Understanding the components of the diet, food groups, and nutritional strategies that help prevent MASLD (Metabolic Dysfunction-Associated Steatotic Liver Disease) is essential for identifying dietary behaviors that can stop the progression of this condition, which currently affects over one-quarter of the global population. This review highlights the importance of including antioxidant nutrients in the diet, such as vitamins C and E, CoQ10, and polyphenolic compounds. It also emphasizes substances that support lipid metabolism, including choline, alpha-lipoic acid, and berberine. Among food groups, it is crucial to choose those that help prevent metabolic disturbances. Among carbohydrate-rich foods, vegetables, fruits, and high-fiber products are recommended. For protein sources, eggs, fish, and white meat are preferred. Among fat sources, plant oils and fatty fish are advised due to their content of omega-3 and omega-6 fatty acids. Various dietary strategies aimed at preventing MASLD should include elements of the Mediterranean diet or be personalized to provide anti-inflammatory compounds and substances that inhibit fat accumulation in liver cells. Other recommended dietary models include the DASH diet, the flexitarian diet, intermittent fasting, and diets that limit fructose and simple sugars. Additionally, supplementing the diet with spirulina or chlorella, berberine, probiotics, or omega-3 fatty acids, as well as drinking several cups of coffee per day, may be beneficial. Full article

Winter squash (Cucurbita moschata Duchesne.) is a vegetable of high socioeconomic importance owing to the nutritional quality of its fruits, seeds, and seed oil. This study aims to review the main aspects related to the characterization, conservation, and breeding of C. moschata, emphasizing the studies with C. moschata accessions maintained by the Vegetable Germplasm Bank of the Federal University of Viçosa (BGH-UFV). Studies on C. moschata germplasm have reported high variability, particularly in Brazil. Currently, Brazil maintains six Cucurbita germplasm collections, kept in research and teaching institutions. The BGH-UFV collection, one of the largest in the country, contains approximately 350 accessions of C. moschata, mostly landraces collected from all over Brazil. Studies characterizing this germplasm have identified promising genotypes as sources of alleles for increasing the carotenoid content in the fruit pulp and oleic acid content in the seed oil. As part of a breeding program to increase seed oil productivity and improve the oil profile, studies with the BGH-UFV germplasm have identified C. moschata genotypes with seed oil productivity of up to 0.27 t ha⁻¹ and accessions producing oil with high oleic acid content (21 to 28%). The genetic breeding program of C. moschata conducted at the UFV has prioritized the development of compact growth habit genotypes to reduce plant spacing and increase seed and oil productivity. The works involving the collection of C. moschata maintained by the BGH-UFV corroborates the importance of this germplasm as a source of alleles for improving seed oil productivity and the oil profile.

The RasGAP SH3 domain binding protein (G3BP) is a highly conserved family of proteins in eukaryotic organisms that coordinates signal transduction and post-transcriptional gene regulation and functions in the formation of stress granules. G3BPs have important roles in abiotic/biotic stresses in mammals, and recent research suggests that they have similar functions in higher plants. Brassica contains many important oilseeds, vegetables, and ornamental plants, but there are no reports on the G3BP family in Brassica species. In this study, we identified G3BP family genes from six species of the U’s triangle (B. rapa, B. oleracea, B. nigra, B. napus, B. juncea, and B. carinata) at the genome-wide level. We then analyzed their gene structure, protein motifs, gene duplication type, phylogeny, subcellular localization, SSR loci, and upstream miRNAs. Based on transcriptome data, we analyzed the expression patterns of B. napus G3BP (BnaG3BP) genes in various tissues/organs in response to Sclerotinia disease, blackleg disease, powdery mildew, dehydration, drought, heat, cold, and ABA treatments, and its involvement in seed traits including germination, α-linolenic acid content, oil content, and yellow seed. Several BnaG3BP DEGs might be regulated by BnaTT1. The qRT-PCR assay validated the inducibility of two cold-responsive BnaG3BP DEGs. This study will enrich the systematic understanding of Brassica G3BP family genes and lay a molecular basis for the application of BnaG3BP genes in stress tolerance, disease resistance, and quality improvement in rapeseed.

