Described herein are devices and methods for increasing the production of steviol glycosides, which have industrial and economic value. The steviol glycosides produced by the devices and methods disclosed herein do not require the ultra purification that is common in conventional or commercial methods and do not have a bitter aftertaste, making them better suited as flavor-enhancing additives to food, pharmaceutical, and nutritional supplement products.

Provided is a method for preparing a diabetic dog model by means of gene editing technology, a diabetic dog model prepared therefrom, as well as cells and issues thereof. The method comprises the following steps: (1) obtaining a dog fertilized egg cell, which comprises a point mutation in GCK gene, for a diabetic dog model by means of gene editing; and (2) transplanting the dog fertilized egg cell into one fallopian tube of a female dog, in which both fallopian tubes have been flushed, to prepare a diabetic dog model comprising a point mutation in GCK gene.

The present disclosure relates to an epimerase protein of fructose-6-phosphate, nucleic acid molecule encoding the epimerase protein, a recombinant vector and a transgenic microorganism which comprise the nucleic acid molecule, and a composition for producing allulose by using them.

The present invention discloses anti-cancer compositions, and associated methods, including an anti-cancer composition comprising: a cellular energy inhibitor having the structure according to formula I ##STR00001## wherein X is selected from the group consisting of: a nitro, an imidazole, a halide, sulfonate, a carboxylate, an alkoxide, and amine oxide; and R is selected from the group consisting of: OR′, N(R″).sub.2, C(O)R′″, C1-C6 alkyl, C6-C12 aryl, C1-C6 heteroalkyl, a C6-C12 heteroaryl, H, and an alkali metal; where R′ represents H, alkali metal, C1-C6 alkyl, C6-C12 aryl or C(O)R′″, R″ represents H, C1-C6 alkyl, or C6-C12 aryl, and R′″ represents H, C1-C20 alkyl or C6-C12 aryl. The anti-cancer composition can additionally comprise at least one sugar, which stabilizes the cellular energy inhibitor by substantially preventing the inhibitor from hydrolyzing. Also, the anti-cancer composition can comprise a hexokinase inhibitor. Further, the anti-cancer composition can comprise a biological buffer that is present in an amount sufficient to at least partially deacidify the cellular energy inhibitor and neutralize metabolic by-products of the cellular energy inhibitor.

The present invention provides a measuring method for at least one of a kinase forward reaction substrate, a phosphorylated product thereof, and a precursor thereof, and includes a step of conducting an enzymatic cycling reaction by bringing at least a kinase, a first nucleotide coenzyme of the kinase, and a second nucleotide coenzyme having a different nucleoside moiety from the first nucleotide coenzyme into contact with a sample; a step of detecting a signal corresponding to a change of at least one of the first nucleotide coenzyme and a conversion product thereof, and the second nucleotide coenzyme and a conversion product thereof; and (3) a step of calculating, on the basis of the detected change of the signal, an amount of the kinase forward reaction substrate and/or the phosphorylated product thereof contained in the sample.

Disclosed herein are methods, compositions, apparatus, systems and kits for performing polynucleotide amplification utilizing a pure polynucleotide polymerase. In some cases, disclosed herein are methods, compositions, apparatus, systems and kits for sequencing polynucleotides.

This disclosure provides a composition containing a conjugate with a modified insulin molecule. The conjugate has an insulin molecule, which can be insulin or an insulin analog, glucagon, GLP-1, GLP-2 or a GLP-1 agonist. The conjugate also contains one or more polymers. Each of the one or more polymers is covalently linked to the insulin molecule. Additionally, each of the one or more polymers is covalently linked to between 0 to 50 copies of a decoy ligand, and to between 0 to 50 copies of a glucose-binding agent, such that the combined total number of glucose-binding agents and decoy ligands covalently linked to each of the one or more polymers is at least 1. The conjugate can reversibly bind to soluble glucose and in which the extent of its glucose-binding controls the extent to which the modified insulin is able to bind to and activate the insulin receptor. Methods of making the conjugate, as well as use of the conjugate in treatment, are also provided.
