Patent CA-2375297-A1 (CA)
Title: A complex containing lignan, phenolic and aliphatic substances from flax and process for preparing
Inventor: WESTCOTT NEIL D
IPC: A61K36/55
Filed: 2000-06-20
Abstract: A substantially pure complex is obtained from flaxseed containing secoisolariciresinol diglucoside, cinnamic acid glycosides and hydroxy methyl glutaric acid. The complex is produced by obtaining an aqueous aliphatic alcoholic extract from flaxseed or flaxseed meal and subjecting this aqueous extract to ultrafiltration whereby low molecular weight species remain with a filtrate and higher molecular weight species comprising the separated complex are retained. This complex is a valuable nutraceutical which may be incorporated in foodstuffs or consumed in the form of tablets or capsules.

Abstract: A surface stabilized, non-agglomerated silica is provided. The silica is prepared by the method of providing non-agglomerated silica, and then treating the surface of the silica, thereby substantially preventing agglomeration of silica. The surface of the silica may be treated with a hydrophobating agent, such as a silane, or an alcohol. Different embodiments of the invention illustrate that the hydrophobating agent or alcohol can be added at different points within the process of forming the surface stabilized, non-agglomerated silica. The surface stabilized, non-agglomerated silica has a size in the nanometer range. The surface stabilized, non-agglomerated silica can be used as an additive in any application that uses silica, such as reinforcing fillers for elastomeric compositions, foods, drugs, dentifrices, inks, toners, coatings and abrasives.

Title: Surgical stapling instrument
Inventor: CSIKY LASZLO
IPC: A61B17/115
Filed: 2002-11-28
Abstract: A surgical stapling instrument comprises a frame having a body portion and a handle. A staple fastening assembly is provided in the distal region of the instrument and includes a cartridge device, which comprises at least one closed row (10, 12) of staples, and an anvil. The anvil is movable relative to the cartridge device and is adapted to cooperate with the cartridge device for forming the ends of the staples exiting from the cartridge device. A knife, which has a closed cutting edge, is contained within the cartridge device and is positioned such that there is at least one closed row (10, 12) of staples on the outside of the cutting edge. It can be moved towards the anvil.      The line along which the closed row (10, 12) of staples is arranged has a stepped shape, leaving a plane perpendicular to the longitudinal axis of the staple fastening assembly, such that this line has a larger total length than the projection of this line onto this plane. This provides a greater flexibility of the anastomotic site and less tension during instrument removal, alleviating the incidence of clinical complications.

Abstract: La présente invention concerne un dispositif d'administration d'agent thérapeutique implantable ou insérable dont au moins une partie est enduite d'un revêtement empêchant la libération sensible d'un agent thérapeutique approximativement égal au pH physiologique ou inférieur à celui-ci, et permettant la libération sensible d'un agent thérapeutique approximativement égal au pH physiologique ou supérieur à celui-ci. Par ailleurs, cette invention concerne des revêtements destinés au dispositif d'administration d'agent thérapeutique implantable ou insérable. De préférence, ces revêtements sont des polymères obtenus pour contenir des fractions chargées cationiquement à un pH inférieur à leurs valeurs pKa. Par conséquent, ils peuvent attirer des agents thérapeutiques chargés négativement à des valeurs pH inférieures à leurs valeurs pKa, et deviennent essentiellement non chargés à des valeurs supérieures à leurs valeurs pKa, ce qui leur permet de libérer les agents thérapeutiques chargés négativement à de telles valeurs pH, qui sont approximativement égales au pH physiologique. Par ailleurs, l'invention concerne des méthodes d'obtention d'un polymère devant contenir de telles fractions, ainsi que des méthodes d'application d'un revêtement à base dudit polymère sur au moins une partie de la surface d'un dispositif d'administration d'agent thérapeutique implantable ou insérable.

Title: Method for producing tagatose crystals
Inventor: UNNO TAKEHIRO
IPC: C13B30/12
Filed: 2001-08-07
Abstract: A process for producing crystalline tagatose from an aqueous system containing no organic solvents. The process comprises adding seed tagatose crystals to a tagatose solution which has a solid concentration of 60 to 98 wt.% and in which the purity of the tagatose is 70%  or higher based on the solid matter and stirring and cooling the resultant mixture while keeping the degree of supersaturation with tagatose at 1.25 or lower to crystallize the tagatose. The tagatose solution preferably contains no organic solvents. It is desirable that part of the massecuite resulting from the crystallization be added to the mother liquor to semicontinuously or continuously produce crystalline tagatose. The crystalline tagatose yielded from the massecuite is preferably taken out by centrifugal separation or filtration and dried.

Abstract: A method of freeing stuck objects (16) from a bore (14) comprises running a string (12) into the bore (14), the string (12) including a flow modifier (22), such as a valve, for producing variations in the flow of fluid through the string, and a device (26) for location in the string and adapted to axially extend or contract in response to variations in the flow of fluid through the string. A portion of the string (12) engages the stuck object (16). Fluid is then passed through the string while applying tension to the string, whereby the tension applied to the stuck object varies in response to the operation of the flow modifier and the extending or retracting device.

Abstract: A homogeneous assay for determining the fumonisin content in grains uses the technique of fluorescence polarization. A grain extract is prepared by shaking a crushed grain sample with a solvent. A mixture is prepared by combining the grain extract with a tracer and with monoclonal antibodies specific to fumonisin. The tracer is able to bind to the monoclonal antibodies to produce a detectable change in fluorescence polarization. The tracer is prepared by conjugating fumonisin to a suitable fluorophore. The fluorescence polarization of the mixture is measured. The fumonisin concentration of the mixture may be calculated using a standard curve obtained by measuring the fluorescence polarization of a series of fumonisin solutions of known concentration.
