Distribution of aflatoxin M1 during production of sheep and goat cheeses
Vaz, Andreia; Mendonça, Álvaro; Rodrigues, Paula; Venâncio, ArmandoThe occurrence of Aflatoxin M1 (AFM1) in milk results from ingestion of contaminated feed with Aflatoxin B1 by dairy animals, its conversion into AFM1, and secretion in milk. The objective of this work was to investigate AFM1 fate along goat and sheep cheese production. Cheese production was carried out using spiked milk (levels between 0.08 and 0.10 μg/L). Samples were collected throughout the production and a...
Frontiers in neurogenesis
Vaz, Andreia; Ribeiro, Inês; Pinto, LuísaOne of the most intriguing dogmas in neurosciences—the empirical lack of brain neuronal regeneration in adulthood onwards to late life—began to be debunked initially by research groups focused on understanding postnatal (early days/weeks of murine and guinea pigs) neurodevelopmental and neuroplastic events [...]

Relational and Communicational Skills of Nursing Students
Torres, Ana; Reis, Juliana; Franco, Alexandra; Rodrigues, Ana; Vaz, Andreia; Amaral, Cátia; Pinto, Mariana; Catela, Patricia; Soares, SérgioIntroduction: Communicational and relational skills are crucial for nursing care and are recognized as a differentiating competence of excellent care. Nursing students must develop these skills to establish an efficient helping relationship. Despite of that, studies about the efficiency of interventions to promote these skills are scarce. This study aims to evaluate the acquisition of communicational and relati...
Aflatoxin M1 in Europe between 1990-2018
Vaz, Andreia; Mourão, Filipa; Costa, Patrícia; Rodrigues, Paula; Venâncio, ArmandoAflatoxin M1 (AFM1) is a carcinogen metabolite that can be present in milk from lactating animals that consume aflatoxin B1 (AFB1) contaminated feed. AFM1, in addition to being hepatotoxic and causing carcinogenic effects, is relatively stable during milk pasteurization, storage and processing of various dairy products, which makes it a potential food contaminant. Consumption of dairy products has expanded rapi...
Detection methods for aflatoxin M1 in dairy products
Vaz, Andreia; Silva, Ana C. Cabral; Rodrigues, Paula; Venâncio, ArmandoMycotoxins are toxic compounds produced mainly by fungi of the genera Aspergillus, Fusarium and Penicillium. In the food chain, the original mycotoxin may be transformed in other toxic compounds, reaching the consumer. A good example is the occurrence of aflatoxin M1 (AFM1) in dairy products, which is due to the presence of aflatoxin B1 (AFB1) in the animal feed. Thus, milkbased foods, such as cheese and yogurt...

Optimization and validation of two methods to determine the levels of AFM1 in m...
Vaz, Andreia; Gomes, Francileni Pompeu; Alves, A.; Rodrigues, Paula; Venâncio, ArmandoConsumption of dairy products has expanded rapidly over the past decade and constitutes an important source of dietary protein. 1 Aflatoxin M1 (AFM1) is a potent carcinogen metabolite that can be present in milk from dairy cows that consume feed contaminated with Aflatoxin B1. Even though it is less toxic than its parent compound, AFM1 is hepatotoxic and carcinogenic, and is stable during milk pasteurization, s...
Thin films sensor devices for mycotoxins detection in foods: applications and c...
Santos, Andreia O.; Vaz, Andreia; Rodrigues, Paula; Veloso, Ana C.A.; Venâncio, Armando; Peres, António M.Mycotoxins are a group of secondarymetabolites produced by different species of filamentous fungi and pose serious threats to food safety due to their serious human and animal health impacts such as carcinogenic, teratogenic and hepatotoxic effects. Conventional methods for the detection of mycotoxins include gas chromatography and high-performance liquid chromatography coupled with mass spectrometry or other d...
