Full-scale validation of bio-recycled asphalt mixtures for road pavements
2019
Abstract Recycling of asphalt has become a well-established practice in many countries, however the road pavement industry remains a bulk consumer of extracted raw materials. Novel solutions that find root in circular economy concepts and life-cycle approaches are needed in order to enable optimisation of infrastructure resource efficiency, starting from the design stage and spanning the whole value chain in the construction sector. Itis within this framework that the present study presents a full-scale validation of asphalt mixtures specifically designed to ensure durability of flexible road pavements and at the same time enabling the reuse of reclaimed asphalt pavement (RAP) through the i…
The effect of experimental lead pollution on DNA methylation in a wild bird population
2021
Anthropogenic pollution is known to negatively influence an organism’s physiology, behaviour, and fitness. Epigenetic regulation, such as DNA methylation, has been hypothesized as a potential mechanism to mediate such effects, yet studies in wild species are lacking. We first investigated the effects of early-life exposure to the heavy metal lead (Pb) on DNA methylation levels in a wild population of great tits (Parus major), by experimentally exposing nestlings to Pb at environmentally relevant levels. Secondly, we compared nestling DNA methylation from a population exposed to long-term heavy metal pollution (close to a copper smelter), where birds suffer from pollution-related decrease in…
Flow-cytometric enumeration of reticulocytes with the new fluorochrome 1′,3′-diethyl-4,2′-quinolylthiacyanine
1992
Several flow-cytometric methods for reticulocyte enumeration in whole blood have been developed, with different degrees of practical use. Recently, a new fluorochrome, 1′,3′-diethyl-4,2′-quinolylthyacianine (DEQTC) was proposed in a brief report, as an alternative to thiazole orange for reticulocyte counting. We have evaluated the usefulness of this fluorescent stain by assessing the optimal conditions for the flow-cytometric analysis, and by comparing in double-blind assays the quantitative results of this technique with those obtained by manual counting with brilliant cresyl blue. Our results show that flow cytometry with DEQTC is highly correlated to the manual method (r=0.95–0.99), supp…
Global data on earthworm abundance, biomass, diversity and corresponding environmental properties
2021
Earthworms are an important soil taxon as ecosystem engineers, providing a variety of crucial ecosystem functions and services. Little is known about their diversity and distribution at large spatial scales, despite the availability of considerable amounts of local-scale data. Earthworm diversity data, obtained from the primary literature or provided directly by authors, were collated with information on site locations, including coordinates, habitat cover, and soil properties. Datasets were required, at a minimum, to include abundance or biomass of earthworms at a site. Where possible, site-level species lists were included, as well as the abundance and biomass of individual species and ec…
Dalle Cronache del mal d’amore al ciclo dell’Amica geniale: continuità ed evoluzione nella narrativa di Elena Ferrante
2019
The paper analyzes the whole narrative production of Elena Ferrante, emphasizing its unity and cohesion. Cohesion coexists with discontinuity: the publication of My Brilliant Friend marks an inventive turning point and reveals new strategies. But it’s even remarkable Ferrante’s predilection for a narrative in which «the flow of storytelling that despite its density manages to sweep you away».
The role of intact oleosin for stabilization and function of oleosomes.
2013
Lipid storage in plants is achieved among all plant species by formation of oleosomes, enclosing oil (triacylglycerides) in small subcellular droplets. Seeds are rich in this pre-emulsified oil to provide a sufficient energy reservoir for growing. The triacylglyceride core of the oleosomes is surrounded by a phospholipid monolayer containing densely packed proteins called oleosins. They are anchored in the triacylglycerides core with a hydrophobic domain, while the hydrophilic termini remain on the surface. These specialized proteins are expressed during seed development and maturation. Particularly, they play a major role in the stabilization and function of oleosomes. To better understand…
Removal of Brilliant Green Dye from Water Using Ficus benghalensis Tree Leaves as an Efficient Biosorbent
2023
The presence of dyes in water stream is a major environmental problem that affects aquatic and human life negatively. Therefore, it is essential to remove dye from wastewater before its discharge into the water bodies. In this study, Banyan (Ficus benghalensis, F. benghalensis) tree leaves, a low-cost biosorbent, were used to remove brilliant green (BG), a cationic dye, from an aqueous solution. Batch model experiments were carried out by varying operational parameters, such as initial concentration of dye solution, contact time, adsorbent dose, and pH of the solution, to obtain optimum conditions for removing BG dye. Under optimum conditions, maximum percent removal of 97.3% and adsorption…
Alternative for improving gut microbiota: use of Jerusalem artichoke and probiotics in diet of weaned piglets
2014
AbstractThe aim of the study was to determine the effect of Jerusalem artichoke and probiotics on defence activity of intestinal cells of weaning pigs. One hundred eighty piglets (7 weeks old) were fed with basal feed supplemented with Jerusalem artichoke, Lactobacillus reuteri and Pediococcus pentosaceus. After 5 weeks, the piglets were slaughtered and the gastrointestinal contents and intestine samples were taken for analysis. Results demonstrated that in pigs fed basal diet with both probiotics and Jerusalem artichoke (5% of basal diet) (T3 group) had less (P<0.05) faecal Enterobacteriaceae microorganisms and coliforms and had more (P<0,05) faecal Lactobacillus than in pigs from ot…
Phytochemical-rich extracts of Helianthemum lippii possess antimicrobial, anticancer, and anti-biofilm activities
2022
Helianthemum lippii is a perennial shrubby plant growing in the sandy environments of Italy, Mediterranean countries of North Africa and Middle East. H. lippii is used in traditional medicine but there are very few reports referring to the phytochemical characterization, the ethnopharmacology, and the biological activity of H. lippii. The goal of this study was todetermine the phytochemical composition of different H. lippii extracts, cold (CME) and hot (HME) methanol, cold (CPEE) and hot (HPEE) petroleum ether, as well as to evaluate their anticancer and antimicrobial activities and biofilm formation reduction. Fifty-fours phytocompounds have been determined by HPLC-UV-ESI-QTOF-MS analysis…
