IPC: C07K14/52
Filed: 1997-03-21
Abstract: The present invention provides methods and compositions for treatment of mammals afflicted with an ischemic or traumatic injury of the central nervous system. The present invention capitalizes in part upon the discovery that administration of a morphogen to such a mammal provides significant improvement in central nervous system function, even when administered after central nervous system tissue has been damaged. The methods involve the administration of dimeric proteins defined as morphogens, inducers of these morphogens, or agonists of the corresponding morphogen receptors, or implantation of cells stimulated by exposure to the morphogens. The proteins defined as morphogens comprise a structurally and functionally distinct family within the TGT- beta  superfamily. Osteogenic protein-1 (OP-1) is considered to be an exemplary and preferred member of this morphogen family.

Abstract: PURPOSE: Circuits of controlling variable impedance and driving off-chip for a semiconductor apparatus are provided to solve the problem of impedance mismatching with external devices by preventing the change of VDD voltage from interfering with the devices in the memory . CONSTITUTION: In a ZQ detector(100) of a circuit of variable impedance control and off-chip driver for semiconductor apparatus, the second voltage supply(VDDQ) drives the inverters(IN2,IN3) within an array driver(30-2). Thus each part of the array driver(30-2) operates individually according the first and second voltage supplies(VDD,VDDQ), all parts of transistor arrays operate to the second voltage supply(VDDQ). All the maximum amplitudes of the gate-source voltages of the PMOS transistors(P1-P6) and NMOS transistors(N1-N6) become the second voltage(VDDQ). Thus, the fluctuation of the first voltage(VDD) does not affect the gate-source voltages of the NMOS transistors(N1-N6) as the array(20-1) operates independently. In short, it is possible to prevent or minimize the error of transmitting the output signal because impedance matching is maintained even when the first voltage(VDD) varies.
