Impact of a combined physical exercise and sensory stimulation program on the q...
Marinho, M.; Coelho, E.; Afonso, C.; Pereira, Antonino; Mourão Carvalhal, M.; Fonseca, S.; Corresponding author: Fonseca, S..The search for effective non-pharmacological interventions for institutionalized older adults has intensified, particularly those capable of meaningfully enhancing their well-being and quality of life. However, scientific evidence regarding the combined use of physical exercise and sensory stimulation in this population remains limited, leaving an important gap in geriatric practice. This qualitative, explorato...
The effect of drying process on undervalued brown and red seaweed species: elem...
Afonso, C.; D. R., Julião; Pinto, Edgar; Almeida, A.; M. P. L. V. O. Ferreira, I.; M. Bandarra, N.; Cardoso, CarlosThe infuence of drying (sun-drying and shade-drying) on the elemental composition of two brown seaweeds (Treptacantha abies-marina, Cystoseira humilis) and two red seaweed species (Asparagopsis armata and Asparagopsis taxiformis) harvested in the Faial Island (Azores Islands, Portugal) was assessed. The contents of sixteen nutritionally and toxicologically relevant elements were determined: sodium (Na), magnesi...
Farming a wild seaweed and changes to its composition, bioactivity, and bioacce...
Cardoso, C.; Almeida, J.; Coelho, I.; Delgado, I.; Gomes, R.; Quintã, R.; Bandarra, N.M.; Afonso, C.The nutritional value, elemental and fatty acid composition as well as key biological activities were determined in a large brown seaweed species (Saccorhiza polyschides, abundant in European shores), taking into account the effects of wild vs farmed and land-based vs open sea Integrated Multi-Trophic Aquaculture (IMTA) system dichotomies. The results showed that S. polyschides has significant amounts of releva...
Elemental composition and in vitro bioaccessibility assessment of holothuroids
Sales, S.S.; Lourenço, H.M.; Bandarra, N.M.; Cardoso, C.; Brito, P.; Botelho, M.J.; Gonçalves, S.; Coelho, I.; Delgado, I.; Pessoa, M.F.; Félix, P.M.The elemental composition and bioaccessibility of the wild holothuroids Holothuria arguinensis, Holothuria forskali, and Holothuria mammata was studied. Nutritional and toxicological aspects were evaluated. H. mammata was the richest in Mn, Ni, As, Cd, Pb, and Hg; H. forskali had the highest Cu and I contents, 4.12–4.93 mg/kg dw and 28.02–28.26 mg/kg dw, respectively; and Summer H. arguinensis had high Se conte...
Seasonal variation of chub mackerel (Scomber colias) selenium and vitamin B12 c...
Rego, A.; Coelho, I.; Motta, C.; Cardoso, C.; Gomes-Bispo, A.; Afonso, C.; Prates, J.A.M.; Bandarra, N.M.; Silva, J.A.L.; Castanheira, I.Chub mackerel (Scomber colias), an underutilised fish species, has been identified as an excellent source of selenium and vitamin B12, which may prevent and delay cognitive decline and dementia. Given these nutrients’ contents seasonal variability, a complete monthly sampling, involving a specifically adjusted methodology for the determination of vitamin B12 (LC-MS/MS) and its main vitamers and a sensitive anal...
Seasonality as experienced in the market and the resulting variation in the ami...
Motta, C.; Rego, A.; Cardoso, C.; Coelho, I.; Gomes-Bispo, A.; Afonso, C.; Prates, J.A.M.; Castanheira, I.; Bandarra, N.Chub mackerel (Scomber colias) is an underutilised fish species, abundant in the Atlantic Ocean. Its amino acid profile and elemental composition are still insufficiently studied. Accordingly, these aspects were studied on a monthly basis. The most abundant essential amino acids, lysine and leucine, had contents ranging from 1270 ± 40 mg/100 g in August to 1820 ± 96 mg/100 g in November and from 1210 ± 36 mg/10...
Human health risk–benefit assessment of fish and other seafood: a scoping review
Thomsen, S.T.; Assunção, Ricardo; Afonso, C.; Boué, G.; Cardoso, C.; Cubadda, F.; Garre, A.; Kruisselbrink, J.; Mantovani, A.; Pitter, J.; Poulsen, M.Fish and other seafood are important sources of nutrients, but they are also sources of chemical contaminants that may cause adverse health effects. This article aimed to identify existing risk–benefit assessments (RBA) of fish, shellfish, and other seafood, compare methodologies, discuss differences and commonalities in findings, and identify limitations and ways forward for future studies. We conducted a scop...
Bioactive and nutritional potential of Alaria esculenta and Saccharina latissima
Afonso, C.; Matos, J.; Guarda, I.; Gomes-Bispo, A.; Gomes, R.; Cardoso, C.; Gueifão, S.; Delgado, I.; Coelho, Inês; Castanheira, Isabel; Bandarra, N.M.The brown seaweed species Alaria esculenta and Saccharina latissima are commercial edible resources in Norway. There are knowledge gaps regarding these species. Accordingly, they were characterized and their bioactivity and bioaccessibility evaluated. The fatty acid (FA) analysis revealed anω-3/ω-6 ratio of almost 2 in A. esculenta vs 1 in S. latissima. The FAs 18:4ω-3 (stearidonic acid) and 20:5ω-3 (eicosapent...
Mackerel seasonality effect on Se content
Rego, A.; Ventura, M.; Gueifão, S.; Coelho, I.; Cardoso, C.; Afonso, C.; Bandarra, N.; Castanheira, I.Selenium is an essential micronutrient that can become toxic when ingested in high concentrations The human being can obtain Se through the consumption of food, dietary supplements, water and exposure to ambient air The food source is the most abundant and the main contributor to the daily intake of Se in Fish is one of the best sources of Se, and the Portuguese Mackerel is one of the most important and abundan...
Drying process, storage conditions, and time alter the biochemical composition ...
Regal, A.L.; Delgado Alves, Vitor; Gomes, R.; Matos, J.; Bandarra, N.M.; Afonso, C.; Cardoso, C.The Azorean red seaweed Asparagopsis taxiformis may be used in human and animal diets. This seaweed is deemed to reduce the large production of methane—a major greenhouse gas—by ruminant digestion. Seaweed producers, however, have difficulties in ensuring a reliable and similar product throughout all year and in different years. Changes in biochemical composition and bioactivity are caused not only by natural v...
