Patent number: 6815462Abstract: The invention relates to new carbohydrate derivatives of paclitaxel and docetaxel with increased solubility in water as compared to the parent compounds, paclitaxel and docetaxel These derivatives are produced from naturally occurring precursor molecules which upon hydrolysis yield these natural precursors and the original paclitaxel and docetaxel molecules. The present invention also relates to the composition and the use of such derivatives for cancer therapy. These derivatives may also be used in antifungal or antiviral therapy.Type: GrantFiled: January 9, 2003Date of Patent: November 9, 2004Assignee: Bioxel Pharma Inc.Inventor: Michel Pagé

Patent number: 6688312Abstract: The present invention relates to a new cosmetic method for removing hemorrhoids. The method comprises sequentially the steps of 1) Isolating a hemorrhoidal mass from a patient with a curved forceps applied at the perianal skin outside the mucocutaneous junction, and eversion of the internal and external hemorrhoidal mass. 2) Application of another curved forceps at the base of the internal hemorrhoid, and suturing under the forceps with 20 catgut (securing hemostasis), then amputation of the internal hemorrhoid with a knife. 3) Leaving the first forceps in place, application of the second forceps at the base of the external hemorrhoid, suturing as above, amputation of the external hemorrhoid, and removal of the forceps. 4) This procedure is repeated for the remaining hemorrhoids.Type: GrantFiled: May 23, 2002Date of Patent: February 10, 2004Inventor: Sarkis Yeretsian

Patent number: 6670524Abstract: The present invention relates to a novel method for the prediction of fiber length and the selection of superior trees using genetic marker loci. The method comprises comparing genotypic survey data to phenotypic data collected from the same trees used to create the genotypic survey and identifying particular genetic marker loci or quantitative trait loci (QTL's) that are associated with fiber length. The method allows superior trees to be identified, from both plantations and natural populations, and selected for in tree improvement breeding programs by genotyping with identified genetic marker loci.Type: GrantFiled: January 31, 2000Date of Patent: December 30, 2003Assignee: Pulp and Paper Research Institute of CanadaInventors: Simon Potter, Paul A. Watson

Patent number: 6596508Abstract: The present invention relates to an expression system for the expression of desired gene. The expression system of the present invention comprises a cyclic AMP sensitive promoter operably linked to a DNA sequence comprising the coding region of the desired gene. The expression system of the present invention has the advantage of having a low basal level and an high induced level.Type: GrantFiled: March 19, 1999Date of Patent: July 22, 2003Assignee: National Research Council of CanadaInventor: Yves Durocher

Patent number: 6476194Abstract: The present invention relates to methods of treating and diagnosing protein trafficking disorders and controlling secretory protein production. The present invention also relates to methods for folding unfolded proteins, especially in heterelogous expression systems. The methods comprise exposing an unfolded protein to a biological preparation comprising ERp57 in combination with calnexin or calreticulin under conditions to permit folding of the unfolded protein.Type: GrantFiled: June 29, 1999Date of Patent: November 5, 2002Assignee: National Research Council of CanadaInventors: Daniel C. Tessier, Andrë Zapun, John J. M. Bergeron, David Y. Thomas
-
Patent number: 6420548Abstract: The present invention relates to a method of regulating the transcription of transgene in genetically-modified organisms. More specifically, the invention relates to the use of expression vectors harboring the coding sequence of a gene of interest under the transcriptional control of promoting sequences for which activity is regulated by the presence of nitrogen.Type: GrantFiled: October 3, 2000Date of Patent: July 16, 2002Assignee: Medicago Inc.Inventors: Louis-Philippe Vézina, Marc-André D'Aoust

Patent number: 6339071Abstract: The present invention relates to antisense oligonucleotides directed to the human cyclin E gene for inhibiting its expression, and to a method for inhibiting cellular proliferation. The antisense oligonucleotides of the present invention have been designed from the 5′ and 3′-untranslated region of the cyclin E gene for inhibiting the expression of the cyclin E gene. These antisense oligonucleotides can be used for research purposes, diagnostics and treatment of disease. Methods for specifically modulating cyclin E expression in cells and tissues using the antisense oligonucleotides are disclosed. Methods for diagnosis, detection and treatment of pathologies involving cyclin E gene are disclosed.Type: GrantFiled: January 20, 2000Date of Patent: January 15, 2002Assignee: Angiogène Inc.Inventor: Luc Lévesque

Patent number: 6248683Abstract: The present invention is concerned a process for the regeneration of the spent silica gel used in chromatography and for any other kind of silica. The process comprises 5 main steps, namely: washing with an extractant of organic compounds and removing volatile organic materials remaining thereafter; oxidation to oxidize organic compounds remaining and, preferably, bleach the material; washing with an acid to remove soluble inorganic matter; heating to dry the material and combust any remaining organic compounds present; and recovering the regenerated material. Various optional steps can be added to the process.Type: GrantFiled: April 7, 1999Date of Patent: June 19, 2001Assignee: Silicycle Inc.Inventors: Luc Fortier, Simon Côté, Hugo St-Laurent, Simon Bernier, André Couture
