An air bed with a stable supporting structure comprises a periphery sheet, a top sheet, and a bottom sheet. A middle sheet separates the air bed into an upper air-chamber and a lower air-chamber, an outer extending strip separates the upper air-chamber into a peripheral air-chamber and an upper main air-chamber, a first set of extending strips is provided in the upper main air-chamber, a second set of extending strips, which is welded to the middle sheet and the bottom sheet, is provided in the lower air-chamber, and an oblique extending strip is provided around the periphery of the second set of extending strips and is welded with the periphery sheet and the bottom sheet to separate the lower air-chamber into a lower main air-chamber and a peripheral auxiliary air-chamber. The lower main air-chamber is a space which has a shape of an inverse cone and receives air therein. Its outer surface is concave with respect to the outer surface of the peripheral auxiliary air-chamber, that is, the surface of the peripheral auxiliary air-chamber extends beyond the surface of the bottom sheet of the lower main air-chamber.

The object of the present invention is to overcome conventional demerits of pullulan powders prepared by conventional techniques, i.e., they could not be homogeneously mixed with non-reducing saccharides composed of glucose units when mixed together, and the resulting mixtures do not easily dissolve in water; and to provide a pullulan-containing powder with an improved rate of water dissolution, as well as to provide preparations and uses thereof. The present invention solves the above object by providing a pullulan-containing powder which uniformly comprises pullulan as a main ingredient and a non-reducing saccharide, and their process and uses; wherein the pullulan-containing powder is prepared by the steps of preparing a solution dissolving pullulan and a non-reducing saccharide homogeneously, pulverizing the solution, and collecting the resulting pullulan-containing powder. The powder has an improved rate of water dissolution, while retaining satisfactory resistance to humidity without fear of causing separation between the pullulan and the non-reducing saccharide.

Inflatable devices such as airbags are detailed. The bags may be formed of components well nested on linear rolls of material, reducing material wastage. The airbags additionally may, in some cases, be formed of components lacking curved surfaces; in certain cases the bag components additionally may have complementary surfaces that, although formed of straight segments, resemble convex and concave shapes.

To provide an epoxy resin composition that is suitable for producing optical sheets which exhibit excellent transparency, heat resistance, strength, smoothness and light resistance, and a cured product thereof.An epoxy resin composition for optical sheets, the composition comprising a polyvalent carboxylic acid (A) represented by formula (I):(wherein, R1's each independently represent a hydrogen atom, an alkyl group having 1 to 15 carbon atoms, or a carboxyl group; q represents the number of substituent R1's, and represents an integer from 1 to 4; and P represents any one of the following x, y and z):(wherein, there may be a plural number of R2's per ring, and R2's each independently represent a hydrogen atom or a methyl group; and * represents a bonding site linked to the oxygen atom;y. A linear alkylene linker having 6 to 20 carbon atoms, with a main chain having 3 or more carbon atoms and being substituted with an alkyl group in at least one site);(wherein, R's each independently represent a hydrogen atom, an alkyl group having 1 to 15 carbon atoms, or a carboxyl group; and * represents a bonding site linked to the oxygen atom, andan epoxy resin (B) having an aliphatic cyclic structure in the molecule).

The invention relates to a i-motif recombination mediated FRET probe and an application of the i-motif recombination mediated FRET probe in in-situ imaging of cancer cell surface protein homodimerization. In the strategy, an aptamer of a target protein, half (Half-i) of an i-motif forming sequence and an FRET donor-receptor pair are integrated into the probe. The probe is bound to a target proteinthrough aptamer binding. The protein subjected to homodimerization leads the two probes to be close to each other, so the two same Half-i sequences can be recombined into i-motif in an acidic tumor extracellular environment, and the FRET effect is further caused. The matching degree of the FRET generation mode and the protein homodimerization mode in the design is higher. The strategy realizes accurate and dynamic in-situ imaging of mesenchymal epithelial transformation (Met) receptor homodimerization on the surfaces of tumor living cells, and has huge potential in biomedical research.
