Structure, growth and production of a remarkably abundant population of the com...

Souza, A. T.; Dias, E.; Campos, J.; Marques, J. C.; Martins, I.

The common goby, Pomatoschistus microps, is a relevant species from estuarine food webs, playing important roles as predator of polychaetes and crustaceans and as prey for larger fishes and crustaceans. The Minho estuary (NW Portugal) is a relatively wellpreserved and productive system. To assess the population structure and production of P. microps in this estuary, monthly samples were undertaken in three diff...


Routine screening of harmful microorganisms in beach sands: implications to pub...

Sabino, Raquel; Rodrigues, R.; Costa, I.; Carneiro, C.; Cunha, M.; Duarte, A.; Faria, N.; Ferreira, F. C.; Gargaté, M. J.; Júlio, C.; Martins, M. L.

Beaches worldwide provide recreational opportunities to hundreds of millions of people and serve as important components of coastal economies. Beach water is often monitored for microbiological quality to detect the presence of indicators of human sewage contamination so as to prevent public health outbreaks associated with water contact. However, growing evidence suggests that beach sand can harbor microbes ha...

Castro, C. C.; Martins, Rui C.; Teixeira, J. A.; Ferreira, António C.

Abstract Metabolomics aims at gathering the maximum amount of metabolic information for a total interpretation of biological systems. A process analytical technology pipeline, combining gas chromatography�mass spectrometry data preprocessing with multivariate analysis, was applied to a Port wine �forced ageing� process under different oxygen saturation regimes at 60 �C. It was found that extreme �forced ageing�...

Molecular evaluation of some Amanita ponderosa and fungal strains living in ass...

Salvador, C; Martins, M Rosário; Arteiro, J M; Caldeira, A Teresa

Amanita ponderosa are wild edible mushrooms that grow only in some microclimates, particularly those in the southwestern part of the Iberian Peninsula. Due to the vast diversity of mushrooms in nature, as well as nutrient variability, which is highly dependent on soil type and environmental conditions, it is essential to be able to characterize fungal microbiota that lives in association with mushrooms and to d...


Hahn's symmetric quantum variational calculus

Brito da Cruz, A. M. C.; Martins, N.; Torres, D. F. M.

We introduce and develop the Hahn symmetric quantum calculus with applications to the calculus of variations. Namely, we obtain a necessary optimality condition of Euler{Lagrange type and a sufficient optimality condi- tion for variational problems within the context of Hahn's symmetric calculus. Moreover, we show the effectiveness of Leitmann's direct method when applied to Hahn's symmetric variational calculu...


Liver Transplantation Prevents Progressive Neurological Impairment in Argininemia

Santos-Silva, E.; Cardoso, M.; Vilarinho, L.; Medina, M.; Barbot, C.; Martins, E.

Argininemia is a rare hereditary disease due to a deficiency of hepatic arginase, which is the last enzyme of the urea cycle and hydrolyzes arginine to ornithine and urea. The onset of the disease is usually in childhood, and clinical manifestations include progressive spastic paraparesis and mental retardation. Liver involvement is less frequent and usually not as severe as observed in other UCDs. For this rea...

Ramalho, M; Vaz, F; Coutinho, I; Pedrosa, C; Martins, A; Kaku, P; Esperancinha, F

Introdução: A Síndrome de Apneia Obstrutiva do Sono (SAOS) tem sido associada a uma diminuição da espessura da camada de fibras nervosas (CFN) e como possível fator de risco no desenvolvimento de Glaucoma. Este estudo pretende avaliar a relação entre a gravidade da SAOS e a espessura da CFN determinada por Tomografia de Coerência Óptica (OCT). Material e Métodos: Neste estudo prospetivo foram incluídos 47 olhos...


Assessment of sediment contamination in an impacted estuary: differential effec...

Costa, Pedro M.; Gonçalves, C.; Martins, M.; Rodrigo, A.; Carreira, S.; Costa, M. H.; Caeiro, Sandra

Conferência realizada em Lisboa, de 6-9 November de 2013 ; Estuarine pollution is reflected in the concentration of toxicants in sediments, depending on their geochemical properties, since sediments trap substances from the water column, either dissolved or bound to suspended matter. However, determining risk of sediment contaminants to biota has many constraints. For such reason, integrative approaches are ke...
