Abstract: The invention discloses the use of the Schizochytrium limacinum and its preparation in improving the quality and yield of animal product. The deposit number of Schizochytrium limacinum in the present invention is CGMCC No. 13746 in the China General Microbiological Culture Collection Center. The Schizochytrium limacinum powder produced by the Schizochytrium limacinum may increase the DHA content in an animal product, reduce the cholesterol content in an animal product, and also improve the egg production performance of poultry. This animal product with high DHA content from natural sources is organic, safe, stable, and easy to be absorbed. It may be used as a safer and effective way for people to ingest natural DHA, and it may also cater to and meet consumer needs. Thus, Schizochytrium limacinum and Schizochytrium limacinum powder of the present application have a wide range of application in the field of general food and livestock breeding.
Abstract: Provided is a method of inducing oligodendrocyte precursor cells (OPCs) through direct reprogramming from human somatic cells into which a nucleic acid molecule encoding an Oct4 protein or Oct4 protein-treated human somatic cells. The method of inducing OPCs by treating Oct4-overexpressing human somatic cells with a low molecular weight substance may establish OPCs with high efficiency in a short period of time through direct reprogramming without via neural stem cells, and thus the OPCs are useful as a cell therapeutic agent for an intractable demyelinating disease.

Abstract: Provided are methods to destabilize emulsion feedstocks. In the methods, a moderate temperature is applied to the feedstock to create a first mixture. The moderate temperature may be between 120 and 220 degrees Celsius. The first mixture is mixed at the moderate temperature, such as by staged mixing in some embodiments. Moreover, the first mixture is retained at the moderate temperature for up to six hours. The first mixture is separated into an oil phase, convoluted phase, and a water phase. In some embodiments, the moderate temperature may be 125 to 150 degrees Celsius, such as between 125 and 130 degrees Celsius. Moreover, the first mixture may be retained at the moderate temperature for between forty-five minutes and four hours, such as from two to four hours. The separation may occur at the moderate temperature.

Abstract: A biological toxicity test method for evaluating an ecological safety of an advanced oxidation process comprising the following steps: (1) collecting (preparing) a waste water to be determined; (2) collecting the waste water and a tap water after the advanced oxidation process treatment; (3) subjecting Koi (Cyprinus carpio haematopterus) to the water after treatment for exposure to poison; (4) Determining an anti-oxidation enzyme activity of a liver of the Koi after exposure; (5) Data analyzing. By comparing the changes of liver enzyme activities in different water, the present method evaluates the toxicity changes of micro-pollutant containing water before and after treatment, which fills in the gap of the ecological risk assessment for advanced oxidation technology.
Abstract: A method for preparing placenta membrane tissue grafts for medical use, includes obtaining a placenta from a subject, cleaning the placenta, separating the chorion tissue from the amniotic membrane, mounting a selected layer of either the chorion tissue or the amniotic membrane onto a drying fixture, dehydrating the selected layer on the drying fixture, and cutting the selected layer into a plurality of tissue grafts. Preferably, the drying fixture includes grooves or raised edges that define the outer contours of each desired tissue graft, after they are cut, and further includes raised or indented logos that emboss the middle area of the tissue grafts during dehydration and that enables an end user to distinguish the top from the bottom side of the graft. The grafts are comprised of single layers of amnion or chorion, multiple layers of amnion or chorion, or multiple layers of a combination of amnion and chorion.
