Abstract:
The invention relates to uses of nitric oxide gas to inactivate any whole, part or subunit of a microbe, such as a virus. Such an inactivated or attenuated virus after treatment with NO gas may be used in formulations for a vaccine. Nitric oxide may be administered directly to create a vaccine through in vitro and/or in situ or by direct administration in vivo. Also provided are methods for treating patients with viral infections through the inhalation of nitric oxide gas.
Abstract:
The present invention relates to improved inactivated feline calicivirus (FCV) vaccines. The invention also provides a process for producing stabilized inactivated FCV, and the use of such stabilized inactivated FCV, in the production of FCV immunogenic compositions. The invention further provides methods of inducing an immune response in an animal of the Felidae family, preferably a cat, using the immunogenic compositions according to the invention.
Abstract:
An antigenic and immunogenic composition of predetermined inactivated strains of human immunodeficiency virus (HIV) is disclosed. Inactivation is through psoralen and ultraviolet radiation; the composition is rendered more effective by the removal of structural features of HIV that interfere with immune response. In particular, sialic acid is removed to enhance immune recognition of the composition and to impair Complement Factor H binding. CD55 and CD59 are also removed to prevent the binding of Complement Factor H. Determination of strains for inactivation may be though immunotherapeutic genotyping or probabilistic assessment of risk of exposure.
Abstract:
The present invention relates to a novel method for improving the viral safety of liquid Factor VII compositions, in particular those comprising active Factor VII polypeptides (a Factor VIIa polypeptide).
Abstract:
The present invention relates to methods of inactivating non-enveloped viruses, such as, erythroviruses in protein preparations. The invention relates to in particular inactivating human erythroviruses in protein preparations isolated from human plasma.
Abstract:
A vaccine for protecting a horse against diseases associated with EHV-1 and/or EHV-4 is provided. The vaccine commonly includes inactivated EHV-1 (e.g., chemically inactivated EHV-1 KyA virus), using ethylenimine and an adjuvant. The adjuvant can include a cross-linked olefinically unsaturated carboxylic acid polymer which may have bioadhesive properties. The vaccine may also include antigens against other equine pathogens such as inactivated EHV-4 and inactivated A1 and/or A2 strains of equine influenza virus. Methods for protecting horses against diseases associated with EHV-1 and/or EHV-4 and methods of producing the equine herpesvirus vaccine are also provided.
Abstract:
The present invention provides methods for detecting and adjusting replication of hepatitis B virus, and for preparing mutated virus strains with altered replication efficiency. The present invention uses various primers which are designed on the basis of polymerase-encoding nucleotide sequence of the strains, in combination with endonuclease digestion and polymerase chain reaction, to replace polymerase genes in genomes of various hepatitis B virus strains and respective fragments of the genes. The present invention also analyses the replication function of new recombined polymerase genomes. The present invention can be used to find new functional regions in the polymerases, and to design corresponding drug or diagnostic reagent, said drug can inhibit replication of hepatitis B virus.
Abstract:
The present invention discloses positive control material for nucleic acid amplification based detection of microorganisms in biological samples. The control material comprises purified microorganism that is rendered non-infectious but is amenable to nucleic acid amplification. Also disclosed is a process for making and using the control material.
Abstract:
The present invention provides for the use of chloramines formed from hypochlorous acid and an amine-containing compound as antiviral agents and as sterilizing agents for blood. The chloramines are active against viruses, including retroviruses, having cysteine-rich regions. Such viruses include HIV. The preferred chloramine is taurine-chloramine. The chloramines may be used as a sterilizing agent for blood and blood products including whole blood, packed red blood cells, and serum, and may be used in vitro , or ex vivo .
