A short-term study was performed to assess the effects of diets supplemented with polyphenols (CSVP), extracted from the chestnut (Castanea sativa) shell, agri-food waste rich in tannins, and mullein (Verbascum macrurum), a perennial spontaneous plant rich in flavonoids, on a zebrafish (Danio rerio) model of k-carrageenan-induced intestinal inflammation. Morphological asset of intestine, immunoden ...
... Global interest in phytogenic feed additives as alternatives to antibiotics in feed has been spurred by the banning of antibiotic growth promoters by several countries. Suitable plant extracts for development of phytogenic feed additives should have therapeutic value and should also be safe. The aim of this study was to evaluate the antibacterial, antioxidant and anti-lipoxygenase activities as we ...
... Marine biological fouling has caused huge economic losses and environmental problems. Therefore, it was essential to develop effectively environment-friendly biofouling resistance technology. Here, inspired by the natural module of bacterial secretions, animal and plant extracts, we synthesized Schiff based compounds through Tobramycin (TOB) from Streptomyces and Protocatechualdehyde (PR) from bla ...
... This work aims to investigate antifungal, mycotoxin inhibitory efficacy of the hop essential oil (HEO) nanoemulsion and their mode of action (MOA) against Fusarium graminearum isolate, a fungal pathogen causing Fusarium Head Blight (FHB) in cereal crops. The HEO, primarily consisting of terpenes and terpenoids, was encapsulated in nanoemulsion droplets. Physically stable HEO-in-water nanoemulsion ...
... The antimicrobial properties of essential oils from spice and medicinal plants have aroused interest for their potential as an alternative to the use of chemical preservatives in foods. In this work, we studied the bacteriostatic and bactericidal effects of Oregano, Thyme, Clove, Cinnamon and Black-pepper essential oils (EOs) against strains of Staphylococcus aureus, Listeria sp, Escherichia coli ...
... Edible vegan films were obtained on the basis of furcellaran and protein hydrolysates from soybean bran. The aim of the study was to investigate the possibility of using innovative single- and double-layer films with antioxidant properties as packaging materials for vegetarian products. A further objective of the study was to evaluate the degree of biodegradation and potential toxicity with regard ...

Abstract:
... Lippia alba (Mill.) N.E.Br. ex Britton & P. Wilson is traditionally used in Brazil as an adjunct in the relief of mild anxiety, as an antispasmodic, and as an antidyspeptic. This medicinal species was included in the Phytotherapeutic Form of the Brazilian Pharmacopeia 2nd edition (2021) and has already been described as the most used medicinal plant in a study with patients from an Anticoagulation ...
... The residues of alfalfa and goldenrod, after supercritical CO₂ extraction, were examined against raw plant materials to determine the capacity to carry micronutrients and energy production. Materials were enriched with Cu(II), Mn(II) and Zn(II), via biosorption and subjected to multielemental analysis and determination of nitrogen. The materials showed a high capacity for Cu(II)>Zn(II) > Mn(II), w ...
... The environmental Kuznets curve has received widespread attention from researchers and policymakers for its ability to vividly capture the dynamics between economy and environment. While attempts have been made to validate the environmental Kuznets curve and harness its explanatory power in different dilemmatic scenarios (e.g., economic development and greenhouse gas induced climate change), these ...

Abstract:
... The step-pool is a representative riverbed structure that is highly effective in increasing flow resistance and dissipating flow energy. Well-designed artificial step-pools can control channel incision, improve riverbed stability, and further mitigate natural hazards. In this study, step-pools following the characteristics of natural step-pools in terms of their geomorphology and energy dissipatio ...
... An enterocin whey solution, obtained by growing Enterococcus faecalis L2B21K3 and L3A21K6 in sweet whey – enterocin whey solution (EWS), was incorporated into gelatin/glycerol films that were tested for the control of Listeria monocytogenes. The films containing enterocins produced by either strain (EWS L2 and EWS K6 films) were shown to serve as a suitable matrix for bacteriocin release, preserve ...

Abstract:
... The layer-by-layer assembly technique was used to synthesize novel multiwalled carbon nanotubes (MWCNTs) on magnetic carbon (Fe₃O₄@C) nanospheres, which were then used to extract six perfluoroalkyl substances (PFAS) in environmental real water samples using ultra high-performance liquid chromatography coupled to tandem mass spectrometry. The as-synthesized sorbent MWCNTs@Fe₃O₄@C was employed for m ...

Abstract:
... Evaluating the protein content of a single chickpea seed in a rapid, non-destructive, and precise manner is crucial for facilitating the breeding of high-protein chickpeas. This study explored the potential of near-infrared (NIR) hyperspectral imaging (HSI) to predict the protein content in a single chickpea seed. Eight varieties of chickpeas with different protein contents were subjected to NIR r ...
... The seas and oceans of the planet provide a wide range of essential resources. However, marine ecosystems are undergoing severe degradation due to the unsustainable exploitation and consumption patterns of the linear economy. On the other hand, many economic activities linked to the sea generate a large amount of waste, leading to negative impacts, such as the cost of treating or disposing of this ...
... In this study, a novel supramolecular solvent based on surface-active ionic liquid was prepared and used as an extraction solvent for dispersive liquid–liquid microextraction of four triazine herbicides in tea samples. The formation mechanism, microstructure and physicochemical properties of supramolecular solvent were studied. Some parameters, including the molar ratio of surface-active ionic liq ...
