Patent CA-2307593-A1 (CA)
Inventor: GERBERICH H ROBERT
IPC: C07C69/63
Filed: 1997-10-31
Abstract: The present invention provides an improved method for the preparation of carboxylic acid esters of alkylene glycol monoalkyl ethers by the acid catalyzed esterification of the monoalkyl ether with a carboxylic acid. In a preferred embodiment of the invention, the carboxylic acid and alcohol are reacted in a reactor/column and the resulting ester product is distilled into an overhead decanter/extractor as a single phase.      A small amount of solvent, preferably a hydrocarbon is added to the mixture causing the resulting distillate to separate into two phases, one phase containing the desired product, the other containing primarily water.      The process described is applicable to both batch and continuous operation and is not constrained by the difficulty of separating closely boiling azeotropes and results in substantially higher production rates than achieved by current processes.
Patent CA-2307805-A1 (CA)
Inventor: WILLIAMS DAVID
IPC: A61K38/55
Filed: 1998-10-30
Abstract: L'invention a trait à l'établissement d'un relevé topologique des sites actifs d'enzymes qui catalysent une modification covalente comprenant, mais non limitée à une phosphorylation, une acylation et une déphosphorylation dans lesquelles est modifié un résidu fixe (connu sous le nom de résidu catalytique) tel qu'un résidu de tyrosine, de sérine, de thréonine, d'histidine, d'acide aspartique ou tout autre résidu contenant une chaîne latérale appropriée. Le relevé topologique de protéine kinases est donné en exemple. Le procédé de l'invention comporte un niveau supplémentaire de complexité qui surpasse celui de banques à auto-déconvolution décrites dans WO97/42216. Cela implique la formation d'une banque constituée de banques plus petites (appelées sous-ensembles) dans lesquelles un résidu fixe est déplacé par étapes à travers la séquence d'acides aminés ou d'autres groupes (tels que des peptidomimétiques). A l'aide de 5 sous-ensembles de banques de peptides de 5 acides aminés, on obtient le relevé topographique d'une séquence de 9 acides aminés. En général, on peut mettre en oeuvre le procédé à l'aide de n sous-ensembles de peptides n-mères de manière à produire des données topographiques pour les résidus situés entre -(n-1) et +(n-1) de chaque côté du site actif. Ainsi, en général, la longueur de la séquence faisant l'objet du relevé topographique est de (2n)-1. Dans cette invention, il n'est pas nécessaire de séparer des séquences modifiées de séquences non modifiées en raison de la nature d'auto-déconvolution de la banque. Le criblage d'échantillons produit une série d'occurrences dont les motifs révèlent les séquences uniques dans chaque puits. Cela permet de déterminer un motif de des préférences de substrat pour toute enzyme. Les séquences uniques obtenues au moyen de l'invention peuvent être utilisées pour produire des substrats utiles pour des titrages de haut rendement, et fournir des informations détaillées concernant le site actif afin de contribuer à une conception rationnelle de médicaments. L'invention peut également être utilisée comme banque d'inhibiteurs à tester contre des enzymes modificatrices connues pour lesquelles un substrat connu existe et peut être organisé selon un format de titrage.

Title: Method and system for detecting dislodgment of an implanted right atrial endocardial lead using a sensing period derived from a ventricular lead
Inventor: KIM JAEHO
IPC: A61N1/37
Filed: 1999-06-11
Abstract: A system, and method are provided for detecting dislodgment of a right atrial endocardial lead (35) implanted within a heart right atrium wherein the lead includes an electrode. Heart activity of the right ventricle of the heart, and heart activity with the endocardial lead electrode are sensed during a time period. The sensed heart activity is stored in memory (90). The stored heart activity is analyzed to establish a first time window from the sensed ventricle activity, a second time window spaced from, and preceding the first time window. The heart activity sensed with the endocardial lead electrode during the first time window is then compared to the heart activity sensed with the endocardial lead electrode during the second time window. In another embodiment, whenever heart activity is sensed with the atrial endocardial lead during the first time period, the atrial endocardial lead is considered dislodged.