Improving the quality of compounds in medicinal and aromatic plants is crucial due to their uses in the pharmaceutical, cosmetics, and food sectors. One way of influencing plant composition is through exposure to different light conditions. Therefore, a two-year field study (2023–2024) was conducted to investigate the impact of coloured shading nets on the physiology, essential oil (EO) content, and composition of three Mentha genotypes: Mentha × piperita ‘Multimentha’, Mentha × piperita ‘Fränkische Blaue’, and Mentha rotundifolia ‘Apfelminze’. In addition to an unshaded control, the Mentha plants were grown under red and blue shading nets. Plant height and vegetation indices were collected weekly. Biomass accumulation, EO content, and composition were determined for each harvest. Both red and blue shading were found to influence the physiological responses and EO compositions of the plants, with red shading promoting slightly higher p-menthone levels in ‘Fränkische Blaue’ and ‘Multimentha’, while blue shading slightly increased carvone levels in ‘Apfelminze’. While EO content varied across harvest seasons (spring, summer, and autumn), ‘Fränkische Blaue’ responded to red shading, demonstrating an increased EO content. The findings suggest that targeted use of coloured shading nets can modulate EO quality. However, genotype-specific responses highlight the necessity of further research to define shading applications for different species and genotypes. Full article

This review examines the chemical functionalization of Camelina, hemp, and rapeseed oils for the development of sustainable bio-based resins. Key strategies, including epoxidation, acrylation, and click chemistry, are discussed in the context of tailoring molecular structure to enhance reactivity, compatibility, and material performance. Particular emphasis is placed on overcoming the inherent limitations of vegetable oil structures to enable their integration into high-performance polymer systems. The agricultural sustainability and environmental advantages of these feedstocks are also highlighted alongside the technical challenges associated with their chemical modification. Functionalized oils derived from Camelina, hemp, and rapeseed have been successfully applied in various resin systems, including protective coatings, pressure-sensitive adhesives, UV-curable oligomers, and polyurethane foams. These advances demonstrate their growing potential as renewable alternatives to petroleum-based polymers and underline the critical role of structure–property relationships in designing next-generation sustainable materials. Ultimately, the objective of this review is to distill the most effective functionalization pathways and design principles, thereby illustrating how Camelina, hemp, and rapeseed oils could serve as viable substitutes for petrochemical resins in future industrial applications.

The aim of this study was to determine the intraspecific variability among 11 wild-growing populations of wormwood (Artemisia absinthium L.) originating from Central Europe and preserved in the Polish Genebank Collection. The populations were introduced into ex situ conditions, and assessed in terms of selected developmental and chemical traits (essential oil, phenolic acids, polyphenols, and tannins content). Developmental observations and harvest of raw materials were carried out in the second year of plant vegetation, at the beginning of flowering. The populations exhibited significant differences. The greatest variability was observed in the number of shoots per plant (38–51) and dry mass of herb per plant (0.83–1.60 kg). Essential oil (EO) content ranged from 0.75 to 1.69 g/100 g dry weight (DW). A total of 41 compounds were identified in the EOs, with oxygenated monoterpenes (such as sabinyl acetate, cis-chrysanthenol, chrysantenyl acetate, 1,8-cineole, α- and β-thujone) as dominants, showing considerable variation among populations. Based on the EO profiles, several chemotypes were distinguished, mainly (1) a pure sabinyl acetate chemotype; (2) mixed chemotypes with sabinyl acetate accompanied by β-myrcene, cis-chrysanthenol, chrysanthenyl acetate, or 1,8-cineole; and (3) a thujone chemotype. The total content of phenolic acids (expressed as caffeic acid equivalent), tannins, and polyphenols (as pyrogallol equivalent) varied significantly, too (0.37–0.50; 0.10–0.26; 0.58–0.79%, respectively). The results confirm a high level of intraspecific variability in both developmental and chemical traits of A. absinthium populations originating from Poland. This diversity may be valuable for future breeding programs and for the selection of populations with desired phytochemical profiles for medicinal, food, and agricultural applications. It is worth noting that the floristic diversity among populations indicates the habitat heterogeneity, ranging from natural or semi-natural (populations 1, 6) to more anthropogenically influenced ones (populations 2, 4, 5, 7–11).

