    摘要: This invention relates to extracellular protein-protein interactions and their possible therapeutic uses. More particularly, this invention describes the interaction between Draxin, particularly fragments binding to γ-Netrins comprising SEQ ID NO.:1, 2 or 3, and variants thereof, with γ-Netrins, and the use of this interaction to disrupt γ-Netrin/Netrin receptor interactions. The invention also relates to diagnostic and/or therapeutic uses of Draxin or fragments or variants thereof, as well as to an antibody against Draxin inhibiting binding of Draxin to γ-Netrins. Further, the invention relates to fragments of γ-Netrins, in particular Draxin-binding Netrin1-fragments comprising SEQ ID NO.: 51 and variants thereof, as well as to an antibody against γ-Netrins inhibiting binding of γ-Netrins to Netrin receptors.

    摘要: An apparatus for terminating or unpinning rotating electric activity in a cardiac tissue analyzes an electric parameter for rotating electric activity in the cardiac tissue, and generates electric pulses in response to the rotating electric activity. The electric pulses are applied as electric field pulses and include a plurality of rotating electric activity synchronization pulses arranged at first intervals and a rotating electric activity termination or unpinning pulse following to the last synchronization pulse at a second interval which is similar to one of the first intervals. A maximum electric field strength caused the synchronization pulses is not more than 82% of a maximum electric field strength caused by the termination or unpinning pulse, and an electric pulse energy delivered to the cardiac tissue by each of the synchronization pulses is not more than 67% of an electric pulse energy delivered by the termination or unpinning pulse.

    摘要: Each of monodisperse spherical microcapsules for seeding a transparent fluid to track movements of the fluid both in translational and rotational directions comprises a core; a shell; and 1 to 5 light reflecting solid integral particles. Each of the particles reflects incoming light in a defined direction; and each of the particles is embedded in the core and fixed in its orientation with regard to the shell. The shell and the core are transparent for the incoming light to be reflected by the particles entering and exiting the microcapsule. The shell has a thickness of not more than λ, λ being a wavelength of the incoming light, so that the shell does essentially not deflect the incoming light entering and exiting the microcapsule. The core includes a main component of the fluid such that a refraction index of the core essentially matches a refraction index of the fluid.
