Abordagem da má evolução ponderal
Tavares, M.; Matos, I.; Bandeira, A.; Guedes, M.RESUMO Introdução: A má evolução ponderal encontra-se entre um dos motivos mais frequentes de referenciação à consulta de Pediatria. As dificuldades encontradas na definição desta entidade e as diferentes abordagens desta situação tornam difícil uma homogeneização de critérios e atitudes. Objetivo: Orientar a abordagem e seguimento das crianças com má evolução ponderal. Métodos: Revisão de artigos pertinentes p...
Mesoporous carbon as an efficient catalyst for alcoholysis and aminolysis of ep...
Matos, I; Neves, P; Castanheiro, J; Perez-Mayoral, E; Martin-Aranda, R; Duran-Valle, C; Vital, J; Botelho do Rego, A; Fonseca, IThe ring opening reaction of epoxides by alcohols and amines using mesoporous activated carbon as efficient and environmentally friendly heterogeneous catalyst is reported. Carbon xerogels were synthesized by polymerization of resorcinol and formaldehyde. The surface of the activated carbon was oxidized in liquid phase with HNO3 and then functionalized with H2SO4. Chemical and textural characterization by eleme...
SBA-15 with sulfonic acid groups as a Green Catalyst for the acetoxylation of α...
Machado, J; Castanheiro, J; Matos, I; Ramos, A; Vital, J; Fonseca, IThe acetoxylation of a-pinene was carried out over SBA-15 with sulfonic acid groups. The products of acetoxylation of a-pinene are acetates (a-terpinyl acetate, bornyl acetate and b-fenchyl acetate) and hydrocarbons (camphene, tricyclene, limonene, g-terpinene, terpinolene and a-terpinene). Catalysts with different amount of sulfonic acid groups were prepared. It was observed that the activity increases with in...
Psychotic aura symptoms in familial hemiplegic migraine type 2 (ATP1A2)
Barros, J.; Mendes, A.; Matos, I.; Pereira-Monteiro, J.Abstract INTRODUCTION: Neuropsychological symptoms are rare in familial hemiplegic migraine (FHM). There are no reports of psychotic symptoms in FHM type 2 (ATP1A2). We examined a family with a FHM phenotype due to a M731T mutation in ATP1A2. A 10-year follow-up allowed us to observe complex auras, including psychotic symptoms in two siblings. CASE REPORT: Male, 48 years old, with an aura that included complex...
Methoxylation of alpha-pinene over heteropolyacids immobilized in silica
Pito, DS; Matos, I; Fonseca, I; Ramos, A; Vital, J; Castanheiro, JoséThe methoxylation of a-pinene was studied using heteropolyacids immobilized on silica as catalysts, at 60 ºC, being the a-terpinyl methyl ether the main product. Tungstophosphoric acid (PW), molybdophosphoric acid (PMo), tungstosilicic acid (SiW) and molybdosilicic acid (SiMo) were immobilized on silica by sol–gel method. It was observed that the catalytic activity of the silica-supported heteropolyacids decrea...
Kalirin: a novel genetic risk factor for ischemic stroke
Krug, T; Manso, H; Gouveia, L; Sobral, J; Xavier, J; Albergaria, I; Gaspar, G; Correia, M; Viana-Baptista, M; Simões, R; Pinto, A; Taipa, R; Ferreira, CCerebrovascular and cardiovascular diseases are the leading causes of death and disability worldwide. They are complex disorders resulting from the interplay of genetic and environmental factors, and may share several susceptibility genes. Several recent studies have implicated variants of the Kalirin (KALRN) gene with susceptibility to cardiovascular and metabolic phenotypes, but no studies have yet been perfo...
Mitochondrial haplogroup H1 is protective for ischemic stroke in Portuguese pat...
Rosa, A; Fonseca, BV; Krug, T; Manso, H; Gouveia, L; Albergaria, I; Gaspar, G; Correia, M; Viana-Baptista, M; Simões, RM; Pinto, AN; Taipa, RBACKGROUND: The genetic contribution to stroke is well established but it has proven difficult to identify the genes and the disease-associated alleles mediating this effect, possibly because only nuclear genes have been intensely investigated so far. Mitochondrial DNA (mtDNA) has been implicated in several disorders having stroke as one of its clinical manifestations. The aim of this case-control study was to ...