As a large class of natural organic compounds, vegetable oil is generally composed of 95% fatty acid triglycerides and very few complex non-triglycerides. It has many advantages, such as sufficient yield, low price, distinct structural characteristics, and biodegradability. UV curing technology is known as a new method for the green industry in the 21st century due to its high efficiency, economy, energy conservation, high adaptability, and environmental friendliness. Therefore, UV-curable resins based on UV-curing technology has attracted widespread attention, converting epoxy soybean oil, castor oil, tung oil and other vegetable oils into high-performance plant oil-based UV-curable resins with higher molecular weight, multi-rigid ring and high reactivity, and the curing performance has been greatly improved, and the technology has been widely used in the field of polymer materials such as coatings, inks and adhesives. In this article, the recent research progress on this topic was summarized, and emphasis was put on the research on the resins from soybean oil and castor oil. Full article

Thrips parvispinus (Karny) is an invasive pest of vegetable and ornamentals in the United States. To support ornamental growers to control T. parvispinus infestations, we tested seven conventional (spinosad, chlorfenapyr, sulfoxaflor–spinetoram, pyridalyl, tolfenpyrad, abamectin, and cyclaniliprole–flonicamid) and two biorational insecticides (mineral oil and sesame oil) under greenhouse conditions on mandevilla (Mandevilla splendens) and gardenia (Gardenia jasminoides), primary T. parvispinus ornamental hosts. Two insecticide applications were performed: a curative, treating an existing infestation, and a prophylactic, treating a plant prior to the thrips release. In the curative application, ten larvae and ten adults were released two weeks prior to treatment. Three leaves from the upper, middle, and lower canopy were collected 24 h, 7-, and 14-days post-treatment to assess thrips mortality. In the prophylactic application, plants were first sprayed with insecticides, and thrips were introduced 24 h later, but followed the same sampling method. In mandevilla, chlorfenapyr, abamectin, and spinosad caused the highest thrips mortality in both application types. Among horticultural oils, mineral oil and sesame oil increased mortality in prophylactic applications only. In gardenia, neither curative nor prophylactic applications of these products led to significant thrips mortality, and the possible reasons and recommendations for best thrips management are presented.

The effect of white and additional red and blue LED lighting at night (Blue-NLL, Red-NLL) and during the pre-harvest period (Blue-P-hLL, Red-P-hLL) on morphological and physiological parameters, elemental composition, content of polyphenols, and essential oils of purple basil cultivars ‘Ararat’ and green basil ‘Tonus’ grown in the hydroponic conditions of the climatic chamber was studied. The height of the plants was determined by the variety and the LED irradiation period. The highest purple basil plants were obtained in the variant with Blue-NLL illumination; the highest green basil plants were obtained under Blue-P-hLL and Red-P-hLL. The red spectrum, regardless of the lighting period and variety, increased the area and number of leaves, biomass, and vegetative productivity. Significant changes in the elemental composition of the vegetative mass of basil varieties were determined by the period of exposure to the red spectrum. Red-P-hLL stimulated the absorption and accumulation of Mg, Ca, S, and P from the nutrient solution, and Red-P-hLL reduced the nitrate content by more than 30.00%. Blue-NLL lighting increased the content of quercetin, rosmarinic acid, and essential oil and reduced the nitrate content in the vegetative mass by more than 40.00%. The effectiveness of the white LED was observed in increasing the vegetative mass of ‘Tonus’. The results of this study will be in demand in the real sector of the economy when improving resource-saving technologies for growing environmentally friendly leafy vegetable crops with improved chemical composition and high vegetative productivity.

