Abstract:
The invention provides methods for modulating a cellular process by contacting a cell in culture with a cell process-modifying molecule attached to a translocating polypeptide. For example, in one embodiment, a cell in culture is transfected with a target gene by contacting the cell in culture with a polynucleotide (that contains the target gene) attached to a translocating polypeptide. In another embodiment, expression of a target gene product in a cell in culture that contains a target gene under control of one or more regulatory elements is modulated by contacting the cell in culture with one or more regulatory agents attached to a translocating polypeptide. The one or more regulatory agents are translocated into the cell in culture and interact therein with the one or more regulatory elements to modulate expression of the target gene product by the cell.
Abstract:
According to one embodiment, a data sources interface of a mainframe receives a transaction request from a user terminal communicating through a network. The transaction request is formatted in a web-based format. A data sources function is called to instruct a mainframe application to perform the requested transaction, and the instruction to the mainframe is formatted in the native format of the mainframe. A transaction result formatted in the native format of the mainframe is received from the mainframe application. The transaction result is modified according to the web-based format to yield a data source, and the data source is sent to the user terminal.
Abstract:
The present invention provides compositions, methods, and kits for covalently linking nucleic acid molecules. The methods include a strand invasion step, and the compositions and kits are useful for performing such methods. For example, a method of covalently linking double stranded (ds) nucleic acid molecules can include contacting a first ds nucleic acid molecule, which has a topoisomerase linked to a 3′ terminus of one end and has a single stranded 5′ overhang at the same end, with a second ds nucleic acid molecule having a blunt end, such that the 5′ overhang can hybridize to a complementary sequence of the blunt end of the second nucleic acid molecule, and the topoisomerase can covalently link the ds nucleic acid molecules. The methods are simpler and more efficient than previous methods for covalently linking nucleic acid sequences, and the compositions and kits facilitate practicing the methods, including methods of directionally linking two or more ds nucleic acid molecules.
Abstract:
A microwave oven and a refrigerator are combined in a single cabinet and share line power supplied to the cabinet. Door interlocks and a manually settable time are provided for disconnecting electrical supply to the compressor of the refrigerator during operation of the magnetron of the microwave oven. The circuitry provided ensures that electrical supply is reconnected to the compressor upon expiration of the timer setting, even if the door of the oven is incidentally left open after use.
Abstract:
An aqueous solution is applied to water insoluble solid particles when flowing from one location to another location to improve the flow characteristics of the particles while inhibiting caking characteristics of the particles. The aqueous solution comprises a water soluble polymer derived from cellulose.
Abstract:
A method of generating a double stranded (ds) recombinant nucleic acid molecule covalently linked in both strands by contacting two or more ds nucleotide sequences with a topoisomerase under conditions such that both termini of at least one end of a first ds nucleotide sequence are covalently linked by the topoisomerase to both termini of at least one end of a second ds nucleotide sequence is provided. Also provided is a method for generating a ds recombinant nucleic acid molecule covalently linked in one strand, by contacting two or more ds nucleotide sequences with a type IA topoisomerase under conditions such that one strand, but not both strands, of one or both ends of a first ds nucleotide sequence are covalently linked by the topoisomerase. Compositions for performing such methods, and compositions generated from such methods also are provided, as are kits containing components useful for conveniently practicing the methods.
Abstract:
The present invention provides a method and composition for on-line treatment of furnace walls that are subject to deposition of highly reflective ash. The method involves exposing the walls to a darkening agent, or a combination of a darkening agent and a fluxing agent. The darkening agent, or the combined darkening agent and fluxing agent, may be mixed with the coal before it enters the boiler. Preferably, the appropriate walls of the boiler are treated directly with the darkening agent. A preferred embodiment involves direct application of the darkening agent to the water wall.
Abstract:
A microwave oven and a refrigerator are combined into a single cabinet housing a shared power supply with an electrical supply disconnect for the magnetron of the oven during a start-up power demand by the compressor of the refrigerator and for a period of time depending upon a rating of the compressor.
Abstract:
A composition of matter is used to treat particles entrained in flue gas. The composition comprises a caustic liquid to adjust the resistivity of the entrained particles. An inert particulate matter supports the caustic liquid to inhibit the chemical action of the caustic liquid until used to adjust the resistivity of the entrained particles. The entrained particles are removed from the flue gas by choosing a caustic liquid to adjust the resistivity of the entrained particles. The caustic liquid is supported on inert particulate matter to inhibit the chemical action of the caustic liquid. The supported caustic liquid is supplied to untreated flue gas at a temperature sufficient to separate the caustic liquid from the inert particulate matter. The separated caustic liquid is mixed with the entrained particles so as to coat the entrained particles. The coated particles are then passed through an electrostatic precipitator to remove them from the flue gas.
