The present invention provides methods and pharmaceutical compositions of the human glycoprotein fetuin, or \u03b12-HS glycoprotein, or fragments thereof to mitigate tissue damage associated with ischemia, particularly in stroke or in myocardial infarction. In order to reduce commutation noise, it is proposed to influence the working range of the power-stage transistors with the aid of a component, in such a way that each transistors produces, during energization of each respective stator winding, a substantially constant current through the stator winding. The actuating unit includes a plurality of independent actuating parts for moving the other-side independent holding parts independently and a simultaneous operating part for simultaneously operating the holding parts. Each disk rotor assembly has a disk and a plurality of permanent magnets distributed along two or more circular paths in the disk inboard of the peripheral edge of the rotor. The prosthetic device comprises a highly oriented hollow body component between a superficial random oriented polymer layer and a base component. The received biometric data are compared with corresponding authentic biometric data which have previously been obtained from the genuine-user.
