Title: An infective endogenous retrovirus in association with demyelinating diseases e.g. multiple sclerosis
Inventor: MOLLER LARSEN ANNE
IPC: C12N5/09
Filed: 2001-03-21
Abstract: Retroviral sequences were characterised by RT-PCR with gag and env primers on RNA from RT-positive retroviral particles produced by multiple sclerosis (MS) derived B-lymphoblastoid cell lines. Sequence variants with high homology to the potentially functional subgroup RGH of the human endogenous retrovirus RTVL-H/HERV-H family were found. The same sequences were also specifically found in the particulate fraction of a series of MS patient plasma samples and were absent in controls. South-Western blots demonstrated the presence of a nucleic acid binding protein, corresponding in size and function to the nucleocapsid protein, Gag NC, of other retroviruses. Indications for transmission of the retrovirus to mononuclear blood cells from healthy human individuals and non-human animals were found. Cell cultures derived from peripheral blood from MS patients contained 5-15 % CD3+ T-cells and a specific splice variant of the env sequence comprising a region of the pol region was identified in such cultures.

Title: Procedes d'analyse genetique au moyen de marqueurs d'adn qui utilisent des frequences haplotypes estimees et utilisations de ces procedes
Inventor: SCHORK NICHOLAS
IPC: G16B40/00
Filed: 2001-05-22
Abstract: L'invention concerne avant tout des procédés d'analyse génétique au moyen de marqueurs d'ADN qui utilisent des fréquences haplotypes estimées afin de tirer des inférences quant à la relation entre des haplotypes et des traits ou des maladies. Contrairement à beaucoup de procédés d'analyse d'haplotypes qui requièrent des informations de phase pouvant être difficiles à obtenir à partir d'échantillons d'espèces non-haploïdes, les procédés actuels sont basés sur des stratégies d'estimation des fréquences haplotypes à partir de données relatives à des génotypes diploïdes non en phase, en utilisant l'algorithme Estimation-Maximisation (E-M) pour palier au manque d'informations de phase. Ces fréquences haplotypes estimées peuvent alors être utilisée dans une variété d'analyses statistiques, y compris celles utilisées pour déduire l'existence d'un gène de maladie. Le procédé peut comporter : 1) l'estimation des fréquences haplotypes, 2) le calcul de statistiques de tests, et 3) la déduction d'inférences.

Abstract: A cyclone-type dust collecting apparatus having a dust removing portion for removing from the grill portion the dust and foreign substances that become attached to the grill portion of the grill member while the grill portion is rotated by the vortex air of the cyclone body.   The dust removing portion includes rotating means disposed at a lower portion of the grill member for rotation by an air current passing therethrough; a rotary member rotatably connected to the rotating means, and disposed separate from an end of the grill member by a predetermined distance; and a brush member having one side connected to the rotary member and the other side being disposed in contact with the grill portion of the grill member for removing the dust and foreign substances from the grill portion. As the cleaning operation starts, the brush member inside of the cyclone-type dust collecting apparatus is rotated by the vortex current generated therein, to remove dust or contaminants from the grill portion of the grill member. Accordingly, clogging of the gull portion of the grill member is prevented, and as a result, deterioration of the suction force and overload of the motor can be inhibited.

Patent CA-2419826-A1 (CA)
Inventor: LESANKO JOHN A
IPC: A01B15/16
Filed: 2003-02-25
Abstract: A coulter assembly has a resilient spring tine that bears against the compression face of the angled coulter during field operations to remove dirt clumps that otherwise inhibit the furrow-forming action of the coulter. A special spring coil mounting of the tine provides a lively vibratory action as the tine encounters various impact loads from different directions during field operations, thus rendering the tine essentially self cleaning insofar as trash accumulations are concerned. The angle of attack of the tine relative to the ground and the coulter can be readily adjusted without diminishing the vibratory action of the tine.

Patent CA-2428187-A1 (CA)
Inventor: HNATOVSKY CYRIL
IPC: G02B6/02
Filed: 2003-05-07
Abstract: A sub-micron structure is fabricated in a transparent dielectric material by focusing femtosecond laser pulses into the dielectric to create a highly tapered modified zone with modified etch properties. The dielectric material is then selectively etched into the modified zone from the direction of the narrow end of the tapered zone so th at as the selective etching proceeds longitudinally into the modified zone, the progressively increasing width of the modified zone compensates for lateral etching occurring closer to the narrow end so as to produce steep- walled holes. The unetched portion of the modified zone produced by translating the laser beam close to and parallel to the bottom surface of the dielectric can serve as an optical waveguide to collect light from or deliver light to the etched channel which can contain various biological, optical, or chemical materials for sensing applications.

Abstract: Compact low NO X gas burner apparatus and methods for discharging fuel gas and air mixtures into furnace spaces wherein the mixture is burned in folded flame patterns and flue gases having low NO X content are formed are provided. A burner apparatus of the invention is basically comprised of a housing having a burner tile attached thereto and means for introducing air therein. The burner tile has an opening therein with a wall surrounding the opening which extends into a furnace space. The exterior sides of the wall are divided into sections by radially positioned baffles with alternate sections having the same or different heights and slanting towards the opening at the same or different angles. Primary fuel gas mixed with flue gases and air is discharged through the burner tile. Secondary fuel gas is discharged adjacent to the external slanted wall sections whereby the secondary fuel gas mixes with flue gases in the furnace space. The resulting fuel gas-flue gases streams mix with the fuel gas-flue gases-air mixture discharged through the burner tile and the resulting mixture is burned in the furnace space.

Abstract: The present invention provides an elongated lighting apparatus for use in environments subject to temperature fluctuations, wherein the lighting apparatus can be illuminated along its entire length during operation. The elongated lighting apparatus comprises several components which operate in harmony in order to provide this functionality.  The lighting apparatus comprises at least two elongated tubular members fabricated from a material that allows the passage of light therethrough. These elongated tubular members are fixedly mounted on a surface in an end to end configuration, separated by a region enabling the thermal expansion/contraction of the members. Slidably positioned inside each tubular member is a substrate having a plurality of light emitting devices integrated thereon for providing illumination. The open ends of the elongated tubular members are enclosed by end caps that enable the sealing of these ends of the members. At least one of these end caps has a protrusion therein that projects towards the region of separation and this protrusion is fabricated from a material that allows the passage of light therethrough.  Positioned proximate to a protrusion in an end cap is at least one of the plurality of light emitting devices, wherein this protrusion provides a means for light diffusion into the region separating the elongated tubular members, thereby illuminating this region.  Enclosing the region between the elongated tubular members is a flexible interconnector also fabricated from a material that allows the passage of light therethrough. The flexible interconnector provides a means for the visual concealment of the region separating the adjacent members. The lighting apparatus further comprises electrical interconnection between the light emitting devices and an external power source thereby providing a system for the energization of the light sources.
