In a recent volume of Blood, Yuan et a l l demonstrated internucleosomal cleavage of DNA in erythroid precursors obtained from the bone marrow (BM) of a patient with @-thalassemia major, “lesser” (but unquantitated) amounts of intemucleosomal cleavage in those from a @-thalassemia trait donor, and no evidence of such cleavage in erythroid precursors separated from normal BM. Although no other e...

We replicated Carpenter & Shah (1998) when the information was explicitly available on the visualization. However, when the information was not ...
