Patent CA-2168878-A1 (CA)
Inventor: JEPPSSON JAN OLOF
IPC: G01N33/98
Filed: 1994-07-11
Abstract: A method for separation and quantitation of carbohydrate deficient transferrin (CDT) in order to decide a person's alcohol consumption during the most recent time. Lipoproteins are precipitated in blood serum, saturated with iron, and then the sample is centrifuged after a short storage period. The supernatant of the centrifuged mixture is then diluted with water. Subsequently the mixture is injected to an ion exchange column, when a saltgradient is used for separation of the isoforms of transferrin. A chromatogram is developed by means of HPLC and a filter for absorbance at 460 nm. Should the chromatographic profile show increased values of CDT (*,**), more than 0.8 % of total transferrin, it is a highly specific marker for heavy alcohol consumption.

Patent CA-2174966-A1 (CA)
Inventor: ERLANDER MARK G
IPC: C12Q1/6853
Filed: 1994-11-14
Abstract: An improved method for the simultaneous sequence-specific identification of mRNAs m an mRNA population allows the visualization of nearly every mRNA expressed by a tissue as a distinct band on a gel whose intensity corresponds roughly to the concentration of the mRNA. In general, the method comprises the formation of cDNA using anchor primers to fix a 3'-endpoint, producing cloned inserts from the cDNA in a vector containing a bacteriophage-specific promoter for subsequent RNA synthesis, generating linearized fragments of the cloned inserts, preparing cRNA, transcribing cDNA from the cRNA using a set of primers, and performing PCR using a 3'-primer whose sequence is derived from the vector and a set of 5'-primers that is derived from the primers used for transcription of cDNA from cRNA. The method can identify changes in expression of mRNA associated with the administration of drugs or with physiological or pathological conditions.

Filed: 1997-06-09
Abstract: Wire barriers for separating the load wiring from the hot components of an electrical distribution panel board are integrally molded from an elasticallydeformable resin with a tapered elongated member projecting axially from a base member. Attachments for securing the barriers to the backpan of the panel board include at least two hook members having hook fingers projecting laterally outward in divergent directions. In one embodiment, the hook members are formed in oppositesides of the elongated member and spaced from the base so that as the elongated member is inserted through an opening in the backpan from behind, the fingers grip the backpan and hold the barrier in place until the base is clamped between the backpan and back wall of the panel board as the backpan is installed. In another embodiment of the invention, a pair of opposing facing hook members and a third laterally facing hook member project axially from the base member. The barrier is tilted while the third hook member is inserted in the aperture in the backpan. The pair of oppositely facing hook members are then squeezed together for insertion into the opening while the barrier is rotated upright, so that they also engage the backpan when released.
