Greater Impact of Living Donation Than HLA Mismatching in Short-Term Renal Allo...
Ribeiro, Bárbara; Reis Pereira, Pedro; Oliveira, João; Almeida, Manuela; Martins, La Salete; J, MalheiroIntroduction: Living donor kidney transplantation (LDKT) is accepted as first-line treatment for patients with end-stage kidney disease with advantages over deceased donor kidney transplantation (DDKT). Still, how the known detrimental effect of HLA mismatch (MM) may hamper these advantages remains unsettled. We sought to determine the effect of the degree of HLA MM, separately in deceased and living donor rena...
Reducing the carbon footprint through textile reuse: the case study of a textil...
Ribeiro, Bárbara; Amorim, Ana Paula; Marinho Reis, A. PaulaAfter food, housing, and transport, textiles are the fourth most pressured category in terms of raw material and water use, and the fifth in terms of greenhouse gas emissions. In order to significantly reduce waste and the use of natural resources in the textile and clothing industry, and to reduce the environmental impact associated with the sector, thus contributing to sustainable development, there is a need...
Female sexual dysfunction in the reproductive years: Prevalence and associated ...
Ribeiro, Bárbara; Magalhães, Ana Teresa; Mota, IvoneObjectives: Sexual dysfunction is believed to exist in 40% to 70% of the population in Portugal. It is defined by pain or alteration of function in the phases of the sexual act. The present study was designed to estimate the prevalence of sexual dysfunction in women of reproductive age, the prevalence of the various subtypes of sexual dysfunction, and the factors associated with female sexual dysfunction. Study...
Do bioactive carotenoids contribute to the color of edible mushrooms?
Ribeiro, Bárbara; Pinho, Paula Guedes de; Andrade, Paula B.; Oliveira, Carla; Ferreira, António César Silva; Baptista, Paula; Valentão, PatríciaCarotenoids are biologically active phytochemicals present as micro-components in fruits and vegetables, being responsible for their yellow, orange and red colors. The chromatographic behavior and the UV absorption spectrum provided by HPLC-DAD analysis constitute the clues for their identification. Mushrooms are of increasing importance in modern nutrition and medicine, due to the presence of metabolites with ...
Metabolite profiling of wild edible mushrooms species
Valentão, Patrícia; Ribeiro, Bárbara; Pinho, P. Guedes de; Baptista, Paula; Andrade, Paula B.Mushrooms are of increasing importance in modern nutrition and medicine. Trás-os-Montes region (north-eastern Portugal) is known for the variety of its soils and diversity of climate conditions. This variability assumes an important role in mushroom production, explaining why this region is recognized as one of the richest ones in wild edible species. A metabolomics approach was applied to twelve wild edible mu...
Fatty acid composition of wild edible mushrooms species: a comparative study
Ribeiro, Bárbara; Pinho, P. Guedes de; Andrade, Paula B.; Baptista, Paula; Valentão, PatríciaA comparative study was developed on the total fatty acids composition of twelve wild edible mushroom species (Suillus bellini, Suillus luteus, Suillus granulatus, Hygrophorus agathosmus, Amanita rubescens, Russula cyanoxantha, Boletus edulis, Tricholoma equestre, Fistulina hepatica, Cantharellus cibarius, Amanita caesarea and Hydnum rufescens). In order to define qualitative and quantitative profiles, combined...
Aroma compounds in eleven edible mushroom species: relationship between volatil...
Pinho, P. Guedes de; Ribeiro, Bárbara; Gonçalves, Rui; Baptista, Paula; Valentão, Patrícia; Seabra, Rosa M.; Andrade, Paula B.Volatile and semi-volatile components of 11 wild edible mushrooms, Suillus bellini, Suillus luteus, Suillus granulatus, Tricholomopsis rutilans, Hygrophorus agathosmus, Amanita rubescens, Russula cyanoxantha, Boletus edulis, Tricholoma equestre, Fistulina hepatica and Cantharellus cibarius, were determined by headspace solidphase microextraction and by liquid extraction combined with gas chromatographymass spec...
Comparative study of phytochemicals and antioxidant potential of wild edible mu...
Ribeiro, Bárbara; Lopes, Rosário; Andrade, Paula B.; Seabra, Rosa M.; Gonçalves, Rui; Baptista, Paula; Quelhas, Inês; Valentão, PatríciaA comparative study of the organic acids and phenolics composition and of the total alkaloids content of entire wild edible mushrooms (Russula cyanoxantha, Amanita rubescens, Suillus granulatus and Boletus edulis) and correspondent caps and stipes was performed. All species presented oxalic, citric, malic and fumaric acids, with A. rubescens exhibiting the highest total organic acids content. Organic acids were...

Pereira, David M.; Ribeiro, Bárbara; Andrade, Paula B.; Baptista, Paula; Barros, Lillian; Ferreira, Isabel C.F.R.; Seabra, Rosa M.; Valentão, Patrícialn order to study the influence 01 lour inorganic nitrogen sources (NH4N03, NaN02, KN03 and (NH4)2HP04) on the chemical composition 01 Leucopaxillus giganteus mushroom mycelium, its organic acids profile was determined by HPLC-UV and total alkaloids content was assessed by a spectrophotometric method, alter precipitation by Dragendorlf's reagent. lhe results showed that L. giganteus presented an organic acids p...
Leucopaxillus giganteus mycelium: effect of nitrogen source on organic acids an...
Ribeiro, Bárbara; Andrade, Paula B.; Baptista, Paula; Barros, Lillian; Ferreira, Isabel C.F.R.; Seabra, Rosa M.; Valentão, PatríciaThe aim of this work was to find the most useful inorganic nitrogen source to enable Leucopaxillus giganteus to become a more nutritious mushroom, regarding organic acid and phenolic composition and total alkaloids content. For these, the influence of NH4NO3,NaNO2, KNO3,, and (NH4)2HPO4 on the organic acid production was determined by HPLC-UV and total alkaloid content was assessed by a spectrophotometric metho...
