Myocardial infarction caused by coronary artery obstruction results in the loss of heart muscle, which is subsequently replaced scar tissue with limited therapeutic options. Cardiac patch based therapy has emerged as a promising strategy for treatment severe myocardial infarction. They are designed to be attached surface heart, that is, they meant “patch” injured thus restoring damaged or faili...

Cell membrane has a critical and vital role in functioning and existence of nerve cells that form central nervous system (CNS) in mammals. Disruption of nerve membrane that normally occurs following an accident injuring spinal cord is known to be the major cause of paralysis. In most occasions, spinal cord injuries are not leading to complete cut in spinal cord fibers but are known to cause cru...

The key information about any nanoscale system relates to the orientations and conformations of its parts. Unfortunately, these details are often hidden below diffraction limit, elaborate techniques must be used optically probe them. Here we present imaging 3D rotation motion metal nanorods, restoring distinct nanorod in full extent azimuthal polar angles. nanorods imprint their orientation ont...

An analytical method is proposed to get the amplitude-frequency and the phase-frequency characteristics of free/forced oscillators with nonlinear restoring force. The nonlinear restoring force is expressed as a spring with varying stiffness that depends on the vibration amplitude. That is, for stationary vibration, the restoring force linearly depends on the displacement, but the stiffness of t...
