25. Marcadores de proliferação celular no tumor venéreo transmissível canino transplantado
Cães machos, adultos, mestiços, foram transplantados com células do tumor venéreo transmissível canino (TVTC), na região hipogástrica. Foram coletados doze espécimes do TVTC, sendo metade durante a fase proliferativa e metade durante a fase regressiva. Fragmentos do tumor foram fixados em formol a 10%, tamponado e processado rotineiramente para micro

26. Estudo citogenético em híbridos naturais de Callithrix (Callitrichidae: Primatas) na Mata Atlântica do estado do Rio de Janeiro, Brasil
No estado do Rio de Janeiro, em área de Mata Atlântica, Callithrix aurita (É. Geoffroy in Humboldt, 1812) é a espécie nativa considerada vulnerável à extinção e C. jacchus (Linnaeus, 1758) e C. penicillata (É. Geoffroy, 1812) são espécies invasoras. As principais ameaças à espécie nativa são a degradação do habitat e a hibridação, embora

27. Histologic grading and nucleolar organizer regions in oral squamous cell carcinomas
OBJECTIVE: The purposes of this study were to histologically assess different types of oral squamous cell carcinoma and the silver-binding nucleolar organizer region (AgNOR) morphology in neoplastic cells, as well as to quantify the number of AgNORs in each type of carcinoma in order to relate AgNOR count and histologic grading. MATERIAL AND METHODS: Twenty-

28. A new karyotype of Wiedomys pyrrhorhinus (Rodentia: Sigmodontinae) from Chapada Diamantina, northeastern Brazil
A new karyotype of Wiedomys pyrrhorhinus (Wied, 1821) is described, including G- and C-banding and Ag-NOR sites from specimens collected in the municipality of Morro do Chapéu, situated in the northern region of the Chapada Diamantina, state of Bahia. Karyological studies of W. pyrrhorhinus have shown a constant diploid number (2n) of 62 with two different

29. Inflammatory response, parasite load and AgNOR expression in ear skin of symptomatic and asymptomatic Leishmania (Leishmania) chagasi infected dogs
The skin has an important role in the transmission of visceral leishmaniasis (VL) as the infection pathway in dogs. To better characterize the inflammatory response of intact skin in VL, sixty infected dogs (30 symptomatic and 30 asymptomatic) and six non-infected controls were studied. Diagnosis of visceral leishmaniasis was confirmed by RIFI and ELISA; dir

30. The karyotype of Adenomera diptyx (Boettger 1885) (Anura, Leptodactylidae) from northeastern Argentina
In this work we analyzed the karyotype of five populations of Adenomera diptyx from Argentina after conventional staining, Ag-NOR and C-banding. All specimens presented 2n = 26 and FN = 34. The karyotype was formed by three submetacentric, one metacentric and nine telocentric pairs. Silver staining revealed that the NOR was located on a secondary constrictio

31. Análise Citogenética de DNAr 18S, 5S e cromossomo B de Iheringichthys labrosus (Lütken, 1874) (Siluriformes, Pimelodidae)
Foram realizadas análises citogenéticas em Iheringichthys labrosus do Rio Tibagi, Paraná, Brasil com a localização cromossômica dos DNAs ribossômicos 18S e 5S e a composição de bases de seus cromossomos B. As AgNORs foram observadas em posição terminal, no braço longo de um par de cromossomos subtelocêntricos. Marcações CMA3 positivas foram ob

32. Description of the karyotype of Rhagomys rufescens Thomas, 1886 (Rodentia, Sigmodontinae) from Southern Brazil Atlantic forest
Rhagomys rufescens (Rodentia: Sigmodontinae) is an endemic species of the Atlantic forest from Southern and Southeastern Brazil. Some authors consider Rhagomys as part of the tribe Thomasomyini; but its phylogenetic relationships remain unclear. Chromosomal studies on eight specimens of Rhagomys rufescens revealed a diploid number of 2n = 36 and a number of

33. Cytogenetic analysis of three sea catfish species (Teleostei, Siluriformes, Ariidae) with the first report of Ag-NOR in this fish family
Despite their ecological and economical importance, fishes of the family Ariidae are still genetically and cytogenetically poorly studied. Among the 133 known species of ariids, only eight have been karyotyped. Cytogenetic analyses performed on Genidens barbus and Sciades herzbergii revealed that both species have 2n = 56 chromosomes and Cathorops aff. mapal

34. Karyological study of Amphisbaena ridleyi (Squamata, Amphisbaenidae), an endemic species of the Archipelago of Fernando de Noronha, Pernambuco, Brazil
The karyotype of Amphisbaena ridleyi, an endemic species of the archipelago of Fernando de Noronha, in State of Pernambuco, Brazil, is described after conventional staining, Ag-NOR impregnation and fluorescence in situ hybridization (FISH) with a telomeric probe. The diploid number is 46, with nine pairs of macrochromosomes (three metacentrics, four subteloc

35. Leucoplasias bucais: estudo comparativo entre o grau histológico de displasia, imunoexpressão de hMLH1 e p53 e análise quantitativa de AgNOR
hMLH1 is a protein of the mammalian mismatch repair system (MMR), which maintains genomic stability during repeated duplication. Investigations point to a role of hMLH1 in oral carcinogenesis, and its expression pattern may be related to epigenetic events and microsatellite instability in oral leukoplakias and squamous cell carcinomas. It seems that those al

36. Avaliação longitudinal do comportamento proliferativo da mucosa bucal de pacientes com leucoplasia por meio da citologia : relato de quatro casos
O objetivo do estudo foi avaliar a o comportamento celular proliferativo através da quantificação dos AgNOR em células descamadas da mucosa bucal adjacente e contralateral às lesões de pacientes com leucoplasia. O delineamento do estudo foi observacional, longitudinal, clínico com relação de associação e os achados foram apresentados como casos is
