Title: Production of helper dependent adenovirus vectors based on use of endonucleases
Inventor: GRAHAM FRANK L
IPC: C12N5/10
Filed: 2000-02-15
Abstract: The present invention relates to methods for efficient and reliable construction of adenovirus vectors which contain and express foreign DNA and are useful cells, for vaccines and for gene therapy. The invention provides for the growth and purification of adenovirus vectors (belper dependent vectors or HDVs) from which all or most of the viral genes have been removed. The vector system described herein is a new method designed to eliminate helper viruses from the final HDV preparation by cleavage of the helper virus DNA with an endonuclease, alone or in combination with other methods known to limit the level of helper virus contamination of helper dependent vector preparations. The disclosed methods and compositions also provide for regulated control of gene expression.

Abstract: La présente invention concerne des compositions qui conviennent comme shampooing, et en particulier celles qui, en plus de laver et de tonifier les cheveux, ont été développées en vue de traiter une infection en suspension dans les cheveux, ou une maladie de la peau du crâne. Un premier aspect de cette invention concerne une composition de shampooing liquide et non aqueux qui comprend au moins un détergent, au moins un principe actif incompatible avec l'eau, un agent d'étoffement organique et des excipients pour shampooing, ledit agent d'étoffement organique étant miscible dans l'eau, avec le détergent et avec les excipients pour shampooing. On a été surpris de constater que le fait de remplacer un agent d'étoffement organique tel que l'eau par un composé organique compatible avec les principes actifs non soluble dans l'eau, mais qui est lui-même miscible dans l'eau et avec les détergents, peut produire un shampooing liquide et non aqueux acceptable du point de vue cosmétique et esthétique, et en particulier l'un d'entre eux qui possède des propriétés moussantes.

Title: Passively energized floating guide
Inventor: SUK ANTON
IPC: G03B27/52
Filed: 2001-05-15
Abstract: This is a passively energized floating guide for a parked head scanner having a scanning glass slit.      This floating guide applies pressure to the original papers crossing the scanning glass slit in order to wipe the scanning glass slit, and keep it free from contamination.      The floating guide comprises a wiper bar which is pivotally mounted above the scanning glass slit such that it extends from end to end of the scanning glass slit, and it rests on the scanning glass slit when at rest. The weight and pivot point for the wiper bar are chosen such that the force of the original paper rotates the wiper bar and causes the wiper bar to press down on the original as it passes between the wiper bar and the scanning glass slit with sufficient force to clean the glass, but not enough force to jam the paper. This is the case even for lightweight papers. After the paper has passed, the wiper bar pivots back to its initial position.

Patent CA-2385027-A1 (CA)
Inventor: NELSON TIMOTHY SCOTT
IPC: A61M37/00
Filed: 2000-10-03
Abstract: The invention provides a means of closed exchange of implanted medical device components. An exchanger is brought into contact with the implanted medical device "in situ". The component is withdrawn from the implanted device and brought into a closed chamber of the exchanger. Without breaking the contact between implanted device and exchanger, the replacement component is then moved from its position in the exchanger, and inserted into the correct position in the implanted device. The surfaces of the implanted device are not brought into contact with the outside environment, thereby minimizing the possibility of introducing contaminants into the body during the exchange process. The invention is particularly useful for devices that are difficult to position and reposition, thus making it advantageous to exchange only an expended component, rather than the entire device.

Abstract: An on line interactive advertising system enables viewing of advertising by a consumer who receives data and/or images over a communication system such as the internet. The consumer may at their option simultaneously receive advertising. The consumer has a consumer station which communicates with a host having a website. An advertising provider communicates with the host and, when the consumer has elected to do so, with the consumer station via the host. The host sends random invitations to view advertising. These may be in the form of a flashing icon which requires a response from the consumer. The consumer station receives advertising material without requiring software to be downloaded or installed in it. When the consumer elects to view this advertising, the consumer receives rewards, credits or benefits commensurate with the length of time that the advertising is viewed. The reward may be reimbursement for the costs of the internet time.
