Benthic meiofauna as indicator of ecological changes in estuarine ecosystems: T...
Alves, Ana; Adão, Helena; Ferrero, T.J; Marques, J.C; Costa, Maria Jose; Patricio, J.a b s t r a c t Estuarine meiofauna communities have been only recently considered to be good indicators of ecological quality, exhibiting several advantages over macrofauna, such as their small size, high abundance, rapid generation times and absence of a planktonic phase. In estuaries we must account not only for a great natural variability along the estuarine gradient (e.g. sediment type and dynamics, oxygen...
Do nematode and macrofauna assemblages provide similar ecological assessment in...
Alves, Ana; Adão, Helena; Costa, Maria Jose; Marques, J.C.; Patricio, J.Do nematode and macrofauna assemblages provide similar ecological assessment information? To answer this question, in the summer of 2006, subtidal soft-bottom assemblages were sampled and environmental parameters were measured at seven stations covering the entire salinity gradient of the Mondego estuary. Principal components analysis (PCA) was performed on the environmental parameters, thus establishing differ...
Vitamina C restaura pressão arterial e a resposta vasodilatadora no antebraço e...
Fernandes,Pricilla Regina Oliveira Fernandes; Lira,Fabio Alexandre dos Santos; Borba,Vanessa Vieira Lopes; Costa,Maria José CarvalhoFUNDAMENTO: A resposta vasodilatadora periférica tem um papel importante na fisiopatologia da obesidade e das doenças cardíacas. OBJETIVO: Avaliar o efeito crônico da suplementação de vitamina C (VitC) sobre a pressão arterial e na resposta vasodilatadora ao estresse mental. MÉTODOS: Neste estudo prospectivo, randomizado e duplo cego foram avaliadas crianças obesas, de ambos os gêneros e com idade entre 8 a 12 ...
Effect of the daily consumption of ostrich and bovine meat on the lipid metabol...
Carvalho-Filho,Edvaldo Vasconcelos de; Costa,Maria José Carvalho da; Bion,Francisca Martins; Silva,João Andrade daThe objective of this study is to evaluate the effect of the daily consumption of ostrich meat (lliofemuralis internus) and bovine meat (Psoas major) on the lipid metabolism in adult mice. The analyses of the centesimal composition of the meats and preparation of the diets were accomplished following the recommendations of the American Institute of Nutrition-AIN-93. Three groups of 150 day-old animals: group I ...
Modulation of drug resistance in Staphylococcus aureus by extract of mango (Man...
Oliveira,Susy Mary Souto de; Falcão-Silva,Vivyanne S.; Siqueira-Junior,José P.; Costa,Maria José de Carvalho; Diniz,Margareth de Fátima F. de MeloIn an ongoing project to evaluate natural compounds isolated from by-products or wastes from vegetables and fruits (edible plants) as modulators of antibiotic resistance, ethanol extract from mango peel was investigated using Staphylococcus aureus strains possessing efflux mechanisms of resistance to norfloxacin, erythromycin and tetracycline. The minimum inhibitory concentrations (MIC) of the antibiotics were ...
Continued high prevalence of G2P[4] rotavirus strains in Belgium : vaccine indu...
Costa, Maria José Roque daDissertação de mestrado integrado em Engenharia Biomédica (área de especialização em Engenharia Clínica) ; Group A rotaviruses are the leading cause of severe diarrhoea in children under 5 years of age worldwide, accounting for approximately 600,000 child deaths each year. Two rotavirus vaccines, Rotarix® and RotaTeq®, have been licensed in Belgium, and they have strongly reduced the disease caused by rotaviru...
Trajetória de uma expressão amazônica : o encanto do desencanto em Florentina E...
Costa, Maria José da Silva MoraisDissertação (mestrado)—Universidade de Brasília, Instituto de Letras, Departamento de Teoria Literária e Literaturas, 2006. ; Este trabalho procura investigar a literatura de Florentina Esteves como um dos desaguadouros da herança ficcional da região amazônica, em especial a da expressão contística do Acre. Para tanto, antes de chegar à análise da prosa da autora, são observados textos de autores que adotara...
Diet and cancer in Northeast Brazil: evaluation of eating habits and food group...
Lima,Flávia Emília Leite de; Latorre,Maria do Rosário Dias de Oliveira; Costa,Maria José de Carvalho; Fisberg,Regina MaraA hospital-based case-control study was performed from August 2002 to November 2003 in Northeast Brazil. Eighty-nine women were recruited with histologically confirmed breast cancer (age 30-80 years), matched for age with 94 controls. Food consumption of cases and controls was evaluated by foods and food groups, categorized in consumption tertiles. Odds ratio (OR) and 95% confidence intervals (95%CI) were obtai...
Spatial distribution of subtidal Nematoda communities along the salinity gradie...
Adão, Helena; Alves, Ana Sofia; Patrício, Joana; Neto, João Magalhães; Costa, Maria José; Marques, João CarlosThis study investigated the spatial distribution of subtidal nematode communities along the salinity gradients of two Portuguese estuaries exposed to different degrees of anthropogenic stress: the Mira and the Mondego. The nematode communities were mainly composed of Sabatieria, Metachromadora, Daptonema, Anoplostoma, Sphaerolaimus and Terschellingia species, closely resembling the communities of Northern Europ...
Spatial distribution of subtidal meiofauna communities along a salinity gradien...
Alves, Ana; Adão, Helena; Patricio, J.; Neto, J. M.; Costa, Maria Jose; Marques, J.C.Global climate changes contribute to the occurrence of stronger and more frequent extreme events, which have unmistakable impact on temporal and spatial distribution patterns of benthic communities. The interest of studding benthic fauna response to extreme events is to obtain useful information on detecting which organisms better reflect ecological status of systems, and, on the other hand, to understand early...
