Journal ArticleDOI
Metabolic Biomarkers of Prenatal Disorders: An Exploratory NMR Metabonomics Study of Second Trimester Maternal Urine and Blood Plasma
Sílvia O. Diaz,Joana Pinto,Gonçalo Graça,Iola F. Duarte,António S. Barros,Eulália Galhano,Cristina Pita,Maria do Céu Almeida,Brian J. Goodfellow,Isabel M. Carreira,Ana M. Gil +10 more
TL;DR: Results show that NMR metabonomics of maternal biofluids enables the noninvasive detection of metabolic changes associated to prenatal disorders, thus unveiling potential disorder biomarkers.
Journal ArticleDOI
Human plasma stability during handling and storage: impact on NMR metabolomics
Joana Pinto,M. Rosário M. Domingues,Eulália Galhano,Cristina Pita,Maria do Céu Almeida,Isabel M. Carreira,Ana M. Gil +6 more
TL;DR: The comparison between heparin and EDTA anti-coagulant collection tubes, the former showed no interference of the polysaccharide, while conserving full spectral information, and the impact of long-term -80 °C storage was found almost negligible.
Journal ArticleDOI
Impact of prenatal disorders on the metabolic profile of second trimester amniotic fluid: a nuclear magnetic resonance metabonomic study.
Gonçalo Graça,Iola F. Duarte,António S. Barros,Brian J. Goodfellow,Sílvia O. Diaz,Joana Pinto,Isabel M. Carreira,Eulália Galhano,Cristina Pita,Ana M. Gil +9 more
TL;DR: Fetal malformations were found to have the highest impact on AF metabolite composition, enabling statistical validation to be achieved by several multivariate analytical tools, and newly found changes suggest possible additional effects on protein and nucleotide sugar biosynthesis.
Journal ArticleDOI
Absorption and metabolism of olive oil secoiridoids in the small intestine
Joana Pinto,Fátima Paiva-Martins,Giulia Corona,Edward S. Debnam,Maria Jose Oruna-Concha,David Vauzour,Michael H. Gordon,Jeremy P. E. Spencer +7 more
TL;DR: It is suggested that the reduced and glucuronidated forms represent novel physiological metabolites of the secoiridoids that should be pursued in vivo and investigated for their biological activity.
Journal ArticleDOI
Tolerance of Venerupis philippinarum to salinity: Osmotic and metabolic aspects
Vanessa Carregosa,Etelvina Figueira,Ana M. Gil,Sara Pereira,Joana Pinto,Amadeu M.V.M. Soares,Rosa Freitas +6 more
TL;DR: How clam Venerupis philippinarum copes with salinity changes and, hence biochemical and metabolomic alterations, taking place in individuals submitted to a wide range of salinities were investigated are investigated.
