Cromosomas y localizacion de Ag-NOR en poblaciones fluviales de Salmo trutta fario L. 1758 (Salmoniformes: Salmonidae) del Desierto de Atacama, Chile [PDF]
Salmo trutta fario L. 1758, presented a chromosome number 2n = 80 and a fundamental number NF = 100. The haploid chromosome set consists of seven metacentric chromosomes, three submetacentric, one subtelocentric and 29 telocentrics.

Silver-negative NORs in Pamphagus ortolaniae (Orthoptera: Pamphagidae)
The present paper reports some cytogenetic peculiarities observed in the Ag-NORs of Pamphagus ortolaniae chromosomes, the unusual behaviour of ribosomal sites after silver staining and the intense Ag-positive reaction of centromeric regions at ...

A rapid alternative technique for obtaining silver-positive patterns in chromosomes
Silver nitrate chromosome staining to evidence nucleolar organizer regions (NORs) is a widely adopted methodology. The aim of the present work was to improve this technique, reducing the preparation time without decreasing the quality of the results ...

Ag-NOR staining and satellite association in lymphoproliferative disorders
The nucleolar organizer regions (NORs) activity and the frequency of satellite associations (SA) in peripheral blood lymphocytes from patients with two chronic lymphoproliferative disorders were studied: 10 cases with B-cell chronic lymphocytic leukemia (B-CLL) and 10 with mycosis fungoides (MF). Thirteen healthy individuals formed the MF control group,

The significance of cytogenetics for the study of karyotype evolution and taxonomy of water bugs (Heteroptera, Belostomatidae) native to Argentina [PDF]
Male meiosis behaviour and heterochromatin characterization of three big water bug species were studied. Belostoma dentatum (Mayr, 1863), B. elongatum Montandon, 1908 and B. gestroi Montandon, 1903 possess 2n = 26 + X1X2Y (male).
