Dielectric properties of Al-Nb amorphous mixed oxides
Di Franco, F.; Santamaria, M.; Di Quarto, F.; La Mantia, F.; Sá, A. I. Correia de; Rangel, C. M.An impedance study of amorphous thin oxide films grown on sputtered Al-Nb alloys is presented. The characterization of the electronic properties of mixed amorphous oxide on the basis of the theory of amorphous semiconductor Schottky barrier has been carried out for anodic film on Al-92at.%Nb in a very detailed manner. The semiconductor to insulator transition of formed oxides as a function of the alloy composit...
Avaliação antropométrica de crianças no ensino pré-escolar da rede pública do m...
Monteiro, Clara; Franco, F.; Santos, A.; Neves, S.; Neves, AnaDada a crescente prevalência de perturbações alimentares em crianças e adolescentes, a avaliação nutricional e o conhecimento dos hábitos alimentares e do estilo de vida, são uma importante contribuição para o estabelecimento de estratégias de intervenção. O estudo realizado incidiu sobre crianças entre os 3 e os 6 anos do ensino pré-escolar da rede pública do Município da Azambuja, tendo-se realizado avaliaçõe...
Miocardiopatia de etiologia isquémica versus não-isquémica: haverá diferenças n...
Lourenço, C; Saraiva, F; Martins, H; Baptista, R; Costa, S; Coelho, L; Vieira, H; Monteiro, P; Franco, F; Gonçalves, L; Providência, LAINTRODUCTION: Previous studies have associated heart failure (HF) of ischemic etiology with worse prognosis compared to HF from non-ischemic cardiomyopathy. HF treatment has evolved significantly in recent years. Has this evolution had an impact on this prognostic gap? OBJECTIVE: The aim of our study was to compare patients with advanced HF--nonischemic versus ischemic etiology--in terms of baseline characteri...
Anemia: apenas marcador ou preditor independente de mortalidade na insuficiênci...
Saraiva, F; Martins, H; Costa, S; Franco, F; Gonçalves, L; Providência, LAINTRODUCTION AND OBJECTIVES: Advanced heart failure (HF) remains a major cause of mortality. Identification of new prognostic risk factors is therefore a priority. Anemia, a frequent comorbidity in HF patients and a recognized trigger of symptoms, has recently received considerable attention in this context. Several studies have demonstrated an association between anemia and increased mortality in stable chroni...
Transplantação cardíaca: cinco anos de actividade
Antunes, MJ; Prieto, D; Sola, E; Antunes, PE; Oliveira, JF; Franco, F; Providência, LAOBJECTIVE: To analyze the initial five years experience of the new heart transplant program of Coimbra University Hospitals. METHODS: Between November 2003 aid December 2008, 132 patients were transplanted, with a mean age of 52.0 years (range 3-71 years), of whom 98 were male (74%). Half of the patients had dilated cardiomyopathy and 33% ischemic cardiomyopathy. The mean age of donors was 31.7 years and 102 w...
Prognostic value of CA125 in advanced heart failure patients
Monteiro, S; Franco, F; Costa, S; Monteiro, P; Vieira, H; Coelho, L; Oliveira, L; Providência, LAINTRODUCTION: Serum levels of CA125 are often high in advanced heart failure (AHF) patients. AIM: To determine the predictive value of CA125 in forecasting the occurrence of death or cardiac transplantation in an AHF population. METHODS: 88 AHF patients referred for heart transplantation were divided into 2 groups based on CA125 levels: normal (CA125<38 U/mL) and elevated (>/=38 U/mL). Events (death or heart tr...
Cardiac allograft systolic function. Is the aetiology (ischaemic or idiopathic)...
Antunes, MJ; Biernet, M; Sola, E; Oliveira, L; Prieto, D; Franco, F; Providência, LAThe natural history of the LV systolic function (LV-SF) and functional capacity of survivors of heart transplantation (Htx) has not been defined. Some investigators suggest that SF may be different in recipients with different pre-transplant aetiologies: ischaemic or dilated, idiopathic disease. Routine transthoracic echocardiograms (TTE) were performed during a 1-year follow-up in 48 Htx recipients (total 864 ...
Impacto de uma consulta diferenciada de insuficiência cardíaca, na frequência d...
Correia, J; Franco, F; Roque, C; Vieira, H; Providência, LABACKGROUND: High rates of morbidity and mortality are observed in patients with advanced heart failure (AHF). AHF is now considered the most costly syndrome in cardiology owing to the substantial economic burden associated with hospitalizations for acute decompensation. A management program that involves specialized follow-up by a multidisciplinary team has been suggested as a desirable strategy for improving o...
Determination of myricetin derivatives in Chrysobalanus icaco L. (Chrysobalanac...
Barbosa,Wagner Luiz R.; Peres,Amiraldo; Gallori,Sandra; Vincieri,Franco F.The flavonoidic fraction composition of the hydroalcoholic extract of Chrysobalanus icaco L. (Chrysobalanaceae) leaves, which are largely used in the traditional medicine in Northern Brazil to control the glycaemia of diabetic patients, was characterised. Myricetin 3-O-glucuronide (miricitrin) and quercitrin, among other minor myricetin derivatives, were evidenced by HPLC/DAD and HPLC/MS analysis.
Hepatic UDP-glucose 13C isotopomers from [U-13C]glucose: a simple analysis by 1...
Antunes, MJ; Biernat, M; Sola, E; Oliveira, L; Prieto, D; Franco, F; Providência, LAMenthol glucuronide was isolated from the urine of a healthy 70-kg female subject following ingestion of 400 mg of peppermint oil and 6 g of 99% [U-(13)C]glucose. Glucuronide (13)C-excess enrichment levels were 4-6% and thus provided high signal-to-noise ratios (SNRs) for confident assignment of (13)C-(13)C spin-coupled multiplet components within each (13)C resonance by (13)C NMR. The [U-(13)C]glucuronide isot...
