    摘要: Attenuated respiratory syncytial virus (RSV) and vaccine compositions thereof are produced by introducing specific mutations associated with attenuating phenotypes into wild-type or RSV which is incompletely attenuated by cold-passage or introduction of mutations which produce virus having a temperature sensitive (ts) or cold adapted (ca) phenotype. Alternatively, recombinant RSV and vaccine compositions thereof incorporate attenuating and other mutations specifying desired structural and or phenotypic characteristics in an infectious RSV. Recombinant RSV incorporate desired mutations specified by insertion, deletion, substitution or rearrangement of a selected nucleotide sequence, gene, or gene segment in an infectious RSV clone. The immune system of an individual is stimulated to induce protection against natural RSV infection, or multivalently against infection by RSV and another pathogen, such as PIV, by administration of attenuated, biologically derived or recombinant RSV.

    摘要: An integrated buffer circuit configuration has two inverters which are mutually connected in series. A circuit node lies between the two inverters. At least the first inverter is a CMOS inverter for an input signal IN. The CMOS inverter has an n-channel transistor which is connected to a first supply potential. The source of a p-channel transistor is connected with a constant current source. A first enable transistor is connected between the n-channel transistor of the first inverter and the circuit node. A second enable transistor is connected in parallel to the configuration formed by the constant current source and the p-channel transistor of the first inverter. The gates of the enable transistors are connected with the enable input of the buffer circuit. An enable signal present at the enable input makes it possible to deactivate the buffer circuit in the case of disturbances with a known course over time. A MOS-transistor may function as the constant current source. The MOS-transistor is then connected to a second supply potential and its gate lies at reference potential with a value with always has a constant difference with respect to the second supply potential. During operation, the MOS-transistor is conducting.

    摘要: An integrated circuit for generating a reset signal includes terminals for a first and a second supply potential. A serial RC network is connected between the terminals. The RC network has an ohmic component, a capacitive component and a first circuit node of the integrated circuit connected between the components. An initializing circuit is connected parallel to the RC network. The initializing circuit has an output forming a second circuit node of the integrated circuit carrying a potential with a maximum value specified by dimensioning the initializing circuit, when the first supply potential is applied. An inverter circuit is connected between the first circuit node and the terminal for the second supply potential in terms of supply voltage. The inverter circuit has an input connected to the second circuit node and an output forming a third circuit node of the integrated circuit. A transistor has a source-to-drain path connected between the second circuit node and the terminal for the second supply potential and has a gate connected to the third circuit node. An additional inverter has an input at the third circuit node and an output forming a fourth circuit node of the integrated circuit at which a reset signal is present during operation.
