Lesões Cáusticas do Tubo Digestivo Superior em Crianças. Experiência de 8 anos ...
Santos, Fátima; Costa, Miguel; Poças, F. Castro; Silva, C. Gomes; Saraiva, M. Mascarenhas; Allegro, Sollari; Pinho, Carlos; Valente, BaltazarA ingestão acidental de produtos cáusticos pelas crianças continua a ser um problema actual. Com o objectivo de conhecer a panorâmica dos últimos 8 anos, no Hospital Geral de Santo António (HGSA), os autores fizeram a revisão dos processos clínicos referentes às 88 crianças que deram entrada no Serviço de Urgência deste hospital, de Janeiro de 1988 a Dezembro de 1995, por ingestão de cáusticos e que motivou a r...
Orquestrar o aprender no ensino superior - Concepções, abordagens e experiência...
Chaleta, E.; Grácio, L.; Veiga Simão, A.; Ramalho, G.; Rosário, P.; Saraiva, M.; Sebastião, L.; Leal, F.; Silva, J.Nas últimas décadas o modelo SAL debruçou-se sobre três componentes fundamentais do processo de aprendizagem: concepções, abordagens e percepção sobre os contextos de aprendizagem. A partir das experiências descritas pelos estudantes, estes estudos revelaram a existência de relações entre as três componentes, a qualidade da aprendizagem e os resultados académicos (Entwistle 2007; Marton & Säljo, 1997; Chaleta e...
Improving visual attractiveness to enhance city-river integration - a methodolo...
Silva, J.B.; Saraiva, M.G.; Ramos, I.L.; Bernardo, F.The relationship between rivers and cities has evolved from a natural coexistence and interdependence to a progressive relationship of segregation and disintegration. This article uses a planning experiment to explore and discuss some concerns about visual attractiveness of city–river landscapes in promoting spatial integration of cities and rivers. It presents a methodological approach integrating expert opini...
The rs5743836 polymorphism in TLR9 confers a population-based increased risk of...
Carvalho, A; Cunha, C; Almeida, AJ; Osório, NS; Saraiva, M; Teixeira-Coelho, M; Pedreiro, S; Torrado, E; Domingues, N; Gomes-Alves, AG; Marques, ANon-Hodgkin lymphoma (NHL) has been associated with immunological defects, chronic inflammatory and autoimmune conditions. Given the link between immune dysfunction and NHL, genetic variants in toll-like receptors (TLRs) have been regarded as potential predictive factors of susceptibility to NHL. Adequate anti-tumoral responses are known to depend on TLR9 function, such that the use of its synthetic ligand is b...

Sequential injection analysis system with spectrophotometric detection for dete...
Rufino,José Luiz; Pezza,Helena Redigolo; Pezza,Leonardo; Pinto,Paula C. A. G.; Saraiva,M. Lúcia M. F. S.; Lima,José L. F. C.This work proposes a sequential injection analysis (SIA) system for the spectrophotometric determination of norfloxacin (NOR) and ciprofloxacin (CIP) in pharmaceutical formulations. The methodology was based on the reaction of these drugs with p-(dimethylamino)cinnamaldehyde in micellar medium, producing orange colored products (λmax = 495 nm). Beer´s law was obeyed in the concentration range from 2.75x10-...
Interaction between growth differentiation factor 9, insulin-like growth factor...
Martins,F.S.; Celestino,J.J.H.; Saraiva,M.V.A.; Chaves,R.N.; Rossetto,R.; Silva,C.M.G.; Lima-Verde,I.B.; Lopes,C.A.P.; Campello,C.C.; Figueiredo,J.R.The objective of this study was to determine the effects of GDF-9, IGF-I, and GH alone or combined on preantral follicle survival, activation and development after 1 and 7 days of in vitro culture. Either fresh (non-cultured) or cultured ovarian tissue was processed for histological and fluorescence analysis. For all media tested, the percent of normal follicles was greater when compared to minimum essential me...
The importance of ultrasound findings in the study of anal pain
Vieira, A.; Castro-Poças, F.; Lago, P.; Pimentel, R.; Pinto, R.; Saraiva, M.; Areias, J.ABSTRACT Objective: endoanal ultrasonography can detect organic causes of anal pain without pathology on physical examination. The aim of this study is to evaluate the importance of endoanal ultrasonography in the diagnosis and therapeutic management of idiopathic and functional anal pain. Material and methods: retrospective study, between 15 March 2005 and 15 June 2008, of all patients with proctalgia and norm...
Evaluation of Bone Remodeling in Hemodialysis Patients: Serum Biochemistry, Cir...
Ferreira, A; Saraiva, M; Behets, G; Macedo, A; Galvão, M; Haese, P; Drüeke, TBACKGROUND: To optimize the noninvasive evaluation of bone remodeling, we evaluated, besides routine serum markers, serum levels of several cytokines involved in bone turnover. METHODS: A transiliac bone biopsy was performed in 47 hemodialysis patients. Serum levels of intact parathyroid hormone (iPTH; 1-84), total alkaline phosphatases (tAP), calcium, phosphate and aluminum (Al) were measured. Circulating lev...
Determination of metoprolol, acebutolol and propranolol in pharmaceutical formu...
Passos,Marieta L. C.; Saraiva,M. Lúcia M. F. S.; Lima,José L. F. C.; Korn,M. Graças A.A mechanized system for the determination of beta-blockers in pharmaceutical formulations is presented. Using the Sequential Injection Analysis (SIA) technique it was achieved a simple, economical and versatile methodology adaptable to any pharmaceutical control involving these substances. It does not require any pre-treatment for the samples, as they must only be dissolved in acid before analysis. Linear calib...
