Assessment of physicochemical parameters in two winegrapes varieties after foli...
Daccak, Diana; Lidon, Fernando C.; Coelho, Ana Rita F.; Luís, Inês Carmo; Marques, Ana Coelho; Pessoa, Cláudia Campos; Brito, Maria da GraçaOne-third of the world’s population is suffering from “hidden hunger” due to micronutrient deficiency. Zinc is acquired through diet, leading its deficiency to the development of disorders such as retarded growth, anorexia, infections, and hypogeusia. Accordingly, this study aimed to develop an agronomic workflow for Zn biofortification on two red winegrapes varieties (cv. Castelão and Syrah) and determine the ...
Gender bias in career choice in Brazil
Pessoa, Maria Fernanda; Vaz, Daniela Verzola; Botassio, Diego CamargoThis article analyzes sex segregation in in-person higher education programs in Brazil by investigating its causes, characteristics and evolution over time. To that end, synthetic indicators of segregation are calculated based on the 2000 and 2017 editions of the Censo da Educação Superior [Higher Education Census]. During this period, the decrease in the overall degree of segregation was subtle, as a result of...
Chemical composition and omega 3 human health benefits of two sea cucumber spec...
Sales, Sabrina; Lourenço, Maria Helena; Pessoa, Maria Fernanda; Pombo, Ana; Félix, Pedro Miguel; Bandarra, Narcisa MariaThe main goal of this study was to investigate the seasonal chemical changes of two sea cucumber species caught from Portugal. The potential contribution to human health of lipids was also evaluated. For this, the chemical composition (protein, ash, and fat) and lipids composition of Holothuria arguinensis and Holothuria forskali was followed in summer and winter. Both species presented adequate levels of prote...
Calcium biofortification of Rocha pears, tissues accumulation and physicochemic...
Pessoa, Cláudia Campos; Lidon, Fernando C.; Coelho, Ana Rita; Caleiro, João; Marques, Ana Coelho; Luís, Inês Carmo; Kullberg, José CarlosLow dietary intake of Ca in humans has been epidemiologically linked to various diseases, which can have serious health consequences over time. Accordingly, the development of an agronomic itinerary for Ca biofortification of Rocha pears and the assessment of physicochemical deviations prompted this study. Two orchards with contrasting soil and water characteristics were selected, characterized through orthopho...
Zinc Enrichment in Two Contrasting Genotypes of Triticum aestivum L. Grains: In...
Luís, Inês Carmo; Lidon, Fernando C.; Pessoa, Cláudia Campos; Marques, Ana Coelho; Coelho, Ana Rita F.; Simões, Manuela; Patanita, Manuel; Dôres, JoséThis study aimed to assess the implications of Zn enrichment in wheat grains as a function of contrasting genotypes, edaphic conditions and foliar fertilizers. Triticum aestivum L. varieties Roxo and Paiva were grown in four production fields, and sprayed with ZnSO4 (0, 16.20 and 36.40 kg/ha) Zn-EDTA (0, 6.30 and 12.60 kg/ha) and Tecnifol Zinc (0, 3.90 and 7.80 kg/ha). The heterogeneous edaphic conditions of th...
Corema album spp: Edible wild crowberries with a high content in minerals and o...
Brito, Catarina; Bertotti, Taciana; Primitivo, Maria João; Neves, Marta; Pires, Cristiana L.; Cruz, Pedro F.; Martins, Patrícia A. T.Edible wild plants are part of the ethnobotanical and gastronomic heritage of different geographical areas. Corema album (L.) D. Don is an endemic species of the dune systems of the Atlantic coast of the Iberian Peninsula. The aerial parts of Corema album are a source of nutrients and antioxidants. The Corema album white berry (Portuguese crowberry) is rich in calcium, iron, and zinc. The plant also shows high ...
Quantification and tissue localization of selenium in rice (Oryza sativa L., Po...
Marques, Ana Coelho; Lidon, Fernando C.; Coelho, Ana Rita F.; Pessoa, Cláudia Campos; Luís, Inês Carmo; Scotti-Campos, Paula; Simões, ManuelaIn worldwide production, rice is the second-most-grown crop. It is considered a staple food for many populations and, if naturally enriched in Se, has a huge potential to reduce nutrient deficiencies in foodstuffs for human consumption. This study aimed to develop an agronomic itinerary for Se biofortification of Oryza sativa L. (Poaceae) and assess potential physicochemical deviations. Trials were implemented ...
Resposta do trigo a sementes tratadas com zinco e aplicação de zinco ao solo
Arrobas, Margarida; Afonso, Sandra; Coutinho, José Norberto P.; Lidon, Fernando; Almeida, Ana Sofia; Reboredo, Fernando; Pessoa, Maria FernandaDe acordo com a Organização Mundial de Saúde diarreia e pneumonia são duas importantes causas de mortalidade infantil que podem estar associadas a deficiência em zinco (Zn). O Zn é um elemento essencial para as plantas, onde exerce papel estrutural e é co-factor de mais de 300 enzimas. Na perspetiva da biofortificação, interessa saber se é possível aumentar a concentração em Zn nas partes comestíveis das planta...
Resposta do trigo a sementes tratadas com zinco e aplicação de zinco ao solo
Arrobas, Margarida; Afonso, Sandra; Coutinho, José Norberto P.; Lindon, Fernando; Almeida, Ana Sofia; Reboredo, Fernando; Pessoa, Maria FernandaO trigo é um dos principais constituintes da dieta da humanidade. Nesta perspetiva, assume particular importância o enriquecimento do grão em nutrientes que possam colmatar carências nutricionais, como é o caso do zinco (Zn). De acordo com a Organização Mundial de Saúde diarreia e pneumonia são duas importantes causas de mortalidade infantil que podem estar associadas a deficiência em zinco. Cerca de 40% da pop...
