Two patients with acute blastic transformation of chronic myeloid leukemia (CML) associated with strikingly elevated platelet counts showed abnormalities of chromosome 3q in addition to the standard Philadelphia (Ph1) chromosome translocation. The first patient had an inversion of chromosome 3 (q21q26) cytologically identical to an inversion 3 previously reported in de novo acute megakaryoblast...
For nearly a century, biologists, and botanists in particular, have been interested in the determination and documentation of chromosome numbers for extant taxa (reviewed in Goldblatt & Lowry, 2011) as well as extinct ones (Laane & Hoiland, 1986; Masterson, 1994). These data have beenwidely used to evaluate the evolutionary pattern of chromosome number change and to estimate the base chromosome...
A survey of chromosome patterns in human leukemia was aimed at determining: departures from diploidy in different types of acute and chronic leukemia, influence of therapy on chromosome constitution, frequency of aneuploidy in freshly aspirated marrow compared with the same sample after short-term tissue culture. Exact chromosome counts were obtained in over 3,600 metaphases from 34 leukemic (i...
Chromosome abnormalities, Y-chromosome microdeletions, and androgen receptor gene CAG and GGN repeat polymorphisms in infertile Chinese men featuring severe oligospermia and azoospermia were analyzed. Ninety-six fertile men and 189 non-obstructive infertile men, including 125 patients with azoospermia and 64 with severe oligozoospermia, were studied. Seventeen infertile men (9.0%) carried a chr...
