摘要:
A cell culture vessel supplies cells close to the center of gel and deeper down to the bottom with sufficient nutrients for attaining an enhanced survival rate of the cultivated cells. The cell culturing vessel comprises a culture tray capable of holding a liquid culture medium and a cell mixture container fixed to inner walls of the culture tray for retaining the cell mixture. Once the culture tray is filled with the liquid culture medium, the cell mixture retained in the cell mixture container has its opposite outer parts exposed to the liquid culture medium.

A resonator is connected to a first plane which is one of a power plane and a ground plane, wherein the power plane and the ground plane are apart from each other in an up-down direction. The resonator comprises a connecting portion and a body portion. The connecting portion is connected to the first plane. The connecting portion extends in the up-down direction beyond a second plane, which is a remaining one of the power plane and the ground plane, while not being in electrical contact with the second plane. The body portion is connected to the connecting portion while not being in contact with the second plane. The body portion is arranged so that the second plane is located between the body portion and the first plane in the up-down direction.

Provided is an ion sensor with which the concentration of ions in a solution can be determined without any reference electrode. The ion sensor is equipped with: a first electrode plate; a second electrode plate which has been disposed opposite the first electrode plate and has one or multiple openings; an ion-sensitive film continuously formed so that the film is interposed between the first electrode plate and the second electrode plate, blocks up one side of each opening of the second electrode plate, and extends from the end of that side of the opening to the outer surface of the second electrode plate through the inner wall surface of the opening; and a sensor support which supports the second electrode plate so that when the ion concentration of a test solution to be examined is determined, the ion-sensitive film comes into contact with the test solution only in the portions thereof that have been formed in each opening and on the outer surface of the second electrode plate. The ion sensor is configured so that the thickness of the ion-sensitive film interposed between the first electrode plate and the second electrode plate is different from the thickness of the ion-sensitive film formed on the outer surface of the second electrode plate. A difference in potential between the first electrode plate and the second electrode plate is measured.

摘要:
A method of conducting an endoscopic observation of an inner wall of a gastrointestine by applying a diagnostic agent to the inner wall of the gastrointestine, the diagnostic agent being an acidic aqueous solution of pH 1 to 5 containing a colorant, and conducting the endoscopic observation of the inner wall. The acidic aqueous solution can contain at least one acid selected from a carboxylic acid, hydrochloric acid, sulfuric acid and phosphoric acid. By applying the diagnostic agent to the inner wall of the gastrointestine in the endoscopic observation, it is possible to clearly observe a lesion which is difficult to be determined. In particular, the method can be used for observing lesions having cancer cells in the stomach or the Barrett's esophagus.

摘要:
Provided is a promoter showing transcriptional activity in a mesothelioma-specific manner and showing low transcriptional activity in other kinds of cancer cells and normal cells including mesothelium. Also provided are applications of the promoter, and more specifically, a gene therapy vector and a therapeutic agent for mesothelioma each including the promoter. The promoter includes a CRI1 gene-derived promoter, which is one kind of mesothelioma markers. The use of a vector including a cell death-inducing gene or a cell lysis-inducing gene as a transgene and carrying the CRI1 gene-derived promoter upstream of the transgene can induce a cell death or cell lysis action in a mesothelioma-specific manner. That is, the gene therapy vector and the therapeutic agent for mesothelioma each include a virus vector carrying the CRI1 gene-derived promoter.
