Are social representations of positive ageing really effective? the ageing pro...
Soares, Célia; Marques, António Manuel; Silva, Madalena Gomes da; Cerqueira, Andreia; Bonança, Íris; Arguello, PatriciaIn this paper we focused on the experiences of ageing from the perspective of elderly people. Our main aims were to explore their perceptions and representations about the ageing experience and to analyse if their conceptions are closer to positive social representations of active ageing or to ageist social assumptions. Thirty-five females (mean age of 80 years) and seven males (mean age of 73 years) participat...
End of Life in Neonatology: Palliative Care Integration
Soares, Célia; Serviço de Neonatologia. Departamento de Pediatria. Centro Hospitalar de São João/Faculdade de Medicina do Porto. Porto. Portugal.Background: Today the limitation of therapeutic effort and the neonatal palliative care are extremely important and had been increasingly done by several countries. Nevertheless, in Portugal, studies and guidelines regarding end of life attitudes are still a shortage.Material and Methods: We analyzed 49 files in a retrospective review of neonatal deaths between 2010 and 2012; the results were compared with thos...
Fungos produtores de micotoxinas
Soares, Célia; Abrunhosa, Luís; Venâncio, ArmandoAs micotoxinas são metabolitos tóxicos secundários produzidos por alguns fungos filamentosos que surgem de forma natural em produtos agroalimentares em todo o Mundo. As mais relevantes para a segurança sanitária de alimentos são as aflatoxinas, a ocratoxina A, a patulina, as fumonisinas, a zearalenona e o desoxinivalenol, estando a sua presença em alimentos regulamentada. Estas micotoxinas são produzidas princi...
Characterization of the mycoflora and the occurrence of mycotoxins in Portugues...
Soares, CéliaTese de doutoramento programa doutoral em Engenharia Química e Biológica ; The reduction of yield, quality, and nutritional value of grain cereals by filamentous fungi and subsequent contamination with mycotoxins is of great concern around the world. Mycotoxins are known to cause serious health problems in animals and some mycotoxins such as aflatoxins, fumonisins and ochratoxins, in particular, have also been...
Micotoxinas detectadas en productos alimenticios en Portugal : revisión
Abrunhosa, Luís; Morales-Valle, H.; Soares, Célia; Calado, Thalita; Vila-Chã, Ana; Pereira, M.; Venâncio, ArmandoLas micotoxinas son metabolitos tóxicos producidos por hongos filamentosos que aparecen de forma natural en productos agroalimentarios en todo el mundo. Las aflatoxinas, ocratoxina A, patulina, fumonisinas, zearalenona, tricotecenos y alcaloides del ergot son actualmente las más relevantes. Estas micotoxinas pueden ser producidas por especies que pertenecen a los géneros Aspergillus spp...
Taxonomy of Aspergillus: integration of methods for new and revisited species i...
Rodrigues, Paula; Soares, Célia; Santos, Cledir; Venâncio, Armando; Lima, NelsonAspergillus is a large genus and, as with fungi in general, its taxonomy is complex and ever evolving. Section Flavi is one of the most significant sections of the genus, for it comprises two distinct groups of species with great interest to food industry: one group includes the aflatoxigenic species, which cause serious problems in agricultural commodities, and the other includes the non-aflatoxigenic species ...
Three new aflatoxigenic species of Aspergillus section Flavi isolated in Portugal
Soares, Célia; Peterson, Stephen; Rodrigues, Paula; Lima, Nelson; Venâncio, ArmandoThree new aflatoxin-producing species isolated from two Portuguese commodities, almonds and maize, are described. A polyphasic approach based on phenotypic (morphology and extrolites) and molecular characterizations was used to identify these isolates as belonging to new species. From the study of the twenty two isolates obtained in maize and almonds, two were identified as Aspergillus flavus, six as A. minisc...
Contributions of Micoteca da Universidade do Minho to food mycology
Rodrigues, Paula; Soares, Célia; Freitas-Silva, Otniel; Santos, Cledir; Paterson, Russell; Kozakiewicz, Zofia; Venâncio, Armando; Lima, NelsonMicoteca da Universidade do Minho (MUM) is a collection of fungi established in 1996. Research involving secondary metabolites in the form of mycotoxins is paramount. An objective is to provide authentic strains for research in biotechnology, life sciences and challenge testing. Knowledge, information and training in mycology are promulgated by the biological resource centre. MUM is involved in projects which a...
Liquid chromatography for multimycotoxin detection for filamentous fungi identi...
Soares, Célia; Rodrigues, Paula; Freitas-Silva, Otniel; Abrunhosa, Luís; Venâncio, ArmandoMycotoxins are secondary metabolites produced by specific filamentous fungi. Among the most relevant mycotoxigenic producer fungi are some Aspergillus species such as the ones belonging to the Aspergillus section Flavi. These are known to produce the highly carcinogenic aflatoxins (AFB1, AFB2; AFG1 and AFG2) and cyclopiazonic acid (CPA) in agricultural commodities. Besides the issues related to food safety, afl...
Rapid HPLC method for simultaneous detection of aflatoxins and cyclopiazonic fr...
Soares, Célia; Rodrigues, Paula; Freitas-Silva, Otniel; Abrunhosa, Luís; Venâncio, ArmandoMycotoxins are secondary metabolites produced by moulds and are an important world-wide food safety concern. Among the most relevant mycotoxigenic producer fungi are some Aspergillus species in particular those belonging to the Aspergillus section Flavi. These are known to produce the highly carcinogenic aflatoxins in agricultural commodities. Due to its impact in animal and human health, these species are amon...
