    摘要:A process is described which uses whole cell preparations, immobilized or without immobilization, of a microorganism, including Aureobasidium pullulans , capable of forming enzymes of the group of fructosyltransferases, for catalyzing a reaction between sucrose and 6-O-protected glucose for formation of 6-O-protected sucrose, an intermediate in synthesis of trichlorogalactosucrose. 6-O-protected Sucrose is separated from high molecular weight by-products of the reaction having molecular weight of 500 daltons and more by reverse osmosis, and further purified by column chromatography.

    摘要:The disclosure provides methods of synthesis of polymeric scaffolds, e.g., those useful for conjugating with a protein based recognition-molecule (PBRM) to form PBRM-polymer-drug conjugates, and PBRM-polymer-drug conjugates thereof. The methods according to the disclosure allow for large-scale preparation of polymeric scaffolds having a high purity. In some embodiments, the methods according to the disclosure also allow for the preparation of scaffolds and conjugates thereof in better yield than previously used methods for preparing same. Also disclosed are methods of purifying polymeric scaffolds.

    摘要:The present disclosure provides methods for enhancing muscle protein synthesis in an individual in need of same. Specifically, the present disclosure provides methods for enhancing muscle protein synthesis by enhancing myofibrillar muscle protein synthesis. The method includes administering to the individual a mixed macronutrient composition having (i) an amount of whey protein that is not capable of enhancing myofibrillar protein synthesis when ingested by itself and (ii) free leucine. The composition comprises at least about 5.0 g total leucine per dose.

    权利人:NESTEC SA
    摘要:The present disclosure provides methods for enhancing muscle protein synthesis following physical exertion. In a general embodiment, a method for enhancing muscle protein synthesis following physical exertion is provided and includes administering to an individual a composition comprising from about 15 to about 35 g protein immediately following concurrent training. Programs for enhancing muscle adaptation resulting from concurrent training are also provided. The programs include providing a composition comprising from about 15 to about 35 g protein; and providing guidelines for consumption including a recommendation of the amount of the composition to consume immediately following concurrent training.

    摘要:The present invention relates to plants with increased levels of water soluble carbohydrates, particularly fructan, in the stem and leaf sheath. The present invention also provides methods of identifying and/or producing these plants. In particular, the present invention relates to a novel class of polypeptides designated MYB13 which upregulate the expression of enzymes involved in fructan synthesis. The present invention further relates to a novel promoter element that can be used to express genes predominantly in the stem and leaf sheath during the early reproductive stage of a plant.
