A difusão das revistas científicas: os padrões de avaliação do ISI, Scielo e La...
Guerreiro, Rita Catarina MendesPassados mais de trezentos anos desde o aparecimento da primeira revista científica, a sua existência torna-se cada vez mais importante para a ciência, constituindo em muitas áreas o meio formal para a transmissão da ciência no seio da comunidade científica. Com esta dissertação pretendeu-se demonstrar os passos necessários para promover uma difusão eficaz das revistas científicas através da normalização e pos...

Genetic Variability in CLU and Its Association with Alzheimer's Disease
Guerreiro, Rita J.; Beck, John; Gibbs, J. Raphael; Santana, Isabel; Rossor, Martin N.; Schott, Jonathan M.; Nalls, Michael A.; Ribeiro, HelenaRecently, two large genome wide association studies in Alzheimer disease (AD) have identified variants in three different genes (CLU, PICALM and CR1) as being associated with the risk of developing AD. The strongest association was reported for an intronic single nucleotide polymorphism (SNP) in CLU. To further characterize this association we have sequenced the coding region of this gene in a total of 495 A...
Genetic screening of Alzheimer's disease genes in Iberian and African samples y...
Guerreiro, Rita João; Baquero, Miquel; Blesa, Rafael; Boada, Mercè; Brás, José Miguel; Bullido, Maria. J.; Calado, Ana; Crook, Richard; Ferreira, CarlaMutations in three genes (PSEN1, PSEN2, and APP) have been identified in patients with early-onset (<65years) Alzheimer’s disease (AD). We performed a screening for mutations in the coding regions of presenilins, as well as exons 16 and 17 of the APP gene in a total of 231 patients from the Iberian peninsular with a clinical diagnosis of early onset AD (mean age at onset of 52.9 years; range 31– 64). We found t...

Eficiência energética na administração do Porto de Sines
Guerreiro, Rita FernandesDissertação apresentada na Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa para a obtenção do grau de Mestre em Engenharia do Ambiente, perfil Gestão e Sistemas Ambientais ; A problemática energética é actualmente uma questão dominante nas agendas mundiais. A dependência de fontes de energia externas é uma realidade e compete aos governos e organizações mudar este paradigma, apostando na efic...
Complete screening for glucocerebrosidase mutations in Parkinson disease patien...
Brás, José; Paisan-Ruiz, Coro; Guerreiro, Rita; Ribeiro, Maria Helena; Morgadinho, Ana; Januário, Cristina; Sidransky, Ellen; Oliveira, CatarinaMutations in the gene encoding beta-glucocerebrosidase, a lysosomal degrading enzyme, have recently been associated with the development of Parkinson disease. ; http://www.sciencedirect.com/science/article/B6T09-4RDB8NT-4/1/f950a1008e7a0869f9c1b72f485255a4
Analysis of Parkinson disease patients from Portugal for mutations in SNCA, PRK...
Brás, José; Guerreiro, Rita; Ribeiro, Maria; Morgadinho, Ana; Januario, Cristina; Dias, Margarida; Calado, Ana; Semedo, Cristina; Oliveira, CatarinaBackground: Mutations in the genes PRKN and LRRK2 are the most frequent known genetic lesions among Parkinson's disease patients. We have previously reported that in the Portuguese population the LRRK2 c.6055G > A; p.G2019S mutation has one of the highest frequencies in Europe. Methods: Here, we follow up on those results, screening not only LRRK2, but also PRKN, SNCA and PINK1 in a cohort of early-onset and la...
Association of HFE common mutations with Parkinson's disease, Alzheimer's disea...
Guerreiro, Rita J.; Brás, José M.; Santana, Isabel; Januário, Cristina; Santiago, Beatriz; Morgadinho, Ana S.; Ribeiro, Maria H.; Hardy, JohnBackground: Pathological brain iron deposition has been implicated as a source of neurotoxic reactive oxygen species in Alzheimer (AD) and Parkinson diseases (PD). Iron metabolism is associated with the gene hemochromatosis (HFE Human genome nomenclature committee ID:4886), and mutations in HFE are a cause of the iron mismetabolism disease, hemochromatosis. Several reports have tested the association of HFE var...
G2019S dardarin substitution is a common cause of Parkinson's disease in a Port...
Brás, José Miguel; Guerreiro, Rita João; Ribeiro, Maria Helena; Januário, Cristina; Morgadinho, Ana; Oliveira, Catarina Resende; Cunha, LuísLRRK2 mutations have recently been described in families with Parkinson's disease. Here we show that one of them (G2019S) is present in 6% (7 of 124) unrelated cases of disease in a clinic-based sample series from central Portugal, but not present in 126 controls from the same population. Thus, LRRK2 mutations appear to be a common cause of typical Parkinson's disease and as such will alter clinical practice. ©...
