Title: Attenuated rabies virus with nucleoprotein mutation at the phosphorylation site for vaccination against rabies and gene therapy in the cns
Inventor: FU ZHEN FANG
IPC: C12N15/86
Filed: 2002-07-22
Abstract: A mutant virus is provided which contains a mutation at a phosphorylation site in one or more of the proteins of the virus, which mutation causes the virus to be attenuated, and therefore, an improved vaccine composition can be produced therewith. The invention also relates to vaccine compositions which contain the mutant virus, as well as to methods of inducing an immune response, and of protecting mammals from infection by rabies virus. Also included in the invention are methods of producing the mutant virus and mutant viral proteins, including producing the mutant virus in a host cell which produces or even overproduces a wild-type counterpart of the mutant viral protein, which complements the other viral proteins such that production of the mutant viral particle is optimized. The invention also includes those host cells in which viral production is optimized, as well as vaccine compositions including the viral proteins, either alone or in combination with the intact virus, and to methods of inducing an immune response or protecting a mammal from infection, using the same. Also included in the invention are vectors suitable for delivering a gene to a cell of a human or animal, as well methods of delivery thereof.

Abstract: ABSTRACT OF THE DISCLOSURE   The invention provides a television receiver system for collecting and storing information in the form of coded characters received separately from any wide-band picture signals.  In any television system there are periods when no such picture signals are transmitted.  The separately received information may be received during such periods of an actual television transmission being viewed or they may be received on a separate channel.    According to the invention, the system comprises selector equipment for selecting the information to be stored from a single information channel or a small number of information channels and routeing the selected information to a storage device, and a reading device operable, when actuated, to read the information from the storage device repeatedly and feed it, via a character generator, for display by an intensity modulated raster.    The information to be displayed may be a page selected by the viewer from a set of pages transmitted repeatedly in turn.          This selected information is held by the storing device for prolonged display.

Abstract: CORONA REACTION METHOD            Abstract of the Disclosure Corona discharge reactions are efficiently conducted by passing a reactant gas through a corona discharge gap in which pulsed electrical energy is dissipated to accelerate electrons to a productive energy level, and eliminating gas ions from the gap to minimize non-productive energizing of the ions prior to additional corona discharge   In one preferred practice of the process a selective ion neutralization potential is applied to eliminate the non-productive gas ions between corona pulses.   In other preferred practices, a reactant gas which is exposed to corona is removed from the corona zone after limited exposure to corona to permit recombination of the heavy gas ions prior to additional exposure to corona and/or an ion neutralizing component is added to the reactant gas stream.
