摘要:
AT4 receptor agonists are potent activators of angiogenesis and can be used to treat diseases that are characterized by vascular insufficiency. AT4 receptor antagonists, which are potent inhibitors of angiogenesis, and can be used as anti-angiogenic agents for the treatment of cancer, diabetic retinopathy, rheumatoid arthritis, psoriasis, atherosclerotic plaque formation, and any disease process that is characterized by excessive, undesired or inappropriate angiogenesis or proliferation of endothelial cells.
摘要:
The present disclosure concerns embodiments of a thermal switch used to control the transfer of heat from a heat source to a heat sink. According to one aspect, the thermal switch can be activated, or turned “on”, so as to establish a path of low thermal resistance between the heat source and the heat sink to facilitate the transfer of heat therebetween. The thermal switch can also be de-activated, or turned “off”, so as to establish a path of high thermal resistance between the heat source and the heat sink to minimize or totally prevent the transfer of heat between the heat source and heat sink. In certain embodiments, the thermal switch includes at least drop of a thermally conductive liquid that thermally couples the heat source to the heat sink whenever the switch is activated.
摘要:
Sunburn and insect damage to fruit and vegetable crops is significantly reduced by treatment of both fruit and foliage with a preventative amount of thixotropic smectic clay material, chemically altered to render its surface lipophilic, which is combined with a wax emulsion comprising a matrix of complex hydrocarbons, an emulsifying agent and water. In the practice of this invention the sunburn and insect protective composition is further diluted in an aqueous solution that is sprayable by commercial applicators.
摘要:
The present disclosure concerns apparatus and methods useful in estimating crop yields of plants that are supported on a trellis. According to one aspect, a method for measuring the mass of trellised plant structures includes measuring the tension of a support wire of the trellis structure on which the plant structures are supported, such as with a load cell placed in-line with the support wire. The tension of the support wire is converted into the mass of new plant growth supported on the support wire, using, for example, an empirically derived algorithm specific to the trellis structure.
摘要:
cDNAs encoding gymnosperm monoterpene synthases have been isolated and sequenced, and the corresponding amino acid sequences have been determined. Modified host cells are provided that have been transformed, transfected, infected and/or injected with a recombinant cloning vehicle and/or DNA sequence encoding a monoterpene synthase of the invention. Thus, systems and methods are provided for the recombinant expression of recombinant monoterpene synthases that may be used to facilitate their production, isolation and purification in significant amounts.
摘要:
Oxygenase enzymes and the use of such enzymes to produce paclitaxel (Taxolnull) related taxoids, as well as intermediates in the Taxolnull biosynthetic pathway are disclosed. Also disclosed are nucleic acid sequences encoding the oxygenase enzymes. Particular oxygenase enzymes include the disclosed taxoid-14-beta hydroxylases.
摘要:
This invention provides the identification of a truncation polymorphism of the mdr1 gene that is linked to ivermectin sensitivity in subjects, such as collies. Also provided are methods for detecting drug transport sensitivity in a subject, and animal models and in vitro cell systems using cells from animals having an mdr1 truncation.
摘要:
A novel gene encoding a 37 kDa outer membrane protein from Campylobacter coli M275 has been cloned and sequenced. This protein has been named CadF and is expressed in a large number of clinical isolates of Campylobacter species. The invention also provides assays for detecting the presence of pathogenic Campylobacter species based on the antibody-based detection of CadF, or the polymerase chain reaction (PCR)-based amplification of a segment of the C. coli cadF gene.
摘要:
cDNA encoding (-)-limonene-6-hydroxylase from spearmint and (-)-limonene-3-hydroxylase from peppermint have been isolated and sequenced, and the corresponding amino acid sequences have been determined. Accordingly, isolated DNA sequences are provided which code for the expression of (-)-limonene-6-hydroxylase from spearmint (SEQ ID No:1, from Mentha spicata) and (-)-limonene-3-hydroxylase from peppermint (SEQ ID No:8, from Mentha piperita). In other aspects, replicable recombinant cloning vehicles are provided which code for limonene hydroxylase or for a base sequence sufficiently complementary to at least a portion of the limonene hydroxylase DNA or RNA to enable hybridization therewith (e.g., antisense limonene hydroxylase RNA or fragments of complementary limonene hydroxylase DNA which are useful as polymerase chain reaction primers or as probes for limonene hydroxylase or related genes). In yet other aspects, modified host cells are provided that have been transformed, transfected, infected and/or injected with a recombinant cloning vehicle and/or DNA sequence encoding limonene hydroxylase. Thus, systems and methods are provided for the recombinant expression of limonene hydroxylase that may be used to facilitate the production, isolation and purification of significant quantities of recombinant limonene hydroxylase (or of the primary enzyme products, trans-carveol or trans-isopiperitenol, respectively) for subsequent use, to obtain expression or enhanced expression of limonene hydroxylase in plants to attain enhanced production of trans-carveol or trans-isopiperitenol as a predator or pathogen defense mechanism, or may be otherwise employed for the regulation or expression of limonene hydroxylase or the production of trans-carveol or trans-isopiperitenol.
摘要:
A new and distinct variety of self-infertile sweet cherry tree which bears very large mahogany red colored fruits that are 10-14 grams in weight. Its fruits, which are well suited for the high quality early season premium market, ripen six to nine days ahead of the commercially grown `Bing` variety, to which in many ways the new variety is comparable.
