Description of the nucleolar activity and karyotype in germinative cell lines of Rhodnius domesticus (Triatominae, Heteroptera)
(2004-12-01)
The purpose of this work was to study the karyotype, spermatogenesis and nucleolar activity at meiosis, in the species Rhodnius domesticus (Heteroptera, Triatominae). The testicular tubules were cytologically prepared by ...

Pattern of nucleolar activity during spermiogenesis in triatomines (Heteroptera, Reduviidae) as analysed by silver staining
(Faculty Press, 1997-01-01)
Nucleoli are the sites of biosynthesis of ribosomal precursors. In this work the nucleolar activity at interphase and the meiotic cells of the testis in five species of triatomines were analysed by means of silver staining. ...

Evaluation of argyrophilic nucleolar organizer regions in oral tumor progression
(Elsevier B. V., 2002)
The aim of this study was to compare the presence of nucleolar organizer regions (NORs) in normal oral mucosa, dysplasia and microinvasive carcinoma. All histological specimens were reviewed according to the modified ...

B Chromosomes in Nierembergia aristata (Solanaceae): Nucleolar Activity and Competition with the A Chromosomes
(Karger, 2011-01)
B chromosomes are additional dispensable chromosomes that may be present in some individuals, populations, or species, which have probably arisen from the A chromosomes but follow their own evolutionary pathway. Supposedly, ...
Patterns of nucleolar activity during spermatogenesis of two triatomines, Panstrongylus megistus and P-herreri
(Univ Florence Botany Inst, 1999-07-01)
The present work analyzed spermatogenesis in two species of triatomines (genus Panstrongylus) using silver-ion impregnation. The sex chromosomes of P. megistus and P. herreri had nucleolar organizing activity and became ...
