Antifungal, molecular docking and cytotoxic effect of the essential oil of Cymb...
Prado, Guilherme; De Aguiar, Francisca; Barbosa, Francisco; Do Vale, Jean; Martins, M. Rosário; Macedo-Arantes, Silvia; De Sousa, NatáliaBrazil is renowned for its extensive plant biodiversity, with emphasis on Cymbopogon, C. citratus and C. nardus, with broad antimicrobial potential. Candidemias caused by Candida albicans are highly prevalent in immunosuppressed individuals and are associated with infections by biofilms on medical devices. The aim of this study was to evaluate the antimicrobial potential of essential oils C. citratus and C. nar...
Rosmaninhos do sul de Portugal: perfil químico e propriedades biológicas das su...
Macedo-Arantes, Silvia; Caldeira, A. Teresa; Pereira, Marízia; Martins, M. RosárioAs lavandas e rosmaninhos, pertencentes ao género Lavandula apresentam grande importância económica, não só na indústria cosmética e perfumaria como também na indústria alimentar e farmacêutica, pelas suas importantes propriedades biológicas e farmacológicas dos seus óleos essenciais, apesar das diferenças observadas no perfil químico dos seus óleos essenciais. Estão descritas mais de trinta espécies de Lavandu...
Microbial communities of underwater caves from Algarve coast: Biological activi...
Salvador, Cátia; Arantes, Silvia; Martins, M. Rosário; Candeias, António; Saiz-Jimenez, Cesáreo; Caldeira, A. TeresaMicroorganisms are known to be an important source of bioactive compounds. Lately, the microbiota of hypogenic environments, such as underwater caves, has been explored, since they constitute complex ecosystems, which bring unique conditions for the development of organism’s niches with unknown biodiversity. These microorganisms may have interesting characteristics regarding the high potential to produce new bi...
Prospection of bioactive compounds produced by bacterial isolates from pristine...
Gatinho, Patrícia; Salvador, Cátia; Arantes, Sílvia; Martins, M. Rosário; Silva, Amélia; Miller, Ana; Caldeira, A. TeresaPristine environments can be defined as places with limited or no connections to anthropogenic activities [1], for example, karstic and marine caves, important landmarks of Natural and Cultural Heritage. Usually, these environments are exposed to extreme factors such as temperature, salinity, osmolarity, UV radiation, pressure, or pH, with values close to the limit of life. In these extreme environments, living...
Evaluating Students’ Literacy on Safe Pesticide Use and Sustainable Resource Ma...
Coelho, Cristina; Martins, M. Rosário; Vicente, HenriqueThe intensive use of pesticides contaminates soil and water, raising the risk of diseases like cancer and hormonal/neurological disorders. The continuous exposure to pesticides through water and food is concerning. Therefore, raising awareness about biological pest control is essential to reduce the harmful impact of pesticides on food and the environment. This study evaluates students’ literacy on pesticide us...
Essential Oils High in 1,8-Cineole of Mediterranean Flavoring Plants: Health Be...
Macedo Arantes, Sílvia; Caldeira, A. Teresa; Martins, M. RosárioAromatic flavouring plants are important ingredients of the Mediterranean Diet, one of the healthiest and most sustainable dietary forms, often associated with greater longevity as well as contributing to the reduction of some chronic pathologies with high mortality and morbidity. Their essential oils are increasingly used as therapeutic agents and food supplements, due to their antioxidants, anti-inflammatory ...
An Entropic Approach to Assess People’s Awareness of the Health Risks posed by ...
Crespo, Ana; Lima, Rui; Martins, M. Rosário; Ribeiro, Jorge; Neves, José; Vicente, HenriqueWine production and vineyard work are seasonal activities as there is a period when no intervention is required and oenotourism may fill that void. On the other hand, given that grapevines are tied to this area of activity, it is of paramount importance to assess customer and staff awareness of the health risks of pesticide use, that emerge from people's responses to specific questionnaires. Therefore, a workab...
Gongronella eborensis sp. nov., from vineyard soil of Alentejo (Portugal)
Martins, M. Rosário; Santos, Carla; Soares, Célia; Santos, Cledir; Lima, NelsonThis study describes a novel fungal species belonging to the genus Gongronella. During a previous work focusing on metalaxyl degradation by Mucorales strains, two isolates from vineyard soil samples collected in the Alentejo region, south Portugal, were identified as a putative novel species based on combined molecular and MALDI-TOF MS data. This new species is described here using a polyphasic approach that co...
Essential oils of Portuguese flavouring plants: potential as green biocides in ...
Macedo-Arantes, Sílvia; Piçarra, Andreia; Caldeira, A. Teresa; Candeias, António E.; Martins, M. RosárioMicrobial biodeterioration is a growing problem in cultural heritage (CH). Many biocides used to control CH biodeterioration have toxic effects and risks of contamination for health and the environment. Essential oils (EOs) due to their antimicrobial potential and low toxicity represent a sustainable and safe alternative in the control of microbial growth in heritage assets. Nevertheless, EOs volatility is one ...
Antimicrobial and antitumoral potential use of essential oils from Calamintha n...
Arantes, Sílvia; Piçarra, Andreia; Salvador, Cátia; Candeias, M. Fátima; Caldeira, A. Teresa; Martins, M. RosárioAromatic plants are appreciated as food flavors, being preserved and consumed by the local population in daily diets, and in Mediterranean Diet. Essential oils (EOs), complex mixtures rich in terpene compounds, have shown several biological properties, mainly as antimicrobials and antioxidants. Alentejo, S.W. of Portugal, is very rich in flavoring autochthones aromatic plants. Therefore, it is important to eval...
