Title: Methylation of plasmid vectors
Inventor: YEW NELSON S
IPC: C12N15/88
Filed: 1999-09-09
Abstract: Unmethylated plasmid DNA vectors are a major contributor to the inflammatory  response associated with gene delivery. Results of clinical studies where CF  subjects were subjected to either aerosolized liposomes alone or cationic lipid:DNA complexes indicated that bacterial derived plasmid DNA may be inflammatory. Additionally, unmethylated CpG dinucleotides have been shown t o be immunostimulatory and are present at a much higher frequency in bacterial ly- derived plasmid DNA compared to vertebrate DNA. The invention provides for methods of modulating the immunostimulatory response to gene delivery by modifying the plasmid delivered to the cell. The plasmid is modified to redu ce or eliminate the immunostimulatory response in order to preserve the efficac y of gene transfer but reduce the associated toxicity. In a preferred embodiment, the invention provides for a method of reducing inflammatory response to gene delivery by methylating CpG motifs of the plasmid vector and/or removing CpG motifs of the plasmid vector.
Patent CA-2344385-A1 (CA)
Inventor: MILNER PETER JAMES
IPC: F21S11/00
Filed: 1999-09-20
Abstract: An optical component (11) comprises two transparent flat bodies (12, 13) each having grooves (16) or other surface features on one of its faces (15) which interpenetrate when the two bodies (12, 13) are placed face-to-face. The shapes of the grooves (16) or other surfaces features are such that they touch in some places (20, 22, 23) and are spaced from one another in others (18, 19) to form voids (24) within the composite body (11) so formed. These cavities (24) assist in determining total internal reflection of incident light at certain angles. Composites bodies formed from two face-to-face optical components may be used as daylighting screens both to direct light towards an object such as the interior of a building (through an opening) or to screen light from it by diverting it away therefrom.

IPC: C12Q1/68
Filed: 1999-10-28
Abstract: A diagnostic assay for detecting a negative-strand RNA virus in a sample and a genetically engineered cell for use in the assay are disclosed. The cell expresses a heterologous DNA-dependent RNA polymerase that synthesizes a minigenome or miniantigenome of the RNA virus from a cDNA template present in the cell. The cell also expresses the nucleocapsid proteins of the negative-strand virus that are necessary for replication of the minigenome or miniantigenome. Infection of the cell by the negative-strand virus results in expression of a reporter gene product encoded by the miniantigenome.

Title: Cross-head die
Inventor: PENG HONG
IPC: B29C48/06
Filed: 2000-02-24
Abstract: A cross-head die (20) which is comprised of a die body (25) with a flow chamber (38), a plurality of die cavities (30), die elements (48) within the die cavities (30), communication between the die cavities (30) and the flow chamber (38), a means for individual flow adjustment to each die cavity (30), and a means for axial motion of the filamentary members (14) through the die elements (48). The single flow chamber (38) communicates to a plurality of die cavities (30) through individual radial flow ports (40). The flow chamber (38) is open at one end (27) and closed (28) at the other except for a cleaning hole (23). Within each of the radial flow ports (40) resides a device for adjusting flow restriction. Within each die cavity (30) is a cylindrical die piston (32). A gap created between the die piston (32) and the die cavity (30) defines a path for resin flow. The resin flow path is tapered to a point at which the filamentary member (14) exits from a smaller cylindrical hole (34) through the center of the die piston (32). The resin is deposited on the filamentary member (14) as it moves through the die piston (32) to produce a composite matrix strand.

Title: Pressure-controlled three-way valve device for transport vehicle tires and remote pressure control method
Inventor: VENICA NESTOR J
IPC: B60C23/00
Filed: 2001-11-01
Abstract: A remote pressure-controlled three-way valve device (11) for use as a tire valve in a tire inflation control system in transport vehicles, without needing additional control lines. The device comprises a plunger (21) axially traversed by an inlet passage (17A) normally closed by an inlet valve urged by a spring (23).  The outer side wall of the plunger has a recess (35) in which a o-ring (37) extends that, in addition to abutting against the steps (41) of the recess to limit the plunger stroke, keeps an outlet passage (15B) closed to a venting port (17B) formed in the side wall of the body (13) of the device. The plunger includes an o--ring (43) preventing short-circuits between the inlet passage and the vent port and a spring (47) for counteracting friction between the o-ring and the inner wall of the device. Filters (51A; 51C) are arranged in respective ports (17A, 17C) connectable to the input air-pressure supply and the tire inner tube and furthermore provide fixed seats for the springs to bear on. The plunger may dwell in a stable intermediate position that opens the outlet or deflation passage is controlled by sending an air pressure through the inlet port at 50% of the normal pressure.

Abstract: An optical disk device is capable of preventing a signal from being incorrectly recorded or erased on another data plane different from a data plane in a recording operation on a disk having plural layers of data plane. A focus monitor monitors an increase of a focus error signal.      A reflected light quantity monitor may monitor a drop of reflected light quantity. A move from a layer of a data plane during recording may be detected. Depending on these results, a light intensity controller reduces an intensity of a light beam to a reproducing level. The light intensity controller once reduces the intensity to a reproducing level when recording signals in plural layers of data plane.      After moving to the layer followed by the focus of the light beam, the intensity of the light beam is raised again to the recording level.

Title: Comfort support system brassiere
Inventor: WAITZ SANDRA ANN
IPC: A41C3/00
Filed: 2001-11-16
Abstract: There is provided a brassiere made of a stretchable material for comfort. Each breast cup has a breast receiving portion with an inner layer and an outer layer, and a support panel portion with the inner and outer layers and a breast supporting panel between the inner and outer layers. The breast supporting panel is substantially inelastic in all directions and, preferably, forms an arcuate edge for supporting the breast. Thus, the entire brassiere stretches and moves with the wearer, while each non-elastic breast supporting panel provides the desired breast support. The bottom edge of the breast supporting panel is spaced from the bottom edge of the brassiere. Decreasing the length of the breast supporting panel so that its bottom edge does not contact the bottom edge of the brassiere allows the bottom periphery of the brassiere to have additional flex that improves the overall comfort of the brassiere. Preferably, the bottom edge of the brassiere is turned to form the waistband of the brassiere
