Also provided are methods of using black bear PTH and functional fragments for increasing cAMP in a bone-forming cell; reducing apoptosis in a bone-forming cell; decreasing the ratio of expression levels of Bax protein to Bcl-2 protein in a bone-forming cell; increasing the expression level of one or more of a bone matrix protein, a transcriptional activator, or a transcriptional regulator in a bone-forming cell; enhancing bone mineral density, increasing bone mass, decreasing bone loss, or reducing the incidence of bone fractures, or any combination thereof, in a subject; also provided are antibodies directed against black bear parathyroid hormone (PTH) and functional fragments thereof.
摘要:
The invention comprises modified luciferase proteins which are more resistant to inhibition by test chemicals than wild type luciferase. The modified luciferases also contain greater thermostability than wild type luciferase.
摘要:
The present invention provides compositions and methods for producing a transgenic plant that exhibits altered characteristics resulting from over expression or under expression of a novel polypeptide PtM3 or its homolog PtM4. The altered characteristics resulting from over-expression include at least one of the ability to convert axillary meristem to floral meristem; to accelerate flowering i.e., early flowering; to increase fruit production; to increase nut production; to increase seed output; to increase branching; to increase flower production; to increase fruit yield; to increase flower yield and a combination thereof. The altered characteristics resulting from suppressed expression include at least one of complete sterility; partial sterility (sterility of only one sex of a bisexual plant); reduced pollen production; decreased flowering; increased biomass and combinations thereof. Furthermore, once the transgenic plant is sterile, additional exogenous sequences may be incorporated into the sterile plant genome, resulting in other desired plant characteristics. Related promoter, gene constructs, methods, antibodies and kits are also provided.
摘要:
The present invention is directed to a single stage free radical precipitation polymerization process for producing a copolymer involving admixing a solvent, a free-radical-forming agent, (meth)acrylic acid, and at least one monomer selected from the group consisting of styrene, vinyl acetate, methylmethacrylate, butyl acrylate, methyl acrylate, acrylonitrile, and isopropylacrylamide; initiating a free-radical precipitation polymerization to form a plurality of polymer radicals; precipitating a polymer from said polymer radicals; maintaining the admixture of reactants at a temperature above the lower critical solution temperature of said admixture; and controlling the temperature of said admixture to control the rate of propagation of the polymer. The process is useful for producing random copolymers of vinyl acetate or styrene with more than 4 percent and up to greater than 20 percent by weight of (meth)acrylic acid.
摘要:
A magneto-optical isolator (20) for an optical circuit. The isolator includes a substrate, and an optical channel (350) disposed next to the substrate. The optical channel and substrate are configured to transmit optical radiation within the optical channel. The isolator further includes a photonic-crystal rotator (24) formed with the substrate and the optical channel. The rotator has at least one defect (52) and magnetic (M) and non-magnetic (N) materials.
摘要:
The present invention relates to a method of concurrently introducing multiple genes into plants and trees is provided. The method includes simultaneous transformation of plants with multiple genes from the phenylpropanoid pathways including 4CL, CAld5H, AldOMT, SAD and CAD genes and combinations thereof to produce various lines of transgenic plants displaying altered agronomic traits. The agronomic traits of the plants are regulated by the orientation of the specific genes and the selected gene combinations, which are incorporated into the plant genome.
摘要:
A method of inhibiting or preventing bonding between snow or ice and a substrate. The method may include applying an adhesive to a substrate, applying aggregate onto the adhesive and applying an anti-icing chemical thereon. Alternatively, the method may include grinding the aggregate, roughening the substrate and stimulating an aggregate/adhesive/anti-icing chemical composition.
摘要:
The present invention relates to a novel DNA sequence, which encodes a previously unidentified lignin biosynthetic pathway enzyme, sinapyl alcohol dehydrogenase (SAD) that regulates the biosynthesis of syringyl lignin in plants. Also provided are methods for incorporating this novel SAD gene sequence or substantially similar sequences into a plant genome for genetic engineering of syringyl-enriched lignin in plants.

摘要:
A method of locating mobiles via a dynamic base station. The method includes transmitting a first wireless signal from the dynamic base station at a first time, and receiving the first wireless signal at the mobile. The method also includes transmitting a second wireless signal from the mobile in response to receiving the first wireless signal, and receiving the second wireless signal at the dynamic base station at a second time. The method also includes determining a time difference between the first time and the second time, determining an angle of arrival of the second wireless signal, and locating the mobile based on the angle of arrival and the time difference.
