Estudo dos Casos de Ameloblastomas Diagnosticados no Laboratório de Patologia Bucal da Faculdade de Odontologia da Universidade Federal do Rio Grande do Sul

Abstract

Com o objetivo de obter um perfil de indivíduos afetados por ameloblastoma e comparar os resultados com os estudos encontrados na literatura, realizou-se uma análise retrospectiva dos casos de ameloblastomas do Laboratório de Patologia Bucal da FO-UFRGS. Os resultados revelaram uma maior ocorrência em indivíduos jovens, do sexo feminino, raça branca, localização predominantemente na mandíbula e tipo histológico plexiforme. Conclui-se que, o perfil dos pacientes com ameloblastoma diagnosticados no Laboratório de Patologia Bucal da FO-UFRGS concorda com o perfil de pacientes com ameloblastoma diagnosticado em outras partes do mundo e relatado na literatura, diferindo apenas no que se refere a faixa etária no momento do diagnóstico.

A new species of Hyphessobrycon Durbin from northeastern Brazil: evidence from morphological data and DNA barcoding (Characiformes, Characidae)

“…Pristella maxillaris (Ulrey, 1894) is the sister-group of the Hyphessobrycon sensu stricto (Carvalho 2011), and corroborated in our analysis (Figure 6). …”

“…One such case is the Hyphessobrycon sensu stricto as defined by Carvalho (2011) and Cavalho and Malabarba (2015). According to those authors, this group is composed by approximately 25 species.…”

“…Among the species considered by Weitzman and Palmer (1997) as possibly related to the “rosy tetra clade”, only H. hasemani and H. pulchripinnis were considered to belong to Hyphessobrycon sensu stricto (Carvalho 2011, Carvalho and Malabarba 2015). Pristella maxillaris (Ulrey, 1894) is the sister-group of the Hyphessobrycon sensu stricto (Carvalho 2011), and corroborated in our analysis (Figure 6).…”

“…The morphological data was based on both examined material (see Comparative material examined) and the literature (e.g., Géry 1977, Géry and Uj 1987, Costa and Géry 1994, Plaquete et al 1996, Weitzman and Palmer 1997, Zarske 2008, Hein 2009, Carvalho 2011, Lima et al 2013, Zarske 2014, Carvalho and Malabarba 2015, Carvalho et al 2017). The data obtained by this method are presented in the diagnosis section of results.…”

“…After that, Carvalho (2011) and Carvalho and Malabarba (2015) proposed the group named Hyphessobrycon sensu stricto , diagnosed by the position of Weberian apparatus upward horizontal through dorsal margin of operculum, presence of a black blotch on dorsal fin and the absence of a midlateral black stripe on body, with a more restricted composition than the “rosy tetra clade” sensu Weitzman and Palmer (1997), comprising: H. compressus (Meek, 1904), H. bentosi Durbin, 1908, H. copelandi Durbin, 1908, H. epicharis Weitzman & Palmer, 1997, H. eques (Steindachner, 1882), H. erythrostigma (Fowler, 1943), H. georgettae Géry, 1961, H. haraldschultzi Travassos, 1960, H. hasemani Fowler, 1913, H. khardinae Zarske, 2008, H. megalopterus (Eigenmann, 1915), H. micropterus (Eigenmann, 1915), H. minor Durbin, 1909, H. pulchripinnis Ahl, 1937, H. pyrrhonotus Burgess, 1993, H. rosaceus Durbin, 1909, H. roseus (Géry, 1960), H. simulatus (Géry, 1960), H. socolofi Weitzman, 1977, H. sweglesi (Géry, 1961), H. takasei Géry, 1964 and H. werneri Géry & Uj, 1987. Other species recently referred to the “rosy tetra clade” such as Hyphessobrycon dorsalis Zarske, 2014, H. jackrobertsi Zarske, 2014, H. paepkei Zarske, 2014 and H. pando Hein, 2009 share these traits, but their taxonomic status is uncertain (Carvalho and Malabarba 2015).…”
