A foam separation method for harvesting Cr 3+ This method, belonging to the field of heavy metal wastewater treatment, uses the natural nonionic surfactant Sapindus mukorossi extract as a foaming agent and a trapping agent to treat Cr-containing wastewater. 3+ Cr in aqueous solution 3+ Foam separation and harvesting were performed. The critical micelle concentrations of Sapindus mukorossi extract and five other surfactants were determined, and the effects of pH, gas flow rate, liquid loading, collection time, Sapindus mukorossi extract concentration, and Cr were investigated. 3+ The effect of initial concentration on separation efficiency was investigated, and the process was optimized through orthogonal experiments. The results showed that at room temperature, with pH 6.5, gas flow rate 400 mL / min, collection time 4 min, loading volume 300 mL, Sapindus mukorossi extract 0.2 g / L, and chromium sulfate 10 mg / L, Cr... 3+ The recovery rate can reach 71.5%, and the enrichment ratio is 3.9. The foaming agent used in this invention is widely available, easily degradable, and environmentally friendly, and is suitable for low concentrations of Cr. 3+ Separate harvesting.

The invention provides two new applications of dehydroepiandrosterone sulfate (DHEA-S) in the field of alcohol related liver disease (ALD), and belongs to the field of biological medicine. First, the invention proposes that DHEA-S is used as a biomarker for auxiliary diagnosis and / or stage evaluation of ALD for the first time. Clinical research finds that the level of DHEA-S in human serum is in significant negative correlation with the severity of ALD, and can effectively assist in distinguishing different stages of diseases. Secondly, the invention discloses an application of DHEA-S in preparation of a medicine for preventing and / or treating ALD (Atomic Lymphosis Disease). Researches show that DHEA-S can significantly save ethanol-induced liver cell activity decline and significantly reduce liver pathological indexes of mice with alcohol-related liver injury. Therefore, the invention reveals that the DHEA-S has double values of serving as an excellent biomarker and an effective prevention and treatment component, and a brand new strategy is provided for accurate diagnosis and prevention and treatment of ALD.

This invention belongs to the field of food and feed technology, specifically relating to the application of bovine milk exosomes in the preparation of foods or feeds that promote animal feed intake and fat deposition. The feeding dosage of the bovine milk exosomes in the preparation of foods or feeds that promote animal feed intake and fat deposition is 1-10 mg. This invention effectively overcomes the defects and shortcomings of additives and appetite stimulants in the prior art, providing a new use for bovine milk exosomes. By regulating intestinal hormones and the activity of central feeding-related neurons, it effectively promotes animal feed intake and fat deposition.

This invention belongs to the field of biomedicine and reproductive health technology, specifically relating to the application of wheat germ extract in the preparation of products that improve the quality of aging oocytes. Through in vitro culture and in vivo gavage models, this invention demonstrates for the first time that wheat germ extract can significantly improve the in vitro maturation rate and in vivo superovulation maturation rate of oocytes from aged mice, significantly reduce intracellular reactive oxygen species levels, inhibit early apoptosis, and reduce oocyte mortality. The optimal in vitro concentration of the wheat germ extract is 0.1%–0.2%, and the optimal gavage dose is 5%. At these concentrations, the improving effect of wheat germ extract is significantly superior to that of spermidine. This invention provides a safe, natural, and long-term-accessible reproductive aging intervention strategy with good scientific value and promising prospects for industrial application.

The invention discloses an aquatic feed additive and feed for relieving heat stress of aquatic animals and a preparation method thereof, and the aquatic feed additive comprises the following components in parts by weight: 3-10 parts of a yeast culture, 0.5-2 parts of a dandelion extract, 0.5-2 parts of a citrus peel extract, 1-3 parts of beer yeast hydrolysate and 1-3 parts of a grape seed extract. Through optimal combination and synergistic effect of the yeast culture and various plant extracts, the comprehensive capability of the aquatic animals for resisting heat stress is improved in a multi-way and multi-level manner, adverse effects such as survival rate reduction caused by heat stress are effectively relieved, and the production performance of the aquatic animals is remarkably improved.
