  • Patent number: 10221204
    Abstract: A composition which has high 4?-GL purity and can be used as a reference standard for various analyses can be obtained by a more convenient method than one conventionally used. A method for preparing a high-purity 4?-GL composition includes the steps of: (A) subjecting a 4?-GL-containing galacto-oligosaccharide to activated carbon column chromatography, and performing stepwise elution with plural organic solvent aqueous solutions, wherein the organic solvent aqueous solutions are used such that the concentration of the organic solvent in the organic solvent aqueous solution is higher than the concentration of the organic solvent in the immediately preceding organic solvent aqueous solution with respect to a series of elutions; and (B) adding an organic solvent to the final fraction eluted in step (A), and crystallizing the 4?-GL.

  • Patent number: 9988641
    Abstract: This invention disclosure relates to novel maize starch. The starch can be made from the newly developed waxy sugary-2 double-mutant maize that has low activity of Granule Bound Starch Synthase I (GBSSI), which results in low amylose level. The starch from newly developed waxy sugary-2 double-mutant is freeze-thaw stable and has high viscosity. In comparison with the starch of the existing waxy sugary-2 double-mutant maize, the new waxy sugary-2 double-mutant maize starch showed, inter alia, improved pasting profile, starch granule integrity, larger starch granule size, and higher viscosity.

  • Patent number: 9877986
    Abstract: An apparatus for portable delivery of nitric oxide without the need for pressurized tanks, power supplies, or other devices provides a single therapy session by triggering a heater to heat a reaction chamber. A piercing assembly may trigger to open sealed containers, such as bags, of liquid water or salt water in order to activate the heaters. Upon addition of liquid such as water or salt water to a chemically reactive heating element, heat is generated to activate the chemicals generating nitric oxide within a sealed reactor. Upon triggering, liquid containers are unsealed, the liquid drains down to initiate reaction of the heating chemicals, and the heat begins to penetrate the reactor. The reactor, in turn, heats its contents, which react to form nitric oxide expelled by the reactor to a line feeding a cannula for therapy.

  • Patent number: 9861956
    Abstract: Provided by the present invention is a photocatalytic coating composition which can express excellent visibility during application work and further can, owing to its excellent physical properties, form a homogeneous photocatalyst coated film having uniform thickness on a surface of a substrate. The photocatalytic coating composition which is basic and comprises photocatalyst particles, a basic dye, a layered silicate, and a dispersion medium. The basic dye enhances visibility of the part where the photocatalytic coating composition is applied so that the applied part can be easily distinguished from the unapplied part by the difference in appearance. After application work, color of the basic dye disappears by photolysis with a solar light or by decomposition with a photocatalyst. The layered silicate suppresses color change of the basic dye over time and stably keep color tone of the same.
