US Classification:

707803, 704 9

Abstract:

An advertisement placement method and system for relating an advertisement to a dataset based on a trainable semantic vector (TSV) associated with the dataset and respective semantic representations of the advertisements. The trainable semantic vector associated with the dataset is generated based on at least one data point included in the dataset and known relationships between predetermined data points and predetermined categories. A comparison process is performed to determine a similarity between the trainable semantic vector associated with the dataset and the semantic representation associated with each of the plurality of advertisements. The system selectively relates one or more of the advertisements with the dataset based on a result of the comparison process. The selected advertisement or advertisements may be displayed with the dataset.

International Classification:

A61K 3942
C07H 2104
C07K 1608

US Classification:

4241471

Abstract:

Chimeric cDNA for the expression of immunogenic polypeptides include the genetic epitopic determinants for a base infectious bursal disease virus strain and at least one other infectious bursal disease virus strain. The genetic epitopic determinants encode amino acids or amino acid sequences which define epitopes bound to by previously established monoclonal antibodies. The immunogens expressed by the cDNA may be employed to provide a vaccine against a plurality of IBDV strains. The epitopic determinant of IBDV lethal strains has been detected, and an immunogen for conferring immunity with respect thereto is disclosed. Similarly, a monoclonal antibody specific for IBDV lethal strains is identified, and a vaccine for passive immunization therewith is also disclosed. Immunogens exhibiting conformational epitopes, in the form of virus-like particles, are effective in the preparation of vaccines.

International Classification:

G01N 3353

C07K 1514
C12N 100

US Classification:

435 5

Abstract:

A method for determining the level of infectious bursal disease virus IBDV neutralizing antibody in poultry comprising a labeled monoclonal antibody R63 having the IBDV neutralizing capability of the monoclonal antibody expressed by hybridoma cell line ATCC HB-9490. Monoclonal antibody R63 is specific to all known IBDV strains and serotypes and competes only with itself and other antibodies recognizing the same neutralizing epitope present in poultry sera. In a competition assay, the increase in unbound labeled monoclonal antibody is an indication of the level of IBDV neutralizing antibody present in poultry sera.

C12N 1500
A61K 39395

US Classification:

530387

Abstract:

Monoclonal antibodies effective in preventing infectious bursal disease in chickens, by neutralizing one or more virus strains thereof, have been isolated and obtained from deposited hybridomas. Vaccination of an entire poultry population with a vaccine prepared from these monoclonal antibodies gives a uniform level of protection against all strains of infectious bursal disease tested. The monoclonal antibodies were effective in inducing priming for an active anti-viral response in a heterologous host.

International Classification:

A61K 3912
C12N 700

US Classification:

424 89

Abstract:

A new virus not neutralized or bound by monoclonal antibodies which bind and neutralize all IBD vaccines of current art, and capable of inducing infectious bursal disease in poultry is identified, in essentially pure form. A test kit, and assay for the presence of the virus is disclosed, together with the vaccine incorporating the virus.
