On the cover: Light microscopy images of renal glomeruli (40 original magnification) of Dahl salt-sensitive (SS/Mcw) rats fed a 4.0% NaCl diet and treated with vehicle (left panel) or mycophenolate mofetil (MMF) (right panel) for 3 weeks. Glomerular sclerosis (blue fibrotic tissue and collapsed capillary structure) is evident in the kidneys of vehicle-treated SS/Mcw rats. Visibly less glomerular and tubular injury is present in the kidneys of the SS/Mcw treated with MMF (see page 149.)
