Abstract: A polymeric material comprised of (i) at least one random copolymer comprised of ethylene oxide and one or more other alkylene oxide(s) and (ii) at least one non-random polymer comprised of one or more poly(alkylene oxide)s has been discovered. Preferably, it is a polymer alloy. Alkylene oxide homo-polymers or block copolymers may be the non-random polymer. In a related discovery, an adhesive material can be made by suspending (a) particles in (b) a matrix of at least one poly(ethylene oxide) copolymer of ethylene oxide and propylene oxide, or a combination thereof. The handling characteristics may be adjusted for different utilities (e.g., from runny oil to hard wax). Applications include use as adhesive, cohesive, filler, lubricant, surfactant, or any combination thereof. In particular, the hard materials may be used for cleaning or waxing.

Abstract: A method for controlling bleeding from bones, comprising the use of copolymers of oxyethylene and oxypropylene or mixtures thereof to cover the bleeding portions of bones. The copolymers are resorbable by the body, not metabolized, simple to prepare, inexpensive, readily available, and do not interfere with the fusion, osteogenesis, and related tissue healing and repair of the affected bones.

Abstract: We describe the medical, dental, and surgical uses of modified poly(alkylene) materials which are fully resorbable after implantation into the body, and compositions formulated with such modified poly(alkylene) materials.

Abstract: The present invention discloses methods and devices for selectively removing anti-PEG antibodies from a patient's blood prior to administration of a PEG-conjugated therapeutic agent so as to prevent immune reactions against the PEG-conjugated therapeutic agents when the agents are administered as a therapeutic regimen. Removal of anti-PEG antibodies may be physical, in which anti-PEG antibodies are physically removed from the blood through an extracorporeal blood circuit connected to an anti-PEG antibody removal device, or functional, in which an anti-PEG inactivating agent is infused into the patient's blood stream prior to administration of the PEG-conjugated therapeutic agent. Also disclosed is a device for selectively removing anti-PEG antibodies from a blood stream and system incorporating the device.

Abstract: The present invention discloses an assay for determining the presence of an anti-PEG antibody in a biological sample. Embodiments according to this aspect of the present invention will generally have the steps of: (1) providing an antigen probe capable of forming an antibody-antigen complex with the anti-PEG antibody; (2) contacting the biological sample with the antigen probe under conditions favorable for formation of the antibody-antigen complex; and (3) analyzing the antigen probe, after having performed step (2), to detect for the presence of the antibody-antigen complex, wherein the presence of the anti-PEG antibody is determined if the antibody-antigen complex is detected. Also disclosed are methods for screening patients, methods for monitoring patients using assays of this invention and kits for performing thereof.

Abstract: A device mountable to a gutter for removing debris therefrom includes an elongated shaft with proximal and distal end portions positionable within the gutter, a plurality of debris-removing members mounted about the shaft and between the proximal and distal end portions thereof, a plurality of brackets spaced along the gutter for receiving the shaft therethrough, and a mechanism for operating the device causing the debris-removing members to rotate in a select direction as desired by a user. The operating mechanism may rotate the debris-removing members in an oscillating path or unidirectional path and a sensor may also be included to selectively toggle the device between on and off modes, without direct user input.

Abstract: Living cells modified at their surface with specially selected polymers are disclosed. A simple method to covalently attach specially selected PEG derivatives to the surface of RBC in aqueous media under mild conditions is a preferred example. The selected PEG-modification dramatically reduced aggregation and low shear viscosity of RBC resuspended in autologous plasma, and inhibited RBC agglutination by blood group-specific antibodies. The morphology and deformability of the PEG-treated cells were unaltered. The PEG coating of the RBC surface is applicable to the treatment of a variety of diseases characterized by vaso-occlusion or impaired blood flow, e.g., myocardial infarction, shock, and sickle cell disease.

Abstract: Living cells are modified at their surface with specially selected polymers. Covalently attaching specially selected polyethylene glycol (PEG) derivatives to the surface of red blood cells (RBC) in aqueous media under mild conditions is a preferred example. The selected PEG derivatives dramatically reduced aggregation and low shear viscosity of RBC resuspended in autologous plasma, and inhibited RBC agglutination by blood group-specific antibodies. The morphology and deformability of the PEG-treated cells were unaltered. PEG coating of the RBC surface is applicable to the treatment of a variety of diseases characterized by vaso-occlusion or impaired blood flow, e.g., myocardial infarction, shock, and sickle cell disease. An infusion solution is prepared containing red blood cells covalently bound to a PEG derivative having a molecular weight of between 2,000 and 5,000 Daltons and a PEG derivative having a molecular weight between 10,000 and 35,000 Daltons.
