Abstract: Viruses are modified by coupling a polymer such as polyethylene glycol to obtain polymer-modified viruses that can exhibit reduced antigenicity while retaining infectivity, and which may exhibit increased circulation time in vivo. The polymer may be directly covalently attached or indirectly covalently attached via an intermediate coupling moiety to the virus. The polymer may also be indirectly noncovalently attached to the virus via a ligand such as an antibody having specificity for a viral surface component. To prepare the polymer-modified virus, the polymer is activated and coupled to the virus. A preferred activated polymer is tresyl-monomethoxypolyethylene glycol having an average molecular weight of about 5000 daltons. The polymer-modified viruses have utility for therapeutic and diagnostic in vivo applications, and may be used to introduce a transgene into a target cell by infection, or be administered to a subject having a tumor where the polymer-modified virus localizes to the tumor.

Abstract: The object of the present invention is to promote warming-up operation in a cooling water flow control system of an internal combustion engine. A flow control valve is provided at a junction of a radiator passage and a bypass passage. Radiator flow rate and bypass flow rate of the flow control vale are controlled by detecting engine outlet water temperature, radiator outlet water temperature, number of revolutions of engine, and suction pipe negative pressure. The cooling water in the bypass passage passes through a throttle body, and flow rate is controlled to a totally closed flow rate or a micro-flow rate in the warming-up operation, and this contributes to the promotion of the warming-up operation.
