell preparation for treating chronic kidney disease that contains SSEA-3-positive pluripotent stem cells isolated from mesenchymal tissue in the body or cultured mesenchymal cells. The cell preparation of the present invention is based on a renal tissue regeneration mechanism by which Muse cells are made to selectively accumulate at a site of kidney disease and differentiate into cells that compose the kidney by administering Muse cells intravenously to a subject having the aforementioned disease.

Alloy powder of a composition formula Fe_(100-a-b-c-d-e-f)Co_(a)B_(b)Si_(c)P_(d)Cu_(e)C_(f) having an amorphous phase as a main phase is provided. Parameters satisfy the following conditions: 3.5 a 4.5 at%, 6 b 15 at%, 2 c 11 at%, 3 d 5 at%, 0.5 e 1.1 at%, and 0 f 2 at%. With this composition, the alloy powder has good magnetic characteristics even when it has a large particle diameter such as 90 m. Therefore, yield thereof is improved.


Provided is a photodiode having a high-concentration layer on its surface, in which the high-concentration layer is formed so that the thickness of a non-depleted region is larger than the roughness of an interface between silicon and an insulation film layer, and is smaller than a penetration depth of ultraviolet light.

Provided is a corrosion-resistant, high-hardness alloy composition, which realizes both corrosion resistance and high hardness by using a Ni-Co-Cr-Mo-based alloy and optimizing the chemical composition, heat treatment conditions and processing conditions thereof, and a method for producing that alloy composition. The alloy composition is an alloy composition comprising 15.5% by weight to 16.5% by weight of Cr, 7.5% by weight to 15.5% by weight of Mo, 0% by weight to 30% by weight of Co, 4.5% by weight to 15% by weight of Fe and 0.5% by weight to 4.0% by weight of Cu, with the remainder consisting of Ni and unavoidably included elements, wherein the crystal phase consists only of a phase and the Vickers hardness at room temperature is 500 HV or more. The alloy composition is obtained by subjecting an ingot of an alloy having the aforementioned composition to homogenization treatment for 4 hours to 24 hours at 1100C to 1300C, followed by subjecting to cold processing at a compression rate of 30% to 60% and then to aging treatment for 0.5 hours to 3 hours over a temperature range of 300C to 600C.

The present invention provides an electrically conductive material including a base and a conductive polymer applied uniformly to the bases surface and having a reduced resistance value. Specifically, the electrically conductive material includes PEDOT-pTS, serving as a conductive polymer, applied to the base comprised mostly of silk. The invention also provides a method for producing the electrically conductive material, and a bioelectrode including it. The method includes the steps of: (1) applying a p-toluenesulfonate (pTS) solution containing an oxidant component and pTS to a base selected from the group consisting of a silk fiber, a fiber containing sericin or fibroin, and a fiber coated or soaked with sericin or fibroin; and (2) further applying 3,4-ethylenedioxythiophene (EDOT) to the base that already has the oxidant component and pTS applied thereto through the step (1), thereby triggering, at the base, a polymerization reaction to form poly(3,4-ethylene-dioxythiophene)-p-toluenesulfonate (PEDOT-pTS) and applying the formed PEDOT-pTS to the base.


A heat treatment apparatus for a laminated body of amorphous alloy ribbon includes: a lamination jig that holds the laminated body of amorphous alloy ribbon; two heating plates that sandwich the laminated body from upper and lower surfaces in a lamination direction without coming into contact with the lamination jig; and a heating control apparatus that controls a heating temperature of the two heating plates.
