Seasonal biochemical variations in mediterranean halophytes and salt-tolerant p...
Oliveira, Marta; Guerreiro Pereira, Catarina Alexandra; Castañeda-Loaiza, Viana; Rodrigues, Maria João; Neng, Nuno R.; Hoste, Hervé; Hamed, Karim BenClimate change intensifies water scarcity and soil salinization, threatening agriculture and livestock systems, especially in arid Mediterranean regions. Halophytes and salt-tolerant plants offer sustainable alternatives to support ruminant health and productivity where traditional crops fail, helping mitigate climate impacts. This work evaluated seasonality effects on the biochemical properties, including prox...

From threat to opportunity: Harnessing the invasive Carpobrotus edulis (L.) N.E...
Pereira, Catarina Guerreiro; Neng, Nuno R.; Custódio, LuísaCarpobrotus edulis (L.) N.E.Br. (Hottentot-fig) is a problematic invasive species found in coastal areas worldwide. Mechanical removal is a common control method, leaving the removed biomass available as a possible source of natural phytochemicals with prospective commercial applications. While the Hottentot-fig’s vegetative organs have been studied previously, this work establishes for the first time a seasona...
An accurate and precise liquid chromatography–tandem mass spectrometry method f...
Maria, Marisa; Neng, Nuno R.; Berg, ThomasAlcohol consumption is associated with a wide risk of different diseases, injury and death, and has significant social and economic consequences worldwide. Phosphatidylethanol (PEth) is a group of promising direct alcohol biomarkers, with a significantly longer half-life in blood than ethanol, which can be measured to predict different drinking patterns, such as heavy- and social drinking. This study aimed to d...
Simple analytical strategy for screening three synthetic cathinones (α-PVT, α-P...
Segurado, André M.; Ahmad, Samir M.; Neng, Nuno R.; Maniés-Sequeira, Margarida M.; Gaspar, Helena; Nogueira, José Manuel F.Synthetic cathinones are analogue compounds of the plant based stimulant cathinone. Its use, abuse, and related consumption complications have steadily increased in the last years. For this reason, there is a need for innovative analytical approaches that enable its rapid screening in biological matrices (e.g., oral fluids). The present work proposes a new analytical methodology by combining bar adsorptive micr...
Application of bar adsorptive microextraction for the determination of levels o...
Oliveira, Mariana N.; Gonçalves, Oriana C.; Ahmad, Samir M.; Schneider, Jaderson K.; Krause, Laiza C.; Neng, Nuno R.; Caramão, Elina B.This work entailed the development, optimization, validation, and application of a novel analytical approach, using the bar adsorptive microextraction technique (BAμE), for the determination of the six most common tricyclic antidepressants (TCAs; amitriptyline, mianserin, trimipramine, imipramine, mirtazapine and dosulepin) in urine matrices. To achieve this goal, we employed, for the first time, new generation...
Seasonal variations of the nutritive value and phytotherapeutic potential of Cl...
Oliveira, Marta; Rodrigues, Maria João; Neng, Nuno R.; Nogueira, José Manuel Florêncio; Bessa, R.J.B.; Custódio, LuísaIn our endeavor to identify salt-tolerant plants with potential veterinary uses in ruminants’ production strategies, we focused on Cladium mariscus L. Pohl (sawgrass), due to its high total phenolic and tannin content, anti-radical properties, and ethnomedicinal uses. Aerial parts were collected along the year in Southern Portugal and evaluated for the nutritional profile and in vitro organic matter digestibili...
