Protein suspension from brewer's grains, method and apparatus for obtaining same
The group of inventions relates to the food industry, and more particularly to a method and device for transforming brewer's spent grain (BSG). The invention makes it possible to increase the level of recovery of edible fractions from BSG to 90-95%, and to increase the amount of protein in an edible suspension to not less than 50 wt % dry solids. The underlying principle of the invention is a technique for preparing BSG for nutrient extraction and extracting said nutrients by mechanical processing on a proposed industrial processing line. The essence of the claimed method lies in loosening BSG on a vibratory sieve, grinding the BSG in a colloid mill with the addition of water or centrate in a ratio of from 0.5:1 to 1:1 relative to BSG to produce a paste-like homogeneous mass of BSG, and then processing said mass in a screw extractor for further grinding and separation into two fractions: an edible suspension having a 90-95% moisture content and containing all of the nutrients of BSG, including protein substances; and ground BSG husks having a 60-75% moisture content, suitable for subsequent industrial use. The edible suspension is then mechanically filtered to remove ground husk residue, and the suspension is pumped into a storage tank.

STARCH-BASED DOUBLE-LOADED FUNCTIONAL NANO PARTICLE AS WELL AS PREPARATION METHOD AND APPLICATION
The preparation method of a starch-based double-loaded functional nanoparticle includes: performing restrictive hydrolysis treatment on egg high-density lipoprotein using proteases to obtain the polypeptide; performing self-assembling on a mixed system containing the polypeptide and quercetin under the alkaline condition to form a micelle nanoparticle; performing covalent grafting reaction on a mixed system containing the micelle nanoparticle and anthocyanin under the alkaline condition to form a graft; and electrostatically compounding carboxymethyl dextrin with the graft to obtain the starch-based double-loaded functional nanoparticle. In the preparation method, raw materials derived from natural sources are used, and the self-assembled colloid nanoparticle with good properties can be obtained by adjusting the pH without any organic reagents. The obtained product has a nanoparticle size, has high antioxidant activity and stability against environmental stress, and can be widely applied to the fields of delivery of nutrients, stabilization of biologically active substances and the like.

Anti-CD28 compositions
Provided herein are novel anti-CD28×anti-B7H3 (also referred to as “αCD28×αB7H3”) heterodimeric bispecific antibodies and methods of using such antibodies for the treatment of cancers. Subject αCD28×αB7H3 antibodies are capable of agonistically binding to CD28 costimulatory molecules on T cells and targeting to B7H3 on tumor cells. Thus, such antibodies selectively enhance anti-tumor activity at tumor sites while minimizing peripheral toxicity. The subject antibodies provided herein are particularly useful for enhancing anti-tumor activity when used in combination with other anti-cancer therapies.
CHITIN, HYDROLYSATE AND METHOD FOR THE PRODUCTION OF ONE OR MORE DESIRED PRODUCTS BY MEANS OF ENZYMATIC HYDROLYSIS, INCLUDING PRE-TREATMENT WITH AN OXIDISING AGENT
The invention relates to chitin, a hydrolysate and a method for the production of at least one desired product from insects. More specifically, the invention relates to a method for the production of chitin and/or chitosan from insect cuticles, comprising a step in which insect cuticles are treated with an oxidising agent, followed by a step involving the enzymatic hydrolysis of the insect cuticles using a proteolytic enzyme.
