Adefovir dipivoxil added to ongoing lamivudine in chronic hepatitis B with YMDD mutant hepatitis B virus. Enhanced cleavage of type II collagen by collagenases in osteoarthritic articular cartilage. The principles of classification and a classification of mammals / GTPase inhibiting mutations activate the |[alpha]| chain of Gs and stimulate adenylyl cyclase in human pituitary tumours Increased damage to type II collagen in osteoarthritic articular cartilage detected by a new immunoassay. Damage to type II collagen in aging and osteoarthritis starts at the articular surface, originates around chondrocytes, and extends ...
