Intervenção PRAdA: Efeitos no Peso Induzidos por Proposta de Alteração de Compo...
Peixoto, Catarina; Unidade de Epidemiologia. Instituto de Medicina Preventiva. Faculdade de Medicina de Lisboa. Lisboa. Portugal.Introdução: Perdas de peso melhoram o controlo da tensão arterial em indivíduos hipertensos. As intervenções comportamentais para a perda de peso parecem ser menos eficazes nos imigrantes de origem africana (IOA). Os principais objetivos foram avaliar os efeitos no peso de uma intervenção alimentar em hipertensos nativos de origem portugueses (NOP) e IOA; identificar fatores de sucesso na perda de peso; avaliar...

Peixoto, Catarina; Carrilho, Gisela; Alarcão, Violeta; Guerra, Filipa; Simões, Rui; Fernandes, Milene; Nicola, Paulo; Guiomar, Sofia; Nogueira, Paulo© Creative Commons Attribution-NonCommercial-NoDerivs 3.0 Portugal License. ; Introduction: Blood pressure is significantly improved with weight loss. Behavioral interventions for weight loss seem to be less successful in African immigrants. Our main aims were to assess the effect of a dietary and lifestyle intervention on weight among hypertensive Portuguese natives and immigrants and to identify success fact...

Framework estatístico de um modelo nacional de avaliação em saúde
Simões, Rui Pedro RaminhosTese de mestrado em Bioestatística, apresentada à Universidade de Lisboa, através da Faculdade de Ciências, 2011 ; O presente estudo esta inserido no projeto SINAS (Sistema Nacional de Avaliação em Saúde), que esta a ser desenvolvido para a Entidade Reguladora da Saúde, pelo consorcio Siemens, S.A. – Joint Commission International, e tem como principal objetivo a implementação de um framework estatístico que s...
A Relational Learning approach to Structure-Activity Relationships in Drug Desi...
Rui Camacho; Max Pereira; Vítor Santos Costa; Nuno Foseca; Carlos Adriano; Carlos Simões; Rui BritoIt has been recognized that the development of new therapeutic drugs is a complex and expensive process. A large number of factors affect the activity in vivo of putative candidate molecules and the propensity for causing adverse and toxic effects is recognized as one of the major hurdles behind the current "target-rich, lead-poor" scenario. Structure-Activity Relationship (SAR) studies, using relational Machin...
Calibration of model parameters for the cyclic response of end-plate beam-to-co...
Nogueiro, Pedro; Silva, Luís Simões da; Bento, Rita; Simões, RuiComposite joints, considering the composite action of steel and concrete, exhibit, in general, high strength and high ductility. As a consequence, the use of this type of joint has been increasing in many countries, especially in those that are located in earthquake-prone regions. In this paper, a hysteretic model with pinching is presented that is able to reproduce the cyclic response of steel and composite jo...
An iron-based T1 contrast agent made of iron-phosphate complexes: In vitro and ...
Rodríguez, Elisenda; Simoes, Rui; Roig, Anna; Molins, Elies; Nedelko, Nataliya; Slawska-Waniewska, Anna; Aime, Silvio; Arús, Carles; Cabañas, MiquelAbstract A new iron-based T 1 contrast agent consisting of a complex of iron ions coordinated to phosphate and amine ligands (Fe(phos) in short) has been characterized by spectroscopic and magnetic measurements. NMR relaxation studies showed r 1 values to be dependent on the phosphate salt concentration, K2HPO4, present in the medium. r 1 reaches a maximum value of 2.5 mM-1 s-1 for measurements carried out at ...
Numerical implementation and calibration of a hysteretic model with pinchin...
Nogueiro, Pedro; Silva, Luís Simões da; Bento, Rita; Simões, RuiIn this paper, a hysteretic model with pinching is presented that is able to reproduce realistically the cyclic response of generic steel joints. Secondly, the computer implementation and adaptation of the model in a spring element within the computer code SeismoStruct is described. The model is subsequently calibrated using a series of experimental test results for steel joints subjected to cyclic loading. Fin...
Experimental behaviour of standardised European end plate beam-to-column stel j...
Nogueiro, Pedro; Silva, Luís Simões da; Bento, Rita; Simões, RuiThis work presents the results of the study of the six experimental tests of standardised end-plate beam-to-column steel joints under arbitrary cyclic loading. The experimental programme is divided into two groups, varying the column section size. Each group has the first monotonic test and two more cyclic tests with arbitrary loading. The results are presented in terms of M-Ø curves, main mechanical joint prop...
