Pollen- and Weather-Based Machine Learning Models for Estimating Regional Olive...
Galveias, Ana \; Fraga, Helder; Costa, Ana Rodrigues; Antunes, Célia M.The olive tree is one of the most common type of cultivation in the Mediterranean area, having high economic and social importance. The Alentejo region, Portugal, is an area with a high presence of olive groves, which in 2022 accounted for 201,474 hectares. The aim of this study was to assess the relationship between olive pollen, weather data, and olive tree production, between the years 2002 and 2022. Pollen ...
Antimicrobial, Antibiofilm and Toxicological Assessment of Propolis
Queiroga, Maria Cristina; Laranjo, Marta; Andrade, Nara; Marques, Mariana; Costa, Ana Rodrigues; Antunes, Célia MariaAntimicrobial resistance is a serious problem for the control of infections and infectious diseases. Propolis is a substance produced by honeybees with antimicrobial and antibiofilm properties. To consider propolis as an alternative to the use of antimicrobials for infection control, we assessed its antimicrobial and antibiofilm activities. To assess propolis for topical medical use, toxicological studies were ...
Comparison of salivary proteome of children with different sensitivities for bi...
Rodrigues, Lénia; Espanca, Rosa; Costa, Ana Rodrigues; Antunes, Célia Miguel; Pomar, Clarinda; Capela e Silva, Fernando; Pinheiro, Cristina ConceiçãoBackground/objectives Oral sensorial perception is a key aspect in food choices and knowing the mechanisms modulating such perception is of major importance in the context of child obesity, which is reaching high rates in Mediterranean countries. Salivary proteome has been linked to taste sensitivity in adults. The aim of this study was to search for differences in salivary proteomes of children with different ...
Novel hydroxyamides and amides containing D-glucopyranose or D-fructose units: ...
Carreiro, Elisabete P.; Costa, Ana Rodrigues; Cordeiro, Maria M.; Martins, Rute; Pires, Tiago O.; Saraiva, Mafalda; Antunes, Célia M.; Burke, Anthony J.A novel library of 15 compounds, hydroxyamides and amides containing a β-d-glucopyranose (d-Gluc) or a β-d-fructose (d-Fruc) units was designed and synthesized for antiproliferative assays in breast (MCF-7) and colon (MDST8) cancer cell lines. Twelve of them were hydroxyamides and were successfully synthesized from β-d-glucuronic acid (d-GluA). Six of these hydroxyamides which were acetylated hydroxy-β-d-glucop...
Changes in the salivary protein profile of morbidly obese women either previous...
Lamy, Elsa; Simões, Carla; Rodrigues, Lénia; Costa, Ana Rodrigues; Vitorino, Rui; Amado, Francisco; Antunes, Célia; Carmo, Isabel doSaliva is a non-invasive source of biomarkers useful in the study of physiological mechanisms. Moreover, this fluid has diverse functions, among which food perception and ingestion, making it particularly suitable for the study of obesity. The aims of this study were to assess changes in salivary proteome among morbidly obese women, with a view to provide information about mechanisms potentially related to the ...
Alterações na actividade enzimática da amílase salivar em indivíduos obesos
Simões, Carla; Costa, Ana Rodrigues; Antunes, Célia M; Lamy, ElsaNos últimos anos o estudo da composição proteica da saliva ganhou interesse pelo seu potencial no diagnóstico não invasivo e compreensão de diversas doenças, quer orais, quer sistémicas. Para além disso, a interacção deste fluido com os constituintes dos alimentos tornam a sua análise importante para a compreensão das variações a nível da percepção dos alimentos e escolhas alimentares. Há, contudo, poucos estud...
The Effect of Tannins on Mediterranean Ruminant Ingestive Behavior: The Role of...
Lamy, Elsa; Rawel, Harshadrai; Schweigert, Florian J.; Capela e Silva, Fernando; Ferreira, Ana; Costa, Ana Rodrigues; Antunes, CéliaAbstract: Sheep, cattle and goat are domestic ruminants of significant economic interest in the Mediterranean region. Although sharing the same pasture ranges, they ingest different plants and plant parts and, consequently different levels of tannins. This suggests an ability to detect and adapt ingestion according to animal physiological limits of tolerance for plant secondary metabolites. This review will det...

Abnormal regulation of Na,K-ATPase in Glucose Intolerant Rats.
Costa, Ana Rodrigues; Antunes, Célia M.; Cruz-Morais, JulioIntroduction: Glucose is the most important physiological insulin secretagogue. However, the mechanisms underlying glucose-induced insulin release are not fully understood. The role of electrogenic systems such as ionic pumps, to these events remains essentially uninvestigated. Na,K-ATPase, responsible for maintaining Na+ and K+ gradients across the plasma membrane and generates a net outward current, thus chan...
