  • Flow meter
    Patent number: 8141436
    Abstract: A flow meter to be used in a hole drilled in the bedrock for measuring stream flows in bedrock fractures which are transversal to the hole. The flow meter comprises an elongated body having a cross section which is substantially smaller than the diameter of the hole; separating members placed at a distance from each other in the longitudinal direction of the body for separating the examined section from the other parts of the hole in a substantially pressure-tight manner; dividing members for dividing the examined section into two sectors in the longitudinal direction of the hole; and a flow channel extending through the body and equipped with a flow sensor for measuring the direction and rate of the flow between the sectors. In accordance with the invention, the dividing members are formed of thin and elastic sealing strips, which have been fixed to the body and, being substantially perpendicular to the surface of the body, arranged to surround and delimit the sectors.

  • Urokinase-type plasminogen activator receptor
    Patent number: 6248712
    Abstract: Activation of plasminogen to plasmin is inhibited by preventing the binding of a receptor binding form of urokinase-type plasminogen activator to a urokinase-type plasminogen activator receptor in a mammal, thereby preventing the urokinase-type plasminogen activator from converting plasminogen into plasmin. DNA fragments which encode for soluble, active fragments of the urokinase-type plasminogen activator receptor are provided.

  • Vectors and methods for recombinant production of uPA-binding fragments of the human urokinase-type plasminogen receptor (uPAR)
    Patent number: 5891664
    Abstract: Activation of plasminogen to plasma is inhibited by preventing the binding of a receptor binding form of urokinase-type plasminogen activator to a urokinase-type plasminogen activator receptor in a mammal, thereby preventing the urokinase-type plasminogen activator from converting plasminogen into plasmin. DNA fragments which encode for soluble, active fragments of the urokinase-type plasminogen activator are provided.
