Title: Apopain
Inventor: VAILLANCOURT JOHN P
IPC: A61P25/28
Filed: 1996-04-17
Abstract: The present invention is directed to an isolated and purified enzyme designated apopain, methods of using apopain to screen for compounds which modulate the activity of apopain, and compounds identified by the screens. A  synthetic DNA molecule encoding full length apopain is prepared from the purified enzyme. The synthetic apopain-encoding DNA is formulated so as to optimize expression in a variety of recombinant hosts. The DNA clones produce recombinant full-length apopain and derivatives thereof. Purified native apopain and recombinant apopain are useful for identifying modulators of apopain activity and hence modifiers of pathological conditions related to the pro-inflammatory or pro-apoptotic effects of apopain. Apopain antisense molecules are useful for therapeutically reducing or eliminating the pro-inflammatory or pro-apoptotic effects of apopain, whereas gene transplantation or gene therapy with apopain is useful for enhancing the pro-inflammatory or pro-apoptotic effects of apopain. These therapies are beneficial in the treatment of immune, proliferative and degenerative diseases including, but not limited to, immune deficiency syndromes (such as AIDS), autoimmune diseases, pathogenic infections, cardiovascular and neurological injury, alopecia, aging, cancer, Parkinson's disease and Alzheimer's disease.

Patent CA-2223527-A1 (CA)
Title: Linked linear amplification of nucleic acids
Inventor: WALLACE ROBERT BRUCE
IPC: C12Q1/68
Filed: 1996-06-06
Abstract: The extensive synthesis ("amplification") of a nucleic acid sequence of interest is attained through a linked series of multi-cycle primer extension reactions (LLA). The primers used in each of the primer extension reactions of the process contain non-replicable elements that halt nucleic acid synthesis and thereby prevent the synthesized molecules from serving as templates in subsequent cycles. Synthesized molecules accumulate during primer extension in a mathematically linear fashion, thereby rendering the process relatively insensitive to contaminating nucleic acids. Multiple primer sets are employed, thereby ensuring the accumulation of a large number of copies of the nucleic acid sequence of interest. The invention also provides for the detection of an amplified nucleic acid sequence of interest, as well as reagent kits for carrying out the reaction.

Title: Short channel fermi-threshold field effect transistors
Inventor: DENNEN MICHAEL WILLIAM
IPC: H01L29/10
Filed: 1996-07-19
Abstract: A Fermi-threshold field effect transistor includes spaced-apart source and drain regions which extend beyond the Fermi-tub in the depth direction and which may also extend beyond the Fermi-tub in the lateral direction. In order to compensate for the junction with the substrate, the doping density of the substrate region is raised to counteract the shared charge. Furthermore, the proximity of the source and drain regions leads to a potential leakage due to the drain field which can be compensated for by reducing the maximum tub depth compared to a low capacitance Fermi-FET and a contoured-tub Fermi-FET while still satisfying the Fermi-FET criteria. The tub depth is maintained below a maximum tub depth. Short channel effects may also be reduced by providing source and drain extension regions in the substrate, adjacent the source and drain regions and extending towards the channel regions. The source and drain extension regions are doped the same conductivity type and doping concentration as the source and drain themselves. A Fermi-FET which is particularly suitable for small linewidths is thereby provided.

Patent CA-2227673-A1 (CA)
Inventor: ROWLAND ANDY
IPC: H04B1/26
Filed: 1998-01-21
Abstract: A radio transceiver system uses a single variable local oscillator frequency source which is used in mixing both before and after a band-pass filter.  This causes a reduction in band-pass filter bandwidths.  In an all-band transceiver for PCS for example the effect of this reduced bandwidth requirement is to increase the spacing between the transmit bands and the receive bands and thereby enable a reduction in transmission noise interfering with the reception bands.
Patent CA-2228738-A1 (CA)
Title: Three step process for producing light olefins from methane and/or ethane
Inventor: MARKER TERRY L
IPC: C08F210/16
Filed: 1998-02-02
Abstract: Light olefins are produced from a hydrocarbon gas stream by a combination of steam reforming, oxygenate production, and oxygenate conversion to olefin wherein a crude methanol stream - produced in the production of oxygenates and comprising methanol, light ends, and heavier alcohols - is passed directly to the oxygenate conversion zone for the production of light olefins. Furthermore, the combination provides the synergy for increased catalyst life and reduced water treatment costs by recycling by-product water produced in the oxygenate conversion zone to provide water to the steam reforming zone. The advantage of this integration is the elimination of costly methanol separation and purification steps which result in the overall reduction in the costs of producing the light olefins.  In addition, a portion of the by-product water can be combined with a propylene stream to provide a high octane blending component for gasoline. The propylene and butylene fractions produced by the above integrated scheme are further converted to high octane ether and other high value products.
