    Food plants biofortification for micronutrients is a tool for the nutritional value improvement of food. Soilless cultivation systems, with the optimal control of plant nutrition, represent a potential effective technique to increase the beneficial element content in plant tissues. Silicon (Si), which proper intake is recently recommended for its beneficial effects on bone health, presents good absorption in intestinal tract from green bean, a high-value vegetable crop. In this study we aimed to obtain Si biofortified green bean pods by using a Si-enriched nutrient solution in soilless system conditions, and to assess the influence of boiling and steaming cooking methods on Si content, color parameters and Si bioaccessibility (by using an in vitro digestion process) of pods. The Si concentration of pods was almost tripled as a result of the biofortification process, while the overall crop performance was not negatively influenced. The Si content of biofortified pods was higher than unbiofortified also after cooking, despite the cooking method used. Silicon bioaccessibility in cooked pods was more than tripled as a result of biofortification, while the process did not affect the visual quality of the product. Our results demonstrated that soilless cultivation can be successfully used for green bean Si biofortification

    Biodiversity of vegetable crops, a living heritage

    Get PDF
    Biodiversity is the natural heritage of the planet and is one of the key factors of sustainable development, due to its importance not only for the environmental aspects of sustainability but also for the social and economic ones. The purpose of this Special Issue is to publish high-quality research papers addressing recent progress and perspectives while focusing on different aspects related to the biodiversity of vegetable crops. Original, high-quality contributions that have not yet been published, or that are not currently under review by other journals, have been gathered. A broad range of aspects such as genetic, crop production, environments, customs and traditions were covered. All contributions are of significant relevance and could stimulate further research in this area

    Insights into the Sesquiterpenoid Pathway by Metabolic Profiling and De novo Transcriptome Assembly of Stem-Chicory (Cichorium intybus Cultigroup "Catalogna")

    Stem-chicory of the "Catalogna" group is a vegetable consumed for bitter-flavored stems. Type and levels of bitter sesquiterpene lactones (STLs) participate in conferring bitterness in vegetables. The content of lactucin-and lactucopocrin-like STLs was higher in "Molfettese" than "Galatina" landrace stalks, regardless of the cultivation sites, consistently with bitterness scores and gustative differences. The "Galatina" transcriptome assembly resulted in 58,872 unigenes, 77% of which were annotated, paving the way to molecular investigation of the STL pathway. Comparative transcriptome analysis allowed the identification of 69,352 SNPs and of 1640 differentially expressed genes that maintained the pattern independently of the site. Enrichment analyses revealed that 4 out of 29 unigenes were up-regulated in "Molfettese" vs "Galatina" within the sesquiterpenoid pathway. The expression of two germacrene A -synthase (GAS) and one -oxidase (GAO) genes of the costunolide branch correlated positively with the contents of lactucin-like molecules, supporting that STL biosynthesis regulation occurs at the transcriptional level. Finally, 46 genes encoding transcription factors (TFs) maintained a differential expression pattern between the two varieties regardless of the growth site; correlation analyses among TFs, GAS, GAO gene expressions and STLs contents suggest that one MYB and one bHLH may act in the pathway

    Purpose: COVID-19 pandemic transformed the health system response worldwide. The aim of this study is to report changes about numbers and reason for ENT consultations in emergency department (ED) during COVID-19 pandemic comparing with those occurred the previous year (2019). Methods: Data about patients admitted to adult and pediatric ED were collected from March 1 to May 31, 2019 and 2020. Patients referred for urgency from general practitioners were excluded from the study. Results: Global ED admission (except for dyspnea or COVID-19–related symptoms) dramatically decreased during pandemic (−50.9% among adults and −71.4% among pediatrics). At the same time, ENT consultancy significantly reduced too, by 71.5% ( P < .01) among adults and 45.1% ( P < .01) for pediatrics. Among adults, it was reported a statistically significant decrease in consultation for ear problems (−88.5%, P = .0146). Reduction in ENT referral for bone fracture (−40%, P = .059), vertigo (−77.8%, P = .637), and tonsillitis (−87.5%, P = .688) was consistent, but not significant. Among pediatric patients, it was observed an increase by 25% about foreign bodies (12 vs 15, P < .01). A reduction in numbers of consults for ear problem (−90.8%; P = .045), epistaxis (−80%; P = .196), and nasal fracture (−70%; P = .36) was also observed. Conclusion: Fear of infection and the forced lock down caused a significant decrease in the number of ED accesses and in ENT consultancy. These data may suggest that some ED referral usually could be deferred, but on the other hand, pandemic will cause a great diagnostic delay

    Microgreens garner immense potential for improving the nutritional value of the human diet, considering their high content of healthy compounds. On the other hand, they are gaining more and more interest not only for their nutritional value but also for their interesting organoleptic traits and commercial potential. The purpose of this Special Issue is to publish high-quality research papers with the aim to cover the state-of-the-art, recent progress and perspectives related to production, post-harvest, characterization, and potential of microgreens. A broad range of aspects such as cultivation, post-harvest techniques and packaging, analytical methods, nutritional value, bioaccessibily and prospects are covered. All contributions are of significant relevance and could stimulate further research in this area
