Time-dependent accumulation of biogenic amines and microbial succession during ...
Ribeiro, Ana J.; Milheiro, Juliana; Nunes, Fernando M.; Carvalho, Teresa B. de; Barbosa, Joana B.; Silva, Filipe; Teixeira, Paula; Saraiva, Cristina M.Dry-aging of beef under controlled temperature, humidity and airflow reshapes the surface microbiota and may influence biogenic amine (BA) accumulation. In this study, culture-based enumeration, 16 S rRNA gene profiling of combined crust + inner meat, and validated HPLC quantification of BAs were integrated to track safety- and quality-relevant changes over 60 days. Sequencing showed Pseudomonadota and Bacillot...
Circular packaging under suspicion: The cat and mouse game with greenwashing
Lopes, João M.; Silva, Filipe; Gomes, Sofia; Nogueira, ElisabetePurpose – As consumers become increasingly savvy to deceptive marketing tactics such as greenwashing, the nexus between the desire to buy goods housed in circular packaging, environmental consciousness and the quest for pro-circular insights takes center stage in discussions surrounding conscientious and sustainable consumption. This study aims to evaluate how consumers’ perceptions of companies’ greenwashing b...
Dry-aged beef: a global review of meat quality traits, microbiome dynamics, saf...
Ribeiro, Ana J.; Silva, Filipe; Teixeira, Paula; Saraiva, Cristina M.Dry-aged beef is valued for its tenderness, complex aroma, and concentrated flavor. However, variability in aging protocols and limited understanding of underlying biological and technological processes can compromise consistent quality and safety. This review examines factors influencing meat characteristics, including genetics, breed, sex, age, diet, intramuscular fat deposition, antioxidant reserves, and end...
Short-pulse direct laser writing of 3Y-TZP zirconia: a superior surface modific...
Sahoo, Narayan; Carvalho, Óscar; Özcan, Mutlu; Eyüboğlu, Tan Fırat; Souza, Júlio C. M.; Silva, Filipe; Henriques, BrunoThe clinical success of zirconia-based restorations relies on surface modifications that enhance adhesion without compromising material integrity. This study evaluates Direct Laser Writing (DLW) as a non-contact, contamination-free alternative to conventional grit-blasting methods (alumina particle abrasion [SB] and silica-coated alumina treatment [SC]. Surface roughness (Ra), wettability, surface free energy (...
Molecular and serological screening support the lack of Coxiella burnetii circu...
Loureiro, Filipa; Mesquita, João R.; Cardoso, Luis; Pintado, Cristina Santos; Gonçalves, S. Gomes; Matos, Ana; Soeiro, V.; Gonçalves, A.; Silva, FilipeCoxiella burnetii is a highly infectious zoonotic pathogenic bacterium that has a major economic impact in the livestock industry throughout the world and causes unpredictable outbreaks in humans worldwide. Although it is known that birds are potential reservoirs of C. burnetii, their role in the epidemiological cycle of the pathogen has not been fully verified. Due to its non-specific symptoms and clinical sig...
Mineral profile, oxidative stability and color traits in dry aged meat: integra...
Ribeiro, Ana J.; Braga, Fernando G.; Oliveira, Irene; Silva, Filipe; Teixeira, Paula; Saraiva, Cristina M.Dry aging enhances beef's sensory quality, but the role of trace-element dynamics in driving physicochemical changes remains unclear. We dry-aged Longissimus lumborum loins (n = 12) for 60 days, sampling on days 1, 14, 35 and 60. Essential (Ca, K, Na, Mg, Fe, Se, Cr, Zn, Cu) and toxic (As, Cd, Co, Pb) elements were quantified by GF-AAS/FAAS; pH and L?, a?, b? color were measured with standard probes; lipid oxid...
Assessment of Antibiotic Resistance Among Isolates of Klebsiella spp. and Raoul...
Sabença, Carolina; de la Rivière, Rani; Barros, Paulo; Cabral, João Alexandre; Sargo, Roberto; Sousa, Luís; Dapkevicius, Maria de Lurdes EnesOne of the significant challenges facing modern medicine is the rising rate of antibiotic resistance, which impacts public health, animal health, and environmental preservation. Evaluating antibiotic resistance in wildlife and their environments is crucial, as it offers essential insights into the dynamics of resistance patterns and promotes strategies for monitoring, prevention, and intervention. and genera is...
Multi-scale laser micropatterning of dental zirconia(3Y-TZP) for enhanced adhes...
Sahoo, Narayan; Carvalho, Oscar; Özcan, Mutlu; Silva, Filipe; Lasagni, Andrés-Fabian; Henriques, BrunoZirconia (3Y-TZP) is a highly valued material in dentistry due to its exceptional mechanical strength, biocompatibility, and aesthetic appeal, making it ideal for crowns, bridges, and implants. However, achieving strong adhesion to zirconia is challenging because of its chemical inertness and low surface energy, which prevent effective bonding with traditional dental cements[1-3]. This study evaluated the impac...
Body Condition in Small Ruminants—Effects of Nutrition on the Hypothalamic–Pitu...
Chaves, Ana Sofia; Silva, Filipe; Valentim, Ramiro; Quintas, HelderNutritional status plays a vital role in regulating ovary activity. This regulation is mediated by the hypothalamus–pituitary–gonad axis and by effects exerted directly on the ovary. Therefore, to achieve the best reproductive performance, it is essential to know how the nutritional status affects the secretion of GnRH, gonadotrophins, and sex steroid hormones. Adequate body reserves and energy balance are crit...
Laser-texturing and traditional surface modification to improve the adhesion of...
Fernandes, Valter; Carvalho, Oscar; Silva, Filipe; Henriques, Bruno; Özcan, Mutlu; Souza, Júlio C. M.Objectives The aim of this study was to perform experimental evaluation of the synergistic effects of laser-texturing and different traditional surface modification approaches to improve the push-out bond strength of glass fiber-reinforced composite (GFRC) posts to resin-matrix cements used in endodontically treated teeth rehabilitation. Methods One hundred and ten freshly extracted mandibular single-rooted pre...
