Abstract: Dermal filling materials and techniques are disclosed herein. In particular, dermal fillers containing low melt agarose (i.e., agarose having a melting temperature of less than 65° C.) are described. The disclosed dermal fillers can be manipulated after injection by, for example, heating and/or cooling the dermal filler while inside the patient to adjust its positioning or stiffness.
Abstract: The present invention is related to a compound conjugating a drug with a glycosaminoglycan, such as hyaluronic acid (HA), where the drug is useful for the treatment of diseases such as inflammation, auto-immune disease, allergy, infection and preferably cancer. The conjugated compound of the present invention can increase the concentration of drug at the specific site of disease by an interaction of the glycosaminoglycan used as target drug delivery carrier and the CD44 cell surface receptor, then enhancing the therapeutic efficacy and reducing the systemic side effect of the site-delivered drug.
Abstract: Poly alpha-1,3-glucan ester compounds are disclosed herein with a degree of substitution of about 0.001 to about 3.0. Also disclosed are methods of producing poly alpha-1,3-glucan ester compounds using cyclic organic anhydrides.

Abstract: The present invention relates to a compound of dihydrophaseic acid 3?-O-beta-D-glucopyranoside for the prevention and treatment of osteoporosis. It was found that the D3G isolated from the Lycium root bark extract induces the activity of osteoblast differentiation while promoting the proliferation of pre-osteoblast, and promotes the bone remodeling by promoting the differentiation of both osteoblast and osteoclast when mixing and culturing pre-osteoblast which is the precursor of osteoblast, and monocyte which is the precursor of osteoclast. Therefore, the D3G of the present invention is expected to be useful as a pharmacological agent or functional food effective for the prevention and treatment of osteoporosis which is a disease caused by the abnormal balance of bone remodeling.
