Cell Wall-Mediated Antifungal Activity of the Aqueous Extract of Hedera helix L...
Crisóstomo, Christina; Simões, Luara; Barros, Lillian; Finimundy, Tiane C.; Cunha, Ana; Oliveira, Rui P.Cork oak forests have been declining due to fungal pathogens such as Diplodia corticola. However, the preventive fungicides against this fungus have restricted use due to the deleterious effects on human health and the environment, prompting the need for sustainable alternatives. Here, we describe the antifungal activity of an aqueous extract of Hedera helix L. leaves (HAE) against D. corticola and the possible...
Antifungal and antioomycete activities of a curcuma longa L. hydroethanolic ext...
Cruz, Adriana; Sánchez-Hernández, Eva; Teixeira, Ana; Martín-Ramos, Pablo; Cunha, Ana; Oliveira, RuiCurcuma longa, known for its anti-inflammatory, antioxidant, and antimicrobial properties, has been a staple in traditional medicine for centuries. In the pursuit of natural alternatives to synthetic preservatives, the extracts of C. longa have garnered attention for their efficacy in extending shelf life and preventing the spoilage of diverse agricultural products. This study aims to assess the antifungal and ...
Phytoconstituents and ergosterol biosynthesis-targeting antimicrobial activity ...
Cruz, Adriana; Sánchez-Hernández, Eva; Teixeira, Ana; Oliveira, Rui; Cunha, Ana; Martín-Ramos, PabloIn recent years, nutmeg (Myristica fragans Houtt.) has attracted considerable attention in the field of phytochemistry due to its diverse array of bioactive compounds. However, the potential application of nutmeg as a biorational for crop protection has been insufficiently explored. This study investigated the constituents of a nutmeg hydroethanolic extract via gas chromatography-mass spectrometry and vibration...
Are tomato plants co-exposed to heat and salinity able to ensure a proper carbo...
Rodrigues, Francisca; Sousa, Bruno; Soares, Cristiano; Moreira, Diana; Pereira, Cláudia; Moutinho-Pereira, José; Cunha, Ana; Fidalgo, FernandaAbiotic stress combinations, such as high temperatures and soil/water salinization, severely threaten crop productivity worldwide. In this work, an integrative insight into the photosynthetic metabolism of tomato plants subjected to salt (100 mM NaCl) and/or heat (42 °C; 4 h/day) was performed. After three weeks, the stress combination led to more severe consequences on growth and photosynthetic pigments than t...
The positive and negative suicidal ideation inventory among portuguese adolesce...
Brás, Marta; Cunha, Ana; Antunes, João; Carmo, CláudiaSuicide worldwide is an issue that needs to be addressed, and adolescents are an at-risk group. Assessing suicidal ideation is central to tackling the issue of suicide. The Positive and Negative Suicidal Ideation inventory is a widely validated measure of suicidal ideation, and yet, very little is known about its invariance across various groups. The present study aimed to adapt and test the PANSI’s structure i...

Accounting Standardization in the Municipality of Elvas: stages and challenges
Ventura, Ricardo; Silva, Amélia; Cunha, Ana; Oliveira, Helena CostaThe biggest change of paradigm in the accounting system of the Portuguese public sector, take place in 1997 with the public sector reform, which materialized through the Public Official Accounting Plan. However, despite the important role played by this accounting standard, it could not keep up with international standards or the evolution of accounting in the private sector. These facts along with the multipli...
Developing a Compost Quality Index (CQI) based on the electrochemical quantific...
Silva, Ana Catarina; Rocha, Pedro; Geraldo, Dulce; Cunha, Ana; Antelo, Juan; Pinheiro, José P.; Fiol, Sarah; Bento, M. FátimaThe present work demonstrates the use of Cd<sup>2+</sup> as a reactivity probe of the fulvic acids (FAs), humic acids (HAs) and dissolved organic matter (DOM) compost extracts. Significant differences were observed between the extracts, with the HA extract showing the highest reactivity. Comparing the different composts, the largest reactivity variation was again observed for HA then FA and finally DOM extracts...
The influence of light microclimate on the lipid profile and associated transcr...
Garrido, Andreia; Conde, Artur Jorge Silva; De Vos, Ric C.H.; Cunha, AnaLipids and oils determine the quality and industrial value of grape seeds. Studies with legume seeds demonstrated the influence of light on lipid metabolism and its association with seed photosynthesis. Grape berry seeds are photosynthetically active till mature stage, but mostly during the green stage and veraison. The objective of this work was to compare the lipid profiles of seeds from white grape berries (...
Antifungal activity of plant waste extracts against phytopathogenic fungi: Alli...
Teixeira, Ana; Sánchez-Hernández, Eva; Noversa, João; Cunha, Ana; Cortez, Isabel; Marques, Guilhermina; Martín-Ramos, PabloThe harmful effect of synthetic fungicides on the environment and the development of resistance by fungi raises concerns about their security and future efficacy. In this work, we investi gated plant by-products with the antifungal activity that could be safe alternatives to conventional fungicides. The in vitro antifungal potential of plant by-product extracts showed that garlic peel extract (GPE) was the most...
