Ultrasound-guided genicular nerve radiofrequency ablation

Caroço, Tomás; Leoni, Giovanni; Teixeira, Daniela; Ribeiro, Jorge; Paiva, Bruno; Barbosa, Jorge

Publisher Copyright: © 2025 The Authors.; Radiofrequency ablation (RFA) of the knee joint may be an effective therapeutic option for the management of chronic knee pain. Accurate anatomical knowledge is essential for optimizing the precision and outcomes of the procedure. The innervation of the knee joint is complex. Ultrasound (US) guidance offers a widely accessible method for targeting sensory nerves. Given ...


Mycotoxins in Raw Bovine Milk: UHPLC-QTrap-MS/MS Method as a Biosafety Control ...

Leite, Marta; Freitas, Andreia; Barbosa, Jorge; Ramos, Fernando

Mycotoxins are compounds produced by several fungi that contaminate agricultural fields and, either directly or by carry-over, final food products. Animal exposure to these compounds through contaminated feed can lead to their excretion into milk, posing threats to public health. Currently, aflatoxin M1 is the sole mycotoxin with a maximum level set in milk by the European Union, as well as the most studied. No...


Pharmaceuticals in Coastal Waters: An UHPLC-TOF-MS Multi-Residue Approach

Leston, Sara; Freitas, Andreia; Rosa, João; Vila Pouca, Ana Sofia; Barbosa, Jorge; Reis-Santos, Patrick; Fonseca, Vanessa F.; Pardal, Miguel

Anthropogenic chemical contamination represents a key stressor of natural environments with pharmaceuticals comprising a particular group of emerging pollutants with the potential to induce biological responses in non-target organisms. Therefore, an analytical method based on ultra-high-performance liquid chromatography coupled to time-of-flight tandem mass spectrometry (UHPLC-TOF-MS) was developed for estuarin...


Regulated and Emerging Mycotoxins in Bulk Raw Milk: What Is the Human Risk?

Leite, Marta; Freitas, Andreia; Barbosa, Jorge; Ramos, Fernando

Mycotoxins are abiotic hazards whose contamination occurs at the pre- and post-harvest stages of the maize value chain, with animal exposure through contaminated feed leading to their excretion into milk. Currently, only aflatoxin M1 is regulated in milk products. Since feed materials and complete feed present a multi-mycotoxin composition and are the main mycotoxin source into milk, it is important to recogniz...


Comprehensive assessment of different extraction methodologies for optimization...

Leite, Marta; Freitas, Andreia; Barbosa, Jorge; Ramos, Fernando

A multi-analyte method for identification and quantification of 23 regulated and emerging mycotoxins was devel- oped in maize samples by ultra high-performance liquid chromatography coupled to tandem mass spectrometry (UHPLC-MS/MS). Several extraction methodologies were evaluated, including solid-liquid extraction (SLE), solid- phase extraction (SPE), and modified QuEChERS (Quick, Easy, Cheap, Effective, Rugged...


Mycotoxins and Maize Value Chain: Multi-Matrix and Multi-Analyte Tools towards ...

Leite, Marta; Freitas, Andreia; Barbosa, Jorge; Ramos, Fernando

Maize value chains represent invaluable end-consumer products in food systems worldwide. Mycotoxin contamination along these chains causes severe economic and health impacts from the plant, animal and human safety points of view. This work aimed to develop a single standardized methodology that fulfilled extraction and detection procedures for 22 mycotoxins in maize chain matrices. The main goal concerned the v...


UHPLC-ToF-MS as a High-Resolution Mass Spectrometry Tool for Veterinary Drug Qu...

Leite, Marta; Marques, Ana Rita; Vila Pouca, Ana Sofia; Barros, Sílvia; Barbosa, Jorge; Ramos, Fernando; Afonso, Isabel Maria; Freitas, Andreia

Milk is one of the most widely consumed foods in the world, despite the increasing consumption of plant-based alternatives. Although rich in nutrients and believed by consumers to be free of undesirable contaminants, milk, whether of animal or plant origin, is not always free from residues of chemical substances, including veterinary medicines. For instance, in intensive livestock production, antibiotics are of...


Service-Learning Projects (S-L): the contribution and perspective of partners

Silva, Catarina Raposo Vieira da; Monteiro, Daniela; Barbosa, Jorge

This abstract focuses on the experiences and benefits identified by the partner organisations of different Service Learning (S-L) projects developed in the course units of Social Work degrees of the Catholic University of Portugal located in Braga and Lisbon. The educational experiences were developed in ten social economy organisations, namely in the areas of ageing, education, social inclusion, disability, ru...

Entre a estrutura social e a ação humana : práticas reflexivas do serviço socia...

Barbosa, Jorge

Intervenção Social. ISSN 0874-1611. N. 57-58 (2021).; Neste artigo discutimos os propósitos da aplicação dos elementos da “teoria da estruturação”, no estudo empírico do agir profissional dos assistentes sociais na efetivação dos direitos de cidadania em saúde na sociedade neoliberal contemporânea. Partindo de um pequeno estudo bibliográfico, exploratório e sintético, ancorado nas etapas da revisão da literatur...
