Title: Peptide for stimulation of cytotoxic t lymphocytes specific for hepatitis c virus
Inventor: BERZOFSKY JAY A
IPC: A61K39/29
Filed: 1993-06-10
Abstract: The cytotoxic T cell response to the protein encoded by the NS5 region of hepatitis C virus was determined using 28 peptides from NS5 which were selected by an amphipathicity algorithm as candidates for T cell epitopes. In BALB/c mice, a single relatively conserved epitope represented by a 16-residue synthetic peptide was presented by D d class I major histocompatibility complex (MHC) molecules to conventional CD4-CD8 + CTL. An exemplary peptide, which represents amino acid residues 2422-2437 of the polyprotein of the Chiron HCVI isolate, had the amino acid sequence MSYSWTGALVTPCAAE {SEQ ID NO: 1}. A CTL line specific for this peptide recognized the two known natural variants of this NS5 sequence, each with conservative substitutions. Thus, CTL can recognize the product of the HCV NS5 gene, the probable RNA polymerase, in association with class I MHC molecules on model target cells and may recognize the same epitope on hepatocytes or any other cells infected with the virus.

Title: Spin valve magnetoresistive sensor with free layer exchange biasing, process for making the sensor, and magnetic recording system using the sensor
Inventor: FONTANA ROBERT EDWARD
IPC: G11C11/15
Filed: 1995-05-09
Abstract: An improved spin valve (SV) magnetoresistive element has its free ferromagnetic layer in the form of a central active region with defined edges and end regions that are contiguous with and abut the edges of the central active region. A layer of antiferromagnetic material, preferably a nickel-manganese (Ni-Mn) alloy, is formed on and in contact with the ferromagnetic material in the end regions for exchange coupling with the end regions to provide them with a longitudinal bias of their magnetizations. The pinned ferromagnetic layer in the SV element is pinned by exchange coupling with a different layer of antiferromagnetic material, preferably an iron-manganese (Fe-Mn) alloy. This material has a substantially different Neel temperature from that of the antiferromagnetic material on the end regions. The process for making the SV element includes heating to different predetermined temperatures in the presence of an applied magnetic field to orient the magnetizations of the free and pinned layers in the proper direction. The SV element may be used as a sensor for reading data in magnetic recording systems.
Patent CA-2149696-A1 (CA)
Inventor: RITT PETER MICHAEL
IPC: G03G13/22
Filed: 1995-05-18
Abstract: A method of electrophotographically manufacturing a luminescent screen assembly on a photoreceptor disposed on an interior surface of a faceplate panel for a color CRT includes the steps of: charging the photoreceptor to establish a substantially uniform electrostatic voltage thereon; positioning the panel on an exposure device having a light source therein; exposing selected areas of the photoreceptor to visible light from the light source to affect the voltage thereon, without affecting the voltage on the unexposed area of the photoreceptor, and depositing a triboelectrically charged, first color-emitting phosphor onto the selected areas of the photoreceptor. The charging, positioning, exposing and depositing steps are repeated for a second and a thirdtriboelectritcally charged, color-emitting phosphor. The present method is an improvement over prior methods because, after each of the phosphor deposition and panel recharging steps, the light source is offset in the exposure device by an amount determined by the voltage difference between the photoreceptor and the phosphor, or phosphors, previously deposited onto the panel, thereby counteracting the repulsive effect of the previously deposited phosphor and minimizing the misregister of subsequently deposited phosphors.

Patent CA-2164262-A1 (CA)
Title: Biostable porous material comprising composite biopolymers
Inventor: DOILLON CHARLES J
IPC: A61L27/48
Filed: 1995-12-01
Abstract: Biomaterials like collagen can be designed for use as scaffolds for connective tissue reconstruction. It is known that proteins conjugated with PEGs exhibit a  decrease  in  their biodegradation  rate  and their immunogenicity. Different concentrations and molecular weights of PEGs (PEG-750 and PEG-5000) were conjugated by chemical or irradiation means to collagen materials (films or sponges)  which were then investigated by physicochemical assays, collagenase assay,  fibroblast cell    culture    and    subcutaneous    implantation. PEG-conjugation delayed the degradation by collagenase and  preserved  a  normal  fibroblasts  morphology  and confluency in culture. In vivo, the porous structure of non-modified sponges was collapsed by day 15 with few observable fibroblasts between the collagen fibers. In PEG-modified collagen sponges,  the porous  structure remained stable for at least 30 days. Cell infiltration was particularly enhanced in PEG-750-conjugated collagen sponges. In conclusion, PEGs conjugated onto collagen sponges   stabilize  the  porous   structure  without deactivating the biological properties of  collagen. These porous composite materials could advantageously function as a scaffold to organize tissue ingrowth. Therefore, the present invention relates to a porous biomaterial whose porosity is stabilized by conjugation to PEG-derivatives.  Biopolymers other than collagen may be used in the making of such composite materials.

Title: Focused acoustic wave fiber optic reflection modulator
Inventor: SMITH RONALD H
IPC: G02B6/34
Filed: 1996-01-08
Abstract: An improved optical fiber modulator producing a focused acoustic wave propagating from an acoustic transducer surrounding an optical fiber having an in-fiber reflection grating changes the core refractive index in proportion to the induced strain at the core when the focused acoustic wave arrives at the optical fiber core, and focused acoustic waves can also modulate optical carrier phase in a length of optical fiber which may lie in an arm of an interferometer. In a preferred embodiment, the index change shifts the reflection spectrum of an in-fiber grating located in the portion of optical fiber core on which the focused acoustic wave is centered with the reflection spectrum shift producing a change in the grating reflectivity for a narrow bandwidth optical signal on a skirt of the grating spectrum. Electronic multiplexing means may be used to both transmit and receive signal information on a single optical carrier signal, and a plurality of acoustic wave modulators may be placed along a single optical fiber, simultaneously modulating a plurality of optical signals each having an optical frequency matched to one of the modulator gratings. Acoustic wave modulators may be tuned to a range of optical carrier frequencies using thermal or mechanical strain control, and a series of tuned modulators lined up along an optical fiber accessed through an optical circulator will reflect and modulate selected signals which are then forwarded back through the circulator onto a transmission line optical fiber.
