    Abstract Microalgae-based wastewater treatment is a promising platform since it enables nutrient recovery. The use of filamentous algae could improve this technology by reducing harvesting cost and enhancing biomass management. The potential of 12 unicellular and 12 filamentous algae strains was evaluated for the treatment and nutrient recovery of a raw wastewater from a slaughterhouse (RWS). Chlorococcum sp. FAUBA-42 (unicellular) and Stigeoclonium sp. FAUBA-10 (filamentous) were selected due to their biomass production using RWS as the sole nutrient source. Comprehensive analysis of batch and semicontinuous regime was carried out for both strains. Semicontinuous cultures showed three times higher biomass productivity than batch regime. The highest biomass productivity (0.45 g DW L⁻¹ d⁻¹) and photosynthetic quantum yield (1.6 g DW mol photons⁻¹) was reached by the filamentous strain Stigeoclonium FAUBA-10 under 2.5 d HRT. Both strains showed nutrient removal above 92% under 5 d and 2.5 d HRT. Biomass of Stigeoclonium FAUBA-10 can be easily harvested by filtration through mesh screens (<341 μm) which is an operational benefit.

    Abstract Decomposition of plant debris is an important process in determining the structure and function of aquatic ecosystems. The aims were to find a mathematic model fitting the decomposition process of Schoenoplectus californicus shoots containing different Zn concentrations; compare the decomposition rates; and assess metal accumulation/mobilization during decomposition. A litterbag technique was applied with shoots containing three levels of Zn: collected from an unpolluted river (RIV) and from experimental populations at low (LoZn) and high (HiZn) Zn supply. The double exponential model explained S. californicus shoot decomposition, at first, higher initial proportion of refractory fraction in RIV detritus determined a lower decay rate and until 68 days, RIV and LoZn detritus behaved like a source of metal, releasing soluble/weakly bound zinc into the water; after 68 days, they became like a sink. However, HiZn detritus showed rapid release into the water during the first 8 days, changing to the sink condition up to 68 days, and then returning to the source condition up to 369 days. The knowledge of the role of detritus (sink/source) will allow defining a correct management of the vegetation used for zinc removal and providing a valuable tool for environmental remediation and rehabilitation planning.

    Abstract The remediation of contaminated dredged sediments is necessary to eliminate the risk towards human beings or the environment when there is disposal on land. A greenhouse experiment was carried out to evaluate the chemically assisted phytoextraction to clean up dredged sediment contaminated with Cr, Cu, Pb, and Zn. The ability of castor bean and chicory to absorb, translocate, and accumulate metals from sediment to root and shoot was evaluated by applying EDTA (5 mM), NTA (5 mM), and citric acid (60 mM) to sediment, before the harvest. Citric acid 60 mM was the most effective treatment in increasing Cr, Cu, and Pb in castor bean and chicory shoot. Chicory could accumulate 1730 mg Cr kg

    Abstract The genus Golenkinia has not been studied for the production of metabolites of commercial interest. In this work, the accumulation and composition of oils and carotenoids was studied in a new isolated strain of the green alga Golenkinia sp. under salinity stress. Both the molecular and morphological characterization of the strain allowed us to identify it tentatively as G. brevispicula. As part of our morphological descriptions, we show previously unreported cellular stages. One of the most remarkable findings relates to the unprecedented observation of a reddish aplanospore stage in a Golenkinia strain resistant to desiccation. Salinity stress induced an increase in total lipids, reaching 37.2% of DW, and an increase in total carotenoids at the end of stress phase. According to the high lipid values with an equilibrated proportion of polyunsaturated fatty acids and the content of carotenoids dissolved in oil droplets, the lipids of this strain could have a potential application in the nutraceutical and aquaculture feed fields. Further studies are being conducted to optimize the growth and stress conditions in order to enhance biomass, oil and carotenoid productivity.

    Abstract The aim of this study was to investigate the parameters of chemical extraction associated with the detection of toxicity and genotoxicity in sediment sample extracts. Quantitative analysis of metals and polycyclic aromatic hydrocarbons (PAHs), together with a battery of four bioassays, was performed in order to evaluate the extraction efficiency of inorganic and organic toxicants. The extracts were carried out using two inorganic solvents, two organic solvents and two extraction methodologies, making a total of five extracts. Two toxicity tests, the algal growth inhibition of Pseudokirchneriella subcapitata and the root elongation inhibition of Lactuca sativa, and two genotoxicity tests, the analysis of revertants of Salmonella typhimurium and the analysis of micronuclei and chromosomal aberrations in Allium cepa, were performed. According to the chemical analysis, the acidic solution extracted more heavy metal concentrations than distilled water, and dichloromethane extracted more but fewer concentrations of PAH compounds than methanol. Shaker extracts with distilled water were non-toxic to P. subcapitata, but were toxic to L. sativa. The acidic extracts were more toxic to P. subcapitata than to L. sativa. The methanolic organic extracts were more toxic to the alga than those obtained with dichloromethane. None of these extracts resulted toxic to L. sativa. Mutagenic effects were only detected in the organic dichloromethane extracts in the presence of metabolic activation. All the inorganic and organic extracts were genotoxic to A. cepa. This study showed that the implementation of different extraction methods together with a battery of bioassays could be suitable tools for detecting toxicity and genotoxicity in sediment samples.

