Title: Test for oxidative stress using cell suspensions
Inventor: LAMB ROBERT G
IPC: G01N33/50
Filed: 1999-06-23
Granted: 2008-05-06
Abstract: This invention provides means of measuring oxidative response of cells without recourse to preparation of cell culture. The process consists of: 1) preparing suspensions of cells from a living host in isotonic solutions, 2) preparing samples of test materials in isotonic solution containing tagged choline, 3) adding the cells suspension prepared in step 1 to the samples prepared in step 2, 4) incubating the product of step 3 with shaking for 2-90 minutes, 5) extracting and drying the lipid phase from the product of step 4, and 6) measuring the choline that has been incorporated onto PC in the product of step 5. An increase in incorporation of choline into PC in the short term indicates oxidative stress of free radical induced damage. Because the method of the invention using the cell isolates does not require the expense of cell culture with concomitant expense and possibility of cell change, it is particularly useful for clinical evaluation. Furthermore, the ability to use erythrocytes for study of cellular response to oxidative stress makes it possible to test individual responses of patient using part of the blood sample drawn routinely for laboratory use.

Abstract: Genetic constructs, transformation vectors and methods are taught for production of transgenic plants which can be selectively removed from a growing site by application of a chemical agent or physiological stress. The invention links a target gene for the trait of commercial interest to a conditionally lethal gene, which can be selectively expressed to cause plant death. By use of the genetic constructs, transformation vectors and methods of the present invention, invasion of environments and contamination of commercial non-engineered productions by transgenic plants can be avoided.  Methods are also taught for transformation of Brassica species.

Title: Method and system for ablating surfaces with partially overlapping craters having consistent curvature
Inventor: SHIMMICK JOHN KARL
IPC: G02B26/10
Filed: 2000-02-28
Granted: 2011-06-07
Abstract: This invention is a technique for laser sculpting a predetermined shape on an exposed corneal surface (6) by ablating a sequence of consistently curved craters (16a, 16b, 16c, 16d) with individual pulses of a laser beam (10). An initial laser beam energy pattern (14) is shaped by a laser beam shaping element (22) to make a consistently curved laser beam (12) energy pattern. The consistently curved laser beam (12) ablates a consistently curved crater (16) in the surface (6) with a single pulse of the laser beam (10). A computer (26) controls the position of the laser beam (10), and scans the laser beam over the surface (6) to sculpt the predetermined shape in an ablation zone (18) on the exposed surface. A sequence of partially overlapping craters (16a, 16b, 16c, 16d) are distributed over the ablation zone (18). In some embodiments diffractive optics (50) are used as a beam shaping element (33). In additional embodiments, the consistently curved crater (16) is a uniformly curved spherical crater.

IPC: B32B5/22
Filed: 2000-05-19
Granted: 2006-08-01
Abstract: A wipe product comprises a substrate and functional additive, preferably a high internal phase inverse emulsion, disposed in a discontinuous pattern on the substrate such that the pattern provides areas coated with the emulsion and areas free of the emulsion. When the product is wound into a roll, any two adjacent layers in the roll have their areas coated with functional additive offset relative to each other. This improves water-retaining characteristics and roll compressibility characteristics of the product. Preferably, the functional additive of one layer is supported by the areas free of the functional additive of the adjacent layer. During the use, upon the application of pressure to the wipe, the emulsion locally expresses water useful for cleaning. The discontinuous pattern of the emulsion provides regions of the substrate which are wetted during use and regions which may remain dry. The wetted regions transfer water to the surface to be cleaned. The dry regions then remove the water from the surface for more efficacious cleaning.
