  • Publication number: 20140248657
    Abstract: The purpose of the present invention is to develop a method for producing a large amount of an insoluble aggregate that is equivalent to an insoluble aggregate formed in the brain of a patient. A method of producing an insoluble aggregate of a neurodegenerative-disease-related protein according to the present invention comprises the steps of: (1) introducing an insoluble fraction originated from the brain of a neurodegenerative disease patient into a cultured cell in which the neurodegenerative-disease-related protein can be expressed in a constitutive manner; (2) culturing the cultured cell into which the insoluble fraction has been introduced; and (3) extracting separating an insoluble fraction from the cultured cell. Optionally, the method may additionally comprise a step of amplifying the insoluble aggregate of the neurodegenerative-disease-related protein in the cultured cell.

  • Publication number: 20130295542
    Abstract: A simulating training device for assessment of cervical dilatation is provided. The device includes a supporting platform, a rotating plastic drum rigidly connected to a shaft and having a plurality of rubber-lined holes of varying diameters, a box which covers the rotating drum and has an opening, an indexing mechanism which has a spring-loaded lock and a slotted indexing wheel, a turn wheel which has an indication arrow, and a scale which identifies a diameter of each of the plurality of rubber-lined holes. Rotation of the turn wheel and the slotted indexing wheel causes one of the plurality of rubber-lined holes to be positioned in the center of the opening of the box one at a time. The turn wheel, the rotating drum and indexing mechanism are synchronized such that the indicating arrow of the turn wheel points to the diameter of the positioned hole on the scale.
