  • Patent number: 6090565
    Abstract: The present invention involves the identification of sphingoglycolipid species that are indicative of multidrug resistance in certain types of cells, including cancer cells. The association of multidrug resistance with the expression of certain sphingoglycolipids provides a new method for identifying multidrug resistant cancers. In addition, it has been determined that reducing the levels of certain sphingoglycolipids results in enhanced chemosensitivity of drug resistant cancer cells. This offers the opportunity to develop new treatments for multidrug resistant cancers.

  • Patent number: 6087493
    Abstract: The present invention has identified compounds with extended aromatic chromophores that bind the G-quadruplex formed by the folding of single-stranded human telomeric DNA. These compounds have been shown to be effective telomerase inhibitors and are contemplated to be useful in developing cancer treatments. A model of cationic porphyrin interaction with quadruplex DNA by intercalation has been established and in combination with structure activity relations has provided novel porphyrin compounds that exhibit discrimination between binding duplex and quadruplex DNA and show improved activity against telomerase.

  • Patent number: 6087129
    Abstract: The present invention a provides methods for production of heterologous polypeptides using a variety recombinantly engineered secretory cell lines. The common feature of these cell lines is the absence of expression of at least one endogenous polypeptide. The host cell machinery normally used to produce the endogenous polypeptide is then usurped for the purpose of making the heterologous polypeptide. Also described are methods engineering cells for high level expression, methods of large scale protein production, and methods for treatment of disease in vivo using viral delivery systems and recombinant cell lines.

  • Patent number: 6085930
    Abstract: A package for maintaining a modified atmosphere around contents being contained therein when stored in an ambient environment is set forth. The modified-atmosphere package includes a tray, a membrane, and a structural member. The tray has a base and side walls extending upwardly from the base. The side walls and the base define a cavity wherein the contents are disposed. A membrane is attached to a top portion of the side walls and encloses the cavity. The structural member is detachably connected to the top portion of the side walls and is disposed above the membrane to prevent the membrane from contacting an external structure which inhibits permeation through the membrane. The structural member also has at least one opening for exposing the membrane to the ambient environment. Stacking means at the base of the tray and the top of the structural member allow the modified-atmosphere packages to be easily stacked.

  • Patent number: 6084108
    Abstract: Fungicides having thiophene rings may be made from the intermediate compound 3-carbomethoxy-4,5-dimethylthiophene. That compound, and related compounds, may be produced by reacting an alpha mercaptoketone, e.g., 3-mercapto-2-butanone, with an acrylate, e.g., methyl-3-methoxy acrylate, in the presence of an alkoxide base, e.g., NaOMe, to form the substituted tetrahydrothiophene, followed by conversion to the aromatic thiophene with an acid treatment. The substituted tetrahydrothiophene is a novel compound.

  • Patent number: 6083691
    Abstract: Compositions and methods for detecting the conversion to mucoidy in Pseudomonas aeruginosa are disclosed. Chronic respiratory infections with mucoid Pseudomonas aeruginosa are the leading cause of high mortality and morbidity in cystic fibrosis. The initially colonizing strains are nonmucoid but in the cystic fibrosis lung they invariably convert into the mucoid form causing further disease deterioration and poor prognosis. Mucoidy is a critical P. aeruginosa virulence factor in cystic fibrosis that has been associated with biofilm development and resistance to phagocytosis. The molecular basis of this conversion to mucoidy is also disclosed. The present invention provides for detecting the switch from nonmucoid to mucoid state as caused by either frameshift deletions and duplications or nonsense changes in the second gene of the cluster, mucA. Inactivation of mucA results in constitutive expression of genes, such as algD, dependent on algU for transcription.

  • Patent number: 6083496
    Abstract: Described herein are novel specific, pure competitive inhibitors of natural polyamine transport in mammalian cells. Despite their low molecular weight, the inhibitors of the present invention stay virtually impermeant to the cell and display minor non-specific effects while exhibiting a very high affinity for the carrier. More specifically described are synthetic derivatives of original polyamines, wherein the original polyamine is modified to comprise an amido group immediately linked to the polyamine backbone. A side chain may be anchored to the amido group and provide for the formation of dimeric synthetic derivatives or its labelling and subsequent usage as a marker for the polyamine transporter.

  • Patent number: 6081092
    Abstract: The driver circuit (10) comprises a first triac or the like (11) for connection in series with the stator winding (5, 6) of the motor between the terminals (12, 13) of an alternating-current voltage supply, the gate of the first triac (11) being arranged for connection to an intermediate point (C) of the stator winding (5, 6) of the motor (M). A second triac or the like (15) is connected between the intermediate point (C) of the winding (5, 6) and the terminal (13) of the voltage supply to which the first triac (11) is connected. A control circuit (15-27) is connected to the gate of the second triac (15) such that, each time the motor (M) is connected to the voltage supply, it initially makes the second triac (15) conductive and consequently cuts off the first triac (11) for a predetermined initial period of time, and cuts off the second triac (15) and allows the first triac (11) to become conductive after this period of time.

  • Patent number: 6080914
    Abstract: Promoters and genes isolated from genomic DNA of strawberry plants are disclosed. Both the promoters and genes are capable of tissue-specific expression in transgenic plants. A plant promoter that is a nucleic acid region located upstream of the 5' end of a plant DNA structural coding sequence that is transcribed at high levels in ripening fruit tissue. This promoter region is capable of conferring high levels of transcription in ripening fruit tissue and in developing seed tissues when used as a promoter for a heterologous coding sequence in a chimeric gene. The promoter and any chimeric gene in which it may be used can be used to obtain transformed plants or plant cells. A DNA coding sequence that codes for a gene that is highly transcribed in ripening fruit tissue of Fragaria X ananassa. This coding sequence can be used to obtain a cDNA probe useful in obtaining analogous promoters from a homologous coding sequence in other plant species.

  • Patent number: 6078253
    Abstract: A multiple sensing technology-based occupancy sensor. Ultrasonic and infrared sensors are used to produce first and second occupancy estimator signals that are combined using a fusion based detection algorithm to produce a combined estimator signal. The combined estimator is then used to switch electrical loads when the combined estimator signal is above a predetermined threshold. The result is an occupancy sensor that has a very high probability of occupancy detection and a low probability of false tripping. In addition, infrared sensitivity is adjusted based upon an estimation of the background noise in order to minimize the occurrence of false tripping.