Background: Understanding the absorption and distribution of herbicides in plants and animal tissues is essential for assessing their potential risks to human health. Method: In this study, we employed imprint desorption electrospray ionization mass spectrometry imaging (IDESI-MSI) to visualize in both vegetable and animal tissues the absorption of Roundup which is a widely used herbicide. Results: Using IDESI-MSI with a pixel size of 150 µm, we detected the herbicide alongside several endogenous metabolites on oil-absorbing films applied to carrot sections. Time-course experiments revealed progressive herbicide penetration into carrot tissue, with penetration depth increasing linearly over time at a rate of approximately 0.25 mm/h. In contrast, green pepper samples showed minimal herbicide infiltration, likely owing to their hydrophobic cuticle barrier. Additionally, mice fed with herbicide-treated carrots exhibited detectable levels of herbicide in liver and kidney tissues. Conclusions: These findings highlight the utility of IDESI-MSI as a powerful analytical platform for the rapid evaluation of chemical migration and absorption in food and biological systems, with important implications for food safety and toxicological research.

Neurodegenerative disorders, mental conditions, and cognitive decline represent significant challenges worldwide, with growing pieces of evidence implicating alterations in neurotrophin signaling as central to these diseases. Neurotrophins—such as nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF)—are indispensable for neuronal survival, differentiation, and synaptic plasticity, and their dysregulation is closely associated with various neuropathological situations. Similarly, dietary plant polyphenols, abundant in vegetables, fruits, wine, tea, and extra virgin olive oil, show powerful anti-inflammatory, antioxidant, and anti-apoptotic activities. This narrative review critically addresses the evolving body of evidence that links plant polyphenols and brain neurotrophins, emphasizing several molecular mechanisms by which polyphenols regulate and modulate neurotrophin signaling. Crucial pathways include mitigation of neuroinflammatory responses, activation of intracellular cascades such as the cAMP response element-binding protein (CREB), epigenetic modulation, and the diminution of oxidative stress. Together, these effects contribute to potentiated enhanced synaptic function, neuronal integrity, and better learning and memory processes. Moreover, this narrative review examines how polyphenol-induced upregulation of neurotrophins may alleviate conditions associated not only with neurodegeneration but also with addiction and mood disorders, suggesting extensive therapeutic approaches. Findings from clinical investigations and animal models are presented to sustain the neuroprotective role of polyphenol-rich diets. Lastly, future research directions are recommended, focusing on polyphenol bioavailability optimization, considering combinatory dietary stratagems, and proposing personalized nutritional interventions. This wide-ranging perspective highlights plant polyphenols as encouraging modulators of neurotrophin pathways and supports their inclusion in approaches aimed at promoting brain health and counteracting neurodegenerative decline.

The Arctic region is rich in oil and gas resources and has great potential for development. It has become a new hot spot for international development. However, the harsh climatic and geological conditions and fragile ecosystems in the Arctic region put forward stringent technical requirements for oil and gas development. Polar permafrost has an impact on the growth of plant roots and the absorption of water. When drilling activities are carried out, the permafrost layer may be broken, resulting in the erosion of polar soil and disorder of the water balance, thus affecting local vegetation and ecosystems. Moreover, the legal system of polar environmental protection is lacking, and it is necessary to form a perfect risk assessment method to improve the relevant laws and regulations. Therefore, it is very important to study the environmental risk identification technology for polar drilling. For polar drilling, it is necessary to establish a risk source classification and identification method for environmental pollution events. However, at present, it mainly faces the following challenges: poor polar environment, lack of monitoring data, and lack of a legal system for polar environmental protection. By systematically discussing risk identification technology, the application and applicable models of different types of risk evaluation methods are categorized and summarized, the advantages and disadvantages of different types of risk evaluation methods and their application effects are analyzed based on the unique environment of the polar regions, and then the development direction of the future environmental risk identification technology for polar drilling is proposed. In order to accelerate the development of polar drilling environmental risk identification technology, research should be focused on the following three aspects: ① Promoting the multi-dimensional integration of polar drilling environmental pollution index data, to make up for the short board of less relevant data in the polar region. ② Combining the machine modeling algorithm with risk evaluation of polar drilling environmental pollution to improve the scientificity and accuracy of the evaluation results. ③ Establishing a scientific and accurate polar drilling environmental pollution risk identification system to reduce pollution risk.

