  • Publication number: 20180221377
    Abstract: The present invention is directed to methods of treating movement disorders by administering an effective amount of one or more adenosine A2A receptor antagonists to a patient in need thereof. The present invention also provides methods of decreasing the adverse effects of L-DOPA in patients receiving L-DOPA therapy in the treatment of Parkinson's disease. The present invention further provides methods and compositions for treating Parkinson's disease patients with sub-clinically effective doses of L-DOPA by combining L-DOPA treatment with an effective amount of one or more adenosine A2A receptor antagonists (i.e., L-DOPA sparing effect). The present invention further provides methods of effective treatment of Parkinson's disease by co-administering at least one adenosine A2A receptor antagonist, L-DOPA and a dopamine agonist and/or a COMT inhibitor and/or a MAO inhibitor.

  • Patent number: 7760999
    Abstract: An image capturing apparatus includes an image sensor which photo-electrically converts an object image formed by an objective lens, a shutter which is arranged between the objective lens and the image sensor, opens to set the image sensor in an exposure enable state, and closes to set the image sensor in a light-shielding state, a dark image acquisition unit which acquires a dark image by closing the shutter and causing the image sensor to accumulate charges, and a control unit which controls an aperture size of an aperture stop arranged at the objective lens, wherein if the aperture stop has a aperture size more than a predetermined aperture size before acquiring the dark image, the dark image acquisition unit acquires the dark image after the control unit controls the aperture stop to an aperture size not more than the predetermined aperture size.
