Patent CA-2413660-A1 (CA)
Inventor: VOORHEES JOHN J
IPC: A61K8/35
Filed: 2001-07-06
Abstract: UVB radiation of about 300-310 nm wavelength and UVA radiation of about 380-390 nm wavelength, each of which exists in solar light, induces MMPs (matrix metalloproteinases) in human skin that degrade the collagen of the dermal matrix. This degradation contributes to photoaging of human skin, which can be prevented by blocking the wavelengths of solar radiation. In contrast, diseases that result in the overproduction of collagen can be treated by exposing the affected with to radiation having wavelengths in those regions, for these wavelengths not only induce MMPs but also inhibit collagen biosynthesis. For lighter skinned people so affected, the UVA wavelengths are preferred because of the reduced amount of erythema, whereas dark skinned people can be treated with the UVB radiation because they generally do not suffer from erythema.

Abstract: L'invention concerne un procédé de détermination des propriétés relatives à un puits en sous pression, consistant à induire des variations de pression dans un fluide à l'intérieur d'un puits, à mesurer ces variations de pression, et à calculer une pression interstitielle d'au moins une formation de production de fluide. Les variations de pression provoquent une variation de débit provenant de formations sur une longueur de trou de sonde, et provoquent ainsi une variation du débit de production du puits. Ces variations de pression sont employées pour calculer la pression interstitielle. Les variations de pression dans le fonds de puits annulaire sont induites par modification du débit de fluide de forage, de la densité de ce fluide de forage ou induites par application d'impulsions acoustiques au fond du puits. La pression interstitielle, la perméabilité et la porosité des formations sont obtenues sous la forme d'un profil en temps réel sur la longueur du trou de sonde.

Abstract: Apparatus and methods for removing malodor from the air, particularly from confined spaces are disclosed. Such devices and methods are useful for example for storing and preserving food in closed compartments such as refrigerators.  The apparatus and methods utilize baking soda as the odor removing substance, either alone, or in combination with another odor removing substance, which may include activated carbon. In one embodiment, the apparatus has a detachable cartridge member which contains baking soda. In one version of this embodiment, the detachable cartridge member is used with an air moving member that draws air through the detachable cartridge member. In one embodiment, the method involves using a detachable cartridge member with an air moving member in one confined space, and using another cartridge member without the air moving member in another compartment of the confined space. In another embodiment, may also be used for emitting a scent, or other substance (including, but not limited to insecticides, air fresheners, deodorants, aromacology, aromatherapy, or any other odor that acts to condition, modify, or otherwise charge the atmosphere or to modify the environment) into the air.
Patent CA-2437498-A1 (CA)
Inventor: PAN SHEN QUAN
IPC: C12Q1/02
Filed: 2002-02-05
Abstract: This invention relates to methods an kits for determining the level of H2O2 inside a cell, an for determining whether a test compound has ability to scavenge a reactive oxygen species (ROS). The methods an diagnostic kits of this invention employ a cell containing a promoter which is inducible by an ROS, such as the H2O2-inducible KatA promoter of Agrobacterium tumefacines; the promoter is used to drive expression of a reporter gene. The expression level of the reporter gene correlates with the level of ROS, specifically H2O2, inside the cell. When the cell is exposed to a test compound, either intra-cellularly or extra-cellularly, if the level of ROS-inducible expressi on of the reporter is reduced, then this indicates that the test compound is a scavenger of the ROS. The methods of this invention may also be used to sele ct for new or improved ROS scavengers by expressing a library of test scavenger s in cells which express a reporter from a ROS-inducible promoter and selectin g for those cells whose level of ROS-inducible expression of the reporter is reduced. The cells which express a reporter from a ROS-inducible promoter ma y have a modified genetic background to reduce their naturally occurring ROS- scavenging ability.

Title: Replicons derived from positive strand rna virus genomes useful for the production of heterologous proteins
Inventor: ESCRIOU NICOLAS
IPC: C12N15/86
Filed: 2002-05-23
Abstract: The present invention relates to replicons or self-replicating RNA molecules , derived from the genome of cardioviruses and aphtoviruses, which can be used to express heterologous proteins in animal cells. When injected in an animal host, for example in the form of naked RNA, these replicons permit the translation of the encoded heterologous protein. If the encoded heterologous protein is a foreign antigen, these replicons induce an immune response against the encoded heterologous protein. The invention uses cardiovirus and aphtovirus genomes to construct these replicons. The invention demonstrates that these replicons, when injected as naked RNA, can induce immune response s against a replicon-encoded heterologous protein in an animal recipient witho ut the help of any kind of carrier or adjuvant.
