Abstract: Le procédé de la présente invention consiste à liquéfier par centrifugation la pulpe d'une tête d'agave broyée, à en extraire une solution de polyfructose, et à la concentrer pour produire un concentré de polyfructose. On élimine les petites particules par centrifugation et/ou filtration, et on élimine les colloïdes par coagulation thermique. On obtient ainsi un extrait de polyfructose partiellement exempt de corps solides en suspension. On traite ensuite l'extrait de polyfructose au charbon actif ainsi que par des résines cationiques et anioniques, ce qui donne un extrait de polyfructose déminéralisé et partiellement hydrolysé. On hydrolyse ensuite l'extrait de polyfructose partiellement hydrolysé avec des enzymes d'inuline jusqu'à obtenir un extrait de fructose hydrolysé. En concentrant l'extrait de fructose, on obtient un sirop de fructose.

Patent CA-2254354-A1 (CA)
Inventor: SCOBEY MICHAEL A
IPC: C23C14/00
Filed: 1996-06-10
Abstract: A method and apparatus for producing optical films on substrates having extremely high packing densities of the same quality as those films produced by ion beam sputtering including a vacuum chamber with a conventional magnetron sputtering system and unusually high speed vaccum pump means. The low pressure of inert gas created by said high speed vacuum pump means being in the range of 5 x 10-5 Torr to 2.0 x 10-4 Torr and the magnetron sputtering system being at least 20'' from said substrates. A gas manifold around the magnetron and target material confines the inert working gas in the vicinity of the magnetron and as the gas diffuses and expands into the chamber the high speed vacuum pump means removes the expanded gas from the chamber at the high speed. An ion gun directs ionized reactant gas toward the substrates which has the effect of improving film stoichiometry as well as reducing reactant gas at the magnetron. Multiple magnetron assemblies, multiple target materials and compound target materials may be used.

Abstract: La présente invention concerne un agent immunothérapeutique peptidique convenant particulièrement au traitement de tout patient souffrant d'allergie. L'invention concerne également un réactif destiné à un test de typage des molécules HLA de classe II concernant un patient et servant à sélectionner un agent immunothérapeutique peptidique convenant au traitement de n'importe quel patient souffrant d'allergie. Cet agent immunothérapeutique peptidique permet d'offrir à n'importe quel patient une immunothérapie peptidique optimale, ce qui fait qu'on est en droit d'attendre de nettes améliorations de telles immunothérapies peptidiques. En outre, il est possible d'élaborer un agent immunothérapeutique peptidique convenant au traitement de patients qui ne peuvent pas encore bénéficier des immunothérapies peptidiques en raison de la présence d'un antigène peptidique majeur détecté dans une population particulière de patients. Enfin, l'utilisation de l'antigène peptidique de l'invention facilite désormais le typage des molécules HLA de classe II dans le cas des patients souffrant d'une allergie.

Inventor: LAROSSA ROBERT ALAN
IPC: C12Q1/68
Filed: 1998-02-26
Abstract: A method is disclosed for the discovery of the site of action of xenobiotic compounds. The method involves subjecting a detector cell comprising a genotoxic-sensitive promoter operably linked to a luminescent reporter gene complex. Exposure of the detector bacteria to compounds that are genotoxic results in an increase in luminescence. Such compounds are grouped and may be analyzed for pharmaceutical activity. Exposure of the detector bacteria to active xenobiotics that are not genotoxic results in inhibition of bioluminescence or stable luminescence. Subjection of the detector bacteria to a screen such as nutritional reversal or genetic titration reveals the site of action of the compound.

Abstract: structure comprises, as the major component, a molded member of a thermoplastic resin composition or a fibrous material which may be a fiber of the thermoplastic resin composition, a yarn coated with the thermoplastic resin composition, a rope coated with the thermoplastic resin composition or a woven fabric coated with the thermoplastic resin composition. The thermoplastic resin composition contains an antifouling compound represented by the following formula (1):   (see formula 1) wherein Y represents hydrogen atom, an alkyl group, an alkenyl group or an aralkyl group, R represents hydrogen atom, a halogen atom or an alkyl group, R' represents hydrogen atom, a halogen atom or an alkyl group and R and R' may be bonded to each other to form a benzene ring. The leaching amount of the antifouling compound into an artificial sea water is controlled to 30 mg/cm3 or less at 25°C and 3 mg/cm3 or more at 15°C per a unit volume of the thermoplastic resin composition when integrated during initial 10 days after immersing the structure into the artificial sea water, thereby preventing the attachment of aquatic organisms for a long time. Also, the structure may be made water-permeable to have a water permeability of 1 cc/cm2~sec or more under a pressure of 18 cm water, thereby broaden the application field thereof.
