Testing For Antimicrobial Activity Of A Material Patents (Class 435/32)
  • Patent number: 8986946
    Abstract: The invention relates to a method for real-time detection of viable microorganisms comprising: a. addition of a cell-permeable, phototautomeric compound to a micro-organism or other living cell; and b. measuring the fluorescent emission of said phototautomeric compound. Preferably the phototautomeric compound is salicylic acid, 2-hydroxy-1-naphtoic acid or 1-hydroxy-2-naphtoic acid. Further, the assay can he used to assess the antibiotic effect of a test compound. This test can be used as a high—throughput screening for compounds with antibiotic activity. Also part of the invention is the use of a cell permeable phototautomeric compound in a method for determining the viability of micro-organisms and for assessing the antibiotic effect of a test compound.

  • Publication number: 20150056169
    Abstract: Despite efforts of eradication and sanitation, Phytophthora ramorum persists in the United States and has been a problem in commercial nurseries since 2001. Detection in a nursery immediately causes the nursery to be under quarantine until the P. ramorum can be proven to be eradicated. Treatment with the biological control agent Trichoderma asperellum showed promise in laboratory results to remediate P. ramorum-infested potting soil. Sixteen T. asperellum isolates were screened, found to have variable mycoparasitic activities, and further tested in natural field settings. Field plots having P. ramorum-infested soil were treated with T. asperellum, a chemical and two different commercial biological control products and compared to non-treated infested soil. After 8 weeks, P. ramorum populations were not detected in the soil treated with T. asperellum isolate 04-22 showing that T. asperellum isolate 04-22 could remediate soils infested with P. ramorum under natural field conditions.

  • Publication number: 20140363497
    Abstract: Nanocells allow the sequential delivery of two different therapeutic agents with different modes of action or different pharmacokinetics. A nanocell is formed by encapsulating a nanocore with a first agent inside a lipid vesicle containing a second agent. The agent in the outer lipid compartment is released first and may exert its effect before the agent in the nanocore is released. The nanocell delivery system may be formulated in pharmaceutical composition for delivery to patients suffering from diseases such as cancer, inflammatory diseases such as asthma, autoimmune diseases such as rheumatoid arthritis, infectious diseases, and neurological diseases such as epilepsy. In treating cancer, a traditional antineoplastic agent is contained in the outer lipid vesicle of the nanocell, and an antiangiogenic agent is loaded into the nanocore. This arrangement allows the antineoplastic agent to be released first and delivered to the tumor before the tumor's blood supply is cut off by the antianiogenic agent.

    Abstract: This invention provides a family of compounds that inhibit Class II fructose 1,6-bisphosphate aldolase (FBA), which is implicated in the pathogenic activity of a broad range of bacterial and parasitic agents. The compounds were identified by empirical testing, and provide a basis for further derivatization and optimization of 8-hydroxyquinoline-2-carboxylic acid and related compounds. Crystal structure shows that the compounds don't bind directly to the catalytic site of the enzyme, and so are not defined simply as substrate analogs. Instead, they create a pocket by induced fit, resulting a powerful and specific inhibitory effect on FBA activity.

  • Publication number: 20140323340
    Abstract: The present invention relates to moving microorganisms to a surface, where they are grown in the presence and absence of antimicrobials, and by monitoring the growth of the microorganisms over time in the two conditions, their susceptibility to the antimicrobials can be determined. The microorganisms can be moved to the surface through electrophoresis, centrifugation or filtration. When the movement involves electrophoresis, the presence of oxidizing and reducing reagents lowers the voltage at which electrophoretic force can be generated and allows a broader range of means by which the target can be detected. Monitoring can comprise optical detection, and most conveniently includes the detection of individual microorganisms. The microorganisms can be stained in order to give information about their response to antimicrobials.

  • Patent number: 8865427
    Abstract: A perifusion device includes at least one sample container for cells, the sample container having an inlet and an outlet. The container receives test liquid through the inlet and discharges the liquid through the outlet. A manifold having a plurality of liquid inlets, control valves, and liquid outlets can be provided. A receptacle housing has a plurality of receptacles. A drive is connected to the receptacle housing for moving the receptacle housing. A programmable controller can be provided to control movement of the receptacle housing. The test liquid includes at least one stimuli for the cells. The liquid collected in the receptacles is analyzed to determine the response of the cells to the stimuli.

  • Publication number: 20140301912
    Abstract: A fluid delivery system may include a container that houses a medical fluid, a fluid pressurizing unit, and a fluid transfer set that transfers the medical fluid from the container to the fluid pressurizing unit. To validate the integrity and sterility of the fluid delivery system, the system may undergo testing protocols to evaluate the susceptibility of the system to pathogenic ingress, chemical degradation, and/or fluid cross-contamination between patient fluid delivery procedures. The testing protocols may help ensure that delivery system components used during multiple different fluid delivery procedures perform as well as if the components were replaced after each fluid delivery procedure.

  • Publication number: 20140287454
    Abstract: The present invention relates to a method of selecting (a) cell(s), (a) tissue(s) or (a) cell culture(s) with susceptibility to a selective CDK9 inhibitor. Also a method for determining the responsiveness of a mammalian tumor cell or cancer cell to treatment with a selective CDK9 inhibitor is described herein. In particular, the present invention provides for an in vitro method for the identification of a responder for or a patient sensitive to a selective CDK9 inhibitor, whereby the patient is suspected to suffer from NUT midline carcinoma (NMC). The present invention also relates to a method of monitoring or predicting the efficacy of a treatment of NUT midline carcinoma (NMC), wherein treatment with a selective CDK9 inhibitor is in particular envisaged. Also the use of a (transgenic) non-human animal or a (transgenic) cell having at least one rearrangement in the NUT gene for screening and/or validation of a medicament for the treatment NUT midline carcinoma (NMC) is described.
