In this overview, we summarize the findings of the literature with regards to physiology and
pathophysiology of ultra-marathon running. The number of ultra-marathon races and the …

Imaging plays an important role in the diagnosis and therapeutic response evaluation of
muscular diseases. However, one important limitation is its incapacity to assess the in vivo …

This manuscript describes the use of ultrasound elastography, with the exception of liver
