摘要:
Feed water comprising an aqueous salt solution is supplied to an anode chamber (12) and to a cathode chamber (14). The feed water is cathodically electrolyzed in the cathode chamber (14) to produce alkaline electrolyzed water (catholyte) and is anodically electrolyzed in the anode chamber (12) to produce electrolyzed water (anolyte) whose pH is modified. A portion of alkaline catholyte from the cathode chamber (14) is recycled back to the feed water during continuous electrolysis to provide a blend of feed water and alkaline catholyte to the anode chamber (12) to control pH of the anodically electrolyzed water therein to provide more stable bactericidal activity thereof over time.

This invention provides vectors and methods for the stable introduction of exogenous nucleic acid sequences into the genome of avians in order to express the exogenous sequences to alter the phenotype of the avians or to produce desired proteins. In particular, transgenic avians are produced which express exogenous sequences in their oviducts and which deposit exogenous proteins into their eggs. Avian eggs that contain exogenous proteins are encompassed by this invention. The instant invention further provides novel forms of interferon and erythropoietin which are efficiently expressed in the oviduct of transgenic avians and deposited into avian eggs.

The present invention provides isolated and recombinant avian nucleic acid molecules comprising at least one avian MAR and an avian nucleic acid sequence encoding an ovalbumin transcriptional regulatory region. The isolated nucleic acid of the present invention is useful for reducing chromosomal positional effects upon the transcription of a transgene operably linked to the ovalbumin transcriptional regulatory region and transfected into a recipient avian cell The recombinant nucleic cid molecules of the present invention may further comprise a polyadenylation signal sequence or an avian 3' domain, and optionally, an internal ribosome entry site for expression of an operably linked heterologous nucleic acid insert in a transfected avian cell.
摘要:
A method for identifying active site inhibitors of scission enzyme that cleaves the backbones or side groups of peptides, and for using the resultant inactivators to inhibit the target scission enzyme. Kinetic assays are employed to identify peptide substrates that tightly bind to the active site of the target protease but that are not easily cleaved. These noncleavable but tightly binding substrates are optionally structurally modified to yield inhibitory compounds with optimized properties. Additionally these substrates exhibit apparent specificity for a transition state or ground state configuration of the protease.
摘要:
The present invention provides a vaccine which is protective against avian polyomavirus infection in a bird which is classified as being a member of the Psittaciformes order which comprises an immunogenic amount of a modified live avian polyomavirus in a pharmaceutically acceptable carrier. Methods are also provided for preventing avian polyomavirus infection in a bird, or in several different species of birds, classified as being a member of the Psittaciformes order, comprising administering a vaccine comprising an immunogenic amount of a modified live avian polyomavirus and a pharmaceutically acceptable carrier. A preferred embodiment provides a modified live avian polyomavirus vaccine for prevention of wild-type infection in a Budgerigar, lovebird or Cockatiel.
