Usage of thermal spring water for optimal skin health: bridging traditional the...
Rocha, Pedro Emanuel; Alves, Maria José; Fidalgo, Cátia; Correia, Daniela; Pedrosa, Silvia; Madureira, Ana RaquelThermal spring waters (TSW) have been employed forntherapeutic purposes across the centuries being increasingly recognized for its unique benefits in skin health, in which immunomodulatory effects play a crucial role. By reviewing the literature, the multifaceted properties of TSW, which arise from its diverse mineral composition as well as its thermal characteristics, revealed the strong potential of these wat...
Exploring the Impact of Ultrasound-Assisted Extraction on the Phytochemical Com...
Gouvinhas, Irene; Saavedra, Maria José; Alves, Maria José; Garcia, JulianaThe health benefits of Tamus communis fruits have been associated with their high phenolic content, which comprises several flavonoids. However, the extraction methods might significantly impact these valuable compounds' bioactivity. Therefore, the current study assesses how different extraction techniques affect T. communis extracts' antioxidant, anti-aging, antimicrobial, cytotoxic, anti-inflammatory, and phe...
Unlocking Nature’s Anti-Aging Secrets: The Potential of Natural Mineral Waters ...
Gama, Ana Rita; Gomes, Carolina P.; Caetano, Cátia; Oliveira, Ana Sofia; Rolo, Joana; Barros, Lillian; Plasencia, Paula; Garcia, JulianaSkin aging is influenced by intrinsic and extrinsic factors, leading to structural changes in the skin. Current anti-aging cosmetic trends emphasize innovative natural ingredients, including plant extracts, thermal waters, and botanical hydrolats. This work aims to develop six natural anti-aging cosmetics (two serums, two day creams, and two night creams) with innovative and non-irritating profiles. The rationa...
Unveiling the impact of thermal water in German chamomile infusions: effects on...
Silveira, Tayse F. F. da; Echegaray, Noemí; Guimarães, Rafaela; Lemos, André; Pires, Tânia C.S.P.; Ferreira, Isabel C.F.R.; Alves, Maria JoséGerman chamomile (GC) and thermal water (TW) are widely known for their biological properties. This study explored whether combining GC with TW could promote an improvement in the bioactivities of GC infusions compared to using drinking water (DW). DW was tested at 100 ◦C (GC-100DW) and TW at both 100 ◦C (GC-100TW) and 60 ◦C (GC-60TW). The use of TW for preparing infusions was associated with the reduction of t...
Natural Mineral Water–Plant Extract Combinations as Potential Anti-Aging Ingred...
Gomes, Carolina P.; Oliveira, Ana S.; Rolo, Joana; Silveira, Tayse F. F. da; Palmeira de Oliveira, Rita; Alves, Maria José; Plasencia, PaulaNatural mineral waters (NMWs) and plant extracts have long been valued for their therapeutic properties and skin benefits. This study investigated, in vitro, the role of five Portuguese NMWs (A-E), combined with plant extracts from five species (Ficus carica L., Rubus idaeus L., Vaccinium myrtillus, Cistus ladanifer and Thymus x citriodorus) as bioactive ingredients. Antioxidant capacity was assessed using the ...
Classical Versus Wellness Thermalism: The Case of Portuguese Thermal Establishm...
Alcina Nunes; Jéssica Alves; Estelle Gonçalves; Ana Margarida Pereira; Maria José Alves; Nunes, Alcina; Alves, Maria JoséThermal/mineral springs are one of the fastest-growing subcategories of wellness tourism. Indeed, it is an activity that has steadily increased in all of Europe’s developed economies over the last few decades. The pandemic has raised awareness of the importance of healthy lifestyles and has subsequently led to a surge in consumption of experiences and travel, somehow motivated by wellness. This study analyses t...
Biomonitoring of firefighters' exposure to priority pollutant metal(loid)s duri...
Paiva, Ana Margarida; Barros, Bela; Azevedo, Rui; Oliveira, Marta; Alves, Sara Elisa Brás; Esteves, Filipa; Fernandes, Adília; Vaz, Josiana A.Wildland firefighters are exposed to metal(loid)s released during wildfires through vegetation combustion, which also promotes remobilization of accumulated anthropogenic metal(loid)s. Studies biomonitoring metal(loid)s exposure promoted exclusively by wildfire suppression activities are lacking. This work aimed to characterize, for the first time, the impact of real-life wildland firefighting operations on uri...
Jatoba (Hymenaea courbaril L.) Pod Residue: A Source of Phenolic Compounds as V...
Del Angelo, Gabriela Lucca; Oliveira, Isabela Silva de; Albuquerque, Bianca R.; Kagueyama, Samanta Shiraishi; Silva, Tamires Barlati VieiraThis study aimed at investigating the chemical composition and a selected group of bioactivities of jatoba (Hymenaea courbaril L.) pod residue. An aqueous extract (deionized water; AE) and a hydroethanolic extract (ethanol: deionized water, 70:30 v/v; ETOH) were obtained via maceration. Ten phenolic compounds were characterized via LC-DAD-ESI/MSn: seven procyanidins, two quercetin derivatives and one taxifolin ...
The Impact of Sleep on Haematological Parameters in Firefighters
Alves, Sara Elisa Brás; Silva, Francisca; Esteves, Filipa; Costa, Solange; Slezakova, Klara; Alves, Maria José; Pereira, Maria do CarmoSleep is a vital process that impacts biological functions such as cell renewal, bone regeneration, and immune system support. Disrupted sleep can interrupt erythropoiesis, leading to fewer red blood cells, reduced haemoglobin concentration, and decreased haematocrit levels, potentially contributing to haematological disorders. This is particularly concerning for shift workers for example firefighters. While pr...
Harnessing the power of natural mineral waters in bread formulations: effects o...
Ferreira, Fernanda; Guimarães, Rafaela; Lemos, André; Milho, Catarina; Silveira, Tayse F. F. da; Ueda, Jonata M.; Carocho, Márcio; Heleno, Sandrina A.This study aimed to evaluate the feasibility of incorporating natural mineral waters (NMW), including thermal water (TW) and bottled mineral water (BMW), into bread (‘biju’ type) to enhance its mineral content and explore their impacts on physicochemical, technological, biochemical, and chemical composition. NMW, rich in sodium, potassium, and magnesium, resulted in bread formulations with higher contents of th...
