摘要:
The present invention provides crosslinked carboxymethylcellulose having high elastic modulus coupled with high absorbance capacity when swollen in simulated gastric fluid/water (1:8) and simulated intestinal fluids. The invention further provides methods of making the crosslinked carboxymethylcellulose, compositions comprising the crosslinked carboxymethylcellulose and methods of using the crosslinked carboxymethylcellulose, for example, for treating overweight or obesity or for enhancing glycemic control.

摘要:
The present invention relates to methods of managing weight, and treating overweight or obesity and treating or preventing diabetes in a subject in need thereof. In one embodiment, the method comprises the steps of (a) orally administering to the subject from about 0.7 g to about 4 g of crosslinked carboxymethylcellulose; and (b) orally administering to the subject at least about 100 mL of water per gram of crosslinked carboxymethylcellulose. Steps (a) and (b) are conducted prior to or with at least one meal per day.
摘要:
The present invention provides a method of producing a polymer hydrogel comprising the steps of: (1) preparing an aqueous solution of a water soluble polysaccharide derivative and a polycarboxylic acid; (2) optionally agitating the solution, for example, by stirring; (3) isolating a polysaccharide derivative/polycarboxylic acid composite from the solution; and (4) heating the polysaccharide derivative/polycarboxylic acid composite at a temperature of at least about 80° C., thereby cross-linking the polysaccharide with the polycarboxylic acid. The invention also provides polymer hydrogels produced by the methods of the invention.
摘要:
The invention relates to a method for the preparation of a polymer hydrogel, comprising cross-linking a precursor comprising a hydrophilic polymer optionally in combination with a second hydrophilic polymer, using polycarboxylic acid as the cross-linking agent. The invention further concerns the polymer hydrogel obtainable by the method of the invention and the use thereof in a number of different applications.
