The application relates to a microbial preparation passing through the rumen, a preparation method and application thereof. The microbial preparation passing through the rumen comprises microbial powder and a coating material coated on the surface of the microbial powder. The coating material comprises protective fat. The total weight of fatty acids in the microbial preparation passing through the rumen is 100%, the fatty acids comprise 70wt%-80wt% of palmitic acid and stearic acid, <=9wt% of oleic acid, 5wt%-15wt% of polyunsaturated fatty acids and a residual amount of non-target fatty acids, the mass ratio of the palmitic acid to the stearic acid is 1:1-2:1, the polyunsaturated fatty acids are selected from at least one of docosahexaenoic acid, eicosatetraenoic acid and eicosapentaenoic acid, and the mass ratio of the microbial powder to the protective fat is 2:3-3:2. The microbial preparation passing through the rumen described in the application is used as a feed additive for feeding ruminants such as cows, and can realize the dual improvement of the production performance of the cows and the nutrition strengthening of the milk.

The invention discloses application of a marker metabolite in identification of different harvest periods of porphyra haitanensis, and belongs to the field of food analysis and detection. The marker metabolites comprise lysophosphatidylethanolamine 15: 1 *, 2 '-deoxyguanosine, L-gamma-glutamine-L-leucine, lysophosphatidylethanolamine 22: 5, lysophosphatidylethanolamine 17: 1 *, 3, 4-dihydroxyphenylacetic acid *, 12S-hydroxy-5Z, 8Z, 10E, 14Z-eicosatetraenoic acid, lysophosphatidylcholine 18: 0 (2n isomerization) and 1-(2, 4-dihydroxyphenyl)-1-(2, 4-dihydroxyphenyl)-1-(2, 4-dihydroxyphenyl)-1-(2, 4-dihydroxyphenyl)-1-(2, 4-dihydroxyphenyl)-1-(2, 4-dihydroxyphenyl)-1-(2, 4- )-3-(((2-(dimethylamino) ethyoxyl) (hydroxy) phosphoryl) oxy) propan-2-yl palmitate *, and the like. The screening method of the marker metabolite reveals the difference of the porphyra haitanensis in different harvesting periods, the technology is advanced, the experimental result is reliable, and an excellent method is provided for quality identification and quality evaluation of the porphyra haitanensis.

This disclosure provides novel heterocyclic compounds and methods for inhibiting the enzyme CYP4. Further disclosed methods include: a method of inhibiting the biosynthesis of 20-hydroxyeicosatetraenoic acid (20-HETE) in a subject in need thereof and a method of producing neuroprotection and decreased brain damage by preventing cerebral microvascular blood flow impairment and anti-oxidant mechanisms in a subject experiencing or having experienced an ischemic event.

The invention relates to the technical field of compositions, and particularly discloses an application of a special medical-purpose formula food composition suitable for infants allergic to food protein to the non-treatment purpose of improving eosinophilic esophagitis. The special medical use formula food composition suitable for infants allergic to food proteins comprises docosahexaenoic acid, eicosatetraenoic acid and nucleotides. The special medical formula food composition suitable for infants allergic to food protein provided by the invention can improve esophageal epithelial hyperplasia and reduce the level of IL-13 cell factors by increasing the number of bifidobacteria and reducing the number of enterobacter and eosinophilic granulocytes in esophageal tissue, so that the eosinophilic granulocytic esophagitis is remarkably improved.

The application relates to the technical field of judging or confirming hypophthalmichthys nobilis, and particularly relates to a fatty acid biomarker for distinguishing wild and cultured hypophthalmichthys nobilis, a method and an application. The biomarker comprises at least one of tetradecanoic acid, cis, cis, cis-9, 12, 15-octadecatrienoic acid, cis-5, 8, 11, 14-eicosatetraenoic acid and cis-5, 8, 11, 14, 17-eicosapentaenoic acid. The biomarker can accurately distinguish wild and cultured hypophthalmichthys nobilis, provide scientific basis and technical support for relevant law enforcement departments, strengthen supervision and strike force of illegal fishing behavior in the Yangtze River basin, reduce overfishing of wild resources, and further provide a technical basis for better management and protection of hypophthalmichthys nobilis resources.
