of the true giants in the history of science. Marshall Nirenberg, the man who deciphered the genetic code, was taken from us by a rare neuroendocrine cancer. He was 82 years old. I was one of the many scientists who had the good fortune to be trained in Marshall's lab, to be exposed to his brilliance , to be instilled with his values, and to be inspired by his enthusiasm for the discovery of im...

The ligament of Marshall is an epicardial vestigial fold that contains the vein of Marshall and a myocardial sleeve called the Marshall bundle (MB).
