Serum Zn Levels in Dysphagic Patients Who Underwent Endoscopic Gastrostomy for ...
Santos, C; Fonseca, J; Brito, J; Fernandes, T; Gonçalves, L; Sousa Guerreiro, ABackground and aims: Dysphagic patients who underwent endoscopic gastrostomy (PEG) usually present protein-energy malnutrition, but little is known about micronutrient malnutrition. The aim of the present study was the evaluation of serum zinc in patients who underwent endoscopic gastrostomy and its relationship with serum proteins, whole blood zinc, and the nature of underlying disorder. Methods: From patients...
Structural features of electrodeposited copper electrodes for CO2 conversion
Machado, A. S. Reis; Fernandes, T. R. C.; Pardal, T.; Rangel, C. M.Direct electrochemical reduction of CO2 is a process that could contribute to the reduction of the emission of greenhouse gases by using CO2 as a raw material for fuel production. This paper focuses on voltammetric studies of functionalized electrodes for the electrochemical conversion of CO2 and reports on its use as a tool for electrode screening and optimization. Nickel substrates modified with copper and ru...
Conversion of carbon dioxide into fuel by electrochemical reduction in aqueous ...
Pardal, T.; Fernandes, T. R. C.; Machado, A. S. Reis; Rangel, C. M.he mission of Omnidea, a Portuguese SME is to perform leading edge R&D in innovative energy concepts. In collaboration with Research Institutes Omnidea is developing a technology based upon a regenerative energy storage cycle. In this cycle the recharge system converts CO2 into hydrocarbons using a renewable source of power. The discharge system produces electrical energy when hydrocarbons and oxygen from the r...
A survey on genetically modified maize in foods commercialised in Portugal
Fernandes, T.; Amaral, J.S.; Oliveira, M.B.P.P.; Mafra, I.Maize, the second most important genetically modified (GM) crop, has the highest number of authorised GM events for food and feed in the EU. To provide consumer’s information, labelling for food products containing more than 0.9% of GM material is demanded by the actual EU legislation. Analysis of foods is then essential to detect and quantify GM maize material and verify the compliance with labelling informati...
Knowledge-based entrepreneurship and employment growth in Portugal
Mamede, R.; Fernandes, T.In this paper we try to assess the direct impact of knowledge-based entrepreneurship (understood as the creation of new firms that intensively rely on more educated workers) on net changes in employment at both the economy and the industry levels. Based on a descriptive analysis, we show that new knowledge-based firms (KBF) differentiate themselves from other firms (new or not new) by having a positive direct c...
Fratura de patela com ruptura do tendão patelar em um cão: relato de caso
Filgueira,F.G.F; Azevedo,A. S; Fernandes,T.H.T; Nunes,G.D.L; Palmeira,R.B; Araújo,B.M; Carneiro,R.S; Nóbrega Neto,P.I; Sá,M.J.CRelatou-se a ocorrência de fratura patelar associada à ruptura do tendão patelar em um cão sem raça definida, macho, atendido em um hospital veterinário escola. A técnica utilizada foi a combinação de fixação óssea com fio de Kirschner e aplicação de banda de tensão, recomendada em fraturas transversais da patela. Para reparar a lesão do tendão patelar, realizou-se a sutura tipo Kessler modificada com fio de ná...
Desinserção proximal do músculo sartório na correção da luxação patelar medial ...
Tudury,E.A; Figueiredo,M.L; Kemper,B; Araújo,F.P; Chioratto,R; Marques,N.B; Fernandes,T.H.TSix surgical corrections were performed with techniques of bone and soft tissue reconstruction, according to the individual presentation of each patient, in four Toy breed dogs, which had grades III and IV luxation, two of them bilaterally operated. During the recovery excessive medial tension associated to the Sartorius muscle was detected, which motivated its release at the iliac insertion. The animals had a ...
Modified electrodes for electrochemical reduction of carbon dioxide
Machado, A. S. Reis; Fernandes, T. R. C.; Pardal, T.; Rangel, C. M.The efforts to constrain greenhouse gas emissions and concerns over security of fossil fuels have led to increased attention for renewable energy for the past decade. Renewable energy is one of the key solutions to the actual energy challenges. Omnidea in collaboration with Research Institutes is developing a technology based upon a regenerative energy storage cycle that could be a contribution to a low-carbon ...
Scale-up of a system for hydrocarbon production by electrochemical reduction of...
Fernandes, T. R. C.; Machado, A. S. Reis; Condeço, J.; Rangel, C. M.; Pardal, T.This work addresses the scaling up of a system for electrochemical reduction of CO2 to produce hydrocarbons that can be used as fuel for a regenerative energy storage cycle. Challenges involved in such a task are mentioned. Scalingup results of a system based on electrodes of high surface area with modified copper deposits are described. Current densities around 100 mA/cm2 were obtained. This corresponds to the...
Effect of carotid and aortic baroreceptors on cardiopulmonary reflex: the role ...
Fernandes,T.L.; Piratello,A.C.; Farah,V.; Fiorino,P.; Moreira,E.D.; Irigoyen,M.C.; Krieger,E.M.We determined the sympathetic and parasympathetic control of heart rate (HR) and the sensitivity of the cardiopulmonary receptors after selective carotid and aortic denervation. We also investigated the participation of the autonomic nervous system in the Bezold-Jarish reflex after selective removal of aortic and carotid baroreceptors. Male Wistar rats (220-270 g) were divided into three groups: control (CG, N ...
