Targeting Skin Aging Hallmarks In Vitro: Antioxidant, Anti-Inflammatory, and An...
Marques, Mário Pedro; Landim, Euclides; Varela, Carla; Costa, Ricardo M. F. da; Marques, Joana; Carvalho, Luís A. E. Batista de; Silva, AnaPlant-based extracts are rich sources of phenolic compounds, which may act as skin antiaging mediators. Herein, Cistus albidus L. (Ca), Cistus ladanifer L. subsp. ladanifer (Cl) and Cistus salviifolius L. (Cs) were selected to test whether their phytochemical profile and bioactive potential align to target human skin aging. Hydroethanolic extracts (HEs) were prepared and characterized using infrared vibrational...
O efeito do cyber abuso no bem-estar de jovens em Portugal
Marques, JoanaO bem-estar global e a saúde mental englobam o estado emocional, psicológico e social do indivíduo, refletindo-se na forma como este lida com o stress, as emoções, os desafios e as adversidades do quotidiano. Esta é uma dimensão complexa, que abrange desde experiências relacionais e traumas precoces até perturbações mentais diagnosticáveis, como a ansiedade e a depressão. A saúde mental está intrinsecamente lig...
A Spectrochemically Driven Study: Identifying Phenolic-Rich Extracts from Helic...
Marques, Mário Pedro; Landim, Euclides; Varela, Carla; Costa, Ricardo M. F. da; Marques, Joana; Carvalho, Luís A. E. Batista de; Silva, AnaPlants inhabiting mediterranean-influenced climatic zones, like Helichrysum stoechas (L.) Moench subsp. stoechas, Lavandula pedunculata (Mill.) Cav., and Thymus mastichina (L.) L. subsp. mastichina, have been scarcely investigated regarding their richness in phenolic compounds, herein explored as sources of skin anti-aging compounds. In this investigation, Fourier transform infrared spectroscopy (FTIR) in atten...
Late peritoneal leakage due to an abdominal wall defect
Burillo Simões, Pilar; Curto, Andreia; Marques, Joana; Fernandes, Vasco; Ferreira, Ana Carina; Gomes, Fernanda; Marques, Teresa; Jorge, CristinaPublisher Copyright: © 2025, Registre de Dialyse Peritoneale de Langue Francaise. All rights reserved.; Dialysate leakage is a complication of peritoneal dialysis with a 5% incidence rate. Late leaks are rare, and symptoms are subtle, as fluid loss occurs most often through abdominal wall defects. An 83-year-old diabetic woman was started on automated peritoneal dialysis one month after catheter placement. Thre...

Cold atmospheric plasma activation of human gingival fibroblasts for improved w...
Silva, Neusa; Marques, Joana; Brito da Cruz, Mariana; Luis, Henrique; Mata, António; Sério, SusanaSoft tissue regeneration plays a crucial role after oral surgery, as the successful healing of the soft tissue is a primary indicator of an efficacious intervention. Cold atmospheric plasma (CAP) has recently emerged as a promising therapeutic modality, exhibiting notable effects on cell migration and proliferation. Despite its potential, the dental application of CAP remains underexplored. This in vitro study ...
eBryoSoil: a citizen science application to monitor changes in soil ecosystems
Mira, André F.; Hortal, Joaquín; Portela, Ana Paula; Albertos, Belén; Estébanez, Belén; Branquinho, Cristina; Vieira, Cristiana; Hespanhol, HelenaBiological soil covers (BSCs) play a pivotal role in ecosystem functioning by enhancing soil stability, mediating nutrient cycling, and influencing soil hydrology. Recognized as ecosystem engineers, they can physically modify, maintain, or create habitats, facilitating plant community development. Through these intricate interactions, BSCs contribute significantly to ecological processes, highlighting their imp...
Hyaluronic acid-based gels for oral application: comparison of in vitro effects...
Marques, Ana Filipa Silva; Silva, Neusa; Brito da Cruz, Mariana; Marques, Joana; Mata, AntónioPurpose: This study aimed to evaluate the cytotoxic effects of different topical hyaluronic acid-based gels on human gingival fibroblasts and oral bacteria. Methods: Four different hyaluronate gels - Bexident® Aftas (BA), GUM® AftaClear (AfC), Gengigel®(G), Aloclair® Plus (AlC) and a chlorhexidine gel - Bexident®Gums(BG) were selected. Human gingival fibroblasts (HGF) were seeded in 48-well plates with differen...
A Non-Conventional Platinum Drug against a Non-Small Cell Lung Cancer Line
Silva, Jéssica D.; Marques, Joana; Santos, Inês P.; Carvalho, Ana L. M. Batista de; Martins, Clara B.; Laginha, Raquel; Batista de Carvalho, Luís A. E.A dinuclear Pt(II) complex with putrescine as bridging polyamine ligand ([Pt2Put2(NH3)4]Cl4) was synthesized and assessed as to its potential anticancer activity against a human non-small cell lung cancer line (A549), as well as towards non-cancer cells (BEAS-2B). This effect was evaluated through in vitro cytotoxicity assays (MTT and SRB) coupled to microFTIR and microRaman spectroscopies, the former deliverin...
Evaluation of the Cytotoxic Effect of Pd2Spm against Prostate Cancer through Vi...
Laginha, Raquel C.; Martins, Clara B.; Brandão, Ana L.; Marques, Joana; Marques, M. P.aula M.; Batista de Carvalho, Luís A. E.; Santos, Inês P.Regarding the development of new antineoplastic agents, with a view to assess the selective antitumoral potential which aims at causing irreversible damage to cancer cells while preserving the integrity of their healthy counterparts, it is essential to evaluate the cytotoxic effects in both healthy and malignant human cell lines. In this study, a complex with two Pd(II) centers linked by the biogenic polyamine ...
