C-band polymorphism in non-Hodgkin lymphoma [PDF]

Hereditas, 2008
The pattern of heteromorphism in C‐band positive constitutive heterochromatin of human chromosomes Nos. 1, 9, and 16 was studied in peripheral lymphocytes from 78 patients with non‐Hodgkin lymphoma and 78 control individuals. The parameters of the heterochromatic regions analyzed were relative size, symmetry‐asymmetry within homologous pairs, and ...

Chromosome studies of Brazilian vespertilionids Lasiurus cinereus and Lasiurus ega (Mammalia, Chiroptera)

Iheringia: Série Zoologia, 2004
Cytogenetical studies based on conventional coloration by Giemsa, C-banding and Ag-NOR were performed on 2 species of bats from the vespertilionid family: Lasiurus cinereus (Beauvois, 1796) and Lasiurus ega (Gervais, 1856). The 2n was 28 and FN was 48 in
