Potential of solid-state fermentation to enhance the nutritional value of oilse...
Sousa, Daniel; Moset, Verónica; López-Luján, María del Carmen; Salgado, José Manuel Seara; Dias, Alberto Carlos Pires; Belo, Isabel; Pascual, Juan JoséThe objective of this study was to evaluate the potential of solid-state fermentation (SSF) to enhance the nutritional value of oilseed cakes (OC) for poultry. To this end, firstly, we characterized the main nutrients and antinutritional factors in non-fermented OC and fermented OC, as well as in fermented and extracted OC, from where enzymatic extracts were recovered. The fermented and extracted OC represented...
Opuntia ficus-indica fruit: a systematic review of its phytochemicals and pharm...
Giraldo-Silva, Luis; Ferreira, Bárbara; Rosa, Eduardo; Dias, Alberto Carlos PiresThe use of <i>Opuntia ficus-indica</i> fruits in the agro-food sector is increasing for a multiplicity of players. This renewed interest is, in part, due to its organoleptic characteristics, nutritional value and health benefits. Furthermore, industries from different sectors intend to make use of its vast array of metabolites to be used in different fields. This trend represents an economic growth opportunity ...
Evaluation of biotechnological processing through solid-state fermentation of o...
Sousa, Daniel; Simões, Luara Aparecida; Oliveira, Rui Pedro Soares de; Salgado, José Manuel Seara; Cambra-López, Maria; Belo, IsabelOilseed cakes (OC) are natural sources of lignocellulosic biomass, produced every year in large amounts. In addition to their main applications as animal feed, plant or soil fertilizer, and compost, they present enormous potential for being used in biotechnological processes for the obtainment and extraction of valuable bioactive compounds. This work evaluated the effect of solid-state fermentation on the bioac...
Microalgae and cyanobacteria as sources of bioactive compounds for cosmetic app...
Castro, Vera; Oliveira, Rui Pedro Soares de; Dias, Alberto Carlos PiresMicroalgae and cyanobacteria are rich in compounds with a wide diversity of biological activities that can be used to create new products with promising applications by the cosmetic industry. Many studies evaluating the bioactivities of microalgae and cyanobacteria extracts have been published, however perception of their potential use in cosmetic applications is still limited. The objective of this study was t...
Degradation of lignocellulosic matrix of oilseed cakes by solid-state fermentat...
Sousa, Daniel; Salgado, José Manuel Seara; Cambra-López, Maria; Dias, Alberto Carlos Pires; Belo, IsabelVegetable oils are yearly produced in large amounts generating solid by-products, the oilseed cake (OC). OCs are lignocellulosic materials that have been used for animal feed with some limitations due to high fibre content from the plant cell walls. Biotechnological processes can help to overcome these limitations and contribute to up-grading such by-products, enhancing their nutritional value as feed ingredien...
Comparative studies on the anti-neuroinflammatory and antioxidant activities of...
Magalhães, Vanessa; Silva, Ana Rita; Silva, Bruna; Zhang, Xiaoying; Dias, Alberto Carlos PiresGoji berries have several bioactivities and are consumed as food or used in folk medicine. In this study, the methanolic extracts from red and black goji berries were compared regarding their anti-inflammatory and antioxidant activities. Black goji berries extract has revealed significantly higher anti-inflammatory activity, in either biochemical assays or via decreasing the release of nitric oxide and inhibiti...
Protection against paraquat-induced oxidative stress by Curcuma longa extract-l...
Teixeira, Ana; Sárria, Marisa P.; Pinto, Inês; Espiña, Begoña; Gomes, Andreia C; Dias, Alberto Carlos PiresThe link between oxidative stress and environmental factors plays an important role in chronic degenerative diseases; therefore, exogenous antioxidants could be an effective alternative to combat disease progression and/or most significant symptoms. <i>Curcuma longa</i> L. (CL), commonly known as turmeric, is mostly composed of curcumin, a multivalent molecule described as having antioxidant, anti-inflammatory ...
Hypericum perforatum and Its potential antiplatelet effect
Monteiro, Maria-do-Céu; Dias, Alberto Carlos Pires; Costa, Daniela; Almeida-Dias, António; Criado, Maria BegoñaBackground: <i>Hypericum perforatum</i> (HP) is currently one of the most consumed medicinal plants in the world. In traditional Chinese medicine, the herb hypericum (<i>Guan Ye Lian Qiao</i>) belongs to the group of plants that clarify heat. It is also used to treat various types of infection and inflammation. In contrast to the extensive literature on the antidepressant effects of HP, little is known about it...
Neurotherapeutic effect of Hyptis spp. leaf extracts in Caenorhabditis elegans ...
Vilasboas-Campos, Daniela; Costa, Marta Daniela Araújo; Castro, Andreia Cristiana Teixeira; Rios, Rejaine; Silva, Fabiano Guimarães; Bessa, CarlosHyptis suaveolens (HS), Hyptis pectinata (HP) and Hyptis marrubioides (HM) are plants used in folk medicine for treatment of several diseases. Here, we tested the in vivo antioxidant and neuroprotective potential of methanolic extracts from these plants, containing several rosmarinic acid derivatives and isoquercetin. In C. elegans, HS, HP and HM leaf extracts enhanced the antioxidant responses through the indu...
Comparison of the protective effects of ginsenosides Rb1 and Rg1 on improving c...
Yang, Yujie; Li, Shanshan; Huang, Hong; Lv, Jingwei; Chen, Shanguang; Dias, Alberto Carlos Pires; Li, Yujiao; Liu, Xinmin; Wang, QiongThis present study was designed to investigate the different effects of ginsenosides Rb1 and Rg1 on improving cognitive deficits in 4-month-old SAMP8 mice. Mice were divided into six groups, including the SAMP8 group, the SAMP8 + Donepezil (1.6 mg/kg) group, the SAMP8 + Rb1 (30 and 60 µmol/kg), and SAMP8 + Rg1 (30 and 60 µmol/kg) groups. SAMR1 mice of the same age were used as the control group. Ginsenosides an...
