Assessing exposure to environmental contaminants in portuguese mother-infant pa...
Namorado, Sónia; Pastorinho, M. Ramiro; Simões, Mariana; Coelho, Susana; Lamy, Elsa; Silva, Susana Pereira; Ogura, Joana; Nunes, BaltazarObjective: Today chemicals play a major role in our daily lives, being present in the air we breathe, in the food we eat and in the products we use. As such, it is essential to know the levels of chemicals present in our bodies and assess the risks associated. For that, Human Biomonitoring (HBM), the measurement of the concentrations of chemicals in human biological samples, is a very useful technique. Neverthe...
Avaliação da toxicidade aguda associada a desinfetantes de uso comum no organis...
Barreto, Márcio; Coelho, Susana; Pastorinho, Manuel Ramiro; Sousa, Ana CatarinaA crise pandémica causada pela COVID-19 levou ao uso generalizado de produtos desinfetantes, incluindo desinfetantes de mãos de base hidroalcoólica. Face ao uso massivo é expectável que estes produtos acabem por ser introduzidos no meio ambiente, particularmente no ambiente aquático. Nesse sentido, é importante avaliar a potencial toxicidade que estes produtos apresentam para os organismos aquáticos. Este traba...
Anticancer drugs in the environment: Environmental levels and technological cha...
Valente, João Vasco; Coelho, Susana; Pastorinho, M. Ramiro; Sousa, Ana Catarina A.Cytostatic drugs are one of the most used therapeutic agents to treat cancer. However, their high toxicity turns their handling and disposal into a matter of great concern. Upon administration, cytostatics are mainly excreted through urine either as conjugated or unconjugated forms. The oncology patient’s urine enters sewage system, reaching wastewater treatment plants (WWTP) that are unable to remove cytostati...
Chemical characterization and bioactive potential of Thymus × citriodorus (Pers...
Oliveira, Ana S.; Rolo, Joana; Gaspar, Carlos; Cavaleiro, Carlos; Salgueiro, Lígia; Palmeira-de-Oliveira, Rita; Ferraz, Celso; Coelho, SusanaEthnopharmacological relevance: Thymus × citriodorus (Pers.) Schreb. is an interspecific hybrid between Thymus pulegioides and Thymus vulgaris, known for its pharmacological activities as diaphoretic, deodorant, antiseptic and disinfectant, the last mostly related with its antimicrobial activity. The folk use of other extracts, as hydrolates, have also been disseminated, as regulators of oily skin with anti-acn...

Toxicological characterization of supported ionic liquids for the removal of no...
Valente, João Vasco; Barros, Rafael; Coelho, Susana; Cristovão, Ana Clara; Pastorinho, M. Ramiro; Rocha, Luciana S.; Neves, Márcia C.; Freire, Mara G.Non-steroidal anti-inflammatory drugs (NSAIDs) are a class of widely used pharmaceuticals that has been detected in the aquatic environment. Due to their deleterious environmental and health concerns associated with “boomerang” effect, several technologies have been proposed to prevent their release into the environment. In this work, new ionic liquid-based materials were used to remove NSAIDs from aqueous solu...
Phyto- and zooplankton dynamics in two ICOLLs from Southern Portugal
Gamito, Sofia; Coelho, Susana; Perez-Ruzafa, AngelFoz do Almargem and Salgados are two small, intermittently closed and open lakes and lagoons (ICOLLs) located in the Portuguese southern coast, both remaining isolated from the sea throughout great part of the year. Based on environmental and biotic parameters, the first lagoon was classified as mesotrophic, with a greater marine influence, while the second one was classified as hypereutrophic. The plankton rel...
Comparative analysis of simulated root canal anatomy after different preparatio...
Coelho, SusanaINTRODUCTION: Evolution of endodontic shaping instruments has occurred over time, leading to improved materials, reduced procedural errors and preparation techniques with only minor alterations to the canal morphology. Although these new methods and instruments improvements, maintain the original canal anatomy still is a challenge. OBJECTIVES: The purpose of this study is to compare the shaping abilities of two...
Burkholderia pseudomallei: first case of melioidosis in Portugal
Pelerito, Ana; Nunes, Alexandra; Coelho, Susana; Piedade, Cátia; Paixão, Paulo; Cordeiro, Rita; Sampaio, Daniel A.; Vieira, Luís; Gomes, João PauloBurkholderia pseudomallei is a Gram-negative bacillus and the causative agent of melioidosis, a serious infection associated with high mortality rate in humans. It can be naturally found as an environmental saprophyte in soil or stagnant water, and rice paddies that predominate in regions of endemicity such as Northeast Thailand. B. pseudomallei is a Biosafety Level 3 organism due to risks of aerosolization and...
