Patent CA-2262251-A1 (CA)
Title: Construction for ultra-thin orthotic
Inventor: BROWN DENNIS N
IPC: A43B13/16
Filed: 1999-02-22
Abstract: A thin orthotic insert having a rigid rearfoot plate and a flexible forefoot cushion which are joined together without requiring a separate top cover. A connection is formed by a slot at the forward edge of the plate which receives and holds the rearward edge of the cushion layer. The rearfoot plate may be formed as a laminated structure, with forward edges of the upper and lower laminate layers being separated to form the wall portions above and below the slot. To form the slot, a spacer is inserted between the edges of the layers and then withdrawn after molding/curing. Because the need for a top cushion is eliminated, very low thicknesses can be achieved, on the order of 1.5 mm. The device is particularly advantageous for use in women's high-heeled shoes, where interior volume is extremely limited.
Patent CA-2262463-A1 (CA)
Title: New uses for compounds which reduce c-jun gene expression
Inventor: PETERSON THERESA C
IPC: A61K31/522
Filed: 1998-06-05
Abstract: In accordance with the present invention, it has been discovered that monocyte conditioned medium (MCM) obtained from patients with liver disease stimulates the proliferation of fibroblasts. Platelet derived growth factor (PDGF) has also been found to stimulate fibroproliferation of fibroblasts, and to be at least partially responsible for the fibroproliferative effect of the MCM. Further in accordance with the present invention, the effect of MCM and PDGF on the expression of c-fos and c-jun has been investigated, because c-fos and c-jun form AP-1 complexes which can stimulate genes involved in proliferation. It has recently been reported that pentoxifylline inhibits platelet derived growth factor-stimulated proliferation. Studies were conducted to determine whether pentoxifylline altered the expression of c-fos and c-jun. While PDGF was found to induce the expression of both c-fos and c-jun, pentoxifylline was found to effectively reduce the effect of PDGF-induced c-jun gene expression, without altering c-fos gene expression. These results suggest that pentoxifylline inhibits PDGF-stimulated proliferation by decreasing c-jun expression. These results further suggest a variety of diseases and/or conditions which may also be successfully treated with compounds, such as pentoxifylline, which reduce the transcription of c-jun gene.

Title: Methods and materials for optimization of electronic hybridization reactions
Inventor: TU EUGENE
IPC: C12Q1/68
Filed: 1997-08-18
Abstract: The following inventions relate to discoveries concerning the various parameters, electrolytes (buffers), and other conditions which improve or optimize the speed of DNA transport, the efficiency of DNA  hybridization reactions, and the overall hybridization specificity in microelectronic chips and devices. In particular, this invention relates to the discovery that low conductance zwitterionic buffer solutions, especially those containing the amino acid Histidine prepared at concentrations of ~50 mM and at or near the pI (isoelectric point ~pH 7.47), provide optimal conditions for both rapid electrophoretic DNA transport and efficient hybridization reactions. Hybridization efficiencies of at least a factor of 10 relative to the next best known buffer, Cysteine, are achieved. Test data demonstrate an approximately 50,000 fold increase in hybridization efficiency compared to Cysteine.

Patent CA-2277259-A1 (CA)
Inventor: SIPOS PETER
IPC: C08F210/16
Filed: 1999-07-09
Abstract: Polyethylene film having a combination of a high melt strength and a high dart impact strength is prepared from a linear low density polyethylene resin having a melt index, ("I2"), of from 0.4 to 1.5 g/10 minutes, a broad molecular weight distribution (of from 3.5 to 7) and a quasi homogeneous comonomer distribution (as evidenced by a copolymer/homopolymer ratio of from 3 to 19). The polyethylene resin is prepared in a dual reactor polymerization process. The film is especially useful for industrial and "heavy duty" packaging applications such as the manufacture of plastic packages used to contain goods for the construction, gardening and agricultural businesses. Examples of such goods include peat moss, fertilizer, soil, sand, salt, fiberglass insulation and crushed stone. The film has improved strength properties which are typically associated with those made from homogeneous (or "metallocene") polyethylene resins, yet also retains a stiff plastic "feel" which is not present in many metallocene resins. Most importantly, the plastic film of this invention may be produced at very high line speeds (i.e. improved production rates/efficiencies) in comparison to films made from prior art resins.

Patent CA-2285176-A1 (CA)
Inventor: ONOE SEIZ
IPC: H04B7/005
Filed: 1999-01-28
Abstract: To prevent interference by a mobile station conducting communication with high electric power, it is judged whether a radio base station which is the source of interference is in a macrocell or microcell. The base station adds the value of transmission power of the downstream report channel to report information. A newly established base station (C) receives a downstream frequency band, measures the reception level of the report channel, and acquires the value of transmission power. If the value of transmission power is large, the threshold value is lowered (THRb); and if the value of transmission power is small, the threshold value is raised (THRa). If the reception level (L) is below the threshold value, the channel is judged to be usable. From the reception level of the report channel and the acquired value of transmission power, the propagation loss is calculated, and if the propagation loss is below a value and the reception level is below the threshold value, the channel is judged to be usable.
