1.
Cytogenetic evidence for de novo synthesis of rRNA and involvement of nucleolar material in the organization of cell structures during spermiogenesis of Chariesterus armatus (Heteroptera, Coreidae)
Arakaki R, Souza H, Castanhole M, Bicudo H, Itoyama M
Genet Mol Res . 2010 Oct; 9(3):1877-85. PMID: 20882483
The nucleolar material of Chariesterus armatus was analyzed during spermiogenesis in cell preparations impregnated with silver nitrate. Nucleolar corpuscles were observed in spermatids at the beginning of the process, showing...

Heteropicnotic chromatin and nucleolar activity in meiosis and spermiogenesis of Limnogonus aduncus (Heteroptera, Gerridae): a stained nucleolar organizing region that can serve as a model for studying chromosome behavior
Castanhole M, Pereira L, Souza H, Bicudo H, Costa L, Itoyama M
Genet Mol Res . 2009 Feb; 7(4):1398-407. PMID: 19224457
Males of Limnogonus aduncus were found to have the sex chromosome system X0 and chromosome number 2n = 23 (22A + X0). Testis cells were stained with lacto-acetic orcein and...

Pattern of silver nitrate-staining during meiosis and spermiogenesis in testicular lobes of Antiteuchus tripterus (Heteroptera: Pentatomidae)
Souza H, Castanhole M, Bicudo H, Itoyama M
Genet Mol Res . 2008 Apr; 7(1):196-206. PMID: 18393223
The pattern of silver nitrate (Ag)-staining differed among testicular lobes of Antiteuchus tripterus. In general, these differences are in regard to the number, size, shape, coloring intensity, and location of...

Study of chromosomal and nucleolar aspects in testes of Nysius californicus (Heteroptera: Lygaeidae)
Souza H, Bicudo H, Itoyama M
Genet Mol Res . 2007 Feb; 6(1):33-40. PMID: 17299894
In Nysius californicus (family Lygaeidae, subfamily Orsillinae), a pest commonly known as the seed bug, the chromosome complement is 2n = 16 (12A + 2m + XY), testes are formed...

New evidence for nucleolar dominance in hybrids of Drosophila arizonae and Drosophila mulleri
Oliveira C, Bicudo H, Itoyama M
Genet Mol Res . 2006 Dec; 5(4):632-7. PMID: 17183474
Drosophila mulleri (MU) and D. arizonae (AR) are cryptic species of the mulleri complex, mulleri subgroup, repleta group. Earlier cytogenetic studies revealed that these species have different regulatory mechanisms of...

Meiosis aspects and nucleolar activity in Triatoma vitticeps (Triatominae, Heteroptera)
Severi-Aguiar G, Lourenco L, Bicudo H, Azeredo-Oliveira M
Genetica . 2006 Feb; 126(1-2):141-51. PMID: 16502091
Some aspects of both the nucleolar organizer activity and meiosis were studied in the testes of Triatoma vitticeps (Heteroptera, Triatominae). The techniques used included squashing followed by lacto-acetic orcein staining,...

Morphometric study by image analysis of Ag-stained nucleoli in thyroids bearing proliferating lesions
Abdo-Banhos C, Cordeiro J, Rosa C, Bicudo H
J Submicrosc Cytol Pathol . 2004 Aug; 36(1):37-43. PMID: 15311673
The Ag-NOR staining technique and image analysis were used to evaluate morphological parameters (area, perimeter and axis ratio) in nucleoli from normal thyroids and from thyroids bearing proliferating lesions (carcinomas,...