    Abstract This study assessed the contamination by heavy metals (Cr, Cu, Pb, Zn), and nutrients (N, P) in soils and native plants, and the effect of the concentration of those elements with the density of arbuscular-mycorrhizal (AM) spores in soil and colonization in roots from the riverside of the Matanza-Riachuelo River Basin (MRRB). The concentration of metals and nutrients in soils and plants (Eleocharis montana, Cyperus eragrostis, Hydrocotyle bonariensis) increased from the upper sites (8 km from headwaters) to the lower sites (6 km from the mouth of the Riachuelo River) of the basin. AM-colonization on the roots of H. bonariensis and spore density in soil decreased as the concentrations of metals in soil and plant tissues increased from the upper to lower sites of the basin within a consistent gradient of contamination associated with land use, soil disturbance, population, and chemicals discharged into the streams and rivers along the MRRB. The general trends for all metals in plant tissue were to have highest concentrations in roots, then in rhizomes and lowest in aerial biomass. The translocation (TF) and bioconcentration (BCF) factors decreased in plants which grow from the upper sites to the lower sites of the basin. The plants tolerated a wide range in type and quantity of contamination along the basin by concentrating more metals and nutrients in roots than in aboveground tissue. The AM spore density in soil and colonization in roots of H. bonariensis decreased with the increase of the degree of contamination (Dc) in soil.

    Abstract Covid-19 infection is a multisystem disease more frequent in older individuals, especially in those with multiple chronic diseases. This multimorbid and frail population requires attention and a personalized comprehensive assessment in order to avoid the occurrence of adverse outcomes. As other diseases, the COVID-19 presentation in older patients is often atypical with less severe and unspecific symptoms. These subjects both at home and during hospitalization suffer isolation and the lack of support of caregivers. The geriatric care in COVID-19 wards is often missing. The application of additional instruments would be necessary to facilitate and personalize the clinical approach, not only based on diseases but also on functional status. This narrative review starts from diagnostic evaluation, continues with adapted pharmacologic treatment and ends with the recovery phase targeting the nutrition and physical exercise. We developed a check-list of respiratory, gastro-intestinal and other less-specific symptoms, summarized in a table and easily to be filled-up by patients, nurses and general practitioners. As second step, we reported the clinical phases of this disease. Far to be considered just viral infective and respiratory, this disease is also an inflammatory and thrombotic condition with frequent bacterial over-infection. We finally considered timing and selection of treatment, which depend on the disease phase, co-administration of other drugs and require the monitoring of renal, liver and cardiac function. This underlines the role of age not just as a limitation, but also an opportunity to increase the quality and the appropriateness of multidisciplinary and multidimensional intervention in this population.

    Abstract The series of upgrades to the Large Hadron Collider, culminating in the High Luminosity Large Hadron Collider, will enable a significant expansion of the physics program of the CMS experiment. However, the accelerator upgrades will also make the experimental conditions more challenging, with implications for detector operations, triggering, and data analysis. The luminosity of the proton-proton collisions is expected to exceed $2-3\times10^{34}$~cm$^{-2}$s$^{-1}$ for Run 3 (starting in 2022), and it will be at least $5\times10^{34}$~cm$^{-2}$s$^{-1}$ when the High Luminosity Large Hadron Collider is completed for Run 4. These conditions will affect muon triggering, identification, and measurement, which are critical capabilities of the experiment. To address these challenges, additional muon detectors are being installed in the CMS endcaps, based on Gas Electron Multiplier technology. For this purpose, 161 large triple-Gas Electron Multiplier detectors have been constructed and tested. Installation of these devices began in 2019 with the GE1/1 station and will be followed by two additional stations, GE2/1 and ME0, to be installed in 2023 and 2026, respectively. The assembly and quality control of the GE1/1 detectors were distributed across several production sites around the world. We motivate and discuss the quality control procedures that were developed to standardize the performance of the detectors, and we present the final results of the production. Out of 161 detectors produced, 156 detectors passed all tests, and 144 detectors are now installed in the CMS experiment. The various visual inspections, gas tightness tests, intrinsic noise rate characterizations, and effective gas gain and response uniformity tests allowed the project to achieve this high success rate.