Background/Objectives: Recent decades have seen a remarkable westernization of diets and a decline in adherence to the Mediterranean diet (MD). This study examined the eating habits of a representative sample of Italian university students to identify the determinants of adherence to the MD and the most relevant actions to improve their well-being. Methods: The Mediterranean Diet Quality Index for Children and Adolescents (KIDMED) and Sustainable Healthy Diet (SHED) index questionnaires were used to explore MD adherence as the primary outcome, and dietary behavior sustainability, respectively. Sociodemographic, anthropometric, and lifestyle information was also collected. Results: The final sample included 1434 subjects (18–24; 60% female). The median (IQR) KIDMED score was 6.0 (4.0–8.0) and 33% showed a high adherence to the MD. Having breakfast, eating fruit and vegetables at least once a day, consuming pasta or other grains almost daily, and using olive oil at home were among the most common positive aspects of students’ diets. However, regular consumption of fish, nuts, legumes, dairy products, and a second serving of fruit and vegetables was less prevalent. Having an active lifestyle, eating more plant products, and having more sustainable dietary behaviors in terms of the SHED index, were the main determinants of a high KIDMED score. Likewise, graduate students, daily consumers of plant-based meat alternatives, and students attending university canteens daily were more likely to adopt healthier diets. Conclusions: Future actions are crucial to create a food environment that facilitates healthy and sustainable dietary choices among young adults, such as improving the nutritional quality of processed products and regulating their promotion, as well as implementing initiatives to improve university food services and encourage the use of campus dining facilities.

Meat plays a key role in human nutrition, providing protein of high digestibility and essential micronutrients. However, according to the FAO and WHO, excessive consumption of red and processed meats may increase health risks due to their content of saturated fats, sodium, and E-number additives. For this reason, recent research has focused on the nutritional reformulation of meat products to develop functional and health-promoting alternatives that meet consumer expectations and respond to market trends for healthier and more sustainable foods. However, the addition or elimination of traditional ingredients in meat products leads to problems such as changes in texture, color, or sensory acceptability that must be solved. This review will focus on current reformulation strategies in the meat industry, including the reduction or replacement of animal fat with vegetable oils using technologies such as microencapsulation, or the elaboration of 3D gels using organogelants and hydrocolloids; the replacement of the umami flavor of salt with extracts from seafoods and mushrooms; the replacement of E-number additives with antioxidant and preservative extracts from plants and herbs; and the incorporation of dietary fiber through fruit peels and vegetable by-products.

This study investigated the effects of three mulch types (straw, vermicompost and “plastic”) plus an untreated control, and three irrigation regimes (RFD: rainfed conditions; SIF: one supplemental irrigation at the flowering stage; SIVF: two supplemental irrigations at the vegetative and flowering stages) on the growth, seed yield, oil composition, and biochemical status of linseed (Linum usitatissimum L.). Linseed plants were best affected by SIVF and straw mulch in terms of seed yield (300 and 222.4 g m⁻², respectively), biomass yield (887.9 and 703 g m⁻², respectively), and concentration of oleic and linoleic acids. Under rainfed conditions, “plastic” mulch application increased stearic acid concentrations, while SIF increased palmitic acid concentrations. Rainfed conditions promoted the accumulation of proline (10.1 μmol g⁻¹ fresh weight), total phenols (6.68 mg g⁻¹ fresh weight), and DPPH radical scavenging capacity (56.5%). Under RFD, plants grown in straw-mulched soil showed the highest total phenol content and DPPH radical scavenging capacity, while control (unmulched) plants displayed the highest proline concentration at this irrigation regime. Enzyme activities, including catalase and superoxide dismutase, were enhanced under straw and “plastic” mulch compared to control plants under rainfed conditions. Our findings suggest that straw mulch represents an effective, sustainable strategy to successfully manage linseed crops, mitigating the adverse effects of water deficit stress on plant performance.
