Deprenyl Can Mediate Neuronal Protection Rather than Neuronal Rescue

Background and Objective: Deprenyl is a drug for the treatment of Parkinson’s disease, where the dopaminergic neurons are the target of this drug. Several reports also documented that deprenyl has an effect on the sensory and motor neurons. There are some reports about the mode of action of deprenyl on m...

deprenyl can mediate neuronal protection rather than neuronal rescue

background and objective: deprenyl is a drug for the treatment of parkinson’s disease, where the dopaminergic neurons are the target of this drug. several reports also documented that deprenyl has an effect on the sensory and motor neurons. there are some reports about the mode of action of deprenyl on motoneurons as a neuroprotective agent, while others believe that deprenyl acts as a neurores...

A chain that accelerates rather than slows due to collisions: how compression can cause tension

When two objects collide their velocities change in response to the compressive (pushing) force between them. The difference in (normal) velocities between the objects is thus eliminated or reversed. However, for non-rigid objects collisions are more subtle. Surprisingly, when a long chain moving lengthwise collides with, say, a wall or floor, the chain can be pulled into the wall (instead of p...
