LC-ESI-UHR-QqTOF-MS/MS profiling and anti-inflammatory potential of the cultiva...
Zeghbib, Walid; Boudjouan, Fares; Carneiro, João; Oliveira, Ana L. S.; Sousa, Sérgio F.; Pintado, Manuela Estevez; Ourabah, Asma; Vasconcelos, VitorOpuntia plants are abundant but still underexplored edible resources of the Algerian region. This work chemically characterizes extracts of different parts of the fruit of the commercial Opuntia ficus-indica (L.) Mill. and the wild Opuntia stricta (Haw.) Haw. growing in Bejaia, and evaluates their anti-inflammatory potential through different cell and cell-free bioassays. The LC-ESI-UHR-QqTOF-MS/MS analysis ena...
In vitro antimicrobial activity of volatile compounds from the Lichen Pseudever...
Essadki, Yasser; Hilmi, Adel; Cascajosa-Lira, Antonio; Girão, Mariana; Darrag, El Mehdi; Rosário Martins, Maria; Romane, AbderrahmaneLichens are symbiotic organisms with unique secondary metabolism. Various metabolites from lichens have shown antimicrobial activity. Nevertheless, very few studies have investigated the antimicrobial potential of the volatile compounds they produce. This study investigates the chemical composition and antimicrobial properties of volatile compounds from Pseudevernia furfuracea collected in two regions of Morocc...
Carotenoids from cyanobacteria modulate iNOS and inhibit the production of infl...
Morone, Janaína; Vasconcelos, Vitor; Hentschke, Guilherme; Rosário Martins, Maria; Pinto, Eugénia; Lopes, GracilianaCyanobacteria are green multiproduct refineries of increasing interest for different industrial prospects. In this work, eleven cyanobacteria strains isolated from the Cape Verde archipelago were explored for their biotechnological applications in the field of inflammation. A biorefinery approach was employed to produce carotenoidtargeted extracts, further profiled by HPLC-PDA and explored for their ability to ...
Exploring the bioactive potential of Pisolithus (Basidiomycota): comprehensive ...
S. Oliveira, Rui; Preto, Marco; Santos, Germana; Silva, Ana Margarida; Vasconcelos, Vitor; Martins, RosárioAddressing pressing health concerns, modern medical research seeks to identify new antimicrobials to combat drug resistance, novel molecules for cancer treatment, and antioxidants for inflammation-related diseases. Pisolithus (Basidiomycota) is a ubiquitous and widely distributed fungal genus in forest ecosystems, known for establishing ectomycorrhizal associations with a range of host plants, enhancing their g...
Microcystin-degrading bacteria reduce bioaccumulation in Fragaria vulgaris and ...
Haida, Mohammed; Khalloufi, Fatima El; Essadki, Yasser; Alexandrino, Diogo A. M.; Mugani, Richard; Hejjaj, Abdessamad; Campos, AlexandreIn Morocco, red fruit production has thrived, primarily utilizing hydroponic methods to control crops, increase fruit yield and quality, and avoid soil-related problems. However, the irrigation of these expansive hydroponic farms relies heavily on water sourced from dams, many of which are contaminated with Microcystins (MCs). To address this contamination issue, ongoing research is focused on discovering effec...
Tracing the path between mushrooms and Alzheimer’s Disease—a literature review
Silva, Ana Margarida; Preto, Marco; Grosso, Clara; Vieira, Mónica; Delerue-Matos, Cristina; Vasconcelos, Vitor; Reis, Mariana; Barros, LillianAlzheimer’s disease (AD) is well-known among neurodegenerative diseases for the decline of cognitive functions, making overall daily tasks difficult or impossible. The disease prevails as the most common form of dementia and remains without a well-defined etiology. Being considered a disease of multifactorial origin, current targeted treatments have only managed to reduce or control symptoms, and to date, only ...
Stalling the course of neurodegenerative diseases: could cyanobacteria constitu...
Ramos, Vitória; Reis, Mariana; Ferreira, Leonor; Silva, Ana Margarida; Ferraz, Ricardo; Vieira, Mónica; Vasconcelos, Vitor; Martins, RosárioNeurodegenerative diseases (NDs) are characterized by progressive and irreversible neuronal loss, accompanied by a range of pathological pathways, including aberrant protein aggregation, altered energy metabolism, excitotoxicity, inflammation, and oxidative stress. Some of the most common NDs include Alzheimer’s Disease (AD), Parkinson’s Disease (PD), Multiple Sclerosis (MS), Amyotrophic Lateral Sclerosis (ALS)...
Cyanobacteria-based bioprocess for cosmetic products—cyanobium sp. as a novel s...
Pagels, Fernando; Guedes, A. Catarina; Vicente, A. A.; Vasconcelos, VitorAs a producer of pigments with known bioactive potential, cyanobacteria are a great source of active ingredients for cosmetics (i.e., carotenoids and phycobiliproteins). Multiple phases in the cyanobacteria-based bioprocess led to the obtention of these compounds. The marine Cyanobium sp. LEGE 06113 has been proposed as a promising source for pigments for cosmetic uses, and it has been optimized in the past few...
Bioprospecting for industrially relevant exopolysaccharide-producing cyanobacte...
Cruz, José Diogo; Delattre, Cédric; Felpeto, Aldo Barreiro; Pereira, Hugo; Pierre, Guillaume; Morais, João; Petit, Emmanuel; Silva, JoanaCyanobacterial exopolysaccharides (EPS) are potential candidates for the production of sustainable biopolymers. Although the bioactive and physicochemical properties of cyanobacterial-based EPS are attractive, their commercial exploitation is limited by the high production costs. Bioprospecting and characterizing novel EPS-producing strains for industrially relevant conditions is key to facilitate their impleme...
Assessment of cyanobacterial biomass as sustainable agricultural fertilizer: so...
Massa, Anabella; Azevedo, Joana; Azevedo, Rui; Pinto, Edgar; Costa, Anabela; Vasconcelos, Vitor; Campos, Alexandre; Freitas, MarisaProviding food to the growing human population in a sustainable way is one of the greatest challenges of modern society. In this context, cyanobacterial biomass (CB) can function as a source of macronutrients to increase soil productivity. These organisms can be collected from the environment in considerable amounts, since they tend to grow in large blooms. However, some of these cyanobacterial strains produce ...
