1. [PROVISIONAL] Heterochromatin and numeric chromosome evolution in Bignoniaceae, with emphasis on the Neotropical clade Tabebuia alliance
Abstract Bignoniaceae is a diverse family composed of 840 species with Pantropical distribution. The chromosome number 2n = 40 is predominant in most species of the family, with n = 20 formerly being considered the haploid base number. We discuss here the haploid base number of Bignoniaceae and examine heterochromatin distributions revealed by CMA/DAPI fluor

2. Comparative cytogenetics in three Melipona species (Hymenoptera: Apidae) with two divergent heterochromatic patterns
Abstract The genus Melipona is subdivided into four subgenera based on morphological characteristics, and two groups based on cytogenetic patterns. The cytogenetic information on this genus is still scarce, therefore, the goal of this study was to characterize Melipona paraensis, Melipona puncticollis, and Melipona seminigra pernigra using the following tech

3. Karyotype analysis in Bignonieae (Bignoniaceae): chromosome numbers and heterochromatin
ABSTRACT Chromosome numbers and heterochromatin banding pattern variability have been shown to be useful for taxonomic and evolutionary studies of different plant taxa. Bignonieae is the largest tribe of Bignoniaceae, composed mostly by woody climber species whose taxonomies are quite complicated. We reviewed and added new data concerning chromosome numbers

4. Efeito do etil-cianoacrilato (Super Bonder®) e do polidor líquido de baixa viscosidade (Biscover®) sobre biofilme de Candida albicans em resina acrílica para reembasamento / Effect of ethyl-cyanoacrylate (Super Bonder®) and a liquid polish of low viscosity (Biscover®) on Candida albicans biofilms on denture reline resin
The purpose of this study was to verify, using the confocal laser scanning microscopy (CLSM), if the use of a photoactivated resin of low viscosity (Biscover®) and a ethyl-cyanoacrylate (Super Bonder®) could be efficient in the prevention or reduction of Candida albicans biofilms. Fifty six reline resin specimens (New Truliner) were fabricated and randomly

5. CitogenÃtica em peixes de cabeceiras de dois riachos pertencentes à bacia do Alto rio ParanÃ, regiÃo de Toledo (PR) / Cytogenetic in fishes from two headwaters streams belonging to the Upper Paranà river basin, Toledo (PR)
Cytogenetics studies were carried out in two genera of fishes from Pindorama and Lopei streams, Upper Paranà River basin, with cytossistematic and ecologic-evolutionary approaches. In Heptapterus mustelinus, the first cytogenetics characterization in the genus was carried out, verifying 54 chromosomes (26m+18sm+4st+6a), which is a diploid number not observe

6. Bone regeneration in surgically created defects filled with autogenous bone: an epifluorescence microscopy analysis in rats
Although the search for the ideal bone substitute has been the focus of a large number of studies, autogenous bone is still the gold standard for the filling of defects caused by pathologies and traumas, and mainly, for alveolar ridge reconstruction, allowing the titanium implants installation. OBJECTIVES: The aim of this study was to evaluate the dynamics o

7. Cytogenetic analysis of Astylus antis (Perty, 1830) (Coleoptera, Melyridae): Karyotype, heterochromatin and location of ribosomal genes
Cytogenetic analysis of Astylus antis using mitotic and meiotic cells was performed to characterize the haploid and diploid numbers, sex determination system, chromosome morphology, constitutive heterochromatin distribution pattern and chromosomes carrying nucleolus organizer regions (NORs). Analysis of spermatogonial metaphase cells revealed the diploid num

8. Cytogenetic characterization of Partamona cupira (Hymenoptera, Apidae) by fluorochromes
Four colonies of the stingless bee Partamona cupira (Hymenoptera: Apidae) were cytogenetically analyzed using conventional staining and the fluorochromes CMA3 e DAPI. The females have 2n = 34 chromosomes (2K=32+2 Genetics and Molecular Biology. Publicado em: 02/04/2010

9. Cytogenetic study of two species of the family Pimelodidae (Siluriformes) collected in Lago Guaíba, Rio Grande do Sul, Brazil
Exemplares de Parapimelodus nigribarbis e Pimelodus maculatus coletados na bacia do rio Guaíba, Porto Alegre, Rio Grande do Sul, foram analisados citogeneticamente. As duas espécies apresentaram um número diplóide de 56 cromossomos, com P. nigribarbis mostrando um cariótipo de 20m + 20sm + 4st + 12a, NF igual a 100; e P. maculatus com 24m + 20sm + 6st +

10. Comparative cytogenetic analysis between Lonchorhina aurita and Trachops cirrhosus (Chiroptera, Phyllostomidae)
Phyllostomidae comprises the most diverse family of neotropical bats, its wide range of morphological features leading to uncertainty regarding phylogenetic relationships. Seeing that cytogenetics is one of the fields capable of providing support for currently adopted classifications through the use of several markers, a comparative analysis between two Phyl

11. Cytogenetic characterization of Melipona rufiventris Lepeletier 1836 and Melipona mondury Smith 1863 (Hymenoptera, Apidae) by C banding and fluorochromes staining
The stingless bees Melipona rufiventris and M. mondury were analyzed cytogenetically by conventional staining with Giemsa, C-banding and sequential staining with the fluorochromes CMA3/DA/DAPI. Both species presented 2n = 18 and n = 9, except for one colony of M. rufiventris, in which some individuals had 2n = 19 due to the presence of a B chromosome. After

12. AnÃlise citogÃnetica comparativa entre Glossophaga soricina, Platyrrhinus lineatus e Sturnira lilium (Phyllostomidae, Chiroptera)
Mitotic chromosomes of Glossophaga soricina (2n=32,XY; NF=60), Platyrrhinus lineatus and Sturnira lilium (2n=30,XY; NF=56) were analyzed through the conventional staining, C-banding, silver nitrate impregnation (AgNO3) and base-specific fluorochromes. Data of the conventional analysis obtained from the three species are in agreement with those described in t
