Title: Methods of diagnosing clinical subtypes of crohn's disease
Inventor: TARGAN STEPHAN
IPC: C12Q1/68
Filed: 1997-04-11
Abstract: Provided herein is a method of diagnosing a clinical subtype of Crohn's disease (CD) by determining whether perinuclear anti-neutrophil antibody (pANCA) is present in a patient with CD, where the presence of pANCA  indicates a clinical subtype of CD with features of ulcerative colitis (UC). The present also provides a method of diagnosing clinical subtypes of Crohn's disease in a patient with CD by determing whether pANCA or speckling anti-pan polymorphonuclear antibody (SAPPA) is present in the patient with CD, where the presence of pANCA indicates a clinical subtype of CD with features of ulcerative colitis and where the presence of SAPPA indicates a clinical subtype of CD having perforating, fistulizing or small bowel obstructive disease. The invention further provides a method of diagnosing clinical subtypes of Crohn's disease in a patient with CD by determining the presence or absence of ANCA, pANCA and SAPPA in the patient with CD and determining the presence or absence of anti-Saccharomyces cerevisiae antibodies (ASCA) in the patient with CD, where the presnece of pANCA combined with the absence of ASCA  indicate a clinical subtype of CD with features of UC, the presence of SAPPA indicates a clinical subtype of CD having perforating or fistulizing disease or small bowel obstructive disease, and the presence of ASCA combined with the absence of ANCA indicates a clincial subtype of CD lacking features of ulcerative colitis and having perforating or fistulizing disease or small bowel obstructive disease. Kits for diagnosing clinical subtypes of Crohn's disease, which contain neutrophil and antigen specific for ASCA, also are provided.

IPC: H01H1/00
Filed: 1997-09-10
Abstract: La conception des commutateurs électriques fonctionnant sous charge (soumis au passage d'un courant) nécessite le remplacement du contact électrique lorsque ses fonctionnalités baissent au-dessous d'une limite acceptable en raison de l'érosion et de l'usure dues à la formation d'étincelles et à des températures élevées. On introduit une certaine quantité d'un élément ou d'une substance trace (18) à une profondeur qui reflète le degré d'érosion ou d'usure nécessitant le remplacement du contact. Sous l'effet de l'érosion ou de l'usure, ladite quantité de l'élément trace (18) est relâchée dans l'huile ou dans un autre média entourant le contact, indiquant ainsi que l'usure est devenue excessive. En option ou en guise de complément, une quantité d'un élément trace se trouvant à la surface d'un ou de plusieurs composants du commutateur électrique peut se libérer dans le média environnant une fois qu'une température présélectionnée est atteinte.

Patent CA-2270346-A1 (CA)
Inventor: ASHER SANFORD A
IPC: G01N31/22
Filed: 1997-10-24
Abstract: Novel sensor devices composed of a crystalline colloidal array (CCA) polymerized in a hydrogel are disclosed. The hydrogels are characterized as being capable of shrinking and swelling in response to specific stimuli applied thereto. As the hydrogels shrink or swell, the lattice structure of the CCA embedded therein changes, thereby changing the wavelength of light diffracted by the CCA. Thus by monitoring the change in diffracted wavelength, the concentration of a stimulus is determined. The gels can be modified to sense numerous different stimuli. The sensor devices are specific in that they are modified to react with only one species or family of species. These sensors have various applications in areas including, for example, environmental and chemical systems, chemomechanical systems, sensor devices and medical diagnostic tools. Various methods for making and using these devices are also disclosed.

Patent CA-2273933-A1 (CA)
Title: Improved plastic bag
Inventor: DOBRESKI DAVID V
IPC: B65D33/25
Filed: 1997-10-22
Abstract: The present invention improves performance of the side and/or fin seals (16) of plastic bags through the use of resins that have a narrow molecular weight distribution or polydispersity. The performance of the side seal and/or fin seal of a plastic bag is improved by using body panels (25, 26) which comprise a first resin, and optionally, a second resin. The first resin is preferably prepared in the presence of a single site catalyst. The first resin has a polydispersity of from about 1 to about 4, a melt index of from about 0.2 to about 20, and a melt flow ratio (I20/I2) of from about 12 to about 35. The use of such first resins results in side and fin seals which are stronger, tougher, and less likely to leak. The second resin is a polymer such as LDPE, LLDPE, or a blend thereof. In body panels comprising both a first and a second resin, the first resin may be coextruded with LDPE or LLDPE as a thin layer of the body panel or the first resin may be blended with the LDPE and/or LLDPE.

Abstract: Dispositif de pulvérisation de liquide à deux étages, comportant une zone de distribution présentant un îlot (41), un orifice de sortie (47) et un oscillateur (33) fluidique actionnant cette zone de distribution. L'amélioration du dispositif de pulvérisation se caractérise par un fonctionnement à basse pression permettant de réaliser une couverture complète d'une zone au moyen de gouttelettes sensiblement uniformes, toutes ces goutelettes arrivant sur la surface de travail choisie sans rebondir. L'oscillateur fluidique comporte une chambre d'oscillation (33), une buse de propulsion (31) pour introduire un jet de liquide depuis une source dans la chambre d'oscillation. La chambre d'oscillation est formée de manière à générer deux tourbillons de commande alternés qui permettent d'éviter dans une large mesure que le jet ne se dépose sur les parois lorsqu'il traverse la chambre d'oscillation et ne provoque un épaississement de la fin du jet oscillatoire. Un orifice de sortie conduit de la chambre d'oscillation à la zone de distribution, le jet balaye rythmiquement par pulsations complètes de chaque côté de l'îlot et forme une nappe à l'orifice de sortie. Cette nappe est ondulée ou balayée rythmiquement dans l'air ambiant pour former des gouttelettes uniformes. Une fente transversale définit la limite latérale du mouvement de balayage de la nappe.
