  • Publication number: 20200114024
    Abstract: A composition for treating cancerous cells in a subject having an immune system includes a virus in the Yatapoxvirus genus having at least one mutation. In one embodiment, the mutation results in suppressed expression of a TNF binding protein by the virus. In another embodiment, the mutation results in suppressed expression of thymidine kinase (“TK”) by the virus. In another embodiment, the mutation arms the virus with a transgene to express a bacterial flagellin. The mutations can be present singly or in combination. Additional aspects include a method of treating cancerous cells with a composition as described herein, and a method of delivering at least one gene to cancerous cells in a subject.

  • Publication number: 20170000919
    Abstract: A sterilization container with a sensor module for monitoring the environmental characteristics internal to the container. The sensor module includes a normally closed end bore. A sensor is disposed in the closed end void space. Other sensors also part of the module monitor the pressure and temperature of the environment inside the container. Based on the measurements of the environment in the container and the environment within the closed end void space it is possible to determine the extent to which the container is filled with saturated steam.

  • Publication number: 20040082138
    Abstract: A method of forming a mask for bombardment of a semiconductor substrate with high energy particles and a mask formed thereby are provided. A patterned layer of a blocking material is formed over a mask substrate to define a high energy particle bombardment mask pattern. The blocking material has sufficient thickness in the mask pattern to substantially shield the semiconductor substrate from selected high energy particles in areas overlapped by the mask pattern when the mask is aligned over the semiconductor substrate. The mask includes a mask substrate having a patterned layer of blocking material formed thereon to define a high energy particle bombardment mask pattern. The blocking material has sufficient thickness in the mask pattern to substantially shield the semiconductor substrate from selected high energy particles in areas of the semiconductor substrate overlapped by the mask pattern when the mask is aligned over the semiconductor substrate.

  • Patent number: 6413921
    Abstract: The present invention provides an antimicrobial composition for disinfection of a skin surface in preparation for surgery. The antimicrobial composition comprises parachlorometaxylenol (PCMX) and an anionic surfactant composition which exhibits both a high degree of antimicrobial efficacy and low skin irritability properties. In a preferred embodiment, the composition comprises an anionic surfactant composition comprising a surfactant having a hydrophobic portion consisting of a linear alkyl and a hydrophilic portion having ethoxylation termination with a sulfonate anionic group, and a sarcosine surfactant. A preferred surfactant composition further comprises a foaming anionic surfactant, such as sodium lauryl sulfate. The antimicrobial composition can be used in skin disinfecting formulations, such as scrub formulations and pre-operative skin disinfecting formulations. In one embodiment, the composition comprises about 3.3% parachlorometaxylenol.
