Patent CA-2314915-A1 (CA)
Inventor: SAVARD PIERRE
IPC: A61K33/24
Filed: 2000-08-03
Abstract: The present invention relates to the use of peroxovanadium compounds in the prevention of angiogenesis, restenosis and the production of endothelins, and as immunomodulators. Peroxovanadium compounds are preferred since they are more potent, and less toxic, than their "oxo" counterparts. Anti-angiogenic activity was verified in vitro against human umbilical vascular endothelial cells (HUVECs) as well as ex ovo using the chicken chorioallantoic assay membrane and in the rat aortic ring model and a Matrigel assay in vivo. Peroxovanadium compounds also decrease basal levels and inhibit the increase in plasma endothelins occurring following insulin induction in rats.  It is proposed that peroxovanadium compounds are therapeutically-active anti-angiogenics and useful in preventing vascular restenosis by acting, inter alia, by inhibiting one or several protein tyrosine phosphatases (PTPs) involved in the proliferation, differentiation and migration of cells or the secretion of peptides (such endothelins and immunomodulators), or both.

Abstract: One embodiment of the present invention improves the vis-ual use of urine test strips and reagent pads by providing a single color from a reference color spectrum directly on the colorimetric strip and adjacent to the reagent area to allow easy comparison. After application of a fluid to be tested to a reagent area on the colorimetric strip, a technician is able to easily compare the color in the reagent area to the refer-ence color area(s) to determine the presence or absence of, for example, glucose, in the fluid placing at least one ref-erence color immediately next to the reagent area markedly im-proves technician's accuracy in comparing and analyzing the reagent area against the reference color(s). The present in-vention allows a technician to easily and quickly compare a reagent area color to more than one reference area to deter-mine the actual numerical value of, for example, the pH in the tested fluid.

Title: Device and method for generating and distributing coded symbols in cdma communication system
Inventor: KANG HEE WON
IPC: H04L27/26
Filed: 1999-05-31
Abstract: A device and method for generating and distributing convolutional codes such that performance degradation due to a bad link environment may be minimized during channel decoding in a CDMA communication system. The convolutional encoder encodes transmission data at a coding rate of R=1/6 and can be used for a channel encoder. Such a channel encoder can be used in both a DS-CDMA communication system and a multicarrier CDMA communication system. When the channel encoder is used in the multicarrier CDMA communication system, the symbols outputted from multiple constituent encoders for the channel encoder are distributed to multiple carrier channels according to a predetermined rule, and the constituent encoders for the channel encoder can minimize the performance degradation of the overall channel encoder even though an output of a particular constituent encoder is completely off at the transmission channel.
