Patent CA-2430474-A1 (CA)
Title: Protector for chemically treated wooden utility pole and surrounding environment
Inventor: DOCTER LLOYD W
IPC: E04H12/22
Filed: 2003-05-29
Abstract: The invention provides a utility pale that comprises an upper end and a lower end, with the lower end having a butt end. The butt end of the pole is encased in a substantially non-corrodible metallic cladding, that is formed from a sheet of the metal, so that the cladding protects the buried end of the pole from attack by microorganisms in the surrounding soil, when the pole end is buried. Further, the metallic cladding substantially prevents migration of any biocidal chemicals from the pole into the surrounding environment. In certain embodiments, the metallic cladding may also be connected, through a ground conductor, to form an electrical grounding means for the pole.

Patent CA-2441910-A1 (CA)
Inventor: CICCARONE VALENTINA
IPC: C12N5/02
Filed: 2002-03-27
Abstract: The present invention is directed generally to cell culture media (particularly serum free, non animal derived, and/or chemically defined media) which are useful for introducing macromolecules and compounds (e.g., nucleic acid molecules) into cells (e.g., eukaryotic cells). According to the invention, such introduction can take place in the presence of said medium.  Cells containing such introduced materials can then be cultured in the medium and the effect of the introduced materials on the cells can be measured or determined. In particular, the invention allows introduction of nucleic acid molecules (e.g., vectors) into cells (particularly eukaryotic cells) and expression of proteins encoded by the nucleic acid molecules in the cells. The invention obviates the need to change the cell culture medium each time a different procedure is performed with the cells (e.g., culturing cells vs.  transfecting cells). The invention thus provides efficient and high throughput methods to transform/transfect culture and cells avoiding the need for multiple manipulations and transfers of cells during transfection and expression studies. The invention also relates to compositions and kits useful for culturing and transforming/transfecting cells.

Title: Systeme et procede de stimulation cardiaque biventriculaire avec fusion
Inventor: HILL MICHAEL R S
IPC: A61N1/362
Filed: 2002-10-01
Abstract: La présente invention se rapporte à des systèmes de stimulation cardiaque biventriculaire et à des systèmes permettant d'améliorer la fonction cardiaque chez des patients souffrant d'insuffisance cardiaque. Ces systèmes permettent de stimuler et d'explorer les ventricules droit et gauche du coeur et plus particulièrement de stimuler l'un de ces ventricules droit et gauche après un délai auriculo-ventriculaire synchronisé à partir d'un événement auriculaire précédent et après une dépolarisation spontanée dans l'autre ventricule aux fins de l'obtention d'une stimulation cardiaque avec fusion. Il est possible de déterminer un délai auriculo-ventriculaire droit (A-RVp) et un délai auriculo-ventriculaire gauche (A-LVp) à partir d'un délai auriculo-ventriculaire droit (A-RVs) détecté intrinsèque et d'un délai auriculo-ventriculaire gauche (A-LVs) intrinsèque. Si le délai A-LVp dérivé devient sensiblement inférieur ou égal au délai A-RVs intrinsèque, alors le délai A-RVp est réduit de manière à être inférieur au délai A-LVp. La stimulation cardiaque biventriculaire du ventricule droit et du ventricule gauche est alors établie avec une synchronisation étroite par rapport aux dépolarisations intrinsèques du ventricule droit et du ventricule gauche.
