Mining activities may affect the health of miners and communities living near mining sites, these effects persist even when mine is abandoned. During processes various toxic wastes are produced released into surrounding environment, resulting in contamination air, drinking water, rivers, plants, soils. In a geochemical sampling campaign undertaken Panasqueira Mine area central Portugal, an anomalous distribution several metals arsenic (As) was identified environmental media. Several...
Abstract BACKGROUND The olive oil industry generates significant amounts of semi‐solid wastes, namely pomace. Olive pomace is a by‐product rich in high‐value compounds (e.g. dietary fibre, unsaturated fatty acids, polyphenols) widely explored to obtain new food ingredients. However, conventional extraction methods frequently use organic solvents, while novel eco‐friendly techniques have high operational costs. development powdered products without any step has been proposed as more feasible...
The prebiotic potential of fructo-oligosaccharides (microbial-FOS) produced by a newly isolated Aspergillus ibericus, and purified Saccharomyces cerevisiae YIL162 W, was evaluated. Their chemical structure functionality were compared to non-microbial commercial FOS sample. Prebiotics fermented in vitro fecal microbiota five healthy volunteers. Microbial-FOS significantly stimulated the growth Bifidobacterium probiotic strains, triggering beneficial effect on gut composition. A higher amount...
Tomato by-products from processing industries have a higher potential to be reused as source of bioactive compounds. Reliable national data on tomato and physicochemical characterisation that will inform find effective planning waste management in Portugal is absent. To help obtain this knowledge, selected companies were recruited representative samples generation, composition was evaluated. Furthermore, an environmental-friendly method (the ohmic heating (OH) method, which allows the...
O conhecimento aprofundado das variações anatômicas na drenagem venosa superficial do corpo humano é essencial para práticas clínicas e cirúrgicas de precisão. Neste estudo caso, foi identificada a presença da veia safena anterior no segmento perna direita um cadáver masculino proveniente laboratório anatomia humana UEA. Segundo literatura, magna geralmente se origina união entre o arco venoso dorsal pé digital medial hálux. No entanto, sistema dos membros inferiores notoriamente complexo,...
O artigo apresenta uma revisão integrativa da literatura sobre a cirurgia robótica no tratamento do câncer colorretal, destacando que, embora essa técnica oferece inovações tecnológicas significativas—como visão tridimensional, maior precisão, instrumentos articulados e ergonomia superior—e vantagens em cenários desafiadores (por exemplo, pelves estreitas pacientes obesos), os resultados oncológicos funcionais, tanto curto quanto longo prazo, tendem ser comparáveis aos obtidos com...
Buscar compreender o conceito de Gestão democrática, sua importância como um modelo gestão que visa incorporar na escola princípio democracia em forma mais legitima ser compreendida, pois possibilita a construção e pratica uma proposta pedagógica permite participação dos envolvidos escola. E esta seja para além resoluções problemas, ou tomadas decisões. A democrática deve descentralização do poder, da dissolução autoritarismo no ambiente escolar, permitindo com através suas práticas possa...
Usually, wine-making by-products are discarded, presenting a significant environmental impact. However, they can be used as source of bioactive compounds. Moreover, consumers' increasing demand for naturally nutritious and healthy products requires new formulations food product improvement, together with sustainable, environmentally friendly extraction methods. Thus, this work aimed to compare ohmic heating (OH) conventional methodology (CONV), using food-grade solvents, mainly water,...
In times of pandemic and when sustainability is in vogue, the use byproducts, such as fiber-rich tomato can be an asset. There are still no studies on impact extraction methodologies gastrointestinal tract action bioactive properties. Thus, this study used a solid fraction obtained after conventional method (SFCONV) ohmic (SFOH) to analyze effect compounds (BC) bioactivities. Results showed that SFOH presents higher total fiber than SFCONV samples, 62.47 ± 1.24–59.06 0.67 g/100 g DW,...
The by-products of the winemaking process can represent chances for development new products. This study focused on “zero waste” strategy generated within from white and red grape varieties cultivated in north Portugal. phytochemical properties were identified characterized. Ohmic heating (OH) as a green extraction method was also applied to pomace due their unknown effects centesimal compositions. Both protein carbohydrates shown be higher bagasse than stems. Additionally, is richer...
Formaldehyde (FA) is a widely used industrial chemical for which exposure associated with nasopharyngeal and sinonasal cancer. Based on sufficient evidence of carcinogenicity from human investigations, supporting studies mechanisms underlying carcinogenesis, experimental in animals, FA status was recently revised reclassified as carcinogen. The highest level to occurs occupational settings. Although several reported ability induce genotoxic responses exposed workers, not all findings were...
Fucus spp. seaweeds thrive in the cold temperate waters of northern hemisphere, specifically littoral and sublittoral regions along rocky shorelines. Moreover, they are known to be a rich source bioactive compounds. This study explored valorization spiralis through extraction bioactives polysaccharides (PSs) for food applications biostimulant use. The were extracted using microwave hydrodiffusion gravity (MHG), where condition 300 W 20 min resulted highest total phenolic content antioxidant...
Phenolic compounds are important bioactive identified in prickly pear peel that have antioxidant and antimicrobial properties. However, conventional thermal extraction methods may reduce their bioactivity, technologies such as high pressure (HP) ohmic heating (OH) help preserve them. In this study, both were analyzed, individually combined (250/500 MPa; 40/70 °C; ethanol concentration 30/70%), compared with Soxhlet regard to total phenolics, flavonoids, carotenoids well (ABTS, DPPH, ORAC),...
