Abstract: The invention is directed to a single-step method for rapidly and efficiently preparing protein-polymer conjugates, including an insulin-polymer conjugate. According to the method of the present invention, a protein and hydrophilic polymer are contacted in the presence of at least one organic solvent and at least one metal chelator, under conditions that promote the formation of a conjugate of the protein and polymer. Thus, the invention is directed to the site-specific modification of selected proteins, such as insulin, with poly(ethylene glycol) at residue PheB1. The invention also provides a pharmaceutical formulation for encapsulating the conjugate in a biodegradable polymer.

Abstract: An apparatus for installing multiple utility meters is provided. The apparatus may be attachable to an existing setter in place of a utility meter. The apparatus includes connectors for a plurality of utility meters, wherein one of the utility meters attaches such that intake into the meter and outtake out of the meter utilize the setter. The apparatus may include connectors for one or more additional meters and secondary outtakes for each of the additional meters.

Abstract: Formulations for controlled, prolonged release of bioactive molecules such as therapeutic proteins, peptides and oligonucleotides have been developed. These formulations are based on solid microparticles or nanoparticles formed of the combination of biodegradable, synthetic polymers such as poly (lactic acid) (PLA), poly (glycolic acid) (PGA), and copolymers thereof. Bioactive molecules are coupled to hydrophilic polymers such as polyethylene glycol or polypropylene glycol and formulated to provide controlled release. The bioactive molecules are more stable, less immunogenic and have improved release rate profiles with lower burst levels and increased drug loading relative to the same bioactive molecules lacking coupled hydrophilic polymers. The controlled release formulations can be administered by injection, by inhalation, nasally, or orally.

Abstract: Embodiments of the present invention provide a fuel supply system for combustion engines, whereby the temperatures of an oxidizer and fuel may be increased so that the temperatures approach but do not achieve an auto-ignition temperature for the fuel charge. The fuel charge may result in substantial improvements in fuel efficiency.

Abstract: Pharmaceutical compositions comprising a nucleic acid, a gene delivery polymer, and at least one adjunctive chemotherapeutic drug for the treatment of mammalian cancer or hyperproliferative disorders and methods of using thereof for the treatment of mammalian cancer or hyperproliferative disorders by intratumoral, intraperitoneal or systemic injection.

Abstract: A method for preparing biodegradable, biocompatible microparticles. A first phase is prepared that includes a biodegradable, biocompatible polymer, an active agent, and a solvent. A second phase is prepared. The first and second phases are combined to form an emulsion in which the first phase is discontinuous and the second phase is continuous. The discontinuous first phase is separated from the continuous second phase. The residual level of solvent in the discontinuous first phase is reduced to less than about 2% by weight.

Abstract: A fuel supply assembly providing vaporized fuel to an engine wherein a quantity of liquid gasoline fuel is controllably heated for a desired vapor emission from the liquid fuel, and a conduit arrangement conducts the vapor, intermixes it with ambient air and conveys the intermixture to the engine's combustion chamber. A sensor in the engine exhaust monitors the hydrocarbon content of the exhaust and control valving controls the vapor to air intermixture in response to the monitor for maintaining a desired intermixture that produces the desired hydrocarbon content.
