  • Publication number: 20210080465
    Abstract: The present disclosure provides methods and compositions for prognosing Chronic Lymphocytic Leukemia (CLL) or monitoring CLL therapy in a subject, by contacting a blood sample from a subject having CLL with one or more tyrosine phosphorylation (pTyr) probes to promote binding of tyrosine phosphorylated proteins in the blood sample to the one or more pTyr probes to generate pTyr probe-protein complexes; and detecting an amount of pTyr probe-protein complexes in the blood sample; wherein an amount of pTyr probe-protein complexes in the blood sample is compared to a control to indicate expected progression of CLL, or therapeutic efficacy of CLL therapy in the subject.

  • Patent number: 8911422
    Abstract: An object of the present invention is to efficiently inject a drug (physiologically active substance). Therefore, a micro-needle device 1 comprises a base plate 2 and a micro-needle 3 installed on the base plate 2. A coating agent containing the physiologically active substance is coated at least at a part of the micro-needle 3, and a coating range thereof is 100 to 230 ?m including the top of the micro-needle 3. A load due to the energy of 0.2 to 0.7 J/cm2 is applied to the micro-needle device 1 which is in contact with the skin.

  • Publication number: 20130226098
    Abstract: An applicator 10 for applying a microneedle to a skin includes a tubular housing 11, a piston 20 which transmits a biasing force of a spring 40 to the microneedle, fixation means (a claw receiving portion 16 and claw portions 22a) for fixing the piston 20 against the biasing force of the spring 40 in the housing 11, and a cap 30 provided near a first end of the housing 11. A projecting portion 31 for releasing the piston 20 fixed by the fixation means is provided at a surface of the cap 30 facing the piston 20. The cap 30 is provided to be freely movable in an extending direction of the housing 11 such that the projecting portion 31 can contact the fixation means when the piston 20 is fixed by the fixation means.

  • Patent number: 8519773
    Abstract: A method for switching between first and second voltages is provided. Initially, a first voltage is provided from a first input terminal to an output terminal through a first MOS transistor, and the first MOS transistor is deactivated. A back-gate of a second MOS transistor is shorted to the output terminal in response to the deactivation of the first MOS transistor and after a settling interval, and the second MOS transistor is activated while its back-gate is shorted to the terminal so as to provide a second voltage from a second input terminal to the output terminal.
