Patent number: 8318618Abstract: A mat having a highly uniform porosity distribution is produced by consolidating 15 or more layers of melt blown webs (or the like) having different orientations. Control over the porosity is provided by using webs that exhibit a narrow, unimodal distribution of fiber diameters over the bulk of its distribution, such as in the top 80%. A compliance of the mats can be chosen by selecting a number and orientation of the webs. It is thus possible to produce mats that are good candidates for vascular grafts, for example. The uniformity of the porosity within the range of 6 ?m to 30 ?m permits seeding of the vascular graft with endothelial and smooth muscle cells. The mats have the demonstrated ability to retain, and support growth of, smooth muscle cells and endothelial cells.Type: GrantFiled: May 21, 2008Date of Patent: November 27, 2012Assignee: National Research Council of CanadaInventors: Abdellah Ajji, Marie Moreno, Martin Bureau

Patent number: 8318455Abstract: An expression system for transforming E coll with a nucleic acid molecule of interest has an operator sequence of a cmt operon operatively linked to a promoter for the operator, and, a repressor sequence from a cym operon operatively linked to a promoter for the repressor. The expression system may have a nucleic acid molecule of interest, for example, a nucleic acid molecule that encodes a protein. Any type of E coll host cells may be transformed with the expression system. A method of producing a protein involves transforming an E coll host cell with the expression system having a nucleic acid molecule that codes for a protein, and, culturing the host cell in a culture medium under conditions in which the nucleic acid molecule will express the protein.Type: GrantFiled: May 14, 2008Date of Patent: November 27, 2012Inventors: Young Jun Choi, Bernard Massie, Carlos B.

Patent number: 7861655Abstract: A method and apparatus are provided for detonation of a super-compressed insensitive energetic material by cylindrical implosion followed by an axial detonation to a detonation velocity several times that of TNT and a detonation pressure in excess of ten times that of TNT. The device provides a conical metal flyer shell within which is disposed a cylindrical anvil surrounded by explosive. The anvil retains an insensitive energetic material to be compressed and detonated. A first detonation of explosive by impact of the flyer shell generates a reverberating oblique shock wave system for sample compression. Axial detonation of the compressed sample through any length of a sample is achieved following the principal of matching the axial velocity and compression time of the oblique shock wave system to the detonation velocity and induction delay time of the compressed sample. The method and apparatus are also applicable to enhancing the effect of anti-armor and anti-hard-target munitions.Type: GrantFiled: February 25, 2009Date of Patent: January 4, 2011Assignee: National Research Council of CanadaInventors: Fan Zhang, Stephen Burke Murray, Andrew J.

Patent number: 7745605Abstract: Late embryogenesis abundant (Lea) proteins accumulate in maturing seeds after many of the storage compounds have been synthesized, and they are considered relevant to maturation. We report here the molecular organization and expression of BnLea3-1, a novel Group 3 Lea gene from Brassica napus. BnLea3-1 contains a coding region of 798 bp, sharing 84.4% homology at the amino acid level with Lea76 of B. napus. Two tandem 11-mer repeats are truncated from the coding region of BnLea3-1, compared to the 13 conserved 11-mer repeats of Lea76. Substitutions of consensus residues are found at various positions within the 11-mer repeats. A 1561 bp 5? flanking promoter fragment of BnLea3-1 fused to E. coli?-glucuronidase (GUS) coding region conferred seed-specific GUS expression in stable transgenics of B. napus, tobacco and in transiently-transformed pea.Type: GrantFiled: October 9, 2007Date of Patent: June 29, 2010Assignee: National Research Council of CanadaInventors: Gopalan Selvaraj, Jun Huang, Raju Datla

Patent number: 7682815Abstract: The invention disclosure is a method of bioremediation of wastewater, particularly groundwater, by utilizing coupled anaerobic and aerobic biological treatment, more specifically, methanogenic (strictly anaerobic) and methanotrophic (strictly aerobic) microbial populations, in combination with a supply of in-situ generated water-dissolved oxygen and hydrogen. Water electrolysis is used to produce water-dissolved oxygen and hydrogen. The immediate advantage of using H2 from the electrolysis is to provide electron donors to methanogens to reductively dechlorinate the chloroaliphatics, and to reduce the water carbonates and generate methane which is used as energy and carbon source for the methanotrophic bacteria. Oxygen is used as electron acceptor by the aerobic bacteria, including the methanotrophs. The addition of an organic carbon source can be minimized or even eliminated, so as to diminish the competition between methanotrophic bacteria and heterotrophic bacteria for oxygen.Type: GrantFiled: May 25, 2005Date of Patent: March 23, 2010Assignee: National Research Council of CanadaInventors: Serge R. Guiot, Boris Tartakovsky
