To the best of our knowledge, there has been no study with a large sample size investigating the morphology of kidneys, including "renal medullary pyramid
length, kidney size and parenchymal thickness" in newborns.
Normal renal column (arrow); medullary pyramid
(MP); renal cortex (c).
Renal cortical thickness was measured over a medullary pyramid
, perpendicular to the capsule as the shortest distance from the base of the medullary pyramid
to renal capsule (Figure 7).
The major diagnostic criteria for the diagnosis of CDC include location of the tumor in the medullary pyramid
(for small tumors), typical histology, and desmoplastic stroma with prominent inflammation including granulocytes, as well as exclusion of UC of upper urinary tract.
Study Number One Published in Neuroscience Letters ("Electrical Stimulation of the Medullary Pyramid
Promotes Proliferation and Differentiation of Oligodendrocyte Progenitor Cells in the Corticospinal Tract of the Adult Rat" [online May 2010]), this study provided the first in vivo demonstration in the adult CNS showing that electrical stimulation can selectively promote proliferation, or rapid increase, and development of myelinating cells.
