Oral Salvia officinalis phenolics abolish mortality and mitigate inflammation i...
Direito, Rosa; Rocha, João; Melo, Inês Alves de; Gonçalves, Margarida; Duarte, Maria Paula; Fernandes, Adelaide; Sepodes, Bruno; Figueira, Maria-EduardoPublisher Copyright: © 2025; Background: This study is the first to evaluate a phenolic extract of Salvia officinalis in the TNBS murine model of colitis. Inflammatory bowel disease (IBD) involves transmural oxidative and nitrosative stress that up-regulates inducible nitric-oxide synthase (iNOS) and cyclo‑oxygenase-2 (COX-2). Although phenolic constituents of S. officinalis are anti-inflammatory in vitro, thei...

Panizio, Roberta; Castro, Carlos; Pacheco, Nuno; Assis, Ana Carolina; Longo, Andrei; Vilarinho, Cândida; Teixeira, José Carlos; Brito, Paulo© 2024 The Authors. Published by Elsevier Ltd.; This study investigates the thermochemical decomposition and gasification performance of biochars produced from blends of waste lignocellulosic biomass and waste insulation electrical cables at varying temperatures. Characterization tests revealed changes, particularly in ash content (27.5 %–34 %) and elemental composition, with nitrogen content increasing notably...
