... nonflying mammals ( Akodon montensis, Mus musculus and Rattus norvegicus ). Using standard pharmacokinetic techniques in intact animals, we confirmed the greater paracellular nutrient absorption in the fliers, comparing one species in each group. Then we conducted in situ intestinal perfusions on...

... are variable. Our goal was to examine the mechanical properties of these tissues under conditions mimicking the in vivo state. Tissue strains were measured in the rat( Rattus norvegicus ) soleus muscle directly from the spacing of metal markers implanted within the tissues of interest using an X-ray...
