  • Patent number: 9682121
    Abstract: The invention discloses application of irisin in the preparation of drugs for preventing myocardial ischemia reperfusion injuries. Experimental results show that irisin can decrease the myocardial infarction area caused by ischemia reperfusion, reduce the increase of the contents of lactate dehydrogenase (LDH), troponin (cTnI), creatine kinase (CK), and other myocardial enzyme markers caused by ischemia reperfusion, meanwhile reducing the inflammatory response, myocardial apoptosis, and oxidative stress response caused by myocardial ischemia reperfusion, promote peroxysome proliferator-activated receptor ? nuclear translocation, and inhibit nuclear transcription factor NF-?B nuclear translocation and accordingly decrease myocardial structure injuries and load increase caused by ischemia reperfusion. Therefore, irisin can be used for preventing and decreasing myocardial reperfusion injuries and has important clinical significance on the treatment of myocardial ischemia.

  • Patent number: 9376095
    Abstract: A vehicle control method includes iteratively modifying a level of braking of the vehicle until it is determined that the vehicle has substantially lost traction with respect to the road surface, then determining the coefficient of friction between the road surface and the tire based on the level of braking at the time the vehicle substantially lost fraction. In one embodiment, previous ABS or other vehicle control events are used as a basis for estimating an initial level of braking to be applied during the friction measurement procedure. Such a deterministic maneuver can also function as a collision warning to the driver of the vehicle.
