Abstract: A method and an accompanied apparatus for aligning an electron emitter with an extractor hole of a microcolumn. Four V-grooves (240), defined together with the window (220) for forming the membrane and having bottoms situated on two axis are microfabricated on a chip. The axis intersect at a right angle and defines a center point for the extractor hole (230). The V-grooves are then used as references to align the electron emitter with the extractor hole, one axis at a time. The emitter is precisely aligned to the extractor hole because the extractor hole was formed with reference to the V-grooves. The thickness of the chip is used as the spacing reference between the emitter and the extractor.

Patent CA-2328505-A1 (CA)
Inventor: FINNEY HELENE MARGARET
IPC: C07K14/73
Filed: 1999-05-06
Abstract: DNA is described which codes for chimeric receptors which contain two or mor e independent polypeptide chains each of which contains an extra cellular liga nd association domain attached to a signalling domain through a transmembrane a nd optionally one or more spacer domains. Each polypeptide chain can be express ed in an effector cell and will remain largely unassociated with the other(s) i n the absence of ligand. The presence of ligand induces a stable interaction between the ligand association domains of each chain and facilitates interaction between the intracellular domains leading to a signalling event and activation of the cell. The activated cell may be of use in medicine for  example in the treatment of diseases such as cancer.

Abstract: A method and system of selling healthcare services to a patient. A number of healthcare service providers are contracted and registered with a healthcare marketplace operator. Information regarding the healthcare service providers is stored in a database. A prospective patient is provided with a case statement template having one or more areas to specify clinical and non-clinical requirements of the patient. The patient uses the template to provide case statement information to the marketplace operator. In many instances, the case statement template is completed with the assistance of the patient's primary physician. The case statement information is received and processed by the marketplace operator. The marketplace operator generates a case statement from the case statement information and the case statement is made available or distributed to contracting healthcare providers. In general, the healthcare providers set a number of screening factors so that they receive case statements related to the type of medical procedures the healthcare service providers wish to perform. Interested healthcare providers then prepare proposals or responses to the patient's case statement. The responses received form the healthcare service providers are then delivered to the prospective patient. The prospective patient then reviews the responses from the healthcare providers. The responses may include clinical quality indicators such as mortality rate, physician licensing, physician and medical staff experience, malpractice claims, available medical equipment, and other relevant information. The patient may secure the services of one of the contracting service providers by submitting a deposit.

Patent CA-2345157-A1 (CA)
Inventor: HELLER ADAM
IPC: C12Q1/68
Filed: 1999-11-19
Abstract: The invention relates to a method for the electrochemical detection of sequence-specific nucleic acid oligomer hybridization events. To this end single DNA/RNA/PNA oligomer strands which at one end are covalently joined to a support surface and at the other, free end, covalently linked to a redox pair, are used as hybridization matrix (probe). As a result of treatment with the olignucleotide solution (target) to be examined, the electric communication between the conductive support surface and the redox pair bridged by the single-strand oligonucleotide, which communication initially is either absent or very weak, is modified. In case of hybridization, electric communication between the surface support and the redox pair, which is now bridged by a hybridized double-strand oligonucleotide, is increased. This permits the detection of a hybridization event by electrochemical methods such as cyclic voltametry, amperometry or conductivity measurement.
