Title: Novel mutants of gram negative mucosal bacteria and application thereof in vaccines
Inventor: VAN DER LEY PETER ANDRE
IPC: C12N/
Filed: 1997-08-21
Granted: 2011-04-05
Abstract: It is possible to inactivate the early stage of lipid A synthesis of mucosal gram negative bacteria without compromising cell viability. In particular the lpxA gene in N. meningitidis was mutated and resulting lpxA knockout mutants were found to be completely lipopolysaccharide(LPS)-deficient. The major outer membrane proteins (OMPs) were detected in normal amounts. The finding provides important implications for understanding of structure and biogenesis of the outer membrane. On a practical level, the availability of LPS-deficient mutants of pathogenic mucosal bacteria such as N. meningitidis opens up new avenues to vaccine development. It enables easy isolation of endotoxin-free purified proteins, outer membranes or even whole-cell preparations for use in immunisation.

Abstract: L'invention concerne un procédé et un appareil pour la transmission d'un signal optique. Le procédé consiste à générer un signal optique qui comprend une pluralité de canaux optiques, numérotés séquentiellement de 1 à N, de la longueur d'onde la plus faible jusqu'à la longueur d'onde la plus élevée. Un état de polarisation de canaux de nombre impair prédéterminés est orienté de manière à être sensiblement orthogonal à un état de polarisation de canaux de nombre pair prédéterminés, en dirigeant les canaux de nombre impair prédéterminés et les canaux de nombre pair prédéterminés, à travers des entrées de polarisation orthogonales d'un coupleur de polarisation. Les canaux de nombre impair et les canaux de nombre pair peuvent être dirigés à travers, respectivement, des premiers et deuxièmes combineurs de longueur d'onde, avant d'orienter leurs états de polarisation. La relation orthogonale entre les états de polarisation des canaux de nombre impair et de nombre pair, limite avantageusement les produits de mélange quatre ondes qui peuvent être générés dans le transmetteur optique et le parcours de transmission optique auquel il est généralement couplé.

Abstract: An apparatus, program product, and method restrict access to objectionable audio content in an audio or audio/video transmission using sound recognition. Sound recognition may be performed, for example, to detect and control access to objectionable non- spoken audio content, e.g., by detecting violent sounds such as screams, explosions, gun shots, sirens, punches, kicks and/or other non-spoken content such as sexually-suggestive sounds. In addition, occurrences of objectionable audio content detected in an audio transmission may be tracked so that access to the audio transmission may be controlled responsive to the identification of multiple occurrences of objectionable audio content. Furthermore, access control over detected objectionable audio content in an audio transmission may result in inhibition of access to a program associated with the audio transmission.
