20020034753, Mar 21, 2002

Filed:

May 14, 2001

Appl. No.:

09/863527

Inventors:

Li Yang - San Diego CA, US
Xun Wang - San Diego CA, US
Tong Zhu - San Diego CA, US
Liang Shi - San Diego CA, US

International Classification:

C12Q001/68
C12Q001/70

US Classification:

435/006000, 435/005000

Abstract:

Currently, three technologies are utilized for analysis of gene expression: hybridization-based technologies, PCR-based technologies, and sequence-based technologies. The present invention provides a method for analyzing the presence and/or amount of a specific nucleic acid using a solid support and a capture probe complementary to a region of a target nucleic acid, and polymerizing a labeled extension complementary to the target nucleic acid. The invention provides a method of analysis of all types of nucleic acids, and can be used to study multiple genes in a single assay using different capture probes conjugated to different class of microspheres that can be mixed in any desired combination.

13/978333

Inventors:

New Jersey Institute of Technology - , US
Li Yang - San Diego CA, US

International Classification:

F01M 11/03

US Classification:

208179, 21016708, 21032189

Abstract:

An oil circulation system and method for continuously purifying engine oil including an engine operably connected to an oil reservoir, wherein at least one stream of oil is conveyed from the oil reservoir to the engine via a conduit, and circulated through the engine and conduit via engine operating pressure and/or one or more pumps, and at least one membrane unit positioned in a path of the oil stream such that oil containing dissolved/emulsified droplets of water is fed continuously through the membrane unit. A cross flow hollow fiber module adapted to be positioned in a system for continuously purifying engine oil, the hollow fiber module having a central feed distributor tube, hollow fiber membranes positioned around the central feed distributor tube, end caps with ports for receiving and emitting a flow of sweep air, and optionally a shell casing, wherein the central feed distributor tube includes openings sized and positioned to allow oil to flowing into the feed distributor tube to flow out radially.

US Classification:

426310

Abstract:

Fresh produce is preserved by coating the exterior surface of the produce with a coating composition comprising an aqueous solution of from about 0. 5 to about 4 percent by weight of a cellulose derivative, preferably sodium carboxymethylcellulose, from about 0. 05 to about 0. 5 percent by weight of konjac, and from about 0. 03 to about 0. 1 percent by weight of surfactant, preferably dioctyl sodium sulfosuccinate. Optional constituents include antimicrobials, plasticizers and antifoaming agents. The coating composition is effective to control respiratory exchange, i. e. , the passage of gases, particularly oxygen, ethylene, carbon dioxide and water vapor, into and out of the produce, thereby to control maturation and ripening of the produce.

US Classification:

426310

Abstract:

Fresh produce is preserved by coating the exterior surface of the produce with a coating composition comprising an aqueous solution of from about 1 to about 20 percent by weight of substantially hydrolyzed cold water insoluble polyvinyl alcohol, about 0. 1 to about 10 percent by weight of low molecular weight cold water soluble starch, and about 0. 03 to about 5 percent by weight of surfactant. Optional constituents include antimicrobials and plasticizers. The coating composition is effective to control respiratory exchange, i. e. , the passage of gases, particularly oxygen, ethylene and carbon dioxide, into and out of the produce, thereby to control maturation and ripening of the produce.
