Biofortification of Lettuce and Basil Seedlings to Produce Selenium Enriched Leafy Vegetables
Selenium (Se) biofortification of plants has been recognized as a good strategy to improve the nutritive value of vegetables and increase Se daily intake in humans. Identifying the most appropriate method to enrich plants is a key issue in the biofortification process. We tested a biofortification technique that produces Se enriched seedlings for transplant, yet barely modifies conventional cultivation techniques. Lettuce (Lactuca sativa L.) and sweet basil (Ocimum basilicum L.) were exposed to selenium by adding 0, 1 and 3 mg L−1 (lettuce) and 0, 2 and 3 mg L−1 (basil) of Se, as sodium selenate, to the growing substrate immediately after sowing. When seedlings reached an appropriate size, they were transplanted into the open field, and plants were grown until maturity. Lettuce and basil seedlings accumulated selenium without any reduction in leaf biomass at maturity. The highest dose of Se induced a higher antioxidant capacity and flavonoid content in both species at both sampling times. At maturity, biofortified plants still showed a higher leaf Se content compared to the control, and would be able to provide from 10% to 17% (lettuce) and from 9% to 12% (basil) of the adequate intake (AI) of Se
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Effects of selenium enrichment of tomato plants on ripe fruit metabolism and composition
Biofortification of Ocimum basilicum L. Plants with selenium
Sweet basil (Ocimum basilicum L.) is an aromatic annual plant belonging to the Lamiaceae family, cultivated and utilized throughout the world. Basil has a culinary value, and pharmaceutical properties. The aromatic oil extracted from its leaves has antioxidant and antimicrobial activity. Selenium (Se) is an essential element for humans, and acts as antioxidant and anticarcinogenic agent. Since healthy nutrient plant compounds are more bioavailable than compounds contained in food supplements, biofortification of fruiting and leafy vegetables with Se is a good way to increase consumption and supplementation of Se by humans. Further, Se appears to be effective in delaying fruit ripening and plant senescence, thus decreasing postharvest losses due to enhanced antioxidation. We investigated the effect of Se addition on production and quality traits of Ocimum basilicum L. 'Tigullio'. Two experiments were conducted on sweet basil seedlings hydroponically grown under greenhouse conditions at rate of 0 (control), 0.5, 1, 2, 4 mg Se L-1. Selenium was added to the nutrient solution as sodium selenate. In order to evaluate the growth, physiology, and nutritional value of basil plants the following parameters were determined at harvest time: plant biomass, antioxidant capacity, total phenols, rosmarinic acid, nitrate, macro- and micronutrients, total chlorophyll and total carotenoid. Our results showed that the addition of selenium significantly and linearly increased the Se content in basil. In general, selenium did not affect the plant biomass and the quality of product. The amount of Se accumulated in plants could provide the rational Se intake for human nutrition in accordance with the recommended dietary allowance (RDA) guidelines
Production of selenium‐biofortified microgreens from selenium‐enriched seeds of basil
BACKGROUND: Microgreens (i.e. tender immature greens) are a popular alternative to sprouts (i.e. germinating seeds) because of their higher content of vitamins, carotenoids and phenols, as well as their lower content of nitrates. Their nutritional value can be improved by biofortification, which increases micronutrient levels during plant growth. Because selenium (Se) plays a significant role in antioxidant defense, biofortificationwith Se is a goodway of improving the nutritional quality of sprouts and microgreens. The present study investigated the production of Se-fortified microgreens from Se-enriched seeds of sweet basil (Ocimum basilicum L.). Thesemicrogreens could be used as new beneficial dietary supplements.
RESULTS: Basil plants were grown in a nutrient solution, containing 0 (control), 4 or 8mg Se L−1 as sodium selenate, to full maturity. Seeds accumulated a high amount of Se and were then used to produce microgreens. The germination index was higher in the seeds from Se-treated plants and the microgreens were enriched in Se. The antioxidant capacity of Se-fortified microgreens was higher compared to the control.
CONCLUSION: The production of microgreens fromSe-enriched seeds could comprise a good system for obtainingmicrogreens with a high nutritional value. Basil plants treated with Se could be used to produce both Se-fortified leaves and microgreens

Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
