Relações filogenéticas em raias (Dasyatis, elasmobranchii) do estado do Ceará, ...
Vaz, Letícia de Almeida Leão; Carreiro, Carlos Riedel Porto; Goulart Filho, Luiz Ricardo; Furtado Neto, Manuel Antonio A.Stingrays of the genus Dasyatis can be found in all tropical seas, and are considered as the most exploited fishing resources among the elasmobranchs. The goal of this study was to identify the phylogenetic relationships among four Dasyatis species (D. americana, D. guttata, D. centroura e D. marianae), which stand out in the small-scale fisheries of Ceará State, Brazil. Tissue samples were collected from those...
Identification and analysis of seven effector protein families with different a...
Assis, Renata de Almeida Barbosa; Polloni, Lorraine Cristina; Patané, José Salvatore Leister; Thakur, Shalabh; Felestrino, Érica BarbosaThe Xanthomonadaceae family consists of species of non-pathogenic and pathogenic γ-proteobacteria that infect different hosts, including humans and plants. In this study, we performed a comparative analysis using 69 fully sequenced genomes belonging to this family, with a focus on identifying proteins enriched in phytopathogens that could explain the lifestyle and the ability to infect plants. Using a computati...
Contributions of cytogenetics to cancer research
Oliveira-Junior, Robson José de; Goulart Filho, Luiz Ricardo; Bastos, Luciana Machado; Alves, Dhiego de Deus; Silva, Sabrina Vaz dos Santos eThe two conflicting visions of tumorigenesis that are widely discussed are the gene-mutation hypothesis and the aneuploidy hypothesis. In this review we will summarize the contributions of cytogenetics in the study of cancer cells and propose a hypothetical model to explain the influence of cytogenetic events in carcinogenesis, emphasizing the role of aneuploidy. The gene mutation hypothesis states that gene-sp...

Frequencias genotipicas e alelicas do gene do polimorfismo da ECA I/D na popula...
Inacio, Juarez; Goulart Filho, Luiz Ricardo; Vieira, Gismar SilvaA alta incidência de doenças cardiovasculares e o sucesso no tratamento de pacientes infartados, através do uso de inibidores da enzima conversora da angiotensina (ECA), intensificaram os estudos que objetivaram determinar uma associação entre o gene da ECA e o infarto agudo do miocárdio (IAM). A prévia identificação de uma provável associação do polimorfismo I/D do gene da ECA ao IAM é a principal justificativ...
