  • Patent number: 7608433
    Abstract: The invention relates to a multiplex real-time RT-PCR assay with a heterologous internal control system (i.e., EGFP-RNA) for the simple and fast diagnosis of classical swine fever virus (CSFV). Primers and FAM-labeled TaqMan probes, specific for CSFV were selected by analyzing the consensus sequence of the 5?-non translated region of various CSFV strains. For determining the analytical sensitivity an in vitro transcript (T7-PC3Alf) of the 5? NTR was constructed and tested. Furthermore, a primer-probe system for the detection of the internal control sequence was established, and a multiplex assay using CSF-System 1 and the IC real-time PCR could be performed as a one-tube assay without loss of sensitivity or specificity.

  • Patent number: 7439268
    Abstract: The present invention provides compositions and methods for administering florfenicol to mammals. The compositions contain a prodrug of florfenicol in a pharmaceutically acceptable carrier. In one embodiment the prodrug is an esterized form of florfenicol. Examples of suitable prodrugs include one or a combination of one or a combination of the following: florfenicol acetate, florfenicol propionate, florfenicol butyrate, florfenicol pentanoate, florfenicol hexanoate, florfenicol heptanoate, florfenicol octanoate, florfenicol nanoate, florfenicol decanoate, florfenicol undecanoate, florfenicol dodecanoate, and florfenicol phthalate. In another embodiment the prodrug is converted into the florfenicol in vivo by the action of one or more endogenous esterases. The invention also provides new compounds, pharmaceutical compositions containing the compounds, and methods for their administration.

  • Patent number: 7404964
    Abstract: The present invention provides compositions and methods for extending the release times and lowering the toxicity of pharmacologically active compounds. The compounds comprise a salt of the pharmacologically active compound with a lipophilic counterion and a pharmaceutically acceptable water soluble solvent combined together to form an injectable composition. The lipophilic counterion may be a saturated or unsaturated C8-C22 fatty acid, and preferably may be a saturated or unsaturated C10-C18 fatty acid. When injected into a mammal, at least a portion of the composition precipitates and releases the active compound over time. Thus, the composition forms a slowly releasing drug depot of the active compound in the mammal. Therefore, the present invention enables one to provide a controlled dose administration of the active compound for a periods of up to 15 days or even longer.

  • Patent number: 6893880
    Abstract: The present invention provides a method and a device that utilizes capillarity-mediated, chromatographic transport, for the qualitative or semi-quantitative analysis of selected analytes in liquid samples. The device utilizes an applicator/collection device for collecting and administering the sample to the flow path such that reagent(s) flow through the applicator/collection device, washing the sample into the reaction pathway. The device further utilizes an air gap between the initial location of the reagent and the reaction pathway to funnel the reagent efficiently through the sample so as to collect all or substantially all of the sample and make it available for the reaction(s).

  • Patent number: 6517778
    Abstract: A fluorescent immunoassay employing the interior surface of a capillary tube is provided. Devices to permit immunoassays using one or more capillary tubes, an apparatus for use with the devices, and a process for screening for analyte in a sample using the devices and apparatus are also provided. Samples suspected of containing analyte are added to a disposable self-contained sample tray containing one or more sample wells, mixed with a reagent, drawn into one or more spaced-apart capillary tubes held within a disposable cartridge connected to an analytical apparatus, reacted with a binding member on the surface of the capillary tube, washed to stop the reaction, and dried by the apparatus. The capillary tube is then exposed to a signal generation device to create a fluorescence signal that is detected using a signal detector. The apparatus determines the presence of the analyte and optionally determines the amount of analyte present in the sample, and presents the results to the operator.

  • Patent number: 6413778
    Abstract: The present invention relates to devices, methods and kits for the detection and identification of crystals which may be present in a biological fluid, such as urine from a cat. The device may include a filter and an absorbent material. The fluid may be transferred onto the filter, and fluid passes through the filter and into the absorbent material, thereby isolating crystals on a surface of or within the structure of the filter or membrane. The crystals are then available for staining which will reveal a determining component of the crystals. The device may also include a member for inhibiting backflow from the absorbent material to the filter. The present invention also provides methods for detecting and identifying crystals which may be present in biological fluids. The methods include the steps of isolating the crystals on the surface of or within the structure of a filter or membrane, and contacting the crystals with an indicator which is specific for a determining component of the crystals type.
