Patterns of mitochondrial DNA damage in blood and brain tissues of a transgenic...
Kazachkova, Nadiya; Raposo, Mafalda; Montiel, Rafael; Cymbron, Teresa; Bettencourt, Conceição; Fernandes, Anabela Silva; Silva, Sara Carina Duarte daBACKGROUND: Machado-Joseph disease (MJD) is an autosomal dominant spinocerebellar ataxia caused by a CAG tract expansions in the ATXN3 gene. Patterns of mitochondrial damage associated with pathological findings of brain tissues could provide molecular biomarkers of this disorder. OBJECTIVE: The potential of mitochondrial DNA (mtDNA) damage as a biomarker of MJD progression was investigated using a transgeni...
Morphometry of the epidermis of an invasive megascoelecid earthworm (Amynthas g...
Cunha, Luís; Campos, Itxaso; Montiel, Rafael; Rodrigues, Armindo; Morgan, AndrewCopyright (c) 2010 Elsevier Inc. All rights reserved. ; For the first time, the structure, dimensions, and composition of the epidermis of an invasive earthworm species that has successfully colonized hostile conditions in actively volcanic soil on Sao Miguel (Azores) have been measured. Metal concentrations in actively volcanic (Furnas) and volcanically inactive(Fajã) soils were similar; however, Furnas soil...
Peopling, demographic history and genetic structure of the Azores Islands: Inte...
Santos, Cristina; Montiel, Rafael; Bettencourt, Conceição; Prata, M. João; Abade, Augusto; Aluja, M. Pilar; Lima, ManuelaWe have conducted studies to assess the variability of mtDNA and Y-chromosome markers in the Azores Islands (Portugal) and found that, for both genetic systems, the Azores, as a whole, fit well into the pattern of variation described for other Western European populations. Phylogeographic analysis of mitochondrial DNA (mtDNA) showed a major contribution from Mainland Portugal, as well as evidences of influxes f...
Polymorphism of the ApoE locus in the Azores Islands (Portugal)
Bettencourt, Conceição; Montiel, Rafael; Santos, Cristina; Pavão, Maria Leonor; Viegas-Crespo, Ana Maria; Lopes, Paula Alexandra; Lima, ManuelaAbstract de Comunicação em painel (P1088) apresentada em "European Human Genetics Conference 2006", 6-9 de Maio de 2006, Amsterdão, Holanda. ; The aim of this work was to report on the polymorphism of the ApoE locus in the Azores Islands (Portugal) in order to get insights on the genetic background that influences the lipid profile in this population, ascertained as considerably high in a preliminary study of ...
Polymorphism of the APOE locus in the Azores Islands (Portugal)
Bettencourt, Conceição; Montiel, Rafael; Santos, Cristina; Pavão, Maria Leonor; Viegas-Crespo, Ana Maria; Lopes, Paula Alexandra; Lima, ManuelaReproduced with permission of the copyright owner. Further reproduction prohibited without permission. ; Our aim in this study is to report on the polymorphism of the APOE gene in the Azores Islands (Portugal) to obtain a population baseline of the existing variation in this locus, known to be one of the genetic determinants of plasma lipid levels. One hundred twenty-six Azorean individuals were typed for the ...
Recolha de amostras de solo nas ilhas do Pico e Faial para isolamento de bactér...
Montiel, Rafael; Nascimento, Gisela; Ferreira, RicardoXII Expedição Científica do Departamento de Biologia - Pico 2005. ; Durante a Expedição Científica PICO 2005 recolheram-se oitenta e sete amostras de solo na Ilha do Pico e dezassete no Faial a diferentes altitudes e com diversos cobertos vegetais que foram transportadas para o laboratório de Entomopatologia para isolamento de bactérias e nemátodes entomopatogénicos. Todas as amostras já foram analisadas pelo ...
