Issues

Cover picture: Immunofluorescence analysis showing myosin heavy chain (MHC) I (blue), MHC IIa (green), MHC IIx (unstained), and MHC IIb (red) in mouse extensor digitorum longus (EDL; top left), lumbrical (middle left), and soleus muscle (bottom left). Despite sharing a fast fiber-type profile with EDL (presented in bar [top right] and pie [bottom right] graphs), lumbrical is functionally closer to soleus with regards to posttetanic potentiation (see research article by Smith et al., 297–308).
