Title: Dopaminergic neurons and proliferation-competent precursor cells for treating parkinson's disease
Inventor: CARPENTER MELISSA K
IPC: A61K35/12
Filed: 2002-06-20
Abstract: This disclosure provides improved methods for obtaining populations of neural progenitor cells and differentiated neurons from pluripotent stem cells. The technology can be used to produce progenitors that proliferate through at least 40 doublings, while maintaining the ability to differentiate into a variety of different neural phenotypes. Cell populations have been obtained that contain a high proportion of cells staining for tyrosine hydroxylase, which is a feature of dopaminergic neurons. The neural progenitors and terminally differentiated neurons of this invention can be generated in large quantities for use in drug screening and the treatment of clinically important neurological disorders, such as Parkinson's disease.

Patent CA-2453460-A1 (CA)
Title: Method of forming a threaded fastener with dual reinforcing leads
Inventor: FISCHER ROBERT B
IPC: F16B35/00
Filed: 2003-12-17
Abstract: A new and improved threaded fastener comprises a first, primary thread lead, and a pair of second, auxiliary thread leads alternatively interposed between successive threads of the first, primary thread lead. The threaded fastener further comprises a pointed tip portion for initiating driving insertion of the threaded fastener into an underlying workpiece, and that portion of the dual reinforcing lead, which has previously been interposed between the tip portion and the primary thread lead, or between the first and second successive threads of the first primary thread lead, has been removed. In this manner, a circumferentially extending space has effectively been created for permitting chips or debris, normally generated during the self-tapping of the threaded fastener into a bore previously pre-drilled within the underlying workpiece, to be temporarily accumulated within such circumferential space whereby such chips or debris can subsequently be automatically discharged from such space into the depths of the pre-drilled bore as the threaded insertion of the threaded fastener into the predrilled bore of the workpiece proceeds. This structure reduces torque insertion levels and permits enhanced depth penetration of the threaded fastener into the workpiece.

Title: Injectable compositions for the controlled delivery of pharmacologically active compound
Inventor: MURTHY YERRAMILLI V S N
IPC: A61P31/04
Filed: 2002-10-18
Abstract: The present invention provides compositions and methods for extending the release times and lowering the toxicity of pharmacologically active compound s. The compounds comprise a salt of the pharmacologically active compound with a lipophilic counterion and a pharmaceutically acceptable water soluble solven t combined together to form an injectable composition. The lipophilic counteri on may be a saturated or unsaturated C8-C22 fatty acid, and preferably may be a saturated or unsaturated C10-C18 fatty acid. When injected into a mammal, at least a portion of the composition precipitates and releases the active compound over time. Thus, the composition forms a slowly releasing drug depo t of the active compound in the mammal. Therefore, the present invention enabl es one to provide a controlled dose administration of the active compound for a periods of up to 15 days or even longer. Many compounds can be administered according to the present invention including, but not limited to, tilmicosin , oxytetracycline, metoprolol, fluoxetine, roxithromycin, and turbinafine.</SD OAB>

Patent CA-2464720-A1 (CA)
Inventor: PETTERSON TOR H
IPC: B65D83/44
Filed: 2002-10-30
Abstract: A valve assembly (20) can automatically dispense aerosol content from an aerosol container (22) at predetermined intervals without the use of electric power. A diaphragm (58) at least partially defines an accumulation chamber (80) that receives aerosol content from the can (22) during an accumulation phase. Once the internal pressure of the accumulation chamber (80) reaches a predetermined threshold, the diaphragm (58) moves, carrying with it a leg (62) so as to unseal a valve stem (68), and thereby initiate a spray burst. The diaphragm (58) assumes its original position when the pressure within the accumulation chamber (80) falls below a threshold pressure. A barrier prevents the aerosol container (22) from resupplying the accumulation chamber (80) at a high rate during the spray phase, preferably due to a textured interface between the barrier and a passageway in which it is housed.

Abstract: Inhibitors of mismatch repair can be used to generate hypermutable cells and organisms. By inhibiting this process in cells, new cell lines and varieties with novel and useful properties can be prepared more efficiently than by relying on the natural rate of homologous recombination. These methods are useful for generating targeted loci that can alter the expression profiles of target genes as well as tag exons of gene with a reporter marker to facilitate the monitoring of a given gene product when the host is grown under different conditions or exposed to biological and chemical entities.

Abstract: The invention relates to a support module with an impervious closure for vehicle doors. The inventive module essentially comprises a flexible laminar element (2) which provides the impervious closure between the moist zone and the dry zone of the door (1) and which is also intended to facilitate the assembly of each of the components. The support capacity of the aforementioned flexible laminar element is sufficient such that the different components of the door can first be mounted on said element prior to the installation of the assembly in the door in a single operation. However, the resistance capacity and the structural capacity of the door are provided by the reinforcing and stiffening members of same and not by the flexible laminar element, thereby simplifying and reducing the cost of the laminar element and the assembly.
