Abstract: A treatment for pruritus is described that is based upon amylase. The amylases (?-, ?-, ?-amylase) are noted for the cleavage of the ?-glycosidic bonds of polysaccharides, yielding lower molecular weight carbohydrate/sugar fragments. It has now been found that ?-amylase is effective in the reduction of pruritus (itching) of affected tissue.

Abstract: Using a novel water-soluble, active ester amide-containing functionalized controlled radical polymerization initiator, stimuli responsive polymers have been grown from the surface of a protein, exemplified by chymotrypsin or any protein having surface amino acids that will covalently bind to the active ester amide-containing functionalized initiator. It is shown that changes in temperature or pH can change the conformation of the polymer surrounding the enzyme, which in turn enabled the rational tailoring of enzyme activity and stability. This method has afforded an increase in the activity and stability of the enzyme by an order of magnitude at pH's where the enzyme is usually inactive or unstable. Multimodal temperature responsive protein-block copolymer conjugates are described.

Abstract: Alzheimer's disease is treated by attacking hyperactive microglia preferably before excessive beta amyloid is built up by administering tin-117m-DOTA annexin V. This compound in low radioactive doses selectively binds to the aged hyperactive microglia and emits a conversion electron which effectively induces apoptosis in the hyperactive microglia. A follow-up treatment of tin-annexin A1 can be administered to repair the blood brain barrier. The annexin A1 assists in the repair of the blood-brain barrier and the associated tin-117m will induce apoptosis in aged hyperactive microglia associated with the blood brain barrier.
