  • Publication number: 20100247444
    Abstract: To produce a labeled compound for a selected biological substance not using a radioisotope atom which has a risk of exposure to radioactivity and limitation on handling time but using a stable isotope atom; and that the labeled compound can be measured with good sensitivity separably from naturally occurring compounds of the selected biological substance which are substituted with the stable isotope atom. Choline as a biological substance is labeled by substituting the nitrogen atom of the quaternary ammonium group and all the carbon atoms of the methyl group attached to the nitrogen atom with respective isotopes 15N and 13C and used as a diagnostic agent.

  • Publication number: 20100112601
    Abstract: The present invention provides an anti-PAC1 monoclonal antibody capable of recognizing a PAC1 having a native structure, a PAC1 activity regulator (in particular, activity inhibitor) containing the antibody, a prophylactic/therapeutic agent for a disease associated with accentuation of a bioactivity of PAC1, containing the antibody, a diagnostic reagent for a disease associated with an abnormality of PAC1 activity, containing the antibody, and a screening method for a substance that regulates the expression of PAC1, using the antibody and a PAC1-expressing cell.

  • Patent number: 7400144
    Abstract: A magnetic resonance force microscope (MRFM) generator for producing an RF magnetic field uniformly over the whole of a sample. A cantilever with magnetic probe tip is self-excited. Under this condition, spins in the sample are controlled to produce a magnetic resonance force. A frequency demodulator measures the resonant frequency of the cantilever from the output detection signal from a cantilever displacement-measuring instrument based on the magnetic resonance force.

  • Publication number: 20050244822
    Abstract: The present invention provides a technique by which highly detailed gene expression profiling data for analyzing the gene function can be obtained safely and conveniently. It is a versatile non-destructive and high-resolution visualizing technique by which expression levels of genes can be monitored in real time, and which can be applied in vivo and to deep tissues. For instance, plasmids in which molecules that vary the NMR signal and can be quantified by PHM genes are incorporated downstream from promoters responding to the condition of medium, external stimuli and the like, are introduced into the cells. The level of polyphosphate in deep tissues and the like can then be quantified by 31P-NMR, allowing expression profiling of the promoter, both non-destructively and in real time.

  • Patent number: 5961015
    Abstract: An umbrella support attachment for a bicycle is provided which comprises a distal portion support member including a fastening portion to be attached to a seat stay of the bicycle and a support portion for supporting a distal portion of the umbrella, and a proximal portion support member including a fastening portion to be attached to a frame bar of the bicycle and a clipping portion for supporting a proximal portion of the umbrella. The umbrella support attachment is effective to carry an elongate object such as an umbrella on a bicycle without interfering with the operation of the bicycle and smooth movement of movable components of the bicycle.
