摘要： Methods for removing endotoxin from naturally occurring materials, such as polysaccharides (e.g., agarose and/or carrageenan) are described herein. Polysaccharides that are substantially free of endotoxins and uses thereof are also described. The polysaccharide materials can be isolated from microorganisms, multicellular organisms, such as, algae, plants, seaweed, etc. The method involves the use of acidic and basic solutions to hydrolyze the lipid-polysaccharide bond in endotoxins. Cleaving the fatty acid from the polysaccharide reduces the water-solubility of the fatty acid and enables its removal with an organic solvent such as ethanol. The polysaccharide component can also undergo acidic or basic hydrolysis due to the weak glycosidic bond between the sugar rings.
摘要翻译：本文描述了从天然存在的材料如多糖（例如琼脂糖和/或角叉菜胶）中除去内毒素的方法。还描述了基本上不含内毒素的多糖及其用途。多糖物质可以从微生物，多细胞生物体，如藻类，植物，海藻等中分离。该方法包括使用酸性和碱性溶液来水解内毒素中的脂多糖键。从多糖中切下脂肪酸降低了脂肪酸的水溶性，使其能够用有机溶剂如乙醇除去。由于糖环之间的弱糖基键，多糖组分也可以进行酸性或碱性水解。

摘要： In one embodiment, the present invention is a substrate system of photo-polymerizable monomers and bioactive molecules admixed with the monomers and shielded from the monomers by an insoluble material that undergoes a solid-gel transition at body temperature. Upon polymerization, the monomers produce a cross-linked structure and the shielded bioactive molecules are protected from attack in the polymerized environment. In different aspects, the substrate system is used for drug delivery and tissue engineering and protection of enzymes, proteins and growth factors. In another embodiment, the present invention is a drug delivery system of photo-polymerizable monomers, drug molecules associated with the monomers and shielded from the monomers by an insoluble material that undergoes a solid-gel transition at body temperature, and a photopolymerizing means for polymerizing the monomers to produce a cross-linked structure including the drug molecules.

摘要： The present disclosure generally relates to beverages, and to systems and methods for creating beverages. In certain aspects, a beverage precursor can be contained within a gel, such as a carboxylate agarose gel or other gel suitable for human consumption. The precursor can be mixed with water to form a beverage. In some cases, a composition comprising the beverage precursor may also contain ice, e.g., a gel may be frozen or embedded in the ice. The ice may be heated or mixed with water (or otherwise physically disrupted) to release the precursor, which mixes with the water to form the beverage. A variety of beverage precursors are possible, including alcoholic beverages (e.g., beer, wine, rum, cognac, cocktails, etc.), juices, etc. In addition, in certain embodiments, the precursors may also include gas-forming agents, and/or other ingredients suitable for drinks, such as sugar, artificial sweetener, food coloring, flavoring, etc. Other aspects include methods for making or using such compositions, kits including such compositions, or the like.
